Abstract
The utility model relates to an ally oneself with micropin inserting needle sleeve or frame more and ally oneself with syringe more. Inserting needle sleeve or the framves of allying oneself with more for integrate many needles with array geometry, can realize the injection of many needles. Ally oneself with the syringe more and can regard as the pre -installation syringe, be equipped with novel array micropin. All adopt independent flow channel, it has the inhomogeneous shortcoming of array micropin hypodermic to overcome. Under the condition of needs, the injection of many needles can improve the injection efficiency, reduces medical personnel's intensity of labour.
Description
Technical field
The present invention relates to medical treatment, medical and beauty treatment, biomedicine technical field, particularly relate to the injection of a kind of hollow microneedles, realize the device of multiple spot array injection.
Technical background
Transdermal administration refers to by skin surface administration, produces the administering mode of whole body or local therapeutic effects.Percutaneous dosing, has many advantages, as avoided the first pass effect of liver; Without digestive system, avoid the drug degradation that medicine causes because of various enzyme, easy to use.
Administration through skin, can utilize the physicochemical property of medicine through skin with by mechanical broken skin, medicine directly to be entered in body.In fact drug administration by injection is exactly the direct administering mode of mechanical penetration skin.In recent years along with the progress of manufacturing technology, there is the mode of micropin administration, be the administering mode that traditional preparation capable of permeating skin and injection are combined, both overcome Traditional transdermal administration medicine transmitance not enough, and overcome again the shortcoming of regular injection administration patient dependence deficiency.
Micropin administration is on skin, create micron-sized medicament transport passage, alleviates the pain of regular injection, has the advantage of transdermal administration simultaneously.Some injection of insulin just have employed the micropin of 31G, 32G at present.The multiple array hollow microneedles of bibliographical information, for clinical multi-point injection.
Chinese patent CN10237656B, CN102309797B, EP1852142A1 disclose array miniature injection needle head.Above three kinds of injection devices announced, are all liquid storages above array syringe needle, then inject at push rod or under other forms of pressure.But, because the thickness of human skin tissue structure in each injection point position at a certain position, organizational structure are not complete and homogeneous, when the injection device of above structure is when injecting, the injection entered by the most weak spot position of skin histology may be at most, can not realize giving same injection volume in each injection point position, array point position, unpredictable side effect may be caused thus.The Preliminary Animal Experiment result of carrying out with the said goods commercially available at present shows, injects with it rat and the 2-3 monthly age man pig close with human body skin, really observes each injection point position and is injected into the different phenomenon of dose in skin histology.
Summary of the invention
One, the technical problem solved
Know-why of the present invention is for adopting independent medicinal liquid inserting needle passage, and the resistance run into when simultaneously spininess is injected and the most difficult entry point in skin histology quite, can ensure that medicinal liquid is injected into each injection point equably.The technical problem utilizing this principle to solve be how in different injection site fast, no leakage, hypodynia, safely insulin or other medicinal liquids are injected perpendicularly in body, improve patient compliance, improve injection stability, avoiding because injecting the uneven unpredictable side effect caused, alleviating labor intensity when medical worker when needing multi-point injection clinically adopts single needle injection simultaneously.
