Description

Technical Field

[0001] The utility model relates to the technical field of breast pumps, in particular to an electric breast pump host suitable for bilateral use. Background Art

[0002] An electric breast pump is mainly composed of two parts. One part is the electric breast pump main body for generating gas negative pressure, and the other part is a milk suction terminal with a horn cover and a three-way pipe. The electric breast pump main body is connected to the milk suction terminal through a pipe. The horn cover is used to fit against the mother's chest. The electric breast pump main body provides negative pressure to the milk suction terminal, so that the milk suction terminal can be used for negative pressure milk suction from the mother's chest.

[0003] At present, the main electric breast pump for providing negative pressure to the milk suction terminals is mainly pumped by an air pump and supplies two milk suction terminals at the same time, so that the two milk suction terminals can be combined to suck milk from both sides of the mother's breasts at the same time. However, since one air pump is used to pump milk from both sides, there is a problem of insufficient pressure on both sides.

[0004] To this end, the Chinese utility model "Double-sided Breast Pump Host" with announcement number proposes a design of simultaneous pumping operations through multiple air pumps. The host body includes a shell with an internal space and a plurality of piezoelectric pumps arranged in the shell; all the piezoelectric pumps are arranged in series in sequence through pipelines; the overall air intake of the series-connected piezoelectric pumps is connected to the outside of the shell through a pipeline. By connecting a plurality of piezoelectric pumps in series, multiple piezoelectric pumps can work simultaneously to generate suction to meet the suction requirements of the breast pump.

[0005] However, the air pressure acting on both sides of the above-mentioned pumping method is basically the same, and the breasts of most mothers are not exactly the same. The milk swelling in one breast may be different from that in the other due to reasons such as sleeping on the side. If the milk suction pressure of the milk suction terminals on both sides is the same, the milk suction effect on the two breasts will inevitably be very different, which is not smart enough to use.

[0038] See also Figure 1-6 An electric breast pump host suitable for bilateral use includes a shell 1 on which a main controller 2, a first pressure system 3 and a second pressure system 4 are arranged.

[0039] The first pressure system 3 includes a first air pump 301 and a first air duct assembly 302 installed on the shell 1, the first air duct assembly 302 has a first internal connecting port 303 for communicating with the first air pump 301, and the first air duct assembly 302 has a first external connecting port 304.

[0040] The second pressure system 4 includes a second air pump 401 and a second air duct assembly 402 installed on the shell 1, the second air duct assembly 402 has a second internal connecting port 403 for communicating with the second air pump 401, and the second air duct assembly 402 has a second external connecting port 404. The second pressure system 4 also includes a second solenoid valve 405 installed on the shell 1 and arranged between the second internal connecting port 403 and the second external connecting port 404, and a second air pressure sensor 406 installed on the shell 1 for detecting the air pressure in the second air duct assembly 402.

[0041] The main controller 2 is electrically connected to the first air pump 301 , the first solenoid valve 305 , the first air pressure sensor 306 , the second air pump 401 , the second solenoid valve 405 , and the second air pressure sensor 306 .

[0042] Two breast pumping terminals are configured for bilateral breast pumping: one of the breast pumping terminals can be connected to the first external communication port 304 through a pipeline, so that the first pressure system 3 can pump pressure for the breast pumping terminal to enable negative pressure breast pumping; the other breast pumping terminal can be connected to the second external communication port 404 through a pipeline, so that the second pressure system 4 can pump pressure for the breast pumping terminal to enable negative pressure breast pumping.

[0043] When performing bilateral breast pumping, independent pressure supply is performed through the first pressure system 3 and the second pressure system 4, and corresponding air pressure detection is performed through the corresponding first air pressure sensor 306 and the second air pressure sensor 406, so that feedback can be provided for independent air pressure regulation, so that when performing bilateral breast pumping, the user can use an independent pressure system to pump milk on the corresponding side, which is smarter and safer to use.

[0044] In this embodiment, the electric breast pump host further includes an input module 5 disposed on the housing 1 for a user to input control information, and the input module 5 is electrically connected to the main controller 2 .

[0045] The user can input control information through the input module 5, such as inputting corresponding air pressure value or air pressure level, pumping time, single-side pumping (first side or second side, or corresponding to the left or right side of the human body), double-side pumping, etc. In some embodiments, the input module 5 includes a touch control screen.

[0046] After receiving the corresponding input control information, the main controller 2 controls the first air pump 301 and the second air pump 401 to work / turn off, increase power / reduce power, or controls / combines the control of the first solenoid valve 305 and the second solenoid valve 405 to be in the on state / closed state, or combines the air pressure signals obtained by the first air pressure sensor 306 and the second air pressure sensor 406 to make corresponding pressure changes, etc.

[0047] In this embodiment, the electric breast pump host further includes an information display module 6 disposed on the housing 1, and the information display module 6 is electrically connected to the main controller 2. The information display module 6 can be used to display corresponding information, such as remaining milk pumping time, current milk pumping pressure, milk pumping level, etc. In some embodiments, the information display module 6 includes a display screen or a digital tube.

