Description

Technical Field

[0001] The invention belongs to the technical field of medical training models, and in particular relates to a multi-segment radial artery puncture training 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 about 21.2 cm long and has an outer diameter of about 0.3 cm at the origin. After the brachial artery is separated, it runs outward and downward, first passing between the brachioradialis and pronator teres, then between the radial flexor carpi and the brachioradialis, and then to the lower end of the radius, obliquely passing through the deep surface of the tendons of the abductor pollicis longus and extensor pollicis brevis to the back of the hand to enter the anatomical nasopharyngeal fossa, and then passing through the first metacarpal space to enter the deep part of the palm. After the main thumb artery is separated, it anastomoses with the deep palmar branch of the ulnar artery to form the deep palmar arch. The radial artery is located shallowly between the lower end of the radius and the radial flexor carpi tendon, which is an ideal site for palpation and puncture.

[0003] The lower segment of the radial artery is only covered by skin and fascia, and is the part where the pulse is felt clinically. As vascular interventional surgery continues to be promoted to primary hospitals, more and more doctors need to receive surgical training, and puncture techniques need to be slowly practiced and improved. However, due to the importance that patients place on their own arteriovenous fistulas, they all hope that medical staff with skilled puncture techniques can perform the punctures. At present, medical beginners can only learn through lectures by teachers or by watching videos, or by practicing on patients. Without a simulated training process, they cannot achieve truly skilled operations. Therefore, radial artery puncture training arms are needed for medical staff to practice training.

[0004] The current puncture training arm only has a single arm model, and it is impossible to uniformly install multiple arm models of different models. At the same time, it is also impossible to quickly select and switch between multiple arm models of different models, resulting in slow training switching and low training efficiency. Multiple unintegrated arm models need to be performed separately during cyclic injection, which has a high production cost and is more troublesome to operate.

[0005] Based on this, the applicant considered designing a multi-segment radial artery puncture training device. Summary of the invention

[0006] In view of the above problems, the present invention provides a multi-segment radial artery puncture training device that overcomes the above problems or at least partially solves the above problems. The technical solution is as follows:

[0007] A multi-section radial artery puncture training device comprises an operating table, a liquid injection mechanism, a liquid storage mechanism, a turntable and a puncture model, wherein the operating table comprises a first side portion and a second side portion opposite to each other, the liquid injection mechanism and the liquid storage mechanism are both installed on the top surface of the operating table, the liquid injection mechanism is located on the first side portion of the operating table, the liquid storage mechanism is located between the first side portion and the second side portion, and the liquid injection mechanism and the liquid storage mechanism are connected to each other, the turntable is rotatably installed on the bottom surface of the operating table, a plurality of flipping mechanisms are arranged in a circular array on the outer edge of the turntable, the puncture model is installed on the flipping mechanism, and the flipping mechanism can flip the puncture model up and down when being driven by the turntable to the outside of the second side portion, and can be connected to the liquid storage mechanism when the puncture model is flipped upward.

[0008] Compared with the prior art, the multi-section radial artery puncture training device of the present invention has the following advantages:

[0009] By setting up the operating table, liquid injection mechanism, liquid storage mechanism, turntable, flipping mechanism and puncture model, multiple puncture models of different models can be placed on multiple flipping mechanisms for subsequent use, and the efficiency of selecting and switching puncture models is higher. At the same time, when using the puncture model, the corresponding puncture model is first rotated and adjusted to the outside of the second side, and then the puncture mechanism is flipped up by controlling the flipping mechanism, and finally the puncture model is connected to the liquid storage mechanism to perform puncture training. The efficiency of switching training between different models is improved, the liquid in the puncture model can be uniformly managed, and the operation is simple.

[0010] The multi-segment radial artery puncture training device has the advantages of simple structure and easy implementation, is suitable for installation and use in existing puncture training, and has low cost of use, which can improve benefits. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] In this embodiment, Figure 1-6As shown, the flipping mechanism includes a first motor 310 and a flipping arm 320, the first motor 310 is installed inside the outer edge of the turntable 200, the flipping arm 320 includes a relative connecting end and a free end, the flipping arm 320 is installed outside the outer edge of the turntable 200, and the connecting end is drivingly connected to the rotating shaft of the first motor 310, the flipping arm 320 includes a supporting surface, and the puncture model 400 is installed on the supporting surface.

