Abstract
Description
Technical Field
[0001] This invention relates to the field of emergency medical equipment technology, and more specifically, to a portable heatstroke emergency medical device for ambulances. Background Technology
[0002] Heatstroke is the most severe form of heat-related emergency, also known as severe heatstroke. It is a serious and fatal illness accompanied by burning skin, altered consciousness (such as delirium, seizures, and coma), and multiple organ dysfunction. It is the most severe type of heatstroke, and once it occurs, the mortality rate is extremely high. The first treatment for patients with heatstroke should be to cool them down rapidly. Cooling methods for heatstroke are generally divided into two categories: external cooling and internal cooling.
[0003] For example, Chinese utility model patent application number 202021971180.5 provides a heatstroke emergency device. This device includes a tank, with a groove on one end of the tank's inner wall for placing the patient's head. A cooling mechanism for cooling the patient's head is located within the groove's side wall. A set of through holes, communicating internally and externally, are respectively opened on the side walls of both ends of the tank, and fans are installed inside each of these through holes. This device can provide comprehensive cooling of the patient's entire body through the fans.
[0004] However, most existing portable cooling devices do not cover the patient's skin surface well, and large cooling devices are difficult to fit into ambulances. This makes it difficult to control the patient's body temperature during the most critical cooling period after the onset of heatstroke, which in turn increases the patient's morbidity and mortality rate and reduces the effectiveness of the devices. Summary of the Invention
[0005] This invention provides a portable heatstroke emergency device for ambulances, which solves the problems of existing portable cooling devices having low coverage of the patient's skin surface and large cooling devices being difficult to fit into ambulances, thus increasing the patient's morbidity and mortality rates and reducing the effectiveness of the device.
[0006] To achieve the above objectives, the present invention provides the following technical solution:
[0007] A portable heatstroke emergency device for ambulances includes a housing and a cooling assembly. One end of the housing is fitted with a neck brace, and the other end with a push rod. The cooling assembly includes an overflow trough connected to the other end of the housing. The lowest point of the overflow trough's connection to the housing is at the same height as the lowest point of the neck brace. A water inlet pipe is connected to the bottom of the overflow trough, and a first water pump is connected to the water inlet pipe. A cooling box is connected to the free end of the water inlet pipe. A placement slot is provided on one side of the cooling box. The cooling box contains a vertically placed partition and a horizontally placed grid. The highest point of the grid is lower than the lowest point of the outlet end of the placement slot. One side of the cooling box is connected to the housing via a return flow assembly.
[0008] Preferably, the top of the cooling box is provided with an air outlet pipe, and the bottom of the placement tank is provided with a rotatably connected isolation block. One end of the isolation block is coaxially provided with a rotating handle, and the outer edge of the isolation block is in contact with the inner wall of the bottom outlet of the placement tank.
[0009] Preferably, the reflux assembly includes a water outlet tank connected to one side of the cooling tank via a pipe. The water outlet tank is located at one end of the tank body. A second water pump is connected to the pipe between the water outlet tank and the cooling tank. Multiple water outlet pipes are provided on the side of the water outlet tank near the tank body. Multiple water inlet holes are opened at one end of the tank body. Each water outlet pipe is fitted into one of the water inlet holes.
[0010] Preferably, guide blocks are provided on the inner sidewalls of both sides of the box body, and a fixing block is provided at the bottom of the guide block. A permeable plate with sliding connection is provided inside the box body. Guide grooves are opened on both sides of the permeable plate, and the guide blocks are locked in the guide grooves. A connecting frame is provided at both ends of the permeable plate, and a connecting seat is provided at both ends of the box body. The connecting frame and the connecting seat are connected by a first hydraulic rod.
[0011] Preferably, a water-repelling assembly is provided on the bottom wall of the box body. The water-repelling assembly includes a waterproof motor provided on the bottom wall of the box body. The output shaft end of the waterproof motor is provided with a lead screw rotatably connected by a coupling. A movable seat is provided on the lead screw. Both ends of the movable seat are provided with through holes. Two guide rods are provided in the box body. The two guide rods are respectively inserted into the two through holes.
