Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of auscultation equipment, and particularly relates to a wearable closed bronchiolitis auscultation detector. BACKGROUND

[0002] Bronchiolitis obliterans (BO) is a rare and fatal irreversible obstructive lung disease in pediatrics, which is a clinical syndrome caused by inflammation and fibrosis changes after small airway damage, and is mainly characterized by repeated or persistent wheezing, shortness of breath and cough, poor exercise tolerance, wheezing and moist rales can be heard in lung auscultation. In clinical diagnosis and treatment, it mainly relies on chest imaging and lung function examination. The lung function shows that the ventilation function is limited, the chest imaging shows that the lung is over-inflated, the blood vessel texture is thin, and the ground glass changes, and there may be diffuse nodular or reticular nodular shadows without infiltration shadows. Among them, the high-resolution CT of the chest has characteristic changes, which can show direct and indirect signs.

[0003] However, in the prior art, lung function and high-resolution chest CT examination are difficult to achieve real-time monitoring due to technical limitations and radiation problems. At present, an auscultation detector can be used for auscultation, but the overall monitoring effect and means are lacking, and there is a lack of airway airflow sound system capturing means, which cannot completely obtain the respiratory frequency related low frequency breath sound, wheezing high frequency wheezing sound, different obstruction degree characteristic sound and cough signal, resulting in missing of basic detection data, inability to exclude wheezing and obstruction through abnormal respiratory frequency, and inability to judge the disease condition according to the wheezing time and obstruction sound characteristics. It is easy to misjudge and miss, and it is difficult to determine the disease condition. At the same time, children patients are active and the body size is small. When the line is too long, there is no suitable bundling way to regularize the excess line, and it is easy to appear the situation that the line is entangled with the child's limbs and clothes. Children are lively and active, and the entangled line not only seriously affects their normal activities and restricts their freedom of action, but also may cause interference to the contact between the detection electrode or sensor and the skin due to the line pulling when the child moves greatly, and even may wound the child, which has a great safety hazard. When the line is too short, there is no flexible extension or adjustment structure, which will limit the placement position of the detection equipment, forcing the child to maintain a specific and possibly uncomfortable posture. This not only brings great inconvenience to the child, but also easily interferes with the detection process and affects the accuracy of the detection result.

[0004] And, due to the significant limitations in the current diagnosis of BO disease, how to use the wearable part that fits the human torso, and the connected detection circuit and related sensing, processing components, the wearable part can assist in fixing the device on the corresponding part of the body, ensuring the stability of the detection, and the connected detection circuit is used for signal transmission. The line of such a detector is usually a hard or lack of effective contraction mechanism wire without a special collection structure. If a vest type design is adopted, although there is a certain advantage in the overall wearability, it can make the detection device more stably fit the body, but it has the defect of high price, which makes many patient families difficult to bear, limiting its wide application.

[0022] The display controller 14 can be worn on the arm of an adult to facilitate observation of the response of the detector 2, and the display controller 14 is designed without physical keys, and has four functions to control the detector 2.

[0023] Mode switching key: single key switching design, used for switching between the rale collection mode and the cough sound collection mode, the back panel indicator light is switched synchronously after being pressed (blue corresponds to the rale mode, and orange corresponds to the cough sound mode), and the detector 2 automatically adjusts the sensitivity of the sound collector 4 after switching, to adapt to the collection requirements of different signals (the rale signal is weak, the sensitivity is automatically improved, the cough sound signal is relatively strong, and the sensitivity is moderately reduced to avoid overload).

[0024] Recording control key: when manual triggering recording is needed, the pause is pressed again, and the recording content is confirmed to be valid after the pause, the save key is clicked to complete saving, and the backlight flashes three times to prompt the successful saving, to facilitate subsequent playback and analysis.

[0025] Parameter adjustment key: including volume + / - key and collection intensity key, which can adjust the prompt sound volume of the detector 2, and the collection intensity key has three gears (weak, medium and strong), and the corresponding indicator light is lit when the gears are switched, the weak gear is suitable for collecting subtle rale in a quiet environment, and the strong gear is suitable for capturing cough sound in a noisy environment, to ensure the collection accuracy in different scenes.

