Description

Technical Field

[0001] This invention belongs to the field of medical devices and provides a lactation device and its control method that combines dual-airbag compression with negative pressure suction. Background Technology

[0002] Currently, most breast pumps on the market use a single negative pressure suction method, which lacks effective pressure on the tissues surrounding the breast, and has limited effect on improving local milk stasis. Breastfeeding women often experience mastitis and other problems due to poor milk drainage.

[0003] Therefore, there is an urgent need for a breast pump with breast compression function to promote milk flow and help solve problems such as poor milk flow and mastitis caused by milk stasis. Summary of the Invention

[0004] The problem to be solved by this invention is to propose a lactation device and its control method that combines dual-airbag compression with negative pressure suction.

[0005] To achieve the above objectives, as a first aspect, the technical solution of the present invention provides a lactation unblocking device combining dual-airbag compression and negative pressure suction, comprising:

[0006] The main body of the dual-airbag breast shield includes a ring-shaped areola coverage area and a periphery of the breast contact area;

[0007] The ring-shaped airbag assembly is detachably positioned between the areola coverage area and the peripheral breast contact area, with its diameter gradually increasing from the areola coverage area to the peripheral breast contact area.

[0008] Gas injection structure, injecting gas into the annular airbag assembly;

[0009] The gas discharge structure discharges the gas inside the annular airbag assembly.

[0010] According to the present invention, the annular airbag assembly further includes a first annular airbag disposed between the areola coverage area and the peripheral breast contact area, closer to the areola coverage area, and a second annular airbag disposed between the areola coverage area and the peripheral breast contact area, parallel to the first annular airbag; a one-way ventilation valve is provided between the first annular airbag and the second annular airbag to realize the gas flow between the two.

[0011] According to the present invention, the one-way vent valve further allows gas to flow from the second annular airbag to the first annular airbag, and the spring valve core of the one-way vent valve has resistance; the one-way vent valve opens when the positive pressure of the second annular airbag makes the pressure difference between the two sides greater than the valve core resistance, or the negative pressure of the first annular airbag makes the pressure difference between the two sides greater than the valve core resistance.

[0012] According to the present invention, a conversion interface is further provided at the end of the areola coverage area of ​​the dual-airbag breast shield body, and a milk collection bottle is threadedly connected below the conversion interface.

[0013] According to the present invention, the conversion interface further includes a vacuum port connected to an external vacuum structure, which draws the nipple and areola region through intermittent negative pressure of vacuum gas.

[0014] According to the present invention, the intensity range of the negative pressure is -10 to -20 kPa.

[0015] According to the present invention, it further includes a pressure sensor for monitoring the pressure of the second annular airbag; and a pressure data analyzer electrically connected to the pressure sensor for analyzing the pressure inside the second annular airbag, generating a pressure feedback signal, and thereby controlling the start and stop of the gas injection structure and the gas discharge structure.

[0016] A timer that records the operating time of the vacuum structure, gas injection structure, and gas exhaust structure;

[0017] The control device receives pressure feedback signals from the pressure data analyzer, records time using a timer, and controls the inflation and deflation cycle of the annular airbag assembly.

[0018] According to the present invention, the body of the double-airbag breast shield is made of silicone.

[0019] As a second aspect of the present invention, a control method for a lactation massage device combining dual-airbag compression and negative pressure suction is provided, comprising:

[0020] Set the maximum inflation pressure value P_press of the second annular airbag and the spring valve core resistance P_resistance of the one-way vent valve to start the airbag inflation function, and the gas injection structure will start inflating the second annular airbag.

[0021] The pressure data analyzer monitors the real-time pressure inside the second annular airbag;

[0022] The gas injection and gas discharge structures are controlled to start and stop based on the pressure feedback signal from the pressure data analyzer; when the pressure in the second annular airbag is greater than P, the one-way vent valve opens to inflate the first annular airbag; when the pressure in the second annular airbag reaches the set value P after pressing, the pressure feedback signal starts the timer and counts down.

[0023] After the timer starts, inflation maintains the pressure of the second annular airbag near the P press.

