Description

Technical Field

[0001] The present invention relates to the technical field of childbirth teaching aids, and particularly relates to a simulation device for pre-delivery examination and disinfection operations. Background Art

[0002] Traditional medical teaching cannot visually evaluate the disinfection path and examination operations of students. Especially during the childbirth simulation process, since the childbirth 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 of the existing childbirth simulation models use a replaceable vagina for simulation, which requires replacing the vagina module according to different childbirth states, resulting in discontinuous simulation. Moreover, most of its baby models use a simple telescopic structure for the birth simulation, and the interaction between the movement of the baby and the change of the birth canal is poor, resulting in poor simulation of childbirth examination and disinfection operations. Summary of the Invention

[0003] The purpose of the present invention is to overcome the above deficiencies and provide a simulation device for pre-delivery examination and disinfection operations, which has the advantages of better and more coherent simulation effects, a large range of birth canal changes, and strong interactivity.

[0004] To achieve the above purpose, the technical solution of the present invention is: A simulation device for pre-delivery examination and disinfection operations, comprising a pregnant woman component, a birth canal simulation component, and a baby model. The birth canal simulation component includes an external genitalia component and an internal control component. The external genitalia component is arranged at the crotch of the pregnant woman component, and the internal control component is arranged inside the pregnant woman component and one end of it is connected to the external genitalia component. Among them, the internal control component includes a propulsion mechanism and a cervix simulation mechanism. The propulsion mechanism is used to place the baby model and drive it to move towards the cervix simulation mechanism. The cervix simulation mechanism includes a connecting ring, a movable ring, an elastic plate, a rotating rod, and an abutting member. The connecting ring is connected to the external genitalia component. The movable ring is movably arranged between the connecting ring and the propulsion mechanism. A plurality of elastic plates are arranged in a ring shape on the inner circle of the movable ring and form a hemispherical limiting cavity on one side. The rotating rod is located on one side of the elastic plate and its two ends are respectively connected to the movable ring and the connecting ring. One end of the abutting member is connected to the rotation axis of the rotating rod, and the other end of the abutting member abuts against the side wall of the elastic plate, which is used to limit the deformation of the elastic plate. During childbirth, as the movable ring moves, the range of the hemispherical limiting cavity surrounded by the elastic plates gradually increases.

[0005] Further, rectangular connecting rods are provided on both sides of the elastic plate. A limiting groove for embedding the rectangular connecting rods is provided on the movable ring. The limiting groove includes an upward movement limiting portion and a rotation limiting portion. The rotation limiting portion is cylindrical and its side surface is a circle circumscribing the side surface of the rectangular connecting rod. The upward movement limiting portion is located above the rotation limiting portion and can accommodate the rectangular connecting rod for embedding. A sealing rod is provided at the top of the upward movement limiting portion. 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 against the rectangular connecting rod to move it from the upward movement limiting portion to the rotation limiting portion.

[0006] Further, the simulation device further includes a magnetic cotton swab. A magnet is provided inside the magnetic cotton swab. There are several linear Hall sensors along the vaginal matrix of the vulva assembly. The linear Hall sensors collect the path and area through which the magnetic cotton swab passes and send signals to a computer.

[0007] Further, the propulsion mechanism includes a main drive sleeve. A number of airbag rings are arranged in parallel in the inner circle of the main drive sleeve. A gas control member is connected between the number of airbag rings. The gas control member is connected to an external intake system to inflate the airbag rings. On the premise that the number of airbag rings are already filled with gas, the gas control member starts to release the gas in the airbag rings from the airbag ring on the side far from the vulva assembly and re-inflates them in turn, so that there are different inflation saturations between the number of airbag rings.

[0008] Further, the gas control member is axially divided into an intake chamber and an exhaust chamber. The intake chamber is connected to an intake pipeline, and the exhaust chamber is connected to an exhaust pipeline. The head and tail sides of the airbag ring are respectively connected to the intake chamber and the exhaust chamber; wherein, a release switch is provided at each corresponding position of the exhaust chamber and the airbag ring. One end of the release switch is rotatably connected to the inside of the intake chamber, and the other end of the release switch abuts against the air outlet of the airbag ring. A reset wheel is provided below the air outlet of the airbag ring. A telescopic rod assembly is provided at the top of the exhaust chamber. The telescopic rod assembly strikes the release switch at the topmost position to make it leave the air outlet of the corresponding airbag ring. At the same time, the release switch at the upper position drives the release switch at the lower position to leave the air outlet of its corresponding airbag ring. The other end of the release switch that leaves the air outlet of the airbag ring will contact the reset wheel, controlling the rotation of the reset wheel to reset the release switch.

[0009] Further, the release switch at the upper position is provided with a transmission rod at the bottom. The transmission rod is inclined towards the other end of the release switch and one end of it is located above the release switch at the lower position.

