Intelligent flushing and low-negative-pressure drainage device for medical three-cavity drainage tube

Abstract

The invention discloses an intelligent flushing and low-negative-pressure drainage device for a medical three-cavity drainage tube, and relates to the technical field of medical auxiliary equipment, the intelligent flushing and low-negative-pressure drainage device comprises a negative pressure mechanism, a drainage assembly and a flushing assembly, the output end of the negative pressure mechanism is connected with a negative pressure tube, and the tail end of the negative pressure tube extends to be connected with the drainage assembly; the drainage assembly comprises a drainage bottle and a negative pressure adjusting mechanism arranged at the bottle opening end. The drainage assembly further comprises a first drainage tube, one end of the first drainage tube extends and is connected into the drainage bottle, and the first drainage tube is used for pressing the flushing liquid into the drainage bottle under the action of pressure; the flushing assembly comprises a flushing fluid bag arranged on one side of the drainage bottle, and the bottom side of the flushing fluid bag is connected with a flushing pipe. The negative pressure adjusting mechanism is used for adjusting the pressure applied to the drainage bottle by the negative pressure mechanism, so that the stability is higher in the process of low-negative-pressure suction and drainage when the medical personnel perform peritoneal irrigation treatment on the patient.

Description

technical field [0001] The invention relates to the technical field of medical auxiliary equipment, in particular to an intelligent flushing and low negative pressure drainage device for a medical three-cavity drainage tube. Background technique [0002] Irrigation of the abdominal cavity and low negative pressure suction and drainage are the keys to controlling infection in some abdominal surgery patients. Some patients after abdominal surgery are often left with one or more three-lumen drainage tubes in the abdomen for irrigation and drainage, effective irrigation and low negative pressure. Pressure suction drainage can remove ascites, exudate and necrotic tissue, etc., to avoid or reduce the occurrence of infection. [0003] In clinical practice, because the central negative pressure system uniformly configured in the hospital cannot be accurately adjusted to a lower negative pressure value, a negative pressure regulating bottle that can achieve lower negative pressure su...

AI Technical Summary

Problems solved by technology

[0003] In clinical practice, because the central negative pressure system uniformly configured by the hospital cannot be accurately adjusted to a lower negative pressure value, a negative pressure adjustment bottle that can achieve lower negative pressure suction is connected in series during peritoneal irrigation and drainage, which wastes consumables and is cumbersome to operate. Occupying space, peritoneal flushing usually uses normal saline connected to the infusion set for continuous flushing, and the drip rate is manually adjusted according to the situation. The flushing speed is not easy to control, and there are often errors, and the flushed volume cannot be calculated in real time. Some hypothermic patients use a large amount of normal temperature normal saline When flushing, hypothermia will be aggravated, and severe hypothermia will lead to death. In this case, it is necessary to heat the flushing liquid, which can increase the body temperature of the patient while flushing. The medical staff cannot patrol in time due to busy work and other reasons. If the low negative pressure drainage tube is unsmooth or blocked and cannot be known and dealt with in time, it will affect the flushing and drainage effect, and the amount of liquid drained out will often have measurement errors due to various reasons. When the bloody liquid in the drainage tube is drawn out and reaches a certain concentration, Prompt abdominal bleeding, the bloody liquid detection device can prompt and alarm, so that medical staff can detect and deal with changes in the condition in time
