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.

Described herein are devices and methods for irrigating and suctioning fluids from the lumens or cavities of a mammalian body. The devices include a malleable irrigation tube and a suction tube that is slidably mounted upon the irrigation tube.

Systems, methods, and apparatuses for irrigating a tissue site are described. The system can include a tissue interface and a sealing member configured to be placed over the tissue site to form a sealed space, and a negative-pressure source fluidly coupled to the sealed space. The system includes an irrigation valve having a housing, a piston disposed in the housing, a fluid inlet to fluidly couple a fluid inlet chamber to a fluid source, and a fluid outlet to fluidly couple a fluid outlet chamber to the sealed space. A piston passage extends through the piston and fluidly couples the fluid inlet chamber and the fluid outlet chamber, and a biasing member is coupled to the piston to bias the irrigation valve to a closed position. The negative-pressure source is configured to move the piston between the closed position and an open position to draw fluid to the sealed space.

A novel irrigation and aspiration system is disclosed. A pump (6) is disposed on an irrigation tube (2) for delivering irrigation fluid. The irrigation tube (2) is connected in series with a check valve (3) and then connected with a first port of a tee joint (4); a second port of the tee joint (4) is connected with a suction tube of a negative pressure device through an aspiration tube (5); an electronic choke device (7) is installed on the aspiration tube (5); a third port of the tee joint is connected with an irrigation and aspiration common tube (8) also connected with a terminal execution device. The electronic choke device (7) and the pump (6) are controlled by a host computer. The electronic choke device (7) is turned off when the pump (6) works; and the pump (6) is stopped when the electronic choke device (7) is turned on.

A self-contained ocular surgery instrument, including a power module having a body presenting a mating coupler and including a compressed gas supply; a fluid reservoir; an aspiration pump; an aspirated material reservoir and a control panel. The mating coupler is structured to receive and couple to at least one module that facilitates performance of an eye surgery task. The compressed gas supply is coupled to the aspiration pump and the aspirated material reservoir is in fluid communication with the aspiration pump to receive aspirated material from the mating coupler. The fluid reservoir is in fluid communication with the mating coupler such that fluid is supplied under pressure to the mating coupler and thus to the at least one module that facilitates performance of an eye surgery task. The control panel is in controlling communication with the compressed gas supply, the aspiration pump and the aspirated material reservoir.

A method and apparatus that reduces the time and trauma associated with tissue removal procedures such as Ultrasound Assisted Liposuction, which emulsifies and then extracts unwanted adipose from a patient's target zone. Emulsification and suction are optimized and performed in a synchronous manner by a single apparatus to improve the outcome and minimize, if not eliminate, the limitations, risks and complications caused by current state of the art techniques.

Pressure control unit for an ophthalmic irrigation/aspiration system having a chamber with an upper part for storing air and a lower part for storing a surgical fluid to be irrigated or aspirated, the pressure control unit including a negative pressure source, a positive pressure source and an adjustable valve arrangement. The adjustable valve arrangement includes a vacuum port connected to the negative pressure source and a pressure port connected to the positive pressure source. The adjustable valve arrangement also includes a main port in controllable fluid communication with the vacuum port and the pressure port and the main port is connected to an upper part of the chamber.

Methods and systems for administering directed fluidics during a medical procedure for removing an object are disclosed. A method includes inserting first and second medical instruments into a treatment site, providing irrigation and aspiration of the treatment site through the first and second medical instruments, determining a characteristic of one of the irrigation and the aspiration, and selecting a characteristic of the other of the irrigation and aspiration based on the determined characteristic.

A system for feeding and aspirating a patient's stomach may include a feeding bag, a collection bag, and a water source interconnected with each other via a double action piston pump and further connected to a nasogastric tube via the double action piston pump. An exemplary double action piston pump may be utilized for pumping contents of the feeding bag into the patient's stomach, pumping out contents of the patient' s stomach into the collection bag, injecting water from the water source into the patient's stomach.

A manual clot aspiration and filtration system enables a method of removing a clot without general anesthesia and the expense of an operating room. An aspiration and filtration system for bodily fluid utilizes a syringe coupled with a filter unit to draw bodily fluid through the filter unit to collect debris on the filter. A flow valve may then be turned and the plunger depressed to force the filtered fluid back into the body. The filter may be configured to capture particles such as blood clots and plaque. The filter unit has a cover that can be removed for inspection and/or removal of the collected debris. When the cover is replaced, trapped air may be removed by turning the flow-valve to a purge direction and pressing the plunger into the syringe to force fluid back toward the filter unit to purge the trapped air through the purge valve.
