Description

Technical Field

[0001] The present invention relates to the field of medical technology, and more particularly to a gynecological and obstetrics maternal milk accumulation prevention device. Background Art

[0002] Breast engorgement is common after childbirth, and this is due to improper or infrequent breastfeeding. Improper or infrequent breastfeeding can cause milk to accumulate in the breasts, leading to "milk accumulation." If the remaining milk in the breasts is not expressed promptly, it can accumulate and become sour, which can easily lead to the development of Staphylococcus aureus, which can infect the child's lungs after breastfeeding.

[0003] Therefore, many mothers use breast pumps to assist in milk discharge. Breast pumps usually use the principle of negative pressure suction to suck milk from the breasts of lactating women. Existing breast pumps include a suction cup, a feeding bottle, a connecting tube assembly, and a power assembly. The suction cup wraps around the breast of the lactating mother, the connecting tube assembly is used to connect the suction cup and the feeding bottle, the power assembly enables the device to suck out milk in a negative pressure state, and the connecting tube assembly can guide the milk into the feeding bottle for storage. However, in the above-mentioned prior art, when the milk is sucked out, milk will remain inside the connecting tube assembly, causing waste. Moreover, when the suction cup is removed from the breast, the milk in the connecting tube assembly loses suction and is easy to overflow and wet clothes. For this reason, a device for preventing milk accumulation for obstetrics and gynecology is proposed. Summary of the Invention

[0038] like Figures 1 to 2 As shown, an embodiment of the present invention provides a gynecological and obstetric device for preventing milk accumulation, comprising a feeding bottle 1, an outer cover 2, and a connecting portion 31. The feeding bottle 1 and the outer cover 2 are both mounted on the outer surface of the connecting portion 31. A connecting tube 32 is mounted inside the connecting portion 31. Both ends of the connecting tube 32 extend outside the connecting portion 31 to connect the feeding bottle 1 and the outer cover 2, respectively. A valve body is provided inside one end of the connecting tube 32 located in the outer cover 2.

[0039] The connecting tube 32 is composed of a horizontal section a, a major arc section b and a vertical section c. The horizontal section a is connected to the outer cover 2, and the vertical section c is connected to the feeding bottle 1. The horizontal section a and the major arc section b are respectively provided with a first squeezing mechanism and a second squeezing mechanism. The first squeezing mechanism and the second squeezing mechanism drain the milk inside the connecting tube 32 by squeezing the horizontal section a and the major arc section b.

[0040] The surface of the connecting portion 31 is fixedly connected to a connecting tube 9, which is located outside the vertical section c of the connecting tube 32 and is threadedly connected to the feeding bottle 1. The surface of the connecting tube 9 is fixedly connected to an air pipe 10, and the outer surface of the connecting portion 31 is fixedly connected to a pump 11, and one end of the air pipe 10 is fixedly installed on the air port of the pump 11.

[0041] The valve body in this embodiment can be used in conjunction with any existing type of solenoid valve component to meet the simple liquid outflow control; in this embodiment, the solenoid valve model can be selected from BZCD-1. At the same time, a button can be provided on the outer surface of the connecting part 31, and a battery assembly can be provided on the connecting part 31 or any other part to provide corresponding power to the valve body. Pressing the button can control the switch of the solenoid valve.

[0042] The outer cover 2 is used to fit the breast, and the outer cover 2 and the connecting portion 31 are threadedly connected. During actual use, a silicone inner layer can be provided inside the outer cover 2 to fit the skin better and improve the airtightness of the device. When expressing milk, the outer cover 2 is placed on the breast and the button is pressed to open the valve body to keep the connecting tube 32 connected. The pump 11 is then started to use the air tube 10 to extract the gas inside the feeding bottle 1, so that the feeding bottle 1 is in a negative pressure state. Therefore, milk can be sucked into the feeding bottle 1 through the connecting tube 32. When use is finished, the button is pressed again to close the valve body, and the first squeezing mechanism is used to compress the horizontal section a of the connecting tube 32, so that the milk in the horizontal section a of the connecting tube 32 flows into the major arc section b of the connecting tube 32. The second squeezing mechanism is used to repeatedly squeeze the major arc section b of the connecting tube 32, so that the milk in the connecting tube 32 completely flows into the feeding bottle 1, avoiding milk residue in the connecting tube 32, reducing waste, and preventing the milk in the connecting tube 32 from flowing out and wetting clothes when the outer cover 2 is removed.

