摘要： An indwelling urethral catheter sizing system comprises sets of substantially equal length indwelling urethral catheters (14) having various balloon spacings (a, b, c), from bladder balloons (2) to urethral anchoring cuff balloons (36). A method of implanting an indwelling urethral catheter from the sets involves first determining a patient's interballoon urethral segment length, from his bladder to his bulbous urethra immediately downstream of what remains of his prostate gland. A urethral sizing catheter having a balloon spacing corresponding to the interballoon urethral segment length is inserted in the patient to determine the clinical length of the patient's urethral tract from his bladder to his penile meatus. A male indwelling urethral catheter is then chosen from the sets having a balloon spacing corresponding to the patient's interballoon urethral segment length and the clinical length determined with the urethral sizing catheter. The urethral sizing catheter can be used for filling and voiding the bladder.

摘要： An analytical specimen cup system (10) includes a lid (14) comprising outer and inner partitions (42, 40) for defining a test space (44) having a chemical test strip (30) mounted therein. The inner partition defines a raised test-strip shelf (61) on which the chemical test strip is mounted, a sump (64) with a floor (62) positioned substantially below the raised shelf, and an opening-defining member (48) for defining an opening (50) to allow test fluid to be transferred from an analytical specimen cup (12) to the test space. A mouth (60) of the opening is vertically positioned intermediate the raised test-strip shelf and the sump floor. In one embodiment the analytical specimen cup has a membrane (24) covering its mouth (18) and is sterilized separate from the lid. The inner partition includes a specimen-release device (52) for uncovering the opening of the opening-defining member as well as for piercing the membrane.

摘要： A pole clamp assembly (10), and a method of using same, involves two jaws (14, 16) mounted on a base frame, or housing, (12) with a first (14) of the jaws being movable on the frame along two parallel curved tracks between closed and open positions and a selectively-actuatable biasing mechanism (18) comprising an elastic or spring member (38, 102) attached between the movable jaw (14) and a reel or hub (36, 36'). By selectively moving the hub between open and closed positions, the biasing mechanism moves the jaw between the closed and open positions, but if the jaw is held in the closed position, for example, which it will be if the clamp is engaged with a pole, the biasing mechanism flexes when the hub is moved to the open position to allow the movable jaw to remain in the closed position. When the jaw is no longer held in the closed position it snaps to the open position under the influence of the biasing mechanism. Additionally, a spring loaded lock (100) which holds the movable jaw in the open position can be automatically actuated by placing a member to be clamped between the two jaws to automatically release the movable jaw, thereby allowing it to snap to the closed position under the influence of the biasing mechanism.
摘要翻译：杆夹组件（10）及其使用方法包括安装在基架或壳体（12）上的两个夹爪（14,16），其中第一（14）夹爪可在框架上移动两个平行弯曲的轨道在闭合位置和打开位置之间以及可选择性致动的偏压机构（18），其包括附接在活动夹爪（14）和卷轴或轮毂（36,36'）之间的弹性或弹簧构件（38,102）。通过选择性地将轮毂在打开位置和关闭位置之间移动，偏置机构使夹爪在关闭和打开位置之间移动，但是如果夹爪保持在关闭位置，例如，如果夹具与杆当轮毂移动到打开位置时，偏置机构弯曲以允许可动夹爪保持在关闭位置。当钳口不再保持在关闭位置时，它在偏置机构的影响下卡扣到打开位置。此外，通过将待夹紧的构件放置在两个夹爪之间来自动地将可动夹爪保持在打开位置的弹簧加载的锁（100）自动地启动，从而允许其卡扣到下面的关闭位置偏置机构的影响。

摘要： A multi-lumen-catheter flow valve system (10) comprises a catheter (14) having three separated lumens (70, 72, 74), each lumen having a separate outlet opening (122a-c) at a distal end portion of the catheter, and a selective-in/all-out valve apparatus (12). The valve apparatus has red, grey and blue input ports (46, 48, 50) and center, first offset and second offset output ports (64, 66, 68), each of the input ports being selectively coupled to a fluid source (16, 18 or 20) and each of the output ports being coupled to a lumen of the blood vessel catheter. The valve apparatus can be adjusted to selectively transmit fluid(s) entering the three input ports to the three output ports without mixing the fluids and to transmit fluids entering a lesser number of input ports than output ports to the three output ports, also without mixing the fluids.

