Tubes (e.g., catheters, endotracheal or chest tubes and bypass grafts) are provided, comprising a catheter and a plurality of sensors.

A surgical system is disclosed including a housing assembly including an elongate shaft extending therefrom and a loading unit including a lug extending therefrom. The elongate shaft includes a spring assembly. The loading unit is rotatable relative to the elongate shaft between an unlocked position and a locked position. The spring assembly is configured to resist rotation of the lug as the loading unit is rotated toward the locked position.

An exemplary system includes a memory storing instructions and a processor communicatively coupled to the memory. The processor is configured to execute the instructions to receive, from a sensor of a surgical instrument, environmental condition information associated with the surgical instrument and detected by the sensor while the surgical instrument is disconnected from an external power source, the surgical instrument including circuitry configured to be powered and operate only while the surgical instrument is connected to the external power source, determine, based on the environmental condition information, an operational condition of the surgical instrument, and provide a notification indicating the determined operational condition of the surgical instrument.

The present disclosure relates to a method for calibrating a blood glucose value in a continuous blood glucose measurement system. More particularly, blood glucose values can be accurately calibrated according to a calibration mode by differently selecting calibration modes for calibrating blood glucose values on the basis of whether the difference between a blood glucose value measured by a continuous blood glucose measurement system and a reference blood glucose value measured by a separate blood glucose meter is outside a set range. In addition, the blood glucose value of a user can be accurately calibrated by activating, to be scrolled on an input window, only the ranges of the blood glucose value and a reference blood glucose value calculated on the basis of a preset critical range, or by forcibly or automatically calibrating the blood glucose value by a second calibration mode which uses multiple reference blood glucose values, when a reference blood glucose value outside the reference blood glucose value range is input.

The disclosure relates to a method for operating a medical device, (e.g., an imaging apparatus such as an X-ray device or magnetic resonance tomography unit), and a fault monitoring apparatus for carrying out the method. The fault monitoring apparatus is connected to the medical device via a signal connection. In the method, the fault monitoring apparatus receives an item of status information from the medical device and stores the item of status information in a system state. Further, the fault monitoring apparatus compares the stored system state with a predetermined target state, and, depending on the comparison, releases a function of the medical device, wherein the predetermined target state has a successfully executed function test.

A monitoring device configured to be attached to a subject includes a photoplethysmography (PPG) sensor configured to measure physiological information from the subject, and at least one processor configured to process signals from the PPG sensor to determine heart rate and RR-interval (RRi) for the subject, and to determine a heart rate pattern for the subject over a period of time. The at least one processor is configured to change a sampling frequency of the PPG sensor for determining RRi in response to the determined heart rate pattern. The at least one processor is configured to reduce the sampling frequency of the PPG sensor in response to determining a pattern of heart rate below a threshold.

A wearable device that attaches to a body part of a user via an attachment member operates in at least a connected and a disconnected state. One or more sensors located in the wearable device and/or the attachment member detect the user's body part when present. Such detection may only be performed when the attachment member is in a connected configuration and may be used to switch the wearable device between the connected and disconnected states. In this way, the wearable device operates in the connected state when worn by a user and in the disconnected state when not worn by the user.

A clamping device for reducing blood flow in a human limb comprises a first rigid part having a first inner profile, and a second rigid part having a second inner profile generally facing the first inner profile. A coupling portion couples the first rigid part and second rigid part to each other. The first inner profile extends further away from the coupling portion than the second inner profile. The first and second inner profiles define a recess, the recess being shaped to enable the clamping device to be positioned on the human limb, and the clamping device being configured to shift between an expanded configuration and a clamped configuration. The first and second inner profiles are arranged to apply pressure against the human limb when the device is in the clamped configuration and thereby to apply pressure to blood vessels in the human limb and reduce blood flow through the blood vessels.

A process coordinates the acoustic alarm signals output by different medical devices (1). A first medical device (1a) outputs, at a time interval before an output of a n acoustic alarm signal, a pre-signal which differs from the acoustic alarm signal with respect to at least one property. A further device receives the pre-signal output by the first medical device (1a) and carries out an analysis of the received pre-signal. As a function of a result of the analysis of the pre-signal, an alarm signal output unit (4) of a second medical device (1b) is driven in such a way that, as a function of the result of the analysis, at least one property of an alarm signal which is currently being output or will be output by the alarm signal output unit (4) is at least temporarily changed and/or a pre-signal is transmitted by the second medical device (1b).

A vascular hemostasis system includes a first compression member and a second compression member separated from the first compression member to create a body part receiving space that is adapted to receive a body part having a vascular opening in need of hemostasis. A compression mechanism connects the first compression member to the second compression member, and the compression mechanism is configured to selectively move the first compression member towards or away from the second compression member to adjust the size of the space and thereby provide varying amounts of compression to the body part. An optional control system includes a detecting system, such as a pulse sensor, and a controller. The controller may be adapted to control the compression mechanism in response to the detecting system. In one version, the compression mechanism includes a locking mechanism that can selectively prevent the first compression member from moving away from the second compression member. The vascular hemostasis system may be used in process to provide hemostasis.
