The invention relates to an aspiration module based on a suction (aspiration) pump in accordance with the restrictive part of claim 1 and to a collecting container for receiving liquid in accordance with the restrictive part of claim 14.
For aspiration of body fluids or secrets from body cavities or wounds in medicine, especially in the case of thoracic drainage, stationary aspiration systems have usually been used. Such systems consist essentially of a vacuum source, preferably a vacuum pump, collecting containers for receiving fluid or secret, a buffer tank located between them, and also connecting lines, including a drainage line going from the patient to the container for collecting secret, connecting line going from the container for collecting secret to the buffer tank, as well as the vacuum line connecting the buffer tank and the vacuum source.
Although these suction systems have proven themselves well in practice, during the recovery phase, especially after surgery in the chest cavity, it is very important that the patient can move and leave his bed as early as possible.
In this regard, earlier it was proposed to fix all of the listed components of the drainage system on a movable frame in order to provide the patient with some mobility, at least within the hospital.
Appropriate portable suction modules are known that significantly expand the range of patient mobility. Such portable suction modules are used mainly for drainage of wounds.
However, US 6352525 A describes a portable pump module suitable for thoracic drainage allegedly. It can be fixed on the patient’s body and, therefore, allows him to move freely, almost without any interference. This drainage pump module combines a vacuum pump, an energy source, a vacuum chamber and a secretion container. The vacuum chamber is in the first part of the module, the container for collecting secret is in the second, and the vacuum pump is in the third part. In the working position, the first and third parts are located above the second part and are detachably connected to one another, as well as to the second part. The connection of the corresponding parts is carried out by drainage and vacuum connectors. This device has a relatively complex design and, in addition, is not very convenient for cleaning.
WO 99/10024 describes a portable pumping module for thoracic drainage, which is connected via an external line to a portable oval-curved secretion collecting container. The disadvantages of this device are the need to wear two separate modules, as well as the fact that they are connected by means of a flexible hose.
Further, in EP 1184043 A, a small-sized aspiration pump is described, mainly for wound drainage, which has a collecting container for the aspirated material and a lid. Moreover, all the components of the pump necessary for its operation are integrated in the lid of the tank.
In connection with the foregoing, one of the problems to which the invention is directed is to create a portable aspiration module for aspiration of body fluids, which provides the patient with the maximum possible mobility and which is convenient to maintain.
This problem is solved by the creation of a portable aspiration (drainage) module in accordance with claim 1.
A portable aspiration module for aspirating body fluids and / or air comprises a pumping unit housing with a pumping unit and at least one collecting container for receiving fluid, detachably attached to said housing, said housing having a front wall , a back wall and a side wall located between said walls. Each of the front and rear walls has an edge protruding beyond the specified side wall, and the collecting container is held between these edges and is pivotally rotated in the direction from these edges and towards them. In this embodiment, the collecting container can easily be attached to the housing of the pump unit and securely fixed to it, being protected, since it does not protrude from the housing.
The patient may wear an aspiration module that can be attached in various ways. It can be hung around the neck using a suitable belt, attached to a belt or worn on a belt over your shoulder. A lying patient can put the module on a table or simply hang it on a bed.
At the same time, collecting containers of various sizes can be used with the same housing. This reduces production and operating costs.
In one preferred embodiment, the collecting container is held between the edges of the front and rear walls and pivotally connected to them by its lower part. At the same time, it can be fixed on the body with its upper part.
It is advisable to make the collecting container completely detachable from the housing. Replacing this container is easier if it is snapped onto the housing.
The aspiration module of the invention is used for medical purposes, especially for thoracic drainage and for drainage of wounds. However, other applications are possible, for example, for aspiration of body fluids during surgery or for liposuction.
It is advisable, especially in the case of thoracic drainage and drainage of wounds, to use the module in continuous operation to actively maintain a constant level of vacuum (vacuum). This will not only accelerate recovery, but also reduce operating costs, since the device will be used for a shorter period, i.e. the duration of its lease will be less than for similar known devices.