[0026] Emergency pause key: independent red key, which can immediately pause all collection work of the detector 2 after being pressed for three seconds, to adapt to sudden situations (such as children's resistance and equipment displacement), and to ensure the safety of use.

[0027] Specifically, the sound collector 4 is provided with four medical-grade silicone detachable probes, which are soft and non-irritating when contacting the skin, to avoid resistance of children due to unsuitable probe material, and the multiple sound collectors 4 work synchronously to realize full-area auscultation of the lungs, accurately capture abnormal respiratory signals of different parts, quickly locate the corresponding lung lesion area of panting, and provide more comprehensive data support for disease diagnosis. The storage device 5 is internally provided with a Bluetooth unit 13, which can communicate with the Bluetooth unit 13 of the detector 2 in real time, and transmit the information of the sound collector 4 to the detection unit 21. The detection unit 21 includes a positioning unit, a noise reduction unit and an identification unit, and the three sub-units of the detection unit 21 work cooperatively to improve the collection accuracy and identification efficiency of the abnormal signals of the bronchioles, to avoid the problems of noise interference and missed or mistaken judgment. When the splicing sleeve 8 is not located at the set position, the two sides thereof can slide freely along the track of the slot shell 7, at this time, the storage device 5 can automatically adjust the winding length according to the stretching requirement of the connecting line 6, to adapt to the limb displacement of children during activities, to avoid breakage or too short binding activities due to excessive pulling of the line. When the splicing sleeve 8 slides to the set position, the storage device 5 is linked with the adjusting piece 9 at this time, and the length of the connecting line 6 is adjusted through the adjusting piece 9, to ensure that the sound collector 4 can be attached to the skin, and the children will not be uncomfortable due to the tightness of the line.

[0028] It can be understood that the sound collector 4 mainly detects the respiratory frequency, wheezing time and respiratory obstruction, wherein the respiratory frequency is the time for a person to breathe normally once in three to five seconds, that is, the respiratory frequency of the human body is twelve to twenty-four times per minute, if the respiratory frequency is higher or lower than the normal range, it is abnormal respiratory frequency, and then the sound collector 4 is used to record and detect the respiratory frequency, and the wheezing mainly shows chest tightness, shortness of breath, rapid breathing, subjective feeling of breathing difficulty or breathing difficulty, and the typical feature is that high-pitched whistling sound or wheezing sound appears during breathing, especially obvious during exhalation, accompanied by coughing, in addition, the respiratory obstruction mainly shows the respiratory ratio, the number of coughing, and the severity of respiratory obstruction, thereby producing different sounds.

[0029] Therefore, the sound collector 4 is used to distinguish and record the sound, thereby effectively detecting the closed bronchiolitis by auscultation, and the sound collector 4 signal capture, three of which surround the airway airflow sound, form a signal chain, first capture low-frequency breathing sound to calculate respiratory frequency, abnormality is the starting point of investigation, when airway spasm, capture high-frequency wheezing sound to record wheezing time, when obstruction is aggravated, judge the obstruction degree according to the sound intensity and frequency change (light: low-frequency friction sound, medium: medium-frequency wheezing sound, heavy: high-frequency whistle sound), and also capture coughing signal, in the analysis linkage, the three data mutually verify: when normal, the three are harmonious, early stage is slightly abnormal, and the disease progresses synchronously, and when severe obstruction, the frequency or decreases, but the wheezing is prolonged and the sound is abnormal, avoiding misjudgment of a single indicator, and the results verify that cross-validation reduces misdiagnosis: only high frequency or only wheezing sound, mostly not the disease, three abnormal and superimposed, only then judge as the disease related, and combined with the respiratory ratio.

