Description

Technical Field

[0001] The present invention relates to the technical field of medical imaging devices, and in particular to a wearable ultrasonic patch and a data processing method. Background Art

[0002] Wearable ultrasound patches are widely used in the field of heart disease monitoring. Wearable ultrasound patches use ultrasonic transducers to monitor blood pressure changes of heart disease and critically ill patients in real time and continuously. According to the monitored physiological data, treatment plans are adjusted in time to improve treatment effects. In addition, ultrasound patches can also be used for cervical curvature monitoring, hemodynamic monitoring, bladder monitoring, vascular access monitoring, etc.

[0003] While the ultrasound patch is placed on the subject's body surface, its position may move. If the ultrasound patch moves during monitoring, the corresponding body structure may move, the acquired signal data may change, and the final monitoring result may not be accurate. To this end, a fixing unit can be used to fix the ultrasound patch on the subject's body surface to prevent the ultrasound patch from moving.

[0004] In order to improve the monitoring accuracy, it is necessary to ensure good coupling between the ultrasonic transducer and the patient's body. Generally, ultrasonic conductive gel is coated on the surface of the patient's body, and pressure is applied to the ultrasonic transducer to make it contact with the surface of the gel layer.

[0057] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0058] like Figure 1 As shown, the present invention provides a wearable ultrasound patch, including a patch body 1, and the patch body 1 is generally composed of a PDMS substrate layer, a flexible electrode layer, a circuit device layer, and an upper flexible substrate layer.

[0059] like Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, auxiliary positioning seats 2 are provided at both ends of the patch body 1, and a positioning sticker 3 is provided on the side of the auxiliary positioning seat 2 away from the patch body 1, and the positioning sticker 3 is adhered to the surface of the wearing area.

[0060] The positioning patch 3 is fixedly connected with a positioning component 4, and the auxiliary positioning seat 2 is connected to the positioning component 4. The positioning component 4 can pull and adjust the position of the auxiliary positioning seat 2 to drive the patch body 1 to be in a straight state when the auxiliary positioning seat 2 is pulled to both sides.

[0061] The positioning stickers 3 on both sides are usually pasted in symmetrical positions. After the two positioning stickers 3 are pasted, the position of the auxiliary positioning seat 2 is adjusted by the adjustment component 4. Generally, the auxiliary positioning seat 2 is pulled toward both sides to increase the distance between the auxiliary positioning seat 2, and gradually drive the patch body 1 to be in a straight and horizontal state.

[0062] Among them, Figure 3 and Figure 4 As shown, a sleeve 5 is arranged between the two auxiliary positioning seats 2 and on the periphery of the patch body 1, both ends of the sleeve 5 are connected to the auxiliary positioning seats 2, and a smooth connecting plane 6 is formed on the bottom surfaces of the sleeve 5 and the auxiliary positioning seats 2, and a first adhesive layer 7 that fits the surface of the wearing area is laid on the connecting plane 6.

[0063] The first adhesive layer 7 is mainly used to position the sleeve 5 and the auxiliary positioning seat 2 on the surface of the wearing area to achieve the fixation of the wearable ultrasonic patch.

[0064] An inner cavity 8 is formed between the edge of the sleeve 5 and the auxiliary positioning seat 2 and at the bottom of the patch body 1. The patch body 1 and the auxiliary positioning seat 2 are provided with a hole structure 9 connected to the inner cavity 8, and the auxiliary positioning seat 2 is clamped with a blocking structure 10 that blocks the hole structure 9.

[0065] A gel layer is formed at the bottom of the patch body 1, and the solvent is injected into the inner cavity 8 from the porous structure 9 to mix with the gel layer at the bottom of the patch body 1 and form a second adhesive layer that adheres to the surface of the wearing area. The blocking structure 10 can prevent the mixture in a liquid state from overflowing.

[0066] When the patch body 1 tends to be stretched and horizontal, the depth of the inner cavity 8 formed at the bottom thereof is generally evenly distributed everywhere, so as to avoid uneven distribution of gel due to different depths at different positions of the inner cavity 8 .

