Description

Technical Field

[0001] The present invention relates to the field of medical instruments, and in particular to a vibration detector and a vibration detection method. Background Art

[0002] Coughing is one of the most important respiratory defense reflexes of humans. Coughing is a double-edged sword. Under normal physiological conditions, coughing helps to clear respiratory secretions and harmful factors. In a diseased state, frequent and severe coughing can cause damage to the body and cause great distress to patients. Increased cough sensitivity is the main clinical and pathophysiological feature of cough patients. Therefore, the assessment of cough sensitivity is not only conducive to exploring the pathophysiological mechanism of coughing and the development of new drugs, but also plays an important role in evaluating the patient's condition and efficacy.

[0003] The airway afferent nerves that control the cough reflex include unmyelinated C fibers and myelinated Aδ fibers. The terminal synapses of C fibers are mainly sensitive to chemical stimulation, while the terminal synapses of Aδ fibers are mainly sensitive to mechanical stimulation. The sensitivity of cough reflex can be evaluated through cough provocation test: using different cough inducers / factors to activate airway cough receptors, causing nerve impulses to induce the body's cough reflex, and by comparing the intensity of the stimulus factors or the cough response (such as dose-effect curve, etc.), the cough sensitivity can be evaluated.

[0004] At present, the cough provocation test mainly uses the chemical cough inducer inhalation stimulation method, and the most widely used stimulant is capsaicin. However, the capsaicin cough provocation test has great limitations: first, the capsaicin cough sensitivity range of normal people overlaps greatly with that of cough patients, and some patients with chronic cough have normal capsaicin cough sensitivity; in addition, after successful treatment, the capsaicin cough sensitivity of some patients with chronic cough has not decreased accordingly. It can be seen that the specificity of the cough sensitivity detection method based on chemical stimulation is not ideal. The evaluation of cough sensitivity should include the evaluation of chemical cough sensitivity and physical cough sensitivity. The capsaicin provocation test reflects the chemical cough sensitivity, but the chemical cough provocation test alone lacks the evaluation of physical cough sensitivity, which has certain limitations and cannot fully reflect the patient's cough sensitivity. Foreign scholars have tried to use tuning forks and electric shavers to conduct cough induction tests to evaluate cough sensitivity based on physical stimulation. These tests attempted to use vibration to stimulate the subjects' cervical trachea, but the above-mentioned instruments did not conform to the anatomical structure of the neck and did not take into account the differences in neck width among individual subjects. They were unable to accurately transmit vibration stimulation to the cervical trachea and would stimulate and interfere with other tissues in the neck, resulting in inaccurate test results. The instruments are difficult to use as an objective indicator for assessing physical cough sensitivity. Summary of the invention

[0005] Based on this, the present invention aims to overcome the defects of the prior art physical stimulation instruments that are not compatible with the cervical trachea and anatomical structure, cannot transmit vibration stimulation to the cervical trachea well, or may stimulate other tissues of the neck, resulting in inaccurate test results, and provides a vibration detector and a vibration detection method.

[0008] The vibration detector of this technical solution is designed according to the special anatomical structure of the tracheal ring of the neck, so that it matches the trachea and anatomical structure of the neck, and the contact surface will not be too large or too small, and will not stimulate other tissues of the neck, thereby ensuring the test results, and the tester has a high degree of comfort and a good experience. Specifically, this embodiment controls the opening and closing of the vibration component through a control component. The curved surface structure is the side that contacts the neck of the tester. The curved surface structure includes transition arc surfaces located at both ends of the vibration head, and concave arc surfaces that are smoothly connected to and circumscribed to the transition arc surfaces at both ends. The concave arc surface cooperates with the transition arc surfaces at both ends to form a groove, and the groove can better fit the trachea of ​​the neck, which not only ensures the contact surface, but also better transmits the vibration stimulation to the trachea of ​​the neck, and does not stimulate other tissues of the neck, thereby ensuring the accuracy of the test results. The transition arc surface contacts the neck skin on both sides of the tracheal ring, which is convenient for positioning the groove on the tracheal ring. At the same time, the transition arc surface reduces the discomfort of the tester and improves the user experience. Furthermore, the vibration motor of the present technical solution is arranged in the housing, that is, the vibration motor is surrounded by the vibration head and the housing, so that the vibration efficiency of the vibration motor is higher and the vibration range can be concentrated to ensure that the vibration intensity of the vibration head is not weakened.

[0009] In one of the embodiments, the vibration head is snap-connected to the shell at one side close to the shell.

[0010] In one of the embodiments, the vibration head is an elastic vibration head.

[0011] In one of the embodiments, it further comprises a vibration measuring device connected to the control component, wherein the vibration measuring device is mounted on the vibration motor.

