Description

Milking device of mother's milk}

The present invention relates to a milking machine for squeezing breast milk from mothers of infants, and more particularly, to increase the milking amount without causing pain to the mother's breastfeeding part (breast), and part of breast milk during breast milking. The present invention relates to a breast milking machine which prevents leakage to the outside at the source and improves the convenience of use further by easily milking breast milk.

In general, the milking machine is used for the purpose of artificially squeezing the remaining breast milk or storing salty milk because the breastfeeding part feels very severe pain when the breastfeeding part of the breastfeeding infant is left or the infant does not breastfeed.

Such a milking machine is currently commercially available in various forms. Among them, a manual type of pumping by hand by a vacuum pump (dropper type) and squeezing breast milk, or an electric type equipped with an electric vacuum pumping means, is widely used.

The conventional configuration of the manual milking machine includes a suction tube in the form of a fallopian tube which is covered by the nursing unit, a vacuum pump in the form of a rubber ball that causes air pressure to be generated in the suction tube, and a baby bottle in which breast milk introduced into the suction tube is stored.

This manual milking machine is for milking breast milk while the user (mother) holds the suction tube with one hand and presses and releases the vacuum pump against the breast feeding part (chest) with the other hand. Less, it takes a lot of power due to milking is of course very inconvenient to use.

In addition, when the baby bottle falls due to carelessness during milking, a portion of the mother's milk inside the baby bottle is introduced into the vacuum pump, thereby hampering the pumping efficiency of the pump, as well as having an unsanitary problem.

The conventional configuration of the above-described electric milking machine includes a body in which a vacuum pumping means for generating a vacuum pressure is generated from a vacuum pumping member rotating according to the driving of a motor, and the suction tube is connected to one side of the body. It is mounted by screwing the baby bottle in which breast milk flowed into the suction tube is stored in the lower part of the body.

The electric milking machine presses the power supply button against the feeding part (chest) while the user (the mother) is holding the body, and operates the vacuum pump means inside the body to feed the breast milk introduced into the suction tube to the lower part of the body. It is milked on the body, but it is heavy because it is equipped with a body with a large number of parts, such as a driving motor and a vacuum pumping element, and a suction tube and a baby bottle connected to the surroundings based on the body, and a lot of users use it. This is what it takes.

In addition, during the operation of the milking machine by continuously vacuuming the air inside the milk is always fast to suck the pain, as well as the overall problem that the milking amount is significantly reduced.

Accordingly, the present invention has been made to solve the conventional problems, the object of which is to separate the weight of the electric vacuum pumping means for generating the air pressure required for milking from the light-weight milking mouth is fastened to the suction bottle and the bottle as a breast milk Reduces the power required for milking and relieves breastfeeding pain due to breast milking by improving milking periodically by vacuuming or releasing vacuum pumping air filled in the milking machine's space as a constant cycle. Of course, to reduce the cost of reducing the number of parts by simplifying the internal components, and to further improve the productivity by shortening the assembly process.

A is a milking machine, the milking machine (A) is a milking hole (100) for milking and storing breast milk in the mother's breast feeding unit (110), and the suction hole (106) in communication with the inner space of the milking hole A vacuum pumping means 200 which is connected to the tube 109 by a predetermined length, and periodically pumps the breast milk while vacuuming or releasing the vacuum pumping the air filled in the internal space of the milking hole as a repetitive cycle of a constant cycle; Piston driving means for substantially performing the pumping operation of the vacuum pumping means can be divided into 300.

The milking hole 100 of the illustrated embodiment is installed so that the suction tube 102, which is covered on the mother's breast feeding part (chest) 110 to be detachably attached to one side fitting tube 101, and the screw of the upper end of the bottle 107. The coupling part 103 screwed to the site is provided on the lower side, and is fitted into the breast milk discharge hole 104 formed on the bottom surface of the inner space divided by the diaphragm 105 so that the breast milk inside the baby bottle flows backward. It is composed of a non-return valve 108 to prevent.

Here, the non-return valve 108 is molded using a material such as silicon having excellent elasticity and good flexibility, and is formed in an inverted triangle shape that becomes narrower from the upper side to the lower side and becomes thinner toward the lower side.

In addition, the bottom surface (pointed area) is to cut in the form of a slit to selectively pass or close the fluid (air and breast milk), in particular the milking opening according to whether or not the intake and exhaust of air pressure generated from the vacuum pump means to be described later In addition to maintaining or releasing the vacuum in the interior space, the incision at the bottom is always tightly closed except when the milked milk is discharged into the bottle. It does not leak out through the prevention valve.

The vacuum pumping means 200 of the illustrated embodiment uses a household AC voltage of 220V using an adapter 202 for converting an AC voltage into a DC voltage, or selects a power source using a replacement battery 203 as necessary. A base plate 201 for fastening and mounting the usable power supply unit 204 as a fixing structure such as a bracket 205 is provided, and the first and second fixing rings 206 fixed to the base plate as bolts or pins. Cylinder 208 supported by 207).

In this case, the first fixing ring 206 is fixed to the base plate so as not to be attached or detached as a fixing means such as a pin. The first fixing ring 206 is based on the installation position of the cylinder, and the second fixing ring 207 is a base using a bolt. The cylinder can be detached as necessary by allowing the detachment from the plate to be free.

In addition, the cylinder 208 has an outer diameter tapered downward from one side coupled to the second fixing ring toward the second fixing ring toward the second fixing ring, so that the cylinder 208 may be firmly fixed without flowing as a wedge shape together with the second fixing ring. It can be.

