A device for simulating catheterization in a body channel of a patient comprising, a catheter having an elongated shaft, an inflation balloon on the shaft, and an inflation lumen extending along the shaft and communicating with the balloon. The device has a sleeve of flexible material defining a cavity to receive the portion of the shaft containing the balloon, with the sleeve having a sufficiently small width such that the balloon contacts walls of the sleeve when inflated. The sleeve has a line of weakness which ruptures when the balloon is sufficiently inflated unless relieved of pressure prior to rupture of the sleeve.

Abstract:
A catheter assembly comprising, a catheter having an elongated shaft, and an elongated sleeve of flexible material covering at least a substantial portion of the catheter. The sleeve has a pair of opposed first and second walls extending between a pair of opposed longitudinal fold lines at sides of the sleeve with the catheter being received between the walls in a generally flat configuration of the sleeve. The sleeve has a circumferential cuff of enlarged dimensions defining an open distal end of the sleeve.
A vent for a liquid drainage system comprising, a conduit having a lumen for drainage of liquid, and a filter pervious to air and substantially impervious to the passage of bacteria, with the filter communicating with the atmosphere. The vent has a valve assembly communicating between the lumen and the filter, with the valve assembly being movable between a first closed position to prevent passage of liquid from the lumen against the filter, and a second open position to permit passage of air between the atmosphere and the lumen through the filter.
A device for collecting body fluids from a patient comprising, a container having a chamber to receive the body fluids. The device has a receptacle associated with the container and having a cavity to retain an antiseptic agent, with the receptacle cavity communicating with the container chamber through a relatively small opening, and a device for generating pressure in the receptacle cavity to cause passage of the agent from the receptacle cavity to the container chamber through the opening.
A liquid drainage system comprising, a urine meter comprising a first container having a compartment to receive the liquid, and a second container having a cavity alongside the first container, with the first container having an opening adjacent an upper portion of the first container communicating between the compartment and cavity to permit passage of liquid between the compartment and cavity. The system has a receptacle having a chamber supported below the urine meter, a first conduit communicating between the compartment and receptacle chamber, and a second conduit communicating between the cavity and the receptacle chamber. The system has a device for simultaneously opening and closing the first and second conduits to empty the contents of the compartment and cavity into the receptacle chamber.
Collection Device With Antiseptic Liquid For Body Fluids
A device for collecting body fluids from a patient comprising, a container having a chamber to receive the body fluids. The device has a receptacle permanently secured to a wall of the container and having a cavity to receive a liquid agent, with the receptacle cavity communicating with the container chamber through a relatively small opening adjacent a lower portion of the cavity. The receptacle has an aperture in an upper portion of the receptacle communicating between the cavity and the outside of the receptacle.

International Classification:
A61M 100
US Classification:
128760
Abstract:
A fluid sampling chamber assembly having a housing, a chamber within the housing for temporary storage of sample fluid and a pair of special sensor walls on opposite sides of the chamber for engagement by ultrasonic sensor probes. The sampling chamber is trough-shaped with an open top for both receipt and discharge of sample fluid. An inlet and outlet of the chamber housing are continuously open.

US Classification:
604323
Abstract:
A liquid drainage system comprising, a receptacle having a chamber to receive and collect the liquid. The system has a drip chamber having a vent with a bacteria filter covering the vent, and an annular wall having a lower edge defining a valve seat, with the seat being disposed at an acute angle relative to the horizontal when the receptacle is in an upright position. The system has an anti-reflux valve comprising a sheet of flexible material extending across the drip chamber such that the sheet is sufficiently large to engage against the seat peripherally around the drip chamber. The system has a device for retaining an upper portion of the valve against an upper portion of the seat, such that a lower portion of the valve flexes away from the seat when the receptacle is placed in an upright position, and the lower portion of the valve flexes against the seat when the receptacle is disposed in a horizontal position.
