The drop-off of the infusion bag holder 100 from the infusion pump 50 can be suppressed. Furthermore, according to the weight of the infusion bag P accommodated in the accommodating part 3, if necessary, a fixing mechanism for fixing the infusion pump 50 to at least one of the attachment main body part 7a and the protruding part 7b may be further provided.

  In the present specification, “can be connected continuously” means that the housing portion 3 and the mounting portion 4 are formed of a single member, and the housing portion 3 and the mounting portion 4 are made of a plurality of members. It is the meaning which includes both the form formed and connected indirectly through the connection member etc. directly. Therefore, in FIG. 2A and the like, an integrated continuous form, which is one of the forms in which the accommodating portion 3 and the attachment portion 4 can be connected, is shown, and in FIG. The form which the some accommodating part 3 and the attachment part 4 are connected so that isolation | separation is possible is shown.

  The attachment portion 4 is preferably configured to be attached to the upper surface or the lower surface of the infusion pump. The attachment part 4 shown in FIGS. 2A to 2D and the attachment part 4 shown in FIGS. 5A and 5B referred to later are attached to the upper surface of the infusion pump 50 shown in FIG. On the other hand, the attachment part 4 shown in FIG. 7A and FIG. 7B referred later is attached to the lower surface of the infusion pump 50 shown in FIG.

  As shown in FIG. 2A and the like, a concave portion 8 is formed in the attachment portion 4. As shown in FIG. 1, a substantially frame-shaped handle portion 20 for transportation is provided on the upper part of the infusion pump 50. The infusion bag holder 100 of the present embodiment is attached to the infusion pump 50 by inserting the attachment portion 4 through the frame of the handle portion 20. In this usage mode, it is preferable that the concave portion 8 is formed at a position substantially opposite to the handle portion 20. In the present embodiment, as shown in FIGS. 2A and 2C, a through-hole is formed as a recess 8 in the central portion of the attachment main body portion 7 a whose outer shape is substantially rectangular.

  When the infusion pump 50 to which the infusion bag holder 100 is attached is transported, the infusion pump 50 can be moved with one hand by grasping the handle portion 20, but the recess 8 is formed when the handle portion 20 is grasped. It becomes easy to put a finger in the frame of the handle part 20 by this. Hereinafter, the infusion pump 50 to which the infusion bag holder 100 is attached is referred to as an “infusion device”.

  Therefore, the concave portion 8 does not have to be a through hole as shown in FIG. 2 and the like, and may be any shape or size that facilitates putting a finger into the frame of the handle portion 20. As shown in FIG. 8 to be described later, when the infusion bag holder 100 is attached by providing a fixing tool such as a screw to the infusion pump 50, the attachment by the fixing tool is facilitated by forming the recess 8 as a through hole.

  As shown in FIG. 3, the infusion bag holder 100 of this embodiment has the installation part 32 which can install the infusion tube 93 connected to the infusion bag P and the infusion pump 50 (refer FIG. 1). Specifically, the infusion bag P is accommodated in the accommodating portion 3 so that the stopper 31 of the infusion bag P is on the first opening 11 side. A bottle needle 92 is connected to the infusion bag P shown in FIG. An infusion tube 94 is connected to the bottle needle 92 shown in FIG. Furthermore, an infusion tube 93 that can visually recognize the flow rate of the liquid supplied from the infusion bag P is connected to the infusion tube 94 shown in FIG. A substantially ring-shaped installation portion 32 is provided on the side surface portion of the storage wall 2 of the storage portion 3 of the infusion bag holder 100. The drip tube 93 is fixed to the installation portion 32 so that the liquid level of the drip tube 93 is not greatly inclined. In FIG. 3, a fitting portion that surrounds the drip tube 93 is shown as an example of the installation portion 32. A fitting part can be made into C shape which lacked a part of ring, for example. Moreover, when the notch portion is forcibly opened in the radial direction, the diameter is increased, and when the opening is released, the diameter is reduced and the fitting portion can be restored to the normal state. Thus, by pressing the outer peripheral surface of the drip tube 93 against the cutout portion, the C-shaped fitting portion is expanded in diameter, and the drip tube 93 can be taken into the fitting portion. The same applies when the drip tube 93 is removed from the fitting portion serving as the installation portion 32. By pressing the drip tube 93 in the direction of the cutout portion, the C-shaped fitting portion is expanded in diameter. Thereby, the drip tube 93 can be removed from the fitting portion.