[0030] With reference to Figures 2-6 The receiver 5 includes a rotator 51 rotatably connected inside the slot shell 7, four spaced-apart spacers 52 fixedly connected outside the rotator 51, and a silk shaft 53 fixedly connected to the bottom of the rotator 51. One end of the connecting line 6 is connected between the two spacers 52.

[0031] Specifically, in the receiver 5, two adjacent spacers 52 form an independent line receiving groove, and the inner wall of the receiving groove is covered with a layer of medical-grade silicone pad. The surface of the silicone pad has anti-slip lines, which can enhance the adhesion with the connecting line 6 and avoid the line from sliding randomly in the groove. Each receiving groove is also provided with a micro-limiting protrusion at the bottom. The protrusion is made of silicone material, which is soft and elastic. When the connecting line 6 is retracted to the shortest state, the terminal will contact the limiting protrusion. The limiting protrusion forms a buffer for the connecting line 6 through its own elasticity, avoiding hard collision between the terminal and the bottom of the receiving groove, which may cause damage.

[0032] With reference to Figures 1-7The adjusting part 9 comprises a disc 91 rotatably connected to the support rod 10, a torsion spring 92 connected between the support rod 10 and the disc 91, two arc-shaped blocks 93 provided above the disc 91 and fixedly connected to the disc 91, the two arc-shaped blocks 93 are symmetric about the center of the disc 91, and the torsion spring 92 has a low elastic coefficient and can be stretched at will.

[0033] The rotator 51 is divided into clockwise and counterclockwise rotation, the clockwise rotation of the rotator 51 is to bundle the connecting line 6, and the counterclockwise rotation of the rotator 51 is to release the connecting line 6; when the splicing sleeve 8 reaches the set position, the splicing sleeve 8 is combined with the adjusting part 9 at this time, and the splicing sleeve 8 loses the limitation of the slot shell 7, and then when the connecting line 6 is pulled, the connecting line 6 pulls the rotator 51 to rotate counterclockwise, the rotator 51 rotates counterclockwise, and since the splicing sleeve 8 loses the limitation of the slot shell 7, the splicing sleeve 8 rotates synchronously with the rotator 51, and then the splicing sleeve 8 rotates the disc 91, and when the disc 91 rotates, the torsion spring 92 elastically deforms with the rotation of the disc 91 to store elastic potential energy, and the connecting line 6 is released; when the connecting line 6 is no longer stretched, the torsion spring 92 releases the elastic potential energy to automatically reset the disc 91 to the initial position, the splicing sleeve 8 and the rotator 51 are reset synchronously, the connecting line 6 is bundled, the length of the connecting line 6 is adjusted, the stability of the line length is ensured, and on the other hand, manual control is not required.

[0034] With reference to Figures 2-6 The inside of the detector 2 is provided with a reminding unit 22, the reminding unit 22 is coupled with the detecting unit 21, four hole shafts 201 are arranged on the detector 2, two limiting blocks 202 are fixedly connected to the detector 2 close to the disc 91, the two limiting blocks 202 are symmetric about the center of the disc 91, and the limiting block 202 is attached to the top surface of the disc 91.

[0035] When the identification unit of the detecting unit 21 finds that the respiratory rate exceeds the normal range, the coughing intensity suddenly increases, the wheezing sound lasts for too long, and other abnormal symptoms, the triggering signal is immediately sent to the reminding unit 22, and the reminding unit 22 starts the corresponding reminding according to the abnormal level; when the abnormality is slight, only the green LED indicator light is lit, and flashes every three seconds to avoid disturbing children; when the abnormality is moderate, the green indicator light turns yellow and cooperates with the vibration motor to remind the parents to pay attention; when the abnormality is severe, the yellow indicator light switches to red, and the buzzer emits intermittent low-volume prompt sound, the volume is controlled within 50 decibels to avoid stimulating children and ensure that the parents or medical staff can quickly detect; in addition, the hole shaft 201 provides a guiding and protective channel for the connecting line 6, and when the connecting line 6 is stretched out of the storage slot of the storage device 5, it will first pass through the corresponding hole shaft 201 and then be connected to the sound collector 4.

