Description

Technical Field

[0001] The present specification relates to the field of medical device technology, and in particular to an intelligent respiratory system infection secretion discharge device. Background Art

[0002] Increased airway secretions in the human body can lead to airway obstruction, increased breathing work, fatigue of respiratory muscles, and finally respiratory failure. By externally tapping and vibrating the patient's chest, the lungs can be vibrated. This vibration is transmitted to the airway, which can cause the airway secretions to vibrate, thereby increasing the fluidity of the airway secretions. The flowing secretions can stimulate the airway mucosa and cause the patient to cough, which can discharge the secretions. Based on the above principle, the extracorporeal vibrating expectoration machine generates vibrations in the oscillation head and applies them to the patient's back, promoting the patient's expectoration through the force of vibration and tapping.

[0003] At present, the sputum removal devices used in clinical practice mainly rely on mechanical vibration to promote the discharge of sputum from the patient's lungs. The single mechanical vibration method has limited effect in some cases, especially when dealing with sputum with high viscosity. Therefore, the development of smarter and more flexible sputum removal devices has important clinical significance. Summary of the invention

[0004] In order to solve the problems in the related art, the present disclosure provides an intelligent respiratory infection secretion discharge device, which has greater flexibility and intelligence and can effectively improve the expectoration effect.

[0005] The intelligent respiratory system infection secretion discharge device includes: a host, a connection base and an oscillating head, and also includes a sound wave generator, wherein:

[0006] The host comprises a servo motor for generating mechanical vibration and a voltage generator for driving the sound wave generator;

[0007] An electrical interface is provided in the connection base, the electrical interface is connected to the voltage generator via an electrical conductor, and the connection base is used to connect the oscillation head;

[0008] There is a cavity at the center of the oscillation head, and the sound wave generator is arranged in the cavity;

[0009] After the oscillation head is connected to the connection base, the sound wave generator is connected to the electrical interface and generates sound wave vibration under the voltage drive of the voltage generator, and the oscillation head generates mechanical vibration under the power drive of the servo motor.

[0010] The intelligent respiratory infection secretion discharge device provided by the present invention utilizes sonic vibration and mechanical vibration to assist in expectoration. Through the improved design of the main unit, transmission components and oscillation components, the oscillation head in direct contact with the patient can output sonic vibration and mechanical vibration, and can be adaptively and intelligently adjusted according to the human body condition. The technical solution of the present invention can significantly improve the expectoration effect, provide convenience for the operator, and has a wider range of application scenarios.

[0029] In this specification, it should be understood that terms such as "including" or "having" are intended to indicate the presence of features, numbers, steps, behaviors, components, parts or a combination thereof disclosed in this specification, and are not intended to exclude the possibility that one or more other features, numbers, steps, behaviors, components, parts or a combination thereof exist or are added.

[0030] It should also be noted that, in the absence of conflict, the embodiments and features in the embodiments in this specification may be combined with each other.

[0031] The extracorporeal vibration expectoration machine is designed based on the principle of physical directional percussion. Its treatment is through pure mechanical vibration, which produces a comprehensive therapeutic force with periodic changes in a specific direction on the human body. One type of therapeutic force is perpendicular to the body surface. The percussion and tremor it produces on the human body can relax and liquefy the mucus and metabolites on the surface of the respiratory tract, making them smaller and looser. The other type is a horizontal therapeutic force parallel to the body surface. The directional squeezing and pushing effect it produces on the human body can gradually discharge the liquefied mucus in the bronchus from the body in the squeezing and pushing direction.

[0032] When the existing sputum removal machine is working, the servo motor in the main unit generates mechanical vibration, which then provides power to the connecting component through the transmission component, driving the oscillating head at the terminal to generate squeezing and vibrating forces. There is an eccentric wheel mechanism inside the connecting component, which allows the oscillating head to be eccentrically connected to the transmission flexible shaft. By transferring the force through the connecting elbow, the oscillating head will generate radial amplitude when vibrating. For example, the common eccentricity is 3.5mm, and the oscillating head will have a radial amplitude of 7mm when rotating. The force generated by this radial amplitude can be decomposed into horizontal and vertical components, which respectively produce pushing and slapping effects.

