Description

Technical Field

[0001] The utility model relates to a sensory detection device, in particular to a multi-purpose sensory detection device. Background Art

[0002] Sensation refers to the human brain's response to individual attributes of objective objects that directly act on the sensory organs. Individual attributes include size, shape, color, firmness, humidity, taste, smell, sound, etc. Depending on the response of the receptors to stimuli or the location of the receptors, somatic sensations are divided into superficial sensations, deep sensations, and complex sensations. Superficial sensations include touch, pain, temperature, and pressure; deep sensations include position, movement, and vibration; and complex sensations include skin positioning, two-point discrimination, stereopsis, and pattern perception. Patients with stroke, brain trauma, peripheral nerve damage, and skin grafting often experience various sensory impairments or losses, which seriously affect the recovery of sensory function. Therefore, accurate assessment of sensation is very important for recovery.

[0003] Currently, tactile sensation is assessed by lightly touching the patient's skin with a cotton swab or soft brush and asking the patient to answer whether they experience a slight itchy sensation or to count the number of times they are touched. Tactile examinations are divided into qualitative and quantitative tests. Cotton swabs or soft brushes can only be used for qualitative examinations, while quantitative examinations currently use Semmes-Weinstein monofilaments of varying specifications. Pain sensation is assessed by stimulating the patient's normal skin area several times with the tip of a pin, allowing the patient to experience the sensation of normal stimulation. Vibration sensation is assessed with the patient closing their eyes. The examiner places a tuning fork that vibrates 256 times per second on a bony protrusion, such as a finger, ulnar styloid process, or olecranon, and asks the patient whether they experience the vibration and how long it lasts. Two-point discrimination, a complex sensation, is assessed by lightly touching the skin simultaneously with the two tips of a caliper or percussion hammer, or the tip of a needle, from largest to smallest distance, to measure the minimum distance that can distinguish the two points. The aforementioned sensory assessments require instruments such as cotton swabs, soft brushes, pins, tuning forks, calipers, and percussion hammers. Quantitative testing of tactile sensation requires Semmes-Weinstein monofilaments of various sizes. The large number of items required for pre-examination preparations presents significant challenges for clinical sensory assessment. Therefore, a device that can simultaneously assess various types of sensory impairments is urgently needed to facilitate clinical application. Utility Model Content

DETAILED DESCRIPTION

[0016] The present invention will be further described below with reference to the accompanying drawings.

[0017] 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 embodiments described 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 making creative efforts are within the scope of protection of the present invention.

[0018] like Figures 1 to 3As shown, the utility model provides a technical solution: it includes a handle 1 and an end head 2, the front end of the handle 1 is connected to the middle part of the end head 2, and a tuning fork 3 is provided on the top of the end head 2 for evaluating the patient's vibration sense; a plurality of circular countersunk holes 4 are opened from the bottom surface of the end head 2 to the inside thereof at equal intervals along the outer circumference of the end head 2, and the bottom diameter of the circular countersunk hole 4 gradually decreases, corresponding to the position of the upper half of the circular countersunk hole 4, a guide groove 5 is opened from the outer surface of the end head 2 to the inside thereof, the guide groove 5 is connected with the circular countersunk hole 4, and a plurality of slots 6 are opened at longitudinal intervals on the side of the guide groove 5, a sliding column 7 and a spring 9 are provided in the circular countersunk hole 4, the bottom end of the sliding column 7 is clamped with the top end of the spring 9, and a clamping block 8 adapted to the size of the slot 6 is provided on the outer side surface of the top of the sliding column 7, and a test element 10 is provided at the center of the bottom end face of the sliding column 7. Since the bottom diameter of the circular countersunk hole 4 gradually decreases, the bottom end of the spring 9 is clamped with the bottom of the circular countersunk hole 4, and the spring 9 will not slide out from the bottom of the circular countersunk hole 4. When the test element 10 is completely located in the circular countersunk hole 4, that is, the bottom end of the test element 10 will not be exposed outside the circular countersunk hole 4; when the test element 10 needs to be used to evaluate the patient's superficial sensation, the card block 8 is pressed down to the corresponding card slot 6, and then the card block 8 is rotated in the direction of the card slot 6. Since the circular countersunk hole 4 and the slide post 7 are both circular, the slide post 7 can rotate relative to each other in the circular countersunk hole 4, and finally the card block 8 is embedded in the card slot 6, thereby preventing the spring 9 from rebounding and bouncing the slide post 7 back to the initial state. Pressing the card block 8 will drive the slide post 7 to move downward and make the test element 10 extend out of the circular countersunk hole 4 for the patient's superficial sensation evaluation. After the evaluation, the card block 8 is rotated in the opposite direction to disengage it from the limit of the card slot 6. At this time, the spring 9 rebounds and bounces the slide post 7 back to its initial state.

[0019] To ensure consistent operation when assessing a patient's superficial sensation, a stopper ball 201 is located at the center of the bottom surface of the tip 2. From the moment the test element 10 contacts the patient's skin, the tester presses downward until the stopper ball 201 makes contact, ensuring consistent operation and accurate assessment. To meet the requirements for general superficial sensation assessment, at least seven circular countersunk holes 4 are provided, each containing a pin, a soft hair, and at least five Semmes-Weinstein monofilaments of varying sizes. When the desired test element 10 is used, simply press it downward to remove it.

[0020] The handle 1 includes a lower handle 101, an upper handle 102, a hinge plate 103 and a connecting handle 105. The inner end of the lower handle 101 and the inner end of the upper handle 102 are hinged together through the hinge plate 103, and the hinge plate 103 is connected to the end 2 through the connecting handle 105; the lower handle 101 and the upper handle 102 can be rotated with the hinge plate 103 as the hinge point to open or close. When the lower handle 101 and the upper handle 102 are closed, the handle 1 is directly used as a holding handle; when the lower handle 101 and the upper handle 102 are opened, the lower handle 101 and the upper handle 102 form a device similar to a bipod, that is, this The handle 1 is used as a bipod to check the two-point discrimination sense in the patient's complex sensation. In order to facilitate the examiner to intuitively know the distance between the two legs of the bipod, scale lines 104 are provided on the surface of the hinged disk 103. The current distance between the outer ends of the lower handle 101 and the upper handle 102 can be directly read through the scale lines 104 corresponding to the lower handle 101 and the upper handle 102. In order to enhance the sense of contact, a protrusion 106 is respectively provided on the outer ends of the lower handle 101 and the upper handle 102, and the protrusion 106 replaces the outer ends of the lower handle 101 and the upper handle 102 to contact the patient's skin.

[0021] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be embodied in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.

[0022] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