[0016] In one embodiment, the transverse diameter of the groove formed by the concave arc surface and the transition arc surface is in the range of 2.5 cm to 5.5 cm.

[0017] In one embodiment, the longitudinal diameter of the groove formed by the concave arc surface and the transition arc surface is in the range of 2 cm to 3 cm.

[0018] This technical solution also provides a vibration detection method, the steps are as follows:

[0019] Turn on the vibration detector and adjust the vibration frequency;

[0020] Place the vibrating head close to the trachea of ​​the subject's neck and vibrate;

[0021] The vibration is timed to stop when a first preset time is reached;

[0022] Observe and record subject responses;

[0035] The “first” and “second” mentioned in the present invention do not represent specific quantities and orders, but are merely used to distinguish names.

[0036] like Figure 1-Figure 3 A vibration detector shown in the figure includes: a vibration component 10 and a control component 20 connected to the vibration component 10; the vibration component 10 includes a shell 11, a vibration motor 12 arranged in the shell 11, and a vibration head 13 connected to the shell 11, and the vibration motor 12 is connected to the control component 20; the vibration head 13 is a curved structure on the side away from the shell 11; the curved structure includes transition arc surfaces 131 located at both ends of the vibration head 13, and concave arc surfaces 132 that are smoothly connected to and circumscribed with the transition arc surfaces 131 at both ends.

[0037] The vibration detector of this embodiment is designed according to the special anatomical structure of the tracheal ring of the neck, so that it matches the trachea and anatomical structure of the neck, and the contact surface is not too large or too small. At the same time, it will not stimulate other tissues of the neck. It can transmit physical stimulation to specific parts of the neck more accurately to ensure the test results, and the test subject has a high degree of comfort and a good experience. Specifically, this embodiment controls the opening and closing of the vibration component 10 through the control component 20. The curved surface structure is the side that contacts the neck of the test subject. The curved surface structure includes transition arc surfaces 131 located at both ends of the vibration head 13, and concave arc surfaces 132 that are smoothly connected to and circumscribed with the transition arc surfaces 131 at both ends. The concave arc surface 132 cooperates with the transition arc surfaces 131 at both ends to form a groove, which can better fit the trachea in the neck, ensuring the contact surface, better transmitting the vibration stimulation to the trachea in the neck, and not stimulating other tissues in the neck, thereby ensuring the accuracy of the test results. The transition arc surface 131 contacts the neck skin on both sides of the tracheal ring, which is convenient for positioning the groove on the tracheal ring. At the same time, the transition arc surface 131 reduces the discomfort of the tester and improves the user experience. In addition, the vibration motor 12 of this embodiment is arranged in the housing 11, that is, the vibration motor 12 is surrounded by the vibration head 13 and the housing 11, so that the vibration efficiency of the vibration motor 12 is higher, and the vibration range can be concentrated to ensure that the vibration intensity of the vibration head 13 is not weakened. The vibration detector described in this embodiment produces non-invasive physical vibration stimulation to the human body, which is easier for the subjects to accept and has a higher degree of cooperation.

[0038] In this embodiment, the vibration head 13 is connected to the housing 11 by snapping. Specifically, the housing 11 is provided with two snap-ons on the side close to the vibration head 13, and the vibration head 13 is provided with two snap-ons 133 on the side close to the housing 11, and the assembly is completed by snapping the snap-ons 133 and the snap-ons. In addition, the housing 11 is provided with a clearance hole for the wire 30 to pass through, and the vibration motor 12 is connected to the control component 20 through the wire 30.

[0039] The vibration head 13 described in this embodiment is an elastic vibration head. On the one hand, the elastic vibration head makes the use more comfortable, and on the other hand, the buckle is also set as an elastic buckle, which is more conducive to the disassembly and assembly with the bayonet. The vibration head 13 described in this embodiment is a silicone vibration head, and in other embodiments it can be a rubber vibration head or other elastic vibration heads.

[0040] This embodiment not only includes a vibration motor 12 for generating vibration, but also includes a vibration measuring device (not shown in the figure) for measuring the vibration frequency and connected to the control component 20, and the vibration measuring device is installed on the vibration motor 12. Specifically, the vibration measuring device includes an electrically connected single-chip microcomputer and a six-axis acceleration sensor, the single-chip microcomputer is connected to the control component 20, and the six-axis acceleration sensor is installed on the vibration motor 12 to collect acceleration information of the vibration motor 12. The single-chip microcomputer performs spectrum conversion on the collected acceleration information, and frequency estimation can be performed through fast Fourier transform FFT. At the same time, the frequency acceleration information is divided twice to obtain vibration displacement information, so that the vibration frequency and vibration amplitude can be obtained through the control component 20.

