A drug injector (1) comprising expelling means for expelling a dose of drug from a reservoir, a release member (13) for releasing the drug expelling means, and an actuation member (33) adapted to be moved by a user between an initial, intermediate and actuated position in which the release member is moved to release the drug expelling means. The injector further comprises an electronic capturing system for capturing data representing a dose of drug to be expelled, and a switch (38) for starting initialization of the data capture system, the switch being actuated when the actuation member is positioned in its intermediate position. A spring (34) provides a biasing force against movement of the actuation member between its initial and intermediate position. Thereby the electronic data capturing system is allowed to initialize during the actuation member's movement between the intermediate and the actuated position.

The invention relates to a medicine injector capable of automatically and accurately injecting medicine into a patient's body and a medicine box mounted on the medicine injector to provide the medicine to be injected into the patient. The drug injector may include: a body; a mounting part provided at a lower part of the body and a pinion protruding from the body; a driving part provided inside the body and rotating the pinion protruding from the mounting part; It is provided in the installation part in a manner that can be installed and disassembled, and provides the medicine to be injected into the patient when it is installed. A space for the drug injected by the patient, and a first insertion hole into which the pinion is inserted is formed on the bottom surface, and a discharge port from which the drug stored in the space is discharged is formed on the other side; and a piston member that discharges the stored drug to the discharge port For medicine in space, the piston part includes a piston rod and a piston.

The invention provides a multi-chamber dosage-free airtight sterile medicine injector and belongs to the field of medical apparatuses and instruments. The multi-chamber dosage-free airtight sterile medicine injector is in a shape of a flying saucer and is divided into four to eight same-sized sector spaces, each space is divided into two chambers, a round shared space is located at the position of the circle center, the center of the medicine injector is connected with a thin silicone tube, and the far end of the silicone tube is connected with a drainage tube at an operative site. Weak easily-opened areas are arranged among the medicine storage chambers and between the medicine storage chambers and the round shared space. A C-shaped magnet matched with the round shared space in size is arranged on the outer side of the two-layer bag wall of the round shared space and is attracted with a round irony plate to seal the two-layer bag wall, and a gap of the C-shaped magnet is aligned to the weak easily-opened areas between the sector spaces prepared for medicine injection and the round shared space and accordingly serves as a unique channel of the center thin silicone tube for the sector spaces prepared for medicine injection and the round shared space. The multi-chamber dosage-free airtight sterile medicine injector can achieve multi-time dosage-free medicine injection under the airtight sterile condition, avoids the possibility that the medicine in the dosage process is polluted by microorganisms and obviously reduces occurrence rate of lethal intracranial infection.

The present invention relates to a portable automatic drug injector having convenient portability and handling and enabling an accurate amount of a drug to be safely injected. The present invention provides a portable automatic drug injector capable of: easily performing an injection treatment so as to inject a drug without a separate switch operation, by implementing a novel automatic drug injection method enabling the drug to be automatically injected into the skin by using a guide acting as a switch touching and pushing the skin when the drug is injected, particularly, ensuring the accuracy and safety of a treatment by accurately adjusting an injection amount of the drug; providing a customized treatment according to the conditions of various patients, convenient portability, easy handling and easy and accurate treatment regardless of a user's proficiency by having various types of manipulation means, which enable an injection amount of the drug and an injection depth to be adjusted, and a rechargeable battery embedded therein.
