5. The lancet device of claim 2, wherein the back cap is coupled to in inner sleeve that includes a surface that engages the rear end of the holding member.
11. The lancet device of claim 9, wherein the first spring contacts one side of a projection extending inwardly from the body and wherein the second spring contacts another side of the projection.
29. The lancet device of claim 26, wherein the journal comprises a center axis that is generally perpendicular to the axis running through the holding member.
FIG. 5 shows another cross-section side view of the lancet device LD shown in FIG. 1 (the lancet 10 is not shown in cross-section). In FIG. 5, the back cap 80 is shown in the extended position. As described above, this movement is used to retract the holding member 30 until the deflecting member 30 c engages the shoulder 100 i of the upper body part 100. At this point, the user need only release the back cap 80 so that the third spring S3 will automatically cause the back cap 80 to move or retract towards the lancet device until it assumes the position shown in FIG. 1. As can be seen when comparing FIGS. 2 and 5, the first spring S1 becomes compressed axially when the back cap 80 causes the holding member 30 to move to a retracted position. As a result, the second spring S2 expands axially (see FIGS. 2 and 5), while the third spring S3 compresses axially (see FIG. 5). However, once the back cap 80 is released, the third spring S3 expands axially —which causes the back cap 80 (and the attached inner sleeve 70) to retract back into the lancet device (see FIG. 1).
The upper body part 100 additionally preferably includes two plate-like projections 100 h which are generally centrally disposed relative to sides 100 c and 100 d. The purpose of these projections 100 h is to help guide the deflecting member 30 c of the lancet holder 30 along a linear path. These projections 00 h may also prevent the holding member 30 from rotating within the lancet device. In this regard, the projections 100 h are spaced apart a distance that is slightly greater than a width of deflecting member 30 c (see FIG. 15A). By ensuring that the projections 100 h are spaced apart by an amount that is greater than a width of the deflecting member 30 c, the holding member 30 can be allowed to move forward and backwards with the lancet device without rotating. Two C-shaped projections 100 j also extend inwardly from the wall of the upper body part 100. These projections 100 j form an upper half portion of a bearing system for the trigger 40. Together with the lower projections 110 g (see FIG. 8), i.e., lower half portion of the bearing system, the parts 100 j and 100 g form two circular bearing supports for the trigger 40. As will be described later on with regard to FIG. 14, the journal elements 40 c of the trigger 40 are mounted to the bearing supports 100 j/110 g. The upper body part 100 additionally preferably includes a connecting rib 100 k that provides strength to the upper body part 100. In order to allow the holding member 30 move freely within the lancet device and without being obstructed by the rib 100 k, a circular or curved recess (see FIG. 7D) is formed in the center of the rib 100 k. This recess of the rib 100 k can have a radius of approximately 0.15″.
The upper body part 100 also includes circular or curved indented and/or recessed side portions 100 e and 100 f. These recesses 100 e and 100 f may have a radius of approximately 0.66″. As described previously, these recessed portions allow a user to access the cam disk 60. That way, the user can use a finger to rotate the cam disk 60 from either side 100 c or side 100 d. As seen in FIG. 7D, the sides 100 c and 100 d can be curved outwardly (i.e., convex) and have a radius of approximately 0.6″. The sides 100 c and 100 d can also preferably be curved outwardly in the length direction (i.e., see FIG. 7A) and have a radius of approximately 16.8″. The rear edge 100 b of the upper body part 100 is a continuous straight edge that is configured to make contact with shoulder 80 p of back cap 80 (see FIG. 10).
