Description

Technical Field

[0001] The invention relates to the technical field of childbirth teaching tools, in particular to a pre-delivery inspection and disinfection operation simulation device. Background Art

[0002] Traditional medical teaching cannot intuitively evaluate students' disinfection paths and inspection operations, especially during delivery simulation. Because the delivery process is dynamic, the elasticity of the birth canal will undergo corresponding elastic deformation as the baby progresses, and the deformation range is wide. For this reason, most existing delivery simulation models use replaceable vaginas for simulation, which require replacing the vaginal module according to different delivery states, resulting in inconsistent simulation. Moreover, most of their baby models use simple telescopic structures for delivery simulation, and the interaction between baby movement and birth canal changes is poor, resulting in poor simulation of delivery inspections and disinfection operations. Summary of the Invention

[0003] The purpose of the present invention is to overcome the above-mentioned shortcomings and provide a pre-delivery inspection and disinfection operation simulation device, which has the advantages of better and more consistent simulation effect, a large range of birth canal changes, and strong interactivity.

[0004] To achieve the above-mentioned purpose, the technical solution of the present invention is: a pre-delivery inspection and disinfection operation simulation device, including a pregnant woman component, a birth canal simulation component and a baby model. The birth canal simulation component includes a vulva component and an internal control component.

During delivery, as the movable ring moves, the range of the hemispherical limiting cavity surrounded by the elastic plate gradually increases.

[0005] Furthermore, rectangular connecting rods are provided on both sides of the elastic plate, and a limiting groove is provided on the movable ring for the rectangular connecting rod to be embedded in. The limiting groove includes an upward limiting portion and a rotation limiting portion. The rotation limiting portion is cylindrical and its side is a circle circumscribed to the side of the rectangular connecting rod. The upward limiting portion is located above the rotation limiting portion and can be embedded in the rectangular connecting rod. A sealing rod is provided on the top of the upward limiting portion, and a top rod corresponding to the limiting groove is provided at the bottom of the connecting ring. When the movable ring contacts the bottom of the connecting ring, the top rod abuts the rectangular connecting rod and moves from the upward limiting portion to the rotation limiting portion.

[0006] Furthermore, the simulation device also includes a magnetic cotton swab with a magnet inside. The vulva component has several linear Hall sensors along the vaginal matrix. The linear Hall sensors collect the path and area passed by the magnetic cotton swab and send signals to the computer.

[0007] Furthermore, the propulsion mechanism includes a main drive sleeve, the inner ring of which is arranged in parallel with several airbag rings, and a gas control component is connected between the several airbag rings. The gas control component is connected to an external air intake system to inflate the airbag rings. On the premise that the several airbag rings are filled with gas, the gas control component releases the gas in the airbag rings in sequence starting from the airbag ring on the side away from the vulva assembly and re-inflates them, so that different inflation saturations exist between the several airbag rings.

[0008] Furthermore, the gas control component is axially divided into an air inlet chamber and an air exhaust chamber, the air inlet chamber is connected to the air inlet duct, the air exhaust chamber is connected to the exhaust duct, and the head and tail sides of the airbag ring are respectively connected to the air inlet chamber and the exhaust chamber; wherein, the exhaust chamber is provided with a release switch at the corresponding position of each airbag ring, one end of the release switch is connected to the internal rotation of the air inlet chamber, and the other end of the release switch abuts against the air outlet of the airbag ring, and a reset wheel is provided below the air outlet of the airbag ring, and a telescopic rod assembly is provided on the top of the exhaust chamber, which hits the release switch at the top to make it leave the air outlet of the corresponding airbag ring, and at the same time, the release switch at the upper position transmits the release switch at the lower position to leave the air outlet of its corresponding airbag ring, and the other end of the release switch leaving the airbag ring outlet will contact the reset wheel, controlling the rotation of the reset wheel to reset the release switch.

[0009] Furthermore, the release switch in the upper position is provided with a transmission rod at the bottom, the transmission rod is inclined toward the other end of the release switch and one end of the transmission rod is located above the release switch in the lower position.

[0010] Furthermore, the propulsion mechanism also includes an auxiliary sleeve, one end of which is rotatably disposed in the main driving sleeve.

[0011] Furthermore, a fixed airbag is provided in the auxiliary sleeve, and the fixed airbag is connected to an external air intake system.

[0012] By adopting the above technical solution, the beneficial effects of the present invention are:

[0013] 1. The present invention simulates the opening size of the cervical os by providing multiple elastic plates. Before the movable ring contacts the connecting ring, the baby model moves and pushes the elastic plates under the action of the internal control component. At this time, the elastic plates use their own elasticity to cooperate with the abutment of the abutment parts to simulate the elasticity and opening size of the cervical os. The abutment plates move as the distance between the movable ring and the connecting ring changes, realizing the linkage between the baby model's delivery process and the elasticity of the birth canal, enhancing the simulation of the entire delivery process, and making the simulation process more coherent and realistic.

