[0029] like Figures 1 to 8As shown, the heatable and pressurized device for blood transfusion in the hematology department of this embodiment comprises a box body 1, two hinged frames 3 are arranged at the edges of both sides of the box body 1, and the tops of the two hinged frames 3 are hingedly installed with covers 4. When the two covers 4 are closed, the top of the box body 1 is sealed, so that the inside of the box body 1 is in a relatively sealed state, which is convenient for heating the blood bag. Two heating components 9 are arranged on both sides of the box body 1, wherein a temperature sensor 2 is arranged at the front end of the box body 1 between the two heating components 9, flexible nets 10 are arranged at opposite ends on both sides of the inside of the box body 1, vertical shafts 12 are arranged inside the two flexible nets 10, and the bottoms of the two vertical shafts 12 extend out of the bottom of the box body 1, and the outer surfaces of the two vertical shafts 12 inside the box body 1 are equidistantly provided with a plurality of toggles 11, and the two vertical shafts 12 are arranged at the same distance. The extending ends are both provided with forward and reverse motors 14. When the blood bag is pressurized and heated, the blood bag is placed between the two flexible nets 10, and then the two forward and reverse motors 14 respectively drive the corresponding vertical shafts 12 to perform reciprocating rotational motion, so that the two ends of the toggle 11 are respectively pushed back and forth toward the two sides of the blood bag, so that the blood inside the blood bag is squeezed and shaken continuously to avoid stratification. The outer surfaces of the two forward and reverse motors 14 are both provided with sliding brackets 13, and the bottom end of the box body 1 is provided with two limiting grooves 16, which match the sliding brackets 13. The two sliding brackets 13 support the forward and reverse motors 14 respectively, and at the same time, the two limiting grooves 16 limit the sliding brackets 13, so that the two forward and reverse motors 14 can perform relative linear motion, and the box body 1 A driver 15 is installed on the outer surface of the vertical shaft 12 between the bottom end and the sliding bracket 13 through a bearing. The opposite ends of the two drivers 15 are meshed and connected with a gear 19. A driving motor 18 is arranged at the middle position of the bottom end of the gear 19. The driving motor 18 includes a locking component. When the top gear 19 of the driving motor 18 rotates to a certain number of circles, the locking component locks the output shaft of the driving motor 18 so that it does not rotate. The output shaft of the driving motor 18 can drive the gear 19 to rotate. When the gear 19 rotates, it will drive the two drivers 15 to perform relative linear motion to pull the two vertical shafts 12 to move in the direction of the blood bag. The blood bag is pressurized by a plurality of toggles 11 and two flexible nets 10. Cavities 2 are arranged inside both sides of the box body 1. 3. A blocking plate 22 is hingedly installed inside the cavity 23. The bottom of both sides of the box body 1 is provided with a first exhaust port 6. A second exhaust port 24 is provided at the bottom of the box body 1 corresponding to the first exhaust port 6. When the two heating components 9 heat the inside of the box body 1, the temperature inside the box body 1 is monitored by the temperature sensor 2. If the temperature sensor 2 detects that the temperature inside the box body 1 is too high and may affect the blood activity, the blocking plate 22 is driven to flip so that the second exhaust port 24 is connected to the first exhaust port 6. Since the ambient air temperature is lower than the air inside the box body 1, the hotter air inside the box body 1 will be discharged through the second exhaust port 24 and the first exhaust port 6, so that the temperature inside the box body 1 is reduced. When the temperature inside the box body 1 is reduced to a suitable temperature,The blocking plate 22 is driven to flip and block the second exhaust port 24 and the first exhaust port 6, so as to prevent the hot air inside the box body 1 from continuing to be discharged, thereby maintaining the temperature inside the box body 1.

[0030] Specifically, a pipe opening 8 is provided at one edge of the top of each of the two covers 4, and the two pipe openings 8 are combined into a cylindrical shape. When the two covers 4 are closed, the two pipe openings 8 clamp the discharge hose of the blood bag to reinforce the blood bag and avoid dislocation of the blood bag when the blood bag is pressurized.

[0031] Furthermore, portable handles 5 are hingedly installed on both sides of the upper part of the box body 1. If it is necessary to carry or take the heatable and pressurized device for blood transfusion in the hematology department, the portable handles 5 can be flipped upward so that the portable handles 5 are facing upward, which is convenient for carrying the heatable and pressurized device for blood transfusion in the hematology department.

