[0017] The beneficial effects of the present application are as follows: 1. The present invention discloses a mobile cooling bed comprising a mobile hospital bed, a waterbed, a water tank, and a miniature chiller.

[0021] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.
[0022] like Figures 1 to 5 As shown in the embodiment of the present invention, a mobile cooling bed includes a mobile hospital bed 1; a waterbed 2 is fixedly connected to the top surface of the mobile hospital bed 1; a water trough 3 for the patient to lie supine is opened on the top surface of the waterbed 2; a miniature chiller 4 is fixedly connected to the top surface of the bottom support of the mobile hospital bed 1; the inlet and outlet of the miniature chiller 4 are respectively connected to the two ends of the water trough 3 through pipes. Specifically, the mobile hospital bed 1 has two parallel crossbeams at its bottom; multiple crossbars are evenly fixed between the two crossbeams; rollers are bolted to the bottom of both ends of the two crossbeams; a support plate is bolted to the top of the middle section between the two crossbeams, and a miniature chiller 4 is bolted to the top of the support plate; a pair of uprights are fixed to the top of the crossbeams; a bed board is fixed to the top of the multiple uprights; baffles are fixed to both ends of the bed board, and wrenches are provided on the baffles for easy pushing by medical staff; the waterbed 2 is fixed to the top of the bed board by bolts, and both ends of the waterbed 2 are in contact with the baffles at both ends respectively; The inlet of the miniature chiller 4 is connected to the end of the water tank 3 near the foot of the water bed 2 via a pipe; the outlet of the miniature chiller 4 is connected to the end of the water tank 3 near the head of the water bed 2 via a pipe. The miniature chiller 4 includes components such as a casing, compressor, condenser, evaporator, refrigerant, water pump, and control panel. The water pump pumps warm water from the water tank 3 into the evaporator. In the evaporator, the refrigerant absorbs heat from the water, cooling it to the target temperature. The chilled water is then pumped out and transported through pipes to the water tank 3. The chilled water in the water tank 3 exchanges heat with the patient, absorbing body heat and lowering the patient's core body temperature. Simultaneously, the water temperature rises. Afterward, the heated water flows back into the miniature chiller 4 for further cooling, forming a closed, continuous water circulation cooling loop. Meanwhile, medical personnel can monitor and control the water temperature, flow rate, and patient's body temperature through the control panel on the miniature chiller 4. The top surface of the pallet of the mobile hospital bed 1 is also fixedly equipped with a lithium battery and an inverter; the lithium battery is electrically connected to the inverter, and the inverter is in turn electrically connected to the micro chiller 4; the lithium battery stores electrical energy, and the inverter converts the DC power of the lithium battery into AC power to power the micro chiller 4 for normal operation; thus facilitating short-distance movement without power support, such as in an ambulance to transfer a patient from the place of onset, or in a hospital for short-distance transfers; when in places where power support can be provided, such as in an ambulance or ward, the power supply can be directly connected to the micro chiller 4 or the inverter for power supply. In practical use, select the appropriate power supply method according to the usage scenario; if short-distance transfer is required, add a lithium battery and an inverter. The inverter converts the DC power of the lithium battery into AC power to power the miniature chiller 4 to work normally; if in an ambulance or ward, directly connect the power supply to the miniature chiller 4 or the inverter for power supply. First, pour clean water into the water tank 3 of the waterbed 2. At the same time, start the mini chiller 4. The mini chiller 4 pumps the clean water in the water tank 3 into the mini chiller 4 to cool it down to the target temperature. The low-temperature chilled water is transported to the water tank 3 through the pipeline until the temperature of the clean water in the water tank 3 drops to the required temperature. Next, the patient is placed in the water tank 3 of the waterbed 2. At the same time, the patient's head is elevated to prevent the water from submerging the patient's mouth and nose, causing choking and suffocation. Meanwhile, the mini chiller 4 is continuously turned on to keep the water in the tank 3 at a constant low temperature. The chilled water in the tank 3 exchanges heat with the patient and absorbs body heat, causing the patient's core body temperature to drop. This effectively lowers the patient's core body temperature and maintains it at a low temperature, providing a stable and safe low-temperature environment for the patient's treatment and transfer; thereby greatly improving the effectiveness of patient treatment and reducing patient injury.
