  • Patent number: 11191887
    Abstract: A bodily fluid collection system includes a reduced pressure treatment unit for providing reduced pressure to a fluid collection system through a canister having a container with an inlet adapted to be fluidly coupled to the fluid collection system, an outlet adapted to be connected to a source of reduced pressure, and an absorptive lamination disposed within the container. The absorptive lamination may be formed from a plurality of absorptive layers and wicking layers interleaved between the absorptive layers that collectively manifold bodily fluids from a tissue site into and throughout the absorptive lamination to trap and collect the bodily fluids. The container expands as the absorptive lamination swells with the bodily fluid being collected.

  • Patent number: 9384925
    Abstract: The various embodiments of the present invention relate to remote pneumatic (bellows-action) actuators for switching applications, which are preferably sterile and/or disposable. When compressed, the bellows-action actuator provides a pulse of air pressure sufficient to actuate a remotely-located pneumatic switch configured to turn on/off an electrical, mechanical or optical device. The pulse of air pressure is propagated along a non-conducting tube, thereby substantially reducing the risk of e.g., electric shock or O2 ignition/combustion associated with conventional electric switches in wet, hazardous or medical environments.

  • Patent number: 8480656
    Abstract: A dispensing device for dispensing medicaments to a patient that is made up of first and second stand-alone, interconnectable assemblies. The first of these assemblies comprises a fluid reservoir assembly that houses a fluid reservoir defining component while the second assembly comprises a fluid delivery and control assembly that includes a novel flow control means that functions to control the flow of medicinal fluid from the fluid reservoir of the first assembly toward the patient via a plurality of fluid flow control passageways. Because the stand-alone fluid delivery and control assembly is initially totally separate from the fluid reservoir assembly of the apparatus, the fluid flow passageways of the fluid delivery and control assembly can be effectively sterilized using conventional gamma ray sterilization techniques without adversely affecting the medicament contained within the fluid reservoir of the apparatus.

  • Patent number: 6824528
    Abstract: A method and apparatus for pressure infusion and temperature control of infused liquids includes a receptacle for receiving a liquid-filled bag containing intravenous solution or other liquid and an inflatable pressure device. The inflatable pressure device is disposed within a pressure device bag and is positioned proximate the liquid-filled bag in the receptacle. The inflatable pressure device expands within the pressure device bag upon inflation and exerts pressure on the liquid-filled bag. A heating element may be disposed on the inflatable pressure device bag to heat the liquid-filled bag to a desired temperature. The liquid may alternatively be maintained at a desired temperature, while flowing to a patient via a heating assembly disposed along a tube. The heating assembly includes a sleeve having a slot for receiving the tube and a plurality of individually controlled heaters.

  • Patent number: 6800069
    Abstract: The present invention is directed to a modular pressure infuser apparatus adapted to allow a user to modify the configuration of the pressure infuser apparatus by utilizing one or more interchangeable manual and/or automatic pumps to inflate a pressure infuser bag of the pressure infuser apparatus. The modular configuration of the pressure infuser apparatus permits the user to detach and reattach a motorized pump and/or a manual pump to the pressure infuser bag quickly, easily, and efficiently without decreasing the air pressure of the pressure infuser bag. By providing selectively removable pump modules, the user can select the configuration of the pressure infuser apparatus that is best adapted to the needs of the patient. A pressure release valve is configured to regulate the pressure of the pressure infuser bag.

  • Patent number: 6565532
    Abstract: An array of microneedles is provided to apply semi-permanent or permanent markings to skin, or to apply semi-permanent subcutaneous makeup or other cosmetic compounds to skin. The microneedles can apply identifications or other tattoo-like graphics, and will not enter into the dermal layer of the skin so that the application procedure is painless. The microneedle array is also useful for delivering specific compounds or actives into the skin, such as cosmetic compounds or nutrients, or various skin structure modifiers that can be delivered subcutaneously without having to visit a cosmetic surgery clinic.

  • Patent number: 6485461
    Abstract: A disposable device is provided which accurately and reliably delivers an infusable liquid to a patient. The infusion device includes a housing which defines a bladder chamber. A compressible bladder is disposed in the bladder chamber and is compressed by the housing upon filling the bladder with an infusable liquid to create a pressurized bladder. The infusion devices further includes a delivery system for subcutaneously delivering the infusable liquid to a body. The delivery system includes a collapsible member that supports an injection needle and a cannula. The injection needle is used to insert the cannula into the skin of the body being treated. The cannula is in communication with the bladder during delivery of the infusable liquid. The housing includes microfluidic passageways that allow communication between fluid in the bladder and the cannula.

  • Patent number: 6379341
    Abstract: A syringe for vaginal irrigation is disclosed. This syringe is easily and effectively used for irrigating monstrous secretions from the vagina particularly during or after a menstruation, thus removing monstrous odor from the vagina and allowing the user to feel refreshed at the vagina in addition to keeping the vagina clean and sanitary. The syringe is comprised of an elastic barrel containing a vaginal irrigating solution, an L-shaped elbow pipe engaging with the externally-threaded mouth of the barrel, and a hollow vaginal insert engaging with the elbow pipe through a screw type engagement. This vaginal insert has a linear and tapered profile with the outside diameter of the insert being gradually reduced in a direction from its end around the elbow pipe to its distal end.

  • Publication number: 20010031947
    Abstract: The present disclosure describes a system wherein a drug or other fluid to be delivered to a specific desired location within the body is stored in a reservoir that is directly displaced by a force to infuse the drug from the device into the patient. Several specific methods are used to displace the reservoir, including, generally, hydraulic displacement, mechanical screw-type displacement, and spring force displacement of the fluid reservoir.

  • Patent number: 6283944
    Abstract: An infusion system delivers drug to the patient at a fixed rate while permitting the patient to introduce a controlled bolus dosage when needed. A pump having a bulkhead that is provided with first and second flow paths from the pump reservoir to a single outlet port. The first flow path communicates with a first flow regulator which restricts flow in the first flow path to the desired fixed rate of delivery. The second flow path communicates with a patient-operated pump incorporated into the pump housing. The patient-operated pump may be in the form of a deformable reservoir that accumulates a drug bolus which may be expelled when the reservoir is compressed by the patient's fingers. A second flow regulator may be incorporated in the drug flow path upstream of the patient-operated pumping device to restrict the dosage that may accumulate therein. Additionally, a fluid control assembly incorporating a patient-controlled pump may be used with single or dual port pumps.

  • Patent number: 6258063
    Abstract: A hypodermic injection system allows for the generation of a high pressure liquid jet capable of passing through the skin. The system uses two regions, the first region being flexible or squeezable and the second region having at least one exiting orifice through which the liquid jet can be expelled. The flexible region can be deformed by a pressure change in the surrounding container generated by an activatable gas generator that generates pressure within the first region that causes the liquid to be expelled.
