Description

Technical Field

[0001] The invention belongs to the technical field of medical training models, and in particular relates to a multilateral integrated 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. It is approximately 21.2 cm long, with an outer diameter of approximately 0.3 cm at its origin. After branching off, the radial artery courses laterally and inferiorly, 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 deep beneath the tendons of the abductor pollicis longus and brevis to the back of the hand, where it enters the anatomical nasopharyngeal fossa. It then passes through the first metacarpal interspace into the deep palm. After branching off into the main thumb artery, it 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 flexor carpi radialis tendon, making it an ideal site for pulse palpation and puncture.

[0003] The lower segment of the radial artery is only covered by skin and fascia, and is the site where the pulse is palpated clinically. As vascular interventional surgery continues to be promoted in primary hospitals, more and more doctors need surgical training, and puncture techniques need to be gradually improved through practice. However, due to the importance patients place on their own arteriovenous fistulas, they all hope that medical staff with skilled puncture techniques can perform the puncture. Currently, medical beginners can only learn through lectures or videos, or by practicing on patients. Without a simulation training process, they cannot achieve truly proficient operation. 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. In addition, multiple arm models are not conducive to post-training inspection when they are not integrated, and the operation is more troublesome.

[0005] Based on this, the applicant considered designing a multilateral integrated radial artery puncture training device. Summary of the Invention

[0006] In view of the above problems, the present invention provides a multilateral integrated 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 multilateral integrated radial artery puncture training device includes a central pillar, a ring platform, a flip platform and a puncture model. The central pillar is cylindrical and vertically arranged. The ring platform is sleeved on the outer peripheral surface of the bottom of the central pillar. There are multiple flip platforms, and the multiple flip platforms are arranged in a circular array on the outer peripheral edge of the ring platform and can move and rotate along the outer peripheral surface of the ring platform. There are multiple puncture models, and the multiple puncture models are arranged one by one horizontally on the outside of the multiple flip platforms and hinged to the corresponding flip platforms. The puncture models can be rotated and erected upward around the flip platform.

[0008] Compared with the existing technology, the advantages of the multilateral integrated radial artery puncture training device of the present invention are:

[0009] By setting up the central pillar, ring platform, flip platform and puncture model, the puncture model can be rotated around the central pillar through the ring platform to adapt to different training positions. The puncture model can also be erected upward along the flip platform for storage, saving space on the bottom support plane. At the same time, multiple puncture models of different models can be installed on the central pillar at the same time, and can be quickly switched during training, greatly improving training efficiency. It can also support multiple people to train together, facilitate cyclic testing, and make operation simpler.

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

[0028] The present invention will be described in further detail below with reference to the accompanying drawings.

[0029] When implementing: Figure 1-8 As shown, the multilateral integrated radial artery puncture training device includes a central pillar 100, a ring platform 200, a flip platform 300 and a puncture model 400. The central pillar 100 is cylindrical and vertically arranged. The ring platform 200 is sleeved on the outer peripheral surface of the bottom of the central pillar 100. There are multiple flip platforms 300, and the multiple flip platforms 300 are arranged in a circular array on the outer peripheral edge of the ring platform 200 and can move and rotate along the outer peripheral surface of the ring platform 200. There are multiple puncture models 400, and the multiple puncture models 400 are correspondingly arranged horizontally on the outside of the multiple flip platforms 300 and hinged to the corresponding flip platforms 300. The puncture models 400 can be rotated and erected upward around the flip platform 300.

[0030] Compared with the existing technology, the advantages of the multilateral integrated radial artery puncture training device of the present invention are:

[0031] By providing the central pillar 100, the ring platform 200, the flip platform 300 and the puncture model 400, the puncture model 400 can be rotated around the central pillar 100 through the ring platform 200 to adapt to different training positions. The puncture model 400 can also be erected upward along the flip platform 300 for storage, saving space on the bottom support plane. At the same time, multiple puncture models 400 of different models can be installed on the central pillar 100 at the same time, and can be quickly switched during training, greatly improving training efficiency. It can also support multiple people to train together, facilitate cyclic testing, and make operation simpler.

[0032] The above-mentioned multilateral integrated radial artery puncture training device has the advantages of simple structure and easy implementation. It is suitable for installation and use in existing medical puncture training, and has low cost of use and can improve benefits.

