Description

  The present invention relates to a blood collection holder (needle holder) used when collecting blood in a blood collection container (blood collection tube).

  Usually, a blood collection holder is used when collecting blood used for various blood tests in a blood collection container (blood collection tube).

  As a conventional blood collection holder, a holder having a holder main body for storing a blood collection tube and a support portion that is provided at a proximal end portion of the holder main body and supports a needle body is known (for example, Patent Document 1 and Patents). Reference 2).

  The blood collection holder described in Patent Literature 1 has a cylindrical holder body made of a resin material such as polypropylene, and a plurality of thin-walled portions (integral hinges) formed along its longitudinal direction. Has been. Moreover, these thin parts are arrange | positioned at equal intervals along the circumferential direction of a holder main body, respectively. The holder main body can be easily deformed by each thin portion. Thereby, the shape of the holder body can be changed between a first state in which the shape is cylindrical and the blood collection tube can be accommodated, and a second state in which the holder body is folded by the thin portion.

  In the blood collection holder described in Patent Document 2, the holder body is composed of a pair of walls facing each other, and folds are formed along the longitudinal direction of each wall. The holder body can be easily deformed by each fold. Thereby, the shape of the holder body can be changed between a first state in which the shape is cylindrical and the blood collection tube can be accommodated, and a second state in which the holder body is folded by the fold.

  However, in the blood collection holders described in Patent Document 1 and Patent Document 2, the thickness can be kept small in the second state, and the vacuum blood collection tube is inserted in the first state. Depending on (for example, the gripping position or gripping force), the holder main body is crushed and the cylindrical shape (shape) is collapsed. For this reason, there has been a problem that the blood collection tube cannot be inserted into the blood collection holder.

Thereby, when packaging the blood-collecting holder in a folded state, for example, the size of the package can also be suppressed. Further, the size of the packaging member itself for packaging the blood collection holder can also be suppressed.

  Further, in the expanded state, each movable wall is reliably expanded outward, and a continuous wall portion is constituted by the expanded movable wall and the fixed wall. Thereby, the whole shape of the blood collection holder is surely cylindrical, and further, the cylindrical shape is maintained.

  Further, in the case of having the expanding means, when the folded holder body is set in the expanded state, for example, the fingertip is prevented from touching the needle tip of the hollow needle, so that the expanding operation can be performed safely. .

Hereinafter, the blood collection holder of the present invention will be described in detail based on preferred embodiments shown in the accompanying drawings.
FIG. 1 is an exploded perspective view of a blood collection holder (folded state) according to the present invention, FIG. 2 is a view (plan view) of the blood collection holder shown in FIG. 1 as viewed from the tip side, and FIG. 4 and FIG. 5 are longitudinal sectional views of the blood collection holder shown in FIG. 3, and FIG. 6 to FIG. 10 are views showing the blood collection holder according to the present invention changing from the folded state to the deployed state, respectively. It is a figure which shows a process in order. In the following, for convenience of explanation, the upper side in FIGS. 1 and 3 to 5 is referred to as a “tip”, and the lower side is referred to as a “base end”. 2 and 3, the lid is omitted.

  The blood collection holder 1 shown in each figure is a blood collection holder assembly with a hollow needle 20 attached to the inside thereof (blood collection holder assembly). The hollow needle 20 includes a long needle body 201, a hub 202 fixed to a proximal end portion of the needle body 201, and a rubber sheath (covering member) 204 (see FIG. 2). The needle body 201 has a sharp needle tip 203 at its tip (see FIG. 5). The hub 202 is a member that fixes the needle body 201 to the blood collection holder 1, and has a cylindrical shape whose diameter is larger than that of the needle body 201.

  Moreover, it is not specifically limited as what is installed in the base end side of the hollow needle 20, However, In this embodiment, the blood bag (blood bag for a test | inspection) (not shown) which stores the blood used for various blood tests Is an example. The blood bag is connected to the hub 202 via a tube or a connector and communicates with the needle body 201.

