Description

Technical Field

[0001] This invention belongs to the field of medical training model technology, specifically relating to a multi-segment radial artery puncture training device. Background Technology

[0002] The radial artery is one of the terminal branches of the brachial artery, slightly smaller than the ulnar artery. It is approximately 21.2 cm long with an initial external diameter of about 0.3 cm. After branching off, the brachial artery runs downwards and outwards, first between the brachioradialis and pronator teres muscles, then between the flexor carpi radialis and brachioradialis muscles, until it reaches the lower end of the radius, obliquely passing deep to the tendons of the abductor pollicis longus and extensor pollicis brevis muscles, entering the anatomical nasopharyngeal fossa on the posterior aspect of the hand. It then passes through the first metacarpal space into the deep palm, where it branches off as the main artery of the thumb, anastomosing with the deep palmar branch of the ulnar artery to form the deep palmar arch. The radial artery is relatively superficial between the lower end of the radius and the tendon of the flexor carpi radialis, making it an ideal site for palpation and puncture.

[0003] The lower segment of the radial artery, covered only by skin and fascia, is a crucial site for clinical pulse diagnosis. With the increasing prevalence of interventional vascular surgery in primary care hospitals, more and more doctors require surgical training, and their puncture techniques need gradual practice to improve. Furthermore, due to patients' emphasis on autogenous arteriovenous fistulas, they prefer to have experienced medical personnel perform the punctures. Currently, medical beginners can only learn through lectures, videos, or practice on patients, lacking simulated training to achieve true proficiency. Therefore, a training arm for radial artery puncture is needed for medical personnel to practice on.

[0004] Currently, the puncture training arm only has a single arm model, making it impossible to uniformly install multiple different arm models. It also makes it difficult to quickly select and switch between multiple different arm models, resulting in slow training switching and low training efficiency. Furthermore, multiple unintegrated arm models need to be used separately for cyclic injection, which increases production costs and makes the operation more complicated.

[0005] Based on this, the applicant is considering 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 or at least partially solves the above problems, the technical solution of which is as follows:

[0007] A multi-segment radial artery puncture training device includes an operating table, an injection mechanism, a storage mechanism, a turntable, and a puncture model. The operating table includes a first side and a second side facing each other. The injection mechanism and the storage mechanism are both mounted on the top surface of the operating table. The injection mechanism is located on the first side of the operating table, and the storage mechanism is located between the first side and the second side, and the injection mechanism and the storage mechanism are interconnected. The turntable is rotatably mounted on the bottom surface of the operating table. Multiple flipping mechanisms are arranged in a circular array on the outer edge of the turntable. The puncture model is mounted on the flipping mechanism. When the flipping mechanism is moved outside the second side by the turntable, it can flip the puncture model up and down. When the puncture model is flipped upward, it can connect with the storage mechanism.

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

[0009] The system incorporates an operating platform, injection mechanism, storage mechanism, turntable, flipping mechanism, and puncture model. This allows multiple puncture models of different types to be placed on multiple flipping mechanisms for later use, improving the efficiency of selecting and switching puncture models. When using a puncture model, the corresponding model is first rotated and adjusted to the outside of the second side. Then, the flipping mechanism is controlled to flip the puncture model up. Finally, the puncture model is connected to the storage mechanism for puncture training. This improves the efficiency of switching training between different models, allows for unified management of the liquid in the puncture model, and simplifies operation.

[0010] The aforementioned multi-segment radial artery puncture training device has the advantages of simple structure and easy implementation. It is suitable for installation and use in existing puncture training, and the cost of use is low, which can improve efficiency. Attached Figure Description

[0025] The present invention will now be described in further detail with reference to the accompanying drawings.

[0026] In practical implementation: such as Figure 1-6 As shown, a multi-segment radial artery puncture training device is characterized by comprising an operating table 100, an injection mechanism, a storage mechanism, a turntable 200, and a puncture model 400. The operating table 100 includes a first side and a second side opposite to each other. The injection mechanism and the storage mechanism are both mounted on the top surface of the operating table 100. The injection mechanism is located on the first side of the operating table 100, and the storage mechanism is located between the first side and the second side, and the injection mechanism and the storage mechanism are interconnected. The turntable 200 is rotatably mounted on the bottom surface of the operating table 100. Multiple flipping mechanisms are arranged in a circular array on the outer edge of the turntable 200. The puncture model 400 is mounted on the flipping mechanism. The flipping mechanism can flip the puncture model 400 up and down when it is driven by the turntable 200 to the outside of the second side. When the puncture model 400 is flipped upward, it can connect with the storage mechanism.

[0027] In this embodiment, as 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 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 connected to the rotating shaft of the first motor 310. The flipping arm 320 includes a support surface, and the puncture model 400 is installed on the support surface.

[0028] In this way, by setting the first motor 310 and the flipping arm 320, the first motor 310 can control the rotation of the flipping arm 320 to control the up and down position of the puncture model 400. The control structure is simple and has strong stability.

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

[0030] In this way, by setting up the raised platform 330, the height of the puncture model 400 can be matched with that of the liquid storage mechanism after it is flipped over, making it easier to connect and use with less interference.

