The utility model discloses a do not break away from the needle handle prevent acupuncture sheath design, prevent that the acupuncture sheath uses the needle handle blade for spacing, handheldly prevent that the acupuncture sheath slides about going on on the needle handle, reduced abandoning of sheath, very convenient overlapping the sheath is again established outside the syringe needle after the messenger uses up, prevents that the syringe needle from exposing.
Description
Technical field
This utility model relates to single use medical apparatus and instruments, is specifically related to a kind of single use safe intravenous infusion needle.
Background technology
Use in a large number on the market at present and sell remain traditional single use venoclysis needle, its structure is needle stand, flexible pipe, needle tubing and sheath composition, there is following problem: sheath determines abandoned after opening uses, and after having infused, the process for syringe needle is dropped in medical waste sharp disposable container often.Pull out syringe needle after using to dropping in during sharp disposable container, these are not protected and are in the skin of exposed contaminated pinhead very likely puncturing operation personnel or surrounding people, and this stabbing also can cause bacteria infection; Simultaneously in the process reclaiming these Biohazard Wastes, sharp syringe needle can puncture refuse bag and cause being scattered of Biohazard Waste, collects process cause very large difficulty to medical care or cleanup crew.In use, abandoning of sheath becomes a kind of custom; Even if do not abandon sheath, sheath volume is little, according to hospital operation regulation, in order to avoid the generation of pricking wound, does not allow both hands cap relatively again, and the disengaging completely just because of sheath and needle tubing or syringe needle just causes these problems to be difficult to solve.
Summary of the invention
The purpose of this utility model is: provide a kind of single use safe intravenous infusion needle, and structure is simple, easy to operate, safety and environmental protection.
Technical solution of the present utility model is: this safe intravenous infusion needle comprises syringe needle, single leaf thorn handle, small hose, needle stand and anti-acupuncture sheath, syringe needle, single leaf thorn handle, small hose, needle stand are linked in sequence by adhesive, anti-acupuncture sheath is socketed on needle handle, overall formation safe intravenous infusion needle; It is characterized in that: described anti-acupuncture sheath is the sleeve pipe of both ends open, the anti-internal diameter of acupuncture sheath matches with the external diameter of small hose, there is the symmetrical S-shaped inclined otch play the guiding role one end of anti-acupuncture sheath, a line of rabbet joint is in axial direction offered at angular cut terminal location in the side of anti-acupuncture sheath, slot width with single leaf thorn handle vane thickness for reference to being arranged to different width along the line.
Wherein, described Cao seams inlet slot, stopper slot and guide groove, inlet slot width is less than the half of the vane thickness of anti-acupuncture sheath, spacing groove width equals the vane thickness of anti-acupuncture sheath, channel widths is slightly larger than the vane thickness of anti-acupuncture sheath, card neck is set between stopper slot and guide groove, card neck projected side wall face respectively with stopper slot sidewall and guide groove sidewall rounding off, ensure that blade carries out not being stuck in the process slided up and down.
Wherein, described anti-acupuncture sheath is elastic plastic member, and the effective length that anti-acupuncture sheath plays protective action is greater than the length of syringe needle.
This utility model have employed the anti-acupuncture overwrap designs not departing from needle handle, anti-acupuncture sheath is spacing with needle handle blade, and hand-held anti-acupuncture sheath slides up and down on needle handle, decreases abandoning of sheath, very easily sheath is set in outside syringe needle again after using, prevents syringe needle from exposing.
Accompanying drawing explanation
Fig. 1 is that this utility model is not when using or use the schematic diagram of rear defence acupuncture sheath pull-out protection.
The schematic diagram of anti-acupuncture sheath retraction when Fig. 2 is this utility model use.
Fig. 3 is the schematic diagram of anti-acupuncture sheath.
In figure: 1 anti-acupuncture sheath, 2 syringe needles, 3 single leaf thorn handles, 4 small hoses, 5 needle stands, A angular cut, the B line of rabbet joint, 11 inlet slot 11,12 stopper slots, 13 card necks, 14 guide grooves, 131 is protruding.
Detailed description of the invention
For ease of understanding, referring to accompanying drawing, embodiment of the present utility model is described in further detail.
As shown in Figure 1, 2, this safe intravenous infusion needle comprises anti-acupuncture sheath 1, syringe needle 2, single leaf thorn handle 3, small hose 4, needle stand 5, syringe needle 2, single leaf thorn handle 3, small hose 4, needle stand 5 are linked in sequence by adhesive, and anti-acupuncture sheath 1 is socketed on single leaf thorn handle 3; Described anti-acupuncture sheath 1 is the sleeve pipe of both ends open, the internal diameter of anti-acupuncture sheath 1 matches with the external diameter of small hose 4, there is the symmetrical S-shaped inclined otch A play the guiding role one end of anti-acupuncture sheath 1, a line of rabbet joint B is in axial direction offered at angular cut A terminal location in the side of anti-acupuncture sheath 1, and line of rabbet joint B width is in case acupuncture needle handle 3 vane thickness is with reference to being arranged to different width along the line.
As shown in Figure 3, line of rabbet joint B is provided with inlet slot 11, stopper slot 12 and guide groove 14,
Inlet slot 11 width is less than the half of the vane thickness of anti-acupuncture needle handle 3, stopper slot 12 width equals the vane thickness of anti-acupuncture needle handle 3, guide groove 14 width is slightly larger than the vane thickness of anti-acupuncture needle handle 3, card neck 13 is set between stopper slot 12 and guide groove 14, card neck projected side wall 131 respectively with stopper slot 12 sidewall and guide groove 14 sidewall rounding off, ensure blade slide process in be not stuck.
Wherein, described anti-acupuncture sheath (1) is elastic plastic member, and the effective length of anti-acupuncture sheath (1) protective action is greater than the length of syringe needle (2).
As shown in Figure 1, when anti-acupuncture sheath 1 is set with needle handle 3, first by bevel cuts A, needle handle 3 blade is imported inlet slot 11, by the elastic deformation of line of rabbet joint B, needle handle blade enters hypomere stopper slot 12 under a stretching force, and is fixed by card neck 13.
As shown in Figure 2, before carrying out venipuncture, pinch needle handle 3 blade on the other hand, another hands pinches anti-acupuncture sheath 1 toward drop-down, the direction of being slided by elastic deformation and needle handle 3 control of line of rabbet joint B and position, be pulled to small hose 4 end, then carry out venipuncture by sheath 1; Venoclysis is complete pull out pin after, more on the other hand pinch needle handle 3 blade, another hands pinches anti-acupuncture sheath 1 toward pull-up, just sheath 1 can be set in outside syringe needle again, as shown in Figure 1.
Above-mentioned only for the technical solution of the utility model is described, and be not limitation of the utility model, those skilled in the art, when not departing from the spirit and scope of utility model, can also make a variety of changes and modification, all equivalent technical schemes also belong to category of the present utility model.
