System and method for detecting use degree of filter element of operation smoke exhauster

Abstract

The invention discloses a system and method for detecting the use degree of a filter element of an operation smoke exhauster, the system for detecting the use degree of the filter element of the operation smoke exhauster comprises a flow detection unit (1), a smoke sensor (2) and a main control unit (3), the filter element (4) is arranged in a smoke exhaust channel, and the flow detection unit and the smoke sensor are both arranged in the smoke exhaust channel. The flow detection unit is electrically connected with the smoke sensor and used for detecting the gas flow at the filter element and the smoke amount in the gas, the main control unit is electrically connected with the flow detection unit and the smoke sensor, the main control unit comprises a storage unit (31) and a timer (32), and the timer is used for measuring the use time of the filter element in each gas flow and smoke amount state; the storage unit is used for storing the use time of the filter element in each gas flow and smoke amount state, and the main control unit can judge the use degree of the filter element according to information in the storage unit. According to the operation smoke extractor filter element use degree detection system, detection of the filter element use degree is more accurate.

Description

technical field [0001] The invention relates to the field of equipment detection, in particular to a detection system for the use degree of a filter element of a surgical smoke evacuator, and also to a method for detecting the use degree of a filter element of a surgical smoke evacuator. Background technique [0002] Laparoscopic surgery is highly instrument-dependent. The application of energy instruments such as monopolar and bipolar energy instruments is indispensable in surgical cutting and hemostasis. [0003] At present, most energy devices use thermal energy or high-speed low-frequency oscillating mechanical energy to cause protein denaturation. During this process, a large amount of smoke will be generated, and the smoke contains harmful substances such as acetylene and organic benzene, so the smoke needs to be filtered before it can be discharged. , so the filter element is needed, and the service life of the filter element is limited, so it is necessary to detect t...

Problems solved by technology

[0003] At present, most energy devices use thermal energy or high-speed low-frequency oscillating mechanical energy to cause protein denaturation. During this process, a large amount of smoke will be generated, and the smoke contains harmful substances such as acetylene and organic benzene, so the smoke needs to be filtered before it can be discharged. , so the filter element is needed, and the service life of the filter element is limited, so it is necessary to detect the degree of use of the filter element so that it can be replaced in time

[0004] In the prior art, the judgment of the use degree of the filter element is generally carried out by recording the service time of the filter element and the air pressure at the outlet end of the filter element to the exhaust channel. The difference in air pressure is very small, and it is very easy for the filter element to be scrapped before it reaches its service life, resulting in waste of resources; or it is not scrapped after reaching its service life, so that the toxic substances in the smoke are not filtered out, causing environmental pollution.
