Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of medical teaching models, in particular to a newborn umbilical cord care training model. Background Art
[0002] The umbilical cord is a tubular structure that connects the newborn and the placenta. It is a ribbon-like object, shaped like a rope, with a moist and smooth surface. There are two arteries and a vein in the umbilical cord, which constitute the umbilical blood vessels. After the birth of a newborn, quickly and accurately tying the umbilical cord of the newborn is a basic professional skill that obstetricians and gynecologists, midwives and nurses should have. In order to train qualified midwives in clinical practice, it is imperative to establish a model in the training room of a hospital or medical school so that students and intern nurses can master the basic skills of quickly and accurately tying the umbilical cord of a newborn.
[0003] At present, clinical and midwifery students can only listen to the teachers' explanations during the internship while in school or during internship. Students are generally not allowed to perform umbilical cord care directly because once the simulated umbilical cord is cut, it cannot be fixed on the newborn model and can only be replaced with a new simulated umbilical cord. This will increase the cost of training. In addition, the umbilical cord generally has a certain length. If it is cut, the umbilical cord that is not used temporarily cannot be stored, which will also affect subsequent operations. Summary of the invention

[0026] Reference Figure 1A newborn umbilical cord care training model includes an abdominal wall 1, an umbilical cord 2, a storage mechanism 3, and a placenta 4. The abdominal wall 1 is made of hard plastic material and can be installed on an adapted newborn model. The umbilical cord 2 is a soft tube and is arranged between the abdominal wall 1 and the placenta 4. The storage mechanism 3 is arranged between the umbilical cord 2 and the placenta 4 and is arranged close to the placenta 4 to store the umbilical cord 2 and other utensils. The umbilical cord 2 first passes through the abdominal wall 1, then passes through the storage mechanism 3, and is finally connected to the placenta 4. When in use, after the umbilical cord 2 is disconnected, the storage mechanism 3 is started to store the umbilical cord 2 that is no longer in use, thereby reducing the space occupied by the umbilical cord 2 that is no longer in use and affecting the operation. When the operation is completed, other utensils can also be stored.
[0027] Reference Figure 2 and Figure 3 , there is a hole 11 on the abdominal wall 1, and the hole 11 is used for the umbilical cord 2 to pass through. The umbilical cord 2 includes a covering tube 21, a simulated artery 22, and a simulated vein 23, and the simulated artery 22 and the simulated vein 23 are both arranged in the covering tube 21. There are two simulated arteries 22, and the two simulated arteries 22 and the simulated vein 23 are intertwined and arranged along the length direction of the covering tube 21, and the simulated arteries 22 and the simulated vein 23 are filled with simulated blood. The umbilical cord 2 is composed of multiple umbilical cord segments of uniform length, and every two adjacent umbilical cord segments are connected by threads. Refer to Figure 1 One end of the umbilical cord 2 along its length direction passes through the hole 11 , and the end of the umbilical cord 2 that passes through the hole 11 and is away from the storage mechanism 3 is threadedly connected with a first nut 24 .
[0028] When in use, one end of the umbilical cord 2 along its length direction is passed through the hole 11, and then the first nut 24 is tightened to complete the fixation of the umbilical cord 2 and the abdominal wall 1. Any two adjacent sections of the umbilical cord 2 can also be rotated in opposite directions to disassemble them for easy operation.