[0024] After the timer countdown ends, the inflation stops and the gas inside the annular airbag assembly is released.

[0025] When the pressure inside the second annular airbag drops to 0 kPa, the pressure feedback signal stops the exhaust through the control device and starts the inflation.

[0026] The first and second annular airbags are inflated and deflated in a cyclical manner according to the above steps until the lactation device is paused or shut down.

[0027] Furthermore, the control device also includes a negative pressure suction module to adjust the negative pressure magnitude and negative pressure mode.

[0028] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0029] This invention enables sequential inflation and pressurization from the second annular airbag to the first annular airbag, forming a stable pressure reduction gradient. Furthermore, through the air extraction structure, air is depressurized layer by layer from the first annular airbag to the second annular airbag, following the anatomical structure and physiological lactation mechanism of the mammary gland. This massages and presses the breast from the periphery to the center, promoting the secretion of milk from the peripheral milk ducts to the central milk ducts.

[0030] For patients with milk stasis in the peripheral breast region, this invention can enhance the pressure exerted by the peripheral airbag on the peripheral breast region by increasing the pressure within the second annular airbag and the resistance of the one-way ventilation valve. If the milk stasis is closer to the central breast region, the pressure exerted by the first annular airbag on the central breast region can be enhanced by decreasing the resistance of the one-way ventilation valve. Furthermore, the airbag pressure and negative pressure intensity of this invention are adjustable to meet the needs of different users.

[0031] This invention utilizes a dual-chamber airbag connected by a one-way ventilation valve to achieve effective, sequential, and gradient pressure on the mammary gland from the periphery to the center. Simultaneously, negative pressure suction in the areola area accelerates milk drainage, significantly improving milk stasis and poor lactation. It is suitable for breastfeeding women, especially those with mastitis who require emptying their breasts. Attached Figure Description

[0034] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] This invention provides a breast massage device combining dual-airbag compression and negative pressure suction, comprising a dual-airbag breast shield body 1. The dual-airbag breast shield 1 is funnel-shaped, including an annular areola coverage area 2 and a breast periphery contact area 5. Two independent first annular airbags 3 and second annular airbags 4 are arranged side-by-side between the two areas. The diameter of the first annular airbag 3, closer to the areola coverage area 2, is smaller than the diameter of the second annular airbag 4, farther from the areola coverage area 2. A one-way ventilation valve 34 is provided between the two annular airbags. Gas flows from the second annular airbag 4 to the first annular airbag 3 through the one-way ventilation valve 34, and the spring valve core of the one-way ventilation valve 34 has a certain resistance. The one-way ventilation valve 34 opens when the pressure difference between the two sides caused by the positive pressure of the second annular airbag 4 or the negative pressure of the first annular airbag 3 exceeds the valve core resistance; otherwise, it closes. Three, four, or more annular airbags can be arranged between the areola coverage area 2 and the outer periphery of the breast contact area 5, with the diameter of the multiple annular airbags increasing progressively from the areola coverage area 2 to the outer periphery of the breast contact area 5. The remaining parts of each airbag are individually sealed, connected externally by fabric. The dual-airbag breast shield body 1 is preferably made of silicone, with anti-friction protrusions on its inner surface to increase the friction between the dual-airbag breast shield body 1 and the skin, reducing displacement of the dual-airbag breast shield body 1 during use and ensuring effective use.

[0036] A conversion interface 6 is provided at the end of the areola coverage area 2 of the dual-airbag breast pump body 1. The conversion interface 6 has an internal thread below it, and the upper port of the milk collection bottle 7 has an external thread that matches the internal thread. The milk collection bottle 7 is threadedly connected to the conversion interface 6 to achieve milk collection.

[0037] The inner wall of the conversion interface 6 is adapted to the outer wall of the areola coverage area 2 of the double-airbag breast suction shield body 1. The upper side is connected to the vacuum pump 10 via vacuum inlet 6a and vacuum tube 6b. The vacuum pump intermittently applies negative pressure to the nipple and areola area. The negative pressure suction intensity of the vacuum pump 10 can be adjusted using the increase and decrease buttons on the control device 13. The adjustable negative pressure intensity of the vacuum pump 10 is -10 to -20 kPa. After activating the negative pressure suction function of the breast pump, the negative pressure is maintained for 2 seconds, then paused for 2 seconds, with each cycle lasting 4 seconds, until the breast pump is paused or turned off.

