摘要： A differential pressure based flow sensor assembly and method of using the same to determine the rate of fluid flow in a fluid system. The sensor assembly comprises a disposable portion, and a reusable portion. A flow restricting element is positioned along a fluid flow passage between an inlet and an outlet. The disposable portion further has an upstream fluid pressure membrane and a downstream fluid pressure membrane. The reusable portion has an upstream fluid pressure sensor and a downstream fluid pressure sensor. The upstream fluid pressure sensor senses the upstream fluid pressure at a location within the fluid flow passage between the inlet and the flow restricting element. The downstream fluid pressure sensor senses the downstream fluid pressure at a location within the fluid flow passage between the flow restricting element and the outlet. The process utilizes output of the sensors to calculate the flow rate of the fluid.

摘要： An oximetry probe assembly includes fluid seal assembly taking the form of a manually actuated plunger which moves relative to a barrel having a seal placed therein. Depression of the plunger causes the seal to be deformed so as to permit insertion of an oximetry probe through the seal and advancement towards a central venous catheter. When the plunger is released, the seal is compressed against the barrel and the sheath of the oximetry probe to thereby form a fluid-tight seal. The plunger and barrel are preferably configured as a one-handed grasping assembly whereby the user may hold the plunger and barrel with one hand, press the plunger with the thumb, and advance the oximetry probe through the fluid seal assembly with the other hand.
摘要翻译：血氧测定探针组件包括采用手动致动柱塞的形式的流体密封组件，其相对于具有放置在其中的密封件的筒移动。柱塞的凹陷导致密封件变形，从而允许血氧测定探针插入密封件并朝向中心静脉导管前进。当柱塞被释放时，密封件被压靠在枪管和血氧测定探针的护套上，从而形成流体密封。柱塞和筒体优选地构造为单手握持组件，由此使用者可以用一只手握住柱塞和筒，用拇指按压柱塞，另一只手推进血氧测定探针通过流体密封组件。

摘要： A single lever control for the throttle and clutch of a marine propulsion device including a housing pivotally supporting both a main control lever and an auxiliary warm-up lever, a throttle lever, and a gear shift lever. The throttle lever is alternately operable to regulate the setting of a remotely located engine throttle in response to movement of either the main control lever from a neutral position or the warm-up lever from an idle position. The gear shift lever is operable to shift an engine clutch in response to initial movement of the main control lever from the neutral position. A lock-out lever mounted inside the housing cooperates with a lock-out plate carried by the warm-up lever and with a recessed, arcuate surface on the gear shift lever to prevent movement of warm-up lever when the main control lever is displaced from the neutral position and to prevent movement of the main control lever when the warm-up lever is displaced from the idle position. In one embodiment, the locking arm of a locking mechanism carried by the main control lever cooperates with a notched index plate mounted on the exterior of the housing and coaxially with the control lever pivot axis to releasably lock the main control lever in the neutral position. In another embodiment, the index plate and the control lever are arranged to afford selective adjustment of the angular orientation of the main control lever so it will be substantially vertical when in the neutral position irrespective of the angular orientation of the housing to the horizontal.

摘要： A valve including a substantially rigid cannula and a valve member positioned for operable communication with the cannula. The valve member is formed from a substantially resilient material, having a slit extending therethrough, and movable with respect to the cannula between a first closed position and a second open position. The slit is substantially closed by the resiliency of the material of the valve member when the valve member is positioned in the first closed position and the cannula cooperates to extend through the slit during movement of the valve member from the first closed position to the second open position to establish a fluid flow path through the cannula and the valve member. A sealing member is also provided independent from a flow of fluid within the fluid flow path to provide positive sealing of the slit when the valve member is positioned in the first closed position.

摘要： An apparatus for facilitating assembling a length of flexible tubing on a component part which avoids the use of sealing solvents yet affords a secure placement of the tubing thereon. The apparatus and method assures a secure fitment by stretching the tubing to a predetermined dimension which is larger than the outside dimension of the portion on which the tubing is to be placed on the component part, and while in such a position the tubing is temporarily frozen by means of a coolant. An important feature in stretching the tubing to the enlarged dimension is in assuring that it is done in a uniform manner and that the stretched walls are substantially parallel to each other. This is effected by utilizing a parallel motion of jaw members which are placed within the tubing to stretch it to its expanded state. With the tubing frozen in the expanded state, it is then placed on that portion of the commodity as it normally would be and the tubing allowed to return to room temperature whereby it will attempt to assume its original diameter.

摘要： A washing apparatus for small parts which will permit the loading of the parts into the apparatus in a fast and efficient manner and at the same time will afford maximum cleaning of the parts. The particular component parts for which the machine is specifically designed are utilized in the fabrication of intravenous solution administration sets. The washing apparatus includes a plurality of basket members which are pivotally carried by a rotatable carrier member. The baskets are pivoted in such a manner in conjunction with the apparatus that they can be extended outwardly for emptying purposes, yet are locked into the carrier so that the parts are retained therein. A spray system is also provided in the washing apparatus so as to afford maximum cleaning of the parts as well as a rinsing of the washing solution with subsequent drying.
