Abstract
Avoid reusable syringe, belong to technical field of medical instruments.Including syringe, shank, the syringe needle mounting seat of plunger and syringe front end, the center of syringe needle mounting seat is through liquid-through hole, plunger is connected to the front end of shank and is placed in syringe, it is characterized in that, the front end liquid-through hole mouth of described syringe is provided with boss, the front end of plunger is provided with mushroom head, mushroom head is connected to plunger front end by connecting rod, the rectangular triangle of described boss, boss is inclined-plane or cambered surface towards the face of syringe, boss towards liquid-through hole for plane, liquid-through hole is close to the mushroom head containing cavity being provided with blocking liquid-through hole at boss, the diameter of described mushroom head is slightly larger than the distance between two opposite face boss.Present configuration is rationally simple, manufactures easily, low cost.After this syringe accomplishes single use, it is impossible to second time uses again, it is ensured that use safety, it is to avoid syringe is because repeating to cause virus cross infection.
Description
Technical field
The present invention relates to the structure of a kind of syringe, a kind of syringe having automatic blocking and damaging structure, to guarantee the disposable syringe guaranteeing safe and sanitary that cannot be used by secondary, belong to technical field of medical instruments.
Background technology
Syringe is to enter in patient body by drug injection, to reach a kind of medical apparatus and instruments for the treatment of effect.Before healthcare givers is to patient injection, first medicine is introduced in syringe, the most again by the syringe needle on syringe, this drug injection is entered in patient body.Traditional syringe there are much potential danger, by improper use when, the health of people can cause the most serious injury and bad impact.Traditional syringe structurally cannot be avoided reusing, and when in syringe injection medicine a to patient body, the blood of this patient, remaining medicine, antibacterial, virus or other morbid substance are likely to remain on syringe or its syringe needle.When again giving second patient injection with same syringe, it is possible to by the germina infection of a upper patient to second patient, and infect to identical pathogenic bacteria.At present, have been devised by many disposable syringes, be widely used in medical field, but.The solution of these prior arts is the most highly satisfactory, or adds cost because of the most complicated, or in default of reliability, or due to other defect.Due to ordering about of economic interests, there is people that disposable ordinary syringe secondary is used, be even used for multiple times.Contaminated syringe also constitutes the most serious threat to the health of operator, needs to avoid being injured by contaminated syringe.Therefore, the disposable syringe that a kind of impossible secondary uses is designed, it is ensured that use safety, be the urgent needs in market.
Summary of the invention
The purpose of the present invention is exactly the demand for meeting market, and design one avoids reusable syringe.After this syringe can accomplish first use, it is impossible to reuse, and product structure is simple, manufactures easily, safe and convenient to use.
The object of the present invention is achieved like this, avoid reusable syringe, including syringe, shank, the syringe needle mounting seat of plunger and syringe front end, the center of syringe needle mounting seat is through liquid-through hole, plunger is connected to the front end of shank and is placed in syringe, it is characterized in that, the front end liquid-through hole mouth of described syringe is provided with boss, the front end of plunger is provided with mushroom head, mushroom head is connected to plunger front end by connecting rod, the rectangular triangle of described boss, boss is inclined-plane or cambered surface towards the face of syringe, boss towards liquid-through hole for plane, liquid-through hole is close to the mushroom head containing cavity being provided with blocking liquid-through hole at boss, the diameter of described mushroom head is slightly larger than the distance between two opposite face boss, the part that shank end is connected with shank torr is the taper being drawn out easily.
Described mushroom head passes through connecting rod socket connection in plunger front end.
Described plunger is rubber stopper, is provided with sealing ring between plunger and syringe, and sealing ring is inlaid on plunger outer wall in the seal groove arranged.
Described socket connection is connecting rod and mushroom head socket connection or connecting rod and plunger socket connection.
Avoid reusable syringe, medicinal liquid is first drawn before using, during use, plunger is advanced into the front portion of syringe, mushroom head enters liquid-through hole close in the mushroom head containing cavity at boss, plunger can not fall back, if somewhat pulling at shank, due to connecting rod and mushroom head socket connection, mushroom head the most individually comes off at containing cavity and blocks liquid-through hole, syringe can no longer be used, the part that shank end is connected with shank torr simultaneously uses the pyramidal structure being drawn out easily, when firmly plunger outward being drawn, shank torr separates with shank, reach disposable purpose, effectively prevent syringe from being used by secondary.
Present configuration is rationally simple, manufactures easily, low cost.After this syringe accomplishes single use, it is impossible to second time uses again, it is ensured that use safety, it is to avoid syringe is because repeating to cause virus cross infection.

Detailed description of the invention
Such as Fig. 1, Fig. 2, Fig. 3, Fig. 4, shown in Fig. 5, avoid reusable syringe, including syringe 1, shank 2, the syringe needle mounting seat 4 of plunger 3 and syringe front end, the center of syringe needle mounting seat is through liquid-through hole, plunger is connected to the front end of shank and is placed in syringe, the front end liquid-through hole mouth of described syringe is provided with boss 6, the front end of plunger is provided with mushroom head 5, mushroom head is connected to plunger front end by connecting rod 8, the rectangular triangle of described boss, boss is inclined-plane or cambered surface towards the face of syringe, boss towards liquid-through hole for plane, liquid-through hole is close to the mushroom head containing cavity being provided with blocking liquid-through hole at boss, the diameter of described mushroom head is slightly larger than the distance between two opposite face boss, the part that shank end is connected with shank torr is the taper being drawn out easily.Mushroom head passes through connecting rod socket connection in plunger front end.Plunger is rubber stopper, is provided with sealing ring 7 between plunger and syringe, and sealing ring is inlaid on plunger outer wall in the seal groove arranged.Socket connection is connecting rod and mushroom head socket connection or connecting rod and plunger socket connection.Medicinal liquid is first drawn before using, during use, plunger is advanced into the front portion of syringe, plunger arrives syringe front end, mushroom head enters liquid-through hole close in the mushroom head containing cavity at boss, plunger can not fall back, if somewhat pulling at shank, due to connecting rod and mushroom head socket connection, mushroom head the most individually comes off at containing cavity and blocks liquid-through hole, simultaneously, the part that shank end is connected with shank torr uses the pyramidal structure being drawn out easily, when firmly plunger outward being drawn, shank torr separates with shank, syringe can no longer be used, reach disposable purpose, effectively prevent syringe from being used by secondary.Present configuration is rationally simple, manufactures easily, low cost.After this syringe accomplishes single use, it is impossible to second time uses again, it is ensured that use safety, it is to avoid syringe is because repeating to cause virus cross infection.
