Abstract

The utility model discloses a one-way valve for oxygen breathing tubes. The one-way valve comprises a valve body, an upper joint, a lower joint and a valve ball. The upper joint and the lower joint are respectively arranged on the upper portion and the lower portion of the valve body. Lumens of the upper joint and the lower joint are communicated with the inner cavity of the valve body. The valve ball is arranged in the inner cavity of the valve body. The one-way valve is characterized in that the valve ball is located on an opening edge of the lower joint in the inner cavity of the valve body. A crossed bracket is fixed in the middle of the inner cavity of the valve body. The one-way valve for the oxygen breathing tubes is featured with simple structure and convenience in use. The one-way valve for the oxygen breathing tubes can open and close oxygen inhalation paths in time according to breathing demands of patients so as to greatly increase the concentration of inhaled oxygen and reasonably save oxygen resources at the same time. The one-way valve is suitable for emergency centers, hospital wards, hyperbaric oxygen chambers, oxygen inhalation on plateaus, oxygen health care places and the like.

Description

Oxygen air tube check valve
Technical field
This utility model relates to the auxiliary device that oxygen uptake is used in a kind of medical treatment, specifically a kind of oxygen air tube check valve.
Background technology
At present, as needing high flow capacity, high concentration oxygen supply, often adopt mask oxygen-inspiration on the hospital clinical, no matter patient is that to exhale be to inhale, oxygen all continues large flow supply by the oxygen uptake pipeline, and waste of oxygen is larger, and can cause that oxygen concentration increases in the local space air, form potential safety hazard; Especially high altitude anoxia crowd no matter adopt mask oxygen-inspiration or nasal tube oxygen inhalation, is persistence oxygen supply mode, makes oxygen resource in the highlands preciousness cause waste and can not be fully utilized.
Summary of the invention
It is a kind of simple in structure, easy to use that the purpose of this utility model is to provide, can be according to patient's respiratory demand, and in good time open and close the oxygen uptake path, when significantly improving fraction of inspired oxygen, rationally save the oxygen air tube check valve of oxygen resource.
In order to reach above purpose, the technical scheme that this utility model adopts is: this oxygen air tube check valve, comprise valve body, top connection, lower contact and valve ball, be respectively equipped with top connection and lower contact in the upper and lower of valve body, the tube chamber of top connection and lower contact and the intracavity inter-connection of valve body, valve ball is located at the intracavity of valve body, it is characterized in that: valve ball is positioned at the opening's edge place of the endoceliac lower contact of valve, fixes " ten " font carriage at the endoceliac middle part of valve.
The beneficial effects of the utility model are: simple in structure, easy to use, can be according to patient's respiratory demand, open and close in good time the oxygen uptake path, when significantly improving fraction of inspired oxygen, rationally save the oxygen resource, be applicable to emergency center, hospital ward, hyperbaric oxygen chamber, plateau oxygen uptake and oxygen health care place etc.
Description of drawings
Fig. 1 is structure cross-sectional schematic of the present utility model;
Among the figure: 1, valve body; 2, top connection; 3, lower contact; 4, valve ball; 5, " ten " font carriage.
The specific embodiment
Make this utility model with reference to accompanying drawing 1.This oxygen air tube check valve, comprise valve body 1, top connection 2, lower contact 3 and valve ball 4, be respectively equipped with top connection 2 and lower contact 3 in the upper and lower of valve body 1, the intracavity inter-connection of the tube chamber of top connection 2 and lower contact 3 and valve body 1, valve ball 4 is located at the intracavity of valve body 1, it is characterized in that: valve ball 4 is positioned at the opening's edge place of the lower contact 3 of valve body 1 intracavity, fixes " ten " font carriage 5 at the middle part of valve body 1 intracavity.
When using this utility model, top connection 2 is fixed on the Oxygen tube of oxygen absorption mask, lower contact 3 is fixed on the oxygen supplying tube of oxygen cylinder or other oxygen source, when patients accepting oxygen inhalation, valve ball 4 leaves the interior opening's edge of lower contact 3, oxygen enters the inner chamber of valve body 1 in the tube chamber of lower contact 3, through hole by " ten " font carriage 5 peripheries enters the tube chamber of top connection 2 again, when patient exhales, valve ball 4 gets lodged on the interior opening's edge of lower contact 3, and oxygen no longer enters, and can make like this oxygen be interrupted supply, the oxygen resource of avoiding waste, and easy to use.This utility model also can adopt dual circuit to carry out oxygen supply and aerofluxus, such as with present hyperbaric oxygen chamber in used closed oxygen absorption mask support the use, at this moment, need to add a this utility model at oxygen supplying tube, simultaneously also to add a this utility model at exhaustor, only this utility model on exhaustor will oppositely be installed, oxygen passage open during patient inhales, waste discharge path blockade, oxygen path blockade during expiration, the waste discharge passage open, can be according to patient's respiratory demand, in good time open and close oxygen uptake and waste discharge path, when significantly improving fraction of inspired oxygen, rationally save the oxygen resource, and indoor oxygen concentration is controlled in the safety range better.
