Description

Technical Field

[0001] This invention relates to the field of blood storage technology, specifically to a blood storage device for hematology. Background Technology

[0002] When donating or collecting blood outside, blood needs to be temporarily preserved and transported. This is important for the subsequent identification or application of the blood. However, current blood transport boxes generally just put the blood collection tubes and blood bags inside and leave them alone. Over time, the blood is prone to clotting.

[0003] To this end, Chinese Patent Publication No. CN209871064U discloses "A Blood Storage Device for Hematology Departments," the main structure of which includes a storage box with a hinged side door on one side of the opening. A motor bracket is fixed to one side of the bottom of the storage box, and a motor is fixed to the upper side of the motor bracket. The output shaft of the motor is fixedly connected to one end of an L-shaped rod, and the other end of the L-shaped rod is fixedly connected to a cylindrical slider. The cylindrical slider is embedded in a groove of a straight groove rod, and a cylinder is hinged to the lower middle part of the straight groove rod. The cylinder is fixed to one side of the motor bracket. The upper part of the straight groove rod is fixedly connected to the upper side of the storage tank. In this blood storage device, the blood bag is placed in the storage tank, the side door is closed, and the second limiting block is between the two first limiting blocks. The pin is passed through the center hole of the first limiting block and the second limiting block. The switch is turned on, the motor starts, and the output shaft of the motor rotates, driving the L-shaped rod fixedly connected to it to rotate. The L-shaped rod drives the cylindrical slider to rotate in the groove. The cylindrical slider drives the straight groove rod to swing back and forth, the straight groove rod drives the storage tank to swing back and forth, and the storage tank drives the blood bag inside to swing back and forth, which can make the blood flow and prevent coagulation.

[0004] However, the aforementioned blood storage device in the hematology department can only store one blood bag at a time, resulting in a relatively low transportation rate.

Detailed Implementation

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Please see Figure 1 and Figure 2 A blood storage device for hematology, which can be used in conjunction with an air cooler that can generate cooling gas, wherein the gas flow circuit of the air cooler is connected to two cooling channels 15 through pipes.

[0021] For buffered collision protection, please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4A protective blood bag storage mechanism 1 is required, which includes a hollow blood bag storage box 11 for storing blood bags, an arc-shaped elastic sheet 18 for elastically supporting the blood bag storage box 11 and buffering the impact force generated by collision, and a sealing cover 14 for sealing the blood bag storage box 11. After opening the sealing cover 14, the blood bag is placed inside the blood bag storage cavity 12, and then the sealing cover 14 is closed. Personnel can then transport the blood bag by holding the carrying rope 17. During transportation, if a collision occurs, the impact will most likely act on the surface of the arc-shaped elastic sheet 18. Due to the elasticity of the arc-shaped elastic sheet 18 itself, the impact intensity can be buffered, thereby reducing the impact on the blood bag.

[0022] For details regarding the specific structure of the protective blood bag storage mechanism 1, please refer to [link / reference needed]. Figure 3 and Figure 4 The system includes a blood bag storage cavity 12 located inside a blood bag storage box 11. The blood bag storage box 11 has a cover mounting port 13 with an open top at the top of the blood bag storage cavity 12. A sealing cover 14 is detachably installed inside the blood bag storage box 11 located inside the cover mounting port 13. The sealing cover 14 has two cooling channels 15 that communicate with the blood bag storage cavity 12. A lifting rope 17 is fixedly installed on the upper surface of the blood bag storage box 11. One three-dimensional surface of the blood bag storage box 11 has a component mounting port 16 that communicates with the external space and the blood bag storage cavity 12. Multiple arc-shaped elastic plates 18 are fixedly installed on the top of the other three three-dimensional surfaces of the blood bag storage box 11. A bottom support block 19 is fixedly installed at the bottom end of each arc-shaped elastic plate 18. The arc-shaped elastic plate 18 has a semi-circular structure, and the bulge of the annular structure is far away from the blood bag storage box 11, thus forming an arc-shaped protection zone.

[0023] To implement anti-clotting measures for blood bags, please refer to [link / reference needed]. Figure 2 , Figure 5 and Figure 6 A rotating driven mechanism 2 is required, which includes a polygonal rotating shell 22 for storing and rotating blood bags, an elastic limiting band 23 for elastically binding the blood bags on the surface of the polygonal rotating shell 22, and a fan blade 29 that rotates and generates gas flow inside the blood bag storage box 11. The blood bags are placed on various planes of the polygonal rotating shell 22 and then fixed with the elastic limiting band 23. When the polygonal rotating shell 22 rotates, the blood inside the blood bags circulates under its own weight. At the same time, the rotation of the first horizontal rotating shaft 28 drives the fan blade 29 to rotate. At this time, a gas circulation phenomenon is formed inside the blood bag storage box 11, thereby lowering the temperature around the blood bags. Under the dual effects of low temperature and movement, anti-coagulation measures are achieved for the blood bags.

