Abstract

The utility model relates to a novel air-leakage prevention mouthpiece for detecting the lung function. Air bags or silica gel bags which are matched with the mouth shape are combined on the common mouthpiece and are respectively positioned in the mouth and outside the mouth of a user; the novel air-leakage prevention mouthpiece is closely attached to two sides of the oral cavity of a user in the using process by utilizing the plasticity of the air bags or silica gel bags so as to achieve the effect of effectively preventing air leakage. The novel air-leakage prevention mouthpiece can be used on all traditional lung function instruments without special treatment, is strong in practicability and generality and has favorable application value and prospect.

Description

Novel lung function is difficult to articulate with anti-gas-leak

Technical field

This utility model patent relates to a kind of novel lung function and is difficult to articulate with anti-gas-leak.In lung function, especially the relatively poor patient of conformability prevents to leak gas in testing process and has original advantage.

Background technology

Pulmonary function test is one of common and necessary inspection means of respiratory system disease; For detecting lung, air flue pathological changes in early days; The degree that is in a bad way and the prognosis of assess disease, the assessment pulmonary function all has the important clinical meaning to tolerance or the labor intensity tolerance of operation and to critical patient's aspects such as monitoring.The principle of pulmonary function test mainly is that relevant parameter such as the flow velocity, capacity to air-flow detects, if " gas leakage " in checking process, occurs, and will be to the reliability generation significant effects of check result.At present, use in the lung function process be difficult to articulate or the disposable main patient of dependence lips of being difficult to articulate pack tightly and prevent gas leakage, this method is poor at patient's conformability, perhaps under the unable situation of interlock, situation about usually leaking air.

In order to solve " gas leakage " this situation in the lung function process, we have designed a kind of novel lung function and have been difficult to articulate with anti-gas-leak, and this is difficult to articulate simple for production, and all at present lung function devices all can use, and have good versatility and practical value.

The utility model content

The technical scheme that this utility model adopts is: at present general being difficult to articulate, install 2 annular air-pockets (or silicon capsule) additional, in laying respectively at mouthful with lip outside, utilize the plasticity of air bag (or silicon capsule) to be close to the inside and outside both sides of lip; Reach and prevent the effect of leaking gas.Simultaneously, air bag itself also has the effect that barrier air exposes.This scheme is easy, only on the existing basis of being difficult to articulate, installs annular air-pocket (or silicon capsule) additional, can reach effectively to prevent the effect of leaking gas.Practicality and versatility are very good, have good using value and prospect.

Description of drawings

Further specify below in conjunction with accompanying drawing this utility model:

Fig. 1 is the structural representation of this utility model.Common being difficult to articulate that the 1 cooperation pulmonary function appearance made for nontoxic medical plastic material uses, the air bag or the silicon capsule of the 2 cooperation shape of the mouth as one speaks of being made by non-toxic plastic are incorporated on common being difficult to articulate.The air bag of the pulmonary function appearance direction of plugging into is slightly larger than the air bag of patient's interlock direction, and the latter can be contained in patient's mouth.Fig. 2 for this novel lung function with the anti-gas-leak pulmonary function appearance end vertical view of plugging into of being difficult to articulate; Fig. 3 is difficult to articulate with anti-gas-leak for this novel lung function and sucks the end vertical view.

Practical implementation

During use; Novel lung function is difficult to articulate with anti-gas-leak to be connected on the pulmonary function appearance, and user is positioned over lip between two air bags or the silicon capsule, because air bag or silicon capsule have plasticity; Fit tightly both sides, oral cavity in the use, reach and prevent the effect of leaking gas at user.

Claims

1. a novel lung function is difficult to articulate with anti-gas-leak, it is characterized in that: the air bag or the silicon capsule of the cooperation shape of the mouth as one speaks that non-toxic plastic is made are incorporated on common being difficult to articulate.

2. novel lung function according to claim 1 is difficult to articulate with anti-gas-leak, it is characterized in that: by the anti-gas-leak structure that constitutes with mouthful outer 2 air bags or silicon capsule in the mouth.
