Description
Technical field
The present invention relates to medical apparatus technical field, in particular to a kind of low pressure needleless injector.
Background technique
Traditional syringe is a kind of injection system by stainless steel syringe needle by infusion of medicine human body, this injection system
Subcutaneous, the damage of musculature is easily caused, tumour, or even infection are generated, not only feeling of pain is strong, and patient is uncomfortable, and
And most of patients (especially infant) is made to generate fear.Syringe needle accident fracture accident easily occurs in injection process, and
A point is concentrated on by the high amount of drug that metal needle injects, medicament forms bulk in injection site, is unfavorable for absorbing.
The whole world will handle 16,000,000,000 syringe needles every year, and have sharp metal needle to add rubber piston, plastic material etc. more
Kind causes the very big pollution and the wasting of resources of environment to the mankind at being grouped together.
Summary of the invention
The purpose of the present invention is to provide a kind of low pressure needleless injectors, difficult with the medicament for solving traditional syringe injection
To absorb, and the problem for keeping patient pain strong.
In order to solve the above technical problems, the present invention provides a kind of low pressure needleless injectors, comprising:
The air source input end of filling gun, the filling gun is connected to by hose with pneumatic shuttle；
Injection head has been removably installed on the injection end connector of the filling gun.
Optionally, the low pressure needleless injector further includes the regulator being mounted on the pneumatic shuttle, the gas
Source input terminal is connected to by the hose with the regulator.
Optionally, the dispensing end of the filling gun includes gun barrel, pin hole bracket, hole nut and adapter nut；Wherein,
The pin hole bracket is located in the gun barrel, and through hole nut is fixed；The adapter nut rotation is fixed on
On the hole nut.
Optionally, the gun barrel side is equipped with aperture, to connect injection tube.
Optionally, the filling gun is additionally provided with dosage adjusting device, to adjust the dosage of injection.
Optionally, the pneumatic shuttle includes gas cylinder and air compressor.
In low pressure needleless injector provided by the invention, including filling gun, the air source input end of the filling gun pass through
Hose is connected to pneumatic shuttle；Injection head has been removably installed on the injection end connector of the filling gun.This practical new offer
Low pressure needleless injector so that medicament is accelerated to 200-300 meters of speed per second using compressed gas as power, and form one pole
Its small liquid flow readily penetrates through skin surface, spreads in soft tissue, increases absorption area, improves assimilation effect, needleless
Injection avoids syringe needle fracture in human body, and greatly reduces pain.
Detailed description of the invention
Fig. 1 is low pressure needleless injector structural schematic diagram provided by the invention；
Fig. 2 is the configuration schematic diagram of the dispensing end of filling gun.
Specific embodiment
It is further detailed to a kind of low pressure needleless injector work proposed by the present invention below in conjunction with the drawings and specific embodiments
Explanation.According to following explanation and claims, advantages and features of the invention will be become apparent from.It should be noted that attached drawing is adopted
With very simplified form and using non-accurate ratio, only to facilitate, lucidly aid in illustrating the embodiment of the present invention
Purpose.
Embodiment one
The present invention provides a kind of low pressure needleless injector, including filling gun 1, the air source input end 11 of the filling gun 1
It is connected to by hose 2 with pneumatic shuttle 3；Injection head 13 has been removably installed on 12 connector of dispensing end of the filling gun 1.
The pneumatic shuttle 3 includes gas cylinder and air compressor.
Further, the low pressure needleless injector further includes the regulator 4 being mounted on the pneumatic shuttle 3, institute
Air source input end 11 is stated to be connected to by the hose 2 with the regulator 4.The regulator 4 is for adjusting the air pressure
The air pressure of device 3.
Specifically, referring to Fig. 2, the configuration schematic diagram of the dispensing end 12 for the filling gun 1.The filling gun 1
Dispensing end 12 include gun barrel 121, pin hole bracket 122, hole nut 123 and adapter nut 124；Wherein, the pin hole bracket
122 are located in the gun barrel 121, and through hole nut 123 is fixed；The rotation of adapter nut 124 is fixed on the hole spiral shell
On mother 123.Specifically, 121 side of gun barrel is equipped with aperture, to connect injection tube.The filling gun 1 is additionally provided with dosage tune
Regulating device 14, to adjust the dosage of injection.
The low pressure needleless injector of this practical new offer makes medicament accelerate to 200-300 per second using compressed gas as power
The speed of rice, and one extremely small liquid flow is formed, skin surface is readily penetrated through, is spread in soft tissue, increases and absorbs
Area improves assimilation effect；And pressure size can be controlled by regulator, and arbitrarily change injection pressure, it can be accurately
Medicament is reached into target site.Needleless injection avoids syringe needle fracture in human body, and greatly reduces pain.
Foregoing description is only the description to present pre-ferred embodiments, not to any restriction of the scope of the invention, this hair
Any change, the modification that the those of ordinary skill in bright field does according to the disclosure above content, belong to the protection of claims
Range.
