Title: Suction catheter holder

Description:
CROSS-REFERENCE TO RELATED APPLICATIONS 
     This is a continuation-in-part of U.S. patent application Ser. No. 17/453,444 filed on Nov. 3, 2021, the content of which is relied upon and incorporated herein by reference in its entirety, and the benefit of priority under 35 U.S.C. § 120 is hereby claimed. 
    
    
     FIELD 
     The present disclosure generally relates to medical equipment, and more particularly to a device for releasably holding and securing an oral suction instrument, and more particularly to a device for releasably holding and securing an oral suction instrument while the user is utilizing the oral suction instrument in an ambulatory environment. 
     BACKGROUND 
     Suction instruments, such as a Yankauer suction catheter, are elongate hollow tubes that are used to suction and remove oropharyngeal secretions, congesting fluids, mucus, or other unwanted debris from the oral passageway of a person in order to prevent aspiration. During some emergency situations, such as when a person suffers cardiac arrest, for example, medical professionals are tasked with transporting the ailing person to a hospital. Typically, the person is carried on a stretcher from their initial location to a medical emergency vehicle, such as an ambulance, and then transported to a hospital or other medical care institution. People suffering from cardiac arrest or other conditions are at risk of involuntarily vomiting or otherwise causing fluids and other stomach contents from their oropharynx or gastrointestinal tract to enter their larynx and lower respiratory tract—a condition called pulmonary aspiration. In some cases, pulmonary aspiration can lead to death from asphyxiation. 
     Emergency medical professionals commonly use suction catheters to remove potential asphyxiants from a patient&#39;s oral passageway. During use, particularly after removing the suction catheter from the patient&#39;s mouth, the tip of the suction catheter may include residual fluids, stomach contents, or other potential asphyxiants. And while the patient is being transported from their initial location to a medical emergency vehicle and eventually to a medical care institution, the suction catheter may be used multiple times to clear the patient&#39;s oral passageway. Existing stretchers and medical emergency vehicles do not have a device for releasably holding and securing a suction catheter during use, so the suction catheter is often stored under the patient&#39;s neck to avoid having it contact the ground or otherwise allowing it to become contaminated. As a result, the medical professionals can be exposed to potentially toxic bodily fluids. For the foregoing reasons, there is a need for an improved suction catheter holder, and more particularly for an improved suction catheter holder that is adapted for use in an ambulatory environment.

     In various embodiments, a suction catheter holder is provided. As shown in  FIGS.  1 - 7   , in some embodiments the suction catheter holder  100  comprises a housing  101  that defines an interior open-space compartment  140  that is configured to receive at least a portion of the suction catheter SC. In some embodiments, the housing  101  is an enclosure for holding the suction catheter SC in a specific, inserted position, particularly while the suction catheter SC is being used, and more particularly while the suction catheter SC is being used during the transport of a patient from their initial location (e.g., home, work, etc.) to a medical treatment facility (e.g., hospital). In such embodiments, when the suction catheter SC is in the specific inserted position, the user and surrounding area would not be exposed to any contaminants remaining on the surface of the suction catheter after it has been used to treat a patient. 
     The housing  101  can be any suitable size and have any suitable shape, wherein the suitability is based on the general size and shape of existing and/or commonly used suction catheters. In some embodiments, for example, the housing  101  comprises an elongate structure, with longitudinal and lateral axes, for accommodating the elongate tubing structure of a suction catheter SC.  FIG.  1    includes a legend defining the longitudinal axis Y, the lateral axis X, and the vertical axis Z. In some embodiments, the interior compartment  140  defined by the three-dimensional structure of the housing  101  is configured about the longitudinal axis Y having a length that is long enough to receive at least a predetermined portion of the suction catheter SC, a lateral axis X having a width that is wide enough to accommodate the elbow shape of the suction catheter SC, and a vertical axis Z having a height that is high enough to accommodate the diametrical height of the suction catheter SC as well as the features of the front sidewall  102  described herein.  FIG.  5   , for example, shows the elbow shape of existing and/or commonly used suction catheters. 