  A sharp needle tip may be formed on the proximal end side of the hollow needle 20 in the same manner as the distal end side. That is, the hollow needle 20 may be a double-ended needle. In this case, blood used for various blood tests can be collected directly from a donor (donor or patient) as well as from a blood bag.

  A blood collection holder 1 shown in FIG. 1 includes a holder body 2, a bottom plate (bottom part) 5 formed integrally with a base end portion of the holder body 2, and a lid body that is detachably attached to the distal end portion of the holder body 2. (Expanding means) 6. The blood collection holder 1 can be deformed into a folded state (the state shown in FIG. 1) in which the holder main body 2 is folded and a developed state (the state shown in FIG. 3) in which the holder main body 2 is unfolded. It is configured to be able to.

  The unused blood collection holder 1 is packaged (contained) in a folded state by a packaging member (not shown) such as a blister packaging material. When this blood collection holder 1 is used, it is taken out from the packaging member. The blood collection holder 1 packaged by the packaging member may be one in which the hollow needle 20 is mounted in advance (blood collection holder assembly), or the hollow needle 20 may be unmounted.

  As shown in FIG. 3, the blood collection holder 1 is inserted with a blood collection tube (blood collection container) 30 for taking out (collecting) blood from the blood bag in the deployed state from the distal end side. The blood collection tube 30 includes a main body 301 having a bottomed cylindrical shape and a plug 302 that seals the opening of the main body 301. The main body 301 has a substantially circular cross-sectional shape and is made of a material having transparency such as various resin materials (for example, polypropylene) and various glass materials. The plug 302 has a disk shape and is made of a rubber material such as isoprene rubber. The blood collection holder 1 has the hollow needle 20 attached to the bottom plate 5 in the deployed state.

Next, each part (member) constituting the blood collection holder 1 will be described.
As shown in FIG. 1, the bottom plate 5 has a flat plate shape, and has a fixing portion 51 for mounting (supporting) the hollow needle 20 at the center thereof. The fixing portion 51 is a tubular portion projecting in the proximal direction. The hollow needle 20 is attached to the fixing portion 51 by, for example, fitting or screwing the hub 202 of the hollow needle 20.

  Further, the two edge portions 52 positioned (opposed) in the longitudinal direction of the bottom plate 5 (vertical direction in FIG. 2) are curved outward (outside), respectively.

  Further, when assuming a circle with each edge 52 as a circular arc, it can be said that there are two deficient portions formed in an arcuate shape in the width direction of the bottom plate 5 (the left-right direction in FIG. 2). Each defect portion constitutes (forms) two opposing flat edge portions 53.

  In such a bottom plate 5, the length between both edge portions 53 is shorter than the length between both edge portions 52. Thereby, the size (width) of the entire blood collection holder 1 can be reliably suppressed in the folded state. Therefore, for example, when the folded blood collection holder 1 is packaged, the size of the package can also be suppressed. Further, the size of the packaging member itself for packaging the blood collection holder 1 can also be suppressed.

  As shown in FIGS. 1 to 3, the holder body 2 is provided so as to be rotatable (displaceable) between a pair of fixed walls 3 a and 3 b fixed to the bottom plate 5 and the fixed walls 3 a and 3 b. It has a pair of movable walls 4a and 4b. In the blood collection holder 1, the fixed walls 3 a and 3 b are arranged to face each other via the hollow needle 20, and similarly, the movable walls 4 a and 4 b are arranged to face each other via the hollow needle 20. An inner space 21 is defined (formed) inside the holder body 2 by the fixed walls 3a and 3b and the movable walls 4a and 4b arranged in this manner. In this internal space 21, the hollow needle 20 (needle body 201) is positioned (stored).

