A suction cup electrode and methods thereof configured to be used with an electrocardiogram (EKG or ECG). The suction cup electrode is reusable and creates an effective comfortable suction to most skin surfaces of most patients and is able to be applied to and removed from patients with minimal force and discomfort for patients.

A pulse oximetry device is provided that fixates generally around a user's wrist. The device may include one or more mechanical features that fix the device at, for example, a distal end of a wearer's ulna bone. The device may include one or more projections formed from a suitable material (e.g., elastomer such as silicon) that cause the device to fit snugly against the wearer's wrist and remain in place even when the wearer is moving, thus reducing motion artifacts in signals detected by the device. The device may include one or more mechanical features or fins that reduce ambient or stray light in the measurement area. The device may include one or more detectors, and one or more light sources, each having a different axis resulting from the manner in which each is angled toward a virtual center point of the distal end of a wearer's ulna bone.

An ECG device comprising limb leads and chest wall leads is described which is also suitable for deriving the hemodynamic activity of the heart and the function of the vessels and, respectively, also for evaluating the fluid equilibrium. This is achieved in that at least part of the electrodes of the multichannel ECG is developed with additional embodiments for physical emissions and measurements, for example, electric current and voltage, pressure, sound vibrations, light, and that an electrode is provided for the current supply and, respectively, the voltage measurement at the upper thorax aperture. Furthermore, an alternating current field is built up between the electrodes or, respectively, the distance between the electrodes is used as an ion conductor. Thus, during the conventional ECG writing, the acceleration of the blood and hence the cardiac output, the valve closure and the valve opening, as well as the mechanics of individual circulation sections, for example, also the pulse wave transit time, the blood flow in body sections, the body composition etc. can also be registered and output simultaneously with the routine ECG.

In one example aspect, a system is disclosed that includes an image capture device; a capillaroscope attachable to the image capture device, the capillaroscope including: a light source configured to provide offset light at an angle and location offset from a center horizontal axis and produce oblique remitted light off a patient site; a reverse lens through which the oblique remitted light passes therethrough; and one or more telescopic lenses through which the remitted light passes therethrough to a lens of the image capture device after passing through the reverse lens.

The present invention provides materials and methods for forming an interface between an appliance and living tissue using a foamed elastomeric material which contacts the tissue or similar surfaces. The elastomeric material is in the form of a durable and washable material that when applied to living tissue or similar surfaces displaces and flows in to non-conforming areas creating an air and/or water tight seal that substantially returns to an original shape when removed from the contact surface. The appliance may also include structural elements designed to optimize comfort, compliance and seal achieved through minimizing the pressure variation along the contact surface of the therapy device.

A sensor for measuring a vital parameter in the auditory canal comprising a sensor element (1) and a positioning element (3), both connected to a sensor element attachment (2). The positioning element (3) has a shape that reproduces the inside of the ear and positions the sensor element (1) and sensor element attachment (2) at least partially in the auditory canal (8) in a stable manner. The position of the sensor element (1) in the auditory canal (8) is determined by the depth of penetration of the sensor element attachment (2) in the auditory canal (8). The sensor element (1), the sensor element attachment (2), and the positioning element (3) are arranged at least partially in a housing (4) adapted to the anatomy of the person's head.

The present invention relates to a sampling unit, a measurement system and method for transcutaneous blood gas measurements. In particular the invention relates to a sampling unit and system adapted for rapid measuring and monitoring of blood gases in a continuous gas flow. The sampling unit is provided with an ambient air inlet and a blood gas extraction and mixing chamber wherein air is mixed with extracted blood gases. The method of continuous transcutaneous measurement of carbon dioxide in the blood utilizes a pulsed heating to minimize the detrimental effects of the heating.

Electrode array for monitoring of physiological parameters and devices including or utilizing same, the electrode array including an active electrode configured to provide an electrical signal and at least two inactive electrodes configured to collect the electrical signal transferred from the active electrode, wherein each of the at least two inactive electrodes are positioned at a different predetermined distance from the active electrode.

A bio-optical physio-logging device designed for attaching to an animal and capturing real-time physiological data of the animal. The bio-optical physio-logging device includes a hardware architecture platform configured to capture physiological signals including the movement, position, and temperature of an animal. The bio-optical physio-logging device is further operable to generate real-time alerts and recommendations based on the animal physiological data.

An ultrasound endoscope includes: an ultrasound probe arranged in a distal end rigid portion; a suction and forceps port provided in a vicinity of the ultrasound probe; a treatment instrument insertion channel and a negative pressure channel communicating with the suction and forceps port; and a control valve configured to variably regulate a negative pressure for suction that is transmitted to the suction and forceps port through the treatment instrument insertion channel and the negative pressure channel to two or more states.
