Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0019] See also Figure 1-5The present invention provides a technical solution: an automated neurology knee jerk reaction efficient detection device, comprising an adjustable leg sleeve pad, an angle adjuster, a lateral guide assembly, a knocker and a reaction timing mechanism, the adjustable leg sleeve pad comprising a sleeve pad 1, a telescopic sleeve 2 and a sleeve pad 2 3, the sleeve pad 1 and the sleeve pad 2 3 are connected by the telescopic sleeve 2, the angle adjuster is divided into two groups and symmetrically installed on both sides of the sleeve pad 1, the angle adjuster comprises a mounting plate, a motor 4, a driving gear 5, a driven gear 6 and a connecting rod 7, the mounting plate is fixed on the sleeve pad 1, the motor 1 4 is mounted on the mounting plate and the power output end is connected to the driving gear 5, the driving gear 5 is meshed with the driven gear 6, the driven gear 6 is connected to the connecting rod 7, the upper ends of the two groups of connecting rods 7 are connected to the lateral guide assembly, the lateral guide assembly comprises a guide rod 8, a motor 2 9, a screw 10, a slider 11 and a moving ring 12, both ends of the guide rod 8 are connected to the two groups of connecting rods The connecting rod 7 is rotatably connected, and a slide groove 13 is provided on the surface of the guide rod. The motor 2 9 is installed at one end of the slide groove 13 and the power output end is connected to the screw 10. The screw 10 is rotatably set in the slide groove 13. The slider 11 is threadedly inserted into the screw 10 and the outer end is connected to the moving ring 12. The lower end of the moving ring 12 is connected to the knocker. The knocker consists of two parts, namely a knocking ball 14 and a driver 15 used in conjunction with the knocking ball 14. The knocking ball 14 is installed on the moving ring 12, and the driver 15 is installed on the upper end of the connecting rod 7. The reaction timing mechanism includes a vibration sensor 16 installed in the knocking ball 14 and a controller 17 connected to the vibration sensor 16 through a line. The controller 17 is connected to a timer 18 and a detachment detector 19. The detachment detector 19 is installed between the sleeve pad 1 and the sleeve pad 2 3. The device is also used in conjunction with a floating adjuster 20, and the floating adjuster 20 is installed on the seat.
[0020] Further improvement, such as Figure 2 As shown, the telescopic sleeve 2 is made of rubber material and has a plurality of groups of deformation adjustment grooves 21 formed on the surface. The plurality of groups of deformation adjustment grooves 21 are distributed in a stacked manner, so as to facilitate the patient to make a knee-jerk reaction.
[0021] Further improvement, such as Figure 3 As shown, the knocking ball 14 includes a vertical rod 22 and a weighted ball 23 fixed to the lower end of the vertical rod 22. The weighted ball 23 has an inner cavity, and the vibration sensor 16 is built into the inner cavity. Every time the knocking ball 14 knocks on the patient's knee tendon, the vibration sensor 16 can sense it and transmit the signal to the controller 17.
[0022] Further improvement, such as Figure 2As shown, the driver 15 includes a motor three 24 and a rotating disk 25 installed at the power output end of the motor three 24, a toggle protrusion 26 is fixed to the edge of the rotating disk 25, a swing rod 27 is arranged on one side of the toggle protrusion 26, the upper end of the swing rod 27 is connected to the guide rod 8, the swing rod 27 is used in conjunction with the toggle protrusion 26, and the rotating disk 25 is driven to rotate by the motor three 24. During the rotation of the rotating disk 25, the toggle protrusion 26 acts on the swing rod 27, and the swing rod 27 flips under the thrust of the toggle protrusion 26, so that the guide rod 8 together with the knocking ball 14 can be flipped and lifted. When the toggle protrusion 26 is separated from the swing rod 27, the knocking ball 14 falls under the action of gravity and knocks the patient's knee tendon.
