Description

Band safe vein pin single use blood exchange transfusion set

Technical field

This utility model relates to single use medical apparatus and instruments, is specifically related to a kind of band safe vein pin single use blood exchange transfusion set.

Background technology

The single use blood exchange transfusion set used the most in a large number at present and sell remains band tradition intravenous needle, its structure is needle stand, flexible pipe, needle tubing and sheath composition, there is problems in that sheath determines abandoned after sealing off use, and after having infused, the process for syringe needle is put in medical waste sharp disposable container often.Pulling out after using in the period that syringe needle extremely puts into sharp disposable container, these are unprotected and are in exposed contaminated pinhead very likely puncturing operation personnel or the skin of surrounding people, and this stabbing also can cause bacteria infection；Simultaneously during reclaiming these Biohazard Wastes, sharp syringe needle can puncture refuse bag and cause being scattered of Biohazard Waste, processes to medical care or cleanup crew's collection and causes the biggest difficulty.In use, abandoning of sheath becomes a kind of custom；Even if not abandoning sheath, sheath volume is little, specifies according to hospital operation, in order to avoid the generation of pricking wound, does not allow both hands relatively to answer cap, just causes these problems to be difficult to solve just because of sheath with needle tubing or completely disengaging from of syringe needle.

Summary of the invention

The purpose of this utility model is: provides band safe vein pin single use blood exchange transfusion set, simple in construction, easily operates, use safety.

Technical solution of the present utility model is: this band safe vein pin single use blood exchange transfusion set include: draw point sheath, bottle stopper puncture steel needle, aerofluxus draw point, tubulature, calparine cap, dropping funnel lid, dropping funnel, blood filter, long duct, flow regulator, two pass joints and safe vein pin, bottle stopper puncture steel needle is connected with dropping funnel lid by tubulature, dropping funnel lid is sleeved on dropping funnel, blood filter is arranged in dropping funnel, the bottom liquid outlet of dropping funnel connects long duct one end, the other end of long duct connects two pass joints through flow regulator, safe vein pin is installed on two pass joints, it is monolithically fabricated blood exchange transfusion set；It is characterized in that: described safe vein pin includes that 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, and anti-acupuncture sheath is socketed on needle handle；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 playing 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, and slot width is 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 is equal to 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, it is ensured that blade is not stuck during the effect lower slider of certain scope of data sliding force.

Wherein, described anti-acupuncture sheath is working of plastics, plays the effective length length more than syringe needle of protective action.

This utility model have employed the anti-acupuncture overwrap designs without departing from needle handle, anti-acupuncture sheath is spacing with needle handle blade, hand-held anti-acupuncture sheath slides up and down on needle handle, decrease abandoning of sheath, very easily sheath is set in outside syringe needle again after making to be finished, prevent the syringe needle from exposing, it is to avoid injury and the cross infection to doctor.

Detailed description of the invention

For ease of understanding, referring to the drawings embodiment of the present utility model is described in further detail.

Such as Fig. 1, shown in 2, this blood exchange transfusion set includes draw point sheath 1, bottle stopper puncture steel needle 2, aerofluxus draw point 3, tubulature 4, calparine cap 5, dropping funnel lid 6, dropping funnel 7, blood filter 8, long duct 9, flow regulator 10, two pass joints 11 and safe vein pin 12, bottle stopper puncture steel needle 2 is connected with dropping funnel lid 6 by tubulature 4, blood filter 8 is arranged in dropping funnel 7, dropping funnel lid 6 is sleeved on dropping funnel 7, the bottom liquid outlet of dropping funnel 7 connects long duct 9 one end, the other end of long duct 9 connects two pass joints 11 through Cornu Caprae seu Ovis flow regulator 10, safe vein pin 12 is installed on two pass joints 11, it is monolithically fabricated blood exchange transfusion set；It is characterized in that: described safe intravenous infusion needle 12 includes that anti-acupuncture sheath A, syringe needle B, single leaf thorn handle C, small hose D, needle stand E, syringe needle B, single leaf thorn handle C, small hose D, needle stand E are linked in sequence by adhesive, and anti-acupuncture sheath A is socketed on single leaf thorn handle C；Described anti-acupuncture sheath A is the sleeve pipe of both ends open, the anti-internal diameter of acupuncture sheath A matches with the external diameter of small hose D, there is the symmetrical S-shaped inclined otch a playing the guiding role one end of anti-acupuncture sheath A, a line of rabbet joint b is in axial direction offered at angular cut A terminal location in the side of anti-acupuncture sheath A, and line of rabbet joint b width is in case acupuncture needle handle C vane thickness is with reference to being arranged to different width along the line.

As it is shown on figure 3, line of rabbet joint b is provided with inlet slot A1, stopper slot A2 and guide groove A4,

The half of the inlet slot A1 width vane thickness less than anti-acupuncture needle handle C, the stopper slot A2 width vane thickness equal to anti-acupuncture needle handle C, the guide groove A4 width vane thickness slightly larger than anti-acupuncture needle handle C, card neck A3 is set between stopper slot A2 and guide groove A4, card neck projected side wall A31 respectively with stopper slot A2 sidewall and guide groove A4 sidewall rounding off, it is ensured that blade is not stuck during the effect lower slider at certain scope of data sliding force.

Wherein, described anti-acupuncture sheath A is working of plastics, and it plays the effective length length more than syringe needle B of protective action.

During as it is shown in figure 1, anti-acupuncture sheath A and needle handle C is set with, first by bevel cuts a, needle handle C blade being imported inlet slot A1, deformed by the Elastic Sliding of line of rabbet joint b, needle handle blade enters hypomere stopper slot A2 under a stretching force, and is fixed by card neck A3.

As in figure 2 it is shown, before carrying out venipuncture, pinch needle handle C blade on the other hand, another hands pinches anti-acupuncture sheath A toward drop-down, the direction slided by Elastic Sliding deformation and the needle handle C control of line of rabbet joint b and position, be pulled to sheath A small hose D end, then carry out venipuncture；Venoclysis is complete pull out pin after, more on the other hand pinch needle handle C blade, another hands pinches anti-acupuncture sheath 1 toward pull-up, just can be again set in outside syringe needle by sheath A, as shown in Figure 1.

Above-mentioned being intended for illustrates that the technical solution of the utility model is used, and be not limitation of the utility model, those skilled in the art, in the case of without departing from the spirit and scope of utility model, can also make a variety of changes and modification, the technical scheme of all equivalents falls within category of the present utility model.
