Technical field
The present invention relates to medical instruments field more particularly to a kind of disposable combinations for medical oxygen inhalator
Humidification bottle system.
Background technique
Medical oxygen inhalator (hereinafter referred to as inhalator) is a kind of basic oxygen supply dress commonly used in medical institutions
It sets, carries out first aid oxygen supply and comfortable oxygen therapy by providing humidifying oxygen to patient.Inhalator is mainly by the stream of adjustable oxygen flow
Meter and equipped with humidifying liquid humidification bottle two large divisions composition.Flowmeter can be float type oxygen flow meter, be also possible to
Digital oxygen flow meter.The automatic pressure pressure relief device of mandatory carriage required by inhalator may be mounted on flowmeter,
It may be mounted on humidification bottle.
Medical oxygen (the either standby medical oxygen of liquid oxygen or absorption type system with molecular sieve for preparing) due to the reason of preparation process,
Contained humidity is only 10% or so, is not able to satisfy human body respiration physiological requirement, should not directly provide patient's use, it is necessary to will be medical
Oxygen is physically mixed in humidification bottle with humidifying liquid, and being formed to contain becomes wet compared with the aerosol particles of juicy
Change oxygen, enter patients with respiratory tract in the form of humidifying oxygen, avoid stimulation of the dry oxygen to respiratory mucosa, increases
The compliance of patient's oxygen uptake improves the comfort level of oxygen therapy effect and Case treatment.
It is normally carried out oxygen humidification to meet inhalator, needs to be packed into sterile water in humidification bottle as humidification fluid, to humidifying
The operation of addition humidification fluid is usually to be carried out by the bed of hospital inpatient area or in therapeutic room by nurse in bottle, the large intestine in air of the sickroom
The non-fermented pathogenic bacteria such as bacillus, salmonella, golden staphylococci, Pseudomonas aeruginosa and mould, or because air of the sickroom disinfection is insufficient,
Or because the humidification fluid of injection itself carries disease germs, or because humidification bottle disinfection is lack of standardization, germ will enter humidifying with air or humidification fluid
Bottle, is quickly bred in the humidification bottle of oxygen-enriched environment, becomes cross-infection source, and patient sucks the humidifying infected by germ
After oxygen, respiratory tract infection is easily caused, aggravates sufferer.
In China's Hospital Infection case, respiratory tract infection account for the first (bibliography: .164 hospitals of Zhang Fengqin
Lower Respiratory Tract Infection, Chinese Journal of Nosocomiology [J], 1996,6 (1): 30-31), wherein because of humidification fluid, medical device
Etc. therapeutic devices infection be cause pulmonary complication very important factor (bibliography: Lu Si Chinese medicine oxygen humidifying liquid and pass
The comparison of system oxygen humidifying liquid clinical application, occupation and key health magazine [J], 2003,19 (5): 112-113).Research shows that: oxygen
The pollution rate of gas humidification fluid is up to (60~80) %, and bacterial content can be greater than every milliliter 2 × 104A, pathogenic bacteria recall rate is up to
20%(bibliography: the Bacteriological Investigation and sterilization method [J] of Wang Shujun oxygen humidification bottle, Chinese Journal of Nursing, 1994,2
(1): 12).
The main reason for leading to germ contamination do not regularly replaced with humidification fluid, humidification bottle disinfection is not thorough etc. because being known as
Close (bibliography: the management method [J] of Zhang Chunxian, Wang Xijun, Zhang Jingping oxygen humidifying liquid, Chinese Journal of Nursing, 2001,36
(7): 542).
According to " hospital infection management specification " and " disinfection technology standard " that national health functional management department formulates, medical treatment
Mechanism executes " people one disinfection " to the humidification bottle that inhalator uses, and humidification fluid was by replacement one in aseptic technique 24 hours
Secondary, the Carriage of strict control humidification bottle and humidification fluid, the generation for reducing medical cross infection in oxygen therapy patient institute are beneficial
In reduction medical treatment cost, mitigate patient economy burden, shortening hospital stays, it has also become hospital infection management person and nursing staff get over
Come the problem of more concern.
In order to prevent medical cross infection in institute caused by humidification bottle, hospital generallys use the humidification bottle of reuse
Recycle after three kinds of sterilization method processing below: (1) medicining liquid dipping sterilizes, and the immersion treatment time is long, and low efficiency is wet after disinfection
It is dry inconvenient with keeping to change bottle.(2) ethylene oxide sterilizing is carried out disinfection using sterilizing chambers special costly, disinfection
Certain residue is had in bottle afterwards, water in bottle dirt is difficult to thoroughly remove, and influences to reuse.(3) high pressure sterilization, it is necessary in
Unified disinfection after entreating supply room to collect, long flow path, at high cost, the humidification bottle high molecular material intensity losses after disinfection make
With security risk, and the humidification bottle sterile keeping effect phase is still shorter.
Exactly because the disinfection for reusing humidification bottle is inconvenient, the disposable humidification bottle of prepackage humidifying liquid meet the tendency of and
It is raw.However in currently marketed disposable humidification bottle, many technical deficiencies are still remained:
(1) chemical glue sealing cup lid is used, has Environmental Safety hidden danger.The cup body and cup lid composition of Shooting Technique production are primary
Property use humidification bottle, reuse in order to prevent, after filling humidification fluid, built-in tracheae and other attachmentes, in addition to by cup body and cup
Lid is threadedly coupled outside fixed, also needs to solidify using glue adhering and sealing.Not only work efficiency is low, at high cost, but also the glue of chemical classes
Water is unfavorable for environmental protection and the safe handling of patient.

The aseptic result for changing liquid, discloses a solution, is carried out by the way that PET anodized aluminium sealed membrane is arranged in humidification bottle bottle mouth position
Sealing, solves the deficiency of above-mentioned technology.But during having ignored filling humidification fluid, into the air in bottle to the shadow of humidification fluid
It rings.After the air that carries disease germs enters humidification bottle, still pollution can be generated to humidification fluid in Storage period.Therefore, humidification bottle is pre- filling wet
Radiation sterilization must also be used after changing liquid, not only costly increase product cost, also adds the difficulty of quality control.
(3) most of disposable humidification bottles are inlet suction port, air outlet adapter and cup lid using injection molding, connection port
It is sealed with sealing shroud, because of the influence of carrying or storage condition in transportational process, the sealing performance of sealing shroud is deteriorated or falls off, and leads
Pathogenic bacteria enter in bottle from connection port, when have an impact humidification fluid quality accident occur.The entitled oxygen humidification bottle of Chinese patent
The solution of (application No. is 201010615897.0), although problems can be solved preferably, structure is complicated, materials compared with
When more, installation fee, it is at high cost, product lacks the market competitiveness.
