Description

Technical Field

[0001] This invention belongs to the field of medical device technology, specifically relating to a detection device and detection method. Background Technology

[0002] Subcutaneous edema refers to the pathological sign caused by the abnormal accumulation of body fluid in the interstitial spaces of soft tissues. It is not an independent disease itself, but rather an external manifestation of a certain pathological condition or physiological disorder in the body. Its severity can directly reflect the progression of the corresponding disease. Furthermore, subcutaneous edema can hinder the normal uptake and metabolism of oxygen and nutrients by tissue cells, leading to tissue cell damage and negatively impacting the recovery and prognosis of severely ill patients.

[0003] Currently, the most commonly used method for clinical assessment of subcutaneous edema is the pitting test. This method involves medical staff manually pressing the skin of the patient's test site to create a pit, and then manually recording the time it takes for the pit to recover. However, this method has obvious limitations. On the one hand, the key operations such as the pressure and time of pressure cannot be standardized for each patient in each assessment. On the other hand, it cannot obtain data on the rate of pit recovery to allow medical staff to assess the degree of edema in patients. Summary of the Invention

In the axial direction of the pressing seat, the first limiting protrusion is located on the side of the second limiting protrusion closer to the telescopic device.

[0009] In some embodiments, the pressing assembly further includes a limiting cylinder, one end of which is connected to one end of the pressing seat, and the other end of which is sleeved on the outer periphery of the fixed seat, and the limiting cylinder can slide relative to the fixed seat.

[0011] The present invention also provides a detection method based on the detection device described in the above embodiments.

[0012] The detection method of this invention includes the following steps: S100: Obtain the distance between the compression head and the skin of the patient's test site, and set it as the initial distance D1; S200: Press the skin of the patient's test site to form a depression on the skin of the patient's test site, and obtain the distance between the pressing head and the depression, which is set as the initial pressing distance D2; S300: Collect the distance between the pressing head and the indentation according to the preset time period T, and set it as the indentation recovery distance D31. Calculate the indentation recovery speed V based on the indentation recovery distance D31, the preset time period T and the initial pressing distance D2. S400: Determine whether the difference between the dent recovery distance D2 and the initial distance D1 exceeds the first preset range G1. If yes, repeat step S300; if no, the detection is complete, and output the recovery speed V of all dents.

[0013] In some embodiments, step S100 further includes the following steps: S110: Control the first electromagnet and the second electromagnet to attract each other, detect the sliding seat to drive the probe to extend out of the pressing head through the probe through hole, and obtain the distance between the sliding seat and the first end plate when the sliding seat is in the second position, set as the first distance L1, and obtain the length of the probe extending out of the pressing head when the sliding seat is in the second position, set as the first extension length Q1. S120: Control the first electromagnet and the second electromagnet to stop attracting each other, control the telescopic device to extend and drive the pressing component to move toward the skin of the patient's test site, and collect the distance between the first end plate and the detection sliding seat in real time, which is set as the second distance L2. When the difference between the first distance and the second distance exceeds the second preset range G2, control the telescopic device to stop extending, and obtain the extension amount of the telescopic device, which is set as the first extension amount A1, and obtain the difference between the first distance L1 and the second distance L2, which is set as the first difference B1. S130: Obtain the probe extension. Based on the first extension A1, the first difference B, and the first extension length Q1, the initial distance D1 is obtained. The initial distance D1 = A1 - B1 + Q1.

[0014] In some embodiments, step S200 further includes the following steps: controlling the extension of the telescopic device to move the pressing component toward the skin of the patient's test site, thereby moving the pressing component toward the skin of the patient's test site, so that the pressing head forms a depression on the skin of the patient's test site, and obtaining the extension amount of the telescopic device, which is set as the initial pressing distance C.

S330: The dent recovery distance D31 is obtained based on the second elongation A2, the second difference B2, and the second elongation Q2 degrees; the dent recovery distance D31 = A2 - B2 + Q2.

[0016] In some embodiments, step S300, determining the dent recovery speed V based on the dent recovery distance D31, the preset time period T, and the initial pressing distance D2 includes the following steps: dent recovery speed V = (D2-D31) / T.