     In various embodiments, the housing  101  is sized to receive a suction catheter (SC,  FIG.  5   ), the suction catheter typically being a disposable, single-use suction catheter having a length about its longitudinal axis in the range of from about 7 inches (about 17.78 cm) to about 11 inches (about 27.94 cm), or from about 8 inches (about 20.32 cm) to about 10 inches (about 25.4 cm), including a length of about 9 inches (about 22.86 cm), about 9.78 inches (about 24.85 cm), etc.; and a width about its transverse axis (i.e., the distance the suction catheter extends at an angle starting from the elbow in its structure, as measured perpendicular from the longitudinal axis) in the range of from about 1 inch (about 2.54 cm) to about 5 inches (about 12.7 cm), or from about 2 inches (about 5.08 cm) to about 4 inches (about 10.16 cm), including, for example, a width of about 2.5 inches (about 6.35 cm), about 3 inches (about 7.62 cm), etc. 
     To accommodate a suction catheter in the range of abovementioned sizes, in some embodiments, the housing  101  has a length L′, width W′, and in height H′, as shown in  FIG.  4   . In some embodiments, the housing  101  has a length L′ in the range of from about 5 inches (about 12.7 cm) to about 10 inches (about 25.4 cm), from about 6 inches (about 15.24 cm) to about 9 inches (about 22.86 cm), or from about 7 inches (about 17.78 cm) to about 8 inches (about 20.32 cm), the ranges including the endpoints, intermediate points, and any subranges thereof, including, for example, a length of about 7.5 inches (about 19.05 cm). In some embodiments, the housing  101  has a width W′ in the range of about 1 inch (about 2.54 cm) to about 4 inches (about 10.16 cm), or from about 1.5 inches (about 3.81 cm) to about 3.5 inches (about 8.89 cm), or from about 2 inches (about 5.08 cm) to about 3 inches (about 7.62 cm), the ranges including the endpoints, intermediate points, and any subranges thereof, including, for example, a width of about 2.5 inches (about 6.35 cm). In some embodiments, the housing  101  has a height H′ in the range of from about 0.5 inches (about 1.27 cm) to about 2 inches (about 5.08 cm), from about 1 inch (about 2.54 cm) to about 1.5 inches (about 3.81 cm), or from about 1.1 inches (about 2.794 cm) to about 1.3 inches (3.302 cm), the ranges including the endpoints, intermediate points, and any subranges thereof, including, for example, a height of about 0.75 inches (1.905 cm) or 1.25 inches (about 3.1765 cm). 
     In some embodiments, the housing  101  has a length L′, width W′, and height H′ in a ratio in the range of from about 10:1:0.5 to about 5:4:2, the range including any ratio at the endpoints, intermediate points, and any subranges within the range, including, for example, the ratios 5.6:2:1; 6:2:1; 9:3:1 (L′:W′:H′). 
     In various embodiments, the housing  101  comprises a base panel  110  that is configured to removably lie on the surface of an object, such as the exposed surface area of the gurney G, as shown in  FIGS.  5 - 7   . In some embodiments, the base panel  110  comprises a flat or substantially flat exterior surface that is configured to lie and remain in a specific, predetermined position without rolling and/or without sliding on or about the surface (e.g., the linen of the gurney). In some embodiments, the housing  101  comprises a plurality of sidewalls ( 102 ,  104 ,  106   a,    106   b ). In such embodiments, each respective sidewall projects transversely about the vertical axis (e.g., obliquely, upward, vertical, orthogonal, substantially orthogonal, etc.) from the base panel  110  toward and to the roof panel  108 . In some embodiments, each sidewall projects transversely about the vertical axis from the outer edges of the base panel  110  toward and to the outer edges of the roof panel  108 . In some embodiments, the roof panel  108  has an exterior surface and an opposing interior surface that faces, at least in part, or at least generally, the interior surface of the base panel  110 . 