In one of the embodiments of the invention, the module contains a locking protrusion, which is released by means of the unlocking element from the interaction, which secures the collecting container.
In a preferred embodiment, the collecting container may be snapped onto the bottom of the housing.
In another preferred embodiment, the collecting container is provided with protruding spikes, and transverse guides in the form of cutouts are made in the housing, while the possibility of interaction between the spikes and the guides is provided.
In a preferred embodiment, the housing has a supporting surface for mounting the module on various surfaces, with the bottom of the collecting container located above said supporting surface.
In another embodiment, the specified housing is configured, in essence, in the form of a cuboid.
In a preferred embodiment, the pump unit comprises at least an electric motor and a vacuum pump, which is a diaphragm pump, the pump unit being installed in the central part of the housing.
In one embodiment, the collecting container extends beyond the housing on one side only.
In one embodiment, the connector for the tube leading to the patient is located in the front wall of the housing.
In one embodiment, the vacuum connector and the secret connector are located in the side wall of the housing.
In one embodiment, the module comprises an adapter for a tube leading to a patient, configured to be inserted into a wall of the housing for connection to a pump unit and a collecting container.
In one embodiment, the connector or adapter is configured to connect to a double-lumen tube supplied to a patient and consisting of a secret line and a control line.
Another objective solved by the invention is the development of a collecting container for receiving liquid, which can be used, first of all, in aspiration modules of the described type and which prevents contamination of the suction (drainage) line or suction pump by the suction liquid.
This problem is solved by creating a collecting container for a liquid having the features included in paragraph 14 of the claims.
The collecting container according to the invention comprises a connector for connecting a secret line to the patient, and a vacuum connector for connecting to a vacuum pump. The interior of the collecting container is divided by ribs into at least a vacuum chamber and a secret chamber. These cameras are connected to each other via at least one narrow channel. In this case, the vacuum connector and the secret connector are located respectively in the vacuum chamber and in the secret chamber.
It is advisable to make a vacuum chamber and a secret chamber without direct communication with one another, placing an intermediate chamber between them for this purpose. In the upper part of the secret chamber, under the vacuum chamber, it is desirable to install an inclined rib, which prevents the liquid from rising upward.
The separation of the vacuum chamber and the secret chamber provides relatively reliable protection for the vacuum connector even without the use of check valves or membranes.
Further effective embodiments are disclosed in the dependent claims.
In one embodiment, an intermediate chamber is located between the vacuum chamber and the secret chamber, the vacuum channel passing from the vacuum chamber to the intermediate chamber, and the intermediate channel passing from the intermediate chamber to the secret chamber.
In one embodiment, the implementation of the vacuum chamber and the secret chamber are made without direct communication with one another.
In another embodiment, the vacuum chamber is located in the upper region of the collecting container.
Preferably, in the upper part of the secret chamber, adjacent to the vacuum chamber, there is an inclined rib located throughout the entire depth of the container and over a significant portion of the width, but not across the entire width of the container.
In one embodiment, the secret chamber is divided by vertical ribs into subchambers communicating with one another.
Another aspect of the present invention provides a portable aspiration module for aspirating body fluids and / or air, comprising a pump unit housing with a pump unit and at least one collecting container for receiving liquid attached, with the possibility of separation, to the specified body, while the housing has a front wall, a rear wall and a side wall located between the walls, characterized in that it contains an adapter for a tube leading to the patient, made with the possibility of input into Tenk of the case and connections to the collecting tank.
Another aspect of the present invention provides a portable aspiration module for aspirating body fluids and / or air, comprising a housing of a pump unit with a pump unit and at least one collecting container for receiving fluid, attached, with the possibility of separation, to the specified body, while said housing has a front wall, a rear wall and a side wall located between said walls, characterized in that a vacuum connector and a secret connector are arranged in the side wall of the housing.