  The fixed walls 3a and 3b are each constituted by a plate piece standing from each edge portion 52 of the bottom plate 5, and face each other through the hollow needle 20 (internal space 21). Since the configuration of the fixed wall 3a and the configuration of the fixed wall 3b are substantially the same, the fixed wall 3a will be described below representatively.

  The fixed wall 3a is curved outward as in the edge portion 52 of the bottom plate 5 corresponding thereto. That is, the fixed wall 3a is formed along the edge 52 of the bottom plate 5 corresponding to it.

  The fixed wall 3a is set so that the maximum width is shorter than the length between both edge portions 53 of the bottom plate 5 (see FIG. 2). As a result, the fixed wall 3a is positioned (contained) inside the bottom plate 5, so that both edge portions 31 of the fixed wall 3a are prevented from protruding from the corresponding edge portions 53, respectively. Thereby, the thickness of the whole blood collection holder 1 can be more reliably suppressed in the folded state, and therefore the size of the package when the folded blood collection holder 1 is packaged, for example, can be suppressed.

  A flange 321 projects from the distal end side of the outer peripheral portion 32 of the fixed wall 3a. The flange 321 is a small piece having an arc shape, and the length thereof is substantially the same as the length between both edge portions 53 of the bottom plate 5. Thereby, like the above, the width | variety of the blood collection holder 1 can be more reliably suppressed in a folded state.

  Further, when the blood collection tube 30 is pushed (inserted) into the inner space 21 of the blood collection holder 1 in the expanded state, the pushing operation can be performed by placing a finger on each flange 321 of the fixed walls 3a and 3b. Further, since each flange 321 is not provided on the movable wall 4a (the same applies to the movable wall 4b) but is provided on the fixed wall 3a, the finger is stably hooked on the flange 321 when performing the pushing operation. be able to. Thereby, pushing operation (insertion operation) can be performed reliably.

  As shown in FIG. 2, a projecting portion (folded state maintaining means) 34 is formed to project over the inner peripheral portion of the fixed wall 3 a and the bottom plate 5. The protrusion 34 is a part having a long block shape. The outer peripheral portion 42 of the movable wall 4a in a folded state is in contact with the end surface 341. Thereby, a folding state can be maintained reliably. For example, when the blood collection holder 1 is wrapped in a packaging member in a folded state, it is possible to reliably prevent the movable wall 4a from rotating unintentionally in the packaging member, that is, unintentionally unfolding. it can. Thus, the protrusion 34 has a function as a folded state maintaining means for maintaining the folded state.

  Moreover, the one edge part 31 of the fixed wall 3a is provided with the rotation support part 35 which supports the movable wall 4b so that rotation is possible (for example, refer FIGS. 1-3). A through-hole (concave portion) 36 that penetrates the outer peripheral portion 32 from the inner peripheral portion 33 of the fixed wall 3a is provided on the distal end side of the other edge portion 31 of the fixed wall 3a (for example, FIG. 1 and FIG. 4). FIG. 5).

  Although it does not specifically limit as a structure of the rotation support part 35, For example, it may be comprised by the rotating shaft and the bearing, and was comprised by the thin part integrally formed with the edge part 31. It may be a thing. With such a configuration, the movable wall 4b can be easily and reliably rotated with respect to the fixed wall 3a. In addition, the rotation support part 35 is the former structure in the structure shown in FIG.

  The through-hole 36 is a portion where a later-described claw portion 41 of the movable wall 4a that the fixed wall 3b rotatably supports is engaged in a deployed state (see FIGS. 4 and 5). In addition, the part with which this nail | claw part 41 engages is comprised by the concave-shaped part. In this embodiment, the concave portion is configured by a through hole 36 that penetrates the outer peripheral portion 32 from the inner peripheral portion 33 of the fixed wall 3a. However, the present invention is not limited to this, and for example, the inner peripheral portion 33 of the fixed wall 3a. It may be constituted by a concave portion that does not reach the outer peripheral portion 32.