The lower body part 110 also preferably has a curved bottom surface 1101. This surface 1101 extends from the rear edge 110 b to the shoulder 110 a 1 and may have a radius of approximately 31″ and/or may be essentially straight. The lower body part 110 additionally preferably includes two plate-like projections 100 m which are generally centrally disposed relative to sides 110 c and 110 d. The purpose of these projections 110 m is to help guide the holding member 30 along a generally linear path. In this regard, the projections 110 m are spaced apart a distance similar to projections 100 h described with respect to FIG. 7. Two c-shaped projections 110 g also extend upwardly from the wall of the lower body 110. A connecting rib 110 n serves to connect the projections 110 g to the bottom wall 1101 and sides 110 c and 110 d. These projections 110 g form a lower half of a bearing system for the trigger 40. Together with the upper projections 100 j (see FIG. 7), i.e., upper half of the bearing system, the parts 100 j and 110 g form two circular bearing supports for the trigger 40. As will be described later on with regard to FIG. 14, the journal elements 40 c of the trigger 40 are mounted to the bearing supports formed by parts 100 j/110 g. The lower body part 110 additionally includes connecting ribs 110 i and 110 k that provides strength to the lower body part 110. In order to allow the holding member 30 move freely within the lancet device and without being obstructed by the ribs 110 i and 110 k, circular or curved recesses (see FIG. 8D) are formed in the center of the ribs 110 i and 110 k. These recesses of the ribs 110 i and 110 k can have a radius of approximately 0.15″.
The lower body part 110 further preferably includes a rectangular shaped projection 110 h that is generally centrally disposed relative to sides 110 c and 110 d. The purpose of this projection 110 h is to guide the holding member 30 within the lancet device and to serve as stops for springs S1 and S2. The projection 110 h has a polygonal (i.e., four sided) shaped outer surface. A left side surface of the projection 110 h serves a contact surface for spring S2 (see e.g., FIG. 1.). A right side surface of the projection 110 h serves a contact surface for spring S1 (see e.g., FIG. 1). The projection 110 h also has an inner recess that includes an inner tapered or conical portion and a rounded bottom end. This is so mainly for ease of manufacture and to reduce material costs. As can be seen from FIG. 1, the length of the projection 110 h should not be so great so as to contact the cam disk 60. However, it should be of sufficient length so as to project through and slightly beyond the holding member 30.
Side wall 20 a is preferably tapered inwardly from edge 20 h to surface 20 e and formes a rounded corner (e.g., with a radius of approximately 0.1″) where wall 20 a meets wall 20 e. This wall 20 a can be curved along its length (see FIG. 9B), having a radius of approximately 33.5″, may also be curved outwardly (i.e., convex, see FIG. 9E) and may be formed by two curved surfaces. One curved surface may have a radius of approximately 1″ and may extend from wall 20 c towards wall 20 d. Another curved surface may have a radius of approximately 1″ and may extend from wall 20 d towards wall 20 c. These two surfaces may meet generally at the center of wall 20 a. Side wall 20 b is tapered inwardly from edge 20 h to surface 20 e and formed a rounded corner (e.g., with a radius of approximately 0.1″) where wall 20 b meets wall 20 e. This wall 20 b can be curved along its length (see FIG. 9B), having a radius of approximately 33.5″, may also be curve outwardly (i.e., convex, see FIG. 9E) and may be formed by two curved surfaces. One curved surface may have a radius of approximately 1″ and may extend from wall 20 c towards wall 20 d. Another curved surface may have a radius of approximately 1 and may extend from wall 20 d towards wall 20 c. These two surfaces may meet generally at the center of wall 20 b. Side wall 20 c is tapered inwardly from edge 20 h to surface 20 e and formed a rounded corner (e.g., with a radius of approximately 0.1″) where wall 20 c meets wall 20 e. This wall 20 c can be curved along its length (see FIG. 9D), having a radius of approximately 22″, may also be curved outwardly (i.e., convex, see FIG. 9E), may be formed by one curved surface that has a radius of approximately 1.8″ and may extend from wall 20 a towards wall 20 b. Side wall 20 d is tapered inwardly from edge 20 h to surface 20 e and formed a rounded corner (e.g., with a radius of approximately 0.1″) where wall 20 d meets wall 20 e. This wall 20 d can be curved along its length (see FIG. 9D), having a radius of approximately 62″ and may also be curved outwardly (i.e., convex, see FIG. 9E), may be formed by one curved surface that has a radius of approximately 1.9″ and may extend from wall 20 a towards wall 20 b. The inner surface of wall 20 e can be planar (see FIG. 9A).
