    摘要: Apparatus and technique for monitoring physiological parameters. An acoustic sensor or microphone is placed in close proximity to the chest of a patient having one or two prosthetic heart valves. These heart valves produce clicks characteristic of opening and closing action. The acoustic sensor picks up the sound of these clicks and transfers them as electrical energy to a transmitter unit. The transmitter unit processes the analog signal, converts it to a digital signal and establishes the key timing factors involved. This digital data is stored in a memory buffer within the transmitter. Subsequently, this information is modulated and placed on telephone lines for transmission to a central monitoring site. At the monitoring site a demodulator returns the data to baseband digital signals. A computer at the central monitoring site displays the information in the time domain and also converts the information for display in the frequency domain.

    摘要: An ultrasound scanning system including an array of ultrasound transducers and a transporter for moving the transducers over a human back. The movement of the ultrasound transducers define a plane and a position transducer produces a position signal representative of the position of the ultrasound transducers in the plane. There is a means for producing a range signal representative of the distance between the transducers and the objects imaged in the back. The range signals are digitized and stored in an array in a digital memory with the position of each stored range signal in the array corresponding to the position of the transducer from which the range signal was obtained in the plane at the time the range signal was received. The range information is printed on a page or displayed on a cathode ray tube with the position of the printed data on the page or the data displayed on the cathode ray tube corresponding to the position on the plane of the back from which the data was obtained.

    摘要: An electrotransport device (20) for delivering one or more therapeutic agents through the skin includes electrodes (30,32) for contacting the skin (34), at least one electrode containing the agent, a power source (22) for generating electrical current (IL) for delivering the agent, a current generating and controlling means (24), and a disabling means (26) for permanently and irreversibly disabling the current. The disabling means (26) may include a timer means (66), a counter means (82), or a body parameter sensor (134) and limit comparator (132) to effect permanent disabling. The disabling means may be a permanent transition to a disabled logic state, a permanent discharge of a power supply source (22), or a permanent diversion of electrotransport current from the electrodes (30,32), or a combination of the above. The permanent disabling means may include a circuit connection means (304,308,326,328) having a frangible conducting member (332) which permanently fractures and causes an irreversible open circuit in the connection to the electrodes (334,342) upon removing a disposable/single use electrode assembly (300) from a reusable portion of an electrotransport device.

    摘要: An electrically powered iontophoretic delivery device is provided. The device includes a pair of electrode assemblies (41, 43) and a source of electrical power (30) connected thereto. Circuitry (60) is provided including an activation circuit (62) and a power generating circuit (70). Before use, neither the power generating circuit (70) nor the activation circuit (62) draw current from the power source (30). When the device is placed on the body (50) and electrical contact is established between the two electrode assemblies (41, 43), the activation circuit (62) is closed causing the power generating circuit (70) to be activated, thereby activating the device. The circuitry (60) improves the shelf-life of the device by minimizing current drain from the battery (30) before use.

    摘要: An electrotransport delivery device (410) includes control circuitry for discontinuously delivering a beneficial agent (eg, a drug) through a body surface (eg, skin 400). For example, the device may be the type which is manually activated by the patient or other medical personnel to activate electrotransport drug delivery. Once electrotransport delivery has been activated, a timer (221) counts a transition interval, typically about one minute, during which the device is allowed to operate and the impedance of the body surface (400) is allowed to stabilize. Thereafter, the electrotransport current and voltage are then monitored and compared to predetermined limits. Allowing for the transition interval permits tighter tolerances in monitoring the applied current.
