Abstract
Description
Technical Field
[0001] The present invention relates to the field of medical ultrasonic technology, and particularly to a medical ultrasonic long-term monitoring device. Background Art
[0002] 8% of the global death toll is caused by trauma. The incidence of chest trauma is very high, accounting for 10% - 15% of all traumas, and the direct death toll accounts for 25% of all trauma deaths; abdominal trauma is a relatively common severe trauma both in peacetime and wartime, and its incidence is about 0.4% - 1.8% of various injuries in peacetime. The treatment methods for traumatic diseases of thoracic organs, abdominal organs and the heart are rapid diagnosis and rapid treatment. Clinically, the rapid diagnosis of traumatic diseases of thoracic organs, abdominal organs and the heart mainly relies on examination means such as MRI, CT and ultrasound, to quickly detect traumatic diseases and the resulting pleural, peritoneal and pericardial effusions. Currently, bedside ultrasound is an important method for rapid disease diagnosis compared with MRI and CT. However, due to the relatively complex operation technology of ultrasound, the poor recognition of ultrasound images by clinicians, and the poor recognition accuracy of traumatic diseases and effusions, it largely depends on the diagnosis of ultrasound doctors.
[0003] Unexpected bleeding in trauma patients and postoperative patients is not rare clinically. According to incomplete statistics, the incidence of postoperative bleeding in the abdomen is about 0.5 - 3%, and the proportion of rebleeding after thoracic surgery is 1.25% - 1.94%. The diagnosis of rebleeding or delayed bleeding in postoperative patients mainly depends on the observation of the vital signs of patients by doctors and nurses. It is often only when the patient's vital signs are unstable that the possibility of postoperative rebleeding or delayed bleeding is considered. In this case, the clinical accurate determination of such patients often depends on the evaluation of bedside ultrasound by ultrasound doctors, which delays the diagnosis and treatment of patients to a certain extent. To sum up, currently in clinical practice, for pleural, peritoneal and pericardial effusions, it is mostly ultrasound doctors who go to the bedside to use mobile ultrasound equipment to judge whether there is effusion, while clinicians generally do not have the ability to recognize ultrasound images. At the same time, it is impossible for ultrasound doctors and clinicians to use existing ultrasound equipment to observe whether patients have effusion at the bedside 24 hours a day. Therefore, the present application provides a device that can timely, conveniently and real-time judge whether there is pleural effusion, peritoneal effusion and pericardial effusion and the change of the effusion volume in patients after trauma, surgery, etc., and can remind clinicians to guide clinical diagnosis and treatment, and at the same time does not depend on the judgment and diagnosis of clinicians and ultrasound doctors, so as to realize the long-term monitoring of the above diseases.

[0039] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.
[0040] Refer to Figure 1-21 , a medical ultrasonic long-term monitoring device, including a main unit 1 and a probe 2. A plurality of female connectors 4 for connecting different probes 2 are arranged on the side of the main unit 1. The probe 2 is connected with a sub-connector 3 through a data cable. The probe 2 is connected with the main unit 1 through the sub-connector 3 and the female connector 4. The main unit 1 includes an input / output module, an ultrasonic data processing module, an analysis module, a display module, and a recording module.
