Description

Technical Field

[0001] The present invention relates to the field of medical technology, and specifically to a rapid blood pressure cuff device for the physical examination department of a hospital. Background Technique

[0002] Applying a blood pressure cuff means that when intravenous infusion or blood collection is required, a rubber tube is tightened locally to block the return of superficial veins, making the blood volume full, showing the veins, increasing the local filling of the veins, and being conducive to intravenous puncture. It is usually used for the preparatory work of intravenous injection. However, it should be noted that the arm should be in a clenched state when applying the blood pressure cuff, otherwise the blood vessel filling will not be obvious, which is not conducive to intravenous puncture.

[0003] Generally, when drawing blood in the physical examination department, a rubber tube is usually used to tie and bind to achieve the blood pressure cuff operation. When in use, not only is it easy to whip the arms of patients or medical staff due to the rapid rebound of the rubber tube when untying, but also there are significant differences in the fixing tightness of different medical staff for different patients, posing certain safety hazards.

By providing the height folding rotating frame 501, the frame shaft 502, the folding motor 503, the needle angle adjusting motor 504, the needle angle adjusting rotating block 505, the needle pushing guide groove 506, the needle pushing motor 507, the needle pushing screw 508, the needle pushing slider 509, the needle clamping slot 510, the threaded hole 511, the needle clamping electromagnet 512, the anti-slip sheet 513, the guide sliding frame 514, the needle clamping armature frame 515, the storage hole 516 and the reset tension spring 517, the needle insertion work can be realized through the cooperation of the folding motor 503, the needle angle adjusting motor 504, the needle pushing motor 507 and the probe 408 with medical staff.

[0034] Working principle: Before use, first start the moving motor 401. The moving motor 401 drives the threaded column 402 to rotate forward. When the threaded column 402 rotates forward, it pushes the threaded cylinder 405 so that the guide slider 403 and the angle bracket 404 move away from the mechanical shell 203, ensuring that the upper part of the buffer pad 110 close to the mechanical shell 203 is open. Then start the electric push rod 111. The electric push rod 111 pushes the lifting support plate 109 to lift and lower, thereby adjusting the height of the buffer pad 110. During use, the patient places the lower arm on the surface of the buffer pad 110, positions the upper arm inside the fixed perimeter frame 304 at a specified blood pressure cuff distance close to the elbow, and can adjust the angle of the rotating base 202 to match the patient's elbow bend. Then, the movable perimeter frame 309 is closed, and the electromagnetic lock 305 is opened to lock the movable perimeter frame 309. At this time, the patient's upper arm is pressed between the fixed expansion blood pressure cuff 315 and the movable expansion blood pressure cuff 316. The fixed expansion blood pressure cuff 315 is pressed into the fixed limit tube groove 306, and the movable expansion blood pressure cuff 316 is pressed into the movable limit tube groove 312. Then, the hydraulic pump 206 is started, and the distribution valve 207 is adjusted to pump the liquid. The transmission liquid inside the liquid storage bladder 204 passes through the distribution valve 207 along the third infusion tube 210, is pumped by the hydraulic pump 206, and then is distributed by the distribution valve 207 along the second infusion tube 209 to the pressure controller 205. Then, it enters the fixed expansion blood pressure cuff 315 from the first infusion tube 208, and then enters the movable expansion blood pressure cuff 316 from the fixed expansion blood pressure cuff 315 along the liquid guide hose 317, so that the fixed expansion blood pressure cuff 315 and the movable expansion blood pressure cuff 316 expand. The expanded fixed expansion blood pressure cuff 315 and movable expansion blood pressure cuff 316 squeeze the upper arm in the middle. If the hydraulic values of the fixed expansion blood pressure cuff 315 and the movable expansion blood pressure cuff 316 continue to be pressurized to reach the set value, the pressure controller 205 will be triggered at this time. The pressure controller 205 closes the liquid path to keep the pressure value at this size, thus achieving the compression of the vein; Then, the moving motor 401 is started. The moving motor 401 drives the threaded column 402 to reverse. When the threaded column 402 reverses, it pushes the threaded barrel 405, causing the guide slider 403 and the angle bracket 404 to move closer to the mechanical housing 203 until the blood vessel imager 407 stops near the specified needle insertion position. Then, the blood vessel imager 407 is turned on, and the blood vessel imager 407 emits light to irradiate the skin surface, thus achieving blood vessel imaging. Then, manual needle insertion or assisted needle insertion is performed; When assisting in needle insertion, insert the needle holding piece into the needle clamping slot 510, then energize the needle clamping electromagnet 512. When the needle clamping electromagnet 512 is energized, it attracts and closes the needle clamping armature frame 515. The needle clamping armature frame 515 slides out to fix the needle holding piece. The folding motor 503 drives the height folding bracket 501 to rotate to adjust the height of the needle. The needle angle adjustment motor 504 drives the needle angle adjustment block 505 to rotate to adjust the angle of the needle. Manually fix and adjust the patient's forearm so that the vein is located below the needle. Then drive the needle to adjust the height and angle and attach it to the surface of the patient's arm vein. Start the needle pushing motor 507 to push the needle. When the needle pushing motor 507 pushes the needle, the rotation of the needle pushing screw 508 drives the needle pushing slider 509 to slide along the direction of the needle. When pushing the needle, the feedback of the probe 408 is used to accurately control the depth of the needle pushing, and the angle is adjusted in real time through the needle angle adjustment motor 504, so as to push the needle into the vein. After the needle pushing is completed, cut off the power supply of the needle clamping electromagnet 512, and the needle clamping armature frame 515 pulls the needle clamping armature frame 515 to contract and reset. Then start the folding motor 503 and the needle angle adjustment motor 504 to lift the needle pushing slider 509, so that the device is separated from the needle.
