Description

Technical Field

[0001] The utility model relates to the field of medical instruments, in particular to a vibration pen. Background Art

[0002] At present, the vibration sense tool used for foot screening of diabetic patients is commonly a tuning fork, such as the 128Hz tuning fork commonly seen on the market. As a vibration sense examination medical tool for screening diabetic foot lesions, it consists of a metal cylindrical contact and a metal U-shaped body. At the beginning of the examination, moderate force is applied by manual strong tapping to stimulate the metal structure to produce vibration. Then, the medical staff gently touches the patient's foot with the front cylindrical contact of the tuning fork to transmit the vibration to the sole of the foot. This moment is crucial, and then the medical staff will guide the patient to autonomously perceive the vibration of the sole of the foot. Through the professional guidance of the medical staff, the patient is helped to accurately judge the feeling, so as to evaluate the vibration sensitivity of the sole of the foot. The purpose of the whole process is to detect whether the patient has neuropathy, that is, whether the nerve function is impaired. By using the vibration sensing of the tuning fork, medical staff can obtain important information about the patient's sole nerve response. This early detection of sensory loss helps to take timely treatment measures, thereby reducing the risk of complications that patients may face. Therefore, in the process of medical diagnosis and treatment, the screening and diagnosis of diabetic foot has always been an important and complex link.

[0003] Although the traditional tuning fork tool has basic detection functions, it still has some shortcomings in practical applications. First, the manual tapping of the tuning fork is easily affected by the difference in strength of medical staff, resulting in inconsistent test results. For the goal of pursuing precision medical testing, it has a great impact. Secondly, the fixed frequency characteristics of the traditional tuning fork make it lack the function of adjustable frequency conversion, and cannot meet the personalized needs of different individuals for vibration sensation evaluation. In fact, there may be large differences in vibration sensation thresholds among different groups of people, and the fixed frequency tuning fork cannot achieve refined detection, which in turn affects the accuracy of the test results. Furthermore, the vibration source of the traditional tuning fork comes from the manual operation of medical staff. This means that the skill level and fatigue level of medical staff may affect the vibration intensity, further reducing the accuracy and reliability of the test. In the current situation where both doctors and patients are under pressure, this factor should be paid more attention. Utility Model Content

The following description of the preferred embodiments may involve combinations of features, which may exist independently or in combination, and the present invention is not particularly limited to the preferred embodiments. The scope of the present invention is defined by the claims.

[0050] like Figure 1-Figure 10 As shown, the vibrating pen of the embodiment of the utility model comprises a housing, a battery 3, a main control board 4 and a vibrating device, the housing comprises an upper housing 1, a lower housing 2 and a cavity formed by the buckling connection between the upper housing 1 and the lower housing 2, the battery 3 is electrically connected to the vibrating device through the main control board 4, and the three are all arranged in the cavity;

[0056] In addition, the vibration pen of the present application can also be configured with a related information transmission module, which can transmit the test data to related equipment or platforms in real time to realize real-time data analysis, which is beneficial for medical staff to analyze, record and share test data and test results, and help improve the quality and efficiency of diagnosis and treatment.

[0057] It should be noted that, in the present invention, the end of each component close to the vibration contact 6 is the top end, and the other opposite end is the bottom end.

[0058] In some embodiments of the present utility model, the display assembly 8 is directly opposite to the upper housing 1 and includes an LED 8 character display screen and a plurality of status indicator lights;

[0059] The upper shell 1 is made of a translucent light-transmitting plate, or

[0060] A transparent window corresponding to the position of the display assembly 8 is provided on the upper housing 1 .

[0062] It can be understood that the use of LED 8-character display screen to display the vibration frequency has the advantages of low cost and easy installation. Other forms of display screens, such as TN broken code screens, can also be used.

[0063] The upper shell 1 is made of a translucent plate, and the light of the LED can pass through the translucent plate for medical staff to view. Of course, a transparent window can also be directly provided to achieve this function.