[0012] Preferably, two sets of moving components are provided on both sides of the outer wall of the box. The moving components include a pair of first connecting blocks and second connecting blocks on the outer wall of the box. A second hydraulic rod is rotatably connected between the two first connecting blocks. An adjusting seat is rotatably connected to the output rod end of the second hydraulic rod. A universal wheel is rotatably connected to the bottom end of the adjusting seat. The adjusting seat is rotatably locked between the two second connecting blocks.
[0013] Preferably, an arm slot is provided on one side of the box body, and a baffle is provided on one side of the arm slot, with the highest point of the baffle being at the same height as the highest point of the side wall of the box body.
[0014] The principle and beneficial effects of this technical solution:
[0015] (1) The cooling component in this invention can provide large-area coverage cooling for the patient's skin. The patient can lie in the box and pour pre-prepared water into the box so that the patient can be completely immersed in the water for rapid cooling. After the patient's skin comes into contact with the water and exchanges heat, the water temperature will increase, thus increasing the temperature of the cooling water. At this time, the water can be pushed into the overflow tank by the water-pushing component. The water in the box can then enter the cooling box through the water inlet pipe at the bottom of the overflow tank. Filling the placement slot on one side of the cooling box with dry ice or other substances can quickly lower the water temperature in the cooling box. The cooled water will then return to the box through the return component to cool the patient. The cooling component in this device can provide rapid cooling for heatstroke patients in a short period of time, thereby reducing the mortality rate of patients after the onset of heatstroke and improving the effectiveness of the device.
[0016] (2) The water-dispelling component in this invention can dispel the cooling water in the box, so that the water that has undergone long-term heat exchange with the patient's skin can enter the cooling component through the overflow trough set at the rear end of the box for cooling, so as to maintain the cooling effect of the cooling component. When medical staff use the water-dispelling component, they can start the waterproof motor. Since the output shaft of the waterproof motor is equipped with a screw that is rotatably connected by a coupling, and the moving seat for dispelling water is also mounted on the screw, the rotation of the screw will drive the moving seat to move. The moving seat is connected to the guide rod in the box through the through holes at both ends. Therefore, the moving seat can only move along the axis of the screw. Finally, the movement of the moving seat can dispel the water in the box and push the water in the upper layer of the box into the cooling component.
[0017] (3) The movable component set on the outer wall of the box in this invention can help medical staff move the device. Since the device is filled with cooling water and the patient needs to lie on the device, the device will be relatively heavy when carrying the patient. By setting the movable component, it is convenient for medical staff to move the device. When medical staff need to move the device, the adjustment seat needs to be rotated to the horizontal position and the second hydraulic rod is driven to extend. Since the output rod end of the second hydraulic rod is hinged to the adjustment seat and the adjustment seat is rotated and locked between the two second connecting blocks, the extension of the second hydraulic rod will drive the adjustment seat to rotate along the hinge point between it and the second connecting block until the adjustment seat is rotated to the horizontal position. At this time, the push rod set at one end of the box can be used to move the device in conjunction with the universal wheel at the bottom of the adjustment seat. Attached Figure Description

[0024] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments:
[0025] Example:
[0026] like Figures 1 to 5 As shown, the present invention provides a portable heatstroke emergency device for ambulances, including a housing 2 and a cooling component. A neck guard 6 is provided at one end of the housing 2, and a push rod 24 is provided at the other end of the housing 2. The cooling component includes an overflow trough 23 connected to the other end of the housing 2. The lowest point of the overflow trough 23 at the connection with the housing 2 is at the same height as the lowest point of the neck guard 6. A water inlet pipe 26 is connected to the bottom end of the overflow trough 23. A first water pump 27 is connected to the water inlet pipe 26. A cooling box 16 is connected to the free end of the water inlet pipe 26. A placement slot 18 is provided on one side of the cooling box 16. A vertically placed partition 36 and a horizontally placed grid 15 are provided inside the cooling box 16. The highest position of the grid 15 is lower than the lowest position of the outlet end of the placement slot 18. One side of the cooling box 16 is connected to the housing 2 through a return component.
