Abstract

PROBLEM TO BE SOLVED: To provide a breast pump capable of executing milking more efficient than heretofore. SOLUTION: A milking part 3 has a milking part body 31 which is formed to a funnel shape covering the breast, a nipple which is formed at the inside wall of this milking part body 31 and an adapter 32 which covers the nipple portion and is similarly formed to the funnel shape. The thicknesses of the milking part 31 and the elastic body of the adapter 32 are gradually decreased toward their front ends. Then, the foot portion of the breast and the outer peripheral portion of the areola of mamma are eventually preferentially and more strongly oppressed and released of oppression and are further eventually successively oppressed toward the front end from the foot portion of the breast and toward the breast direction from the outer peripheral portion of the areola of mamma and, therefore, the efficient milking is made possible.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a breast pump, and more particularly, to a breast pump having a better milking property as compared with the prior art.

[0002]

2. Description of the Prior Art A breast pump equipped with a power source, for example, an electric motor, is provided with a detachable cap 2 provided at the opening of a milking bottle 1 for storing milk as shown in FIG. And a milking unit 3 provided on the upper part of the cap 2 and made of resin integrally with the cap 2. The cap 2 is detachable from the milking bottle 1. The inner wall of the milking unit 3 is provided with a detachable adapter 30 for improving the suction force by making the contact with the areola part of the breast dense.

[0003] A compressor section 4 for connecting the inside of the milking bottle 1 to a negative pressure is connected to a side surface of the cap 2 described above.
The compressor part 4 has a bottom part 41 which abuts on the bottom part of the milking bottle 1 and supports the milking bottle 1, a grip part 42 for holding a breast pump, and an upper part 43 connected to the cap 2. The milking bottle 1 and the cap 2 and the compressor unit 4 are detachable.

In using such a breast pump, it is necessary to apply the above-mentioned squeezing section 3 to the breast and to operate the compressor section 4 to evacuate the air in the milking bottle 1 to a negative pressure and then return to the atmospheric pressure. Milk the breast milk from the breast by repeating.

However, the milking unit 3 of the breast pump having the above structure is basically made of resin, and has a drawback that milking efficiency is poor because milking is performed only by the suction force of the negative pressure.

For this reason, breast pumps in which the entire milking section 3 is made of an elastic body are also manufactured. According to such a breast pump, the milking unit 3 also repeatedly contracts and expands each time the negative pressure and the negative pressure release are repeated, so that a massage effect is also added and milking can be performed efficiently. There are advantages.

However, even in the breast pump having the milking part 3 made of an elastic material as described above, there is a disadvantage that the milking part cannot be efficiently milked because the shape and structure of the milking part are simple. The present invention has been made in view of the above points, and an object of the present invention is to provide a breast pump capable of milking more efficiently than before.

[0008]

Means for Solving the Problems To solve the above problems, a breast pump according to the present invention is provided with a milking bottle for storing milk which has been milked, and is provided at an upper portion thereof and communicates with the milking bottle. In a breast pump having a milking unit made of an elastic body and a compressor unit that repeats suction and stoppage of air in the milking bottle, the milking unit includes a milking unit body formed in a funnel shape covering a breast and the milking unit. A nipple formed on the inner wall of the body, and a similarly funnel-shaped adapter that covers the areola part, wherein the thickness of the elastic body of the milking part body and the adapter is gradually reduced toward their distal ends. And

According to the present invention, in the milking section made of an elastic body, the thickness of the milking section main body and the adapter is gradually reduced toward the distal end, so that the foot portion of the breast and the outer periphery of the areola are in other portions. In comparison, preferentially and more strongly, compression will be released, and further from the foot of the breast to the tip, from the outer circumference of the areola toward the nipple, will be compressed sequentially, efficiently Be able to milk.

[0010]

FIG. 1 is a partial cross-sectional view of an embodiment of the present invention. As is clear from FIG.
It has a cap 2 provided at the opening of a milking bottle 1 for storing breast milk. The cap 2 has a hook-like hollow section for detachably attaching an elastic milking unit 3. A suction tube 21 is formed. This suction tube 21 communicates with the inside of the cap.

The cap 2 is provided with a funnel-shaped cover 22 made of, for example, resin. The funnel-shaped cover 22 covers the outside of the milking unit 3 and is made of an elastic milking unit 3. Is designed to protect. The cover 22 does not communicate with the inside of the milking bottle 1.

The milking part 3 made of an elastic body has a funnel-shaped adapter 32 like the funnel-shaped milking part main body 31, and the milking part main body 31 and the base part 33 of the adapter 32 are integrated. The suction tube 21 is detachably fitted to the suction tube 21. The thickness of the milking unit main body 31 is gradually reduced from the main body base portion 34 to the main body front end portion 35, and the thickness of the adapter 32 is similarly gradually reduced from the adapter base portion 36 to the adapter front end portion 37. Is configured. The length L of the adapter tip 37 from the adapter root 36 is preferably 60 to 70 m.
m is good. The adapter tip 37 preferably stimulates the ductal sinus preferentially, as will be apparent from the description of operation below. This is because when the length L is in the range of 60 to 70 mm, the adapter tip 37 comes into contact with the vicinity of the milk duct sinus.

When the breast pump according to the present invention is operated, the breast is brought into contact with the breast part 31 so that the nipple fits into the adapter 32 described above. At this time, the main body distal end 35 of the milking unit main body 31 contacts the foot of the breast, while the adapter 3
The adapter end 37 of the second abuts near the boundary between the areola and the breast (ductal sinus). When the compressor unit 4 is operated in such a state, the air in the milking bottle 1 is exhausted,
Negative pressure. As described above, when the inside of the milking bottle 1 becomes a negative pressure, the milking unit 3 is sucked and contracts. At this time, the main body distal end 35 of the milking unit main body 31
Due to its small thickness, it preferentially contracts and tightly tightens the foot of the breast. Furthermore, this contraction force gradually decreases in the direction of the breast tip, so that the entire breast is tightly covered with the milking unit main body 31, so that the suction effect by the negative pressure increases, and from the foot to the breast tip. You will be able to squeeze effectively.

On the other hand, the adapter distal end portion 37 is configured to come into contact with the vicinity of the boundary between the areola and the breast (milk duct sinus).
7 to the adapter base portion 36 to be contracted and pressed sequentially. It is known that when the boundary between the areola and the breast (ductal sinus) is stimulated, milk is increased, and in combination with the successive pressing from the adapter distal end portion 37 to the adapter root portion 36, milking can be effectively performed. Become.

After the negative pressure is applied for a predetermined time, the intake pipe (not shown) is opened to return the inside of the milking bottle 1 to the atmospheric pressure. At this time,
Since the milking section 3 is released from the negative pressure, the milking section 3 returns to its original state due to its elasticity.

As described above, by sequentially repeating the negative pressure and the atmospheric pressure, the breast, the areola and the nipple are repeatedly compressed and returned to the original state, so that the milking can be effectively performed.

[0017]

As described above, according to the breast pump of the present invention, in the breast part made of an elastic body, the thickness of the breast part main body and the adapter is gradually reduced toward the distal end, so that the foot part of the breast is obtained. And the outer circumference of the areola will be preferentially and more strongly compressed and released than the other parts, and further from the foot of the breast to the tip,
Since the squeeze is sequentially pressed from the outer periphery of the areola toward the nipple, milking can be performed efficiently.