[0033] In this embodiment, Figure 1-8 As shown, a lifting chamber 110 is provided in the central pillar 100, and a lifting mechanism is provided in the lifting chamber 110. The lifting mechanism is transmission-connected to the ring table 200 and is used to drive the ring table 200, the turning table 300 and the puncture model 400 to lift and lower at the same time.

[0034] In this way, through the provided lifting chamber 110 and the lifting mechanism, the lifting mechanism can drive the circular table 200, the turning table 300 and the puncture model 400 to rise and fall at the same time, so as to facilitate training for people of different heights and different postures, and improve training adaptability.

[0035] In this embodiment, Figure 1-8 As shown, the lifting mechanism includes a first motor 510, a transmission shaft 520 and a transmission block 530. The first motor 510 is installed on the top of the lifting chamber 110, and the transmission shaft 520 is vertically installed in the lifting chamber 110. One end of the transmission shaft 520 is coaxially connected to the rotating shaft of the first motor 510, and the other end is rotatably arranged on the bottom surface of the lifting chamber 110. A lifting bar hole is opened on the outer peripheral surface of the central pillar 100 at a position corresponding to the lifting chamber 110. The transmission block 530 is fixedly connected to the ring platform 200 through the lifting bar hole, and a transmission hole is provided on the transmission block 530. The transmission block 530 is threadedly connected to the transmission shaft 520 through the transmission hole.

[0036] In this way, by setting the first motor 510, the transmission shaft 520 and the transmission block 530, the first motor 510 can drive the transmission shaft 520 to rotate, thereby driving the transmission block 530 and the ring stage 200 to move up and down. The lifting structure is relatively simple and the lifting efficiency is high.

[0037] In this embodiment, Figure 1-8As shown, a locking mechanism is provided on the turning table 300 , and the locking mechanism is used to lock the turning table 300 on the ring table 200 to prevent relative movement between the turning table 300 and the ring table 200 .

[0038] In this way, the locking mechanism can lock the turning table 300 on the ring table 200 so that the turning table 300 does not rotate relative to the ring table 200 . The ring table 200 can also be controlled to rotate by controlling the turning table 300 .

[0039] In this embodiment, Figure 1-8 As shown, the locking mechanism includes a locking sleeve 610, a locking rod 620 and a compression spring 630. A positioning ring groove is provided on the top surface of the ring platform 200, and a plurality of locking holes 220 are provided in a circular array on the bottom surface of the positioning ring groove. The locking sleeve 610 is vertically installed on the flip table 300. The locking sleeve 610 includes a relatively closed end and an open end, and the open end is set downward. The locking rod 620 is slidably set in the locking sleeve 610, and the compression spring 630 is connected between the top end of the locking rod 620 and the closed end. The bottom end of the locking rod 620 can be inserted into a corresponding one of the locking holes 220 when sliding downward.

[0040] In this way, by setting the locking sleeve 610, locking rod 620 and compression spring 630, the locking rod 620 can slide in the locking sleeve 610 to switch the locking state between the ring table 200 and the flip table 300. The locking efficiency is high, and it can be pressed and locked by the compression spring 630, and the production cost is low.

[0041] In this embodiment, Figure 1-8 As shown, a positioning half hole 611 is provided on the top side wall of the locking sleeve 610, and a positioning rod 621 is provided laterally on the top of the locking rod 620. The positioning rod 621 can be rotated and inserted into the positioning half hole 611 after the locking rod 620 moves upward to position the upper and lower positions of the locking rod 620.

[0042] In this way, by setting the positioning half hole 611 and the positioning rod 621, the locking rod 620 can be fixed on the top of the locking sleeve 610 through the cooperation between the positioning rod 621 and the positioning half hole 611 when it is not locked, thereby avoiding accidental locking effect with the lock hole 220.

[0043] In this embodiment, Figure 1-8As shown, the puncture model 400 also includes a puncture needle 710. The puncture model 400 is provided with an upper simulated blood vessel 720 and a lower simulated blood vessel 730 that are interconnected. The upper simulated blood vessel 720 and the lower simulated blood vessel 730 are arranged horizontally in the puncture model 400, and the upper simulated blood vessel 720 is a transparent hose. The upper simulated blood vessel 720 is close to the upper surface of the puncture model 400. The puncture needle 710 can puncture into the upper simulated blood vessel 720 through the upper surface of the puncture model 400. An imaging tracking mechanism is provided at the bottom of the upper simulated blood vessel 720 for tracking and imaging the position of the puncture needle 710 in the upper simulated blood vessel 720 after the puncture needle 710 punctures into the upper simulated blood vessel 720.

