Description

Breast pump system {SYSTEM OF PRESSING MILK}

It is an object of the present invention to manufacture a breast pump that does not cause any pain of the nipple even when the milk is sucked out by high vacuum pressure.

The present invention relates to a breast pump that sucks milk by vacuum pressure. There are many inventions in the art as well. The present invention relates to a painless high vacuum pump that is equally applicable to human breast pumps as well as cows. In more detail, the field of the present invention is an invention for the technical field of removing the pain of the nipple when performing breast pumping.

When the milk is sucked out by vacuum pressure, the amount of milk sucked increases as the vacuum pressure increases, but in the past, the milk cannot be sucked by high vacuum due to pain caused by the expansion of the nipple. The biggest challenge of breast pumps by vacuum pressure was to eliminate the pain of the nipple during breast pumping. The present invention is a breast pump that does not cause any pain even when the milk is sucked out at high vacuum pressure, and the core of the present invention is to inhibit the expansion of the nipple so as not to cause pain in the nipple even when breast milk is carried out under high vacuum pressure.

The present invention relates to an apparatus for milking in a living body of a human body or a living organism. The present invention is also applied to the milking machine milking milk from cows, the present invention will be described centering on the human breast pump. The breast pump of the present invention is composed of a vacuum generator, a milk container, a nipple coupling part, and a coupling part interconnecting the vacuum generator, the milk container and the nipple coupling part like the conventional breast pump. Here, the vacuum generator includes both a vacuum apparatus using an electric motor and a vacuum apparatus to generate a vacuum by compressing by hand, and the nipple coupling part is made of silicon and made of harmless PVC. The core of the present invention is a nipple coupling having a nipple expansion stop device. The nipple expansion preventing device is a device that prevents the nipple from being expanded by passing the wet from the nipple when the milk is sucked out by the vacuum pressure of the vacuum apparatus. The present invention has the effect that it is possible to milk with a high vacuum to perform efficient breast milk, and to eliminate the pain that was inevitably involved when performing breast milk at high vacuum. In the case of pumping by vacuum pressure, the efficiency of pumping and the amount of pumping are increased as the vacuum pressure increases. However, at the same time, as the vacuum pressure increases, the pain of the nipple increases, so in the past, in order to reduce the pain, only the small vacuum pressure has to be performed. The present invention provides a breast pump that does not involve pain at all while performing breast pumping at high vacuum by identifying and solving a cause for providing pain inevitably occurring at high vacuum pressure. In order to solve the pain caused by high vacuum, conventionally, the material of the nipple coupling part is made of silicon or a soft material. However, in this case, psychological comfort effect can be obtained, but it is not prescribed to solve the cause of the actual problem. Since the cause of pain during high vacuum is due to the forced expansion of the nipple, it is meaningless to provide a soft material for the nipple joint without controlling this expansion. The present invention is a revolutionary invention that completely eliminates the pain of the nipple by installing the nipple expansion stop device in the nipple coupling portion to block the expansion of the nipple against the physical force to inflate and inflate the vacuum pressure forcibly sucked during high vacuum pressure. Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

1 is an explanatory diagram for explaining a general form of a conventional breast pump. The present invention is also based on such a conventional configuration in the overall configuration. The nipple coupling part (1) attached to the nipple and the vacuum generator (2) for generating a vacuum pressure by a motor or manual, the milk reservoir (3) for storing the sucked milk and the nipple coupling part (1) and the jeans The pneumatic generator (2) and the coupling portion (4) for coupling the milk storage container (3) is composed of a basic breast pump. However, in some cases, the nipple coupling portion 1 and the coupling portion 4 may be integrally formed, or may be formed in a separate type.

2 is an explanatory view for explaining the state of the nipple inside the nipple coupling portion 1 when the milk is sucked out by vacuum pressure with a conventional breast pump. By the vacuum pressure, the nipple is forcibly sucked deeply without any external resistance. The higher the vacuum pressure, the deeper the suction. Nipples with sensitive neural networks experience extreme pain due to this forced inhalation. Milk aspiration has nothing to do with nipple aspiration and only vacuum pressure acting on the mammary gland contributes to the aspiration of the milk. Conventional breast pumps have no positive role in the outflow of milk and do not prevent forced swelling of the nipple, which only causes pain.

