Embodiment Construction

[0027] 1 illustrates a preferred embodiment of a wireless pressure system 100 according to the present invention, which can communicate data between a standard pressure sensor 106 (eg, complying with the aforementioned BP22 standard) and a standard vital sign monitor 108 (eg, complying with the aforementioned BP22 standard). . More specifically, wireless pressure system 100 includes portable unit 102 that provides an excitation voltage to sensor 106 to receive an output voltage proportional to the pressure of catheter 110 . The portable unit 102 digitizes the pressure data and then transmits the data to the monitor interface unit 104 , which emulates a corresponding output voltage to the vital signs monitor 108 . As a result, the vital signs monitor 108 receives and displays a signal from the monitor interface unit 104 that corresponds to the actual pressure measured by the portable unit 102, allowing the user to interface with and thus utilize various sensors 106 and to compl...

Abstract

In one embodiment, the present invention provides a wireless communication system for use with a blood pressure monitor system. The wireless communication system includes a portable unit that connects to a typical pressure transducer and a monitor interface unit that connects to a typical vital signs monitor. The portable unit obtains a pressure reading from the transducer by providing an excitation voltage to the transducer, then wirelessly transmitting the pressure data to the monitor interface unit. The monitor interface unit measures the excitation voltage supplied by the vital signs monitor to supply the pressure reading in a format recognizable by the vital signs monitor.

Description

technical field Background technique [0001] Blood pressure measurement is an important technique used by medical personnel to diagnose and treat a wide range of injuries and health conditions. By measuring and specifically monitoring a patient's blood pressure, medical staff can be alerted to problems at an early stage, increasing the likelihood of successful treatment. [0002] While indirect methods of blood pressure monitoring, such as the use of blood pressure cuffs and stethoscopes, usually require quick pressure readings, these methods may be inaccurate by up to 10%, making these methods unsuitable for longer-term blood pressure monitoring in more critical patients. Therefore, direct blood pressure monitoring methods are preferred for patients with serious or critical conditions due to their increased accuracy and easier long-term implementation. [0003] The most popular method of direct blood pressure monitoring is performed by catheterization, in which an irrigatio...
