Description

Personal medical convenient device for producing oxygen

The utility model is a kind of modified of miniature Iatrochemistry oxygen generator, can improve oxygen quality on the basis of further miniaturization, and the Stable Oxygen gas velocity is realized the uninterrupted oxygen that produces.

The medical oxygen generator that makes things convenient for of individual claims micro medical chemistry oxygen generator again, is used for individual or family's oxygen supply, at home and abroad have and study widely and use, many patent applications (as Chinese patent 88205012,90206717 etc.) are arranged every year, all have every year new product to come out.Visible " Chinese medical apparatus magazine " the 1st phase in 1989 of its basic principle or relevant article of the 5th phase of nineteen ninety.

The chemistry regenerative agent under the control of catalyst, oxygen release in oxygen-generating chamber, oxygen be cleaned with humidifying after can smoke.The quality that guarantees oxygen is one of key problem in technology of this series products.Method commonly used is to adopt mechanical filter and water washing cleaning respectively or simultaneously.The purification water consumption of common product is big at present, has increased the volume and weight of oxygen generator.When clean room and oxygen-generating chamber dispose up and down, flow into oxygen-generating chamber for preventing to purify waste water, the admission line design of clean room is comparatively complicated.

For the ease of carrying, tend to this type of product design is got less at present, each oxygen-producing amount also reduces thereupon, produces the oxygen time to shorten.Though reusable, the raffinate behind the use pre-treatment product oxygen cleans oxygen-generating chamber, changes regenerative agent and catalyst, replenishes cooling water or purifies waste water normal palpus several minutes.This is for continuous product oxygen, and not only inconvenience is also dangerous for patient.

Task of the present utility model is to adopt innovative design, is helping on the basis of miniaturization, improves the oxygen depuration quality of this series products, and the Stable Oxygen throughput shortens the blanking time when repeating to produce oxygen.

Design main points of the present utility model are: during 1, the oxygen process of oxygen-generating chamber's generation fibre bundle conveniently replaced or cleaning enters and purifies waste water.Utilize fibre bundle that oxygen is filtered, the output speed of balanced oxygen, and separate oxygen-generating chamber and purify humidification bottle.2, two oxygen-generating chamber that can be sleeved on are together used in one after the other, realize the uninterrupted oxygen that produces.Be described in detail it below in conjunction with accompanying drawing.Fig. 1,2 is structural representations of two kinds of embodiment.Fig. 3 is the partial enlarged drawing of fibre bundle.

With reference to Fig. 1, the medical oxygen generator that makes things convenient for of typical individual has two identical oxygen-generating chamber (1) and a purification humidification bottle (2) to constitute.Oxygen-generating chamber (1) top is bigger, and the bottom is less, is tubbiness or cup-shaped, can be sleeved on together at ordinary times.Chemistry regenerative agent and catalyst are put into oxygen-generating chamber (1) and are produced oxygen.The water of packing in the oxygen-generating chamber (1) dissolves regenerative agent on the one hand, is used for absorbing the heat that discharges when producing oxygen on the other hand.Oxygen-generating chamber (1) processes with medical plastic, aluminium or stainless steel, wall thickness 0.05-0.2cm.How many volumes is decided according to each oxygen-producing amount.Suppose each product oxygen 10-15L, then volume is 0.5-1.5L.There are garden shape opening (3), bore 5-10cm in oxygen-generating chamber (1) upper end.

With reference to Fig. 1, purify humidification bottle (2) and place oxygen-generating chamber (1) top, but also can and purify about humidification bottle (2) or front and back configurations (not drawing among the figure) oxygen-generating chamber (1).The bottom (4) of purification humidification bottle (2) is installed in the opening (3) of oxygen-generating chamber (1) and locates, and rib collar or bayonet socket are tightly connected.Purify humidification bottle (2) and process with transparent plastic, thick 0.1-0.2cm, garden column type or rectangle, volume 50-150ml, except that bottom (4), external diameter is slightly smaller than opening (3).With reference to Fig. 3, (4) have interface (5) in the bottom, and garden shape is charged into the interior 1-4cm of oxygen-generating chamber (1), is tightly connected with oxygen exhaust (6) rib collar or bayonet socket.Oxygen exhaust (6) is used plastic processing, garden vertebra type.Conical pipe (8) makes progress external diameter 0.4-1cm, long 0.5-2cm, middle aperture (7) aperture 0.1-0.8cm at the middle part.Thin-walled sebific duct (9) is inserted in vertebra shape pipe (8) upper end.Thin-walled sebific duct (9) is made with rubber or latex, and wall thickness 0.05-0.2cm, long 1-3cm, internal diameter 0.3-0.8cm, the other end are enclosed within fibre bundle (10) lower end.The long 0.4-3cm of fibre bundle (10), external diameter 0.3-2cm, garden shape or flat wiper blade shape are formed by several thousand long fibre ligation one ends, and the ligation end is inserted in thin-walled sebific duct (9).Long fibre can be selected animal wool (as pig, horse, sheep etc.), the string (as fiber crops, palm fibre, silk etc.) of cleaning for use, also can adopt metal (as aluminium, stainless steel wire etc.) or macromolecular material (as plastics, nylon yarn etc.), but the thickness of single fiber should be similar to above-mentioned animal and plant fiber.The ligation end is not fluffy for fibre bundle (10), is immersed in the water that purifies humidification bottle (2) bottom.