[0038] The second annular airbag 4 has an air inlet 4a. An external air supply structure injects gas into the second annular airbag 4 through the air inlet 4a, causing it to inflate and apply pressure to the area around the breast, thus squeezing and draining the accumulated milk. The maximum inflation pressure P inside the second annular airbag 4 can be adjusted using the increase and decrease buttons on the controller, with an adjustment range of 10 to 20 kPa. Preferably, the external air supply structure is an air pump 8, which inflates the second annular airbag 4 through the air inlet 4a via the air inlet 4b.

[0039] The first annular airbag 3 has an air extraction port 3a, through which an external air extraction structure extracts gas for easy gas discharge. Preferably, the external air extraction structure is an air pump 9, which draws gas from the first annular airbag 3 through the air extraction pipe 3b and air extraction port 3a.

[0040] In this embodiment, the resistance of the spring valve core of the one-way vent valve 34 can be manually adjusted via an external resistance adjustment knob 341, with an adjustment range of 0-10 kPa. Therefore, the pressure range achievable by the first annular airbag 3 is 0-20 kPa. The outer circumference of the resistance adjustment knob 341 is rotatable and is marked with a scale of 0-10, corresponding to specific resistance values. The value pointed to by the tip of the triangular indicator mark located in the central fixed part of the resistance adjustment knob 341 is the spring valve core resistance at this time.

[0041] In this embodiment, the outer surface of the areola coverage area 2 of the dual-airbag breast shield body 1 is adhered to the first annular airbag 3 via Velcro, and the outer surface of the breast peripheral contact area 5 is adhered to the second annular airbag 4 via Velcro. This adhesive structure facilitates the replacement of the annular airbags.

[0042] In this embodiment of the application, in order to further and better control the pressure of the annular airbag, a pressure sensor 4c is provided inside the second annular airbag 4. It is electrically connected to the pressure data analyzer 11, which communicates with the timer 12 and is connected to the inflation pump 8 and the deflation pump 9 through the control device 13.

[0043] The working process of this invention is as follows: the lactation device is turned on according to the switch signal, the maximum inflation pressure intensity value P of the second annular airbag 4 and the spring valve core resistance P of the one-way air valve 34 are set, the airbag pressing function of the lactation therapy device is started, the air pump 8 inflates and pressurizes the second annular airbag 4 and the first annular airbag 3 in sequence and at intervals, and adjusts the pressure of the two annular airbags according to the control logic.

[0044] The control logic is as follows:

[0045] Pressure data analyzer 11 monitors the real-time pressure of the second annular airbag 4;

[0046] The pressure feedback signal from the pressure data analyzer 11 controls the start and stop of the inflation pump 8 and the deflation pump 9; after the airbag pressing function is activated, the inflation pump 8 inflates the second annular airbag 4.

[0047] When the pressure inside the second annular airbag 4 is greater than the resistance P, the one-way ventilation valve 34 opens and inflates the first annular airbag 3.

[0048] When the pressure inside the second annular airbag 4 reaches the set value P and is pressed, the pressure feedback signal starts the timer 12 and counts down for 4 seconds;

[0049] After the timer 12 starts, the air pump 8 continues to inflate, keeping the pressure of the second annular airbag 4 near the P press. After the countdown ends, the control device 13 stops the air pump 8 and starts the air pump 9 to sequentially expel the gas from the first annular airbag 3 and the second annular airbag 4.

[0050] When the pressure inside the second annular airbag 4 drops to 0 kPa, the pressure feedback signal stops the air pump 9 and starts the inflation pump 8 through the control device 13.

[0051] The first annular airbag 3 and the second annular airbag 4 are cyclically inflated and deflated according to the above control logic until the lactation device is paused or shut down.

[0052] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
