Medical decompression drainage device based on stomach intestine, pleuroperitoneal cavity and postoperative parts

Abstract

The invention provides a medical decompression drainage device based on stomach intestine, pleuroperitoneal cavity and postoperative parts. The medical decompression drainage device comprises a driving device, wherein the driving device is detachably arranged on a bracket body through a base and comprises a cylindrical casing, an inclined surface is formed on the top surface of the casing, and a control panel is arranged on the inclined surface; an elastic drainage device is detachably fixed to the bottom wall in the casing, a side door is arranged on the side, away from the bracket body, of the casing and serves as an entrance of the elastic drainage device; a stretching mechanism is arranged at the upper part in the casing, the lower end of the stretching mechanism is connected with theupper end of the elastic drainage device, the control panel controls the stretching mechanism to stretch the elastic drainage device, so that negative pressure is produced in the elastic drainage device, a constant negative pressure state is kept, and the risk of reflux infection is avoided. The decompression drainage device is safe, reliable and convenient to use, the amount of gas and fluid drained out of the body can be displayed on the control panel in real time, and reliable and accurate judgment basis is provided for medical effects.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a medical decompression drainage device based on gastrointestinal, thoracic and abdominal cavity, and postoperative parts. drainage. Background technique [0002] Generally speaking, fluid and gas will be produced in the patient's surgical site or gastrointestinal tract after surgery, and the gas and liquid accumulated in the patient's body need to be discharged in time to reduce the pressure in the gastrointestinal tract and postoperative wound and reduce the risk of complications. occur. [0003] Postoperative drainage is a common medical care technology, which uses the principle of negative pressure suction to discharge the gas and liquid accumulated in the patient's body through a drainage device. Patients with different types and different surgical sites have different postoperative drainage conditions. Some patients have more gas and liquid in their bodies, while ...

AI Technical Summary

Problems solved by technology

[0005] 1. The pressure of suction is not intuitive, and the pressure cannot be adjusted freely according to different types of patients;

[0006] 2. If the drainage pipe is bent, the drainage will be blocked and the drainage will not be smooth, which is not easy to be found, and may cause adverse consequences;

[0007] 3. The drainage tube in contact with the patient's skin and mucous membrane may cause the tube to cling to the mucous membrane wall due to the large negative pressure, resulting in local mucous membrane wall ischemia, necrosis, and mucous membrane wall damage;

[0008] 4. The drainage process requires continuous observation by medical staff or patients, and untimely observation may cause adverse consequences;

[0009] 5. When the drainage device is squeezed twice or multiple times, it may cause the drainage material to spill, reflux, and inconvenient operation, resulting in iatrogenic infection of patients, pollution of the medical environment, or occupational exposure or infection of medical staff. medical safety hazards;

[0010] 6. The gas and liquid from the drainage cannot be measured and the measurement is inaccurate, which affects the judgment and measurement of clinical treatment effect;

[0011] 7. The pressure generated by the drainage is uneven, for example: due to the action of the spring, the negative pressure gradually decreases when the compressed spring stretches until it returns to its original length

During this process, if more gas or liquid is produced, the effect and purpose of drainage will not be achieved due to the reduction of negative pressure