[0017] In some embodiments, step S400: determine whether the difference between the depression recovery distance D2 and the initial distance D1 exceeds the first preset range G1; if so, repeat step S300. During the repeated step S300, the distance between the pressing head and the indentation is collected for the nth time according to the preset time period T, and is set as the indentation recovery distance D3n. The indentation recovery speed V = (D3n - D3(n-1)) / T, where n ≥ 2 and n is an integer. Attached Figure Description

[0020] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0021] In order to address the lack of effective equipment for quantifying the recovery speed of indentations in related technologies, this invention provides a detection device.

[0022] The detection device of this invention includes a fixing component 1, a detection component 2, a control module 8, and a timing module 9.

[0023] The fixture 1 is fixed to the clinical facility, and the detection component 2 is mounted on the fixture 1. The detection component 2 is used to press on the patient's skin area to be tested.

[0024] It is understood that when the detection component 2 presses on the patient's test site, the relative position of the patient's test site and the fixing component 1 should be fixed. That is, when the detection component 2 presses on the patient's test site, the patient's test site should remain still. For example, when pressing on the lower leg of the patient's lower limb, the lower leg of the patient's lower limb should remain still during the pressing process. Only in this way can the accuracy of the detection device of the present invention be guaranteed.

[0025] At the same time, such as Figures 1-3 As shown, the detection component 2 includes a fixed base 201 and a pressing component 202. The fixed base 201 is mounted on the fixing member 1. A telescopic device 3 is provided inside the fixed base 201. The telescopic end 301 of the telescopic device 3 extends out of the fixed base 201 and extends to the outside of the fixed base 201. For example, the telescopic device 3 can be a telescopic motor. The telescopic motor usually has a body and a telescopic rod. The body of the telescopic motor can be set inside the fixed base 201. The telescopic rod of the telescopic motor can extend out of the fixed base 201 and connect with other components, such as the pressing base 2021. The position where the telescopic rod is connected to the pressing base 2021 can be understood as the telescopic end 301 of the telescopic device 3.

[0026] like Figure 2As shown, the pressing assembly 202 includes a pressing seat 2021 and a pressing head 2022. One end of the pressing seat 2021 is connected to the telescopic end 301, and part of the pressing head 2022 is sleeved on the other end of the pressing seat 2021. A pressure sensor 10 is provided between the pressing head 2022 and the pressing seat 2021.

[0027] It is understandable that part of the pressing head 2022 is sleeved on the other end of the pressing base 2021, so that the pressing head 2022 can slide relative to the pressing base 2021, so that when the pressing head 2022 is subjected to pressure, it can transfer the force it receives to the pressure sensor 10 through sliding, so that the pressure sensor 10 can collect the pressure.

[0028] By setting the pressure sensor 10, the pressure applied by the pressure head 2022 to the patient's test site can be detected in real time, so as to apply a preset pressure value to the patient.

[0029] It is also understandable that the sliding range of the pressing head 2022 relative to the pressing base 2021 is negligible. The main purpose is to prove that the pressing head 2022 and the pressing base 2021 are movably connected, so that the pressing head 2022 can transmit the force it receives to the pressure sensor 10. In other words, when setting the sliding range between the pressing head 2022 and the pressing base 2021, it is necessary to avoid excessive displacement from affecting the accuracy of subsequent detection of the indentation recovery speed.

