[0076] See also Figures 1 to 9The present embodiment provides an electrically heated blood rewarming chamber set, comprising a rewarming chamber 10 and a heat preservation bag.

[0077] The rewarming box 10 can be electrically heated. A plurality of heat preservation bags are provided, and the heat preservation bags can be placed in the rewarming box 10. The heat preservation bags can be used to load blood storage bags. The combination of the rewarming box 10 and the heat preservation bag is a rewarming box set 10. During operation, the blood storage bag is placed in the heat preservation bag and then placed in the rewarming box 10 for rewarming.

[0078] The rewarming box 10 includes a bottom plate 20 , a rectangular plate frame 21 , a side movable plate 22 , a front movable plate 23 , a rear movable plate 24 , a top plate 25 and a locking device 30 .

[0079] The lower end of the rectangular plate frame 21 is connected to the upper end surface of the bottom plate 20, and the rectangular plate frame 21 and the bottom plate 20 enclose a storage chamber. The storage chamber can be used to accommodate a heat preservation bag. Two side movable plates 22 are provided, and the two side movable plates 22 are parallel to each other and the lower ends are both rotatably connected to the rectangular plate frame 21, and the end of the side movable plate 22 away from the rectangular plate frame 21 can be rotated into the storage chamber. The lower end of the front movable plate 23 is rotatably connected to the rectangular plate frame 21, and the end of the front movable plate 23 away from the rectangular plate frame 21 can be rotated into the storage chamber. The rear movable plate 24 is parallel to the front movable plate 23, and the lower end of the rear movable plate 24 is rotatably connected to the rectangular plate frame 21, and the end away from the rectangular plate frame 21 can be rotated into the storage chamber. The rotational connection of the front movable plate 23, the side movable plate 22 and the rear movable plate 24 with the rectangular plate frame 21 can be connected by a flexible material.

[0080] One end of the top plate 25 is rotatably connected to one end of the rear moving plate 24 away from the rectangular plate frame 21. The locking device 30 is used to lock the front moving plate 23, the side moving plate 22 and the rear moving plate 24. Specifically, when the front moving plate 23, the side moving plate 22 and the rear moving plate 24 are erected, they are locked by the locking device 30, thereby presenting a complete body of the rewarming box 10. The front moving plate 23, the side moving plate 22 and the rear moving plate 24 can be combined to form a rectangular frame. The top plate 25 can be covered on the rectangular frame. The top plate 25 can be connected to the side moving plate 22 or the front moving plate 23 by Velcro or other means, and the top plate 25 is only slightly larger than the rear moving plate 24.

[0081] In addition, the outer layer material of the front moving plate 23, the side moving plate 22 and the rear moving plate 24 can adopt a composite structure of PE and EPS foam to achieve heat preservation, light weight and pressure resistance. The inner layer of the front moving plate 23, the side moving plate 22 and the rear moving plate 24 can be provided with a graphene heating layer. The graphene heating layer is powered by an external power supply to heat up the temperature in the reheating box 10.

[0082] In this embodiment, a plurality of heat preservation bags can be stored in a storage cavity formed between the rectangular plate frame 21 and the bottom plate 20, and the side moving plate 22, the front moving plate 23 and the rear moving plate 24 are rotated in sequence and stored in the storage cavity, so that the rewarming box 10 can be folded, thereby reducing the volume and being easy to carry. In addition, the rewarming box 10 is heated by electric heating to achieve blood rewarming, which is lighter than the traditional water bath rewarming box 10, further improving its portability.

[0083] In one embodiment, the rectangular plate frame 21 includes a front substrate 211 , a rear substrate 212 and a side substrate 213 .

[0084] The lower end of the front substrate 211 is connected to the upper end surface of the bottom plate 20, and the upper end of the front substrate 211 is rotatably connected to the lower end of the front moving plate 23. The rear substrate 212 is parallel to the front substrate 211, and the lower end of the rear substrate 212 is connected to the upper end surface of the bottom plate 20, and the upper end of the rear substrate 212 is rotatably connected to the lower end of the rear moving plate 24. Two side substrates 213 are provided, and the two side substrates 213 are parallel to each other and connected to the upper end surface of the bottom plate 20, and the upper ends of the side substrates 213 are rotatably connected to the lower ends of the corresponding side moving plates 22. The front substrate 211, the rear substrate 212 and the two side substrates 213 together form a rectangular plate frame 21.

[0085] The locking device 30 includes two locking components 31 , and each locking component 31 corresponds to each side base plate 213 .