[0043] like Figure 3 As shown, the first extrusion mechanism includes a groove body 42 opened on one side of the connecting part 31, the horizontal section a of the connecting tube 32 is located inside the groove body 42, and electric push rods 43 are fixedly connected to both sides of the groove body 42. The telescopic sections of the electric push rods 43 are fixedly connected to the pressure plates 41, and the horizontal section a of the connecting tube 32 is located between the two groups of pressure plates 41.

[0044] In this embodiment, after use is completed and the valve body is closed, the electric push rod 43 is driven to extend, driving the pressure plate 41 to squeeze the horizontal section a of the connecting pipe 32, so that the emulsion in the horizontal section a of the connecting pipe 32 flows into the arc section b of the connecting pipe 32.

[0045] like Figure 2 and Figure 4 As shown, the second extrusion mechanism includes an inner groove 33 opened inside the connecting portion 31, the inner groove 33 is set to be circular, the major arc segment b of the connecting tube 32 is fitted inside the inner groove 33, a rotating shaft 52 is rotatably connected to the center of the inner groove 33, the outer surface of the rotating shaft 52 is fixedly connected to a connecting rod 53 along its radial direction, a pressure roller 54 is rotatably mounted on one end of the connecting rod 53, and the pressure roller 54 is in rolling engagement with the inner surface of the inner groove 33.

[0046] The motor 51 is fixedly mounted on the outer surface of the connecting portion 31 , and one end of the rotating shaft 52 extends outside the connecting portion 31 and is fixedly connected to the output shaft of the motor 51 .

[0047] In this embodiment, after the horizontal section a of the connecting tube 32 is compressed by the first squeezing mechanism, the motor 51 is used to drive the rotating shaft 52, the connecting rod 53 and the pressure roller 54 to rotate, and the pressure roller 54 can repeatedly squeeze the major arc section b of the connecting tube 32. When the pressure roller 54 squeezes the major arc section b of the connecting tube 32 for the first time, the emulsion inside the major arc section b of the connecting tube 32 can be squeezed into the vertical portion c of the connecting tube 32. When the pressure roller 54 subsequently squeezes the major arc section b of the unloaded connecting tube 32, it can provide power for the emulsion in the vertical portion c of the connecting tube 32, thereby accelerating the discharge of the emulsion inside the vertical portion c of the connecting tube 32 into the interior of the feeding bottle 1.

[0048] like Figures 2 to 6 As shown, the inner groove 33 is provided with a control mechanism on one side of the vacant section of the major arc segment b, and the control mechanism is used to control the opening and closing of the first extrusion mechanism. The pressure roller 54 moves to contact with the control mechanism to start the first extrusion mechanism.

[0049] The control mechanism includes a slide groove 66 opened on one side of the inner groove 33, an arc-shaped groove 61 is opened inside the connecting part 31, the arc-shaped groove 61 is connected to the slide groove 66, a conductive sheet 62 is fixedly connected inside the arc-shaped groove 61, a slider 64 is installed inside the slide groove 66, one end of the slider 64 located inside the arc-shaped groove 61 is fixedly connected to a conductive block 65, an arc spring 63 is fixedly connected to one side of the inner surface of the arc-shaped groove 61, one end of the arc spring 63 is fixedly connected to the slider 64, an electromagnet 67 is fixedly connected to the surface of the connecting rod 53, and the slider 64 is magnetic at one end of the slide groove 66, and the electromagnet 67 can adsorb the slider 64 when energized.

[0050] During the process of the connecting rod 53 rotating from the vertical section c of the connecting tube 32 to the horizontal section a, the electromagnet 67 attracts the slider 64 to move, so that the conductive block 65 contacts the conductive sheet 62 and moves the conductive block 65 to the proximal end of the horizontal section a of the connecting tube 32. The time it takes for the conductive block 65 to move back to the separated conductive sheet 62 is greater than the time it takes for the electromagnet 67 to rotate one circle.

