摘要： A medication infusion device includes a medication container containing liquid medication; an infusion needle; and a reciprocating pump having a pump chamber. The liquid medication is withdrawn from the medication container into the pump chamber during suction operation of the reciprocating pump, and the liquid medication is dispensed out of the pump chamber through the infusion needle during dispensing operation of the reciprocating pump. There are also mechanisms preventing liquid from flowing through the infusion needle during suction operation of the reciprocating pump and preventing liquid from flowing back into the medication container during dispensing operation of the reciprocating pump. The medication infusion device may further include a microcontroller to control medication infusion volume and rate.

摘要： A positioning structure of a clamper of a threading machine for a racket contains: a rack, an engagement protrusion, an operation member, and two springs. A fixing holder is erected on a support plate of the threading machine, and the rack includes multiple first teeth, the fixing holder includes an accommodation chamber with an opening. The engagement protrusion is received in the accommodation chamber and includes a toothed extension on which multiple second teeth are formed. The engagement protrusion further includes a recess and an abutting fence. The operation member includes a drive portion and a push portion. The two springs are mounted on a top of the engagement protrusion, and two ends of each spring abut against the engagement protrusion and the fixing holder respectively so that each spring forces the engagement protrusion to engage with the rack.

摘要： The method set out herein involves conducting adaptive clinical trial to develop parenteral therapeutic product with variable dose drug delivery devices. The method comprises using a variable dose drug delivery device to respond modifications during the adaptive clinical trial, wherein the variable dose drug delivery device is able to deliver more than one dose level and is for delivering fluid formulation. Other methods set out herein involve using a variable dose drug delivery device equipped with radio frequency identification (RFID) or near field communication (NFC) technology to improve patient adherence to drug administration in the adaptive clinical trial.

摘要： A drug delivery device comprises a medication container containing medication for delivery and a detachable unit having an electronic circuit with a microprocessor. The electronic circuit is open and non-operational when the detachable component is assembled on the drug delivery device; and the electronic circuit is closed and operational when the detachable component is detached from the drug delivery device. The detachment of the detachable unit is an essential step to operate the drug delivery device. The detachable unit can be an activation protection cap or a needle shield remover for an autoinjector device. Alternatively, the detachable unit can be a needle shield remover for a pre-filled syringe.

摘要： A priming mechanism for operating an automatic injection apparatus to ensure medication contents are properly delivered prior to a needled syringe of the apparatus being injected. The priming mechanism includes a push rod to move plunger(s) within the syringe; a releasable support including bendable supporting arms, which limiting motion of the syringe relative to an upper housing body before and during priming; and a recess element inside the lower housing body to release said bendable arm to allow motion of the syringe relative to the upper housing body in distal direction after priming. In one form, the priming mechanism is used for removing air bubble before injection to ensure delivering correct dose. In another form, the priming mechanism is used to mix different contents in a dual chamber syringe before injection.
