DEVICE AND METHOD FOR ALTERNATELY MEASURING THORACIC PRESSURES AND FOR SEALING OESOPHAGEAL SECRETION
20230191054 · 2023-06-22 ·

The present invention relates to a device and a method for alternately measuring the thoracic and pleural pressure and for gastropharyngeal or tracheal sealing, wherein the balloon component of a tube or catheter placed in the trachea or oesophagus alternates between two filling or functional states, wherein the filling state of the balloon component in the measuring mode assumes a value of constant, defined volume during the measurement, said value corresponding to a flaccid filling state, and the filling state of the balloon in the oesophageally or tracheally sealing functional mode maintains a constant, sealing pressure specified by the user. The controller device connected to the tube unit or catheter unit ensures rapid displacement of filling medium into and out of the tube balloon or catheter balloon in the state of tracheal or oesophageal sealing, wherein the tracheally or oesophageally sealing target pressure is maintained continuously by compensating pressure fluctuations in the balloon caused by respiratory mechanics by a continuous, compensating displacement of filling volume. The user can switch between the two functional states by means of a manual switchover function or by means of a programmable, chronological cycle. In addition to the possibility of an intermittent monitoring of the respiratory mechanics and a continuous, tracheally or oesophageally sealing balloon tamponade, the balloon placed in the trachea or oesophagus allows, in both functional states, the thoracic derivation of a triggering, respiratory-mechanical signal which can trigger a ventilating stroke assisting the patient in a ventilator connected to the device. The invention also describes structural and functional options for the simultaneous derivation of a neural and/or muscular electrical signal from the diaphragm of the patient and a respiratory-mechanical signal on the basis of thoracic or pleural pressure fluctuations derived tracheally or oesophageally.

Processing status information of a medical device

A system (100) is provided for processing status information of a medical device (020-023). The medical device performs a medical function at a bedside of a patient and is arranged for generating an alarm signal (030) to alert a caregiver of the patient to an occurrence of an event which is associated with the performing of the medical function. A status interface (120) acquires a device signal (024) of the medical device, the device signal comprising status information which is indicative of a current status of the performing of the medical function. Moreover, an analysis subsystem (140) analyzes the status information to estimate an imminent occurrence of the event based on said current status, and a notification subsystem notifies the caregiver of the imminent occurrence away from the bedside of the patient of the event by a generating a notification signal (162) for a notification device (060-064). The priority of notifying the caregiver is based on an estimate of whether the patient is asleep. The system enables the caregiver to be notified about the event ahead of time, i.e., before the event occurs and thus before the medical device generates an alarm signal. Advantageously, the patient is less disturbed by alarm signals during sleep.

ALERT MANAGEMENT FOR PHYSIOLOGICAL EVENT DETECTION

Systems, devices, and methods for managing alerts associated with a target physiological event such as a worsening heart failure event are described. A system may detect one or more alert onsets using an onset threshold, and one or more corresponding alert terminations using a reset threshold. Alerts may be issued corresponding to the detected alert onsets and alert terminations. The system may compare the alerts to a specified alert characteristic, and iteratively adjust the onset or reset threshold until the alerts corresponding to the adjusted onset or reset threshold satisfy the specified alert characteristic. The adjusted onset and reset thresholds may be presented to a user or a process for detecting the target physiological event.

System and method of determining a risk score for triage

The present disclosure provides a system and method of determining a risk score for triage. In particular, a system is provided for providing an assessment of risk of a cardiac event for a patient, for example an incoming patient to a hospital emergency department complaining of chest pain. In the disclosure, the system includes an input device for measuring physiological data based vital signs parameter of the patient, a twelve-lead electrocardiogram (ECG) device for establishing an ECG obtained from results of the electrocardiography procedure, and determining an ECG parameter and a heart rate variability (HRV) parameter therefrom. An ensemble-based scoring system is further provided, establishing weighted classifier based on past patient data and where the vital signs parameter, the ECG parameter and the HRV parameter are compared to corresponding weighted classifiers to determine a risk score. A corresponding method to determine a risk score for triage is also provided.

MODULAR WRIST-WORN PROCESSOR FOR PATIENT MONITORING

The invention provides a physiological probe that comfortably attaches to the base of the patient's thumb, thereby freeing up their fingers for conventional activities in a hospital, such as reading and eating. The probe, which comprises a separate cradle module and sensor module, secures to the thumb and measures time-dependent signals corresponding to LEDs operating near 660 and 905 nm. The cradle module, which contains elements subject to wear, is preferably provided as a disposable unit.

Bed apparatus and patient detection method

A bed apparatus includes: a mattress mounted on a bed body; and, first cells arranged on both left and right sides in a longitudinal direction of the bed body and is configured to change the body position of a patient on the mattress by inflating the first cells alternately. When the first cells on the left and right sides are inflated, and when a difference in pressure between the first cells on the left and right sides has continuously fallen within a decision pressure value range for a decision pressure value continuation time, the body position of the patient is changed, whereas when the difference has not continuously fallen within the pressure value range for the continuation time or when the difference has continuously fallen out of the pressure value range for the continuation time, change of the body position of the patient will not be performed.

A method for collecting and analyzing urine at the time it is released uses a urine collecting tube joined with a canister. Suction is produced in the collecting tube to join the tube with a penis or to the exterior surface of a female urethra orifice. Once suction is achieved the collecting tube stays in place by suction action. When urine flows into the urine collecting tube a sensor triggers a vacuum pump to produce a higher level of suction to flush the urine into the canister where a level sensor determines the quantity of urine received. Various sensors in the canister determine levels of non-urine partials such as occult blood, drugs, salt, and other substances. When urine is no longer detected within the urine tube, the vacuum pump is turned off and a low-level vacuum remains to assure interconnection with the urine tube.