In addition, the piston is provided inside the cylinder and slides to provide a piston 209 for vacuum pumping the air in the cylinder. The pressure regulating hole 210 penetrates horizontally from both sides in order to minimize the load generated during the piston pumping operation. In this case, a part of the compressed air inside the cylinder is leaked to the outside of the cylinder during the piston pumping operation to reduce the load caused by the pumping of the piston itself, thereby preventing wear of the friction surface of the piston and the cylinder and preventing breakage. .

In addition, one end is fixed to the annular groove 211 provided on the outer circumferential surface of the piston and the other end is fitted to the engaging portion of the cylinder and the first fixing ring to form a flexible sealing plate 212 to seal the space inside the cylinder. .

The piston driving means 300 of the illustrated embodiment is connected to the connector 305 is screwed to one side of the piston so as to be rotatable as a hinge, the other side is decelerating rotation through the drive motor 301 and the reduction unit 302 It is rotatably connected as a hinge on the eccentric position of the rotating disk 303 to reciprocally slide the piston in the cylinder by the eccentric distance for each eccentric rotation of the rotating disk to vacuum pump or release the vacuum pump. The piston rod 304 is comprised.

In the drawing, reference numeral 213 illustrates a button for protruding outside the case to turn on / off a driving motor driven by receiving power from a power supply unit or to adjust a rotation ratio of a driving motor in stages.

The operation of the present invention having the configuration as described above will be described in detail with reference to FIGS. 2 to 5.

When the button 213 is turned on in a state in which the adsorption pipe 102 of the milking opening 100 is in close contact with the feeding part (thigh) 110 as shown in FIG. 4, the AC power supply or the battery itself is supplied from the power supply part 204. The power inside is applied to the motor 301 of the piston drive means to drive the motor.

The rotational speed of the rotating drive motor 301 is decelerated at a low speed through the reduction unit 302 and then rotates the rotating disc 303 fixed to the driving shaft 302a of the reduction unit in place. The vacuum pumping force of the vacuum pumping means is appropriately adjusted according to the rotation speed.

When the rotating disk is rotated in place, the piston rod 304 hinged in one direction from the center of rotation of the disk is reciprocated in the lateral direction by an eccentric distance generated every one rotation of the rotating disk. Piston 209 rotatably connected as a piston rod and a connector 305 also reciprocally slides inside the cylinder 208.

Here, one end is fixed to the annular groove 211 formed on the outer circumferential surface of the piston and the other end is fixed to the coupling portion of the cylinder and the first fixing ring, and the flexible flexible sealing plate 212 flows along the sliding piston. By pumping the fluid (air) in the cylinder by the end generates a strong air pressure necessary for milking.

At this time, the piston 209 is formed with a pressure regulating hole 210 for circulating a part of the fluid inside the cylinder with the outside air, a part of the air pressure in the cylinder can be released to the outside to reduce the rod between the piston and the cylinder, To keep the movement smooth and smooth, and the desired sealing force can be obtained by using the flexible sealing plate without the piston and cylinder coming into close contact with each other. will be.

In this way, when a strong air pressure is generated from the vacuum pumping means 200, the air in the milking port as a tube 109 connected to the intake and exhaust hole 208a on one side of the cylinder and the intake and exhaust hole 106 on the milking port, and also vacuum pumps the fluid inside the cylinder. The milk of the breast feeding part 110 is milked from the suction tube 102 by the air pressure generated while being pumped in the same manner as in FIG.

The following description describes the specific operation of breast milking.

That is, when the air in the milking hole is sucked into the cylinder 208 as shown in FIG. 4 by the vacuum pumping means 200, the lower portion of the non-return valve 108 fastened to the breast milk discharge hole 104 of the bottom of the milking hole. The incision is closed by the air pressure exiting to prevent the loss of air pressure by blocking the residual air in the bottle 107 and the air in the upper side of the milking opening.

At this time, the breast milk sucked from the nursing part 110 by the powerful air pressure to be discharged is accumulated in the space around the suction tube and the non-return valve as well.

Thereafter, the compressed air inside the cylinder 208 is sucked into the space inside the milking hole again by the piston 209 and the sealing plate 212, as shown in FIG. Accordingly, while the lower cutout of the non-return valve 108 is opened, the accumulated breast milk is stored freely dropping in the bottle.

In addition, the sucked air is momentarily pushed on the lactation part in close contact with the adsorption tube 102, so that the milking process through the lactation part is stopped.

Thus, in milking the breastfeeding part, the air inside the milking port is vacuum-pumped and compressed or decompressed every time the rotary disc 303 rotates instead of continuously sucking the breastfeeding part. Repeated milking and the operation for the milking is stopped to prevent the nursing pain caused by milking, as well as to obtain a desired milking amount.

The present invention described as described above is a milking port for milking and storing breast milk in the mother's breastfeeding unit and vacuum pumping the air filled in the internal space of the milking hole as a repeated cycle of a constant cycle or releasing the compressed state. Lactation pain caused by breast milking by reducing the power required for breast milking by separating the means as tubes, and by milking the breast milk periodically while vacuuming or releasing vacuum pumping the air filled in the milking machine space as a repetitive cycle of a certain cycle. The milking amount is further improved.

In addition, it is possible to easily operate the button required for milking and to adjust the suction pressure, and also to provide various effects such that the productivity of assembly is improved due to the hygienic and simple structure because the mother milk stored inside the bottle does not leak out. It is.
