[0026] See also Figure 1-8 A double-shoulder vaccination refrigerator, comprising a main bag 101, a cover 102 sewn on one side of the main bag 101, a shoulder strap 103 fixedly connected to the rear side of the main bag 101, and a handle 104 detachably connected to the upper end of the main bag 101, first placement boxes 107 are fixedly connected at positions on both sides of the main bag 101, a refrigeration shell 3 is arranged between the first placement boxes 107 on both sides, a second placement box 108 drawn forward is arranged on the lower side of the refrigeration shell 3, semiconductor refrigeration sheets are arranged on the left and right sides of the refrigeration shell 3, and a clamping component 6 for shock absorbing the vaccine tube is arranged in the first placement box 107.

[0027] Specifically, the main bag 101 and the cover 102 are made of materials with high hardness and light weight. One side of the front end surface of the main bag 101 is sewn and connected to one side of the cover 102 through an extended cloth, and the other sides are sewn with a parent-child zipper for closing, so that the whole can be closed, ensuring the hygiene and temperature inside. In order to enhance the storage of the refrigerator, a groove 105 is set on the inner side of the cover 102, and an elastic interlayer 106 is bonded to the inner surface of the cover 102 to form a placement cavity with the groove 105, which is used to place the protective clothing of medical staff and commonly used medical protective supplies. The front end surface of the main bag 101 is not connected to the groove 105, which ensures the hygiene of the medical supplies in the main bag 101 and the items in the placement cavity, and prevents bacterial infection.

[0028] The main bag 101 is hollow inside, and the main bag 101 is divided into two parts, an upper part and an lower part, by a fixedly connected partition. There are three first placement boxes 107 on each side, and the outer sides of the uppermost and lowermost first placement boxes 107 are rotatably connected with pull rings; openings are provided on both sides of the main bag 101, and the height of the openings is consistent with the sum of the heights of the three first placement boxes 107. The two first placement boxes 107 on the upper side are connected to the main bag 101 through a connecting rod assembly 2, so that the two first placement boxes 107 on the upper end can be folded and unfolded, and the first placement box 107 on the lower side can be drawn and arranged in the main bag 101, and vaccine tubes are placed in the two first placement boxes 107 on the upper end. The first placement box 107 at the bottom is used to place disinfection products; in order to prevent the first placement box 107 from being opened at will, one end of a nylon tape is bonded to the upper and lower ends of the left and right sides of the main bag 101 near the first placement boxes 107 at the top and bottom, and the bonding length is half of the total length. The length of the nylon tape exceeds the length of the pull ring near the end, and the outer surface of the nylon tape is sewn with mutually matching Velcro. When the first placement box 107 needs to be fixed, the non-fixed end of the nylon tape passes around the pull ring, and the two sections of Velcro cooperate with each other. By cooperating with the pull ring and the nylon tape, the first placement box 107 is prevented from being opened when the refrigerator is carried, and the first placement box 107 is temporarily fixed by limiting the position;

[0029] The opposite surfaces of the first placement boxes 107 on both sides are in contact with the refrigeration shell 3, and a plurality of air holes are provided on a side surface of the first placement box 107 corresponding to the refrigeration shell 3. The refrigeration shell 3 is a cylindrical structure with a square outside and a round inside, that is, a garbage cavity 301 formed by a cylindrical hole is provided in the refrigeration shell 3, and air holes 302 communicating with the garbage cavity 301 are provided on the left and right side walls and the bottom end of the refrigeration shell 3 corresponding to the first placement box 107, and the air holes are connected to the air holes 302; the front and rear sides of the refrigeration shell 3 are fixed on the inner wall of the main bag 101, and the bottom end of the refrigeration shell 3 is fixed on the upper surface of the partition, and the refrigeration shell 3 and the main bag 101 form an integrated structure, and the refrigeration shell Semiconductor refrigeration sheets are bonded to the left and right sides of 3. By setting the semiconductor refrigeration sheets, the main bag 101 can meet the refrigeration conditions required for vaccines. In order to prevent cold air from escaping from the upper end of the refrigeration shell 3, a sealing cover 109 is set at the upper end of the refrigeration shell 3. The external thread 1015 set on the outer surface of the sealing cover 109 cooperates with the internal thread set at the upper end of the refrigeration shell 3. The sealing cover 109 is flush with the upper surface of the main bag 101. The bottom end of the handle 104 is fixedly connected to the sealing cover 109. When medical waste needs to be placed, the handle 104 can be rotated. When the refrigerator needs to be lifted and the internal temperature is guaranteed, the handle 104 can be rotated and installed.

