[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] Embodiment 1

[0034] See also Figures 1 to 11 The present invention provides a technical solution: an anesthesia operation simulation device, comprising: a bracket 11, a model seat 12 is set on the top of the bracket 11, a simulated finger 13 is set on the end surface of the model seat 12, a nail model 14 is fixed on the surface of the simulated finger 13, and the simulated finger 13 is made of high elastic rubber material;

[0035] The invention also includes: an injection assembly 2 and an observation assembly 5, wherein the injection assembly 2 is arranged on the inner wall of the model seat 12, the observation assembly 5 is connected to the injection assembly 2, the injected simulation liquid is stored through the injection assembly 2, and the injection amount of the simulation liquid is monitored through the observation assembly 5;

[0036] An adjusting component 3, which is disposed inside the model seat 12, and through which the expansion diameter of the simulated finger 13 is adjusted;

[0037] The inflatable component 6 and the control component 7, the inflatable component 6 is connected to the adjustment component 3, the control component 7 is connected to the inflatable component 6, the control component 7 drives the inflatable component 6 to operate, and the adjustment component 3 is inflated and exhausted through the inflatable component 6 to assist in adjusting the diameter of the simulated finger 13.

[0038] The injection assembly 2 includes an insert tube 21 fixed inside the simulated finger 13, and an insert cavity 22 is opened inside the insert tube 21, a connecting tube 23 is fixed to the end face of the insert tube 21, and a tube cavity 24 is opened inside the connecting tube 23. When the anesthetic needle tip passes through the insert tube 21 and is inserted into the inside of the insert cavity 22, the piston rod inside the anesthetic syringe is pushed to simulate the injection of anesthetic liquid into the inside of the insert cavity 22, and the anesthetic liquid enters the inside of the tube cavity 24 through the insert cavity 22. The support plate 24 is pressed against the surface of the connecting tube 23. By adjusting the squeezing area of ​​the supporting plate 24 on the connecting tube 23, the storage space inside the tube cavity 24 is adjusted. The size of the storage space of the tube cavity 24 is adjusted synchronously according to demand, which is beneficial to the anesthesia simulation training of the practitioners and improves the training effect.

[0039] The adjusting assembly 3 includes a supporting plate 131 pressed against the inner wall of the simulated finger 13, and the side of the supporting plate 131 is rotatably connected to the rotating plate 33 through a movable shaft 132, and the end of the rotating plate 33 away from the supporting plate 131 is rotatably connected to the airbag tube 35 through a movable shaft 234, and a connecting rod 36 is fixed to the end surface of the airbag tube 35, and the end surface of the connecting rod 36 is fixed to the inner wall of the simulated finger 13. When it is necessary to increase the diameter of the simulated finger 13, the airbag tube 35 is first inflated, and the airbag tube 35 expands outward after being inflated. The airbag tube 35 pushes the rotating plate 33 to move outward through the movable shaft 234, and after the rotating plate 33 moves in the direction away from the airbag tube 35, the two groups of rotating plates 33 are unfolded, and the rotating plate 33 is rotated in the movable shaft 234. With the cooperation of the moving shaft 32, the support plate 31 is pushed to move in the direction away from the airbag tube 35, and the support plate 31 pushes the simulated finger 13 to expand outward, thereby increasing the diameter of the simulated finger 13. When the diameter of the simulated finger 13 needs to be reduced, the gas inside the airbag tube 35 is extracted, and the airbag tube 35 shrinks after being deflated, thereby indirectly driving the two groups of rotating plates 33 to approach each other and cover each other, and the support plate 31 moves in the direction close to the airbag tube 35, and the supporting force of the support plate 31 on the simulated finger 13 is reduced, and the simulated finger 13 shrinks, thereby reducing the diameter of the simulated finger 13. According to the training requirements, the diameter of the simulated finger 13 is randomly adjusted to achieve training of multiple diameters and improve the training effect.

[0040] A support plate 24 is fixed on the surface of the rotating plate 33, and the support plate 24 is pressed against the surface of the connecting tube 1 23. In the process of increasing the diameter of the simulated finger 13, the two sets of rotating plates 33 are unfolded with each other, and the rotating plate 33 drives the support plate 24 to move synchronously. After the support plate 24 moves with the rotating plate 33, the contact area between the support plate 24 and the connecting tube 1 23 gradually decreases, and the pressing force of the support plate 24 on the connecting tube 1 23 gradually decreases, and the extrusion force on the connecting tube 1 23 decreases. The connecting tube 1 23 is gradually unfolded, and the storage space of the connecting tube 1 23 is increased, and the synchronous adjustment is performed. The storage space of the connecting tube 23 is related to the diameter of the simulated finger 13. The larger the diameter of the simulated finger 13 is, the larger the dosage of the simulated liquid that needs to be injected into the connecting tube 23 is. In the process of reducing the diameter of the simulated finger 13, the two sets of rotating plates 33 approach each other, and the rotating plates 33 drive the supporting plates 24 to gradually press against the connecting tube 23. The supporting plates 24 squeeze the connecting tube 23, and the internal space of the connecting tube 23 is reduced, thereby reducing the storage space of the simulated liquid. The practitioner determines the injection dosage of the simulated liquid according to the diameter of the simulated finger 13, thereby realizing random training of multiple groups of size grades.

