Abstract: A surgical fluid transfer apparatus for passage of fluids includes a hub defining a longitudinal axis and having an internal chamber, an elongated member extending from the hub and a closure valve disposed within the internal chamber. The closure valve is adapted for movement between a first position substantially sealing the internal chamber to prevent passage of fluids and a second position establishing a fluid passage within the hub to permit passage of fluids therethrough. The closure valve includes a valve housing and a seal member. The seal member has an open condition establishing an internal passage different than the fluid passage to permit passage of an access instrument through the closure valve and a closed condition in the absence of the access instrument. The inner wall portions of the valve housing cooperate with the seal member to permit the seal member to assume the closed condition thereof.

Abstract: An apparatus for selectively enabling power including a power supply, and a device having a controller and an input activated by a user. The controller is selectively powered by the power supply. While the device is in a sleep state, a sensing circuit senses activation of the input by the user and enables the power supply to provide power to the controller in response to the sensed activation of the input by the user. A latch circuit causes the power supply to continue to provide power to the controller. The controller is responsive to the sensed activation of the input by the user for enabling the latch circuit and for disabling the latch circuit, thereby reentering the device into a sleep state.

Abstract: Disclosed is an ECG electrode lead wire connector which provides improved electrical and mechanical coupling of the ECG electrode press stud to the lead wire, provides enhanced ergonomics to the clinician, and may alleviate patient discomfort associated with the attachment and removal of ECG leads. The connector may be engaged and disengaged with little or no force imparted to the patient or the ECG pad, which significantly minimizes the risk of inadvertent dislodgement of the pad. In one embodiment the disclosed connector provides a thumb cam lever which affirmatively engages the press stud to the connector, and provides tactile feedback to the clinician that the connector is properly engaged. In other embodiments, the connector provides a pushbutton to enable the clinician to easily engage and disengage the connector from the ECG stud. The disclosed connectors may also decrease clinician fatigue, and may provide more reliable ECG results.

Abstract: A safety shield incorporating a locking clip to prevent inadvertent sticks or punctures by a needle is provided. The needle can be a needle cannula or other piercing member, disposed in a sliding orientation in the safety shield, such that the needle slides within the locking clip between an aperture at a proximal end of the locking clip and a trigger hole at a distal end of the clip. Upon withdrawal of the needle after use, a binding orientation is triggered when the needle tip is withdrawn from the trigger hole. As further protection to the bi-directional lock afforded by the binding orientation, the needle is provided with a safety stop to prevent movement of the needle tip through the aperture. In other aspects, the safety shield includes a trigger bushing, in which the needle cannula is slidably received, that is sized larger than the aperture.

The metal cannula is supported on a distal end of the needle hub, where the metal cannula defines a fluid flow path into the distal end of the needle hub. The plastic tip member is connected to a distal end of the metal cannula, where the plastic tip member defines a fluid flow path into the distal end of the metal cannula. Plastic tip further includes a channel groove that runs along the length of the plastic tip to allow fluid to flow into a distal end of the metal cannula. Additionally, the plastic tip member is configured to pierce a septum of a vial.

Abstract: A needle assembly is able to collect a sample of biological material in a needle of the assembly. The needle assembly has a safety shield capable of being moved on the needle assembly to cover a sharp tip of the needle assembly. The shield can be locked in place over the sharp tip by a locking mechanism. The assembly further includes an obturator that can be inserted into the needle to remove the sample from the needle. A reset member, which in some embodiments is associated with the obturator, is capable of operatively engaging the locking mechanism to release the locking mechanism and allow the shield to be moved away from the sharp tip.

Abstract: Certain embodiments of the present invention include a male luer connector having a valve arrangement for keeping a passage that extends through the male luer connector closed when the male luer connector is not attached to a corresponding female luer connector. This passage of the male luer connector may opened by connecting the male luer connector to a female luer connector. The valve arrangement of the male luer connector may include a movable sealing element arranged around a central fluid conduit. In some embodiments, the male luer connector may include a filter that is permeable to gas, but substantially impermeable to liquid, thus allowing gas to be purged from the male luer connector while substantially preventing liquid from leaking from the connector at least when the male luer connector is not connected to a female luer connector.

Abstract: A medical valve device includes a valve unit. The valve unit includes two fluid channels and is positionable to selectably connect two inlet ports and an outlet port such that in one position, fluid introduced at a first inlet port is caused to flow in a first fluid channel to a second inlet port and thence in a second fluid channel from said second inlet port to said outlet port.

The locking clip is positioned and configured to obstruct rotation of the locking member after the needle has been retracted within the housing to obstruct re-advancement of the needle.

Abstract: A cassette of tympanic thermometer probe covers includes a frame and probe covers releasably attached to the frame. The probe covers can be individually attached over a probe of a tympanic thermometer to protect the probe from contamination. The probe covers are constructed to releasably secure themselves to the probe. The force required to secure the probe covers to the frame is less that the force which is required to detach the probe covers from the frame so that the probe cover is held by the frame while being attached to the thermometer probe. The probe cover is connected to the frame by frangible connections that are arranged to inhibit pivoting of the probe cover when being attached to the thermometer probe. A method of securing a probe cover to a probe of a tympanic thermometer is also disclosed.
