Methods and systems for controlling and monitoring pressurization data. The methods and systems advance beyond the prior art in their ability to convey pressurization data unambiguously. The methods and systems include a novel combination of visual cues and control features to insure that pressurization data may be analyzed accurately. For example, the visual cues and control features include changing the background color of the display area and providing a pressurization arrow to indicate pressurization or depressurization; a time showing the elapsed time of pressurization or depressurization; a pressurization number indicating the number of pressurization cycles that have occurred; software keys for making configuration choices; and text and graphic display modes. A touch interface may be provide for user interaction. To insure accurate pressure measurements, at least one pressure reference standard may also be utilized.

An electronically controlled syringe system for connection to a balloon catheter or other balloon-type member and for monitoring, displaying and optionally recording inflation or deflation data when the syringe system is used to inflate or deflate the balloon of the catheter or other balloon-type member. A syringe having a barrel and a syringe plunger is selectively operable to increase fluid pressure applied to the balloon catheter or other balloon member by sliding the plunger further into the barrel. Positive pressure applied to the balloon catheter or member is released by withdrawing the syringe plunger toward the rear of the barrel. A piezoresistive semiconductor transducer placed in fluid communication with the fluid pressure applied by the syringe, senses the fluid pressure and outputs an electrical signal representative of that pressure. The electric signal is input to a controller where the signal is digitally processed so as to derive and record therefrom electronic data representing the magnitude of applied fluid pressure, and so as also to derive the length of time that fluid pressure is applied. The electronic data representing this information is displayed and optionally recorded.

A self-contained battery operated disposable blood pressure monitor having a semi-conductor transducer therein, the front side of which is intended to be fluid communication with an incompressible fluid in a intracorporeal catheter inserted in the heart of a patient for direct blood pressure monitoring. A calibration port vents the backside of the transducer to calibration and atmospheric pressures. The monitor contains circuitry electrically connected to the transducer which receives electrical signals output by the semi-conductor chip in response to the pressures exerted upon it through the pressure monitoring port. The circuity then electronically processes the signals so as to derive electronic data representing the mean arterial pressure pulse rate, and both systolic and diastolic blood pressures. The circuitry also analyzes the pressure wave forms of the pressure signals detected for poor signals so that it can present a visual diagnostic representative of the problematic pressure condition.

A syringe having a barrel and a syringe plunger is selectively operable to increase fluid pressure applied to the balloon catheter or other balloon member by sliding the plunger further into the barrel.

A piezoresistive semiconductor transducer placed in fluid communication with the fluid pressure applied by the syringe, senses the fluid pressure and outputs an electrical signal representative of that pressure. The electrical signal is received by a RF transmission module that is permanently mounted to the syringe barrel. The RF transmission module derives transmission data from the electrical pressure signal and wirelessly transmits the transmission data via a radio frequency signal to a remote console.

An electronically controlled syringe system for connection to a balloon catheter for automatically monitoring, displaying and recording inflation or deflation data. A syringe having a barrel and a plunger is used to apply or to release pressure to the balloon catheter or other balloon member. A transducer housed on the barrel of the syringe senses fluid pressures applied by the syringe. An electromagnetic signal output by the transducer means is input to a controller where the signal is digitally processed so as to derive and record therefrom electronic data representing the magnitude of applied fluid pressure and the length of time that positive fluid pressure is applied, which derived data is automatically displayed and recorded. The deflation of the balloon-type member is similarly processed and recorded. The controller is also programmable to permit input of various control parameters, such as a lesion location identifier, a maximum positive inflation pressure and maximum duration for applying pressure.

An electronically controlled syringe system for connection to a balloon catheter for automatically monitoring, displaying and recording inflation or deflation data. A syringe applies and releases pressure to and from the balloon catheter. A transducer housed on the syringe barrel emits at atmospheric pressure a signal by which both the syringe and transducer are recognizable to the system as a particular type of syringe. The system prompts the user to verify the recognized type of syringe. The system prompts the user to verify the recognized type of syringe. The transducer, which can be calibrated, senses fluid pressures applied by the syringe. The signal output by the transducer is input to a controller where the signal is digitally processed so as to derive and record therefrom data representing the magnitude of applied fluid pressure and the length of time that pressure is applied by the syringe. The data is automatically displayed and recorded. The syringe system permits input of various control parameters, such as a maximum positive inflation pressure and maximum duration for applying pressure.

128675

A novel pressure transducer apparatus for medical pressure monitoring apparatus having a housing with a calibration port. The patient side of the transducer senses fluid pressures to be monitored. The non-patient side of the transducer is hermetically sealed in the housing of the apparatus. The housing has a female calibration port communicating, via a pinhole, with the non-patient side of the transducer. The non-patient side of the transducer can thus alternatively be vented to atmospheric pressure or be exposed to a vacuum calibration pressure.

This invention relates to a measuring device, which includes a body. A digital display is located in the body, the digital display being configured to show at least a linear measurement. The measuring device also includes a holding portion coupled to the body and configured to slidably engage an elongate member, such as a catheter or introducer sheath, in a space provided between the holding portion and the body. The measuring device also includes a sensor or transducer located in the body and configured to measure at least a linear distance traveled by the elongate member, such that the linear measurement is associated with the linear distance.

The present invention relates to systems and methods for measuring the amount of fluid. A fluid source is in fluid communication with a measuring system. The fluid source includes a non-collapsible walled container for dispensing or introducing fluid. The measuring system includes a sensor in fluid communication with the container that senses the volume of the gas, and a system that calculates the amount of fluid flowing through an opening of the container based on the amount of gas flowing through an opening of the container. The volume of gas entering or exiting the container is measured rather than directly measuring the amount of fluid leaving or entering the container to determine in a more accurate, less complicated and less expensive manner the volume of fluid.
