Abstract
Description
Technical Field
[0001] The present invention belongs to the technical field of medical devices, and in particular relates to a bidirectional body temperature regulating blanket. Background Art
[0002] Children, especially infants and young children, are highly sensitive to temperature and have relatively weak thermoregulatory mechanisms. Precise temperature control is particularly important in certain medical situations, such as fever or the need for surgical procedures. Persistent high fever can lead to a range of serious complications in infants and young children, such as increased cardiac workload, increased oxygen consumption, and cerebral hypoxia and edema. Furthermore, infants and young children are prone to dehydration during a fever and may even experience serious conditions such as febrile seizures. Therefore, effective cooling measures are crucial for children with persistent high fever during medical care, as this helps protect their brain tissue and minimize damage to vital organs.
[0003] Traditional cooling methods, such as using cool towels or fever-reducing patches, have the disadvantages of small cooling area and slow cooling effect. Although cooling caps have appeared in recent years and are used to a certain extent for physical cooling of the head in clinical practice, their shape is fixed and cannot be adjusted according to the size of the child's head, and they usually fit poorly. At the same time, the use of built-in ice bags or cooling bags for cooling requires frequent replacement of the built-in items, which is more troublesome to use. In addition, the child's body temperature needs to be raised before and after surgery and during specific treatments to achieve precise control of the body temperature. Therefore, it is necessary to develop a two-way temperature control blanket suitable for whole-body cooling or heating of children, which can provide a more uniform and faster cooling or heating effect.

[0024] The host 1 is internally provided with a buzzer and a temperature detector, the temperature detector and the buzzer are electrically connected with the single-chip microcomputer, and the temperature detector is arranged outside the liquid outlet of the heat exchange container. The model of the temperature detector in the embodiment of the present application is Ds18b20.
[0025] The connection circuit diagram of the buzzer and the temperature detector in the embodiment of the present application is shown in Figure 7 Through the design of the buzzer and the temperature detector, the temperature of the liquid at the liquid outlet can be detected by the temperature detector, after the temperature detector detects the temperature of the liquid, the detected temperature is transmitted to the single-chip microcomputer through a digital signal, the single-chip microcomputer converts the voltage signal into an analog signal through a digital-to-analog conversion module, and the analog signal is displayed on the display screen 3 to display the temperature. Figure 8 The circuit diagram of the display screen 3 is shown in Figure 9When the temperature detector detects that the liquid temperature is too high or too low, it sends a signal to the microcontroller, which in turn sends a signal to the buzzer, which sounds an alarm to alert medical staff of the potential danger of excessively high or low temperatures. The interaction of these components ensures precise temperature increase and decrease without causing burns or frostbite.
[0026] The main unit 1 is provided with a first knob 9 and a second knob 10, which are electrically connected to the first and second sliding resistors, respectively. The design of the first and second knobs 9 and 10 can adjust the heating and cooling rates, making the heating or cooling time controllable to meet different temperature control requirements.
[0027] The liquid in the heat exchange container is water. In the embodiment of the present invention, the liquid in the heat exchange container is preferably water, and ethanol, ethylene glycol, glycerol, mineral heat transfer oil, or other liquids can also be used, and the specific design can be based on the needs.
[0028] The main body 2 in the embodiment of the present invention is further provided with a reset button 11 (K1). Due to the design of the reset button 11, when a failure occurs in the host 1, the function of the host 1 can be restored by pressing the reset button 11.
[0029] When the child's temperature needs to be raised or lowered quickly, the child is laid flat on the blanket 2, and then the plug end of the power cord with a plug is directly plugged into the AC mains socket. Specifically, when the child's body temperature needs to be raised, the first button 4 (K2) and the third button 6 (K4) are pressed at the same time. The single-chip microcomputer detects a low level, proving that the button is pressed. The single-chip microcomputer outputs to P1.0 and P1.2 respectively, and the first relay KA1 and the third relay KA3 detect the signal. The normally open terminals of the first contactor KM1 and the third contactor KM3 are closed, and VSS and the first contactor KM1 and the third contactor are connected. The contactor KM3 is connected to control the output of the low-voltage circuit. When the low-voltage circuit VSS is connected to the first contactor KM1, the heater R2 is turned on to heat the liquid in the heat exchange container. After the liquid is heated to a suitable temperature, the circulation pump P1 is turned on to push the liquid into the circulation pipeline through the liquid outlet, and then enters the heat exchange container through the liquid inlet. The liquid circulates in the circulation pipeline, thereby increasing the temperature of the blanket body and thus the temperature of the child. At the same time, since the low-voltage circuit VSS is connected to the third contactor KM3, the air pump P2 is turned on to vent the inflation pipeline 8. Inflation increases the expansion of the inflation pipe 8, thereby improving the comfort of the patient lying on the blanket; and when the child's body temperature needs to be lowered, the second button 4 (K3) and the third button 6 (K4) are pressed at the same time, the single-chip microcomputer detects a low level, proving that the button is pressed, and the single-chip microcomputer outputs to P1.1 and P1.2 respectively, the second relay KA2 and the third relay KA3 detect the signal, the normally open terminals of the second contactor KM2 and the third contactor KM3 are closed, VSS is connected to the second contactor KM2 and the third contactor KM3, thereby controlling the output of the low-voltage circuit. When the low-voltage circuit VSS and the third When the second contactor KM2 is connected, the cooler TEC turns on to cool the liquid in the heat exchange container. After the liquid is cooled to the appropriate temperature, the circulating pump P1 turns on, pushing the liquid through the liquid outlet into the circulation pipeline, and then through the liquid inlet to the heat exchange container. As the liquid circulates in the circulation pipeline, the temperature of the blanket and the child is lowered. At the same time, due to the connection between the low-voltage circuit VSS and the third contactor KM3, the air pump P2 turns on to inflate the inflation pipeline 8, thereby increasing the expansion of the inflation pipeline 8 and improving the comfort of the patient lying on the blanket. During the heating or cooling process, the temperature detector monitors the liquid temperature in real time. If the temperature detector detects that the liquid temperature is too high or too low, it sends a signal to the microcontroller, which in turn sends a signal to the buzzer, which sounds an alarm to alert medical staff that the temperature is too high or too low, which may be dangerous.
