Embodiments of negative pressure wound therapy systems and methods for operating the systems are disclosed. In some embodiments, a system includes a pump assembly, canister, and a wound dressing configured to be positioned over a wound. The pump assembly, canister, and wound dressing can be fluidically connected to facilitate delivery of negative pressure to the wound. The system can be configured to deliver negative pressure based at least on a sensed pressured in a fluid flow path connecting a pump of the pump assembly and the wound dressing. The sensed pressure can be sampled, in some embodiments, synchronous with operation of the pump and can be used for controlling the pump. Increased efficiency, diminished noise and vibration caused by operation of the pump, reduced in energy usage, and better comfort for the patient can be attained.

Pressure sampling and supply of negative pressure in negative pressure wound therapy

A leak detection system including a sensor having a first state having a first condition when dry and a second condition when wet, and a second state adapted to monitor the operability of the sensor; a communication device operatively connected to the sensor; and an attachment element adapted to attach the leak detection system to a fluid component for monitoring fluid leakage.

Leak detection system and method of making and using the same

Multi-medicament infusion systems prevent cross-channeling of medicaments. A system may include one or more of an infusion pump, medicament reservoirs, a multi-channel fluid conduit, and an infusion set. Medicament reservoirs and/or collars may be sized and shaped differently such that the medicament reservoirs can only be inserted into the system under selected configurations.

Infusion system and components thereof

A method of monitoring at least one leak detection sensor, the method including the steps of: determining via a communication hub a first state of a sensor comprising a first condition when the sensor is dry and a second condition when the sensor is wet; determining via the communication hub a second state representing an operability of the sensor; communicating via the communication hub each of the states of the sensor to a Graphical User Interface (GUI); and displaying, via the GUI, a representation of the first and second states of the sensor.

Certain embodiments provide multi-medicament infusion systems for preventing the cross-channeling of medicaments. The system may include one or more of an infusion pump, medicament reservoirs, a multi-channel fluid conduit, and an infusion set. The medicament reservoirs and/or collars may be sized and shaped differently such that the medicament reservoirs can only be inserted into the system under selected configurations.

Synchronous pressure sampling and supply of negative pressure in negative pressure wound therapy

A conveyorized oven that provides uniform cooking with control of the heater and/or the conveyor belt speed. The oven includes a controller that monitors power consumption of the heater and uses the power consumption to control the heater and/or the speed of the motor that drives the conveyor belt. The power consumption is monitored by counting the on time cycles of a switch that connects and disconnects the heater to a power main. Changes in the power consumption due to changes in loading are used by the controller to reduce recovery times of the oven temperature to a set temperature by controlling the heater and/or the motor. By using a stepper motor, there is no need for a gear box.

Conveyorized oven and method for uniform cooking

The present invention provides methods and devices for maintaining the integrity of blood products throughout preparation, processing and application to a patient or desired site. Coding methods are incorporated onto or into processing and delivery containers which coding methods contain information identifying the donor and/or recipient. Additionally or alternatively the coding methods may contain information pertaining to a specific preparation or application process to be carried out. Blood product processors and blood product applicators include decoding methods to ensure the blood product is administered to the appropriate recipient and further that it has been prepared and applied according to desired processes.

Blood product delivery system

A blood processor is provided with a computer and memory, and external to the blood processor there is provided a general purpose computer system programmed with a convenient interface for creating scripts; the general purpose computer system translates the scripts into custom interpretive code adapted for processing by the computer in the blood processor, and the code is written into the memory of the blood processor via the computer in the blood processor.

System for control of blood processor

A low overhead controller for microstepping a stepper motor and a low overhead method for microstepping a stepper motor. The reduction in overhead in system processor is accomplished by the control circuit which dynamically interpolates motor positions between steps commanded from the processor. Also, the reduction in overhead is accomplished by a microstepping method used to effect microstepping resolution control by employing a stored look-up table which gives a resolution value at a given speed according to a predetermined function.

Stepper motor controller for microstepping a stepper motor and a method

A leak sensor system for use in liquid processing equipment is disclosed. Liquid is detected by a sensing resistor whose impedance decreases dramatically in the presence of liquid. The effect of this impedance drop on the output voltage of he sensor indicates a wet or moist state which may indicate leakage from the liquid processing. A terminal resistor is in the circuit beyond the sensing resistor ro provide a warning indicator when the sensing resistor is damage or disconnected. The leak sensor system is particularly useful in centrifuge equipment, e.g., for the processing of blood.

Leak detection system for liquid processing device

An apparatus for centrifuging and furthermore automatically handling a container (10) for separating a component, such as fibrin monomer, from plasma, where the container (10) comprises a cylindrical member (11) with a lower rim as well as a piston member (12) with a tubular piston rod (12) projecting upwardly from the upper end of the cylindrical member (11). The apparatus comprises a supporting turntable (1) with a first gripping member (27) releasably gripping the lower rim of the cylindrical member (11) when the container is placed thereon, the supporting turntable being connected to a first activator (5) for rotating the turntable (1) with the container (10) about the central axis thereof. Furthermore, the apparatus comprises a rotatably journalled piston activating mechanism adapted to activate the piston (12) by way of a second activator (21) and provided with a second gripping member (13) for releasably gripping the piston rod (12). The first gripping member (27) is adapted to automatically enter a locking engagement with the inner side of the cylindrical member (11) independent of the rotating position of the container (10) relative to the supporting turntable (1) and upon activation of a third activator (8) when the container (10) is placed on the supporting turntable (1). The second gripping member (13) is adapted to succeedingly and automatically enter a locking engagement with the piston rod (12) upon activation of a fourth activator (15).
