20220054007 · 2022-02-24 · ·

Intraocular pressure sensing devices and methods of use. The intraocular pressure sensing devices may include one or more calibration sensors that are adapted to sense fibrotic growth over the implant post-implantation. Methods can take into account the amount of fibrosis over the implant, and its effect on IOP, when calculating the subject's IOP. Additionally, methods herein can calculate IOP while factoring in blink-induced variation in IOP.

20170299456 · 2017-10-19 ·

The present invention makes it possible to, even when a stainless steel is adopted in a diaphragm: prevent the diaphragm and a strain sensor from exfoliating from each other; be hardly susceptible to the influence of temperature in an operating environment; not allow the sensitivity of a pressure sensor to be dominated only by the mechanical characteristic of a material constituting the diaphragm; and increase the degree of freedom in design of members constituting the pressure sensor. A pressure sensor according to the present invention is, in order to solve the above problems, characterized in that: the pressure sensor has a diaphragm deforming by the pressure of a fluid, an elastic body covering the whole surface of the diaphragm and joining to the diaphragm on one side, and a strain sensor being arranged by joining on the other side of the elastic body and on an end side apart from a position corresponding to the center of the diaphragm and detecting the deformation of the elastic body working together with the deformation of the diaphragm as a strain; and the elastic body is formed of a material having a linear expansion coefficient close to the linear expansion coefficient of a material constituting the strain sensor.

A system for automated adjustment of a pressure set by a ventilation device, in particular a positive and-expiratory pressure and/or a maximum airway pressure, the system comprising a pressure detection arrangement for detecting a transpulmonary pressure at the end of an expiration phase and/or for detecting a transpulmonary pressure at the end of an inspiration phase, and a device for automated adjustment of the pressure set by the ventilation device on the basis of the transpulmonary pressure detected at the end of the expiration phase and/or the transpulmonary pressure detected at the end of the inspiration phase.

Biodegradable pressure sensor
11666239 · 2023-06-06 · ·

A biodegradable pressure sensor for measuring vital physiological pressures and for preventing the buildup of dangerous internal forces in impaired organs. The pressure sensor is constructed by depositing Mg or Mo on both sides of a PLLA film. This layered configuration (Mg/PLLA/Mg) or (Mo/PLLA/Mo) may then be encapsulated by layers of high molecular weight PLA. These materials are biodegradable such that after implantation, the sensor does not require invasive removal surgery that can damage directly interfaced tissues.

Provided is a pressure gauge capable of being effectively used for internal pressure measurement of a balloon catheter and capable of providing easy monitoring of a pressure value even when measuring internal pressure of an extracorporeal circulation circuit. The pressure gauge measures internal pressure of a balloon catheter used for treatment and diagnosis or pressure of a body lumen of a living body and includes a coil-shaped tube 2 to elastically deform. One end of the tube 2 is set as an open fixed end and the other end is set as a sealed free end and pressure introduced from the open fixed end can be measured based on a displacement position of the tube 2 due to the pressure.