In a preferred embodiment, a connector for a tube leading to the patient is located in the front wall of the housing.

Figure 11 in a perspective image shows the first part of the collecting tank of figure 10.
On Fig in a perspective image shows the second part of the collecting capacity of figure 10.
1 and 2 show a first embodiment of an aspiration module according to the invention. It consists essentially of a housing 1 of the pump unit with a pump unit 6 installed inside it (shown in FIG. 2) and at least one collecting tank 2. It is preferable to use just one collecting tank 2. The pump unit 6 is used to create partial vacuum (vacuum) necessary for the implementation of aspiration. The collecting tank 2 can be connected to the pump unit 6, so that a vacuum can be created in it. The collecting container 2 is connected by means of an aspiration tube (secret line) 30 to a cavity in the patient’s body or to a wound, from which it is required to drain the body fluid that accumulates in the collecting container 2.
It is preferable to bring to the patient’s body not only the secret line 30, but also the control line 31, with which, for example, the pressure or the amount of fluid flowing along the secret line 30 can be measured. For this purpose, a double-lumen tube 3 is preferably used, leading to the patient and forming both lines 30, 31. As shown in the drawings, this tube 3 can depart from the housing 1 in a straight line. However, you can give it a bend or use a curved adapter into which the tube 3 is inserted.
The specified tube 3 is preferably mounted on the adapter 7, which is shown in the detailed image in Fig.7. Preferably, it is made of plastic by injection molding. He has a connector 71 for a double-lumen tube, on which or into which a double-lumen tube 3 can be installed, which is supplied to the patient. A flange 70 is made on this connector 71, which is adjacent to the housing 1 and through which the adapter 7 can be mounted on the housing 1, for example, using fasteners. The adapter portion 7 located inside the housing is provided with a curved connecting part 72 for attaching a secret connector 19 to the housing and a connecting part 73 for attaching a control line 31 or control lines. The end face of the adapter, opposite the connecting part 72, is blocked by a plug 74.
The main parts of the pump unit 6 are an electric motor 60, a secondary battery or batteries 61, and a vacuum pump 62. The electric motor 60 is preferably flanged to a vacuum pump 62, which is preferably mounted on the housing 1. Any known pumps of sufficiently small sizes, but powerful enough for related applications. The pump capacity is preferably 5 l / min. A double acting diaphragm pump is preferred.
The pump unit 6 is preferably located in the middle (central) part of the housing 1. It is desirable to position the pump unit 6 so that the position of the common center of gravity of the housing 1 and the pump unit 6 prevents the housing 1 from tilting when the patient carries it.
The housing 1 of the pump unit is preferably made of plastic or metal, and it is configured essentially in the form of a cuboid with a rear wall 10, a front wall 11 approximately parallel to the rear wall, a first side wall 16 located between these walls, a second side wall 17, approximately parallel to the first side wall 16, as well as the upper wall 12 and the lower wall (not visible in FIG. 1). The rear wall 10 and the front wall 11 can be made flat. However, as can be seen in FIG. 3, the front wall 11 may have a central outer protrusion 112. The rear wall 10 may be bent inward so as to conform to the shape of the human body and therefore fit better against it. The front wall 11 may also have a corresponding bend.
It is desirable that the rear and front walls 10, 11 have the largest surface. In addition, the upper wall 12 and the lower wall are made longer than the side walls 16, 17, so that the housing 1 has the shape of a horizontal cuboid.
The drawings do not show the fastening means for the respective clamps and belts used to carry the portable suction module. These means are preferably located on the rear wall or on the side walls of the housing.
The functional components of the pump unit 6 are located in its housing 1. These elements are preferably located in the upper wall 12. In the presented example, there is a main starter 5, which serves to turn on / off the suction module. In addition, there is a display 15 with an active field, which displays the status of the module, the progress of the aspiration process and other information useful for optimizing aspiration. For example, a measured air flow through a secret line 30 may be displayed in the display field 15. In addition, a component for storing data can be placed in the housing 1 for storing the measurement results and for displaying these results on the display 15 when an appropriate command is entered through its active field.
