Abstract
A kind of disposable syringe of separable pinhead sleeve, comprise syringe, syringe needle and pinhead sleeve, the inside, edge of the opening part of described pinhead sleeve is provided with projection, and described pinhead sleeve and syringe needle are connected together by projection, it is characterized in that: the bottom of described pinhead sleeve is fixed with rubber stopper; The opening part of described pinhead sleeve comprises upper cover and lower cover, and described upper cover is integral type with lower cover and structure is consistent; The bottom of described upper cover is thinner wall section, and the arranged outside of described thinner wall section fractures cut; The length of described upper cover is greater than distance when syringe needle and pinhead sleeve are connected together between needle point and rubber stopper.Operator before the use, pinhead sleeve edge is two-layer design, when pinhead sleeve is enclosed within syringe needle, syringe needle does not contact with rubber closure, after exhausting vim and vigour, the part at the edge of pinhead sleeve is separated, when covering pinhead sleeve, quick and precisely syringe needle can be inserted rubber closure, decrease and air time of contact.
Description
Technical field
The present invention relates to a kind of medical supplies, especially relate to a kind of disposable syringe of separable pinhead sleeve.
Background technology
In clinical nursing procedure, after operator exhausts vim and vigour to patient, immediately the inclined-plane of syringe needle need be inserted rubber closure rapidly, in order to avoid and air Contact Effect vim and vigour result.But when operating, as because of carelessness, it is in one's hands that syringe needle is easy to wear out or penetrate rubber closure thorn, causes pricking wound.Have the disease of the blood born such as hepatitis B, hepatitis C, syphilis, acquired immune deficiency syndrome (AIDS) as patient, being punctured rear operator also may be infected.Consequence is very serious, causes very large injury to operator.
In actual mechanical process, there is rubber closure to fill in bottom pinhead sleeve and prevent air from entering, but, this design is only applicable to take out arterial blood, need by syringe needle rubber closure isolate situation, phlebotomize or medicine time, do not need syringe needle to inject rubber closure, this pinhead sleeve cannot meet.Or needle design is become scalable form, but syringe needle is comparatively thin after all, and the design of scalable form is loaded down with trivial details, is unfavorable for large-scale production.
Summary of the invention
In order to overcome the deficiency in background technology, the invention discloses a kind of disposable syringe of separable pinhead sleeve.
In order to realize described goal of the invention, the present invention adopts following technical scheme:
A kind of disposable syringe of separable pinhead sleeve, comprise syringe, syringe needle and pinhead sleeve, the inside, edge of the opening part of described pinhead sleeve is provided with projection, and described pinhead sleeve and syringe needle are connected together by projection, it is characterized in that: the bottom of described pinhead sleeve is fixed with rubber stopper; The opening part of described pinhead sleeve comprises upper cover and lower cover, and described upper cover is integral type with lower cover and structure is consistent; The bottom of described upper cover is thinner wall section, and the arranged outside of described thinner wall section fractures cut; The length of described upper cover is greater than distance when syringe needle and pinhead sleeve are connected together between needle point and rubber stopper.
Upper cover described in the utility model and lower cover are split-type structural, and the connected mode between described upper cover and lower cover, for being threaded, is provided with sealing ring between described two-layer screw thread.
Syringe needle one end of syringe described in the utility model, is provided with support ring.
The external shape of support ring described in the utility model is circular, square or triangle.
Owing to have employed technique scheme, the present invention has following beneficial effect: operator before the use, pinhead sleeve edge is two-layer design, when pinhead sleeve is enclosed within syringe needle, syringe needle does not contact with rubber closure, after exhausting vim and vigour, the part at the edge of pinhead sleeve is separated, when covering pinhead sleeve, quick and precisely syringe needle can be inserted rubber closure, decrease and air time of contact.
In addition, this syringe, except blood drawing gas, also can using taking out medicine, when to phlebotomize etc., when not needing to carry out sealing-plug sealing to syringe needle, not being separated by pinhead sleeve.The design of support ring, after making syringe exhaust medicine or venous blood, time transient level is placed, syringe needle is unsettled, and not with other object contacts, better protection syringe needle is not contaminated.
Design of the present utility model makes operator avoid pricking wound, operates also easier.In addition, this utility model structure is simple, is easy to use quick, is applicable to large-scale production.
Accompanying drawing explanation
Fig. 1 is the structural representation of this utility model embodiment 1.
Fig. 2 is the structural representation of this utility model embodiment 1 pinhead sleeve.
Fig. 3 is the structural representation of this utility model embodiment 2.
In figure: 1, rubber stopper; 2, pinhead sleeve; 3, syringe needle; 4, lower cover; 5, thinner wall section; 6, protruding; 7, upper cover; 8, support ring; 9, syringe; 10, be threaded; 11, sealing ring.
Detailed description of the invention
By explanation the present invention that the following examples can be detailed, disclose object of the present invention and be intended to protect all technological improvements in the scope of the invention.
Embodiment one
A kind of disposable syringe of separable pinhead sleeve, comprise syringe 9, syringe needle 3 and pinhead sleeve 2, the inside, edge of the opening part of described pinhead sleeve 2 is provided with protruding 6, and described pinhead sleeve 2 and syringe needle 3 are connected together by projection, and the bottom of described pinhead sleeve 2 is fixed with rubber stopper 1; The opening part of described pinhead sleeve 2 comprises upper cover 7 and lower cover 4, and described upper cover 7 is integral type with lower cover 4 and structure is consistent; The bottom of described upper cover 7 is thinner wall section 5, and the arranged outside of described thinner wall section 5 fractures cut; The length of described upper cover 7 is greater than distance when syringe needle 3 and pinhead sleeve 2 are connected together between needle point and rubber stopper.In use, after exhausting blood, directly fracture in thinner wall section 5 part, be separated by upper cover 7 with lower cover 4, when pinhead sleeve 2 only covers syringe by lower cover 4, syringe needle 3 is just pricked in rubber stopper 1, prevents air from entering.Syringe needle one end of described syringe 9, is provided with support ring 8, and the external shape of described support ring 8 is circular, square or triangle.There is the support of support ring 8, when syringe exhausts horizontal positioned after blood, syringe needle can not have been made to be close to desktop, guard against cross infection.
Embodiment two
On the basis of embodiment one, described upper cover 7 and lower cover 4 are split-type structural, and the connected mode between described upper cover 7 and lower cover 4, for being threaded 10, is provided with sealing ring 11 between described two-layer screw thread.
Part not in the detailed description of the invention is prior art.