[0029] Reference Figure 1 and Figure 4 The storage mechanism 3 includes a storage box 31, a screw 32, a limit block 33, a rotating rod 34, and a slider 35. The storage box 31 is hollow inside, and the side walls of the storage box 31 at both ends along its length direction are provided with first limit holes 311 for the umbilical cord 2 to pass through. A drawer 36 is slidably connected to the bottom of the storage box 31, and the drawer 36 is hollow inside. The screw 32 is arranged along the width direction of the storage box 31 and is arranged at one end of the storage box 31 close to the abdominal wall 1. One end of the screw 32 along the length direction passes through the side wall of the storage box 31 and is rotatably connected thereto. The screw 32 is fixedly connected to a handle 321 at the end passing through the storage box 31, and the other end of the screw 32 is also rotatably connected to the side wall of the storage box 31. A second nut 322 is threadedly connected to the end of the screw 32 passing through the storage box 31, and the second nut 322 is used to fix the handle 321. Refer again Figure 5The limit block 33 is arranged in the storage box 31 and sleeved on the screw rod 32, and is threadedly connected with the screw rod 32. A limit groove 312 matching the limit block 33 is provided on the bottom surface of the storage box 31 below the screw rod 32, and the slide groove 313 is arranged parallel to the screw rod 32. A connection block 331 is fixed on the top of the limit block 33, and a second limit hole 3311 for the umbilical cord 2 to pass through is provided on the connection block 331.
[0030] Reference Figure 4 and Figure 6 , the rotating rod 34 is arranged in the storage box 31, and the rotating rod 34 is arranged parallel to the screw rod 32 and arranged on the side of the screw rod 32 close to the placenta 4. The rotating rod 34 is rotatably connected to the side wall of the storage box 31 at both ends along its length direction, and the rotating rod 34 is used to store the umbilical cord 2. The screw rod 32 is sleeved with a first pulley 323 at one end close to the handle 321, and the first pulley 323 is arranged in the storage box 31 and fixedly connected to the screw rod 32. The rotating rod 34 is sleeved with a second pulley 341 at one end close to the handle 321, and the second pulley 341 is arranged in the storage box 31 and fixedly connected to the rotating rod 34, and a belt 342 is connected to the first pulley 323 and the second pulley 341. A slide groove 313 adapted to the slider 35 is opened at the top of the storage box 31 at one end close to the placenta 4, and the slide groove 313 is arranged parallel to the screw rod 32. The slider 35 is disposed in the slide groove 313 and is slidably connected thereto, and a clip 351 is fixedly disposed on the bottom surface of the slider 35 , and the clip 351 is used to clamp and fix the umbilical cord 2 .
[0031] When in use, after cutting the umbilical cord 2, loosen the second nut 322, turn the handle 321, and drive the screw rod 32 to rotate. Since the limit block 33 is threadedly connected to the screw rod 32 and the limit groove 312 is limited, the limit block 33 can only move along the length direction of the screw rod 32, so that the umbilical cord 2 is more evenly wound on the rotating rod 34. At the same time, after the screw rod 32 rotates, the first pulley 323 rotates. Since the first pulley 323 and the second pulley 341 are connected by the belt 342, the second pulley 341 is driven to rotate, so that the rotating rod 34 rotates, and the umbilical cord 2 is wound on the rotating rod 34.
[0032] Reference Figure 1 The placenta 4 is made of soft plastic material. The umbilical cord 2 is connected to the placenta 4 at one end that passes through the storage box 31 and is away from the abdominal wall 1. A buckle is provided at the connection between the umbilical cord 2 and the placenta 4, and the buckle is used to fix the umbilical cord 2 and the placenta 4.
[0033] When not in use, the umbilical cord 2 passes through the abdominal wall 1, the first limiting hole 311 and the second limiting hole 3311 near the abdominal wall 1, and is wound around the rotating rod 34, then passes through the clip 351 and the first limiting hole 311 near the placenta 4, and is finally fixed to the placenta 4 by a buckle. During use, the two adjacent sections of the umbilical cord 2 are rotated, the umbilical cord 2 is disconnected, the second nut 322 is loosened, and the handle 321 is turned to drive the screw 32 and the first pulley 323 to rotate, thereby moving the limiting block 33, so that the umbilical cord 2 is evenly wound around the rotating rod 34. Since the first pulley 323 and the second pulley 341 are connected by the belt 342, the second pulley 341 will be driven to rotate, thereby rotating the rotating rod 34 to achieve the winding of the umbilical cord 2. After use, the umbilical cord 2 can be tightened, the first nut 24 can be unscrewed, the abdominal wall 1 can be removed, the buckle can be opened, the placenta 4 can be removed, and all the utensils can be placed in the drawer 36 for storage.