[0064] In some embodiments of the present invention, the upper shell 1 and the lower shell 2 are connected by snapping or gluing, or by snapping and gluing, which can further improve the assembly stability. The upper shell 1 and the lower shell 2 are buckled to form a plurality of mounting grooves that match the shapes of the battery 3, the main control board 4 and the vibration device;

[0065] The lower shell 2 is semi-cylindrical, and the side of the upper shell 1 away from the lower shell 2 is a first plane structure 101 parallel to the display assembly 8. During use, medical staff can place their thumbs on the first plane structure 101, which is convenient for medical staff to hold and use, and to exert force, making medical staff more comfortable during the vibration examination.

[0066] The first planar structure 101 may cover the entire upper shell 1 from the top to the bottom, or may cover a portion of the upper shell 1 from the top to the middle.

[0067] In some embodiments of the present invention, the vibration contact 6 includes a columnar portion and a clamping portion disposed at the bottom of the columnar portion, and the clamping portion includes two symmetrically disposed clamping protrusions 602;

[0068] The columnar portion includes two second planar structures 601 parallel to the display assembly 8 .

[0069] In some embodiments of the present invention, a shock absorbing pad 10 is further included at the top of the cavity, and the output rod of the motor 5 passes through the shock absorbing pad 10 and is connected to the vibration contact 6 .

[0070] A connection groove is provided from the clamping part to the columnar part of the vibration contact 6, and the output rod passes through the shock-absorbing pad 10 and is placed in the connection groove, so that the motor 5 drives the vibration contact 6 to vibrate. When the motor 5 vibrates, it drives the output rod to vibrate, and transmits it to the vibration contact 6 to complete the entire vibration process. The main function of the shock-absorbing pad 10 is to reduce the vibration from the vibration head to the hand, ensuring that medical staff will not experience numbness in their hands due to long-term vibration during operation.

[0071] Typically, the shock-absorbing pad 10 is made of rubber, and the vibration contact 6 is made of hard plastic, and the surface of the columnar part of the vibration contact 6 is smooth and the edges are rounded to avoid scratching the patient's skin.

Since the two clamping protrusions 602 are symmetrically arranged, the positions of the first strip groove 1003 and the second strip groove 1004 are also symmetrical.

[0075] In some embodiments of the present invention, a charging interface 9 is further provided on the housing, and the charging interface 9 is electrically connected to the battery 3 through the main control board 4 .

[0076] Among them, the charging interface 9 can be set to two-point charging, or it can use a traditional PCBA or TYPE-C interface for charging.

[0077] The present invention is described in detail below with reference to specific embodiments.

[0078] Example 1

[0079] like Figures 1 to 3 As shown, a vibration device, a battery 3, a main control board 4 and a frequency adjustment component are arranged in sequence from the top to the bottom of the cavity. The frequency adjustment component is a rotary adjustment component, including:

[0080] A rotary potentiometer 11 fixedly disposed at the bottom end of the cavity is electrically connected to the main control board 4;

[0081] The rotary button 12 located outside the housing is fixedly connected to the rotating handle of the rotary potentiometer 11 , and the rotary button 12 is connected to the power switch 7 via a plastic plug 13 .

[0082] The upper shell 1 and the lower shell 2 are fixed by snap-fitting, and the power switch 7 is fixed by using a plastic plug 13 and a rotary button 12 to fix the power switch 7 and the rotary button 12. The rotary potentiometer 11 is welded to the main control board 4, and the main control board 4 is fixed to the lower shell 2 by screws, and the mainboard pins are welded to the main control board 4.

[0083] Example 2

[0084] like Figures 4 to 6 As shown, the fixing method of each component and the connection method between components in Example 2 are the same as those in Example 1, but the difference is that: the vibration device, the main control board 4, the frequency adjustment component and the battery 3 are arranged in sequence from the top to the bottom of the cavity, and the frequency adjustment component is a rotary adjustment component, including:

[0085] A rotary potentiometer 11 fixedly arranged in the middle of the cavity is located above the main control board 4, and the rotary potentiometer 11 is electrically connected to the main control board 4;

[0086] The rotary button 12 located on the upper housing 1 is fixedly connected to the rotating handle of the rotary potentiometer 11 .

