Description
Technical field
The present invention relates to the consumptive material of needleless injector, refer more particularly to a kind of medicated core that is applicable to the self-destructed disposable injection of Painless Muscle Injection instrument.
Background technology
At present, the pistol type needleless injector is used in the 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 each position of syringe be carried out disinfection, 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 the 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.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of secondary utilization, low dose of self-destructed disposable injection medicated core that also can accurately be expelled to muscle of scalable of preventing.
In order to solve the problems of the technologies described above, the invention provides the self-destructed disposable injection medicated core of painless intradermal injection instrument, it is comprised of injection nozzle assembly, medicated core capsule and push-rod assembly.
Described injection nozzle assembly is fixedly connected on the medicated core capsule, described push-rod assembly is by push rod, support bar, O type circle and boosting injector head, described boosting injector head is provided with retainer, retainer and the boosting injector head state that is movably connected, described retainer is the tapered needle shape, and described conical cavity can hold retainer.
Be set to cavity lane in the medicated core capsule, the diameter of described cavity lane is consistent with the diameter of O type circle in push-rod assembly, and push-rod assembly and medicated core capsule are suitable.
Described injection nozzle assembly is comprised of annular groove and micro-conical shell, the height of the annular groove degree of depth and micro-conical shell is consistent, be provided with the conical cavity suitable with retainer in described micro-conical shell, the cone end of conical cavity is injection orifice, described cavity lane extended spot is connected with conical cavity, and the aperture of described injection orifice is the 0.1-0.2 millimeter.
Described O type circle is arranged between support bar and boosting injector head, and the length of described support bar and boosting injector head is consistent with the length of cavity lane.
The medicated core length that injection nozzle assembly, medicated core capsule and push-rod assembly combine is 3-5cm
Described injection nozzle assembly, medicated core capsule and push-rod assembly are made by polysaccharide acid esters material.
Compared with prior art, the present invention has the following advantages.
Described boosting injector head is provided with retainer, described retainer is the tapered needle shape, be provided with the conical cavity suitable with retainer in described micro-conical shell, described conical cavity can hold retainer, push-rod assembly and medicated core capsule are suitable, when medicated core is installed on the pistol type syringe, the 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, the stretching push-rod assembly, retainer and boosting injector head disconnect, retainer rests in conical cavity, prevent the secondary application target thereby reach, the design of this structure facilitates between different medicinal liquids and is used alternatingly.
The medicinal liquid held in conical cavity is limited, and the aperture of injection orifice is the 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 is comprised of annular groove and micro-conical shell, the height of the annular groove degree of depth and micro-conical shell is consistent, annular groove and micro-conical shell keeping parallelism, the distance of the face contacted with the patient is just nearer, when the injection orifice liquid medicine injection, under gas pressure, the medicinal liquid of injection distance just in time is injected at patient's intramuscular, thereby can be expelled to accurately required position.
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 the PP material, and material is harder, easily takes out medicine, and pull is convenient.
The accompanying drawing explanation
The structural representation that Fig. 1 is medicated core of the present invention.
The front view that Fig. 2 is medicated core of the present invention.
The axonometric chart that Fig. 3 is medicated core of the present invention.
The specific embodiment
Below in conjunction with drawings and Examples, the present invention is further described.
As Figure 1-3, the self-destructed disposable of painless intradermal injection instrument injection medicated core, it is comprised of injection nozzle assembly 1, medicated core capsule 2 and push-rod assembly 3; Described injection nozzle assembly 1 is fixedly connected on medicated core capsule 2;
Described push-rod assembly 3 is by push rod 5, support bar 6, O type circle 7 and boosting injector head 8, described boosting injector head 8 is provided with retainer 9, described retainer 9 is the tapered needle shape, described conical cavity 11 can hold retainer 9, retainer 9 and boosting injector head 8 state that is movably connected, described O type circle 7 is arranged between support bar 6 and boosting injector head 8, the length of described support bar 6 and boosting injector head 8 is consistent with the length of cavity lane 4, be set to cavity lane 4 in medicated core capsule 2, the diameter of described cavity lane 4 is consistent with the diameter of O type circle 7 in push-rod assembly 3, push-rod assembly 3 is suitable with medicated core capsule 2,
