Anti-return blood infusion device to solve the problem of blood return
In the past, in the process of infusion, patients and medical staff always watched carefully whether the liquid was about to be lost. Once the medical staff is negligent, the patient is in a sleep state, the drug solution is lost, and the needle is not pulled out in time, which will cause the patient to bleed. Recently, a clever small invention of Shenzhen Convair Technology Co., Ltd. has solved the problems inherent in the use of a hundred-year drop tube. A “anti-return blood infusion device” with independent intellectual property rights has brought about revolutionary innovation.
Wei Yingde, the inventor of the anti-return blood infusion device, introduced that the drip-speed display tube (also known as the Mofite dropper) on the disposable infusion set was invented by Europeans more than 100 years ago and has been used all over the world until now. Due to lack of design or limitations, it is highly prone to problems such as blood return, air entering the vein, and thrombosis.
The "anti-return blood infusion set" differs from the conventional infusion set in that a pressurized balloon and piston are added to the inside and below of the Mohler dropper. When infusion, when the liquid enters the dropper, the piston floats and the liquid enters the infusion tube into the human body like a conventional infusion set. When the liquid is nearly dripped, the liquid level in the dropper gradually drops, and the piston sinks down, completely blocking the dropper outlet. At this point, the outlet to the needle is filled with liquid, which can overcome the venous pressure and prevent blood return.
According to Wei Yingde, according to incomplete statistics, disposable infusion sets are about 10 billion yuan a year, and the world needs about 60 billion. The market is huge. And their researchers have gone through thousands of experiments, improvements and clinical trials and trials, making the "anti-return blood disposable infusion set" simple in structure, the production cost is basically the same as the currently used disposable infusion device, and it can be matched with it. In the case of functions, the production cost has not increased much, so it is very competitive, and its potential economic and social benefits are enormous.
