Description

  The present invention relates to a milking device and a method for controlling the milking device, for example, for a mother to milk milk.

When an infant or the like takes breast milk from a breast or nipple of a mother or the like, the following operation is performed.
That is, an infant or the like first places the tip of the mother's nipple in the sucking cavity in his / her mouth. In this state, the infant or the like places the tongue on the lower side of the nipple, raises the side surface of the tongue, closes the tongue to the nipple, and the tongue is disposed so as to wrap the nipple.

Next, the tip side of the tongue of an infant or the like rises and pushes the nipple with the tongue, and this movement gradually moves in a undulating manner toward the base side of the tongue.
In this process, the tongue performs a peristaltic movement (hereinafter referred to as “peristalsis-like movement”) in which a wave moves from the tip side to the root side, and the nipple is squeezed from the base toward the tip. The negative pressure in the closed space between the nipple, tongue and upper jaw increases. Then, when this closed space is opened, the pressure is released and breast milk comes out from the nipple. By swallowing the breast milk that came out, the nursing exercise is completed.

  In this way, when infants take breast milk, they perform peristaltic movements with their tongues, so it is important to reproduce the same behavior when milking breast milk etc. from the nipple with a breast pump, When breast milk is squeezed from a nipple, a breast pump is proposed in which the stimulation of the same peristaltic movement is applied to the nipple or the like (for example, Patent Document 1).

That is, when a mother or the like inserts his / her breast into a funnel-shaped milk receiving portion of a breast pump, the breast is in contact with a flexible portion made of silicone rubber formed on the surface of the milk receiving portion. Arranged stably in contact.
In addition, three rollers are arranged on the side of the flexible part opposite to the side where the breast is arranged so as to correspond from the root side to the tip side of the arranged nipple.
And these rollers are trying to reproduce "swing-like movement" by the infant's tongue by abutting while rotating sequentially from the root side to the tip side of the nipple.

Japanese Patent No. 4774374

By the way, as described above, the peristaltic movement by an infant or the like is performed in close contact so as to wrap the nipple with the tongue.
Then, in a conventional breast pump, when the roller is operated in a state in which the flexible part made of silicone rubber is arranged so as to seal the periphery of the nipple, and the peristaltic movement is performed, the roller is inserted into the nipple and the like via the flexible part. Therefore, the user feels pain or the like by being rubbed by the roller.
Furthermore, in order to take out breast milk from the nipple, the breast pump uses a suction pump to create a negative pressure in the atmosphere of the space formed by the breast and the milk receiving part, thereby sucking.
Therefore, there is a problem that when a roller is brought into contact with a nipple or the like disposed in a space sucked by a suction pump, the roller is rubbed to increase the pain and make it difficult to reproduce the peristaltic movement.
Furthermore, since the conventional milking machine was a comparatively large apparatus, there also existed a problem that it was unsuitable for personal use at home.

  Therefore, the present invention reduces the pain given to a user such as a mother during milking, enables the reproduction of the original peristaltic movement, and enables the use at home and the method for controlling the milking device The purpose is to provide.

  According to the present invention, the purpose of the present invention is to provide a negative pressure space for a breast placement portion for placing a breast portion such as a subject's breast and nipple, and at least a space between the breast portion and the breast placement portion. A plurality of pump parts, a plurality of pressure parts arranged at different locations from the base side to the tip side of the breast part, and controllable to a pressurized state or a non-pressurized state, so as to face the pressurizing part And a presser part that receives an influence on the breast part due to the pressurization of the pressurizing part, and the pressurizing part is capable of applying pressure to the outside by introducing the gas inside This is achieved by a milking device having a bag portion.

According to the above-described configuration, a plurality of pressurizing units are arranged at different locations from the base side to the distal end side of the breast unit, and can be controlled in a pressurized state or a non-pressurized state. The pressure part has a gas bag part that can apply pressure to the outside by introducing gas into the inside.
Therefore, since the pressurizing part for applying pressure to the breast part has a gas bag part such as a balloon, the user hardly feels pain even when pressure is applied to the breast part.
For this reason, even if the breast placement part and the breast part are brought into close contact like a peristaltic movement of an infant or the like and the pressure part applies pressure to the breast part, it is difficult for the user to feel pain etc. It is possible to reproduce a movement close to a peristaltic movement by the tongue of an infant or the like, and smoother milking is possible for the user. Moreover, since a milking apparatus can be reduced in size, it is also configured to be easily used at home.

  Preferably, the pressing portion has the gas bag portion.

