The present invention is directed to a wound drain catheter for draining fluid from, or supplying medication to, a wound in a patient. The wound drain catheter comprises a drain, a flexible outflow tube, and means for connecting the drain to the flexible outflow tube. The drain comprises a hollow core having a longitudinal axis; plural struts extending outwardly from the hollow core and being closed to the hollow core; and plural overhangs connected to the outward ends of the struts, respectively, the overhangs cooperating with the struts to form plural longitudinal lumens, the overhangs cooperating with each other to form, on the outer surface of the drain, segments of a segmented, closed curve with gaps between the segments providing plural longitudinal grooves for fluid communication between the wound and a respective lumen, the grooves sized to inhibit tissue from growing therein and debris from passing therethrough. The present invention also includes a method for draining fluid from, or supplying medication to, a wound in a patient.

Described herein are devices, systems, kits and methods for measuring intra-abdominal pressure (IAP) from a patient catheterized with a urinary catheter system. Devices may include a bypass lumen configured to connect to a pressure transducer, a sampling port connector connected to the bypass lumen, a drain tube housing configured to at least partially enclose a portion of the drain tube of a urinary catheter system, and a clamp mechanism. The sampling port connector may be configured for removable attachment to the sampling port of the urinary catheter system to form a fluid connection between the urinary catheter system and the bypass lumen of the IAP device. The clamp mechanism may be configured to controllably occlude the lumen of the urinary catheter system drain tube.

An improved water closet flange for connection to a plumbing fixture is described. The improved flange comprises an anchoring element or outer flange, connected to a flexible conduit tube or flexible sleeve, in which is attached an O-ring type of gasket. The improved flange connects a toilet bowl outlet to a waste drainpipe outlet without any flow reduction in between both connecting elements. The improved flange allows the connection between a toilet bowl discharge and a well placed vertical waste drainpipe. The improved flange also allows the connection between a toilet bowl discharge and a waste drainpipe outlet that is offset, horizontally oriented, or diagonally placed. The improved flange may further comprise an O-ring type of gasket disposed on the exterior of the flexible sleeve to provide a tight seal between the outer surface of the flexible sleeve and the inner surface of a waste drainpipe. The flexible sleeve can be implemented in a variety of sizes or diameters, including, for example, 3 inch (7.5 cm) and 4 inch (10 cm) diameters. An alternative embodiment of the flexible sleeve can fit either 3 inch or 4 inch drainpipes with the help of an appropriate O-ring seal of the appropriate dimensions.

A toilet leak containment assembly for preventing water leaks from a toilet during flushing onto the support flooring into which the toilet is attached. The leak containment assembly contains a leak collector for installation between the toilet base and the support flooring for preventing the water leaks onto the support flooring during flushing. The leak collector contains an attachment flange for attaching the leak collector to the support flooring, a collector pan for collecting water leaks during flushing, and an outlet pipe in fluid communication with the collector pan for channeling the leaks into the plumbing drain pipe. It also contains a leak seal assembly for installation and sealing between the toilet base and the leak collector. The leak seal assembly contains a flow channel for channeling water flow into the outlet pipe of the leak collector, and a seal for sealing between the toilet base and the leak collector.

The invention discloses an efficient aeration tank which comprises a tank wall, a bracket, a motor, a transmission shaft, an aeration plate, a blower, a water inlet pipe and a drain pipe, wherein the bracket is fixedly connected with the upside of the tank wall; the lower surface of the bracket is fixedly connected with the motor; a shaft extension end of the motor is fixedly connected with the transmission shaft; a right rotating shaft is rotationally connected with an inner wall on the right side of the tank wall; a left rotating shaft is rotationally connected with an inner wall on the left side of the tank wall; stirring plates are fixed on the left rotating shaft and the right rotating shaft; the tail end of the transmission shaft is fixedly connected with the upper surface of the aeration plate; sewage in a middle layer is turned over vertically by the stirring plates; the sewage and air are mixed more uniformly; the aeration plate exhausts the air into the sewage in a rotating process for aeration of the sewage; the aeration plate exhausts the air while rotating; the air and the sewage are mixed more intensively; the stirring rod scatters bubbles exhausted by the aeration plate; the contact area between the air and the sewage is increased; and an aeration effect is further improved.

A self-cleaning urinal anti-splash device having a series of angled deflectors which send the urine stream ever deeper into a series of channels leading down toward the urinal drain. The angled deflectors not only send the urine stream ever deeper into the channels, but they simultaneously prevent the urine from exiting the channels in any direction other than downward toward the drain. This is accomplished by virtue of the fact that inner faces of the deflectors are adapted to deflect the urine back toward the urinal wall. No plane perpendicular to the direction of the initial urine stream is presented to the user. Gravity then causes it to flow to the drain. The device is also self cleaning because there is nothing to prevent the water of a flush cycle from passing through the vertical channels by gravity feed, thereby removing all the urine on the deflector surfaces. The device can be made of metal, plastic, rubber, or other inexpensive easily moldable substance. It has notches in the channels so the device is easily trimmed to size.

A closet flange is provided for coupling the base of a toilet to a drain pipe. A main generally cylindrical body portion is dimensioned for connection to the upper end of a drain pipe and has a through bore for communicating with the interior of the drain pipe. An attachment flange portion extends radially outward from an upper end of the cylindrical body portion and is configured for connecting to the base of a toilet. A knockout temporarily seals the through bore and is removable by breaking away a peripheral edge of the knockout. A retainer extends radially inward from an inner wall of the cylindrical portion below the knockout and is configured to prevent the knockout from falling down the through bore and into the drain pipe when broken away in order to prevent drain clogging.

Most commercial & residential buildings have rainwater collection systems that consist of leaders and gutters that collect water coming off the roof. These leaders and gutters are connected to drain pipes that channel the water away from the structure, usually into a dry well or storm drain. A substantial add-on to the leader and gutter system is a debris trap with an overflow port. The debris trap / overflow port may be attached to the leader at waist height (for easy access) to collect leaves, tree droppings, windblown litter and other materials. This debris can be easily discarded by opening an access panel to empty a built-in strainer. When a dry well or storm drain becomes saturated, water will back up through the leader causing seepage and overflow into the building and create erosion that can damage the foundation. The function of the overflow port is to divert water from the drain pipe away from the foundation. The debris trap / overflow port system not only channels water away from the building but also prevents overflow of organic materials that can accumulate along the foundation.