[0041] It can be understood that the input / output module serves as an interface for medical staff to interact with the device. The input function is used to set various parameters of the device. For example, the ultrasonic emission frequency, power, and scanning mode of the ultrasonic data processing module can be set, and the time interval for data collection during long-term observation (such as collecting once every 5 minutes) can also be set. The output function transmits information such as the operating state of the device and the data processing results to other modules or external devices. For example, the data collected by the ultrasonic data processing module is sent to the recording module for storage, or the judgment result on pleural effusion obtained by the analysis module is sent to the display module for display; The ultrasonic data processing module is used for ultrasonic transmission and reception. According to the parameters set by the input-output module, this module regularly transmits ultrasonic pulses to the patient's chest cavity through probe 2. The ultrasonic pulses propagate in the chest cavity and are reflected when encountering interfaces of different tissues and liquids. The ultrasonic data processing module receives these reflected ultrasonic signals, which contain rich information about the internal structure of the chest cavity. After receiving the ultrasonic signals, preprocessing is first carried out, including operations such as amplifying and filtering the signals. Amplification is to enhance weak reflected signals, and filtering is to remove external interference and noise signals generated by the device itself, improving the signal quality for accurate imaging and analysis in the subsequent process. The preprocessed ultrasonic signals are converted into ultrasonic images. The ultrasonic data processing module converts information such as the intensity and time delay of the reflected signals into grayscale images or color blood flow images according to different imaging algorithms. The resolution and clarity of the imaging directly affect the observation effect of pleural effusion; The analysis module is used for image feature analysis. The analysis module extracts features from the ultrasonic images transmitted from the ultrasonic data processing module. For the judgment of pleural effusion, it will focus on the grayscale features in the images, such as the grayscale difference between the effusion area and the surrounding tissues; texture features, such as the difference between the relatively uniform texture in the effusion area and the complex texture of the surrounding tissues; and shape features, such as the distribution shape of the effusion and the clarity of the boundary, etc. Based on the extracted image features, the analysis module uses a pre-set algorithm to judge pleural effusion. The algorithm is based on machine learning or deep learning models. For example, using a trained convolutional neural network model, the ultrasonic image is input into the model, and the model outputs a judgment result on whether there is pleural effusion according to the learned feature patterns. In addition to judging whether there is effusion currently, the analysis module can also analyze multiple groups of data collected within 24 hours to obtain the change trend of pleural effusion. For example, whether the effusion volume is gradually increasing, decreasing or remaining stable; The display module is used for real-time image display and display of the judgment results of the analysis module. During the long-term observation process, the display module receives the ultrasonic image data and diagnostic data transmitted from the ultrasonic data processing module and the analysis module in real time. It displays the internal structure of the chest cavity in an intuitive image form, and medical staff can see the echo situation of the chest cavity tissues and preliminarily judge the possibility of the existence of effusion. For example, the effusion area usually appears as a hypoechoic or anechoic area in the ultrasonic image. When the analysis module completes the judgment of pleural effusion, the display module will clearly display the result, such as "There is pleural effusion" or "No pleural effusion is found". If there is effusion, it can also display quantitative information such as the approximate range and depth of the effusion. At the same time, for some critical situations or situations that need special attention, such as changes in the effusion volume, the display module will give corresponding prompt information, such as "There is no obvious change in the pleural effusion volume on the left side"; The recording module is used for data acquisition and recording. According to the time interval set by the input / output module, the recording module receives the ultrasonic data collected by the ultrasonic data processing module. These data include ultrasonic images, relevant device parameters (such as ultrasonic frequency, gain, etc.), and acquisition time stamps. For example, each acquisition of data will be marked with a time stamp accurate to the second for subsequent time series analysis. And the recording module stores all the collected data in the local hard disk or cloud server. Local storage can ensure that data is not lost in case of network failure, while cloud storage facilitates access and data sharing among multiple devices and users. The stored data format follows the standard format for medical image storage to be compatible with other medical devices and information systems.
[0042] Specifically, the probe 2 is a flat square shape, and the wafer 201 is arranged on the largest surface of the probe 2. The wafer 201 is arranged in a matrix pattern (as Figure 20 shown), and the probe 2 uses a hard shell.
[0043] It can be understood that by setting the probe 2 as a flat square shape, it is convenient to fit on the patient's skin for a long time, reducing the impact of the probe 2 on the patient. The matrix layout of the wafers 201 enables more comprehensive data collection of the ultrasonic field in space, improving the image quality. At the same time, multiple scanning modes can be achieved through different combination methods.
