Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of rectal analgesia devices for bowel sound monitoring, and particularly to a rectal analgesia device and system based on bowel sound monitoring. Background Art
[0002] Among surgical patients, due to factors such as surgery and anesthesia, gastrointestinal motility function will be weakened or even disappear. Therefore, most patients will experience temporary intestinal function disorders after surgery, such as paralytic ileus. Once paralytic ileus occurs, patients need to fast and refrain from drinking for a period of time, which is extremely unfavorable for the body's recovery. Research has found that paralytic ileus in patients after general anesthesia has a certain pattern: paralytic ileus is caused by general anesthetic drugs, especially opioid drugs, for a certain period after surgery. When opioid drugs are gradually excreted from the body, intestinal function gradually recovers, and at this time, the number of bowel sounds increases. Once the analgesic intensity decreases and the patient experiences obvious pain, paralytic ileus will occur again. Therefore, appropriate analgesia at a certain concentration after surgery is necessary; Most existing intestinal condition detection devices do not have detection equipment such as a pickup, or do not have a mechanism in which a program control module slot and an electronic signal transmission line cooperate with each other, making it difficult to detect the condition of the patient's intestine at all times. Only intermittent evaluations can be carried out, and the dynamic changes in the intestinal state cannot be captured in a timely manner; and existing rectal analgesia devices may not have a design in which an electronic infusion pump and a liquid suction needle tube cooperate with each other, making the process of sucking liquid medicine from the medicine injection bag slot not smooth enough, the operation is relatively complex, and the convenience of using intestinal liquid medicine is reduced; and existing rectal analgesia devices are difficult to meet the analgesia needs of patients at different stages after surgery, and it is easy to have the problem of untimely postoperative analgesia, bringing unnecessary pain to patients; Existing technologies simply rely on the presence or absence of bowel sounds to judge the intestinal condition, and the monitoring of bowel sounds is affected by other interfering sounds, making it impossible to comprehensively obtain the true state information of the intestine, resulting in inaccurate assessment of the patient's intestinal health status and affecting the pertinence and effectiveness of analgesic treatment;
