Description

Technical Field

[0001] The invention relates to the technical field of ultrasound, and in particular to a dynamic ultrasound measuring device for fetal growth monitoring. Background Art

[0002] Fetal ultrasound is an important examination performed during pregnancy. It uses ultrasound technology to evaluate the growth and development of the fetus, detect congenital malformations and abnormalities, evaluate the condition of the uterus and placenta, and monitor the overall health of the mother and fetus. Therefore, pregnant women need to undergo fetal ultrasound examinations regularly during pregnancy to understand the health of the fetus.

[0003] During the fetal ultrasound examination, umbilical blood flow monitoring uses ultrasonic technology to evaluate the blood flow conditions in the fetal umbilical cord. It can obtain indicators such as the ratio of the highest blood flow velocity in systole to the lowest blood flow velocity in diastole (S / D value), resistance index (RI) and pulsatility index (PI). These indicators can not only evaluate the intrauterine development of the fetus, predict the safety of the fetus in the womb, guide clinical decisions and monitor placental function, but also assist in the diagnosis of other diseases. Therefore, umbilical blood flow monitoring is extremely important in the fetal ultrasound examination process.

[0004] When monitoring umbilical cord blood flow in existing fetal ultrasound, the ultrasound probe is usually placed on the surface of the pregnant woman's abdominal wall. At the same time, the position of the ultrasound probe needs to be opposite to the position of the fetal heart for auscultation (to avoid interference of the fetal heart beat on the umbilical cord blood flow signal), and it is aimed at the umbilical artery segment to be detected, so as to clearly capture the blood flow signal of the umbilical artery, thereby accurately evaluating the blood circulation of the fetus. Due to the different thickness of the pregnant woman's abdominal fat and the position of the fetus in the uterus, it may be necessary to repeatedly change the detection angle between the umbilical cord and the probe to find the best monitoring position, which helps to display the umbilical cord blood flow waveform more clearly, improve the reliability of the monitoring results, and ensure that the physician can judge the health status of the fetus.

[0005] However, during ultrasound imaging, it is necessary to ensure that the ultrasound probe is in close contact with the skin, so necessary pressure needs to be applied to ensure the quality of the ultrasound image, and the probe needs to be fixed for a certain period of time. For physicians with poor experience, it takes more time to adjust the measurement, and when a clear ultrasound image of a certain position is observed, the ultrasound image is difficult to reproduce due to the displacement of the pregnant woman's body surface tissue due to the changes in the physician's hands. At the same time, the safety of ultrasound detection by existing handheld probes is relatively high, but ultrasound collection for a long time will still cause health problems for physicians, such as local finger joint pain and other musculoskeletal diseases, affecting the hand stability during ultrasound detection. And during the use of the ultrasound probe, the ultrasound probe needs to continuously transmit and receive ultrasonic signals. This process consumes electrical energy and generates a certain amount of heat, which will also have a certain impact on the stability of the physician's hand. Therefore, the present invention provides a dynamic ultrasonic measurement device for assisting physicians in maintaining the detection position, so as to achieve clear capture of umbilical cord blood flow monitoring and monitor fetal growth. Summary of the invention

[0006] To solve the above problems, the present invention provides a dynamic ultrasound measurement device for fetal growth monitoring, which reduces the difficulty of fixing the probe of ultrasound monitoring and assists doctors in maintaining the position of the ultrasound probe to ensure that the blood flow signal of the umbilical artery is clearly captured.

[0007] In order to achieve the above-mentioned purpose, the technical scheme of the present invention is as follows: a dynamic ultrasonic measuring device for fetal growth monitoring comprises an ultrasonic probe body, a gripping handle is disposed on the outer cover of the ultrasonic probe body, and the gripping handle is clearance-matched with the ultrasonic probe body; a driving mechanism for pushing the ultrasonic probe body to move is disposed in the gripping handle;

[0008] A plurality of adjustment rods are fixedly connected around the gripping handle, and rollers are hinged at the ends of the adjustment rods away from the gripping handle;

[0009] It also includes a processing center. A plurality of first pressure sensors are fixedly connected to the top of the gripping handle. The first pressure sensors are used to measure the real-time pressure value when the gripping handle is in contact with the body surface of the pregnant woman, and send the real-time pressure value to the processing center. The processing center is used to send pressure instructions and rotation instructions to the driving mechanism based on the real-time pressure value.

[0010] The technical principles of the above scheme are as follows:

[0011] An adjustment rod is used to support the ultrasound probe body instead of human hands, and the real-time pressure value is used to control the driving mechanism, so as to make full contact with the ultrasound probe body during fetal ultrasound detection on behalf of the doctor, and make corresponding rotation adjustments to replace the doctor's rotation control.

