Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to a hands-free integrated electric nipple corrector. Background Art

[0002] The nipple cannot protrude but is sunken inward, which is called inverted nipple. The degree of inverted nipple varies from person to person. In mild cases, the nipple is only flat or retracted to varying degrees. It can protrude or be squeezed out after stimulation. In severe cases, the nipple is completely sunken into the areola and cannot be pulled out. It is crater-like and often accompanied by secretions or odor. Even if the inverted nipple is squeezed out, it is generally smaller, often without an obvious nipple neck, and is split.

[0003] In the prior art, when treating inverted nipples, a negative pressure suction device is used to pull the inverted nipples, thereby lengthening the mammary ducts and fiber cords. However, the existing nipple corrector has low correction accuracy during correction, resulting in low correction efficiency for inverted nipples. Summary of the invention

[0004] To this end, the present invention provides a hands-free integrated electric nipple corrector to overcome the problem of low efficiency in correcting inverted nipples in the prior art due to the inability to accurately control the adsorption process of the nipple.

[0005] To achieve the above object, the present invention provides a hands-free integrated electric nipple corrector, comprising:

[0006] A control unit, for controlling the correction process of the nipple, the control unit comprising an air pump, the air pump being used to input and output gas to the adsorption unit, the control unit further comprising a controller, the controller being used to control the adsorption process of the adsorption unit on the nipple;

[0007] A transmission unit, used for gas transmission to change the gas pressure during nipple correction, one end of which is connected to the control unit, and an air suction hose and an air delivery hose are arranged inside the transmission unit so that the control unit controls the input and output of gas to the adsorption unit;

[0008] The adsorption unit is used to correct the inverted nipple, and is connected to the transmission unit. The adsorption unit includes four airbags, and the airbags are used to correct the direction of the nipple. The inner wall of each airbag is provided with a pressure sensor to detect the pressure between the nipple and the airbag;

[0009] The controller is also used to obtain an inverted nipple image, and divide the inverted image into regions according to grayscale values ​​to determine preselected regions, and determine the areola region in the inverted image according to the average grayscale value A of each preselected region. The controller is also used to determine the inverted state of the nipple according to the graphic texture complexity C of the areola region. The controller is also used to control the suction volume of the air pump according to the inverted state of the nipple to control the suction force of the suction unit on the nipple. The controller is also used to adjust the suction volume of the air pump according to the proportion of the nipple in the inverted image. The controller is also used to correct the adjusted suction volume according to the average pressure F between the airbag and the nipple.

[0010] Furthermore, when the controller is determining the areola area, the controller collects and obtains an inverted image of the nipple, and divides the inverted image into regions according to the grayscale value, and uses the circular region formed after the division as the preselected region. The controller compares the average grayscale value A of each preselected region with the preset grayscale value A0, and determines the areola area according to the comparison result, wherein:

[0011] When A≤A0, the controller determines that the preselected area is a preselected areola area;

[0012] When A>A0, the controller determines that the preselected area is a non-areola area.

[0013] Furthermore, after the controller completes the determination of the preselected areola regions, the controller determines the areola regions according to the number of preselected areola regions, wherein:

[0014] When the number of pre-selected areola regions is single, the controller uses the pre-selected areola region as the areola region;

[0015] When there are multiple pre-selected areola regions, the controller selects the pre-selected areola region with the largest area among the pre-selected areola regions as the areola region.

[0016] Furthermore, when determining the inverted state of the nipple, the controller takes the circular area in the center of the areola area as the nipple area, obtains the graphic texture complexity C of the areola area, and compares it with each preset texture complexity, and determines the inverted state of the nipple according to the comparison result, wherein,

[0017] When C≤C1, the controller determines that the nipple is not inverted and no correction is required;

[0018] When C1<C≤C2, the controller determines that the nipple is partially inverted;

[0019] When C2<C, the controller determines that the nipple is completely inverted;

[0020] Wherein, C1 is a first preset texture complexity, C2 is a second preset texture complexity, and C1<C2.

