A portable power station including a current, light, and voltage sources as well as a control panel to permit a user to selectively operate the current and light sources. A housing contains the sources and is suitable to contain a main power source that has positionally fixed and polarized power terminals. The housing includes positionally fixed attachment posts to which the polarized conductors of the sources are electrically connected, and which are suitable for electrical connection of the polarized power terminals of the main power source.

Methods and systems are provided for modifying a fluid for oral administration. Typical systems include a reservoir which contains or may be filled with water or other aqueous components. The systems also include a container or retention pocket which is integral with or mountable on or in the reservoir. The container holds a soluble beneficial agent, typically an electrolyte, a nutrient or a medicament. The container is adapted to selectively combine a measured amount of the beneficial agent with the aqueous component based upon patient need.

An intradermal delivery device for delivery a substance into the skin of a patient has a fluid chamber for containing the substance, at least one micro skin penetrating member, and a valve controlling the flow of the substance from the fluid chamber to the micro skin penetrating member. An adhesive releasably attaches the device to the skin of the patient, the fluid chamber can be sized to hold a unit dose of the substance, and, in some embodiments, the fluid chamber can be releasably coupled to a housing of the device.

A needle shield and needle shield assembly are provided for preventing accidental needle sticks. The needle shield includes opposing sidewalls and is pivotable between an open position that allows use of the needle cannula and a closed position that covers at least the tip of the needle cannula. A locking member extends from one of the sidewalls of the needle shield and includes a relatively rigid base portion and a relatively flexible end portion. The needle cannula engages the relatively flexible end portion when entering the needle shield cavity, deflecting it with respect to the base portion. Upon any attempt to move the needle shield from the closed position to the open position, the needle cannula is directed by the locking member towards the relatively rigid base portion, thereby making it very difficult to reuse the needle cannula.

A safety needle assembly has a needle hub and a needle cannula projecting from the hub. Wings project transversely from the hub to facilitate manipulation and positioning of the needle assembly. A shield is hingedly attached to the needle hub and can be rotated from a first position where the needle cannula is exposed to a second position where the needle cannula is shielded. At least one latch may be disposed on the shield for secure locked engagement with the hub, the wings and/or the tubing extending from the hub. A spring may also be provided for propelling the shield into the second position.

Systems and methods for measuring saliva sodium concentration using a chromatographic reaction enable rapid-results, low-cost diagnosis of various medical conditions in an outpatient setting. In one embodiment, measured patient saliva sodium concentration is used by the patient or the patient's healthcare provider to guide medical decision making. In another embodiment, measured patient saliva sodium concentration is processed to mechanically adjust the concentration of sodium in an aqueous solution to be delivered to the patient for oral administration. In yet another embodiment, a closed loop system measures saliva sodium concentration and uses any of a number of different types of feedback control systems to monitor and control the fluid and/or electrolyte state of the patient.
摘要:
A pen needle (101) for use with a drug delivery device (100) includes a hub body (113) having internal threads (216) to receive the drug delivery device (100). A post (121) is connected to the hub body (113). A needle (103) is rigidly fixed to the post (121). The post (121) is separable from the hub body (113) such that the needle (103) is removed with the post (121). The fluid path is not disturbed by such removal because the entire needle (103) is removed with the post (121). Removal of only the post (121) and needle (103) reduces the volume of waste required for disposal, thereby increasing the effective capacity of a sharps container.
