Definitions
- the invention relates to a lancet device which is easier, more economical and which is more efficient to make.
- the invention also relates to a lancet device preferably having an adjusting capability, and a method of using a lancet device.
- the invention relates to a lancet device which utilizes an adjustable depth penetration. Lancet devices are used to penetrate and puncture the skin in order to allow the taking of a blood sample for testing. The present device allows the user to control the depth of this penetration by a simple adjustment mechanism.
- Lancet devices are commonly used to prick the skin of the user so that one or more drops of blood may be extracted for testing.
- Some users such as diabetics, for example, may have to test their blood sugar levels several times a day. This may be accomplished by the user using a simple needle. However, this procedure is often problematic for the user since the needle may be difficult to handle. Moreover, controlling the depth of penetration cannot be reliably accomplished without the use of a mechanical device. Additionally, many users simply cannot perform the procedure owing to either a fear of needles or because they lack a steady hand. As a result, lancet devices have been developed which allow the user to more easily and reliably perform this procedure.
- the lancet device has a body portion which encloses a lancet and a lancet firing mechanism.
- the lancet typically has a needle extending therefrom and is caused to move towards the tip of the device by a trigger or firing mechanism.
- the lancet device forces the needle, by virtue of the needle being fixed thereto, out of the device by some distance or depth so that the needle can penetrate the skin of the user.
- the function of this firing mechanism and the lancet body design is disclosed in each of 5,797,942 and 5,908,434.
- the invention also provides a method of puncturing a surface of skin using the lancet device described above, wherein the method comprises adjusting a set depth of penetration of the needle by moving the front cover to a desired set position, disposing the skin engaging end of the lancet device against a user's skin, and triggering the trigger to cause the lancet needle to penetrate the user's skin, wherein the puncture allows a blood sample to be taken.
- FIG. 46 shows a partial section view of the embodiment shown in Fig. 1 rotated 90 degrees. The attachment of the spring to the front portion and body is shown;
- Figure 47 shows a rear cross-section view of the front cap shown in Fig. 48.
- the section view illustrates one possible configuration of the internal ratchet surface;
- Figure 48 shows a partial side cross-section view of one possible system for maintaining the depth setting of the front cap;
- Figure 49 shows a partial side cross-section view of the intermediate section shown in Fig.
- the spring 6 has one end, i.e., the left end, coupled to the front portion 4 of the holding member 4/5 and another end, i.e., the right end, coupled to the annular surface lb of the body 1.
- Fig. 46 One way this can occur is shown in Fig. 46, which will be more fully described later on.
- the spring 6 can, of course, be connected to these parts in any desired manner.
- the spring 6 can be connected to the front part and body in a manner similar to that of Fig. 45, i.e., via flanges formed on the parts 1 and 4. Using such an arrangement, the lancet needle only momentarily projects past the plane P in the extended position before it is caused to retract back in the lancet device by the spring 6.
- the holding member 4/5 has cylindrical outer surfaces (e.g., 4g and 5c) which slide within (with a clearance) cylindrical surfaces (e.g., 2d, la and Id) in the body 1 and intermediate section 2.
- cylindrical outer surfaces e.g., 4g and 5c
- cylindrical surfaces e.g., 2d, la and Id
- the holding member 4/5 can move towards the plane P until the stop surface MSS contacts or engages the stop surface FSS of the intermediate section 2.
- the needle of the lancet 10 projects past the plane P and through opening LO and thereby punctures the skin of a user which is resting against the plane P.
- the lancet device LD is then ready to be reloaded, i.e., it can then be placed back into the position shown in Fig. 3.
- Fig. 1 shows the lancet device LD in one of the pre-set extended positions, i.e., in one of the positions of the front cap 3 that will cause a desired puncture depth in the skin of a user (not shown).
- the distance that the lancet needle projects past plane P is thus determined by rotating the front cap 3 until the desired setting is reached, e.g., arrow 8 lines up with one of the indicia 7.
- the invention contemplates that any type of indicia can be used such as, e.g., numbers, letters, symbols, etc.
- the invention also contemplates that the body 1/2 can also contain the arrow while the indicia is placed on the front cap 3.
- the setting causes the plane P to move axially relative to fixed stop surface FSS. Since the movable stop surface MSS always contacts the fixed stop surface FSS in the extended position of the holding member 4/5, since the lancet 10 is secured to the front part 4, and since the plane P moves relative to the fixed stop surface FSS, adjustment of the front cap 3 (by rotation) causes a corresponding change in distance between plane P and the end of the lancet needle, e.g., the rotational position of the front cap 3 thus determines how much of the end of the lancet needle extends past the plane P.
