In the present specification, "continuously connectable" means an integrated form in which the accommodating portion 3 and the mounting portion 4 are formed of a single member, and the accommodating portion 3 and the mounting portion 4 are composed of a plurality of members. It is meant to include both a form formed and directly or indirectly connected via a connecting member or the like. Therefore, in FIG. 2A and the like, an integrated continuous form in which the accommodating portion 3 and the mounting portion 4 can be continuously connected is shown, and in FIG. 9, which will be described later, in one form that can be continuously connected. It shows a form in which the accommodating portion 3 and the mounting portion 4 are detachably connected to each other.

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

As shown in FIG. 2A and the like, the recess 8 is formed in the mounting portion 4. As shown in FIG. 1, a substantially frame-shaped handle portion 20 for transportation is provided on the upper portion 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 into the frame of the handle portion 20. In this usage mode, it is preferable that the recess 8 is formed at a position substantially facing 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 mounting main body portion 7a having a substantially rectangular outer shape.

When transporting the infusion pump 50 to which the infusion bag holder 100 is attached, it can be moved with one hand by gripping the handle portion 20, but a recess 8 is formed when gripping the handle portion 20. This makes it easier to put a finger in the frame of the handle portion 20. Hereinafter, the infusion pump 50 in which the infusion bag holder 100 is attached will be referred to as an “infusion device”.

Therefore, the recess 8 does not have to be a through hole as shown in FIG. 2, and may have a shape and size that makes it easy to insert 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 infusion bag holder 100 can be easily attached by the fixing tool by making the recess 8 a through hole.

As shown in FIG. 3, the infusion bag holder 100 of the present embodiment has an installation portion 32 on which a drip tube 93 connected to the infusion bag P and the infusion pump 50 (see FIG. 1) can be installed. 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 side of the first opening 11. A bottle needle 92 is connected to the infusion bag P shown in FIG. Further, an infusion tube 94 is connected to the downstream side of the flow path of the infusion line with respect to the bottle needle 92 shown in FIG. Further, a drip tube 93 capable of visually recognizing the flow rate of the liquid supplied from the infusion bag P is connected to the downstream side of the flow path of the infusion line with respect 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 does not tilt significantly. FIG. 3 shows a fitting portion that surrounds the drip tube 93 as an example of the installation portion 32. The fitting portion may have, for example, a C shape lacking a part of the ring. Further, when the notch portion is forcibly opened in the radial direction, the diameter is expanded, and when the opening is released, the diameter is reduced to form a fitting portion having resilience to be restored to the normal state. As a result, by pressing the outer peripheral surface of the drip tube 93 against the notch portion, the diameter of the C-shaped fitting portion is expanded, 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 as the installation portion 32. By pressing the drip tube 93 in the direction of the notch portion, the diameter of the C-shaped fitting portion is expanded. As a result, the drip tube 93 can be removed from the fitting portion.

By providing the infusion bag holder 100 with an installation portion 32 on which the drip tube 93 can be installed, the infusion bag P and the drip tube 93 are fixed to the infusion pump 50 via the infusion bag holder 100. The infusion bag P and the infusion pump 50 can be easily carried while holding the infusion bag P in a vertically extending state.

Further, as shown in FIG. 3, the accommodating portion 3 is formed with a slit 5 that communicates with the first opening 11 and the second opening 12 and allows the infusion tube 94 to pass through. Therefore, with the drip tube 93 fixed by the installation portion 32, the infusion bag P or the like with the infusion tube 94 connected can be easily taken out from the accommodation space 1. As a result, the possibility that air bubbles are mixed in the drip tube 93 can be further reduced.

In FIG. 3, the installation portion 32 is provided in the accommodating portion 3, but the installation portion can be provided at an arbitrary position of the infusion bag holder as long as the liquid level of the drip tube 93 is not significantly tilted.

Next, a configuration will be described in which the accommodating portion 3 shown in FIGS. 1 to 3 further includes a scaling adjusting mechanism 40 that flexibly adjusts the size of the accommodating space 1. FIG. 4 is a perspective view showing an example of a scaling adjustment mechanism 40 that freely adjusts the size of the accommodation space 1. FIG. 4 shows the scaling adjustment mechanism 40 on only one side (left side) of FIG. 2C for convenience of explanation, and a similar scaling adjustment mechanism 40 may be provided on the right side of FIG. 2C. Further, although FIG. 4 shows a configuration in which the bottom surface portion 9 is not inclined for convenience of explanation, the bottom surface portion 9 may be inclined as shown in FIGS. 2A to 2D described above.