[0033] In this mode where only the servo motor provides power, the oscillating head can only output the above-mentioned mechanical vibration. This vibration has a relatively large force and is suitable for patients with normal physiques. For elderly and weak patients or patients whose wounds are healing after surgery, gentle vibration should be used to help expectorate, but the gentle vibration effect of existing expectoration machines is limited. On the other hand, in the process of helping patients expectorate, changes will also occur inside the patient's body. In particular, after the sputum is vibrated to relax and liquefy, effective auxiliary force should be provided to help the sputum out of the airway. Therefore, the force during the auxiliary expectoration operation should be adjusted according to the patient's physical condition and cannot be adjusted solely by the operator's experience. In particular, when the adjustment of the force requires the replacement of the oscillating head, it will increase the inconvenience of operation.

[0034] To this end, the inventors have improved the existing expectoration machine and proposed an intelligent respiratory infection secretion discharge device that utilizes acoustic vibration and mechanical vibration. The main unit, transmission components, connecting components and oscillation head have all been improved and designed so that the oscillation head that is in direct contact with the patient can output acoustic vibration and mechanical vibration, thereby improving the expectoration effect and providing convenience for the operator under the action of dual vibration.

[0035] Hereinafter, exemplary embodiments of the present disclosure will be described in detail with reference to the accompanying drawings so that those skilled in the art can easily implement them. For the sake of clarity, parts not related to the description of the exemplary embodiments are omitted in the accompanying drawings.

[0036] In the following figures, Figure 1 This is a connection status diagram of the intelligent respiratory system infection secretion discharge device provided in an embodiment of the present disclosure, Figure 2 is the structural diagram of the oscillating head. Figure 3 The internal structure diagram of the host. Figure 4 This is a schematic diagram of the connection between the elbow and the connection base. Figure 5 A schematic diagram of the structure of the connection base.

[0037] like Figure 1 As shown, the intelligent respiratory system infection secretion discharge device provided by the present disclosure includes a host 100, a connection base 200 and an oscillating head 300, and also includes a sound wave generator 400, wherein the host 100 includes a servo motor 110 for generating mechanical vibrations and a voltage generator 120 for driving the sound wave generator 400 (see Figure 3 ); The connection base 200 is provided with an electrical interface 210 (see Figure 5 ), the electrical interface 210 is connected to the voltage generator 120 through the electrical conductor 220, and the connection base 200 is used to connect the oscillation head 300; there is a cavity 310 in the center of the oscillation head 300, and the sound wave generator 400 is arranged in the cavity 310 (see Figure 2). After the oscillating head 300 is connected to the connecting base 200, the sound wave generator 400 is connected to the electrical interface 210, and generates sound wave vibration under the voltage drive of the voltage generator 120; the oscillating head 300 generates mechanical vibration under the power drive of the servo motor 110.

[0038] The oscillation head 300 is also called a "percussion head" and can be round or saddle-shaped. The round oscillation head in the drawings of the present disclosure is for illustration only. The sound wave generator 400 and the oscillation head 300 can be a separate structure, which is convenient for installation and maintenance. When the oscillation head is replaced, the sound wave generator can remain connected to the electrical interface. When it is necessary to replace the oscillation head of another shape, there is no need to replace the sound wave generator 400. This separate structure also reduces the cost of consumables (oscillation head).

[0039] The principle of using sound wave vibration to help expectoration is as follows: In the lungs of healthy people, the cilia on the bronchial wall swing up and down rhythmically, generating low-frequency vibrations of 16 to 40 Hz. This vibration dilutes the viscous secretions in the trachea and moves them upward to the laryngopharynx, and finally out of the lungs through coughing or swallowing. The intelligent respiratory infection secretion discharge device uses sound waves with the same frequency as the cilia on the bronchial wall, and transmits this sound wave through the human body to the bronchi, which can assist the human body in diluting and separating the viscous secretions and accelerate the process of sputum discharge.

