  • Publication number: 20230417714
    Abstract: A data processing device performs a data process on a measured waveform obtained by a prescribed measurement of a sample. The data processing device includes an estimator, a calculator, and a display processor. The estimator estimates a predictive distribution of each peak shape for a corresponding one of a plurality of peak waveforms using a prescribed peak shape model, the plurality of peak waveforms being included in the measured waveform and being close to each other. The calculator calculates a predictive distribution of a quantitative indicator for each of the plurality of peak waveforms based on the predictive distribution of the peak shape estimated by the estimator. The display processor is operable to display the predictive distribution of the quantitative indicator calculated by the calculator.

  • Patent number: 11850409
    Abstract: A medical needle includes a needle portion (10) having a needle tip on a distal end, a case (30) configured to be capable of accommodating the needle portion that can be exposed from the distal end side, a movement mechanism (50) for moving the needle portion inside the case, and a movement restricting portion (37) that restricts the needle tip accommodated in the case from moving in a direction opposite to a moving direction of the needle portion. The movement restricting portion maintains the needle tip accommodated in the case such that the needle tip can come into contact with an inner face of the case to restrict the movement of the needle tip in the opposite direction.

  • Publication number: 20230304975
    Abstract: An acquirer that acquires, based on measurement data acquired over time using an analysis device, measurement waveform data, the measurement data representing a change in domain direction of the measurement data, and an estimator that acquires estimation waveform data that is what noise data is at least partially removed from the measurement waveform data, are included. The estimator acquires the estimation waveform data as data such that the noise data included in the measurement waveform data has a correlation in the domain direction. Thus, a peak shape can be correctly estimated based on measurement waveform data to which noise is added.

  • Publication number: 20220382834
    Abstract: An analysis method for analyzing a sample includes a first step of acquiring measurement data including a first signal based on the sample and a second signal based on noise added to the first signal as a result of analysis of the sample, a second step of assuming a shape representing the first signal and a shape representing the second signal and modeling the measurement data using Bayesian inference, and a third step of estimating a probability distribution of characteristics of the sample based on the modeled measurement data.

  • Patent number: 11423331
    Abstract: This analytical data analysis method uses machine learning of analysis result data (31) measured by an analyzer (1), and includes generating simulated data (32) in which a data variation has been added to the analysis result data (31) within a range that does not affect identification, performing the machine learning using the generated simulated data (32), and performing discrimination using a discrimination criterion (23b) obtained through the machine learning.

  • Patent number: 10603447
    Abstract: In a safety apparatus for medical needles, when leg portions are extended from a first folded position to a second extended position, a distal end of a needle is introduced into a space of a shield member connection hub, and a first blocking wall and a second blocking wall overlap so as to block the cross section of the space to form a double blocking wall and blocks the cross section of the space. The double blocking wall is capable of preventing the distal end of the needle from moving downward from the double blocking wall and preventing the distal end of the needle from being exposed to the outside of the apparatus.
