403 results about "Medication injection" patented technology

Medications given using a subcutaneous injection. Medications administered by subcutaneous injection include drugs that can be given in small volumes (usually less than 1 mL but up to 2 mL is safe). Insulin and some hormones are commonly administered as subcutaneous injections.

Safe intravenous infusion port injectors

We describe connectors for safely and conveniently injecting measured doses of sterile liquid medications into a patient via one or more infusion ports in intravenous access assemblies. Each connector comprises a tubular injector divided by a rigid septum which holds a hollow needle sharp on each end safely recessed in a leading and in a trailing chamber. The leading chamber snugly holds the trailing limb and penetrable cap of an inserted standard infusion port. The trailing recess snugly holds the leading end of a cartridge with a leading penetrable diaphragm, a bore containing liquid medication, a cartridge piston and trailing bore suitable for insertion of a separate cartridge plunger having markers for measuring doses delivered; or, alternatively, the pentrable cap and trailing limb of second similar infusion port attached by trailing tubing to a large measured volume infusion source. When assembled such that the trailing cap of infusion port is penetrated by the needle in the leading chamber and the leading diaphragm of the cartridge or, alternatively, the leading penetrable cap on a second infusion port is penetrated by the needle in the trailing chamber, such that flow can proceed through the needle, precisely measured doses of sterile liquid medication can be injected into the venous access assembly without possibilities for the user to touch, get stuck or finger-contaminate the needle or its contents. Unique features added to increase the efficiency of the system are a biased leading end on the tubular injector to conveniently and securely accommodate a Y-infusion port; an eccentric needle in the connector, such that rotation prevents the leading sharp end of the needle from passing through the infusion port cap via the same track; and an easily removed biased cap for keeping the cartridge diaphragm sterile.

Medicament administration apparatus

An apparatus for removal of premixed drugs or reconstitution of lyophilized drugs and for the injection of the reconstituted drug into the patient. The apparatus includes a syringe assembly and an adapter assembly that can be removably connected to a medicament container containing a premixed drug or lyophilized medicament. The syringe assembly of the apparatus includes a body portion to form a liquid chamber between the forward end of the body portion and the piston and a syringe cannula assembly. The syringe cannula assembly, which can be removably interconnected with the body portion, comprises a cannula support and a hypodermic needle sealably connected to the cannula support. The adapter assembly comprises an adapter preferably molded from a moldable plastic that includes a top wall, an adapter cannula connected to and extending from the top wall and a variety of connectors connected to the top wall for removably interconnecting the adapter with the medicament container. The adapter assembly further includes syringe connector member connected to the top wall for removably interconnecting the syringe with the adapter in a manner to uniquely position the syringe cannula within the lumen of the adapter cannula wherein it is completely shielded from external contamination to prevent print damage and injury to the user.

Injection-purpose medicine composition for improving stability of ligustrazine medicine injection formulation and preparation method of injection-purpose medicine composition

The invention discloses an injection-purpose medicine composition for improving stability of ligustrazine medicine injection formulation and a preparation method of the injection-purpose medicine composition. The injection-purpose medicine composition is prepared by the method comprising following steps: dissolving ligustrazine salt in water for injection, adjusting the pH value of the liquid medicine by adding citric acid and / or sodium citrate used as a pH regulator, wherein the dosage of the citric acid and / or sodium citrate ranges from (0.1mg to 200.0mg) / 100ml. In the invention, pH value of the injection liquid can be more stable, the content of ligustrazine degradation substance is greatly reduced compared with that of the prior art, the clarity of the ligustrazine injection liquid is improved under the condition of not using other cosolvents to increase the clinical application risk, particularly, the problems of small white spots, white blocks and solution turbidity are solved under the condition that the ligustrazine injection liquid is stored for a long time by adopting the prior art, and the medicine composition ensures that the inspection of visible foreign substances of the product is in accordance to the formulation of medicine quality standard, and is convenient for clinical medication and popularization.

Method for providing medicament to tissue

A system for delivering medicaments to tissue including a delivery member and an optical fiber formed together into a unitary structure. The optical fiber has an inlet attached to a laser energy source and an outlet for emitting laser energy. The delivery member has an inlet attached to a medicament source and an outlet for injecting medicament. A handpiece is adapted to receive the ablating and injecting device in a controlled and movable relationship and may include at least one tissue stabilizing member thereon. In use, the distal end of the handpiece is placed against tissue to be ablated. The optical fiber is advanced into the tissue while emitting laser energy thereby ablating the tissue and forming a channel therein. During retraction, medicament may be injected into the channel or into the tissue surrounding the channel.
