JPH10201823A - Hanger for infusion container and fixing belt for the same - Google Patents

Abstract

PROBLEM TO BE SOLVED: To prevent the deceleration of instillation speed with the decrease of infusion by connecting the specified number of poles through springs to vertically move one side corresponding to the weight fluctuation of infusion container and providing a hook for hanging the infusion container at the upper part of that pole. SOLUTION: A supporting pole 2 is formed from an outer pole 3 and an inner pole 4 loosely fitted into the outer pole 3, and the inner pole 4 is fixed to the outer pole 3 by a fixing spring 12 fitted on the outer pole 3. A spring 8 is interposed between the inner pole 4 and the outer pole 3 and fixed by fixing members 9 and 10. A hook part 6 is attached through a connecting pole 5 to the upper part of supporting pole 2, and an infusion container 51 is hung down by a hook 7. The fixing screw 12 is loosened and the inner and outer poles 3 and 4 are loosely fitted so that the spring 8 is compressed by the weight of infusion container 51. Because of weight decrease with infusion liquid decrease, load applied to the spring 8 is decreased. Therefore, the hook part 6 is moved up by the force of spring 8, the instillation container 51 is moved up, and the surface of liquid is raised. Thus, the surface of liquid is kept higher than the surface of liquid at the time of instillation start and the deceleration of instillation speed caused by the infusion liquid decrease can be prevented.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a suspension device for an infusion container used for injecting an infusion such as a drug solution into a patient, and a fixing belt for the suspension device.

[0002]

2. Description of the Related Art An infusion container is suspended at a high place by a hook of a suspending device, and the infusion therein is infused into a patient via an infusion tube connected to the infusion container. The infusion rate is controlled by a clamp arranged in the middle of the infusion tube. Since the infusion is injected into the patient's body by the head pressure acting on the infusion container, the infusion container is located at a higher position than the patient's heart. However, as the infusion proceeds and the liquid level in the infusion container decreases, the infusion rate decreases. For this reason, the patient is forced to perform cumbersome operations such as adjusting the infusion rate using a clamp or lifting a suspension tool so that the infusion proceeds smoothly from beginning to end. The inventor of the present invention has made intensive studies in order to solve the above-described problems, and as a result, has arrived at the next invention.

[0003]

[Means for Solving the Problems]

[1] The present invention has a supporting rod formed by connecting at least two rods via a spring so that one rod can be moved up and down due to a change in the weight of the infusion container. Provided is a suspension device for an infusion container, wherein a hook portion of the infusion container is mounted on an upper portion of the formed rod. [2] The present invention provides a fixing belt for a hanging tool, comprising a waist belt and a hanging belt, each of which is provided with the fixing member for a hanging tool according to [1].

[0004]

FIG. 1 is a schematic view showing an embodiment of a suspension device 1 for an infusion container according to the present invention, which comprises a support rod 2 and a hook 6 mounted on the upper part of the support rod 2. ing. The support rod 2 is composed of an outer rod 3 and an inner rod 4. The inner rod 4 is loosely fitted in the outer rod 3, a screw groove 11 is formed in the outer rod 3, and a fixing screw 12 is mounted on this. Thus, the inner rod 4 is fixed to the outer rod 3 by the fixing screw 12. A stand 13 is provided at the bottom of the outer rod 3. The outer rod 3 and the inner rod 4 form a fixing member 9 and a fixing member 10 of the spring 8 on the inner side, respectively, and both ends of the spring 8 are fixed to the fixing members 9 and 10. The hook 7 of the infusion container 51 is attached to the end of the hook 6, and the hook 6 is connected to the inner rod 4 via the connecting rod 5.

When the fixing screw 12 is loosened, the inner rod 4 becomes
The load of the inner rod 4, the connecting rod 5, the hook 6, and the hook 7 is transmitted to the spring 8 and the spring 8 is compressed. The compression of the spring 8 increases as the load increases,
When the load decreases, the spring 8 extends and lifts the hook 6 upward. The infusion in the infusion container 51 is transferred to the infusion tube 5
2. When the liquid is injected into the patient 54 via the needle 53, the load applied to the spring 8 decreases as the infusion in the infusion container 51 decreases, and the spring 8
Is extended and pushes up the hook part 6 so that the infusion container 51
Liquid level continues to rise above. Therefore, the liquid level in the infusion container 51 is always maintained at a higher position than at the start of the infusion, so that if the mouth 56 of the infusion container 51 is set at a position higher than the patient's heart level 55 at the start of the infusion, The infusion can always be performed at a constant speed without adjusting the position of the infusion container 51 from the start to the end of the infusion regardless of the decrease in the infusion in the infusion container 51.

In the present invention, it is desirable to transmit the load of the infusion container 51 to the spring 8 in a state that is as straight as possible. And / or dispose the infusion container 51 directly on the inner rod 4.
For example, the hanging tool 1A shown in FIG. 2 is made of a lightweight material such as an aluminum tube, and uses a small diameter connecting rod 5A and a hook 6A. The hook 1B in FIG. 3 has a hook portion 6B formed in a substantially U-shape to provide a space for accommodating the infusion container 51 so that the infusion container 51 is disposed above the inner rod 4. is there.

Further, as shown in FIG. 4, the hanging device 1 (1A, 1B) is attached to a waist belt 16 having hanging members 18 and 19, and a hanging belt 17 (perpendicularly or slightly obliquely to the waist belt 16). ) Fixed belt 15 of the suspension
Attached to, or as shown in FIG.
29 and a hanging belt 27 (the waist belt 2).
6 and the hanging belt 27 are attached substantially in parallel via the connecting belt 30), and the fixed belt 25 is used as a hanging tool, which is directly attached to the patient 54 as shown in FIG. By doing so, the burden of carrying the hanging tool 1 (1A, 1B) of the patient can be reduced, and movement can be facilitated.

[0008]

【The invention's effect】

(1) In the hanging device of the present invention, even if the liquid level in the infusion container drops, the liquid level moves to a higher place due to the decrease in the load applied to the spring of the infusion container, and the infusion speed is kept constant, so that the infusion Can be performed smoothly from beginning to end. (2) With the fixing band of the hanging device of (1), the burden of the patient carrying the hanging device can be reduced, and the patient can be easily moved.