A first horizontal shaft 28 capable of rotation is placed at the center of the first hollow shaft 26 and the polygonal cavity 24. The shaft body of the first horizontal shaft 28 located inside the first hollow shaft 26 is mounted inside the first hollow shaft 26 by bearings. A wind turbine blade 29 is fixedly installed on the outside of the shaft body located inside the polygonal cavity 24. The axis of the first horizontal shaft 28 is on the same horizontal line as the axis of the component mounting port 16. When the wind turbine blade 29 rotates, it can cause the gas around it to have a horizontal flow tendency.

[0025] To achieve a coaxial drive effect and thus improve the kinetic energy utilization of the drive motor 38, please refer to [link / reference needed]. Figure 1 , Figure 2 , Figure 7 and Figure 8 A coaxial drive mechanism 3 needs to be installed, which internally includes a first bevel gear 33 located outside the blood bag storage box 11 and capable of driving the first flange 27 to rotate; a second bevel gear 36 located outside the blood bag storage box 11 and capable of driving the first horizontal rotating shaft 28 to rotate; a third bevel gear 37 located outside the blood bag storage box 11 and capable of driving the first bevel gear 33 and the second bevel gear 36 to rotate synchronously and in opposite directions; and a third bevel gear 37 fixedly installed outside the blood bag storage box 11 and capable of driving... The drive motor 38, which drives the third bevel gear 37 to rotate, is started. The rotor drives the third bevel gear 37 to rotate. Due to the meshing of the teeth, the first bevel gear 33 and the second bevel gear 36 will rotate synchronously on the same axis. The rotation of the first bevel gear 33 will drive the first hollow rotating shaft 26 and the polygonal rotating housing 22 to rotate. The rotation of the second bevel gear 36 will drive the first horizontal rotating shaft 28 and the fan blade 29 to rotate, thereby improving the kinetic energy utilization rate of the drive motor 38.

[0026] For details regarding the specific structure of the coaxial drive mechanism 3, please refer to [link / reference]. Figure 7 and Figure 8 The system includes a second hollow shaft 31 installed inside the component mounting port 16 via bearings and a sealing ring. One end of the second hollow shaft 31 is fitted with a second flange 32, which is integrally formed with and fixedly connected to a first flange 27. The other end of the second hollow shaft 31 is fitted with a first bevel gear 33, which is integrally formed with it. A second horizontal shaft 34 is fixedly installed at the center of the second hollow shaft 31 via bearings and a sealing ring. One end of the second horizontal shaft 34, located inside the first hollow shaft 26, is fixedly connected to one end of the first horizontal shaft 28 via a coupling 35. Next, a second bevel gear 36 with an integral structure is provided at the other end of the second horizontal rotating shaft 34. The drive motor 38 is fixedly installed on the outside of the blood bag storage box 11 through the motor fixing base 39. A third bevel gear 37 is fixedly installed at the rotor end of the drive motor 38. The teeth of the third bevel gear 37 mesh with the teeth of the first bevel gear 33 and the teeth of the second bevel gear 36 respectively. The meshing point of the third bevel gear 37 and the first bevel gear 33 is symmetrically arranged with the meshing point of the third bevel gear 37 and the second bevel gear 36.

[0027] In use, connect the gas flow circuit of the air cooler to the two cooling channels 15 through pipes, turn on the air cooler, open the sealing cover 14, and then place the blood bag on each plane of the polygonal rotating housing 22. Then, use the elastic limit strap 23 to fix the blood bag, close the sealing cover 14, start the drive motor 38, and the rotor drives the third bevel gear 37 to rotate. Due to the meshing of the teeth, the first bevel gear 33 and the second bevel gear 36 will rotate coaxially and synchronously. The rotation of the first bevel gear 33 will drive the first hollow rotating shaft 26 and the polygonal rotating housing 22 to rotate, and the rotation of the second bevel gear 36 will drive the first horizontal rotating shaft 28 and the fan blades 29 to rotate. When the angular rotating shell 22 rotates, the blood inside the blood bag circulates under its own weight. At the same time, the rotation of the first horizontal rotating shaft 28 drives the fan blades 29 to rotate. At this time, a gas circulation phenomenon is formed inside the blood bag storage box 11, which lowers the temperature around the blood bag. Under the combined effect of low temperature and movement, anti-coagulation measures are achieved for the blood bag. Personnel can transport the blood bag by holding the carrying rope 17. During transportation, if a collision occurs, the impact will most likely act on the surface of the arc-shaped elastic sheet 18. Due to the elasticity of the arc-shaped elastic sheet 18 itself, the impact intensity can be buffered, thereby reducing the impact on the blood bag.

[0028] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