[0030] The lower end of the front side of the main bag 101 is provided with an opening, the size of the opening is consistent with the size of the second placement box 108, the second placement box 108 at the lower part is used to place the vaccine bottle containing powdered medicine, the partition is provided with a clamping hole at a position corresponding to the bottom end of the refrigeration shell 3, the refrigeration shell 3 is fixed in the clamping hole, and its bottom end is against the top of the second placement box 108, and the bottom end of the refrigeration shell 3 is provided with an air hole 302, which is connected to the second placement box 108, so as to further ensure the temperature environment of the second placement box 108;

[0031] A power module and a control module are arranged in the space on the upper side of the first placement box 107 at the top. The power module is a built-in rechargeable battery, which adopts a low-power lithium-ion rechargeable battery. A charging port is arranged at the top of the main bag 101 corresponding to the rechargeable battery, and a sealing gasket is arranged at the position of the charging port; the control module includes a main control chip, a touch screen and a temperature sensor. The touch screen and the temperature sensor are connected to the main control chip for communication. The temperature sensor is installed on the bottom wall of the refrigeration shell 3, and the temperature sensor is used to measure the temperature of the inner center of the refrigeration shell 3;

[0032] In order to prevent the vibration generated by medical staff when placing the refrigerator from causing damage to the medical supplies in the first placement box 107 and the second placement box 108, a buffer device is arranged at the bottom end of the main bag 101, and the buffer device includes a buffer block 1011, a mounting plate 1012 and a first spring 1013. The buffer block 1011 is installed at the bottom end of the mounting plate 1012, and the bottom end of the mounting plate 1012 is connected to the bottom end of the main bag 101 through the first spring 1013. The bottom end of the buffer block 1011 is fixedly connected to a rubber pad 1010, and the bottom end of the main bag 101 is connected to the mounting plate 1012 through an elastic connecting cloth 1014. The interior of the buffer block is hollow and arranged with an airbag bag, and the buffer block is made of rubber material.

[0033] like Figure 4 As shown, a placement plate 4 is provided at the upper part of the first placement box 107 , a plurality of placement spaces 402 are opened on the placement plate 4 , and a clamping assembly 6 for fixing the vaccine tube is provided in the placement space 402 .

[0034] Specifically, the height of the first placement box 107 is greater than the height of the vaccine tube and the up and down movement trajectory. The placement space 402 is a plurality of strip holes arranged at equal intervals along the horizontal direction of the placement plate 4. The width of the placement space 402 can adapt to the vaccine tube with the largest diameter. The opposite surface of the placement space 402 is provided with a plurality of groups of corresponding countersunk holes 401. The corresponding countersunk holes 401 are provided with clamping assemblies 6 for fixing the vaccine tube. The longitudinal cross-section of the countersunk holes 401 is circular. The length of the countersunk holes 401 is required to ensure that the mutually cooperating clamping assemblies 6 on both sides can move to the maximum extent. By setting the clamping assemblies 6, not only can vaccine tubes of different diameters be clamped, but also the vibration generated when the refrigerator is moved can be reduced.

[0035] like Figure 5 and Figure 6 As shown, the clamping assembly 6 is an elastic member, and the clamping assembly 6 can move within the side wall of the placement space 402 and always partially cover the vaccine tube circumferentially.

[0036] Specifically, the clamping assembly 6 includes a slider 601, a connecting block 602, an insert ring 603, a snap ring 604 and an elastic spring 605. The slider 601 is slidably connected in the counterbore 401. The bottom wall of the counterbore 401 and the slider 601 are connected by an elastic spring 605. The outer end surface of the slider 601 is fixedly connected to the connecting block 602. The connecting blocks 602 on both sides are fixedly connected to the insert ring 603 and the snap ring 604 respectively. The insert ring 603 can be plugged into the snap ring 604. The insert ring 603 and the snap ring 604 in the plugged state are located in the placement space 402.

