A flexible body fluid drain tube has substantially flat cross section with a pair of parallel longitudinal internal ribs along one substantially flat wall which are spaced apart a distance greater than their respective distances from the adjacent edges of the flat wall, a central internal longitudinal rib along the opposite substantially flat wall, and a pattern of drain holes along both flat walls in line with the parallel ribs. The ribs prevent the tube from collapsing even when the tube is su...

A surgical drain for operative and post operative usage providing a core comprising a pliant drainage conduit having through wall passages throughout its lenth from its distal end to a point inset from its proximal end and a co-extensive pliant irrigation conduit open at its ends, a padding layer of soft, non-friable absorbent material surrounding said core from its distal end to a point opposite the proximal end passages of the drainage conduit, a soft rubber or like sheathing surrounding the p...

A flow control system for the positive control of drainage of fluid from a region of the body to be drained to a drainage site at another location. It provides means for the controlled positive shut-off of said drainage. The system includes a flow valve having an internal flow cavity with an inlet and an outlet. A partition divides the cavity into a pair of chambers, the inlet and outlet opening into different respective ones of the chambers. A port is formed in the partition, and a fluid actuat...

A physiological drainage system for draining liquids from a source of the human body to a region where it is disposed of. The latter region is at a different elevation from the source region. The system is provided with a control which is responsive to downstream suction. When the suction is excessive, the control closes the system to flow so as to prevent over-drainage of the source region. The control comprises a valve which remains open to flow at normal rates and downstream suction levels, a...

A waterplay structure is provided for home use which is easily assembled and which provides a variety of interactive water forming devices and adjustment valves for exciting backyard play. Play participants can assemble the play structure and then control the various water effects to cool and entertain the whole family.

A Vee machining center employing two distinct non-captive tool retaining means which are, each, operable to retain a tool in substantially the same position as a function of the tool releasing movement of the other. One of the retaining means consists of the usual flexible drive belt for rotating the tool while the other comprises a mechanical gripper providing temporary support for the tool during tool interchange. Two distinct, alternately usable power sources provide two distinct speed contro...

A body massage apparatus for propagating vibrations of a vibrator to a selected part of the human body through a pad member. The body massage apparatus generally includes a case in which a motor is mounted for producing vibrations. The attaching components, are secured to the case for attaching a selected pad member thereto, and they comprise a dial rotatably mounted in the case, and directly accessible to the user, for engagement with the pad member.

As an article of manufacture an improved drain tube which is flexible and pliable for use after surgical operations and which includes a plurality of ribs arranged in such a fashion about the interior of the column of the tube so that the tube cannot be collapsed and which at all times promotes drainage of body fluids as healing occurs.

An endoskeletal or exoskeletal participatory water play structure comprised of play elements, water carrying conduits with attached water forming devices, associated valves, and issuing water effects, all of which define a three dimensional structure whereupon participants can manipulate valves to cause controllable changes in water effects that issue from the various water forming devices, and thus, alter the embodiment's overall appearance, sound and feel resulting in participant and observer ...

A flexible surgical T tube with a continuous open slit extending across the top of the cross tube is disclosed. This improved T tube allows the tube to be removed from a duct after surgical implantation by simple non-surgical withdrawal while minimizing wound stress and trauma in the duct.
