Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of delivery balls, in particular to a delivery ball that displays a balloon pressure value. Background Art
[0002] During childbirth training, pregnant women often use birthing balls to simulate various positions and movements during labor, helping them better understand and adapt to the birthing process. However, traditional birthing balls are mostly simple inflatable spheres that do not provide direct feedback on the internal pressure. The pressure inside the balloon is crucial for pregnant women, as the appropriate pressure can help them better adapt to the pressure of labor and help train the contraction and relaxation of the abdominal and pelvic muscles.
[0003] While existing technologies offer a method for displaying the pressure of a birthing ball by using a birthing ball holder, this approach typically requires additional equipment, namely the birthing ball holder, which not only increases the cost but also limits its flexibility and convenience. Whenever the birthing ball is used in a different location, the user must move both the birthing ball and the holder, which undoubtedly complicates its use. Utility Model Content
[0004] In response to the above-mentioned existing technologies, the present invention provides a delivery ball that displays the balloon pressure value. It does not rely on an additional delivery ball seat and can intuitively display the pressure changes in the balloon. It not only reduces the cost of use, but also improves the flexibility and convenience of use. It is of great significance to improving the effectiveness and comfort of delivery training for pregnant women.
[0005] To achieve the above-mentioned purpose, the technical solution of the embodiment of the utility model is implemented as follows:
[0006] A delivery ball that displays the balloon pressure value includes a balloon body, an indicator tube, an elastic ball and a sealing liquid. The sealing liquid is filled in the indicator tube, dividing the indicator tube into two mutually isolated cavities. One of the cavities is connected to the elastic ball located in the balloon body, and the other cavity is connected to another elastic ball located outside the balloon body or a rigid closed container in the balloon body.
[0007] Furthermore, the indicating tube includes a capillary portion and a connecting portion, the inner diameter of the capillary portion is smaller than the inner diameter of the connecting portion, the connecting portion is used to communicate with the elastic ball or the rigid closed container, and the capillary portion is vortex-shaped.
[0008] Furthermore, a protective pad is fixed on the surface of the balloon body, and the capillary portion is fixedly connected to the protective pad.
[0009] Furthermore, the protective pad is provided with indicator areas of different colors along the direction of the capillary portion, and scales are provided in the indicator areas.
[0010] Furthermore, the elastic ball located in the balloon body is connected to the connecting portion located in the center of the indicator tube.
[0011] Furthermore, a transparent protective film is provided on the outer surface of the protective pad, and the protective film covers the capillary portion.
[0012] Furthermore, the elastic ball is located in a spherical protective box, and the protective box is provided with a through hole for balancing internal and external pressures.
[0013] Furthermore, the through hole is conical, the elastic ball is connected to a baffle, and the side of the baffle facing the through hole is conical.
[0014] Furthermore, the sealing liquid is colored oil.
[0015] Furthermore, the balloon body is provided with an air valve, and the air valve cooperates with the inflation head of the air pump.
[0016] The beneficial effect of the present invention is that when the pressure in the balloon body changes, the pressure of the elastic ball squeezed in the balloon body also changes, thereby squeezing the sealing liquid toward the other end, or the sealing liquid is squeezed over by the other end, and finally the position of the sealing liquid in the indicator tube changes, thereby indicating the pressure change in the balloon. Before training, the pressure indicator can be observed to determine whether the pressure in the balloon body meets the training requirements, and the pressure of the balloon body can be observed during training to determine the effect of the training. The present invention does not require an additional delivery ball seat and can intuitively display the pressure changes in the balloon, which not only reduces the cost of use, but also improves the flexibility and convenience of use. It is of great significance to improving the effect and comfort of delivery training for pregnant women. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] Example 1
[0029] Please refer to the attached Figures 1 to 4The present application provides a delivery ball that displays balloon pressure values, comprising a balloon body 1, an indicator tube 2, an elastic ball 3, and a sealing liquid 4. The sealing liquid 4 is filled in the indicator tube 2, dividing the indicator tube 2 into two mutually isolated cavities: one cavity is connected to the elastic ball 3 located within the balloon body 1, and the other cavity is connected to the other elastic ball 3 located outside the balloon body 1. The balloon body 1 is filled with gas at a preset pressure, causing the balloon body 1 to expand, allowing pregnant women to perform delivery training. The outer surface of the balloon body 1 is provided with an indicator tube 2. The indicator tube 2 is divided into two independent cavities by a sealing liquid 4. Each cavity is connected to an elastic ball 3, one of which is located inside the balloon body 1 and the other outside. The elastic ball 3 inside the balloon body 1 is subject to the air pressure inside the balloon body 1, while the elastic ball 3 outside the balloon body 1 is subject to the air pressure outside the balloon body 1. When the pressure inside the balloon body 1 changes, the pressure pressing on the elastic ball 3 inside the balloon body 1 also changes, thereby squeezing the sealing liquid 4 toward the other end, or the sealing liquid 4 is squeezed toward the other end, ultimately causing the position of the sealing liquid 4 inside the indicator tube 2 to change, thereby indicating the pressure change inside the balloon. Before training, the pressure indicator can be observed to determine whether the pressure inside the balloon body 1 meets the training requirements. The pressure of the balloon body 1 can also be observed during training to determine the training effect. This utility model does not require an additional birthing ball seat and can intuitively display the pressure changes inside the balloon. This not only reduces the cost of use but also improves the flexibility and convenience of use. It is of great significance for improving the effectiveness and comfort of childbirth training for pregnant women.
