Description

Technical Field

[0001] The utility model belongs to the technical field of medical equipment, and in particular relates to a disposable closed digestive fluid reinfusion device. Background Art

[0002] Gastrointestinal drainage and T-tube insertion after gastrointestinal fistula and abdominal surgery can cause loss of digestive fluid, resulting in dehydration and electrolyte imbalance. Therefore, in clinical practice, medical staff will promptly return the leaked digestive fluid to the patient's intestines to maintain the integrity of the digestive process; the conventional method of returning the digestive fluid is to first filter the outflowing digestive fluid with double-layer gauze, and then put the filtered digestive fluid into a gastrointestinal bag for return.

[0003] In a Chinese patent with the announcement number CN209378119U, a disposable closed digestive fluid reinfusion device is disclosed, which can filter and reinfuse digestive fluid in a fully sealed state, thereby preventing electrolyte disorders or digestive abnormalities in patients due to a large amount of digestive fluid loss; at the same time, the filtration of the drainage bag and the reinfusion pipeline and the closed reinfusion structure can make the operation simple and easy, reduce the workload of nurses, and effectively prevent the smell of digestive fluid from spreading into the air.

[0004] In the above-mentioned comparative patent, a filter layer is set in the filter cavity to achieve the purpose of filtering the digestive fluid. However, due to the high viscosity of the digestive fluid, even if two filter layers are set, the filter layer may still be blocked in actual use, causing the digestive fluid to accumulate above the filter layer and difficult to drip quickly. Therefore, a disposable closed digestive fluid reinfusion device is proposed to solve the above problem. Utility Model Content

[0005] The utility model aims to provide a disposable closed digestive fluid reinfusion device to solve the problems raised in the above background technology.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A disposable closed digestive fluid reinfusion device, comprising:

[0008] A drainage bottle, wherein the upper and lower ends of the drainage bottle are respectively provided with a digestive fluid inlet and a digestive fluid outlet;

[0009] A return pipe, the return pipe comprises a filter bottle, a liquid inlet pipe and a liquid discharge pipe, the liquid inlet pipe and the liquid discharge pipe are respectively fixed at the upper and lower ends of the filter bottle, the pipe head of the liquid inlet pipe is installed in cooperation with the digestive fluid outlet, and the liquid discharge pipe is used to return the digestive fluid to the patient's gastrointestinal tract;

[0010] The filtering mechanism comprises a supporting frame and a gauze filter sleeve, wherein the supporting frame is fixedly mounted on the inner bottom of the filtering bottle, and the gauze filter sleeve is sleeved on the outer side of the supporting frame and fixedly connected to the inner bottom of the filtering bottle.

[0011] Preferably, the support frame includes support rods and a top plate, the support rods are fixed to the inner bottom of the filter bottle in a circular array, the top plate is fixedly mounted on the top of the support rods, and the inner side surface of the gauze filter sleeve is in extrusion contact with the support rods.

[0012] Preferably, the drainage bottle and the filtering bottle are both made of bendable and deformable medical rubber material.

[0013] Preferably, a hanging strap is fixedly connected to the upper end of the drainage bottle.

[0014] Preferably, a pipe clamp is installed on the liquid inlet pipe.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] The utility model arranges the filter bottle to be bendable and deformable. When digestive fluid accumulates in the filter bottle and cannot quickly pass through the gauze filter sleeve, the filter bottle can be rubbed and squeezed to force the digestive fluid to pass through the gauze filter sleeve to complete the filtration. At the same time, when the filter bottle is rubbed, the inner wall of the filter bottle rubs against the gauze filter sleeve, which can relieve blockage and restore the filtration speed. By providing a support frame, the gauze filter sleeve will not be compressed and folded, so that the disposable closed digestive fluid reinfusion device can filter the digestive fluid faster.

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. It should be pointed out that the drawings are schematic and not drawn to scale. For the sake of clarity and convenience in the figures, the relative sizes and proportions of the parts shown in the figures are exaggerated or reduced in size, and any size is only exemplary and not restrictive.

[0022] Example:

[0023] See also Figure 1 and Figure 2 As shown, the disposable closed digestive fluid reinfusion device comprises:

[0024] A drainage bottle 1, wherein a digestive fluid inlet 11 and a digestive fluid outlet 12 are respectively provided at the upper and lower ends of the drainage bottle 1;

[0025] The return pipe 2 includes a filter bottle 21, a liquid inlet pipe 22 and a liquid discharge pipe 23. The liquid inlet pipe 22 and the liquid discharge pipe 23 are respectively fixed at the upper and lower ends of the filter bottle 21. The pipe head of the liquid inlet pipe 22 is installed in cooperation with the digestive fluid outlet 12. The liquid discharge pipe 23 is used to return the digestive fluid to the patient's gastrointestinal tract.

[0026] The filter mechanism 3 includes a support frame 31 and a gauze filter sleeve 32 . The support frame 31 is fixedly mounted on the inner bottom of the filter bottle 21 . The gauze filter sleeve 32 is sleeved on the outer side of the support frame 31 and fixedly connected to the inner bottom of the filter bottle 21 .

[0027] Specifically, the drainage bottle 1 and the filtering bottle 21 are both made of bendable and deformable medical rubber material.

[0028] As can be seen from the above, due to the setting of the filtering mechanism 3, the digestive fluid flowing into the filter bottle 21 will penetrate from the outside of the gauze filter sleeve 32 to the inside. The gauze filter sleeve 32 forms an inverted cylindrical shape under the support of the support frame 31, and the contact surface with the digestive fluid is larger, which is more conducive to the filtering. At the same time, due to the high viscosity of the digestive fluid, it is easy to stick to and clog the gauze filter sleeve 32, making the filtration speed very slow. By squeezing the filter bottle 21, the digestive fluid can quickly pass through the gauze filter sleeve 32. At the same time, when the digestive fluid in the drainage bottle 1 is less and difficult to flow downward and discharge quickly, the digestive fluid can be forced to flow out by folding and compressing the drainage bottle 1.

[0029] Specifically, by Figure 2 It can be seen that the support frame 31 includes a support rod 311 and a top plate 312. The support rod 311 is fixed to the inner bottom of the filter bottle 21 in a circular array, and the top plate 312 is fixedly installed on the top of the support rod 311. The inner side of the gauze filter sleeve 32 is in squeeze contact with the support rod 311.

[0030] As can be seen from the above, under the support of the support rod 311 and the top plate 312, when the filter bottle 21 is squeezed and kneaded, the gauze filter sleeve 32 will not fold up.

[0031] Specifically, by Figure 1 It can be seen that a hanging strap 4 is fixedly connected to the upper end of the drainage bottle 1 .

[0032] As can be seen from the above, by providing the hanging belt 4, it is convenient to hang the drainage bottle 1.

[0033] Specifically, by Figure 1 It can be seen that a pipe clamp 5 is installed on the liquid inlet pipe 22 .

[0034] As can be seen from the above, by setting the tube clamp 5, the liquid inlet tube 22 can be blocked to prevent the digestive fluid from flowing upward and returning to the drainage bottle 1 when the filter bottle 21 is squeezed.
