Abstract: The present invention is an improved ostomy fluid tube and method for its use comprising a collapsible retention bolster for securing the tube to the inner stomach wall and fascia. The retention means comprise several resilient leaf or petal-shaped flanges circumferentially arranged about the feeding tube at a distal point thereon. The otherwise flat, circumferentially arranged flanges possess notches or grooves which facilitate collapse or folding of the retention means for easier removal through an ostomy or other internal cavity.

Abstract: An apparatus for containing a liquid biological sample and for performing a biological process thereon comprises a sample area for receiving the sample, at least one reaction area in fluid communication with the sample area, a pneumatic area in pneumatic communication with the reaction area and the sample area, and a pneumatic port in the pneumatic area for connection of the apparatus to a pneumatic aspiration/dispensing pipette. The pneumatic aspiration/dispensing pipette provides for controlled flow of the liquid biological sample between the sample area and the reaction area. To reduce evaporative loss of the sample from the apparatus, a sample tower is provided in fluid communication with the sample area. A similar tower may be provided at the pneumatic port to reduce evaporative loss through the pneumatic area.

Abstract: A sprayer includes a tank having a pump for pressurizing the liquid contents of the pump. The sprayer has a hose extending from the tank for receiving liquid directly from the pump, a spray control valve and discharge nozzle for directing the spray. One or more parts from the pump inlet to the discharge nozzle are adapted to fail after a certain period of time with reuse of the sprayer.

Abstract: A sprayer includes a tank for liquid, a pump for pressurizing the liquid, a hose for the liquid under pressure and a manually activated spray control valve coupled with the hose and upon digitally sliding a valve body a valve plug is adapted to engage a valve seat to close the valve and disengage the valve seat to open the valve.

Abstract: A gastrostomy feeding tube removal device is comprised of a hollow cylindrical body, a conical head formed at one end and preferably a cap or top at the other to assist in grasping the tool during use. A sheath covers the remaining body portion and is slideably moveable thereon. In use, the gastrostomy tube is pulled through the device which enters the stomach through an ostomy of the patient. Upon contacting the retention bolster means proximate the inner stomach lining, the plastic sheath is pressed forward against the extended members of the retention means thereby collapsing them and withdrawing them into the sheath. The device is then withdrawn from the patient's body simultaneously removing the tube as well.

Abstract: A one time use non reusable sprayer includes a tank having a pump for pressurizing the liquid contents. A connection of the pump to the tank, if severed will result in destruction of the tank and pump to prevent reuse of the sprayer. The sprayer has a hose extending from the tank, a spray control valve and discharge nozzle for directing the spray.

Abstract: Improvements and accessories for a septum closed T-shaped blood access device adapted for implantation into a patient. The implantable device has a stem portion extending above the skin of the patient and defining a septum closed opening into the device. The improvements include an improved septum having a groove in the side thereof encircling the septum and an elastomeric ring carried within the side groove, an improved needle assembly which provides access to the circulatory system through the septum, and a flexible cap for sealing the stem of the implantable device from the outside atmosphere which may be fitted in place or removed without the necessity of specialized tools.