Below in conjunction with accompanying drawing, introduce the medical dynamic duty process that makes things convenient for oxygen generator of individual: at first carry out and produce oxygen preparation, in purifying humidification bottle (2), inject clean water from the upper end, add to the 1/2-2/3 place of its volume.Regenerative agent (as SODIUM PERCARBONATE), water, catalyst (as manganese dioxide) are put into an oxygen-generating chamber (1), install and purify humidification bottle (2).With reference to Fig. 1, Fig. 3, oxygen enter the cavity of thin-walled sebific duct (9) and fibre bundle (10) lower end by aperture (7), conical pipe (8).(10-50cmH when oxygen reaches certain pressure ₂O), oxygen is along the space between thin-walled sebific duct (9) and the fibre bundle (10), along rising on the inner space of fibre bundle (10), and oxygen forms tiny oxygen bubbles by fluffy fibre bundle (10) upper end, evenly enters to purify in the humidification bottle (2).By fibre bundle (10) time, oxygen is filtered, and in purifying humidification bottle (2), again by water washing cleaning, cleans moistening oxygen and exports by oxygen uptake apparatus (11).

Because fibre bundle (10) has certain gas-flow resistance, will limit the oxygen of oxygen-generating chamber (1) generation and overflow rapidly, oxygen is discharged more reposefully.Because fibre bundle (10) lower end is by thin-walled sebific duct (9) clamping, the water that purifies in the humidification bottle (2) is difficult to splash in the oxygen-generating chamber (1); In like manner, when oxygen-generating chamber (1) tilts and even 90 degree of short duration when toppling over, its content also is difficult to enter and purifies humidification bottle (2).

As oxygen uptake continuously, when producing oxygen, second oxygen-generating chamber (1) carried out produce the oxygen preparation in first oxygen-generating chamber (1), in case first has produced oxygen, will purify humidification bottle (2) rapidly and move in second oxygen-generating chamber (1), continue to produce oxygen.Clean first oxygen-generating chamber (1) this moment.Produce only several seconds kinds of oxygen interval for twice.After producing oxygen, two oxygen-generating chamber (1) still are sleeved on together.It is standby to unload fibre bundle (10) cleaning, or changes.The reusable long period of fibre bundle (10).

To purify humidification bottle (2) and take off, and put upside down, and pour in the oxygen-generating chamber (1) by opening (3), its bottom (4) still is stuck in outside the opening (3) of oxygen-generating chamber (1).Like this, can reduce the volume of whole oxygen generator, be convenient to packing and carry.

Filtration oxygen is not only in the effect of fibre bundle (10), also separates oxygen-generating chamber (1) and purifies humidification bottle (2), makes the latter's very letter refining of design.Swinging, still can producing oxygen when tilting, improved the reliability that this oxygen generator uses at the volley.Because oxygen-generating chamber (1) is a combined type with purifying humidification bottle (2), can use expedient material to do oxygen-generating chamber (1); With reference to Fig. 2, available aluminum canteen is done oxygen-generating chamber (1), and need only design bottom (4) rib collar that purifies humidification bottle (2) to such an extent that get final product with the opening of above-mentioned aluminium kettle is supporting this moment.Because this aluminium kettle sends to the individual in army, also have commercially availablely, find two identical aluminium kettles alternately to do oxygen-generating chamber (1) easily, this individual soldier or individual oxygen supply for army is convenient especially.

Manufacture fibre bundle (10) and draw materials extensively, processing is simple, and cost is low, cleans easily and changes.As hard material (metal, plastics etc.) is processed into the surface many strias are arranged, there are many micropores inside, or rolls with wire netting, corrugated plate, replaces fibre bundle (10), also can produce similar effect, but complex process, the cost height.We once tried out materials such as sponge, foamed plastics, and it is good that effect all is not so good as fibre bundle (10).

In a word, because the utility model uses fibre bundle (10) in oxygen-generating chamber (1) with purifying humidification bottle (2) intersection, make the medical oxygen quality of oxygen generator that makes things convenient for of individual better, oxygen flow is stable.Reduced the purification water consumption, simplified purification humidification bottle (2) design, whole oxygen generator is smaller and more exquisite.Improved the reliability of using in the motion.Use two oxygen-generating chamber (1) that can be sleeved on together, make the interval of producing oxygen for twice have only several seconds, to oxygen-producing amount what, produce the length of oxygen time and select more convenient.These measures can be widely used in all kinds of small-sized Iatrochemistry oxygen generators, and the utility model will have application promise in clinical practice.