  Since the infusion bag P and the infusion tube 93 are fixed to the infusion pump 50 through the infusion bag holder 100 by providing the installation portion 32 in which the infusion tube 93 can be installed in the infusion bag holder 100, the infusion tube It is possible to easily carry the infusion bag P and the infusion pump 50 while holding in a state extending in the vertical direction.

  As shown in FIG. 3, the housing 3 is formed with a slit 5 that communicates with the first opening 11 and the second opening 12 and through which the infusion tube 94 can pass. Therefore, it is possible to easily take out the infusion bag P and the like while the infusion tube 94 is connected in a state where the drip tube 93 is fixed by the installation portion 32 from the storage space 1. Thereby, the possibility that air bubbles are mixed into the drip tube 93 can be further reduced.

  In FIG. 3, the installation part 32 is provided in the storage part 3, but the installation part can be provided at any position of the infusion bag holder as long as the liquid level of the drip tube 93 is not greatly inclined.

  Next, a description will be given of a configuration in which the accommodating portion 3 shown in FIGS. FIG. 4 is a perspective view illustrating an example of an expansion / contraction adjustment mechanism 40 that adjusts the size of the accommodation space 1 so as to be freely expandable / contractible. For convenience of explanation, FIG. 4 shows the enlargement / reduction adjustment mechanism 40 on only one side (left side) of FIG. 2C, and the same enlargement / reduction adjustment mechanism 40 may be provided on the right side of FIG. 2C. Further, in FIG. 4, for convenience of explanation, a configuration in which the bottom surface portion 9 is not inclined is illustrated, but a configuration in which the bottom surface portion 9 illustrated in FIGS. 2A to 2D is inclined may be employed.

  As shown in FIG. 4, the expansion / contraction adjustment mechanism 40 adjusts the size of the accommodation space 1 so as to be expandable / contractable according to the guide member 41 for guiding the infusion bag P (see FIG. 3) and the infusion bag P to be guided. Therefore, the expansion / contraction adjustment member 42 is slidably attached to the guide member 41, and the expansion / contraction adjustment member 42 is slidable with respect to the guide member 41. And a mechanism.

  For example, by fitting the guide rail groove 48 formed in the guide member 41 and the guide rail 49 formed in the expansion / contraction adjustment member 42, the expansion / contraction adjustment member 42 is relative to the guide member 41. It can move left and right along. Of the storage wall 2, the portion facing the left side in front view of the storage portion 3 constitutes a moving wall portion 43 that moves following the expansion / contraction adjusting member 42. Thereby, the magnitude | size of the accommodation space 1 can be adjusted so that expansion / contraction is possible. FIG. 4 shows a manually operable fixing lever 47 using a leaf spring as an example of the fixing / releasing mechanism. By operating the fixing lever 47, the expansion / contraction adjusting member 42 can be switched between a fixed state and an open state.

  Thus, by providing the expansion / contraction adjustment mechanism 40 that adjusts the size of the storage space 1 so as to be freely expandable / contractible, the size of the storage space 1 can be matched to the shape and size of the infusion bag P (see FIG. 3) to be stored. Therefore, an infusion bag of any size can be accommodated.

  Next, another embodiment of the infusion bag holder will be described with reference to FIG. FIG. 5A is a perspective view of an infusion bag holder 101 as another embodiment. FIG. 5B is a side view of the infusion bag holder 101.

  The infusion bag holder 101 shown in FIG. 5 is different from the infusion bag holder 100 described above in the positional relationship between the housing portion 3 and the attachment portion 4, but the other configurations are the same. For this reason, the above differences are mainly described here, and descriptions of common configurations are omitted.

