Description

Disposable gastric lavage device

technical field

The present invention relates to the field of containers specially used for medical or medicinal purposes, in particular to a disposable gastric lavage device.

Background technique

Clinically, gastric lavage for patients with poisoning poisoning Most hospitals use gastric lavage machines for gastric lavage, but after all poisoned patients arrive at the hospital, first of all, there are many gastric lavage patients admitted to the emergency department every day, but due to the limited number of gastric lavage machines, The cleaning and disinfection process is time-consuming. When there are multiple gastric lavage patients at the same time, it is necessary to wait or use a syringe to complete the flushing and suction. Especially when poisoning by organophosphorus and other poisons, the gastric lavage volume needs to reach tens of thousands of milliliters at a time. The effluent is clear, transparent, and has no peculiar smell.

However, the internal pipeline of the gastric lavage machine currently used in clinical practice is complicated. After the gastric lavage, the nurse needs to strictly follow the disinfection process of the manual to sterilize it, so that it can achieve the purpose of completely killing bacteria. To prevent the poison from being further absorbed, the rescue work must be carried out against the clock. If there is no time condition, first check whether the patient has hepatitis, AIDS, syphilis and other pathogens and other related infections, and then distinguish the gastric lavage machine, and the internal pipeline of the gastric lavage machine. It is complicated, and the cleaning work after use is worrying. In clinical practice, it can only be cleaned and disinfected in strict accordance with the instructions of the gastric lavage machine, but it can achieve the purpose of completely killing pathogens and other poisons, which is impossible to verify. And whether the compliance and safety awareness of nurses can achieve strict disinfection of gastric lavage machines to ensure the safety of gastric lavage patients, it cannot be guaranteed, resulting in certain safety hazards for gastric lavage patients in clinical practice.

For example, Chinese Patent Application No. 2006200101107 discloses a simple gastric lavage device, which consists of a gastric lavage part, a venom extraction part and a gastric catheter, the gastric lavage part is a liquid storage bottle, and the venom extraction part is a negative pressure bottle and the gastric guiding tube is respectively connected with the liquid storage bottle and the negative pressure bottle through a three-pronged connecting tube, and a conducting valve is respectively provided between the three-pronged connecting tube, the liquid storage bottle and the negative pressure bottle. The device has a simple structure and can solve the first aid for digestive tract poisoning in remote areas. However, the device cannot effectively control the flow rate of gastric lavage liquid, and is likely to cause an increase in the intragastric pressure of the patient during the gastric lavage process, resulting in an uncomfortable reaction.

SUMMARY OF THE INVENTION

The purpose of the present invention is to provide a disposable gastric lavage device to solve the problems posed by the above-mentioned background art.

In order to achieve the above purpose, the following technical solutions are adopted:

Disposable gastric lavage device, comprising a liquid inlet tube, a liquid inlet balloon, a first clip, a second clip, a liquid discharge tube, a liquid discharge balloon, and a gastric tube connector, the liquid inlet tube is connected to the liquid inlet through the first clip In the balloon, the inlet balloon is connected to the gastric tube joint through the second clip, the other end of the drainage tube is connected to the drainage balloon through the first clip, the drainage balloon is connected to the gastric tube joint through the second clip, and the whole device is formed. A three-way structure centered on the gastric tube.

In a further improvement, the capacity of each infusion balloon or drainage balloon is 500ml, and the balloon has a scale of 100-500ml, which can control the amount of liquid injected into the stomach to reach 250-300ml at one time.

Further improvement, the inflow and outflow balloons are controlled by a complete set of electronic equipment, and the inflow and outflow flow is adjusted according to the pressure of the contents in the patient's stomach to ensure the dynamic balance of the pressure in the patient's stomach; A pressure sensor for monitoring the liquid state is set at the position of the pipe joint, and a flow regulating electromagnetic valve is set at the position of the liquid inlet balloon and the liquid discharge balloon. The whole set of equipment is powered by a driving motor or a small battery.

The beneficial effects of the present invention are as follows: it can be ensured that gastric lavage treatment can be completed even if multiple patients are simultaneously performed, and there is no problem of disinfection after use, and the complete set of devices can be treated strictly according to medical waste, which not only ensures the safety of patients, It also minimizes the occurrence of cross-infection. Satisfy the operation of gastric lavage for multiple patients at the same time; the operation is simple, easy to learn, and easy to use; in this way, gastric lavage can effectively control the balance of liquid volume in and out of the stomach through the balloon, ensure the safety of patients, and prevent excessive storage in the stomach. discomfort or injury.
