Closure Or Barrier Between Compartments Moved To Permit Mixing Patents (Class 604/89)
  • Patent number: 10632261
    Abstract: A self-admixing disposable hypodermic needle (admixing needle) includes a reservoir containing an additive, such as a buffering agent, to facilitate homogeneous mixing of the additive with an injection fluid, such as Lidocaine, contained in a cartridge held within a mechanically conjoined syringe. The admixing needle establishes a fluid communication pathway for hypodermically delivering the injection mixture to a patient preceding a potentially painful dental or medical procedure. Prior to removal, a delivery needle cap is pushed toward the syringe to dispense the additive into the cartridge. The delivery needle is then placed within the patient's tissues and the syringe is operated to force the injection mixture from the cartridge. Mixing surfaces on the male body (reservoir plunger) and the female body (reservoir) and other mechanical features homogeneously combine the injection fluid with the additive as the injection mixture travels through the admixing needle during the hypodermic injection.

  • Patent number: 10583257
    Abstract: A method and apparatus for use in controlling a dispensing rate of medication or other substance via a syringe, including, without limitation, into a patient, intravenous line port or heparin lock. A force (typically manual) is applied to an input plunger of a dashpot, which is directly coupled to a piston which, in turn, is coupled to an output plunger. The force applied to the input plunger is buffered and transmitted to the output plunger. The output plunger acts upon the plunger of a conventional syringe, thereby resulting in flow of medicine or any other substance from the syringe at a desired and controlled flow rate.

  • Patent number: 10543315
    Abstract: Described are multi-chambered vessels comprising a first chamber, a second chamber, and a seal comprising a first member and a second member, wherein the first and second members are engageable with one another to form a barrier separating the first and second chambers. The first and second members are disengageable from one another to open a channel between the first chamber and second chambers. The vessels allow communication between the first and second chambers at a desired time, for example in order to contact components contained within the chambers or in order to sequentially release components or doses of components from the vessel. Also provided is a kit comprising a seal of the invention. The kit allows a single-chambered vessel to be converted into a multi-chambered vessel capable of controlling communication between the chambers at the final stage of the filling process.

The mixing device comprises concentric outer and inner barrels that form an outer chamber, the inner barrel having an inner chamber. A mixing plunger is slidably located in the outer chamber. A seal located in the outer chamber is capable of axial movement, in response to depression of the mixing plunger, from a first position in sealing engagement with one or more apertures in the inner barrel to a second position intermediate the apertures and vents in the outer barrel. This allows depression of the mixing plunger to force a first substance from the outer chamber through the apertures to mix with a second substance in the inner chamber. The mixed substance in the inner barrel is then delivered by the syringe with subsequent needle retraction.

    Abstract: A movable mixing disc may be utilized in connection with a syringe. The mixing disc may comprise a hole which may be covered by a fine screen or coupled to a porous member, allowing only certain elements of a solution to pass through the mixing disc. Actuation of a plunger of the syringe may cause liquid to emerge from the mixing disc hole as a high velocity jet or other turbulent flow, stirring up any settled particles on a distal side of the mixing disc. As the ejection continues, the mixing disc may be pushed forward by the plunger in order to eliminate any unused volume. Also, the mixing disc may be moved forward by virtue of a pressure difference created by a pressure drop across the mixing disc, such as a pressure drop created as the plunger is displaced to induce fluid flow across the mixing disc.

  • Patent number: 9561329
    Abstract: Disclosed are a piston for a micro-volume syringe and a plunger. The micro-volume syringe has a syringe barrel with a space defined in it. The piston is slidable on and along a wall of the space. A leading member to be arranged on a side where the piston comes into contact with a solution filled in the space and a trailing member to be arranged on a side where a plunger rod is to be connected, the latter side being opposite to a solution side of the leading member, have been integrated with each other. The trailing member has a higher hardness than the leading member. With the micro-volume syringe in which a drug solution can be filled in a very small quantity, the piston makes it possible to perform smooth drawing and ejection of the drug solution without leakage. Even if the small piston connected to a tip of the plunger rod is operated in a direction that the piston is to be pulled out of the syringe, the plunger rod does not slip off from the piston accidentally.

    Abstract: Methods and apparatus are disclosed for disposing a valve within a barrel of a conventional syringe to provide, first, a mixing syringe embodiment and, second, a sequential delivery syringe embodiment. Generally, the valve divides the syringe barrel into a proximal and a distal chamber. When used for mixing, the valve is self-displaceable by expansion of decompressing matter disposed within the valve against exterior matter permitting proximal displacement of the valve independent of character of matter in the distal chamber. For sequential delivery, switching of the valve occurs after switch opening causing pressure is relieved, thereby reducing inadvertent uncontrolled flow when the valve opens. In addition, a combination mixing and flush syringe is disclosed whereby a mixing and a flush capability is provided within a conventional syringe.

  • Patent number: 8905975
    Abstract: The present invention relates to a container comprising: a body; a pusher movable with respect to the body between an initial position and an end-of-use position; a locker located on the pusher and forming an abutment so as to be able to abut against the body between the initial position and the end-of-use position, wherein, the abutment abuts against the body to limit distal movement of the pusher relative to the body to a pusher locking position located between the initial position and the end-of-use position; a locking arrangement capable of, temporarily, locking the locker on the pusher so as to define a locker locking position of the locker on the pusher, the locker locking position establishing the position of the abutment relative to the pusher so as to set the pusher locking position; and, an unlocking arrangement designed so that, with triggering, the locking arrangement is released so as to allow the locker to be displaced relative to the pusher and for the pusher to be moved past the pusher locking

  • Patent number: 8900206
    Abstract: Disclosed herein is a fluid infusion device of the type that delivers medication fluid to the body of a patient. The device includes or cooperates with a fluid reservoir, and the device has a sealing assembly to receive and form a fluid seal with the fluid reservoir. A retractable sealing element surrounding a hollow fluid delivery needle may be used to seal a port of the fluid reservoir. The port may include a pressure vent that is sealed by the retractable sealing element. In one variation, the reservoir includes a moving valve sleeve that holds a septum. The septum moves to allow the reservoir to vent, and to form a seal with the port when the needle pierces the septum. In another variation, the device includes a needleless sealing assembly. In yet other variations, the device uses a needled fluid reservoir.
