Description

Neurological examination device

Technical Field

The present invention relates to the technical field of neurology examination, in particular to a neurology examination device.

Background technique

As the number of neurological diseases increases, medical staff need to examine patients' sense of touch. The feeling produced by skin contact is called touch, and examining patients' sense of touch is a common examination method in neurology.

For example, Chinese patent CN202210232627.4 discloses a handheld clinical tapping examination device for neurology. It can be seen that by providing a tapping mechanism, the tapping group in the tapping mechanism is convenient for performing tapping examinations on patients, and while the tapping group is operating, the elastic scale of the elastic indication group is indicated, which is convenient for displaying the force generated by the tapping and improving the accuracy of the tapping examination. By providing a reciprocating tapping drive mechanism, automatic reciprocating tapping examinations can be achieved, and the first drive group is driven to operate by the second drive group. Under the action of the elastic reset group, the first drive group achieves tapping examination operations at a certain rate, and the use effect is good, and it has the advantages of being easy to use and capable of automatic tapping examinations.

Another example is a neurological reflex examination device disclosed in CN202110802839.7. It can be seen that when a percussion hammer is needed, the main body mechanism can be rotated by hand first, which makes it easier to adjust the length of the main body mechanism. When in use, the knocking mechanism slides inside the main body mechanism, which makes it easier to shock and relieve pressure on the main body mechanism while preventing the doctor from knocking too hard and causing discomfort to the patient. When the operator installs the knocking mechanism, the fixing mechanism is squeezed, so that the fixing mechanism contacts the suspension mechanism when sliding inside the main body mechanism, thereby facilitating the installation of the knocking mechanism and making the suspension mechanism more firmly engaged.

Based on the search of existing technologies, most medical staff use a detection hammer or detection rod to touch the skin and then ask the patient about the tactile feeling. Manual operation is not only time-consuming and laborious, but also requires the medical staff to rely on their own experience to control the strength and inspection area, resulting in poor practicality.

Furthermore, when using an inspection device, it may not be possible to inspect arms of different thicknesses, and the contact strength between the skin is not adjustable, and it is difficult to inspect different positions on the arm, resulting in poor overall inspection effect and efficiency.

Detailed ways

The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. 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.

Embodiment 1:

Please refer to Figures 1 to 6. This embodiment provides a technical solution: a neurological examination device, including: a base 1, an inspection port, an inspection box 2, a support ring 4, a detection rod 5, a driving mechanism, a linkage mechanism and a connecting mechanism.

More specifically, in this embodiment: when in use, first place or install the device in a suitable area, then the user extends the arm to be tactilely sensed into the interior of the inspection box 2 through the inspection port, and then the medical staff observes on the side. When the placement is observed, the drive mechanism is operated through the control panel, and the drive mechanism drives the linkage mechanism and the connecting mechanism to operate, so that the two sets of symmetrically arranged detection rods 5 can finally perform intermittent orbital and reciprocating motion to touch multiple areas of the arm. This is different from other neurological examination methods, which mostly use manual control of the detection rod to touch the skin, and need to rely on experience to control the area and strength of the tapping. This method can intelligently perform directional touching on multiple areas on the arm in an intermittent form, so that the patient can fully perceive and improve the accuracy of the examination.

It is worth noting that the present embodiment also includes: an adjusting component, a rubber pad is fixedly installed on the inner side of the support ring 4, the side of the mounting ring 30 is fixedly connected to the outer side of the inspection port, the inner side of the mounting ring 30 is fixedly connected to bristles, the outer surface of the mounting ring 30 is fixedly connected to a mounting shell 31, the outer surface of the mounting shell 31 is fixedly installed with a blowing device 32, the blowing end of the blowing device 32 is connected to the inner cavity of the mounting shell 31, and the inner side of the mounting shell 31 is fixedly connected with a nozzle.

More specifically, in this embodiment: the operation of the adjustment component can make the device usable for examining patients with different arm thicknesses, and can also control different touch forces, so that the examination results are more accurate, and can enable medical staff to quickly understand the user's perception. And through the use of rubber pads, it can support and protect the arm to improve comfort. The operation of the blowing device 32 can make the nozzle spray dust toward the arm entering the inspection box 2, and at the same time, the bristles can fully contact the arm entering the inspection box 2, so that the dust can be brushed off, so as to avoid dust and impurities entering the inspection box 2 and contaminating the inspection box 2, and avoid affecting the subsequent normal neurological examination of touch perception.

