Description

Technical Field

[0001] The present invention relates to the field of medical devices, and more specifically, to a multifunctional neurology examination device. Background Art

[0002] Neurology examination devices are medical equipment used to evaluate and diagnose neurological diseases. These devices can help doctors determine whether a patient has neurological problems, as well as the nature and severity of the problems. The main devices include electroencephalogram devices, electromyogram and nerve conduction velocity test devices, magnetic resonance imaging and computed tomography devices, etc. There are also some tools applicable to neurology examinations, such as percussion hammers.

[0003] The percussion hammer is one of the examination tools in neurology. In neurology, doctors often use the percussion hammer for a series of examinations, such as tendon reflex examinations, to evaluate the patient's neurological function. By gently tapping the patient's tendon, doctors can observe the muscle contraction response to determine whether the nerve conduction is normal. However, when using the percussion hammer, doctors need to control the force to avoid causing discomfort to the patient.

[0004] In the prior art, when using the percussion hammer, doctors will adjust different forces according to the patient's condition, and the patient's own body fatness will also affect the force when tapping the percussion hammer. Experienced doctors can control the force, but inexperienced doctors are extremely likely to affect the examination results due to too large or too small tapping force. Summary of the Invention

[0005] Aiming at the problems existing in the prior art, the purpose of the present invention is to provide a multifunctional neurology examination device.

[0006] To solve the above problems, the present invention adopts the following technical solutions, which can achieve controlling the impact force of the percussion block through the thickness of the patient's own skin and subcutaneous tissue, effectively avoiding the influence on the examination results caused by too large or too small percussion force.

[0007] A multifunctional neurology examination device includes a hammer body. An activity groove is vertically opened downward inside the hammer body.

[0016] Among them, d is the distance that ultrasonic waves pass through the patient's skin and subcutaneous tissue, V is the ultrasonic wave propagation speed, Δt is the time interval from the emission of ultrasonic waves to being reflected back and captured by the receiver, K is a preset coefficient, d is proportional to the product of V and Δt, that is, the longer the interval time, the longer the distance of the patient's skin and subcutaneous tissue. Because the ultrasonic wave propagation speed varies in different patients and different skin media, d here is an approximate calculated value. The value of coefficient K is determined by a large number of previous experiments, so that the thickness d is as close as possible to the actual value of the distance of the patient's skin and subcutaneous tissue. When the thickness of the skin tissue to be detected is between 700 and 2500 microns, the adsorption force intensity on the percussion block is adjusted within the range of 0.1 - 0.5 Mpa, and the adsorption force error is controlled within ±5%;

[0017] Further, a material injection component is provided inside the hammer body, and the material injection component includes a limiting groove opened inside the hammer body.

[0018] Further, a connecting frame is slidably connected inside the limiting groove, the chassis is fixedly connected to the lower side of the connecting frame, both the front and rear sides of the upper end of the connecting frame are fixedly connected with second pressure springs, the top ends of the second pressure springs are fixedly connected to the upper side inside the limiting groove, a pressure sensor is arranged at the right part of the upper end inside the limiting groove, a moving groove is formed inside the hammer body, the limiting groove is located outside the moving groove, an electric push rod is fixedly connected to the upper side inside the moving groove, the telescopic end of the electric push rod is fixedly connected with a first trapezoidal block, the electric push rod is controlled by a control module, and the compression coefficient of the second pressure spring is between 30% and 50%.

[0019] Further, a material blocking assembly is further arranged inside the hammer body, and the material blocking assembly includes a storage cavity formed inside the hammer body, and the storage cavity is located on the left side of the moving groove.

[0020] Further, a blanking pipe is fixedly connected to the lower side inside the storage cavity, and the blanking pipe penetrates through the lower side of the hammer body, and the blanking pipe is communicated with the storage cavity. A baffle is slidably connected to the lower side inside the storage cavity. The baffle blocks the top end of the blanking pipe before moving. Both the front and rear sides of the right end of the baffle are fixedly connected with tension springs. The storage cavity is communicated with the moving groove. A second trapezoidal block is fixedly connected to the right side of the baffle, and the second trapezoidal block is located between the two tension springs. After the first trapezoidal block moves downward, it squeezes and contacts the second trapezoidal block.

