The oxygen inhalator for a hyperbaric oxygen chamber comprises an oxygen source, an oxygen therapy pipe and an oxygen absorption valve. The utility model is characterized in that each branch point of the oxygen therapy pipe in a chamber is provided with an oxygen buffer tank with a filter; an opening of the side wall of the oxygen buffer tank is connected with a rocker valve of an oxygen absorption valve with a dynamic display; the outlet of the oxygen absorption valve is connected with an oxygen inhalation mask by an oxygen spraying humidifier with data logging equipment. The oxygen absorption equipment provided by utility model makes importing oxygen decontaminated and humidified and makes the importing oxygen resistance decrease.

Description

A kind of hyperbaric oxygen chamber oxygen uptake equipment

This utility model relates to the interior patient of a kind of oxygen uptake equipment, particularly hyperbaric oxygen chamber and uses oxygen uptake equipment.

Be higher than the airtight manned pressure vessel of an absolute atmosphere---in the hyperbaric oxygen chamber by the cabin in the oxygen supply oxygen supply be technique known, the oxygen supply mode that is adopted in the hyperbaric oxygen chamber is earlier hyperbaric oxygen to be fed the lateral that connects each oxygen absorption mask through the oxygen therapy trunk line at present, be connected with the suspended body flowmeter of Oxygen respiratory valve and signal patients accepting oxygen inhalation situation on each lateral respectively, this oxygen supply mode can cause that the oxygen therapy resistance increases, each lateral upward pressure imbalance because of the prolongation of pipeline and branch road need dispose suspended body flowmeter, thereby strengthens the patients accepting oxygen inhalation resistance.In addition, prior art does not solve the dry laryngopharynx malaise symptoms that patient occurs after because of the long period oxygen uptake yet.

The purpose of this utility model is to overcome above-mentioned defective of the prior art, and provide a kind of rational in infrastructure can make oxygen therapy pressure relatively steadily, declines of oxygen uptake resistance, no oxygen uptake malaise symptoms, can show the patients accepting oxygen inhalation situation synchronously oxygen uptake equipment a kind of with low cost, particularly hyperbaric oxygen chamber with oxygen uptake not fully.

For achieving the above object, this utility model provides a kind of like this hyperbaric oxygen chamber oxygen uptake equipment, it comprises oxygen source, oxygen therapy pipeline and Oxygen respiratory valve, it is characterized in that, each bifurcation of oxygen uptake pipeline is installed the oxygen surge tank that has filter in the cabin, this surge tank sidewall opening links to each other with the rocking bar valve of the Oxygen respiratory valve that has dynamic display, and the outlet of Oxygen respiratory valve concentrates the oxygen atomization humidifier of automatic controller to be connected with oxygen absorption mask by band.

Below in conjunction with accompanying drawing technical scheme that this utility model is carried is described in further detail:

Fig. 1 is a hyperbaric oxygen chamber oxygen uptake equipment sketch map.

At first, feed in the cabin in advance hyperbaric oxygen in the oxygen supply take-off line of telling for every patient by oxygen catheter, at each take-off line place the airtight oxygen surge tank 1 that volume is 500-1000ml is installed, the pressure of take-off line is kept relative stability, overcoming the phenomenon that prolongs the oxygen uptake resistance increasing occurs owing to pipeline.Oxygen intake end 2 places, surge tank bottom are provided with one and are fixed in its aperture of tank base greater than 200 purpose drainage screens 3, with the impurity in the elimination oxygen.

Surge tank 1 has two openings, and one is equipped with oxygen gauge 4, changes with indicated pressure, and another opening links to each other with Oxygen respiratory valve 7 by rocking bar valve 5.

On the pressure-sensitive diaphragm 6 of Oxygen respiratory valve 7 photoelectricity shutter body 8 is housed.Oxygen respiratory valve 7 tops are fixed with infrared emission-collecting electrode 9.Photoelectricity shutter body 8 with the upper and lower displacement of pressure-sensitive diaphragm from inserting between infrared emission-collecting electrode 9 or shifting out.Photoelectricity shutter body 8 is formed infrared photoelectric sensor 11 with infrared emission-collecting electrode 9.During patients accepting oxygen inhalation, hypostegal cavity 10 pressure descend, and diaphragm moves down, and photoelectricity hides body 8 and descends thereupon, and is unimpeded between the emission-collecting electrode.At this moment, green indicating lamp is luminous, shows oxygen uptake; When patient exhales, hypostegal cavity 10 pressure increase, and move on the diaphragm to reset, and photoelectricity shutter body 8 rises, and inserts between the emission-collecting electrode, covers emission electrode, and red led is luminous.Oxygen respiratory valve 7 links to each other with dynamic display 12 by infrared photoelectric sensor 11, and oxygen uptake or breath signal that dynamic display 12 is sent infrared photoelectric sensor 11 show by red, green dichromatism display lamp, with synchronous remote measurement patient's oxygen uptake situation.

Oxygen uptake equipment described in the utility model, its feature also is, the outlet 13 of Oxygen respiratory valve 8 links to each other with jetting type oxygen atomization humidifier 14, but described jetting type atomizing humidifier 14 is hermetic containers that spatial water-filling is left on top, the container top opening inserts high-speed jet formula nozzle 15, upper end of nozzle links to each other with atomizing oxygen source 16 through pipeline, electromagnetic valve 17 is housed the atomized oxygen pipeline and/or manual modulation valve 18 links to each other with the controller 19 that atomizes automatically of concentrating that places the total platform of control, the big I of atomization quantity is regulated according to patient's needs, when not needing atomizing humidifying performance, then close this valve, this moment, no oxygen fed atomizing humidifier 14, and this atomizing humidifier 14 does not start.In the atomizing humidifier 14, conduit 21 in one usefulness container side wall support, the 20 fixed insertion water is arranged with respect to nozzle 16 places.These humidifier 14 tops two STHs, an end are that air inlet 22, one ends are venthole 23 straight-through oxygen absorption masks 24.When atomizing source of the gas 16 during to spray injector high speed aerating oxygen, the nozzle place forms a negative pressure, can and be atomized into the small water droplet that is full of the container upper space with the water sucking-off in the conduit in the water 21, thereby behind the dry oxygen humidification with the air inlet input, export oxygen absorption mask 24 to by venthole 23.

The utility model has following advantage owing to having the said structure feature:

1, because the oxygen of having installed with filter cushions tank, makes the oxygen of main oxygen therapy pipeline Be so incensed that purification, and gas pressure is from start to finish kept relative stability, thereby reduced Patient's oxygen uptake resistance.

2, owing at Oxygen respiratory valve infrared photoelectric sensor has been installed, and make its connection The oxygen uptake dynamic display can constantly be received patients accepting oxygen inhalation, breath signal, so that synchronously distant Survey patient's oxygen uptake situation.

3, the band installed of this utility model is concentrated the jetting type oxygen atomization humidifier of automatic controller, can be according to outputing to oxygen absorption mask behind the dry oxygen humidification of patient's needs with input, the patients oxygen uptake, this has eliminated the malaise symptoms such as dry laryngopharynx that patient occurs after because of the long period oxygen uptake.
