Description

  The present invention relates to a breast pump that squeezes breast milk.

  Conventionally, various breast pumps used by mothers for milking have been devised.

  For example, in Patent Document 1, a funnel portion (cup portion) for contacting the breast and a pump (negative pressure forming portion) that generates a negative pressure in a closed space formed by contacting the breast to the cup portion. ). In the breast pump of Patent Document 1, the closed space and the pump are connected so as to allow ventilation.

  In the breast pump of Patent Document 1, breast milk sucked into a closed space is stored in a baby bottle via a flow path.

Special table 2013-533428 gazette

  However, the breast pump of Patent Document 1 cannot be breast feeding unless the baby bottle is removed from the breast pump after milking and the artificial nipple is attached to the baby bottle when breast feeding.

  Therefore, the conventional milking machine including the milking machine of patent document 1 cannot perform milking and breast feeding simultaneously.

  An object of the present invention is to provide a breast pump capable of simultaneously performing milking and breast feeding.

The breast pump of the present invention has a cup part for contacting the breast,
A first flow path communicating with a closed space formed by contacting the cup with the breast, the first flow path having a first storage section in the middle for storing breast milk from the breast;
A negative pressure generating unit that has a suction port communicating with the first flow path, sucks air in the closed space from the suction port, and generates a negative pressure in the closed space;
A second flow path communicating with the first storage section and having an artificial nipple at the end opposite to the first storage section;
A first check valve that is provided in the middle of the second flow path and prevents fluid from flowing from the second flow path to the first storage unit.

  In this configuration, when milking and breastfeeding are started, the mother attaches the cup part to the breast and drives the negative pressure generating part. And the mother feeds the artificial nipple to the baby. The negative pressure generating unit is, for example, a pump.

  As a result, the air in the closed space is sucked into the first flow path, the negative pressure is generated in the closed space, and the breast milk from the breast is sucked into the first flow path and stored in the first storage unit. At this time, when the baby sucks the artificial nipple, the mother's milk stored in the first storage unit flows into the baby's mouth from the second channel through the artificial nipple. This allows the baby to drink breast milk. The first check valve can prevent fluid from flowing from the second flow path to the first storage unit.

  Therefore, according to the present invention, milking and breast feeding can be performed simultaneously.

  Moreover, it is preferable that the 2nd flow path has the 2nd storage part which stores the breast milk which flowed in via the 1st check valve from the 1st storage part in the middle.

  In this configuration, the second storage unit functions as a buffer region. More specifically, when the baby sucks the artificial nipple, the breast milk that has flowed from the first storage section through the first check valve is once stored in the second storage section. Thereafter, the breast milk stored in the second storage part flows into the baby's mouth from the second channel through the artificial nipple.

  Moreover, it is preferable that it is formed with the wound tube between the 1st storage part and the 2nd storage part in a 2nd flow path.

  In this configuration, even when the baby swings around the face, the tube extends, so that the tube is not blocked or pulled. Therefore, according to this configuration, constant feeding is possible.

  Moreover, it is preferable that it is formed with the wound tube between the artificial nipple and the 2nd storage part in a 2nd flow path.

  In this configuration, even when the baby swings around the face, the tube extends, so that the tube is not blocked or pulled. Therefore, according to this configuration, constant feeding is possible.

  Moreover, it is preferable to provide between the cup part and 1st storage part in a 1st flow path, and to provide the 2nd check valve which prevents a fluid from flowing from a 1st storage part to a cup part.

  In this configuration, the second check valve can prevent breast milk from flowing from the first storage portion to the cup portion.

  Moreover, it is preferable to provide an opening / closing valve that is provided between the first storage unit and the negative pressure generation unit in the first flow path and opens and closes the flow path therebetween.

  In this configuration, the mother closes the on-off valve when the baby sucks weakly during breastfeeding. Then, for example, the mother compresses the first storage unit, and causes the breast milk stored in the first storage unit to flow out to the second flow path via the first check valve.

  Moreover, it is preferable that a 2nd flow path has the several edge part branched and extended from a 2nd storage part, and the artificial nipple is provided in each edge part.

  In this configuration, each of a plurality of babies can feed a plurality of babies simultaneously by giving an artificial nipple.

  Moreover, it is preferable that a negative pressure production | generation part has a piezoelectric element, and drives with a piezoelectric element.

  In this configuration, the breast pump can be quieted by using a piezoelectric element that generates a small amount of sound and vibration during driving as a driving source.

  According to the present invention, milking and breastfeeding can be performed simultaneously.

  The piezoelectric pump 30 corresponds to the negative pressure generating unit of the present invention. The 1st container 11 is corresponded to the 1st storage part of this invention. The second container 21 corresponds to the second storage unit of the present invention.

  The cup portion 1 is for contacting the breast 50. The cup part 1 is in contact with the breast 50, thereby forming a closed space 51 between the breast 50 and the cup part 1.

  The first flow path 10 is formed by a space in the tube 2, a space in the first container 11, a space in the tube 3, and a space sandwiched between the piezoelectric pump 30 and the mounting portion 35. The first flow path 10 communicates with the closed space 51. The first flow path 10 has a first container 11 in the middle. The 1st container 11 isolate | separates the breast milk and air which flowed in from the tube 2 with a filter etc., and stores breast milk.

