Description

Technical Field

[0001] The utility model belongs to the technical field of poisoning boxes, and in particular relates to a poisoning box capable of measuring gas concentration. Background Art

[0002] Most of the existing poisoning boxes are made of acrylic materials with good sealing properties, and the side walls of the box are provided with air inlets and outlets. Using inhalation poisoning devices to make respiratory inhalation poisoning animal models is an important means to study the occurrence and development of related diseases. The application of poisoning boxes better restores the common inhalation gas poisoning in the clinic, is closer to the characteristics of clinical cases, and is convenient for studying the pathogenesis of diseases. However, it is currently difficult to monitor and control the gas concentration in the poisoning box in real time, which greatly reduces the success rate of constructing respiratory inhalation poisoning animal models. For example: related studies have shown that when making an animal model of delayed encephalopathy caused by carbon monoxide poisoning, it is necessary to meet the conditions of introducing 1000ppm of carbon monoxide gas into the poisoning box and maintaining it for 30 minutes, and then introducing 3000ppm of carbon monoxide gas again and maintaining it for 10 minutes. At this time, the success rate of making animal models of delayed encephalopathy caused by carbon monoxide poisoning is relatively high, but traditional poisoning boxes are difficult to meet this requirement, and the current poisoning box, because the gas is directly introduced through a pipeline, makes the gas enter the cabinet and is unevenly distributed, which affects the experimental safety and experimental effect. Utility Model Content

The device is also provided with a gas detector, which cooperates with the function of promoting the uniform distribution of gas when entering the cabinet, can effectively and quickly detect the gas concentration in the cabinet, and monitor the gas concentration in the cabinet in real time. The monitoring data is displayed in real time on the touch display device, which helps to confirm the gas intake and control the gas intake, thereby improving the construction quality of the animal experimental model.

[0004] To achieve the above objectives, the utility model provides the following technical solutions: a contamination box capable of measuring gas concentration, comprising a cabinet, the cabinet comprising a base, a frame is installed on the top of the base, an acrylic plate is installed on the inner side of the frame, a sealed door is hingedly installed on the front side of the frame, a first mounting hole is penetrated on the acrylic plate on the top of the frame, a second mounting hole is penetrated on the acrylic plate on the side of the frame, an air inlet joint is clamped on the inner side of the first mounting hole, an exhaust joint is clamped on the inner side of the second mounting hole, and the air inlet joint is clamped on the inner side of the second mounting hole.

The accuracy of the experimental results is improved, and the problem of local high-concentration accumulation of gas inside is avoided, thereby improving the safety of the experiment. At the same time, the device is also equipped with a gas detector, which cooperates with the function of promoting uniform distribution of gas when entering the cabinet, and can effectively and quickly detect the gas concentration in the cabinet, and monitor the gas concentration in the cabinet in real time.