  According to the above configuration, since the pressing portion has a gas bag portion such as a balloon, the breast portion is affected by the pressurization of the pressurizing portion on the opposite side of the breast portion that is pressurized by the pressurizing portion. It is possible to remarkably relieve the occurrence of pain or the like in the breast portion that is brought into contact with the holding portion to be received.

  Preferably, the gas bag portion of the pressing portion is configured to be controlled in a pressurized state or a non-pressurized state, and after the breast portion is arranged in the breast arranging portion, the pressing portion and the additional portion are added. A gas is introduced into the inside of the gas bag portion of the pressure portion to form a pressurized state.

  According to the above configuration, after the breast portion is placed in the breast placement portion, the user places the breast portion into the breast in order to introduce a gas into the gas bag portion of the pressing portion and the pressurizing portion to be in a pressurized state. Since the breast part is brought into close contact with the breast placement part by subsequent pressurization, it is possible to make the contact more reliably. For this reason, the operation | movement by the subsequent pressurization part can be approximated more like the actual peristalsis-like movement of infants.

  Preferably, the pressurizing unit has a plurality of gas bag portions, and a plurality of the gas bag portions are inflated in order, whereby pressure is applied in order from the breast side to the nipple side of the breast portion. It is characterized by becoming.

  According to the said structure, since a pressure is applied in order from the breast side (root side) of a breast part to a nipple side (tip side) by a pressurization part, it can be made to approximate more like a peristaltic movement of an infant. .

  According to the present invention, the purpose of the present invention is to provide a negative pressure space for a breast placement portion for placing a breast portion such as a subject's breast and nipple, and at least a space between the breast portion and the breast placement portion. A plurality of pump parts, a plurality of pressure parts arranged at different locations from the base side to the tip side of the breast part, and controllable to a pressurized state or a non-pressurized state, so as to face the pressurizing part And a holding part that receives an influence on the breast part due to the pressurization of the pressurizing part, and the pressurizing part introduces gas into the inside so that the gas bag part applies pressure to the outside. It is achieved by a method of controlling a milking device, characterized by adding.

  The present invention provides a milking device and a milking device control method that can reduce pain and the like given to a user such as a mother during milking, enable reproduction of the original peristaltic movement, and can also be used at home. There is an advantage that you can.

  As shown in FIG. 1, the peristaltic breast pump 1 according to the present embodiment can be downsized unlike conventional ones, so that it is easy to use at home by users such as mothers.

FIG. 5 is a schematic explanatory view showing a main operation example of the peristaltic breast pump 1 according to the present invention, and FIG. 6 is a schematic diagram showing a timing chart of a main operation example of the peristaltic breast pump 1.
In the present embodiment, an example in which a “peristaltic breast pump 1” shown in FIG. 1 is used for a mother to milk breast milk will be described below.

First, the mother inserts the breast or the like P from the insertion opening 21 of FIG. This state is shown by (1) in FIG. 5 and (1) in FIG.
As shown in FIG. 5A, at this time, the suction pump 110 and the pressurization pump 120 are not operating, and the contact balloon 70 and the like, the first peristaltic balloon 80, the second peristaltic balloon 81, and the third The peristaltic balloon 82 is in a deflated state.
For this reason, the mother can easily bring his / her breast P or the like into close contact with the close contact funnel 22 of the breast placement unit 20.

Next, the mother operates the switch 101 of the “milking pump / operation unit 100” in FIG. 1 to operate the peristaltic breast pump 1, and also operates the pressurization adjustment dial 103 and the suction adjustment dial 104, which is optimal for the self. Adjust to pressure.
Thus, in this embodiment, the mother who is a user can adjust the pressure of the pressurization pump 120 and the suction pump 110, which will be described later, to an optimal state, so that milking can be performed without feeling pain or the like. can do.

When the peristaltic breast pump 1 operates, first, the state shown in FIG. That is, the pressurization pump 120 of FIG. 4 operates, and only the contact balloon electromagnetic valve 132 is “ON”.
At this time, as shown in FIG. 6B, the first peristaltic balloon solenoid valve 133, the second peristaltic balloon solenoid valve 134, and the third peristaltic balloon solenoid valve 135 are “OFF”. Yes.

Then, as shown in FIG. 5 (2), the contact balloons 70 and 71 into which the air has been introduced are inflated, and the contact balloons 70 and 71 press the upper side of the breast part P through the contact funnel 22. Transforms into
As a result, the mother's breast P or the like is brought into close contact with the close contact funnel 22 of the breast placement portion 20 and is stably placed.