[0067] In the present invention, the patch body 1 is fixed on the surface of the wearing area by using the auxiliary positioning seat 2. In addition, the first adhesive layer 7 laid on the bottom of the sleeve 5 and the auxiliary positioning seat 2 is used to ensure the fixing effect of the wearable ultrasonic patch on the surface of the wearing area, avoid the wearable ultrasonic patch from moving, and further ensure the accuracy of the monitoring data;

[0068] In addition, the inner cavity 8 is formed by using the sleeve 5 and the auxiliary positioning seat 2, and a hole structure 9 is set on the auxiliary positioning seat 2. Before monitoring, the solvent is injected into the inner cavity 8 through the hole structure 9. The solvent is mixed with the gel layer to form a closed second adhesive layer. On the one hand, the fixing effect of the wearable ultrasonic patch is ensured, and on the other hand, the adhesive gel is confined in the inner cavity 8 to avoid overflow and insufficient gel, thereby improving the coupling effect.

[0069] In the present invention, the auxiliary positioning seat 2 and the sleeve seat 5 are both plate-shaped structures. Specifically, Figure 5 , Figure 6 and Figure 7 As shown, the auxiliary positioning seat 2 is symmetrically arranged on both sides of the sleeve 5, the auxiliary positioning seat 2 is consistent with the sleeve 5 in width, the auxiliary positioning seat 2 and the sleeve 5 are consistent in height and are combined to form a combined plate body 11, the combined plate body 11 is a rectangular parallelepiped, and the auxiliary positioning seat 2 and the sleeve 5 are flush with the ground.

[0070] like Fig.11 and Fig.12 As shown, a bottom groove 12 is provided at the bottom of the combined plate body 11, the depth of the bottom groove 12 is equal everywhere, the end of the bottom groove 12 extends to the auxiliary positioning seat 2, the patch body 1 fits the top of the bottom groove 12, and the outer edge of the patch body 1 is completely matched with the inner wall of the bottom groove 12, that is, a bottom groove 12 is opened at the bottom of the combined plate body 11, the bottom groove 12 opens downward, and the patch body 1 is arranged at the top of the bottom groove 12.

[0071] To prevent the patch body 1 from detaching from the top of the bottom groove 12 under the action of gravity, a third adhesive layer 13 is provided on the groove wall of the bottom groove 12 on the auxiliary positioning seat 2, and the edge of the patch body 1 is adhered to the third adhesive layer 13.

[0072] An inner cavity 8 is formed in the bottom groove 12. The inner cavity 8 is mainly for forming a second adhesive layer. Therefore, the thickness of the patch body 1 is smaller than the depth of the bottom groove 12. The inner cavity 8 is formed in the bottom groove 12 area at the bottom of the patch body 1. The inner cavity 8 must have a certain content volume for the solvent to enter and mix with the gel layer to form a second adhesive layer.

[0073] In the above embodiments, the gel layer is a soluble adhesive gel material, which is dissolved in the solvent to form a gel-like second adhesive layer after being mixed with a solvent (the solvent is generally water). The second adhesive layer not only has a certain degree of adhesion, but also has a better coupling effect.

[0074] In the present invention, the patch body 1 is composed of a common PDMS substrate layer, a flexible electrode layer, a circuit device layer, and an upper flexible substrate layer. The auxiliary positioning seat 2 and the sleeve seat 5 can be used in the preparation process of the above multiple layers. The following is the process of preparing different layers in the auxiliary positioning seat 2 and the sleeve seat 5:

[0075] Invert the auxiliary positioning seat 2 and the sleeve seat 5 so that the bottom groove 12 faces upward, clean the flexible silicon wafer substrate and place it in the bottom groove 12, and there is a certain distance between the outer wall of the flexible silicon wafer substrate and the inner wall of the bottom groove 12;

[0076] A layer of uncured PDMS (polydimethylsiloxane) is evenly coated on the flexible silicon substrate and air-dried to form a PDMS substrate layer;

[0077] Place metal electrodes on the PDMS substrate layer, apply low-temperature solder paste to the welding points shown on the electrode pattern, and place the piezoelectric unit, resistor, and capacitor at the connection of the metal electrodes;

[0078] Heating and curing: heating the uncured electrical components to melt the low-temperature solder paste, and then naturally cooling to complete the welding of the piezoelectric unit, resistor, capacitor and metal electrode to obtain the circuit component layer;

[0079] Pour PDMS into the bottom groove 12 so that it completely covers the above layers, and obtain the patch body 1 after natural curing.