Using the active field of the display 15, it is also possible to activate a vacuum pump 62 or an electric motor 60, as well as set or select the desired parameters of the suction process. It is desirable that the active field of the display 15 is a touch screen of a known type. However, instead of such a screen, you can use the function buttons and switches or a regular LCD display. Moreover, such elements can be embedded in various walls. The rear and front walls 10, 11 protrude at their edges, at least for the first side wall and, preferably, for the second side wall, as well as for the upper and lower walls. These protruding edges of the walls 10, 11 prevent the display 15 from being turned on inadvertently.
The collecting tank 2 also has an approximately cuboid shape. It has two approximately parallel to each other flat walls 22, forming the front and rear walls. This also applies to the side walls, as well as the upper and lower walls.
The collecting tank 2 is attached to the housing 1 with the possibility of detachment and separation from it. For this, the sections of the rear wall 10 and the front wall 11 of the housing respectively have edges 110 and 100, which protrude beyond the first side wall 16. These edges 100, 110 of the walls 10, 11 are preferably made curved, with recesses in the direction of the surface of the corresponding walls. A collecting container 2 is located between these edges 100, 110, and their curved sections facilitate gripping and holding this container 2 by the user.
As can be seen from FIGS. 3 and 4, the collecting container is capable of articulating rotation in the direction from the housing and towards it in the space between the edges 100, 110. To enable such rotation (tilt), it is fixed in its lower part between the edges 100, 110 It is desirable that it can be installed in a fixed position quickly and with a snap. To do this, on the front and rear walls 22 of the collecting tank 2 there are corresponding bolts, and in the edges 100, 110 there are corresponding sockets. Of course, it is also possible to install bolts in the edges 100, 110, and the sockets can be made in a collecting container 2. In addition, other types of fastening are possible, allowing you to tilt and then separate the collecting container 2. At least in this area, the shape of the front and the rear walls 22 of the collecting container 2 corresponds to the shape of the edges 100, 110.
The collecting tank 2 can be fixed relative to the housing 1 with its upper part. To do this, a groove 20 is made in the collecting container 2, which includes the corresponding locking protrusion 14 of the housing 1. The locking protrusion 14 can be removed from the groove 20 by pressing the unlocking button 13, which allows the collecting container 2 to be tilted outward. The unlocking button 13 is preferably located in the upper wall 12 of the housing. As additional supports of the collecting tank 2, additional spikes can be provided on its front and rear walls, which are pressed against the edges 100, 110, preventing the collecting tank 2 from moving away from the housing 1 after unlocking.
To connect the housing 1 or the pump unit 6 to the collecting tank 2 in the housing 1 there is a vacuum connector 18 and a connector 19 for a secret, shown in figure 3. The corresponding connectors on the collecting tank can be seen in figure 4. The vacuum connector on the collecting container is designated as 24, and the secret connector as 25. Both connectors are located on the side wall 23 of the collecting container 2. Vacuum connectors 24, 18 are used to connect the vacuum pump 62 to the collecting container 2. Connectors 19, 25 for secret the collecting container 2 is connected to an adapter 7, which can be connected to the secret line 30.
When separating the collecting container 2, the secret connector 25 from the side of the collecting container can be closed by means of a closure element 4, preferably fixed to the collecting container 2 (as can be seen in FIG. 4) and consisting of a rod and a stopper located at the end of the rod. The plug may overlap the connector 25. The vacuum connector 24 may be blocked by a filter (not shown), which automatically closes when fully saturated with moisture. There are other options for overlapping connectors.
