Description

Technical Field

[0001] This invention relates to the field of medical device technology, specifically to a portable, assembled mannequin. Background Technology

[0002] Medical training mannequins are auxiliary tools used in medical teaching and training, and come in various types depending on their complexity. Simple mannequins are generally made of rubber, plastic, etc., and their appearance roughly mimics the human body, with structures such as a torso and limbs. They can meet the needs of basic medical operation training. For example, during injection practice, their skin has a certain degree of elasticity, allowing the syringe to pierce and simulate drug injection. They can also be used for bandaging training and palpation practice in basic physical examination teaching. They are low in cost, simple in structure, and suitable for beginners to familiarize themselves with operating procedures.

[0003] Currently, most mannequins used in medical training are designed as single, integrated structures. Specifically, these mannequins are either individually designed parts, such as single-arm mannequins simulating only the shape and function of a human arm, or single-leg mannequins focusing on leg features; or they are complete mannequins representing the entire human body. However, in actual medical training, the training content is diverse, and the requirements for mannequin limbs are complex and varied. Different medical operation training scenarios and different disease simulation conditions may require mannequins to have different limb features or combinations. Because existing mannequins are mostly single, integrated structures, when training needs change, it is necessary to prepare multiple styles and specifications of mannequins to meet the requirements. This not only requires more investment in purchasing different mannequins, but also brings many inconveniences in storage and transportation, greatly reducing the convenience and efficiency of the training process. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a portable, modular mannequin, which solves the problem of the limited range of possibilities in existing mannequins.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a portable assembly mannequin, comprising two hand modules, two forearm modules, two upper arm modules, a head module, a chest module, two thigh modules, two lower leg modules, and two foot modules. The chest module and the head module, upper arm module, and thigh module are connected, as are the forearm module and the hand module and upper arm module, and the lower leg module and the thigh module and foot module, through an assembly mechanism. The assembly mechanism includes a connecting shell and two connecting plates, with a ball head fixedly provided at the center of one of the opposite ends of each of the two connecting plates.

[0006] Preferably, two fixing rods are fixedly installed on both sides of the inner wall of the front end of the connecting shell, and bearings are fixedly installed at the rear ends of the four fixing rods. Connecting columns are rotatably sleeved inside each pair of the four bearings.

[0007] Preferably, a semi-circular retaining plate is fixedly provided at the upper and lower ends of both connecting columns, and a reinforcing soft rubber is fixedly provided inside the semi-circular retaining plate. An adjusting gear is fixedly sleeved on the connecting column body located between the bearings, and a tension spring is fixedly provided at the center of the front inner wall of the connecting housing.

[0008] Preferably, a handle is fixedly provided at the front end of the tension spring, and a movable rod is fixedly provided at the center of the rear end of the handle. The rear end of the movable rod passes through the connecting shell and extends into the interior of the connecting shell, and a movable plate is fixedly provided thereon.

[0009] Preferably, racks are fixedly provided on both sides of the movable plate, an insertion hole is provided at the center of the rear end of the movable plate, an insertion rod is movably sleeved inside the rear end of the insertion hole, and a thrust spring is fixedly provided at the rear end of the movable plate.

[0010] Preferably, a connector is fixedly provided at the rear end of the insertion rod, the rear end of the connector is fixedly provided on the inner wall of the rear end of the connecting housing, the rear end of the thrust spring is movably sleeved on the insertion rod body, the rear end of the thrust spring is fixedly provided at the front end of the connector, and the gear and rack are meshed together.

[0011] Preferably, multiple connecting plates are fixedly installed at the connecting ends of two hand modules, two forearm modules, two upper arm modules, head module, chest module, two thigh modules, two lower leg modules, and two foot modules, with the ball head located inside between two semi-circular plates.

[0012] Working principle: In use, each part of this device is modularly designed, and each part is fixed with a connecting plate and ball head, which is a whole, while the structure related to the connecting shell is a separate whole. During assembly, pulling the handle outward stretches the tension spring, simultaneously moving the moving rod and moving plate, which in turn stretches the thrust spring. As the moving plate moves, the meshing of the rack and pinion drives the adjusting gear to rotate, which in turn rotates the connecting column. The rotation of the connecting column causes the semi-circular clamping plate to rotate to one side, unfolding the two semi-circular clamping plates away from each other. At this point, the ball head can be inserted into the interior of the semi-circular clamping plate. Then, releasing the handle, the moving plate returns to its original position under the combined action of the tension and thrust springs, firmly clamping the ball head inside the semi-circular clamping plate. The use of reinforced soft rubber to increase friction further enhances the clamping stability. This allows for easy disassembly, and the connecting joints can be adjusted and rotated at multiple angles. The bearing is used to fix the connecting column. The extended fixing rod makes it easy to fix the semi-circular clamping plate inside the connecting housing, increasing the overall stability.

