Abstract
The utility model relates to the field of medical equipment, in particular to a lung function detection breathing filter structure, which comprises a body, wherein the body is of a tubular structure, and a filtering membrane accommodating cavity extending outwards is arranged in the middle of the body; the anti-reflux valve is pressed to be opened when the administration end is inserted into the mouthpiece for administration, and the anti-reflux valve is pressed to be closed when the patient end blows air. After the scheme is adopted, the condition of cross infection can be prevented when the medicine is used.
Description
Technical Field
The utility model relates to the field of medical equipment, refer in particular to a lung function detects respiratory filter structure.
Background
A pulmonary function tester is a medical device used to measure the volume of air inhaled and exhaled by the lungs. The lung function test can be carried out and the lung health condition can be tracked, and common lung function detection parameters including FVC, FEV1/FVC and the like can be measured.
The lung function detector is mainly used for definite diagnosis of diseases such as asthma, chronic Obstructive Pulmonary Disease (COPD) and the like and judging the severity of the diseases, can also be used for differential diagnosis of dyspnea, and can evaluate the effects of medicines and treatment and guide patients to adjust treatment schemes. The portable lung function detector is mainly used for screening and follow-up diagnosis of community COPD patients, and can be used for deriving examination records and graphs for long-term monitoring and implementing health management.
The lung function detector needs to be connected with a breathing filter to filter pollutants such as droplets, sputum and pathogenic bacteria blown by a patient, the mouthpiece of the existing breathing filter in the existing market is usually only provided with the mouthpiece of the patient end during detection, but the condition that the patient needs to take medicine (salbutamol sulfate) firstly during most of the current lung function detection is ignored, and cross infection occurs during mixed use of medicines.
Therefore, the present inventors have further studied and developed a lung function detecting respiratory filter structure, which is thus developed.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a pulmonary function detects respiratory filter structure prevents to appear cross infection's the condition when using medicine.
In order to achieve the above purpose, the technical solution of the present invention is as follows:
a lung function detecting respiration filter structure comprises
The filtering membrane accommodating device comprises a body, a filter membrane accommodating cavity and a filter membrane fixing part, wherein the body is of a tubular structure, and the middle part of the body is provided with a filtering membrane accommodating cavity extending outwards;
the anti-reflux valve is pressed to be opened when the administration end is inserted into the mouthpiece for administration, and the anti-reflux valve is pressed to be closed when the patient end blows air.
Furthermore, the anti-reflux valve is of a duckbill structure, and the opening of the duckbill structure faces to the connecting end of the mouthpiece.
Furthermore, the anti-reflux valve is of a film type structure, one end of the film is attached to the side wall of the connecting end of the mouthpiece, and the other end of the film is attached to the inside of the mouthpiece.
After the scheme is adopted, compared with the prior art, the utility model, have following advantage:
can be applicable to multiple inspection instrument and ware of dosing, make things convenient for patient to detect after dosing, can correspond different situation free choice, the cross infection's the condition appears when preventing to use medicine.

Detailed Description
The invention will be further described with reference to the accompanying drawings and specific embodiments.
As shown in the figure, the lung function detection breathing filter structure comprises a filter body 1 and a mouthpiece 2, wherein the body 1 is of a tubular structure, a filtering membrane accommodating cavity 11 which extends outwards is formed in the middle of the body 1, and the accommodating cavity 11 is of a circular sheet structure; a filtering membrane is arranged in the accommodating cavity 11 and is used for adsorbing bacteria in the exhaled air of the tested person.
The connecting end of the mouthpiece 2 is sleeved on the body 1, the opening end of the mouthpiece 2 is provided with an anti-reflux valve, when the drug delivery end is inserted into the mouthpiece 2 for drug delivery, the anti-reflux valve is pressed to be opened, and the patient end is pressed to be closed when blowing.
The first embodiment is as follows: when the anti-reflux valve is a duckbill valve 21, the opening of the duckbill shape faces the connecting end of the mouthpiece 2, when the medicine feeder 3 is inserted into the connecting end, the duckbill valve 21 is pressed to be opened, and is naturally closed when being pulled out.
Example two: when the anti-reflux valve is a membrane 22 valve, the drug administration end rushes open the membrane 22 through the impact of the drug liquid, and the patient end is pressed and closed when being blown, and is normally and naturally closed.
The aforesaid is only the embodiment of the utility model discloses, all simultaneously the utility model discloses in related words such as "upper and lower, left and right, centre" only do the reference usefulness, not absolutely restricted, all utilize the utility model discloses carry out insubstantial change, all shall belong to the act of infringing the protection scope of the utility model.