Embodiment 2:

Based on the above embodiments:

Please refer to FIG. 1 , FIG. 2 and FIG. 3 , the driving mechanism in the first embodiment is disclosed as follows, and the driving mechanism includes:

Motor 1 6, the outer shell of motor 1 6 is fixedly connected to the side of the inspection box 2, the rotating part of motor 1 6 is fixedly connected to a rotating rod 7, and the inner wall of the inspection box 2 is fixedly connected to a rotating shaft 8.

More specifically, in this embodiment: when in use, the user operates on the control panel, the control panel will drive the motor 1 6 to operate, and the rotating part of the motor 1 6 will drive the rotating rod 7 to rotate.

Embodiment three:

Based on the above embodiments:

Please refer to FIG. 1 , FIG. 2 , FIG. 3 , FIG. 4 and FIG. 6 , the linkage mechanism in the first embodiment is disclosed as follows, and the linkage mechanism includes:

The bracket 9, the end of the bracket 9 is fixedly connected to the inner wall of the inspection box 2, the inner side of the bracket 9 is rotatably connected with a ring body 10, the side of the ring body 10 is fixedly connected with two cross plates 11, the inner side of the ring body 10 is fixedly connected with four limiting grooves 12 and four limiting blocks 13, the end of the rotating rod 7 is fixedly connected with a rotating block 14, the end of the rotating block 14 is fixedly connected with a connecting plate 15, the side of the connecting plate 15 is fixedly connected with a sliding column 16, the side of the sliding column 16 slides with the groove wall of the limiting groove 12, and the end of the limiting block 13 facing the center of the ring body 10 is in contact with the arc portion of the rotating block 14.

More specifically, in this embodiment: the rotation of the rotating rod 7 drives the rotating block 14, the connecting plate 15 and the sliding column 16 to rotate synchronously. When the sliding column 16 enters the limiting groove 12, the arc portion of the rotating block 14 is separated from the limiting block 13. Since the sliding column 16 revolves around the rotating rod 7, the sliding column 16 presses against the groove wall of the limiting groove 12, thereby giving the ring body 10 a rotational force, thereby driving the ring body 10 to rotate. When the arc portion of the rotating block 14 fits with the end of the next limiting block 13, the rotation of the ring body 10 can be restricted, thereby achieving a stopping effect, and finally achieving the form of intermittent rotation of the ring body 10, the two horizontal plates 11 and the detection rod 5. This method has the following advantages:

First, because everyone has different degrees of reaction to tactile perception, if the patient's arm is touched in the form of continuous revolution, young people may be able to react in time, but some patients or elderly people may not be able to perceive the local position in time and immediately turn to touch the other part of the arm, resulting in low efficiency and poor accuracy of neurological examinations. This method adopts the form of intermittent rotation, so that multiple touches can be made at one position. After the patient fully perceives, the medical staff will make corresponding records, and then switch to other positions for touching again, so that the detection rod 5 can fully touch a certain position of the user's arm to improve the detection effect and the accuracy of the examination;

Second, two sets of opposite detection rods 5 are used, so that two opposite positions of the patient's arm can be touched at the same time, so that the patient can have a quick tactile perception, thereby improving the efficiency of the examination;

In order to achieve the purpose of all-round tactile perception inspection, the user can rotate the arm appropriately and then touch the arm while reciprocating intermittently, so that more areas on the arm can be touched.

Embodiment 4:

Based on the above embodiments:

Please refer to FIG. 1 , FIG. 2 , FIG. 3 , FIG. 4 and FIG. 5 , the connection mechanism in the first embodiment is disclosed as follows, and the connection mechanism includes:

Two rotating rods 17 and a mounting seat 18 are fixedly connected on the outer surface of the horizontal plate 11, and an opening 1 is provided on the side of the mounting seat 18 for the rotating rod 17 to pass through and is connected to the fixed axis rotation. The two rotating rods 17 are connected to the rotating shaft 8 through a double-groove pulley transmission mechanism 35. A gear 19 is fixedly connected on the outer surface of the rotating rod 7, and a gear 20 is fixedly connected on the outer surface of the rotating shaft 8. The specification of gear 19 is larger than that of gear 20. The center portion of one side of the disk 21 is fixedly connected to the end of the rotating rod 17, and the other side of the disk 21 is fixedly connected to a fixed column 22. An opening 2 is provided on the outer surface of the horizontal plate 11, and a slide plate 23 is slidably connected to the mouth wall of the opening 2. One end of the slide plate 23 is fixedly connected to an annular groove 24, and the inner side of the annular groove 24 is slidably connected to the outer surface of the fixed column 22, and the other end of the slide plate 23 is fixedly connected to the mounting seat 25.

