Embodiment 1

[0042] A scald instrument and a method for manufacturing burn wounds:

[0043] As attached figure 1 As mentioned, the entire automatic scald instrument is built with Arduino Mega2560 as the control center, including:

[0044] The human-computer interaction interface composed of Weinview MT6050i touch screen is used to input information, set parameters, display operation and detection information;

[0045] The actuator is composed of Oriental Motor Vexta BLHM015K-50 stepper motor and its driver, and IKO TU40C26A Z-axis precision positioning table (electric cylinder), which is used to control the rising and falling of the heating head and adjust the heating head applied to the animal Pressure

[0046] Pressure detection system composed of IMADA DS2-200N dynamometer;

[0047] Heating and temperature monitoring and control system, by OMRONG3PX-220EUN Power Controller single-phase power regulator, NAiS KT7 digital thermostat, 300W rated power hot runner with thermocouple heating tube and cu...

Embodiment 2

[0056] Example 2 is an animal experiment on the scald wound made by the apparatus of Example 1:

[0057] (1) Animal handling and modeling steps

[0058] As attached image 3 As shown, 6-week-old SPF male SD rats (220-240g) were selected for the experiment, provided by the Experimental Animal Center of Sun Yat-sen University. In the first part, 27 rats were included. According to the results of the preliminary experiment, 3 different burn temperature groups were set: 60℃, 80℃, 100℃ (the number of animals included in each group was n=9), and each temperature group was divided into 3 Pressure value group: 0.6N, 0.8N, 1.0N (the number of animals included in each pressure value n=3), the animals were randomly assigned. The burn time is uniformly set to 10s, and the diameter of the ironing head is uniformly 20mm. In the second part, two additional animals under 60℃, 0.6N, 10s conditions and two under 80℃, 0.8N, 10s conditions were added to test the consistency of shallow scald modeling...

Abstract

The problems that existing scald wound manufacturing is poor in accuracy, consistency and repeatability, and a mild scald model cannot be accurately manufactured are solved. An automatic animal scaldmodel making instrument is successfully developed by utilizing an Arduino intelligent hardware platform, accurate control of temperature, pressure, time and the like is realized, and a made wound surface model has good accuracy, consistency and repeatability. The scald instrument is characterized by comprising a temperature assembly, a pressure assembly, a controller connected with a digital intelligent power supply, a digital controller, a continuous digital manometer and a pressure power supply.

Description

Technical field [0001] The invention relates to the field of medical equipment, in particular to a scald instrument and a method of use. Background technique [0002] Using animal models of burns and scalds to verify experimental hypotheses is a key step in the study of burn wound healing. Compared with in vitro cell models, animal models test the effects of burns and scalds and interventions at the overall level and under the influence of multiple factors, which can better simulate the human body The occurrence and development of burns. In the past, the research on burn wound healing was limited by modeling technology, mainly using deep second-degree and third-degree animal scald models to study whether the wound can heal; however, burn wounds of different depths have different pathophysiological changes. It is necessary to extend the research to animal models of first-degree and superficial second-degree burns. Otherwise, it will be difficult to conduct more detailed studies s...
