  • Patent number: 7560653
    Abstract: An improved electrical switch nut and boot seal assembly is provided having a stainless steel or aluminum nut and flexible boot to provide an exemplary fluid seal between an electrical switch and the electrical switch nut and boot seal device. The electrical switch may be a toggle switch or push button type circuit breaker or any other type electrical switch device where the advantages of the present invention make themselves useful such as may exist on any control panel of a recreational vehicle (i.e., boat, snowmobile, or other type land or water craft). A key feature of the invention is that the nut and flexible boot are separate pieces that can be mixed and matched to change the outer shape and/or colors of the various nuts and/or flexible boots. The fluid and moisture seal is provided by capturing a flange of the flexible boot between various inner surfaces of the nut and electrical switch.

  • Patent number: 5830401
    Abstract: A catheter is disclosed which includes a mechanical connection between the strain relief thereof and the hub. The strain relief operates both to secure the catheter tube to the hub and to provide strain relief for the catheter tube. The strain relief connection is assisted in gripping the catheter tube by intentional overstressing of the catheter hub during manufacture thereof to expand the hub wall and generate residual hoop stresses therein which assist in securing the catheter tube within the hub.

  • Patent number: 5702342
    Abstract: A mounting apparatus for mounting a mounting post in a preselected position. The apparatus includes a primary casing having a side wall and an end wall which define an interior space within the primary casing. A mounting post having a frictional retention member disposed thereon is mounted through the primary casing such that the frictional retention member is disposed within the interior space defined within the primary casing. The mounting apparatus further includes a second end wall constructed to be secured to the primary casing. Securement of the second end wall to the primary casing causes the frictional retention member to be frictionally retained between the first end wall and the second end wall.

  • Patent number: 5665064
    Abstract: A gastroenteric feeding tube is provided which is ideally adapted for endoscopic placement through an endoscope having a working channel and a steerable tip. The feeding tube is provided with a longitudinal length sufficient to allow the endoscope to be removed from about the feeding tube without disturbing the distal placement of the feeding tube within the patient's intestines. After the feeding tube has been properly positioned within the patient and the endoscope has been removed from about the feeding tube, a connector is securely attached to the proximal end of the feeding tube to allow it to be connected to a feeding pump, or the like, to provide nourishment to the patient.

  • Patent number: 5601541
    Abstract: A footstand for stabilizing or securing a body of a medical device against overturn. The body may especially be a chest drainage unit designed and configured to receive and collect fluids from a medical patient. The invention comprises a two leg component rotatable footstand which incorporates a gear driving mechanism which operates between the legs to simplify the action of pulling out the respective legs of the footstand. The gear driving mechanism allows the medical technician to activate the footstand by simply pulling out either the front or back leg to its stabilizing position, the other leg will automatically be rotated into its stabilizing position. A detent is provided which will provide a secure "click" sound so that a medical technician will know the legs have been pulled out away from the CDU a sufficient distance to provide the proper stabilization for the CDU.

  • Patent number: 5554127
    Abstract: A syringe needle thimble cap and its method of use is shown such that the thimble cap has a porous plastic, hydrophilic core captured within a cylindrical cap member for use with an arterial blood gas syringe barrel and needle assembly. The syringe needle thimble cap has a generally thimble-shaped cap with a proximal opening. The porous plastic core material is positioned within the thimble cap distally to the proximal opening, and the core material is held in place by an inwardly extending ring to prevent its removal. An open or hollow space is created distally to the porous material which is otherwise bounded by the interior surfaces of the thimble cap.

  • Patent number: 5549139
    Abstract: A pneumatic control system for providing pressurized air and vacuum to ophthalmic microsurgical instruments. The pneumatic system is constructed in a drawer assembly to allow it to be readily inserted into or removed from a modularly construct ed cabinet of a microsurgical control console.In addition, the pneumatic system improves upon existing pneumatic control systems by providing a third mode of microscissors operation from a single pneumatic port. The third mode is made possible by a high speed three-way solenoid control valve which provides rapid pulses of air to the pneumatic port.

  • Patent number: 5545174
    Abstract: A lancet type device having a movable and retractable lancet tip is disclosed. The lancet tip extends beyond the end of a lancet body. The device includes an actuating mechanism that moves and retracts the sharp distal lancet tip linearly into and out of contact with a patient's skin. The actuating mechanism includes an arm with a substantially "V" shaped groove. In one embodiment, the arm extends away from and pivots around the proximal end of the device. In another embodiment, the arm moves transversely across the device. A cylindrical cam follower protrudes from the lancet body. Contact between the groove and the cam follower moves the cam follower, and consequently the lancet body, in a linear direction along the axis of the lancet body.

  • Patent number: 5527007
    Abstract: A CDU hanger mount assembly and hanger is provided. The mount assembly and hanger allows the CDU to be supported by an object for supporting the CDU while the connecting point between the hanger mount and the pivot end of the hanger may be selectively moved from a point midway between the front and back of the CDU top toward the back of the CDU. This allows the CDU to be less displaced from the vertical upon displacing contact with an object such as a bedframe piece. The hanger and hanger mount assembly allows the alignment of the indicia on the CDU with the top surface of the material collected in the CDU to be a more accurate representation of the actual volume of material collected in the CDU. The mount assembly and hanger may also be used with medical devices other than CDUs.

  • Patent number: 5437675
    Abstract: A bone punch for altering the cross-section of a tunnel formed in a bone, the punch having a punch body with a distal region, a proximal region, and a plurality of planar guide faces extending between the distal and proximal regions to define a polygon in cross-section. The distal region terminates in a narrowed leading end to facilitate entry into the pre-drilled tunnel. A shaft is connected to the proximal region to transmit a force to drive the punch body into the bone tunnel to alter the cross-section shape of the bone tunnel to match the polygonal cross-section of the punch body.

  • Patent number: 5397334
    Abstract: An assembly for preventing movement of a sharp lancet tip out of a lancet device of the type having a linearly movable and retractable lancet tip is disclosed. The lancet device has a patient contacting or distal end and an opposed proximal end. The lancet device has a lancet that is substantially encased in an elongated molded plastic lancet body. The lancet has a sharp tip that extends beyond the end of the lancet and is enclosed in a removable cap. The distal end of the lancet has a pair of retainer arms that extend away from the lancet body on opposite sides of the lancet body parallel to the axis of the lancet body. The distal end of the retainer arms extend slightly beyond the distal end of the lancet body and are curved toward the axis of the lancet body to contact the outer surface of the cap. Each retainer arm has a stop, located near the distal end of the retainer arms. The distal end of the lancet body fits in a chamber in the lancet device.
