Abstract
The utility model discloses a lung function test bacterial filter which comprises an upper shell and a lower shell, wherein a filter layer is arranged between the upper shell and the lower shell, an instrument connector is arranged at the lower end of the lower shell, the upper shell is provided with an oval biting opening, and a protection wing is arranged on the periphery of the oval biting opening. The lung function test bacterial filter is simple in structure, and convenient to use, and prevents air leakage at corners of a mouth.
Description
Technical field
This utility model relates to a kind of medical apparatus and instruments.
Background technology
Pulmonary function test is that necessity of respiratory system disease one of checks, for detecting lung in early days, the air flue pathological changes, the degree that is in a bad way of assess disease, the curative effect of evaluation medicine or other Therapeutic Method, differentiate dyspneic reason, the diagnosis diseased region, the assessment pulmonary function has important directive significance to the tolerance of operation or labor intensity tolerance and to critical patient's aspects such as monitoring, when clinical examination, need patient's blow gun to blow, the blow gun of traditional structure is because its reasons in structure, can't satisfy the demand, particularly the apoplexy sequela patient tends to corners of the mouth gas leakage when using blow gun, can't accurately measure, and the blow gun of employing traditional structure, the residual of saliva sputum very easily taken place, increased the chance of various cross infections virtually.
Summary of the invention
The purpose of this utility model provides a kind of simple in structure, and is easy to use, stops the lung function biofilter of various cross infection chances in the gas leakage of the prevention corners of the mouth.
To achieve these goals, the technical solution adopted in the utility model is: a kind of lung function biofilter, comprise upper casing and lower casing, between described upper casing and the lower casing filter course is installed, the lower end of lower casing has tool interface system, described upper casing has ellipse is difficult to articulate, and oval periphery of being difficult to articulate also is equipped with flap.
After adopting said structure, the utlity model has and be difficult to articulate, the patient can must blow after the interlock easilier, oval periphery of being difficult to articulate also is equipped with flap simultaneously, can be coated on gingival edge, even the apoplexy sequela patient can not cause corners of the mouth gas leakage, between upper casing and the lower casing filtering layer is installed simultaneously yet, can prevent that the saliva sputum is dropped in epivalve, prevents the chance of cross infection.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing, this utility model is further described specifically.
As shown in Figure 1, a kind of lung function biofilter comprises upper casing 1 and lower casing 2, between described upper casing 1 and the lower casing 2 filter course 3 is installed, the lower end of lower casing 1 has tool interface system 4, and described upper casing 1 has ellipse and is difficult to articulate 5, and oval 5 the periphery of being difficult to articulate also is equipped with flap 6.
This utility model is separated by patient respiration road and pulmonary function instrument pipeline, intercepts effectively that the spittle, surplus expectorant, food are residual, pathogen etc., not only prevents from polluting the pulmonary function instrument, effectively avoids the generation of cross infection again.
Claims (1)
1. lung function biofilter, comprise upper casing (1) and lower casing (2), between described upper casing (1) and the lower casing (2) filter course (3) is installed, the lower end of lower casing (1) has tool interface system (4), it is characterized in that: described upper casing (1) has ellipse is difficult to articulate (5), and the be difficult to articulate periphery of (5) of ellipse also is equipped with flap (6).
