Description
Technical field
The present invention relates to a kind of oxygen humidifying device that patient's oxygen intake uses in the medical field, particularly a kind of disposable use oxygen humidifying filter.
Background technology
In medical field, oxygen therapy is a kind of important medical measure that rescues the critical patient, and the oxygen humidifying device in its oxygen delivery equipment is one of requisite armarium of hospital.Use the research of oxygen humidification bottle and test to show through the medical research worker to present: oxygen humidification bottle is very easily by patient contamination, and its inner core is to cause the risk factor that infects; Wherein the pollution of humidification fluid is to cause one of main pathogen of patient pulmonary repeated infection, the infection of humidification fluid often since oxygen impure cause.Also there is repeated disinfection in the use in the oxygen humidifying device that uses at present and aged gradually problem, thus the generation of the explosion malpractice that causes " humidifying cup " in use.For solving this kind defective; Chinese patent 200820060637.x discloses a kind of disposable oxygen humidifier; Comprise oxygen feeder, oxygen exhaust, humidifying filtering container, waterproof ventilated membrane and seal cover; Wherein oxygen feeder is positioned at an end of humidifying filtering container, and seal cover and oxygen exhaust are positioned at the other end, and waterproof ventilated membrane is positioned at the inside of humidifying filter and bonding with the bottle inwall.The disposable oxygen humidifying filter that this patent proposes has solved and has reused the problem that humidifies glass explosion, but does not solve the contamination phenomenon of humidification fluid and oxygen humidification bottle up hill and dale.Although this patent has proposed the application of waterproof ventilated membrane; But owing to receive the restriction of water repellent filter membrane material and do not propose how to install; Must cause part of oxygen can walk around waterproof membrane directly gets in the humidification fluid; Not only can cause the pollution of humidification fluid, the more important thing is the pure of the oxygen that can not guarantee to flow to the patient reliably.
Summary of the invention
The technical issues that need to address of the present invention provide and a kind ofly can effectively intercept humidification fluid; Filter pathogenic microorganism, avoid cross infection, increase the contact area and the time of contact of oxygen and humidification fluid; Improve the humidifying effect, guarantee the comfortable safe disposable use oxygen humidifying filter of patient's oxygen uptake.
For solving the problems of the technologies described above, the technical scheme that the present invention taked is:
Disposable use oxygen humidifying filter; Oxygen filter membrane, the splendid attire that comprises oxygen feeder, processed by politef or modified Teflon, expanded PTFE and composite thereof contain the filter bottle of epsilon-polylysine antibacterial or V80 antibacterial or Dobell's solution humidification fluid, with the loam cake that matches suitable for reading of filter bottle and be arranged on the oxygen exhaust that the nasal oxygen tube that covers or oxygen absorption mask are connected; Said oxygen filter membrane is positioned at the filter bottle body bottom; Through mould overcoat horizontal fixed, the oxygen outlet end of oxygen feeder stretches in the mould overcoat and is positioned at the below of oxygen filter membrane.
The further concrete structure of mould overcoat of the present invention is: the mould overcoat is that wall is provided with the annulus that has air-vent on screw thread, the end face, and oxygen filter membrane level is adjacent in the annulus end face and the nut compressing through cooperating with the mould sleeve thread.
The further concrete structure of the nut of technique scheme is: be provided with the cavity of arc lower in the nut with the outer inner room of mould, the oxygen outlet end of oxygen feeder stretches in the cavity.
Further improvement of the present invention is: said oxygen feeder is arranged on and covers; Oxygen feeder is internally connected with oxygen input tube; Oxygen input tube is positioned at bottle and is connected with the inside of oxygen feeder; The bottom of oxygen input tube is passed in the cavity that the oxygen filter membrane stretches into mould overcoat and nut, and is connected with the mould overcoat.
Another kind of structure of the present invention is: the lower end of said filter bottle is provided with the end opening of flange; Be provided with screw thread below the end opening place flange; The bottle of threaded portion and the flange of end opening are formed the mould overcoat; Be provided with the lower cover that is threaded with it in the mould overcoat, the oxygen filter membrane is arranged between the flange of lower cover and end opening, and oxygen feeder is arranged on down and covers.
The further improvement of said lower cover is: its bottom has been provided with the pin that supports the bottle effect.
Improvement of the present invention also is: be provided with sealing ring between said oxygen filter membrane and the mould overcoat.
The improvement of said filter bottle is: the profile of said filter bottle is upper coarse and lower fine streamlined.
Owing to adopted above technical scheme, institute of the present invention acquisition of technology progress is:
The close-fitting setting of mould overcoat of the present invention and nut or lower cover; With oxygen seal in the arc lower cavity that mould overcoat and nut or lower cover form; Make oxygen be evenly distributed in each position of oxygen filter membrane, when pressure is enough, pass through oxygen filter membrane adverse current in humidification fluid.The oxygen filter membrane adopts the politef filter membrane, and its aperture is less than 0.35 μ m, be ten thousand of hydrone/; More than 1,000 times of steam; Can effectively intercept humidification fluid,, the most important thing is to filter out the pathogenic microorganism that causes because of source of oxygen, operating process, patient's breath etc. when oxygen is passed through; Avoid cross infection, guaranteed patient's oxygen uptake safety; And the oxygen that the small aperture of teflon membrane filter will be passed through is divided into very little bubble; Increased the contact area of oxygen and humidification fluid; Integrated sheet of gas when having avoided the bottom to go out oxygen; Strengthen the humidifying effect, also avoided air pocket to meet the plosive of water generates, effectively reduced the noise in the oxygen uptake process.Being provided with of sealing ring is beneficial to the mould overcoat and is connected with the tight of nut or lower cover, prevents that oxygen is excessive, and humidification fluid gets in the cavity.The airflow design of bottle is convenient to the operator and is held, and its upper coarse and lower fine design forms than large space the top of bottle; Not only can avoid the excessive entering of humidification fluid patient nasal cavity to cause danger; Also help the oxygen bubbles diffusion, reduce the resistance of oxygen flow, make flow of oxygen unobstructed; The setting that covers pin down is visual appearance not only, but also is convenient to during oxygen uptake, intermittently place.