  As described above, the movable wall 4b is rotatably supported by the fixed wall 3a via the rotation support portion 35. Further, the movable wall 4a is rotatably supported by the fixed wall 3b via a rotation support portion 35. Since the configuration of the movable wall 4a and the configuration of the movable wall 4b are substantially the same, the movable wall 4a will be described below representatively.

  The movable wall 4a is composed of a plate piece curved outward. The circumferential length of the outer peripheral portion 42 of the movable wall 4a is substantially equal to the circumferential length of the outer peripheral portion 32 of the fixed walls 3a and 3b. Further, the height of the movable wall 4a is substantially equal to the height of the fixed walls 3a and 3b.

  As shown in FIGS. 1 and 2, in the folded state, the movable wall 4 a is folded toward the center portion (hollow needle 20) side of the holder main body 2, and most of the movable wall 4 a is located inside the bottom plate 5. (Stored). Thereby, in the folded state, the movable wall 4a is suppressed as much as possible from protruding from the edge 53 of the corresponding bottom plate 5 (below it), and thus the width of the entire blood collection holder 1 is more reliably suppressed. Can do. For example, when the folded blood collection holder 1 is packaged, the size of the package can be suppressed.

  Further, since the shape of the movable wall 4a is curved outward, the inner peripheral portion 43 is prevented from touching the hollow needle 20 in the folded state. Thereby, the unintentional deformation | transformation (for example, bending and bending) of the needle main body 201 of the hollow needle 20 can be prevented reliably.

  The movable wall 4a and the movable wall 4b are arranged point-symmetrically with respect to the hollow needle 20, and rotate in the same direction (counterclockwise) when shifting from the folded state to the expanded state. Thereby, the movable wall 4a and the movable wall 4b located inside the bottom plate 5 can be collectively expanded (rotated) toward the outside by one rotation operation with respect to the lid body 6 described later.

  When the movable wall 4a and the movable wall 4b are deployed, the lower ends of the movable walls 4a and 4b may slide with respect to the bottom plate 5, and the lower ends of the movable walls 4a and 4b It may be slightly separated from the bottom plate 5 and rotated without contacting the bottom plate 5.

  When the movable wall 4a and the movable wall 4b are deployed outward, the blood collection holder 1 (holder body 2) is in a deployed state. In this unfolded state, the movable walls 4a and 4b and the fixed walls 3a and 3b constitute a continuous wall portion. Thereby, the holder main body 2 has a cylindrical shape as a whole, and thus the blood collection tube 30 can be reliably inserted into the internal space 21 (see FIG. 3).

  In the present embodiment, in the deployed state, the movable wall 4a, the fixed wall 3a, the movable wall 4b, and the fixed wall 3b are arranged in this order at equiangular intervals with the hollow needle 20 as the center.

  On the outer peripheral portion 42 of the movable wall 4a (the same applies to the movable wall 4b), a protruding claw portion 41 is disposed at a position corresponding to the through hole 36 of the fixed wall 3a. The claw portion 41 engages with the through hole 36 of the fixed wall 3a in the expanded state (see FIGS. 4 and 5). Thereby, a deployment state can be maintained reliably. For example, when the blood collection tube 30 is to be inserted into the blood collection holder 1 in the expanded state, it is possible to reliably prevent the movable walls 4a and 4b from rotating unintentionally, that is, unintentionally folded. As described above, in the blood collection holder 1, each nail portion 41 and the corresponding through hole 36 or the above-described concave portion, that is, each nail portion 41 and each concave portion constitutes an unfolded state maintaining means. I can say that.

  The constituent material of the holder body 2 (including the bottom plate 5) is not particularly limited. For example, polyolefin such as polyethylene, polypropylene, ethylene-vinyl acetate copolymer, polyurethane, polyamide, polyester, polycarbonate, polybutadiene, poly Various resin materials such as vinyl chloride are listed. By using such a constituent material, each of the fixed walls 3a and 3b and the bottom plate 5 can be easily formed integrally with a mold, for example.