The side walls 80 b-80 e also preferably taper slightly from shoulder 80 p to edge 80 a by approximately 0.5 degrees (per side). The width of the rectangular edge at the bottom of the shoulder 80 p (measured up and down in FIG. 10C) may be approximately 0.51″ while the width of this edge (measured up and down in FIG. 10F) may be approximately 0.54″. The width of the rectangular edge at the top of the shoulder 80 p (measured up and down in FIG. 10C) may be approximately 0.6″ while the width of this edge (measured up and down in FIG. 10F) may be approximately 0.61″. Side walls 80 f, 80 g, 80 h and 80 i also taper slightly from the top of shoulder 80 p to surface 80 k. The approximately square shaped surface 80 k has a length and width of approximately 0.5∝. However, the walls 80 f, 80 g, 80 h and 80 i may also be curved outwards slightly. In this regard, wall 80 h may have a radius of approximately 108.3″ (measured in the direction of the length shown in FIG. 10B) and may be outwardly curved with a radius of approximately 1″ (see FIG. 10A). Wall 80 i may have a radius of approximately 31″ (measured in the direction of the length shown in FIG. 10B) and may be outwardly curved with a radius of approximately 1″ (see FIG. 10A). Wall 80 f may have a radius of approximately 16.7″ (measured in the direction of the length shown in FIG. 10E) and may be outwardly curved by being formed by two curved surfaces each having a radius of approximately 0.5″ and each extending from sides 80 h and 80 i (see FIG. 10A). Wall 80 g may have a radius of approximately 16.7″ (measured in the direction of the length shown in FIG. 10E) and may be outwardly curved by being formed by two curved surfaces each having a radius of approximately 0.5″ and each extending from sides 80 h and 80 i (see FIG. 10A).
Opening 70 n preferably tapers outwardly from surface 70 p towards edge 70 b at an angle of approximately 0.5 degrees (per side). The width of the rectangular inner surface 70 p (measured up and down in FIG. 11E) may be approximately 0.40″ while the width of the same surface (measured up and down in FIG. 11A) may be approximately 0.43″. The walls 70 c, 70 d, 70 e and 70 f are configured to slide into opening 801 until shoulder 70 g contacts edge 80 a of back cap 80 and until projection 70 h engages recess 80 m of back cap 80. The projection 70 h is a continuous projection and may have a radius of approximately 0.007″ and may extend inwardly approximately 0.004″. As was explained with regard to FIG. 10, this projection 70 h is configured to fit into or otherwise engage with the continuous recess 80 m of back cap 80 (see FIGS. 10C and 10D). Of course, the projection 70 h need not be continuous, i.e., it does not have to extend continuously. It can instead be formed with intermitted projections or it may have the form of a single short projection on at least two opposite sides and that are centrally arranged with respect to walls 70 c-70 f. Of course, other connecting mechanisms, whether conventional or otherwise, may also be utilized in place of the projection and recess connection.
The side walls 70 c-70 f also preferably taper slightly from shoulder 70 g to edge 70 b by approximately 0.5 degrees (per side). The width of the rectangular edge at the bottom of the shoulder 70 g (measured up and down in FIG. 11A) may be approximately 0.49″ while the width of this edge (measured up and down in FIG. 1E) may be approximately 0.46″. The distance between the shoulder 70 g (measured across FIG. 11A) to surface 70 a may be approximately 0.04″. Side walls 70 c, 70 d, 70 e and 70 f also taper slightly from the bottom of surface 70 p to edge 70 b. The walls 70 c-70 f may also be curved outwards slightly (See FIG. 11D). In this regard, wall 70 c may have a radius of approximately 0.95″ (measured in the direction of FIG. 1I D). Wall 70 d may have a radius of approximately 0.9″ (measured in the direction of FIG. 11D). Wall 70 e may have a radius of approximately 0.43″ (measured in the direction of FIG. 11D). Wall 70 f may have a radius of approximately 0.43″ (measured in the direction of FIG. 11D).
The retaining element 50 preferably has a front planar wall 50 d and a rear planar wall 50 c. A centrally disposed projection 50 b extends from surface 50 d. The projection 50 b tapers inwardly from surface 50 d to end 50 e. The distance between end 50 e to surface 50 d can be approximately 0.8″. The diameter of the projection 50 b can be approximately 0.67″ at surface 50 d and can taper towards end 50 e by approximately 1″ (per side). The diameter of surface 50 a can be approximately 0.25″ and may similarly be tapered from side 50 c to side 50 d by approximately 1 degree (per side). End 50 e can also have a chamfer that is approximately 0.02″×0.02″.