From figure 2 it is seen that the protruding edges of the housing 1 of the pump unit, namely the lower rear and front edges 101, 111, form a supporting surface for mounting the housing on any surface, such as a table. However, the lower wall (bottom) of the collecting container 2 is preferably located above the level of this abutment surface, so that this container is suspended from the housing 1. However, as can be seen from figure 5, it is located between the two edges 100, 110 and is held by them. In addition, it can be seen that the collecting container 2 protrudes beyond the housing 1, preferably on only one side.
The dimensions of the collecting vessel 2 may vary. Figures 5 and 6 show variants of a relatively short and relatively long collecting container 2, respectively. They should only have the same shape in the area between the edges 100, 110, so that they can be attached to the same housing 1. The remaining parameters of their profiles are arbitrary.
Figs. 8 and 9 illustrate two opposing parts of the housing 1 of the pump unit in the third embodiment of the invention. These two parts form the back wall 10 (Fig. 8) and the front wall 11 (Fig. 9) of the housing 1. It is advisable to form each such part by injection molding in the form of an integral plastic part.
Both parts 10, 11 are designed in such a way that they can be inserted one into the other in the presence of a gap between them. For this purpose, the parts 10, 11 are provided on their inner sides with pins 113 protruding in the perpendicular direction and opposing receiving sleeves 114. These pins 113 and the sleeves 114 are preferably also injection-molded, in conjunction with parts 10, 11.
One or both of these two walls, for example, the rear wall 10, can be provided with a handle 12 ', in which a groove 120 is open at the top. This groove 120 is used to place therein or to fix on it a tube 3 leading to the patient, which is suitable to the suction module through handle 12 '.
At least one of the parts 10, 11 (preferably both parts) is provided with (provided) on the lower and upper sides of the upper and lower guides 115, 116, respectively, in the form of curly cuts. Two opposite upper guides 115 have an expanded entrance zone and an adjacent horizontal end section extending from the edge of the corresponding part inward. The two opposing lower rails 116 likewise have an expanded entry area. This zone, however, goes into an end section extending obliquely down and inward from the edge. These guides 115 and 116 serve to fix and hold the collecting container 2.
A corresponding collecting container 2 made of plastic is shown in FIG. 10. In the area of its side wall 23, the collecting container 2 is provided with upper and lower spikes (protrusions) 21, 21 ', respectively, which are injection molded at the same time with its rear or front wall, respectively, and are oriented perpendicular to it.
In order to detach the collecting container 2 in a detachable manner to the housing 1, first lower spikes 21 'are inserted into the lower guides 11 as far as it will go. Then, by turning the collecting container 2 around the axis formed by the spikes 21' in their final position in the lower guides, they are inserted with a snap the upper spikes 21 in the upper guides 115, thereby setting the collecting tank 2 in its final position. The same type of fastening is preferably used for the options described below. Spikes can also be formed on the housing, and guides in the form of slots on the collecting container. Other mounts are possible.
As can be seen from FIG. 10, with respect to this collecting container 2, the vacuum connector 24 and the secret connector 25 on the collecting container have a design different from the previous embodiment. The adapter 70 also does not need to be located on the front or rear wall 11, 10, it can be located on another section of the housing 1, for example, on its end side. In addition, instead of the groove 20, the collecting container 2 is provided with a latch 23 'for fixing it to the housing 1, which has a latching element interacting with the latch 23'. The fixing means located on the collecting container and the housing can be interchanged and combined in any convenient manner. These agents can also be used in the options discussed below.
The collecting vessel 2 may have a single chamber. However, it is desirable to separate the interior of the collecting vessel 2, as shown in FIGS. 11 and 12. Such a collecting vessel can be used in all variants of the module under consideration.
The collecting container 2 consists of two parts 2 ', 2 "made of plastic by injection molding and connected with the formation of the collecting container. The parts 2', 2" are preferably transparent, and they can be connected mechanically and, if necessary, melted one to the other. In the interior of both parts 2 ', 2 "there are various ribs (partitions), which will be described in detail below. Moreover, the ribs of both parts 2', 2" are congruent, so that when the parts 2 ', 2 "are connected together, they form chambers and compartments: During assembly, the ribs are preferably fused or glued to one another to provide a tight (i.e. impermeable to air and liquid) connection.