[0087] In addition, in the second embodiment, the power switch 7 and the frequency adjustment component are separately arranged. To improve the space utilization, the display component 8 is arranged directly above the motor 5. The display component 8 is electrically connected to the electric control board through a vertical wiring method. The rotary potentiometer 11 is arranged near the top of the main control board 4, and the power switch 7 is arranged near the bottom of the main control board 4. The rotary button 12 is arranged on one side of the first planar structure 101, and the power switch 7 is arranged on the side of the housing.

[0088] Example 3

[0089] like Figures 7 to 9 As shown, the fixing method of each component and the connection method between components in Example 3 are the same as those in Example 1, and the positional relationship is the same as that in Example 2, but the difference is that: the vibration device, the main control board 4, the frequency adjustment component and the battery 3 are arranged in sequence from the top to the bottom of the cavity, and the frequency adjustment component is a push-type adjustment component, including:

[0090] Two push-type potentiometers 14 are fixedly arranged in the middle of the cavity, and are located above the main control board 4. The two push-type potentiometers 14 are electrically connected to the main control board 4.

[0091] The two frequency adjustment buttons 15 located on the upper housing 1 are fixedly connected to the buttons of the two push-type potentiometers 14 respectively.

[0092] The use principle of the vibration pen of the embodiment of the utility model is: first, long press the power switch 7 to turn on the pen, the motor 5 is energized to vibrate, and then the vibration contact 6 starts to vibrate.

[0093] Under the condition of using a rotary adjustment component (such as Example 1 and Example 2), when frequency modulation is required, if the frequency needs to be increased, the switch knob is twisted clockwise, thereby driving the potentiometer rotary knob of the rotary potentiometer 11 to rotate clockwise. At this time, the clockwise rotation of the rotary button 12 controls the current passing into the motor 5 through the rotary potentiometer 11 and the main control board 4, changes the vibration frequency of the motor 57, and completes the frequency adjustment. Conversely, when the frequency needs to be reduced, it can be rotated counterclockwise.

[0094] Under the condition of using a push-type adjustment component (such as Example 3), when frequency modulation is required, pressing the frequency modulation button 15 close to the side of the vibration contact 6 once can slowly increase the frequency, such as increasing the frequency by 1Hz each time it is pressed. When the frequency modulation button 15 is long pressed, the frequency can be quickly increased. The frequency modulation button 15 away from the side of the vibration contact 6 has the function of reducing the frequency, which also includes two methods: tapping and long pressing.

[0095] When it is necessary to switch to the frequency of 128 Hz, press the power switch 7 once.

[0096] The utility model has at least the following two advantages:

[0097] ① The utility model realizes the function of accurate frequency setting at 128Hz, which solves the problem of unequal frequency and amplitude caused by different force and uneven position when tuning forks are used manually. The utility model mainly uses ultrasonic motor drive, and changes the current and voltage output by the battery to change the rotation frequency of the motor, thereby changing the vibration frequency of the entire product. Since the main factors for changing the frequency are the voltage and current, this product can achieve accurate control of the vibration frequency.

[0098] ② The utility model realizes the function of accurate frequency modulation within a predetermined range (such as 0-350Hz), which solves the problem that the tuning fork can only provide fixed frequency vibration and optimizes the scientific research environment in the field of diabetic foot screening in the future. This advantage is that by rotating the rotary button or pressing the frequency modulation button (long press or tap), the frequency modulation signal is transmitted to the main control board, and the main control board changes the current and voltage of the power supply battery, thereby controlling the rotation frequency of the ultrasonic motor and ultimately changing the vibration frequency.

[0099] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