[0080] The patch body 1 obtained through the above steps has been fixed in the bottom groove 12. At this time, an inner cavity 8 is formed above the patch body 1 in the bottom groove 12, and the inner cavity 8 faces upward. In the process of attaching the patch body 1 to the surface of the wearing area, the bottom groove 12 and the inner cavity 8 are both set downward.

[0081] The solvent enters the inner cavity 8 from the pore structure 9. In the present invention, the pore structure 9 adopts the following preferred embodiments, such as Figure 8 and Fig. 9 As shown, the hole structure 9 includes a clamping column 91 disposed on the auxiliary positioning seat 2 at the position of the bottom groove 12 and a through groove 92 disposed on the patch body 1;

[0082] The clamping column 91 passes through the through groove 92, the clamping column 91 fits with the inner wall of the through groove 92, and the height of the clamping column 91 is consistent with the depth of the through groove 92;

[0083] A first hole 93 is formed in the clamping column 91, and a second hole 94 is formed on the auxiliary positioning seat 2. The first hole 93 and the second hole 94 are connected and communicated, and the cross-sectional shapes and sizes of the first hole 93 and the second hole 94 are the same.

[0084] Specifically, the column 91 can be regarded as a pipeline, and the solvent passes through the second hole groove 94 and the first hole groove 93 in sequence and enters the inner cavity 8.

[0085] The first hole groove 93 and the second hole groove 94 are not only used for solvent injection, but also for the discharge of gas in the inner cavity 8. To achieve the discharge of gas, the first hole groove 93 and the second hole groove 94 form a vertical groove body, and the auxiliary positioning seat 2 is set to two. There are at least two corresponding vertical groove bodies, and the positions of the vertical groove bodies are opposite to each other. The solvent is injected into the position of one of the vertical groove bodies, and the gas in the inner cavity 8 is discharged from the other vertical groove body. The effective discharge of gas can ensure that the second adhesive layer is free of bubbles.

[0086] In the above embodiments, the function of the clamping column 91 is to serve as a pipeline for solvent injection and gas discharge. In addition, it can also position the patch body 1 in the horizontal direction. Specifically, in the process of preparing the patch body 1, the auxiliary positioning seat 2 and the sleeve 5 are needed. After the patch body 1 is prepared, the sleeve 5 is removed from the auxiliary positioning seat 2 to make the auxiliary positioning seat 2 in a flexible and adjustable state. This step is conducive to fixing the entire structure on the surface of the wearing area (the entire positioning process has a high degree of freedom, avoiding the situation where the positioning patch 3 is not in the right position after being affixed and needs to be readjusted). Since the auxiliary positioning seat 2 is flexible and adjustable at this time, the positioning patch 3 is affixed in a relatively horizontal and facing position. At this time, the patch body 1 may be bent, and the auxiliary positioning seat 2 is pulled to both sides to make the patch body 1 in a straight state. At this time, the sleeve 5 is re-installed between the auxiliary positioning seats 2 to facilitate the subsequent preparation of the second adhesive layer.

[0087] When the patient's body surface moves, the gel is easily squeezed out of the inner cavity 8. To avoid such a situation, the present invention provides a blocking structure. Specifically, a mounting groove 14 is provided on the auxiliary positioning seat 2 near the sleeve seat 5, and the mounting groove 14 is connected to the second hole groove 94;

[0088] like Fig. 9 As shown, the blocking structure 10 includes a blocking plate 101 disposed in the mounting groove 14 and a blocking bolt 102 disposed at the bottom of the blocking plate 101;

[0089] The blocking bolt 102 is inserted into the first hole groove 93 and the second hole groove 94 . The length of the blocking bolt 102 is equal to the sum of the depths of the first hole groove 93 and the second hole groove 94 . The outer wall of the blocking bolt 102 fits with the outer walls of the first hole groove 93 and the second hole groove 94 .