[0044] In this way, through the set puncture needle 710, upper simulated blood vessel 720, lower simulated blood vessel 730 and imaging tracking mechanism, the puncture needle 710 can puncture into the upper simulated blood vessel 720 to train puncture. At the same time, the imaging tracking mechanism can track the position of the puncture needle 710 in real time to show the operator the current positional relationship between the puncture needle 710 and the upper simulated blood vessel 720, which facilitates timely feedback and adjustment, making training more efficient.

[0045] In this embodiment, Figure 1-8 As shown, the imaging tracking mechanism includes a sliding base 810, a second motor 820, a slide 830, a camera 840 and a magnetic field sensor 850. The sliding base 810 is fixedly installed at the bottom of the upper simulated blood vessel 720. The sliding base 810 includes a distal wrist end and a proximal wrist end relative to each other. The second motor 820 is installed at the distal wrist end. A transmission shaft 520 is provided in the sliding base 810. One end of the transmission shaft 520 is coaxially connected to the rotating shaft of the second motor 820, and the other end extends toward the proximal wrist end. The slide 830 is provided on the sliding base. The sliding base frame 810 is provided with a transmission hole in the sliding platform 830, and is connected to the transmission shaft 520 through the transmission hole. The camera 840 is installed on the top of the sliding platform 830, and the camera 840 can take images in the upper simulated blood vessel 720. The magnetic field sensor 850 is also provided on the top of the sliding platform 830. The needle head of the puncture needle 710 is made of a magnet. When the needle head of the puncture needle 710 punctures into the upper simulated blood vessel 720, it can be sensed by the magnetic field sensor 850.

[0046] In this way, by setting up the sliding base 810, the second motor 820, the slide 830, the camera 840 and the magnetic field sensor 850, the position of the magnetic needle head of the puncture needle 710 can be detected by the magnetic field sensor 850, and the slide 830 and the camera 840 are driven by the second motor 820 to move along with the needle head of the puncture needle 710, thereby realizing real-time monitoring of the needle head of the puncture needle 710.

[0047] During implementation, the starting position of the slide 830 and the magnetic field sensor 850 is the proximal wrist end of the sliding base 810, corresponding to the conventional radial artery puncture point.

[0048] During implementation, the imaging tracking mechanism also includes a display screen, and the camera 840 can transmit the video signal to the display screen, and the display screen displays the imaged video information.

[0049] During implementation, a single-chip microcomputer and Bluetooth are also provided on the slide 830. The single-chip microcomputer is used to receive signals from the magnetic field sensor 850 and control the opening and closing of the second motor 820. The Bluetooth is used to transmit the video signal captured by the camera 840 to the display screen.

[0050] In this embodiment, Figure 1-8 As shown, an injection cavity 120 and an injection pump 130 are provided at the top of the central pillar 100. The injection cavity 120 is arranged above the lifting cavity 110 for storing injection liquid. There are multiple injection pumps 130, and a ring array of multiple injection pumps 130 is arranged on the outer wall of the central pillar 100 and is connected to the injection cavity 120. The multiple injection pumps 130 are connected one-to-one with the multiple puncture models 400.

[0051] In this way, by providing the injection chamber 120 and the injection pump 130, a plurality of unintegrated arm models can be integrated for unified injection, thereby reducing production costs and making operations simpler.

[0052] During implementation, each infusion pump 130 is connected to the upper simulated blood vessel 720 and the lower simulated blood vessel 730 in the corresponding puncture model 400, so that the injection liquid can circulate from the infusion pump 130 through the upper simulated blood vessel 720 and the lower simulated blood vessel 730 and then return to the infusion pump 130.

[0053] In this embodiment, Figure 1-8 As shown, a liquid injection port 140 is provided on the top of the central pillar 100 , and the liquid injection port 140 is communicated with the liquid injection cavity 120 .

[0054] In this way, the liquid injection port 140 is provided so that liquid can be injected into the liquid injection cavity 120 through the liquid injection port 140 , making liquid injection and liquid storage simpler.

[0055] The above are only preferred embodiments of the present invention. It should be pointed out that various modifications and improvements made by those skilled in the art without departing from the present technical solution should also be deemed to fall within the scope of protection required by the claims.
