Secure medication storage and retrieval system

A fluid sample receptacle provides a means of assuring uncontaminated, multiple samples of a fluid specimen. An upper or isolated sample chamber and a lower or primary sample chamber provide redundant test samples. A cover or lid with a downwardly extending column includes a stopper with a removable plug attached to automatically seal the lower sample chamber when the cover is sealed across the top of the upper chamber. This feature guarantees that the sample chambers are sealed or isolated simultaneously and that the test samples are therefore identical when taken. Tamper evident seals prove that either sample has not been contaminated. A preferred embodiment provides a bellows assembly to accommodate variations in ambient pressure and to provide a positive means of expelling a precise quantity of fluid from the receptacle for testing.

Fluid sample receptacle

A method for dispensing a sample of liquid from a sealed thermoplastic container which includes both a volumetrically flexible chamber holding the liquid and also a plurality of spaced axially vertical nozzles on the container underside, the nozzles having an inlet in fluid communication with the chamber. The container is first manipulated to increase the volume of the chamber, rotated from a right side up position to an upside down position, and after the two preceding operations an axial opening is non-invasively created in the nozzle while the container is upside down without decreasing the volume of the chamber. The container is then rotated from the upside down position to a right side up position without decreasing the volume of the chamber, manipulated to decrease the volume of the chamber and expel a sample of the liquid from the chamber through the nozzle opening, then rotated to an upside down position and the opening in the nozzle is closed by melting and clamping it closed.

Liquid container sample transfer method and apparatus

A medication dispenser for use in a hospital or other medical setting comprises a plurality of containers for holding medication units, packaging apparatus for containing one or more medication units in a package and robotics for manipulating a selected container to transfer one or more medication units from the container directly to said package. Since medication is directly transferred from the container to the package, no cross-contamination occurs.

Medication dispenser system

A vacuum operated system for individually dispensing items of oral solid medicine from bulk storage to a user, where the medicine is dispensed under computer control, and the quantity and type of medicine is selected in advance by the user. The invention includes medicine dispensing equipment and a computer that provides a user interface. A plurality of storage containers arranged in a rotatable carousel or a rectilinear array may contain various pharmaceutical articles, or various types, dosages, ages, and lot numbers of medicines. The storage containers may be easily refilled by inserting modular refill cartridges into the storage containers. After a user enters certain data into the computer, the invention aligns a universal vacuum probe with the storage container that contains the desired items. The universal vacuum probe is lowered to the desired storage container and engaged with a container probe that is exclusive to that storage container. After a vacuum source creates suction within the universal vacuum probe and the container probe, the universal vacuum probe and the container probe are operated to individually extract items from the storage container. In one embodiment, the extracted items are dispensed into a cup for retrieval by a user. In another embodiment, one or more items are packaged separately in an envelope, which is stored in a portable envelope-organizing tote along with other envelopes containing items requested by that user.

Envelope

An apparatus for dispensing single homogeneous units upon rotation of the apparatus comprising a generally circular walled container having a bottom for holding the singular homogeneous units. A discharge area located distally from the bottom for receiving the single homogeneous units and for discharging them upon rotation of the apparatus. A helical spiraled rib member located on the generally circular walled container extending from the bottom of the container and along the circular walls of the container for creating during rotation a continuously variable inclined surface along the helical spiraled rib member and the circular walls of the container for advancing single homogeneous units along said helical spiralled rib member and the generally circular walls of the container until a single homogeneous unit reaches the discharge area for discharge from the container. The helical spiraled rib member has a helix depth from the circular wall of the container sufficient for advancing only a single homogeneous unit along the helical spiraled rib member and the generally circular wall of the container until a single homogeneous unit reaches the discharge area. The helical spiralled rib member has a helix angle sufficient relative to the length of the generally circular walled container from the bottom to the discharge area for creating during rotation a sufficient inclined surface for advancing single homogeneous units to the discharge area. Further, this invention provides removable caps which are used to seal these containers from the ambient environment when not being used for dispensing of single homogeneous units.