[0028] In this way, by providing the first motor 310 and the flip arm 320 , the first motor 310 can be used to control the flip arm 320 to rotate, so as to control the upper and lower positions of the puncture model 400 . The control structure is simple and has strong stability.

[0029] In this embodiment, Figure 1-6 As shown, a raising platform 330 is provided on the supporting surface, and the puncture model 400 is installed on the top surface of the raising platform 330 .

[0030] In this way, by providing the raising platform 330, the puncture model 400 can match the height of the liquid storage mechanism after being turned over, making it easier to connect and use with less interference.

[0031] In this embodiment, Figure 1-6 As shown, a slide rail 340 is provided on the support surface of the flip arm 320 , and the raising platform 330 is slidably installed on the slide rail 340 .

[0032] In this way, by setting the slide rail 340, the flip arm 320 can adjust its position through the slide rail 340 after flipping so as to better connect the puncture model 400 and the liquid storage mechanism for use, further reducing connection interference, and having a simple structure and high efficiency.

[0033] In this embodiment, Figure 1-6 As shown, the raising platform 330 includes opposite abutting ends, the abutting ends face the rotating disk 200 , and a tightening spring 350 is disposed on the abutting ends.

[0034] In this way, by setting the pressing spring 350, the pressing spring 350 can give the puncture model 400 a certain outward thrust when the puncture model 400 is connected with the liquid storage mechanism, thereby increasing the connection sealing and liquid permeability between the puncture model 400 and the liquid storage mechanism.

[0035] During implementation, the pressing spring 350 is in a compressed state.

[0036] In this embodiment, Figure 1-6 As shown, the raising platform 330 further includes a force-applying end opposite to the abutting end, and a pull ring 360 is provided on the force-applying end.

[0037] In this way, by providing the pull ring 360 , when the raising platform 330 is moved along the slide rail 340 , the raising platform 330 can be pulled by the pull ring 360 , and the operation is more convenient.

[0038] In this embodiment, Figure 1-6 As shown, it also includes a puncture needle 410. The puncture model 400 is provided with an upper simulated blood vessel 420 and a lower simulated blood vessel 430 that are interconnected. The upper simulated blood vessel 420 and the lower simulated blood vessel 430 are horizontally arranged in the puncture model 400, and the upper simulated blood vessel 420 is a transparent hose. The upper simulated blood vessel 420 is close to the upper surface of the puncture model 400. The puncture needle 410 can puncture into the upper simulated blood vessel 420 through the upper surface of the puncture model 400. An imaging tracking mechanism is provided at the bottom of the upper simulated blood vessel 420 for tracking and imaging the position of the puncture needle 410 in the upper simulated blood vessel 420 after the puncture needle 410 punctures into the upper simulated blood vessel 420.

[0039] In this way, through the set puncture needle 410, upper simulated blood vessel 420, lower simulated blood vessel 430 and imaging tracking mechanism, the puncture needle 410 can puncture into the upper simulated blood vessel 420 to train puncture. At the same time, the imaging tracking mechanism can track the position of the puncture needle 410 in real time to show the operator the current positional relationship between the puncture needle 410 and the upper simulated blood vessel 420, which is convenient for timely feedback and adjustment, making the training more efficient.

[0040] In this embodiment, Figure 1-6 As shown, the imaging tracking mechanism includes a sliding base frame 510, a second motor 520, a slide 530, a camera 540 and a magnetic field sensor 550. The sliding base frame 510 is fixedly installed at the bottom of the upper simulated blood vessel 420. The sliding base frame 510 includes a distal wrist end and a proximal wrist end relative to each other. The second motor 520 is installed at the distal wrist end. A transmission shaft is arranged in the sliding base frame 510. One end of the transmission shaft is coaxially connected to the rotating shaft of the second motor 520, and the other end extends toward the proximal wrist end. The slide 530 is arranged on the sliding base frame 5 10, and can move along the length direction of the sliding base frame 510, a transmission hole is set in the slide 530, and is connected to the transmission shaft through the transmission hole, the camera 540 is installed on the top of the slide 530, and the camera 540 can take images in the upper simulated blood vessel 420, the magnetic field sensor 550 is also set on the top of the slide 530, the needle head of the puncture needle 410 is made of a magnet, when the needle head of the puncture needle 410 punctures into the upper simulated blood vessel 420, it can be sensed by the magnetic field sensor 550.

