Description
Technical field
This utility model relates to a kind of percussive medical fluid injector.
Background technology
Dermatosis often needs topical medications, traditional method comprises injection in local topical or local skin lesion, but local topical medicine is difficult to through skin barrier, depth of interaction shallow, in skin lesion, injectable drug skewness and with pain in tissue, limits topical medications curative effect.Often adopt micropin technology to reach promotion Drug Percutaneous Absorption in recent years, improve the uniformity that medicine distributes in the tissue.Early stage micropin is solid construction, leaves even duct after piercing through skin, and medicine enters subcutaneous along duct, administering effect is undesirable.Now part new type microneedle adopts hollow-core construction, and form empty micropin syringe, medicine enters subcutaneous along micropin boring duct, but preparation cost is expensive, is not suitable for clinically using on a large scale.Percussopunctator is the traditional acupuncture utensil of China, the form prick skin barrier of thorn is kowtowed with parallel needles, kowtow the thorn degree of depth controlled, there is no pain, can be used for transdermal administration, but traditional percussopunctator is solid construction, administering effect is poor, also has a few patents (" percussopunctator of injectable medicinal liquid ", patent No. ZL00260869.3) to can be implemented in drug administration by injection while thorn kowtowed by percussopunctator, operational efficiency improve, but design loaded down with trivial details, Clinical practice is inconvenient.Also there is no a kind of very good transdermal administration utensil at present.
Utility model content
The purpose of this utility model is to provide a kind of percussive cartridge syringe based on improvement percussopunctator, to overcome the shortcoming that above-mentioned technology exists.
The described percussive cartridge syringe based on improvement percussopunctator, comprise handle, closed at both ends and the pedestal of hollow, impact bead, piston plate, injection window, central canal and the hollow needle array that is made up of hollow needle;
Described pedestal is connected with handle, the side of described piston plate is provided with projection, described base internal wall is provided with chute, described projection is embedded in described chute, piston plate periphery and base internal wall are tightly connected, the side of piston plate is for clashing into room, opposite side is drug storage chamber, one end of described central canal is connected with piston plate, the other end is through the end of described pedestal, described impact bead is arranged in described central canal, described pedestal is provided with injection window, be positioned at drug storage chamber place, the bottom of described pedestal is passed in one end of described hollow needle, be connected with described drug storage chamber.
It is stronger that this utility model compares traditional percussopunctator administration ability, compares micropin dosing techniques simple, with low cost, in clinical extensive popularization, can be applicable to the various dermatosiss needing topical, have high clinical value.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of piston plate and pedestal.
Detailed description of the invention
See Fig. 1 and Fig. 2, the described percussive cartridge syringe based on improvement percussopunctator of the present utility model, comprise handle 1, closed at both ends and the pedestal 2 of hollow, impact bead 4, piston plate 6, injection window 7, central canal 9 and the hollow needle array that is made up of hollow needle 8;
Described pedestal 2 is connected with handle 1, the side of described piston plate 6 is provided with protruding 601, described pedestal 2 inwall is provided with chute 201, described projection 601 is embedded in described chute 201, piston plate 6 periphery is connected with pedestal 2 inner wall sealing, the side of piston plate 6 is for clashing into room 3, opposite side is drug storage chamber 5, one end of described central canal 9 is connected with piston plate 6, the other end is through the end of described pedestal 2, described impact bead 4 is arranged in described central canal 9, described pedestal 2 is provided with injection window 7, be positioned at drug storage chamber 5 place, the bottom of described pedestal 2 is passed in one end of described hollow needle 8, be connected with described drug storage chamber 5,
Preferably, described pedestal 2 is cylindrical;
Preferably, the material of described injection window 7 is rubber;
Preferably, the material of described piston plate is mylar;
Preferably, described impact bead is solid metal ball;
The quantity of the hollow needle in described hollow needle array is 3 ~ 7.
This utility model uses like this:
By central canal 9 outwards pull-up, drug storage chamber 5 is injected through injection window 7 by needing the medicine of topical, then hand-held handle 1, aims at hollow needle array and needs the skin of topical to knock, and thrusts after skin stop a moment a little until hollow needle array, impact bead 4 is because of gravity and effect of inertia percussion piston plate 5, piston plate 5 moves down, and makes medicine pressurized in drug storage chamber 5, enters in skin through hollow needle array, repeated multiple timesly can knock, make medicine as far as possible many and enter equably in skin.
