Abstract

The utility model relates to a small-sized first-aid oxygen therapy unit which is to obtain oxygen through enforcing electrolysis to the alkaline solution. The first-aid oxygen therapy unit has an electrolysis chamber group which is formed by the series connection of a plurality of electrolysis chambers; the both ends of the electrolysis chamber are exerted direct current power supplies to make each electrolysis chamber become an electrolysis unit; the electrolysis unit separates out hydrogen and oxygen at the both ends of an electrode, and the hydrogen and the oxygen are respectively concentrated in each collection mechanism; in the end, the hydrogen is discharged through a discharging tube, while the pure oxygen is transmitted to patients. The utility model has simple structure, stable operation, and easy processing and manufacturing; the product is in particular suitable for the oxygen emergency of the medical stations (spots) of remote regions and the oxygen supply usage of some anoxic regions.

Description

First-aid oxygen therapy unit

This utility model relates to a kind of small-sized medical resuscitation, and product is suitable for the oxygen first aid of particularly backwoodsman hospital of all kinds of hospitals, medical station (point) and uses as the oxygen supply in places such as high mountain sentry post, mountaineer's base in some anoxia areas.

Existing all kinds of medical first aid oxygen cylinder all needs often bottle to be carried out aeration, and this gives to lack or do not have the medical center, outlying district of oxyen manutactory or work and needs bring very big inconvenience with the place.

The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of and obtains the simple in structure of oxygen and small-sized medical resuscitation that the suitability is wide by alkaline solution being implemented electrolysis process.

For achieving the above object, the technical solution that this utility model adopts is that a plurality of tank house series connection are formed a tank house group, adds dc source at tank house group two ends, makes each tank house become an electrolysis cells.Electrolysis cells is separated out hydrogen and oxygen at the positive and negative two ends of electrode, flow into airway separately respectively, concentrate on then in the set hydrogen or oxygen separator, alkaline matter, steam droplet contained in its chien shih gas separate, cool off with gas, last hydrogen is discharged by delivery pipe, and pure oxygen gas is then failed in the patient.

Below in conjunction with accompanying drawing this utility model is specified.

Fig. 1 is a kind of structural representation of the present utility model.

Fig. 2 is the partial sectional view of electrolyte chamber structure.

With reference to accompanying drawing, this first-aid oxygen therapy unit is equipped with by both sides that electrode 1,2 tank house group, electrolyte conveying mechanism, electric control box, oxygen collection and conveying mechanism and hydrogen are collected and discharging mechanism etc. forms. The tank house group is made up of a plurality of tank houses 4 that connect with the series connection form, and general mode of connecting take 7～9 tank houses is as preferred mode. In each tank house 4, all be provided with the oxygen collecting pipe 5 and the hydrogen collecting pipe 6 that pass into respectively oxygen collector structure and hydrogen collection mechanism. The electrolyte conveying mechanism comprises an electrolyte case 7 and a feed tube 8 of being controlled and passed into tank house 4 by electrolyte case 7. Oxygen is collected and conveying mechanism has an oxygen that is communicated with all tank houses Collecting pipe 5 also passes in an oxygen separator 9 general collection oxygen pipe 10, is provided with oxygen carrier pipe 11 in the upper end of oxygen separator 9, is provided with the liquid back pipe 12 that is communicated with tank house 4 in the lower end of oxygen separator 9. Hydrogen is collected and conveying mechanism has one and is communicated with the hydrogen collecting pipe 6 of all tank houses and passes in a hydrogen separator 13 general collection hydrogen pipe 14, be provided with hydrogen delivery pipe 15 in the upper end of hydrogen separator 13, be provided with the liquid back pipe 12 that is communicated with tank house 4 in the lower end of hydrogen separator 13. During work, the alkaline solution in the tank house 4 is after electrolysis, and two electrode iron plates are held precipitated oxygen gas and hydrogen gas from it, and two kinds of gases are delivered in oxygen separator 9 and the hydrogen separator 13 through oxygen collecting pipe 5 and hydrogen collecting pipe 6 respectively. After contained alkaline matter and aqueous vapor droplet separated through

separator

9,13 in the gas of input, the pure oxygen gas of gained was sent to the patient through oxygen carrier pipe 11, and the hydrogen of gained is then discharged through hydrogen delivery pipe 15.

Separator

9,13 bottom topping up can prevent gas backstreaming effectively, play safety assurance, and the unnecessary liquid in interior passes back into tank house 4 finally by crossing liquid back pipe 12. Generally can adopt NaOH (NaOH) or potassium hydroxide (KOH) solution as electrolyte in the use. When in the tank house 4 during fluid low, open electrolyte case 7, make the liquid in the case be transported to tank house 4 through feed tube 8. Utilize electric box 3 with 220 volts of AC rectifications and with behind the silicon-controlled voltage regulation, direct current is put on the electrode 1,2 at tank house group two ends, also can directly adopt storage battery power supply. Regulate the panel knob on the electric box 3, make output voltage big little adjustable, thereby can control the size of output oxygen amount. Generally according to medical standard, output oxygen value should be 2～4 liter/mins. For making things convenient for the use of product, the oxygen therapy device body can be inserted in a casing 23 with castor 22, is provided with cross-over block 24 between tank house group and the casing 23, can make so whole oxygen therapy device be easy to move and carry.

The specific constructive form of tank house 4 as shown in Figure 2, it has a cavity that has the iron ring flange 17 of asbestos cloth 16 to consist of by riveted joint between sidewall, be pressed into the battery lead plate 18 of its aperture that gathers at the middle part of cavity, rivet by the iron plate 20 of cushion block 19 and its aperture that gathers respectively both sides at battery lead plate 18, is provided with gas port 21 on the top of ring flange 17. When electrolyte from electrolyte case 7 after feed tube 8 flows into the tank houses 4, be covered with electrolyte in the whole tank house 4, the hydrogen of separating out, carrier of oxygen can be concentrated to electrode separately by the aperture that gathers on battery lead plate 18 and the iron plate 20, gas port 21 finally by cavity ring flange 17 tops concentrates in the collecting pipe 5,6 of oxygen and hydrogen, number in the figure 25,26 is connection rivet, and 27 is collets.

The utility model processing and manufacturing simple in structure, easy, stable operation, easy to maintenance, its purity 99.9% of oxygen of producing by it.

Embodiment: be made into aqueous solution between 1.20～1.25 with sodium hydroxide (NaOH), in tank house, through the unidirectional current effect, make alkaline aqueous solution be able to electrolysis, thereby constantly separate out hydrogen, oxygen on the pole plate both sides,

At negative electrode on one side: 2H ⁺+ 2e=HH ↑;

At anode on one side: 2(OH) ⁺+ 2e=H ₂O+ 1/2 O ₂↑.

Sodium hydroxide does not consume in solution, only plays electric action, and water then constantly is electrolyzed to produce hydrogen or oxygen gas.Water per hour consumes about 1 kilogram in electrolytic process approximately.
