A system is disclosed for recovering autologous thrombin from a blood product. The blood product is drawn into an injecting syringe and a clot is allowed to form. A discharge port of the injecting syringe is communicably connected to an intake port of an aspirating syringe through a hydrophilic filter assembly. The injecting and aspirating syringes are simultaneously operated to transmit blood product through the filter such that fibrous clotting material and red blood cells are removed by the filter and a concentrated, high-quality thrombin solution is recovered.

Medical device assemblies capable of aspirating liquid into a syringe barrel or other medical devices while evacuating any air from the syringe are described. An exemplary medical device includes a syringe barrel, plunger rod and stopper assembly having an air permeable and liquid impermeable porous portion and structure for forming a vacuum within either the stopper or the plunger rod. Described is a medical device including a syringe barrel, plunger rod and stopper assembly having an air permeable and liquid impermeable porous portion and structure for forming a vacuum within chamber between the stopper and plunger rod wherein the plunger rod includes a sealing edge and is moveable relative to the stopper. Exemplary medical devices may include a vent for allowing air that permeates through the porous portion to escape to atmosphere. Methods for aspirating a syringe barrel with a liquid are also provided.

Apparatus and methods for medicament delivery. The apparatus may include, and the methods may involve, a delivery device for delivering a target amount of the medicament from a distal end of the device. The device may include a rod for moving a plunger that discharges the medicament from the distal end. The device may avoid or reduce deformation of the plunger during the discharge. The plunger motion may be stopped by detent that interacts with the rod. The apparatus and the methods may provide an operator indication of progress of stages of operation. The device may feature triggers corresponding to stages of medicament displacement from the device, such as pre-delivery stages, including priming.

An apparatus including a hollow body, an inlet fluidly coupled to the hollow body, a piston slidably engaged within the hollow body, and a filter module arranged within the hollow body between the inlet and piston. The piston and hollow body cooperatively generate a negative pressure, relative to ambient, within the hollow body during distal piston translation from a first position to a second position, thereby drawing a fluid, such as blood, through the filter module into the hollow body. The piston and hollow body cooperatively generate a positive pressure, relative to ambient, within the hollow body during piston translation from the second position to the first position to egress the filtered fluid from the hollow body. The filter module may include a filter housing, a filter medium disposed within the housing, and a body valve configured to seal an open distal face of the filter housing.

A delivery device (10, 40, 100) for delivering a substance, such as an insulin formulation, to a patient includes a storage container (12, 112) containing the insulin formulation, a delivery member (20, 42) connected to the storage container by a fluid pathway for injecting the insulin formulation into the patient for delivering the insulin formulation to the patient at a controlled basal flow rate or bolus flow. The delivery device can have a pump mechanism for delivering the substance to the patient. An activated charcoal adsorbent (51 57, 87) or activated carbon is positioned in the fluid pathway between the storage container and the delivery member for removing at least a portion of a phenolic stabilizing agent from the insulin formulation before delivering to the patient. A method of delivering an insulin formulation to a patient includes the step of contacting the insulin formulation with an activated charcoal or activated carbon adsorbent to remove at least a portion of a phenolic stabilizing agent from the insulin formulation before introducing the treated insulin formulation to the patient.

The present invention relates to an enteral syringe including a barrel with a first inlet, a first outlet positioned opposite the first inlet, a first side opening formed in a side of the barrel and a plunger movably mounted in the barrel where the barrel can be filled and refilled with enteral fluid without removing the plunger from the barrel.

Injector for use in ophthalmic applications, having a gas supply tube and a liquid supply tube, both supply tubes being interconnected at a junction member that is in fluid communication with an outflow cannula, characterised in that a selective flow member is placed in the gas supply tube, near the junction member, allowing gases to pass through and blocking the passage of liquid.

A filtering needle assembly for use in administering a liquid payload, including: a needle and connector portion; a filtering needle body cap; a seal plug, and a filter: The seal plug initially lacking a needle channel so that a distal end of a hollow needle must be forced through the distal end of the seal plug while the seal plug is retained by a holding tool with a hollow midline of adequate depth to receive the protruding end of the hollow needle. An attempt to reuse the filtering needle assembly with a second insertion of a hollow needle into the filtering needle assembly will not work as the distal end of the hollow needle will push the seal plug distally rather than traverse the seal plug.
