Abstract
The utility model discloses a portable micro oxygen supply device which comprises an oxygen bottle, a reducing valve, an oxygen supply pipe and a nose chock plug, wherein a switch valve is arranged on a gas inlet and outlet pipe of the oxygen bottle; a sealing joint seat is arranged at a port of the gas inlet and outlet pipe; a sealing joint, a gas-pressure meter and a quick coupler are arranged on the reducing valve; the sealing joint is matched with the sealing joint seat; the reducing valve is communicated with the oxygen bottle via the sealing joint seat and the sealing joint; one end of the oxygen supply pipe is communicated with the reducing valve via the quick coupler; the other end of the oxygen supply pipe is communicated with the nose chock plug; and the nose chock plug is internally provided with a gas inlet one-way valve and a gas outlet one-way valve.The oxygen supply device is small in size, light in weight and convenient to use, the weight of the oxygen bottle does not exceed 0.5kg, gas can be filled repeatedly for many times, the gas storage of one oxygen bottle can be used for approximately 1h by an adult, and the oxygen supply device is very suitable for personnel in industries of medical first aid, mountaineering, drowning rescue and the like.
Description
Technical field
This utility model relates to a kind of apparatus of oxygen supply, relates to specifically a kind of Protable mini-size oxygen-feeding device.
Background technology
As everyone knows, traditional oxygen supply is made up of high-pressure oxygen cylinder, air relief valve, oxygen catheter and face shield conventionally, although this oxygen supply storage oxygen amount is large, but its complex structure, heavier, people carry, use very inconvenient, therefore, it can only be for professional, and the scope of application is very limited.
Utility model content
For above-mentioned the deficiencies in the prior art, the purpose of this utility model is to provide a kind of volume Protable mini-size oxygen-feeding device little, lightweight, easy to use.
To achieve these goals, the technical solution adopted in the utility model is: a kind of Protable mini-size oxygen-feeding device, be made up of oxygen cylinder, air relief valve, oxygen catheter and nasal obstruction head, the turnover trachea of described oxygen cylinder is provided with controlled valve, is provided with seal nipple seat at the port of turnover trachea; Described air relief valve is provided with seal nipple, air gauge and ready-packaged joint, and seal nipple and seal nipple seat match, and air relief valve is connected with oxygen cylinder by seal nipple seat and seal nipple; One end of described oxygen catheter is connected with air relief valve by ready-packaged joint, and the other end of oxygen catheter is connected with nasal obstruction head; In described nasal obstruction head, be provided with breather check valve and outgassing nonreturn valve.
Preferably, described oxygen cylinder is miniature gas cylinder, and its bottle is heavily not more than 0.25kg.
Further, described breather check valve and outgassing nonreturn valve are unidirectional valve.
Adopt the utility model of the technical program, its beneficial effect is: oxygen supply volume of the present utility model is little, lightweight, easy to use, the weight of its oxygen cylinder is no more than one jin, a traditional unit of weight, and can repeatedly repeat aeration uses, the air storage amount of one bottle of oxygen cylinder can, for an adult about 1 hour, be suitable for the tradesmans such as medical first aid, expedition and weak water relief and use very much.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model;
Number in the figure: 1, oxygen cylinder; 2, air relief valve; 3, oxygen catheter; 4, nasal obstruction head; 11, controlled valve; 12, seal nipple seat; 21, seal nipple; 22, air gauge; 23, ready-packaged joint; 41, breather check valve; 42, outgassing nonreturn valve 42.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Referring to Fig. 1, Protable mini-size oxygen-feeding device of the present utility model, is made up of oxygen cylinder 1, air relief valve 2, oxygen catheter 3 and nasal obstruction 4, and the turnover trachea of described oxygen cylinder 1 is provided with controlled valve 11, is provided with seal nipple seat 12 at the port of turnover trachea; Described air relief valve 2 is provided with seal nipple 21, air gauge 22 and ready-packaged joint 23, and seal nipple 21 matches with seal nipple seat 12, and air relief valve 2 is connected with oxygen cylinder 1 by seal nipple seat 12 and seal nipple 21; One end of described oxygen catheter 3 is connected with air relief valve 2 by ready-packaged joint 23, and the other end of oxygen catheter 3 is connected with nasal obstruction 4; In described nasal obstruction 4, be provided with breather check valve 41 and outgassing nonreturn valve 42.Described oxygen cylinder 1 is miniature gas cylinder, and its bottle is heavily 0.22kg.Described breather check valve 41 and outgassing nonreturn valve 42 are unidirectional valve.
When use, oxygen catheter 3 is connected on the ready-packaged joint 23 of air relief valve 2, then the seal nipple of air relief valve 2 21 is docked with the seal nipple seat 12 of oxygen cylinder 1, open the controlled valve 11 of oxygen cylinder 1, adjust tolerance by air relief valve 2 simultaneously, can be by nasal obstruction 4 oxygen supply.Certainly, oxygen supply also can have a stuffy nose 4 and adopt other face shield oxygen supply, the oxygen reserves in its oxygen cylinder 1 to learn by the air gauge 22 on air relief valve 2, does not specifically just repeat at this.
Above are only a kind of embodiment of the present utility model, not in order to limit this utility model, all any amendments of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection domain of the present utility model.