[0036] With reference toFigures 2-8 The bottom of the slot shell 7 is fixedly connected with two straight rods 71, which are symmetrically arranged about the central axis of the slot shell 7. Four support shafts 72 are fixedly connected to the slot shell 7, and the outer part of the support shaft 72 is sleeved with a rotating wheel 701. Four connecting lines 6 are attached to the corresponding rotating wheels 701.

[0037] Specifically, two straight rods 71 are fixedly connected to the inner side of the bottom of the slot shell 7, which are symmetrically distributed about the central axis of the slot shell 7 and perpendicular to the bottom of the slot shell 7. The straight rod 71 provides guidance for the sliding of the splicing sleeve 8. When the rotator 51 rotates, the straight rod 71 restricts the splicing sleeve 8 from rotating, and the splicing sleeve 8 is driven by the wire shaft 53 to move up and down by the principle of the rolling shaft, ensuring that the splicing sleeve 8 can slide accurately to the set position, realizing stable linkage with the adjusting part 9. The rotating wheel 701 is made of medical-grade wear-resistant plastic, and a micro bearing is arranged between the inner wall and the support shaft 72 to ensure that the rotating wheel 701 can rotate flexibly around the support shaft 72 without obvious jamming during rotation, thereby optimizing the collection and release path of the connecting line 6, reducing line wear, and ensuring that the connecting line 6 always moves along the fixed path during collection or release, avoiding line deviation and winding due to pulling.

[0038] Referring to Figures 2-7 The splicing sleeve 8 includes a sleeve ring 81 sleeved outside the wire shaft 53, two sleeve blocks 82 fixedly connected outside the sleeve ring 81, and the sleeve block 82 is slidably sleeved outside the straight rod 71.

[0039] When the torsional spring 92 is not deformed, the distance between the arc-shaped block 93 and the limiting block 202 is equal to the width of the arc-shaped block 93, the sleeve block 82 is located between the limiting block 202 and the arc-shaped block 93, and the bottom surface of the straight rod 71 coincides with the top surface of the arc-shaped block 93.

[0040] Specifically, the sleeve ring 81 is a ring structure, the inner diameter is matched with the outer diameter of the wire shaft 53, can be closely sleeved outside the wire shaft 53, and can freely slide along the axial direction of the wire shaft 53. The outer side wall of the sleeve ring 81 is fixedly connected with two sleeve blocks 82, the two sleeve blocks 82 are symmetrically distributed about the central axis of the sleeve ring 81, and correspond to the two straight rods 71 at the bottom of the slot shell 7. A through hole matched with the straight rod 71 is formed at the central position of each sleeve block 82. When the splicing sleeve 8 needs to be moved, the wire shaft 53 is rotated, so that the sleeve block 82 slides along the axial direction of the straight rod 71. When the rotator 51 drives the wire shaft 53 to rotate clockwise, the wire shaft 53 will generate a rotating driving force on the sleeve ring 81 through threaded transmission. If the sleeve ring 81 is limited outside, it will rotate synchronously with the wire shaft 53, which will cause the sleeve ring 81 to move up and down along the wire shaft 53, and finally separate from the stable cooperation with the straight rod 71. The position cooperation between the limiting block 202 and the sleeve block 82 can directly constrain the clockwise rotation of the sleeve ring 81. When the sleeve ring 81 has a clockwise rotation trend, the sleeve block 82 will be in contact with the side wall of the limiting block 202. The limiting block 202 blocks the rotation of the sleeve block 82 through its own fixed structure, thereby limiting the rotation of the sleeve ring 81. Under the constraint of the limiting block 202, the sleeve ring 81 cannot rotate with the rotator 51, but only can convert the rotating driving force of the wire shaft 53 into the upward movement along the axial direction of the wire shaft 53. When the sleeve ring 81 moves upward to the position where the sleeve block 82 cooperates with the upper part of the straight rod 71 again, the straight rod 71 will limit the sleeve block 82 again, limit the sleeve ring 81 from continuing to move upward or deviate, and make the sleeve ring 81 return to the stable state, so that the splicing sleeve 8 always cooperates with the wire shaft 53 and the straight rod 71 stably, realizes the accuracy and safety of the length adjustment of the connecting line 6, and effectively maintains the stable operation of the internal structure of the equipment.