[0030] Specifically, the indicator tube 2 includes a capillary portion 6 and a connecting portion 7. The inner diameter of the capillary portion 6 is smaller than that of the connecting portion 7. The connecting portion 7 is used to connect to the elastic ball 3. The capillary portion 6 has a spiral shape. The diameter of the connecting portion 7 is larger than that of the capillary portion 6. When the elastic ball 3 undergoes a slight volume change, the sealing liquid 4 within the capillary portion 6 moves significantly, allowing for more intuitive and rapid determination of pressure changes. The spiral shape of the capillary portion 6 effectively utilizes the surface space of the balloon body 1.
[0031] Specifically, a protective pad 8 is fixed on the surface of the balloon body 1, and the capillary portion 6 is fixedly connected to the protective pad 8. After the balloon body 1 is inflated, the protective pad 8 can reduce the deformation of the area, thereby protecting the indicator tube 2 and other components.
[0032] Specifically, the protective pad 8 is provided with indicator areas 9 of different colors along the capillary portion 6, and a scale 10 is provided within the indicator area 9. The color indicator area 9 allows for a quick and preliminary assessment of the pressure value, and further accurate readings are obtained using the scale 10 within the indicator area 9, enabling a more rapid and intuitive assessment of the pressure value within the balloon body 1. Alternatively, colors can be used to indicate an appropriate pressure value, indicating that inflation or deflation is required when the pressure exceeds or falls below the specified value.
[0033] Specifically, the elastic ball 3 within the balloon body 1 is connected to a connection portion 7 located at the center of the indicator tube 2. The inner cavity of the elastic ball 3 connected to the connection portion 7 located at the center of the indicator tube 2 can be filled with air, completely filled with sealing fluid, or partially filled with sealing fluid. When the volume of the elastic ball 3 within the balloon body 1 is connected to the central connection portion 7, the sealing oil within the indicator tube 2 changes from the center to the periphery, allowing for intuitive and rapid assessment of pressure changes within the balloon body 1.
[0034] Specifically, a transparent protective film 11 is provided on the outer surface of the protective pad 8, and the protective film 11 covers the capillary portion 6. The protective film 11 protects the capillary portion 6 to prevent wear and damage.
[0035] Optionally, the sealing liquid 4 is colored oil, which is not easy to evaporate and can be easily observed.
[0036] Optionally, the balloon body 1 is provided with an air valve 15 that cooperates with an inflation head of an air pump. When the air pressure in the balloon body 1 is insufficient, air can be inflated into the balloon body 1 through the air valve 15. Preferably, the air pump is equipped with an air pressure sensor, and after the air valve 15 is connected to the inflation head, the air pump automatically inflates the balloon body 1.
[0037] Example 2
[0038] Please refer to the attached Figure 5 This embodiment differs from Example 1 in that the elastic ball 3 is located within a spherical protective case 12, which is provided with a through hole 13 for balancing internal and external pressure. After the elastic ball 3 expands to a certain size, it contacts the inner wall of the protective case 12, supporting the elastic ball 3 from all sides to prevent it from rupturing due to excessive deformation. Through hole 13 balances the air pressure on both sides of the spherical shield.
[0039] Specifically, the through-hole 13 is tapered, and the elastic ball 3 is connected to a baffle 14, which is tapered on the side facing the through-hole 13. After the deformation reaches a predetermined value, the baffle is pushed and embedded into the through-hole 13. The outer surface of the baffle mates with the outer surface of the spherical guard, ensuring a smooth contact surface of the elastic ball 3 and preventing damage to the elastic ball 3. Optionally, a portion of the elastic ball 3 is bonded to the baffle 14.
[0040] Example 3
[0041] Please refer to the attached Figures 6-7 The difference between this embodiment and embodiment 1 or 2 is that one of the cavities is connected to the elastic ball 3 located in the balloon body 1, and the connection of the other cavity is replaced by a connection to the rigid closed container 5 located in the balloon body 1, and the connecting parts 7 at both ends of the indicator tube 2 are respectively used to communicate with the elastic ball 3 and the rigid closed container 5. One elastic ball 3 is located in the closed container, and is affected by the pressure in the rigid closed container 5. The pressure in the rigid closed container 5 is not affected by the pressure of the balloon body 1. When the pressure in the balloon body 1 changes, the volume of the elastic ball 3 changes, thereby causing the sealing liquid 4 to move in the indicator tube 2. Since both the rigid sealed container and the elastic ball 3 are located in the balloon body 1, the integrity of the outer surface of the balloon body 1 can be ensured to a greater extent. Preventing the formation of a rigid area on the outer surface of the balloon body 1 reduces discomfort during delivery training.
[0042] The above are only specific embodiments of the present invention, but the scope of protection of the present invention is not limited to them. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in this utility model should be included in the scope of protection of the present utility model. The scope of protection of the present utility model should be based on the scope of protection of the claims.
