Abstract
The utility model discloses a low-noise oxygen-supply humidifier, which is characterized in that: An air bubble pulverizer is arranged at the outlet of air guide tube of the common medical oxygen-supply humidifier. In addition, a layer of sound-insulating shield sound-absorbing or deadening material is wrapped on the external surface of the humidifying bottle. The utility model efficiently reduces noise of common oxygen-supply humidifier during operation and increases humidity of output oxygen, thus applying to oxygen-supply respirator of hospitals.
Description
Affiliated technical field
This utility model relates to a kind of medical science apparatus of oxygen supply, especially refers to a kind of low noise oxygen supply humidifier.
Background technology
In hospital, will provide oxygen to breathe to the critical patient usually, but the oxygen in the oxygen cylinder be more exsiccant, must feed oxygen in the water to discharge again, has so just increased the humidity of oxygen.But existing oxygen supply humidifier noise is bigger, and reason is that the oxygen bubble that enters in the water is bigger.So just make and give in patient (particularly dyspneic critical patient) the oxygen therapy process that common low noise oxygen supply humidifier produces bigger noise, influences patient's rest the dead of night.
The purpose of this utility model provides a kind of low noise oxygen supply humidifier that noise is little, cost is low of curing by oxygen therapy.
Summary of the invention
For achieving the above object, this utility model comprises the humidification bottle that places the bottom, and humidification bottle is suitable for reading bottle cap, and flow meter and barometric damper are installed on the bottle cap, air inlet is connected with airway by flow meter and barometric damper, is with the bubble destructor in the lower end of airway.The inboard of gas outlet is connected with the internal cavities of humidification bottle, and the humidification bottle outside is with blimp.
Because this utility model has been communicated with a bubble destructor with the lower end of airway, oxygen bubbles bigger in the water can be ground into small oxygen bubble, the humidification bottle outside is with blimp again, thereby noise obviously reduces.Help patient's rest.Also have an advantage in addition, that is exactly because bubble becomes littler, under same oxygen flow prerequisite, has increased the area that oxygen contacts with water, has further increased the humidity of oxygen, helps improving patient's the oxygen uptake level of comfort and the rehabilitation of health.
Below in conjunction with embodiment this utility model is done detailed description further:
Description of drawings
Accompanying drawing 1 is a principle schematic of the present utility model.
Accompanying drawing 2 is bubble destructor sketch maps of the present utility model.
The specific embodiment
In accompanying drawing 1, humidification bottle 1 is in the latter half of whole device, and humidification bottle suitable for reading screwed a bottle cap 2, and air inlet 3, gas outlet 4, flow meter 5, barometric damper 6, airway 7 are installed on the bottle cap 2.Air inlet 3 is connected with airway 7 by flow meter 5, barometric damper 6.The inboard of gas outlet 4 is connected with the internal cavities of humidification bottle 1.Air inlet 3 is connected with the output channel of oxygen cylinder.The outside of gas outlet 4 is connected with patient's oxygen therapy air pipe.Flow meter 5 can be shown to the flow size of patient's oxygen supply.Barometric damper 6 can be regulated the flow size to patient's oxygen supply gas.Be with the bubble destructor in the lower end of airway 7.The bubble destructor can be the cavity of arbitrary shape, and the opening of cavity is connected with the lower end of airway 7.Fig. 2 is exactly the bubble destructor sketch map of another kind of shape, it is the drum shape bubble destructor of being made by two very close fine metal mesh (clear for making figure, tinsel does not draw) fit, and wherein dotted portion is interior bucket, solid line partly is outer bucket, 6 millimeters at the interval between the inside and outside bucket.Should make removable structure between the inside and outside bucket, make it to be convenient to clean (after having grown service time, some impurity will influence the effusion of oxygen to some online little hole plug of fine wire).Such as: and (for example being welded to each other) of making one between upper side 9 of the connected entrance 10 of the bubble destructor 8 of airway 7 fits and bubble destructor (it can directly be made with metallic plate) and the interior bucket three, and outer bucket can be linked on the outer rim of upper side 9, can make the screw thread 11 of several holding screws on the outer rim.Littler for what bubble was pulverized, can also copy said method to increase one deck or multilamellar thin copper wire net, but all will leave certain clearance between each layer thin copper wire net.The fine metal mesh also narrow meshed metal sheet of available densification replaces; The bubble destructor can also be attached on a support cavity with holes (arbitrary shape) surface with sponge, and in order to reduce cost, support cavity can be made with the plastics of cheapness, and this scheme also is convenient to clean (sponge is just taken off and can clean, be very convenient).Owing to become littler behind the bubble process bubble destructor, under same oxygen flow prerequisite, increased the area that oxygen contacts with water (because the area sum of minute bubbles has increased greatly), further increased the humidity of oxygen, help patient's rehabilitation.In order to reduce noise further, also can wrap the blimp that one deck is made by sound-absorbing material or deadener again in the outside of humidification bottle.
Work process of the present utility model is such: the oxygen in the oxygen cylinder enters bubble destructor (the bubble destructor is immersed in the water) by oxygen supply feed channel, air inlet, flow meter and barometric damper, airway, the big oxygen bubbles of airway outlet just becomes small oxygen bubbles through the bubble destructor, and the come-up (this process also is the process of oxygen humidification and the humidity that has increased oxygen) and the water surface noise of overflowing have just diminished from water so again.The oxygen of the effusion water surface provides the oxygen of the humidifying of breathing usefulness to patient by the gas outlet.Overcoat in that layer of the outer bread of humidification bottle made by sound-absorbing material or deadener has reduced noise further.
Claims (3)
1, a kind of low noise oxygen supply humidifier, comprise humidification bottle, humidification bottle is suitable for reading bottle cap, flow meter and barometric damper are installed on the bottle cap, air inlet is connected with airway by flow meter and barometric damper, the inboard of gas outlet is connected with the internal cavities of humidification bottle, it is characterized in that the lower end of airway is connected with the bubble destructor, and the humidification bottle outside is with blimp.
