[0036] in accordance with Figures 1 to 4 :
[0037] This application provides a newborn model, including: an infant model body, an umbilical cord model 3, and a urinary catheterization module 4;
[0038] Preferably, the infant model body includes: a simulated head and neck 1, a simulated torso 2, and simulated limbs;
[0039] Further, preferably, the simulated head 1 includes: a simulated skull 16 conforming to the anatomical structure of the human body, a simulated nasal cavity 11, an oral cavity 13, a tongue 14, a trachea 12, an esophagus 15; and a first neck connection 17.
[0040] Further, preferably, the simulated torso 2 includes: a simulated thorax 21, a simulated sternum 22, a pressing module 5, and an embedded plate 6;
[0041] The simulated sternum 22 is embedded in the simulated thorax 21;
[0042] The pressing module 5 is located in the middle of the embedded plate 6;
[0043] The umbilical cord model 3 is placed on the side of the embedded plate 6 near the catheterization module 4;
[0044] The embedded plate 6 is provided with a second neck connection part 61 on the side near the simulated head and neck 1;
[0045] The first neck connector 17 is connected to the second neck connector 61 via a universal joint 7;
[0046] The simulated thoracic cage 21 constitutes a simulated thoracic cavity; the pressing module 5 and the umbilical cord model 3, except for the simulated umbilical cord 33, are all located inside the simulated thoracic cavity;
[0047] Preferably, air sacs 122 are provided on the simulated thoracic cage 21 near the anatomical position of the lungs, and the trachea 12 is connected to the air passage of the air sacs 122 through the air sac connector 121.
[0048] When performing artificial respiration, the air bag 122 inflates; when performing endotracheal intubation, the air bag 122 is pushed up by the intubation tube, indicating that the insertion is correct.
[0049] The pressing module 5 includes: a slide cylinder 53, a piston 54, a spring 55, and a base 56;
[0050] The slide cylinder 53 is provided with a first air hole 51 at one end near the embedded plate 6; the slide cylinder 53 is provided with a second air hole 52 at one end near the simulated sternum 22.
[0051] Wherein, one end of the vertical portion of the piston 54 is fixed together with the simulated sternum 22; the horizontal portion of the piston 54 is sealed inside the slide cylinder 53; the diameter of the second air hole 52 is smaller than the thickness of the horizontal portion of the piston 54;
[0052] The spring 55 is disposed between the piston 54 and the base 56 to provide resistance when pressed;
[0053] In use, the initial position of the horizontal part of the piston 54 is the position that blocks the second vent 52; when pressed, the horizontal part of the piston 54 begins to move towards the base 56, and the gas in the cylinder 53 is discharged into the air through the first vent 51; when the pressing stops, the spring 55 returns to its original shape, causing the horizontal part of the piston 54 to move away from the base 56, and the gas is drawn into the cylinder 53 from the first vent 51. At the same time, the gas near the second vent 52 is discharged from the cylinder 53 from the second vent 52 until the horizontal part of the piston 54 reaches its initial position.
[0054] Preferably, the umbilical cord model 3 includes: a first base 31, a second base 32, and a simulated umbilical cord 33;
[0055] The first base 31 is provided with a pipe 34, and its bottom is provided with a drainage pipe connector 35 that is connected to the liquid passage of the pipe 34; the drainage pipe connector 35 is used to connect a drainage bag (not shown in the figure).
[0056] The first base 31 is provided with a first locking protrusion 311 near the middle;
[0057] The second base 32 is hollow and has a "T" shaped cross section. Its vertical part is inserted into the insertion hole 312 of the first base and is fixed in the insertion hole of the first base 31 by the second latching protrusion 321.
[0058] The second base 32 is provided with a second locking protrusion 321 on the surface in contact with the first base 31, which is used to increase the frictional force on the contact surface with the first base 31 and fix the relative position of the two.
[0059] One end of the simulated umbilical cord 33 is movably connected to the second base 32 via an umbilical cord connector 322.
[0060] The simulated umbilical cord 33 contains a simulated blood vessel 331, which is connected to the fluid path of the pipe 34.
[0061] During training, umbilical vein catheterization and umbilical artery catheterization are performed on the simulated blood vessel 331. During infusion, the drainage bag (not shown in the figure) is placed in a lower position, and the liquid is drained into the external drainage bag through the simulated blood vessel 331, the pipe 34, and the drainage tube connector 35.
[0062] During training, when performing a simulated umbilical cord 33 removal procedure, part of the simulated umbilical cord 33 is removed, and a drainage bag (not shown in the figure) is placed above the simulated umbilical cord 33. The fluid in the drainage bag flows out through the simulated blood vessel 331. At this time, ligation operation training can be performed.
[0063] When the simulated umbilical cord 33 is replaced, the second base 32 is exposed above the simulated skin 8. The umbilical cord connector 322 is pulled out from the second base 32, and a new simulated umbilical cord 33 is placed on the umbilical cord connector 322. The umbilical cord connector 322 is then reinserted into the second base 32. Since the simulated skin 8 is the skin of a newborn, it is relatively soft and prone to collapse. A first locking protrusion 311 is provided to prevent the simulated skin 8 from collapsing during the replacement of the simulated umbilical cord 33. At the same time, the second base 32 can be replaced promptly if there is a problem.
[0064] Preferably, the urinary catheterization module 4 includes: a duckbill valve 41, a urethra 42; and a drainage bag connection port 43 disposed at the rear of the urethra 42; wherein the duckbill valve 41 is disposed on the urethra 42.
[0065] When in use, insert the catheter into the genital area of the infant model. When it passes through the duckbill valve 41, urine flows out. The drainage bag is placed at a high position on the infant model to create a height difference that simulates the pressure inside the bladder. When the catheter is not inserted into the duckbill valve 41, the pressure difference can be used to prevent the liquid from being discharged from the body. The greater the pressure difference, the better the water retention effect.
[0066] The above embodiments are merely examples for clear illustration and are not intended to limit the implementation.