A resealable conduit is used to remove or add fluid to a closed system without coring or contamination of the fluid. The conduit can include funnel-shaped guide means, duck bill valve means and beveled tip puncturing means. A conduit resting angle of less than about five degrees can be achieved. A tip bevel angle between about ten and twenty degrees is preferred. The beveled tip can have a rotated or twisted blade surface extension. A blade surface extension formed with a ninety degree rotation of the blade surface is preferred. Alternately, the puncturing means can include a needle point or a flat cutting surface.

Disclosed herein is an automatic allergy testing system. The system includes an electrode capable of testing up to eight different allergies and an associated electronic unit. The electrode includes apparatus to transcutaneously deliver an allergen to the patient without puncturing the patient's skin. The electrode also includes a temperature sensor for sensing the skin temperature in the area surrounding the delivery of the allergen. Electronic apparatus is provided for processing the sensed temperature and storing data related thereto for subsequent print out to an output device. The allergy testing system is controlled so that periodic temperature readings are made at thrity second intervals over approximately a fifteen minute testing span. The data can be printed out in a graphic format to allow the physician to easily and quickly make more accurate diagnosis.

Automatic allergy detection system

Disclosed herein is an electrode for performing a plurality of allergy tests on a patient undergoing tests. The allergy electrode consists of a plurality of individual testing electrodes and a single common electrode. Each of the testing electrodes includes allergen delivery apparatus and a temperature sensor. The allergen is contained in a removable allergen impregnated pad. If a dry allergen is used, it may be hydrolized with a drop of distilled water prior to application. A small electric charge charges a charge plate on one side of the allergen pad and a common ring on the electrodes is grounded in circuit with the charging plate, thereby causing electric field to transfer the allergen through the pores of the skin. The area surrounding the allergen delivery area is sensed for temperature by a thin film temperature sensor and a rigid temperature conducted base. A thermistor or other temperature to voltage transducer converts the sensed temperature to an electric voltage which is applied through appropriate differential amplifiers and multiplexer to an analog to digital converter. The digital data is then stored by a microprocessor in random access memory. An output device can be connected to receive the stored data and the time at which it was stored so as to manifest to the physician the change in temperature of the tested area with respect to time.

Electrode for non-invasive allergy testing

Described herein is a controlled circulation incubator device having a plurality of plate receiving trays held by a tray bracket. Heated air is circulated by a blower and heater assembly around the trays held by the tray bracket and the temperature of the flowing heated air is sensed by a thermister included in a temperature controller circuit. The termister is coupled in a circuit so that its resistance determines the amount of heating provided by the heater portion of the blower and heater assembly. Each of the trays have a front lid and a back lip and the plurality of trays are offset from one another within the confines of the incubator device. The angle of the back lip and the amount of offset are selected so that each of the back lips are positioned in a generally planar surface. This causes the front lip, which extend at a slight angle from the receiving trays, to extend into the circulating air stream and air is forced between adjacent trays to heat the contents held by the trays. At the backside of the trays a low pressure area appears, further forcing air across the trays. The package of the incubator is fabricated of metal to promote heat loss so that the heating means can more accurately control the temperature. A variable resistor is included to allow different temperatures to be selected.

Controlled circulation incubator

The test apparatus detects pressure changes in a vessel containing a volume of a contaminated industrial liquid and a volume of gas. The apparatus includes a detector having a housing defining a chamber. A pressure transducer having a flexible, pressure-transmitting wall is mounted in the chamber. A passageway fluidly communicates between a port in the housing and the transducer. In one embodiment a needle housing is removably coupled to the port. A hollow needle is adapted to pierce a stopper in the vessel. The vessel remains continuously sealed during and after the pressure test. Pressure changes in the gas of the vessel are transmitted through the needle and the passageway to the transducer. The transducer converts such pressure changes into corresponding electric signals which are indicative of the density of organisms in the liquid contained in the vessel. In another embodiment, the gas in the vessel is coupled to a pressure-responsive, threshold switch for detecting when the gas in the vessel reaches a threshold pressure.