[0041] With reference to Figures 1-9 , the outer parts of the rotator 51 and the spacer 52 are attached to the inside of the slot shell 7, and the outer parts of the rotator 51 and the spacer 52 are high-friction treated with the inside of the slot shell 7. Specifically, a sandblasting process can be used to form rough textures on the contact surfaces, or a medical-grade rubber coating with a high friction coefficient can be sprayed, to avoid accidental rotation due to equipment vibration or slight touching by children, and to ensure that the length of the connecting line 6 remains stable.

[0042] With reference to Figures 1-9 , the central line of the first guide wheel 11 coincides with the hole shaft 201, the outer diameter of the second guide wheel 12 is tangent to the central line of the first guide wheel 11, the second guide wheel 12 is located between the first guide wheel 11 and the receiver 5, and the surfaces of the first guide wheel 11 and the second guide wheel 12 are made of smooth and wear-resistant polyurethane material. The connecting line 6 can reduce the friction between the line and the components through the rotation of the guide wheels, can be limited, and can correspond to the hole shaft 201, so that the connecting line 6 can be smoothly contracted and stretched, and can always move along a fixed track when the line is contracted and stretched.

[0043] The working principle of the present application is as follows: in use, first, the detector 2 is fixed on the corresponding lung area of the user's torso through the elastic and breathable bandage 1, the bandage 1 can be flexibly adjusted according to the body size to ensure that the detector 2 is attached but not restricted in movement, and the four sound collectors 4 are respectively attached to the corresponding areas of the upper and lower lobes of the lungs, when the four sound collectors 4 are stretched, the connecting line 6 is pulled, the tension is transmitted to the rotator 51 through the connecting line 6, the rotator 51 rotates counterclockwise to release the line, at this time the sleeve ring 81 is not located at the set position, the sleeve block 82 can slide freely along the straight rod 71, the sleeve ring 81 cannot rotate synchronously with the rotator 51, at this time, the rotator 51 rotates to drive the connecting line 6 to be released from the storage groove, the connecting line 6 stretches along the track of the rotating wheel 701, the first guide wheel 11 and the second guide wheel 12, and is adapted to the displacement of the sound collector 4 through the hole shaft 201 to avoid excessive pulling and breaking of the line, when the movable sleeve ring 81 slides along the wire shaft 53 to the set position, the sleeve block 82 is connected with the arc block 93 at this time, the spliced sleeve 8 and the adjusting piece 9 form linkage, and the slotless shell 7 is forced to limit, when the connecting line 6 is stretched, the rotator 51 rotates counterclockwise, the sleeve ring 81 rotates to extrude the arc block 93, the disc 91 rotates, and the torsional spring 92 rotates with the disc 91 to produce elastic deformation, at this time the connecting line 6 is released, and when the connecting line 6 loses the stretching force, the torsional spring 92 makes the disc 91 and the sleeve ring 81 rotate back, the sleeve ring 81 drives the wire shaft 53 to rotate clockwise, and then drives the rotator 51 to wind the connecting line 6 clockwise, the excess line is wound into the storage groove of the partition 52, and the fine adjustment of the connecting line 6 is realized, when it is needed to completely shrink the connecting line 6, at this time the rotator 51 is rotated to drive the wire shaft 53 to rotate clockwise, the sleeve block 82 is in contact with the side wall of the limiting block 202, the limiting block 202 restricts the clockwise rotation of the sleeve ring 81, the wire shaft 53 drives the sleeve ring 81 upward through threaded transmission, the limiting block 202 blocks the rotation of the sleeve block 82, so that the sleeve ring 81 only moves up and down along the axial direction of the wire shaft 53, recombines with the upper segment of the straight rod 71, and keeps the structure stable.
