Description

Glycerine enema injection device

Technical Field

The utility model belongs to the technical field of medical instrument, concretely relates to glycerine enema injection device.

Background

Constipation refers to the accumulation of toxins, dry and hard stools, difficult defecation or reduced defecation frequency of stools when the stools stay in the intestinal cavity for too long. Many elderly patients are in bed for rest, lie in bed for a long time, have weakened gastrointestinal motility, change life style and defecation style, and are easy to cause constipation due to anxiety and the like. According to statistics, 50-70% of orthopedic patients can suffer from constipation. The metabolites in the body of a patient with constipation cannot be discharged out of the body in time, and enterotoxin is absorbed, so that symptoms such as general malaise, dysphoria, nausea, vomiting, abdominal distension, appetite reduction, insomnia and the like can appear, the life quality and rehabilitation training of the patient are seriously affected, anal diseases such as anal fissure and hemorrhoids or deep venous thrombosis shedding, syncope, cerebrovascular accidents, myocardial infarction and even death can also occur due to forced defecation. Once constipation occurs, the patients suffer great pain, and the constipation has great influence on the body and mind of the patients, so that the constipation becomes one of the problems which are generally concerned in clinical care. At present, the constipation is treated temporarily by adjusting the diet, externally using a lubricant or an enema, taking various laxative drugs and the like in China, and the constipation is aggravated because the long-term application causes the tolerance to the laxative, the enterokinesia reaction is reduced, the tension of the intestinal tract is lost, the autonomous defecation reflex is weakened; improper administration of cathartic also can cause abdominal pain, diarrhea, and adverse reactions such as water electrolyte and acid-base imbalance. How to reduce the incidence rate of constipation of a patient lying in bed and promote the early recovery of the patient is a clinical problem to be solved.

The defecation reflex is completed by nerves of the ampulla of the rectum, the distance of the ampulla of the rectum can reach 7cm furthest, the length of the thin end of the enema is only 3cm, the enema which is squeezed into the anus by a conventional method can only reach the anal canal, the stimulation effect on the rectum is small, the defecation reflex is relatively weak, and the effect on a patient with small dry stool is very weak or even ineffective.
