Device for spraying and sucking hot water on injured animal surface model in self-control mode

Abstract

Provided is a device for spraying and sucking hot water on an injured animal surface model in a self-control mode. A hot water generation source is arranged in a box, and an electric heating pipe, a heat source temperature sensor and a water level sensor are arranged in the hot water generation source. A hole is formed in the hot water generation source, an electromagnetic valve is arranged on the hole, the lower end of the electromagnetic valve is provided with a hot water spraying hose, the hot water spraying hose is connected with an injury cup, silicon rubber is arranged on the rim of an injury cup, an injury supporting plate used for fixing the animal surface is arranged on the lower portion of the rim of the injury cup, a suction pipeline is arranged in the silicon rubber and is connected with a suction collection bottle, a hot water spraying nozzle is arranged in the injury cup, negative pressure suction is started in the injury cup during injuries, hot water after the injuries is quickly sucked, spraying and suction are synchronous, and water temperature effectively keeps uniform. Premise control of hot water injury time, the area and temperature is achieved. Operation is simple and convenient to achieve, injured edges are clear, repeatability is good, scald surfaces are consistent on the same condition, and reference is provided for burn and scald wound healing and medication research.

Description

technical field [0001] The invention relates to the technical field of making animal body surface models for burn wound treatment research experiments, in particular to a device for automatically controlling hot water spraying and inhalation to injure animal body surface models. Background technique [0002] At present, there are still a series of problems in the treatment of diseases caused by heat source burns invading the skin, such as: the coverage of burn wounds, various complications caused by the persistence of wound necrotic tissue, and the progressive deepening of wounds. It is an urgent need to study the pathophysiological process and curative effect mechanism of burns. However, many experiments cannot and should not be conducted on humans. Therefore, animal models of burns are established to study the development and evolution of various body systems and local wounds after burns. An ideal animal model should be reproducible and even standardized, otherwise it will...

Problems solved by technology

[0002] At present, there are still a series of problems in the treatment of diseases caused by heat source burns invading the skin, such as: the coverage of burn wounds, various complications caused by the persistence of wound necrotic tissue, and the progressive deepening of wounds. To study the pathophysiological process and curative effect mechanism of burns is an urgent need for the treatment of burns. However, many experiments cannot and should not be conducted on humans. Therefore, animal models of burns are established to study the development and evolution of various body systems and local wounds after burns.

An ideal animal model should be reproducible, or even standardized, otherwise it will directly lead to distortion of test results

[0003] However, at present, the establishment of animal body surface models mainly relies on traditional napalm burns or boiling water scalds. The definition of the depth and completeness of the wound is not accurate, and there is a certain gap between the boiled water scalds in real life, and steam needs boiling water to generate , not suitable for burn experiments below 100°C

Moreover, factors such as the time, area and temperature of napalm burns or boiling water scalds cannot be accurately controlled.

[0004] The edge of the wounded animal surface model is not clear and the repeatability is poor
