Abstract
The invention discloses a safety self-destruction subassembly for a syringe needle, and relates to the technical field of medical treatment. A protecting sleeve is slidably arranged on the outer side of a needle inserting tube; a spring plate is arranged in the protecting sleeve; an annular slot is formed in the needle inserting tube; a conical lug boss is arranged below the annular slot; and the spring plate is clamped in the annular slot. By the safety self-destruction subassembly for the syringe needle, the syringe needle can be used effectively and can also be destructed safely. The safety self-destruction subassembly for the syringe needle is convenient and safe and is used rapidly; cross infection is avoided; and medical treatment and public health are facilitated.
Description
technical field:
The present invention relates to a kind of injection needle safety self-destruct assembly, belong to field of medical technology.
background technology:
patent name is proposed for " structure of safety intravenous injector " in patent announcement CN200620116145.9, it has safety device, only syringe needle can be accommodated in syringe by single action, the pinprick probability that too much operating process causes can be reduced, therefore the potential safety hazard of manual operation can be reduced, but still there is the probability be secondary use in using.
Traditional entry needle is only adopt the mode of sheath to protect, but it still has the probability be secondary use, and therefore can cause disease and propagation.
Traditional entry needle can not effectively use and obtain averaging out between protection, otherwise numerous and diverse with regard to structure, easily comes off, uses not easily.
Traditional entry needle uses inconvenience, needs special adhesive tape to paste, and requires higher to nurse.
summary of the invention:
For the problems referred to above, the technical problem to be solved in the present invention is to provide a kind of injection needle safety self-destruct assembly.
Safety self-destruct assembly of the present invention; it comprises transfusion catheter, entry needle syringe needle, contact pin pipe; the contact pin pipe that transfusion catheter is connected with Plug pin patch bay connects; slide and be provided with protective sleeve in the outside of described contact pin pipe; protective sleeve inside is provided with reed; contact pin pipe is provided with annular slot, and below annular slot, is provided with conical boss, be fastened in annular slot during described reed self-destruction.
As preferably, described reed has two and in the distribution of protective sleeve internal symmetry, reed and protective sleeve are integrated injection moldings, are hollow out body outside reed.
As preferably, described annular slot bottom land and cell wall at a right angle, in groove, upper lower wall is parallel to each other; Annular slot outside diameter is greater than the distance between reed.
As preferably: between described Plug pin patch bay and protective sleeve being can disengagement structure.
Beneficial effect of the present invention: balance can be obtained effectively using between safety self-destruct, convenient and safe, use rapidly, can not cross infection, be conducive to health care.

detailed description of the invention:
As shown in figs. 1-7; this detailed description of the invention is by the following technical solutions: it comprises transfusion catheter 1, entry needle syringe needle 6, contact pin pipe 7; transfusion catheter 1 is connected with entry needle syringe needle 6 by contact pin pipe 7; it is characterized in that: slide and be provided with protective sleeve 3 in the outside of described contact pin pipe 7; protective sleeve 3 inside is provided with reed; contact pin pipe 7 is provided with annular slot 11, and below annular slot 11, is provided with conical boss 12, be fastened in annular slot 11 during described reed self-destruction.
Wherein, described transfusion catheter 1 connecting contact pin seat 2, described Plug pin patch bay 2 comprises the snap close 8 of two convex shapees, snap close 8 can be inserted in lockhole 9, and lockhole 9 is positioned on protective sleeve 3, and snap close 8 is inserted in lockhole 9 and is locked, the outside jug 4 of described protective sleeve 3; Described reed has two and distributes at protective sleeve 3 internal symmetry; Namely at saving cost and complete on the basis of effective self-locking, symmetrically effectively self-locking can be realized; Described handle 4 comprises two and symmetrical around protective sleeve centrage; This place is also in order to stability under loading time fixing on human body and fixes firm; Described handle 4 is flat; The flat at this place is preferred structure, but it does not cause restriction to this concrete enforcement; Described Plug pin patch bay 2 comprises hand part and divides, and described hand part is divided decorative pattern, and described hand part is divided and pinched inwardly and snap close 8 can be separated with the lockhole be inserted in 9; Described entry needle syringe needle 6 outside is also overlapped and is had needle tube sheath 5, and needle tube sheath 5 is arranged on protective sleeve base 10, and described needle tube sheath 5 is cylindric structure.
Distance in this detailed description of the invention between two pieces of reeds is suitable with the annular slot bottom land circular diameter on contact pin pipe; when contact pin pipe is along protective sleeve inwall slide downward; taper platform can be pushed reed open and slide, until reed is stuck in annular slot, protective sleeve port has also sealed syringe needle simultaneously.
Snap close 8 and snap close 9 can go out of lock state by this detailed description of the invention; protective sleeve 3 can slide upward; in the process slided upward; spring block can be fitted together to into annular slot 11 thus protective sleeve 3 is covered entry needle syringe needle 6; and due to its locking not unlocking structure, therefore complete safety self-destruct.
More than show and describe ultimate principle of the present invention and principal character and advantage of the present invention.The technical staff of the industry should understand; the present invention is not restricted to the described embodiments; what describe in above-described embodiment and description just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.Application claims protection domain is defined by appending claims and equivalent thereof.