[0012] The above scheme has the following beneficial effects:

[0013] 1. In this solution, the gripping handle is supported by an adjustment rod to ensure that the ultrasound probe body remains vertical to the pregnant woman's body surface during use, thereby providing a guarantee for the stability of subsequent ultrasound image acquisition.

[0014] 2. Compared with the prior art, this solution utilizes a driving mechanism instead of manual pressure or control, which reduces the medical staff's need for fetal ultrasound experience. It only requires the grip handle and the ultrasound probe body to move, reducing the difficulty of operation.

[0015] Furthermore, a slot is provided on the gripping handle, the slot is located between adjacent adjusting rods, the ultrasonic probe body is located in the slot, and the ultrasonic probe body and the slot are gap-matched.

[0016] Beneficial effect: The ultrasonic probe body is provided through the card slot, so that the ultrasonic probe can be easily installed and taken out.

[0017] Furthermore, a support rod is slidably matched on the adjusting rod, and the support rod and the adjusting rod are arranged vertically; the roller is located at one end of the support rod away from the adjusting rod, and a spring support is provided between the support rod and the adjusting rod.

[0018] Beneficial effect: The spring provides a deformation space, so that when the roller contacts the body surface of the pregnant woman, the spring pushes the roller to maintain close contact with the body surface of the pregnant woman.

[0019] Furthermore, the driving mechanism includes a plurality of driving members and an adsorption plate for adhering the ultrasonic probe body, the adsorption plate is slidably matched with the holding handle, and the ultrasonic probe body rotates around the adsorption plate; the driving members are symmetrically arranged around the card slot, the driving members are fixedly connected to the holding handle, the output end of the driving member is slidably matched with the holding handle, and the output end of the driving member is fixedly connected to an inclined contact block, and the contact block is located in the card slot.

[0020] Beneficial effect: The driving member drives the contact block to push the ultrasound probe body in the slot to achieve pressure detection between the ultrasound probe body and the pregnant woman's body surface. At the same time, the adsorption plate provides a rotation point for the ultrasound probe body, and then the different extension lengths of the driving member are used to push the ultrasound probe body to rotate around the adsorption plate, thereby realizing the adjustment of the detection angle between the umbilical cord and the ultrasound probe body.

[0021] Furthermore, a second pressure sensor is provided between the spring and the support rod, and the second pressure sensor is used to measure the feedback force when the support rod contacts the body surface of the pregnant woman, and send the feedback force to the processing center;

[0022] The processing center is used to mark the feedback force based on the position of adjacent support rods to form different reference data sets for storage; the difference is calculated based on the feedback force in the reference data set, and then the difference is compared with the set displacement value; if the difference is greater than the displacement value, the position of the support rod with large feedback force in the reference data set is obtained and marked as the lifting direction, and then a rotation instruction is sent to the driving mechanism based on the lifting direction, and the driving mechanism controls the rotation direction of the ultrasound probe body based on the rotation instruction; if the difference is less than the displacement value, the processing center compares the real-time pressure value with the set standard value, and if the real-time pressure value is greater than the standard value, a maintenance instruction is sent to the driving mechanism; if the real-time pressure value is less than the standard value, a pressure instruction is sent to the driving mechanism.

[0023] Beneficial effects: Through the indication of the feedback force on the support rod, the lifting direction has been confirmed to control the rotation angle of the ultrasound probe body, so as to ensure that the ultrasound probe body is in a vertical state with the body surface of the pregnant woman, provide basic angle guarantee, and facilitate subsequent rotation and adjustment of the ultrasound probe body to point to the umbilical cord, which helps to display the umbilical blood flow waveform more clearly and improve the reliability of the monitoring results.

[0024] Furthermore, the processing center is also used to compare the difference corresponding to the feedback force in the data set, and the processing center uses the basic angle corresponding to the displacement value as a reference; when the difference is greater than the displacement value, the adjustment value between the difference and the displacement value is calculated, and the processing center converts the adjustment value into an adjustment angle, and generates a rotation command to the drive mechanism based on the adjustment angle.

[0025] Beneficial effect: The basic angle corresponding to the displacement value is used as a reference to provide a comparison for the subsequent adjustment angle generation, thereby providing basic parameters for controlling the drive mechanism and improving the accuracy of the ultrasound probe body during rotation.

[0026] Furthermore, an isolation layer for isolating ultrasonic radiation is provided at the bottom of the gripping portion and in the card slot.

[0027] Beneficial effect: The ultrasonic waves generated during the operation of the ultrasonic probe body are isolated by the isolation layer, so as to reduce the impact of long-term ultrasonic collection on the health of doctors.