[0030] like Figures 1-3 As shown, the pressing seat 2021 has a pressing mounting cavity 20211, and a detection component 4 is provided in the pressing mounting cavity 20211. The detection component 4 includes a detection rod group 401, and the detection rod group 401 includes a detection sliding seat. The detection sliding seat is disposed in the pressing mounting cavity 20211, and the detection sliding seat 4011 can slide in the axial direction of the pressing mounting cavity 20211. The pressing base 2021 includes a pressing cylinder 20212 and a first end plate 20213 and a second end plate 20214 disposed opposite to each other in the axial direction. The pressing cylinder 20212, the first end plate 20213 and the second end plate 20214 define a pressing mounting cavity 20211, and the first end plate 20213 is connected to the telescopic end 301. The probe rod assembly 401 also includes a probe 4012. One end of the probe 4012 is connected to the detection sliding seat 4011, and the other end of the probe 4012 extends through the second end plate 20214 to the outside of the pressing fixing seat 201. The pressing head 2022 is provided with a probe through hole 20221 for the probe 4012 to pass through. The detection slide block 4011 can move between a first position and a second position. In the first position, the detection slide block 4011 abuts against the first end plate 20213; in the second position, the detection slide block 4011 abuts against the second end plate 20214. A first electromagnet 5 is provided on the side of the detection slide block 4011 facing the second end plate 20214, and a second electromagnet 6 is provided on the side of the second end plate 20214 facing the detection slide block 4011 corresponding to the first electromagnet 5. The first end plate 20213 is provided with a distance sensor 7 on the side facing the detection sliding seat 4011. The distance sensor 7 is used to collect the distance between the first end plate 20213 and the detection sliding seat 4011. It is understandable that the detection slide block 4011 can be moved by controlling the magnetism of the first electromagnet 5 and the second electromagnet 6. For example, when the detection slide block 4011 needs to be in the first position, the magnetism of the first electromagnet 5 and the second electromagnet 6 is controlled to be opposite, and the first electromagnet 5 and the second electromagnet 6 attract each other, moving the detection slide block 4011 to the first position, so that the detection slide block 4011 abuts against the second end plate 20214; when the detection slide block 4011 needs to be in the second position, the magnetism of the first electromagnet 5 and the second electromagnet 6 is controlled to be the same, and the first electromagnet 5 and the second electromagnet 6 repel each other, moving the detection slide block 4011 to the second position, so that the detection slide block 4011 abuts against the first end plate 20213.

[0031] To facilitate control of the relevant components in the detection device of this embodiment of the invention, the detection device of this embodiment of the invention further includes a control module 8 and a timing module 9, wherein the control module 8 is signal-connected to the telescopic device 3, the pressure sensor 10, the first electromagnet 5, the second electromagnet 6, and the distance sensor 7; the timing module 9 is signal-connected to the control module 8.

[0032] By setting the timing module 9 and the control module 8 to be connected by signal, the detection process of the detection device of this embodiment can be timed. On the one hand, it is convenient to control the pressing head 2022 to press the patient's test site for a preset time; on the other hand, it can provide time data for subsequent calculation of the indentation recovery speed.

[0033] It is understood that the control module 8 is signal-connected to the telescopic device 3, and the control module 8 can control the telescopic device 3 to extend and retract; at the same time, the timing module 9 is signal-connected to the control module 8, and the control module 8 can control the extension and retraction time of the telescopic device 3 through the timing module 9; at the same time, the pressure sensor 10 is signal-connected to the control module 8, and the control module 8 can control the extension and retraction of the telescopic device 3 through the pressure sensor 10; so that the telescopic device 3 can drive the pressing component 202 to apply a preset pressure to the patient's test site; at the same time, the first electromagnet 5 and the second electromagnet 6 are both signal-connected to the control module 8, and the control module 8 can control the magnetism between the first electromagnet 5 and the second electromagnet 6 to drive the detection sliding seat 4011 to move between the first position and the second position.

[0034] The detection device of this invention can automatically press on the patient's test site to form an indentation and detect the recovery speed of the indentation. This allows for the quantification of the indentation recovery speed, facilitating medical staff's assessment of the edema level of the patient's test site based on the indentation speed. This eliminates the need for manual pressing, significantly reducing the workload of medical staff. Patients can also use the detection device to detect the indentation recovery speed of their test site, further reducing the workload of medical staff. Furthermore, the detection device can press on the patient's test site to form an indentation according to a preset time and pressure. This allows for the detection of the indentation recovery speed according to a unified standard. In other words, during treatment, patients can use the detection device to press on the same area with the same time and pressure to form an indentation and detect the indentation recovery speed, thereby evaluating the treatment effect based on the indentation recovery speed.

[0035] Therefore, the detection device of this invention can perform the same pressure and pressure time for each patient in each detection process to ensure the accuracy of the detection results; the detection device of this invention can also obtain data on the recovery speed of the indentation at the test site for medical staff to assess the degree of edema in patients.

[0036] In some embodiments, the pressing head 2022 includes a pressing part 20222 and a sleeve part 20223 connected together. The pressing part 20222 is hemispherical. It is understood that by setting the pressing part 20222 to a hemispherical shape, it is convenient for the pressing part 20222 to press the skin of the patient's test site to form a depression. At the same time, the depression formed is also convenient for subsequent measurement of the depth of the depression.

