Abstract
The invention relates to a disposable peak flow rate meter mouth, which is in a cylindrical shape formed by a blowing nozzle end and a connecting end with unequal circular areas. The circular area of the blowing nozzle end is half of the circular area of the connecting end; the outer edge of the connecting end is just inserted into a peak flow rate meter connecting frame. The design of reduction of the circular area of the blowing nozzle end is beneficial to a blowing nozzle held in the mouth, so that the comfort and the leakproofness of the blowing nozzle held in the mouth are increased; when a person blows from the blowing nozzle end of the blowing nozzle held in the mouth, air in the mouth is flown to the connecting end and is directly acted on a diaphragm in the peak flow rate meter; the inner part of the peak flow rate meter mouth still keeps in a circular structure, so that air can be flown in the mouth favorably, the fluid mechanics principle is met, the flowing direction is not changed, the largest liquidity of the air can be exerted, and the accuracy of the test result is increased.
Description
Technical field:
The present invention relates to a kind of technical field of medical instruments, be specifically related to a kind of peak flow meter mouth mouth.
Background technology:
Bronchial asthma is one of clinical modal disease, also be a kind of chronic lung disease, GINA (the Global Initiative for Asthma of new revision, GINA) point out that about there are 300,000,000 asthmatic patients in the current whole world, more than ten ten thousand people are about had to die from asthma, the life and health of the bronchial asthma serious threat mankind every year.It is reported that about there is Bronchial Asthmas 2,500 ten thousand people in China, also bring white elephant to society.Cough variant asthma is a kind of asthma of specific type, also be one of modal disease in chronic cough, make number one in China's chronic cough, the maximum expiratory flow rate (peak expiratory flow) understanding and grasping patient is in time one of objective evaluation conditions of patients important evidence.
Up to the present bronchial asthma remain a kind of disease that can not effect a radical cure, can the disease of prevention and corntrol but a kind of, and needs of patients long-term prescription under the guidance of doctor controls disease.Peak flow meter is the instrument of the easiest test patient pulmonary function, is also the instrument of clinical the most frequently used test patient maximum expiratory flow rate, and it is convenient to use, be easy to grasp.Past needs of patients oneself buys a set of peak flow meter to monitor the change of illness state of oneself, because the Economic Development Status of China is different, add the difference of patient to asthma disease cognitive assessment, advise that each patient buys a set of peak flow meter monitoring state of an illness also unrealistic, especially to see and treat patients every day many chronic coughs and asthmatic patient in Respiratory Medicine outpatient service, the pulmonary function situation understanding and grasping patient is timely and conveniently very important, the peak flow meter that existing market is sold mostly is the special product of special messenger, can not many people reuse for preventing cross infection.
Tradition peak flow meter mouth mouth is cylindric, two ends equal diameters, when sucking blowing nozzle end, needs to dehisce excessive, affect the comfortableness of patient, also easily cause gas leakage, had researcher that the blowing nozzle end of mouth mouth is designed to ellipse in recent years, although met state when human body is blown, but the shape of mouth mouth becomes the circle of link from the ellipse of blowing nozzle end, according to fluid mechanics principle, affect the flowing of gas in mouth mouth, may impact be had to test result.
One is needed to prevent cross infection clinically, the reusable peak flow meter of many people can be supplied again, disposable peak flow meter mouth mouth can solve peak flow meter cross infection and the reusable problem of many people, is applicable to the peak expiratory flow of Respiratory Medicine outpatient service monitoring chronic cough and asthmatic patient.
Summary of the invention:
The object of the invention is for overcoming above-mentioned shortcoming, designing a kind of disposable peak flow meter mouth mouth that can be external in peak flow meter link and more meet fluid mechanics principle.
Technical solution of the present invention is: disposable peak flow meter mouth mouth is the blowing nozzle end and the cylindrical shape that forms of link that are not waited by two terminal circle area, the blowing nozzle end area of a circle is 1/2 of the link area of a circle, link outer rim is just bumped in peak flow meter link, what the blowing nozzle end area of a circle reduced is designed with to be beneficial to and sucks blow gun, increase comfortableness and the seal of sucking blow gun, suck mouthful mouth blowing nozzle end blow time gas flow to link in mouth mouth, directly act on the diaphragm in peak flow meter, peak flow meter mouth mouth inside remains circular configuration, be conducive to the flowing of gas in mouth mouth, meet fluid mechanics principle, do not change flow direction, the mobility that gas is maximum can be played, increase the accuracy of test result.
Described disposable peak flow meter mouth mouth is made up of hard material, as: resin, plastics, PVC, polyethylene, lucite, cardboard.Mouthful mouth structure is once moulding completes, and is disposable product.
Tool of the present invention has the following advantages:
1. disposable peak flow meter mouth mouth is the blowing nozzle end and the cylindrical shape that forms of link that are not waited by two terminal circle area.
2. the blowing nozzle end area of a circle is 1/2 of the link area of a circle, and link outer rim is just bumped in peak flow meter link.What the blowing nozzle end area of a circle reduced is designed with to be beneficial to and sucks blow gun, increases comfortableness and the seal of sucking blow gun.
3. suck mouthful mouth blowing nozzle end blow time gas flow to link in mouth mouth, directly act on the diaphragm in peak flow meter, peak flow meter mouth mouth inside remains circular configuration, be conducive to the flowing of gas in mouth mouth, meet fluid mechanics principle, do not change flow direction, the mobility that gas is maximum can be played, increase the accuracy of test result.
4. a mouthful mouth is made up of hard material, as: resin, plastics, PVC, polyethylene, lucite, cardboard.
5. mouthful mouth structure is once moulding completes, and is disposable product.
Accompanying drawing illustrates:
Accompanying drawing 1 is the structural representation of the peak flow meter mouth mouth of invention detailed description of the invention.
Accompanying drawing 2 is peak flow meter and the peak flow meter mouth mouth syndeton schematic diagram of invention detailed description of the invention.
In figure, 1 mouthful of mouth, 2 blowing nozzle ends, 3 links, 4 peak flow meters, 5 links.
Detailed description of the invention:
As depicted in figs. 1 and 2: disposable peak flow meter mouth mouth 1 is the blowing nozzle end 2 and the cylindrical shape that forms of link 3 that are not waited by two terminal circle area.Blowing nozzle end 2 area of a circle is 1/2 of link 3 area of a circle, and link 3 outer rim is just bumped in the link 5 of peak flow meter 4.
Claims (2)
1. disposable peak flow meter mouth mouth, is characterized in that: the blowing nozzle end that described peak flow meter mouth mouth is not waited by two terminal circle area and the cylindrical shape that link is formed; The described blowing nozzle end area of a circle is 1/2 of the link area of a circle; Described link outer rim is just bumped in peak flow meter link.