[0023] Further improvement, such as Figure 2 As shown, the toggle protrusion 26 is fan-shaped and the width of one end is smaller than the width of the other end. The rotation of the guide rod 8 can be adjusted by the toggle protrusion 26 acting on the swing rod 27.
[0024] Further improvement, such as Figure 4 As shown, the detachment detector 19 includes a disk body 28 and a contact rod 29 installed on the disk body 28 in an inclined state. The disk body 28 is installed on the sleeve gasket 3. The outer end of the contact rod 29 is provided with a detection disk 30. The detection disk 30 is installed on the sleeve gasket 1, and the contact rod 29 is inserted into the detection disk 30.
[0025] Further improvement, such as Figure 4 As shown, the detection disk 30 includes a shell 31, a floating spring 32, a floating contact 33 and a powered contact 34. A slot 35 is provided at the lower left corner of the shell 31. The floating spring 32 is a stacked structure and is located in the slot 35. The inner side of the floating spring 32 is connected to the floating contact 33. The powered contact 34 is divided into two groups and is symmetrically arranged on both sides of the floating contact 33. The powered contact 34 is connected to the controller 17 through a line. When the patient makes a knee-jerk reaction, the contact rod 29 disengages from the floating spring 32. When the floating spring 32 loses pressure, the floating spring 32 drives the floating contact 33 to move outward, and makes the floating contact 33 contact with the two groups of powered contacts 34 to form a passage. At this time, the controller 17 obtains the model and controls the timer 18 to stop timing. At this time, it is the reaction time of a knee-jerk reaction.
[0026] Specifically, the floating adjuster 20 includes a support pad 36 rotatably mounted on the seat and an electric push rod 37 arranged under the support pad 36. The electric push rod 37 is fixed on the seat and the power output end is in contact with the outer end of the support pad 36. When the patient needs to perform a knee jerk reaction test, the patient sits on the seat and places the thigh on the support pad 36. The support pad 36 is pushed to rotate by the electric push rod 37 as needed, so that the height of the support pad 36 can be adjusted and the patient's legs can be raised to facilitate subsequent testing.
[0027] During use: When it is necessary to perform a knee jerk reaction test on the patient, the patient sits on the chair and places the thigh on the support pad 36. The support pad 36 can be pushed and rotated by the electric push rod 37 as needed, so that the height of the support pad 36 can be adjusted and the patient's leg can be raised. At this time, the knee tendon is searched, and the driving gear 5 is driven to rotate by the motor 1 4. During the rotation, the driving gear 5 drives the driven gear 6 and the connecting rod 7 to rotate. The connecting rod 7 drives the lateral guide component and the knocker to adjust the rotation position. At the same time, the motor 2 9 drives the screw 10 to rotate, thereby driving the slider 11, the moving ring 12 and the knocking ball 14 to move laterally. During the adjustment process, the knocking ball 14 continuously knocks on the patient's knee tendon. When the detachment detector 19 reacts, this is the reaction position of the knee tendon. The rotating disk 25 is driven to rotate by the motor 3 24. The rotating disk 25 During the rotation, the swing rod 27 is acted on by the toggle protrusion 26. The swing rod 27 flips under the thrust of the toggle protrusion 26, and the guide rod 8 together with the knocking ball 14 can be flipped and lifted. When the toggle protrusion 26 is separated from the swing rod 27, the knocking ball 14 falls under the action of gravity and knocks the patient's knee tendon. Every time the knocking ball 14 knocks the patient's knee tendon, the vibration sensor 16 can sense it and transmit the signal to the controller 17. The controller 17 controls the timer 18 to start timing. When the patient makes a knee jerk reaction, the contact rod 29 is separated from the floating spring piece 32. When the floating spring piece 32 loses pressure, the floating spring piece 32 drives the floating contact 33 to move outward, and makes the floating contact 33 contact with the two groups of energized contacts 34 to form a path. At this time, the controller 17 obtains the model and controls the timer 18 to stop timing. This is the reaction time of a knee jerk reaction.
