Problems solved by technology

[0003] At present, the relevant design and research on the measurement of coronary blood flow reserve at home and abroad are mainly concentrated in the field of cardiology intervention. It obtains the specific value of coronary blood flow reserve by measuring the pressure ratio of the distal and proximal segments of target vessel stenosis, but This system is specially designed for medical interventional systems. It sends the pressure probe to the target blood vessel through the radial artery or femoral artery for pressure measurement. It cannot be used in coronary artery bypass surgery. Therefore, it is subject to the lack of relevant measurement equipment. Limitations prevent application of the valuable guiding theory of fractional coronary flow reserve in coronary artery bypass surgery

Embodiment Construction

[0020] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, but not as a limitation of the present invention.

[0021] In the present invention, in the case of no contrary description, the used orientation words such as "up, down, left and right" usually refer to the up, down, left and right shown in the accompanying drawings; "inside and outside" Refers to the inside and outside of the outline of each part itself.

[0022] A preferred embodiment is given below:

[0023] as attached figure 1 As shown, the coronary artery blood flow reserve fraction measurement system of the present invention is mainly composed of an arterial puncture needle 1 , a pen handle 2 , a medical tee 4 , a pressure sensor 5 , and a calculation and display 6 . The arterial puncture needle 1 is fixed at one end of the pen handle 2 and connected to the first interface 41 of the medical tee 4 through the conduit 3 passing through th...

Abstract

The invention discloses a coronaryartery blood flow reserve fraction measuring system, and belongs to the field of medical instruments. Thecoronaryartery blood flow reserve fraction measuring systemstructurally comprises an arterial puncture needle, a pressure sensor, a calculation and display device, the rear end of the arterial puncture needle and the pressure sensor are connected through a catheter, the pressure sensor iselectrically connected with the calculation and display device, and the calculation and displaydevice is used for calculating and displaying coronary arteryblood flow reserve fraction FFR. Compared with the prior art, thecoronaryartery blood flow reserve fraction measuring system can accurately measure the specific numerical value of thecoronaryartery blood flow reserve fraction in a bypass surgery, and the selection of a target blood vessel during the operation is more accurately guided, bridge blood vessels are built reasonable, accurately and safely,and a good promotion and application value is achieved.

Description

technical field [0001] The invention relates to the field of medical equipment, and specifically provides a coronary artery blood flow reserve fraction measurement system, which is especially suitable for the field of coronary heart disease surgical treatment. Background technique [0002] Coronary artery bypass grafting is the main method for the treatment of coronary heart disease. At present, the main basis for selecting target vessels in coronary artery bypass grafting is still coronary angiography. Pure coronary angiography can no longer satisfy the judgment of the functional significance of coronary artery lesions. Coronary blood flow reserve fraction can more accurately guide the selection of target vessels in coronary artery bypass surgery, and has incomparable advantages for the reasonable treatment of coronary heart disease. [0003] At present, the relevant design and research on the measurement of coronary blood flow reserve at home and abroad are mainly concentr...