[0028] Furthermore, a plurality of heating cavities are provided on both sides of the card slot, and the heating cavities are arranged in a ring shape with the gripping handle as the center. A plurality of heat-conducting layers are provided on one side of the card slot close to the ultrasonic probe body, and the heat-conducting layers are connected to the heating cavities.

[0029] Beneficial effect: The heat generated during the operation of the ultrasound probe body is guided through the heat-conducting layer to heat the gripping handle, making it easier for doctors to use the probe in winter and improving the comfort of doctors during use.

[0030] Furthermore, a deformable rubber block is fixedly connected around the slot, and the ultrasonic probe is connected to the holding handle through the rubber block.

[0031] Beneficial effect: The ultrasonic probe body is clamped by the rubber block to prevent the ultrasonic probe body from falling out of the clamping slot, thereby improving stability during use.

[0032] Furthermore, a plurality of hidden cavities are formed on the gripping handle, each of which is provided with a shielding plate that is rotatably matched with the gripping handle, and the hidden cavities and the adjusting rod are on the same horizontal line; the adjusting rod is rotatably matched with the gripping handle, and the top of the support rod is threadedly connected with the adjusting rod.

[0033] Beneficial effect: The hidden cavity is provided to provide space for placing the adjusting rod, so that the adjusting rod can be stored inside when the device is not in use, thereby reducing the occupied space and facilitating the storage of the gripping handle.

[0034] Additional aspects and advantages of the present invention will be given in part in the following description and in part will be obvious from the following description, or will be learned through practice of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0043] The following is further described in detail through specific implementation methods:

[0044] Embodiment 1:

[0045] As attached Figures 1 to 4 As shown: a dynamic ultrasonic measuring device for fetal growth monitoring includes an ultrasonic probe body 1, and a transmission line 11 is connected to one side of the ultrasonic probe body 1. A gripping handle 2 is provided on the outer cover of the ultrasonic probe body 1, and a slot 21 is provided on the gripping handle 2. The slot 21 is located between adjacent adjustment rods 3, and the ultrasonic probe body 1 is located in the slot 21, and the ultrasonic probe body 1 and the slot 21 are clearance-matched; a driving mechanism for pushing the ultrasonic probe body 1 to move is provided in the gripping handle 2. In this embodiment, a deformable rubber block (not shown in the figure) is welded around the slot 21, and the ultrasonic probe is clamped with the gripping handle 2 through the rubber block to prevent the ultrasonic probe body 1 from falling out of the slot 21, thereby improving stability during use.

[0046] The driving mechanism includes a plurality of driving members (the driving members are electric push rods 6) and an adsorption plate 12 for adhering the ultrasonic probe body 1, the adsorption plate 12 is slidably matched with the holding handle 2, and the ultrasonic probe body 1 rotates around the adsorption plate 12; the driving members are symmetrically arranged around the card slot 21, the driving members are welded to the holding handle 2, the output end of the driving members is slidably matched with the holding handle 2, and the output end of the driving members is welded with an inclined contact block 61, and the contact block 61 is located in the card slot 21.

[0047] A plurality of mounting grooves 22 are formed around the gripping handle 2, and an adjusting rod 3 is provided in each mounting groove 22. A roller 4 is hingedly connected to the end of the adjusting rod 3 away from the gripping handle 2. A second pressure sensor is also provided between the spring 32 and the support rod 31. An isolation layer (not shown in the figure) for isolating ultrasonic radiation is provided at the bottom of the gripping portion and in the card slot 21. In this embodiment, the isolation layer is made of aluminum.

[0048] It also includes a processing center (not shown in the figure), which includes but is not limited to a computer. A plurality of first pressure sensors 13 are fixedly connected to the top of the gripping handle 2. The first pressure sensors 13 are used to measure the real-time pressure value when the gripping handle 2 is in contact with the body surface of the pregnant woman, and send the real-time pressure value to the processing center; the second pressure sensor is used to measure the feedback force when the support rod 31 is in contact with the body surface of the pregnant woman, and send the feedback force to the processing center.

[0049] The processing center is used to mark the feedback force based on the position of adjacent support rods 31 to form different reference data sets for storage; calculate the difference based on the feedback force in the reference data set, and then compare the difference with the set displacement value; if the difference is greater than the displacement value, the position of the support rod 31 with a large feedback force in the reference data set is obtained and marked as the lifting direction, and then a rotation instruction is sent to the driving mechanism based on the lifting direction, and the driving mechanism controls the rotation direction of the ultrasound probe body 1 based on the rotation instruction; if the difference is less than the displacement value, the processing center compares the real-time pressure value with the set standard value, and if the real-time pressure value is greater than the standard value, a maintenance instruction is sent to the driving mechanism; if the real-time pressure value is less than the standard value, a pressure instruction is sent to the driving mechanism.

