Abstract
Description
Radial artery measurement device Technical Field
[0001] The present invention relates to the technical field of medical equipment, and in particular to a radial artery measuring device. Background Art
[0002] The radial artery is one of the terminal branches of the brachial artery and is slightly smaller than the ulnar artery. The radial artery is approximately 21.2 cm long, with an outer diameter of approximately 0.3 cm at its origin. After branching off, the brachial artery runs outward and downward, first passing between the brachioradialis and pronator teres muscles, then between the flexor carpi radialis and brachioradialis muscles. At the lower end of the radius, it passes obliquely through the deep surface of the tendons of the abductor pollicis longus and brevis to the back of the hand and enters the anatomical nasopharyngeal fossa. It then passes through the first metacarpal space deep into the palm and, after branching off the main thumb artery, anastomoses with the deep palmar branch of the ulnar artery to form the deep palmar arch. The radial artery is located superficially between the lower end of the radius and the tendon of the flexor carpi radialis, making it an ideal site for pulse palpation and puncture. The radial artery is constantly accompanied by two veins. A straight line drawn from 2.5 cm below the center of the cubital fossa outward and downward to the inner side of the radial styloid process is the surface projection of the radial artery. The radial artery is located shallowly between the lower end of the radius and the radial flexor carpi tendon, making it an ideal site for pulse palpation and puncture. The lower segment of the radial artery is only covered by the skin and fascia and is the site for clinical pulse palpation. The radial artery is generally measured using a radial artery measuring device to detect the patient's physical condition. Technical issues
[0003] The existing radial artery measurement device is not convenient for supporting and fixing the hand during use, which easily leads to the movement of the hand during the measurement process, resulting in a decrease in measurement accuracy. In addition, the existing radial artery measurement device has insufficient measurement accuracy and is not convenient for accurately measuring the radial artery pulse. Technical Solutions

[0026] Specifically, the forearm can be supported by the support plate 1 on the top of the base plate 4, and the arm placed above the support plate 1 can be protected by the protective pad 11 on the top of the support plate 1, which plays a buffering role and improves the practicality of the radial artery measuring device.
[0027] The radial artery measuring device body 2 is fixedly installed on the top of the support frame 12, and a telescopic rod 21 is fixedly installed in the middle of the bottom of the radial artery measuring device body 2. A lower pressure plate 22 is fixedly installed at the bottom of the telescopic rod 21. The lower pressure plate 22 is in a "C" shape. A photoelectric sensor 23 is fixedly installed in the middle of one side of the lower pressure plate 22, and a connecting line 24 is fixedly installed on the top of the photoelectric sensor 23.
[0028] Specifically, by extending and retracting the telescopic rod 21, the lower pressure plate 22 is pushed downward, so that the lower pressure plate 22 fits the middle of the forearm, and the radial artery in the middle of the forearm is measured by the photoelectric sensor 23 in the middle of the lower pressure plate 22. It is connected to the radial artery measuring device body 2 through the connecting line 24, so that the detected data is sent to the inside of the radial artery measuring device body 2. By clamping the lower pressure plate 22, the problem of reduced measurement accuracy due to arm movement is avoided, thereby improving the practicality of the radial artery measuring device.
[0029] A drawstring 3 is fixedly installed inside the fixing block 14 , and two Velcro blocks 31 are fixedly installed on both sides of one side of the drawstring 3 .

[0036] Specifically, the radial artery measuring device is adsorbed on the desktop by the suction cups 42 under the two support blocks 41 on both sides of the bottom of the base plate 4, thereby fixing the radial artery measuring device. When the radial artery measuring device needs to be removed, the sealing port 44 on one side of the connecting tube 43 is pulled to allow the outside air to enter the inside of the connecting tube 43, and the air is sent from the support block 41 into the suction cup 42 through the connecting tube 43, so that the air pressure inside the suction cup 42 is the same as that of the outside, so that the radial artery measuring device can be removed, thereby improving the convenience of the radial artery measuring device and avoiding the problem that the suction cup 42 is inconvenient to remove after being adsorbed.
