Abstract
The utility model relates to an oxygen conveying pipeline with functions of safe guarding and prompt, which is composed of a subjective pipeline and a safety valve device which is combined with the subjective pipeline. One end of the subjective pipeline is connected with an air supply and used as an air supply end, and the other end is provided with structures of a rhinobyon or a mask to contact with human bodies and used as a use end. The safety valve device is arranged near the air supply end and is composed of a valve body and an elastic packing body to be connected with the subjective pipeline directly or through an assisted piece. The oxygen conveying pipeline with functions of safe guarding and prompt causes an ordinary oxygen conveying pipeline to have functions of safe guarding and prompt at the time of blocking or obturation and powerfully guarantees the oxygen therapy to go with a swing.
Description
Technical field
This utility model relates to a kind of oxygen delivery pipeline that security protection and prompt facility are arranged, and belongs to the medical apparatus and instruments manufacture technology field.
Background technology
Existing all medical terminal oxygen delivery pipelines, be commonly referred to as disposable use Oxygen tube or face shield, about 2 meters of entire length, be PVC (polrvinyl chloride) or silica gel hose, even easily caused air-flow to reduce total blockage in the use by crimping, and whole pipeline does not have any safety instruction function, and patient and medical personnel are difficult in time discover, appreciable impact oxygen therapy effect.Some related application in recent years (200620082474.6,200720017255.4 etc.) all on this problem, do not broken through.
Summary of the invention
The purpose of this utility model is a kind of oxygen delivery pipeline that security protection and prompt facility are arranged of design, pipeline is caused remarkable obstruction by crimping or upspring automatically decompression and send alarm sound of relief valve when inaccessible in the use, the prompting medical personnel check pipeline, in time eliminate obstruction or inaccessible factor assurance oxygen therapy and carry out smoothly.
Realize that scheme of the present utility model is: this utility model is made up of main body pipeline and relief valve device bonded with it, and main body pipeline one termination source of the gas is the source of the gas end, and the other end is provided with has a stuffy nose or face shield etc. contacts with human body and is use side; The contiguous source of the gas end of relief valve device is made up of valve body, elastic sealed body, directly or by auxiliary member links to each other with the main body pipeline; Elastic sealed body combines with valve body is airtight, elastomer is subjected to less gas pressure and valve body place closure state during normal ventilation, pipeline is serious to be blocked or medical oxygen bleed pressure when inaccessible (common 2 more than the atmospheric pressure) directly acts on elastic sealed body, cause its distortion and break away from valve body, rapid each parts of release guard oxygen regulator of pressure are avoided high pressure and are damaged; Air-flow is flowed out by narrow valve body and produces obvious friction sound (alarm sound) prompting main body pipe blocking or obturation simultaneously.
Press this utility model that such scheme is realized, security protection and prompt functions have ensured carrying out smoothly of oxygen therapy better when making common oxygen delivery pipeline possess obstruction or obturation by innovation structure.
Description of drawings
Fig. 1 is main body pipeline and relief valve device sketch map;
Elastic sealed body broke away from the valve body sketch map when Fig. 2 was pipeline pressurized obturation;
Among the figure: 1 main body pipeline; 2 source of the gas ends; 3 use sides; 4 valve bodies; 5 elastic sealed bodies; 6 elastic sealed body frenulums.
The specific embodiment
Embodiment of the present utility model is as follows:
Embodiment 1:
Main body pipeline: PVC (polrvinyl chloride) flexible pipe; Valve body: ABS (acrylonitrile-butadiene-styrene terpolymer) rigid plastics; Elastic sealed body: silicone rubber; Use side: single hole or diplopore nasal obstruction.
Embodiment 2:
Main body pipeline: PVC (polrvinyl chloride) flexible pipe; Valve body: PS (polystyrene) rigid plastics; Elastic sealed body: silicone rubber; Use side: face shield; Auxiliary member: PVC joint unit.
Claims (3)
1. one kind has the oxygen conveying pipe route main body pipeline of security protection and prompt facility and relief valve device bonded with it to form, it is characterized in that main body pipeline one termination source of the gas is the source of the gas end, the other end is provided with nasal obstruction or structures such as face shield and contacts with human body and be use side; Relief valve device apart from the source of the gas end distance from less than distance use side distance.
2. a kind of oxygen delivery pipeline that security protection and prompt facility are arranged according to claim 1 is characterized in that: relief valve device is made up of directly or by auxiliary member valve body, elastic sealed body and is linked to each other with the main body pipeline.
3. a kind of oxygen delivery pipeline that security protection and prompt facility are arranged according to claim 2 is characterized in that: the elastic sealed body of relief valve device with can reach air-tightness after valve body combines.
