Description

A rectal administration tube sealing assembly, a collecting bag, an enema auxiliary device and an assembly method thereof, and an enema excrement collecting method TECHNICAL FIELD

[0001] The present application belongs to the field of medical and health devices, and particularly relates to a rectal administration tube sealing assembly, a collecting bag, an enema auxiliary device, and an enema excrement collecting method. BACKGROUND

[0002] Enema is widely used in hospitals, mainly for two purposes: one is to clean the intestines before surgery to prevent fecal contamination of the operating table during surgery after anesthesia; and the other is to assist in the excretion of feces for hospitalized patients who have difficulty in self-defecation. The specific method is to inject enema drugs into the rectum through the anus of the patient, and then the patient goes to the bathroom to excrete feces.

[0003] Among enema patients, a large part of them cannot go to the bathroom by themselves due to loss of action ability and need to excrete on the bed. Currently, the commonly used method in clinical practice is to directly excrete on a nursing pad, but this method has the following disadvantages:

[0004] 1. It often leads to large-area excrement pollution, emits a pungent odor, increases the difficulty of cleaning work, and makes the patient uncomfortable.

[0005] 2. Some patients excrete feces during enema administration, which affects the enema operation.

[0006] 3. Another method is to use a fecal drainage device, which needs to be inserted into the rectum of the patient and left for a long time. However, this device can only drain a small amount of watery or loose stool, is prone to blockage, needs to be operated by a professional, is expensive, and has great limitations.

[0007] Therefore, how to simply, cleanly and hygienically collect enema excrement has become a major problem to be solved in current clinical enema. SUMMARY

[0008] Technical problem: The technical problem to be solved by the present application is to effectively seal and isolate the delivery section and the administration section of the rectal administration tube during drug delivery, and to collect excrement on this basis to reduce the difficulty of subsequent processing.

[0009] Technical solution: In view of the above technical problem, the present application adopts a temporary wearing method. Before enema, a specially designed disposable collecting bag is fixed at the patient's anus opening by a silicone ring in a reverse installation manner, and feces is excreted into the collecting bag. A plastic administration nozzle is installed on the collecting bag, and medical staff inserts a rectal administration tube into the patient's anus through the administration nozzle to administer enema. After the administration tube is pulled out after enema, the patient starts to excrete feces into the collecting bag, and the collecting bag is removed after defecation is completed.

[0010] The specific technical solutions are as follows:

[0011] A rectal administration tube sealing assembly comprises a passing hole for a rectal administration tube to pass through a nozzle, and a sealing ring layer is arranged on the inner wall of the passing hole;

[0043] S3: pulling out the rectal administration tube after completing the enema operation, covering the rubber plug, and taking off the collecting bag for subsequent treatment after the discharge is completed.

[0044] The application has the following beneficial effects:

[0045] 1. By using the sealing assembly, the sealing ring layer made of silica gel is used to isolate the delivery section and the administration section of the rectal administration tube, so that the sealing effect and isolation performance are improved. The administration tube can move forward and backward in the through hole, which not only avoids affecting the pushing of the administration tube, but also provides a basic condition for connecting the collecting bag on the sealing assembly.

[0046] 2. The collecting bag is installed on the sealing assembly, and the feces are directly discharged into the collecting bag. This method can effectively collect the feces and reduce the difficulty of subsequent treatment.

[0047] 3. By fixing the disposable collecting bag at the anus of the patient, the enema operation and feces collection can be conveniently performed. The medical staff can insert the rectal administration tube into the anus of the patient through the administration nozzle, and no feces will leak out during the enema process. After the enema is completed, the patient can discharge feces into the collecting bag by himself.

[0048] The bag opening of the collecting bag is reversely turned and tightly attached to the contact surface after passing through the discharge hole, and will not fall off, and plays a role in isolating feces from the entire fixing seat, so that the fixing seat can be kept clean and reused, thereby reducing the use cost.

[0049] 4. The sealing assembly adopts the first fastener and the second fastener which are buckled with each other, and is limited and fixed through the clamping groove and the clamping seat, so that the stability and reliability of the sealing member are improved. In addition, the buffer washer can offset the problems such as loose buckling caused by the tolerance in the production process, so as to ensure the sealing effect.

[0050] 5. After the enema operation is completed, the rectal administration tube is easily pulled out, the rubber plug is covered, and the collection bag is removed for subsequent treatment after excretion, so as to reduce cross infection and environmental pollution problems in the treatment process.
