Dual pump arthroscopic irrigation/aspiration system with outflow control

A fluid pump system having a first fluid pump for pumping fluid from a source to a surgical site and a second fluid pump for removing fluid from the surgical site at a first predetermined rate, wherein said fluid pump system intermittently operates in conjunction with a surgical tool which, when operational, removes fluid from the surgical site at a second predetermined rate greater than said first predetermined rate, the improvement including a sensor for sensing a predetermined parameter of the surgical tool and providing an output signal indicating that the surgical tool is operating; and an actuating means responsive to said output signal to actuate said second fluid pump to remove fluid from the surgical site at second predetermined rate.

Stool Management System

A stool management system having a tubular body including a first end section disposable in a rectum of a patient and a second end section including a first connector which detachably mates with a second connector coupled to a collection container which receives waste matter passed through the tubular body from the bowel of the patient.

Devices and methods for cleaning contaminated body cavities

Provided is a method of cleaning a body cavity using a device by coupling a distal end portion of a first cannula to the housing such that a lumen is in fluid communication with the first portion of the inner volume, the first cannula coupled to a vacuum source, then coupling a distal end portion of a second cannula to the housing such that a lumen is in fluid communication with the second portion of the inner volume, the second cannula being coupled to a fluid source, inserting a portion of the housing into a body cavity, conveying a fluid from the fluid source to the body cavity via the lumen of the second cannula, and withdrawing the fluid from the body cavity into the vacuum source concurrently with the conveying the fluid, via the lumen of at least the first cannula.

Adjustable bowel treatment arm

An adjustable bowel treatment arm (110) features a telescoping shaft (112) having a proximal end and a distal end. A handle (118) is secured to the distal end of the telescoping shaft, while a pivot junction (122) positioned at the proximal end of the telescoping shaft. A stem has a proximal end and a distal end, where the distal end of the stem is attached to the pivot junction. A head (124) is attached to the proximal end of the stem.

Disposable pump chamber for an infusion pump

An apparatus, including a pump body having an internal shaft, and a piston disposed within the shaft and having a piston head that includes a first ferromagnetic element. The apparatus also includes a motor coupled to drive a reciprocal longitudinal motion of the piston within the shaft, and a pump chamber configured to be removably attached to the pump body and having a rigid wall defining a fluid inlet, a fluid outlet, and an aperture. The apparatus additionally includes a flexible diaphragm fixed across the aperture and having a second ferromagnetic element, which engages the first ferromagnetic element when the pump chamber is attached to the pump body so that the reciprocal longitudinal motion of the piston causes alternating stretching and contraction of the flexible diaphragm, thereby modifying a volume of the pump chamber.

Real-time intraoperative blood loss monitoring

Fluid introduction into the patient during surgery can be tracked more accurately. For example, saline is often introduced to a patient to clean an operating site. The saline is taken from a sterile bucket and introduced to the patient. In one described approach, the system senses the volume or weight of fluid in the sterile bucket and determines any decrease in the volume or weight to be an introduction of fluid to the patient. If, however, additional saline is added to the bucket, that addition is not counted in the fluid tracking and the further decrements from that new fluid amount is what is used to track fluid addition to the patient.

A vacuum assisted suction and irrigation system includes a suction and irrigation wand, an irrigation fluid supply, a vacuum source, and a fluid pump. The vacuum source is connected to a suction valve of the suction and irrigation wand to provide suction within the suction and irrigation wand. The irrigation fluid supply is connected to the suction and irrigation wand via the fluid pump to supply pressurized irrigation fluid to the suction and irrigation wand. The vacuum source is connected to the fluid pump to pressurize the irrigation fluid being delivered to the suction and irrigation wand.
