Abstract

The utility model relates to a breathing filtering device used for testing lung functions and particularly relates to a breathing filtering device used for testing lung functions which can avoid cross infection, belonging to the technical field of medical equipment. The breathing filtering device used for testing lung functions comprises an upper shell and a lower shell, wherein a filtering membrane is arranged between the upper shell and the lower shell, an upper port of the upper shell is connected with a mouthpiece, a lower port of the lower shell is connected with a sensor interface of a lung function testing instrument, and the filtering membrane is a microporous breathable membrane made of activated carbon fiber. The filtering membrane of the breathing filtering device used for testing lung functions is the microporous breathable membrane made of the activated carbon fiber, and as the activated carbon fiber is an efficient adsorption material, saliva, droplets, residual sputum, food debris, pathogenic bacteria and the like in gas exhaled by a person to be tested can be effectively adsorbed so as to prevent a tube of the lung function testing instrument from being polluted and effectively prevent the occurrence of the cross infection.

Description

Pulmonary function detection breath device
Technical field
The utility model relates to the breath device that pulmonary function detection is used, and particularly relates to a kind of pulmonary function detection breath device of avoiding cross-infection, belongs to the medical devices technical field.
Background technology
Pulmonary function detection is a kind of common method of research physiology of respiration, also is the indispensable important rings of respiratory disease diagnosis and treatment.At present, pulmonary function detection has been widely used in every field such as Respiratory Medicine, chest abdominal surgery, paediatrics, gynemetrics, occupational disease evaluation, plateau medicine, health examination, pulmonary function detection is used so extensively and is important, but exists the possibility of cross-infection during conventional pulmonary function detection.
During the routine pulmonary function detection, testee's respiratory tract must be connected with the testing conduit of pulmonary function detection instrument, and require the testee in these pipeline loops, to carry out the air-breathing and air blowing of peak power of repetition, in the testing process, usually cause that the testee coughs, at this moment, the saliva that the testee firmly breathes or cough causes, the spittle, surplus phlegm, swill etc. must spray, adhere to and be deposited in the detector pipeline loop, pollute, these pipelines can not clean completely when each testee uses, sterilize, and very easily cause cross-infection.Therefore, people begin to use filter between testee and pulmonary function detection instrument, filter the bacterium of adsorbing in testee's breath by filter, not only reduce the cross-infection odds, improve the pulmonary function detection quality, reduce simultaneously the number of times of unpicking and washing of detector again, prolong detector service life.But there is the problem of poor filtration effect in existing filter, fully the saliva in the adsorption filtration testee breath, the spittle, surplus phlegm, swill, pathogen etc.
The utility model content
The purpose of this utility model is in order to overcome prior art existing problems and defective, a kind of pulmonary function detection breath device of avoiding cross-infection to be provided.
The technical solution of the utility model is: a kind of pulmonary function detection breath device, comprise upper shell and lower house, between upper and lower casing, be provided with filter membrane, described upper shell upper port connects is difficult to articulate, the lower house lower port connects pulmonary function detection Instrument sensor interface, and described filter membrane is the microporous breathable film made from NACF.
Described upper shell and lower house are fastened and connected or are threaded.
The beneficial effects of the utility model are:
1, the utility model pulmonary function detection is the microporous breathable film made from NACF with the filter membrane of breath device, because NACF is a kind of efficient sorbing material, can effectively adsorb pathogens such as saliva, the spittle, surplus phlegm, swill and staphylococcus aureus in testee's breath, Pseudomonas aeruginosa, prevent the pollution of pulmonary function detection instrument pipeline, effectively prevent the generation of cross-infection;
2, the utility model is simple in structure, and use, easily manufactured is easy to promotion and implementation.
Description of drawings
Fig. 1 is the structural representation of the utility model pulmonary function detection with the breath device.
Number in the figure: 1 is upper shell, and 2 is filter membrane, and 3 is lower house.
The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is described in further detail:
Embodiment 1: referring to Fig. 1, a kind of pulmonary function detection breath device, comprise upper shell 1 and lower house 3, described upper shell 1 upper port connects is difficult to articulate, lower house 3 lower port connect pulmonary function detection Instrument sensor interface, be provided with filter membrane 2 between upper and lower casing, described filter membrane 2 is microporous breathable films made from NACF.
Described upper shell 1 and lower house 3 are fastened and connected.
Embodiment 2: figure does not draw, and embodiment 2 is substantially the same manner as Example 1, and something in common does not repeat, and difference is: described upper shell 1 and lower house 3 are threaded.