[0037] Meanwhile, the sleeve part 20223 is sleeved on the other end of the pressing seat 2021, and the pressure sensor 10 is disposed on the second end plate 20214; the inner wall of the sleeve part 20223 is provided with a first limiting protrusion ring 11, and the outer periphery of the pressing seat 2021 is provided with a second limiting protrusion ring 12. In the axial direction of the pressing seat 2021, the first limiting protrusion ring 11 is located on the side of the second limiting flange close to the telescopic device 3.

[0038] Therefore, when the telescopic device 3 drives the pressing assembly 202 to press the patient's test site, the pressing head 2022 can transmit the pressure it receives to the pressure sensor 10, so that the pressure sensor 10 can collect the pressure received by the pressing head 2022. Since the action of forces is mutual, the pressure sensor 10 can collect the force applied by the pressing head 2022 to the patient's test site.

[0039] In some embodiments, the pressing assembly 202 further includes a limiting cylinder 13, one end of which is connected to one end of the pressing seat 2021, and the other end of which is sleeved on the outer periphery of the fixed seat 201. The limiting cylinder 13 can slide relative to the fixed seat 201.

[0040] By setting the limiting cylinder 13, the problem of the pressing seat 2021 shifting when the telescopic device 3 moves the pressing seat 2021 can be avoided.

[0041] In some embodiments, the outer periphery of the fixing base 201 is provided with a limiting protrusion 14, which extends radially along the fixing base 201. The inner wall of the limiting cylinder 13 is provided with a limiting groove 15, which extends radially along the fixing base 201. The limiting protrusion 14 is fitted into the limiting groove 15. There are multiple limiting protrusions 14, which are spaced apart circumferentially on the fixing base 201. There are also multiple limiting grooves 15, which are spaced apart circumferentially on the limiting cylinder 13. The multiple limiting protrusions 14 are fitted into the limiting grooves 15 one-to-one.

[0042] By setting the limiting protrusion 14 and the limiting groove 15, the problem of the pressing seat 2021 shifting when the telescopic device 3 drives the pressing seat 2021 to move can be further avoided.

[0043] The present invention also provides a detection method based on the detection device described in the above embodiments.

[0044] The detection method of this invention includes the following steps: S100: Obtain the distance between the compression head 2022 and the skin of the patient's test site, and set it as the initial distance D1; S200: Press the skin of the patient's test site to form a depression on the skin of the patient's test site, and obtain the distance between the pressing head 2022 and the depression, and set it as the initial pressing distance D2; S300: Collect the distance between the pressing head 2022 and the indentation according to the preset time period T, and set it as the indentation recovery distance D31. Calculate the indentation recovery speed V based on the indentation recovery distance D31, the preset time period T and the initial pressing distance D2. S400: Determine whether the difference between the dent recovery distance D2 and the initial distance D1 exceeds the first preset range G1. If yes, repeat step S300; if no, the detection is complete, and output the recovery speed V of all dents.

[0045] It is understood that the detection method of this invention can press the skin of the patient's test site to form an indentation, and at the same time collect the distance between the indentation and the pressing head 2022 according to a preset cycle to obtain the indentation recovery speed V, which can quantify the indentation recovery speed of the patient's test site.

[0046] It is understandable that when the difference between the depression recovery distance D2 and the initial distance D1 is 0, it means that the depression of the patient's test site has been fully recovered, and the first preset range G1 can be set according to actual needs. In other words, the test can be ended without waiting for the depression of the patient's test site to be fully recovered.

[0047] Medical staff can assess the indentation recovery speed of the patient's test site based on the output indentation recovery speed V. Compared with the existing method of manually pressing the patient's test site and recording the indentation recovery time, the detection method of this invention can automatically press the patient's test site to form an indentation and detect the indentation recovery speed V, allowing medical staff to assess the edema level of the patient's test site, greatly reducing the workload of medical staff. At the same time, the detection method of this invention can press the patient's test site according to a preset pressing pressure and preset pressing time. That is to say, the pressing pressure and pressing time of the patient's test site can be adjusted by medical staff according to different patients. At the same time, it can also ensure that the same pressing pressure and pressing time are used for the same patient, so as to more accurately assess the treatment effect of edema in the patient's test site during the patient's treatment.