  The attachment portion 4 of the infusion bag holder 100 shown in FIGS. 1 to 4 is located in the accommodating portion 3 at a position substantially equal to the top surface portion 21 (see FIG. 2B) of the accommodating portion 3 in the vertical direction (vertical direction in FIG. 3). In contrast, the attachment portion 4 of the infusion bag holder 101 shown in FIG. 5 is substantially the same as the bottom surface portion 9 of the storage portion 3 in the vertical direction (vertical direction in FIG. 5B). It is continuous. In other words, the attachment portion 4 shown in FIG. 5 is connected in a plane that intersects the bottom surface portion 9 of the housing portion 3.

  When the position of the attachment portion 4 with respect to the storage portion 3 is provided in a plane intersecting with the bottom surface portion 9 of the storage portion 3, the position of the bottom surface portion 9 of the storage portion 3 with respect to the infusion pump 50 (see FIG. 1) is shown in FIGS. Compared with the configuration shown in FIG. 4, the distance in the vertical direction from the installation surface of the infusion pump 50 to the bottom surface portion 9 can be increased. FIG. 6 is a view showing the infusion device in a state where the infusion bag holder 101 shown in FIG. 5 is attached to the infusion pump 50. The infusion pump 50 shown in FIG. 6 includes a leg bottom surface 51 as an installation surface. As shown in FIG. 6, the infusion tube 93 extends along the vertical direction even when the infusion bag 93 is in a use mode in which the infusion bag P connected without the infusion tube 94 is accommodated in the accommodation unit 3. Can be held in a posture. Further, since the distance in the vertical direction from the leg bottom surface 51 to the bottom surface portion 9 as the installation surface of the infusion pump 50 can be secured long, the lower end of the drip tube 93 is placed on the placement surface 52 on which the infusion pump 50 is placed. In addition, it is possible to prevent contact. Therefore, it is possible to reduce the possibility that the infusion tube 94 connected to the downstream side of the flow path of the drip tube 93 will be broken due to contact with the placement surface 52. As a result, the blockage of the flow path due to the bending of the infusion tube 94 can be suppressed.

  Next, another embodiment of the infusion bag holder will be described with reference to FIG. FIG. 7A is a perspective view of an infusion bag holder 102 as another embodiment. FIG. 7B is a side view of the infusion bag holder 102.

  The infusion bag holder 102 shown in FIG. 7 differs from the infusion bag holder 100 described above in the positional relationship between the accommodating portion 3 and the attachment portion 4, but the other configurations are the same. For this reason, the above differences are mainly described here, and descriptions of common configurations are omitted.

  The attachment portion 4 of the infusion bag holder 100 shown in FIGS. 1 to 4 is located in the accommodating portion 3 at a position substantially equal to the top surface portion 21 (see FIG. 2B) of the accommodating portion 3 in the vertical direction (vertical direction in FIG. 3). In contrast, the attachment portion 4 of the infusion bag holder 102 shown in FIG. 7 is accommodated at a position further below the bottom surface portion 9 of the accommodation portion 3 in the vertical direction (vertical direction in FIG. 5B). It continues to part 3. In other words, the attachment portion 4 shown in FIG. 7 is continuously provided below the bottom surface portion 9 of the housing portion 3.

  As shown in FIG. 7A, in the accommodation wall 2 of the present embodiment, a portion where the attachment portion 4 is continuous is extended downward in the vertical direction as compared with other portions. More specifically, in the accommodation wall 2 of the present embodiment, the plate-like portion that is continuous with the attachment portion 4 includes an extending portion 2 a that protrudes downward in the vertical direction from the bottom surface portion 9. The attachment portion 4 of this embodiment is connected to the extended portion 2a.

  With this structure, the attachment portion 4 can be attached to the lower surface of the infusion pump 50. The attachment mechanism is not particularly limited. For example, as shown in FIG. 8, an infusion bag is formed by opening a locking groove 89 such as a screw groove on the bottom surface of the infusion pump 50 and using a fixture such as a fixing screw. What is necessary is just to attach to the lower surface of the infusion pump 50 through the recessed part 8 of the attaching part 4 of the holder 100. FIG.

