Technical Field

[0001] The invention relates to the technical field of outdoor first aid equipment, in particular to a portable cooling stretcher. Background Art

[0002] In recent years, with the increase in temperature and the frequent occurrence of high temperature weather, the incidence of heat stroke has gradually increased. Heat stroke is a serious health problem caused by high body temperature, especially during sports, outdoor activities or high temperature environments. When first aid personnel provide first aid to people with heat stroke outdoors, they will use portable cooling equipment to cool the body, such as cooling vests, ice bags, etc.

[0003] However, the above existing cooling methods usually rely on physical cooling principles, such as water evaporation or ice cooling. The cooling effects of these devices are often not ideal, and ice or water need to be frequently replaced during use, which increases the complexity of use. In addition, although existing body temperature sensing devices can monitor body temperature in real time, they are rarely used in combination with cooling devices, resulting in a lack of effective temperature control methods during the treatment of heat stroke.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a portable cooling stretcher is proposed. Summary of the invention

[0005] In view of the deficiencies in the prior art, the present invention provides a portable cooling stretcher, which solves the problems raised in the above background technology.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solutions: a portable cooling stretcher, including a stretcher assembly and a semiconductor refrigeration sheet, the stretcher assembly including a hollow rod, a load-bearing cloth, an aluminum film, a scissor-type telescopic frame and a cooling blanket, the interior of the hollow rod is integrated with a battery and a control chip, and the outer wall of the hollow rod is fixedly sleeved with a load-bearing cloth, the surface of the load-bearing cloth is provided with an aluminum film, and scissor-type telescopic frames are provided at both ends of the bottom of the load-bearing cloth, the side of the aluminum film surface close to the hollow rod is connected to the cooling blanket, and the interior of the cooling blanket and between the aluminum film and the load-bearing cloth are provided with semiconductor refrigeration sheets.

[0007] Furthermore, the cold surface of the semiconductor refrigeration sheet is in contact with the aluminum film, and the cold surface of another semiconductor refrigeration sheet is close to the inner side of the cooling quilt.

[0011] Furthermore, the thermometer body is connected to the control chip through a thermometer wire, and the thermometer body is inserted into the thermometer sleeve.

[0012] Furthermore, the stretcher assembly also includes ventilation holes, and ventilation holes are provided on the side of the load-bearing cloth and the aluminum film surface away from the semiconductor refrigeration plate.

[0013] Furthermore, the stretcher assembly also includes a ventilation and cooling fan, and a ventilation and cooling fan is arranged at the bottom of the load-bearing cloth just below the ventilation hole.

[0014] Furthermore, an elastic belt buckle is fixed on the surface of the hollow rod on one side of the cooling quilt, and a female buckle is fixed on the surface of the aluminum film on the other side of the cooling quilt.

[0015] Furthermore, the end of the elastic belt buckle is snap-connected with the end of the female buckle, and two of the elastic belt buckle and the female buckle are provided respectively.

[0016] The present invention provides a portable cooling stretcher, which has the following beneficial effects: 1.

DETAILED DESCRIPTION

[0021] The following embodiments of the present invention are described in further detail in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0022] like Figure 1-Figure 5As shown, the present invention provides a technical solution: a portable cooling stretcher, including a stretcher assembly 1 and a semiconductor refrigeration sheet 2, the stretcher assembly 1 includes a hollow rod 101, a load-bearing cloth 102, an aluminum film 103, a scissor-type telescopic frame 104 and a cooling blanket 105, the hollow rod 101 is internally integrated with a battery and a control chip, and the outer wall of the hollow rod 101 is sleeved and fixed with the load-bearing cloth 102, the surface of the load-bearing cloth 102 is provided with an aluminum film 103, and the bottom ends of the load-bearing cloth 102 are A scissor-type telescopic frame 104 is provided, a cooling blanket 105 is connected to the side of the surface of the aluminum film 103 close to the hollow rod 101, and semiconductor cooling sheets 2 are provided inside the cooling blanket 105 and between the aluminum film 103 and the load-bearing cloth 102, the cold surface of the semiconductor cooling sheet 2 is in contact with the aluminum film 103, and the cold surface of another semiconductor cooling sheet 2 is close to the inner side of the cooling blanket 105, the semiconductor cooling sheet 2 is connected to the battery through a wire, and the battery is connected to the control chip; The specific operation is as follows: the hollow rods 101 are manually separated from each other so that the load-bearing cloth 102 and the aluminum film 103 are unfolded, and the scissor-type telescopic frame 104 is extended accordingly. When the heat stroke patient lies on the aluminum film 103, the scissor-type telescopic frame 104 is unfolded to support the patient from the bottom of the load-bearing cloth 102 to prevent the load-bearing cloth 102 from excessively sinking due to the patient's gravity. After the patient lies down, the cooling blanket 105 is manually covered on the patient's surface. At this time, the semiconductor refrigeration sheet 2 is respectively located on the front chest and back of the human body, and the emergency personnel insert the thermometer body 4 into the patient's armpit or neck. According to the patient's body temperature detected by the thermometer body 4, the battery supplies power to the semiconductor refrigeration sheet 2 to make its cold surface cool to cool the patient's body temperature. The battery adopts a rechargeable battery, and its charging interface is arranged on the outer wall of the hollow rod 101. The control chip controls the cooling effect of the semiconductor refrigeration sheet 2 based on the patient's body temperature to provide the most suitable cooling effect for the patient's body temperature at different stages. After the patient leaves the surface of the aluminum film 103, the hollow rod 101 is manually closed to make the two close to each other. At this time, the scissor-type telescopic frame 104 shrinks accordingly to reduce the volume of the stretcher assembly 1. The portable cooling stretcher significantly improves the cooling speed and efficiency, and can effectively reduce the core body temperature of heat stroke patients in a short time, reducing the risk of worsening of the disease. At the same time, the portable design and the use of rechargeable batteries enable the device to be quickly deployed in emergency situations, thereby improving the efficiency of treatment. In addition, the application of the control chip enables the device to automatically adjust the cooling effect according to the real-time body temperature changes, avoiding the problem of excessive or insufficient cooling, thereby improving the comfort and safety of the patient. Among them, the semiconductor refrigeration sheet 2 is the core component for cooling, and it is necessary to select suitable power and size, for example: the power range is 30W to 100W, for example: the length and width are 40mm x 40mm to 60mm x 60mm, so as to ensure that it can be easily integrated into the portable cooling stretcher while cooling quickly. In order to improve the cooling efficiency, the contact area between the cold surface of the semiconductor refrigeration sheet 2 and the aluminum film 103 of the stretcher needs to be increased during design to ensure good heat conduction. Specifically, the contact area between the cold surface and the aluminum film 103 should reach at least 200cm 2 , to maximize the heat exchange effect; The control chip can automatically adjust the working state of the semiconductor refrigeration plate 2 according to the feedback signal of the body temperature sensing device, i.e., the thermometer body 4. The control chip has a temperature setting function. The user can set the target temperature through simple buttons or a touch screen interface or remote input. For example, the setting range is 18°C ​​to 25°C. In addition, the control chip should have a timing function. The user can set the cooling time, for example, 1 hour, 2 hours, etc., so as to facilitate flexible use in different situations.