[0044] Specifically, there are multiple anti-disconnection components 5 inside the host 1 for preventing the sub-connector 3 from loosening from the female connector 4. The anti-disconnection component 5 includes a clamping plate 501 fixed at the opposite ends of the sub-connector 3 and the female connector 4. A clamping groove for cooperating with the curved rod 502 is formed on the upper surface of the clamping plate 501. There are two clamping plates 501 in total, and they are symmetrically arranged at one end of the sub-connector 3. Two mounting plates 6 are fixedly connected inside the host 1. Both of the two mounting plates 6 are U-shaped, and the two mounting plates 6 are symmetrically arranged on both sides of the female connector 4. Bow-shaped curved rods 502 are rotatably arranged on the surfaces of the two mounting plates 6. One end of the curved rod 502 is fixed with a push plate 503. A spring for driving the curved rod 502 to disengage from the clamping groove is fixedly connected to the surface of the push plate 503. The other end of the spring is fixedly connected to the surface of the mounting plate 6. There are two groups of curved rods 502 in total, and they are symmetrically arranged on the surfaces of the two mounting plates 6. A plug rod 7 for pushing the push plate 503 is slidably arranged at one end of the sub-connector 3 close to the female connector 4.
[0045] It can be understood that when the sub-connector 3 is connected to the female connector 4, the sub-connector 3 drives the plug rod 7 to push the two push plates 503, so that the push plates 503 drive the curved rods 502 to rotate, and the middle part of the curved rods 502 is clamped in the clamping groove on the surface of the clamping plate 501, thereby avoiding the sub-connector 3 from loosening or even detaching from the surface of the female connector 4, resulting in signal transmission failure and affecting the long-term monitoring of the patient.
[0046] Specifically, a first limiting component 8 for limiting the insertion rod 7 is arranged inside the sub-connector 3. The first limiting component 8 includes an inclined rack 801 fixed inside the sub-connector 3. The inner end of the insertion rod 7 is rotatably connected with a limiting plate 802 through a connecting shaft. The limiting plate 802 is at the same height as the inclined rack 801. The limiting plate 802 is arc-shaped. A torsion spring for driving the other end of the limiting plate 802 to be clamped on the surface of the inclined rack 801 is sleeved on the surface of the connecting shaft. A spring for pushing the insertion rod 7 to slide outward is fixedly connected to the inner end of the insertion rod 7. A pressing block 803 slides at the inner end of the insertion rod 7. One end of the pressing block 803 extends out of one side of the sub-connector 3. The pressing block 803 is located between the limiting plate 802 and the spring. A push column is fixedly connected to the side of the pressing block 803 close to the limiting plate 802. The push column is located between the limiting plate 802 and the inclined rack 801.
[0047] It can be understood that the insertion rod 7 is pushed to slide outward by the spring, and the torsion spring drives the limiting plate 802 to be clamped on the surface of the inclined rack 801. Since the inclined teeth on the surface of the inclined rack 801 face the outer end of the insertion rod 7, therefore, when the insertion rod 7 slides outward, it is not restricted by the inclined rack 801, but the limiting plate 802 is clamped on the surface of the inclined rack 801, so that the insertion rod 7 can be prevented from automatically sliding into the sub-connector 3. By pressing the pressing block 803, the pressing block 803 and the push column drive the limiting plate 802 to disengage from the inclined rack 801, thereby releasing the limit on the insertion rod 7, facilitating the pulling of the insertion rod 7 into the sub-connector 3, so that the insertion rod 7 is separated from the push plate 503, and facilitating the pulling out of the sub-connector 3.
[0048] Specifically, a winding component 9 for storing the data cable of the probe 2 is arranged on the back of the main unit 1. The winding component 9 includes two winding disks 902 symmetrically sliding on the surface of a first guiding rod 901. The first guiding rod 901 is arranged inside the main unit 1. A through groove for moving the two winding disks 902 is arranged on the back of the main unit 1. The winding disk 902 is a semi-circular U-shaped plate. A plurality of rotating rods 903 are rotatably arranged on the inner wall of the winding disk 902. The plurality of rotating rods 903 are arranged in a circular array on the inner wall of the winding disk 902. A left-right threaded column 904 is rotatably arranged inside the main unit 1. Two moving blocks 905 are threadedly connected to the surface of the left-right threaded column 904. A spring for respectively pushing the two winding disks 902 onto the surfaces of the two moving blocks 905 is arranged between the two winding disks 902. The spring is sleeved on the surface of the first guiding rod 901. One end of the left-right threaded column 904 extends out of the main unit 1. A rotating handle is fixedly connected to the outer end of the left-right threaded column 904.