[0048] In some embodiments, step S100 further includes the following steps: S110: Control the first electromagnet 5 and the second electromagnet 6 to attract each other, detect the sliding seat 4011 to drive the probe 4012 to extend out of the pressing head 2022 through the probe through hole 20221, and obtain the distance between the sliding seat 4011 and the first end plate 20213 when the sliding seat 4011 is in the second position, set as the first distance L1, and obtain the length of the probe 4012 extending out of the pressing head 2022 when the sliding seat 4011 is in the second position, set as the first extension length Q1; S120: Control the first electromagnet 5 and the second electromagnet 6 to stop attracting each other, control the telescopic device 3 to extend and drive the pressing component 202 to move toward the skin of the patient's test site, and collect the distance between the first end plate 20213 and the detection sliding seat 4011 in real time, set as the second distance L2. When the difference between the first distance and the second distance exceeds the second preset range G2, control the telescopic device 3 to stop extending, and obtain the extension amount of the telescopic device 3, set as the first extension amount A1, and obtain the difference between the first distance L1 and the second distance L2, set as the first difference B1. S130: Obtain the initial distance D1 of probe 4012 extension based on the first elongation A1, the first difference B and the first extension length Q1.

[0049] Furthermore, the initial distance D1 = A1 - B1 + Q1.

[0050] It is understood that step S100 is the first step of the detection method of this embodiment of the invention, the purpose of which is to determine the distance between the skin of the patient's test site and the pressing head 2022, and set it as the initial distance D1.

[0051] Then in step S110, as Figure 4 As shown, the control module 8 controls the first electromagnet 5 and the second electromagnet 6 to have different magnetic properties, so that the first electromagnet 5 and the second electromagnet 6 can attract each other. Since the initial state of the detection slide 4011 is in the first position, the mutual attraction between the first electromagnet 5 and the second electromagnet 6 can make the detection slide 4011 move towards the second end plate 20214, thereby driving the spring needle to extend out of the pressing head 2022 through the spring needle through the spring needle through hole, and finally making the detection slide 4011 in the second position. Then, the distance sensor 7 collects the distance between the detection slide 4011 and the first end plate 20213 as the first distance L1, and obtains the length of the spring needle extending out of the pressing head 2022, which is set as the first extension length Q1.

[0052] It is understandable that, since the specifications of the pressing base 2021 and the spring pin are fixed, in order to save detection time, the first distance L1 and the first extension length Q1 can be directly preset in the control module 8 and can be directly called for calculation in the subsequent calculation process.

[0053] Subsequently, in step S120, the first electromagnet 5 and the second electromagnet 6 are first controlled to stop attracting each other. This can be understood as the control module 8 controlling the first electromagnet 5 and the second electromagnet 6 to be de-energized, so that the probe 4012 and the detection sliding seat 4011 can move in subsequent steps. Then, the control module 8 controls the telescopic device 3 to extend, driving the pressing component 202 to move towards the skin of the patient's test site. Figure 5 As shown, since the probe 4012 has extended beyond the pressure head 2022, the probe 4012 will first contact the skin of the patient's test site. After the probe 4012 contacts the skin of the patient's test site, as... Figure 6 As shown, when the telescopic device 3 continues to extend, the probe 4012 will drive the detection slide 4011 to move toward the first end plate 20213. At the same time, the distance sensor 7 detects the distance between the detection slide 4011 and the first end plate 20213 in real time. When the detection slide 4011 moves toward the first end plate 20213 beyond the second preset range G2, that is, when the difference between the first distance L1 and the second distance L2 exceeds the second preset range G2, the control module 8 controls the telescopic device 3 to stop extending. At this time, the extension amount of the telescopic device 3 is obtained and set as the first extension amount A1, and the difference between the first distance L1 and the second distance L2 is obtained and set as the first difference B1. It can be understood that the first difference B1 here is the distance that the detection slide 4011 moves toward the first end plate.

[0054] In subsequent step 130, the control module 8 obtains the probe 4012 extending and calculates the initial distance D1 based on the first extension A1, the first difference B and the first extension length Q. Specifically, the initial distance D1 = A1 - B1 + Q1.

[0055] Subsequently, the control module 8 controls the telescopic device 3 to shorten to the initial state. At the same time, the control module 8 controls the first electromagnet 5 and the second electromagnet 6 to have the same magnetism, so that the first electromagnet 5 and the second electromagnet 6 repel each other, causing the detection sliding seat 4011 to move towards the first end plate 20213 and move to the first position, while driving the probe 4012 to retract to the initial state.