[0086] The locking assembly 31 includes a first limiting cylinder 311 , a first matching cylinder 312 , a first locking rod 313 and a connecting plate 314 .

[0087] There are more than one first limiting cylinder 311, which are connected to the inner wall of the corresponding side base plate 213. There are more than one first matching cylinder 312, which are connected to the inner wall of the corresponding side movable plate 22, and the first matching cylinder 312 corresponds to the first limiting cylinder 311. There are more than one first locking rod 313, and the lower end of the first locking rod 313 can pass through the first matching cylinder 312 and then be inserted into the first limiting cylinder 311. The connecting plate 314 is connected to all the first locking rods 313 on the same side, and the connecting plate 314 is located between the first matching cylinder 312 and the first limiting cylinder 311.

[0088] In this embodiment, when the side movable plate 22 is rotated out of the accommodating cavity to form the box body, when the side movable plate 22 and the side base plate 213 are both maintained in a vertical state, the lower end of the first locking rod 313 is inserted into the first limiting cylinder 311 below, so that the side movable plate 22 and the side base plate 213 maintain a vertical state. Since multiple first locking rods 313 are connected together by a connecting plate 314, one first locking rod 313 or the connecting plate 314 can be pressed to drive all the first locking rods 313 to move.

[0089] In one embodiment, the two first matching cylinders 312 in the same locking assembly 31 are outer-mounted with a limiting block 315. A limiting groove 316 extending downward is formed between the two limiting blocks 315.

[0090] The locking device 30 further includes a main partition 32 and two locking mechanisms 33 .

[0091] The end of the main partition 32 is inserted into the corresponding limiting groove 316 along the vertical direction, and the end of the main partition 32 is slidably matched with the limiting groove 316 along the vertical direction, and the lower end of the main partition 32 can be against the upper end of the connecting plate 314. Specifically, the limiting groove 316 extends vertically, and the upper and lower ends of the limiting groove 316 are open. The size of the end of the limiting groove 316 close to the side moving plate 22 is larger than the end away from the side moving plate 22. The end of the main partition 32 is similar, that is, the width of the end of the main partition 32 is larger than the width of the middle part, so that when the end of the main partition 32 is inserted into the limiting groove 316 from the top of the limiting groove 316, the main partition 32 locks the two side moving plates 22 through the limiting groove 316. Two locking mechanisms 33 are located on both sides of the main partition 32, and the space on both sides of the main partition 32 can be divided into multiple compartments. The locking mechanism 33 can lock the main partition 32 on the bottom plate 20.

[0092] In this embodiment, the main partition 32 is locked on the bottom plate 20. On the one hand, the two ends of the main partition 32 can lock the two side movable plates 22 to increase the stability of the overall structure; on the other hand, the main partition 32 is abutted against the connecting plate 314, which can keep the first locking rod 313 inserted into the first limiting cylinder 311, and keep the connection between the first matching cylinder 312 and the first limiting cylinder 311, so that the side movable plate 22 and the side base plate 213 maintain a stable vertical state, and the box body will not be deformed due to the flipping of the box body.

[0093] In one embodiment, racks 321 are respectively provided on both sides of the main partition plate 32 , and two ends of the racks 321 point to the two side movable plates 22 .

[0094] The locking mechanism 33 includes a driving plate 331 , a driving rod 333 , a driving gear 334 , and a sub-partition plate 335 .

[0095] The driving plate 331 is located on the main partition plate 32 and is slidably arranged on the side of the main partition plate 32. The driving plate 331 is provided with more than one clearance opening 332, and the clearance opening 332 corresponds to the rack 321 on the same side. The driving rods 333 correspond to the number of the clearance openings 332, are vertically arranged on the driving plate 331, and the driving rods 333 are rotatably connected to the driving plate 331. The driving gears 334 correspond to the number of the driving rods 333, are sleeved on the driving rods 333, and are located in the clearance opening 332. The driving gears 334 are meshed with the rack 321 on the same side. The auxiliary partition plates 335 correspond to the number of the driving rods 333, and the auxiliary partition plates 335 are connected to the driving rods 333. After the end of the auxiliary partition plates 335 away from the driving rods 333 rotates, it can approach the front moving plate 23 and the rear moving plate 24.