  A lid 6 is detachably attached to the tip of the holder body 2. As shown in FIGS. 6 to 10, the lid body 6 functions as an unfolding means for unfolding the holder body 2 in a folded state until the unfolded state, with the cover body 6 being mounted on the tip of the holder body 2. is there.

  As shown in FIGS. 1, 4, and 5, the lid 6 includes a flat top plate 61, a gripping portion 62 provided on the top surface (front end side surface) of the top plate 61, and the top plate 61. It has four engaging pieces (engaging portions) 63, two sliding portions (bosses) 64, and two pressing pieces (pressing portions) 65 provided on the lower surface.

  The top plate 61 has a planar shape corresponding to that of the bottom plate 5, that is, substantially the same shape as the bottom plate 5. The two edge portions 611 located in the longitudinal direction of the top plate 61 are curved outward.

  Four engaging pieces 63 are formed on the lower surface of the top plate 61 so as to protrude downward. In these four engagement pieces 63, two engagement pieces 63 are arranged along each edge 611 as a set.

  A claw portion 631 protruding toward the center of the top plate 61 is integrally formed inside each engagement piece 63. As shown in FIGS. 4 and 5, the claw portion 631 is a rib (in a mounted state) that protrudes along the circumferential direction from the distal end portion of the outer peripheral portion 32 of the fixed wall 3a (the same applies to the fixed wall 3b). Ridge) 322 is engaged. Thereby, the lid body 6 is supported by the fixed walls 3a and 3b so as to be rotatable around the axis of the hollow needle 20.

  Near the central portion of the lower surface of the top plate 61, two sliding portions 64 protrude downward and are integrally formed. These sliding portions 64 are arranged substantially on the diagonal line of the top plate 61 (see, for example, FIG. 6). Each sliding portion 64 has a columnar shape, and its outer peripheral portion (outer peripheral surface) corresponds to a fixed wall (fixed wall 3a or fixed wall) when the lid body 6 is rotated in the mounted state. 3b) is slid along the circumferential direction (see FIG. 7).

  In addition, two pressing pieces 65 protrude downward and are integrally formed on the lower surface of the top plate 61. These pressing pieces 65 are opposed to each other through the central portion of the top plate 61 along the longitudinal direction of the top plate 61 (see, for example, FIG. 6). In addition, each pressing piece 65 is disposed outside the sliding portion 64 and inside the engaging piece 63. Each pressing piece 65 formed in this way faces the inner peripheral portion 33 of the corresponding fixed wall (fixed wall 3a or fixed wall 3b) outward when the lid body 6 is rotated in the mounted state. And press (see FIGS. 8 and 9).

  Although it does not specifically limit as a constituent material of the cover body 6, For example, the constituent material similar to the holder main body 2 can be used.

  Next, the process from the folded state to the unfolded state by rotating the lid 6 in the mounted state will be described with reference to FIGS. Since the operation of the movable wall 4a and the operation of the movable wall 4b are the same, hereinafter, the operation of the movable wall 4a and the sliding portion 64 and the pressing piece 65 of the lid 6 corresponding to the movable wall 4a will be described. The action will be described representatively.

  [1] As shown in FIG. 6, the holder body 2 is in a folded state. A lid 6 is attached to the tip of the holder body 2. As described above, in the mounted state, each engagement piece 63 of the lid 6 is engaged with the corresponding rib 322 of the fixed wall 3a or 3b. Thereby, the unintentional detachment | leave of the cover body 6 is prevented.

  In the state shown in FIG. 6, the movable wall 4a is in contact with the protrusion 34 of the fixed wall 3a. Thereby, the position of the movable wall 4a is regulated.

  Further, the sliding portion 64 of the lid body 6 is located (contacted) inside the movable wall 4a, and the pressing piece 65 is located outside the movable wall 4a. The pressing piece 65 is located (contacted) inside the fixed wall 3b.