[0021] Further, a feeding assembly is jointly arranged on the inner and outer sides of the hammer body, and the feeding assembly includes a conduit inserted inside the hammer body.

[0025] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0026] Through the provided detection module, data processing module, control module, and magnetic attraction module, the present invention can control the percussion force of the percussion block according to the thickness of the patient's skin and subcutaneous tissue. Since the impact force of the percussion block can be controlled by the thickness of the patient's own skin and subcutaneous tissue after the hammer body contacts the patient's limb, even doctors with insufficient experience can quickly master it, and at the same time, it effectively avoids the influence on the examination results caused by too large or too small percussion force.

[0027] Through the provided baffle, when the hammer body approaches the patient's limb, it moves away from the feeding pipe, enabling the feeding pipe to communicate with the storage cavity. Since the storage cavity can be connected to the feeding pipe before the detection module contacts the patient's limb, it is convenient for the detection module to contact the coupling gel, thereby ensuring the detection effect of the detection module on the patient's skin and subcutaneous tissue. Moreover, the coupling gel has a relatively high consistency, which can prevent the coupling gel from leaking.

[0028] Through the provided rubber membrane, after being pressed, it pushes the gas inside the storage tank, causing the coupling gel to accelerate into the storage cavity. Since the supply amount of the coupling gel can be controlled by pressing the rubber membrane, and at the same time, after pressing the rubber membrane, the coupling gel can be accelerated to discharge from the feeding pipe, thereby saving the time consumed by the doctor for examining the patient's limb.

Detailed implementation manner

[0039] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to 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. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0040] Please refer to Figures 1 to 8 , a multifunctional neurology examination device, including a hammer body 1. An activity groove 11 is vertically opened downward inside the hammer body 1. A first pressure spring 12 is fixedly connected to the upper side inside the activity groove 11. The bottom end of the first pressure spring 12 is fixedly connected to a percussion block 13. The lower side of the hammer body 1 is in pressing contact with a chassis 14. A notch 15 is opened on the right side of the inner surface of the chassis 14;

[0041] A detection module 16 is provided on the lower side of the hammer body 1. A data processing module 17 and a control module 18 are respectively provided on the front surface of the hammer body 1 from left to right. A magnetic attraction module 19 is provided on the upper side inside the activity groove 11. The first pressure spring 12 is sleeved outside the magnetic attraction module 19. After the percussion block 13 moves upward, it is in pressing contact with the magnetic attraction module 19.

[0042] The magnetic induction intensity of the magnetic attraction module 19 is between 0.6 and 1.6 teslas, and the compression coefficient of the first pressure spring 12 is between 30% and 50%;

[0043] Detection module 16: An ultrasonic measuring instrument for detecting the thickness of a patient's skin and subcutaneous tissue, which includes an ultrasonic transmitter and an ultrasonic receiver, and transmits the collected data to the data processing module 17;

[0044] Data processing module 17: Used to calculate the thickness of the patient's skin and subcutaneous tissue from the data collected by the detection module 16, and transmit the calculated data to the control module 18 respectively;

[0045] Control module 18: It is used to receive the data transmitted by the data processing module 17, control the magnetic attraction module 19 to generate different suction forces according to different data, and quickly turn off the magnetic attraction module 19 after the percussion block 13 contacts the magnetic attraction module 19;

[0046] Magnetic attraction module 19: It is used to adsorb the percussion block 13 according to the suction force generated by itself;

[0047] The data processing module 17 calculates the thickness of the patient's skin and subcutaneous tissue according to the data transmitted by the detection module 16 through the following formula:

[0048]

[0049] Among them, d is the distance that the ultrasonic wave passes through the patient's skin and subcutaneous tissue, V is the propagation speed of the ultrasonic wave, Δt is the time interval from the emission of the ultrasonic wave to its reflection back and being captured by the receiver, K is a preset coefficient, d is proportional to the product of V and Δt, that is, the longer the time interval, the longer the distance of the patient's skin and subcutaneous tissue. Since the propagation speed of the ultrasonic wave varies in different patients and different skin media, d here is an approximate calculated value. The value of the coefficient K is determined by a large number of previous experiments, so that the thickness d is as close as possible to the actual value of the distance of the patient's skin and subcutaneous tissue. When the thickness of the skin tissue to be detected is between 700 and 2500 microns, the adsorption force intensity on the percussion block 13 is adjusted within the range of 0.1 - 0.5 Mpa, and the adsorption force error is controlled within ±5%;