[0049] It can be understood that by setting two winding disks 902, it is convenient to wind the redundant data cables of the probe 2 around the surfaces of the two winding disks 902 to store the data cables, preventing the overly long data cables from making the area near the hospital bed messy and preventing the caregiver from accidentally pulling the data cables and causing the probe 2 to detach from the patient's skin. By driving two moving blocks 905 away from or close to each other through the positive and negative threaded columns 904, and the springs pushing the winding disks 902 to always abut against the surfaces of the two moving blocks 905, the maximum distance between the two winding disks 902 can be adjusted to keep the winding length of the data cables within a suitable range. At the same time, when the patient moves slightly, the tightened data cables can pull the two winding disks 902 closer to each other, thereby automatically releasing the corresponding length of the data cables to give the patient a certain amount of room for movement. Under the action of multiple rotating rods 903, the friction between the data cables and the winding disks 902 is reduced, facilitating the movement of the data cables on the surfaces of the winding disks 902.
[0050] Specifically, an adsorption assembly 10 for fixing the host 1 on the desktop is provided at the bottom of the host 1. The adsorption assembly 10 includes a plurality of suction cups 1001 fixed to the bottom of the host 1. The upper ends of the plurality of suction cups 1001 are all communicated through a connecting pipe 1002. One end of the connecting pipe 1002 is provided with a one-way exhaust valve 1003. The one-way exhaust valve is arranged outside the host 1. A pressing valve 1004 for air intake is provided on the surface of the connecting pipe 1002. The pressing valve 1004 is pressed through a top rod 1005. A spring for pulling the top rod 1005 away from the pressing valve 1004 is sleeved on the surface of the top rod 1005. The top rod 1005 slides inside the host 1, and one end of the top rod 1005 away from the pressing valve 1004 extends out of the back surface of the host 1.
[0051] It can be understood that by pressing the host 1 on the desktop, the plurality of suction cups 1001 are deformed, and the air in the suction cups 1001 is discharged through the connecting pipe 1002 and the one-way exhaust valve 1003, causing the suction cups 1001 to generate negative pressure, thereby fixing the host 1 on the desktop and preventing the data cables from pulling the host 1 to cause displacement and resulting in uncontrollable impacts. By pressing the top rod 1005, the top rod 1005 drives the pressing valve 1004 to allow air to enter the connecting pipe 1002, so that the plurality of suction cups 1001 intake air to achieve air pressure balance, facilitating the lifting of the host 1.
[0052] Specifically, a plurality of clamping components 11 for clamping the data cable are arranged on one side of the main body 1 close to the female connector 4. The clamping component 11 includes a first clamping ring 1101 fixed to the back of the main body 1 and a second clamping ring 1102 rotatably arranged inside the main body 1. The clamping end of the second clamping ring 1102 extends out of the back of the main body 1. The second clamping ring 1102 is located below the first clamping ring 1101. An inclined block 1103 is fixedly connected to the inner end of the second clamping ring 1102. The inclined surface of the inclined block 1103 faces the insertion rod 7 and is located on the moving track of the insertion rod 7. A spring for driving the separation of the second clamping ring 1102 and the first clamping ring 1101 is fixedly connected to the inner end of the second clamping ring 1102. The clamping ends of the first clamping ring 1101 and the second clamping ring 1102 are both semi-circular rings.