[0027] like Figure 2 and Figure 5As shown, the top of the cooling box 16 is provided with an air outlet pipe 12, and the bottom of the placement tank 18 is provided with a rotatably connected isolation block 13. One end of the isolation block 13 is coaxially provided with a handle 14, and the outer edge of the isolation block 13 is in contact with the inner wall of the bottom outlet of the placement tank 18.
[0028] Since the cooling component in this device needs to be filled with dry ice or other substances in the placement tank 18 for cooling during use, but excessive carbon dioxide can easily lead to low oxygen levels in the ambulance, causing suffocation, the outer edge of the isolation block 13 rotatably connected to the bottom of the placement tank 18 contacts the inner wall of the bottom outlet of the placement tank 18. By rotating the handle 14 at one end of the isolation block 13, the dry ice on the isolation block 13 can be pushed into the cooling box 16. The gas produced after the dry ice sublimates in the cooling box 16 will not be able to enter the placement tank 18 in large quantities due to the isolation of the isolation block 13. The gas will continue to rise and eventually be discharged to the outside of the ambulance through the exhaust pipe 12 connected to the top of the cooling box 16.
[0029] like Figure 1 and Figure 2 As shown, the reflux assembly includes a water outlet tank 7 connected to one side of the cooling tank 16 via a pipe. The water outlet tank 7 is located at one end of the tank body 2. A second water pump 10 is connected to the pipe between the water outlet tank 7 and the cooling tank 16. The second water pump 10 can pump water from the cooling tank 16 into the water outlet tank 7. Multiple water outlet pipes 8 are provided on the side of the water outlet tank 7 near the tank body 2. Multiple water inlets 1 are opened at one end of the tank body 2. Each water outlet pipe 8 is inserted into one water inlet 1. Since high heat can damage the patient's organs, in order to minimize the harm of heatstroke, the water outlet tank 7 is located at the end of the tank body 2 where the neck brace 6 is provided, so that the cool water at a lower temperature can first be applied to the skin of the patient's chest and abdomen to preferentially reduce the internal temperature of the patient's chest and abdominal cavities. At the same time, in order to avoid the large flow of water directly washing the patient's skin and causing the patient to shiver due to the rapid temperature drop, water is discharged from one side of the water outlet tank 7 through multiple water outlet pipes 8 to reduce the direct stimulation of the cooling water on the patient.
[0030] like Figures 1 to 4 As shown, guide blocks 34 are provided on the inner sidewalls of both sides of the box body 2. A fixing block 35 is provided at the bottom of the guide block 34. The fixing block 35 can limit the lowest position of the permeable plate 3 to prevent the permeable plate 3 from obstructing the movement of the moving seat 30. A permeable plate 3 with sliding connection is provided inside the box body 2. Guide grooves 5 are opened on both sides of the permeable plate 3. The guide block 34 is locked in the guide groove 5. The permeable plate 3 is kept horizontal when it is raised by the locking relationship between the guide groove 5 and the guide block 34, so as to prevent the patient from rolling down due to the tilt of the permeable plate 3. A connecting frame 4 is provided at both ends of the permeable plate 3. A connecting seat 22 is provided at both ends of the box body 2. The connecting frame 4 and the connecting seat 22 are connected by a first hydraulic rod 11.
[0031] When a patient needs to be transferred, this device can lift the patient using the permeable plate 3 to help medical staff transfer the patient. This drives the first hydraulic rod 11 to extend. Since the connecting frame 4 on the permeable plate 3 is connected to the connecting seat 22 on the box 2 through the first hydraulic rod 11, the extension of the first hydraulic rod 11 can lift the permeable plate 3 to lift the patient and help medical staff transfer the patient.
[0032] like Figure 1 , Figure 3 and Figure 4 As shown, a water-repelling assembly is provided on the bottom wall of the box 2. The water-repelling assembly includes a waterproof motor 20 installed on the bottom wall of the box 2. The output shaft end of the waterproof motor 20 is provided with a lead screw 29 rotatably connected by a coupling. A movable seat 30 is installed on the lead screw 29. Both ends of the movable seat 30 are provided with through holes 21. Two guide rods 37 are provided inside the box 2. The two guide rods 37 are respectively installed in the two through holes 21.
