Description

Digital percussion instrument based on resonance measurement

[0001] The present invention relates to a digital percussion device based on resonance measurement, and more particularly, to a digital percussion device based on resonance measurement having an improved structure that enables the implementation of a digital technology that standardizes and digitizes the diagnosis results by organically combining a driving device capable of applying force to determine whether there is an abnormal state of air or liquid in the chest or abdomen, the degree of enlargement of internal organs, etc., and a complex sensor technology capable of precisely detecting the rebound value due to the force.

[0002] A physical examination is an essential procedure in clinical medicine, primarily for identifying symptoms and subsequently conducting necessary diagnosis and treatment. This examination can narrow down the range of diseases that may be causing the symptoms, and the results can lead to appropriate treatment. Furthermore, the results of these tests can be used to make decisions about testing, taking into account factors such as cost, accuracy, and potential risks to the patient, ensuring an accurate diagnosis. Therefore, the physical examination is considered a crucial tool in clinical medicine.

[0003] The physical examination is conducted in the following order: visual inspection, palpation, percussion, and auscultation. Before a detailed diagnosis, the clinician quickly examines the patient to determine whether there are any current health problems or diseases, and collects physiological data after the initial diagnosis or determines whether a detailed diagnosis is necessary.

[0004] Percussion is a diagnostic method that involves placing one finger under the abdomen or chest and tapping it with another finger or other percussion instrument. It is used to diagnose the affected area by checking the sound or vibration produced when tapping the affected area or by the patient's response.

[0005] It diagnoses whether the tissue under the body surface is solid or contains air or liquid by checking its density through sound or vibration. In the case of a chest assessment, it diagnoses pneumothorax, emphysema, collapsed lung, pleural effusion, empyema, lung tumor, and other diseases, or diagnoses the movement of the chest due to breathing. In the case of an abdominal assessment, it diagnoses at an early stage whether an organ is enlarged or whether there is ascites, and whether there is pathology in the tissue through the sound it makes when vibrating.

[0006] Since percussion is diagnosed based on the doctor's senses and experience, such as differences in the force of the tap, the sound produced, and differences in judgment of the response, the results of percussion are determined by the subjective judgment of the medical staff, which can lead to errors in the initial diagnosis, which can lead to misdiagnosis regarding the need for a more precise diagnosis later.

[0007] For this reason, the number of times percussion is performed is gradually decreasing, and the number of medical professionals who can perform it accurately is also decreasing. However, percussion can still be used to make an early diagnosis by differentiating tension pneumothorax, cardiac tamponade, emphysema, and pleural effusion in thoracic diseases, and is also used to differentiate ovarian tumors and the presence of ascites. In addition, imaging tests (CT, MRI, X-ray, ultrasound, etc.), which are used as an alternative method to percussion, have fatal drawbacks in that they are expensive and many primary and secondary medical institutions other than large medical institutions have difficulty obtaining the relevant imaging diagnostic equipment, making them unusable. In addition, the time required for test results is also a significant problem.

[0010] The existing diagnosis method using percussion involves the medical staff tapping the affected area with a hammer-shaped percussion instrument or their fingers to determine the sound or vibration. Therefore, it is difficult to accurately distinguish between vibratory sounds and resonant sounds (acoustic sounds, dull sounds, etc.), which leads to errors in the accuracy of the diagnosis results. In addition, the results vary depending on the experience and skill of each doctor. In addition, it is difficult to distinguish between the various reactions of patients, which leads to difficulties in the initial diagnosis.

[0011] The present invention has been devised to solve the above problems, and the purpose of the present invention is to provide a digital percussion device based on resonance measurement that can accurately identify and diagnose the patient's condition information by organically combining a driving device capable of applying force to determine whether there is an abnormal condition of air or liquid in the chest or abdomen, the degree of enlargement of internal organs, etc., with a complex sensor technology capable of precisely detecting the rebound value due to the force, and standardizing and digitizing the examination results.

[0015] It is preferable that the present invention further include a pair of contact guides protruding from the case body on both sides of the case body centered on the housing portion, so that the tip comes into contact with the contact.

[0016] It is preferable that a battery for supplying power is built into the interior of the case body, and that a charging port for charging the battery is provided on one side of the case body.

[0027] As illustrated in FIGS. 1 to 4, a digital percussion device based on resonance measurement according to an embodiment of the present invention is intended to determine the state of internal organs through resonance generated by striking a body surface (a), and comprises a case body (1), a percussion member (2), and a resonance measurement sensor (3).

[0028] The above case body (1) is manufactured in a portable size, and has a printed circuit board (not shown) built in with circuit components for digital measurement of resonance sound according to the force intensity or the reverberation after the force, and a display panel (12) for displaying the numerical values ​​according to the digital measurement and a plurality of operation buttons (11) including a power button are installed so that they can be exposed to the outside.

[0029] Here, since the printed circuit board is an essential component for controlling the digital percussion device based on resonance measurement according to the present embodiment, the printed circuit board and the cable that electrically connects the printed circuit board and various electronic components are collectively referred to as a control device.

[0030] The above operation button (11) may be a button that performs various functions, such as a power button for applying an On / Off input signal to the control device, a striking button for applying an input signal for operating the striking member (2) so that the body surface (a) can be struck using the striking member (2).

[0031] The above-mentioned striking member (2) is installed relative to the case body (1) so as to be movable, and is inserted into the inside of the case body (1) and protrudes outward, and plays a role in striking the body by protruding outward from the case body (1).

[0032] These percussion members (2) can be configured to be dynamically connected to an actuator implemented in various ways, such as a solenoid or pneumatic device, and to move relative to the case body (1) according to the operation of the actuator.
