Description
Technical field
The invention belongs to a kind of medical apparatus and instruments, specifically belong to a kind of safe intravenous infusion needle.
Background technology
Venous transfusion is a kind of Therapeutic Method of inputting a large amount of sterile solutions or medicine through vein, in order to ensure not infected by antibacterial in infusion process, and after not reclaimed by illegal businessman after using, secondary uses, cause the infection such as the virus such as hepatitis B and AIDS, health ministry regulation venoclysis needle must disposable use.Simultaneously in order to guard against medical personnel to be pricked the hand and cause unexpected injury to be infected by sharp instrument in the intravenous infusion syringe process of processing after using, require the processing of unmaking without exception of the intravenous infusion syringe after using.Because the use amount of transfusion needle every day of hospital is huge, according to Grade III Class A hospital's use statistics of transfusion device every year on average, the average transfusion device use amount of a hospital is about 1,000,000 pairs.Therefore, because the intravenous infusion syringe using at present does not all design destroyer, destroy these transfusion needles and need to use artificial and specific purpose tool to its processing of unmaking, time and effort consuming, has also increased the risk of potential pathophoresis.
For make transfusion needle that Naked exposes outside collect and during Destruction in do not injure medical personnel's hands, and venoclysis needle maliciously reused and caused medical cross infection, has manyly just to arise at the historic moment through the transfusion needles of improveing.The transfusion needle of these improvement some with self-locking device, after transfusion, syringe needle can not be reused by locked, some is with self-desttruction equipment, after transfusion, syringe needle is destroyed, but the transfusion needle complex structure of these improvement, operation inconvenience, function singleness, and exposed syringe needle can not be covered up when self-locking or self-destruction.Because the industry is badly in need of a kind of rational in infrastructure, easy to operate venoclysis needle.
Summary of the invention
The technical problem to be solved in the present invention is: provide a kind of rational in infrastructure, easy to operate, self-destruction and can collect the type self-destroyed venoclysis needle of exposed syringe needle after transfusion.
In order to solve the problems of the technologies described above, the present invention by the following technical solutions:
A kind of type self-destroyed venoclysis needle, comprise syringe needle, needle handle, tube for transfusion and self-desttruction equipment, it is characterized in that: described self-desttruction equipment comprises upper cover and base, described tube for transfusion is positioned between upper cover and base, base comprises the body part coordinating with upper cover, the built-up section coordinating with syringe needle, between base body part and built-up section, be connected as a single entity by syringe needle accommodating groove, after infusion-completed, syringe needle return back in syringe needle accommodating groove, base combination part is provided with the through hole that syringe needle passes through, on described, be covered with the tip that can cut off infusion pipeline while pressing down, between upper cover and base, be provided with gear mechanism, the gear of gear mechanism divides two grades, corresponding normal infusion state respectively, cut off infusion pipeline state.
Gear mechanism comprise be arranged on upper cover both sides a pair of barb, be arranged on a pair of elasticity card base of base body part, elasticity card base upwards extends, and stretch into the inner side of a pair of barb, elasticity card base is established two grades, when barb and first grade of elasticity card base fasten, now the tip of upper cover is positioned at the top of tube for transfusion, can not poke tube for transfusion, ensure the unimpeded of infusion pipeline, when upper cover presses down, barb and second gear elasticity card base fasten, and now the tip of upper cover can be poked tube for transfusion, thereby cut-out infusion pipeline, meanwhile barb and second gear card base are mutually locked.
Further, upper cover locates to be provided with the first blend stop above being positioned at syringe needle accommodating groove, base combination part locates to be provided with the second blend stop above being positioned at syringe needle accommodating groove, and the first blend stop and the second blend stop, in the time that syringe needle is collected in accommodating groove, play the effect of syringe needle from deviating from accommodating groove that stop.
Described upper cover and base side are provided with the end face that can prop up needle handle.
Adopt after said structure: after infusion-completed, the syringe needle of transfusion needle can be stowed in syringe needle accommodating groove, when pressing down, upper cover can cut off infusion pipeline, only voucher hand operated can complete self-destruction process, hospital completes the destruction work of transfusion needle without the special staff of outfit, because the syringe needle of transfusion needle is collected in accommodating groove, do not have outside exposedly, do not have the risk of secondary infection disease yet.
