Cardiac output detector wireless transmission device

Abstract

The invention discloses a cardiac output detector wireless transmission device which is mainly applied to detecting transient temperature of human arterial blood. According to the technical scheme that a physical layer and a data link layer of a CAN (controller area network) protocol are integrated in a CAN bus communication interface, the cardiac output detector wireless transmission device is a main unit capable of receiving and controlling wireless transmission of multiple auxiliary units. The cardiac output detector wireless transmission device is structurally characterized by being composed of an infusion connector, a button cell, a wireless communication module, a wireless communication module shell, a temperature sensor, a PICCO (pulse induced contour crdic output) double-cavity tube, a catheter fixator, and a wireless receiving module and a software program of a cardiac output detector; the cardiac output detector also named as a PICCO catheter before innovation is a measuring instrument used at the front end of the cardiac output monitor; the measuring principle of the cardiac output monitor is that single cardiac output (CO) is measured by adopting a hot dilution method, and continuous cardiac output (ICCO) is acquired by analyzing area under arterial pressure-waveform curves; meanwhile, intrathoracic blood volume (ITBV) and extravascular lung water (EVLW) can be calculated.

Description

Technical field: [0001] The invention relates to a wireless transmission device for a cardiac output detector. It is mainly used to detect the instantaneous temperature in human arterial blood. That is, the detection signals sent by a plurality of cardiac output detectors are sent to a receiving device of a cardiac output detector. Background technique: [0002] The inventive technology involved in the present invention: the technology of converting the temperature analog signal of the cardiac output detector into a digital signal is invented. [0003] The technology involved in the application: the CAN bus host receives multi-extension function, and innovatively applies the technology that the cardiac output detector multi-extension wirelessly sends to the host (cardiac output detector) to receive signals. [0004] The PICCO catheter of the traditional cardiac output detector is connected to the host through a special connector and a special cable, and after measuring the...

AI Technical Summary

Problems solved by technology

When the patient needs to move, the PICCO and the detector must be moved together, and at the same time, it is very inconvenient to be limited by the power cord

Moreover, a detector can only measure one patient in real time, and the anti-interference ability is relatively weak, requiring expensive shielded coaxial cables, and the transmission of analog signals is the biggest problem of data uncertainty