  [2] From the state shown in FIG. 6, the grip portion 62 is gripped and the lid body 6 is rotated by a predetermined angle in a predetermined direction (clockwise in FIG. 7) (see FIG. 7). Thereby, first, the sliding part 64 begins to rotate around the axis of the hollow needle 20. The sliding portion 64 presses the inner peripheral portion 43 outward while sliding with respect to the inner peripheral portion 43 of the folded movable wall 4a. At this time, the movable wall 4a gets over the protrusion 34 of the fixed wall 3a, and the restriction by the protrusion 34 is released. Thereby, the movable wall 4a starts to rotate counterclockwise around the rotation support portion 35.

  [3] From the state shown in FIG. 7, the lid 6 is further rotated by a predetermined angle in a predetermined direction (clockwise in FIG. 8) (see FIG. 8). At this time, the movable wall 4a is rotated by the pressing action of the sliding portion 64 as described above, but the sliding portion 64 has a position that becomes a pressing limit at which the movable wall 4a cannot be pressed outward. Therefore, when the sliding part 64 exceeds this position, it cannot be rotated by the action of the sliding part 64.

  Therefore, in order to compensate for the pressing action of the sliding portion 64 against the movable wall 4a, instead of the sliding portion 64, the pressing piece 65 slides against the inner peripheral portion 43 of the movable wall 4a. The inner peripheral portion 43 is pressed outward. When the sliding portion 64 exceeds the pressing limit, the pressing piece 65 moves from the inner peripheral portion 33 of the fixed wall 3b to the inner peripheral portion 43 of the movable wall 4a. At this time, the pressing piece 65 starts to press outward with the inner peripheral portion 33 of the fixed wall 3b (see FIG. 8).

  [4] From the state shown in FIG. 8, the lid 6 is further rotated by a predetermined angle in a predetermined direction (clockwise in FIG. 9) (see FIG. 9). As a result, the movable wall 4a is further rotated by the pressing action of the pressing piece 65 as described above, and finally the movable wall 4a is expanded until the movable wall 4a reaches the expanded state, so that the holder body 2 is in the expanded state. . At this time, since the claw portion 41 of the movable wall 4a is engaged with the through hole 36 of the fixed wall 3a, the unfolded state is reliably maintained.

  [5] From the state shown in FIG. 9, the lid body 6 is further rotated by a predetermined angle in a predetermined direction (clockwise in FIG. 10) (see FIG. 10). Thereby, each engagement piece 63 of the lid 6 is detached from the rib 322 of the corresponding fixed wall (fixed wall 3a or 3b). Therefore, the engagement of the lid body 6 with respect to the holder body 2 is released, and the lid body 6 can be removed in the distal direction (front side in FIG. 10).

  In the blood collection holder 1 having such a configuration, the unfolding operation can be performed via the lid 6 when the folded holder body 2 is in the unfolded state. Thus, when the holder body 2 is expanded, for example, the fingertip is prevented from touching the hollow needle 20, and the operation can be performed safely. Moreover, since the movable walls 4a and 4b can be unfolded collectively, the holder main body 2 unfolds quickly.

  Further, the blood collection tube 30 can be inserted into the holder main body 2 (within the internal space 21) with the lid 6 removed. When the blood collection tube 30 is inserted, the needle body 201 pierces the plug 302. Thereby, the blood collection tube 30 and the blood bag communicate with each other through the needle body 201, and blood can be taken into the blood collection tube 30 from this blood bag.

  In addition, after the blood collection holder 1 is used, the blood collection holder 1 is discarded. At this time, the blood collection holder 1 may be folded again and discarded.

  As described above, the illustrated embodiment of the blood collection holder of the present invention has been described. However, the present invention is not limited to this, and each part constituting the blood collection holder has an arbitrary configuration that can exhibit the same function. Can be substituted. Moreover, arbitrary components may be added.
