Description

Technical Field

[0001] The utility model relates to the technical field of medical auxiliary appliances, in particular to a new teaching aid for training maternity specialist nurses. Background Art

[0002] Vaginal examination is a necessary examination method in obstetric clinical practice to understand the progress of labor, such as cervical dilatation and descent of the fetal presenting part. When a pregnant woman is in labor, the uterus contracts regularly, pulling the uterine muscles and surrounding fibers of the internal cervical os. In addition, the amniotic fluid sac in front of the fetal presenting part is wedge-shaped, causing the internal cervical os to expand upward and outward, and the cervical canal gradually shortens until it disappears. The external cervical os is usually only the size of a fingertip. As labor progresses, the external cervical os expands to a diameter of 10 cm, which can allow the full-term fetal head to pass through. This process is called cervical dilatation.

[0003] Cervical dilatation examination refers to touching the dilatation of the cervix with the index and middle fingers of sterile gloves through the vagina. It is the most basic obstetric technique and the basis for labor observation and delivery management. In the training of maternal and child nurses, the assessment of the cervix of pregnant women is a very important skill operation. The accuracy of the cervical judgment will directly affect the nurse's judgment on the progress of the labor process of pregnant women and the ideas and plans for later labor management. At present, the degree of cervical dilatation is highly subjective and there is no concrete unified standard. After entering the department, new doctors, nurses, and midwives can only practice on patients because there is no specific model to simulate the scene of checking cervical dilatation. Not only are there few opportunities, but also increase the pain and infection risk of patients. After entering the department, nursing students have never been exposed to clinical practice and have no specific concept of cervical dilatation. It is difficult for them to understand and grasp the key points.

[0004] After searching, a Chinese patent with the publication number CN 208985505 U proposes a simple cervical dilation inspection model, including a triangular bracket, the triangular bracket includes at least one inclined mounting panel, the mounting panel is detachably provided with at least two rubber pads, the rubber pads are provided with a recessed portion for simulating the cervical os, the bottom of the recessed portion is provided with a spherical protrusion exposed outside the opening of the recessed portion and used to simulate the top of a baby's head, and the diameter of the recessed portion ranges from 1 to 10 cm. The simple cervical dilation inspection model provided by the utility model can be stably set on the desktop through the triangular bracket, without the need to hold the model by hand, and multiple rubber pad recesses with different calibers can be used to simulate different

[0005] The cervix in the same state makes it easier for medical staff to conduct training and learning on cervical examination.

[0006] Although the above-mentioned device can provide rubber pad depressions of different calibers to simulate various states of the cervical os, which is convenient for learning, the state of the cervical os at the same position is fixed, and it is not convenient to test medical staff through this model, and the state of the cervical os cannot be changed; in addition, during the delivery process of the parturient, the expansion of the cervical os cannot be seen intuitively, and the degree of dilation of the cervical os can only be measured through internal inspection by inserting fingers into the vagina of the parturient.

[0034] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. The components of the embodiments of the present application described and shown in the drawings here can be arranged and designed in various different configurations.

[0035] The inventors have found that in the training of maternal and infant specialist nurses, the assessment of the cervix of expectant mothers is a very important skill. The accuracy of the cervix judgment will directly affect the nurse's judgment of the progress of the labor process of pregnant women and the later labor management ideas and plans. At present, the examination of the degree of cervical dilation is highly subjective and there is no concrete and unified standard. After entering the department, new doctors, nurses, and midwives can only practice on patients because there is no specific model to simulate the examination of cervical dilation. Not only are there few opportunities, but also it increases the patient's pain and risk of infection. After entering the department, nursing students have never been exposed to clinical practice and do not have a specific concept of cervical dilation. It is difficult for them to understand and grasp the key points.

[0036] Based on the above findings, the present application proposes a new teaching aid for the training of maternal and infant specialist nurses. By setting up a transparent observation board, the evaluation process of the cervical os can be visualized during the teaching process, which can improve the nurses' rational understanding and accuracy of the judgment of the dilation state of the cervical os; by designing a simulation board that is detachably connected to the observation board, the position of the simulation board can be adjusted to facilitate testing of medical staff, and the simulated cervical state corresponding to each observation window on the observation board can be changed; a light-blocking layer is provided on the observation board, which can be installed during testing to achieve a light-free environment, so that the person to be tested cannot directly see the simulation board; through the use of model teaching aids in the training and testing process, the nurses' mastery of this knowledge is improved, and the accuracy of the judgment of the cervical os is improved, ultimately ensuring the smooth progress of the pregnant woman's labor and ensuring the safety of mother and baby during delivery.

[0037] Embodiment 1

[0038] See also Figure 1-Figure 8 The present application discloses a new teaching aid for maternal and infant specialist nurse training, comprising a shell body 1, the shell body 1 is a ring structure, one end of which is fixedly connected to an observation plate 2, the observation plate 2 and the shell body 1 are made of transparent materials, and 10 observation windows 201 are opened on the observation plate 2, the observation windows 201 are circular, and are evenly arranged with the center of the observation plate 2 as the center. The observation windows 201 are of the same size.