[0023] Furthermore, such as Figures 1 to 4 As shown, the water tank 3 is provided with inclined protrusions 5 on both sides of the end near the head of the water bed 2; an inclined slope 6 is provided between the two inclined protrusions 5. Specifically, the inclined boss 5 and the inclined slope 6 are integrally formed with the waterbed 2 through an injection mold; the side of the inclined boss 5 near the middle of the waterbed 2 is an inclined surface, the top surface of the inclined boss 5 coincides with the top surface of the waterbed 2, and the corner of the inclined boss 5 is provided with an arc-shaped chamfer; the curvature of the inclined slope 6 conforms to the curvature of the human head and neck, which can raise the patient's head. When in use, the patient is placed in the water tank 3 of the waterbed 2 with their head facing one end of the inclined slope 6 and resting on the inclined slope 6. At the same time, the patient's shoulders are resting on the inclined surfaces of the inclined protrusions 5 on both sides. The inclined slope 6 elevates the patient's head, thus preventing the water in the water tank 3 from submerging the patient's mouth and nose, causing choking and suffocation. The inclined protrusions 5 block and limit the patient's shoulders and head, thus preventing the patient's head from turning or the patient from turning over, which could cause choking and suffocation.
[0024] Furthermore, such as Figures 1 to 6 As shown, the bottom of the inclined slope 6 near the middle of the waterbed 2 has a slot 7; a diversion spray seat 8 is fixedly connected inside the slot 7; the diversion spray seat 8 near the middle of the waterbed 2 has multiple water outlets connected to it, and the diversion spray seat 8 away from the middle of the waterbed 2 has a water inlet connected to it; a three-way connector 9 is fixedly connected to the inner wall of the end of the waterbed 2 near the inclined slope 6; the water inlet end of the three-way connector 9 is connected to the water outlet end of the micro chiller 4 through a pipe; the two water outlet ends of the three-way connector 9 are connected to the water inlets of the diversion spray seats 8 on both sides through pipes. Specifically, the diversion spray base 8 has a trapezoidal structure; the side of the diversion spray base 8 closest to the inclined slope 6 is an inclined surface, which coincides with the inclined surface of the inclined slope 6; a groove is provided on the side of the diversion spray base 8 closest to the inclined slope 6, and an inner cavity is provided inside the diversion spray base 8; multiple water outlets are fixedly connected to the side of the groove closest to the inner cavity, and the water outlets are connected to the inner cavity; a water inlet is fixedly connected to the side of the diversion spray base 8 away from the inclined slope 6, and the water inlet is connected to the inner cavity. The miniature chiller 4 pumps clean water from the water tank 3 into the miniature chiller 4 to cool it down to the target temperature. The low-temperature chilled water is then transported through a pipe to the tee connector 9, where it is split into two water spray seats 8 on both sides. The water is then sprayed out from the outlet of the water spray seat 8, allowing the chilled water to spray out from the bottom of the inclined slope 6. This avoids obstruction of the chilled water flow by the patient and, at the same time, facilitates the rapid distribution of chilled water into the water tank 3, thereby improving the rapid and stable decrease of the patient's body temperature.
[0025] In some embodiments, such as Figure 1 , Figure 3 and Figure 7 As shown, the top surface of the waterbed 2 is covered with multiple strips 10; a rubber strip 11 is fixed between two adjacent strips 10; Specifically, the length of the strip 10 is greater than the width of the water tank 3, and stepped grooves 12 are provided on both sides of the top surface of the strip 10; the length of the rubber strip 11 is the same as the length of the stepped groove 12, and the thickness of the rubber strip 11 is the same as the thickness of the stepped groove 12; multiple fixing through holes are evenly provided at the overlapping position of the stepped groove 12 and the rubber strip 11, and fixing pins are inserted into the fixing through holes. In use, place one side of the rubber strip 11 into the stepped groove 12 on one side of the strip 10, aligning the fixing through hole on the rubber strip 11 with the fixing through hole in the stepped groove 12. Use fixing pins to pass through the fixing through holes to fix the rubber strip 11 to the strip 10. Alternately fix multiple strips 10 and multiple rubber strips 11 to form an integral cover structure, and the cover structure can cover the area from the tail of the water tank 3 to the inclined boss 5. The cover structure composed of strips 10 and rubber strips 11 covers the top surface of the water tank 3, effectively insulating the inside of the water tank 3, thereby improving the constantness of the water temperature inside the water tank 3, and effectively reducing the overflow of water in the water tank 3 due to shaking. Furthermore, the strips 10 are connected by rubber strips 11, making it easy to fold and store multiple strips 10, thus facilitating storage.