  Next, the process proceeds to the stage shown in FIG. In FIG. 5 (3), as shown in FIG. 6 (3), in a state where the contact balloons 70 and 71 are inflated, that is, in a state where a breast such as a breast P is in close contact with the breast placement portion 20, FIG. The first peristaltic balloon solenoid valve 133 is set to the “ON” state.

As a result, air is introduced into the first peristaltic balloon 80 disposed on the lower side of the breast P or the like in FIG. 5, and the first peristaltic balloon 80 is inflated.
That is, the breast P or the like is pressed by the inflated contact balloons 70 and 71 on the upper side and pressed (pressurized) by the first peristaltic balloon 80 inflated through the contact funnel 22 on the lower side. Is done. At this time, the part to be pressed is the base side of the breast P or the like.

Next, the process proceeds to FIG. In FIG. 5 (4), as shown in FIG. 6 (4), the second peristaltic balloon solenoid valve 134 of FIG. “ON” state.
Then, air is introduced into the second peristaltic balloon 81 arranged on the lower side of the breast P or the like in FIG. 5, and the second peristaltic balloon 81 is inflated.
Thereby, the breast P or the like is pressed by the inflated contact balloons 70 and 71 on the upper side, and on the lower side by the first peristaltic balloon 80 and the second peristaltic balloon 81 inflated. Is pressed (pressurized). At this time, the portion pressed by the second peristaltic balloon 81 is closer to the nipple side (tip side) than the first peristaltic balloon 80.

Next, the process proceeds to FIG. In FIG. 5 (5), as shown in FIG. 6 (6), the first peristaltic balloon solenoid valve 133 of FIG. 4 is moved in the state where the contact balloons 70 and 71 and the second peristaltic balloon 81 are inflated. “OFF” state.
Then, the introduction of air into the first peristaltic balloon 80 in FIG. 4 stops, and as shown in FIG. 5 (5), the first peristaltic balloon 80 is in a deflated state, and the pressure applied to the breast P or the like is reduced. Will be weakened.

  At this time, the part that presses the lower side of the breast P or the like moves to the arrangement part of the second peristaltic balloon 81 on the nipple side (tip side) from the first peristaltic balloon 80.

At the same time, as shown in (5) of FIG. 6, the suction pump 110 of FIG. 4 operates and the negative pressure solenoid valve 131 is turned on.
Thereby, air is sucked from the internal space of the negative pressure atmosphere holding unit 30 in FIG. 2, and air is also sucked from the internal space of the breast placement unit 20 communicating with the internal space of the negative pressure atmosphere holding unit 30. These spaces are in a negative pressure state.
At this time, the insertion port 21 of the breast placement unit 20 is closed by the mother's breast P or the like.

  In this negative pressure state, the nipple of the mother's breast P or the like is sucked, and the breast milk or the like that has come out of the nipple moves toward the small chamber 33 in FIG.

Next, the process proceeds to FIG. In FIG. 5 (6), which is an example of the movement from FIG. 5 (6) to (7), the contact balloons 70 and 71 and the second peristaltic balloon 81 are inflated as shown in FIG. 6 (6). In this state, the third peristaltic balloon solenoid valve 135 of FIG. 4 is set to the “ON” state.
Then, air is introduced into the third peristaltic balloon 82 disposed on the lower side of the breast P or the like in FIG. 5, and the third peristaltic balloon 82 is inflated.

  As a result, the breast P or the like is pressed by the inflated contact balloons 70 and 71 on the upper side, and on the lower side by the inflated second peristaltic balloon 81 and the third peristaltic balloon 82. Is pressed (pressurized). At this time, the portion pressed by the third peristaltic balloon 82 is the nipple side or the nipple portion from the second peristaltic balloon 81.

  Accordingly, the portion that presses the lower side of the breast P or the like includes not only the arrangement portion of the second peristaltic balloon 81 but also the arrangement portion of the third peristaltic balloon 82 that is the nipple side or the nipple portion from this portion. Become.

At the same time, the suction pump 110 of FIG. 4 operates and the negative pressure solenoid valve 131 maintains the “ON” state, whereby air is sucked from the internal space of the negative pressure atmosphere holding unit 30 of FIG. Then, air is also sucked from the internal space of the breast placement portion 20 that communicates with the internal space of the negative pressure atmosphere holding portion 30, and the negative pressure state is maintained in these spaces.
Therefore, in this negative pressure state, the nipple of the mother's breast P or the like is sucked, and the breast milk or the like discharged from the nipple moves toward the small chamber 33 in FIG.

