[0001] The invention belongs to the field of medical equipment, in particular to a medical carbon fiber heating device, and relates to a medical carbon fiber heating device. Background Art

[0002] A medical heating blanket is a heating device specially designed for use in medical environments. The heat generated by the heating blanket is used to warm the patient's body to prevent hypothermia. Its main functions include maintaining body temperature. During surgery, anesthesia or serious illness, a medical heating blanket helps maintain the patient's normal body temperature and prevent hypothermia; improving comfort. Through moderate temperature control, patients can feel comfortable during treatment or recovery and reduce anxiety and discomfort; and promoting blood circulation. Appropriate heat can promote blood circulation and help the body recover better. It is a commonly used auxiliary tool during surgery, in ambulances, and in intensive care.

[0003] Existing medical heating blankets are of fixed size. When facing patients of different heights, body lengths and body shapes, fixed-size heating blankets are not suitable for the body shapes and needs of all patients, which will cause some patients to not be well covered and warmed. For patients with larger or smaller bodies, fixed-size heating blankets may cause uneven heating effects, and some parts may be exposed and feel cold, affecting overall comfort. In different medical occasions or situations, the patient's condition may be different, and the fixed size cannot be flexibly adjusted to meet different needs, which limits the usage scenarios.

[0025] The present invention is further described in detail below in conjunction with the accompanying drawings.

[0026] Reference Figure 1-3, is a medical carbon fiber heating device disclosed in the present invention, including a thermostat 1, a temperature sensor 2, a heating blanket 3 and an adaptor 4. The thermostat 1 is used to control the surface temperature of the heating device to stabilize it at a temperature value set by the user. It works in an electric heating mode, converting electrical energy into thermal energy to provide heat for the patient. The temperature sensor 2 is used to measure the body temperature of the patient during surgery. It is a temperature measuring device for reference by medical staff. The temperature sensor 2 partly adopts a medical temperature sensor, which is easy to use and has high accuracy. The heating blanket 3 is used to maintain the body temperature of the patient or the surgical patient. When using it, it should be noted that the patient should lie flat on the heating blanket, and try to lie in the center of the heating blanket. The patient's body must be covered on the sensor icon of the heating blanket. The heating blanket should be fully unfolded (avoid folding) and laid under the patient or covering the patient's body. Avoid direct contact with the wound. When using the heating device at the distal end of the arterial clamping site, the operator should monitor the patient's skin heating every 15 minutes. To avoid potential risks such as burns, if any signs of burns are found, the heating function of the equipment must be stopped immediately, otherwise it will cause thermal burns to the patient. Do not use heating equipment on ischemic parts of limbs, otherwise it may cause thermal burns to the patient. When the user turns on the power switch 17 and the working switch of the thermostat 1, the alarm display component of the thermostat 1 will perform a self-check, all indicator lights will be lit, the two display windows will display the software version number, and the speaker will make a sound once. After completing the above work, the power-on self-check is completed. If the indicator light status is normal, it means that the machine has completed the preparation work and can proceed to the next step. If there is no further operation, the thermostat 1 will enter the automatic heating mode, and the working status defaults to the set temperature when it was last shut down, and it will adjust the heating automatically.

[0027] Reference Figure 1-3 In this embodiment, the adapting component 4 is arranged on the outside of the heating blanket 3, and the adapting component 4 includes a plurality of pull-out members, which are used to adjust the length of the heating blanket 3. The pull-out members include two longitudinal rope-threading cloths 41 and two transverse rope-threading cloths 42. The two longitudinal rope-threading cloths 41 are both provided with longitudinal pull-out ropes 43, and the two transverse rope-threading cloths 42 are both provided with transverse pull-out ropes 44. The transverse pull-out ropes 44 and the longitudinal pull-out ropes 43 are pulled out of the transverse rope-threading cloths 42 and the longitudinal rope-threading cloths 41, and the transverse pull-out ropes 44 and the longitudinal pull-out ropes 43 are tied into a knot, so as to reduce the longitudinal or transverse size of the heating blanket 3. The adapting component 4 also includes a dismantling part, which is used to replace the cloth used on the surface of the heating blanket 3. The dismantling part includes a plurality of knots 45 and a plurality of knot buckles 46.

A heating device connection line 15 is connected to one side of the thermostat 1 through a heating device connector. A control area 16 is arranged above the thermostat 1. The control area 16 has two heating modes, namely a manual heating mode and an automatic heating mode. The manual heating mode can be adjusted within the range of 0% to 100% of the output power, and the minimum adjustment step is 10%; the automatic heating mode can be heated according to the temperature setting, and the minimum temperature setting step is 0.1°C. A power switch 17 is arranged on one side of the thermostat 1. The power supply voltage of the thermostat 1 when working normally is: AC 220V, 50Hz~60Hz; ambient temperature range: +18°C~+30°C; ambient humidity range: relative humidity ≤80% ; Atmospheric pressure range: 860hPa~1060hPa.

[0030] Reference Figure 1-3 In this embodiment, before each use, check whether the surface of the heating device is mechanically damaged, whether the power socket and the power connection line 14 are aging or damaged; when the power of the heating device cannot be connected, check whether the power socket has electricity, whether it is loosely connected, whether the heating device connection line is loosely connected, whether the power switch 17 is turned on or the fuse is broken. The temperature setting range of the thermostat 1 is at least: 33℃~39℃, but should not exceed 41℃. The difference between the average temperature of the contact surface and the average temperature of a single test point should not exceed ±1.5℃. Under normal working conditions, the time required for the medical electric heating pad to heat from (23±2)℃ to 37℃ should be ≤40 minutes.

[0031] When in use, install the thermostat 1, connect the heating device connection line 15, the power connection line 14 and the thermostat 1, turn on the AC power of the thermostat 1, and turn on the power switch 17 and the working switch in turn, turn on the heating blanket 3, lay it flat on the patient's body with the front side (the side with the outlet and the mark) facing up, and tighten and fix it with a bandage, insert the heating device connection line 15 into the plug of the heating blanket 3, if the patient does not need to cover the whole body to keep warm, or according to the different heights and lengths of some patients, the longitudinal draw cord 43 can be pulled out of the longitudinal rope cloth 41 to cover the waterproof layer 33 or the carbon fiber heating layer 3 1 and the protective layer 32 are shortened, and a slipknot is tied at one end where the longitudinal pull rope 43 and the longitudinal rope cloth 41 are passed through, so that the length of the heating blanket 3 can be fixed. Similarly, the transverse pull rope 44 is pulled out of the transverse rope cloth 42 to shorten the width of the waterproof layer 33 or the carbon fiber heating layer 31 and the protective layer 32, and a slipknot is tied at one end where the transverse pull rope 44 and the transverse rope cloth 42 are passed through, so that the width of the heating blanket 3 can be fixed. The size of the heating blanket 3 can be adjusted according to the patient's body shape, height, usage and patient status, thereby improving the applicability, flexibility and comfort of the heating blanket 3.

[0032] For some people who are allergic to the waterproof layer 33, the patient can be asked in advance whether he has a history of allergy to a certain material, and a waterproof layer 33 of a material to which he is not allergic can be selected to cover the protective layer 32 of the heating blanket 3 for use.
