Abstract
The utility model discloses a movable breathing filter, which comprises an upper shell and a lower shell. An air inlet is formed in the upper shell. An air outlet is formed in the lower shell. The movable breathing filter is characterized in that the upper shell and the lower shell are connected through connecting pieces, and the upper shell and the lower shell are respectively and movably connected with the connecting pieces; and a sealed chamber is arranged between the upper shell and the lower shell, and a filtering device is arranged in the sealed chamber. The movable breathing filter not only can prevent pathogenic microorganisms exhaled by patients from polluting an instrument, but also can prevent the patients from inhaling the pathogenic microorganisms from the polluted instrument, the situation of cross infection is effectively prevented from occurring, the loss of the instrument is reduced and the lung function examination efficiency and the examination data accuracy are improved. Since the filtering device is made of an ultrathin polypropylene fiber filtering material, the efficiency is high, the resistance is low, and the movable breathing filter is simple and convenient to use and is economic and safe.
Description
Technical field
This utility model belongs to medical instruments field, specifically, relates to a kind of movable breathing circuit filter.
Background technology
Pulmonary function test is a kind of common tool of research physiology of respiration, also be the indispensable important rings of respiratory system disease diagnosis and treatment, during the routine pulmonary function test, patient's respiratory tract must be connected with the breath test pipeline of pulmonary function instrument, and require the patient in these complicated breathing circuits and equipment, to carry out the air-breathing and exhale action of best endeavors, in checking process, usually cause that the patient coughs, oral secretion when therefore the patient exerts oneself breathing or cough, food is residual to be looked into etc. very easily spirt and goes in inspection apparatus surface or the breathing circuit, but often be difficult to guarantee when using thoroughly cleaned in each patient's preoperation inspection instrument and loop and sterilize, very easily cause cross infection, there is poor filtration effect usually in existing breathing circuit filter simultaneously, be difficult to articulate interface shape and the face shape goodness of fit of docking with the patient oral cavity are poor, not only cause comfort poor, and patient's gas when exhale detecting very easily leaks from the interface edge of being difficult to articulate, and causes pulmonary function test to lose efficacy.
Summary of the invention
The technical problems to be solved in the utility model is to overcome above-mentioned defective, provides simple in structure, improves the comfortableness that the patient uses by the be difficult to articulate shape of interface of change, and further guarantees the movable breathing circuit filter of pulmonary function test accuracy.
For addressing the above problem, the technical scheme that this utility model adopts is:
A kind of movable breathing circuit filter, comprise upper shell and lower house, upper shell is provided with air inlet, and lower house is provided with the gas outlet, it is characterized in that: connect by connector between described upper shell and the lower house, and upper shell and lower house flexibly connect respectively at connector; Be provided with annular seal space between described upper shell and the lower house, be provided with defecator in the annular seal space.
As a kind of improvement, described connector in the form of a ring, its medial surface flexibly connects with upper shell and lower house respectively.
As a kind of improvement, described connector medial surface is threaded with upper shell and lower house respectively.
As a kind of improvement, described defecator is the superfine polypropylene fiber membrane of static electrification, and its thickness is 0.1-0.5mm.
As a kind of improvement, described upper shell and lower house are the disc of symmetrical distribution, and the same top that is located in upper shell of air inlet, and the gas outlet is with the bottom that is located in lower house.
Owing to adopted technique scheme, compared with prior art, connect by connector between this utility model upper shell and the lower house, and upper shell and lower house flexibly connect respectively at connector; Be provided with annular seal space between described upper shell and the lower house, be provided with defecator in the annular seal space.When patient's breath is through closed chamber during use, pathogen such as the antibacterial in the gas, virus are attracted on the defecator, both can prevent the microbiological contamination instrument that the patient breathes out, can prevent that again the patient from sucking pathogenic microorganism from the instrument that pollutes, avoid the generation of cross infection effectively, reduce the loss to instrument simultaneously, improve the accuracy of lung function work efficiency and detection data.Defecator is the superfine polypropylene fiber filter material, efficient low-resistance, easy to use, economic security.
The utility model is described in further detail below in conjunction with the drawings and specific embodiments simultaneously.
Description of drawings
Fig. 1 is the structural representation of a kind of embodiment of this utility model.
Among the figure: the 1-air inlet; The 2-upper shell; The 3-connector; The 4-defecator; The 5-lower house; The 6-gas outlet.
The specific embodiment
Embodiment:
As shown in Figure 1, a kind of movable breathing circuit filter comprises upper shell 2 and lower house 5, and upper shell 2 is provided with air inlet 1, and lower house 5 is provided with gas outlet 6.Connect by connector 3 between described upper shell 2 and the lower house 5, and upper shell 2 and lower house 5 flexibly connect respectively at connector 3.Be provided with annular seal space between described upper shell and the lower house, be provided with defecator 4 in the annular seal space.
In the present embodiment, described connector 3 in the form of a ring, its medial surface flexibly connects with upper shell 2 and lower house 5 respectively.The mode that flexibly connects has many kinds, and what wherein adopt in the present embodiment is that the connector medial surface is threaded with upper shell and lower house respectively.
In the present embodiment, described defecator is the superfine polypropylene fiber membrane of static electrification, and its thickness is 0.1-0.5mm.In addition, described upper shell 2 and lower house 5 are the disc of symmetrical distribution, and the same top that is located in upper shell of air inlet, and the gas outlet is with the bottom that is located in lower house.
When patient's breath is through closed chamber during use, pathogen such as the antibacterial in the gas, virus are attracted on the defecator, both can prevent the microbiological contamination instrument that the patient breathes out, can prevent that again the patient from sucking pathogenic microorganism from the instrument that pollutes, avoid the generation of cross infection effectively, reduce the loss to instrument simultaneously, improve the accuracy of lung function work efficiency and detection data.Defecator is the superfine polypropylene fiber filter material, efficient low-resistance, easy to use, economic security.
This utility model is not limited to above-mentioned preferred forms, and anyone should learn the structural change of making under enlightenment of the present utility model, every with the utlity model has identical or akin technical scheme, all belong to protection domain of the present utility model.
