Problems solved by technology

However, in the specific heating process, since a single heating element is used to heat the entire heating pad, the heating power provided by the heating element for each position of the heating pad is consistent, but the heating effect of different areas of the heating pad may be different, so This heating method will cause the different regions of the heating pad to exhibit different temperatures, making the surface of the heating pad uneven in temperature

Embodiment 1

[0045] refer to figure 1 , an emergency-type medical electric heating pad multi-zone temperature control system, including at least two heating elements 2 for heating different areas of the electric heating pad, a temperature detection unit 4 for detecting the temperature of the heating area, and a temperature detection unit 4 for adjusting the heating element 2 The heating efficiency power adjustment unit 3 and the feedback adjustment unit 1 for outputting a power adjustment signal to change the heating efficiency of the heating element 2 according to the temperature detection value of each heating area; heating different areas of the electric heating pad through a plurality of heating elements 2 , improve the heating efficiency, and also make the temperature uniformity on the surface of the electric heating pad better.

[0046] The heating element 2 is set as a carbon fiber heating sheet. In this embodiment, the electric heating pad is arranged in a rectangular shape, and t...

Embodiment 2

[0055] refer to figure 2 , a method for controlling the temperature of a medical electric heating pad, applied to the temperature control of a single heating area of ​​an electric heating pad in an embodiment, the method includes the following steps carried out in sequence:

[0056] The initial temperature difference, the steady-state temperature difference and the target temperature of the outer surface of the electric heating pad are preset according to empirical values; the initial temperature difference represents the difference between the internal temperature of the electric heating pad and the external temperature when the electric heating pad starts to heat up, and the steady-state temperature difference represents the temperature of the electric heating pad for a certain period of time The difference between the internal temperature of the electric heating pad and the external temperature is understandable. Since the temperature of the sponge layer and the artificial ...

Embodiment 3

[0064] A medical heating device, which is a device with a temperature control system in Embodiment 1 or a device applying the temperature control method in Embodiment 2.

[0065] By adopting the above technical solution, the device can provide a stable and uniform temperature environment for patients.

Abstract

The invention relates to a multi-zone temperature control system for an emergency medical electric heating pad, and belongs to the technical field of medical electric heating pads. The system comprises the following parts including at least two heating elements used for heating different areas of the electric heating pad; a temperature detection unit used for detecting the temperature of the heating areas; a power adjustment unit used for adjusting the heating efficiency of the heating elements; and a feedback adjustment unit used for outputting a power adjustment signal according to the temperature detection value of each heating area to change the heating efficiency of the heating elements. The heating in the different areas of the electric heating pad through a plurality of heating elements improves the heating efficiency and also makes the temperature uniformity on the surface of the electric heating pad better.

Description

technical field [0001] The invention relates to the technical field of medical electric heating pads, in particular to a multi-zone temperature control system for emergency medical electric heating pads. Background technique [0002] Medical heating pad is a common medical device, which is generally used to prevent patients from hypothermia during surgery or during first aid and transfer. [0003] Existing medical heating pads generally use a single heating element to heat the entire heating pad, and use multiple temperature sensors to monitor the temperature of different positions of the heating pad. However, in the specific heating process, since a single heating element is used to heat the entire heating pad, the heating power provided by the heating element for each position of the heating pad is consistent, but the heating effect of different areas of the heating pad may be different, so This type of heating can cause different regions of the heating pad to exhibit dif...
