Embodiment 1

[0025] Example 1, see figure 1 as shown,

[0026] see figure 1 , as shown in the figure, the smoke inhalation injury model device 100 includes a smoke chamber 110 , a pipe 120 , a hollow thermostat tube 121 and an injury chamber 130 . Corresponding two ends of the pipeline 120 are respectively connected with the smoke chamber 110 and the injury chamber 130 , and the hollow thermostat tube 121 is wound around the pipeline 120 .

[0027] see figure 1 The material selection of the smoke chamber 110 is not specifically limited. In this embodiment, preferably, the smoke chamber 110 is a pressure cooker. The selection of the pressure cooker is based on the following reasons: first, the airtightness of the pressure cooker is very good; secondly, as the gas in the pot continues to heat up, the movement of the gas molecules intensifies, the average speed of the molecules increases, and the force of the molecules hitting the wall When the pressure increases, the pressure in the pot ...

Embodiment 2

[0041] Example 2, see figure 2 as shown,

[0042] The smoke inhalation injury model device 200 has the same realization principle and technical effect as that of Embodiment 1. For a brief description, reference can be made to the corresponding content in Embodiment 1 for what is not mentioned in this embodiment.

[0043] The smoke inhalation injury model device obtained through the above design can basically solve the problems of simulating the fire smoke inhalation scene, the design structure is simple and easy to operate, but in line with the purpose of further improving its function, the designer made the smoke inhalation injury model device Further improvements were made.

[0044] see figure 2 , as shown in the figure, the smoke inhalation injury model device 200 includes a smoke chamber 210 , a pipe 220 , a hollow thermostat tube and an injury chamber 230 . Corresponding two ends of the pipe 220 are respectively connected with the smoke chamber 210 and the injury cha...

Embodiment 3

[0047] Example 3, see image 3 as shown,

[0048] The implementation principle and technical effect of the smoke inhalation injury model device 300 are the same as those in Embodiment 1. For a brief description, reference can be made to the corresponding content in Embodiment 1 for details not mentioned in this embodiment.

[0049] The smoke inhalation injury model device obtained through the above design can basically solve the problems of simulating the fire smoke inhalation scene, the design structure is simple and easy to operate, but in line with the purpose of further improving its function, the designer made the smoke inhalation injury model device Further improvements were made.

[0050] see image 3 , as shown in the figure, the smoke inhalation injury model device 300 includes a smoke chamber 310 , a pipe 320 , a hollow thermostat tube 321 and an injury chamber 330 . Corresponding two ends of the pipe 320 are respectively connected with the smoke chamber 310 and t...

Abstract

The invention relates to the medical experiment equipment technical field, and provides a smog inhalation injury model device which comprises a smog chamber, a pipeline, a hollow temperature adjustment pipe and an injury chamber. The smog chamber is provided with a smog outlet; the injury chamber is provided with a smog inlet; two opposite ends of the pipeline are respectively in connection with the smog outlet and the smog inlet, and allow the smog chamber to communicate with the injury chamber; the smog chamber is provided with a heating device; the injury chamber is provided with a taking port used for taking an experimental animal; the hollow temperature adjustment pipe is provided with an inlet and an outlet facilitating temperature adjustment agent entering and removal, and is winded on the pipeline. The smog inhalation injury model device can simulate a real fire smog inhalation scene, have a simple and reasonable structure, and effectively eliminate interference factors caused by thermal injuries.

Description

technical field [0001] The invention relates to the technical field of medical experimental equipment, in particular to a smoke inhalation injury model device. Background technique [0002] Inhalation injury is currently the most common cause of death in fire burn patients. Inhalation injury refers to the acute injury of the respiratory tract and lung parenchyma caused by inhalation of hot gas, steam, high-temperature dust, smoke, chemical toxic substances, etc. Among the inhalation injuries seen clinically, the main injury factor is smoke, which can cause acute Lung injury and acute respiratory distress syndrome. The condition is dangerous, the prognosis is poor, and it can further develop into multiple organ failure, with a case fatality rate of 30% to 40%. Smoke inhalation injury is still one of the important types of acute and critical diseases. Statistical results show that more than 85% of the deaths in fires are due to the influence of smoke, most of which are caus...