[0053] It can be understood that when the sub-connector 3 is connected to the mother-connector 4, the sub-connector 3 drives the insertion rod 7 to insert into the main body 1. By pushing the inclined block 1103 with the insertion rod 7, the inclined block 1103 moves downward, thereby driving the second clamping ring 1102 to rotate. With the cooperation of the first clamping ring 1101, the end of the data cable close to the sub-connector 3 is clamped, avoiding the pulling force generated at the end of the data cable close to the sub-connector 3 when the two winding discs 902 store the data cable from being transmitted to the connection between the sub-connector 3 and the mother-connector 4, resulting in damage to the sub-connector 3 and the mother-connector 4 due to long-term stress. When the sub-connector 3 is separated from the mother-connector 4, the insertion rod 7 disengages from the inclined block 1103, and the spring drives the second clamping ring 1102 to separate from the first clamping ring 1101, facilitating the removal of the data cable.
[0054] Specifically, a fixing member 12 for fixing the probe 2 on the patient's skin surface is arranged on the surface of the probe 2. The fixing member 12 includes an inner frame cooperating with the probe 2 and an edge for pasting on the patient's skin. An adhesive layer and a film for protecting the adhesive layer are arranged on the contact surface between the edge and the skin. The probe 2 is clamped inside the fixing member 12 through the second limiting component 15, and a storage cavity 13 for storing the coupling agent is formed between the probe 2 and the skin inside the fixing member 12. A discharge hole 14 is formed on one side of the fixing member 12 close to the second limiting component 15, and the discharge hole 14 corresponds to the position of the storage cavity 13.
[0055] It can be understood that by arranging the adhesive layer, it is convenient to paste the fixing member 12 on the patient's skin. By arranging the storage cavity 13, it is convenient to store the coupling agent, avoiding the need to apply the coupling agent multiple times during the long-term monitoring process of the probe 2. By the cooperation of the fixing member 12 and the second limiting component 15, the probe 2 is fixed on the patient's skin to achieve the purpose of long-term monitoring. By arranging the discharge hole 14, it is convenient to discharge the excess coupling agent.
[0056] Specifically, the second limiting assembly 15 includes a limiting block 1501 fixed to the side of the probe 2 away from the data line, a groove 1502 is provided on the inner frame surface of the fixing member 12, a square guide rod 1503 is fixedly connected to the inside of the fixing member 12, and the square guide rod 1503 slides on one end of the groove 1502 close to the limiting rod 1504, and the limiting rod 1504 is provided with an inclined surface on one end of the groove 1502, a limiting groove is provided on the side of the limiting block 1501 close to the limiting rod 1504, and a sleeve is provided on the surface of the square guide rod 1503 for driving the limiting rod 1504. The positioning rod 1504 is inserted into the spring in the limiting groove on the surface of the limiting block 1501, and a lever is arranged on the side of the limiting rod 1504. A placement groove 17 for placing the data cable is provided on the side of the fixing member 12 away from the groove 1502. A pressure plate 18 is rotatably connected to one side of the fixing member 12 where the placement groove 17 is provided, and a clamping column 19 is fixed thereto. The pressure plate 18 and the clamping column 19 are respectively arranged on both sides of the placement groove 17. An arc groove for cooperating with the data cable and a clamping groove for cooperating with the clamping column 19 are provided on the surface of the pressure plate 18, and the clamping groove and the clamping column 19 are interference fit.
[0057] It can be understood that when the probe 2 is placed in the inner frame of the fixing part 12, the depth of the groove 1502 and the placement groove 17 is used to limit the height of the probe 2, thereby forming a storage cavity 13. At the same time, after the limit block 1501 enters the groove 1502, the limit rod 1504 is driven by the spring to be inserted into the surface of the limit block 1501 to fix the probe 2. Through the cooperation of the pressure plate 18 and the card column 19, the pressure plate 18 fixes one end of the data line of the probe 2. By limiting and fixing the two ends of the probe 2 respectively, the probe 2 is prevented from shaking in the fixing part 12 and affecting the monitoring effect. By toggling the toggle rod, the limit rod 1504 is driven to slide into the inside of the fixing part 12, so that the limit rod 1504 is separated from the limit block 1501, which is convenient for taking the probe 2 out of the fixing part 12.
