Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to a stretchable hook for dialysis and a dialysis machine. Background Technology

[0002] Hemodialysis is a common treatment method widely used for renal replacement therapy in patients.

[0003] In clinical practice, it is common to use multiple bags of fluid in series with connecting tubing. For example, when using a Gambro dialysis machine, according to the doctor's prescription for the citrate mode, three 200 ml bags of citrate are hung on the same plane of the PBP scale with a bridge tube. Because the three bags of citrate are at the same height, the fluid often cannot be completely drained, resulting in waste. At the same time, during dialysis, the uniform height makes it difficult to expel air properly, causing air to enter as compensation, thus increasing the nursing workload significantly. Utility Model Content

[0004] The purpose of this invention is to provide a stretchable hook for dialysis and a dialysis machine, thereby solving the aforementioned problems in the prior art.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows:

[0006] A stretchable hook for dialysis includes a bridge tube, a hanging plate is hung on the bridge tube, two hooks are provided at the bottom of the hanging plate, and a connecting rod is provided between the two hooks and the hanging plate, wherein the length of the connecting rod on the right is longer than the length of the connecting rod on the left.

[0007] The beneficial effects of this utility model are: the hooks and two hooks on the bridge tube are stepped, which allows the height of the three liquid bags to be distributed in a stepped manner. Since the three liquid bags are located at different heights, a natural exhaust channel is created between the three liquid bags, allowing air to rise and be discharged from the system as the liquid flows out, reducing the possibility of air compensation entering. At the same time, it also avoids the problem of waste caused by the inability to completely discharge liquid when the three liquid bags are located at the same height.

[0008] Based on the above technical solution, the present invention can be further improved as follows.

[0009] Furthermore, the total weight of the hanging plate and the two hooks is grams.

[0010] The beneficial effect of adopting the above-mentioned further solution is that by setting the total weight of the hanging plate and the two hooks to grams, medical staff no longer need to tie saline bags weighing grams, thus saving unnecessary resource consumption.

[0011] Furthermore, a connecting plate is fixedly installed at the end of each of the two connecting rods away from the hook, and the connecting plate is detachably installed at the bottom of the hanging plate by bolts.

[0012] The advantages of adopting the above-mentioned further solution are: the detachable hook design means that when a hook is damaged or worn, only that hook needs to be replaced, rather than the entire mounting plate. This reduces maintenance costs and extends the overall service life.

[0013] Another technical solution of this utility model is as follows:

[0014] A dialysis machine includes a dialysis machine body, a PBP scale is slidably inserted into the bottom of the dialysis machine body, a fixing hook is fixedly installed on the PBP scale, and the bridge tube can be placed on the fixing hook.

[0015] The beneficial effects of this utility model are: it enables the liquid bag and hanging plate to be placed on the bridge tube outside the PBP scale; it avoids the disadvantages of existing dialysis machines having at least four hanging scales at the bottom of the machine body, where the space is too narrow and it is difficult to operate when the liquid bag is placed directly at the bottom of the dialysis machine body.

[0021] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0022] Example 1

[0023] like Figure 1 As shown, a stretchable hook for dialysis includes a bridge tube 1, a hanging plate 2 is hung on the bridge tube 1, and two hooks 201 are provided at the bottom of the hanging plate 2. A connecting rod 202 is provided between the two hooks 201 and the hanging plate 2, and the length of the right connecting rod 202 is longer than the length of the left connecting rod 202.

[0024] Hang the hanging plate 2 on the bridge tube 1. Then, place the three liquid bags of citric acid on the hooks and two hooks 201 on the bridge tube 1. At this time, because the two connecting rods 202 are of different lengths, the height of the hooks and two hooks 201 on the bridge tube 1 is stepped, so that the height of the three liquid bags is distributed in a stepped manner. Since the three liquid bags are at different heights, a natural exhaust channel is created between the three liquid bags, allowing air to rise and be discharged from the system as the liquid flows out, reducing the possibility of air compensation entering. At the same time, it also avoids the problem of waste caused by the three liquid bags being at the same height, which often cannot be completely discharged.