[0090] In a specific implementation, the blocking bolts 102 are aligned with the first hole groove 93 and the second hole groove 94 one by one, and are inserted into the first hole groove 93 and the second hole groove 94 , and the blocking plate 101 is also buckled in the installation groove 14 .

[0091] In order to facilitate the placement and removal of the blocking plate 101 in the installation groove 14, a curved groove can be opened on the blocking plate 101 so that a convex block is formed on the surface of the blocking plate 101 for easy lifting.

[0092] During the process of preparing the patch body 1 , the blocking plate 101 and the blocking plug 102 are installed at corresponding positions. When the solvent needs to be injected into the inner cavity 8 , the blocking plate 101 and the blocking plug 102 are removed.

[0093] The present invention utilizes the positioning component 4 to drive the auxiliary positioning seat 2 to move relative to the positioning sticker 3. The positioning component 4 mainly adopts the following preferred embodiments: Figure 1 and Figure 2 As shown, the positioning component 4 includes a first connection seat 41 connected to the auxiliary positioning seat 2 on a side away from the patch body 1, and a second connection seat 42 arranged on the side of the first connection seat 41;

[0094] A Velcro is provided on the side of the first connection seat 41 close to the second connection seat 42 , and a Velcro is provided on the side of the second connection seat 42 close to the first connection seat 41 , and the Velcro is attached to the Velcro.

[0095] The second connecting seat 42 is provided with a long groove 43, and the positioning sticker 3 is provided with a fourth adhesive layer 44;

[0096] An adjustment belt 45 is provided on the positioning sticker 3 , one end of the adjustment belt 45 is fixed on the positioning sticker 3 , and the other end of the adjustment belt 45 passes through the bottom of the long groove 43 , passes out from the top of the long groove 43 and is adhered to the fourth adhesive layer 44 .

[0097] By adjusting the sticking position of the end of the adjusting belt 45 on the fourth adhesive layer 44 , the position of the auxiliary positioning seat 2 relative to the positioning sticker 3 can be driven.

[0098] In practical applications, there may inevitably be irregularities on the surface of the wearing area, and the inner cavity 8 needs to be completely closed to achieve the corresponding "gel will not overflow" effect. Therefore, it is necessary for the auxiliary positioning seat 2 and the bottom of the sleeve 5 to be able to be positioned on the surface of the wearing area, and the adjustment process of the auxiliary positioning seat 2 requires that the auxiliary positioning seat 2 itself be in active contact with the surface of the wearing area. There is a certain contradiction between the above purposes. To resolve the contradiction, the present invention makes the following design: a release layer 15 is applied to the bottom of the first adhesive layer 7.

[0099] During the preparation process and the adjustment process of the auxiliary positioning seat 2, the release layer 15 is adhered to the first adhesive layer 7. Due to the existence of the release layer 15, there is only a small sliding friction between the bottom of the auxiliary positioning seat 2 and the surface of the wearing area, which will not hinder the movement of the auxiliary positioning seat 2 on the surface of the wearing area. After the adjustment is completed, the release layer 15 can be torn off, and pressure is applied to the whole to make the first adhesive layer 7 directly adhere to the surface of the wearing area. Among them, the release layer 15 is between the surface of the wearing area and the auxiliary positioning seat 2, and may not be easy to tear off. For this purpose, a traction line can be set on the release layer 15, and the release layer 15 can be torn off using the traction line.

[0100] In order to further ensure the sealing of the inner cavity 8, it is also necessary to make the auxiliary positioning seat 2 and the sleeve seat 5 tightly connected. For this, the present invention makes the following design: Fig.10 As shown, a card slot 16 is provided on the auxiliary positioning seat 2 near the sleeve seat 5, and a card block 17 is provided on the sleeve seat 5 near the auxiliary positioning seat 2, and the card block 17 fits with the card slot 16;

[0101] When the sleeve 5 is inserted downward into the auxiliary positioning seat 2, the clamping block 17 is clamped in the clamping groove 16 along the vertical direction;

[0102] The clamping block 17 includes a clamping portion 171 and a connecting portion 172 . The clamping portion 171 is connected to the connecting portion 172 . The connecting portion 172 is connected to the sleeve 5 . The width of the clamping portion 171 is greater than the width of the connecting portion 172 .