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

[0032] In this way, by using the slide rail 340, the tilting arm 320 can be adjusted in position after tilting to better connect the puncture model 400 and the liquid storage mechanism, further reducing connection interference, and resulting in a simple structure and high efficiency.

[0033] In this embodiment, as Figure 1-6 As shown, the raised platform 330 includes opposing abutting ends facing the turntable 200, and a retaining spring 350 is provided on the abutting end.

[0034] In this way, the clamping spring 350 can provide a certain outward pushing force to the puncture model 400 when it is connected to the liquid storage mechanism, thereby increasing the sealing and liquid flow between the puncture model 400 and the liquid storage mechanism.

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

[0036] In this embodiment, as Figure 1-6 As shown, the raised platform 330 also 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, the pull ring 360 makes it easier to move the raised platform 330 along the slide rail 340 by pulling the raised platform 330.

[0038] In this embodiment, as Figure 1-6 As shown, it also includes a puncture needle 410. The puncture model 400 has 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 arranged laterally in the puncture model 400. The upper simulated blood vessel 420 is a transparent tube. The upper simulated blood vessel 420 is close to the upper surface of the puncture model 400. The puncture needle 410 can puncture and enter 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 enters the upper simulated blood vessel 420.

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

[0040] In this embodiment, as Figure 1-6 As shown, the imaging tracking mechanism includes a sliding base 510, a second motor 520, a slide table 530, a camera 540, and a magnetic field sensor 550. The sliding base 510 is fixedly installed at the bottom of the upper simulated blood vessel 420. The sliding base 510 includes a distal wrist end and a proximal wrist end. The second motor 520 is installed at the distal wrist end. A drive shaft is provided inside the sliding base 510. One end of the drive shaft is coaxially connected to the rotating shaft of the second motor 520, and the other end extends towards the proximal wrist end. The slide table 530 is disposed on the sliding base 510. Within 10, it can move along the length of the sliding base 510. The slide table 530 is provided with a transmission hole and is connected to the transmission shaft through the transmission hole. The camera 540 is installed on the top of the slide table 530 and can capture images inside the upper simulated blood vessel 420. The magnetic field sensor 550 is also located on the top of the slide table 530. The needle tip of the puncture needle 410 is made of magnet. When the needle tip 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 using the sliding base 510, the second motor 520, the slide table 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. Then, the second motor 520 drives the slide table 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 table 530 and the magnetic field sensor 550 is near the wrist end of the sliding base 510, corresponding to the conventional radial artery puncture point.

[0043] In practice, the imaging tracking mechanism also includes a display screen, through which the camera 540 transmits video signals, and the display screen shows the video information after imaging.

[0044] During implementation, the slide table 530 is also equipped with a microcontroller and Bluetooth. The microcontroller is used to receive signals from the magnetic field sensor 550 and control the opening and closing of the second motor 520, while Bluetooth is used to transmit video signals captured by the camera 540 to the display screen.

[0045] In this embodiment, as Figure 1-6 As shown, the fluid storage mechanism includes an arm model 610, a fluid storage tank 620, and a connector 630. A connector is provided at one end of the puncture model 400 near the fluid storage mechanism. The ends of the upper simulated blood vessel 420 and the lower simulated blood vessel 430 near the connector both extend beyond the connector. The arm model 610 is mounted on the operating table 100 and located between the first and second sides. The fluid storage tank 620 is disposed within the arm model 610 and includes opposing first and second ends. At both ends, the connector 630 is fixedly installed on the first end. A return pipe 640 is provided on the upper part of the connector 630. One end of the return pipe 640 is connected to the top of the liquid storage tank 620, and the other end is connected to the end of the upper simulated blood vessel 420 that extends out of the connector. The connector 630 is also provided with an outlet pipe 650 and a peristaltic pump 660. One end of the outlet pipe 650 is connected to the bottom of the liquid storage tank, and the other end passes through the peristaltic pump 660 and is connected to the end of the lower simulated blood vessel 430 that extends out of the connector.

[0046] In this way, through the designed arm model 610, fluid storage tank 620, and connector 630, the puncture model 400 can be connected to the fluid storage tank 620 via the connector 630, allowing the fluid circulation mechanism within the fluid storage device to flow in and out of the puncture model 400, simulating the sensation of the puncture needle 410 contacting bodily fluids. Simultaneously, the peristaltic pump 660 simulates the pumping pulsation effect produced in the simulated blood vessel 420 after the fluid enters, better mimicking the real pulse and resulting in a more realistic training effect.

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

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

[0049] In this way, through the injection tank 710, injection pipe 720, injection pump 730 and solenoid valve 740, the liquid in the injection tank 710 can be pumped into the storage tank 620. Since the pumping method between the storage tank 620 and the puncture model 400 is peristaltic, the pumping speed is relatively slow. However, the liquid exchange between the injection tank and the storage tank 620 requires a faster speed. Therefore, the injection pump 730 can make the liquid in the injection tank 710 flow out to the storage tank 620 faster, and the injection effect is faster. The solenoid valve 740 can stop the liquid exchange between the injection tank 710 and the storage tank 620 when injection is not needed.

[0050] The above are merely preferred embodiments of the present invention. It should be noted that any modifications and improvements made by those skilled in the art without departing from the present technical solution should also be considered to fall within the scope of protection claimed in this claim.
