Reduced pressure therapy devices

Номер: US20120016325A1

Автор: Dean Hu, Kenton Fong, Moshe PINTO

Принадлежит: Leland Stanford Junior University

Described generally herein are tissue therapy devices, which may comprise a sealant layer and a suction apparatus. The sealant layer functions so as to create a sealed enclosure between it and the surface of a patient by forming, preferably, an airtight seal around an area of tissue that requires negative pressure therapy. The tissue therapy device may comprise a suction apparatus. The suction apparatus is typically in fluid communication with the sealant layer and functions so as to reduce the amount of pressure present underneath the sealant layer. The reduced pressure is self-created by the suction apparatus. Together the sealant layer and the suction apparatus preferably create a closed reduced pressure therapy system. Preferably, the pressure under the sealant layer is reduced by expanding the volume of the enclosure space and thereby decreasing the density of the air molecules under the sealant layer.

Sterile disposable remote pneumatic actuators

Номер: US20120029429A1

Автор: Jeffrey Alan KLEIN

Принадлежит: Individual

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 O 2 ignition/combustion associated with conventional electric switches in wet, hazardous or medical environments.

A suction retractor including an elongated tube that is operable to be inserted through a tubular retractor used in minimally invasive surgical procedures. One end of the tube is coupled to a handle having a chamber and the other end of the tube is coupled to a curved retractor portion, where the retractor portion allows the surgeon to hold back various anatomies during the surgical procedure. Thus, the suction retractor provides two functions that may otherwise require two different instruments. The retractor portion includes a series of parallel groves that allow liquids, such as blood, to flow along the retractor portion and into a suction port at the end of the tube. A suction device can be coupled to an outlet port in the handle that causes the blood and other surgical material to be sucked through the tube and out of the handle.

Vacuum therapy is an effective way to treat complex open wounds. Today, most of the equipment is very expensive to provide widespread use of this therapy and, most of them, are designed to in-patient use. Also, there are difficulties to obtain the needed materials in the same package for specific use of treating open wounds, which causes delay in the treatment. We designed a kit that is cost-effective and ready-to-use to be used with Jackson-Pratt or Portovac style suction drains that allows a cheap, out-patient alternative for use in open-wound situations. We devise that this system could be used in emergency situations where there is a hostile environment such as natural catastrophes, war and emergency situations, as well as to regular in and out-patient wound care.

Embodiments of the invention provide methods and devices for improved drainage systems and tubing. In one embodiment, a context-sensitive flow interrupter is provided that inhibits or facilitates flow of fluid when engaged with a mating holder. In another embodiment, outflow is optimized through control of the pressure in gas pockets in a tube, drainage tube or assembly. In one such embodiment, gas pockets are vented to inhibit excessive back-pressure or suction on an organ, vessel or cavity being drained. In another such embodiment, loops in the tubes are avoided by using a mechanical template in the form of a groove or peg assembly to thread the slack in the drainage tube to generate a monotonic gradient. In another embodiment, such as for active drainage systems, a bypass channel is provided that allows an applied vacuum to go around an obstruction created by the collection of fluid in an undrained dependent loop.

Systems, apparatuses, and methods for instilling fluid to a tissue site in a negative-pressure therapy environment are described. Illustrative embodiments may include a pneumatically-actuated instillation pump that can draw a solution from a solution source during a negative-pressure interval, and instill the solution to a dressing during a venting interval. A pneumatic actuator may be mechanically coupled to a disposable distribution system that can provide a fluid path between the solution source and a distribution component. A bacterial filter may be disposed in the fluid path between the actuator and the distribution component to prevent contamination of the actuator during operation. The distribution system may be separated from the actuator and disposed of after operation, and the actuator may be re-used. 116-. (canceled)17. A system for providing negative-pressure and instillation therapy , the system comprising:a negative-pressure source configured to provide a negative-pressure interval and a venting interval;an actuator comprising a pneumatic cylinder; anda distribution system comprising a dosing chamber, a fluid port configured to be fluidly coupled to the dosing chamber and to the negative-pressure source, and a fluid fitting configured to couple the pneumatic cylinder to the fluid port;wherein the actuator is configured to expand the dosing chamber during the negative-pressure interval and contract the dosing chamber during the venting interval.18. The system of claim 17 , wherein the distribution system comprises a bacterial filter between the fluid port and the fluid fitting.19. The system of claim 17 , wherein the distribution system comprises a constriction between the dosing chamber and the fluid port.20. The system of claim 17 , further comprising a solution source fluidly coupled to the dosing chamber.21. The system of claim 17 , wherein the distribution system further comprises:a first check valve fluidly coupled to the dosing chamber; anda ...