[0010] Further, the propulsion mechanism further includes an auxiliary sleeve. One end of the auxiliary sleeve is rotatably arranged inside the main drive sleeve.

[0011] Further, a fixed airbag is provided inside the auxiliary sleeve. The fixed airbag is connected to an external intake system.

[0012] By adopting the above technical solution, the beneficial effects of the present invention are as follows: 1. In the present invention, multiple elastic plates are provided to simulate the opening size of the cervix. Before the movable ring touches the connecting ring, the baby model moves under the action of the internal control component to push the elastic plate. At this time, the elastic plate uses its own elasticity and the abutment of the abutting member to simulate the elasticity and opening size of the cervix. The abutting plate displaces as the distance between the movable ring and the connecting ring changes, realizing the linkage between the output process of the baby model and the elasticity of the birth canal, enhancing the simulation of the entire childbirth process, and making the simulation process more coherent and realistic.

[0013] 2. In the present invention, a rectangular connecting rod is provided to connect the elastic plate and the movable ring. Combining with the different shapes of the limiting grooves on the movable ring at different displacements, the movable modes of the elastic plate at different positions are restricted. When the entire movable ring touches the connecting ring, the elastic plate increases the rotation function, and the expansion of the birth canal reaches the maximum. On the premise of ensuring that the birth canal conforms to the change range, two ways of changing the diameter of the birth canal are adopted, greatly extending the service life and elasticity of the entire model.

[0014] 3. The present invention uses a linear Hall sensor and a cotton swab containing a magnetic block to collect the route and area of the disinfection operation and send corresponding signals, realizing the collection of the disinfection operation, making it more intuitive whether the student's operation is compliant.

[0015] 4. In the present invention, a main driving sleeve with multiple airbag rings inside is provided to simulate the pushing of the baby model in the birth canal. By controlling the airbag rings to inflate and deflate repeatedly and continuously, it is more in line with the wave-like pushing suffered by the baby during childbirth. Compared with the simple telescopic device for moving and driving, the present invention is more in line with the actual state of the baby's birth. Combining with the gas control component that can be linked to open, the sequential and coherent operation of deflating and inflating each airbag ring one by one can be realized; by providing an auxiliary sleeve that can rotate, the simulation of the baby's rotation in the birth canal can be realized through manual or the self-weight of the baby model, increasing the simulation effect of childbirth.

Specific embodiments

[0024] In order to make the objectives, technical solutions and advantages of the present invention clearer and more understandable, the present invention will be 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 not to limit the present invention.

[0025] Referring to Figures 1-11 , the present invention provides a technical solution: a simulation device for pre - delivery examination and disinfection operations. The device includes a pregnant woman component 1, a birth canal simulation component 2 and a baby model.

[0026] Both the pregnant woman component 1 and the baby model are existing anthropomorphic models. Of course, the baby model can also be simply assembled from a simple spherical body and a rectangular body.

[0027] The birth canal simulation component 2 includes an external genitalia component 3 and an internal control component 4.

[0028] The external genitalia component 3 is arranged at the crotch of the pregnant woman component 1. The external genitalia component 3 is made of high - quality silicone material, so that it has a touch and elasticity similar to that of a real human body. At the same time, a vagina for the baby model to pass through is left on the external genitalia component 3. To collect information on the disinfection operation of the external genitalia, several linear Hall sensors 8 are arranged along the vagina matrix on the external genitalia component 3. At this time, the simulation device also includes a magnetic cotton swab 7. A magnet 71 is arranged inside the magnetic cotton swab 7. 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 external genitalia component 3 for disinfection operation, 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 approaching and leaving actions 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 path and area passed by the disinfection cotton swab can be realistically reflected on the computer.

[0029] The internal control component 4 is disposed within the pregnant woman component 1 and one end thereof is connected to the vulva component 3. The internal control component 4 is of a modular structure and can be detachably connected to the vulva component 3 by means of screws and nuts or magnetic attraction, and can be assembled as required.

[0030] The internal control component 4 includes a cervical simulation mechanism 6 and a propulsion mechanism 5.

