Device capable of automatically controlling drainage volume

Abstract

The invention provides a device capable of automatically controlling drainage volume which can be connected to wound or body cavity effusion drainage tubes such as urinary vessels, abdominal dropsy drainage tubes, closed thoracic drainage tubes, pericardial catheter drainage tubes, ventricular drainage tubes, T drainage tubes, and fistula drainage tubes to realize draining and flushing and especially for the condition that there may be leakage of cerebrospinal of spinal postoperation incision. By means of the automatic drainage volume control device, the drainage tubes can be automatically clipped and closed after the preset drainage volume is reached; at the same time, the negative pressure of the drainage device can be regulated and monitored to realize accurate drainage to avoid complications due to excessive or insufficient drainage and be helpful for the healing of wounds.

Description

technical field [0001] The invention belongs to the field of medical equipment, and in particular relates to a device capable of automatically controlling drainage volume. Background technique [0002] External drainage of effusion is a drainage method commonly used in clinical practice. It puts one or more porous catheters connected to the drainage bag into the wound cavity or body cavity, and the effusion in the cavity is automatically led out into the drainage bag, which can prevent infection and relieve the adjacency. Compression of organs and tissues improves symptoms and can promote wound healing. According to clinical experience and a large number of literature searches, it is shown that intermittent and quantitative drainage are very important in the process of drainage of effusion. For example, rapid drainage of a large amount of pleural effusion can lead to reexpansion pulmonary edema and mediastinal oscillation, and excessive drainage of peritoneal effusion can l...

AI Technical Summary

Problems solved by technology

[0004] 1. The daily drainage volume cannot be automatically controlled. At the same time, since the drainage bag must be hung at a low place, it is difficult to observe

It causes excessive tension among medical staff, patients and family members. Medical staff need to check the drainage volume irregularly and repeatedly, and then clamp it manually after reaching a certain amount, which is very time-consuming and energy-intensive.

[0005] 2. If the postoperative wound or effusion in the cavity is infected, it cannot be rinsed and drained in time with a single tube. Once the local infection of the wound cannot be controlled, the infection will spread and spread to adjacent tissues and organs

[0006] 3. It is impossible to detect the negative pressure of the drainage device, which may easily lead to excessive or insufficient drainage speed and cause corresponding complications
