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.

Add-on module (100) for logging the value of an expelled dose from a pen-type drug injector (200), comprising a magnetic sensor system comprising first and second sensor means (745 / 746) as well as a mechanical dose setting and expelling mechanism comprising a magnetic clutch element (240 / 740) which rotates during drug expelling. The system further comprises processor means configured to determine (i) on the basis of measured values from the first sensor means, a rotational position of the clutch element, (ii) on the basis of measured values from the second sensor means, a high-speed condition in which the rotational speed of the clutch element exceeds a given threshold level, and (iii) indicate an error state if the high-speed condition is detected.

A safe medical-drug injector with a collapsable plunger combination thereof is proposed. The injector includes a hub connected with a needle, a hollow barrel, and a collapsable plunger combination including a hollow cannula and a retractable plunger that is telescoped with the hollow cannula. At least a stress adjustable notch is formed at the core of the retractable plunger or in an upper edge of the hollow cannula, and at least one raised portion is formed on an outer lateral side of the retractable plunger near the stress adjustable notch to be correspondingly embedded with at least a depression formed on an inner lateral side of the hollow cannula. The engagement between the raised portion and the depression is released to make the retractable plunger drawn back to the hollow cannula when a following press is applied on the hollow cannula after the safe medical-drug injector completes an injection.

The invention discloses a bladder cancer chemotherapy drug injector, which comprises a urinary catheter; a urinary catheter hole is formed on the outer wall of the urinary catheter near the front end; A support bag is formed on the outer wall between the catheterization hole and the drug delivery hole; a separation ring is formed on the periphery of the support bag; a plurality of injection tubes are formed on the outer wall of the catheter near the rear end; when the support bag and the separation ring are injected with gas, the separation ring is formed. The ring is inflated to abut against the inner wall of the bladder, and the dividing ring divides the bladder into two cavities that are not connected with each other, so that the medication area and the urination area are isolated. The invention can make the urine flowing out of the ureteral orifice to be directly discharged from the body through the catheter, so as to prevent the urine from causing dilution and pollution to the medicine; the medicine can directly reach the inner wall of the bladder, which is beneficial to the absorption of the medicine at the affected part; The urinary catheter is prevented from accidentally slipping out of the body; a separating ring is provided, which can isolate the medicine and the urine, and prevent the medicine from being diluted and polluted by the urine.

The present invention relates to a drug injection cartridge and a drug syringe comprising the same, in which an anti-slip part (100) is formed between a needle part (10) and a cartridge part (20), thereby preventing a rubber film from being expanded by pressure applied to the cartridge part (20), and thus preventing leakage of a drug, thereby improving the accuracy of drug injection.

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.
