Description
Technical field
The utility model belongs to medical instruments field, relates to a kind of doser, particularly relates to a kind of pneumatic doser.
Background technology
Needleless injector, it is simply that when carrying out drug injection not by syringe needle, uses high-pressure spray principle, makes liquid be formed
Thinner liquid stream, it is subcutaneous that moment penetrates skin arrival, and this method can terminate the epoch ached of having an injection.
Needleless syringe delivery device is particularly suitable for having the patient of probably pin sense, needs long-term automedication patient, children to suffer from
Person, vital emergent event (earthquake, big flood, popular, the struggle against terror of acute deadly infectious disease etc.) and outlying district, on a large scale open country
Protection guarantee under the conditions of outer operation etc..Additionally, diabetes are a kind of common Chronic Progressive diseases, according to the World Health Organization
Statistics, the whole world there are about 1.8 hundred million people and suffers from diabetes, it is predicted that within 2025, patient's number will rise to 300,000,000.At present, China's glycosuria
Patient is more than 100,000,000 people and annual in increasing trend, about increases diabetic more than 100 ten thousand person-times every year newly, uses insulin
It is the treatment means that diabetic is the most laborsaving, most effective, bad reaction is minimum.And diabetic's time of hospitalization is relative
Less, substantially by family numbers of patients insulin injection voluntarily outside institute, and injection of insulin is only, and the sub-fraction of Needleless injection should
With market, broader space should be on follow-up product.
Current needleless injector is mainly by external high-pressure air source, utilizes spraying high-pressure gas by powdery medicine particulate
Or microballoon accelerates to certain speed and drug microparticles penetrates skin outer layer is delivered to subcutaneous, muscle or mucosa, medicine exists
Specific tissue layers release, performance drug effect.But the needleless injector described in above-mentioned prior art carries inconvenience, and external height
Pressurized air source installs inconvenience, causes user to be intended to assemble when each use, is unfavorable for that the elderly operates.
Content of the invention
Solve the technical problem that: integrated with needleless injector in order to obtain a kind of high-pressure air source, and high-pressure air source and storage
Medicine medicine-feeder convenient disassembly, it is simple to the doser carrying, the utility model provides a kind of pneumatic doser.
Technical scheme: a kind of pneumatic doser, including manual handle and shell, is provided with transmission eccentric in described shell
Wheel, gas bullet room, connection column sleeve pipe and diffusion accelerating tube, wherein transmission eccentric wheel is connected with manual handle, and gas bullet indoor are provided with two
Carbonoxide gas bullet, and carbon dioxide gas bomb is connected with transmission eccentric wheel；It is provided with drug storage medicine-feeder, gas bullet in described connection column sleeve pipe
Pricker and silica gel valve therebetween；Described diffusion accelerating tube is located at drug storage medicine-feeder front end.
Preferably, shell is provided with slip lid snap close.
Preferably, described transmission eccentric wheel is connected with the Fastening tenon structure that manual handle uses draw pin and mortise to be integrated.
Preferably, described connection column sleeve pipe and diffusion accelerating tube spiral connect.
Preferably, described drug storage medicine-feeder outer surface is provided with transparent scale plate.
Beneficial effect: (1) described pneumatic means and delivery system are installed as one, easy to carry and readily accessible and group
Dress；(2) manual handle is connected with transmission eccentric wheel, can control the horizontal movement of gas bullet room, and in the effect of gas bullet pricker
Lower release gases at high pressure, by silica gel valve, carry adaptation medicine and enter in diffusion accelerating tube；(3) drug storage medicine-feeder outer surface sets
There is transparent scale plate, facilitate look at syringe amount to be injected, it is simple to user's Charge control.