     In some embodiments, as shown in  FIGS.  1 - 7   , the housing  101  comprises a rectangular prism shape. In such embodiments, the base panel  110  and the roof panel  108  have identical, or substantially identical, longitudinal and lateral dimensions and each of their respective interior surfaces face one another. In such embodiments, the base panel  110  and the roof panel  108  are separated by a spaced distance defined by the height of the plurality of sidewalls extending about the vertical axis Z. In some embodiments, each of the sidewalls  106   a  and  106   b  extend longitudinally about the longitudinal axis Y, and each of the front and rear sidewalls  102  and  104 , respectively, extend laterally about the lateral axis X. In such embodiments, the longitudinal sidewalls  106   a,    106   b  have identical, or substantially identical, dimensions and their respective interior surfaces face one another. In such embodiments, the longitudinal sidewalls  106   a,    106   b  are separated by a spaced distance defined by the width of the base and roof panels  110 ,  108 . In such embodiments, the front and rear sidewalls  102 ,  104  have identical, or substantially identical, dimensions and their respective interior surfaces face one another. In such embodiments, the front and rear sidewalls  102 ,  104  are separated by a spaced distance defined by the length of the base and roof panels  110 ,  108 . 
     Alternative three-dimensional shapes and configurations for the housing  101  are contemplated. For example, in some embodiments the longitudinal sidewalls  106   a  and  106   b  and/or the front and rear sidewalls  102  and  104 , respectively, can have non-identical (unequal) heights along the vertical axis Z. In another alternative, the front and rear sidewalls  102  and  104  can have non-identical (unequal) lengths about the lateral axis X. In another alternative, the roof panel  108  can have a non-flat configuration, including, for example, an arched, dome shape extending between the longitudinal sidewalls  106   a  and  106   b.  In another alternative, the longitudinal sidewalls  106   a,    106   b  and the front and rear sidewalls  102 ,  104  can define a housing shape and configuration that mimics the long and elbow shape features of a suction catheter so long as there is a flat, or substantially flat, base panel  110  for laying and resting in position on the surface of an object (e.g., gurney). 
     The housing  101  can be comprised of any suitable material. For example, in some embodiments, the housing  101  is comprised of a paper product, such as corrugated fiberboard. In some embodiments, the corrugated fiberboard comprises a coating, which serves as a moisture and/or vapor barrier to preserve the strength of the material when exposed to wet contents and to prevent liquid from leaking through the housing  101 . In some embodiments, the coating is a wax coating or a wax alternative coating. In alternative embodiments, the housing  101  comprises a polymer product, such as a plastic, silicone rubber, or similar material that is moisture- and/or vapor-resistant, or moisture- and/or vapor-proof. In some embodiments, the suction catheter holder  100  is intended to function as a disposable, single-use device. In such embodiments, the suitability of the material for the housing  101  is based on the intended use. 
     In some embodiments, the housing  101  comprises an adhesive material on the external surface of the base panel  110 . Any suitable adhesive material can be used, so long as the material allows a user to removably attach the suction catheter holder  100  to a desired surface (e.g., the linen cloth on a gurney) in a specific, predetermined position. The adhesive material can be applied to the surface of the base panel  110  by any suitable means (e.g., a coating applied via spraying, dispersion, deposition, etc.). In some embodiments, for example, the adhesive material is an acrylate (e.g., methacrylates or epoxy diacrylates) or mixture thereof. 
     In some embodiments, the suction catheter holder  100  comprises a removeable (e.g., peelable) film  114   a  that lays over, covers, and protects the adhesive material on the external surface of the base panel  110 . In such embodiments, the film  114   a  is removed from the external surface of the base panel  110  prior to using the suction catheter holder  100 . In some embodiments, the film  114   a  includes a tab  114   b  to facilitate the removal of the film  114   a  from the suction catheter holder  100 . The film  114   a  and tab  114   b  comprise any suitable material. For example, in some embodiments, the film  114   a  and tab  114   b  are unitarily or independently comprised of coated paper, plastic sheet, or other materials such as those commonly used as a release liner (e.g., super calendered Kraft paper (SCK), glassine, clay coated Kraft paper (CCK), machine finished Kraft paper (MFK), machine glazed paper (MG), biaxially-oriented polyethylene terephthalate (BO-PET), biaxially-oriented polypropylene (BOPP), or other polyolefins comprising high density polyethylene (HDPE), low density polyethylene (LDPE), or polypropylene resins, or some combination thereof. 
