Technical Field

[0001] The utility model relates to the technical field of medical equipment, and more specifically, to a novel non-invasive cardiac output and pressure monitoring device. Background Art

[0002] Non-invasive cardiac output, also known as impedance cardiography, abbreviated as ICG, is a non-invasive measurement method that obtains hemodynamic data by measuring blood flow instead of measuring blood pressure. Its principle is to calculate cardiac output and other hemodynamic values ​​based on the changes in thoracic impedance generated when the heart ejects blood through TEB technology (thoracic bioimpedance technology).

[0003] Existing non-invasive cardiac output detection often needs to be connected to the host via wires. The wires need to be laid flat during use, which can easily cause the wires to get tangled and trip the doctor, resulting in poor contact of the wires, affecting the service life of the wires and the accuracy of the monitoring data.

[0023] The fixing brace 3 includes a support plate 301 and an elastic band 302. Two elastic bands 302 are connected to one side of the support plate 301. The support plate 301 is in an I-shape and both sides extend upward in an arc shape to better fit the patient's hand. One end of the elastic band 302 is adhered to the other side of the support plate 301 through Velcro, and the support plate 301 is conveniently fixed to the patient's hand through the elastic band 302 and the Velcro.

[0024] The positioning patch 4 includes a positioning plate 401, a limit block 402 and a transparent film 403. Two limit blocks 402 are installed on the top of the positioning plate 401. A viewing hole is opened at the center of the top of the positioning plate 401. A transparent film 403 is attached to the inside of the viewing hole. There are two parallel lines on the transparent film 403. When in use, first draw a line on the patient's hand, and then stick the positioning plate 401 on the patient's hand so that the line of the patient's hand is located between the two lines of the transparent film 403, which plays a role in limiting the position of the positioning patch 4.

[0025] A groove is provided at the bottom of the top plate 101, and a sensor 106 is elastically connected to the inside of the groove through a buffer spring 105. A rubber gasket 107 is connected to the bottom of the groove. A limiting groove is provided at the bottom of the rubber gasket 107 and is slidably connected to the limiting block 402. The rubber gasket 107 is in contact with the transparent film 403. The rubber gasket 107 is limited at the top of the positioning patch 4 by the limiting groove and the limiting block 402, so that the sensor 106 is located directly above the patient's hand line, which is convenient for subsequent monitoring.

[0026] The clamping assembly includes a limit spring 108, and a positioning block 109 is elastically connected to the top of the top plate 101 through the limit spring 108. A placement groove slidably connected to the wireless data transmission terminal 104 is provided on the top of the top plate 101, and the placement groove is connected to the inside of the top plate 101. The top of the positioning block 109 is provided with an inclined surface that slidably contacts the wireless data transmission terminal 104. The inclined surface reduces the friction resistance between the positioning block 109 and the wireless data transmission terminal 104, so that the positioning block 109 slides to both sides when the wireless data transmission terminal 104 is pressed. Positioning grooves slidably connected to the positioning block 109 are provided on both sides of the wireless data transmission terminal 104. When the positioning block 109 is stuck in the positioning groove of the wireless data transmission terminal 104, the wireless data transmission terminal 104 is fixed. A transmission rod 110 is rotatably installed at the middle end of the top plate 101. The transmission rod 110 is symmetrically arranged in an eight-shaped shape compared to the wireless data transmission terminal 104. A pressing block 111 is slidably installed at the bottom of the top plate 101, a guide block 1091 is installed on the outer side of the positioning block 109, and a guide block 2 1111 is installed on the outer side of the pressing block 111. The top and bottom of the transmission rod 110 are provided with guide holes slidably connected to the guide block 1091 and the guide block 2 1111. The guide holes realize the linear sliding of the guide block 1091 and the guide block 2 1111 close to each other when the transmission rod 110 rotates. Through holes slidably connected to the pressing block 111 are provided on both sides of the top plate 101, and a part of the pressing block 111 extends out of the through hole on the side away from the guide block 2 1111. The additional description of the pressing block 111 facilitates the doctor to squeeze the pressing block 111 to release the fixation of the wireless data transmission terminal 104 when disassembling the wireless data transmission terminal 104.

[0027] Working principle: Before use, place the wireless data transmission terminal 104 in the placement slot on the top of the top plate 101, press the wireless data transmission terminal 104, the positioning block 109 is squeezed by the wireless data transmission terminal 104 and slides to both sides, driving the guide block 1091 to slide and squeeze the limit spring 108, the guide block 1091 slides on the top of the transmission rod 110 and drives the transmission rod 110 to rotate, the transmission rod 110 drives the guide block 2 1111 to slide, the guide block 2 1111 drives the pressing block 111 to slide, when sliding to a certain position, the positioning block 109 enters the positioning slot of the wireless data transmission terminal 104, at this time the thrust of the limit spring 108 drives the positioning block 109 to slide. The positioning block 109 slides in the opposite direction to fix the wireless data transmission terminal 104. When in use, the patient's hand is placed on the support plate 301, and then the support plate 301 and the patient's hand are fixed by the elastic band 302. A line is drawn at the pulse pulsation, and then the positioning plate 401 is attached to the pulse pulsation so that the drawn line is located between the two lines of the transparent film 403. Then the wrist splint 1 is placed on the wrist so that the bottom plate 103 fits with the bottom of the support plate 301. The limiting block 402 is located in the limiting groove of the rubber gasket 107. The sensor 106 monitors the radial artery pressure and sends the data to the wireless data transmission terminal 104, which is then transmitted to the host 2 through the wireless data transmission terminal 104 and displayed on the display screen.
