Disposable double auto-disable syringe

Abstract

The invention discloses a double auto-disable syringe. The double auto-disable syringe comprises a biconical connector, a cylinder, a core pin, a rubber plug and an injection needle, wherein an auto-disable device comprises the biconical connector, the cylinder and the core pin; the biconical connector is arranged in the rubber plug, and a round hole is formed in the right center of the top of therubber plug. When a medicinal solution is completely injected, the biconical connector is inserted into the conehead of the cylinder and is integrated into a whole with a cylinder left-hand device, so that the biconical connector and the cylinder can be connected into a whole; when the core pin is pulled back, the conehead of the biconical connector is separated from the core pin and the rubber plug, so that the round hole in the top of the rubber plug is communicated with the opening of the core pin, the rubber plug loses the sealing function, and the medicinal solution cannot be sucked; andthe conehead of the biconical connector is separated from the core pin, so that the area of the core pin in left-hand threading with the rubber plug is reduced, the rubber plug is separated from thecore pin, the syringe is scraped and cannot be reused, and a double auto-disable function is achieved.

Description

Technical field: [0001] The invention relates to a disposable medical appliance, in particular to a disposable double self-destruct syringe Background technique: [0002] Among the blood-borne diseases in the world, AIDS is the scariest one. According to the survey and statistics of WHO (World Health Organization), there are more than 36 million AIDS patients in the world, which has seriously threatened the health of human beings around the world. [0003] There are five main routes of transmission of HIV: ① Sexual transmission, the primary transmission route of the global AIDS epidemic, including genital, anal and oral sexual contact, the incidence rate is 70-80%; ② Transmission among intravenous drug users, Sharing drug injection equipment is a stable and continuously increasing risk factor, with an incidence rate of 3-10%; ③Transmission through blood products, using whole blood, red blood cells, fresh frozen plasma and platelets provided by a single blood donor, or using...

Problems solved by technology

[0006] 1. The medicine injected in the hospital is generally quantitative. When the self-destructing syringe similar to the above is used, when the cartridge is in contact with the elastic snap ring, there is still a gap between the rubber plug and the bottom of the syringe barrel, that is, the medicine in the syringe is not It is completely finished, and to be completely finished, it is necessary to push the core rod hard, so that the cartridge overcomes the resistance with the elastic snap ring. When the medicine is finished, the cartridge and the elastic snap ring are stuck and self-destructed, and the core rod is pushed hard When it is used, it is easy to cause vibration, causing the injection needle to vibrate in the patient's body, causing pain to the patient, and may cause greater damage. However, if the resistance formed when the card holder and the elastic snap ring are stuck, it will inevitably cause the card holder and the elastic clip to be locked. The resistance after the ring is stuck is greatly reduced, and it will be difficult to play the anti-reuse function

[0007] 2. For some self-destructing syringes, although the design has made the card seat and the elastic snap ring get stuck, there is a greater locking force, but if the core rod is pulled out with force, the core rod can often be pulled out, causing it to be damaged. Rinse and use or be used as a toy by children, causing infection risk

[0008] 3. In the existing self-destructing syringes, if the core rod is pulled out with force, the core rod can often be pulled out, causing various parts to be easily recycled by unscrupulous traders, which may cause the risk of infection

[0009] 4. The barrel of the existing disposable syringes remains intact. In reality, some children pick them up to make water-shooting toys, and some unscrupulous vendors recycle and reuse them privately.
