Description

Hand-free breast pump

The present invention relates to a milking machine, and more particularly to a hand-free milking device that is worn on the mother's breast so as to be freely milked without being supported by hands.

A pregnant woman will have breast filling during pregnancy, and breast milk will experience a change from colostrum to mature milk within one week after delivery, and the amount of breast milk will gradually decrease within three to five days. If the mother's breast (ie, the pregnant woman after childbirth) is not fed by her baby, her breasts will become hard and hot with pain, and may even cause swelling of the breast. In order to avoid swelling of the breasts of pregnant women, the number of breastfeedings should be 8 to 12 times a day. If breastfeeding is not carried out at an appropriate time, breast milk should also be forcibly discharged from the breasts of pregnant women. In order to force the discharge of breast milk in the breast, a milker (or a milking machine) is a commonly used tool.

In general, a milking device is a device for forcibly discharging colostrum manufactured after delivery or discharging breast milk remaining after breastfeeding. The milking machine can be divided into two types according to the manner of milking, one is a manual milking machine that discharges breast milk by pressing a vacuum ball which is sucked into a tubular shape, and the other is an automatic milking machine which discharges breast milk by using an electric pump. in In the manual milking machine, the vacuum ball is periodically pressurized by the mother's hand, and a funnel-shaped adsorption unit contacts the mother's breast and is supported by the mother's other hand so that the breast milk can be discharged from the mother's breast. . However, the amount of breast milk discharged by the manual milker is relatively small, and the mother needs to exert a lot of effort to press the vacuum ball to discharge the breast milk from the breast. Therefore, automatic breast milkers have recently been widely used.

However, as with the manual milking machine, it is inconvenient that the automatic milking device still needs to hold the funnel-shaped adsorption unit with one hand when using it, so that the mother cannot do other things while using it. In addition, whether the manual milking machine or the automatic milking device is used, the mother's body is exposed, so the mother can only use it at home or in a specific place, and cannot be used elsewhere. Therefore, manual milkers and automatic milkers have many limitations in their use time and field.

In order to solve the above problems, a number of different configurations of hand-free breast milk-free patent documents have been proposed, by coupling a hands-free milking device to a bra, so that the mother can use the wearing method to freely milk, and Do not use one hand to support the milking device, such as Korean Patent Document Registration No. 100947668 (registered on March 8, 2010), Korean Patent Registration Document No. 101333536 (registered on March 21, 2013), US Patent No. 8137153 No. (announced on March 20, 2012), US Patent No. 8307453 (announced on November 13, 2012), US Patent No. 6764377 (announced on July 20, 2004), US Patent No. 8192247 (announcement) Patent document dated June 5, 2012) and U.S. Patent No. 8,500,679 (published on August 6, 2013).

However, prior art hand-free milkers are required It must include a strap structure or a bra-type structure to allow the mother to contact the mother's breast during breastfeeding, thereby increasing the volume of the hand-free breast pump. Some hands-free breasters require a specific bra or clothing, which increases the cost of purchasing a hand-free breast pump. In addition, some hands-free breast presses are perforated in the bra so that the suction unit can contact the mother's breast, while a breast milk container of the hand-free milking device is placed outside the bra, so that the amount of breast milk discharged from the breast increases. The breast milk container will tip forward. Therefore, when the breast milk in the breast milk container reaches a certain amount, it is still necessary to support the hand-free milking device by the mother's hand, which causes inconvenience in use.

On the other hand, other hands-free milking machines of the prior art are disclosed in U.S. Patent No. 8,702,646 (issued on April 22, 2014) and Korean Patent Application No. 1020110009666 (announced on January 28, 2011) In the patent document, the hand-free milking device is disposed inside the mother's bra, eliminating the prior art bra-type fixing structure, thereby reducing the manufacturing cost and solving the above-mentioned inconvenient use problem. However, in the above-mentioned U.S. Patent No. 8,702,646, the hand-free milking device requires an additional adhesive material to allow the adsorption unit to contact the mother's breast, thereby increasing the manufacturing cost; In the patent document No. 1020110009666, the adsorption force of the hand-free breast pump to the breast is weak. Therefore, the hand-free breast pump described above is still inconvenient to use.

The first coupling portion 122 extends downward from the extending portion 121 in a vertical direction perpendicular to the extending portion 121, thereby being coupled thereto. The recirculation unit 13 and the storage container 14 are disposed, and have a third suction hole 122a. The third suction hole 122a is formed at the bottom of the inner circumferential surface of the first coupling portion 122, thereby vertically aligning the second suction hole 121a. It is used to communicate with the second suction holes 121a.

Further, as shown in the second figure, the suction chamber 12 includes a connecting portion 123 for connecting the extending portion 121 and the first coupling portion 122. The connecting portion 123 is a duct for vertically connecting the second suction hole 121a and the third suction hole 122a to each other. In the present embodiment, the inner diameter of the coupling portion 123 is smaller than the inner diameter of the third suction hole 122a and is equal to the inner diameter of the second suction hole 121a.

On the other hand, the extension portion 121, the first coupling portion 122, and the coupling portion 123 integrally constitute the suction chamber 12 by injection molding (or secondary injection molding) of a single mold. In addition, the extension portion 121, the first coupling portion 122 and the coupling portion 123 can be independently manufactured by injection molding, and by means of locking.

