[0002] Medical waste refers to the waste generated during the process of diagnosis, treatment, nursing and other activities for patients. Medical waste may contain a large number of pathogenic microorganisms and harmful chemicals, and even radioactive and damaging substances. Therefore, medical waste is an important risk factor causing disease transmission or related public health problems. In addition, during the stacking process of medical waste, certain organic substances decompose under the influence of temperature and moisture, producing harmful gases, so medical waste needs to be disposed of.

[0003] The gas sampling in the prior art requires that the air inside the device be emptied first and then the waste gas be injected. In the process of exhausting the gas, the number of samples is often affected by conditions such as the density of the gas, which has a certain impact on the collection efficiency of the waste gas required for detection. For this reason, we propose a gas sampling device for medical waste disposal environments. Utility Model Content

DETAILED DESCRIPTION

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] The air transfer structure 4 includes a flange 401, the left side of the containment cabin 3 is fixedly connected with the flange 401, the top of the flange 401 is fixedly connected with an air transfer cavity 402, the interior of the air transfer cavity 402 is fixedly provided with an anti-corrosion coating 403, the top of the air transfer cavity 402 is fixedly connected with a connecting needle 404, the top of the air transfer cavity 402 is movably connected with a dustproof seat 405, and the bottom of the dustproof seat 405 is fixedly connected with a heat preservation cover 406.

[0022] In specific implementation, the gas analyzer 12 adopts a PULSAR non-dispersive infrared gas analyzer. The non-dispersive infrared technology is a spectral gas detection method based on gas absorption theory. The infrared radiation emitted by an infrared light source is absorbed by a certain concentration of the gas to be tested. The light intensity at a specific wavelength will change corresponding to the gas concentration. Therefore, the gas concentration can be calculated based on the change in light intensity.

[0023] The sampling pump 8 is based on the circular motion output by the motor 9 (the output of the motor 9 causes the diaphragm inside the pump to perform reciprocating motion). This motion causes the volume in the pump chamber to be compressed or stretched, forming a vacuum (negative pressure), and generating a pressure difference between the pump's suction port and the external atmospheric pressure. Under the action of this pressure difference, the gas or liquid is pressed (sucked) into the pump chamber, and then discharged into the analysis cabin 11 through the exhaust port and exhaust pipe 10 to prepare for the next step of analyzing the gas concentration.

[0024] When implementing, follow these steps:

[0025] 1) First hang the arc handle 2 in the gas ring mirror that needs to be sampled and tested;

[0026] 2) Then the sampling pump 8 is started. At this time, the sampling pump 8 generates a pressure difference between the pump suction port and the external atmospheric pressure based on the circular motion output by the motor 9. Under the action of this pressure difference, the gas to be sampled is pressed (sucked) into the pump cavity through the gas transfer cavity 402 and the gas storage pipe 5, and then discharged into the analysis cabin 11 through the exhaust port and the exhaust pipe 10;

[0027] 3) The gas analyzer 12 emits infrared radiation through its internal infrared emitting device. After being absorbed by a certain concentration of the gas to be measured, the light intensity at a specific wavelength will change corresponding to the gas concentration. Therefore, the gas concentration can be calculated based on the change in light intensity.

[0028] 4) Finally, the gas analyzer 12 is electrically connected to the display inside the display cabin 1 to transmit the detected gas concentration data to the display, and the user can now know the waste gas sampling results inside the gas environment.

[0029] In summary, the gas sampling device for medical waste disposal environments, by setting up the gas transmission structure 4 and cooperating with the setting of the sampling pump 8, realizes that the gas transmission cavity 402 can absorb gas from multiple directions, which not only avoids the exposure of the gas storage pipe 5, the sampling pump 8, and the motor 9, making the interior of the cabin more beautiful, but also solves the problem that the existing gas sampling device cannot absorb gas from multiple directions at the same time, thereby affecting the working efficiency of the gas sampling device.

[0030] Furthermore, by providing the analysis cabin 11 and the gas analyzer 12, in coordination with the setting of the filling layer 7, it is achieved that after the sampling pump 8 completes the extraction and compression of the gas, the sampled gas inside the gas storage pipe 5 can be directly preheated and insulated, and the sampled gas can be directly passed into the analysis cabin 11, and the gas analyzer 12 can detect the gas without the need for a preheating treatment, thereby increasing the response speed of the gas detection.
