Adaptive overflow prevention enema syringe

Abstract

The invention discloses an adaptive overflow prevention enema syringe. The adaptive overflow prevention enema syringe comprises a liquid containing bottle, an infusion tube and an anal tube, which are sequentially connected, wherein an air sac is arranged on the anal tube, an air pump used for aerating the air sac is connected onto the air sac, the air pump is connected with a microprocessor, a dripping speed regulation device is further arranged on the infusion tube, the dripping speed regulation device comprises a photoelectric sensor and idler wheel pressure devices, a Murphy dropper is arranged in the middle of the infusion tube, the photoelectric sensor is arranged on the Murphy dropper, the idler wheel pressure devices are arranged on the infusion tube, the photoelectric sensor outputs data to the microprocessor, and the microprocessor drives the idler wheel pressure devices through a stepper motor so as to regulate dripping speed of the infusion tube. According to the adaptive overflow prevention enema syringe, a controllable pressure sleeve sac is added on the anal tube, the controllable pressure sleeve sac can seal an anus after the controllable pressure sleeve is aerated, and the problem that infusion liquid leaks is solved. The adaptive overflow prevention enema syringe can control intestine irrigation speed, controls a pair of the idler wheel pressure devices driven by the stepper motor through the microprocessor, and thereby can keep running stable.

Description

Technical field [0001] The invention relates to medical equipment, in particular to an adaptive anti-overflow enema. Background technique [0002] Patients with malignant tumors often have decreased appetite, dysphagia, nausea and vomiting, and low food intake. At the same time, to strengthen nutrition, they often consume fine foods with low fiber and high protein, lacking residues, and weaken the intestinal mucosal stimulation that causes defecation reflex. Due to the long time in bed, some patients take in too little water, and the feces cannot be softened enough to be discharged. According to statistics, more than 70% of cancer patients will eventually suffer from moderate or severe pain and require treatment with analgesics. However, analgesic drugs have an inhibitory effect on intestinal peristalsis, which slows down the movement of food in the intestine, and the water in the food is absorbed in a large amount, causing varying degrees of constipation. Especially for opioid...

AI Technical Summary

Problems solved by technology

[0003] The length of the anal canal inserted into the anus in the traditional enema method is 7-10 cm, while the length of the normal adult rectum is 12-15 cm. The front end of the anal canal can only reach the upper rectum. When the enema liquid flows out, it will cause mechanical and chemical stimulation to the rectal wall. When the enema fluid accumulates in the rectum by 150-200ml and the pressure reaches 7.3KPa, the receptors on the rectal wall will be strongly excited, and a strong desire to defecate will be generated through the nerve reflex. In addition, most tumor patients have poor coordination of the internal and external sphincters, and the phenomenon of outflow while irrigation often occurs , resulting in less infusion volume and short retention time, which cannot fully soften the stool and affect the effect of the enema