[0058] Specifically, a closing component 16 for closing the discharge hole 14 is provided on the side of the fixing member 12 close to the discharge hole 14. The closing component 16 includes a cover plate 1601 fixed to the side of the limiting rod 1504 close to the edge through a connecting rod. A rubber pad 1602 is fixedly connected to the side of the cover plate 1601 close to the discharge hole 14, and a baffle 1603 is fixedly connected to the side of the edge away from the adhesive layer. The cover plate 1601 and the rubber pad 1602 slide between the baffle 1603 and the inner frame.
[0059] It can be understood that when the limit rod 1504 slides toward the side of the limit block 1501, the cover plate 1601 is driven to slide between the baffle 1603 and the inner frame through the connecting rod, thereby facilitating the closing of the discharge hole 14, thereby preventing the coupling agent from flowing out of the discharge hole 14 during long-term monitoring, resulting in insufficient coupling agent in the storage cavity 13, creating a cavity, and affecting the detection of the probe 2.
[0060] Embodiment 2.
[0061] Different from the foregoing embodiments: Specifically, the wafers 201 of the probe 2 are arranged in a cross pattern (as Figure 21 shown).
[0062] It can be understood that while reducing the number of wafers 201 to lower costs, the wafers 201 arranged in a cross pattern can transmit and receive ultrasonic signals in two mutually perpendicular directions without affecting the spatial coverage of the ultrasonic field.
[0063] Embodiment III.
[0064] Different from the foregoing embodiments: Specifically, the probe 2 uses a flexible housing, and the edges of the fixing member 12 are made of flexible material.
[0065] It can be understood that by using a flexible housing, the fitting degree between the probe 2 and the fixing member 12 can be improved, and at the same time, the detection requirements for different parts of the patient can be met. By using flexible materials for both the probe 2 and the edges of the fixing member 12, the comfort of the patient during wearing can be improved.
[0066] In the present invention, the host 1 is fixed on the desktop beside the patient through the adsorption assembly 10, and the sub-joint 3 is inserted into the corresponding mother-joint 4. The anti-loosening assembly 5 is used to prevent the sub-joint 3 from loosening or even detaching from the surface of the mother-joint 4, which may lead to signal transmission failure. Meanwhile, the data cable of the probe 2 is placed between the first clamping ring 1101 and the second clamping ring 1102. When the sub-joint 3 is inserted, the first clamping ring 1101 and the second clamping ring 1102 clamp and fix the data cable. Then, the fixing member 12 is pasted on the patient's body surface. The coupling agent is applied in the storage cavity 13 of the fixing member 12, and the probe 2 is placed into the fixing member 12. Under the action of the second limiting assembly 15 and the clamping plate 501, the two ends of the probe 2 are respectively limited and fixed, so as to prevent the probe 2 from shaking in the fixing member 12 and affecting the monitoring effect. Meanwhile, when the limiting block 1501 enters the groove 1502, the limiting block 1501 pushes the limiting rod 1504 into the interior of the fixing member 12. At the same time, it drives the cover plate 1601 and the rubber pad 1602 to separate from the discharge hole 14, so that the excess coupling agent flows out from the discharge hole 14. Then, the spring pushes the cover plate 1601 and the rubber pad 1602 to reset and close the discharge hole 14, preventing the coupling agent from flowing out of the discharge hole 14 during the long-term monitoring process, resulting in insufficient coupling agent in the storage cavity 13 and generating an air cavity, which affects the detection of the probe 2. Then, the excess data cable is wound around the surfaces of the two winding disks 902. Through the positive and negative threaded column 904, the maximum distance between the two winding disks 902 is adjusted to keep the winding length of the data cable within a suitable range. The various parameters of the device are set through the input-output module, such as the ultrasonic emission frequency, power, scanning mode, etc. of the ultrasonic data processing module. The patient is monitored over a long period through the ultrasonic data processing module and the probe 2. The analysis module extracts features from the ultrasonic images transmitted by the ultrasonic data processing module and determines whether there is pleural effusion. The result is directly displayed by the display module, which is convenient for clinicians to visually view the monitoring situation and take corresponding rescue measures in a timely manner.