[0026] Furthermore, such as Figures 1 to 7 As shown, magnetic strips 13 are fixed to both sides of the top surface of the waterbed 2; iron blocks 14 are fixed to both ends of the strip 10; the iron blocks 14 can be attracted by the magnetic strips 13. Specifically, long strip grooves are provided on both sides of the top surface of the waterbed 2, i.e., on both sides of the top surface of the water tank 3. The magnetic strip 13 is fixedly installed in the long strip grooves with glue. Square grooves are provided at both ends of the strip 10. The iron block 14 is fixedly installed in the square grooves. By attracting the iron block 14 and the magnetic strip 13, the two ends of the strip 10 are fixed to both sides of the top surface of the waterbed 2, thereby fixing the strip 10 to the top surface of the water tank 3, thus preventing the strip 10 from shifting or falling due to shaking.
[0027] In some embodiments, such as Figures 2 to 8 As shown, water pipes 15 are fixedly connected to the top of both sides of the water tank 3; the water inlet of the water pipe 15 is connected to one of the water outlets of the diversion spray base 8; and multiple atomizing nozzles 16 are connected to the side of the water pipe 15 near the middle of the water tank 3. Specifically, the water pipe 15 is fixedly installed to the top of the side wall of the water tank 3 by a pipe clamp. One end of the water pipe 15 is connected and fixed to one of the outlets of the diversion spray seat 8, and the other end is sealed and blocked by a sealing plug. Multiple water outlets are evenly arranged on the side of the water pipe 15 near the middle of the water tank 3. The water inlet of the atomizing nozzle 16 is connected to the water outlet of the water pipe 15. When the low-temperature cold water is sprayed out from the outlet of the diversion spray seat 8, part of the low-temperature cold water is transported into the water pipe 15 and then atomized and sprayed out by multiple atomizing nozzles 16. At the same time, due to the obstruction of the strip plate 10 and the rubber strip 11, a low-temperature water mist is formed inside the water tank 3. This further ensures the low-temperature environment inside the water tank 3, thereby ensuring that the part of the patient's body surface that is not immersed in the low-temperature cold water can still receive good cooling treatment.
[0028] Furthermore, such as Figures 2 to 8 As shown, a suction cup 17 is provided on the top of the atomizing nozzle 16; the suction cup 17 can be attached to the bottom surface of the strip plate 10. Specifically, the atomizing nozzle 16 has an annular groove around its outer ring; the bottom of the suction cup 17 is a rubber ring; the rubber ring is fitted around the annular groove of the atomizing nozzle 16, and the rubber ring is firmly fixed to the outer ring of the atomizing nozzle 16 by its own elasticity, thereby fixing the suction cup 17 to the atomizing nozzle 16; the suction cup 17 and the bottom surface of the strip plate 10 are attracted by negative pressure, so that the atomizing nozzle 16 is fixed to the bottom of the strip plate 10, thereby restricting the position of the atomizing nozzle 16 and preventing the atomizing nozzle 16 from falling into the low-temperature cold water in the water tank 3, thus ensuring the atomization effect.
[0029] In some embodiments, such as Figure 2 , Figure 3 and Figure 9 As shown, a rubber pad 18 is fixed to the top surface of the inclined slope 6; a plurality of anti-slip protrusions are uniformly fixed to the top surface of the rubber pad 18. Specifically, the bottom surface of the rubber pad is bonded and fixed to the inclined slope 6 with glue; the anti-slip protrusions on the top surface of the rubber pad 18 increase the frictional resistance with the patient's body surface, thereby preventing the patient's head from slipping off the inclined slope 6 and thus improving the patient's safety.
