[Problem] The purpose of the present invention is to provide a portable anticancer agent container for preventing exposure and infection to the human body caused by chemical solution leakage that arises during a removal operation of a coupling connector at the time of system cleaning using a cleaning solution. [Solution] Provided is a pressurization-type drug injector having a drug exposure preventive function and having a system cleaning function, the pressurization-type drug injector comprising: a reservoir that has a chemical solution filling opening and a chemical solution discharging opening; a pressurization deformation means that undergoes pressurization and deformation by the injection of a chemical solution and that pushes out the chemical solution by a force caused by restoration of the pressurization and deformation; a flow rate control means that adjusts the flow rate of the chemical solution by resistance; a system cleaning port that includes a cleaning solution injection opening, a chemical solution filling opening, and a liquid discharging opening; and a case that contains therein said reservoir, said pressurization deformation means, and said system cleaning port. The case has openings respectively in the vicinity of the chemical solution filling opening, the system cleaning injection opening, and the chemical solution discharging opening. The chemical solution being filled is filled into the pressurization deformation means from the chemical solution filling opening of the reservoir, and moves from the chemical solution discharging opening of the reservoir to the exterior of the container via the flow rate control means. A cleaning solution is injected from the injection opening of the cleaning port arranged downstream from the flow rate control means, and moves to the exterior of the container. The pressurization-type drug injector having a drug exposure preventive function is characterized in that the periphery of the cleaning port is completely covered by a sterile seal, and thus, the cleaning port injection opening is kept clean until use.

The application discloses a double-cheek local medicine injector and an injection method thereof, and relates to the technical field of medical treatment.The injector comprises an injection barrel, a liquid outlet barrel connected to the front end of the injection barrel, a connecting barrel sleeved on the periphery of the liquid outlet barrel, an opening of the connecting barrel being attached to one side of the injection barrel, a needle connected to one end of the connecting barrel of the injection barrel, a push rod slidingly fitted in the hollow part of the injection barrel, a piston head attached to the inside of the injection barrel being connected to the side of the push rod facing the liquid outlet barrel, and a clamping mechanism arranged on the periphery of the injection barrel for clamping the connecting barrel.The clamping mechanism can be used to quickly disassemble the needle, and the medical staff does not need to laboriously pull out the needle, and the medical staff does not need to put the hand into the oral cavity of the patient during the process of pulling out the needle, the connecting barrel can be detached by directly rotating the clamping mechanism at the edge of the needle, and the medical staff is facilitated to replace the injection barrel.

The invention relates to a reusable automatic injector, and belongs to the technical field of medicine injectors. The invention provides a reusable automatic injector. The reusable automatic injector comprises a pen body, a refill frame, a clutch rod, an injection button, a small push rod and a torsional spring, the injection structure comprises injection teeth and clutch teeth, when the refill frame is connected to the pen body, the injection teeth and the clutch teeth are combined, the injection button is pressed down to enable the clutch rod to move downwards, the lower section of the clutch rod is connected with the injection teeth, and the clutch rod rotates under the torsion effect of the torsion spring and drives the injection teeth and the clutch teeth to rotate synchronously. When the pen core frame is separated from the pen body, the clutch teeth move downwards and are separated from the injection teeth, and the small push rod is driven by the clutch teeth to rotate downwards so as to push the rubber plug to achieve the injection purpose. The torsion spring driven injection and reliable reuse of the automatic injector are realized, and the clutch rod and the injection teeth are combined by pressing the button, so that the torsion spring driven injection is realized.

A drug infusion device according to the present invention includes a drug injector that electrochemically drives an electroosmotic pump to inhale a drug from a drug reservoir and discharge the inhaled drug into an infusion target, and a controller that outputs a control signal to the drug injector corresponding to a volume-based infusion sequence that drives the electroosmotic pump in an immediate infusion mode, the volume-based infusion sequence including at least one pulse block that defines voltage pulses or current pulses to be applied to the electroosmotic pump, each pulse block defining a pair of pulse signals that include a forward pulse and a reverse pulse that are applied to the electroosmotic pump and generate alternating negative and positive pressures, and the electroosmotic pump generates alternating negative and positive pressures for each pulse block to inhale and discharge the drug.

The present invention provides a drug injector that allows for easy attachment and detachment of the nozzle to the barrel, and that enables the nozzle's position relative to the barrel flange to remain constant at all times. [Solution] The drug injector 1 comprises a barrel 10 into which the drug is filled, a nozzle 20 attached to the barrel, and a plunger 40 that pushes the drug filled in the barrel toward the nozzle. The barrel includes a flange 11, a body 12 continuous with the flange into which the plunger is inserted from the flange side, and a tip 13 continuous with the body on the opposite side of the flange. The body extends from the flange in a first direction. The tip extends from the body in a second direction and communicates with the body and the nozzle. The second direction is different from the first direction and is away from the flange. The nozzle extends from the tip in a second direction and is detachably attached to the tip.
