Abstract
Description
Technical Field
[0001] The utility model relates to the field of medical auxiliary experience equipment, in particular to a uterine contraction simulator. Background Art
[0002] Uterine contractions are divided into false contractions and true contractions. False contractions are common in late pregnancy and are generally not dangerous, so there is no need to seek medical attention. However, when false contractions are too intense, there is a risk of causing true contractions, which can lead to premature delivery of the fetus. In this case, you need to go to the hospital for medical treatment in time if you find that the false contractions are too severe. However, different pregnant women have different physical conditions, and the symptoms of false contractions are also different. Some pregnant women will not feel pain even if the false contractions are obvious, which makes it difficult for pregnant women to pay attention. In addition, pregnant women are not medical personnel, and it is usually difficult for them to judge the degree of contractions independently. Therefore, it is very necessary to enable pregnant women to make their own preliminary judgment on the degree of contractions.
[0003] Whether it is a false or true contraction, the abdomen will become tight and hard during the contraction. At this time, by touching the abdomen, the degree of contraction can be judged by the hardness of the abdomen. There is currently a kind of contraction experience simulation teaching aid disclosed in application number CN201821811578.5, which uses a contraction simulation bag for simulation. During the simulation, the contraction simulation bag is inflated by a connected air bag to increase the air pressure in the contraction simulation bag, so that the contraction simulation bag shows different hardness. However, in actual operation, when the air pressure in the contraction simulation bag increases, the volume of the contraction simulation bag will also increase significantly. During the contraction, the pregnant woman's abdomen will not have such a big change, so the simulation effect of the existing technology on the pregnant woman's abdomen will deteriorate. When the hand contacts the contraction simulation bag, the change in the volume of the contraction simulation bag causes the arc of the contraction simulation bag surface to change. Therefore, when the hand contacts the surface of the contraction simulation bag, the curvature of the palm will also change, that is, the contact position of the palm and the contraction simulation bag changes, resulting in interference with the hardness change and reduced learning efficiency. Utility Model Content
[0004] The utility model aims to provide a uterine contraction simulator to solve the problem that the volume changes greatly during simulation, resulting in poor simulation effect.
[0005] To achieve the above-mentioned purpose, the present invention adopts the following technical solution: a uterine contraction simulator, comprising a base, a rotating column and an outer shell, the rotating column being vertically arranged on the base and rotatably connected to the base, a plurality of simulation parts being circumferentially arranged on the rotating column, the cross-section of the simulation part surface along the radial direction of the rotating column being arc-shaped, and the hardness of adjacent simulation parts gradually increasing; the outer shell being mounted on the rotating column, and the outer shell being provided with a window that can be aligned with the simulation part.
[0006] The beneficial effects of this program are:
[0007] 1. The multiple simulators in this scheme have different hardnesses, so they can simulate the different hardnesses of the pregnant woman's abdomen during different degrees of uterine contractions. By feeling the hardness of different simulated parts, pregnant women can understand the relationship between abdominal hardness and the degree of uterine contractions, thereby assisting pregnant women to quickly judge the degree of uterine contractions by the hardness of the abdomen when the abdomen is tight and hard. In this way, when uterine contractions are severe in the late pregnancy, they can be discovered in time, making it easier to go to the hospital for medical treatment, avoiding the serious degree of false uterine contractions in the late pregnancy due to the pregnant woman's lack of understanding of the degree of uterine contractions and failure to seek medical treatment in time, which may cause real uterine contractions and cause danger.
[0008] 2. This solution simulates different degrees of uterine contractions through simulation parts of different hardness. Compared with the existing technology that requires inflation through airbags during simulation, in this solution, there is no need to inflate the simulation part during the simulation process. Therefore, after the pregnant woman's hand comes into contact with the simulation part, the volume of the simulation part will not change too much. Therefore, the simulator is more similar to the abdomen of a real pregnant woman, and the simulation effect is better.
[0009] Furthermore, the simulation portion is a spherical surface.
[0010] The beneficial effect of this solution is that the simulation part in this solution is more similar to the abdomen of a pregnant woman and can perform better simulation.
[0011] Furthermore, the relative position between the housing and the simulation part is also spherical.
[0012] The beneficial effect of this solution is that after the shell in this solution accommodates the simulation part, the space between the shell and the simulation part is smaller, making the structure of the entire simulator more compact.
[0013] Furthermore, a sealing film is fixed on the housing, and the sealing film covers and seals the window.