[0025] Meanwhile, both the mounting plate 2 and the two hooks 201 are made of stainless steel. Stainless steel has excellent wear resistance and can maintain its surface quality and precision even under high-intensity use. The mounting plate 2 and the two hooks 201 are prone to friction and wear during repeated use, and the stainless steel material can effectively resist this wear, maintaining the stability and reliability of the mounting plate 2 and the two hooks 201.

[0026] Example 2

[0027] like Figure 1 and Figure 3 As shown, this embodiment is a further improvement on embodiment 1, as detailed below:

[0028] The total weight of the hanging plate 2 and the two hooks 201 is 100 grams. Currently, existing dialysis machines have a minimum hanging weight requirement of 230 grams on each scale. When the dialysis bag is almost empty, on the scale with three bags hanging, the sum of the remaining fluid in the bag, bridge tube 1, and the bag connecting tube is insufficient to reach 230 grams. The machine automatically closes the drain pipe, preventing dialysis fluid from entering the system and resulting in waste. To avoid this, a 100-gram saline bag is usually attached to the machine for weight-bearing, ensuring the total weight reaches 230 grams at the end of dialysis. However, this is cumbersome, requiring the saline bag to be attached every time. Setting the total weight of the hanging plate 2 and the two hooks 201 to 100 grams eliminates the need for medical staff to attach a 100-gram saline bag, saving unnecessary resources.

[0029] Example 3

[0030] like Figure 1 As shown, this embodiment is a further improvement on embodiment 1, as detailed below:

[0031] A connecting plate 203 is fixedly installed at the end of each connecting rod 202 away from the hook 201. The connecting plate 203 is detachably installed at the bottom of the hanging plate 2 by bolts. The detachable design of the hook 201 means that when a hook 201 is damaged or worn, only that hook 201 needs to be replaced instead of the entire hanging plate 2. This reduces maintenance costs and extends the overall service life.

[0032] Example 4

[0033] like Figure 1 As shown, this embodiment is a further improvement on embodiment 1, as detailed below:

[0034] A filler ring 204 is fixedly installed on the inner wall of the two hanging holes on the hanging plate 2. By setting the filler ring 204, the gap between the hanging hole and the bridge tube 1 can be filled. By filling the gap, the filler ring 204 can enhance the connection strength between the hanging plate 2 and the bridge tube 1, thereby improving the stability of the entire structure and preventing the hanging plate 2 from shaking when it is placed on the bridge tube 1, which would affect the natural flow of liquid inside the liquid bag.

[0035] Example 5

[0036] like Figure 1 As shown, this embodiment is a further improvement on embodiment 1, as detailed below:

[0037] A handle 101 is provided on the bridge tube 1. The handle 101 makes it easy for medical staff to remove the bridge tube 1 from the machine.

[0038] like Figure 2 and Figure 3 As shown in Embodiment 6 of this utility model, a dialysis machine includes a dialysis machine body 3. A PBP scale 301 is slidably inserted into the bottom of the dialysis machine body 3. A fixing hook 302 is fixedly installed on one side surface of the PBP scale 301, and the bridge tube 1 can be placed on the fixing hook 302.

[0039] By installing fixing hooks 302 on the PBP scale 301, which are used to suspend the bridge tube 1, and the PBP scale 301 is slidably inserted into the bottom of the dialysis machine body 3, when it is necessary to place the fluid bag, the operator pulls the PBP scale 301 out of the dialysis machine body 3 and lifts the lower bridge tube 1, thus placing the fluid bag and hanging plate 2 onto the bridge tube 1 from outside the PBP scale 301. This avoids the disadvantage of the existing dialysis machine body 3 having at least four suspended scales at the bottom, which makes it too narrow and difficult to operate when placing the fluid bag directly at the bottom of the dialysis machine body 3. In specific implementation, at least two fixing hooks 302 are installed at intervals, and the bridge tube 1 rests on the fixing hooks 302.

[0040] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