[0039] A connecting shaft 3 is fixedly connected at the center of one side of the observation plate 2, and the connecting shaft 3 includes an integrally connected connecting shaft 1 301, a connecting shaft 2 302, and a connecting shaft 3 303. The end of the connecting shaft 3 connected to the observation plate 2 is the connecting shaft 1 301, the connecting shaft 1 301 is a cylinder with a larger diameter, the connecting shaft 2 302 is a cylinder with a smaller diameter, and the connecting shaft 3 303 is a stud structure with the same diameter as the connecting shaft 2 302, and an external thread is arranged on the surface.

[0040] The second connecting shaft 302 is provided with a simulation board 4, and a circular groove 401 of 1-10 cm is provided on the simulation board 4, which corresponds to 10 states of expansion during the labor process of pregnant women. A circular connection groove is provided at the center of the simulation board 4. By rotating and adjusting the position of the simulation board 4, the circular groove 401 can correspond to the observation window 201 of the observation board 2 one by one. Through the transparent observation board 2 and the shell body 1, the operation of the internal inspection of the trainer can be visualized, which is convenient for teaching.

[0041] The connection shaft 3 303 is threadedly connected with a limit nut 5, and the limit nut 5 contacts one side of the simulation board 4, so that the position of the simulation board 4 is limited between the connection shaft 1 301 and the limit nut 5, and it will not move easily to affect the teaching effect. The connection shaft 3 303 is also provided with a rear plate 6, which is threadedly connected to the connection shaft 3 303. The rear plate 6 is a cylindrical structure, and the outer peripheral surface contacts the inner peripheral surface of the shell body 1.

[0042] In order to facilitate the determination of the position of the simulation board 4, an arcuate groove 402 is opened on the outer circumference of the simulation board 4, which is compatible with the arcuate guide bar 101 set on the inner circumference of the shell body 1. The simulation board 4 is slidably connected to the shell body 1 and moves inward along the guide bar 101 until it contacts the connecting shaft 301.

[0043] The guide strip 101 corresponds to the observation window 201 on the observation board 2. Therefore, as long as the simulation board 4 matches the position of the guide strip 101, it can ensure that each observation window 201 corresponds to a circular groove 401 on the simulation board 4. After the training is completed, the training personnel can be assessed through the teaching aid, which can improve the nurses' mastery of the knowledge and the accuracy of the judgment of the cervical opening, ultimately ensuring the smooth progress of the pregnant woman's labor and ensuring the safety of mother and baby during delivery.

[0044] Embodiment 2

[0045] refer to Figure 1 , Figure 9-11 In order to avoid directly seeing the circular groove 401 on the simulation board 4 from the observation window 201 and make the teaching aids more practical, a flexible protective cover 7 is set on the observation window 201. The flexible protective cover 7 includes limiting rings on both sides and a containing tube in the middle. The limiting rings and the containing tube are connected as one piece and are made of deformable materials such as silicone and rubber, which are easy to install and disassemble, and easy to clean and disinfect after the training.

[0046] Embodiment 3

[0047] On the basis of the above technical solution, during testing, a light-blocking layer may be provided on the outside of the observation board 2 and the outer shell body 1 to achieve a light-free environment, so that the person to be tested cannot directly see the simulation board 4.

[0048] The light blocking layer can be a black coating, which can be connected to the observation board 2 and the housing body 1 by electrostatic adsorption; or can be bonded by adhesive tape or the like.

[0049] The use process of this utility model is:

[0050] 1. When used for training and learning, first put the simulation board 4 into the shell body 1, the center is socketed with the limit shaft 2, the outer arc groove 402 is slidably connected with the arc guide strip 101 set on the inner circumference of the shell body 1 until it contacts with the connecting shaft 1 301, install the limit nut 5 to fix the position of the simulation board 4; then install the rear plate 6, and the rear plate 6 is threadedly connected with the connecting shaft 3 303.

[0051] 2. When used for testing training personnel, first place the simulation board 4 into the shell body 1, with the center socketed with the limiting shaft 2, and the outer arc groove 402 slidingly connected with the arc guide strip 101 arranged on the inner circumference of the shell body 1 until it contacts with the connecting shaft 1 301, and install the limiting nut 5 to fix the position of the simulation board 4; then install the rear plate 6, and the rear plate 6 is threadedly connected with the connecting shaft 3 303.

[0052] Then, a light-blocking layer is provided on the outside of the observation board 2 and the outer shell body 1 to achieve a light-free environment, so that the person to be tested cannot directly see the simulation board 4.

[0053] When there are many trainees, the size of the circular groove 401 corresponding to the observation window 201 can be changed by switching the position of the simulation board 4, so as to avoid the tester recording the corresponding circular groove 401 of each observation window 201 by memory, thereby improving the test effect.
