Technical Field

[0001] The utility model relates to the technical field of medical care, and particularly relates to a temperature-changing device. Background Art

[0002] In modern medical care, the control of a patient's body temperature is an important link. Generally, a temperature-changing blanket is placed on the bed to control the patient's body temperature. The existing temperature-changing blanket includes a blanket with a circulating water path, an inlet and outlet water pipe, and a heat exchange device. The heat exchange device is connected to the blanket with the circulating water path through the inlet and outlet water pipe, and the temperature is adjusted by heating and cooling the circulating water through the heat exchange device.

[0003] However, it is found in use that the above-mentioned temperature-changing blanket still has the following defects: the temperature-changing efficiency is low by the water circulation method, and bacteria are easily bred in the water circulation pipeline and are not easy to clean, so that the temperature-changing blanket instead becomes a pollution source. Summary of the Utility Model

[0004] In view of this, the utility model provides a temperature-changing device to solve the problems of low temperature-changing efficiency by water circulation and easy breeding of bacteria.

The heat exchange device is used for changing the phase of the circulating refrigerant to realize heating or cooling of the human body.

[0009] Beneficial effects: Compared with water heating and cooling by absorbing and releasing energy, the refrigerant including at least one halogenated hydrocarbon heats up and cools down by phase change. Therefore, the temperature-changing speed is faster, the human body temperature can be adjusted more quickly, and a faster response speed can be achieved for the change of the human body temperature. Moreover, because the temperature-changing speed is faster and the efficiency is higher, a buffer layer can be added between the temperature-changing device and the human body during use without worrying about not being able to provide enough temperature, thereby improving the user experience when using the temperature-changing device. At the same time, bacteria and other microorganisms cannot survive in the refrigerant, so the breeding of bacteria and microorganisms can be avoided. In this way, the temperature-changing device does not need to regularly replace and clean the circulating pipeline, and the use efficiency of the temperature-changing device is improved.

[0013] Advantageous effects: By using a metal pipe to make the variable-temperature pipeline, the risk of the refrigerant leakage caused by the variable-temperature device being punctured or cut by sharp objects during use is avoided, and the safety of the variable-temperature device during use is improved.

[0014] In an alternative embodiment, the variable-temperature pipeline includes multiple groups of parallel arranged circulation pipelines, and adjacent segments of the circulation pipelines are connected by deformable elbows.

[0015] Advantageous effects: The variable-temperature pipeline formed by connecting the parallel arranged circulation pipelines through the deformable elbows has the ability to bend and roll.

[0016] In an alternative embodiment, the variable-temperature device includes:

[0017] An auxiliary heating device, which is arranged inside the variable-temperature body and is used for auxiliary heating when the refrigerant heats the human body.

[0019] In an alternative embodiment, the auxiliary heating device is an electric auxiliary heating device;

[0020] And / or, the auxiliary heating device and the variable-temperature pipeline are arranged alternately.

[0021] Advantageous effects: Arranging the auxiliary heating device and the variable-temperature pipeline alternately makes the temperature increase and decrease of the variable-temperature body more uniform.

[0022] In an alternative embodiment, the variable-temperature device includes:

[0023] A temperature sensor, which is arranged on the variable-temperature body;

[0024] A control device, which is connected to the temperature sensor and the heat exchange device and is adapted to control the operation of the heat exchange device according to the detected temperature of the temperature sensor.

[0036] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are some, but not all, of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0037] The following will describe the embodiments of the present utility model in conjunction with Figure 1 , the embodiments of the present utility model will be described.

[0038] According to an embodiment of the present utility model, a temperature-changing device is provided for placing on a bed to adjust the human body temperature, including: a temperature-changing body 1; a temperature-changing pipeline 101 disposed inside the temperature-changing body 1, a refrigerant is provided in the temperature-changing pipeline 101, and the refrigerant includes at least one halogenated hydrocarbon; a heat exchange device 3 disposed outside the temperature-changing body 1, the heat exchange device 3 is connected to the temperature-changing pipeline 101 through a connecting pipeline 2, and the refrigerant circulates in the temperature-changing pipeline 101, the connecting pipeline 2, and the heat exchange device 3, and the heat exchange device 3 is used to phase-change the circulating refrigerant to achieve heating or cooling of the human body.

[0039] Compared with water that absorbs and releases energy to increase and decrease temperature, the refrigerant including at least one halogenated hydrocarbon increases and decreases temperature through phase change. Therefore, the temperature-changing speed is faster, the human body temperature can be adjusted more quickly, and a faster response speed can be achieved for the change in the human body temperature. Moreover, because the temperature-changing speed is faster and the efficiency is higher, a buffer layer, such as a quilt, can be added between the temperature-changing device and the human body during use to improve comfort without worrying about not being able to provide sufficient temperature, thereby improving the user experience of the personnel when using the temperature-changing device. At the same time, bacteria and other microorganisms cannot survive in the refrigerant, so the breeding of bacteria and microorganisms can be avoided. In this way, the temperature-changing device does not need to regularly replace and clean the refrigerant pipeline, improving the use efficiency of the temperature-changing device.

[0040] The refrigerant in this embodiment is chlorofluorocarbon, hydrochlorofluorocarbon, or hydrofluorocarbon, and specifically can be trichlorofluoromethane, chlorodifluoromethane, 1,1,1,2-tetrafluoroethane, etc., which are not specifically limited here.