[0040] During operation, according to the user setting or the setting of the automatic mode, the mechanical vibration of the oscillating head 300 can generate a squeezing, vibrating, and pushing force on the patient's back, which can vibrate and relax the secretions in the patient's airway and lung cavity and liquefy them. The acoustic vibration generated by the acoustic generator 400 is transmitted to the body through the patient's skin, resonates with the patient's lung cavity, promotes the liquefied sputum to move toward the throat, and accelerates the process of sputum discharge. Or, according to the actual situation of the patient, only acoustic vibration is used, and gentle and gentle acoustic vibration is used to assist the patient in expectoration, which not only reduces the physical risks to special patients, but also eliminates the tedious operation of the operator to replace the oscillating head, thereby improving the operating efficiency.

[0041] like Figure 1 As shown, the intelligent respiratory system infection secretion discharge device also includes an oscillation line 500, the two ends of which are respectively connected to the host 100 and the connection base 200, and the oscillation line 500 is an elastic soft shaft, and a coaxial wire passage 510 is arranged inside the oscillation line 500 (see Figure 4 The electrical conductor 220 connects the electrical interface 210 to the voltage generator 120 through the conductor path 510. The improved design of the oscillation line can effectively support the dual vibration output of the oscillation head.

[0042] like Figure 1 , 2As shown, the intelligent respiratory system infection secretion discharge device also includes a connecting elbow 600, and the two ends of the connecting elbow 600 are respectively connected to the connecting base 200, the oscillating head 300 and the sound wave generator 400. The connecting elbow 600 also has a built-in wire, and electrical interfaces are also provided at both ends, so that the sound wave generator 400 can maintain electrical connection with the connecting base 200. In one embodiment, an elbow electrode sheet 611 and an elbow electrode ring 612 are provided at one end of the connecting elbow 600 connected to the connecting base 200, and the electrical interface 210 of the connecting base 200 also has an electrode sheet 211 and an electrode ring 212 corresponding thereto. After the two are connected, the circuit is connected, as shown in FIG. Figure 4 , 5 The electrical interface may have other structures.

[0043] like Figure 3 As shown, inside the host, the servo motor 110 and the voltage generator 120 are respectively connected to the main control board 130, and an oscillation line channel is provided at the central position of the host housing, through which the oscillation line 500 is connected to the servo motor 110. The back of the host has a power socket and a data interface 150.

[0044] like Figure 5 As shown, an electrical interface 210 is provided in the center of the connection base 200, and the electrical interface 210 is composed of an electrode sheet 211 and an electrode ring 222, and is connected to two electrodes of the voltage generator 120 through an electrical conductor 220. The oscillation head 300 can also be directly connected to the connection base 200, which has a corresponding electrical interface. A gripping handle 230 is also provided on the connection base 200, and a sound wave excitation switch 240 is provided on the gripping handle 230. The sound wave excitation switch 240 is used to manually control the circuit between the sound wave generator 400 and the voltage generator 120 to connect or disconnect. The on and off state of the sound wave vibration is controlled by manual operation, which increases the flexibility of operation.

[0045] Figure 6 1 is a functional structure block diagram of the host 100 in an embodiment of the present disclosure.

[0046] like Figure 6 As shown, a main control board 130 is also provided in the host 100, and the main control board 130 is used to control the output of the servo motor 110 and the voltage generator 120 according to the body data of the executed object, and the body data includes a blood oxygen concentration value and a respiratory rate value.

[0047] Patients with respiratory diseases have increased airway secretions, which can lead to airway obstruction, increased work of breathing, and respiratory muscle fatigue. These airway manifestations can be reflected through physical data. By monitoring the body of the subject, these real-time physical data can be obtained to understand the respiratory status of the patient's lungs and airways.

