Prevention of ventilator associated pneumonia (vap)

Номер: US20120006331A1
Автор: Bruce D. Spiess, Cindy Munro, Curtis N. Sessler, Kevin R. Ward, Laurence J. Dinardo, Mary Jo Grap, Rao R. Ivatury
Принадлежит: Virginia Commonwealth University

Ventilator associated pneumonia (VAP) may be prevented in a patient, or its occurrence reduced in a population of patients, by using an anti-VAP device or an anti-VAP material such as an anti-VAP mouthpiece that absorbs secretions. By reducing the problem of bacterial-containing secretions that otherwise build up in the airway of, and elsewhere in, the intubated patient, VAP can be prevented from occurring in intubated patients, such as patients intubated with an endotracheal tube (ETT) or a nasogastric tube. Anti-VAP mouthpieces also are useable in non-intubated patients to maintain oral hygiene.

Medical tubing stabilizer

Номер: US20120016310A1
Автор: Barbara R. Holliday
Принадлежит: Individual

In various embodiments of the invention, a system and dynamic device are provided to create stability of tube placement in medical and other applications. The described systems and principles also apply in other environments outside of medicine and healthcare. The described medical tubing stabilizer adheres to the tubing itself providing handles or anchors to prevent stitch slippage and to prevent the tubing from falling out in any situation that requires a semi or permanent tubing placement. The device also aides in stabilizing the tubing in the wound site, and thus maximizes placement in its intended area of effect (e.g., in the body cavity, in a medical context). These stabilizing effects substantially minimize slippage of stitching holding the tubing in place to prevent the tubing from falling out or becoming dislodged or displace, thus preventing irritation and damage to the skin around the wound site, infection, seroma, edema and morbidity in a medical context.

Liquid medicine injection amount adjusting method, liquid medicine injection amount adjusting apparatus, and liquid medicine injecting system

Номер: US20120116348A1
Автор: Seiichi Katoh, Yasuhiro Kawamura
Принадлежит: Seiichi Katoh, Yasuhiro Kawamura

In a liquid medicine injecting system, an open route is formed in which a liquid medicine flows from a container that contains the liquid medicine to a blood vessel of a biological body via a micro-pump, a flow volume sensor, and a tube. A back pressure from the biological body directly operates against the micro-pump via the open route. When the flow volume of the liquid medicine is constant, power of the micro-pump has a constant relationship with the back pressure. The flow volume of the liquid medicine is adjusted to be a target volume by controlling the power of the micro-pump, and the power of the micro-motor is monitored. An abnormal injecting state of the liquid medicine caused by such as pulling out of an injection needle from the biological body is immediately detected with high accuracy based on the monitored result of the power of the micro-pump.

The invention concerns a flow regulator, made of a stack of 3 plates, respectively a top plate including a flexible membrane ( 1 ), a middle plate ( 2 ) with pillars and through holes and a bottom plate ( 3 ) with fluidic ports, micro channels and through holes ( 8,9,12 ). The principle is based on the deformation of the membrane due to the pressure of the liquid. The membrane goes in contact with the pillars of the middle plate, obstructing gradually the through holes of the pillars. The device is designed to keep the flow constant in a predefined range of pressure. The device is dedicated to ultra low flow rate up to 1 ml per day or below, typically for drug infusion. Plastic flow regulators comprise preferably several independent valves coupled in parallel. The membrane plate is therefore made of several flexible membranes obstructing gradually the flow by increasing the pressure. Stress limiters are used to avoid plastic deformation of the membrane. For implanted pump, the use of a flow regulator instead of a flow restrictor has several advantages, including the possibility to reduce significantly the reservoir pressure and to generate directly the pressure during the pump filling by using an elastic drug reservoir.

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.

This disclosure describes systems and methods for piloting a pneumatic valve using one or more piezoelectric blowers. According to embodiments, the one or more piezoelectric blowers may be coupled to the pneumatic valve to form a small, light-weight pneumatic valve that may be placed proximal to a ventilated patient, e.g., at the patient wye or the patient interface. Due to the close coupling of the one or more piezoelectric blowers, the pneumatic valve has a substantially shorter response time than traditional pneumatically piloted valves. Moreover, when piezoelectric blowers are coupled to the pneumatic valve in parallel, response time may be further decreased. Additionally or alternatively, when piezoelectric blowers are coupled to the pneumatic valve in series, pilot pressure may be increased as a function of the number of piezoelectric blowers in the series.

MicroElectroMechanical System (MEMS) devices can be fabricated completely of hydrogel materials. Such hydrogels can include polyethylene glycol with diacrylate functional groups (e.g., PEGDA), which are photopolymerizable in the presence of crosslinkers and photoinitiators. By using PEGDA monomers of different molecular weights and at different percentages, the mechanical properties of the polymerized gels and their respective permeabilities can be tuned. This spatial variation in properties and permeabilities can lead to different functionalities between different portions of the hydrogel MEMS device. Portions of the hydrogel device may be remotely actuated by applying wave energy, for example, a magnetic field, high intensity focused ultrasound, and/or infrared radiation. The remote actuation can allow the device to be actuated in vivo, for example, to allow the device to deliver a drug or other substance at a desired time and/or desired location within a patient.
