Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and specifically relates to an enema device for radiation enteritis caused by rectal cancer radiotherapy. Background Technique

[0002] Rectal cancer refers to cancer between the dentate line and the rectosigmoid junction, and it is one of the most common malignant tumors in the digestive tract. Since surgery cannot ensure complete resection of the entire tumor, radiotherapy can be used to kill tumor cells at this time, so as to control the tumor and prolong life. However, during the radiotherapy of rectal cancer, the intestinal mucosal cells are inhibited from renewing after irradiation, the small arteries are swollen and occluded, causing intestinal wall ischemia and mucosal erosion. In severe cases, it will lead to bloody stools or constipation, which is radiation enteritis. When treating radiation enteritis, patients need to be given a retention enema.

[0003] When medical staff perform an enema on a patient, they need to first lubricate the head of the enema tube, then manually insert the enema tube into the patient's anus to a depth of 6 to 10 cm, then inject normal saline, then use enema fluid for cleaning, and finally pull out the enema tube. The entire process of inserting and removing each enema tube depends entirely on manual operation. Therefore, the force is difficult to control, and it is easy to cause uneven speed, causing irritation or damage to the patient's anus. The operation process of the enema device is cumbersome, increasing the workload of medical staff. For this reason, we have designed an enema device for radiation enteritis caused by rectal cancer radiotherapy. Summary of the Invention

A number of blocking blocks 222 are fixedly arranged at the other end of the movable sleeve 220, and two liquid permeating holes 223 are opened on the surface of the movable sleeve 220.

[0042] Working principle: When in use, first, a medical staff holds the handheld sleeve 201, and slowly inserts the silica gel head 205 at the front end of the enema intubation tube 203 into the anus. Then, the micro motor 226 is started by using the enema switch 202. The micro motor 226 drives the driving screw 206 to rotate, and then drives the driving block 207 on the surface of the driving screw 206 to move. The driving block 207 drives the enema intubation tube 203 to move outwards in the sliding through hole at the front end of the handheld sleeve 201, and then drives the enema nozzle 204 to move into the anus, so that the silica gel head 205 slowly enters to a position 10 cm inside the anus. Then, the first button 307 on the surface of the fixed shell 301 is pressed to open the first electromagnetic switch valve 305. The disinfectant in the disinfection storage cavity 6 is input into the rubber hose 225 by using the first liquid outlet pipe 302, and the disinfectant is input into the enema intubation tube 203 from the telescopic hose 224 by using the micro pump 233. Then, the disinfectant is input into the liquid spraying hole 218 of the silica gel head 205 through the enema intubation tube 203 to clean the anus with the disinfectant. Then, the first electromagnetic switch valve 305 is closed, and the second electromagnetic switch valve 306 is opened through the second button 308. Then, the enema liquid in the enema liquid storage cavity 7 is input into the enema intubation tube 203 by using the second liquid outlet pipe 303, so as to perform an enema cleaning operation on the patient with the enema liquid.