[0033] The water-dispensing component can dispense the cooling water inside the housing 2, allowing the water that has undergone prolonged heat exchange with the patient's skin to enter the cooling component through the overflow trough 23 at the rear of the housing 2 for further cooling, thus maintaining the cooling effect of the cooling component. When using the water-dispensing component, medical staff can start the waterproof motor 20. Since the output shaft of the waterproof motor 20 is equipped with a lead screw 29 that is rotatably connected via a coupling, and the water-dispensing movable seat 30 is mounted on the lead screw 29, the rotation of the lead screw 29 will drive the movable seat 30 to move. The movable seat 30 is connected to the guide rod inside the housing 2 through the through holes 21 at both ends. Therefore, the movable seat 30 can only move along the axis of the lead screw 29. Finally, by moving the movable seat 30, the water inside the housing 2 can be dispensed, and the water located on the upper layer of the housing 2 can be dispensed into the cooling component.
[0034] like Figure 1 and Figure 3 As shown, two sets of moving components are provided on both sides of the outer wall of the box 2. The moving components include a pair of first connecting blocks 25 and second connecting blocks 28 on the outer wall of the box 2. A second hydraulic rod 19 is rotatably connected between the two first connecting blocks 25. An adjusting seat 31 is rotatably connected to the output rod end of the second hydraulic rod 19. A universal wheel is rotatably connected to the bottom end of the adjusting seat 31. The adjusting seat 31 is rotatably locked between the two second connecting blocks 28.
[0035] The movable component helps medical staff move the device. Because the device is filled with cooling water and the patient needs to lie on top of it, the device is quite heavy when carrying a patient. The movable component makes it easier for medical staff to move the device. When medical staff need to move the device, they need to rotate the adjusting seat 31 to a horizontal position and drive the second hydraulic rod 19 to extend. Since the output rod end of the second hydraulic rod 19 is hinged to the adjusting seat 31, and the adjusting seat 31 is rotated and locked between the two second connecting blocks 28, the extension of the second hydraulic rod 19 will drive the adjusting seat 31 to rotate along its hinge with the second connecting blocks 28 until the adjusting seat 31 is rotated to a horizontal position. At this time, the push rod 24 set at one end of the housing 2 can be used in conjunction with the universal wheels at the bottom of the adjusting seat 31 to push the device to move. After the medical staff pushes the device into the ambulance, in order to prevent the device from shaking excessively in the ambulance, the adjusting seat 31 can be rotated to a vertical position in the same way.
[0036] like Figure 1 and Figure 4 As shown, an arm placement groove 33 is provided on one side of the box 2, and a baffle 32 is provided on one side of the arm placement groove 33. The highest point of the baffle 32 is the same as the highest point of the side wall of the box 2. Some patients may experience chills due to the rapid cooling or minor external injuries due to heatstroke. At this time, medical staff can place the patient's right arm in the arm placement groove 33 to administer intravenous medication.
[0037] The specific usage and function of this embodiment are as follows:
[0038] The cooling component in this device can provide large-area coverage cooling for the patient's skin. The patient lies in the chamber 2, and pre-prepared water is poured into it, allowing the patient to be completely immersed for rapid cooling. Heat exchange occurs between the patient's skin and the water, raising the water temperature and thus the cooling water's temperature. The water is then pushed into the overflow tank 23 by the water-dispensing component. The water in chamber 2 then flows into the cooling chamber 16 through the inlet pipe 26 at the bottom of the overflow tank 23. Dry ice or similar substances are added to the placement slot 18 on one side of the cooling chamber 16 to rapidly lower the water temperature. The cooled water then returns to chamber 2 through the reflux component to further cool the patient. This cooling component provides rapid cooling for heatstroke patients in a short period, thereby reducing the mortality rate after the onset of heatstroke and improving the device's effectiveness.
