Abstract
A disposable safety self-destruction syringe comprises a needle cylinder component and a needle rod component. A clamping claw (5) is arranged inside a cone head hole of a cone body needle holder (3) of the needle cylinder component, conical clamping teeth (4) are arranged at the top end of a plastic core rod (8) of the needle rod component, and axially symmetric stripping points (7) are arranged at two positions of the middle of the plastic core rod (8). The disposable safety self-destruction syringe has the advantages that a self-destruction characteristic of the syringe is automatically effective after fixed dosage is injected by the aid of the disposable safety self-destruction syringe, once the self-destruction characteristic is effective, the syringe cannot be reused, a self-destruction function of the syringe is truly realized, reuse of the disposable safety self-destruction syringe is effectively prevented, and the disposable safety self-destruction syringe is safe and reliable and is easy to be produced, convenient in assembly and low in production cost.
Description
Technical field
This utility model relates to the medical apparatus technical field, a kind of specifically disposable safety self-ruined syringe.
Background technology
Estimate that according to World Health Organization (WHO) injection is as treatment means common in the medical procedure, every year is implemented 12,000,000,000 person-times in the whole world approximately, and wherein about 50% is unsafe.The factor that causes dangerous injection is a lot, and wherein the problem that should pay close attention to especially is the utilization again of injection device non-sterile and syringe.The whole world infects hepatitis C virus 2,300,000 to 4,700,000 people, patients infected hiv 8 to 160,000 people because of about 800 to 1,600 ten thousand people of hepatitis B on the dangerous infectable infection every year.Interrelated data shows have 63% to be that IDU infects in China's patients infected hiv.On 63.5 ten thousand the prophylactic immunization points in the whole nation, what can accomplish that a people one pin one is managed or disposable injection is comparatively safe is 30.5% only, is 51.6% unexpectedly and adopt the dangerous injection of a people one pin (not changing needle tubing).The hepatitis B that dangerous injection causes, hepatitis C and aids transmission have become serious public health problem.
In order really to reach disposable purpose, the someone has attempted multiple self-destruction scheme.For example, water-swellable, a dress watt reed are ruined type, elastic component and are ruined to contract in type, the syringe needle and ruin that type, needle-penetration are ruined type, type, the telescopic type etc. of ruining of retaining are ruined in the element fracture.But in the production and clinic trial of reality, or meet the deliquescence body easily and be difficult for long-term storage because of expanding material exists, or problem because of adopting hardware to get rusty easily, or because of the complicated difficult shortcomings such as inconvenience, production cost height of producing, assemble of design technology, its research and production work have run into certain resistance.But in order thoroughly to stop the repeated use of disposable syringe, fundamentally protect people's life and health, must design the disposable syringe that a kind of safety well can self-destruction.
The utility model content
The purpose of this utility model is that design is a kind ofly avoided reusing, safe and reliable disposable self-destruction syringe.
This utility model disposable self-destruction syringe, comprise: syringe assembly and shank assembly, be provided with claw 5 in the cone head hole of the cone needle stand 3 of described syringe assembly, the top of the plastics core bar 8 of described shank assembly is provided with taper latch 4, and is provided with at plastics core bar 8 middle parts that two places are axisymmetric to break a little 7.
Described syringe assembly comprises: plastic wrapper 9, entry needle 2 are sleeved on the cone needle stand 3 hermetically, the entry needle 2 outer pin medicated caps 1 that are set with.
Described shank assembly comprises: plastics core bar 8, and plastics core bar 8 lower ends are provided with promotion dish 11, banking stop 10, and plastics core bar 8 front ends also are provided with piston 6.
Under the material situation of equality strength, the total sectional area of 7 connecting places is a little broken less than the minimum sectional area that is stuck in cone needle stand 3 inner conical latches 4 in described plastics core bar 8 middle parts, and the minimum sectional area of the total sectional area of 7 connecting places a little less than claw 5 broken at plastics core bar 8 middle parts.
This utility model disposable safety self-ruined syringe is achieved in that at first opens banking stop 10, extracts required liquid medicine injection, can inject; When injection was finished, plastics core bar 8 was pushed to the top, and conehead latch 4 passes cone head hole, was established claw 5 in the cone head hole and blocked, and piston 6 can not be return.This moment, if breaking a little on the plastics core bar 87 will be broken post-tensioning by force, thereby plastics core bar 8 is separated into two sections, can't continue use, reaches self-destruction.
The advantage of this utility model disposable safety self-ruined syringe is: this syringe self-destruction characteristic after having injected fixed dosage comes into force automatically, and in a single day the self-destruction characteristic comes into force, and syringe just can not be repeated to use; The real self-destroying function of realizing effectively prevents to reuse, and is safe and reliable, is easy to produce, easy to assembly, low production cost.
Description of drawings
Fig. 1 is the structural representation of disposable self-destruction syringe.
Fig. 2 is the self-destruction view of disposable self-destruction syringe.
The specific embodiment
According to Fig. 1, shown in Figure 2, a kind of disposable safety self-ruined syringe, comprise: syringe assembly and shank assembly, be provided with claw 5 in the cone head hole of the cone needle stand 3 of described syringe assembly, the top of the plastics core bar 8 of described shank assembly is provided with taper latch 4, and is provided with at plastics core bar 8 middle parts that two places are axisymmetric to break a little 7.
Described syringe assembly comprises: plastic wrapper 9, entry needle 2 are sleeved on the cone needle stand 3 hermetically, the entry needle 2 outer pin medicated caps 1 that are set with.
Described shank assembly comprises: plastics core bar 8, and plastics core bar 8 lower ends are provided with promotion dish 11, banking stop 10, and plastics core bar 8 front ends also are provided with piston 6.
Under the material situation of equality strength, the total sectional area of 7 connecting places is a little broken less than the minimum sectional area that is stuck in cone needle stand 3 inner conical latches 4 in described plastics core bar 8 middle parts, and the minimum sectional area of the total sectional area of 7 connecting places a little less than claw 5 broken at plastics core bar 8 middle parts.