[0050] By adopting the above technical solution, after the chassis 14 contacts the patient's limb, the detection module 16 also passes through the notch 15 and contacts the patient's limb. At the same time, the detection module 16 collects the thickness data of the patient's skin and subcutaneous tissue through the ultrasonic wave transmitted by the ultrasonic wave transmitter and the ultrasonic wave receiver, and then transmits the collected data to the data processing module 17. After the data processing module 17 calculates the thickness of the skin and subcutaneous tissue at the patient's limb, the data processing module 17 transmits the calculated data to the control module 18, and the control module 18 controls the magnetic attraction module 19 to adsorb the percussion block 13 according to the data transmitted by the data processing module 17;

[0051] It should be noted that as the thickness of the skin and subcutaneous tissue at the limbs of different patients is detected, when the thickness changes, the adsorption time of the magnetic attraction module 19 to the percussion block 13 will also change accordingly, so as to control the height of the percussion block 13 rising to adjust the force of the percussion block 13 hitting the patient's limb. When the thickness of the patient's skin and subcutaneous tissue is thicker, the adsorption time of the magnetic attraction module 19 to the percussion block 13 is longer. After the magnetic attraction module 19 adsorbs the percussion block 13, the distance between the percussion block 13 and the patient's limb will increase. When the magnetic attraction module 19 stops adsorbing the percussion block 13, the percussion block 13 will quickly hit the patient's limb;

[0052] As the magnetic attraction module 19 adsorbs the percussion block 13, the percussion block 13 will slide in the activity groove 11 inside the hammer body 1. At this time, the percussion block 13 will squeeze the first pressure spring 12. When the magnetic attraction module 19 stops adsorbing the percussion block 13, the first pressure spring 12 will be pushed according to its own elastic force and quickly hit the patient's limb. Since the impact force of the percussion block 13 can be controlled by the thickness of the patient's own skin and subcutaneous tissue after the hammer body 1 contacts the patient's limb, even doctors with insufficient experience can quickly master it, and at the same time, it effectively avoids the influence on the examination results caused by too large or too small percussion force.

[0053] As Figures 1 to 4 and Figure 6 shown, a feeding component 2 is provided inside the hammer body 1, and the feeding component 2 includes a limiting groove 21 opened inside the hammer body 1.

[0054] A connecting frame 22 is slidably connected inside the limiting groove 21. The chassis 14 is fixedly connected to the lower side of the connecting frame 22. Both the front and rear sides of the upper end of the connecting frame 22 are fixedly connected with second pressure springs 23. The top ends of the second pressure springs 23 are fixedly connected to the upper side inside the limiting groove 21. A pressure sensor 24 is arranged at the right part of the upper end inside the limiting groove 21. A moving groove 26 is opened inside the hammer body 1. The limiting groove 21 is located outside the moving groove 26. An electric push rod 25 is fixedly connected to the upper side inside the moving groove 26. The telescopic end of the electric push rod 25 is fixedly connected with a first trapezoidal block 27. The electric push rod 25 is controlled by the control module 18. The compression coefficient of the second pressure spring 23 is between 30% - 50%.

[0055] A material blocking component 28 is also provided inside the hammer body 1. The material blocking component 28 includes a storage cavity 281 opened inside the hammer body 1. The storage cavity 281 is located on the left side of the moving groove 26.

[0056] A material discharging pipe 282 is fixedly connected to the lower side inside the storage cavity 281, and the material discharging pipe 282 penetrates through the lower side of the hammer body 1. The material discharging pipe 282 is communicated with the storage cavity 281. A baffle 283 is slidably connected to the lower side inside the storage cavity 281. Before moving, the baffle 283 blocks the top end of the material discharging pipe 282. Tension springs 285 are fixedly connected to both the front and rear sides of the right end of the baffle 283. The storage cavity 281 is communicated with the moving groove 26. A second trapezoidal block 284 is fixedly connected to the right side of the baffle 283, and the second trapezoidal block 284 is located between the two tension springs 285. After the first trapezoidal block 27 moves downward, it comes into pressing contact with the second trapezoidal block 284.

