Description
Technical Field
The utility model relates to the technical field of medical equipment is relevant, concretely relates to anti-reflux stoma enema device.
Background
The stoma is caused by diseases of digestive system or urinary system, and the intestinal canal needs to be separated through surgical treatment, and one end of the intestinal canal is led out to the body surface (anus or urethra is moved to abdominal wall) to form an opening. The stoma is generally directed to a lesion of the rectum and bladder (e.g., rectal cancer, bladder cancer, ileus, etc.), and in order to maintain the patient's life, a doctor surgically removes the lesion, for example, rectal cancer removes the rectum and anal canal, bladder cancer removes the bladder, and then opens an opening on the left or right side of the patient's abdomen. Stool or urine is involuntarily expelled through the stoma, and such patients will need to stick a bag at the stoma to contain the expelled contents after discharge.
In the clinical nursing working process, when a medical worker washes an enterostomy for a patient with the enterostomy, the medical worker generally adopts a common enemator to carry out washing operation, the common enemator generally comprises a liquid storage washing bag, a catheter and a flow rate regulating block, the catheter is a soft tube body, when the enemator is used, the medical worker is not convenient to insert into the enterostomy of the patient, and the soft catheter is easy to slip out of the enterostomy in the process of washing the enterostomy to cause the failure of the washing operation; because the stoma is not provided with the sphincter like an anus, the enema is very easy to flow back out of the stoma and lose the treatment effect during enema; some drainage tubes are easy to block in the process of flushing the intestinal tract of a patient; some patients have thin intestinal tracts and are inconvenient to put in a drainage tube; some patients are in drainage liquid flushing process, excrement and urine can be followed stoma department blowout etc. these all increase medical personnel's the work degree of difficulty and work load, have great use limitation in the in-service use process. Related designs can be found in chinese patents 201520632860.7, 201720352306.2, 201920800222.X, etc.
