20090041821Cleaner for medical probe - Cleaning of a medical probe is provided by a gel layer deposited on a carrier to form a cleaning element. The gel has a tacky surface and is impregnated with a disinfecting agent. After contacting the patient's body surface, the medical probe surface is cleaned by pressing it against the gel surface. The soiling particles that were carried by the probe will be adhered to a gooey layer. The used cleaning element is discarded after cleaning.02-12-2009
20100030099Medical Probe With Consistent Action - A probe for intermittent contacting a patient body with a predetermined speed and force. Initially, the probe is recessed inside the device which is brought in contact with the patient body, while keeping the probe from making a contact with the patient. On a command from an operator or control circuit, the probe is deployed moving toward the patient body surface with a substantially consistent force and rate of motion, thus making a contact in a consistent fashion.02-04-2010
20100106029ARTERIAL BLOOD PRESSURE MONITOR WITH A LIQUID FILLED CUFF - A non-invasive arterial blood pressure monitor uses an inflatable cuff that incorporates the first bladder that is filled with non-compressible liquid or gel. The bladder can be pressurized by an action of a pressurizing device superimposed onto its outer surface. In a preferred embodiment, a pressurizing device is an air-filled second bladder being connected to an air pump and bleed valve. The first bladder is positioned between the patient's body and the second bladder. During operation, the second bladder compresses the first bladder, which, in turn, compresses the patient's artery against the supporting bone. The mechanical coupling between the blood-filled artery of a patient and the liquid-filled bladder of a dual-bladder cuff is improved for detecting pressure oscillations in a broad frequency range. The pressure sensor that is coupled to the first bladder also functions as a hydrophone for picking-up the mechanical oscillations from any part of the occluded limb or digit. This allows for improved computation of the arterial pressure.04-29-2010
20100122629Triboelectric air purifier - Air purifier containing an air blower and a rotating brush, such brush having long flexible bristles made of a material that is capable of developing negative triboelectric charge. During a part of the rotation cycle, the bristles move across a surface that can accumulate a positive charge. This cause the bristle to charge negatively. The air impurities are attracted to negatively charged bristles and discharged into a collecting bin.05-20-2010
20110110395MULTI-SITE ATTACHMENTS FOR EAR THERMOMETERS - A thermometer that enables the measurement of temperature from multiple body sites comprising a body portion that has a circuit configured to measure an IR signal and convert it into an output that accurately reflects body temperature and a switch in communication with the circuit. The thermometer also comprises a probe that has an IR window configured to accept an IR signal and an attachment mechanism coupled to the probe which comprises a generally circular hollow bore at its distal end, fastening members to engage the body of the thermometer and a pin at its proximal end for interacting with the switch on the body of the thermometer. When the attachment mechanism couples to the probe, the pin interacts with the switch in various positions and the circuit converts the signal based upon the position of the switch which position reflects the location from which the temperature measurement was taken.05-12-2011
20110134962PROBE COVER WITH MATCHING FEATURE FOR A MEDICAL THERMOMETER - A probe cover for medical thermometer has a matching feature for preventing its use with an incompatible thermometer. A mechanical matching feature of the probe cover includes at least one of a fold, a step, or a series of holes or indentations that are respectively matched to a ridge, a valley or series of pins formed on the front end of a compatible thermometer. When applied to the compatible thermometer, the mechanical matching feature permits the probe cover to be fully seated on and retained by the probe, thereby placing the thermometer in condition for use. Alternatively, an opto-electronic matching feature of the probe cover includes a reflective layer for use with an opto-electronic detection circuit of a compatible thermometer. When applied to the compatible thermometer, the opto-electronic detection detects the reflective layer and places the compatible thermometer in an operational state for use.06-09-2011
20110137201ORAL THERMOMETER WITH CURVED PROBE - An oral thermometer including a probe for insertion into the mouth of a user. The probe includes and an elongate first stem, a joint stem extending the first stem and disposed at a first angle to the first stem, and an elongate second stem extending from the joint stem and disposed at a second angle to the joint stem. The first angle open down and the second angle open up. The second stem includes a probe tip at a distal end thereof that is configured to be inserted into the mouth of a user. In operation the thermometer is operable to heat the probe tip to a pre-warmed temperature, detect an elevated temperature higher than the pre-warmed temperature when inserted in a user's mouth, and initiate a temperature reading upon detecting the elevated temperature.06-09-2011
20110228811NON-CONTACT MEDICAL THERMOMETER WITH STRAY RADIATION SHIELDING - A non-contact infrared (IR) thermometer for measuring temperature from the surface of an object includes an IR radiation sensor attached to a heating element and a thermal shield having an interior surface positioned within the sensor's field of view that has a high emissivity. An electronic circuit controlling the heating element maintains the temperatures of the sensor and shield substantially close to an anticipated surface temperature of the object. The IR radiation sensor is further thermally coupled to a reference temperature sensor. An optical system positioned in front of the shield focuses thermal radiation from the object on the surface of the sensor, while the shield prevents stray radiation from reaching the sensor. Signals from the IR and reference sensors are used to calculate the object's surface temperature.09-22-2011
