Definitions

  • the utility model relates to a medical instrument accessory, in particular to a disposable safety syringe (0K) needle.
  • syringe needles are a common accessory for medical devices. It consists of a needle tube and a needle tube base. To prevent cross-infection, single-use use is gaining more and more attention.
  • the widely used disposable syringe needles are a management concept, and the performance is not "disposable". They can be used repeatedly, leaving hidden dangers to cross-infection and easily causing disease transmission.
  • the needles are mostly exposed, it is easy to puncture and scratch the doctors and patients, causing new cross-infection. Because the national standard needle has a single structure, its use is limited. Disclosure of invention
  • the technical problem to be solved by the utility model is to overcome the above-mentioned shortcomings of the prior art, and provide a disposable single-use safety syringe (0K) needle with simple structure, convenient use, stability, and good safety performance.
  • a disposable safety syringe ( ⁇ ) needle which comprises a needle tube, a needle tube sleeve, a needle tube seat, a seal ring, and a spring, and is characterized in that: the end portion is provided with a ring shape
  • a needle tube sleeve with a through-hole in the center of the step is installed with a ring-shaped step sleeve sealing ring at the rear end of the needle tube in the front through-hole, and an internal cavity is provided in the central through-hole of the needle tube holder.
  • the sealing ring ensures the sealing and pushing function of the needle tube and the needle tube seat.