     In various embodiments, the housing  101  comprises the front panel  102 , which extends laterally along the respective front edges of the base panel  110  and the roof panel  108 , and between the respective front edges of the longitudinal sidewalls  106   a  and  106   b.  In some embodiments, the front panel  102  comprises the insertion through-hole  120 , which is configured for receiving the tip and tubing portions of the suction catheter SC, and the securing through-hole  130 , which is configured for retaining the tip and tubing portions of the suction catheter SC in a secured position. 
     As shown in  FIGS.  1 - 7   , the housing  101  defines an interior open-space compartment  140  that is configured to receive at least a portion of the suction catheter SC (e.g., the tip portion distal to the elbow and a portion of the shank portion proximal to the elbow). In some embodiments, access to the interior open-space compartment  140  is permitted by the insertion through-hole  120  and/or the securing through-hole  130  on the front sidewall panel  102 . In some embodiments, the insertion through-hole  120  is a relatively large opening and the securing through-hole  130  is a relatively small opening. In some embodiments, the relatively large opening provided by the insertion through-hole  120  is advantageous because it does not require the user to precisely aim the tip of the suction catheter when inserting the same. For example, in an emergency situation—such as when an ambulance is moving in transit and the user is restricted as to where she can physically move within the patient cabin of the vehicle, or generally when the user is riding under stressful or difficult driving conditions—the user can easily insert the suction catheter SC into the insertion through-hole  120 . After the suction catheter SC has been inserted in the interior open-space compartment  140 , it can be moved directly to the securing through-hole  130  via the passage  125  without removing the suction catheter SC from the interior compartment  140 . In some embodiments, the suction catheter SC is forcibly moved by the user from the insertion through-hole  120  to the securing through-hole  130  via the passage  125  while a portion of the suction catheter SC remains inside the interior compartment  140 . In some embodiments, the passage  125  between the adjacent insertion through-hole  120  and securing through-hole  130  creates a unitary through-hole on the front panel  102 . In this context, the unitary through-hole on the front panel  102  comprises a pair of delineated sub-through-holes having a shared edge that is interrupted by the passage  125 . In such embodiments, the insertion through-hole and the securing through-hole are integrated to form a unitary through-hole with two discrete open areas. 
     In various embodiments, the insertion through-hole  120  can have any suitable size and shape. In some embodiments, as shown in  FIG.  2 A , the insertion through-hole  120  comprises a relatively large rectangular shape. In such embodiments, the rectangular shape includes a pair of edges extending about the lateral axis and a pair of edges extending about the vertical axis. In some embodiments, the insertion through-hole  120  comprises an edge extending about the vertical axis Z that is interrupted by the passage  125 . In such embodiments, the passage  125  provides access to the adjacent securing through-hole  130 . In some embodiments, the discrete open area defined by the insertion through-hole  120  is larger than the discrete open area defined by the securing through-hole  130 . 
     Alternative shapes for the insertion through-hole  120  are contemplated. As shown in  FIG.  2 B , the shape of the insertion through-hole  120  can be any suitable shape. In such embodiments, the shape of the insertion through-hole  120  can be determined based on the alternative three-dimensional shapes and configurations of the housing  101  so long as the insertion through-hole  120  and the securing through-hole  130  are adjacent to one another and share a common edge along the vertical axis Z. 
     In various embodiments, as shown in  FIGS.  1 ,  2 A- 2 C,  2 E,  2 F, and  4 - 7   , the securing through-hole  130  comprises a semicircular shape. In this context, “semicircular” refers to an incomplete circle having a circumferential edge that is less than a full circle but more than a half circle. In such embodiments, the semicircular shape is configured to receive and secure a suction catheter SC having a circular cross-sectional shape. In some embodiments, the securing through-hole  130  comprises a diameter that is larger than a diameter of the suction catheter SC. In some embodiments, the securing through-hole  130  comprises a circumferential edge  132  about the circular boundary and further comprises an interruption in the circumferential edge  132  that provides the passage  125 . In such embodiments, the passage  125  provides access to the adjacent insertion through-hole  120 . 