[0051] In this embodiment, by setting a control mechanism, the first extrusion mechanism can be automatically controlled. Specifically, the motor 51 and the electromagnet 67 are started, and the motor 51 can drive the pressure roller 54 and the electromagnet 67 to rotate. During the process of the pressure roller 54 and the electromagnet 67 rotating from the vertical section c of the connecting tube 32 to the horizontal section a, the electromagnet 67 attracts the slider 64 and the conductive block 65 to move, so that the conductive block 65 moves to contact with the conductive sheet 62, and at this time the arc spring 63 is compressed. The contact between the conductive block 65 and the conductive sheet 62 can start the first extrusion mechanism, so that the first extrusion mechanism squeezes the horizontal section a of the connecting tube 32 before the pressure roller 54 squeezes the superior arc section b of the connecting tube 32. As the pressure roller 54 continues to rotate, the pressure roller 54 can squeeze the superior arc section b of the connecting tube 32. In addition, the electromagnet 67 gradually moves away from the slider 64, and the compressed arc spring 63 stretches and contracts, driving the conductive block 65 to move back; because the arc spring 63 drives the conductive block 65 back to the position where the conductive sheet 62 is separated The time is greater than the time it takes for the electromagnet 67 to rotate one circle. When the pressure roller 54 and the electromagnet 67 rotate to the side of the slider 64 again, the conductive block 65 has not yet separated from the conductive sheet 62. The electromagnet 67 continues to attract the slider 64 and the conductive block 65 to move to the proximal end of the horizontal section a of the connecting tube 32, causing the arc spring 63 to be compressed again. Therefore, during the continuous rotation of the pressure roller 54 and the electromagnet 67, the conductive block 65 is always in contact with the conductive sheet 62, thereby maintaining the first squeezing mechanism to compress the horizontal section a of the connecting tube 32. When the milk in the connecting tube 32 is completely discharged into the interior of the feeding bottle 1, the motor 51 drives the pressure roller 54 and the electromagnet 67 to move to the original position, and the power supply of the motor 51 and the electromagnet 67 is turned off. The compressed arc spring 63 can then fully extend, driving the slider 64 and the conductive block 65 to return to their original position, causing the conductive block 65 to separate from the conductive sheet 62, thereby closing the first squeezing mechanism so that the first squeezing mechanism no longer compresses the horizontal section a of the connecting tube 32.

[0052] like Figures 4 to 6As shown, a cylindrical groove 71 is provided inside the electromagnet 67, and a circular plate 73 is installed inside the cylindrical groove 71. A limiting rod 72 is fixedly connected to the center of the circular plate 73. Both ends of the limiting rod 72 pass through the electromagnet 67, and a magnetic block 75 is fixedly connected to the side of the limiting rod 72 away from the arc surface of the inner groove 33. A limiting hole that matches the limiting rod 72 is provided on the side of the inner groove 33 close to the vertical section c of the connecting pipe 32. A connecting spring 74 is sleeved on the surface of the limiting rod 72, one end of the connecting spring 74 is fixedly connected to the circular plate 73, and the other end of the connecting spring 74 is fixedly connected to the cylindrical groove 71. When the electromagnet 67 is energized, the magnetic block 75 is repelled, so that the magnetic block 75 drives the limiting rod 72 to move out of the limiting hole.

[0053] In this embodiment, by setting a limit rod 72 and using it in conjunction with the limit hole, the initial movement position of the pressure roller 54 can be fixed. The initial movement position of the pressure roller 54 is located at the proximal end of the vertical section c of the connecting tube 32 but does not contact the vertical section c of the connecting tube 32. At this time, one end of the limit rod 72 is inside the limit hole, and the limit rod 72 forms a moving interference with the pressure roller 54, thereby fixing the initial movement position of the pressure roller 54. When it is necessary to squeeze the emulsion inside the connecting tube 32, it is necessary to turn on the power of the electromagnet 67. Since the electromagnet 67 repels the magnetic block 75, the magnetic block 75 drives the limit rod 72 and the circular plate 73 to move. The limiting rod 72 can thus move into the limiting hole, no longer interfering with the movement of the pressure roller 54, and the circular plate 73 will compress the connecting spring 74 when it moves. After the first squeezing mechanism and the second squeezing mechanism have completely discharged the milk in the connecting tube 32 into the feeding bottle 1, the power supply of the electromagnet 67 is first turned off, and then the motor 51 is used to drive the pressure roller 54 and the electromagnet 67 to rotate slowly. When the limiting rod 72 is aligned with the limiting hole, the compressed connecting spring 74 extends, driving the limiting rod 72 to move into the limiting hole, thereby limiting the pressure roller 54. Therefore, after each use, the position of the pressure roller 54 can be guaranteed to be the same.

