Description
Technical field
Of the present inventionly relate to medical apparatus field, particularly a kind of dosage or the adjustable needleless injector of injection depth.
Background technology
Needleless injection administration is a kind of Novel medicine feeding technology without puncture needle, and the potential energy of spring or gases at high pressure is the kinetic energy of medicine by it, makes medicine transdermal until parts such as Intradermal, subcutaneous or mucosa and play drug effect.This technology is specially adapted to the huge medicine of most of market share, as insulin, hepatitis B vaccine, influenza vaccines, AIDS vaccine, lignocaine etc.
Needleless injection have needleless, painless, without cross infection, portable, micro-, efficient, the feature such as safety, low cost, the patient being particularly suitable for probably pin sense, the child suffering from daily disease and the patient needing long-term automedication to treat, as chronic hepatitis, diabetes, tumor string person etc.In addition the diseases prevention and treatment under the medical support of vital emergent event, large-scale conventional prophylactic immunization and field work condition can also be used for.
A kind of spring needleless injector is had in needleless injector, have volume little, easy to operate, do not need professional training, advantage applied widely, but in use there are the following problems: be expelled to the position that some teleneuron is concentrated, inevitably cause mild pain, the dosage of single injection is little, when needs large bolus injection, need repeatedly repetitive operation be carried out, add the complexity of operation, for different injection objects and injected dose, injection depth is uncontrollable.
Summary of the invention
The present invention is directed to prior art Problems existing, provide a kind of dosage and the adjustable needleless injector of injection depth, so that the requirement of different liquid medicine injection dose and injection depth.
The object of the present invention is achieved like this, the needleless injector that a kind of dosage is adjustable, comprise injection member and compression member, described injection member comprises ampoule bottle and push rod, push rod front end is provided with the piston coordinated with ampoule bottle inwall, described ampoule bottle front end is provided with injection micropore, described compression member comprises the housing be connected with ampoule bottle, be provided with in described housing and store power spring, the described power of storing spring at front end is provided with the power that the stores block for pushing up pressure push rod, described in store power spring and regulate accumulation of energy size by bolt adjustment member.
Needleless injector of the present invention, pushes up pressure and stores power block after energy-storaging spring compress energy storage, store power block pushing tow push rod, and the medicinal liquid that push rod is promoted in ampoule bottle by piston realizes Needleless injection from spray-hole ejection.In using, according to injected dose size and injection depth requirement, change initial energy-storage pressure by bolt adjustment member, thus change the size of release potential energy.When injected dose is less or require to be expelled to subcutaneous more shallow position, only need reduces to store potential energy, namely reduce the displacement of spring release potential energy, otherwise, increase energy-storage pressure, can store and discharge larger potential energy, make heavy dose of injecting liquid drug to subcutaneous darker position.Therefore bolt adjustment member of the present invention can realize the adjustable of different injection depth and dosage.
For realizing object of the present invention further, described bolt adjustment member comprises adjusting bolt, the nut thread that described adjusting bolt and is fixed in housing is connected, the screw rod external part that described adjusting bolt stretches out nut has been threaded mobile block, described mobile block and energy-storaging spring squeeze flow, the outer end that described adjusting bolt stretches out housing is provided with the knob being convenient to turn.In this structure, nut and housing are fixed, turn bolt, and screw rod can be made to drive mobile block to move axially, thus the decrement of change spring is to change the storage potential energy of spring.
Accompanying drawing explanation
Fig. 1 is the adjustable needleless injector structural representation of a kind of dosage of the present invention.
Wherein, 1 ampoule bottle; 2 push rods; 3 housings; 4 energy-storaging springs; 5 move block; 6 nuts; 7 adjusting bolts; 8 knobs.
Detailed description of the invention
Be illustrated in figure 1 the needleless injector that dosage of the present invention is adjustable, comprise injection member and compression member, injection member comprises ampoule bottle 1 and push rod 2, push rod 2 front end is provided with the piston coordinated with ampoule bottle inwall, ampoule bottle 1 front end is provided with injection micropore, and compression member comprises the housing 3 be connected with ampoule bottle 1, is provided with and stores power spring 4 in housing 3, storing power spring 4 front end to be provided with for pushing up the power that the stores block of pressing push rod, storing power spring 4 and regulating accumulation of energy size by bolt adjustment member; Bolt adjustment member comprises adjusting bolt 8, the nut 6 that adjusting bolt 8 and is fixed in housing 3 is threaded, the screw rod external part that adjusting bolt 8 stretches out nut 6 has been threaded mobile block 5, mobile block 5 and energy-storaging spring 4 squeeze flow, the outer end that adjusting bolt 7 stretches out housing 3 is provided with the knob 8 being convenient to turn.
Needleless injector of the present invention, pushes up pressure after energy-storaging spring 4 compress energy storage and stores power block, stores power block pushing tow push rod 2, and the medicinal liquid that push rod 2 is promoted in ampoule bottle 1 by piston realizes Needleless injection from spray-hole ejection.In using, according to injected dose size and injection depth requirement, change initial energy-storage pressure by bolt adjustment member, thus change the size of release potential energy.When injected dose is less or require to be expelled to subcutaneous more shallow position, only need reduces to store potential energy, namely reduce the displacement of spring release potential energy, otherwise, increase energy-storage pressure, can store and discharge larger potential energy, make heavy dose of injecting liquid drug to subcutaneous darker position.Therefore bolt adjustment member of the present invention can realize the adjustable of different injection depth and dosage.
The present invention is not limited to above-described embodiment; every on the basis of technical scheme disclosed by the invention; those skilled in the art is according to disclosed technology contents; do not need performing creative labour just can make some to some technical characteristics wherein to replace and distortion, these are replaced and are out of shape all in the scope of protection of the invention.