Next, the process proceeds to FIG. 5 (7), as shown in FIG. 6 (7), the second peristaltic balloon electromagnetic valve 134 in FIG. “OFF” state.
Then, the introduction of air into the second peristaltic balloon 81 in FIG. 4 is stopped, and the second peristaltic balloon 81 is in a deflated state as shown in FIG. Will be weakened.

  At this time, the portion that presses the lower side of the breast P or the like is moved from the second peristaltic balloon 81 to the nipple side or the arrangement portion of the third peristaltic balloon 82 that is the nipple portion.

Thus, in the present embodiment, the first peristaltic balloon 80 to the third peristaltic balloon 82 sequentially press (pressurize) the lower side of the breast P or the like.
That is, pressure is applied in order from the breast portion side, which is the base side of the breast portion, to the nipple side, which is the distal end side.
This is the same movement as the above-described peristaltic movement performed by the infant.
Therefore, the mother can reproduce the same movement as when the baby is breastfeeding, and can milk the milk very naturally.

In the present embodiment, the mother's breast P or the like is pressed by the first peristaltic balloon 80 or the like made of silicone rubber and filled with air. Even if it presses in the state where the part 20 is closely_contact | adhered, it becomes the structure which is hard to make a mother feel pain.
Therefore, even if the baby actually reproduces the movement close to the state in which the tongue is in close contact with the mother's nipple and performs a peristaltic movement with the tongue, natural milking without pain or the like can be performed.

  In addition, the upper side supports the breasts P pressed by the “peristalsis-like movement” with respect to the lower side of the breasts P performed by the first peristaltic balloon 80, the second peristaltic balloon 81, and the third peristaltic balloon 82. Similarly, since the balloons 70 and 71 are balloons or the like that are inflated with air, even if the breasts P or the like are pressed with the contact balloons 70 and 71, it is difficult for the mother to feel pain or the like.

  As described above, since the upper side of the breast P or the like is pressed, the “peristaltic movement” on the lower side can be performed more effectively. In this respect, in the present embodiment, even if the upper side is firmly pressed by the contact balloons 70 and 71, the mother is not painful and the like, and the first peristaltic balloon 80 or the like is more effectively used. Can be reproduced.

Incidentally, in FIG. 5 (7), the operation of the suction pump 110 of FIG. 4 is simultaneously maintained, and the negative pressure solenoid valve 131 is maintained in the “ON” state.
Thereby, air is sucked from the internal space of the negative pressure atmosphere holding unit 30 in FIG. 2, and air is also sucked from the internal space of the breast placement unit 20 communicating with the internal space of the negative pressure atmosphere holding unit 30. These spaces are maintained in a negative pressure state.

  Further, since the suction force (negative pressure) becomes maximum between FIG. 5 (6) and FIG. 5 (8), the nipple of the mother's breast P or the like is sucked and removed from the nipple by this negative pressure state. The breast milk or the like moves toward the small chamber 33 in FIG.

Next, the process proceeds to FIG. In FIG. 5 (8), as shown in FIG. 6 (8), the third peristaltic balloon solenoid valve 135 of FIG. 4 is set to the “OFF” state with the contact balloon 70 inflated.
Then, the introduction of air into the third peristaltic balloon 82 in FIG. 4 stops, and the third peristaltic balloon 81 is in a deflated state as shown in FIG. 5 (8). At this time, all of the first peristaltic balloon 80 to the third peristaltic balloon 82 are deflated, and the pressure from these to the breast P or the like is weakened.

However, in FIG. 5 (8), at the same time, the operation of the suction pump 110 of FIG. 4 is maintained, and the negative pressure solenoid valve 131 is maintained in the “ON” state.
Thereby, air is also sucked from the internal spaces of the negative pressure atmosphere holding unit 30 and the breast placement unit 20 in FIG. 2, and the negative pressure state is maintained in these spaces, and milking of the breast milk is executed.

Next, the negative pressure solenoid valve 131 is turned “OFF”, and the negative pressure state in the internal space of the negative pressure atmosphere holding unit 30 and the breast placement unit 20 in FIG. 2 is released.
And the milking by a peristaltic movement is continued by repeating operation | movement of (3) to (8) of FIG. 5, and milking from mother's breasts P etc. is complete | finished after milking of a fixed amount.
Then, a certain amount of the breast milk 33 in FIG. 2 opens the check valve 33a portion by its own weight, and the breast milk is accumulated in the baby bottle 40 in FIG.

  The present invention is not limited to the above embodiment, and various modifications can be made without departing from the scope of the claims.