摘要： An improved medical lavage apparatus (10) includes guide/lock/stop tabs (122) which are inserted through a medical lavage syringe housing (20) into irrigation and aspiration bores (30, 34) thereof for engaging longitudinal ribs (68a-d, 69a-d) of irrigation and aspiration plungers (24, 26) to prevent their rotation and a circumferential latch rib 134a of the aspiration plunger for locking the aspiration plunger in an inserted position. The tabs also contact end circumferential ribs 70' of the plungers for providing stops to prevent the plungers from being removed from their respective bores. The tabs comprise two legs (126) which straddle the longitudinal ribs, with a longitudinal rib 68a of the aspiration plunger having a notch (140) at the tab in the aspiration bore to allow rotation of the aspiration plunger when it is in the inserted position for engaging the legs with the circumferential latch rib.

摘要： A medical lavage apparatus (10) for body cavities, comprises a housing (20) having parallel irrigation and aspiration cylinders (28, 32) with plungers (24, 26) extending in bores thereof from a first end and aspiration and irrigation check valves positioned in parallel, smaller, offset, valve cylinders (46, 48) located at second ends. A septum (50) formed of intersecting semi-circular-in-cross-section baffles joins the adjacent outer ends of the irrigation and aspiration check valve cylinders so as to allow full fluid streams flowing from these outer ends to flow together at an angle. An oblong-in-cross-section, funnel-shaped, common exchange tube (22) is attached to the housing surrounding ends of both the irrigation and aspiration check valve cylinders and the septum. Inlet and outlet ports (42 and 44) are respectively positioned on the sides of the irrigation and aspiration cylinders with appropriate check valves located therein for coupling respectively to supply and waste containers (12, 16). When either of the plungers is fully inserted into its respective cylinder, a seal (80) on the end thereof covers the respective inlet or outlet port, thereby making that cylinder inoperative so as to avoid undesired fluid mixing between cylinders.

摘要： An indwelling urethral catheter (10) includes a flexible catheter drainage shaft (18) defining a drainage canal with a valve (32) mounted therein. The catheter is mounted in a urethral canal by means of a bladder-located Foley-type balloon (22) and an inflatable balloon lead shaft (24) which extends along the catheter drainage shaft. The valve (32) is normally biased to a closed position, but is actuatable to an open position by external hand manipulation of a penis in which the catheter is implanted. The catheter (10) also includes a discardable sleeve (12) which is severably attached to the distal end of the catheter (10), on the proximal side of the balloon (22). After insertion into the urethra, the balloon (22), and its lead shaft (24) are inflated through a "basketball" type contraction valve (44). Gentle traction is then applied axially to a catheter sleeve head (46) to sever the sleeve from the remainder of the catheter (10) so that it may be withdrawn from the urethra and discarded, leaving the remainder of the catheter (10) in a position whereby the most proximal end does not extend to the penile meatus.

摘要： A method and apparatus for transcribing composite images. In one embodiment, a method comprises projecting a first image onto a surface, wherein a first coordinate system defines positions within the first image and a second coordinate system defines positions on the surface. The method further comprises forming a second image on the surface by using a stylus, and recording the formation of the second image relative to the first image by periodically detecting the position of the stylus relative to the second coordinate system by receiving and processing signals transmitted from the stylus. The method also comprises translating the position of the stylus relative to the second coordinate system to a position relative to the first coordinate system, and storing the composite image comprising the first image and the second image as machine-readable data.