[0057] By adopting the above technical solution, when the chassis 14 contacts the patient's limb, the doctor presses the hammer body 1. At this time, the connecting frame 22 fixed to the chassis 14 slides inside the limiting groove 21 and presses the second compression spring 23. At the same time, the connecting frame 22 presses the gas inside the limiting groove 21, and the gas will move toward the pressure sensor 24 after being pressed and press the pressure sensor 24. Subsequently, after the pressure sensor 24 transmits the information to the control module 18, the control module 18 controls the electric push rod 25 to pull the first trapezoidal block 27 upward. As the first trapezoidal block 27 moves inside the moving groove 26, the first trapezoidal block 27 gradually separates from the second trapezoidal block 284 on the right side of the baffle 283. At this time, the tension spring 285 will pull the baffle 283, causing the baffle 283 to gradually move away from above the material discharging pipe 282, resulting in the communication between the storage cavity 281 and the material discharging pipe 282. At this time, the coupling gel inside the storage cavity 281 can be discharged from the material discharging pipe 282 and enter the area of the notch 15, so that the detection module 16 contacts the coupling gel before contacting the patient's limb. When the hammer body 1 moves away from the patient, the second compression spring 23 inside the limiting groove 21 pushes the connecting frame 22. At this time, the electric push rod 25 starts to move in the reverse direction and pushes the first trapezoidal block 27 to gradually contact the second trapezoidal block 284. When the two contact, the second trapezoidal block 284 will push the baffle 283 toward the direction of the material discharging pipe 282 and stretch the tension spring 285, and the baffle 283 will block the material discharging pipe 282 again. Since the storage cavity 281 and the material discharging pipe 282 can be communicated before the detection module 16 contacts the patient's limb, it is convenient for the detection module 16 to contact the coupling gel, thereby ensuring the detection effect of the detection module 16 on the patient's skin and subcutaneous tissues. And the coupling gel itself has a high consistency, which can prevent the coupling gel from leaking.

[0058] As Figures 1 to 4 shown, a feeding assembly 29 is provided jointly inside and outside the hammer body 1. The feeding assembly 29 includes a conduit 291 inserted inside the hammer body 1.

[0059] A docking cavity 292 is provided on the right side of the hammer body 1. The bottom end of the conduit 291 communicates with the storage cavity 281, and the top end of the conduit 291 communicates with the docking cavity 292. A storage tank 293 is rotatably connected inside the docking cavity 292. The docking cavity 292 communicates with the storage tank 293. A rubber membrane 294 is provided on the outer side of the storage tank 293, and a grip 295 is fixedly connected to the lower side of the rubber membrane 294.

[0060] By adopting the above technical solution, the doctor connects the storage tank 293 to the hammer body 1 through the docking cavity 292, and then holds the storage tank 293. Since one end of the conduit 291 provided inside the hammer body 1 communicates with the storage cavity 281 and the other end communicates with the docking cavity 292, when the doctor squeezes the rubber membrane 294 below the storage tank 293 through the grip 295, as the storage tank 293 communicates with the hammer body 1, the amount of gas inside the storage tank 293 remains fixed. If the rubber membrane 294 is squeezed, the gas inside the storage tank 293 will push the coupling gel, causing the coupling gel to enter the storage cavity 281 through the conduit 291. If the baffle 283 leaves the feed pipe 282, the coupling gel entering the storage cavity 281 will squeeze the coupling gel below it, causing the coupling gel to accelerate and discharge from the feed pipe 282. Since the supply amount of the coupling gel can be controlled by pressing the rubber membrane 294, and the coupling gel can be accelerated to discharge from the feed pipe 282 after pressing the rubber membrane 294, the time consumed by the doctor for examining the patient's limb is saved.

[0061] As Figures 1 to 3 shown, an inspection component 3 is jointly provided on the inner and outer sides of the hammer body 1. The inspection component 3 includes a receiving groove 31 opened on the upper side of the hammer body 1.

[0062] A sleeve 33 is slidably connected inside the receiving groove 31. A third compression spring 32 is fixedly connected between the sleeve 33 and the lower side inside the receiving groove 31 in an annular array. A tactile needle 34 is provided on the upper side of the hammer body 1. The sleeve 33 is located outside the tactile needle 34. The length of the tactile needle 34 is between 0.5 - 1 cm, and the puncture skin thickness range is controlled between 50 - 1000 microns.