[0014] This solution offers the following benefits: the sealing film prevents pregnant women's hands from coming into direct contact with the simulator. After use by one pregnant woman, the film can be disinfected by spraying it with alcohol, preventing cross-infection when the next pregnant woman uses it. Compared to disinfecting the simulator directly, this solution maintains the sealant's position and is unobstructed by the outer shell, resulting in a more effective disinfection.
[0015] Furthermore, a receiving space is formed between the rotating column and the shell, and the receiving space is connected to the exhaust member.
[0016] The beneficial effect of this solution is that the air in the accommodating space can be discharged through the exhaust component, so that the air pressure in the accommodating space is lower than the external air pressure, so that the sealing film is attached inward to the simulation part, allowing pregnant women to better feel the hardness of the simulation part.
[0017] Furthermore, a plurality of limiting grooves are provided on the rotating column along the circumferential direction, and the number of the limiting grooves is equal to the number of the simulation parts. The limiting grooves correspond to the simulation parts one by one, and one end of the simulation part is located in the limiting groove.
[0018] The beneficial effect of this solution is that the limiting groove in this solution can limit the simulation part to prevent the simulation part from falling off.
[0019] Furthermore, the simulation part is an airbag, and a pressurized medium is provided in the airbag. The pressure in the multiple simulation parts gradually increases, and the volumes of all the simulation parts are equal.
[0020] The beneficial effect of this solution is that the hardness of the airbag can be adjusted by the amount of pressurized medium introduced into the airbag, thereby simulating different degrees of uterine contractions, while the volume of the simulation part remains unchanged, so that when pregnant women touch different simulation parts, they will not have different feelings due to changes in the size of the simulation parts, thereby ensuring that pregnant women can more clearly feel and distinguish the hardness of different simulation parts.
[0021] Furthermore, a plurality of labels are provided on the top of the rotating column along the circumferential direction. The labels correspond to the simulation parts one by one and are located directly above the simulation parts.
[0022] The beneficial effect of this solution is that different analog parts can be distinguished by the labels above, so that different analog parts can be quickly identified. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] The following is further described in detail through specific implementation methods:
[0028] The reference numerals in the drawings of the specification include: base 1, exhaust part 11, air pipe 12, rotating column 2, limiting groove 21, upper rotating shaft 3, connecting rod 31, label 4, simulation part 5, shell 6, accommodating space 61, window 61, sealing film 7.
[0029] Example 1
[0030] Example 1 is basically as Figure 1As shown, a uterine contraction simulator includes a base 1, a rotating column 2, a housing 6, four labels 4 and four simulation parts 5. The base 1, the housing 6 and the labels 4 are arranged in sequence from bottom to top. Please refer to Figure 2 The rotating column 2 is vertically arranged on the base 1. The bottom and top of the rotating column 2 are coaxially welded with a lower rotating shaft and an upper rotating shaft 3 respectively. An inner cavity is provided in the base 1. The lower rotating shaft vertically penetrates the top of the inner cavity, and a bearing is provided between the lower rotating shaft and the base 1.
[0031] The outer shell 6 is positioned over the outer surface of the rotating column 2, with the bottom of the outer shell 6 welded to the top of the base 1. The central portion of the rotating column 2 is spherical, and the portion of the outer shell 6 opposite the spherical portion of the rotating column 2 is also spherical. The upper rotating shaft 3 vertically extends through the top of the outer shell 6, and a bearing is provided between the upper rotating shaft 3 and the outer shell 6 to ensure that the rotating column 2 can rotate relative to the outer shell 6.
[0032] Four arc-shaped limit slots 21 are evenly arranged along the circumference of the central portion of the rotating column 2. Four labels 4 are opposite to the upper rotating shaft 3 and are respectively located directly above the four limit slots 21. Each label 4 is vertically arranged and each label 4 is arc-shaped. A connecting rod 31 is provided between the label 4 and the upper rotating shaft 3. One end of the connecting rod 31 is glued to the upper rotating shaft 3 and the other end is glued to the label 4. The four simulation parts 5 are respectively arranged in the four limit slots 21, and the center of gravity of the simulation part 5 is located in the limit slot 21. The end of the simulation part 5 away from the rotating column 2 extends outside the limit slot 21. Please refer to Figure 3 The right side wall of the housing 6 is provided with a window 61 facing the simulation unit 5. The simulation unit 5 uses an airbag with a built-in pressurized medium. In this embodiment, the pressurized medium is air. In actual implementation, liquids such as water and oil, or solids such as rubber or silicone with different elasticities can also be used. The air pressure in the four airbags in this embodiment gradually increases. When the pressurized medium is built in, the four airbags have equal volumes. The four limiting grooves 21 are also the same size and shape, so that after the airbags are installed in the limiting grooves 21, the shape and size of the outward-facing curved surfaces of the airbags are the same. Specifically, the four airbags in this embodiment have different initial sizes and wall thicknesses. Therefore, after the same amount of air is introduced, the air pressure in the four airbags is different, thereby simulating the hardness of the abdomen during different degrees of uterine contractions. In actual implementation, the four airbags can also be made of materials with different elasticity and hardness, so that the four airbags have the same volume after inflation but different internal air pressures, simulating different hardnesses.
