  • Patent number: 10064651
    Abstract: An embodiment of a uterine hemorrhage controlling system comprises a suction module including a suction end coupleable to a pump by a connecting tube, and a sealing module coupled to the suction module. The system may further comprise the pump and a filter coupled to the suction module. A uterine hemorrhage controlling method comprises: shielding a suction module that has been delivered into a uterus; sealing an entrance into the uterus while the suction module is situated within the uterus; applying a negative pressure within the uterus upon activation of a pump; and maintaining the negative pressure within the uterus to induce uterine contraction. The method may further comprise delivering the suction module into the uterus; transmitting bodily fluids, out of the uterus through the suction module, and filtering the bodily fluids.

  • Patent number: 8622976
    Abstract: Systems and methods for infusion of fluids using stored potential energy and a variable flow resistor. In one aspect of the present disclosure, there is provided an infusion device that includes a plunger situated within a vessel so as to define a chamber within which a volume of fluid can be accommodated between a downstream surface of the plunger and the vessel. The infusion device further includes an outflow path through which the fluid in the chamber can be dispensed upon displacement of the plunger by a force acting thereon. A variable flow resistor is situated within the outflow path and is configured to allow a substantially constant fluid flow rate from the vessel to be maintained as the force acting on the plunger decreases.

  • Patent number: 8118780
    Abstract: A hand-held remote for a medical fluid injector includes a syringe and a conduit which may be coupled to a pressure transducer on a control circuit of the injector. Movement of a plunger within a syringe body on the syringe creates a pressure which is sensed by the pressure transducer and the control circuit responds to the sensed pressure by causing fluid to be ejected from, or drawn into, a syringe mounted to the injector. The pressure developed by the remote provides tactile feedback to an operator for improved control over injections.

  • Patent number: 7819845
    Abstract: A syringe plunger/jacket assembly may comprise a flexible jacket attached to a rigid plunger. The jacket may comprise at least two sealing rings (front and rear) that prevent fluid from leaking out of the rear of the barrel during injection of fluid from the syringe. The rear sealing ring may or may not contact or seal the interior surface of the syringe barrel in an unloaded state. In the loaded state, when force is applied in the direction of the forward discharge end of the syringe, pressure is created on the jacket. This condition causes the rear seal to expand and contact and/or seal the interior surface of the syringe barrel.

  • Patent number: 6605064
    Abstract: Disclosed is a single-use syringe comprising a needle housing, a bore-containing fluid-delivery needle and a volume-containing element. The needle housing has a top surface to which the volume-containing element is attached, a needle attachment side to which the bore-containing needle is attached, and a fluid delivery channel in communication between the top surface and the needle attachment side. The volume-containing element is fluid-tight but for communication with the fluid-delivery and a filling port. Embodiments are disclosed which include vapor-permeable portions which facilitate lyophilization of materials in situ.

  • Patent number: 6080461
    Abstract: Solid disks of polyethylene oxide are radiation crosslinked to instill viscoelastic memory. The disks are then pierced with a needle, heated, cooled and the needle removed to form disks containing a flow orifice in each which upon contact with water will revert to solid disks. A disk with a flow orifice made as just described when used as a memory flow control valve in a conventional injection device will produce a syringe with a single-use, auto-destruct capability. When the disk is inserted in a retainer in the flow channel of the injection device, a drug/vaccine can be drawn into the syringe and then expelled for a preselected time less than six minutes before the water in the drug/vaccine causes the flow orifice in the disk to close, the disk then reverting to its solid shape due to its viscoelastic memory.

  • Patent number: 5879336
    Abstract: The invention relates to a portable and non-implantable device to enable a patient to self-administer, on demand, successive doses of a liquid while ensuring that the period of time between two successive administrations cannot be less than a reference value. The device has a liquid reservoir formed in a piston which can be pushed in a chamber to expel the contents of the chamber via an injection outlet and which is returned in the opposite direction by a return. The liquid reservoir communicates with the inside of the chamber via a passage formed through the piston and is provided with a flow rate limiter so that the time required to fill the chamber corresponds to a reference value. The invention is suitable for medical applications.

  • Patent number: 5290258
    Abstract: This syringe for dispensing multiple doses of a liquid medicament one at a time has a cylindrical barrel for containing the medicament. At one end of the barrel is a single outlet opening. A plunger in the barrel discharges the medicament. A syringe cap rotatable mounted on the barrel has guide means restraining the cap against axial movement. Ratchet means on the cap and barrel permit only unidirectional rotation of the cap and sequentially retain the cap in equally spaced detent positions on the barrel. Nozzles on top of the cap have passages for ejecting the medicament. Each passage terminates in a hole in the top of the cap. Only one nozzle at a time communicates with the barrel vis the outlet opening in each detent position of the cap on the barrel.

  • Patent number: 5067942
    Abstract: A single use needle assembly includes a needle extending through a base with a hub extending from the base for engaging a syringe. The end of the needle within the hub has a port which is covered by a retractable sheath. When the needle assembly and a syringe are assembled, two separable tabs held within a basket force the sheath to retract and expose the port in the needle whereby a fluid can flow through the needle. Upon disassembly of the needle syringe, the tabs separate from the basket and are effectively destroyed for further use in retracting the sheath.