As shown in FIG. 4, the expansion / contraction adjusting mechanism 40 freely adjusts the size of the accommodation space 1 according to the guide member 41 for guiding the infusion bag P (see FIG. 3) and the guided infusion bag P. Therefore, the expansion / contraction adjusting member 42 slidably attached to the guide member 41 and the expansion / contraction adjusting member 42 are switched between a slidable open state and a fixed state fixed so as not to slide with respect to the guide member 41. It has 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 adjusting member 42, the expansion / contraction adjusting member 42 refers to the guide member 41 with respect to the guide rail 49. It becomes possible to move left and right along. The portion of the accommodating wall 2 facing the left side when viewed from the front of the accommodating portion 3 constitutes a moving wall portion 43 that moves following the expansion / contraction adjusting member 42. Thereby, the size of the accommodation space 1 can be freely adjusted. Further, FIG. 4 shows a fixing lever 47 that can be manually operated using a leaf spring as an example of the fixing / opening mechanism. By operating the fixing lever 47, the expansion / contraction adjusting member 42 can be switched between the fixed state and the open state.

In this way, by providing the expansion / contraction adjusting mechanism 40 that freely adjusts the size of the accommodation space 1, the size of the accommodation space 1 is matched to the shape and size of the infusion bag P (see FIG. 3) to be accommodated. Can accommodate any size infusion bag.

Next, another embodiment of the infusion bag holder will be described with reference to FIG. FIG. 5A is a perspective view of the 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 has a different positional relationship between the accommodating portion 3 and the mounting portion 4 as compared with the infusion bag holder 100 described above, but has the same other configurations. Therefore, the above differences will be mainly described here, and the description of common configurations will be omitted.

The mounting 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). While continuous, the mounting portion 4 of the infusion bag holder 101 shown in FIG. 5 is located at a position substantially equal to the bottom surface portion 9 of the accommodating portion 3 in the vertical direction (vertical direction in FIG. 5B). It is continuous with. In other words, the mounting portion 4 shown in FIG. 5 is continuously provided in the surface intersecting the bottom surface portion 9 of the accommodating portion 3.

When the position of the mounting portion 4 with respect to the accommodating portion 3 is provided in the surface intersecting the bottom surface portion 9 of the accommodating portion 3, the position of the bottom surface portion 9 of the accommodating portion 3 with respect to the infusion pump 50 (see FIG. 1) is set in FIGS. 2A to 2D. Since it can be changed to the upper side in the vertical direction as compared with the configuration shown in the above, 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 diagram showing an infusion device in which 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 facing the installation surface. As shown in FIG. 6, even in the usage mode in which the infusion tube 93 is used to accommodate the infusion bag P connected to the infusion tube 94 without the intervention of the infusion tube 94 in the accommodating portion 3, the infusion tube 93 extends in the vertical direction. Can be held in a posture. Further, since a long vertical distance from the bottom surface 51 of the leg as the installation surface of the infusion pump 50 to the bottom surface portion 9 can be secured, the lower end of the drip tube 93 is the mounting surface 52 on which the infusion pump 50 is mounted. It can be prevented from coming into contact with the other. 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 mounting surface 52. As a result, it is possible to suppress blockage of the flow path due to bending of the infusion tube 94.

While continuous, the mounting 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 accommodating portion 3 in the vertical direction (vertical direction in FIG. 5B). It is continuous to the part 3. In other words, the mounting portion 4 shown in FIG. 7 is continuously provided below the bottom surface portion 9 of the accommodating portion 3.

As shown in FIG. 7A, in the accommodation wall 2 of the present embodiment, the portion where the mounting portion 4 is continuous is extended downward in the vertical direction as compared with the other portions. More specifically, in the accommodating wall 2 of the present embodiment, the plate-shaped portion continuous with the mounting portion 4 includes an extending portion 2a protruding downward in the vertical direction from the bottom surface portion 9. The mounting portion 4 of the present embodiment is continuously provided to the extending portion 2a.

With this structure, the mounting portion 4 can be mounted on the lower surface of the infusion pump 50. The mounting mechanism is not particularly limited. For example, as shown in FIG. 8, a locking groove 89 such as a screw groove is opened on the bottom surface of the infusion pump 50, and an infusion bag is provided with a fixing tool such as a fixing screw. It may be attached to the lower surface of the infusion pump 50 through the recess 8 of the attachment portion 4 of the holder 100.

When the infusion bag holder 102 is attached to the bottom surface of the infusion pump 50, a space for 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 the infusion bag holder 103 as another embodiment.

In the infusion bag holder 103 shown in FIG. 9, the accommodating portion 3 and the mounting portion 4 are configured by separate members as compared with the infusion bag holders 100, 101 and 102 described above, and the positions of the accommodating portion 3 and the mounting portion 4 are provided. The difference is that it has a position adjustment mechanism that adjusts the relationship, but the other configurations are the same. Therefore, the above differences will be mainly described here, and the description of common configurations will be omitted.

FIG. 9 shows, as an example, a form in which the accommodating portion 3 and the mounting portion 4 are connected via a connecting member 13, but the present invention has a form in which the accommodating portion 3 and the mounting portion 4 are directly connected. good.

The position adjusting mechanism has a connecting member 13 that can freely change the positions of the accommodating portion 3 and the mounting portion 4.