[0037] A sliding frame 5 is fixedly installed in the middle of the top of the support plate 1, and a sliding block 51 is movably connected in the middle of the sliding frame 5. A lifting rod 52 is fixedly installed inside the sliding block 51, and a spring 53 is fixedly installed at the bottom of the lifting rod 52. A damper 54 is movably connected inside the spring 53, and a rotating shaft 55 is fixedly installed at the bottom of the damper 54. A pulse sensor 56 is fixedly installed at the bottom of the rotating shaft 55.
[0038] Specifically, the position of the pulse sensor 56 can be adjusted by sliding the sliding block 51 inside the sliding frame 5. By lowering the lifting rod 52, the pulse sensor 56 can be pushed to fit the radial artery of the arm. By contracting the rotating shaft 5 and the spring 53, the pulse sensor 56 can be pressed against the arm.
[0039] Working principle: First, the radial artery measuring device is adsorbed on the desktop through the suction cups 42 under the two support blocks 41 on both sides of the bottom of the bottom plate 4, so as to fix the radial artery measuring device. When the radial artery measuring device needs to be removed, the sealing port 44 on one side of the connecting tube 43 is pulled to allow the outside air to enter the inside of the connecting tube 43, and the air is sent from the support block 41 into the suction cup 42 through the connecting tube 43, so that the air pressure inside the suction cup 42 is the same as that of the outside, so that the radial artery measuring device can be removed, which improves the convenience of the radial artery measuring device and avoids the problem of being inconvenient to remove after the suction cup 42 is adsorbed. The forearm can be supported by the support plate 1 on the top of the bottom plate 4, and the protective pad 11 on the top of the support plate 1 can be used to protect the radial artery measuring device. The arm above the support plate 1 is protected and acts as a buffer, thereby improving the practicality of the radial artery measuring device. The telescopic rod 21 in the middle of the bottom of the radial artery measuring device body 2 passes through the mounting hole 13 in the middle of the support frame 12. The telescopic rod 21 is extended and retracted to push the lower pressing plate 22 downward, so that the lower pressing plate 22 fits the middle of the forearm. The radial artery in the middle of the forearm is measured by the photoelectric sensor 23 in the middle of the lower pressing plate 22. The radial artery is connected to the radial artery measuring device body 2 through the connecting line 24, so that the detected data is sent to the inside of the radial artery measuring device body 2. The problem of reduced measurement accuracy due to arm movement is avoided by clamping the lower pressing plate 22, thereby improving the practicality of the radial artery measuring device. The wrist is tightened by the strap 3 The strap 3 is fixed at the wrist, and is adsorbed by the Velcro plate 32 and the Velcro block 31, so that the strap 3 can be wrapped and fixed to the wrist. The strap 3 is fixed to the top of the protective cushion 11 through the fixing block 14, and the radial artery at the wrist is measured by the photoelectric sensor 34 inside the connecting block 33 on one side of the strap 3. The output line 35 is connected to the radial artery measuring device body 2, so that the detected data can be transmitted to the radial artery measuring device body 2, and the radial artery of the arm is measured by the photoelectric sensor 23 and the radial artery of the wrist is measured by the photoelectric sensor 34, thereby improving the measurement accuracy of the radial artery measuring device. When the strap 3 continues to wrap around the wrist, the operation of the micro air pump 37 can absorb the outside air from the connecting block 33 on the top of the strap 3. The hose is blown into the interior of the airbag wrapping member 36, thereby inflating the airbag wrapping member 36, so that the airbag wrapping member 36 wraps the wrist, thereby improving the fixing effect of the arm, and the sliding block 51 slides left and right inside the sliding frame 5, thereby moving the pulse sensor 56 to the top of the radial artery, and the pulse sensor 56 is pushed down by the descent of the lifting rod 52. When the pulse sensor 56 fits the top of the wrist, the pulse sensor 56 rotates through the rotation of the rotating shaft 55, so that it can better fit the curvature of the arm, so as to accurately detect the radial artery pulse, and the clamping effect is improved by the contraction of the spring 53, and the contracted spring 53 is supported by the contraction of the damper 54.The problem of the spring 53 being offset is avoided, and the practicality of the device is improved.