[0041] In this embodiment, the temperature-changing pipelines 101 are uniformly arranged inside the temperature-changing body 1, making the temperature distribution of the temperature-changing body more uniform. When a person lies on the temperature-changing device, the felt heating or cooling will also be relatively uniform, improving the comfort of the personnel.

[0042] There are no excessive restrictions on the specific material setting of the variable-temperature pipeline 101. In this embodiment, the variable-temperature pipeline 101 is made of a metal pipe. By using a metal pipe to make the variable-temperature pipeline 101, the risk of refrigerant leakage caused by the puncture or cutting damage of the variable-temperature device by sharp objects during use is avoided, and the safety of the variable-temperature device during use is improved. As an alternative implementation, the variable-temperature pipeline 101 can also be made of a PVC pipe, a rubber pipe, etc.

[0043] As Figure 1 shown, the variable-temperature pipeline 101 includes multiple groups of parallel arranged circulation pipelines 1011, and adjacent circulation pipelines 1011 are connected by deformable elbows 1012. The variable-temperature pipeline 101 formed by connecting the parallel arranged circulation pipelines 1011 through the deformable elbows 1012 has the ability to be bent and curled. While meeting the need to fit special human body postures during the use of the variable-temperature device, it also facilitates the storage of the variable-temperature device. As an alternative implementation, it can also be that the variable-temperature pipeline 101 only includes multiple groups of parallel arranged circulation pipelines 1011, and adjacent circulation pipelines 1011 are not connected together.

[0044] In this embodiment, the variable-temperature device further includes an auxiliary heating device 102, which is arranged in the variable-temperature body 1, and the auxiliary heating device 102 is used for auxiliary heating when the refrigerant heats the human body. By adding the auxiliary heating device 102, the defect that the heating efficiency of the refrigerant including halogenated hydrocarbons is lower than the refrigeration efficiency can be solved. In an alternative implementation, the auxiliary heating device 102 can also not be provided.

[0045] In this embodiment, the auxiliary heating device 102 is an electric auxiliary heating device, such as an electric heating wire, or it can also be other devices that convert electrical energy into heat energy.

[0046] As Figure 1 shown, the auxiliary heating device 102 and the variable-temperature pipeline 101 are arranged alternately. The alternating arrangement of the auxiliary heating device 102 and the variable-temperature pipeline 101 makes the temperature rise and fall of the variable-temperature device more uniform.

[0047] The heat exchange equipment in this embodiment includes a compressor, a heat exchanger, and a throttling device. The heat exchange equipment and the variable-temperature pipeline 101 together form a heat exchange system that can both heat and cool, such as an air-conditioning system, to realize the phase change of the refrigerant to heat or cool the human body.

[0048] In this embodiment, the variable-temperature device further includes: a temperature sensor, which is arranged in the variable-temperature body 1; a control device 4, which is connected to the temperature sensor and the heat exchange equipment 3, and is adapted to control the operation of the heat exchange equipment 3 according to the detected temperature of the temperature sensor. The control device 4 controls the heat exchange equipment 3 according to the temperature information of the temperature sensor and adjusts the power of the heat exchange equipment 3 to ensure the stable temperature of the variable-temperature body 1. In an alternative implementation, the temperature sensor can also not be provided.

[0049] In this embodiment, multiple temperature sensors are provided and are distributed in different areas of the temperature-changing body 1. By providing multiple temperature sensors, the temperature of the temperature-changing body 1 can be monitored better, preventing problems such as local overheating or local overcooling.

[0050] Specifically, the temperature sensors can be evenly arranged inside the temperature-changing body 1, for example, specifically arranged in the gaps between the temperature-changing pipelines 101. As an alternative embodiment, it can also be that the temperature sensors are arranged on the upper surface of the temperature-changing body 1. In order to prevent affecting a person lying on the temperature-changing body 1, the temperature sensors can be arranged at the edges of the temperature-changing body 1.

[0051] In this embodiment, the temperature-changing device further includes a display device 401 for displaying the working state of the temperature-changing device. The display device 401 can display the working state of the temperature-changing device, facilitating the viewing and management by nursing staff. In an alternative embodiment, the display device 401 is a touch device, and the operator operates the temperature-changing device through the touch device.

[0052] In one embodiment, the temperature-changing device includes a wireless module, and the temperature-changing device is connected to the central control system through the wireless module. By providing a wireless module in the temperature-changing device and connecting the temperature-changing device to the central control system through the wireless module, remote management of the temperature-changing device by nursing staff is realized, the intelligent level of the temperature-changing device is improved, and centralized management and monitoring of the temperature-changing device are facilitated. As an alternative embodiment, it can also be that the temperature-changing device does not include a wireless module.

[0053] In this embodiment, the control device 4 further includes an operating device 402 for interacting with the control device 4 to control the operation of the temperature-changing device. Specifically, the operating device 402 can be control buttons.

[0054] In this embodiment, the temperature-changing body 1 is a temperature-changing blanket. In an alternative embodiment, the temperature-changing body 1 can also be a temperature-changing mattress, a temperature-changing pillow, a temperature-changing quilt, etc.

[0055] Although the embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by the appended claims.
