Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of medical training models, and particularly relates to a multi-edge integrated radial artery puncture training device. BACKGROUND

[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 the outer diameter of the starting end is about 0.3 cm. After the brachial artery branches out, it runs outward and downward, first between the brachioradialis muscle and the pronator quadratus muscle, then between the flexor carpi radialis muscle and the brachioradialis muscle, to the lower end of the radius, obliquely through the deep surface of the long and short extensor muscles of the thumb, to the back of the hand, into the anatomical nasopharynx, through the first intermetacarpal space into the deep part of the palm, and after the main artery of the thumb branches out, 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 tendon of the flexor carpi radialis muscle, which is the ideal site for palpation and puncture.

[0003] The lower segment of the radial artery is only covered by skin and fascia, which is the site for palpating the pulse. With the continuous promotion of vascular intervention surgery to primary hospitals, more and more doctors need to undergo surgery training, and puncture technology needs to be gradually improved. However, due to the importance that patients attach to autologous arteriovenous fistula, they hope that medical personnel with skilled puncture technology will perform puncture. Currently, medical beginners can only learn through teacher lectures or video watching, or practice on patients, lacking a simulation training process, which cannot achieve truly skilled operation. Therefore, a radial artery puncture training arm is needed for medical personnel to practice and train.

[0004] The current puncture training arm only has a single arm model, which cannot uniformly install multiple arm models of different sizes, and cannot quickly select and switch between multiple arm models of different sizes, resulting in slow training switching and low training efficiency. Moreover, multiple arm models in an un-integrated state are not conducive to post-training inspection and are cumbersome to operate.

[0005] Therefore, the applicant considered designing a multi-edge integrated radial artery puncture training device. SUMMARY

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

[0033] In the embodiment, as shown in the figure, Figures 1-8 The lifting cavity 110 is arranged in the center support 100, the lifting mechanism is arranged in the lifting cavity 110, the lifting mechanism is in transmission connection with the ring table 200, and the ring table 200, the turnover table 300 and the puncture model 400 are driven to lift at the same time.

[0034] In this way, the lifting cavity 110 and the lifting mechanism are arranged, so that the lifting mechanism can drive the ring table 200, the turnover table 300 and the puncture model 400 to lift at the same time, so as to train people of different heights and postures, and the training adaptability is better.

[0035] In the embodiment, as shown in the figure, Figures 1-8 The lifting mechanism includes a first motor 510, a transmission shaft 520 and a transmission block 530, the first motor 510 is installed at the top of the lifting cavity 110, the transmission shaft 520 is vertically installed in the lifting cavity 110, one end of the transmission shaft 520 is in coaxial transmission connection with the rotating shaft of the first motor 510, the other end is rotationally arranged on the bottom surface of the lifting cavity 110, a lifting hole is formed in the position of the lifting cavity 110 on the outer circumferential surface of the center support 100, the transmission block 530 is fixedly connected with the ring table 200 through the lifting hole, a transmission hole is formed in the transmission block 530, and the transmission block 530 is in threaded transmission connection with the transmission shaft 520 through the transmission hole.

[0037] In the embodiment, as shown in the figure, Figures 1-8As shown, the turnover table 300 is provided with a locking mechanism, which is used to lock the turnover table 300 on the ring table 200 to avoid relative movement between the turnover table 300 and the ring table 200.

[0038] In this way, the locking mechanism can lock the turnover table 300 on the ring table 200, so that the turnover table 300 cannot rotate relative to the ring table 200, and the rotation of the ring table 200 can be controlled by controlling the turnover table 300.

[0039] In this embodiment, as shown in the figure, Figures 1-8 The locking mechanism includes a locking sleeve 610, a locking rod 620, and a compression spring 630.

The locking rod 620 has a positioning rod 621 transversely arranged on the top. The positioning rod 621 can be inserted into the positioning half-hole 611 after the locking rod 620 is upwardly moved and rotated, so as to position the up-down position of the locking rod 620.

[0042] In this way, the positioning half-hole 611 and the positioning rod 621 can fix the locking rod 620 on the top of the locking sleeve 610 when not locked, so as to avoid accidental locking effect with the lock hole 220.

[0043] In this embodiment, as shown in the figure, Figures 1-8As shown, the puncture model 400 further comprises a puncture needle 710, the puncture model 400 is provided with an upper simulation blood vessel 720 and a lower simulation blood vessel 730 which are communicated with each other, the upper simulation blood vessel 720 and the lower simulation blood vessel 730 are transversely arranged in the puncture model 400, the upper simulation blood vessel 720 is a transparent hose, the upper simulation blood vessel 720 is close to the upper surface of the puncture model 400, the puncture needle 710 can puncture into the upper simulation blood vessel 720 through the upper surface of the puncture model 400, and the bottom of the upper simulation blood vessel 720 is provided with an imaging tracking mechanism for tracking and imaging the position of the puncture needle 710 in the upper simulation blood vessel 720 after the puncture needle 710 punctures into the upper simulation blood vessel 720.

[0044] In this way, by arranging the puncture needle 710, the upper simulation blood vessel 720, the lower simulation blood vessel 730 and the imaging tracking mechanism, the puncture needle 710 can puncture into the upper simulation blood vessel 720 to train puncture, and the imaging tracking mechanism can track the position of the puncture needle 710 in real time to display the current position relationship between the puncture needle 710 and the upper simulation blood vessel 720 to the operator, so as to facilitate timely feedback and adjustment, and the training is more efficient.

[0045] In this embodiment, as shown in the figure, Figures 1-8 The imaging tracking mechanism comprises a sliding chassis 810, a second motor 820, a sliding table 830, a camera 840 and a magnetic field sensor 850, the sliding chassis 810 is fixedly installed at the bottom of the upper simulation blood vessel 720, the sliding chassis 810 comprises opposite distal and proximal ends, the second motor 820 is installed at the distal end, the sliding chassis 810 is provided with a transmission shaft 520, one end of the transmission shaft 520 is coaxially and drivingly connected with the rotating shaft of the second motor 820, and the other end extends to the proximal end, the sliding table 830 is arranged in the sliding chassis 810 and can move along the length direction of the sliding chassis 810, the sliding table 830 is provided with a transmission hole and is drivingly connected with the transmission shaft 520 through the transmission hole, the camera 840 is installed at the top of the sliding table 830, the camera 840 can shoot the image in the upper simulation blood vessel 720, and the magnetic field sensor 850 is also arranged at the top of the sliding table 830, the needle of the puncture needle 710 is made of a magnet, and when the needle of the puncture needle 710 punctures into the upper simulation blood vessel 720, the needle can be sensed by the magnetic field sensor 850.

The second motor 820 drives the slide table 830 and the camera 840 to move with the needle tip of the puncture needle 710, thereby achieving real-time monitoring of the needle tip of the puncture needle 710.

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

[0048] In practice, the imaging tracking mechanism also includes a display screen, through which the camera 840 transmits video signals, and the display screen shows the video information after imaging.

[0049] During implementation, the slide table 830 is also equipped with a microcontroller and Bluetooth.

[0051] In this way, the injection chamber 120 and injection pump 130 can be set up to integrate multiple unintegrated arm models for unified injection, reducing manufacturing costs and simplifying operation.

[0052] During implementation, each injection 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 solution can circulate from the injection pump 130 through the upper simulated blood vessel 720 and the lower simulated blood vessel 730 and then return to the injection pump 130.

[0053] In this embodiment, as Figures 1-8 As shown, the top of the central support 100 is provided with an injection port 140, which is connected to the injection chamber 120.
