Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a wearable ultrasound monitoring device for respiratory muscles. Background Technology

[0002] Critically ill patients typically have severe conditions that progress rapidly. Therefore, continuous, real-time monitoring is crucial for timely detection and prompt intervention. Wearable ultrasound patches can monitor cardiac function and blood pressure changes in critically ill patients in real time and continuously. This non-invasive monitoring method avoids the risk of secondary iatrogenic infections associated with traditional invasive monitoring. Furthermore, wearable ultrasound patches can non-invasively track other vital signs and physiological signals deep within the body, allowing doctors to gain a more comprehensive understanding of the critically ill patient's condition. By continuously monitoring the patient's physiological data, doctors can promptly detect changes in the patient's condition, adjust treatment plans, and improve treatment outcomes.

[0003] For example, application publication number CN117898765A, entitled "A Wearable Ultrasonic Patch and Signal Processing Method for Intensive Care," includes: an adhesive material layer for attaching to the patient's skin surface; a matching layer for providing an acoustic impedance gradient; a sound-generating layer for generating ultrasound waves; and a backing layer for suppressing ringing effects. The matching layer is a double-layer acoustic matching layer. The wearable ultrasonic patch is manufactured by sequentially and tightly bonding the adhesive material layer, matching layer, sound-generating layer, electrode layer, and backing layer. Using an optimized multi-section Simpson method, continuous and accurate vital signs such as cardiac ejection fraction are obtained. After signal processing, and assisted by a wireless alarm system, it can be applied in intensive care.

[0004] Respiratory muscle function is one of the important monitoring indicators for critically ill patients. The diaphragm is the most important inspiratory muscle in the human body, responsible for the main inspiratory function during normal breathing. When patients experience difficulty breathing due to changes in their condition, the intercostal muscles, as accessory respiratory muscles, begin to work. Therefore, monitoring the function of the diaphragm and intercostal muscles in critically ill patients is an important indicator for evaluating their respiratory status. Currently, most clinical methods assess respiratory muscle function by calculating the thickening rate of the diaphragm and intercostal muscles. There is no suitable wearable ultrasound patch that can monitor the function of the respiratory muscles in patients. Utility Model Content

[0025] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0026] like Figure 1-4 As shown, the wearable ultrasonic monitoring device for respiratory muscles provided by this utility model includes an ultrasonic patch body 1 and a patch connecting member 2. The ultrasonic patch body 1 includes an adhesive material layer 11, a matching layer 12, a sound-emitting layer 13, and a backing layer 14 arranged sequentially from bottom to top. The adhesive material layer 11, the matching layer 12, the sound-emitting layer 13, and the backing layer 14 are tightly bonded together in sequence. A wireless communication component 15 is provided on the upper surface of the backing layer 14. The matching layer 12 and the sound-emitting layer 13 have the same shape and area. The adhesive material layer 11 and the backing layer 14 have the same shape and area. The area of ​​the backing layer 14 is larger than the area of ​​the sound-emitting layer 13. The patch connecting member 2 includes a circumferential connector 21 arranged sequentially along the lower surface of the backing layer 14. The circumferential connector 21 surrounds the matching layer 12 and the sound-emitting layer 13 inside it. An adhesive connector 22 is provided at the bottom of the circumferential connector 21. The adhesive material layer 11 is connected to the adhesive connector 22. The middle position of the adhesive material layer 11 is bonded and connected to the matching layer 12.

[0027] Specifically, the ultrasonic patch body 1 includes, from bottom to top, an adhesive material layer 11, a matching layer 12, a sound-generating layer 13, and a backing layer 14. The adhesive material layer 11 is used to adhere to the patient's skin surface. The adhesive material layer 11 can be a polymer adhesive material. The matching layer 12 is used to provide an acoustic impedance gradient. The matching layer 12 provides the necessary acoustic impedance gradient so that the acoustic energy of the transducer can pass smoothly through the body tissue and the reflected sound waves (returning echoes) can return to the transducer for detection. The sound-generating layer 13 is used to generate ultrasonic waves. The sound-generating layer 13 includes a tightly fitted electrode layer and a piezoelectric ceramic layer. The backing layer 14 is used to suppress the ringing effect and prevent the echoes and ringing effects of the rearward emitted sound waves from returning to the sensor. The wireless communication device 15 is disposed on the upper surface of the backing layer 14. The wireless communication device 15 enables the transmission of detection data and the signal processing system to process the signal. This is prior art (detailed description has been provided in the application documents cited in the background art), and will not be repeated here.

[0028] In actual use, the ultrasonic patch body 1 is reused, and the adhesive material layer 11 is adhered to the respiratory muscles of different patients, which poses a risk of cross-infection. The improvement of this embodiment compared with the prior art is that a patch connecting member 2 is provided on the existing ultrasonic patch body 1, so that the adhesive material layer 11 can be replaced. In this way, after the ultrasonic patch body 1 has finished monitoring a patient, the adhesive material layer 11 on the ultrasonic patch body 1 is replaced, and then it is used to monitor another patient, thus avoiding the phenomenon of cross-infection.

