In hospital blood banks, some blood products are stored at temperatures below 4 ℃. Therefore, after removal from the freezer, the blood product in the blood bag can reach room temperature of 15℃, but is still well below 37℃ of the normal body temperature of a human body. When a large amount of low-temperature liquid is input into a human body in emergency treatment and operation for mass blood transfusion, the body temperature of a patient is reduced, so that the normal temperature of enzyme reaction in the human body is changed, enzymatic biochemical reaction of the whole body is seriously influenced, and the life function is threatened. Meanwhile, the patient is frigid due to temperature loss, metabolizes at a high speed, and threatens the life of the patient, so that the massive infusion of unheated blood products can cause great danger for rescue work.

In addition, blood products which are not heated enter blood vessels, so that the smooth muscles of the blood vessels can be spontaneously contracted, the blood vessels become thin, resistance is increased, the transfusion is blocked smoothly, and pain is increased for patients.

However, this extensive practice has significant disadvantages. Firstly, a bag of blood generally takes 1 to 2 hours to transfuse, and the temperature of the hot towel is very fast reduced, and the temperature is kept for ten minutes at most. The remaining time is difficult to ensure the continuous temperature of the transfusion, so that adverse reactions of condensation collection in the blood inevitably occur. Secondly, the hot towel at 50 ℃ directly heats the blood vessels under the skin, and above 38 ℃ there is a risk of damage to the erythrocytes, which can cause hemolysis. Therefore, this infusion method is troublesome to operate, inefficient, uncontrollable in temperature and speed, and dangerous to a certain extent.

Therefore, it is necessary to provide a technical solution that can increase the temperature during blood transfusion and improve the convenience of transfusion.

Detailed Description

The following describes in detail embodiments of the present invention with reference to the accompanying drawings. It should be understood that the description herein is provided for illustration and explanation of the invention and is not intended to limit the invention.

The utility model provides a blood transfusion box container with temperature and speed control, which aims to solve the problems that the temperature and the speed are difficult to control, inconvenient and have certain danger when the existing blood products are transfused.

Referring to fig. 1-4, to achieve the above object, the present invention provides a temperature and speed controlled transfusion box container, which comprises a box body 100 and a box cover 107; the box cover 107 is rotatably arranged on the box body 100 around a predetermined rotating shaft and can be buckled on the box body 100, so that the box cover 107 is closed, and the heating work in the box body 100 is stably carried out; the size of the box 100 can be 30X 15X 8 cm, but the specific size can be specifically set according to the actual situation so as to be able to properly place the blood bag 121. The hook 104 is arranged on the top surface in the box body 100, the blood bag 121 is hung at the hook 104, so that the blood bag 121 is flatly placed in the box body 100, and the surface of the hook 104 is oily and smooth, so that the blood bag 121 cannot be scratched.

Wherein, be provided with electric blanket 106 on at least one wall in box body 100, in this embodiment, electric blanket 106 has all been laid to the bottom surface and four lateral wall faces in box body 100 inside, produces heat through electric blanket 106 to heat blood, blood products in the blood bag 121, thereby let blood reach predetermined temperature, thereby solve the adverse reaction that blood low temperature infusion brought, guarantee patient's life safety.

A pressure pump 102, an electronic scale 101 and an air bag 103 are arranged in the box body 100; an electronic scale 101 is installed above the case body 100, a pressure pump 102 is installed at the upper end of the case body 100, and an air bag 103 is installed in the case body 100 on the wall surface of the case body 100 opposite to the case cover 107. Further, the electronic scale 101 is provided with a hook, so that the box 100 is hung on the liquid replenishing rack; a control chip is arranged in the electronic scale 101; the control chip is electrically connected with the pressure pump 102, and the pressure pump 102 is connected with the air bag 103. The electronic scale 101 can dynamically measure the weight of the blood transfusion box, the pressure pump 102 is used for providing gas for the air bag 103 to inflate and expand the air bag 103, so that the air bag 103 is flatly pressed on the blood bag 121, blood products in the bag flow out to realize transfusion, and the pressing force on the blood bag 121 can be adjusted by changing the pressure of the air bag 103, so that the blood transfusion speed of the blood bag 121 is changed. Specifically, during infusion, the weight of the blood bag 121 changes, and the electronic scale 101 can obtain the weight change through measurement, so as to determine the infusion speed, such as: the normal speed of transfusion is 2 ml to 3 ml per minute, that is, the whole weight of the transfusion box is reduced by 2 to 3 g per minute, when the electronic scale 101 detects the total weight of the electronic scale per 30 seconds, if the total weight of the transfusion box is reduced too fast, the transfusion speed is too fast, then the control chip controls the pressure pump 102 to stop, so as to reduce the pressure of the air bag 103 on the blood bag 121, thereby slowing down the transfusion speed; if the total weight is reduced too slowly, which means the transfusion speed is too slow, the control chip controls the pressure pump 102 to inflate the air bag 103, so as to inflate the air bag 103, thereby increasing the squeezing of the blood bag 121 and accelerating the transfusion speed.

In one embodiment, a safety valve is provided within the cartridge 100; a safety valve is connected to the pressure pump 102, wherein the safety valve is used for alarm purposes.
