Description

A disposable leak-proof enema irrigation device

Technical field

The utility model belongs to the technical field of medical equipment, and in particular relates to a disposable leak-proof enema irrigator

Background technique

Enema is to inject an appropriate amount of liquid and medicine through the anus to achieve the purpose of cleaning the intestines, stimulating defecation or drug treatment. Authorization announcement number: CN215740887U, a disposable dual-use enema irrigation and drainage bag, which discloses an enema irrigation and drainage bag bag, but the existing technology often encounters the following two situations during clinical enema operations for patients, which makes our enema effect poor:

1. For patients who are weak, elderly, or have loose anal sphincter, the anus cannot be closed tightly during enema. The enema liquid leaks from the anus and cannot soften the stool. The leakage liquid contaminates the bed sheets.

2. When enema drug treatment is required, retention enema is used. The patient is generally required to hold the enema liquid for more than half an hour, so that the drug can be retained in the intestine for sufficient time to ensure drug absorption. Clinical research has found that it is difficult for ordinary people to keep the enema liquid out for more than half an hour. For patients who are weak, elderly, and have loose anal sphincter, they are unable to retain the enema liquid due to the instinctive tightness of the anus. At the same time, leakage may also occur during the enema process. liquid, the therapeutic effect cannot be achieved.

Therefore, in the prior art, when enema drainage is performed on a patient, leakage is likely to occur, and thus the therapeutic effect cannot be achieved.

Utility model content

In order to solve the technical problem in the prior art that enema drainage is prone to leakage, the utility model provides a disposable leakage-proof enema irrigator, which includes a vertically arranged enema bag. The top of the enema bag is provided with a sling. It is convenient to hang the enema bag on the stand, and the enema bag is provided with a scale, which is convenient for medical staff to observe the enema liquid in the enema bag. The bottom end of the enema bag is connected to a liquid-guiding hose. The liquid-guiding hose is equipped with a control valve to control the liquid flow rate. The liquid-guiding hose on the right side of the control valve is equipped with a pressurized bag. The right end of the liquid-guiding hose passes through the connector. An enema tube is connected, and the right end of the enema tube is provided with a drainage hole. The enema tube is equipped with an anti-leakage mechanism. The anti-leakage mechanism includes an inner tube and an outer tube. A sealed liquid-passing cavity is formed between the inner tube and the outer tube. The inner tube can be slidably sleeved on the enema tube. , there is a water bag on the outer tube, the water bag is wrapped on the outer tube and connected with the liquid chamber, the outer tube on the left side of the water bag is connected with a water inlet hose, and the end of the water inlet hose is equipped with Water injection head, the water inlet hose is connected with a rubber stopper that matches the inner diameter of the inner tube. The rubber stopper is used at the end of the enema. After pulling out the enema tube, insert it into the left end of the outer tube to seal the outer tube to prevent liquid It leaks from the outer tube lumen and injects water into the water bag through the water injection head. After the water bag is filled with water, the volume increases.

Preferably, the length of the outer tube on the right side of the water bag is 0.2-0.5cm.

Preferably, the length of the outer tube on the left side of the water bag is 2cm-3cm.

Preferably, the length of the water bag is 3cm. According to the anatomical length of the anal canal (the length from the anal verge to the anal canal and rectal ring), which is about 4cm, the designed length of the water bag is 3cm.

Preferably, the outer diameter of the water bag after being filled with water is 3cm-4cm. Since the normal diameter of the anal canal is about 3-4cm when expanded, the water bag is in a shriveled state before being filled with water, and the transverse diameter can reach more than 4cm after being filled with water.

Preferably, the right end of the enema tube is in the shape of a semicircle, and a drainage hole is provided at the right end of the enema tube.

Adopting the above solution has the following advantages:

The setting of the anti-leakage mechanism: after the water bag is filled with water, it is fixed at the anus and all the enema liquid is poured into the intestine. The enema tube is pulled out of the body through the outer tube lumen, and the left end of the outer layer is plugged with a rubber stopper. The nozzle realizes the anti-leakage effect of the enema and reduces the leakage; after the enema has been completed for a period of time, when the patient needs to defecate, use a syringe to drain the water in the water bag through the water injection hole, and then pull out the anti-leakage mechanism, which is easy to use. ; The length of the water bag is 3cm, which is about 4cm according to the anatomical length of the anal canal (the length from the anal verge to the anal canal and rectal ring), which is more convenient to use; the outer diameter of the water bag after being filled with water is 3cm-4cm, due to the expansion of the anal canal. The normal diameter is about 3-4cm. The water bag is in a dry state before being filled with water. After being filled with water, the transverse diameter can reach more than 4cm, which can better block the patient's anus and avoid leakage.