     In some embodiments, as shown in  FIG.  2 A , the securing through-hole  130  has a generally circular or semicircular shape defined by the diameter d and the circumference c, and the insertion through-hole  120  has a generally rectangular or semi-rectangular shape defined by the length l and the width w. Although the generally circular or semicircular securing through-hole  130  is an incomplete circle due to the passage  125 , its two-dimensional area can be approximated in the same manner as a circle, whereby the area (A) is equal to the product obtained by multiplying the number pi (π) times (×) the radius-squared (r 2 ), (A=πr 2 ). And, although the generally rectangular or semi-rectangular insertion through-hole  120  is an incomplete rectangle due to the passage  125 , its two-dimensional area can be approximated in the same manner as a rectangle, whereby the area (A) is equal to product obtained by multiplying the length (l) times (×) the width (w), (A=wl). 
     In various embodiments, the housing  101  is sized to receive a suction catheter (SC) having an external diameter in the range of from about 0.15 inches (about 0.381 cm) to about 0.75 inches (about 1.905 cm), the range including the endpoints, intermediate points, and any subranges thereof, including, for example, about 0.20 inches (about 0.508 cm), about 0.25 inches (about 0.635 cm), about 0.3 inches (about 0.762 cm), about 0.33 inches (about 0.838 cm), about 0.36 inches (about 0.93 cm), about 0.38 inches (about 0.965 cm), 0.5 inches (about 1.27 cm), etc. 
     To accommodate a suction catheter SC having a diameter in the abovementioned sizes, in some embodiments, the securing through-hole  130  has a generally circular or semicircular shape having a diameter din the range of from about 0.17 inches (about 0.432 cm) to about 1.0 inch (2.54 cm), the range including the endpoints, intermediate points, and any subranges thereof, including, for example, from about 0.20 inches (about 0.508 cm) to about 0.75 inches (about 1.905 cm), from about 0.3 inches (about 0.762 cm) to about 0.5 inches (about 1.27 cm), etc., and including, for example, about 0.25 inches (about 0.635 cm). In some embodiments, the securing through-hole  130  has an area in the range of from about 0.0227 in 2  (about 0.147 cm 2 ) to about 0.78 in 2  (about 5.07 cm 2 ), the range including the endpoints, intermediate points, and any subranges thereof, including, for example, about 0.20 in 2  (about 1.27 cm 2 ), about 0.049 in 2  (about 0.317 cm 2 ), and about 0.44 in 2  (about 2.99 cm 2 ). 
     In some embodiments, the insertion through-hole  120  has a generally rectangular shape having a length (l) in the range of from about 0.5 inches (about 1.27 cm) to about 2.0 inches (about 5.08 cm), or from about 1.0 inch (about 2.54 cm) to about 1.5 inches (about 3.81 cm), the ranges including the endpoints, intermediate points, and any subranges thereof, and including, for example, about 1.25 inches (about 3.175 cm). In some embodiments, the insertion through-hole  120  has a generally rectangular shape having a width (w) in the range of from about 0.5 inches (about 1.27 cm) to about 1.5 inches (about 3.81 cm), or from about 0.75 inches (about 1.905 cm) to about 1.25 inches (about 3.175 cm), the ranges including the endpoints, intermediate points, and any subranges thereof, and including, for example, about 1.0 inch (about 2.54 cm). In some embodiments, the insertion through-hole  120  has an area in the range of from about 0.25 in 2  (about 1.61 cm 2 ) to about 3.0 in 2  (about 19.35 cm 2 ), the range including the endpoints, intermediate points, and any subranges thereof, including, for example, 1.25 in 2  (8.0645 cm 2 ). 