[0014] 2. The present invention realizes the connection between the elastic plate and the movable ring by setting a rectangular connecting rod. The different shapes of the upper limit groove on the movable ring at different displacements are matched to limit the movable mode of the elastic plate at different positions. When the entire movable ring is in contact with the connecting ring, the elastic plate increases the rotation function and the expansion of the birth canal reaches the maximum. Under the premise of ensuring that the birth canal conforms to the variation range, two birth canal diameter change methods are adopted to greatly extend the service life and elasticity of the entire model.

[0015] 3. The present invention uses a linear Hall sensor in conjunction with a cotton swab containing a magnetic block to collect the route and area of ​​the disinfection operation and send out corresponding signals, thereby realizing the collection of disinfection operations and making it more intuitive to determine whether students' operations are compliant.

[0016] 4. The present invention realizes the simulation of pushing the baby model in the birth canal by setting a main drive sleeve with multiple air bag rings built in. By controlling the air bag rings to perform repeated continuous inflation and deflation, it is more in line with the wave-like push suffered by the baby during the delivery process. Compared with the simple telescopic device movement drive, the present invention is more in line with the actual baby delivery state. The gas control component can be opened in conjunction to realize the sequential and continuous deflation and inflation operations of individual air bag rings. By setting a rotatable auxiliary sleeve, the simulation of the baby's rotation in the birth canal can be achieved by manual labor or the baby model's own weight, thereby enhancing the simulation effect of delivery.

[0047] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with specific embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention, but are not intended to limit the present invention.

[0048] Reference Figure 1-11 The present invention provides a technical solution: a pre-delivery inspection and disinfection operation simulation device. The device includes a pregnant woman component 1, a birth canal simulation component 2 and a baby model.

[0049] The pregnant woman component 1 and the baby model are both existing anthropomorphic models. Of course, the baby model can also be simply assembled from a simple spherical body and a rectangular body.

[0050] The birth canal simulation component 2 includes a vulva component 3 and an internal control component 4.

[0051] The vulva component 3 is arranged in the crotch of the maternity component 1. The vulva component 3 is made of high-quality silicone material, which makes it have a touch and elasticity similar to that of a real human body. At the same time, a vagina is left on the vulva component 3 for the baby model to pass through. In order to realize the information collection of the vulva disinfection operation, there are several linear Hall sensors 8 along the vaginal matrix of the vulva component 3. At this time, the simulation device also includes a magnetic cotton swab 7, which is provided with a magnet 71. The linear Hall sensor 8 collects the path and area passed by the magnetic cotton swab 7 and sends a signal to the computer. Specifically: when the magnetized cotton swab approaches the vulva component 3 for disinfection, the linear Hall sensor 8 will recognize the magnetism of the magnetized cotton swab. When multiple linear Hall sensors 8 are placed at a certain distance, the approach and distance movements of the cotton swab will be collected by the linear Hall sensor 8 and then transmitted to the computer for algorithm processing, so that the computer can realistically feedback the path and area passed by the disinfection cotton swab.

[0052] The internal control component 4 is arranged in the maternity component 1 and one end of it is connected to the vulva component 3. The internal control component 4 is a modular structure and can be detachably connected to the vulva component 3 by screws and nuts or magnetic attraction, and can be assembled as needed.

[0053] The internal control component 4 includes a cervical simulation mechanism 6 and a propulsion mechanism 5 .

[0054] The cervical simulation mechanism 6 includes a connecting ring 61, a movable ring 62, an elastic plate 63, a rotating rod 64 and an abutment 65. The connecting ring 61 is connected to the vulva component 3, and the connection method can be any detachable connection such as a bolt and nut or a magnetic connection. The movable ring 62 is movably arranged between the connecting ring 61 and the propulsion mechanism 5. The movable connection method can be to connect a long rod between the connecting ring 61 and the propulsion mechanism 5, so that the movable ring 62 passes through the long rod. If necessary, a spring is provided on the side of the long rod close to the connecting ring 61. Of course, a track for limiting can also be provided between the connecting ring 61 and the propulsion mechanism 5, so that the movable ring 62 can only move along the track direction. Several elastic plates 63 are arranged on the inner ring of the movable ring 62 and form a hemispherical limiting cavity on one side thereof. The elastic plate 63 has good elasticity, but in order to increase its deformation effect, it is necessary to set a deformation fulcrum on the side wall of the elastic plate 63. Therefore, the rotating rod 64 is located on one side of the elastic plate 63 and its two ends are respectively connected to the movable ring 62 and the connecting ring 61, and then one end of the abutment 65 is connected to the rotating shaft of the rotating rod 64, and the other end of the abutment 65 abuts against the side wall of the elastic plate 63. , so that the abutment ring acts on the side wall of the elastic plate 63 to limit its deformation. At the same time, the rotating rod 64 will fold during the movement of the movable ring 62, thereby driving the abutment ring away from the elastic plate 63. Therefore, during delivery, the baby model will press against the elastic plate 63 and move the movable ring 62. When the movement resistance of the movable ring 62 is greater than the movement force of the baby model, as the movable ring 62 moves, the range of the hemispherical limiting cavity surrounded above it will gradually increase.

