Automatic time control and pressure regulation scald apparatus

Abstract

The invention relates to a scald apparatus for producing a scald wound model of an animal, in particular to an automatic time control and pressure regulation scald apparatus. The scald apparatus comprises a vapour generator and a vapour spray head, wherein a pressure regulating valve, a thermometer and a pressure gauge are arranged on the vapour generator; and the vapour generator is communicated with the vapour spray head by a vapour conveying pipe, an electromagnetic valve and a vapour-water discharge valve are arranged on the path of the vapour conveying pipe, the vapour-water discharge valve is arranged between the electromagnetic valve and the vapour spray head, the electromagnetic valve is in circuit connection with a time controller, and the time controller is started by a time controller switch. For further improvement, the scald apparatus also comprises a scald mould which can effectively fix the formulated scald area of the animal. Compared with the prior art, the automatic time control and pressure regulation scald apparatus of the invention can accurately regulate the scald time, and can regulate and supervise the vapour pressure at real time; and the safety performance is high, the maneuverability is good, and the surface of scald wound produced by the automatic time control and pressure regulation scald apparatus has regular boundary, uniform shape, accurate depth and good repeatability.

Description

Technical field: [0001] The invention relates to a scald instrument for preparing animal scald wound models, in particular to an automatic time-controlled and pressure-regulated scald instrument. Background technique: [0002] Establishing a standard animal burn wound model is the basis and premise for carrying out burn wound repair research and evaluating drug efficacy. A standardized animal burn wound model means that the size, shape, and depth of the burn wound are made with high accuracy, consistency and repeatability. To make a standardized animal burn wound model requires that the burn (scald) wound instrument for making the model must be It has constant pressure and temperature, accurate burn time, and the production of the model will not be affected by the movement of the animal during the burn. The instrument should also be suitable for the production of scald wound models of various parts of small and medium-sized animals (such as rabbit ears, the side of the mouse...

Problems solved by technology

However, this type of equipment has the following disadvantages: after the burn time is up, the hot head will be manually removed, making it difficult to make consistent burn times for making multiple burn wound models; Manually controlled metal irons may vibrate during burns, especially when animals move, which will cause changes in the pressure of the metal iron and the contact surface with the skin. These unstable factors lead to the shape of the burn wound Irregular, uneven depth

The scalding time of the existing steam scalding equipment is controlled by manually cutting off the steam, and it is difficult to keep the scalding time consistent when making multiple scald wound models; in addition, the steam pressure of the existing steaming equipment cannot be adjusted according to needs and can only be adjusted at one time. work under a relatively high pressure (900mmHg), and there are no collection and drainage measures for the water droplets generated by the steam, which is not conducive to control, and is easy to injure the animals and operators; moreover, the animals need to be placed on the scald support when they are scalded , it is not easy to align and fix the pre-scald point with the scald hole, and the slight shaking of the animal during the scald will also cause the animal to shift, resulting in irregular shape and uneven depth of the scald wound

[0006] Due to the influence of the above factors, the existing heat (steam) scalding equipment cannot fully meet all the conditions required for making a standardized animal scald wound model, which affects the accuracy of the animal scald wound model, thereby affecting the research results