[0033] The specific implementation process is as follows:
[0034] In this embodiment, different labels 4 can be distinguished by writing different numbers, letters, or symbols on them, thereby distinguishing the simulation parts 5 below the labels 4. When a pregnant woman wants to feel the hardness of the abdomen under different degrees of uterine contractions, the different simulation parts 5 are rotated to a position opposite to the window 61. The pregnant woman's hand can pass through the window 61 to contact the simulation part 5. By lightly pressing the simulation part 5 with her hand, the hardness of the simulation part 5 can be felt. When it is necessary to feel the hardness of the abdomen under another uterine contraction, the pregnant woman's palm is first removed from the simulation part 5. Then, the rotating column 2 is manually rotated to rotate the adjacent simulation part 5 to the window 61. The pregnant woman can then contact the next simulation part 5 and feel the hardness of the abdomen under different degrees of uterine contractions.
[0035] Example 2
[0036] like Figure 4 As shown, on the basis of Example 1, the right side wall of the shell 6 in this embodiment is provided with a window 61 facing the simulation part 5 and is provided with a flexible sealing film 7. The sealing film 7 in this embodiment is made of soft plastic material. The sealing film 7 covers the window 61 and seals the window 61. At the same time, the outer edge of the sealing film 7 is glued and fixed to the side wall of the shell 6.
[0037] An accommodating space 61 is formed between the outer shell 6 and the rotating column 2. An exhaust component 11 is provided in the base 1. An air pipe 12 is provided between the air inlet end of the exhaust component 11 and the accommodating space 61 for communication. The exhaust component 11 in this embodiment adopts a micro air pump, and the side wall of the outer shell 6 is provided with an air vent connected to the inner cavity; at the same time, the accommodating space 61 is also connected to the exhaust pipe, and the exhaust pipe is connected to the air inlet component.
[0038] The difference from Example 1 is that the pregnant woman's hand in this embodiment will not directly contact the simulation part 5. When the pregnant woman feels the hardness of the lower abdomen at different degrees of uterine contraction, the different simulation parts 5 are rotated to a position relative to the window 61, and the exhaust part 11 is started to expel the excess air in the accommodating space 61 as much as possible to facilitate the adhesion of the sealing film 7 to the simulation part 5. At this time, the palm of the pregnant woman can be in contact with the sealing film 7 and press on the simulation part 5 at the same time.
[0039] When it is necessary to feel the firmness of the abdomen during another contraction, the pregnant woman's palm is first removed from the sealing film 7. At the same time, the exhaust member 11 is closed and the air inlet member is opened. The air inlet member allows gas to flow in. Since the sealing film 7 is soft, it bulges outward after the gas enters the accommodation space 61, thus separating from the simulation part 5. This prevents the simulation part 5 from interfering with the sealing film 7 during rotation. The rotating column 2 is then manually rotated to rotate the adjacent simulation part 5 to the window 61. The air inlet member is then closed and the above steps are repeated to attach the sealing film 7 to the next simulation part 5.
[0040] In actual implementation, when the sealing film 7 is made of a smooth elastic material, the middle part of the rotating shaft and the surface of the simulation part 5 are smooth, and the sealing film 7 has been pushed outward by the rotating column 2 and the simulation part 5, since the sealing film 7 is already in contact with the simulation part 5, the exhaust part 11 and the trachea 12 may not be provided at this time. When in use, the palm of the pregnant woman can be pressed on the simulation part 5 by contacting the sealing film 7.
[0041] After use, spray alcohol on the surface of the sealing film 7 for disinfection to avoid cross infection.
[0042] The above description is merely an embodiment of the present invention, and the commonly known specific technical solutions and / or features of the solution are not described in detail here. It should be noted that for those skilled in the art, without departing from the technical solution of the present invention, several variations and improvements can be made, which should also be considered as the scope of protection of the present invention, and these will not affect the effect of the implementation of the present invention and the practicality of the patent. The scope of protection claimed in this application shall be based on the content of its claims, and the specific implementation methods and other records in the specification can be used to interpret the content of the claims.