  When the infusion bag holder 102 is attached to the bottom surface of the infusion pump 50, the space of the handle portion 20 (see FIG. 1) of the infusion pump 50 can be secured, so that the transportability of the infusion pump is improved.

  Next, another embodiment of the infusion bag holder will be described with reference to FIG. FIG. 9 is a perspective view of an infusion bag holder 103 as another embodiment.

  In the infusion bag holder 103 shown in FIG. 9, the accommodating portion 3 and the attaching portion 4 are configured as separate members compared to the infusion bag holders 100, 101, and 102 described above, and the positions of the accommodating portion 3 and the attaching portion 4 are the same. Although the point which has the position adjustment mechanism which adjusts a relationship is different, the other structure is the same. For this reason, the above differences are mainly described here, and descriptions of common configurations are omitted.

  In FIG. 9, as an example, a configuration in which the housing portion 3 and the mounting portion 4 are connected via the connection member 13 is shown, but the present invention may be a mode in which the housing portion 3 and the mounting portion 4 are directly connected. Good.

  The position adjusting mechanism includes a connecting member 13 that can freely change the positions of the accommodating portion 3 and the attaching portion 4. With reference to FIG. 9, the relationship between the accommodating part 3 and the connection member 13 and the relationship between the attachment part 4 and the connection member 13 are demonstrated in order.

  A hook-like locking claw 15 is formed on the edge of the housing wall 2 on the second opening 12 side in the housing 3. On the other hand, the connection member 13 is comprised by the plate body provided with the some through-hole 14 penetrated in the thickness direction, and the some locking hole 18 formed in the side end surface of the both sides which oppose. A locking claw 15 can be inserted into the through hole 14 formed in the front surface of the plate-like connection member 13. The locking claw 15 is locked to the connection member 13 while being inserted into the through hole 14. Therefore, the accommodating portion 3 can be attached to the connection member 13 by inserting and engaging the locking claw 15 into the through hole 14.

  Moreover, the accommodation part 3 can also be removed from the connection member 13 by releasing the engagement of the locking claws 15. Since a plurality of through holes 14 are formed in the connecting member 13 at different positions in the vertical direction (vertical direction in FIG. 9), the height position of the housing portion 3 relative to the connecting member 13 can be arbitrarily changed. .

  Next, a plurality of locking holes 18 are formed in the side end surfaces on both sides of the connecting member 13. On the other hand, the attachment portion 4 includes a plate-like connection portion 7c that protrudes from the attachment main body portion 7a. Two connection portions 7c are provided so as to protrude from the attachment main body portion 7a, and the two connection portions 7c face each other. The connecting member 13 is disposed between the two connecting portions 7c so that the facing direction of the two connecting portions 7c and the facing direction of the side end surfaces on both sides of the connecting member 13 are substantially coincident. In the two plate-like connection portions 7 c, insertion holes having the same size as the locking holes 18 of the connection member 13 are opened. Therefore, for example, by aligning the locking hole 18 of the connection member 13 and the insertion hole of the connection portion 7 c and screwing a fixture 16 such as a fixing screw, the attachment portion 4 is attached to the connection member 13. Can be attached.

  Since a plurality of locking holes 18 are formed in the connecting member 13 at different positions in the vertical direction (vertical direction in FIG. 9), the position of the attachment portion 4 with respect to the connecting member 13 can be arbitrarily changed. .

  By the position adjusting mechanism, the accommodating portion 3 and the attachment portion 4 can be fixed in an arbitrary positional relationship in the infusion bag holder 103. Further, the infusion bag holder 103 can be widely used as a substitute for an infusion stand by the position adjusting mechanism. For example, the problem of struggling with means for holding the infusion bag above a certain height when securing a venous passage at an emergency site can be solved. Moreover, even if it is the infusion bag holder 100, 101, and 102 mentioned above, the said problem can be similarly solved if it is a use aspect which can hold | maintain so that the infusion tube 94 (refer FIG. 3 etc.) may not be obstruct | occluded.