[0048] In this embodiment, the electric breast pump host further includes a power module 7, which includes a power circuit and a battery 701 installed on the housing 1. The battery 701 is electrically connected to the main controller 2 via the power circuit, which is more convenient to use.

[0049] In this embodiment, the housing 1 has an installation cavity 101, the installation cavity 101 is installed with a noise reduction box 8, the first air pump 301 and the second air pump 401 are installed in the noise reduction box 8, and the noise reduction box 8 has a connecting hole suitable for the first air guide duct assembly 302 and the second air guide duct assembly 402 to pass through. The noise reduction box 8 is used to perform sound insulation noise reduction to reduce the noise impact on the user.

[0050] Furthermore, the first solenoid valve 305 and the second solenoid valve 405 are installed in the noise reduction box 8 .

[0051] The noise reduction box 8 includes a first partial box body 801 and a second partial box body 802 connected to the first partial box body 801; the connecting hole is arranged at the connection between the first partial box body 801 and the second partial box body 802, a part of the inner wall of the connecting hole is located on the first partial box body 801, and another part of the inner wall of the connecting hole is located on the second partial box body 802.

[0052] The first part of the box body 801 and / or the second part of the box body 802 are elastic boxes. In the case of sound insulation and noise reduction, the damage to the air pump caused by the electric breast pump host being hit by, for example, sliding is reduced. In some embodiments, the elastic box body is made of TPE material.

[0053] A detachable connection structure is provided between the first partial box body 801 and the second partial box body 802 .

[0054] The detachable connection structure includes a block 803 formed on the first part of the box body 801 and a slot 804 formed on the second part of the box body 802 and matched with the block 803. The first part of the box body 801 and the second part of the box body 802 are more convenient to join.

[0055] In this embodiment, the electric breast pump host further includes an additional pipeline 9, which is used to connect the first air guide pipeline assembly 302 and the second air guide pipeline assembly 402, and an additional solenoid valve 10 is provided on the additional pipeline 9.

[0056] At least one first solenoid valve 305 is provided between the first air pump 301 (or the first internal connection port) and the first external connection port 304 , and a first end solenoid valve 307 closest to the first external connection port 304 is formed on the route from the first air pump 301 to the first external connection port 304 .

[0057] On the route from the first air pump 301 to the first external connection port 304, the connection point between the additional pipeline 9 and the first air guide pipeline assembly 302 is located between the first air pump 301 and the first terminal solenoid valve 307, that is, the first terminal solenoid valve 307 forms a terminal conduction switch. When the main controller 2 controls the additional solenoid valve 10 to conduct the additional pipeline 9, the switch state of the first terminal solenoid valve 307 directly affects the pumping pressure of the first air pump 301 on the second air guide pipeline assembly 302. The sensing point of the first air pressure sensor 306 on the first air guide pipeline assembly 302 is located between the first internal connection port 303 and the first terminal solenoid valve 307.

[0058] In the case where the main controller 2 controls the additional solenoid valve 10 to connect the additional pipeline 9: when the main controller 2 controls the first terminal solenoid valve 307 to disconnect the first air pump 301 from the external breast pumping terminal, the first air pump 301 can pump the second air guide pipeline assembly 502 to perform additional pumping pressure on the second pressure system 4.

[0059] The second pressure system 4 also has a corresponding second end solenoid valve 407, and its setting position and function are similar to those of the first end solenoid valve mentioned above, which will not be described in detail here.

[0060] When the input module 5 is used to input the control of single-sided breast pumping, the main controller 2 first confirms the input breast pumping pressure or breast pumping level. When the input breast pumping pressure or breast pumping level exceeds the preset single-sided breast pumping protection threshold, for example, when it exceeds the negative pressure of 140 mmHg, the pressure system (such as the first pressure system) is additionally pumped by another pressure system (such as the second pressure system), and the air pump is better protected by the common pumping. When the input breast pumping pressure or breast pumping level does not exceed the preset single-sided breast pumping protection threshold, there is no need to perform additional pumping for the pressure system by another pressure system, so as to ensure the accuracy of pressure control as much as possible.

[0061] In this embodiment, before the additional pumping is performed, the main controller 2 also confirms whether the breast pumping side (the pressure system that needs to be additionally pumped) is already in working condition. When the breast pumping side is already in working condition, the main controller 2 first operates the other pressure system, and changes the air pressure in the air duct assembly of the other pressure system to the same as the air pressure in the air duct assembly of the pressure system that needs to be additionally pumped, or the air pressure difference is within a preset range, for example, the air pressure difference is within a negative pressure of 2 mmHg, and then controls the additional solenoid valve 10 to make the additional pipeline 9 conductive, and then the other pressure system performs additional pumping. It effectively avoids the influence of the sudden conduction of the additional pipeline 9 on the user's breast pumping when the air pressure difference is large, which is safer. When the breast pumping side is not in working condition, the additional solenoid valve 10 and the other pressure system can be controlled at the same time, so that the air pressure can reach the required level or corresponding air pressure value faster.

[0062] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.