[0032] Furthermore, a positioning plate 20 is provided at the top of each of the two drivers 15, and two long grooves 21 matching the positioning plate 20 are provided at the bottom of the box body 1 between the two limiting grooves 16. The two long grooves 21 limit the corresponding drivers 15 through the positioning plate 20 to ensure that the drivers 15 can perform linear motion without deflection.

[0033] Furthermore, a fixed bracket 17 is provided on the outer surface of the driving motor 18, and the top of the fixed bracket 17 is installed together at the bottom of the box body 1. A base 7 is provided at the bottom of the box body 1. The base 7 is a square component with a hollow interior. The power supply component, temperature control component, control circuit component, etc. are all installed inside the base 7, and a control panel can be installed on the surface of the base 7 for use. The fixed bracket 17 supports the driving motor 18 so that the driving motor 18 has a smaller shaking amplitude when running. The base 7 protects the parts located at the bottom of the box body 1, thereby improving the firmness of the heatable and pressurized device for blood transfusion in the hematology department.

[0034] Furthermore, a semicircular toothed disc 25 is provided on the top of each of the two blocking plates 22, and a rack 26 is meshed and connected to the top of the semicircular toothed disc 25. An electric push rod 27 is provided at one end of the rack 26. The electric push rod 27 drives the rack 26 to perform linear motion. When the rack 26 performs linear motion, it will drive the semicircular toothed disc 25 to perform rotational motion, so that the blocking plate 22 is flipped.

[0035] Furthermore, the toggle device 11 includes a support plate 1103, a support rod 1101 and a toggle ball 1102. There are two support rods 1101 and two toggle balls 1102. The support plate 1103 is connected to the vertical shaft 12. The two support rods 1101 are located on both sides of the support plate 1103. The two toggle balls 1102 are respectively located at one end of the support rod 1101. When the toggle ball 1102 is driven by the vertical shaft 12 to perform reciprocating motion, the vertical shaft 12 drives the toggle ball 1102 to continuously reciprocate and squeeze the blood bag, pressurizing the blood bag while causing the blood inside the blood bag to be toggled to cause disorder, thereby avoiding stratification.

[0036] Furthermore, the four heating components 9 and the temperature sensor 2 are all extended into the interior of the box body 1, so that the heating component 9 can heat the interior of the box body 1 easily. The extended end of the temperature sensor 2 is a monitoring component to ensure the monitoring accuracy.

[0037] The method of use of this embodiment is as follows: when using the heated and pressurized device for blood transfusion in the hematology department, the two covers 4 are opened, and then the blood bag output tube is placed upward between the two flexible nets 10 inside the box body 1, and then the two covers 4 are closed to clamp the output hose in the middle through the two pipe openings 8 to reinforce the blood bag, so that the inside of the box body 1 is in a relatively sealed state, which is convenient for heating the blood bag. The two heating components 9 heat the inside of the box body 1, and the temperature sensor 2 detects the temperature inside the box body 1. If the temperature sensor 2 detects that the temperature inside the box body 1 is too high and may affect the blood activity, the blocking plate 22 is driven to flip to connect the second exhaust port 24 and the first exhaust port 6. Since the ambient air temperature is lower than the air inside the box body 1, the hotter air inside the box body 1 will be discharged through the second exhaust port 24 and the first exhaust port 6 to reduce the temperature inside the box body 1. When the temperature drops to a suitable temperature, the blocking plate 22 is driven to flip and block the second exhaust port 24 and the first exhaust port 6 to prevent the hotter air inside the box body 1 from continuing to be discharged, thereby maintaining the temperature inside the box body 1. When the temperature of the blood inside the blood bag is suitable, the gear 19 is driven to rotate by the driving motor 18. When the gear 19 rotates, it will drive the two drivers 15 to perform relative linear motion to pull the two vertical shafts 12 to move toward the blood bag. The blood bag is pressurized by a plurality of toggles 11 and two flexible nets 10, so that the blood is squeezed from the inside of the blood bag and discharged from the output hose. When the blood bag is pressurized, the corresponding vertical shafts 12 are driven to perform reciprocating rotational motion by two forward and reverse motors 14, so that the two ends of the toggles 11 are pushed back and forth toward the two sides of the blood bag, so that the blood inside the blood bag is squeezed and shaken continuously, so that the blood is heated more evenly to avoid stratification.

[0038] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
