    摘要: An apparatus for monitoring whether or not a distal end of a tube is positioned inside a blood vessel includes a heating element configured to heat the tube distal end, and a sensor arrangement configured to generate a measurement signal indicative for heat transferred by exterior of the distal end. The apparatus further includes a comparator configured to compare the measurement signal with a reference level. The reference level equals a value attained by the measurement signal in response to a minimum flow velocity in the blood vessel. Further, a system is configured to exchange a liquid with a mammal via a blood vessel. The system includes the apparatus having the tube.

    摘要: An electronic capsule (100) is provided. The capsule (100) has a discrete drive element (300) comprising: a housing (109), electronics for making the electronic capsule (100) operable, a pumping mechanism (115) for dosing and displacing a substance, a power source (105) for powering the electronic capsule (100) and enabling the electronics and the pumping mechanism (115) to operate, and a locking mechanism (130); and a discrete payload element (200) comprising: a housing (109), a reservoir (210) for storing the substance, one or more openings (250) in the housing (109) for releasing the substance from the reservoir (210) and a locking mechanism (230) for engaging the drive element locking mechanism (130). Engagement of the drive element locking mechanism (130) with the payload element locking mechanism (230) secures the drive element (300) to the payload element (200), thereby making the electronic capsule (100) operable and specific.

    摘要: A capsule and methodology for dispensing a medicament in the gastrointestinal tract of a mammal is disclosed, the gastrointestinal tract having tissue sites of interest. The capsule may include a medicament reservoir; medicament dispensing means such as a plurality of piezoelectric droplet jet nozzle dispensers; a power source; electronic control circuitry means and/or detecting means capable of communicating with a medicament dispensing means for regulating the amount and time interval for dispensing of the medicament into the gastrointestinal tract by the medicament dispensing means; and a non-digestible outer protective shell housing, e.g., the medicament reservoir, medicament dispensing means and electronic control circuitry means. A plurality of the nozzle dispensers of the medicament dispensing means can be positioned tangentially to a surface of the housing such that during release of a medicament, the capsule is caused to rotate and/or translate so as to discharge the medicament homogeneously onto tissue sites of interest. In addition, by using multiple nozzles and releasing medicament at high speed, this facilitates medicament absorption by the intestines in the gastrointestinal tract.

    摘要: A medical device comprising a probe for measurement temperature data of tissue within a patient's body is proposed. The probe (2) comprises a flexible substrate (3) attached to a medical device core (5), the flexible substrate (3) comprising one or more thermopiles (7) and may furthermore comprise resistors for measuring an absolute temperature and heat sources for locally applying heat. The thermopiles can be processed directly on a flexible polymer carrier or, alternatively, on a silicon substrate and transferred to a flexible carrier (3) enabling both, a highly flexible substrate (3) and very small structural dimensions for the thermopiles (7) and, possibly, the resistors and heat sources. Accordingly, measurement of temperature gradients of tissue being in contact to the medical device may be performed at high resolution allowing reliable detection of temperature anomalies e.g. due to malign tissue.
