Abstract
The invention discloses a kind of oxygen inhalation apparatus with low noise, comprising one wetting bottle, air inlet interface, outlet interface, meter and flow regulating valve controlling flow quantity. The wetting bottle is equipped with one vent pipe connected with inlet interface, the lower part of vent pipe is provided with impact-absorbing shell connected with vent pipe, the side wall of impact-absorbing shell is equipped with 3-8 ventilating pores, and the diameter of pore is 0. 5-1 mm. The installed ventilating pores on side wall onf impact-absorbing shell makes oxygen be discharged from different directions and reduces the bubbling noise. The invention is characterized by low noise, low modification cost, simple structure, convenient usage and convenient clean and disinfection. It also prevents bad effect of water flowing into nose or mouth caused by large air bubble and water overflow.
Description
Technical field
The invention belongs to medical instruments field, particularly relate to a kind of low noise oxygen inhaler.
Background technology
Noise, be meant do not need, unmelodious, nervous and deleterious sound.In hospital, noise not only influences patient's rest, also can cause the physiological change of patient's endocrine, cardiovascular and auditory system, and bring negative psychological impact, thereby influence rehabilitation of patients.The standard-required that The World Health Organization (WHO) formulates is that hospital's noise on average is not higher than 35 decibels daytime, is not higher than 30 decibels night.Yet according to relevant research report, a lot of hospitals noise decibel is this critical field head and shoulders above all, and worsens day by day, and hospital's noise has become a global focal issue.
The oxygen anapnotherapy now is widely used in clinical all kinds of patient.Because oxygen need carry out earlier sucking to the patient after humidification, the filtration again, so, in the middle of medical oxygen system and oxygen supply device, be connected with an oxygen inhalation apparatus, oxygen inhalation apparatus comprises a humidification bottle, humidification bottle is provided with intake interface, the flow control valve of the interface of giving vent to anger, effusion meter and control flow, oxygen enters from intake interface, enters underwater in the humidification bottle by breather, enters the oxygen supply device patients via the interface of giving vent to anger that is communicated with humidification bottle again and sucks.Because oxygen bubbling sound is bigger, and increase along with the increase of oxygen flow, thus certain noise pollution produced, particularly evident at night, influenced patient to a certain extent and had a rest and sleep.Especially in the Vasculocardiology Deparment ward, because of the Vasculocardiology Deparment disease belongs to Senile disease, elderly population insomnia incidence rate height, and strong to the sensitivity of noise, this lasting noise has had a strong impact on patient's sleep and rehabilitation, even has patient therefore to refuse oxygen uptake.
Therefore, say in a certain sense how to improve the structure of oxygen inhalation apparatus, reduce the noise of oxygen bubbling as much as possible, become the major issue of improving hospital environment, impelling patient to recover early.As shown in Figure 2, now also there is oxygen inhalation apparatus to be provided with a cylindrical impact-absorbing shell 7 in the lower end of breather 6, be formed with a buffer chamber that is communicated with breather 6 in the impact-absorbing shell 7, the bottom surface of impact-absorbing shell 7 is provided with a plurality of passages 8, the oxygen that enters from breather 6 during through buffer chamber flow velocity slow down, bubble over from passage 8 again, reduce the flow velocity of oxygen by the venthole area that increases oxygen, to reach the purpose that reduces the bubbling noise.But, in practical situation, because a plurality of passage 8 all is on the same bottom surface, so when oxygen when the passage 8 of emerging forms bubbles, have horizontal displacement, a plurality of bubbles can merge air pocket of formation, and air pocket still can produce bigger noise when the water surface breaks.In addition, the sound insulation bottle of humidification bottle being made evacuation is also arranged, but manufacturing cost is very high, is unfavorable for applying.
Summary of the invention
In order to solve above-mentioned technical problem, the purpose of this invention is to provide a kind of low noise oxygen inhaler, have that noise is low, improvement cost is little, simple in structure, easy to use a, advantage such as cleaning-sterilizing is convenient.
To achieve the above object, the present invention has adopted following technical scheme:
A kind of low noise oxygen inhaler, comprise a humidification bottle, humidification bottle is provided with intake interface, the flow control valve of the interface of giving vent to anger, effusion meter and control flow, be provided with a breather that is communicated with intake interface in the humidification bottle, the breather lower end is provided with the impact-absorbing shell that is communicated with breather, the sidewall of described impact-absorbing shell is provided with 8-25 passage, and the aperture of described passage is 0.5mm～1mm, and described passage spacing is not less than 3mm.
The noise that the oxygen bubbling produces mainly contains two kinds, a kind of is the plosive that bubble produces when the water surface breaks, another kind is the noise that breaks and cause water surface vibration to bring at the water surface because of bubble, these two kinds of noises all can increase along with the increase of oxygen flow, increase along with the increase of bubble volume, increase along with the increase of bubble dense degree.We are by being provided with impact-absorbing shell in the breather lower end, a plurality of passages are set on the sidewall of impact-absorbing shell, make oxygen after slowing down through the buffering cavity in the impact-absorbing shell respectively the passage from each different directions discharge, the bubble that produces does not have horizontal displacement directly upwards to emerge, reach the effect of stereo air exhaust, avoid original too high problem of single direction aerofluxus flow velocity, avoided the problem of impact-absorbing shell bottom surface aerofluxus minute bubbles horizontal displacement formation air pocket, reduced the bubbling noise of oxygen; The number and the aperture of restriction passage, be in order both to guarantee certain oxygen flow, avoid simultaneously because passage too much causes gas pressure deficiency in the buffering cavity, make water immerse buffering cavity blocking portion passage, and can't reach the effect that stereo air exhaust reduces noise.Spacing to passage limits, and is the merging for fear of close bubble, avoids the formation of air pocket.
Above-mentioned impact-absorbing shell is cylindric, and described passage is located on the barrel.
Above-mentioned impact-absorbing shell is coniform, and described passage is located on the awl wall.
As preferably, above-mentioned impact-absorbing shell is soft cryptomere, and described passage is located on the cyst wall.
Above-mentioned impact-absorbing shell is to tie up the plastic sheeting air bag that is fixed on the breather lower end.
Above-mentioned impact-absorbing shell is to tie up the latex balloon that is fixed on the breather lower end.
Above-mentioned passage is the passage that some row are vertically arranged.
As preferably, above-mentioned passage number is 10-21.
The present invention is owing to adopted above technical scheme, by a plurality of passages are set on the sidewall of impact-absorbing shell, make oxygen after slowing down through the buffering cavity in the impact-absorbing shell respectively the passage on the variant direction discharge, directly rise after producing bubble, reach the effect of stereo air exhaust, avoided the formation of air pocket, reduced the bubbling noise of oxygen, had that noise is low, improvement cost is little, simple in structure, easy to use a, advantage such as cleaning-sterilizing is convenient.And because avoided the formation of air pocket, the water level fluctuation during oxygen uptake in the humidification bottle slows down, and has avoided because the oxygen flow height causes blister excessive, enters patient's nasal cavity or the oral cavity causes adverse consequences by the interface of giving vent to anger, Oxygen tube.
