Abstract
The utility model discloses a self-destruction type disposable syringe which comprises a syringe body, a piston, a push rod, a push handle and a syringe needle. The syringe needle is connected with the syringe body through a pintle and a needle file, and a needle file hole communicated with the syringe body and the syringe needle is formed in the needle file. The self-destruction type disposable syringe is characterized in that a needle file rod is arranged on the front end face, corresponding to the needle file hole, of the piston, a breaking groove is formed in the needle file seat, when the self-destruction type disposable syringe is used, liquid medicine in the syringe body is injected into a human body through pushing of the piston by the needle handle and the push rod, when the piston reaches the front end of the syringe body, the liquid medicine in the syringe body is pushed into the human body completely, and meanwhile, the needle file rod on the front end face of the piston is pushed into the needle file hole so that the needle file hole is blocked. Due to the fact that the breaking groove is formed in the needle file rod, when the needle file rod enters into the needle file hole, the needle file rod can be broken through pushing or drawing of the needle handle so that the syringe is self destructed, and therefore cross infection caused by repeated usage is avoided. The self-destruction type disposable syringe has the advantages of being simple in structure, low in manufacturing cost, safe in usage, simple in operation, free from repeated usage, capable of avoiding the cross infection effectively and the like.
Description
Technical field
This utility model relates to technical field of medical instruments, the re-use preventing once-used syringe that specifically a kind of safety is good, prevent cross infection.
Background technology
cross infection occurs when giving the injection of patient or animal, the necessary disposable use of hypodermic syringe, after use namely as garbage disposal, at present, using maximum disposable syringes is to comprise syringe, piston, push rod, push away handle and syringe needle, the syringe needle rear end is provided with pintle, the syringe front end is provided with needle stand, syringe needle is connected with needle stand through pintle with syringe, needle stand is provided with the needle stand hole that is communicated with syringe and syringe needle, piston is located in syringe, push rod inserts the syringe front end and is fixedly connected with piston, the rear end with push away handle and be fixedly connected with, the push rod circumferential array has at least 3 guide plates, in case the axial dipole field phenomenon occurs in throw-out lever when pushing piston is axially advanced along syringe, reaching injection acts on smoothly, its deficiency is: because individual physician quality is relatively poor, can not prevent from reusing, frequent pin Reusability repeatedly, do not guarantee the harm that the patient is not infected by antibacterial, and, also cause some illegal retailers that used syringe is banished market again, cause the malpractice that should not occur to occur.
Summary of the invention
The purpose of this utility model is to solve above-mentioned the deficiencies in the prior art, provide a kind of simple in structure, production cost is low, effectively inoculate the re-use preventing once-used syringe that device causes cross infection.
The technical scheme that its technical problem that solves this utility model adopts is.
A kind of re-use preventing once-used syringe, comprise syringe, piston, push rod, push away handle and syringe needle, the syringe needle rear end is provided with pintle, the syringe front end is provided with needle stand, and syringe needle is connected with needle stand through pintle with syringe, and needle stand is provided with the needle stand hole that is communicated with syringe and syringe needle, piston is located in syringe, push rod inserts the syringe front end and is fixedly connected with piston rear end, and putting back-end is fixedly connected with pushing away handle, it is characterized in that place, the corresponding needle stand of piston nose face hole is provided with the needle stand bar.The needle stand bar is provided with snap slot.
when this utility model uses, pass through needle handle, when the push rod pushing piston advances in syringe, the medicinal liquid in syringe is injected in human body, when piston arrives syringe front end, medicinal liquid in syringe all pushes in human body, this moment, the needle stand bar of piston nose face also was pushed in the needle stand hole and with the needle stand hole plug, because the needle stand bar is provided with snap slot, after the needle stand bar enters the needle stand hole, push away or pull needle handle all can cause fractureing of needle stand bar, make the syringe self-destruction, the cross infection of having stopped to reuse and having brought, have simple in structure, production cost is low, use safety, simple to operate, avoid reusing, effectively the protective inoculation device causes the advantages such as cross infection.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment:
The utility model is described in further detail below in conjunction with Fig. 1:
as shown in the figure, a kind of re-use preventing once-used syringe, comprise syringe 1, piston 2, push rod 3, push away handle 4 and syringe needle 5, syringe needle 5 rear ends are provided with pintle, syringe 1 front end is provided with needle stand, syringe needle 5 is connected with needle stand through pintle with syringe 1, needle stand is provided with the needle stand hole that is communicated with syringe 1 and syringe needle 5, piston 2 is located in syringe 1, push rod 2 inserts syringes 1 and is fixedly connected with piston 2 rear ends, push rod 3 rear ends with push away handle 4 and be fixedly connected with, the structure of above-mentioned each ingredient and the interconnected relationship between them are same as the prior art, this does not give unnecessary details, of the present utility modelly be characterised in that piston 2 places, the corresponding needle stand of front end faces hole are provided with needle stand bar 6, needle stand bar 6 is provided with snap slot, needle stand bar 6 is just in time facing to the needle stand hole, the diameter of needle stand bar 6 is slightly less than the needle stand bore dia, the snap slot operated by rotary motion is at needle stand bar 6 lower end parts, during use, pass through needle handle, when the push rod pushing piston advances in syringe, the medicinal liquid in syringe is injected in human body, when piston arrives syringe front end, medicinal liquid in syringe all pushes in human body, this moment, the needle stand bar of piston nose face also was pushed in the needle stand hole and with the needle stand hole plug, because the needle stand bar is provided with snap slot, after the needle stand bar enters the needle stand hole, push away or pull needle handle all can cause fractureing of needle stand bar, make the syringe self-destruction, the cross infection of having stopped to reuse and having brought, have simple in structure, production cost is low, use safety, simple to operate, avoid reusing, effectively the protective inoculation device causes the advantages such as cross infection.