[0048] Furthermore, the intelligent respiratory infection secretion discharge device also includes a data acquisition unit 140, which acquires body data of the executed object through a collection component that is in direct contact with the body of the executed object, or obtains the body data of the executed object by reading data collected by an external monitoring instrument through a data interface 150.

[0049] There are two ways to monitor the body data of the executed object. One way is to obtain the body data of the executed object through a collection component that is in direct contact with the body of the executed object. These collection components become part of the intelligent respiratory system infection secretion discharge device as a unit module. For example, a finger-clip type, patch type or wearable collection component is directly connected to the patient's body to directly obtain the patient's body data, which can monitor the patient's physical state in real time and reliably, and transmit the monitoring data to the control system. Another way is to obtain the body data of the executed object by reading the data collected by the peripheral monitoring instrument. For example, it is connected to other peripheral monitoring devices such as electrocardiogram monitors through a data interface to obtain more comprehensive body data of the patient. These two ways of monitoring body data can be used alone or in combination. After the body data is provided to the host 100, the main control board 130 performs calculations and comparisons, and controls the output accordingly.

[0050] When the patient's airway is blocked, the inhaled oxygen is significantly reduced, the blood oxygen concentration is also reduced, and the respiratory rate increases. Therefore, the patient's airway status can be understood by monitoring the patient's blood oxygen concentration and respiratory rate. On this basis, the main control board 130 can control the intensity and time of the output vibration only by using the change of the blood oxygen concentration value, or can control the intensity and time of the output vibration only by using the change of the respiratory rate value. Through experiments, it was found that using the change of blood oxygen concentration value to control the vibration intensity and using the change of respiratory rate value to control the vibration time can achieve a better effect of promoting expectoration and reduce other risks.

[0051] Furthermore, the host 100 of the intelligent respiratory system infection secretion discharge device also includes an input unit 160, which is used to receive manually input parameter settings, and the main control board 130 is also used to control the output of the servo motor 110 and the voltage generator 120 according to the parameter settings and body data. These parameter settings include parameters such as the frequency, amplitude, and action time of the mechanical vibration. This will make the output vibration both meet the operator's settings and can be adaptively adjusted according to the patient's physical condition, with greater flexibility and a wider range of applications.

[0052] Furthermore, a storage unit 170 is also provided in the host 100 for storing preset vibration output modes. The main control board 130 controls the corresponding outputs of the servo motor 110 and the pressure generator 120 according to the selected output mode. The pre-stored vibration output mode can be only sound wave vibration, only mechanical vibration and dual vibration mode. The dual vibration mode can also include a combination configuration of frequency, time and intensity suitable for different scenes. The operator can choose to output one type or two types of vibration according to the actual situation, and output through the preset mode, which reduces the complexity of operation and improves the operation efficiency.

[0053] On this basis, the intelligent respiratory infection secretion discharge device also includes a display unit 180, which is used to display the body data acquired by the data acquisition unit, as well as relevant information of the currently output sound wave vibration and mechanical vibration, including frequency, intensity, time, output mode, etc.

[0054] As an example, Figure 7 A schematic diagram of the external structure of the host in an embodiment of the present disclosure is given.

[0055] like Figure 7 As shown, there is an oscillation line channel in the center of the main housing, and the oscillation line 500 extends outward from the channel. At the axis of the oscillation line 500 is an electric wire 220 for connecting the sound wave generator 400 and the voltage generator 120. The input unit 160 is two independent knobs, and the display unit 180 is two independent display screens. Other functional units are integrated on the main control board.

[0056] According to the technical solution provided in the present invention, through the improved design of the main unit, the oscillation line and the oscillation head, it is possible to achieve dual vibration outputs of acoustic vibration and mechanical vibration. Combined with the patient's real-time physical condition, the output vibration intensity and time can be adaptively controlled, which helps to obtain a better expectoration effect.