  The piezoelectric pump 30 has a piezoelectric element and is driven by the piezoelectric element. The mounting part 35 is mounted on the piezoelectric pump 30. The piezoelectric pump 30 has a substantially cylindrical shape, and the mounting portion 35 has a cup shape. The piezoelectric pump 30 has an air suction port 31 and an air discharge port 32. The suction port 31 of the piezoelectric pump 30 communicates with the first flow path 10. The piezoelectric pump 30 sucks air in the closed space 51 from the suction port 31 and generates a negative pressure in the closed space 51. Thereby, breast milk comes out of the breast 50.

  The second flow path 20 is formed by the space in the tube 4, the space in the second container 21, and the space in the tube 5. The second flow path 20 communicates with the space in the first container 11. The second flow path 20 has an end portion (end portion of the tube 5) opposite to the first container 11. An artificial nipple 9 is provided at the end opposite to the first container 11 (the end of the tube 5).

  The first check valve V <b> 1 is provided in the tube 4 in the middle of the second flow path 20. The first check valve V <b> 1 prevents fluid from flowing from the second flow path 20 to the first container 11.

  The second flow path 20 has a second container 21 that stores the milk that has flowed from the first container 11 through the tube 4 in the middle.

  In addition, the material of the tubes 2-5, the mounting part 35, the 1st container 11, and the 2nd container 21 is a polypropylene, polyethylene, etc., for example.

  The second check valve V <b> 2 is provided in the tube 2 that is between the cup portion 1 and the first container 11 in the first flow path 10. The second check valve V <b> 2 prevents the fluid from flowing from the first container 11 to the cup portion 1.

  The on-off valve C is provided in the tube 3 between the first container 11 and the piezoelectric pump 30 in the first flow path 10 and opens and closes the flow path in the tube 3.

  Hereinafter, the scene where the breast pump 100 performs milking and breast feeding simultaneously will be described.

  FIG. 2 is an explanatory diagram showing the flow of breast milk when the milking machine 100 shown in FIG. 1 is performing only milking. FIG. 3 is an explanatory diagram showing the flow of breast milk when the breast pump 100 shown in FIG. 1 is performing milking and breast feeding simultaneously. FIG. 4 is an explanatory diagram showing the flow of breast milk when the breast pump 100 shown in FIG. 1 is only breastfeeding.

  In addition, the arrow in a figure shows the flow of the fluid containing breast milk and air. The first check valve V1 and the second check valve V2 are indicated by ◯ and V. ○ and V are separated from each other, indicating that the valve is open. On the contrary, when ◯ and V are in contact, it indicates that the valve is closed.

  When milking and breastfeeding are started, the mother opens the on-off valve C, attaches the cup 1 to the breast 50, and drives (turns on) the piezoelectric pump 30. As a result, as shown in FIG. 2, the air in the closed space 51 is sucked into the first flow path 10, and the closed space 51 becomes negative pressure, and the breast milk is sucked into the first flow path 10 and the first container 11. Will be stored. Then, the mother feeds the artificial nipple 9 to the baby B.

  At this time, when the baby B sucks the artificial nipple 9, as shown in FIG. 3, the first check valve V <b> 1 opens, and the breast milk stored in the first container 11 is temporarily passed through the tube 4 to the second container. It flows into 21 and is stored in the second container 21. Thereafter, the breast milk stored in the second container 21 flows into the mouth of the baby B from the second flow path 20 through the artificial nipple 9. Thereby, the baby B can drink breast milk. The second container 21 functions as a buffer area.

The first check valve V <b> 1 prevents the fluid from flowing from the second flow path 20 to the first container 11. The second check valve V <b> 2 prevents breast milk from flowing from the first container 11 to the cup part 1.
If the first check valve V1 is not provided, air flows from the artificial nipple 9 into the first container 11 and the second container 21, so that the first check valve V1 is compared with the first check valve V1. The container 11 is unlikely to become negative pressure. Therefore, milking may not be possible.

  Therefore, according to the breast pump 100, milking and breast feeding can be performed simultaneously.

  In addition, since the piezoelectric pump 30 uses a piezoelectric element that generates less noise and vibration during driving as a driving source, the breast pump 100 can be quieted.

  In addition, the baby B's sucking power may be weak during breastfeeding due to individual differences of the baby B and the like. The mother closes the on-off valve C when the sucking force of the baby B is weak during breastfeeding. At this time, the on-off valve C may be closed and the piezoelectric pump 30 may be stopped (turned off), or the piezoelectric pump 30 may be left driven.

  Then, as shown in FIG. 4, the mother compresses the first container 11 and causes the milk stored in the first container 11 to flow out to the second container 21 via the first check valve V1. At this time, the second check valve V <b> 2 prevents the milk from flowing from the first container 11 to the cup portion 1.

  Thereafter, the baby B sucks the artificial nipple 9 so that the breast milk stored in the second container 21 flows into the mouth of the baby B from the second flow path 20 through the artificial nipple 9. Thereby, the baby B can drink breast milk.