[0030] In some embodiments, such as Figure 2 , Figure 3 and Figure 10 As shown, a back pad 19 is fixedly attached to the bottom surface of the water tank 3 near the inclined slope 6; elastic straps 20 are fixedly attached to both sides of the back pad 19; and a buckle 21 is fixedly attached to the end of the elastic strap 20 away from the back pad 19. Specifically, the back pad 19 has a square rubber pad in the middle, and the square rubber pad is fixed with fixing straps on both sides near the inclined slope 6. The ends of the fixing straps are fixed and locked to the bottom of the water tank 3 by screws. The screws are locked close to the side of the water tank 3 to avoid affecting the patient. When in use, the patient lies supine in the water tank 3 of the waterbed 2. At this time, the back pad 19 is located on the bottom of the patient's back. The elastic straps 20 on both sides are wrapped from under the patient's armpits to the patient's chest, and the buckles 21 on both sides are locked together. The elasticity of the elastic straps 20 and the fixation of the back pad 19 and the water tank 3 are used to fix and restrain the patient. This not only prevents the patient from slipping and drowning, but also prevents the patient from shaking and causing danger during the transfer.
[0031] In some embodiments, such as Figure 2 , Figure 3 , Figure 4 and Figure 11 As shown, a plurality of slots 22 are evenly provided on the bottom surface of the end of the water tank 3 away from the inclined slope 6; a foot plate 23 is inserted into the slot 22; a plurality of support rods 24 are hinged to the side of the foot plate 23 away from the inclined slope 6; the bottom end of the support rod 24 can be inserted into the slot 22. Specifically, multiple water channels are evenly provided on the foot plate 23, and multiple pairs of inserts are bolted to the side of the foot plate 23 away from the inclined slope 6. A hinge rod is rotatably installed between each pair of inserts, and the hinge rod passes through one end of the support rod 24. In use, the patient lies supine in the water tank 3 of the waterbed 2, with their head resting on the inclined slope 6. The footboard 23 is inserted into a slot 22 near the patient's feet, allowing the patient's feet to rest on the footboard 23. At the same time, the support rod 24 is rotated, causing it to insert into another slot 22, providing support for the footboard 23. By providing support for the patient's feet, the risk of slipping and drowning is further prevented, improving the patient's stability. Furthermore, the interaction between the footboard 23 and the slot 22 allows for easy adjustment according to the patient's height, making it suitable for patients of different heights.
[0032] Working principle: Select the appropriate power supply method according to the usage scenario; if short-distance transfer is required, add a lithium battery and an inverter. The inverter converts the DC power of the lithium battery into AC power to power the miniature chiller 4 for normal operation; if in an ambulance or ward, directly connect the power supply to the miniature chiller 4 or the inverter for power supply. First, pour clean water into the water tank 3 of the waterbed 2. At the same time, start the mini chiller 4. The mini chiller 4 pumps the clean water in the water tank 3 into the mini chiller 4 to cool it down to the target temperature. The low-temperature chilled water is transported to the water tank 3 through the pipeline until the temperature of the clean water in the water tank 3 drops to the required temperature. Next, the patient is placed in the water tank 3 of the waterbed 2, with the patient's head facing one end of the inclined slope 6 and resting on the inclined slope 6. At the same time, the patient's shoulders are resting on the inclined surfaces of the inclined protrusions 5 on both sides. At this time, the back pad 19 is located on the bottom of the patient's back. The elastic straps 20 on both sides are wrapped from under the patient's armpits to the patient's chest, and the buckles 21 on both sides are locked together. The elasticity of the elastic straps 20 and the fixation of the back pad 19 and the water tank 3 are used to fix and restrain the patient. Then, the footboard 23 is inserted into a slot 22 near the patient's feet, so that the patient's feet can step on the footboard 23. At the same time, the support rod 24 is rotated so that the support rod 24 is inserted into another slot 22 to support the footboard 23. The cover structure composed of the strip 10 and the rubber strip 11 covers the top surface of the water tank 3. Meanwhile, the miniature chiller 4 is continuously turned on, keeping the water in the water tank 3 at a constant low temperature. The chilled water in the water tank 3 exchanges heat with the patient, absorbing body heat and lowering the patient's core body temperature. At the same time, some of the low-temperature chilled water is transported to the water pipe 15 and then atomized and sprayed out by multiple atomizing nozzles 16. Meanwhile, due to the obstruction of the strip plate 10 and the rubber strip 11, a low-temperature water mist is formed inside the water tank 3. This effectively lowers the patient's core body temperature and maintains it at a low temperature, providing a stable and safe low-temperature environment for the patient's treatment and transfer; thereby greatly improving the effectiveness of patient treatment and reducing patient injury.
