Problems solved by technology

But this patent also has some deficiencies, as the self-destructing syringe can also be disassembled and reinstalled in a certain way, although it will cause water leakage during use, it feels like it can be used again, and it cannot be said that it has really achieved completeness. Disposable use, its structure needs to be further improved

Embodiment Construction

[0023] The present invention will be further described below in conjunction with accompanying drawing and embodiment:

[0024] With reference to the accompanying drawings, the disposable self-destructing syringe of the present invention includes a needle point 1, a cylinder body 2, a core rod 3, a non-return member 7, a sealing plug 10 and a needle cover 14, and it is provided with a spine on the core rod 3. Alveolar 4, back-limiting step 5, installation hole 6, first repeated movement part 11, second repeated movement part 12 and broken part 13 (see figure 1 ), the non-return part 7 is provided with non-return stabs 8 and ratchets 9, when assembled, the non-return part 7 enters the return-limiting step 5 through the installation hole 6, and the ratchet 9 withstands the return-limiting step 5, and then puts on the sealing plug 10 Push into the bottom of cylinder 2 (see figure 1 , figure 2 ).

[0025] When in use, pull back the core rod 3 to extract a small amount of liqu...

Abstract

The invention relates to a disposable self-destruction syringe which can only fill up the liquid medicine at one time. More specifically, the self-destructing part has started to work during the injection process after the medicinal liquid is full. It can only be pushed forward and can no longer be withdrawn. It is a one-time use self-destructing type that cannot be used again in any way. A syringe, which includes a needle point (1), a cylinder body (2), a core rod (3), a non-return member (7), a sealing plug (10) and a needle sleeve (14). It is characterized in that: the core rod (3) is provided with a ratchet groove (4), a return limiting step (5), a mounting hole (6), a first repetitive motion part (11), a second repetitive motion part (12) and At the broken part (13), the non-return member (7) is provided with non-return stabs (8) and ratchets (9). The invention is more suitable for micro-injection, immunization injection and insulin injection with less residual amount, is convenient and simple to use, and self-destructs after one-time injection.

Description

technical field [0001] The invention relates to a medical syringe, more specifically to a disposable self-destructing syringe. Background technique [0002] At present, in order to prevent the cross-infection of iatrogenic diseases at home and abroad, the use of disposable self-destructing syringes has been required to achieve self-destructing effect structurally. For example, some self-destructing syringes known at home and abroad are mostly in the form of destroying the piston and core rod when the syringe is finished injecting the liquid medicine (that is, as long as there is a little liquid medicine), the piston cannot be destroyed and can be repeated. use. In June 2003, in order to improve the deficiencies of the above technologies, the company designed a disposable self-destructing syringe that self-destructs and takes effect from the beginning of injecting the medicinal solution, that is (a disposable self-destructing syringe that can only extract the medicinal solut...
