  • Publication number: 20240325644
    Abstract: A conversion mechanism includes a driving piston set and a conversion connecting base. A piston cylinder of the driving piston set is connected to a medicament container containing medicament and a needle output mechanism having needle set through an input one-way valve and an output one-way valve of a valve. A piston rod mounted in the piston cylinder is detachably connected to and driven by a driving mechanism, such that the conversion mechanism in combination with the needle output mechanism forms an injection module. The medicament container and the injection module relating to safety and hygiene in the injector can be used once and be disassembled and discarded after user. With the driving mechanism externally connected to the conversion mechanism, the driving mechanism does not come into contact with the medicament during injection.

  • Patent number: 11839748
    Abstract: A plunging apparatus for a syringe is applied to connect with a driving assembly of an injection device and a medicine vial. The plunging apparatus has a pushing element connected with a connection element by a unidirectional check element. The rear end of the connection element is connected with a pushing rod. The front end of the pushing rod has an ejection element and a spring. A threaded collar is mounted around the pushing rod, and an injection rod is mounted in the pushing rod. The connection element is inserted into a rear opening of the medicine vial. Engagement hooks on the ejection element can be pressed by medicine vial. The spring forces the ejection element to move forward to push the pushing element to abut the piston. Accordingly, the medicine vial can be used immediately after being combined with the injection device without discharging air manually.

  • Publication number: 20230355891
    Abstract: A needle output mechanism which can be connected to a pharmaceutical agent container and a drive module. The base of the needle output mechanism is equipped with a movable connecting member, a needle set, a needle output operation assembly, and a needle retraction operation member. The connecting member is connected to an adapter mechanism. During injection, the needle set in the connecting member can be driven by the needle output operation assembly, and using a hard needle disposed passing through a soft needle and out from the base, outputs a needle which can directly puncture the human body, successively driving the hard needle (133) to disengage from the soft needle and inject the pharmaceutical agent solution by way of the drive module. After injection, the needle retraction operation member can retract the connecting member and the soft needle thereby facilitating operation.

  • Publication number: 20230330342
    Abstract: An injector comprises a medicament container, an injection module and a driving mechanism. The injection module comprises a conversion mechanism and a needle output mechanism connected to each other. The conversion mechanism is assembled and connected to the medicament container. A driving piston set in the conversion mechanism is assembled and connected to the driving mechanism. A needle set in the needle output mechanism is used for piercing a human body. The driving mechanism drives the driving piston set to convey a medicament liquid in the medicament container to the needle set for injection, such that the medicament container and the injection module, which are related to safety and hygiene, are of single use and are disassembled and discarded after being used. The conversion mechanism is externally connected to the driving mechanism, so that the driving mechanism does not contact the injection medicament liquid during injection and can be reused, thereby reducing material waste.