[0023] like Figure 1-Figure 5 As shown, an electric winding reel is provided inside the hollow rod 101, and a thermometer wire 3 is wound on the surface of the electric winding reel, the end of the thermometer wire 3 penetrates the hollow rod 101 and is connected to a thermometer body 4, and a thermometer sleeve 5 is fixed to the outer wall of the hollow rod 101, the thermometer body 4 is connected to the control chip through the thermometer wire 3, and the thermometer body 4 is inserted into the thermometer sleeve 5; The specific operation is as follows: there are two hollow rods 101 in total, and an electric winding reel is arranged inside any hollow rod 101, which is powered by a battery. When the patient's body temperature needs to be detected in real time, the emergency personnel pull out the thermometer body 4 from the thermometer sleeve 5 and pull out the thermometer wire 3. At this time, the electric winding reel releases the part of the thermometer wire 3 wound on its surface, so that the thermometer body 4 expands the movable range, so that the thermometer body 4 can be inserted into the patient's armpit or neck for temperature measurement, and after the use of the thermometer body 4 is over, it is reinserted into the thermometer sleeve 5 to prevent it from being exposed for a long time. At the same time, the electric winding reel winds up the excess part of the thermometer wire 3 to prevent the line from being distributed in a messy manner.

[0024] like Figure 1-Figure 5 As shown, the stretcher assembly 1 further includes a vent hole 106, and the vent hole 106 is provided on the side of the surface of the load-bearing cloth 102 and the aluminum film 103 away from the semiconductor cooling sheet 2. The stretcher assembly 1 further includes a ventilation and cooling fan 107, and the bottom of the load-bearing cloth 102 is provided with a ventilation and cooling fan 107 directly below the vent hole 106; The specific operation is as follows: the load-bearing cloth 102 and the aluminum film 103 are provided with ventilation holes 106, so that when the patient's surface is covered with the cooling blanket 105, the internal space of the cooling blanket 105 is connected with the external space through the ventilation holes 106 and the ventilation and cooling fan 107. The hot air generated by the patient's fever and the moisture generated by cooling in the internal space of the cooling blanket 105 can be discharged to the outside through the ventilation and cooling fan 107.

The end of the elastic belt buckle 6 is engaged with the end of the female buckle 7, and two elastic belt buckles 6 and two female buckles 7 are respectively provided; The specific operation is as follows: when the cooling blanket 105 is not in use, it is rolled into a roll structure, wherein the semiconductor refrigeration sheet 2 inside the cooling blanket 105 is in a long strip structure and is evenly distributed, so that the semiconductor refrigeration sheet 2 can be rolled into a roll structure together with the cooling blanket 105, and the elastic strap buckle 6 is snap-connected with the female buckle 7 to fix the rolled structure of the cooling blanket 105 to prevent the cooling blanket 105 from being unfolded at will, so that the emergency personnel can move quickly with the stretcher assembly 1.

[0026] In summary, when the portable cooling stretcher is used, the hollow rods 101 are first manually separated from each other so that the load-bearing cloth 102 and the aluminum film 103 are unfolded, and the scissor-type telescopic frame 104 is then extended. When the heat stroke patient lies on the aluminum film 103, the scissor-type telescopic frame 104 is unfolded to support the patient from the bottom of the load-bearing cloth 102, so as to prevent the load-bearing cloth 102 from excessively sinking due to the patient's gravity. After the patient lies down, the cooling blanket 105 is manually covered on the patient's surface. At this time, the semiconductor cooling sheet 2 is respectively located at the front chest and back of the human body, and the emergency personnel insert the thermometer body 4 into the patient's armpit or neck. According to the patient's body temperature detected by the thermometer body 4, the battery supplies power to the semiconductor cooling sheet 2 to make its cold surface cool to cool the patient's body temperature. When the patient's surface is covered with the cooling blanket 105, the internal space of the cooling blanket 105 is connected to the external space through the vent 106 and the ventilation and cooling fan 107. The hot air generated by the patient's fever and the moisture generated by cooling in the internal space of the cooling blanket 105 can be discharged to the outside through the ventilation and cooling fan 107.