[0021] Furthermore, when the controller controls the air volume of the air pump, the controller controls the adsorption force of the adsorption unit according to the inverted state of the nipple, and the controller controls the adsorption force of the adsorption unit on the nipple by changing the air volume of the air pump, wherein:

[0022] When the nipple is partially inverted, the controller controls the air pump to pump air at a suction volume of D1;

[0023] When the nipple is completely inverted, the controller controls the air pump to pump air at a suction volume of D2;

[0024] Wherein, D1 is the first preset air extraction volume, D2 is the second preset air extraction volume, and D1<D2.

[0025] Furthermore, when the controller adjusts the air volume of the air pump, the controller compares the nipple proportion M with each preset proportion, and adjusts the air volume Di of the air pump according to the comparison result, setting i=1,2, wherein,

[0026] When M>M2, the controller determines that the nipple ratio meets the requirement and does not make any adjustment;

[0027] When M1<M≤M2, the controller adjusts the air pump's suction volume to Da1, setting Da1=Di×m, where m is a preset adjustment coefficient, 1<m<1.1;

[0028] When M≤M1, the controller adjusts the air pump's suction volume to Da2, setting Da2=Da1+Da1×(M1-M) / M1;

[0029] Among them, M1 is the first preset nipple ratio, M2 is the second preset nipple ratio, and M1<M2.

[0030] Furthermore, while controlling the adsorption unit to perform adsorption, the controller also controls each of the second gas valves to open and deliver a preset volume of gas Va1 to the airbag. After the gas is delivered, the controller obtains the average pressure F between the airbag and the nipple, and compares the average pressure F with each preset pressure, and corrects the adjusted suction volume Dai according to the comparison result, setting i=1,2, where,

[0031] When F<F1, the controller determines that the nipple is small and increases the gas volume in the airbag to proceed to the next step of determination;

[0032] When F1≤F<F2, the controller determines that the nipple has been sucked out and no correction is required;

[0033] When F2≤F, the controller determines that the adsorption force of the adsorption unit is large, and corrects the suction volume to Db, setting Db=Dai-Dai×(F-F2) / F;

[0034] Wherein, F1 is the first preset pressure, F2 is the second preset pressure, and F1<F2.

[0035] Further, when the controller increases the gas volume in the airbag, the controller adjusts the gas volume in the airbag to Va2, sets Va2=Va1×n, n is the preset volume adjustment coefficient, 1<n<1.2, and after increasing the gas volume in the airbag, the controller obtains the average pressure G between the airbag and the nipple at this time, and compares the average pressure G with each preset pressure, and corrects the adjusted suction volume Dai according to the comparison result, wherein,

[0036] When G<F1, the controller determines that the nipple is not completely sucked out, and corrects the suction volume to Dc1, setting Dc1=Dai+Dai×(F1-G) / F1;

[0038] When F2≤G, the controller determines that the adsorption force of the adsorption unit is large, and corrects the suction volume to Dc2, setting Dc2=Dai-Dai×(G-F2) / G.

[0039] Furthermore, the transmission unit also includes a first connecting pipe, one end of which is connected to the control unit, the other end of the first connecting pipe is connected to the second connecting pipe, a first threaded sleeve is provided at the connection between the first connecting pipe and the second connecting pipe to increase the connection strength, the other end of the second connecting pipe is connected to a three-way hose, the other two interfaces of the three-way hose are symmetrically connected to a third connecting pipe, the other end of the third connecting pipe is connected to a fourth connecting pipe through a second threaded sleeve, a first air valve is provided inside the end of the fourth connecting pipe close to the third connecting pipe, the fourth connecting pipe is rotatably connected to the adsorption unit through a connecting port, and the control unit can control the two adsorption units to work separately or simultaneously by controlling the opening and closing of the two first air valves.

[0040] Further, the control unit also includes a main body, and portable rings are provided on both sides of the main body, and the portable rings are used to connect with external ropes for easy carrying. An inspection panel is provided on the upper surface of the main body for easy inspection. A plurality of fixing bolts are provided on the upper surface of the inspection panel. A connecting hole is opened on one side surface of the main body, and the connecting hole is used to connect with the transmission unit. A fixing ring is provided on the outer side of the connecting hole to improve the stability of the connection of the connecting hole.

[0041] The adsorption unit also includes a shell, and a rubber pad is provided at the adsorption end of the shell, and the rubber pad is used to increase the sealing between the shell and the human body. An air supply channel is provided on the inner side of the rubber pad, and the air supply channel is in a closed state. An air suction channel is provided on the inner side of the air supply channel. A second air valve is provided on the side of the airbag close to the air supply channel, and the second air valve is used to control the gas input and output of the airbag.