     In some embodiments, the discrete open area defined by the insertion through-hole  120  extends laterally across the front sidewall panel  102  from a center portion of the front sidewall to an edge portion proximate to the first respective longitudinal sidewall  106   a.  In such embodiments, for example, if the front sidewall panel  102  is about 3.0 inches in width, then the center portion is the portion approximate to about 1.5 inches from an edge portion proximate to a first respective longitudinal sidewall  106   a.  In some embodiments, the center portion extends up to about 0.5 inches (about 1.27 cm), about 0.4 inches (about 1.016 cm), about 0.3 inches (about 0.762 cm), about 0.2 inches (about 0.508 cm), or about 0.1 inches (about 0.254 cm) from the center line between the longitudinal sidewall  106   a  and  106   b.    
     In some embodiments, the discrete open area defined by the insertion through-hole  120  is substantially larger than the discrete open area defined by the securing through-hole  130  to accommodate the insertion of a suction catheter in an ambulatory environment. In some embodiments, the discrete open area for the insertion through-hole  120  and the discrete open area for the securing through-hole  130  have relative sizes defined by a ratio ( 120 : 130 ), whereby the area for the insertion through-hole  120  is larger than the area for the securing through-hole  130 . For example, the ratio may be 3:1, which means the area for the insertion through-hole  120  is 3-times larger than the area for the securing through-hole  130 . Thus, a ratio defined by two numbers separated by a colon (e.g., 2:1) refers to the relative sizes of the discrete open area defined by the insertion through-hole  120  and the discrete open area defined by the securing through-hole  130 . Example ratios include ratios within the range of from 3.0:0.049 (in 2 ) (19.35:0.317 (cm 2 )) to 1.25:0.44 (in 2 ) (8.06:2.85 (cm 2 )), the range including the endpoints, intermediate points, and any subranges thereof, including, for example, 2:1, 4:1, 5:1, 10:1, etc. 
     In some embodiments, the ratio between the discrete open area defined by the insertion through-hole  120  and the discrete open area defined by the securing through-hole  130  is defined by a single number (e.g., 2.6, 2.7, 2.8, etc.) or a range of numbers (e.g., from 2.5 to 3.0; from 2.6 to 2.9; from 2.7 to 2.8, etc.). In this context, the ratio is the quotient obtained by dividing the discrete open area defined by the relatively larger insertion through-hole  120  by the discrete open area defined by the relatively smaller securing through-hole  130 . For example, in some embodiments, the ratio between the discrete open area defined by the insertion through-hole  120  and the discrete open area defined by the securing through-hole  130  ranges from 2.0 to 10.0, from 2.0 to 8.0, from 2.0 to 7.0, from 2.0 to 6.0, from 2.0 to 5.0, from 2.0 to 4.0; from 2.25 to 3.25; from 2.5 to 3.5, from 2.5 to 3.0; from 2.6 to 2.9; from 2.7 to 2.9; or at least 2.0, at least 2.5, at least 3.1, at least 4.0, etc., whereby the ranges including the endpoints, intermediate points, and any subranges thereof. In some embodiments, the discrete open area defined by the insertion through-hole  120  and the discrete open area defined by the securing through-hole  130  and have relative sizes defined by a ratio of 2.00, 2.10, 2.20, 2.30, 2.40, 2.50, 2.60, 2.70, 2.80, 2.90, 3.00, 3.10, 3.20, etc., including the sub-ratios thereof, such as 2.51, 2.52, 2.53, 2.54, 2.55, 2.56, 2.57, 2.58, 2.59, 2.60, 2.61, 2.62, 2.63, 2.64, 2.65, 2.66, 2.67, 2.68, 2.69, 2.70, 2.71, 2.72, 2.73, 2.74, 2.75, 2.76, 2.77, 2.78, 2.79, 2.80, 2.81, 2.82, 2.83, 2.84, 2.85, 2.86, 2.87, 2.88, 2.89, 2.90, 2.91, 2.92, 2.93, 2.94, 2.95, 2.96, 2.97, 2.98, 2.99, 3.00, 4.00, 5.00, 6.00, 7.00, 8.00, 9.00, etc. 
