An airbag (10), a blood pressure measurement apparatus, and a blood pressure measurement method are provided. The blood pressure measurement apparatus includes a cavity (20), a pressing part (30), an air pump (40), a barometric pressure sensor (50), and an airbag (10). The airbag (10) is long-strip-shaped, the airbag (10) has a fixed end (113) and a free end (115), the fixed end (113) is fixed in the cavity (20), a plurality of grooves (101) are distributed on a surface of the airbag (10) along a length extension direction, and the grooves (101) extend along a width direction of the airbag (10). Each groove (101) can divide the airbag (10) into a pressurized area (110) and a non-pressurized area (115) along the length direction when the pressing part (30) movably disposed in the cavity (20) is pressed against the groove (101). The pressurized area (110) and the non-pressurized area (115) isolate air flow from each other, air holes (102) connecting the inside and the outside of the airbag (10) are distributed between every two adjacent grooves (101), and the cavity (20) is configured to accommodate the non-pressurized area (115) of the airbag (10), and when the airbag (10) does not work, accommodate the entire airbag (10). The blood pressure measurement apparatus in this application can adjust ratios of the pressurized area to wrist circumferences of different people. This improves blood pressure signal collection stability and blood pressure measurement accuracy.

A sensing system for sensing a potential complication at a venous catheter site. The system includes a sensor module for attachment at the site of the catheter. The sensor module includes a pressure sensor configured to generate pressure data representing measured pressure at the site of the catheter; a temperature sensor configured to generate temperature data representing measured temperature at the site of the catheter; and two pairs of bio impedance electrodes that generate bioelectrical signals representing bioelectrical activity at the site of venous catheter and a transmitter for transmitting the pressure, temperature data and bio impedance data. The system also includes a computing device configured to receive the response signal that includes the generated pressure, temperature and bio impedance data; and transmit the pressure temperature and bio impedance data to a user device for comparing the generated pressure temperature bio impedance data to threshold values indicative of intravenous complications.

An example operation includes one or more of collecting, by the transport, data from a device associated with an occupant containing an amount of movement of the device and an amount of time elapsed during the movement, and determining an injury level of the occupant based on the data after a collision.

Systems and methods for the treatment of gastroesophageal reflux disease (GERD) include at least one electrically stimulating electrode coupled to a pulse generator. Individuals with GERD are treated by implanting a stimulation device within and/or proximate the patient's lower esophageal sphincter, gastric fundus, or other nearby gastrointestinal structures and applying electrical stimulation to the patient's lower esophageal sphincter and/or fundus, in accordance with certain predefined protocols. Electrical stimulation provided by the disclosed systems results in an increase in the length of the high pressure zone of the LES and/or modulation of the receptive relaxation response of the fundus to decrease gastric pressure, creating a longer barrier to the reflux of gastric contents or increasing functional lower esophageal pressure respectively, thereby treating GERD.

A vaporization device includes a first portion and a second portion. The first portion includes a first body defining a first interior volume, a first half of a split-pod, a second half of a split-pod, an opening, a first heating apparatus, and a second heating apparatus. The first half of the split-pod is configured to hold a nicotine-containing liquid. The second half of the split-pod is configured to hold a non-nicotine-containing liquid. The opening separates the first half from the second half of the split-pod. The first heating apparatus is dedicated to the first half. The second heating apparatus is dedicated to the second half. The second portion includes a second body defining a second interior volume and a computing system. The computing system is disposed within the second interior volume. The computing system is configured to vary an amount of current supplied to the first and second heating apparatuses.

A control apparatus detects a misalignment between an irradiation position of a transdermal treatment device and a target irradiation position. When the misalignment is detected, the control unit stops irradiation of the transdermal treatment device or moves the irradiation position closer to the target irradiation position.

The present invention discloses a capsule device for pressure measurement. The capsule device comprises a capsule enclosure, a data transmission assembly and a thin film pressure sensor. The capsule enclosure is formed with an accommodating chamber, and the data transmission assembly is arranged in the accommodating chamber. The thin film pressure sensor is attached to the outer surface of the capsule enclosure to measure pressure, and the thin film pressure sensor is connected with the data transmission assembly.

A method for estimating blood pressure using a blood flow occlusion system applied to an artery includes receiving from a first sensor a sensed signal; processing at a processor the sensed signal to detect beats in a pulsatile signal; determining validity of the detected beats; storing the detected beats and data associated with the detected beats in the sensed signal as the pressure applied to the artery by the blood flow occlusion system deflates towards a level below a nominal level; determining baseline beat characteristics; evaluating the stored beats and associated data to detect change in beat characteristics as compared to the baseline beat characteristics; selecting a beat before the detected change in the beat characteristic as the last beat indicating the onset of the diastolic blood pressure for the artery; determining a value of the applied pressure at the last beat as the diastolic blood pressure for the artery.

Embodiments of the invention provide devices and systems to monitor fullness of a patient's bladder. One embodiment of a bladder fullness (BF) measure system comprises a sensor device (SD) and a controller. The SD generates an output signal (OS) based on the force exerted by the bladder against SD the wherein the OS corresponds to a degree of BF. The SD may be attached to the bladder wall or adjoining tissue and positioned between the bladder and the pubic bone such that the SD is not affected by tissues force other than that from the bladder. The controller connects to the SD and causes an associated implant to perform a function when the SD output signal exceeds a predetermined threshold. Embodiments are particularly useful for providing information on BF to patients suffering from spinal injury or other conditions whereby they have lost the ability to sense BF and/or voluntarily urinate.

A pressure sensing device including an elongate housing configured to be at least partially inserted into a user, and that defines an external surface having a proximal end and a distal end defining a longitudinal axis therebetween. The device includes a first pressure sensor, configured to sense pressure applied to a first portion of the external surface and to convert the sensed pressure to first pressure data, and a second pressure sensor, configured to sense pressure applied to a second portion of the external surface and to convert the sensed pressure to second pressure data. Sensor is spaced, along the longitudinal axis, toward the distal end from sensor.