[0042] Compared with the prior art, the beneficial effects of the present invention lie in that the input and output of the gas in the adsorption unit are controlled by a control unit, the gas is transmitted through the transmission unit, and a three-way hose is provided in the output unit so that the gas can be transmitted to the two adsorption units, so that the two nipples can be corrected at the same time to improve the correction efficiency, and by providing a first air valve in the transmission unit, the two adsorption units can be effectively controlled to work separately or simultaneously to further improve the correction efficiency, and by providing an air suction hose and an air delivery hose in the transmission unit, the adsorption unit can be effectively controlled to perform adsorption to correct the nipple, and the adsorption unit is provided with an air suction channel for air suction to adsorb the nipple and suck out the inverted nipple, and the degree of nipple suction is determined by providing an air bag, thereby accurately controlling the adsorption strength to increase the correction efficiency of the nipple.

[0043] In particular, when the controller controls the adsorption unit to perform correction, the controller first obtains an inverted nipple image, and accurately analyzes the inverted image to determine the areola area in the image. The degree of nipple inversion is determined by determining the areola area, thereby improving the accuracy of nipple correction. When determining the areola area, the controller divides the inverted image into several areas, and obtains the average grayscale value A of the circular area. The skin color of the areola is darker than the skin color of other places. Therefore, when the average grayscale value A is within a preset value, the color of the circular area has met the skin color of the areola. The circular area is used as a preselected areola area for further accurate determination. After judging each circular area, the controller obtains the number of preselected areola areas. If there is only one, then the preselected areola area is the areola area. If the number is greater than 1, the area with the largest area in the preselected areola areas is used as the areola area, thereby completing the determination of the areola area in the inverted image. The controller can further improve the correction efficiency of the nipple by accurately screening and determining the areola area.

[0044] In particular, after determining the areola area in the inverted image, the controller determines the inverted degree according to the graphic texture complexity C of the areola area. Since the areola near the inverted position will form a wavy shape after the nipple is inverted, the more serious the nipple inversion is, the greater the texture complexity of the areola area in the inverted image. The controller compares the graphic texture complexity C of the areola area with a preset value. When the graphic texture complexity C is within the preset value, it proves that no inversion has occurred. If it is within the preset range, it proves that the nipple is partially inverted. If it is greater than the preset value, it proves that it is completely inverted. The controller determines the degree of nipple inversion by using the graphic texture complexity C, which effectively improves the accuracy of the determination, thereby further improving the efficiency of nipple correction. After the determination of the nipple inversion state is completed, the controller controls the air pump suction volume according to the inverted state to accurately control the adsorption force of the adsorption unit on the nipple, thereby improving the efficiency of nipple correction. When controlling the suction volume, the controller selects different preset suction volumes for suction according to different inverted states to improve the accuracy of controlling the nipple adsorption force, thereby further improving the efficiency of nipple correction.

[0045] In particular, after determining the air pump suction volume, the controller also adjusts the air suction volume according to the nipple proportion in the inverted image to improve the accuracy of controlling the nipple adsorption force. The controller compares the nipple proportion M with a preset value. If it is greater than the preset value, it proves that the nipple is not deeply inverted and there is no need to adjust the air suction volume. If the nipple proportion M is within the preset range, it proves that the nipple is deeply inverted and the air suction volume needs to be increased to improve the adsorption efficiency of the nipple. If the nipple proportion M is within the preset value, it proves that the nipple is more deeply inverted. At this time, the controller calculates the adjusted air suction volume according to the difference between the nipple proportion M and the preset value, so that the calculated air suction volume meets the adsorption requirement of the nipple, thereby further improving the correction efficiency of the nipple.

