Description
Technical field
The present invention relates to health-care hospital equipment technical field, filling inhalator jar is medical under more particularly to a kind of lid
The method of oxygen.
Background technique
Oxygen is the big element that human body carries out metabolism and sustains life, and respiratory oxygen is converted into human body by alveolar exchange
Interior available oxygen is referred to as blood oxygen, takes blood oxygen from blood and conveys the nutriment energy to whole body, and the conveying capacity of blood oxygen and heart,
Brain working condition is closely related.For example, cardiac pumping ability is stronger, the content of blood oxygen is just better, the blood transfusion of heart coronary arteries
Ability is then stronger, and blood oxygen be transported to heart and brain whole body concentration it is higher, the operation conditions of human body vitals is better.
With the enhancing of people's self health consciousness, it is patient that oxygen, that is, commodity oxygen, which is no longer medical department already in clinic,
" patent " used, outdoor sports, tourism, mountain-climbing, archaeology, driver, sportsman, pregnant woman, operative doctor, the middle-aged and the old, painstaking effort
Pipe respiratory system patients with chronic diseases, medical rehabilitation personnel, white collar or even beauty place etc. be not rarely seen aerosol confession for office
Oxygen tank（Habit claims " health-caring oxygen jar "）, especially have sale in places such as pharmacy, market, supermarkets in recent years.Currently on the market
Common aerosol supplies oxygen tank（It is disposable）, oxygen purity is between 92%-95%, and canning means, by two kinds, first is
Filling under vacuumizing cover, second is that cylinder compression is filling.Strictly speaking both methods cannot all reach national medical oxygen
Standard requirements.Especially second method, the material that the piston ring of compression cylinder uses is critically important, medical oxygen GMP（Good
Manufacturing Practice）Specification points out that the compression cylinder of medical oxygen is forbidden to use the piston ring of fluoroplastics material（Mesh
The material or blank of the non-fluorine plastic piston ring of preceding domestic market）, in this way, stringent should eliminate for institute.The first
Filling method under vacuumizing cover, since inhalator jar is small by negative pressure ability（Vacuum conference keeps inhalator jar deflated）, so inhalator jar
The air of kind cannot all be taken out, therefore the standard of medical oxygen is also not achieved at most 95% or so in oxygen purity（Medical oxygen
National standard is that oxygen purity is not less than 99.5%）.Based on the above reasons, under method lid of the present invention using the displacement of vacuum filling gas
Filling inhalator jar medical oxygen, just revolutionizes the defect of both the above method, and has complied fully with wanting for medical oxygen GMP
It asks.Therefore developing small in size, the light-weight and portable inhalator jar medical oxygen for meeting hygiene and health requirement has actively meaning
Justice.
Technical information relevant to inhalator jar medical oxygen can be seen in by not retrieving in disclosed Chinese patent literature.
Therefore, how to provide one kind can make gaseous state medical oxygen is purer, meet health and GMP standard requirements, without two
Under the lid of secondary pollution risk the problem of method those skilled in the art's urgent need to resolve of filling inhalator jar medical oxygen.
Summary of the invention
In view of this, the present invention provides one kind can make gaseous state medical oxygen is purer, meets hygienic and GMP standard to want
Ask, under the lid of risk without secondary pollution filling inhalator jar medical oxygen method.
To achieve the above object, the present invention provides the following technical solutions：
A kind of method of filling inhalator jar medical oxygen under lid, which is characterized in that comprise the following steps that：1, meeting outsourcing

Extraction valve（265）It is again switched off, replaces oxygen interface（264）It is again turned on inflation, the pure medical oxygen body of a low pressure is filled and adds
Taking out a gas is a replacement cycles, and cycle-index can be set, and range is at 0-5 times, after circulation terminates, oxygen interface
（264）Two inflation one-way control valves automatically open simultaneously, start to fill the medical oxygen gas of setting pressure（General setting aerosol
Static pressure is less than or equal to 0.8MPa in tank）, inhalator jar（23）Interior pressure is set by inflationtime, and the time is reached
（Reach setting pressure）Charge valve is closed, and upper cylinder resets, and valve deck is pressed in inhalator jar（23）On, the pumping for inhaling valve deck is true
Sky stops；Sealing cylinder（24）Start to act, by stomata on sealing cylinder（241）Air inlet, while sealing cylinder air holes（242）
Long gas shift exhaust, sealing cylinder piston（243）Downlink, sealing cylinder piston rod（243）Drive sealing shaft（245）Downwards, make
Seal claw（252）It opens, valve deck is tamping in inhalator jar（23）On, sealing cylinder after sealing（24）It automatically resets, head is certainly
Dynamic to lift reset, a working cycles terminate, and can show the quantity of filling inhalator jar medical oxygen on PCL touch screen automatically.