[0037] The end of the counterbore 401 is fixedly connected with a ring-shaped stopper (for example, a ring is fixed at the end of the counterbore 401 by screws as a stopper), and the slider 601 is an oblate structure. The diameter of the slider 601 is consistent with the diameter of the counterbore 401, and the slider 601 is always located in the space between the stopper and the side wall of the counterbore 401. The inner diameter of the stopper is smaller than the outer diameter of the slider 601 (that is, the inner diameter of the stopper is smaller than the diameter of the counterbore 401), thereby preventing the slider 601 from falling out of the counterbore 401 when moving left and right. The connecting block 602 is cylindrical as a whole, and the end of the connecting block 602 away from the slider 601 is an arc-shaped structure, which can fit with the wall of the vaccine tube for easier clamping. The end face of the connecting block 602 is bonded with a silicone sheet, so that the refrigerator can be The vaccine tube is made more stable; the insert ring 603 is a superior arc structure, and the clamp ring 604 is a semi-arc structure. After the insert ring 603 and the clamp ring 604 are assembled, an annular structure is formed that can surround and cover the vaccine tube. A plug hole is provided inside the clamp ring 604, and the shape and size of the plug hole are consistent with the insert ring 603. When the top of the insert ring 603 is against the bottom wall of the plug hole, the circular hole formed by the insert ring 603 inserted in the clamp ring 604 is smaller than the diameter of the smallest vaccine tube on the market; in order to make the insert ring 603 and the clamp ring 604 better cooperate, the insert ring 603 and the clamp ring 604 are made of highly elastic non-slip rubber material, and by setting an elastic spring, it is more convenient to clamp and fix the vaccine tube, and when the medical staff carries the refrigerator on their backs or lifts the refrigerator to run or walk, the vibration of the refrigerator to the vaccine tube is reduced;

[0038] When the ends of the vaccine tubes are fixed, the refrigerator shakes. In order to prevent the tails of the vaccine tubes from colliding and breaking each other, a buffer pad 8 for clamping the bottom ends of the vaccine tubes is provided on the lower side of the placement plate 4. The buffer pad 8 is provided with a number of semi-elliptical grooves for plugging in the tails of the vaccine tubes. The diameter of the grooves is smaller than the diameter of the tails of the vaccine tubes, so that the buffer pad 8 can better wrap the tails of the vaccine tubes. The buffer pad 8 is made of sponge and other materials. The bottom end of the buffer pad 8 is fixedly connected to the bottom plate 7. The bottom end of the bottom plate 7 and the bottom wall of the first placement box 107 are connected by a second spring 9. By arranging the clamping assembly 6 and the buffer pad 8 to cooperate with each other, the damage to the vaccine tubes during transportation and impact can be reduced.

[0039] like Figure 7 and Figure 8As shown, two layers are arranged in the second placing box 108, and the layers are made of pearl cotton material with good resilience and buffering performance, which can better protect the vaccine bottle. The upper and lower layers are stacked together, and the upper and lower layers in the layer plate are fixedly connected with a pull rope 13, the left and right ends of the lower layer plate are fixedly connected to the pull rope 13, and the front and back ends of the upper layer plate are fixedly connected to the pull rope 13, one end of the pull rope 13 is bonded to the bottom end of the layer plate, and the other end extends out of the upper layer plate, the layer plates include a lower layer plate 10 and an upper layer plate 11, and the upper layer plate 11 is bonded to the lower layer plate 10, and the lower layer plate 10 and the upper layer plate 11 are both provided with a number of corresponding card holes 12, the card holes on the lower side are larger than the card holes on the upper side, and the card holes on the upper side are larger than the volume of the vaccine bottle, the vaccine bottle will not fall out of the card holes on the upper side, and will not be broken due to bumps during transportation.

[0040] The working process of the double-backpack vaccination refrigerator provided by the present invention is as follows:

[0041] Before use, start the power supply, set the required temperature on the touch screen, and when the main bag 101 reaches the set temperature, place medical supplies in the first placement box 107 and the second placement box 108, put a garbage bag in the refrigeration shell 3 and screw on the sealing cover 109, and place the protective equipment of medical staff in the groove 105 of the cover surface 102; when using, just pull open the placement box for the required medical supplies, open the sealing cover 109 and place the medical garbage.