[0046] In particular, the controller also corrects the amount of air pumped according to the average pressure between the airbag and the nipple during adsorption to further control the accuracy of nipple adsorption. The controller opens the second air valve to inflate each airbag, and effectively controls the squeezing state between each airbag and the nipple by controlling the volume of gas in the airbag. After the airbag is filled with gas, the controller compares the average pressure F between the airbag and the nipple with a preset value to correct the amount of air pumped. When the average pressure F is less than the preset value, it is determined that the nipple is small and the accurate pressure value cannot be obtained, and the gas volume in each airbag needs to be increased to correct the amount of air pumped. Correction: if F is within the preset value range, no correction is required, and the air extraction volume has met the demand; if F is above the preset value, the corrected air extraction volume needs to be calculated based on the difference to make the air extraction volume optimal, so as to improve the correction efficiency of the nipple. After increasing the gas volume in each airbag, the controller obtains the average pressure G of the airbag and the nipple at this time. If G is less than the preset value, it proves that the adsorption force is weak and the air extraction volume needs to be increased. If it is within the preset range, it is a normal state. If it is above the preset value, the air extraction volume needs to be corrected based on the difference with the preset value to further improve the accuracy of the air extraction volume, thereby improving the correction efficiency of the nipple.

[0057] Specifically, in this embodiment, the input and output of the gas in the adsorption unit are controlled by a control unit, and the gas is transmitted through the transmission unit. The output unit is provided with a three-way hose so that the gas can be transmitted to the two adsorption units, and the two nipples can be corrected at the same time to improve the correction efficiency. In the transmission unit, by providing a first gas valve, the two adsorption units can be effectively controlled to work separately or simultaneously to further improve the correction efficiency. In the transmission unit, by providing an air suction hose and an air delivery hose, the adsorption unit can be effectively controlled to adsorb to correct the nipples. It can be understood that this embodiment does not specifically limit the number of the adsorption units, and those skilled in the art can set them according to actual needs. The three-way hose can be replaced with a connecting pipe so that only one adsorption unit is set to work, and it only needs to meet the correction requirements for the nipples. In the transmission unit of this embodiment, the air suction hose and the air delivery hose should be connected in a sleeve, and the air delivery hose is sleeved on the outside of the air suction hose to facilitate the adsorption of the adsorption unit. The two hoses can also be arranged in parallel, and it only needs to meet the input and output requirements of the gas in the adsorption unit.

[0058] See also Figure 2 As shown, the control unit 1 of this embodiment includes a main body 101, and portable rings 102 are provided on both sides of the main body 101. The portable rings 102 are used to connect with external ropes for easy carrying. An inspection panel 103 is provided on the upper surface of the main body 101 for easy inspection.

[0059] See also Figure 3As shown, the adsorption unit 10 includes a shell 1000, and a rubber cushion 1001 is provided at the adsorption end of the shell, and the rubber cushion 1001 is used to increase the sealing between the shell and the human body. An air delivery channel 1002 is provided on the inner side of the rubber cushion 1001, and the air delivery channel 1002 is in a closed state. An air suction channel 1003 is provided on the inner side of the air delivery channel 1002, and four air bags 1004 are symmetrically provided on the inner wall of the air suction channel 1003, and each of the air bags 1004 is used to correct the direction of the nipple. A second air valve 1005 is provided on the side of each air bag 1004 close to the air delivery channel 1002, and the second air valve 1005 is used to control the gas input and output of the air bag 1004, and a pressure sensor is provided on the inner wall of each air bag 1004 to detect the pressure between the nipple and the air bag.

[0060] Specifically, the suction unit of the present embodiment is provided with a suction channel for suction to suction the nipple, so as to suck out the inverted nipple, and the degree of suction of the nipple is determined by providing an airbag, so as to accurately control the suction force to increase the correction efficiency of the nipple. It is understandable that the present embodiment does not specifically limit the number of the airbags, and those skilled in the art can also adjust the number of airbags to three or five, etc. It is worth noting that if only two airbags are provided for pressure detection, the detection result will be affected by the direction of sucking out the nipple, resulting in inaccurate detection results and affecting the precise control of the suction force. Therefore, when setting the number of the airbags, it should be ensured that there are more than 3 airbags. The best real-time method is to set 4 airbags for all-round pressure detection to improve the accuracy of the control of the suction force, thereby improving the correction efficiency of the nipple.

[0061] Specifically, when the controller controls the adsorption unit to perform correction, the controller collects and obtains the inverted image of the nipple, divides the inverted image into regions according to the grayscale value, and uses the circular region formed after the division as the preselected region. The controller compares the average grayscale value A of each preselected region with the preset grayscale value A0, and determines the areola region according to the comparison result, wherein:

[0062] When A≤A0, the controller determines that the preselected area is a preselected areola area;

[0063] When A>A0, the controller determines that the preselected area is a non-areola area.

