Recovery and treatment system for exhaled air of critical patient in hospitals

Abstract

The invention discloses a recovery and treatment system for exhaled air of a critical patient in a hospital. The recovery and treatment system comprises a monitoring system, a data acquisition systemand a waste gas treatment device, wherein the data acquisition system performs data acquisition for the pressure, flow rate, flow velocity and ambient pressure of gas on the waste gas treatment device; the monitoring system is electrically connected with the data acquisition system and controls and adjusts the waste gas treatment device; the waste gas treatment device comprises a gas storage tank,a vacuum pump, a steam-water separator and filtering equipment which are in sequential communication; the gas storage tank is connected with breathing equipment of each department through a gas storage pipeline; a one-way valve is arranged on each gas storage pipeline; and a safety relief valve is also arranged on each gas storage pipeline. The recovery and treatment system provided by the invention has the advantages of multi-stage filtration, real-time monitoring and timely processing.

Description

technical field [0001] The invention relates to the field of waste gas treatment, in particular to a recovery and treatment system for the exhaled gas of critically ill patients in a hospital. Background technique [0002] Respiratory equipment can help patients with dyspnea to assist breathing. It is widely used in the current medical care process. Generally, the exhaust gas produced by respiratory equipment is not infectious, but when the patient has certain infectious diseases, its exhaled If the gas is discharged directly into the atmosphere, it will cause infection. If it is highly infectious, the consequences will be disastrous. [0003] At present, in the process of treating the exhaust gas generated by patients through respiratory equipment, most of them have not been effectively treated, and are only realized by adding filters. This method can treat the exhaust gas to a certain extent and avoid large-scale infection, but In the actual use process, it is impossible ...

[0002] Respiratory equipment can help patients with dyspnea to assist breathing. It is widely used in the current medical care process. Generally, the exhaust gas produced by respiratory equipment is not infectious, but when the patient has certain infectious diseases, its exhaled If the gas is discharged directly into the atmosphere, it will cause infection. If it is highly infectious, the consequences will be disastrous

[0003] At present, in the process of treating the exhaust gas generated by patients through respiratory equipment, most of them have not been effectively treated, and are only realized by adding filters. This method can treat the exhaust gas to a certain extent and avoid large-scale infection, but In the actual use process, it is impossible to achieve large-scale processing. Existing, small-batch, single-equipment processing forms are inefficient and prone to failure at the patient level, resulting in difficulty in exhaling, which is not conducive to treatment and is likely to cause accidents. It is difficult to check in time, so after a fault occurs, the exhaust gas will be directly discharged into the atmosphere, and it will not be able to deal with it
