Problems solved by technology
In recent years, there have been many patented technologies of self-destructing syringes at home and abroad, but many patented technologies, due to complex structure, high precision, difficult manufacturing, high cost, etc.
It is difficult to lead to mass production. I also applied for a patented technology for a disposable self-destructing syringe on March 23, 2004, and obtained a patent. The patent number is ZL200420007362.5. The top of the seal is broken or broken, causing liquid to flow through the through hole of the seal and self-destructing, but this patented technology has some defects. The injected medicinal liquid will flow out of the push rod from the bottom of the needle tip, and the medicinal liquid cannot be completely injected into the patient’s body, resulting in waste. This patented technology needs further improvement

Embodiment Construction
[0021] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0022] Referring to the accompanying drawings, the present invention comprises a needle point protective cover 1, a needle point 2, a cylinder cover 3, a trocar 4, a seal 5, and a push rod 6, wherein the trocar 4 is perpendicular to the cone at one end thereof. There is a small round hole piercing the two walls of the puncture device 4, a middle hole in the middle of the puncture device communicates with the small round hole 7, a weak zone 8 is provided at the top of the sealing member 5 or the tapered conical hole 9 at the head of the push rod 6, and the push rod Elastic strips 10 and 11 are additionally arranged on the 6. When installing, the sealing member 5 is first installed on the head of the push rod 6, and then they are located inside the cylinder jacket 3 together. During assembly, the rear end of the push rod is The 10 and 11 elastic strips ar...

The present invention relates to a disposable self-destruction syringe with a puncture outfit. It is composed of needle tip protecting sleeve, needle tip, syringe body exterior cover, puncture outfit, sealing component and pushing rod. It is characterized by that in the interior of head portion of said syringe body exterior cover a tightly-matched puncture outfit is mounted, the centre of said puncture outfit has a circular hole, its one end has a pointed cone head, one end of said pointed cone head has a small circular hole perpendicular to the circular hole of said puncture outfit and is communicated with said circular hole positioned in the centre of said puncture outfit, the circular hole and cone head point portion are not communicated. The sealing component is mounted on the pushingrod head portion in the syringe body exterior cover, the top portion of said sealing component has a thin-weak zone, the middle of pushing rod head portion has a tapered conical hole, its rear end isequipped with two elastic strips, under the tapered conical hole an air groove is set, said thin-weak zone also can be designed under the tapered conical hole of pushing rod head portion, its thickness can be controlled at 0.3mm, and the middle of the tightly-matched sealing component is perforated.
Description
technical field [0001] The invention relates to a one-time use self-destruction syringe, more specifically, a syringe which is self-destructed when the injection of liquid medicine is not finished, and can not be used again, which belongs to medical equipment. Background technique [0002] At present, most of the disposable sterile syringes used by medical institutions and individuals at home and abroad do not fully have the characteristics of one-time use in terms of performance due to their structure, and can also be reused. There have been many patented technologies for self-destructing syringes at home and abroad in recent years, but many patented technologies are due to complex structures, high precision, difficult manufacturing, and high costs. It is difficult to lead to mass production. I also applied for a patented technology for a disposable self-destructing syringe on March 23, 2004, and obtained a patent. The patent number is ZL200420007362.5. The top of the seal...
