  • Patent number: 7674247
    Abstract: An apparatus that includes two syringes, or a “double barrel syringe,” includes one syringe that injects or infuses while the other syringe aspirates. The double barrel syringe is a hand-held, hand-operated device with which injection and aspiration may be effected by a single action. The double barrel syringe may include a handle with two member. A first member includes one arm that pivotally couples to a plunger of a first syringe and another arm that pivotally couples to a barrel of a second syringe. A second member of the handle includes one arm that pivotally couples to a barrel of the first syringe and another arm that pivotally couples to a plunger of the second syringe. Methods for injecting or infusing simultaneously with aspirating are also disclosed.

  • Publication number: 20100049140
    Abstract: A method and apparatus for injecting fluid into areas having high density tissue that creates a high backpressure resistance on the injection device is disclosed. The high backpressure resistance is overcome through a mechanical advantage achieved by using a secondary reservoir having a cross-sectional area smaller than the cross-sectional area of a primary reservoir. Exemplary injection device reservoir housings may comprise a primary reservoir, a secondary reservoir, a check valve, a septum penetrating cannula, travel limits, a pen needle connecting portion, sliding seal guide ribs, a sliding seal, a pen needle assembly, a needle stop, and a patient needle.

  • Patent number: 7621887
    Abstract: An automatic medicament injector having a compartment for a dry medicament component and a compartment for a wet medicament component. The two compartments are separated by a seal structure that has a plug that is moved from a sealing position into a mixing position when the device is activated. The seal structure includes a wiper that scrapes the interior walls in the dry component compartment to prevent the dry component from accumulating at the seal/glass interface. A tapered insert “funnels” the mixed medicament components to an attached needle assembly, but can be removed when the device is filled. A filter is provided between the medicament compartments and the needle assembly. A chamber between the filter and the needle assembly allows for better flow through the filter. An actuation assembly drives the plug into the mixing position and forces the mixed medicament through the needle and into the user.

When lidocaine discharge from the tip of a hypodermic needle ends, the force f (N) required to discharge the hyaluronic acid solution from the needle tip suddenly increases, imparting sort of a jolt to the hand of the operator and creating a momentary sensation that the plunger is at rest. Letting the force f (N) required to discharge the lidocaine solution be P1 and the force f (N) required to discharge the hyaluronic acid solution be P2, the relationship therebetween is P1<P2.

  • Patent number: 7399295
    Abstract: A medical syringe employs a capsule containing multiple doses of medication within a sealed storage chamber formed between concentric inner and outer walls. The inner wall forms a cavity including a delivery chamber from which a single dose of medication is ejected. The syringe includes an ejection port, an axial moveable plunger extending into the cavity and delivery chamber, and a body with a compartment that holds the capsule. With the plunger in a first position, the capsule is closed. With the plunger in a second position, the delivery chamber is filled with a single dose of medication. With the plunger in a third position, the single dose of medication is ejected from the delivery chamber though the injection port.

  • Publication number: 20080154209
    Abstract: An apparatus that includes two syringes, or a “double barrel syringe,” includes one syringe that injects or infuses while the other syringe aspirates. The double barrel syringe is a hand-held, hand-operated device with which injection and aspiration may be effected by a single action. The double barrel syringe may include a handle with two member. A first member includes one arm that pivotally couples to a plunger of a first syringe and another arm that pivotally couples to a barrel of a second syringe. A second member of the handle includes one arm that pivotally couples to a barrel of the first syringe and another arm that pivotally couples to a plunger of the second syringe. Methods for injecting or infusing simultaneously with aspirating are also disclosed.

  • Publication number: 20080147014
    Abstract: The present invention is a fluid dispensing device particularly suited to medicine but also having many other applications. The user manually and selectively dispenses any of one or more fluids, typically a drug, contained within the device. Generally, the device comprises a frame that holds multiple hypodermic syringes and channels the dispensed fluids through a manifold. A flushing solution, for example a saline solution, enters the manifold, flows past each of the points where the syringes input into the manifold and continues to flow out of the device to a patient where the flushing solution and dispensed fluid are delivered to a patient.

  • Publication number: 20080103490
    Abstract: An apparatus includes a housing and a medicament container disposed within the housing. The medicament container includes a first plunger and a second plunger, each disposed therein. The medicament container has a first configuration and a second configuration. In the first configuration, the first plunger is disposed in a first position and the second plunger is disposed in a second position spaced apart from the first position by a first distance. Accordingly, a first portion is defined between the first plunger and the second plunger. A second portion is defined between the second plunger and a distal end of the medicament container. In the second configuration, the first plunger remains in the first position and the second plunger is disposed in a third position spaced apart from the first position by a second distance, such that a volume of the second portion is greater when the medicament container is in the second configuration than when in the first configuration.

  • Patent number: 7329235
    Abstract: A mixing syringe having a first sealed chamber containing a powder (powder housing) and a second sealed chamber containing a liquid (liquid housing). When the user needs to inject a patient, he or she holds the mixing syringe approximately upright and depresses a plunger. This motion causes a piercer to pierce a foil seal separating the two chambers. The liquid then drops down into the powder housing. The liquid flows through a passage in a piston located in the powder housing, where it then comes in contact with the powder itself. As the user continues pressing the plunger downward, the piercer comes to rest within the piston and seals the passage through the piston, thereby locking the piercer and piston together. The device is then ready for an injection. As the plunger is further depressed the piston expels the powder and liquid mixture through a needle.

  • Patent number: 7217254
    Abstract: A device for application of material to a surface, for example, biocompatible material to a tissue surface in a medical or clinical setting, is adapted to receive one or more biocompatible materials and one or more sources of pressurized medical gas, and to deliver these biocompatible materials via the medical gas(es) to a tissue surface or other surface. A regulation system controls flow of medical gas at a variety of pressures, and flow of biocompatible agent or agents, allowing agents to be sprayed or otherwise deployed onto a tissue surface. Switching apparatus operably connected to the regulation system directs a set of preset treatment positions allowing sequential application of biocompatible materials under various conditions in conjunction with an overall treatment protocol. The device can be used to apply a photoinitiating primer and polymeric sealant to a tissue surface, followed by light activation to form a polymer coating on the surface.
