Description

Technical Field

[0001] The invention relates to the technical field of medical care equipment and supplies, in particular to a bionic breast pump. Background Art

[0002] Milk stasis often occurs repeatedly during the lactation period. If the stagnant milk is not discharged in time, it may cause secondary infection and induce acute mastitis, which not only affects breastfeeding but also brings great pain to women. Timely discharge of milk accumulation can effectively prevent the occurrence of acute mastitis. At present, the main ways to discharge milk accumulation are through breast pumping and manual milk discharge.

[0003] Currently, breast pumps on the market rely mainly on negative air pressure to express milk. Although it is simple and quick, the negative pressure it generates has a greater irritation to the nipple and areola. Long-term and repeated use can cause nipple pain, ulceration, changes in areola shape, etc. Moreover, it is less effective for patients with long-term milk accumulation and blocked milk ducts.

[0004] In order to solve the problems existing in milk discharge using the existing breast pump, it is necessary to develop a new bionic breast pump. Summary of the invention

[0038] As a preferred structure, a power supply 16 and a control board are installed in the lower cavity 4-2 of the shell 4, and the power supply 16 and the motor 5, the power supply 16 and the control board, and the control board and the motor 5 are respectively connected by wires; a switch key 14 and a speed knob 15 are arranged on the outside of the shell 4, and the switch key 14 and the speed knob 15 are respectively connected to the control board wires; the switch key 14 and the speed knob realize control of the motor 5 under the action of the control board.

[0039] The power supply 16 is installed in the housing 4, which expands the use locations and conditions of this embodiment, and will not be unused due to the absence of the external power supply 16. The main function of the control panel is to control the start and stop of the motor 5 and the size of the speed according to the input signal (such as the signal input through the switch key 14 and the speed knob), so as to adjust and control the movement speed of the jaw block 7. Therefore, the movement speed of the jaw block 7 can be adjusted according to the specific situation to achieve a reasonable matching of the milk discharge speed.

[0040] As a preferred structure, a first connecting portion 1 - 1 for connecting to the jaw block 7 is provided on the outer wall of the milk collecting shield 1 , and a second connecting portion 7 - 1 connected to the first connecting portion 1 - 1 is provided on the jaw block 7 .

[0041] The jaw block 7 and the milk collecting shield 1 are connected through the first connection and the second connection part 7-1, which effectively prevents the milk collecting shield 1 from being separated from the upper cavity 4-1 or failing to automatically restore its shape as the jaw block 7 returns after moving upward.

[0042] As a preferred structure, the jaw block 7 is a block-shaped body formed by three side surfaces connected end to end in sequence, and the three side surfaces are respectively a side plane 7-2, an arc surface 7-3 and a bionic curved surface 7-4; a first hinge hole 7-5 is arranged at the virtual axis of the arc surface 7-3, and the first connecting shaft 8 is hinged at the first hinge hole 7-5; a notch 7-6 is arranged at the junction of the side plane 7-2 and the arc surface 7-3, and the two side surfaces of the notch 7-6 are respectively fixedly connected to the two ends of the second connecting shaft 9, and the bottom surface of the notch 7-6 is an arc surface 7-3 arranged coaxially with the second connecting shaft 9.

[0043] The bionic curved surface 7 - 4 simulates the shape of a baby's lower jaw, and the jaw block 7 is manufactured by 3D printing.

[0044] The preferred structure of the first connection part 1-1 and the second connection part 7-1 in this embodiment is: the first connection part 1-1 arranged on the outer wall of the milk collection cover 1 is an L-shaped card plate, one end of which is vertically fixedly connected to the outer wall of the milk collection cover 1, and the other end of the L-shaped card plate is a free end, and the free end is arranged along the outer wall of the milk collection cover 1 from the large mouth to the small mouth; the second connection part 7-1 on the jaw block 7 is located on the arc surface 7-3 of the jaw block 7 and close to the junction of the arc surface 7-3 and the bionic surface; the second connection part 7-1 is a rectangular groove matched with the free end of the L-shaped card plate; the free end of the first connection part 1-1 of the milk collection cover 1 is inserted into the second connection part 7-1 of the jaw block 7.

[0045] Such a movable plug-in structure can not only ensure the linkage between the milk collecting cover 1 and the jaw block 7, but also facilitate the disassembly, assembly and cleaning of the milk collecting cover 1.

[0046] As a preferred structure, a one-way valve 13 is provided on the connecting tube of the milk collecting shield 1 , and the installation direction of the one-way valve 13 is from the small opening end of the milk collecting shield 1 to the connecting end of the connecting tube and the milk discharge tube 2 .

[0049] This greatly facilitates assembly and production, and also facilitates replacement and maintenance of parts inside the lower cavity 4-2.

[0050] The method for using the embodiment of the present invention to discharge milk from a patient:

[0051] In the first step, the milk collecting shield 1 is placed into the upper cavity 4-1 of the housing 4, and the milk collecting shield 1 is connected to the jaw block 7 through the first connecting portion 1-1 and the second connecting portion 7-1.

[0052] In the second step, the connecting tube at the small opening of the milk collecting shield 1 extends from one side of the upper cavity 4 - 1 of the shell and is connected to the milk discharge duct 2 , and the nipple and areola of the patient are placed in the milk collecting shield 1 .

[0053] In the third step, the motor 5 is started by the switch 14, and the motor 5 drives the crankshaft 10 to rotate. The rotating crankshaft 10 pulls the connecting rod 6 to make the jaw block 7 simulate the movement of the baby's lower jaw to reciprocate up and down; when the jaw block 7 moves upward, the space inside the milk collection cover 1 is compressed, so that the one-way valve 13 at the connecting pipe of the milk collection cover 1 is opened to discharge air; when the jaw block 7 moves downward, the space inside the milk collection cover 1 is enlarged, so that the one-way valve 13 at the small opening of the milk collection cover 1 is closed, and negative pressure is formed in the milk collection cover 1 to attract milk to be discharged.

[0054] The fourth step is to collect the milk after use, separate it from the milk discharge tube 2 and take it out from the upper cavity 4-1, clean the milk collection cover 1, process the milk in the milk collection bottle 3, and then clean the milk collection bottle 3 and the milk discharge tube 2. After cleaning, put away the bionic milk ejector.

[0055] When the embodiment of the present invention is used, the reciprocating jaw block 7 massages the nipple and areola, which can not only relieve the discomfort caused by negative pressure, but also stimulate nerve reflexes, and can prompt the hypothalamus to secrete more prolactin, thereby further increasing the amount of milk.

[0056] The above is a detailed introduction to the bionic breast pump provided by the embodiment of the present invention. The description of this embodiment only helps to understand the method and core idea of ​​the present invention; at the same time, for those skilled in the art, according to the idea of ​​the present invention, there will be changes in the specific implementation method and application scope. In summary, this description should not be understood as limiting the present invention.
