Rapid blood transfusion apparatus

Abstract

The invention provides a rapid blood transfusion apparatus, which comprises a blood transfusion device, a blood anticoagulation device, a veinpuncture cannula and a three-way valve. The blood transfusion device and the blood anticoagulation device are the same in structure and respectively comprises a tube, a tube cap and a needle seat are arranged at two ends of each tube respectively, a flow control valve is arranged on each needle seat, a piston is arranged in a tube cavity of each tube, one end of a piston rod is fixed to each piston, the other end of each piston rod extends out of the corresponding tube cap, a telescopic spring is arranged between each piston and the corresponding tube cap, each piston is pushed towards the corresponding needle seat by the aid of the elastic force ofthe corresponding telescopic spring, and three joints of the three-way valve are communicated with the needle seat of the blood transfusion device, the needle seat of the blood anticoagulation deviceand the veinpuncture cannula respectively through medical rubber tubes. The telescopic springs among the pistons and the tube caps of the blood transfusion device and the blood anticoagulation devicecan constantly exert pressure to blood or liquid medicine in the corresponding tube cavities, and the blood transfusion device and the blood anticoagulation device can be placed optionally and horizontally, so that the rapid blood transfusion apparatus is more conveniently used for human blood transfusion during transfer, and safety of blood transfusion is improved.

Description

technical field [0001] The invention relates to a blood transfusion set, in particular to a rapid blood transfusion set. Background technique [0002] No matter in peacetime or on the battlefield, massive bleeding often occurs in the human body. When massive bleeding occurs, acute hemostasis and rapid blood volume replenishment are required to save the patient’s life. Rapid blood transfusion is a problem often encountered by medical workers, but the general rapid blood transfusion routine operation It is the staff who insert a large needle into the patient's slightly larger venous vessel, then dissolve the whole blood or blood components taken from the blood bank, squeeze the blood bag by hand, and artificially increase the pressure to quickly inject the blood into the human body. Adopt existing blood transfusion belt to carry out rapid blood transfusion, there are following problems: [0003] 1. In order to quickly transfuse the blood in the blood bag into the blood vessel...

AI Technical Summary

Problems solved by technology

[0003] 1. In order to quickly transfuse the blood in the blood bag into the blood vessels of the human body, the medical staff needs to constantly exert pressure on the blood bag, which not only increases the burden on the medical staff, but also is not convenient for rapid blood transfusion during the transfer of patients. Manually squeezing the blood bag cannot ensure that the blood in the blood bag is uniformly injected into the blood vessels of the human body, and the puncture needle is easily blocked by coagulated blood

[0004] 2. In the case of massive bleeding, the blood volume of the patient drops sharply, and the blood vessels of the whole body contract. The puncture can only be performed through the jugular vein, femoral vein and other large and deep veins. , it is easy to fall off in a hurry, which will delay the rescue time and affect the success rate of rescue

[0005] 3. Ordinary blood transfusion devices are not easy to fix because of the puncture needle, and the blood transfusion bag, connecting catheter, and puncture needle are easy to fall off under the action of external force, causing air to enter the blood vessel and cause air embolism, which is inconvenient for the evacuation of the wounded and sick