[0031] The cervical simulation mechanism 6 includes a connecting ring 61, a movable ring 62, an elastic plate 63, a rotating rod 64 and an abutting member 65. The connecting ring 61 is connected to the vulva component 3, and the connection method can be any detachable connection such as bolt and nut or magnetic connection. The movable ring 62 is movably disposed between the connecting ring 61 and the propulsion mechanism 5. The movable connection method can be that a long rod is connected between the connecting ring 61 and the propulsion mechanism 5, and the movable ring 62 is passed through the long rod. When necessary, a spring is provided on the side of the long rod close to the connecting ring 61. Of course, a limiting track can also be provided between the connecting ring 61 and the propulsion mechanism 5 to make the movable ring 62 can only move along the track direction. A plurality of elastic plates 63 are annularly arranged on the inner circle 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, a deformation fulcrum needs to be provided 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 abutting member 65 is connected to the rotation axis of the rotating rod 64, and the other end of the abutting member 65 abuts against the side wall of the elastic plate 63, so that the abutting ring acts on the side wall of the elastic plate 63 to limit its deformation. At the same time, the rotating rod 64 will be folded during the movement of the movable ring 62 and then drive the abutting ring away from the elastic plate 63. Therefore, during childbirth, the baby model will push against the elastic plate 63 and then cause the movement of 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.

[0032] To further increase the expansion range of the elastic plate 63 and diversify the expansion modes 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 for the rectangular connecting rods 631 to be inserted into is provided on the movable ring 62. The limiting groove 621 includes an upward movement limiting portion 6211 and a rotation limiting portion 6212. The rotation limiting portion 6212 is cylindrical and its side surface is a circle circumscribing the side surface of the rectangular connecting rod 631. The upward movement limiting portion 6211 is located above the rotation limiting portion 6212 and the rectangular connecting rod 631 can be inserted into it. A sealing rod 6213 is provided at the top of the upward movement limiting portion 6211, and a top rod 6214 corresponding to the limiting 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 against the rectangular connecting rod 631 and moves it from the upward movement limiting portion 6211 to the rotation limiting portion 6212. At this time, the elastic plate 63 gains a 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°.

[0033] The propulsion mechanism 5 is used to place the baby model and drive it to move towards the cervical simulation mechanism 6. Specifically: The propulsion mechanism 5 includes a main drive sleeve 51. Inside the inner circle of the main drive sleeve 51, a number of airbag rings 511 are arranged in parallel. A gas control member 512 is connected between the number of airbag rings 511. The gas control member 512 is connected to an external intake system to inflate the airbag rings 511. On the premise that the airbag rings 511 are already filled with gas, the gas control member 512 starts to release the gas in the airbag rings 511 and re-inflate them in sequence from the airbag rings 511 on the side away from the vulva assembly 3, so that there are different inflation saturations between the number of airbag rings 511. To simulate the peristalsis in the birth canal, the operation of releasing part of the gas in the airbag rings 511 and then stopping the release and re-filling will be repeated all the time, and there will be a delay between adjacent states of operation. Specifically: The gas control member 512 is axially divided into an intake chamber 121 and an exhaust chamber 122. The intake chamber 121 is connected to the intake pipeline, and the exhaust chamber 122 is connected to the exhaust pipeline. The head and tail sides of the airbag rings 511 are respectively connected to the intake chamber 121 and the exhaust chamber 122. Both the intake pipeline and the exhaust pipeline are connected to the external system through the side wall of the main drive sleeve 51. Among them, a release switch 123 is provided at the corresponding position of the exhaust chamber 122 for each airbag ring 511. One end of the release switch 123 is rotatably connected to the inside of the intake chamber 121, and a return spring is coaxially arranged at the end if necessary; the other end of the release switch 123 abuts against the air outlet of the airbag ring 511. To increase the sealing effect, a rubber layer can be made to cover the surface of the other end. A return wheel 124 is provided below the air outlet of the airbag ring 511. The return wheel 124 needs to be separately connected to a miniature rotary motor. A telescopic rod assembly 125 is provided at the top of the exhaust chamber 122. The telescopic rod assembly 125 intermittently performs telescopic movements. The telescopic rod assembly 125 intermittently strikes the release switch 123 at the topmost position and makes it leave the air outlet of the corresponding airbag ring 511. At this time, the release switch 123 in the upper position drives 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 that leaves the air outlet of the airbag ring 511 will contact the return wheel 124, controlling the rotation of the return wheel 124 to realize the reset of the release switch 123. In order to further realize the linkage of adjacent release switches 123, a transmission rod 126 is provided at the bottom of the release switch 123 in the upper position. The transmission rod 126 is inclined towards the other end of the release switch 123 and one end of it is located above the release switch 123 in the lower position.

[0034] In order to increase the rotatable simulation of the infant model in the birth canal, the propulsion mechanism 5 further includes an auxiliary sleeve 52, and one end of the auxiliary sleeve 52 is rotatably arranged in the main drive sleeve 51. A fixed airbag 521 is arranged in the auxiliary sleeve 52. The fixed airbag 521 is connected to an external air intake system, and the inflation state of the fixed airbag 521 is controlled to achieve partial fixation of the infant model. The fixed airbag 521 is mainly used to meet the rotational simulation fixation of the infant model. Therefore, its fixation strength is less than that of the airbag ring 511.