[0056] In some embodiments, step S200 further includes the following steps: controlling the telescopic device 3 to extend and drive the pressing component 202 to move toward the skin of the patient's test site, thereby driving the pressing component 202 to move toward the skin of the patient's test site, so that the pressing head 2022 forms a depression on the skin of the patient's test site, and obtaining the extension amount of the telescopic device 3, which is set as the initial pressing distance C.

[0057] It is understood that step S200 is the second step of the detection method in this embodiment of the invention. Its purpose is to determine the distance between the indentation of the patient's test site and the pressing head 2022, which is set as the initial pressing distance D2. The difference between the initial pressing distance D2 and the initial distance D1 can be understood as the depth of the indentation.

[0058] In step S200, as Figures 7-9 As shown, the control module 8 controls the extension device 3 to extend, causing the pressing component 202 to move toward the skin of the patient's test site. When the pressing head 2022 comes into contact with the patient's test skin, the skin of the patient's test site will generate pressure from the pressing head 2022. The pressing head 2022 can transmit this pressure to the pressure sensor 10. That is, the pressure sensor 10 can detect the magnitude of the pressure applied by the pressing head 2022 of the pressing component 202 to the skin of the patient's test site. When the pressure sensor 10 detects that the pressure applied by the pressing head 2022 to the skin of the patient's test site is equal to the preset value, the control module 8 controls the extension device 3 to stop extending, the timing module 9 starts timing, and after maintaining the pressing of the skin of the test site for the preset time, the control module 8 controls the extension device 3 to shorten to the initial state.

[0059] In some embodiments, step S300, collecting the distance between the pressing head 2022 and the dent according to a preset time period T and setting it as the dent recovery distance D31, includes the following steps: S310: Control the first electromagnet 5 and the second electromagnet 6 to attract each other, detect the sliding seat 4011 to drive the probe 4012 to extend out of the pressing head 2022 through the probe through hole 20221, and obtain the distance between the sliding seat 4011 and the first end plate 20213 when the sliding seat 4011 is in the second position, set as the third distance L3, and obtain the length of the probe 4012 extending out of the pressing head 2022 when the sliding seat 4011 is in the second position, set as the second extension length Q2; S320: Control the first electromagnet 5 and the second electromagnet 6 to stop attracting each other, control the telescopic device 3 to extend and drive the pressing component 202 to move toward the skin of the patient's test site, and collect the distance between the first end plate 20213 and the detection sliding seat 4011 in real time, set as the fourth distance L4. When the difference between the third distance L3 and the fourth distance L4 exceeds the third preset range G3, control the telescopic device 3 to stop extending, and obtain the extension amount of the telescopic device 3, set as the second extension amount A2, and obtain the difference between the third distance L3 and the fourth distance L4, set as the second difference B2. S330: The indentation recovery distance D31 is obtained based on the second elongation A2, the second difference B2, and the second extension length Q2.

[0060] Furthermore, the depression recovery distance D31 = A2 - B2 + Q2.

[0061] It is understood that step S300 is the third step of the detection method in this embodiment of the invention, and its purpose is to determine the indentation recovery rate V.

[0062] Then in step S310, as Figure 10 As shown, the control module 8 controls the first electromagnet 5 and the second electromagnet 6 to have opposite magnetic properties, so that the first electromagnet 5 and the second electromagnet 6 can attract each other. Since the initial state of the detection slide 4011 is in the first position, the mutual attraction between the first electromagnet 5 and the second electromagnet 6 can make the detection slide 4011 move towards the second end plate 20214, thereby driving the spring needle to extend out of the pressing head 2022 through the spring needle through the spring needle through hole, and finally making the detection slide 4011 in the second position. Then, the distance sensor 7 collects the distance between the detection slide 4011 and the first end plate 20213 as the third distance L3, and obtains the length of the spring needle extending out of the pressing head 2022, which is set as the second extension length Q2.

[0063] It is understandable that, since the specifications of the pressing base 2021 and the spring pin are fixed, in order to save detection time, the third distance L3 and the second extension length Q2 can be directly preset in the control module 8 and can be directly called for calculation in the subsequent calculation process. Similarly, it is understandable that the third distance L3 is equal to the first distance L1, and the second extension length Q2 is equal to the first extension length Q1.

