Abstract

An absorb-type breathing filter relates to a breathing filtering instrument. At present, cross infection exists in the patients who use respirators to assist ventilation because of general anesthesia operation in hospitals and various reasons and exists among patients in the same ward, the gas with pathogen breathed out by the patients is filled in the operating room, seriously threatens the health of medical staffs, and causes the other patients in the ward in the danger of iatrogenic infection. The utility model comprises a veil (1), the front part of the veil (1) is fixedly connected with a filtering core (2), and the veil (1) is also provided with an air inlet (3). The utility model overcomes the abuse that the current oxygen-absorbing veil is not provided with the filtering function of breathing air, and solves the problem that the patients feel uneasy while breathing as high-purity oxygen is breathed in and reducing of the air-outlet is needed in the existing veil, thus ensuring the patients feel smooth while breathing oxygen, in addition, the patients can also be supervised by the detecting port of carbon dioxide in the process of general anesthesia, which improves the rate of the successful operation.

Description

The absorption type breathing circuit filter

Technical field: the utility model relates to a kind of breath apparatus.

Background technology: at present, air pollution in the hospital is subjected to extensive attention day by day, general anesthesia operation and a variety of causes use the patient of lung ventilator assisted ventilation in hospital, and exist cross-infection between the patient with the ward, the shared cover of often several patients is breathed loop in the conventional in the past general anesthesia process, the patient expired gas that carries the germs of a disease is full of operating room, and medical personnel's health in serious threat, also makes simultaneously other patient in the ward be subjected to the danger of hospital-acquired infection.Different times the anesthesia patient needs the different modes oxygen uptake, before just having entered operating room general anesthesia administration, patient needs common oxygen uptake, patient's autonomous respiration disappears after the administration needs the pressurization mask oxygen inhalation, need the lung ventilator assisted respiartion after the intubate, by the lung ventilator oxygen supply, patient breathes in above overall process and does not pass through air filtration at present, be easy to be subjected to infection from bacterium in the equipment such as environment and lung ventilator, medical personnel also are subjected to patient's infection easily simultaneously, and patient need use different equipment to come assisted respiartion in difference anesthesia period, having a good chance of cross-infection, thus postoperative the patient of respiratory tract infection to occur a lot.

The utility model content: the purpose of this utility model is to provide a kind of absorption type breathing circuit filter that can filter input and output gas, and it comprises face shield 1, and the place ahead of described face shield 1 is connected with filter core 2, also is provided with air inlet 3 on face shield 1.The utility model is simple in structure; it can filter suction and breath easily; protected own and and other people healthy; the utility model is connected with air-intake filter 4; can be connected with oxygen cylinder simultaneously; can carry out the filtration of breath to the patient that autonomous respiration or no spontaneous breathing are arranged; after tested; filter efficiency reaches more than 99.9%; filter effect apparently higher than efficient mouth mask; it has overcome the drawback that present oxygen face mask does not have the breathing gas filtering function; what it had solved simultaneously that existing face shield exists will dwindle exhaust outlet when sucking high-purity oxygen, feels when making patient respiration the problem of feeling oppressed to make patient feel that in oxygen uptake breathing is unobstructed; in the general anesthesia process, can also utilize the detection mouth of carbon dioxide that patient is monitored in addition, improve the successful probability of operation.