- the depth setting is thus controlled by contact between the stop surface MSS, stop surface FSS, and the rotational position of the front cap 3.
- Fig. 4 shows the needle tip projecting through the opening LO in the front cover 3 and past the plane P. Thereafter, the user can pull end 5b back (from the position shown in Fig. 2) to compress spring 6 to again arm the lancet device LD.
- the front cap 103 has internal threads 103 c which engage external threads 102a of the intermediate section 102.
- the front cap 103 also includes chamfered corners 103b and raised projections 103a which allow a user to more securely grip the front cap 103.
- the intermediate body section 102 has an internal projecting wall 102b that includes a fixed stop surface FSS (see Fig. 11) which is configured to be engaged by a movable stop surface MSS (in particular stop surface MSS of front portion 104) that is formed on or coupled to the front portion 104 of holding member 104/105.
- FSS fixed stop surface
- MSS movable stop surface MSS of front portion 104
- the holding member 104/105 can also have a polygonal cross-section shape which corresponds to a polygonal opening in the body so as to ensure that the holding member 104/105 does not rotate while it moves axially back and forth.
- the holding member 104/105 has cylindrical outer surfaces (e.g., 104g and 105c) which slide within (with a clearance) cylindrical surfaces (e.g., 101a, 102d, and 10 Id) in the body 101 and intermediate section 102.
- cylindrical outer surfaces e.g., 104g and 105c
- cylindrical surfaces e.g., 101a, 102d, and 10 Id
- Fig.12 shows a cross-section view of the lancet device of Figs. 8-11 wherein the holding member 104/105 is in the fully extended position.
- the holding member 104/105 has reached its maximum extended position caused by axial expansion of the spring 106.
- the front cover 103, intermediate body 102, spring 106, lancet 10 and holding member 104/105 can be seen in their installed and/or assembled position.
- the spring 106 is arranged to surround the holding member 104/105, just behind the lancet receiving front portion 104.
- the spring 106 is preferably sized to slide into internal opening 101a of the body 101.
- This spring 206 causes (and/or biases) the holding member 204/205 to move towards an extended position (see Fig. 18) once the holding member 204/205 is pulled back (see Fig. 17).
- a user When a user wishes to place the lancet device LD in the loaded position, a user need only move gripping portion 205b rearwardly until the holding member arrangement 204/205 reaches the position shown in Fig. 17. This, in turn, compresses the spring 206 to a certain extent.
- spring 206 causes the holding member 204/205 to move to a fully extended position shown in Fig. 18.
- stop surface MSS and stop surface FSS see Fig.
- the front cap 203 is preferably mounted to the body 201 (and optionally to an intermediate section of the type shown in Fig. 2 if this embodiment is modified to include such an intermediate section) of the body 201 so as to be at least partially rotate in each of two directions.
- the front cap 203 can be mounted to the body 201 in any desired manner (i.e., with or without threads) provided it functions properly in the intended manner, i.e., provided it moves axially forwards and backwards.
- the front cap 203 has internal threads 203 c which engage external threads 201c of the body 201.
- FIG.18 shows a cross-section view of the lancet device of Figs. 14-17 wherein the holding member 204/205 is in the fully extended position. In this regard, the holding member 204/205 has reached its maximum extended position caused by axial expansion of the spring 206. As in Figs. 16 and 17, the front cover 203, spring 206, snap ring 202, lancet 10 and holding member 4/5 can be seen in their installed and/or assembled position. However, this figure allows one to more clearly see that the spring 206 is arranged to surround the holding member 204/205, just behind the lancet receiving front portion 204.
- a cylindrical opening 201a is sized to receive (with a clearance) the front portion 204 so that contact can occur between stop surface FSS and stop surface MSS.
- the stop surface FSS is an annular surface that is formed on an internal cylindrical wall of the snap ring 202 which is axially retained in recess 20 le.
- this wall can instead be formed by spaced projections which extend inwardly from the snap ring 202.
- the snap ring 202 can be replaced with a wall that is formed integrally with the body 201, as in the embodiment shown in, e.g., Fig. 1.
- the front part 204 includes a small cylindrical section 204a which utilizes two oppositely arranged slots 204d.