More specifically, in this embodiment: when in use, the rotation of the rotating rod 7 drives the gear 19 to rotate, and drives the gear 2 20 and the rotating shaft 8 to rotate under the meshing transmission, and then drives the two rotating rods 17 and the disk 21 to rotate under the connection transmission of the double-groove pulley transmission mechanism 35, and drives the fixed column 22 thereon to revolve around the rotating rod 17 as the center of the circle during the rotation, and due to the sliding restriction of the opening 2 on the slide plate 23, and the sliding restriction relationship between the fixed column 22 and the annular groove 24, the fixed column 22 will continuously slide in the annular groove 24, and then can drive the annular groove 24, the slide plate 23, the mounting seat 25 and the detection rod 5 thereon to reciprocate vertically, so that the detection rod 5 touches the patient's arm, and then the user asks the patient about his own tactile feeling, and the neurological examination of the patient can be completed. This method has the following advantages:

First, it can continuously touch the patient's arm in a reciprocating manner, so that the patient can perceive the touch, replacing the manual tapping process, thereby using a mechanized method to achieve the purpose of neurological examination, and the strength of the mechanized intelligent operation can be quantitatively controlled, which is different from the uneven strength when the doctor taps manually based on experience, so the examination effect of this method is better;

Second: It can touch the arm while revolving and rotating, so that it can touch the arm in all directions, which can improve the comprehensiveness and efficiency of neurological examinations, and can examine multiple areas to reduce examination errors, so that doctors can fully understand the patient's tactile perception;

Thirdly, the connection mechanism is operated faster by adopting the transmission mode of large and small gears. Since the transmission ratios of the large and small gears are different, when the detection rod 5 intermittently revolves, the detection rod 5 can touch the patient's arm skin multiple times, so that the patient can fully perceive it, so as to avoid the situation where the contact time is short and the patient's perception is poor.

Embodiment five:

Based on the above embodiments:

Please refer to FIG. 1 , FIG. 2 , FIG. 3 , FIG. 4 and FIG. 5 , the adjustment component in the first embodiment is disclosed as follows, and the adjustment component includes:

There are two sliding seats 26, and a sliding opening is provided on the outer surface of the mounting seat 25 for the sliding seat 26 to penetrate and be slidably connected thereto. The detection rod 5 is installed on the side of the sliding seat 26 facing the rotating shaft 8. A motor 27 is fixedly connected to the outer surface of the mounting seat 25, and a screw 28 is fixedly connected to the rotating part of the motor 27. An internal thread groove is provided on the outer surface of the sliding seat 26 for the screw 28 to penetrate and be threadedly connected thereto.

More specifically, in this embodiment: when in use, the control panel can operate the rotating part of the motor 27 to operate, and the rotating part of the motor 27 will drive the screw 28 to rotate. Under the thread transmission and the sliding restriction of the mounting seat 25, the detection rod 5 on the sliding seat 26 can adjust the displacement, and then can move closer to or away from the user's arm. With the reciprocating motion of the detection rod 5, the user's arm can be continuously touched and pressed. This method has the following advantages:

Because the thickness of users' arms varies in actual use, if the detection rod 5 is not adjustable, the detection rod 5 may not touch the arm or the contact force with the arm may be too large, resulting in poor inspection results and injury to the user. Therefore, this method is not only suitable for tactile perception examinations of neurology for arms of different thicknesses, but also can control the detection strength of the detection rod 5 and the arm, thereby checking the patient's perception level and improving the accuracy of neurology examinations.

Working principle: The neurological examination device has the following steps when used:

Step S1: First, the user installs the device on a suitable plane, and then the patient extends his arm into the inspection box 2 through the inspection port, and the arm is supported by the support ring 4;

Step S2: After the user observes that the patient's arm is placed, he can operate on the control panel, which will operate the adjustment component. The user can adjust the distance between the detection rod 5 and the patient's arm according to the thickness of the patient's arm and the strength required to touch the arm;

Step S3: Then the control panel will control the driving mechanism to operate, and the driving mechanism will drive the linkage mechanism and the connecting mechanism to operate, so as to drive the two sets of detection rods 5 to reciprocate while revolving to continuously touch the patient's arm at multiple angles, and have an intermittent rotation form, so as to achieve the form of multiple touches on the local position;

Step S4: The patient's arm can be touched cyclically and continuously, and then the user asks the patient about his or her perception, thereby completing a neurological examination of the patient.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