[0063] By adopting the above technical solution, after the hammer body 1 is flipped, the sleeve 33 will face the patient's limb. After the sleeve 33 contacts the patient's limb, the hammer body 1 is installed continuously. Since the tactile needle 34 inside the sleeve 33 is fixed to the hammer body 1, and the sleeve 33 slides in the receiving groove 31 through the third compression spring 32. After gently pressing the hammer body 1, the sleeve 33 retracts into the receiving groove 31, and the tactile needle 34 pierces the patient's limb. If the hammer body 1 leaves the patient, the third compression spring 32 will push the sleeve 33 out of the receiving groove 31, so that the sleeve 33 wraps the tactile needle 34 again. Since the sleeve 33 always wraps outside the tactile needle 34 before the tactile needle 34 evaluates the patient's tactile sensitivity, it can avoid the tactile needle 34 from causing damage to doctors and other staff, and can also prevent the tactile needle 34 from being damaged itself. The hammer body 1 can be used for different examinations before and after flipping, reducing the preparation work for doctors when examining patients.

[0064] Working principle: The doctor connects the storage tank 293 to the hammer body 1 through the docking cavity 292. Then, hold the storage tank 293 and squeeze the rubber film 294 below the storage tank 293 through the grip 295. The gas inside the storage tank 293 will push the coupling gel, so that the coupling gel enters the storage cavity 281 through the conduit 291. When the chassis 14 contacts the patient's limb, the detection module 16 also passes through the notch 15 and contacts the patient's limb. At the same time, the detection module 16 collects the thickness data of the patient's skin and subcutaneous tissue through the ultrasonic waves transmitted by the ultrasonic transmitter and the ultrasonic receiver. Then, the collected data is transmitted to the data processing module 17. After the data processing module 17 calculates the thickness of the skin and subcutaneous tissue at the patient's limb, the data processing module 17 transmits the calculated data to the control module 18. The control module 18 controls the magnetic attraction module 19 to adsorb the percussion block 13 according to the data transmitted by the data processing module 17. As the magnetic attraction module 19 adsorbs the percussion block 13, the percussion block 13 will slide in the activity slot 11 inside the hammer body 1. At this time, the percussion block 13 will squeeze the first pressure spring 12. When the magnetic attraction module 19 stops adsorbing the percussion block 13, the first pressure spring 12 will be pushed according to its own elasticity and quickly strike the patient's limb. At the same time, the connecting frame 22 fixed to the chassis 14 slides inside the limit slot 21 and squeezes the second pressure spring 23. Then, the connecting frame 22 squeezes the gas inside the limit slot 21, and the gas will move toward the pressure sensor 24 after being squeezed and squeeze the pressure sensor 24. Then, the pressure sensor 24 controls the electric push rod 25 to pull the first trapezoidal block 27 upward through the control module 18. At this time, the tension spring 285 will pull the baffle 283, so that the baffle 283 gradually leaves from above the material discharge pipe 282, resulting in the communication between the storage cavity 281 and the material discharge pipe 282. At this time, the coupling gel inside the storage cavity 281 can be discharged from the material discharge pipe 282 and enter the area of the notch 15, so that the detection module 16 contacts the coupling gel before contacting the patient's limb. When the hammer body 1 is away from the patient, the second pressure spring 23 pushes the connecting frame 22. At this time, the electric push rod 25 starts to move in the reverse direction and pushes the first trapezoidal block 27 to gradually contact the second trapezoidal block 284 and pull the tension spring 285, and the baffle 283 will cover the material discharge pipe 282 again. When the hammer body 1 is turned over, the sleeve 33 will face the patient's limb. After the sleeve 33 contacts the patient's limb, the hammer body 1 is installed continuously. Since the tactile needle 34 inside the sleeve 33 is fixed to the hammer body 1, and the sleeve 33 slides in the receiving groove 31 through the third pressure spring 32. After gently pressing the hammer body 1, the sleeve 33 retracts into the receiving groove 31, and the tactile needle 34 pierces the patient's limb. If the hammer body 1 leaves the patient, the third pressure spring 32 will push the sleeve 33 out of the receiving groove 31, so that the sleeve 33 wraps the tactile needle 34 again.

[0065] The above are only the preferred specific embodiments of the present invention; however, the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its improved concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