[0103] Under the engagement of the engaging portion 171 , the engaging block 17 cannot be separated from the engaging slot 16 . The design of the engaging block 17 and the engaging slot 16 can effectively ensure a tight connection between the auxiliary positioning seat 2 and the sleeve seat 5 .

[0104] In summary, the preparation and application process of the wearable ultrasound patch is as follows:

[0105] like Fig.11As shown, the auxiliary positioning seat 2 and the sleeve seat 5 are tightly connected to each other and inverted so that the bottom groove 12 faces upward, the flexible silicon wafer substrate is cleaned and placed in the bottom groove 12, and there is a certain distance between the outer wall of the flexible silicon wafer substrate and the inner wall of the bottom groove 12. A layer of uncured PDMS is evenly coated on the flexible silicon wafer substrate and air-dried to form a PDMS substrate layer; metal electrodes are placed on the PDMS substrate layer, and low-temperature solder paste is applied to the welding points shown on the electrode pattern, and piezoelectric units, resistors, and capacitors are placed at the connection points of the metal electrodes; heating and curing, the uncured electrical components are heated to melt the low-temperature solder paste, and the piezoelectric units, resistors, capacitors and metal electrodes are welded after natural cooling to obtain a circuit component layer, and PDMS is poured into the bottom groove 12 so that it completely wraps the above layers. After natural curing, the patch body 1 is obtained, and the gel precursor is poured onto the patch body 1 and cured to form a gel layer (such as Fig.12 shown);

[0106] Invert the auxiliary positioning seat 2 and the sleeve 5 again, with the bottom groove 12 facing downward, remove the sleeve 5 from the auxiliary positioning seat 2, and stick the positioning sticker 3 at a relatively horizontal and facing position. By adjusting the sticking position of the end of the adjustment belt 45 on the fourth adhesive layer 44, pull the auxiliary positioning seat 2 to both sides to make the patch body 1 in a straight state;

[0107] The sleeve 5 is reinstalled between the auxiliary positioning seats 2, the blocking plate 101 and the blocking plug 102 are removed, and a solvent is injected into one of the vertical slots. The gas in the inner cavity 8 is discharged from the other vertical slot. The injected solvent is mixed with the gel layer to form a gel-like second adhesive layer. At this time, the preparation and positioning of the entire patch body 1 are completed;

[0108] After the patch body 1 is fixed, the patch body 1 is used to monitor data.

[0109] The present invention also provides a data processing method for a wearable ultrasound patch, comprising the following steps:

[0110] Conduct body change monitoring experiments based on different body structure change states;

[0111] Acquire ultrasonic echo signals in different directions, convert the ultrasonic echo signals into electrical signals and transmit them to the signal processing module;

[0112] The signal processing module is used to filter and reduce noise of the received electrical signal;

[0113] Input multiple groups of body structure change states and processed electrical signals into a recurrent network model for training to obtain a body change association model;

[0114] The actual collected electrical signals are input into the body change association model to predict the actual state of body structure change.

[0115] The construction and training process of the recurrent network model specifically includes: creating a three-layer neural network including an input layer, a hidden layer, and an output layer; setting the training function, connection function, and output function of the hidden layer, connection layer, and output layer; setting the expected minimum error, maximum number of iterations, and learning rate of the network; inputting the training set into the recurrent network model and training; adjusting the weights of each layer in the recurrent network model according to the error; judging whether the recurrent network model converges, and completing the training after convergence; wherein, when the error is less than the expected minimum error, the algorithm converges; and when the maximum number of iterations is reached, the algorithm ends.

[0116] The above process is based on a recurrent network model to establish the relationship between the state of body structure changes and electrical signals, and is suitable for monitoring body changes, such as cervical curvature monitoring.

[0117] Ultrasonic monitoring can also be used to monitor body structures such as the heart. Specifically, wearable ultrasound is used to obtain echo ultrasonic signals from different directions of the target structure (heart), the echo ultrasonic signals are converted into electrical signals and input into the data processing module, the received electrical signal data is filtered and denoised, the received electrical signal data is back-projected, an ultrasonic image of the target structure is generated through an image reconstruction algorithm, and the corresponding parameters are calculated and processed based on the ultrasonic image.