[0055] In order to further increase the expansion range of the elastic plate 63 and increase the expansion mode of the elastic plate 63 in different states, rectangular connecting rods 631 are provided on both sides of the elastic plate 63, and a limiting groove 621 is provided on the movable ring 62 for the rectangular connecting rod 631 to be embedded. The limiting groove 621 includes an upward limiting portion 6211 and a rotation limiting portion 6212. The rotation limiting portion 6212 is cylindrical and its side surface is a circle circumscribed with the side surface of the rectangular connecting rod 631. The upward limiting portion 6211 is located above the rotation limiting portion 6212 and can be embedded in the rectangular connecting rod 631. A sealing rod 6213 is provided at the top of the upward limit portion 6211, and a top rod 6214 corresponding to the limit groove 621 is provided at the bottom of the connecting ring 61. When the movable ring 62 contacts the bottom of the connecting ring 61, the top rod 6214 abuts the rectangular connecting rod 631 and moves from the upward limit portion 6211 to the rotation limit portion 6212. At this time, the elastic plate 63 increases the rotation function. It should be noted that although the elastic plate 63 can rotate on the movable ring 62, due to the limitation of the connecting ring 61, the angle between the elastic plate 63 and the movable ring 62 after rotation will not exceed 90°.

[0056] The propulsion mechanism 5 is used to position the infant model and drive it toward the cervix simulation mechanism 6. Specifically, the propulsion mechanism 5 includes a main drive sleeve 51, the inner ring of which is arranged in parallel with a plurality of airbag rings 511. Gas control components 512 are connected between the airbag rings 511. The gas control components 512 are connected to an external air intake system to inflate the airbag rings 511. On the premise that the airbag ring 511 is filled with gas, the gas control component 512 releases the gas in the airbag ring 511 and re-inflates it in sequence starting from the airbag ring 511 on the side away from the vulva component 3, so that there are different inflation saturations among the airbag rings 511. In order to simulate the peristalsis in the birth canal, part of the gas in the airbag ring 511 is released and then the release is stopped and re-filled. This operation will be repeated, and there will be a delay in the operation of adjacent states. Specifically: the gas control component 512 is divided into an air intake chamber 121 and an exhaust chamber 122 along the axial direction. The air intake chamber 121 is connected to the air intake pipe, and the exhaust chamber 122 is connected to the exhaust pipe. The head and tail sides of the airbag ring 511 are respectively connected to the air intake chamber 121 and the exhaust chamber 122, and the air intake pipe and the exhaust pipe are both connected to the external system through the side wall of the main drive sleeve 51. Among them, the exhaust chamber 122 is provided with a release switch 123 at the corresponding position of each airbag ring 511, one end of the release switch 123 is connected to the internal rotation of the air inlet chamber 121, and a reset spring is coaxially arranged on the end when necessary; the other end of the release switch 123 is in contact with the air outlet of the airbag ring 511, and in order to increase the sealing effect, the surface of the other end can be covered with a rubber layer, and a reset wheel 124 is provided below the air outlet of the airbag ring 511, and the reset wheel 124 needs to be separately connected to a miniature rotating motor, and a telescopic rod assembly 125 is provided on the top of the exhaust chamber 122, and the telescopic rod assembly 125 intermittently performs telescopic movement, and the telescopic rod assembly 125 intermittently hits the release spring at the top. Switch 123 and make it leave the air outlet of the corresponding airbag ring 511. At this time, the release switch 123 in the upper position is transmitted to the release switch 123 in the lower position to make it leave the air outlet of its corresponding airbag ring 511, completing the linkage of air release. The other end of the release switch 123 leaving the air outlet of the airbag ring 511 will contact the reset wheel 124, and the reset wheel 124 is controlled to rotate to reset the release switch 123. In order to further realize the linkage of adjacent release switches 123, the release switch 123 in the upper position is provided with a transmission rod 126 at the bottom. The transmission rod 126 is inclined toward the other end of the release switch 123 and one end thereof is located above the release switch 123 in the lower position.

[0057] To enhance the simulation of the baby manikin's rotation within the birth canal, the propulsion mechanism 5 also includes an auxiliary sleeve 52, one end of which is rotatably mounted within the main drive sleeve 51. A fixed airbag 521 is housed within the auxiliary sleeve 52. This airbag 521 is connected to an external air intake system, controlling its inflation state to partially secure the baby manikin. The fixed airbag 521 primarily serves to stabilize the baby manikin's rotational simulation, and therefore, its securing strength is less than that of the airbag ring 511.
