Description
Technical field
This utility model relates to a kind of painless shaping injection pin, specifically a kind of shaping injection special combination pin.
Background technology
In recent years, painless blunt pin injection beauty treatment with it easily and fast, seamless characteristic obtains numerous favor asking beautiful person, injection beauty treatment is referred to as " lunch beauty treatment " and very popular.Carry out the injection of hyaluronic acid before this with sharp pin, if Doctors' skill is not in place, slightly mistake just there will be blue or green even more serious complication of becoming silted up.And the appearance of blunt pin injection technique, the safety of its brilliance can avoid similar accident to occur just.Painless blunt needle injection, this drug delivery system can avoid syringe needle to the injury of human body, prevent the hemorrhage of Drug leakage and injection site, can carry out accurate administration in any degree of depth of skin (Intradermal or intramuscular) by high viscosity or containing the mixture of microgranule, permeable drug is to being difficult to the position injecting and can not use unguentum.At present, operate use blunt pin to inject time, after first adopting common sharp pin (hollow needle tubing, angle syringe needle) to carry out perforate on skin, re-use blunt pin and can enter into inside skin and inject.But with this sharp pin puncture, it has two shortcomings: 1, the syringe needle of sharp pin is in fact just as flat bayonet, the opening that skin " cutting " is in-line; And when inserting from this mouth immediately following the blunt pin of round end thereafter, the skin histology of in-line opening by the blunt pin extruding of round end or can be torn again, people is made to produce pain or secondary insult between Shun.2, when using the operation of common sharp pin puncture, because sharp pin is too short, thus also to use in addition a new syringe be connected on after serve as the handlebar of lengthening, better operate.Next common sharp pin is hollow needle bobbin head, and after hemorrhage to skin puncture, can be docked at syringe below and form pollution, after generally using, conventional needle and syringe will together be discarded, and due to discarding of syringe, causing use cost increases.Therefore a kind of shaping injection special combination pin is invented necessary.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, a kind of shaping injection special combination pin is provided, comprise sharp pin, sheath, blunt pin, needle stand and blunt needle shield, it is characterized in that: the central shaft of the lower connecting portion of connection handle is provided with a sharp pin, connecting portion is plugged in sheath together with sharp pin, and upper connecting portion is plugged in needle stand, and needle stand is plugged in blunt needle shield together with blunt pin.The interlude of described connection handle is cylindrical, and two ends connect lower connecting portion outside round platform and upper connecting portion respectively.Described sharp pin is solid needle tubing, and one end is plugged on the lower connecting portion central shaft of connection handle, and the other end is the prong head of rectangular pyramid shape.
The beneficial effects of the utility model are: 1, structure is simple, easy to use.2, adopt solid rectangular pyramid prong head to human body skin puncture, open a criss-cross mouth, be convenient to the blunt pin of follow-up round end inject from unimpeded the entering into inside skin of opening part, effectively prevent round end blunt pin when entering skin histology, make people produce pain or secondary insult between Shun.3, connecting portion and the needle stand that is plugged in together on sharp pin connection handle, blunt pin and blunt needle shield as the same sharp pin increasing handlebar, more convenient during operation, safe and sanitary.4, eliminate with the syringe additionally used of needs during sharp pin puncture operation, because this reducing the cost using material.

Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model will be further described.
As shown in Figure 1, a kind of shaping injection special combination pin, comprise sharp pin 2, sheath 6, blunt pin 9, needle stand 7 and blunt needle shield 8, it is characterized in that: the central shaft of the lower connecting portion 3 of connection handle 4 is provided with a sharp pin 2, connecting portion 3 is plugged in sheath 6 together with sharp pin 2, and upper connecting portion 5 is plugged in needle stand 7, and needle stand 7 is plugged in blunt needle shield 8 together with blunt pin 9.The interlude of described connection handle 4 is cylindrical, and two ends connect lower connecting portion 3 and the upper connecting portion 5 of truncated cone-shaped respectively.Described sharp pin 2 is solid needle tubing, and one end is plugged on lower connecting portion 3 central shaft of connection handle 4, and the other end is the prong head 1 of rectangular pyramid shape.
When using blunt pin to inject, first sheath 6 is sloughed, connection pattern as shown in Figure 2, the connection handle 4 be plugged in together, needle stand 7, blunt pin 9 and blunt needle shield 8, the sharp pin of handlebar is increased as same, this moment, pinch connection handle 4 and blunt needle shield 8 just can carry out puncture easily on human body skin with finger simultaneously, after human body skin being opened what a cross aperture, just from needle stand 7, extract the used connection handle of opening 4 and sharp pin 2, throw into refuse receptacle, (the sharp pin that opening is crossed, must discard after single use) and then slough blunt needle shield 8, blunt pin 9 is socketed on the injector by needle stand 7, finally indenting ball 10 is entered into inside skin histology from the cross-shaped aperture on human body skin and complete injection.
