Description

Technical Field

[0001] This invention relates to the field of medical technology, specifically to a rapid pulse pressure device for use in hospital physical examination departments. Background Technology

[0002] Pulse compression refers to the use of a rubber tube to tighten the local area when intravenous infusion or blood collection is required. This can block the return flow of superficial veins, making the veins more visible and increasing local venous filling, which is conducive to venipuncture. It is usually used for the preparation of intravenous injection. However, it should be noted that the arm should be clenched when compressing the pulse, otherwise the venous filling will not be obvious, which will not be conducive to venipuncture.

[0003] When drawing blood in a physical examination department, a rubber tube is usually used to apply pressure to the pulse. However, when untying the tube, the rapid rebound of the rubber tube can easily hit the patient's or medical staff's arm. Furthermore, the tightness of the fixation varies greatly between different medical staff and different patients, posing certain safety hazards. Summary of the Invention

Through its placement mechanism, pressure adapter, pulse compression mechanism, imaging mechanism, and needle insertion assistance mechanism, the device can compress veins by expanding the pulse compression mechanism using the pressure adapter. This not only avoids the rubber tube rebounding and hitting the patient when the pressure is released, but also ensures that the pressure is adjustable, thus improving safety.

Through its rotating shaft, rotating seat, mechanical housing, reservoir, pressure controller, hydraulic pump, distribution valve, first infusion tube, second infusion tube, and third infusion tube, it can not only adjust the appropriate angle according to the patient's elbow flexion, but also provide pressure and safety during pulse-pressing to ensure that the tightness of each pulse-pressing is close to consistent.

[0045] Working principle:

[0046] 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 to make the guide slider 403 and the corner bracket 404 move away from the mechanical housing 203, ensuring that the buffer pad 110 is open above the mechanical housing 203. Then start the electric push rod 111. The electric push rod 111 pushes the lifting support plate 109 to rise and fall, thereby adjusting the height of the buffer pad 110.

[0047] In use, the patient places their forearm on the surface of the cushioning pad 110, and positions their upper arm close to the elbow at the prescribed pressure point within the fixed frame 304. The angle of the rotating seat 202 can be adjusted to accommodate the patient's elbow flexion. Then, the movable frame 309 is closed, and the electromagnetic lock 305 is engaged to lock it. At this point, the patient's upper arm is pressed between the fixed expansion pressure tube 315 and the movable expansion pressure tube 316, with the fixed expansion pressure tube 315 pressed into the fixed limit tube groove 306 and the movable expansion pressure tube 316 pressed into the movable limit tube groove 312. The hydraulic pump 206 is then activated, and the dispensing valve 207 is adjusted to pump fluid. The transmission fluid inside the reservoir 204 flows along the third infusion tube 210, passes through the dispensing valve 207, and is pumped by the hydraulic pump 206. After delivery, the fluid is distributed by the distribution valve 207 along the second infusion tube 209 to the pressure controller 205, and then enters the constant expansion pressure tube 315 from the first infusion tube 208. From the constant expansion pressure tube 315, it enters the dynamic expansion pressure tube 316 along the fluid guide tube 317, thereby causing the constant expansion pressure tube 315 and the dynamic expansion pressure tube 316 to expand. The expanded constant expansion pressure tube 315 and the dynamic expansion pressure tube 316 compress the middle large arm. If the hydraulic pressure value of the constant expansion pressure tube 315 and the dynamic expansion pressure tube 316 continues to increase to the set value, the pressure controller 205 will be triggered. The pressure controller 205 closes the fluid circuit, so that the pressure value is maintained at that value, thereby achieving compression of the vein.

[0048] Then, the moving motor 401 is started, which drives the threaded column 402 to reverse. When the threaded column 402 reverses, it pushes the threaded cylinder 405 to move the guide slider 403 and the bracket 404 closer to the mechanical housing 203 until the vascular imaging device 407 reaches the vicinity of the designated needle insertion position and stops. Then, the vascular imaging device 407 is turned on, and the vascular imaging device 407 emits light to illuminate the skin surface, thereby realizing vascular imaging. Then, manual or assisted needle insertion is performed.

[0049] During assisted acupuncture, insert the needle gripper into the needle clamping suture 510, then energize the needle clamping electromagnet 512. The energized electromagnet 512 attracts the needle clamping armature frame 515, which slides out to secure the needle gripper. The folding motor 503 drives the height folding frame 501 to rotate and adjust the needle height. The needle angle adjustment motor 504 drives the needle angle adjustment block 505 to rotate and adjust the needle angle. Manually fix and adjust the patient's forearm so that the vein is below the needle. Then, drive the needle to adjust the coverage and angle, place it on the surface of the vein in the patient's arm, and initiate the needle insertion. The motor 507 pushes the needle. When the needle is pushed, the rotation of the needle-pushing screw 508 drives the needle-pushing slider 509 to slide along the direction of the needle. During the push, the depth of the push is precisely controlled by the feedback of the probe 408, and the angle is adjusted in real time by the needle angle adjustment motor 504, so as to push the needle into the vein. After the push is completed, the needle clamping electromagnet 512 is de-energized, the needle clamping armature frame 515 is pulled to retract and reset, and then the folding motor 503 and the needle angle adjustment motor 504 are started to lift the needle-pushing slider 509, so that the device is separated from the needle.
