Definitions

  • Syringes require needles to carry out their functions and duties to bring fluids and medications through them to the human body or animal, needle are either free and non-lockable or ordinary or lockable by screwing the plastic side of the funnel such as needle into the duct, which is more attractive for sticks to be locked due to safety and reliability. Because it may be possible in the non-locked syringes when injected or washed out by injection or oily pressure and the severity of the drug and its high viscosity density, so the needle will be removed and caused a lot of problems at the injection time and in some cases like dentistry while the needle is inward and deep inside the gum so if needle gets out of the cylinder, it will become a painful and dangerous course.
  • Needle wringing operation on the outer side of the cylinder duct may not be performed completely by the user and at the time of injection, the injectable person does not understand and during the injection, a portion of the fluid and drug will be removed from the gaps.
  • needle luerlock loses ability to wrap and exhaust and the metal needle remaining and attached to the whole syringe will cause problems with the recycling of polymer materials.
  • the current luerlock mechanism can not be used on syringes that have no nozzle or syringe or needle or syringe placement in the center of the syringe and only syringes with a central syringe can create a luerlock mechanism.
  • the luerlock mechanism is not applicable to glass or metal syringes and this has caused some kind of loss and disability.
  • the invention prevents needle stick as well as the transmission of AIDS, hepatitis and infectious diseases.
  • Stick syringes There is another type of syringe that needle is glued to the syringe and this invention can replace this kind of syringe and any other syringe and also it prevents the use of adhesives and chemicals and their problems and another problem with sticks or luerlock syringes that can not be removed from the syringe after the use of needle or the attachment can be excluded is that after use it can not be removed from the cylinder, which means:
  • a single-use syringe that is not removed or left out can be dangerous and can cause needle stick injections into the hands of a normal user or physician and nurse, or recyclers or scavenger. In addition to causing severe pain, it can wound syringe in the body.
  • needle is moved and locked in a cylinder's outer cavity with a move and click, all syringes can be equipped with this mechanism, even without changing syringe molds and as a consequence of drug leakage or withdrawal, needle is lost when it injected or washed also, the invention of needle stick prevents transmission of infectious diseases such as AIDS and hepatitis and it also helps in the proper recycling of hospital waste.
  • Another goal is to install needle easily on the syringe as well as the possibility of separating them and also the possibility of locking needle and syringe in non-centered syringes which the nozzle or retainer of the needle or proctor is not in the middle but it is at the edge of the syringe head which the luerlock system is not capable of use in such syringes and the guarantor of winning tab in this system can be broken after using the syringe and it plays the role of syringe sealing and it warns the next person that the syringe has already been used to prevent abuse, gathering, washing, packaging and supply in Third World countries or any other area of the world and it does not transmit diseases like AIDS and hepatitis.
  • Plug-and-socket closure system (no need to change the shape of the syringe cylinder):
  • Needle hub changing system needle to change the cylinder and needle structure
  • the changes are small and effective only on the cylinder and in the exterior and in front of the needle hub which the step on the hub or the plastic part of needle is the agent and the point of our goal with the right angle and the tabs at the top of the cylinder can be created on the hub due to the need for one-way pivotal movement and the locking of the hook-like tab or thorn to this step on the hub, this is a hook-shaped piece with a diagonal angle for example 30 or 45 degrees so at the time of inserting and dipping the part of the hub, the headpiece bypassing it and the flexibility that it opens and leaves the way but after crossing a certain point, the tab returns and locks on the stairs and after the deployment and collapse, the full hub with one click catches it and it's not possible to come back and retrieve the needle and keeps needle firmly in place and the problems of leaving needle completely disappear.
  • the invention also embeds along the front and across the tabs of a lockable tab that slip away or are pulled back to the bottom of the finger so this appendage and locking tabs are set aside and needle is released and free and exits.
  • a lockable tab that slip away or are pulled back to the bottom of the finger so this appendage and locking tabs are set aside and needle is released and free and exits.
  • the needle is locked in the syringe cylinder and into various types by engaging the tabs or stairs existing or forming on the parts and components of the syringe to connect the clamping device and to insert the needle and the cylinder and it prevents the components from exiting at the time of injection or washing or other problems and needs.
  • Another type of operation is that we do not have to make and modify the cylinder templates in the form of tabs attached to the new cylinder that are equipped with their own tabs and lock padlock can be installed on syringe cylinder with previous shape and technology so in order to obtain a syringe with a lock system with this captive or circular system, according to the size and mechanism, size and model, and the location of the duct in the syringe and center or other than the center of the duct and other factors, and be designed with other molds and as a new piece, made and manufactured individually, stick on the syringe cylinder and placed in an appropriate place and fitted in any appropriate way.
  • Another aspect of the invention also involves a change in the needle, Hub, and Syringe cylinders with tabs on the needle hub and there are some changes to the cylinder and the hub is locked in the cylinder, which is dealt with in the map area.
  • This invention also reduces the transmission of AIDS and hepatitis and infectious diseases and re-use which is possible by breaking the tabular tab after use, if we do not return the guarantor reactionary and to break the needle in the final step of the tower, we can also use harder material or create slit lines such as breaking onto suitable parts for making a cylinder or lock cap so this could indicate to the next person that the syringe has been used once and the person who has used it has left a sign of this which this would prevent the possibility of washing and packaging and reselling these syringes, because there was a report in a recent report that in third world countries, once used syringes, collected from the hospital and medical centers, they were collected and was
  • FIG. 9 to 12 This image shows a lock hinged cap on a typical syringe with a central nozzle, the types of lock click cap are shown in Figures 9 to 12 which the cap is individually generated and it glued on a normal syringe so there is no need to change syringe molds here and the size of the cap based on the size of the syringe such as the diameter of the cylinder, the nozzle gap or the
