The purpose of this utility model is achieved through the following technical solutions: a kind of self-destructing type transfusion syringe easy to use, it comprises needle stand, shank, flexible pipe, needle guard, syringe needle and slip sheath, needle stand and shank link together by described flexible pipe, described needle stand is a funnel type needle stand, the two side of needle stand is provided with arc ear, be front with the needle point direction of syringe needle, described shank front end is connected with the rear end of syringe needle, described needle guard is enclosed within syringe needle, the rear end of shank is provided with one and pulls out pin hands handle, the front end of pulling out pin handle is provided with a pair buckle plug, described slip sheath is enclosed within shank, a clamping groove is offered in the rear end of slip sheath, the front end of buckle plug is positioned at clamping groove, described slip sheath is provided with the needle handle be fixed on skin, the upper surface of described needle handle is provided with multiple salient point be interspersed.
Described shank front end is provided with annular groove, on the sidewall of described slip sheath, symmetry offers square groove, elastic spacing fixture block is provided with in square groove, described elastic spacing fixture block rear end is provided with the spacing preiection coordinated with annular groove, and the distance between the spacing preiection of two symmetries is between shank diameter and annular groove diameter.
Described needle handle is the one in biplane needle handle or single-blade needle handle.
This utility model has the following advantages: transfusion needle of the present utility model, and needle stand is provided with arc ear, needle stand can be opened and tighten more time saving and energy saving, can rob valuable rescue time for patient; Needle handle is provided with salient point, and salient point can increase contact area, syringe needle not easily being skidded when plugging, ensure that the safety that syringe needle punctures; Plug handle adopts buckle to be connected with slip sheath, makes plug handle and can realize fast, easily between slip sheath being connected and departing from; Syringe needle is provided with annular groove, slip sheath is provided with elastic spacing fixture block and spacing preiection, after having infused, spacing preiection is clamping ring connected in star under the effect of elastic spacing fixture block, thus syringe needle cannot be moved forward and backward, transfusion needle is made to realize self-destruction, prevent the secondary of transfusion needle to use, avoid cross infection, syringe needle enters in slip cap simultaneously, ensure that the safety of process medical waste, prevent medical waste to the pollution of environment.

Detailed description of the invention
Be further described this utility model below in conjunction with accompanying drawing, protection domain of the present utility model is not limited to the following stated:
As Fig. 1, shown in Fig. 2 and Fig. 3, a kind of self-destructing type transfusion syringe easy to use, it comprises needle stand 1, shank 2, flexible pipe 3, needle guard 4, syringe needle 5 and slip sheath 6, needle stand 1 and shank 2 link together by described flexible pipe 3, described needle stand 1 is a funnel type needle stand, the two side of needle stand 1 is provided with arc ear 7, when operator operate, hand-held arc ear 7, thus make the hand-held convenience of operator, thus make needle stand 1 can realize fast, open easily and tighten, make needle stand open with tighten more time saving and energy saving, be front with the needle point direction of syringe needle 5, described shank 2 front end is connected with the rear end of syringe needle 5, as shown in Figure 3, described needle guard 4 is enclosed within syringe needle 5, the rear end of shank 2 is provided with one and pulls out pin handle 201, the front end of pulling out pin handle 201 is provided with a pair buckle plug 202, described slip sheath 6 is enclosed within shank 2, a clamping groove 8 is offered in the rear end of slip sheath 6, the front end of buckle plug 202 is positioned at clamping groove 8, described slip sheath 6 is provided with the needle handle 9 be fixed on skin, the upper surface of described needle handle 9 is provided with multiple salient point 10 be interspersed, salient point 10 adds the contact area of needle handle 9 and operator, thus add frictional force, make operator when pulling out pin or contact pin, not easily there is skidding, thus avoid syringe needle 5 and insert partially and the phenomenon of wrong plug, reduce the generation of malpractice, ensure that the safety of doctors and patients.
In the present embodiment, as Fig. 2, shown in Fig. 4 and Fig. 5, described shank 2 front end is provided with annular groove 203, on the sidewall of described slip sheath 6, symmetry offers square groove 12, level 90 ° of angles are become between square groove 12 with buckle plug 202, elastic spacing fixture block 11 is provided with in square groove 12, described elastic spacing fixture block 11 rear end is provided with the spacing preiection 13 coordinated with annular groove 203, distance between the spacing preiection 13 of two symmetries is between shank 2 diameter and annular groove 203 diameter, when buckle plug 202 is positioned at clamping groove 8, shank 2 clamped by spacing fixture block 11, thus make shank 2 cannot deflection, ensure that the stability of contact pin, after transfusion completes, pressing buckle plug 202, buckle plug 202 is made to depart from clamping groove 8, now the hand-held pin handle 201 that pulls out pulls backward, when annular groove 203 moves to spacing preiection 13 place, spacing preiection 13 is under the elastic reaction of elastic spacing fixture block 11, annular groove 203 is matched with spacing preiection 13, the displacement of restriction shank 2, thus make shank 2 to retreat again or to advance, this creates the terminal self-destroying function, prevent from reusing, avoid cross infection.
In the present embodiment, as the case may be, needle handle 9 can be set to the one in biplane needle handle or single-blade needle handle.
Work process of the present utility model is as follows: needle stand 1 is connected with transfusion device by hand-held arc ear 7, then takes off needle guard 4, hand-held needle handle 9, slowly advances syringe needle 5, is penetrated in patient vessel by syringe needle 5, thus infuse; After transfusion terminates, pressing buckle plug 202, the buckle pulled out between pin handle 201 with slip sheath 6 is connected remove, then pinch with finger and pull out the rear extreme direction twitch of pin handle 201 along slip sheath 6, syringe needle 2 is extracted out from blood vessel, and until annular groove 203 moves to spacing preiection 13 place of slip sheath 6, thus shank 2 is clamped under the effect of elastic spacing fixture block 11 and spacing preiection 13, now, slip sheath 6 protects syringe needle, realizes self-destroying function.
