It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0019] In order to illustrate the technical solution described in the present utility model, the following will be described through specific embodiments.

[0020] Only the parts related to the embodiments of the present utility model are shown for the convenience of description.

[0021] Combined with Figures 1-3 As shown, this blood transfusion and infusion warming and pressurizing instrument includes a main unit 1. Inside the main unit 1, there are arranged a main control board 2, an air pump 3 and a pressure relief valve 4. A pressure sensor is arranged on the main control board 2. The warming and pressurizing instrument also includes a pressurizing bag 6 and a heating tube 7. The air pump 3 is connected to the pressurizing bag 6, the pressure relief valve 4 and the pressure sensor through a pipeline 8. The heating tube 7 is electrically connected to the main unit 1. A housing 9 is installed on the main unit 1, and a cover body 10 is covered on the housing 9. A motor 11 is installed inside the housing 9. A rotating arm 12 is connected to the output shaft of the motor 11. There is a movable groove one 1001 inside the cover body 10.

There are several symmetrical clamping blocks 21 on both sides of the tube slot 1002. The housing is connected to the main body through the insertion strip and slot mechanism, which is convenient for installation and disassembly. Both ends of the movable plate can move along the second movable slots. By moving the cover plate on the movable plate to the tube slot, the tube slot can be covered, which also protects the blood transfusion or infusion tube in the tube slot. The clamping blocks in the tube slot are used to clamp the blood transfusion and infusion tube to ensure that the blood transfusion or infusion tube can be stably installed in the tube slot.

[0025] In summary, the present utility model provides a blood transfusion and infusion warming and pressurizing instrument. The blood transfusion and infusion warming and pressurizing instrument is provided with a heating tube for heating the blood transfusion or infusion tube and a pressurizing bag for pressurizing the blood transfusion or infusion tube, realizing convenient adjustment of the temperature and pressure of blood transfusion or infusion. The composition of the blood transfusion and infusion warming and pressurizing instrument is relatively simple, and the production and use costs are relatively low. The motor on the blood transfusion and infusion warming and pressurizing instrument drives the pressing plate to move in the first movable slot through the connecting arm. The tube pressing part on the pressing plate extends into the tube slot and squeezes the blood transfusion or infusion tube. The operator can operate the motor to change the depth of the tube pressing part squeezing the blood transfusion or infusion tube, thereby changing the speed of blood transfusion or infusion, providing convenience for the treatment of patients.
