Abstract: A probe assembly for an infrared medical thermometer, which is adapted for insertion into a patient's ear canal and which facilitates a rapid measurement of the patient's body temperature with very high accuracy. The probe assembly includes a plastic outer tube sized to fit snugly in the patient's ear canal, with an elongated heat sink and an infrared sensor located within the tube. A cylindrical shield and inwardly-projecting guard ring ensure that the sensor's hot junction receives radiation only from the ear canal and that the sensor's cold junction is prevented from being heated for at least sufficient time to allow the thermometer to provide an accurate measurement of the patient's body temperature.

Abstract: A self-contained handheld infrared medical thermometer having an elongated probe that is reciprocably movable between a retracted position, located fully within the thermometer housing, and an extended position, located exterior to the housing. When extended, the probe is adapted for insertion into a patient's outer ear canal to measure the patient's body temperature. When the probe is retracted within the housing, a reference plate is pivoted in front of the probe, to facilitate calibration. Advancement of the probe to its extended, operative position automatically pivots the reference plate away from the advancing probe and, in addition, automatically advances a disposable protective cover from a container for a large number of such covers into a position where it automatically stretches over the advancing probe to provide hygienic protection.

Abstract: A probe cover assembly for use in covering and protecting the elongated probe of a medical thermometer. The assembly has three laminated layers, including a flat base layer with an aperture sized to slide over the probe, an intermediate stretchable film, and a protective paper layer having radially-aligned perforations aligned with the base layer aperture. In use, the probe cover assembly is placed on the probe by inserting the probe through the base layer aperture, from the assembly's paper layer side, to stretch the plastic film over the probe, with the perforated paper functioning initially to separate the probe from the film and thereby prevent the film from initially sticking to the probe and stretching unevenly. The probe cover assembly is removed from the probe and discarded by sliding the apertured base layer along the probe, with the perforated paper functioning to scrape the stretched film from the probe.

Abstract: Apparatus for effectively ejecting a protective cover from the elongated probe of a medical thermometer, even in cases where the cover can stick to the probe surface. The probe cover, which includes a generally cup-shaped body and a resilient ring at the body's open end, is secured in place on the probe by an outwardly-projecting flange at the probe's base end, which retains the probe cover's circular ring. An ejector sleeve reciprocates between a retracted position, in which it is retracted from the elongated probe, and an extended position, in which it fully encircles the probe. A coil spring continuously biases the ejector sleeve to its extended position, but with a force nominally insufficient to free the probe cover's resilient ring from the probe's retaining flange.

Abstract: In a thermometer sheath package, for electronic clinical thermometers, two strips of thermoplastic material are sandwiched between two coated paper cover strips all joined together along a seal line in the shape of a sheath for the probe of the thermometer. The inner two strips are joined together along the seal line by a tear seal to define the sheath for the thermometer probe. The cover strips are joined to the inner strips along the seal line by peelable seals. Perforated lines are defined across the width of the cover strips near the mouth of the sheath to define tabs in the cover strips at the mouth of the sheath. The tabs of the cover strips are sealed to the inner strips in broad flat seals across the width of the cover strips. The seal line defining the sheath and along which all four strips are sealed together extends past the perforated lines and into the area of the broad flat seals.

Abstract: An electronic thermometer probe and cover assembly includes a probe extending from a handle and having limited axial movement into the handle against a resilient force. An elongated cover having open and closed ends fits over the probe. Cooperating elements on the open end of the cover and the handle snap together when the probe is moved into the handle by the cover to retain the cover in position with intimate contact between the probe end and cover. Actuation of a thumb button on the handle increases the force urging the probe out of the handle to unsnap the cover from the probe handle.

Abstract: A probe cover holding and dispensing arrangement for an electronic thermometer includes a chamber in the thermometer housing to receive a carton containing the probe covers. A tear-away flap on the carton exposes some of the covers. An aperture in the chamber, closable by a sliding cover, provides access to the exposed covers.

Abstract: The device is primarily adapted for use in hospitals and comprises a housing having a front window through which a digital display of sensed temperature is observed. The housing may receive one of preferably two probe holsters one of which has associated therewith a probe for oral use and the other of which has a probe for rectal use. Each probe holster is elongated in shape and has a passage for receiving a probe with the probe being fixedly wired into the holster so that the probe cannot be swapped between holsters. A holder is mounted on the top of the device and receives a cartridge of probe covers which are locked into the holder but are easily removed upon insertion of the probe into an individual cover. The holsters and associated probes are constructed to be autoclavable and gas sterilizable. The device is normally stored on a platform through which the batteries in the device are recharged between use of the device. The probe is of improved design and employs a thermistor sensor.

Abstract: A thermometer for temperature measurement of a body is provided wherein a temperature probe electrically connects to a temperature read-out means and a probe cover or sheath fits over such probe. The sheath has a temperature sensor e.g. a thermistor mounted thereon, which sensor is electrically connected to the probe when such probe is inserted into such sheath to provide a rapid measurement and read-out of the temperature of a body. The sheath with temperature sensor is disposable and readily replaced for the next use of the electric thermometer of the invention. Alternatively, the sheath can be sterilized for reuse.

Abstract: A temperature sensor is proposed which is intended in particular for measuring the temperature of the air aspirated by an internal combustion engine which operates by electronic fuel injection. The temperature sensor includes a carrier body receiving electrical connections and a temperature-dependent electrical resistor element which is surrounded by a protective sheath. The protective sheath has apertures which permit free access to the temperature-dependent electrical resistor element by the medium to be measured. The protective sheath is advantageously capable of being connected in a positively-engaged manner with a protruding catch of the carrier body. As a consequence of the free access of the medium to be measured to the temperature-dependent electrical resistor element, a very short response time on the part of the temperature sensor to changes in temperature is assured.

Abstract: An antiseptic guard for a clinical thermometer is formed by a sheath constituted by two synthetic resin films welded together along two lateral edges and a top edge connecting the lateral edges. A welded joint is formed at an end of the sheath spaced from the top edge to hold the tip of the thermometer in position while a bendable flap is formed between the joint and the top edge. When the sheathed thermometer is inserted in the anus, the flap is folded back and exposes smooth surfaces of the films, avoiding direct contact with weld edges and thus preventing formation of sores.

Abstract: The disclosed apparatus comprises a sheet-metal strap having a strip portion that can be threaded through a slot in the strap so that a loop is formed to encircle a temperature sensor having pipe-encircling portions extending oppositely from the loop generally as a "figure-8", providing parallel heat conduction paths between the pipe and the temperature sensor. Extremities of the strap can be drawn toward each other, thereby developing tension about the temperature sensor and the pipe; and the extremities can be folded with each other as a means for tensioning the sheet-metal member against the temperature sensor and the pipe and for securing the strap in place under tension.