[0029] In this embodiment, the adhesive material layer 11, the matching layer 12, the sound-emitting layer 13, and the backing layer 14 are sequentially and tightly bonded together. All of these layers have the same shape, but the matching layer 12 and the sound-emitting layer 13 have the same area and are aligned and connected. The adhesive material layer 11 and the backing layer 14 have the same area, but their areas are larger than those of the matching layer 12 and the sound-emitting layer 13. The sound-emitting layer 13 is fixed in the middle of the backing layer 14, and the matching layer 12 is aligned and fixedly connected to the sound-emitting layer 13. Thus, the backing layer 14 forms a circumferential extension relative to the sound-emitting layer 13 and the matching layer 12. The patch connecting member 2 is disposed along this circumferential extension to form a circumferential connector. 21. The shape of the circumferential connector 21 can be annular or other shapes. The interior of the circumferential connector 21 forms a receiving cavity. The matching layer 12 and the sound-emitting layer 13 are located in the receiving cavity formed by the circumferential connector 21. The thickness of the circumferential connector 21 is slightly less than the sum of the thicknesses of the matching layer 12 and the sound-emitting layer 13, so that a portion of the matching layer 12 extends out from the circumferential connector 21. An adhesive connector 22 is provided at the bottom of the circumferential connector 21. The adhesive material layer 11 is circumferentially bonded and fixed to the adhesive connector 22. The middle part of the adhesive material layer 11 can be bonded to the matching layer 12 or not. Since a portion of the matching layer 12 extends out from the circumferential connector 21, the matching layer 12 and the adhesive material layer 11 can fit tightly together.

[0030] The wearable ultrasonic respiratory muscle monitoring device provided by this utility model includes an ultrasonic patch body 1 and a patch connecting member 2. The ultrasonic patch body 1 includes, from bottom to top, an adhesive material layer 11, a matching layer 12, a sound-emitting layer 13, and a backing layer 14. A wireless communication component 15 is provided on the upper surface of the backing layer 14. The patch connecting member 2 includes a circumferential connector 21 arranged circumferentially along the lower surface of the backing layer 14. The circumferential connector 21 surrounds the matching layer 12 and the sound-emitting layer 13 inside it. An adhesive connector 22 is provided at the bottom of the circumferential connector 21. Layer 11 is connected to adhesive connector 22, and the middle position of adhesive material layer 11 is bonded to matching layer 12. In this way, during use, the ultrasonic patch body 1 can be attached and fixed to the patient's respiratory muscles for monitoring through adhesive material layer 11. When the ultrasonic patch body 1 is removed and used on another patient, adhesive material layer 11 can be removed and replaced with another one. The replaced adhesive material layer 11 can be bonded and fixed together with patch connector 2 to form a fixation, and then it can continue to be used, avoiding cross-infection caused by different patients using the same ultrasonic patch body 1.

[0031] In this embodiment, preferably, the adhesive material layer 11 is provided with strip-shaped adhesive portions 113 that are connected to the adhesive connector 22. The strip-shaped adhesive portions 113 are arranged sequentially along the circumference of the adhesive material layer 11, and the strip-shaped adhesive portions 113 are correspondingly arranged with the adhesive connector 22. In this way, during use, the strip-shaped adhesive portions 113 can be connected with the adhesive connector 22, so that the adhesive material layer 11 is bonded and fixed to the bottom of the patch connector 2. When the adhesive material layer 11 is replaced, the replaced adhesive material layer 11 can also be bonded and fixed to the adhesive connector 22.

[0032] In this embodiment, preferably, the circumferential connector 21 is provided with a plurality of connecting structures 23 along the circumferential direction, and the adhesive material layer 11 is provided with strip-shaped fasteners 111. The strip-shaped fasteners 111 are provided one-to-one with the connecting structures 23. The connecting structure 23 includes a strip-shaped opening 24 formed on the circumferential connector 21 and the backing layer 14. An upper adhesive fastening part 25 is provided on one side of the strip-shaped opening 24. The strip-shaped fastener 111 includes a connecting strip 112 provided on the adhesive material layer 11. The connecting strip 112 can pass through the strip-shaped opening 24, and the connecting strip 112 is provided with a folded adhesive part corresponding to the upper adhesive fastening part 25. For example, the adhesive material The material layer 11, matching layer 12, sound-emitting layer 13, and backing layer 14 are all square. The circumferential connector 21 is formed by connecting four strips. Each strip has a strip opening 24. The backing layer 14 has four corresponding strip openings 24. The adhesive material layer 11 has four connecting strips 112, which correspond one-to-one with the four strip openings 24. During use, the four connecting strips 112 can be inserted into the strip openings 24 one-to-one. The upper end of the connecting strip 112 extends out of the strip opening 24 and is then bent, so that the folded edge adhesive part is bonded and fixed together with the upper adhesive fixing part 25.

[0033] In this embodiment, preferably, it also includes an annular mounting body 3, which is fixedly connected to the upper surface of the backing layer 14. The interior of the annular mounting body 3 forms a mounting cavity for mounting the wireless communication component 15. A power supply module is also provided in the mounting cavity, so that the wireless communication component 15 and the power supply module are mounted inside the annular mounting body 3.

[0034] In this embodiment, preferably, a circular rotating component 4 is also included. The circular rotating component 4 includes an operating body 41 and a rotating body 42 connected to each other. An internal thread is provided on the inner wall of the annular mounting body 3, and an external thread matching the internal thread is provided on the circumferential side wall of the rotating body 42. A flexible pressing component is provided at the bottom of the rotating body 42, and the flexible pressing component presses against the wireless communication component 15. In this way, during use, the user can rotate the circular rotating component 4 by holding the operating body 41. When the circular rotating component 4 rotates into the mounting cavity, the flexible pressing component presses down on the wireless communication component 15 and the backing layer 14, so that the matching layer 12 is in close contact with the adhesive material layer 11. Conversely, when the matching layer 12 protrudes more from the receiving cavity of the circumferential connecting body 21, the circular rotating component 4 can be rotated in the opposite direction, so that the pressure of the flexible pressing component on the wireless communication component 15 and the backing layer 14 is reduced, so that the adhesive material layer 11 can be attached to the patient's adhesive material layer 11.

[0035] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
