Problems solved by technology

[0002] Insulin syringes are small-dose syringes specially used for injecting insulin. Like large-dose syringes, in order to avoid cross-infection of blood, insulin syringes now use disposable products, but this kind of disposable syringes, if not destroyed artificially, are Reusable, in order to prevent the existing disposable insulin syringes from being reused to cause cross-infection and spread diseases, it is an inevitable choice in the industry to design self-destructing disposable insulin syringes
Most of the self-destruct mechanisms of existing insulin syringes are set at the front end of the syringe, but for insulin syringes with small inner diameters, the reasonable setting of the self-destruct mechanism is limited. The syringe with the destruction mechanism set at the front end is not suitable for injecting insulin

Embodiment Construction

[0024] Referring to Figure 1, Figure 2, Figure 10 , the present invention comprises a hollow syringe 1, a push rod 2 sliding in the syringe 1 and a rubber plug 3 installed on the front end of the push rod 2, the front end of the syringe 1 is formed with a needle seat 4, and the front end of the syringe 1 The rear end is provided with a diameter-increased part, and a self-destruct mechanism is arranged in the enlarged part. The self-destruct mechanism is composed of a backstop ring 5 and a support ring 6. The backstop ring 5 is supported and fixed by the support ring 6. The upper end of the anti-retraction ring 5 is provided with an elastic pawl 7 gathered toward the center, and the lower end is provided with an elastic pawl 8. The number of the elastic pawl 7 and the elastic pawl 8 is at least two, and the inner wall of the syringe 1 is provided with an elastic pawl accordingly. The claw 8 is embedded in the groove 9, and the push rod 2 is provided with a frustum 10 engaged w...

Abstract

The self-destroying insulin injector includes one tube, one push rod, one rubber stopper and one self-destroying mechanism set inside the back end of the tube in great diameter. It features the self-destroying mechanism comprising one no-back ring with elastic ratchet in the upper end and elastic opening jaw in the lower end, and one support ring to support the no-back ring. The self-destroying mechanism is safe and reliable, and has reasonable structure, convenient assembling and capacity to ensure low medicine liquid residue.

Description

technical field [0001] The invention belongs to a medical appliance, in particular to a disposable self-destruct insulin syringe. Background technique [0002] Insulin syringes are small-dose syringes specially used for injecting insulin. Like large-dose syringes, in order to avoid cross-infection of blood, insulin syringes now use disposable products, but this kind of disposable syringes, if not destroyed artificially, are Can be reused, in order to prevent the existing disposable insulin syringes from being reused to cause cross-infection and spread diseases, it is an inevitable choice in the industry to design self-destructing disposable insulin syringes. Most of the self-destruct mechanisms of existing insulin syringes are set at the front end of the syringe, but for insulin syringes with small inner diameters, the reasonable setting of the self-destruct mechanism is limited. The syringe whose destruction mechanism is arranged at the front end is not suitable for inject...