[0064] Specifically, after the controller completes the determination of the preselected areola regions, the controller determines the areola regions according to the number of preselected areola regions, wherein:

[0065] When the number of pre-selected areola regions is single, the controller uses the pre-selected areola region as the areola region;

[0066] When there are multiple pre-selected areola regions, the controller selects the pre-selected areola region with the largest area among the pre-selected areola regions as the areola region.

[0067] Specifically, when the controller in this embodiment controls the adsorption unit to perform correction, it first obtains an inverted nipple image, and accurately analyzes the inverted image to determine the areola area in the image. The degree of nipple inversion is determined by determining the areola area, thereby improving the accuracy of nipple correction. When determining the areola area, the controller divides the inverted image into several areas, and obtains the average grayscale value A of the circular area. The skin color of the areola is darker than the skin color of other places. Therefore, when the average grayscale value A is within a preset value, the color of the circular area has met the skin color of the areola. The circular area is used as a preselected areola area for further accurate determination. After judging each circular area, the controller obtains the number of preselected areola areas. If there is only one, then the preselected areola area is the areola area. If the number is greater than 1, the area with the largest area in the preselected areola area is used as the areola area, thereby completing the determination of the areola area in the inverted image. The controller can further improve the correction efficiency of the nipple by accurately screening and determining the areola area.

[0068] Specifically, after determining the areola area, the controller takes the circular area in the center of the areola area as the nipple area, obtains the graphic texture complexity C of the areola area, and compares it with each preset texture complexity, and determines the inverted state of the nipple according to the comparison result, wherein,

[0069] When C≤C1, the controller determines that the nipple is not inverted and no correction is required;

[0070] When C1<C≤C2, the controller determines that the nipple is partially inverted;

[0071] When C2<C, the controller determines that the nipple is completely inverted;

[0072] Wherein, C1 is a first preset texture complexity, C2 is a second preset texture complexity, and C1<C2.

[0073] Specifically, after the controller determines the inverted state of the nipple, the controller controls the adsorption force of the adsorption unit according to the inverted state of the nipple. The controller controls the adsorption force of the adsorption unit on the nipple by changing the air volume of the air pump, wherein:

[0074] When the nipple is partially inverted, the controller controls the air pump to pump air at a suction volume of D1;

[0075] When the nipple is completely inverted, the controller controls the air pump to pump air at a suction volume of D2;

[0076] Wherein, D1 is the first preset air extraction volume, D2 is the second preset air extraction volume, and D1<D2.

[0077] Specifically, after determining the areola area in the inverted image, the controller in this embodiment determines the degree of inversion according to the graphic texture complexity C of the areola area. Since the areola near the inverted position will form a wavy shape after the nipple is inverted, the more severe the nipple inversion is, the greater the texture complexity of the areola area in the inverted image. The controller compares the graphic texture complexity C of the areola area with a preset value. When the graphic texture complexity C is within the preset value, it proves that no inversion has occurred. If it is within the preset range, it proves that the nipple is partially inverted. If it is greater than the preset value, it proves that it is completely inverted. Inverted nipple, the controller determines the degree of nipple inversion by graphic texture complexity C, which effectively improves the accuracy of the determination, thereby further improving the efficiency of nipple correction. After the inverted nipple state is determined, the controller controls the air pump volume according to the inverted state to accurately control the adsorption force of the adsorption unit on the nipple, thereby improving the efficiency of nipple correction. When controlling the air pump volume, the controller selects different preset air pump volumes for air pumping according to different inverted states to improve the accuracy of controlling the adsorption force of the nipple, thereby further improving the efficiency of nipple correction.

[0078] Specifically, when controlling the adsorption unit to adsorb, the controller also adjusts the air pump suction volume according to the nipple ratio, wherein the nipple ratio is the ratio of the nipple area to the areola area in the inverted image. The controller compares the nipple ratio M with each preset ratio, and adjusts the air pump suction volume Di according to the comparison result, setting i=1,2, wherein,

[0079] When M>M2, the controller determines that the nipple ratio meets the requirement and does not make any adjustment;

[0080] When M1<M≤M2, the controller adjusts the air pump's suction volume to Da1, setting Da1=Di×m, where m is a preset adjustment coefficient, 1<m<1.1;

[0081] When M≤M1, the controller adjusts the air pump's suction volume to Da2, setting Da2=Da1+Da1×(M1-M) / M1;

[0082] Among them, M1 is the first preset nipple ratio, M2 is the second preset nipple ratio, and M1<M2.