[0050] The specific implementation process is as follows: first, the ultrasound probe body 1 is snapped into the slot 21 so that the detection end of the ultrasound probe body 1 extends out of the gripping handle 2. The doctor holds the gripping handle 2 in contact with the pregnant woman's body surface so that the bottom of the gripping handle 2 maintains vertical contact with the pregnant woman's body surface.

[0051] During the fetal ultrasound detection process, the roller 4 on the adjustment rod 3 slides on the pregnant woman's body surface, and the adjustment rod 3 forms four-corner supports to support the gripping handle 2, so as to ensure that the ultrasound probe body 1 is in a vertical state with the pregnant woman's body surface during use, and to provide a guarantee for the stability of subsequent ultrasound image acquisition. When the roller 4 in different directions contacts the pregnant woman's body surface, the feedback force on the support rod 31 indicates that the lifting direction has been confirmed to control the rotation angle of the ultrasound probe body 1, so as to ensure that the ultrasound probe body 1 is in a vertical state with the pregnant woman's body surface, provide a basic angle guarantee, and facilitate the subsequent rotation and adjustment of the ultrasound probe body 1 to point to the umbilical cord, which helps to display the umbilical blood flow waveform more clearly and improve the reliability of the monitoring results.

[0052] At the same time, the driving member drives the contact block 61 to push the ultrasound probe body 1 in the card slot 21, so as to realize the pressure detection between the ultrasound probe body 1 and the pregnant woman's body surface, and at the same time, the adsorption plate 12 provides a rotation point for the ultrasound probe body 1, and then the different extension lengths of the driving member are used to drive the ultrasound probe body 1 to rotate around the adsorption plate 12, so as to realize the adjustment of the detection angle between the umbilical cord and the ultrasound probe body 1. The use of the driving mechanism instead of manual pressure or control reduces the fetal ultrasound experience required by medical personnel, and only the gripping handle 2 and the ultrasound probe body 1 need to be driven to move, which reduces the difficulty of operation.

[0053] Embodiment 2:

[0054] The difference from Example 1 is that the processing center is also used to compare the difference corresponding to the feedback force in the data set, and the processing center uses the basic angle corresponding to the displacement value as a reference; when the difference is greater than the displacement value, the adjustment value between the difference and the displacement value is calculated, and the processing center converts the adjustment value into an adjustment angle, and generates a rotation command to the drive mechanism based on the adjustment angle.

[0055] For example, when the ultrasound probe body 1 is in contact with the pregnant woman's body surface, due to the deformation space provided by the spring 32, when the height difference between the adjacent support rods 31 occurs, a difference is formed, which indicates the curvature of the pregnant woman's body surface. The basic angle corresponding to the displacement value is used as a reference to provide a reference for the subsequent adjustment angle generation, thereby providing basic parameters for the control drive mechanism, improving the accuracy of the ultrasound probe body 1 during rotation, so that when a clear ultrasound image of a certain position is observed, the ultrasound probe body 1 is controlled to rotate according to the set optimal angle, so as to find a better monitoring position, which helps to display the umbilical blood flow waveform more clearly.

[0056] Embodiment 3:

[0057] The difference from Example 2 is that a plurality of heating cavities 51 are opened on both sides of the card slot 21, and the heating cavities 51 are arranged in a ring shape with the gripping handle 2 as the center. A plurality of heat-conducting layers 5 are provided on one side of the card slot 21 close to the ultrasonic probe body 1. In this embodiment, the heat-conducting layer 5 is copper, and the heat-conducting layer 5 is connected to the heating cavity 51.

[0058] The specific implementation process is as follows: Since the ultrasonic probe needs to continuously transmit and receive ultrasonic signals during use, the heat generated during the operation of the ultrasonic probe body 1 is guided by the heat conductive layer 5 to reduce the impact of local heat accumulation on the doctor's grip, so as to heat the grip handle 2, which is convenient for doctors to use in winter and improves the comfort of doctors during use.

[0059] Embodiment 4:

[0060] The difference from Example 3 is that a plurality of hidden cavities (not shown in the figure) are opened on the gripping handle 2, and a shielding plate 23 which is rotatably matched with the gripping handle 2 is provided in each of the hidden cavities, and the hidden cavities and the adjusting rod 3 are on the same horizontal line; the adjusting rod 3 is rotatably matched with the gripping handle 2, and the top of the support rod 31 is threadedly connected with the adjusting rod 3.

[0061] The specific implementation process is as follows: after the device is used, since the extension of the adjusting rod 3 temporarily occupies more space, the hidden cavity is set to provide space for the placement of the adjusting rod 3, so that the adjusting rod 3 can be stored inside when the device is not in use, so as to reduce the space occupied and facilitate the storage of the gripping handle 2.

[0062] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention.