- LD has a lancet body 301 which can be made as a one-piece member as with the embodiment shown in, e.g., Figs. 1-7. Alternatively, it can be made as a two-piece structure as in the embodiment shown in, e.g., Fig. 39.
- body parts can, of course, be connected, e.g., using adhesives and/or fasteners and/or welding and/or snap-together holding mechanisms (not shown) to each other when the lancet device LD is initially assembled.
- a holding member 304/305 is movably disposed within the body 301.
- a front cover 303 is removably connected or attached to an intermediate section 302 of the body.
- the holding member 304/305 can also have a polygonal cross-section shape which corresponds to a polygonal opening 30 Id in the body 301 so as to ensure that the holding member 304/305 does not rotate while it moves axially back and forth.
- the holding member 304/305 has cylindrical outer surfaces (e.g., 304g and 305c) which slide within (with a clearance) cylindrical surfaces (e.g., 301a, 302d, and 301d) in the body 301 and intermediate section 302.
- the movable stop surface MSS always contacts the fixed stop surface FSS in the extended position of the holding member 304/305, and since the plane P moves relative to the fixed stop surface FSS, adjustment of the front cap 303 (by rotation) causes a corresponding change in distance between plane P and the end of the lancet needle, e.g., the rotational position of the front cap 303 thus determines how much of the end of the lancet needle extends past the plane P.
- the depth setting is thus controlled by contact between the stop surface MSS, stop surface FSS and the rotational position of the front cap 303.
- the needle tip can project through the opening LO in the front cover 303 and past the plane P.
- this wall 302b can instead be formed by spaced apart projections which extend inwardly from the section 302.
- this wall 302b can be formed as a separate part and/or removable part (e.g., a snap ring), as in the embodiment shown in Fig. 16.
- the front part 304 includes a small cylindrical section 304a which utilizes two oppositely arranged slots (see Fig. 26).
- the section 304a also has an internal opening (e.g., see 304f in Fig. 26) which is sized to receive the lancet 10.
- the front part 304 includes projections (e.g., see 304e in Fig.
- Front part 304 also includes larger cylindrical section 304g which can slide within openings 302d and 301a.
- the front part 304 also includes the deflecting member 304h which is formed integrally therewith.
- deflecting member 304h and the front part 304 are formed of a material which allows the deflecting member 304h to act as a spring in that it can be deflected inwards (compare Figs. 24 and 25) and thereafter return to an undeflected position (see Fig. 25).
- the lancet device LD defines a plane P which is configured to contact (i.e., be positioned against) a user's skin.
- the instant embodiment may utilize an inwardly curved and/or an outwardly curved surface plane P beyond which the lancet need can extend.
- the spring 406 causes (and/or biases) the holding member 404/405 to move towards an extended position (not shown) once the holding member 404/405 is pulled back (see Fig. 33) using the back cap 412.
- a user need only move the back cap 412 rearwardly until the holding member arrangement 404/405 reaches the position shown in Fig. 33.
- This compresses the first spring 406 to a certain extent and allows deflecting member 404h to catch or engage opening 40 lh.
- Such engagement ensures that the front portion 404 is prevented from moving axially towards the plane P until the trigger 409 is depressed.
- the second spring 415 is able to compress with a force that is far less that the force needed to compress spring 406.
- the spring 415 has a diameter of approximately 10.1 mm, a freelength of approximately 13.6 mm, and a wire size of 0.25 mm.
- the lancet needle only momentarily projects past the plane P in the extended position before it is caused to retract back in the lancet device by the spring 415.
- the lancet needle only projects past or beyond the plane P for a very brief time (i.e., a fraction of a second when the trigger 409 is released) and is otherwise not exposed to a user while the front cover 403 is installed thereon.
- the front cap 403 can be mounted to the body 401 in any desired manner (i.e., with or without threads) provided it functions properly in the intended manner, i.e., provided it moves axially forwards and backwards. To ensure that the front cap 403 is axially retained to body parts
- the front cap 403 has internal threads 403 c which engage external threads 402a of the intermediate section 402.
- the front cap 403 also includes chamfered corners 403b and raised projections 403a which allow a user to more securely grip the front cap 403.
- the intermediate body section 402 has an internal projecting wall 402b that includes a fixed stop surface FSS (see Fig. 32) which is configured to be engaged by a movable stop surface MSS (in particular stop surface MSS of front portion 404) that is formed on or coupled to the front portion 404 of holding member 404/405.
