摘要： A blood pressure determining apparatus is provided which applies oscillations to the blood vessel of a subject through an exciter to determine the blood pressure based on the frequency of the oscillations propagated through the blood vessel measured by an oscillation sensor. The apparatus monitors an output of the oscillation sensor when the exciter applies no oscillation to the subject to determine the power spectrum of noise signals contained in the output and sets the frequency of oscillations to be applied to the blood vessel to any value within a band of the power spectrum in which the power of noise is small. This enables the blood pressure to be determined without influence of any electric disturbances from peripheral devices.

摘要： An ultrasonic Doppler blood flow meter apparatus includes a wall filter for eliminating clutter from an echo signal of an ultrasonic pulse signal sent to a living being under test. The wall filter includes a switch for cutting a part of input data and a control unit for controlling the switch such that the switch is opened during a period in which first m data (where m is integer) is inputted to undergo filtering by the wall filter while the switch is closed during a period in which data following the (m+1)-th data inclusive thereof are inputted.

摘要： A beam former for a ultrasonic diagnostic apparatus is arranged to have low-bit analog-to-digital converters and enables to obtain an excellent echo signal from blood flow. The beam former further includes a sample and hold circuit for sampling an echo signal of a pulse reflected from the inside of a human body. A delaying circuit serves to delay the output of the sample and hold circuit by a delay time corresponding to an integer multiple of a transmitted pulse period and is subtracted from the output of the sample and hold circuit. The subtracted output is analog-to-digital converted and is stored in a memory. The memory reads out the data asynchronously with the storage. The delaying circuit is composed of an analog-to-digital converter, a memory and a digital-to-analog converter and has a delay time corresponding to an integer multiple of the transmitted pulse period.

摘要： A channel control mechanism for a microchip has a laminated structure formed of members including elastic members, and includes: a sample reservoir for packing a sample therein; a reaction reservoir in which mixture and reaction of the sample are performed; and a channel formed in a middle layer of the laminated structure, for bringing the sample reservoir and the reaction reservoir into communication with each other. The channel control mechanism performs the reaction and analysis in such a manner that the sample is delivered into the reaction reservoir through the channel. A shutter channel (pressurizing channel) is provided in a layer different from a layer in which the channel is formed so that the pressurizing channel partially overlaps the channel. The channel is closed through applying a pressurized medium to the shutter channel (pressurizing channel), and the channel is opened through releasing a pressure of the pressurized medium.

摘要： A technology for performing the filter processing of blood flow velocity data having aliasing by only common filter processing means and common addition and subtraction means and actualizing image display of smooth blood flow velocity is disclosed. According to this technology, when performing image display of the blood flow velocity of blood within a subject biological body using an ultrasonic wave Doppler method, the difference values of data D33 of an arbitrary focus point and data D32 and D34 of points spatially prior and subsequent to this focus point are calculated in the pre-processing unit (difference calculating unit) 41. Then, in the filtering unit 42, after filter processing is performed on these difference values, data D39 after filter processing and data D33 of the arbitrary focus point are added in the post-processing unit (addition processing unit) 43. In this way, a filter processing can be performed under the assumption that the velocity difference is smaller than the velocity difference generated by the aliasing phenomenon, and filter processing of the blood flow velocity value in the sound ray direction of the ultrasonic waves can be performed without being influenced by aliasing.