3 is an explanatory view illustrating a nipple coupling part in which a nipple expansion preventing device, which is the core of the present invention, is formed. The nipple expansion preventing device (8) in the nipple coupling part (6) is a device that allows the nipple to enter inside while allowing the wet sucked out by vacuum pressure. In the present invention, the nipple expansion preventing device 8 may be formed to be detachable from the nipple engaging portion 6. The nipple expansion stop device is located inside the nipple coupling part and forms a plurality of through holes, and is configured to allow wet passage. In front of the nipple expansion preventing device, it is also possible to position the fine net (7) formed a finer through-hole, which is easily removable.

4 is an explanatory view for explaining the process when the milk is sucked out by the vacuum pressure to the nipple engaging portion 6 in which the nipple expansion preventing device 8 of the present invention is formed. The nipple expands and passes through the wet nipple expansion preventing device 8 by the vacuum pressure, and the nipple is not inflated by the nipple expansion preventing device 8.

5 and 6 are explanatory views for explaining a state in which the fine net and the nipple expansion stop device 8 are removed when the nipple expansion stop device 8 is detachably configured as one embodiment of the present invention. Even in the removed state, it can be pumped by vacuum pressure.

FIG. 7 is an explanatory view illustrating the formation of the vacuum suction unit 12 in the nipple engaging portion 6 having the nipple expansion preventing device of FIG. 3. The vacuum suction part is located on the inner surface of the nipple coupling part and consists of an annular wide groove. The vacuum pressure is transmitted to the vacuum suction unit 12 through the vacuum passage 11. When vacuum pressure is generated in the vacuum generator, when the vacuum pressure is transferred to the vacuum adsorption part through the vacuum passage, the vacuum pressure is sucked into the skin of the breast in contact with the vacuum adsorption part, thereby attaching the entire nipple coupling part to the breast. You can make In addition, the milk that is sucked out through the nipple expansion preventing device does not flow into the milk container, but when the milk flows inward, the flow is prevented from flowing down to the breast by blocking the flow in the vacuum suction part. The technique of forming the vacuum adsorption portion on the nipple coupling portion may be configured to the nipple coupling portion independently of the nipple expansion preventing device as the technique of the present invention.

8 is an explanatory diagram illustrating a state in which the nipple coupling part of FIG. 7 is actually applied to the breast.

FIG. 9 is an explanatory diagram for explaining that the vacuum suction part of FIG. 7 is filled with an object having a minute hole to prevent the skin from being sucked in. When the skin of the breast expands into the vacuum suction part by vacuum pressure, the pain is accompanied, so that the skin expansion stop 14 is filled in the vacuum suction part to prevent this. Even when the skin expansion stopper is filled, the vacuum pressure acts the same, so that the nipple coupling part is attached to the breast. In addition, even if the vacuum pressure of the nipple part is lost by configuring the check valve 15 at the other end of the vacuum passage 11, the vacuum pressure of the vacuum suction part may be maintained so that the nipple coupling part is attached to the breast. As an example of a simple reverse displacement, an elastic thin silicon plate may be attached to an end portion of a vacuum passage.

The breast pump of the present invention can be easily applied to cows other than humans, and the scope of the present invention extends to breast pumps of cows. The present invention can be configured by integrally forming the remaining parts of the breast pump except for the milk storage container and the vacuum generator, and this is often easy in actual production. When the nipple coupling portion and the coupling portion are integrally formed, the name is referred to as a breast pump upper structure in the present invention.

Conventionally, when milk is sucked out by vacuum pressure, the amount of milk sucked increases as the vacuum pressure increases, but the milk cannot be sucked by high vacuum due to pain caused by the expansion of the nipple. However, the present invention does not cause pain at all, even if it sucks milk at high vacuum pressure. Therefore, it is possible to efficiently pump by high vacuum and completely solve the pain of the nipple, which was the biggest problem of the conventional breast pump.