FIGS. 14A-C show top, side and front views of the trigger 40. The trigger 40 can preferably be made as one-piece structure by e.g., injection molding. In this regard, it is preferably made of a plastic or synthetic resin such as, e.g., ABS plastic. The trigger 40 may also have be made of ABS —Red and have a finish designated as SPI-A2. Additionally, the trigger 40 may have an overall length that is approximately 0.9″ (i.e., between edges 40 j and 40 i). Of course, other materials and/or finishes may be utilized, without leaving the scope of the invention. Moreover, the trigger 40 may even be made of a plurality of sections of parts which are joined together to form the complete trigger 40, without leaving the scope of the invention.
The trigger 40 preferably has a end 40 j that includes a rounded projection 40 e. This rounded projection 40 e is configured to contact an inner surface of upper body part 100 (see FIG. 1) and serves to brace or counter the movement of the trigger 40 when the trigger 40 is pressed into the lancet device. The projection 40 e may have a radius of approximately 0.03″. The trigger 40 also has end 40 i that includes a rounded projection 40 g. This rounded projection 40 g is configured to contact surface 30 c 3 of deflecting member 30 c of the holding member 30 (see FIG. 15) upon movement of the trigger 40, when the trigger 40 is pressed into the lancet device. The projection 40 g may have a radius of approximately 0.03″. The trigger 40 also includes a connecting member 40 f which connects the push button 40 a to the support 40 d. Two shaft members or journals 40 c project from opposite sides of the support 40 d. The journals 40 c may have a diameter of approximately 0.06″ and may project approximately 0.16″ from support 40 d. These journals 40 c also have rounded ends whose radius can be approximately 0.03″. As explained previously, these journals 40 c are configured to be mounted in the bearing supports formed by parts 100 j and 110 g. In this regard, the openings formed by these parts 100 j and 110 g should be sized to be the same or slightly larger than the diameter of journals 40 c. In this way, the journals 40 c can fit snugly in the supports 100 j/l10 g. The width (measured in the direction of FIG. 14A) of the support 40 d may be approximately 0.1″.
FIGS. 15A-E show top, side cross-section and front views of the holding member 30. The holding member 30 can preferably be made as one-piece structure by e.g., injection molding. In this regard, it is preferably made of a plastic or synthetic resin such as, e.g.; Delrin plastic. The holding member 30 may also have be made of Delrin—Natural and have a finish designated as SPI-C1. Additionally, the holding member 30 may have an overall length that is approximately 2.8″ (i.e., between edges 30 a and 30 d). Of course, other materials and/or finishes may be utilized, without leaving the scope of the invention. Moreover, the holding member 30 may even be made of a plurality of sections of parts which are joined together to form the complete holding member 30, without leaving the scope of the invention.
In this regard, the distance between surface 60 e 8 and the center axis of cam disk 60 can be approximately 0.16″, the distance between surface 60 e 7 and the axis of cam disk 60 can be approximately 0.169″, the distance between surface 60 e 6 and the axis of cam disk 60 can be approximately 0.178″, the distance between surface 60 e 5 and the axis of cam disk 60 can be approximately 0.187″, the distance between surface 60 e 4 and the axis of cam disk 60 can be approximately 0.196″, the distance between surface 60 e 3 and the axis of cam disk 60 can be approximately 0.205″, the distance between surface 60 e 2 and the axis of cam disk 60 can be approximately 0.214″, and the distance between surface 60 e 1 and the axis of cam disk 60 can be approximately 0.223″. The surfaces 60 e 1-60 e 8 are separated by rounded projections which may have a radius of approximately 0.04″. The width of the surfaces 60 e 1-60 e 8 can be approximately 0.08″. The thickness of the cam section 60 can be approximately 0.05″ measured from surface 60 c and 60 d while the thickness of the indicia section can be approximately 0.08″ measured from surface 60 g and surface 60 c. Finally, the cam disk 60 preferably includes two indentations 60 h which are sized and configured to receive rounded tips of the two projections 10 j of the lower body part. These recesses can have depth of approximately 0.033″ and a rounded bottom whose radius is approximately 0.02″, and they may be spaced apart by approximately ⅝″. The cam disk 60 may also include a knurl, a high-friction surface, or other desired texturing (e.g., projections and recesses) along its peripheral edge (not shown).
