Patent number: 11813053Abstract: A method and system for monitoring neuromuscular blockade in patients during surgical procedures. A stimulator provides stimulation to a nerve of the patient, such as train-of-four (TOF). Following such stimulation, the system and method creates a predicted recovery trend for the patient that is based upon measured recovery trend and a recovery model. The recovery model estimates a recovery trend for the patient based on initial model parameter values. The recovery model creates a predicted recovery trend that is used to estimate a recovery time for the patient. The trend values from the patient are monitored and compared to the predicted trend values throughout the operation as long as the NMT measurement is on. During recovery, the recovery model and recovery time estimates are updated based on the recovery trend being formed from measurements of the patient.Type: GrantFiled: August 9, 2019Date of Patent: November 14, 2023Assignee: GE Precision Healthcare LLCInventors: Helena Liisa Anneli Batsman, Kimmo Henrik Uutela, Markku Erik Spoof

Patent number: 11298087Abstract: A method of predicting physiological alarm frequency by patient monitors includes collecting patient monitoring data of multiple patients in at least a first healthcare environment, and then determining an alarm rate model based on the patient monitoring data, wherein the alarm rate model describes alarm rates at a range of alarm configurations in the first healthcare environment. Initial alarm rate data is collected for a second healthcare environment, wherein the initial alarm rate data includes at least one alarm rate at at least one known alarm configuration within the range of alarm configurations. An alarm rate transform is then calculated for the second healthcare environment comparing the initial alarm rate data for the second healthcare environment to the alarm rate model.Type: GrantFiled: November 21, 2019Date of Patent: April 12, 2022Assignee: GE Precision Healthcare LLCInventors: Erno Petteri Muuranto, Kimmo Henrik Uutela

Patent number: 10172526Abstract: The system and method of the present application includes a physiological sensor and a motion sensor connected to a patient. The physiological sensor detects patient connection to the sensor and collects a physiological signal while connected. When the physiological sensor is disconnected, the motion sensor data is analyzed. Patterns of sensor connection and patient movement typical for nurse initiated removal compared to accidental or patient initiated removals are created. The alarm protocol may be modified if the disconnection is due to patient movement. The detected movement patterns may include movement measurements that are close to the sensor that detects how the actual disconnection happens, or general movement information for the patient such as whether the patient has been still or has moved before the sensor gets disconnected. By using this information to classify the reason of the sensor removal, a more relevant alarm may be generated.Type: GrantFiled: April 28, 2016Date of Patent: January 8, 2019Assignee: General Electric CompanyInventors: Kimmo Henrik Uutela, Matti Veli Tapani Huiku, Emma Elina Ikonen

Patent number: 7038601Abstract: The invention relates to a method and apparatus for suppressing interference in an electric signal, particularly for suppressing interference in an electrocardiogram (ECG) signal in connection with magnetic resonance imaging (MRI). In order to improve the accuracy of the suppression, the electric signal is first sampled at a high sampling frequency, whereby a first sequence of samples is obtained. Some of the samples in the first sequence of samples are then selected on the basis of predetermined criteria. The first sequence is then downsampled using the selected samples, whereby a second sequence of samples is obtained. The second sequence forms a digital presentation of the electric signal in which the interference is suppressed.Type: GrantFiled: November 26, 2003Date of Patent: May 2, 2006Assignee: Instrumentatium Corp.Inventors: Kimmo Henrik Uutela, Tor Börje Rantala, Juha Petri Virtanen