     In some embodiments, as shown in  FIGS.  2 C and  2 D , the housing  101  comprises a collar  134  along the edge  132  of the securing through-hole  130 . The collar  134  can comprise any suitable material (e.g., silicone, plastic, rubber, etc.). In some embodiments, the material of the collar  134  comprises a sufficient friction coefficient for retaining the suction catheter SC in the securing through-hole  130 , and a sufficient elasticity for allowing the suction catheter SC to the insertion through-hole  120  with the application of force. In such embodiments, the collar  134  comprises a semicircular shape that is consistent with the semicircular shape of the securing through-hole  130 . In such embodiments, the collar  134  comprises a passage  136  that is consistent with the passage  125  between the insertion and securing through-holes  120 ,  130 . In some embodiments, the collar  134  is a grommet having a first flange  135  and a second flange  137  projecting outward from the top and bottom edges, respectively, of a cylindrical structure. In some embodiments, the collar  134  is insertable into the securing through-hole  130  such that the cylindrical structure between the first and second flanges  135 ,  137  is in contact with the diametrical edge  132  of the securing through-hole  130  and the first and second flanges  135 ,  137  are in contact with the interior and exterior surfaces of the front panel  102 . In alternative embodiments, the second flange  137  can be omitted and the collar  135  comprises a “T” cross-sectional shape. In such embodiments, the collar  134  is insertable (e.g., can be forced, pushed, and/or squeezed) into the securing through-hole  130  such that the cylindrical structure is in contact with the circumferential edge  132  of the securing through-hole  130  and the first flange  135  is in contact with the exterior surface of the front panel  102 . In use, the collar  134  provides reinforcing support to the structure of the front panel  102  and particularly to the securing through-hole  130 . 
     In some embodiments, as shown in  FIGS.  2 E and  2 F , the housing  101  comprises a collar  138  lined along the edge of the unitary through-hole comprising the insertion through-hole  120  and the securing through-hole  130 . The collar  138  can comprise any suitable material (e.g., silicone, plastic, rubber, etc.). In some embodiments, the collar  138  is a grommet having a first flange  135 ′ and a second flange  137 ′ projecting outward from its core structure. In some embodiments, the collar  138  is insertable into the unitary through-hole such that the core structure between the first and second flanges  135 ′,  137 ′ is in contact with the edge of the unitary through-hole and the first and second flanges  135 ′,  137 ′ are in contact with the interior and exterior surfaces of the front panel  102 . In alternative embodiments, the second flange  137 ′ is omitted the collar  138  comprises a “T” cross-sectional shape. In such embodiments, the collar  138  is insertable (e.g., can be forced, pushed, and/or squeezed) into the unitary through-hole comprising the insertion through-hole  120  and the securing through-hole  130  such that the core structure is in contact with the edge of the unitary through-hole and the first flange  135 ′ is in contact with the exterior surface of the front panel  102 . In use, the collar  138  provides reinforcing support to the structure of the front panel  102  and particularly to the unitary through-hole comprising the insertion through-hole  120  and the securing through-hole  130 . 
     In some embodiments, the housing  101  comprises an absorbent pad  112 , or a plurality of absorbent pads (e.g.,  112   a,    112   b,    112   c,  etc.) on one or more surfaces of the interior open-space compartment  140 . In some embodiments, as shown in  FIGS.  1  and  3 A , for example, the interior surface of the base panel  110  is covered with the absorbent pad  112 . In some embodiments, the absorbent pad  112  is permanently affixed to the interior surface of the base panel  110 . In some embodiments, the absorbent pad  112  is removably attached to the interior surface of the base panel  110 . In some embodiments, the housing  101  comprises an absorbent pad  112  on a plurality of surfaces of the interior open-space compartment  140 . For example, as shown in  FIG.  3 B , the housing  101  comprises a plurality of absorbent pad ( 112   a,    112   b,    112   c , etc.) on each of the plurality of interior surfaces. In some embodiments, the absorbent pad  112  is comprised of a plurality of separate absorbent pads that are individually and collectively configured to cover, or substantially cover, each interior surface of any base and roof panels and any sidewalls facing the interior open-space compartment  140 . In some embodiments, the absorbent pad  112  is a single structure that is configured to cover, or substantially cover, the interior surfaces of any base and roof panels and any sidewalls facing the interior open-space compartment  140 . In some embodiments, for example, the embodiment shown in  FIG.  3 B  comprising a plurality of individual absorbent pads  112   a,    112   b,    112   c,  etc. is modified to an alternative embodiment having an absorbent pad  112  that is a single structure configured to cover the interior surfaces of each of the base and roof panels and each of the sidewalls facing the interior open-space compartment  140 . 
