A low-cost and simple-to-use system and method to facilitate a prophylactic pleural lavage protocol at the time of thoracostomy tube placement for traumatic hemothorax in order to reduce the need for secondary intervention for the management of retained hemothorax. The invention may be used in conjunction with existing chest tubes and be administered at the time of initial chest tube placement, and continued at the bedside (by a bedside nurse) over the duration of chest drainage, as necessary. The system includes an operator device that semi-automatically administers a pleural lavage protocol consisting of saline instillation, and suction to slow the clotting process, prevent “gelling” of blood, and maintain drainability.

The invention discloses a percutaneous puncture and dilation visible irrigation-suction system and a method of using the same. The system comprises a main tube, which is contiguous with the sheath tube and has an end for an endoscope insertion. The sheath tube comprises an inner sheath and an outer sheath joined together in a sleeve type. There is a space between inner and outer sheath. The inner sheath is connected to main tube, together building a channel via which the endoscope is inserted and withdrawn. The sheath tube is connected to main tube after completing puncture and dilation, then endoscope system is introduced for observation and operation. The present invention provides a percutaneous puncture and dilation visible irrigation-suction system and a method of using the same, with a continuous controllable visible negative pressure aspirator, achieving high irrigation and powerful suction efficiency, as well as clear endoscopic view.

New and useful systems, apparatuses, and methods for providing negative-pressure therapy with instillation of topical treatment solutions are described. An apparatus may comprise an exudate container, a solution source, and a pneumatically-actuated instillation regulator. The instillation regulator may be coupled to the exudate container and to the solution source, and negative pressure from a negative-pressure source can actuate the instillation regulator. In some embodiments, a negative-pressure source may be configured for a negative-pressure interval and a venting interval, and the instillation regulator can be configured to draw instillation solution from the solution source during a negative-pressure interval and to instill the solution to a dressing during a venting interval.

This invention proposes the construction of a simple closed loop system for continuous flow harvesting, collection, syphoning, and grafting of large volumes of fat. (See FIG. 1—a schematic of the overall setup). This invention uniquely bypasses the standard cumbersome and time-consuming process, that mainly being the need to first transfer fat into individual syringes prior to grafting into the patient. This is traditionally done with unmeasured, manual pressures as generated by a simple plunger syringe. It can be messy and sloppy, with loss of fat. In contrast, this innovative concept presented here simplifies the whole process into a closed loop, from the donor harvest site, and then back to the patient. The concept is modular, drawing on commonly used, interchangeable parts and pumps present and available in most basic community hospital operating rooms. The major benefit is a significant reduction in time to transfer. However there is also a simplification of the process with less air exposure time, consistent controlled limit on flow pressures, and a simple on off control that can be held in one hand. The system is adaptable to standard liposuction and introduction cannulas through standard liposuction tubing and a luer lock connection. Collection canisters are also interchangeable.

Systems, devices and methods for use in liposuction and infusion medical procedures including handheld devices, micro-cannulas, curved cannulas vacuum pressure changing features.

A medical device is provided comprising a first port; a second port in fluid communication with the first port; and a third port in selective fluid communication with both the first port and the second port; a sealing membrane disposed between the third port and both the first port and the second port, the sealing membrane is configured to move between a first position preventing fluid communication between the third port and both the first port and the second port and a second position allowing fluid communication between the third port and the first port, wherein movement of a fluid supplied to the medical device at the third port moves the sealing membrane from the first position to the second position.

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.

Valve devices are provided for draining fluids from and/or infusing fluids into a patient's body that include a housing including first, second, and third connectors, a primary fluid path communicating between the first and second connectors, and a secondary fluid path communicating from the primary fluid path to the third connector. First and second valve members are movable within the housing between first positions wherein the valve members do not obstruct the primary fluid path and second positions wherein the primary fluid path is at least partially closed. The third connector may be configured to prevent fluid flow therethrough unless a mating connector is fully coupled thereto. The valve members may be selectively closed to isolate portions of the flow path to allow a source of vacuum or fluid coupled to the third connector to aspirate or infuse fluid along portions of the primary fluid path.

A surgical handpiece includes a housing gripped by a user, and an aspiration pipe that is attachably and detachably held by the housing and aspirates a liquid.

Fecal management methods and apparatuses (e.g., devices, systems, etc.) are described herein. The fecal management apparatuses may apply one or more fecal removal cycles of suction and irrigation (and in some examples air) to actively remove fecal material. The apparatus may control the timing of delivery of the fecal removal cycles as well as the parameters of the applied suction, irrigation and/or air within and between fecal removal cycles.