[0064] Subsequently, in step S320, the first electromagnet 5 and the second electromagnet 6 are first controlled to stop attracting each other. This can be understood as the control module 8 controlling the first electromagnet 5 and the second electromagnet 6 to be de-energized, so that the probe 4012 and the detection sliding seat 4011 can move in subsequent steps. Then, the control module 8 controls the telescopic device 3 to extend, driving the pressing component 202 to move towards the skin of the patient's test site. Figure 11 As shown, since the probe 4012 has extended outside the pressing head 2022, the probe 4012 will first come into contact with the skin of the patient's test site. After the probe 4012 comes into contact with the skin of the patient's test site, the telescopic device 3 continues to extend. The probe 4012 will drive the detection sliding seat 4011 to move toward the first end plate 20213. At the same time, the distance sensor 7 detects the distance between the detection sliding seat 4011 and the first end plate 20213 in real time. When the detection sliding seat 4011 moves toward the first end plate 20213 beyond the third preset range G3, that is, when the difference between the first distance and the second distance exceeds the third preset range G3, the control module 8 controls the telescopic device 3 to stop extending. At this time, the extension amount of the telescopic device 3 is obtained and set as the second extension amount A2, and the difference between the third distance L3 and the third distance L4 is obtained and set as the second difference B2. In subsequent step S330, the control module 8 obtains the probe 4012 extension and calculates the dent recovery distance D31 based on the second extension A2, the second difference B2 and the first extension length Q2. The specific dent recovery distance D31 = A2 - B2 + Q2.

[0065] Subsequently, the control module 8 controls the telescopic device 3 to shorten to the initial state. At the same time, the control module 8 controls the first electromagnet 5 and the second electromagnet 6 to have the same magnetism, so that the first electromagnet 5 and the second electromagnet 6 repel each other, causing the detection sliding seat 4011 to move towards the first end plate 20213 and move to the first position, while driving the probe 4012 to retract to the initial state.

[0066] In some embodiments, step S300, determining the dent recovery speed V based on the dent recovery distance D31, the preset time period T, and the initial pressing distance D2 includes the following steps: dent recovery speed V = (D2-D31) / T. Here, the preset time period T can be understood as follows: after the pressing head forms a dent on the test area, the dent on the test area is detected at preset time intervals T, and the distance between the dent and the pressing head is detected to calculate the dent recovery speed.

[0067] It is understandable that the depression recovery speed V obtained from the first execution of step S300 can be set as the first depression recovery speed V1, so as to facilitate the subsequent statistical analysis of all data of the depression recovery speed V detected in this test.

[0068] In some embodiments, in step S400: it is determined whether the difference between the depression recovery distance D2 and the initial distance D1 exceeds the first preset range G1; if so, step S300 is repeated. One data processing method is to collect the distance between the pressing head 2022 and the indentation for the nth time during the repeated step S300, according to the preset time period T, and set it as the indentation recovery distance D3n, and the indentation recovery speed Vn=(D3n-D3(n-1)) / T, where (n≥2, and n is an integer).

[0069] In other words, the distance between the second sampling pressing head 2022 and the indentation is set as the indentation distance D32, and the indentation recovery speed V2=(D32-D31) / T, where n≥2 and n is an integer.

[0070] Similarly, the distance between the pressure head 2022 and the indentation in the third sampling is set as the indentation distance D32, and the indentation recovery speed V3 = (D33 - D32) / T, where n ≥ 2 and n is an integer.

[0071] Another data processing method is to collect the distance between the pressing head 2022 and the dent for the nth time during the repeated step S300 according to the preset time period T, and set it as the dent recovery distance D3n, and the dent recovery speed Vn=(D3n-D3) / nT, where n≥2 and n is an integer.

[0072] In other words, the distance between the second sampling pressing head 2022 and the indentation is set as the indentation distance D32, and the indentation recovery speed V2=(D32-D3) / 2T, where n≥2 and n is an integer.

[0073] Similarly, the distance between the pressure head 2022 and the indentation in the third sampling is set as the indentation distance D32, and the indentation recovery speed V3 = (D33 - D3) / 3T, where n ≥ 2 and n is an integer.

[0074] Both of the above data processing methods can obtain data on the recovery speed of the indentation at the patient's test site, which can be used by medical staff to assess the degree of edema at the test site. The specific data processing method used can be selected according to actual needs.

[0075] It is also understood that both of the above data processing methods can calculate the recovery speed of the depression. Therefore, the detection method of this invention can comprehensively assess the degree of edema in the patient's test area by calculating the recovery speed of the depression.