[0041] In this way, by setting up the sliding base 510, the second motor 520, the slide 530, the camera 540 and the magnetic field sensor 550, the position of the magnetic needle tip of the puncture needle 410 can be detected by the magnetic field sensor 550, and the second motor 520 drives the slide 530 and the camera 540 to move the needle tip of the puncture needle 410, thereby realizing real-time monitoring of the needle tip of the puncture needle 410.

[0042] During implementation, the starting position of the slide 530 and the magnetic field sensor 550 is the proximal wrist end of the sliding base 510, and corresponds to the conventional radial artery puncture point.

[0043] During implementation, the imaging tracking mechanism also includes a display screen, and the camera 540 can transmit the video signal to the display screen, and the display screen displays the imaged video information.

[0044] During implementation, a single-chip microcomputer and Bluetooth are also provided on the slide 530. The single-chip microcomputer is used to receive the signal of the magnetic field sensor 550 and control the opening and closing of the second motor 520, and the Bluetooth is used to transmit the video signal captured by the camera 540 to the display screen.

[0045] In this embodiment, Figure 1-6 As shown, the liquid storage mechanism includes an arm model 610, a liquid storage box 620 and a docking head 630. The puncture model 400 is provided with a connector at one end close to the liquid storage mechanism. The ends of the upper simulated blood vessel 420 and the lower simulated blood vessel 430 close to the connector are both penetrated to the outside of the connector. The arm model 610 is arranged on the operating table 100 and is located between the first side portion and the second side portion. The liquid storage box 620 is arranged in the arm model 610. The liquid storage box 620 includes opposite first ends and second ends. Two ends, the docking joint 630 is fixedly installed on the first end, and a return pipe 640 is arranged on the upper part of the docking joint 630. One end of the return pipe 640 is connected to the top of the liquid storage box 620, and the other end can be connected with the end of the upper simulated blood vessel 420 passing through the connector. A liquid outlet pipe 650 and a peristaltic pump 660 are also arranged on the docking joint 630. One end of the liquid outlet pipe 650 is connected to the bottom of the liquid storage pipe, and the other end passes through the peristaltic pump 660 and is connected with the end of the lower simulated blood vessel 430 passing through the connector.

[0046] In this way, the arm model 610, the liquid storage box 620 and the docking joint 630 are provided, so that the puncture model 400 can be connected with the liquid storage box 620 through the docking joint 630, so that the liquid in the liquid storage mechanism circulates into and out of the puncture model 400, so as to simulate the feeling when the puncture needle 410 contacts the body fluid. At the same time, the peristaltic pump 660 can simulate the pumping pulsation effect of the upper simulated blood vessel 420 after the liquid enters the upper simulated blood vessel 420, so as to better simulate the real pulse beating condition, and the training effect is closer to the real one.

[0047] During implementation, a plurality of sealing rings are sequentially arranged on the outer peripheral surface of the connector along the axial direction.

[0048] In this embodiment, Figure 1-6 As shown, the liquid injection mechanism includes a liquid injection box 710, a liquid injection tube 720, a liquid injection pump 730 and a solenoid valve 740. The liquid injection device is installed on the first edge portion. The liquid injection tube 720 is connected and arranged between the liquid injection box 710 and the liquid storage box 620. The liquid injection pump 730 is arranged in the liquid injection box 710 and corresponds to the liquid injection tube 720. The liquid injection pump 730 can pump the liquid in the liquid injection box 710 into the liquid storage box 620 through the liquid injection tube 720. The solenoid valve 740 is installed on the liquid injection tube 720 to control the flow rate of the liquid injection tube 720.

[0049] In this way, by setting up the injection box 710, the injection tube 720, the injection pump 730 and the electromagnetic valve 740, the liquid in the injection box 710 can be pumped into the liquid storage box 620. Since the pumping method between the liquid storage box 620 and the puncture model 400 is peristaltic, the pumping speed is slow, and the liquid exchange between the injection box and the liquid storage box 620 requires a faster speed. Therefore, directly using the injection pump 730 can make the liquid in the injection box 710 flow out to the liquid storage box 620 faster, and the injection effect is faster, and the electromagnetic valve 740 can stop the liquid exchange between the injection box 710 and the liquid storage box 620 when injection is not needed.

[0050] The above are only preferred implementations of the present invention. It should be pointed out that a number of modifications and improved technical solutions made by those skilled in the art without departing from the technical solution should also be deemed to fall within the scope of protection required by the claims.
