Description

Bronchial asthma patient's expiratory gas flow self recording instrument

Technical field

This utility model relates to a kind of pulmonary disease medical apparatus and instruments, particularly a kind of bronchial asthma patient's expiratory gas flow self recording instrument.

Background technology

Bronchial asthma is a kind of commonly encountered diseases that produces health risk.This sick paresthesia epilepsy time often shows as paroxysmal, irregularities, randomness, when health check-up, often check to normally, like this, often can not in time diagnose, its order of severity can't be come guiding clinical treatment and medication with more correct and objective index, so that delay treatment, loses the therapy apparatus meeting, thereby it is cause more severe complications, even dead.So, airflow obstruction and variation thereof in time, objective determination is most important to patient diagnosis.Currently used expiratory gas flow analyzer complex structure need have the know-how personnel operation, and can not test at any time, and usage charges are higher.

Summary of the invention

The purpose of this utility model is to provide a kind of operation simple in structure, easy, patient can control application voluntarily, and bronchial asthma patient's expiratory gas flow self recording instrument of the expiratory gas flow of energy self-recording day part.

For reaching above purpose, the technical scheme that this utility model adopted is: this bronchial asthma patient expiratory gas flow self recording instrument, by breathing mask, the expiration conduit, collapsible pressure cell and recording clock body constitute, expiration conduit one end is connected the breathing mask downside, the other end connects goes up fixed disc, it is characterized in that collapsible pressure cell the downside of last fixed disc is fixedly connected, fixing flexible poke rod on the bottom panel of collapsible pressure cell, flexible poke rod contacts with the tail end of recording pen, the nib of recording pen contacts with the self-recording paper of recording clock surface, when the gas of breathing out enters in the collapsible pressure cell, collapsible pressure cell elongation, flexible poke rod on the bottom panel is stirred the tail end of recording pen downwards, the nib of recording pen is just drawn ascending curve on the self-recording paper of recording clock body, and the ascending amount of ascending curve is promptly represented the expiration amount.This utility model is also implemented by following measure: the fixedly pole of described recording clock body and fixed fold formula pressure cell all is fixed on the same bedplate, the recording clock body is cylindric, stir rotation (recording clock that available meteorological department uses replaces by winding up, so need not make separately), cover is loaded onto self-recording paper on the recording clock body, the ordinate of self-recording paper is represented the time of one day twenty four hours, the horizontal line of self-recording paper is the stroke of collapsible pressure cell, convert through experiment, can demarcate and be the expiration amount, establish vertical fixedly pole at the middle part of bedplate, recording pen is fixed on fixedly on the pole by bearing pin, on bedplate, also be provided with the pen retaining, can prevent that the nib of recording pen from leaving self-recording paper; Through hole is established at the middle part of fixed disc on collapsible pressure cell, and through hole is communicated with the expiration conduit, when exhaling in collapsible pressure cell, collapsible pressure cell elongation, when air-breathing, collapsible pressure cell resets under elastic reaction, thereby stirs the upper and lower line of recording pen, establish air-breathing air inlet pipe in the upper end of expiration conduit, establish unidirectional thin film in air-breathing air inlet pipe and the expiration conduit link, during expiration, the air-breathing air inlet pipe of the downward shutoff of unidirectional thin film, open when air-breathing, so that breathe extraneous fresh air; The band of also setting up departments in the both sides of breathing mask is so that fasten the head the patient; The segment length of described recording pen from bearing pin to nib is greater than one section from bearing pin to the recording pen tail end length, so that the scale of expiration amount amplifies; The pen shelves are fixed on the bedplate by turning cylinder, by the handle of stirring of stirring the pen shelves pen shelves are rotated.When using this utility model, face shield is worn over patient's snout, and fixes, bedplate can be horizontally fixed on the body at night and get final product, also can back on the body by day and carry with frenulum.

Advantage of the present utility model is: compare with the expiratory gas flow analyzer of present use, simple in structure, easy operation, can one day twenty four hours record at any time, all can read expiration amount any time from self-recording paper, and can analyze the interior expiration quantitative change situation of twenty four hours, can improve the diagnosis of bronchial asthma.

The specific embodiment

Make this utility model with reference to accompanying drawing 1.This bronchial asthma patient expiratory gas flow self recording instrument, by breathing mask 1, expiration conduit 2, collapsible pressure cell 3 and recording clock body 4 constitute, expiration conduit 2 one ends are connected breathing mask 1 downside, the other end connects goes up fixed disc 5, collapsible pressure cell 3 the downside of last fixed disc 5 is fixedly connected, fixing flexible poke rod 6 on the bottom panel of collapsible pressure cell 3, flexible poke rod 6 contacts with the tail end 11 of recording pen 7, the nib of recording pen 7 contacts with the self-recording paper 8 on recording clock body 4 surfaces, when the gas of breathing out enters in the collapsible pressure cell 3, collapsible pressure cell 3 elongations, flexible poke rod 6 on the bottom panel is stirred the tail end 11 of recording pen 7 downwards, and the nib of recording pen 7 is just drawn ascending curve on the self-recording paper 8 of recording clock body 4.The fixedly pole 10 of described recording clock body 4 and fixed fold formula pressure cell 3 all is fixed on the same bedplate 9, recording clock body 4 is cylindric, stir rotation by winding up, cover is loaded onto self-recording paper 8 on recording clock body 4, the ordinate of self-recording paper 8 is represented the time of one day twenty four hours, the horizontal line of self-recording paper 8 is the stroke of collapsible pressure cell 3, convert through experiment, can demarcate and be the expiration amount, establish vertical fixedly pole 10 at the middle part of bedplate 9, recording pen 7 is fixed on fixedly on the pole 10 by bearing pin, also is provided with pen retaining 12 on bedplate 9, can prevent that the nib of recording pen 7 from leaving self-recording paper 8; Through hole 13 is established at the middle part of fixed disc 5 on collapsible pressure cell 3, through hole 13 is communicated with expiration conduit 2, when in collapsible pressure cell 3, exhaling, and collapsible pressure cell 3 elongations, when air-breathing, collapsible pressure cell 3 resets under elastic reaction, thereby stirs recording pen 7 upper and lower line, establishes air-breathing air inlet pipe 16 in the upper end of expiration conduit 2, establish unidirectional thin film 14 in air-breathing air inlet pipe 16 and expiration conduit 2 links, during expiration, the air-breathing air inlet pipe 16 of unidirectional thin film 14 downward shutoff is opened when air-breathing; Also set up departments in the both sides of breathing mask 1 and to be with 15.
