Description

Constant pressure and current oxygen generator

This utility model belongs to simple and easy medical instruments field, relates to a kind of voltage stabilization and current stabilization oxygen generator.

In order to solve a small amount of emergency oxygen supply, development and production go out some chemical method Oxygen Generators at present, and as Chinese patent CN86104506A, CN2051863U, CN20546971U etc. have made effort for this reason.But the common weak point of existing Oxygen Generator is that oxygen output flow is difficult to regulate so far.During use, in order to adapt to the different needs of user to oxygen flow, prior living oxygen raw material and the catalyst consumption that designs or estimate to add of having to, what have also must add some accelerator or moderator.Importantly these raw materials are promptly immutable once adding, and the chemical reaction of giving birth to oxygen is by corresponding quantity, and pressure and flow carry out, and can not be regulated as required at any time and can not in time stop midway, and this not only causes unnecessary waste; And in case carelessness reacted strong, pressure is excessive, and explosion might take place Oxygen Generator.

Nearest a patent (90215671.3) thus borrow the Magnet manual adjustment catalyst and the contact area of the liquid of giving birth to the oxygen raw material to regulate the flow that oxygen takes place.This is a progress in the simple and easy Oxygen Generator development.But this method weak point is it require user to note oxygen at any time a situation arises and flow, in time produce the size of the quantity of oxygen with control with the height of hand adjustment joint catalytic body.Because of it is that method is regulated by hand, so its oxygen flow, very uniform and stable.

The purpose of this utility model is to prepare a kind ofly can arbitrarily be started or stop, and the output flow and the air pressure of oxygen need not be paid special attention to by user, but auto-control and oxygengenerating plant stably.It is safe in utilization, and composition is pure suitable medical.

Accompanying drawing is the vertical section sketch map of this oxygen generator.This device is by reative cell (1) as shown in the figure, and control room (2) and gas washing cooling chamber three chambers such as (3) are in series.This three can be discrete also can be coupled as a whole.For sake of convenience, sketch map is a discrete.

Reative cell (1) is by inert plastic, the bottle that metal or glass are made.Wherein the volume of 2/3-3/4 is contained to give birth to oxygen material liquid (hereinafter to be referred as oxygen generating liquid) (4), comprises oxydol H ₂O ₂, or SODIUM PERCARBONATE 2Na ₂CO ₃-3H ₂O ₂, perboric acid is received NaBO ₃The solution that adds the water preparation Deng peroxide.Respective threads on screw thread on its bottleneck of this reative cell (5) and the threaded ring (6) and sealing ring (24) can connect airtight chamber of formation with control room (2), after separating, this reative cell such as other add a bottle cap, can make to give birth to the packing storage-transport vessel of oxygen raw material at ordinary times.

Control room (2) is to use air-locked inert plastic, rubber, and metal, leather or fabric etc. is made retractility, changeable blister cavities of volume (7) or piston type tube chamber.The blister cavities outer housing keeps the blister cavities collimation flexible with framework (8).Connect mutually with catalytic body (10) below the control room top cover (9), this catalytic body is by porous tubular shell (11), and micropore nethike embrane (12) and catalyst pellets piece (13) constitute.Catalyst is also available other manganese of manganese dioxide, ferrum, and cobalt, lead, copper, silver, metallic compounds such as platinum replace.The control locular wall any one, open a venthole (14) and airway (15) and link.On airway, put a gas valve (16) in order to open, the size of closing airway and regulating this place's tube chamber.Airway (15) extends and the trachea (17) of going into of gas washing cooling chamber (3) links.

Gas washing cooling chamber (3) is the container of being made by glass or transparent plastics, and the volume of its 1/2-2/3 fills with aquae destillata or clear water (25), goes into the following termination one network of micropores plug (18) of trachea (17) and immerses under the water surface; The opening of escape pipe (19) is away from the water surface, and outer with oxygen supply sebific duct (20) with have a stuffy nose, nasal tube (21) or mask join.More than each sebific duct should adopt inert silicone rubber tube, guaranteed milk sebific duct or plastic tube.

On control room top cover (9), add the counterweight (22) of Different Weight, on oxygen supply pipe (20), be connected to a gas cooling chamber (23) of alternately separating.