[0083] Specifically, after determining the air pump suction volume, the controller also adjusts the air suction volume according to the nipple proportion in the inverted image to improve the accuracy of controlling the nipple adsorption force. The controller compares the nipple proportion M with a preset value. If it is greater than the preset value, it proves that the nipple is not deeply inverted and there is no need to adjust the air suction volume. If the nipple proportion M is within the preset range, it proves that the nipple is deeply inverted and the air suction volume needs to be increased to improve the adsorption efficiency of the nipple. If the nipple proportion M is within the preset value, it proves that the nipple is more deeply inverted. At this time, the controller calculates the adjusted air suction volume according to the difference between the nipple proportion M and the preset value, so that the calculated air suction volume meets the adsorption requirement of the nipple, thereby further improving the correction efficiency of the nipple.

[0084] Specifically, while controlling the adsorption unit to perform adsorption, the controller also controls each of the second gas valves to open and deliver a preset volume of gas Va1 to the airbag. After the gas is delivered, the controller obtains the average pressure F between the airbag and the nipple, and compares the average pressure F with each preset pressure, and corrects the adjusted suction volume Dai according to the comparison result, setting i=1,2, where,

[0085] When F<F1, the controller determines that the nipple is small and increases the gas volume in the airbag to proceed to the next step of determination;

[0086] When F1≤F<F2, the controller determines that the nipple has been sucked out and no correction is required;

[0087] When F2≤F, the controller determines that the adsorption force of the adsorption unit is large, and corrects the suction volume to Db, setting Db=Dai-Dai×(F-F2) / F;

[0088] Wherein, F1 is the first preset pressure, F2 is the second preset pressure, and F1<F2.

[0089] Specifically, when the controller increases the gas volume in the airbag, the controller adjusts the gas volume in the airbag to Va2, sets Va2=Va1×n, n is the preset volume adjustment coefficient, 1<n<1.2, and after increasing the gas volume in the airbag, the controller obtains the average pressure G between the airbag and the nipple at this time, and compares the average pressure G with each preset pressure, and corrects the adjusted suction volume Dai according to the comparison result, wherein,

[0090] When G<F1, the controller determines that the nipple is not completely sucked out, and corrects the suction volume to Dc1, setting Dc1=Dai+Dai×(F1-G) / F1;

[0091] When F1≤G<F2, the controller determines that the nipple has been sucked out and no correction is required;

[0092] When F2≤G, the controller determines that the adsorption force of the adsorption unit is large, and corrects the suction volume to Dc2, setting Dc2=Dai-Dai×(G-F2) / G.

[0093] Specifically, the controller in this embodiment also corrects the amount of air pumped according to the average pressure between the airbag and the nipple during adsorption to further control the accuracy of nipple adsorption. The controller opens the second air valve to inflate each airbag, and can effectively control the squeezing state between each airbag and the nipple by controlling the volume of gas in the airbag. After the airbag is filled with gas, the controller compares the average pressure F between the airbag and the nipple with a preset value to correct the amount of air pumped. When the average pressure F is less than the preset value, it is determined that the nipple is small and the accurate pressure value cannot be obtained, and the gas volume in each airbag needs to be increased. , for correction. If F is within the preset value range, no correction is required, and the air extraction volume has met the demand. If F is above the preset value, the corrected air extraction volume needs to be calculated based on the difference to make the air extraction volume optimal, so as to improve the correction efficiency of the nipple. After increasing the gas volume in each airbag, the controller obtains the average pressure G of the airbag and the nipple at this time. If G is less than the preset value, it proves that the adsorption force is small and the air extraction volume needs to be increased. If it is within the preset range, it is a normal state. If it is above the preset value, the air extraction volume needs to be corrected according to the difference with the preset value to further improve the accuracy of the air extraction volume, thereby improving the correction efficiency of the nipple.