[0054] like Figures 6 to 8 As shown, a pull rope 81 is fixedly connected to the surface of the magnetic block 75, and the interior of the rotating shaft 52 is set to be hollow for the pull rope 81 to pass through. One end of the pull rope 81 extends from the end of the rotating shaft 52 and is fixedly connected to the telescopic rod 82. A slide 83 is fixedly connected to the outer surface of the rotating shaft 52. A movable groove 84 is provided inside the slide 83, and limiting grooves 86 are provided on both sides of the upper surface of the movable groove 84. A movable groove 89 is provided on the outer surface of one end of the telescopic rod 82 located outside the rotating shaft 52, and a control block 87 is installed in the movable groove 89. A support spring 88 is fixedly connected between the control block 87 and the inner surface of the movable groove 89. One side of the outer surface of the control block 87 is fixedly connected to the control plate 85, and the control plate 85 is located inside the movable groove 84, and the upper surface of the control plate 85 away from the control block 87 is provided with a protrusion that is compatible with the limiting groove 86.

[0055] In this embodiment, by providing mechanisms such as a pull rope 81 and a control block 87, the movement of the limit rod 72 can be manually controlled to meet the use requirements when the electromagnet 67 is not powered. Specifically, when it is necessary to clean the connecting pipe 32, the power supply of the electromagnet 67 is turned off, and the control block 87 is pressed to make the protrusion at the end of the control board 85 move out from the inside of the limit groove 86 on the inner side of the slide 83, and then the telescopic rod 82 is pulled to pull the pull rope 81 and the control board 85 to move, so that the limit rod 72 moves out from the inside of the limit hole. When the protrusion on the control board 85 is When it is aligned with the limiting groove 86 on the opening side of the slide 83, the control block 87 is released, and the support spring 88 drives the control block 87 and the control plate 85 to move upward, so that the protrusion on the control plate 85 is embedded in the limiting groove 86 on the opening side of the slide 83, thereby limiting the limiting rod 72. At this time, the motor 51 is used to drive the pressure roller 54 to rotate. Since the electromagnet 67 is in the off state, it will not trigger the control mechanism to start the first extrusion mechanism to compress the horizontal section of the connecting pipe 32. Therefore, during the rotation of the pressure roller 54, only the connecting pipe 32 will be compressed. 2 superior arc segment b, after the feeding bottle 1 and the outer cover 2 are removed from the connecting portion 31, one end of the vertical portion c of the connecting tube 32 is placed in clean water. Since the pressure roller 54 continuously squeezes the superior arc segment b of the connecting tube 32, a peristaltic effect can be formed, which sucks the clean water into the interior of the connecting tube 32 and discharges it from the other end of the connecting tube 32, thereby completing the cleaning of the connecting tube 32; after the cleaning is completed, press the control block 87 again to move the protrusion at the end of the control plate 85 out of the limiting groove 86 on the opening side of the slide seat 83, and then push the telescopic rod 82 to drive the control plate 85 to move out of the limiting groove 86 on the opening side of the slide seat 83. The control plate 85 moves. When the protrusion on the control plate 85 is aligned with the limit groove 86 on the inner side of the slide 83, the control block 87 is released, and the support spring 88 drives the control block 87 and the control plate 85 to move upward, so that the protrusion on the control plate 85 is embedded in the limit groove 86 on the inner side of the slide 83. Then, the motor 51 is used to drive the pressure roller 54 and the electromagnet 67 to rotate slowly. When the limit rod 72 is aligned with the limit hole, the compressed connecting spring 74 extends, driving the limit rod 72 to move into the limit hole, thereby limiting the pressure roller 54.

[0056] It should be noted that, during cleaning, the rotation direction of the motor 51 needs to be adjusted so that the pressing roller 54 rotates in the opposite direction.