[0096] In this embodiment, when the driving plate 331 slides on the side of the main partition 32, the driving rod 333 on the driving plate 331 is meshed with the rack 321 on the main partition 32 due to the driving gear 334, thereby driving the driving rod 333 to rotate, and then driving the auxiliary partition 335 to rotate, so that the auxiliary partition 335 can separate the space on the side of the main partition 32 into multiple compartments after the rotation, and the insulation bag can be fixed in each compartment, so that the blood storage bags in the insulation bag are prevented from being stacked and can be heated evenly. A protective layer with a certain elasticity can be set on the inner wall of the auxiliary partition 335, the driving plate 331, the main partition 32, the front moving plate 23, the rear moving plate 24 and the side moving plate 22, and the insulation bag is limited to prevent the insulation bag from shaking too much during movement. The insulation bag can be installed in the compartment by Velcro.

[0097] When storing, the driving plate 331 slides and the auxiliary partition 335 can be retracted to the side of the driving plate 331, so that the auxiliary partition 335, the driving plate 331 and the main partition 32 form a rectangular parallelepiped, which can be conveniently placed in the storage cavity for easy carrying.

[0098] In one embodiment, two strip-shaped installation openings 322 are further provided on the main partition plate 32 , and the length direction of the strip-shaped installation openings 322 is parallel to the length direction of the rack 321 .

[0099] The locking mechanism 33 further includes a sliding rod 336 , a sliding block 337 , a spring 338 and a stopper 339 .

[0100] The two ends of the slide bar 336 are respectively connected to the inner walls of the two ends of the strip-shaped installation opening 322. The slider 337 is slidably mounted on the connecting rod through the opening, and the slider 337 is connected to the driving plate 331. The spring 338 is mounted on the slide bar 336, and the two ends of the spring 338 are respectively against the slider 337 and the inner wall of the end of the strip-shaped installation opening 322. There are more than one stopper 339, which is connected to the front substrate 211 or the rear substrate 212, and is used to block the end of the auxiliary partition 335 away from the driving rod 333.

[0101] In this embodiment, the driving plate 331 is connected to the slider 337. Under the action of the spring 338, the driving plate 331 has a tendency to slide on the main partition 32. Under the action of the spring 338, when the driving plate 331 is initially moved, the auxiliary partition 335 is in a storage state. When it is necessary to form multiple compartments in the box body of the rewarming box 10, after the driving plate 331 moves, the spring 338 is compressed. At this time, the auxiliary partition 335 rotates more than 90 degrees, and then the two ends of the main partition 32 are placed in the corresponding limit grooves 316, and then the driving plate 331 is released. Under the action of the spring 338, the end of the auxiliary partition 335 is blocked by the corresponding stopper 339. At this time, the auxiliary partition 335 and the driving plate 331 are 90 degrees, thereby realizing the formation of multiple compartments. In the above process, it is only necessary to operate the driving plate 331 to move and place the main partition 32 into the box body of the rewarming box 10, so that multiple compartments can be formed in the box body, which is more convenient and efficient.

[0102] In one embodiment, the locking mechanism 33 includes more than one set of connecting components 34; each set of connecting components 34 corresponds to the secondary partition 335;

[0103] The connecting assembly 34 includes a second matching cylinder 341 , a second limiting cylinder 342 and a second locking rod 343 .

[0104] The second matching cylinder 341 is connected to the front moving plate 23 or the rear moving plate 24. The second limiting cylinder 342 is connected to one end of the auxiliary partition plate 335 away from the driving rod 333. The second locking rod 343 can be inserted into the second limiting cylinder 342 through the second matching cylinder 341. The second connecting rod on the same side can be connected together by a connecting piece. The lower ends of the first locking rod 313 and the second locking rod 343 can be ball heads, which are convenient for inserting them downward into the first limiting cylinder 311 or the second limiting cylinder 342. In addition, when the two upper side moving plates 22 rotate into the accommodating chamber, their ends are just located next to the limiting blocks 315 and will not contact the limiting blocks 315, which makes it possible for the second matching cylinder 341 to not contact and interfere with the side moving plates 22 when the front moving plate 23 and the rear moving plate 24 are subsequently flipped into the accommodating chamber.

[0105] In this embodiment, when the main partition 32 and the auxiliary partition 335 are installed in the box body of the rewarming box 10, after the auxiliary partition 335 rotates, the second limiting cylinder 342 abuts against the stopper 339, and at this time, the second limiting cylinder 342 is located below the second matching cylinder 341. The second locking rod 343 is inserted into the second limiting cylinder 342 from above. On the one hand, the cooperation between the second matching cylinder 341, the second locking rod 343 and the second limiting cylinder 342 enables the second matching cylinder 341 and the front moving plate 23 or the rear moving plate 24 to maintain a vertical state, that is, to form a box body; on the other hand, the second matching cylinder 341 limits the second limiting cylinder 342, so that the auxiliary partition 335 cannot be lifted in the vertical direction, so that the main partition 32 is fixed on the bottom plate 20, so that the entire structure is locked.

