Abstract

The utility model relates to a safe injector belongs to the medical instrument field, including the syringe needle, the syringe needle is fixed on the needle file, the needle file card is on the cassette, the needle file geomery is supporting with the geomery of cassette, the cassette passes through the spring to be fixed at the cylinder tip, tightly there is not the clearance between spring coil and the circle, the needle file passes through hose and cylinder intercommunication, needle file one side upwards all is equipped with the arch in axial and week, two protruding chiasma formation crosss are protruding, set up the cross -shaped groove who corresponds with the cross arch on the cassette, in the time of in the cassette is gone into to the needle file card, the cross is protruding to be cooperated with cross -shaped groove, set up the card strip of cross -section for arc on one side of the cylinder, the card strip is the major arc, card strip internal diameter is unanimous with the needle file external diameter, card strip length is greater than the total length of syringe needle and needle file, the syringe needle is integrative with the cylinder, avoid the cylinder tip to be polluted by the germ, can prevent the slight patient's misery that causes of trembling of injector's hand, hinder to medical personnel simultaneously.

Description

Safety injector

Technical field

The utility model relates to a kind of safety injector, belongs to medical instruments field.

Background technology

Cause viral cross-infection for fear of using antihygienic syringe, disposable syringe is at medical field quiltBe widely used, reuse in order to stop artificial recovery, people are provided with self-desttruction equipment on disposable syringe. CommonAlthough can preventing reusing of syringe to a certain extent, cause self-destroyed syringe viral intersection to disturb, syringeAfter use, make discarded syringe produce more problem in the process of collecting, transport, processing because draw point exposes, still haveMay stab medical personnel. Syringe normally thrusts fast patient skin in the time puncturing, and then completes injection process,In injection, if injector's hand slight jitter will cause patient's misery. Present syringe needle all separates with syringe, while taking-up from aseptic packaging, syringe end, unavoidably by airborne pathogen contamination, has increased the ill of patient to a certain extentRisk.

Utility model content

According to above deficiency of the prior art, the technical problems to be solved in the utility model is: a kind of safety injector is provided,Syringe needle and syringe one, avoid syringe end by pathogen contamination, can prevent patient's misery that injector's hand slight jitter causes,Hurt medical personnel simultaneously.

Safety injector described in the utility model, comprises syringe needle, and syringe needle is fixed on needle stand, pin base fastener on deck, needle standThe geomery of geomery and deck is supporting, and deck is fixed on syringe end by spring, between turn and circle, does not also tightly haveGap, needle stand is communicated with syringe by flexible pipe, and needle stand one side is equipped with projection on axial and circumferential, and two projections intersect to form tenFont projection arranges the cross groove corresponding with cross projection on deck, and in needle stand snaps in deck time, cross is protrudingRise and coordinate with cross groove, in syringe one side, the card article that cross section is circular arc is set, card article is major arc, card article internal diameter and needle standExternal diameter is consistent, and card article length is greater than the total length of syringe needle and needle stand.

Operation principle and process:

When work, by pin base fastener, on deck, cross projection coordinates with cross groove, can limit needle stand in deck onLower movement and left-right rotation, when injection, if doctor's hand slight jitter, the bending of spring can prevent that syringe needle is subcutaneous patientMobile, alleviate patient's misery, also tightly very close to each other between turn and circle, can there is not non-doctor's wish in syringe needle in the time of punctureMove axially, after having injected, syringe needle is taken out in deck, then bend and needle stand is snapped in to card article, card article length is greater thanThe total length of syringe needle and needle stand, syringe needle can be hidden in card article completely, avoids stabbing staff.

The beneficial effect that the utility model compared with prior art had is:

Safety injector described in the utility model, font projection coordinates with cross groove, can limit needle stand in deck onLower movement and left-right rotation, when injection, if doctor's hand slight jitter, the bending of spring can prevent that syringe needle is subcutaneous patientMobile, alleviate patient's misery, also tightly very close to each other between turn and circle, can there is not non-doctor's wish in syringe needle in the time of punctureMove axially, card article length is greater than the total length of syringe needle and needle stand, and syringe needle can be hidden in card article completely, avoids the work of stabbingPersonnel, syringe is connected by flexible pipe with needle stand, has reduced the pollution of germ.

Detailed description of the invention

Below in conjunction with accompanying drawing, embodiment of the present utility model is described further:

As depicted in figs. 1 and 2, safety injector described in the utility model, comprises syringe needle 1, and syringe needle 1 is fixed on needle stand 2Upper, needle stand 2 is stuck on deck 3, and the geomery of needle stand 2 geomeries and deck 3 is supporting, and deck 3 is solid by spring 5Fix on syringe 7 ends, also tightly very close to each other between spring 5 circles and circle, needle stand 2 is communicated with syringe 7 by flexible pipe 4, needle stand2 one sides are equipped with projection on axial and circumferential, and two projections intersect to form cross projection 8, on deck 3, arrange and crossThe cross groove 9 of projection 8 correspondences, snaps in deck 3 when interior at needle stand 2, and cross projection 8 coordinates with cross groove 9,In syringe 7 one sides, the card article 6 that cross section is circular arc is set, card article 6 is major arc, and card article 6 internal diameters are consistent with needle stand 2 external diameters,Card article 6 length are greater than the total length of syringe needle 1 and needle stand 2.

Operation principle and process:

When work, needle stand 2 is stuck on deck 3, cross projection 8 coordinates with cross groove 9, can limit needle stand 2In deck 3, move up and down and left-right rotation, when injection, if doctor's hand slight jitter, the bending of spring 5 can preventSyringe needle 1, in the subcutaneous movement of patient, alleviates patient's misery, also tightly very close to each other between spring 5 circles and circle, syringe needle 1 in the time of punctureCan there is not moving axially of non-doctor's wish, after having injected, by syringe needle 1 from the interior taking-up of deck 3, then bending and by pinSeat 2 snaps in card article 6, and card article 6 length are greater than the total length of syringe needle 1 and needle stand 2, and syringe needle 1 can be hidden in card article 6 completelyIn, avoid stabbing staff.