The vacuum connector 24 is installed in the upper part of the collecting container 2, preferably in its side wall 23, which is provided with spikes 21, 21 'for fastening with a snap into the housing 1. The specified connector 24 is made in the form of a through hole in the side wall 23 leading to the vacuum chamber 26, 26 ', which, with the exception of the vacuum channel 261, is sealed and completely separated from the rest of the internal volume of the collecting vessel 2. This channel is formed by a first curved rib 260 located in the first part 2' and a second rib 260 ', which it has the same shape as the first rib 260, and is located in the second part 2 ". The vacuum channel 261 may be in the first part 2 ', or, as shown in Fig. 12, in the second part 2", or in the area of the two ribs 260, 260 '. This channel 261 is preferably located in the upper region adjacent to the upper wall of the collecting vessel 2.
Adjacent to the vacuum chamber 26, 26 ', also adjacent to the upper wall, is an intermediate chamber 27, 27'. A vacuum channel 261 connects the vacuum chamber 26, 26 ′ to the intermediate chamber 27, 27 ′. The intermediate chamber 27, 27 'is preferably formed by a third rib 270, which is curved at right angles and located in the first part 2', and a fourth rib 270 'congruent to it in the second part 2 ". A channel 271 is formed in one of the two parts or in the intermediate region (referred to as an intermediate passage) that connects the intermediate chamber 27, 27 ′ to the remaining internal volume of the collecting vessel 2. The intermediate channel 271 is preferably located in an area remote from the vacuum chamber 26, 26 ′.
Both channels 261, 271 are made quite narrow. However, it is possible to form several such channels. These channels should be small enough to prevent, as far as possible, the occurrence of a backflow of secretion or other aspirated liquid, but at the same time large enough so that the collecting container can begin to function as soon as possible after applying vacuum to it.
Below the intermediate chamber 27, 27 'and below the intermediate channel 271 in parts 2', 2 "there is one inclined rib 28, 28 ', each of which is directed downward from the intermediate channel 271 in the direction of the vacuum chamber 26, 26'. Inclined ribs 28 , 28 'divide the inner space of the collecting container into upper and lower regions, the upper region having a much smaller volume than the lower one. The inclined ribs 28, 28' overlap in width a significant part of the collecting container 2 (but not all of this container) and completely cover it in depth. During drainage, the drained fluids should drain down the inclined ribs 28, 28 '.
The lower region can be provided with vertical dividing ribs 290, 290 ′, 291. Long dividing ribs (for example, ribs 290, 290 ′) can cover almost the entire lower region in height, and short ones (for example, rib 291) can cover only a small part of it.
The secret connector 25 is located in the lower region. Due to this, the lower region serves to receive drained fluids, i.e. forms a chamber 29, 29 'for collecting secret. The dividing ribs 290, 290 ', 291 divide this chamber into sub-chambers that are hydraulically connected to one another. However, the presence of subcameras prevents the free movement of fluid back and forth. Inclined ribs 28, 28 'prevent liquid from spraying in the upper region of the vessel and prevent liquid from returning to this region if the collecting vessel is slightly inclined. The small inlet openings of the channels and especially the presence of the labyrinth structure formed by creating an intermediate chamber do not allow the liquid, which, nevertheless, penetrated into the upper region, to reach the vacuum connector.
In one (not illustrated) embodiment, the ribs are located in only one part of the collecting container, the second part of which is made flat and serves as a cover.
The intermediate chamber 27, 27 ′ is an optional but preferred part since it eliminates the direct connection between the vacuum chamber 26, 26 ′ and the secret chamber 29, 29 ′.
All described variants of the collecting container may have various sizes.
The aspiration module of the invention provides a simple and safe replacement of the collecting container and improves patient mobility.
