Abstract
The utility model relates to a self-destructive type disposable injection medicine core. The self-destructive type disposable injection medicine core is composed of an injection nozzle (1), a medicine core bag (2) and a push rod (3). A boosting injector head (4) is arranged on the push rod (3), and a stop dog (5) is arranged on the boosting injector head (4). A cavity passageway (6) is arranged in the medicine core bag (2). The portion, away from an annular groove (7), inside a miniature conical cylinder (8) is in a concave state, a conical cavity (9) matched with the stop dog (5) is arranged in the miniature conical cylinder (8), and an injection hole (10) is formed in a conical end of the conical cavity (9). After the structure is adopted, by stretching a push rod assembly, the stop dog is separated from the boosting injector head, the stop dog is reserved in the conical cavity, and therefore the medicine core is prevented from being used again. Different types of liquid medicine can be conveniently and selectively used due to the structural design, the medicine injection position is away from the skin, and liquid medicine is injected into the skin.

This utility model relates to the consumptive material of needleless injector, refers more particularly to a kind of medicated core that is applicable to the self-destructed disposable injection of painless intradermal injection instrument.
Background technology
At present, pistol type needleless injector is used in human injection, the advantage of Needleless injection has been to eliminate the fear of the person of being injected to syringe needle, eliminated pain, can save half vaccine consumption, the multiple injection system of good absorption: Intradermal, subcutaneous, intramuscular, simultaneously easily, also can produce other problem, after completing disposable injection, need to carry out disinfection to each position of syringe, especially contact the injection head of human body or animal body, inconvenient medical personnel carry out the not injection of medicinal liquid of the same race, continuously with in different medicinal liquid processes, if some hospital or mechanism utilize injection showerhead to carry out secondary use again, cause alternately and infect, be unfavorable for health, in addition, the medicinal liquid of smaller dose adopts traditional injection showerhead accurately to inject and to regulate, produce have disposable, can prevent what secondary from utilizing, and the medicated core that can very accurately regulate liquid dose becomes the problem that we need urgent solution.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of secondary utilization, low dose of self-destructed disposable injection medicated core that also can accurately be expelled to Intradermal of scalable of preventing.
In order to solve the problems of the technologies described above, this utility model provides self-destructed disposable injection medicated core, and it is comprised of injection nozzle, medicated core capsule and push rod; Described injection nozzle is fixedly connected on medicated core capsule, and described push rod is provided with boosting injector head, and described boosting injector head is provided with retainer, retainer and the boosting injector head state that is movably connected; In medicated core capsule, be set to cavity lane, push-rod assembly and medicated core capsule are suitable; Described injection nozzle is comprised of annular groove and micro-conical shell, micro-conical shell departs from and in annular groove, is spill state, in described micro-conical shell, be provided with the conical cavity suitable with retainer, the cone end of conical cavity is injection orifice, the aperture of described injection orifice is 0.1-0.2 millimeter, and described cavity lane extended spot is connected with conical cavity.
Described injection nozzle, medicated core capsule and push rod are made by polysaccharide acid esters material, and the medicated core length that injection nozzle assembly, medicated core capsule and push-rod assembly combine is 4-6cm.
Compared with prior art, the utlity model has following advantage.
Described injection nozzle is comprised of annular groove and micro-conical shell, micro-conical shell departs from and in annular groove, is spill state, the distance of the face contacting with patient is just far away, when injection orifice liquid medicine injection, under gas pressure, the medicinal liquid distance of spraying is just in time injected at patient's Intradermal, thereby can be expelled to accurately required position.
Described boosting injector head is provided with retainer, described retainer is tapered needle shape, in described micro-conical shell, be provided with the conical cavity suitable with retainer, described conical cavity can hold retainer, push-rod assembly and medicated core capsule are suitable, when medicated core is installed on pistol type syringe, conical cavity internal adsorption has low dose of medicinal liquid, pull rob plate under pressure the thrust unit on syringe push-rod assembly is pushed in conical cavity to nozzle assembly fast, medicinal liquid is penetrated by injection orifice, retainer on push-rod assembly and boosting injector head are movably connected, after injection, stretching push-rod assembly, retainer and boosting injector head disconnect, retainer rests in conical cavity, thereby reach, prevent secondary application target, the design of this structure facilitates between different medicinal liquids and is used alternatingly.
The medicinal liquid holding in conical cavity is limited, and the aperture of injection orifice is 0.1-0.2 millimeter, thereby effectively controls the dosage of medicinal liquid, and adjustable dosage is 0.1-1.0ml or 0.02-0.3ml.
Described injection nozzle assembly, medicated core capsule and push-rod assembly are made by polysaccharide acid esters material, and the medicated core that this material is made is compared with PP material, and material is harder, easily takes out medicine, and pull is convenient.
Accompanying drawing explanation
Fig. 1 is the structural representation of this utility model medicated core.
Fig. 2 is the perspective view of this utility model medicated core.
The specific embodiment
Below in conjunction with drawings and Examples, this utility model is further illustrated.
As depicted in figs. 1 and 2, self-destructed disposable injection medicated core, it is comprised of injection nozzle 1, medicated core capsule 2 and push rod 3; Described injection nozzle 1 is fixedly connected on medicated core capsule 2, and described push rod 3 is provided with boosting injector head 4, and described boosting injector head 4 is provided with retainer 5, retainer 5 and boosting injector head 4 state that is movably connected; In medicated core capsule 2, be set to cavity lane 6, push-rod assembly 3 is suitable with medicated core capsule 2; Described injection nozzle 1 is comprised of annular groove 7 and micro-conical shell 8, micro-conical shell 8 departs from and in annular groove 7, is spill state, in described micro-conical shell 8, be provided with the conical cavity 9 suitable with retainer 5, the cone end of conical cavity 9 is injection orifice 10, the aperture of described injection orifice 10 is 0.1-0.2 millimeter, and described cavity lane 6 extended spots are connected with conical cavity 9.
Described injection nozzle 1, medicated core capsule 2 and push rod 3 are made by polysaccharide acid esters material.
The medicated core length that injection nozzle assembly 1, medicated core capsule 2 and push-rod assembly 3 combine is 4-6cm.
