Abstract
Description
Technical Field
[0001] The present invention relates to the field of medical devices, and in particular to a device for detecting diabetic peripheral neuropathy. Background Art
[0002] Diabetes is a metabolic disease characterized by high blood sugar levels. Symptoms such as diabetic peripheral neuropathy often appear too late. Long-standing high blood sugar levels can lead to microvascular and macrovascular damage, as well as neuropathy. Approximately half of diabetic patients will develop distal symmetrical polyneuropathy, with symptoms including hyperalgesia, numbness in the extremities, and sensory loss. Painless neuropathy, in particular, is caused by the loss of protective sensations (pain, touch, and position sense). Small, imperceptible foot skin injuries often lead to the development and aggravation of foot ulcers, which can lead to uncontrollable amputation and disability. Failure to promptly diagnose and treat the condition can severely impact the patient's quality of life.
[0003] Current guidelines for screening diabetic peripheral neuropathy recommend screening for vibration sensation, pressure sensation, pinprick pain, and tendon reflexes, requiring a variety of tools, including tuning forks, 10g nylon filaments, pins, and percussion hammers. Existing examination methods require a variety of tools, many of which are neurological examination tools. These tools provide unclear indications of the diabetic neuropathy examination site. The large number of instruments makes them inconvenient to carry and can easily be missed or lost. They also require frequent replacements, which is cumbersome and has certain adverse effects on practical use. Therefore, a portable, functional, and integrated peripheral neuropathy examination tool is needed. Summary of the Invention
[0004] The present invention aims to provide a device for examining diabetic peripheral neuropathy, so as to provide a peripheral neuropathy examining tool which is easy to carry and has integrated functions.
[0005] To achieve the above-mentioned purpose, the present invention adopts the following technical solution: a diabetic peripheral neuropathy inspection device, comprising a tuning fork part and a detection hammer part, the tuning fork part comprising a fork handle and two fork arms arranged on the fork handle, the detection hammer comprising a hammer rod part and two hammer head blocks detachably connected to the hammer rod part, the two hammer head blocks are respectively slidably arranged on the two fork arms, and locking parts are provided on the hammer head blocks.
[0006] The beneficial effects of this solution are as follows: through the above-mentioned arrangement, on the one hand, the hammer head block in this technical solution is slidably arranged on the fork arm, and the hammer head block can be detachably connected to the hammer rod portion. When it is necessary to perform a tendon reflex test on the patient through a percussion hammer, the hammer head block and the hammer rod portion can be connected to form a percussion hammer, which is convenient for medical staff to perform percussion detection on the patient's Achilles tendon, and the tuning fork can be struck with the hammer rod portion to make the tuning fork vibrate; on the other hand, the hammer head block is slidably sleeved on the fork arm, and a locking piece is provided on the hammer head block, which can be used to adjust the position of the hammer head block on the fork arm. The frequency of a conventional tuning fork is fixed, and the disease course or degree of sensory failure of some patients being tested is not the same, and there are differences in their vibration perception of the tuning fork detection. Through the above-mentioned arrangement, medical staff can adjust the frequency of the tuning fork by adjusting the position of the hammer head block, so that the tuning fork can be suitable for patients with different disease courses, and the patient's perception of vibrations of different frequencies can be more accurately measured, which helps to establish a correspondence between the vibration frequency and the stage of diabetic neuropathy and improve the accuracy of diagnosis. At the same time, the hammer rod portion in the present technical solution can be connected to the two hammer head blocks. When in use, the locking piece can be unlocked and the hammer rod portion can be pushed to simultaneously drive the two hammer head blocks to slide along the fork arm, so that the sliding distance of the two hammer head blocks is the same, ensuring that the counterweight is at the same height when the tuning fork is struck later, ensuring that the same frequency resonance occurs between the two fork arms, and the two hammer head blocks are linked by the hammer rod portion to slide in the same direction and at equal distances, ensuring that the mass distribution of the two fork arms is symmetrical, thereby avoiding vibration mode distortion caused by unequal distances.
[0007] This technical solution integrates tuning fork testing and tendon reflex testing functions, reducing the number of examination tools required. This solves the problem of the large variety of traditional tools, the easy omission of tools, and the inconvenience of carrying them, and improves the convenience and practicality of clinical examinations.

The overall structure is compact, and the design meets the requirements of portability while taking into account the ease of operation during the examination. Medical staff can quickly switch between percussion hammer mode and tuning fork testing mode, which is simple and efficient, reducing the tedious steps and risk of misoperation during tool replacement.
[0037] Example 2
[0038] Example 2 is basically the same Figure 4 and Figure 5 As shown, the difference between Example 2 and Example 1 is that the metal end cap 14 and the polyester end cap 13 are respectively arranged at the ends of the two fork arms 2. Through the above arrangement, the temperature sensing test can be performed while the tuning fork vibrates, and the temperature change is transmitted by vibration, which helps to further judge the patient's disease course; at the same time, the lower part of the hammer rod 5 is divided into two sections, and the two sections can be threadedly connected, and a pin 19 is set at one end for easy access at any time.