When using this oxygen generator, the reative cell (1) that at first will fill oxygen generating liquid and control (2) connection are a body cavity (be called control--reative cell), open valve (16) then.Gravitate, catalytic body (10) descend to immersing has a certain amount of oxygen to take place then in the oxygen generating liquid, this oxygen rises and is collected in control--in the reative cell, behind the formation certain pressure, flow out by oxygen supply pipe (20) with certain flow.When not needing oxygen supply, then complete valve-off (16), control--reaction indoor oxygen accumulation increases, and the top in control room (9) join same catalytic body (10) rising, and catalytic body and oxygen generating liquid disengage, and the generation of oxygen promptly stops then.The generation of aerobic again when opening valve again.

Open when big when valve (16), have a large amount of oxygen to be discharged by control room (2), its top cover (9) joins same catalytic body (10) and sinks automatically, and oxygen-producing amount thereby increase adapt to the valve of having opened greatly, and bigger flow is provided.In contrast, when valve (16) closes hour, the minimizing that oxygen is discharged by control room (2), gas is at control room internal memory collection, and its top cover (9) joins same catalytic body (10) and rises automatically, oxygen-producing amount thereby minimizing, adapting to the valve that has turned down provides less flow.In addition, when the oxygen generating liquid effective ingredient reduced gradually because of consumption, catalytic body was also correspondingly sunk automatically, the contact area of increase and oxygen generating liquid, thus keep the stable of flow until the oxygen generating liquid approach exhaustion.

As mentioned above, when the control valve size, the quantity that the oxygen of this generating means takes place is automatically to change with the volume in control room is synchronous, so the pressure in the generating means remains constant.Both made because of some accidental cause, during the output channel total blockage of oxygen, the device internal pressure is also still stable, can the too high generation explosion of build-up of pressure danger.

Be fit to the living oxygen raw material of this generating means, kind is extensive, comprising: hydrogen peroxide or hydrogen peroxide (H ₂O ₂), SODIUM PERCARBONATE (2Na ₂CO ₃-3H ₂O ₂), Dexol (NaBO ₃), hydrogen peroxide phosphoamide (NH ₂-CO-NH ₂-H ₂O ₂), and sodium, potassium, ammonium, calcium, barium, peroxide such as magnesium and persulfate etc.Every applications catalyst catalytic decomposition oxygenatedchemicals and the method that produces oxygen all is suitable for this device.

Under the practicality of this oxygen generator for example, the usage range of device is not limited thereto certainly.

Example one:

In reative cell (1), fill one liter of 30% hydrogen peroxide, after connecting with control room (2), opening behind the valve (16) is that aerobic produces valve-off (16) then, oxygen promptly stops to produce, the flow of the oxygen that produces is borrowed pine with user, and the way of tight valve arranges arbitrarily, its scope of arranging is the 0-4000 ml/min, once setting, flow promptly is stabilized in this level, until effective ingredient approach exhaustion in the hydrogen peroxide.Through measurement, 100 liters of one liter 30% hydrogen peroxide common property oxygen, oxygen purity is 99.7%.As flow is arranged is 400 ml/min, then with this stability of flow oxygen supply four hours, is 1500 ml/min as flow is arranged, then with this stability of flow oxygen supply 66 minutes.

Example two:

In fill SODIUM PERCARBONATE 400 gram that contains 13% active oxygen, after adding the reative cell (1) and control room (2) connection of 800 milliliters in clear water, opening valve (16) is that aerobic produces then, valve-off (16), oxygen promptly stops to produce, the flow of the oxygen that produces is used pine with user, the way of tight valve, arrange arbitrarily, the scope of arranging is the 0-2500 ml/min, and once setting, flow promptly is stabilized in this level, until effective ingredient approach exhaustion in the SODIUM PERCARBONATE, 36 liters of SODIUM PERCARBONATE common property oxygen through measuring 400 grams, oxygen purity is that 99.6%. is 400 ml/min as flow is arranged, then with this stability of flow oxygen supply one and a half hours, as flow is arranged is 1500 ml/min, then with this stability of flow oxygen supply 24 minutes.