[0041] The observation assembly 5 includes a cannula 51 fixed on the end face of the connecting tube 23, a cannula 52 is inserted inside the cannula 51, and a connecting tube 53 is fixed to the end face of the cannula 52, and an observation box 54 is fixed to the end of the connecting tube 53 away from the cannula 51. The simulated liquid injected into the insert tube 21 enters the interior of the lumen 24, and the simulated liquid enters the interior of the connecting tube 53 through the cannula 51 and the cannula 52, and then enters the interior of the observation box 54. The simulated liquid entering the observation box 54 is observed to judge the dosage of the liquid injected by the practitioner, thereby indirectly evaluating the effect of the anesthesia simulation of the practitioner.

[0042] A transparent plate 55 is fixed to the surface of the observation box 54, and a rubber plate 56 is inserted into the side of the observation box 54. With the help of the transparent plate 55, it is convenient to observe the simulated liquid inside the observation box 54 through the transparent plate 55. During the process of removing the simulated liquid, the rubber plate 56 is pulled away from the observation box 54, and the rubber plate 56 is moved out from the inside of the observation box 54 after elastic deformation. The simulated finger 13 is turned upside down. Under the action of gravity, the simulated liquid inside the lumen 24 is moved out through the connecting tube 2 53 and the observation box 54, thereby realizing the removal operation of the simulated liquid, which is convenient for reuse.

[0043] Embodiment 2

[0044] The inflation component 6 includes a connection port 1 61 fixed on the end face of the airbag tube 35, and the end face of the connection port 1 61 is connected to the connection port 2 63 through a connection tube 3 62, and the connection port 2 63 is fixed on the surface of a connection tube 64, and a piston plate 65 is inserted inside the connection tube 64. The airbag tube 35 is inflated or evacuated through the connection tube 64 and the piston plate 65, thereby promoting the unfolding and folding operation of the rotating plate 33, realizing the adjustment of the diameter of the simulated finger 13, randomly adjusting the diameter of the simulated finger 13 and the storage space of the connection tube 1 23, and realizing anesthesia training operations of multiple size gears.

[0045] The control assembly 7 includes a screw 71 rotatably connected to the surface of the piston plate 65, and the outer wall of the screw 71 is threadedly connected to a screw sleeve 72, the outer wall of the screw sleeve 72 is fixed with a gear 1 73, and the top of the gear 1 73 is mounted with a gear 2 74. The rotation of gear 2 74 can drive the gear 1 73 to rotate synchronously. The rotation of gear 1 73 drives the screw 71 to move through the screw sleeve 72, and the movement of the screw 71 drives the piston plate 65 to move synchronously, thereby controlling the lateral movement of the piston plate 65, promoting the movement of the gas inside the connecting tube 64, and realizing the gas exchange operation, thereby facilitating the inflation and degassing operations of the airbag tube 35.

[0046] The interior of the model seat 12 is provided with a connecting cavity 76 which cooperates with gear 2 74. The outer wall of gear 2 74 is rotatably connected to a connecting seat 75 via a rotating shaft. A spring 77 is fixed to the bottom of the connecting seat 75, and the bottom of the spring 77 is fixed to the inner wall of the connecting cavity 76. Pressing gear 2 74 downward realizes the meshing operation of gear 1 73 and gear 1 73. Under the action of spring 77, gear 2 74 is pushed to separate gear 1 73 from gear 2 74. During use, if gear 2 74 is accidentally touched, the rotation of gear 2 74 will not drive gear 1 73 to rotate, thereby avoiding accidental touching and realizing the protection operation of gear 2 74.

[0047] In the process of inflating the airbag tube 35, firstly, the gear 2 74 is pressed downward, and the gear 2 74 drives the connecting seat 75 to move downward synchronously, and the connecting seat 75 squeezes the spring 77. After being squeezed, the spring 77 is in a compressed and force-storing state, and the gear 2 74 moves downward and meshes with the gear 1 73. After the gear 2 74 meshes with the gear 1 73, the fingertips push the gear 2 74 to rotate, and the rotation of the gear 2 74 drives the gear 1 73 to rotate synchronously, and the rotation of the gear 1 73 drives the screw sleeve 72 to rotate synchronously. With the cooperation of the inner wall thread of the screw sleeve 72, the rotation of the screw sleeve 72 drives the screw rod 71 to move, and the screw rod 71 drives The piston plate 65 moves synchronously, and the piston plate 65 moves in the direction close to the airbag tube 35. The piston plate 65 pushes the gas inside the connecting tube 64. The gas inside the connecting tube 64 enters the interior of the airbag tube 35 through the connecting port 2 63, the connecting tube 3 62 and the connecting port 1 61 to inflate the airbag tube 35. After the airbag tube 35 is inflated, it indirectly pushes the rotating plate 33 to move, thereby realizing the diameter adjustment operation of the simulated finger 13. After the adjustment is completed, the pressure on the gear 2 74 is released. Under the push of the spring 77, the spring 77 pushes the gear 2 74 to return to its initial position through the connecting seat 75.

[0048] When it is necessary to extract the air inside the airbag tube 35, after pressing down on gear two 74, rotate gear two 74 in the reverse direction, indirectly realizing the reverse movement of screw rod 71, screw rod 71 drives piston plate 65 to move away from airbag tube 35, connecting tube 64 extracts the gas inside the airbag tube 35 through connecting tube three 62, realizing the air extraction operation of airbag tube 35, thereby indirectly reducing the diameter of simulated finger 13.

[0049] An insertion rod 81 is inserted inside the screw 71, and a support rod 82 is fixed to the end face of the insertion rod 81. Both ends of the support rod 82 are fixed to the inner wall of the model base 12. The screw 71 is limited by the insertion rod 81 to prevent the screw 71 from rotating synchronously with the screw sleeve 72, so that the rotation of the screw sleeve 72 can drive the screw 71 to move, making the movement of the screw 71 more stable, thereby improving the stability of the movement of the screw 71.
