Intelligent stomach lavage instrument applicable to medical emergency department

Abstract

The invention belongs to the technical field of medical apparatus and instruments, and in particular relates to an intelligent stomach lavage instrument applicable to the medical emergency department.The intelligent stomach lavage instrument comprises an outer tube, an inner tube, a support frame, a pressure control module, a double-head motor, a liquid inlet pump, a liquid outlet pump, a lavageliquid bottle, a recycling bottle, one-way valves and a control box, wherein the inner tube is positioned inside the outer tube, and the support frame is arranged on the outer wall of the inner tube;a liquid inlet is formed in the side wall of the outer tube, and the outer tube is used for injecting washing liquid to the stomach; the pressure control module is used for adjusting the pressure of the washing liquid entering the stomach; the double-head motor is used for driving the liquid inlet pump and the liquid outlet pump to simultaneously work; the liquid inlet pump is used for injecting the washing liquid to the inside of the outer tube through the liquid inlet; the liquid outlet pump is used for pumping out the liquid in the stomach through the inner tube, and both the liquid inlet pump and the liquid outlet pump are connected with the one-way valves; the control box is used for controlling the work of the stomach lavage machine. With the intelligent stomach lavage instrument applicable to the medical emergency department, the change of the stomach can be automatically detected in real time, bleeding detection also can be realized, thus the liquid feeding amount can be accurately adjusted, the pressure of the stomach can be controlled, and therefore, the secondary injuries caused to the stomach are avoided.

Description

technical field [0001] The invention belongs to the technical field of medical equipment, in particular to an intelligent gastric lavage instrument suitable for medical emergency departments. Background technique [0002] For patients with food poisoning, poisoning, and people who need gastric lavage before surgery, hospitals, emergency centers, etc. often use gastric lavage machines to perform gastric lavage on patients. Before gastric lavage, it is necessary to prepare and adjust the equipment to normal. When in use, the contents of the stomach need to be pumped out first, press the "automatic control" working switch, the machine will enter the automatic gastric lavage process, if there are no special circumstances, the gastric lavage work can be completed without manual operation, and gastric lavage can also be performed by manual control. [0003] As we all know, the primary procedure of first aid for poisoned patients is to remove poison, and for patients with oral poi...

AI Technical Summary

Problems solved by technology

[0003] As we all know, the primary procedure of first aid for poisoned patients is to remove poison, and for patients with oral poisoning, firstly, they must be treated with vomiting or gastric lavage. In the past, gastric lavage was performed manually. After the gastric lavage machine, its advantages such as saving time and labor have reduced the intensity of clinical nursing work, and shortening the time for gastric lavage has also brought good news to patients. However, the pressure setting, liquid delivery and The conversion of the liquid is controlled by humans. It will deliver liquid to the patient in a short time, at a high speed, and at a large flow rate. Repeated flushing of the high-pressure water for a long time can lead to gastric mucosal hyperemia, ulcer bleeding, and gastric perforation and gastric rupture. Waiting for the occurrence of secondary lesions, which virtually puts forward higher requirements for doctors' operating skills and increases the work pressure of doctors; at the same time, it also makes it difficult for patients' health to be effectively guaranteed