     In use, due to the nature of the suction catheter&#39;s utility, some moisture including fluids obtained from the patient&#39;s oral cavity can remain in contact with the suction catheter after its removal from the patient&#39;s mouth. In some embodiments, the absorbent pad  112  is configured to absorb such fluids and to reduce the moisture remaining on the surfaces of the suction catheter SC after use. The absorbent pad  112  can be any suitable material for absorbing liquid or semi-liquid (e.g., gel) fluids. In some embodiments, the absorbent pad  112  comprises a plurality of layers. In some embodiments, for example, the absorbent pad  112  comprises fibrous materials including paper, gauze, etc., and/or absorbent technologies such as hydrogels. In some embodiments, the absorbent pad  112  comprises medical-grade materials. In some embodiments, the absorbent pad  112  comprises sterile materials. In some embodiments, the absorbent pad  112  comprises an adhesive material on an exterior surface for attaching to the interior surface of the floor panel  110 . 
     The absorbent pad  112  can be any suitable size and shape. The suitability of the size and shape of the absorbent pad  112  is limited only by the ability to function as an absorbent material for fluids. In some embodiments, the absorbent pad  112  comprises a shape that is consistent with the shape of the floor panel  110 . For example, if the floor panel  110  has a rectangular shape, then the absorbent pad  112  has a rectangular shape. In some embodiments, the absorbent pad  112  covers at least a portion of the interior surface of the floor panel  110 . In some embodiments, the absorbent pad  112  covers the entire interior surface of the floor panel  110 . In some embodiments, the absorbent pad  112  comprises a shape that is consistent with the shape of the interior compartment  140  defined by the housing  101 . 
     In some embodiments, the suction catheter holder  100  can comprise a cover for the insertion through-hole  120  and/or the securing through-hole  130  on the front panel  102 . In such embodiments, the cover can be removably attached to the housing  101  such that when the user has finished using the suction catheter SC, the insertion through-hole  120  and/or the securing through-hole  130  can be covered to prevent the release or spillage of any fluids or biological materials contained therein. 
     The suction catheter holder  100  according to the embodiments described herein can be used to removably and securely hold a suction instruction, including existing and commonly used suction catheters. As would be appreciated by one of ordinary skill in the art, the suction catheter  100  is utilized when it is in proximity to the user and the patient. The user utilizes the suction catheter SC one or more times to clear the oral passageway of the patient, and the suction catheter SC is inserted into the suction catheter holder  100  after or in between the one or more times the suction catheter is used to clear the oral passageway of the patient. During use, the user inserts the tip and shank tubing of the suction catheter SC into the interior open-space compartment  140  via the insertion through-hole  120 . After insertion, the user slidably moves the suction catheter SC through the passage  125  to the securing through-hole  130 , which has a size and shape that restricts the movement of the suction catheter SC. If the user needs to reutilize the suction catheter SC on the patient, then the suction catheter SC is pulled out of the securing through-hole  130  without moving it back to the insertion through-hole  120 . Once the user has finished using the suction catheter  100  it can be disposed of. 
     Exemplary embodiments of the device are described above in detail. The device is not limited to the specific embodiments described herein, but rather, the device may be utilized independently and separately from the other components described herein. For example, the device may also be used in combination with other medical or non-medical instruments and is not limited to its use with the suction catheter SC as described herein. Rather, the exemplary embodiment can be implemented and utilized in connection with other devices. 
     As used herein, the use of examples, or exemplary language (e.g., “such as”), is intended to illuminate the embodiments and does not pose a limitation on the scope of the claims unless otherwise stated. No language in the specification should be construed as indicating any non-claimed element as essential.
