Abstract

The utility model relates to a portable adjustable chemical oxygen production and supply device, which is provided with a cuboid housing. The bottom of an upper container is provided with a connecting port, and the left rear upper part of a lower container is provided with a connecting port. The connecting ports are connected by a plastic pipe with a Murphy's dropping tube, and the plastic pipe penetrates through a squeezing valve. The right rear upper part of the lower container is provided with a connecting port which is connected with oxygen inlets of two humidifiers by a flexible pipe, and the two humidifiers are connected with each other in series and arranged on the right side of the housing. The left rear upper corners of the upper and the lower containers are respectively provided with a connecting port, and the connecting ports are connected with each other by a flexible pipe. Oxygen producing agent is filled in the upper container, and catalytic agent is filled in the lower container. The utility model has the characteristics of big oxygen production amount, long oxygen supply time, adjustable flow quantity and time of oxygen supply, small size, light weight and portability.

Description

A kind of portable adjustable chemical oxygen generation apparatus of oxygen supply

This utility model relates to therapeutic medical apparatus of oxygen supply, is specially adapted to not have the rural health institute of large-scale oxygen supply equipment, and unit infirmary and family need the patient of oxygen therapy.

As number of patent application is that " disposable micro produce oxygen device " disclosed technology of 912005564 is one and is positioned at the dress water that soft housing centered on by regenerative agent and the sealed glass container of catalyst, though be easy to carry, but producing oxygen flow only is 200～300 milliliters of per minutes, oxygen flow is non-adjustable, oxygen supply time also has only 5 minutes, requires the very far away of (at least 1000～2000 milliliters of per minute oxygen flows) difference from clinical treatment.Another number of patent application is that 912016515 " portable chemical oxygenerator " is that cooling water, catalyst and regenerative agent are combined into one, an action just can be produced oxygen, it is even to produce oxygen speed, volume is little, in light weight, but still exist oxygen-producing amount few (only 8000 milliliters), defectives such as oxygen supply time is short, and oxygen flow is non-adjustable.

The purpose of this utility model is to provide a kind of easy to carry to the public, and oxygen flow, the time is adjustable, the portable adjustable chemical oxygen generation apparatus of oxygen supply of oxygen supply longer duration.

Scheme of the present utility model is: make shell (12) with the iron plate of 1 millimeters thick, adorn upper and lower two containers (1), (2) in the shell (12); Interface (5) is arranged at upper container (1) bottom, and there is interface (6) the left back top of following container (2), is with the plastic conduit (7) of Murphy's burette (9) to pass squash type valve (a 10) connecting interface (5) and interface (6) with one; There is an interface (19) the right back top of following container (2), is the oxygen feeder (21) of the humidifier (11) of series connection with a flexible pipe (20) connecting interface (19) and two on shell (12) right side; Upper and lower container (1), (2) left back angle of going up has an interface (22) respectively, and the two connects with a flexible pipe (24); The right back inferior horn of following container (2) has the waste liquid outlet (13) that can open/close; Upper container is put oxygen-making agent in (1), and following container is put catalyst.

The utility model has the advantages that: oxygen flow, the time is adjustable, and squash type valve (10) is opened back beginning oxygen supply in 10 seconds, closes squash type valve (10) and promptly stops oxygen supply at once; Squash type valve (10) but step-less adjustment flows into the speed of container (2) down with the control oxygen-making agent, thereby the speed of oxygen is produced in control, makes oxygen flow arbitrarily adjustable in 0～6000 milliliter of scope of per minute; The interior oxygen-making agent of Murphy's burette (9) drips number can distinguish speed and the oxygen output flow that reflects container (2) under the oxygen-making agent inflow intuitively with the bubble in the humidifier (11); Oxygen making amount is big, and maximum can reach 6000 milliliters of per minutes; Oxygen supply time is long, fills up the sustainable low discharge oxygen supply of oxygen-making agent and catalyst (1000～2000 milliliters of per minutes) 5 hours at every turn; Volume is little, and is in light weight, is beneficial to and carries.

Embodiment 1

The preparation of oxygen-making agent: get multiethylene-glycol phosphate (PH (CH ₂CH ₂) _nO) ₃-PO1 gram, the hydrogen peroxide H of adding 30% (V%V) ₂O ₂5000 milliliters, make it to dissolve fully, it is standby to keep in Dark Place.

Preparation of catalysts: get potassium permanganate KMnO ₄20 grams add 1000 milliliters of distilled water, and it is standby to keep in Dark Place after the dissolving fully.

Make a rectangle shell (12) with 1 millimeters thick iron plate, the supporting clapboard of one band opening is installed at height 2/3rds places, shell (12) is divided into two lattice, upper container (1) is placed on lattice, following container (2) is placed on down lattice, upper and lower container is all made the cuboid hollow container with transparent plastic, and a projection band external screw thread opening (14) is arranged on the upper left side of upper and lower container (1), (2), and the outside has a tapped vinyl cover (15) to cooperate with it; Shell (12) is positive opens two rectangle windows (16), (17) respectively over against the position of upper and lower container (1), (2), so that observe the amount of the interior oxygen-making agent of upper container (1) and the amount of interior chemical reaction that takes place of following container (2) and waste liquid generation; Plastic conduit (7) with a band Murphy's burette (9) passes the interface (5) of squash type valve (10) connection upper container (1) and the interface (6) of following container (2), and Murphy's burette (9) is installed in above the support (18) in shell left side; The right back top of infra container (2) has an interface (19), with a flexible pipe (20) connecting interface (19) and two oxygen feeders (21) that are the humidifier (11) of series connection that are installed in the shell right side; The right back inferior horn of following container (2) is opened the waste liquid outlet (13) that can open/close, is in air-tight state during oxygen supply; The angle also has interface (22), (23) on upper and lower container left back, and the two connects with a flexible pipe (24) makes upper and lower container (1), (2) internal pressure keep balance; In the positive position of shell (12), open hole, a garden and one turn-knob (25) is installed and is joined with the adjusting screw(rod) of squash type valve (10) over against squash type valve (10); Two humidifiers in shell right side (11) are added 1/3～1/2 amount normal saline; Upper container (1) adds sharp 3500 milliliters of system oxygen, and following container (2) adds 350 milliliters of catalyst; Open valve turn-knob (25) and can see following of oxygen-making agent is arranged in the Murphy's burette (9), have oxygen bubble to occur to begin oxygen supply in the humidifier; Tighten valve turn-knob (25) after oxygen supply finishes, waste liquid outlet (13) is opened, discharge container (2) waste liquid down, again oxygen-making agent and catalyst are added upper and lower container (1), (2) respectively in order to using next time.