[0106] In one embodiment, when the blocks 339 in the two locking mechanisms 33 are subjected to the elastic forces of the corresponding springs 338, the directions of the elastic forces are opposite. Specifically, the movement of the drive plate 331 compresses the spring 338, resulting in the generation of the elastic force of the spring 338. Therefore, when the two drive plates 331 compress the spring 338, the movement directions of the drive plates 331 are opposite. Figure 2 When the main partition 32 is installed in the rewarming box 10, the driving plate 331 close to the rear moving plate 24 moves to the right, driving the second limiting cylinder 342 on the auxiliary partition 335 to approach the corresponding block 339 from the left, and the driving plate 331 close to the front moving plate 23 moves to the left, which will drive the auxiliary partition 335 and the second limiting cylinder 342 on it to approach the corresponding block 339 from the right, and then lock it. Therefore, the subsequent unlocking also requires the two driving plates 331 to slide in different directions to achieve unlocking, so as to avoid the whole rewarming box 10 structure falling apart after unlocking due to misoperation. When storing, the spring 338 can drive the auxiliary partition 335 to form a rectangular parallelepiped with the driving plate 331 and the main partition 32; when the internal space of the rewarming box 10 is separated, the spring 338 drives the auxiliary partition 335 and the second limiting cylinder 342 to move and cooperate to form a compartment. In addition, when the compartments are formed, one of the compartments can be used to place a mobile power source for power supply, and the power source is electrically connected to each graphene heating layer through a wiring harness.

[0107] In one embodiment, two sliding holes 335 a are formed on one end of the auxiliary partition 335 away from the driving rod 333 , a clearance hole is formed on one end of the second limiting cylinder 342 facing the auxiliary partition 335 , and a locking hole 343 a is formed on the second locking rod 343 .

[0108] The connecting assembly 34 further includes a support rod 344 and a locking pin 345 .

[0109] Two support rods 344 are provided, one end of the support rod 344 is connected to the outer wall of the second limiting cylinder 342, and the other end of the support rod 344 passes through the corresponding sliding hole 335a and is connected to an anti-dropping block, which can abut against the auxiliary partition 335. One end of the locking pin 345 is connected to the auxiliary partition 335, and the other end of the locking pin 345 passes through the clearance hole and can be inserted into the locking hole 343a.

[0110] In this embodiment, when the second limiting cylinder 342 abuts against the corresponding stop block 339, the second locking rod 343 is inserted downward into the second limiting cylinder 342. The lower end of the second locking rod 343 is a ball head end. After passing through the locking pin 345, the locking pin 345 is temporarily withdrawn and then inserted into the locking hole 343a of the second locking rod 343, thereby locking the second locking rod 343. Even if the entire rewarming box 10 is flipped over, the second locking rod 343 can be stably maintained in the second limiting cylinder 342, and the entire rewarming box 10 will not fall apart.

[0111] In one embodiment, the heat preservation bag is formed by bending and folding a long strip of heat preservation belt 40; when the heat preservation belt 40 is bent and folded, its inner wall can be butted to form a loading cavity with an opening upward; the loading cavity is used to place the blood storage bag; the heat preservation belt 40 contains a graphene heating layer. Specifically, one side of the heat preservation belt 40 has two U-shaped mother-child sides, and when the side is bent and butted (two U-shaped butts), a loading cavity can be formed. The heat preservation belt 40 can also be disassembled into the size of a towel, which can be used as a heating cuff for infusion and blood transfusion. In addition, the heat preservation belt 40 can also be directly wrapped around the outside of the blood storage bag to rewarm it. The heat preservation bag includes from the inside to the outside: a fiber layer, a graphene heating layer, a polyurethane foam insulation layer and a polypropylene outer layer. The graphene heating layers of the 10 groups of the present rewarming box are all externally wired and can be connected to an external mobile power supply. Specifically, the heat preservation bag can realize the rewarming of a single blood storage bag through an external power supply. The heat preservation bag is bonded to the compartment formed by the secondary partition 335 and the main partition 32 by Velcro.

[0112] In summary, the locking device 30 not only locks the front moving plate 23, the rear moving plate 24 and the side moving plate 22 of the rewarming box 10 in an upright state to realize the molding of the rewarming box 10, but also divides the space inside the rewarming box 10 to form multiple compartments.

However, it is understood that embodiments of the present invention can be practiced without these specific details.