[0013] This invention provides a portable, assembled mannequin. It has the following advantages: This invention provides a portable, modular mannequin. The mannequin employs a modular design, comprising multiple independent modules such as the head, chest, arms, and legs, which can be flexibly combined according to different training needs, avoiding the uniformity issues of traditional monolithic mannequins. Furthermore, the assembly mechanism, through the cooperation of ball joints and semi-circular clamping plates, combined with the linkage mechanism of tension springs, thrust springs, racks, and gears, achieves rapid assembly and disassembly of modules and multi-angle adjustment, ensuring stable connections and ease of operation. In addition, the introduction of reinforced soft rubber further enhances the clamping friction, improving the overall structural stability. This design not only reduces the procurement and storage costs of mannequins in medical training but also greatly facilitates handling and assembly, improving training efficiency. Overall, this invention, through modular and assembly technology, solves the problems of uniformity and inconvenience inherent in existing mannequins, providing a more flexible, efficient, and economical solution for medical training.

The assembly mechanism 1 includes a connecting shell 1015 and two connecting plates 1016, with a ball head 1017 fixedly provided at the center of one of the opposite ends of each of the two connecting plates 1016.

[0018] Two fixing rods 104 are fixedly installed on both sides of the inner wall of the front end of the connecting housing 1015. Bearings 105 are fixedly installed at the rear ends of the four fixing rods 104. Connecting columns 102 are rotatably sleeved inside each pair of the four bearings 105. Semicircular clamping plates 101 are fixedly installed at the upper and lower ends of the two connecting columns 102. Reinforcing soft rubber 1018 is fixedly installed inside the semicircular clamping plates 101. Adjusting gears 103 are fixedly sleeved on the column bodies of the connecting columns 102 located between the bearings 105. A tension spring 107 is fixedly installed at the center of the inner wall of the front side of the connecting housing 1015. A handle 106 is fixedly installed at the front end of the tension spring 107. A moving rod 108 is fixedly installed at the center of the rear end of the handle 106. The rear end of the moving rod 108 passes through the connecting housing 1015 and extends into the interior of the connecting housing 1015, and a moving plate 1010 is fixedly installed thereon. A rack 109 is fixedly installed on both sides of the movable plate 1010. An insertion hole 1011 is opened at the center of the rear end of the movable plate 1010. An insertion rod 1014 is movably fitted inside the rear end of the insertion hole 1011. A thrust spring 1012 is fixedly installed at the rear end of the movable plate 1010. A connector 1013 is fixedly installed at the rear end of the insertion rod 1014. The rear end of the connector 1013 is fixedly installed on the inner wall of the rear end of the connecting housing 1015. The rear end of the thrust spring 1012 is movably fitted onto the rod body of the insertion rod 1014. The rear end of the thrust spring 1012 is fixedly installed at the front end of the connector 1013. The gears and racks 109 are meshed together. Multiple connecting plates 1016 are fixedly installed at the connecting ends of two hand modules 4, two forearm modules 5, two upper arm modules 6, a head module 7, a chest module 8, two thigh modules 9, two lower leg modules 2, and two foot modules 3. A ball head 1017 is located inside between two semi-circular clamping plates 101.

[0019] Specifically, this invention features a modular design and the ability to flexibly adapt to different training needs. The mannequin consists of multiple independent modules, including a head module 7, a chest module 8, an upper arm module 6, a forearm module 5, a hand module 4, a thigh module 9, a lower leg module 2, and a foot module 3. These modules can be flexibly combined according to different training needs, such as injection, bandaging, and palpation. Traditional mannequins are mostly single, integral structures, which cannot meet diverse training requirements. The modular design of this invention avoids the problem of repeatedly purchasing multiple mannequins, reduces procurement and storage costs, and improves the flexibility and adaptability of training.

[0020] This invention enables quick assembly and disassembly as well as multi-angle adjustment. The assembly mechanism 1 is the core component of this invention for achieving modular connection. Through the cooperation of the ball head 1017 and the semi-circular clamping plate 101, it enables rapid connection and disassembly between modules. The semi-circular clamping plate 101 has a reinforced soft rubber 1018 inside to increase clamping friction and ensure connection stability. By adjusting the meshing of the gear 103 and rack 109, the connecting column 102 is rotated, realizing the opening and closing action of the semi-circular clamping plate 101, facilitating the insertion and fixing of the ball head 1017. When the handle 106 is pulled, the tension spring 107 and the push spring 1012 work together to move the moving plate 1010, completing the assembly or disassembly operation. After releasing the handle 106, the restoring force of the tension spring 107 and the push spring 1012 causes the semi-circular clamping plate 101 to automatically clamp the ball head 1017, ensuring the stability of the connection. Bearing 105 and fixing rod 104 are used to fix the connecting column 102. Fixing rod 104 is used to enhance the stability of the overall structure, ensuring that the assembled mannequin can withstand various operational training. The design of the assembly mechanism 1 makes the connection and disassembly between modules simple and quick, while the connecting joints can be adjusted at multiple angles to meet the needs of different training scenarios. This design not only improves the convenience of operation but also enhances the practicality of the mannequin.

[0021] The modules can be assembled or disassembled simply by pulling and releasing the handle 106. The operation is simple and intuitive, requiring no complex tools or techniques. The reinforced soft rubber 1018 and springs work together to ensure the stability of the connections between modules, preventing loosening or detachment during training. The modular design and multi-angle adjustment function allow the mannequin to simulate various medical procedures, such as injection, bandaging, and palpation, meeting diverse training needs. This invention significantly improves the efficiency of medical training, reduces training costs, and provides trainers with a more flexible and practical tool.
