Description

Technical Field

[0001] The present invention relates to the technical field of material testing, and in particular to a method for mass-producing functional testing of finished products of heat compress patches. Background Art

[0002] In modern society, people's pursuit of health and quality of life is increasing. Hot compress, as a traditional physical therapy method, has many benefits such as relieving pain, promoting blood circulation, and relaxing muscles. With the development of science and technology, hot compress patches came into being. Traditional hot compress methods may have problems such as inconvenient operation and difficult temperature control, while hot compress patches provide a more convenient and efficient solution.

[0003] Early hot compress patches may have some technical limitations, such as short heating duration, uneven temperature, and poor adhesion leading to easy falling off. However, with the continuous advancement of materials science and technology, the performance of hot compress patches is gradually improving.

[0004] For example, the existing Chinese patent with patent number 202210925256.8 discloses a method for testing the temperature duration of a hydrogen-rich hot compress patch. This scheme turns on the constant temperature heating box, uses the heater to heat the water so that the flat supporting area of ​​the box cover reaches the human body surface temperature, and then places the hydrogen-rich hot compress patch on it after laying a wet patch and detecting the temperature. The temperature change is used to determine the duration to determine whether the hydrogen-rich hot compress patch is qualified, and a variety of auxiliary structures are used to improve the accuracy and convenience of the test.

[0005] However, the above patent has the following problems: 1. The solution's analysis of temperature performance mainly focuses on the temperature change over time, the rate of heating, the duration of temperature maintenance, etc., but does not involve the detection of the heating temperature range, temperature uniformity, etc., which may lead to an incomplete evaluation of the heating performance of the hot compress patch, and an inability to accurately understand its performance within a specific temperature range and whether it meets the requirements. As a result, in actual applications, it may not be possible to generate heat continuously and effectively or the local temperature may be too high or too low, affecting the use effect and safety.

[0006] 2. This program conducts relevant tests and analyses on the heating temperature of the hot compress patch, but the testing of the hot compress patch also includes other aspects, such as viscosity and leakage degree. Viscosity will affect the fixing effect of the hot compress patch during use. If the viscosity is insufficient, it may cause it to fall off, affecting the user experience. The leakage degree is related to the quality and safety of the product. Severe leakage may cause adverse effects or even harm to the user. When conducting a comprehensive evaluation of the hot compress patch, if these factors are not comprehensively considered, it may not be possible to ensure that the performance and quality of the product meet the requirements.

By selecting multiple time points for testing, the temperature change curve of the hot compress patch can be understood in detail, and key information such as its heating rate and thermal insulation effect can be mastered, providing data support for product optimization and improvement.

[0043] It should be noted that the specific analysis method of the surface temperature of each hot compress patch at each time point at the set temperature is as follows: a number of hot compress patches are extracted from the finished hot compress patches as spot check samples, and they are evenly divided into a number of groups, which are recorded as each group of hot compress patches, and one group is selected as a temperature test sample, which is recorded as each hot compress patch tested at the set temperature, and each hot compress patch tested at the set temperature is placed in a constant temperature box, and the temperature of the constant temperature box is set to the set temperature.

[0044] The second step is to test the surface temperature of each hot compress patch at each time point according to the set temperature to analyze the heating rate of the hot compress patch at the set temperature. This can accurately understand how fast the hot compress patch heats up in a specific temperature environment, which helps to evaluate whether the product performance meets expectations. The heating rate can be used to determine whether the hot compress patch can quickly achieve the ideal hot compress effect and provide timely warmth to the user.

[0050] It should be noted that the low-temperature environment temperature is generally slightly higher than the room temperature but still significantly lower than the normal body temperature of the human body, which may be around 20℃ to 30℃. This can simulate relatively cool environmental conditions. The high-temperature environment temperature is usually close to or slightly higher than the temperature at which the human body can feel obvious warmth, which may be around 40℃ to 60℃. This is to examine the performance of the hot compress patch under higher temperature conditions.

[0051] It should be noted that the specific analysis method for the temperature compliance of the hot compress patch in the low-temperature environment and the high-temperature environment is as follows: the thermostat is set to simulate the low-temperature environment and the high-temperature environment according to the set low temperature and high temperature respectively, and the surface temperature, heating rate and temperature range of each hot compress patch at each time point are tested according to the set temperature to obtain the surface temperature, heating rate and temperature range of each hot compress patch in the low-temperature environment and the high-temperature environment; and the temperature compliance of the hot compress patch in the low-temperature environment and the high-temperature environment is obtained by analyzing the temperature compliance of the hot compress patch at the set temperature, which is recorded as .

[0052] The sixth step is to obtain the temperature evaluation coefficient of the hot compress patch based on the temperature compliance of the hot compress patch under the set temperature and the temperature compliance of the hot compress patch under low temperature environment and high temperature environment.