[0041] The vibration motor 12 described in this embodiment includes a motor body and a four-switch BUCK-BOOST circuit electrically connected to the motor body. The four-switch BUCK-BOOST circuit is connected to the control component 20. The vibration intensity of the motor body varies with the input voltage. The output voltage is increased or decreased by controlling the four switches, thereby achieving adjustable vibration intensity of the motor body.

[0042] Therefore, the control component 20 described in this embodiment not only includes a switch button 21 for turning on and off the vibration motor 12, but also includes a frequency adjustment button 22 for adjusting the frequency of the vibration motor 12. In addition, a pause button 23 for temporarily stopping the vibration of the vibration motor 12 can also be provided. Specifically, the control component 20 includes a housing 25 and a controller (not shown in the figure) disposed in the housing 25, and the switch button 21, the frequency adjustment button 22 and the pause button 23 are all disposed on the outer wall of the housing 25 and are electrically connected to the controller. The intensity of the vibration stimulation can be adjusted by the frequency adjustment button 22. On the one hand, the appropriate stimulation intensity can be explored in the experiment to improve the test method; on the other hand, the responses of different subjects to different stimulation intensities can be isomorphically compared to better explore the pathogenesis of the disease.

[0043] The control assembly 20 of this embodiment further includes a battery (not shown) connected to the controller, so that it can be used without an external power supply, expanding the application area. In addition, the housing 25 is also provided with a charging socket 26 for connecting to the battery and charging the battery. The charging socket 26 is connected to an external power supply to store electricity for the battery.

[0044] In order to facilitate real-time observation of the start, stop or pause state, vibration frequency, vibration time and power of the vibration motor 12 so as to better perform the vibration test, the control component 20 described in this embodiment includes a display screen 24.

[0045] Considering the curvature of the trachea surface of the neck, in order to better fit the trachea, the angle α between the concave arc surface 132 and the common tangent of the transition arc surface 131 at both ends of the embodiment is in the range of 140°-160°. Preferably, the angle α can be selected as 150°. And for ease of manufacturing, the various specifications of the two transition arc surfaces 131 in this embodiment are the same.

[0046] Similarly, if Figure 4 As shown, considering that the transverse diameter of the trachea ranges from 1.5cm to 2.5cm, the transverse diameter A of the groove formed by the concave arc surface 132 and the transition arc surface 131 in this embodiment ranges from 2.5cm to 5.5cm. Specifically, the vibration head 13 in this embodiment can be set to three specifications, and the transverse diameter A of the groove corresponding to the three specifications ranges from 2.5cm to 3.5cm, 3.5cm to 4.5cm, and 4.5cm to 5.5cm, respectively. Therefore, according to the difference in the width of the individual neck, a vibration head of corresponding specifications can be configured to further ensure the accuracy of the test results.

[0047] like Figure 5 As shown, the length of an adult trachea is about 6.5 cm, with a total of 6-8 tracheal rings, and the thyroid gland is located between the second and fourth tracheal cartilages. Therefore, in order to avoid the thyroid gland, the longitudinal diameter B of the groove formed by the concave arc surface 132 and the transition arc surface 131 is in the range of 2 cm to 3 cm. Preferably, the longitudinal diameter B is 2.5 cm.

[0048] This embodiment also provides a vibration detection method, the steps are as follows:

[0049] Turn on the vibration detector and adjust the vibration frequency;

[0050] Place the vibrating head close to the trachea of ​​the subject's neck and vibrate;

[0051] The vibration is timed to stop when a first preset time is reached;

[0052] Observe and record subject responses;

[0053] After a second preset time, increase the vibration frequency and repeat the above inspection steps.

[0054] Specifically, before the test, the examiner locates the obvious tracheal ring above the subject's sternal fossa, turns on the vibration detector, adjusts the vibration frequency through the frequency adjustment button, and then puts the vibration head close to the trachea of ​​the subject's neck, presses the start button, and the vibration detector starts to vibrate and counts for 10 seconds. When the vibration is completed, press the pause button; during the pause period, observe and record the subject's reaction for 20 seconds, and record the number of coughs of the subject from the start of stimulation to the end and pause for a total of 30 seconds. Perform the next physical vibration stimulation at an interval of 1 minute, increase the vibration frequency through the frequency adjustment button, repeat the above inspection steps, stimulate a total of three times, and the inspection is completed.

[0055] The vibration detection method of this embodiment can obtain the response of the subject under vibration stimulation of different vibration frequencies, thereby knowing the relationship between cough sensitivity and vibration frequency, and improving the accuracy of the test.

[0056] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0057] The above-mentioned embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
