Systems and methods for gas mixing in ocular surgical equipment
A gas mixing system for providing mixed gas for intraocular injection. In some embodiments, a first fixed-volume chamber is automatically purged and filled with gas from a first gas supply input, to a first predetermined pressure. A second fixed-volume chamber is purged and filled with gas from a second gas supply input, to a second predetermined pressure. The first and second predetermined pressures are determined based on a desired concentration of gases in the final mix, and the respective volumes of the first and second fixed-volume chambers and of a third fixed-volume chamber. Gas from the first fixed-volume chamber is then allowed to mix with gas in the third fixed-volume chamber, which was previously purged. Next, gas from the second fixed-volume chamber is allowed to mix with gas in the third fixed-volume chamber. Finally, the mixture of gases in the third fixed-volume chamber is expressed into an intraocular syringe.
Apparatus and method for aseptically filling pharmaceutical containers with a pharmaceutical fluid using rotary stage
Systems and methods for aseptically filling pharmaceutical containers with pharmaceutical fluid are disclosed. In one general aspect, these are based on an aseptically sealable chamber that includes a transfer wall to which pre-sealed pharmaceutical source and receiving containers are mounted aseptically. A robotic arm and a syringe store are disposed within the chamber along with a sterilizing facility for establishing in the chamber an aseptic condition. The robotic arm can grip and operate syringes to inject and/or extract pharmaceutical products from the containers by piercing their closures with the needles of the syringes.
Device for subcutaneous delivery of fluid medicament
An improved device delivers a fluid medicament to the subcutaneous tissue of a user. The device is better suited for patients with Parkinson's Disease and other central nervous system disorders, than conventional infusion devices. The device can include a reusable part including a drive component (e.g., motor) and control electronics and a disposable part including a medicament reservoir. Medicament can be evacuated from the medicament reservoir by a plunger assembly that includes a plunger attached to a lead screw that is rotated by a nut, all within the disposable part. The device can be fluidically coupled with the tissue via a flexible cannula. Various embodiments relate to an improved cannula insertion mechanism that delivers the cannula under a force applied by a spring. Various embodiments relate to improved filling of the device, for example, using a vial adapter and an automated filling station.
Shielded syringe holding device for filling a syringe with a radioactive solution
Syringe shield for using a syringe that includes a barrel, a tip and a plunger when manipulating a radioactive solution. The syringe shield includes: a shield body in which the syringe is insertable, the shield body having a window; a first flange at a first open end of the syringe shield; a second flange at a second open end of the syringe shield; wherein the second flange, the shield body, and the window include radiation shielding material, and wherein the tip of the syringe is accessible by the second open end of the syringe shield and the plunger extends outside the first open end when the syringe is inserted in the syringe shield.
Medical syringe system with filtered filling port
A syringe system includes a syringe and a filtration device connected to the syringe for sterilizing and introducing fluid into the syringe. The syringe includes a syringe barrel having a proximal end defining a barrel opening, a distal end defining a delivery opening, a bore extending between the proximal end and the distal end, and a stopper disposed in the bore of the syringe barrel. The filtration device has an inlet and an outlet coupled in fluid communication with the delivery opening at the distal end of the syringe barrel. The filtration device includes a stem and a filter membrane disposed in line with the stem. The filter membrane optionally has a plurality of pores each with a nominal pore size in a range of approximately 0.1 μm to approximately 0.5 μm such that a pharmaceutical fluid can be introduced as a sterilized pharmaceutical fluid into the bore of the syringe barrel by passing through the filtration device.
NEEDLELESS INJECTORS AND RELATED METHODS
A needleless injector for performing a subcutaneous injection without a needle. The needleless injector has a drive end having a drive spring for driving a piston system against a plunger to push liquid out a nozzle of an ampoule with sufficient velocity to deliver a subcutaneous injection without a needle.
Syringe for administering foam
Syringes which are suitable for dispensing and injecting medical foams for sclerotherapy are described and claimed. The syringes of the invention comprise a syringe barrel having a nozzle and a bore to receive a syringe plunger; a syringe plunger defined by a front end and a rear end connected by a tubular walls and having an internal hollow duct between the front end and the rear end, and through which foam can flow; and an injectate chamber formed by insertion of the front end of the plunger into the barrel. The syringes comprise a flow-disruptor arranged to modify the flow of foam as it enters the injectate chamber. In certain embodiments the syringes comprise waste chambers which capture and retain poor quality foam. The syringes are particularly useful for dispensing foams made with little or no nitrogen content and are configured to reduce the risk of air contamination during dispensing the foam. Kits comprising the syringes together with a suitable source of foam and methods of dispensing foam form further aspects of the invention.
Container adapter, delivery assembly and method of delivering a liquid to a patient
A container adapter for a medical delivery device is disclosed. The medical delivery device has a container seat for holding a container, a dosage chamber, a dosing mechanism and a lock mechanism adapted to prevent operation of the dosing mechanism when no container is held in the container seat and to allow operation of the dosing mechanism when the container is held in the container seat. The container adapter includes an adapter container seat arranged to hold a container, a joint structure arranged to be detachably positioned in the container seat of the medical delivery device and to connect the adapter container seat to the dosing mechanism, and an unlock member adapted to activate the lock mechanism. A delivery assembly and a method of delivering a liquid to a patient from different containers is also disclosed.
Apparatus, system and method for fluid delivery
A filling aid. The filling aid includes a needle housing portion including at least one tab having a starting position and a filling position, and a filling needle cradle including a filling needle, the filling needle cradle slidable connected to the needle housing portion and having a starting position and a filling position, wherein when the at least one tab on the needle housing moves from a starting position to a filling position, the filling needle cradle slides from a starting position to a filling position, and wherein when the at least one tab on the needle housing moves from a filling position to a starting position, the filling needle cradle slides from a filling position to a starting position.
AUTOMATED SYRINGE FILLING AND MEASURING SYSTEM AND METHODS OF USING SAME
Methods and devices are provided precision filling of medical syringes. Generally, the methods and devices are designed to determine and measure dosages and fill a syringe with a precise amount from a medication vial and to store or transmit to a medical records storage system data associated with the process. In one embodiment, the fill apparatus weighs, photographs and stores information on a syringe and medicine vial, fills the syringe from the vial and confirms transfer of the medicine to the syringe from the vial.