As shown in the second and third figures, the reflow preventing sheet 132 is made of a relatively thin sheet-like structure made of a material such as tantalum, and is used to isolate the space between the storage container 14 and the suction chamber 12. Or according to the operation of the electric pump 1 to form a closed state. For example, if a suction force generated by the electric pump 1 prevents the reflowing sheets 132 from coming into close contact with each other, the space between the storage container 14 and the suction chamber 12 is isolated; If the hands-free breast pump is in a compressed state (i.e., a non-suction state), the closed state is formed to transfer the breast milk to the storage container 14.

The storage container 14 is a breast bottle for storing the breast milk extruded from the mother's breast and is locked to the second coupling member 122-2 of the first coupling portion 122 along the upper periphery thereof. If the stored breast milk fills the storage container 14, the storage container 14 can be operatively separated from the suction chamber 12 and stored in a specific place.

Thus, the calibration groove 121-2 is semicircular or semi-elliptical. In the above case, calibration The piece 113 is detachably coupled to the calibration groove 121-2 such that the suction chamber 12 is non-rotatably fixed to the suction tube 112.

The fourth figure shows a side view of the hands-free breast pump of the first figure, and the fifth figure shows the side view of the first hand-free hand-held milker fixed to the bra.

Referring to the fourth and fifth figures, the hand-free milking device 10 provided by the present invention comprises an adsorption unit 11, a suction chamber 12, a recirculation preventing unit 13 and a storage container 14, and the adsorption unit 11 and the suction chamber. 12. The reflow unit 13 and the storage container 14 are prevented from being sequentially coupled. In the present embodiment, the suction chamber 12 is disposed in a vertical direction perpendicular to the adsorption surface 111 of the adsorption unit 11, and the storage container 14 is disposed in a parallel direction parallel to the adsorption surface 111. That is, the overall structure from the adsorption unit 11 to the storage container 14 is substantially in the shape of a "┐", so that the hand-free milking device 10 is stably in contact with the mother's breast and is fixed to the breast by the bra 30. .

Compared with the hands-free milking device of the prior art, the coupling structure between the adsorption unit and the storage container does not have a "┐" shape, so the inclination is a fixed angle of about 45 degrees, so that the prior art is free. When the hand-held milking device is fixed to the breast via the bra, the suction unit and the storage container are curved so as not to be stably supported by the bra. In contrast, the hand-held milking device 10 provided by the present invention has a "┐" shape from the adsorption unit 11 to the storage container 14, and the outer diameter of the connecting portion 123 is smaller than the extension portion 121 and the first coupling. The portion 122 is formed to form a neck portion of the hand-free breast pump 10 so that the lower end portion of the bra 30 is inserted into the joint portion 123, so that the hand-free breast pump 10 can be stably fixed.

Referring to FIG. 2, FIG. 6 and FIG. 7 together, if the electric pump 1 is operated to change the interior of the suction chamber 12 to a vacuum state or a pneumatic state, the electric pump 1 is inserted into the suction chamber 12. The adsorption unit 11 is compressed so that the breast B is expelled by the adsorption unit 11 to discharge the breast milk. Thereafter, the mother milk discharged from the breast B flows through the first suction hole 112a and the second suction hole 121a of the suction cylinder 112, and is discharged to the storage container 14 via the backflow prevention unit 13.

That is, the suction generated by the electric pump 1 is sequentially transmitted to the suction line 2, the suction chamber 12, the adsorption unit 11 and the breast B, and the breast B is periodically stimulated to perform the milking operation. At this time, the pair of backflow stop units 13 prevent the reflowing sheets 132 from being closely fitted to each other to isolate the space between the suction chamber 12 and the storage container 14, so that the breast milk discharged from the breast B is temporarily collected in the adsorption unit 11 And preventing the space above the reflow sheet 132. In the above state, if the suction force disappears and the electric pump 1 is operated to generate a compressive force, the paired prevention reflow flaps 132 are separated from each other by the compressive force, so that the pressurized extruded breast milk can be discharged to the storage. The inside of the container 14 is stored.

On the other hand, according to the present invention, the electric pump 1 includes a display screen 1-1, a plurality of control buttons 1-2 and a controller (not shown). Preferably, the electric pump 1 further includes a status indicator light for The operating state of the electric pump 1 is displayed.

In addition, the display screen 1-1 can also display a vacuum pressure, a breast milk temperature measured by an independent temperature sensor (disposed in a storage container or a suction line) and the like.

The plurality of control buttons 1-2 includes a power button, a stop button, a vacuum pressure control button for controlling the magnitude of the vacuum pressure, a milking operation time control button for controlling the milking operation time, and a milking operation time setting. Button or a milking amount setting button.

The controller controls the operation of the electric pump 1 for the reaction of the plurality of control buttons 1-2 described above. For example, the controller calculates the amount of breast milk that is pressurized and extruded based on the milking operation time and the vacuum pressure strength, and displays the calculation result on the display screen 1-1. Preferably, the controller can display the temperature sensed by the temperature sensor on the display screen 1-1.
