摘要： A catheter and a method of manufacture of a catheter which includes a relatively rigid body and a relatively soft tip for decreasing the likelihood of injury or damage to tissue such as the wall of a blood vessel or the heart when the catheter is used as a part of an invasive medical procedure such as angiography or angioplasty. The method includes the use of a core material which is sufficiently resistant to high temperatures to allow extrusion of catheter material thereover in the process of forming the catheter. The core controls the catheter's inside diameter, and is sufficiently heat resistant to allow its use through all subsequent manufacturing process steps involving the formation of the soft tip. The method of the present invention prevents foreign material build up within the inner diameter of the catheter during processing, eliminates the need for special fusion support mandrels during fusion of the soft tip onto the catheter, and maintains the integrity of the internal diameter of the catheter and soft tip during the thermal and pressure processes of the manufacture. The invention also includes a novel method of sizing and fusing the soft tip onto the catheter including the use of a piston member about the core which can apply pressure to the material forming the soft tip at any time before, during or after the thermal heating step.

摘要： A collection container for body fluids includes a bag having walls (66,68) adapted to move with relatively stiff and flexible sheet members(76,78). A squeezing force applied to the side edges of the members (76,78) causes them to bend outwardly thereby expanding the bag. The members have inwardly extending slots (106-112) which allow the bag to adopt a generally conical shape at top and bottom in the expanded condition. The specification also discloses a filter (120) between the bag inlet (22) and outlet (30) which filters incoming liquid but allows gas to pass directly from inlet to outlet without flowing through the filter.

摘要： An improved non-whip angiographic catheter Fig 6 has a preselected number of openings (42,44,46,48,52) of preselected size, location and orientation along the straight portion 20 of the catheter near the distal tip 40 so as to distribute the force of the high-pressure dye injection jets while maintaining the non-whip characteristics. At least one opening 42 in the catheter long portion 20 is provided facing the open end 38 of the tip portion so that the dye trajectories from the catheter tip opening 38 and the catheter long portion opening 42 are generally coplanar and perpendicular so as to interfere with each other for improved dye dispersion. At least two reaction openings 46,48 of predetermined size are provided on the opposite side of the catheter long portion 20 at preselected locations, the dye trajectories of these three reaction openings also being generally coplanar with the trajectories of the first opening and the open end of the catheter tip. The special openings have sufficiently small diameters and are specially staggered so as to reduce the possibility of kinking the catheter during placement of the catheter into position for diagnostic angiography.

摘要： An enteral nutrition pump system (10) operates in a cyclical manner with a period between cycles being selected in accordance with the desired fluid delivery rate. Each pump cycle may correspond to a single rotation of the rotor (18) or a fractional rotation of the rotor. Rotor rotation is sensed by monitoring of the AC component of current supplied to a DC motor driving the rotor.

摘要： A medical fluid delivery set is provided with a magnetic field source (30) in the region of its mounting (24) to a fluid flow control apparatus (10). The flow control apparatus (10) includes a magnetic field sensitive switching component (32) which detects the proper placement of the delivery set (18, 19, 16) on the flow control apparatus (10) and prevents operation of the fluid delivery system unless a set is in proper position.
