Description

Technical Field

[0001] The invention belongs to the technical field of expectoration, and in particular relates to a wearable expectoration machine and a method for using the same. Background Art

[0002] Wearable expectorant is a new type of medical device, mainly used to help patients expel sputum from the respiratory tract. Wearable expectorants usually use physical vibration. It generates vibrations of a specific frequency and intensity, which are transmitted to the patient's chest or back to loosen the sputum and make it easier to cough up. This vibration can stimulate the respiratory mucosa and promote ciliary movement, thereby improving the efficiency of sputum discharge.

[0003] Existing vibration expectoration devices mainly include percussion expectoration machines and expectoration vests, which are all trolley-type devices with large size. During the treatment, the patient sits or lies down and cannot move, which will lead to poor treatment effect. Summary of the invention

[0004] The purpose of the present invention is to provide a wearable sputum removal machine and a method of using the same in order to solve the above-mentioned inconvenience in use.

[0005] The technical solution adopted by the present invention is as follows: a wearable sputum removal machine includes a main unit, a back panel is provided on one side of the main unit, a back panel buffer foam is provided at one end of the back panel relative to the main unit, a connecting belt is provided at one end of the back panel buffer foam, a front panel is provided on one side of the connecting belt, and a front panel buffer foam is provided on one side of the front panel.

[0006] By adopting the above technical solution, the two-layer structure of the vibration vest works together to transmit vibration to the patient's chest or back, loosen the sputum through vibration of a specific frequency, and promote sputum discharge. At the same time, the design of the vest can ensure that the vibration is evenly distributed and improve the expectoration effect. The main function of the connecting belt is to fix the vibration vest on the patient to ensure that the device does not slip or shift during use. Compared with traditional treatment methods, the wearable vibration expectoration machine can be completely worn on the patient, and the patient can move freely and unconstrained during treatment. This innovative treatment device brings a new treatment experience to patients. Traditional expectoration methods often require patients to lie in bed for a long time, connected to bulky medical equipment, and extremely inconvenient to move. Not only are patients prone to depression and anxiety, but they may also cause muscle atrophy and poor blood circulation due to long-term lack of activity. The wearable vibration expectoration machine breaks this bondage. Patients can move freely in the ward, communicate and interact with their families, and even go outdoors accompanied by medical staff to breathe fresh air and enjoy the warmth of the sun. This ability to move freely helps patients maintain a positive attitude and enhance their confidence in recovery.

[0007] In a preferred embodiment, an atomization interface base is provided on one side of the host, an atomization air inlet interface is provided on one side of the atomization interface base, an atomization air nozzle is provided on the upper end of the atomization air inlet interface, and a blood oxygen sensor cable connector is provided on one side of the host. The atomizer structure composed of these components can ensure that the device can simultaneously realize the functions of atomization, pulse rate monitoring, active breathing guidance, and vibration expectoration.

[0008] By adopting the above technical solution, the atomization interface base plays the role of connecting various components to ensure the structural stability of the entire device. The atomization air inlet interface is used to connect the atomizer mask, so that the patient can perform atomization treatment while expectorating. The atomization air nozzle can output compressed air and connect the trachea to the inside of the atomizer. Atomization therapy can convert drugs into tiny particles, which directly act on the lungs through the respiratory tract, playing an anti-inflammatory, antitussive, and expectorant role. The blood oxygen probe cable connector can be connected to a specific drug delivery device to deliver the drug directly to the patient's respiratory tract.

[0009] In a preferred embodiment, a controller is disposed on one side of the front panel, a controller touch display screen is disposed on an upper surface of one side of the controller, and a controller data connection line is disposed on the upper surface of the controller.

[0010] By adopting the above technical solution, the active breathing animation effect is displayed on the display screen during the vibration treatment process to guide the patient to inhale and exhale, and combined with the vibration, a better treatment effect is achieved.

[0011] In a preferred embodiment, a plurality of vibration disk bottom shells are provided on one side of the back plate and the front plate, a foam cushion is provided at the lower end of the vibration disk bottom shell, a lower shock-absorbing plate is provided on the upper surface of the foam cushion, a driving coil is provided at the upper end of the lower shock-absorbing plate, a permanent magnet vibrator is provided at one end of the driving coil relative to the lower shock-absorbing plate, an upper shock-absorbing plate is provided at one end of the permanent magnet vibrator relative to the driving coil, and a vibration disk upper shell is provided at one end of the upper shock-absorbing plate relative to the permanent magnet vibrator.

[0012] By adopting the above technical solution, the wearable vibrating expectorant is based on the principle of high-frequency chest wall oscillation. Through the directional percussion of 8 vibrating discs distributed around the front, back, left, right, and top and bottom areas of the chest cavity, high-frequency oscillations of a certain frequency and amplitude are generated and act on the chest wall, so that the mucus and metabolites on the surface of the respiratory tract are loosened and liquefied. The change in gas flow rate in the airway caused by the oscillation can produce a certain intensity of shear force, prompting the secretions to detach from the tracheal wall; in addition, the oscillation can also promote the swing of airway cilia and promote the discharge of sputum. A single vibrating disc is composed of a driving coil, a permanent magnet vibrator, upper and lower shock-absorbing plates, an upper vibrating disc bottom shell, and a soft pad. The driving coil, the permanent magnet vibrator, and the upper and lower shock-absorbing plates are the core vibration structures of the vibrating disc. The main control board generates an alternating current signal of a certain frequency into the driving coil, generating a magnetic field to drive the permanent magnet vibrator to reciprocate in the forward and reverse directions, generating a vibration force, which acts on the human chest wall after being buffered by the soft pad. Compared with the pneumatic pulse oscillation expectoration machine which can only oscillate as a whole, the 8 vibration plates of this product can work at the same time, acting on the entire chest cavity, or can be enabled individually to avoid the patient's stomach and heart and other organ areas, reducing the stimulation of the important organs of weak patients. Compared with the vibration percussion expectoration machine, this product can act on the entire chest cavity at the same time, without the need for medical staff to hold the percussion head and move the treatment on the patient's body surface, reducing the working time of medical staff and optimizing the work process and efficiency. Compared with traditional treatment methods, the wearable vibration expectoration machine can be completely worn on the patient, and the patient can move freely and unconstrained during treatment; and the vibration is combined with coughing and expectoration. All expectoration machines require the patient to cough to complete the sputum discharge. The work process of traditional equipment is to vibrate continuously. When the patient wants to cough, press the emergency stop button, the equipment stops vibrating, the patient coughs and expectorates, and the equipment works passively. However, this device will guide the patient to actively do a quick exhalation action every time it vibrates for a period of time to improve the efficiency of expectoration.

[0013] In a preferred embodiment, a plurality of shock absorbers are disposed on the upper surface of the main machine.

[0014] By adopting the above technical solution, the shock absorber is used to connect the various components of the sputum removal machine. The shock absorber is used to connect the back plate and the back plate buffer foam to reduce the impact of vibration on the circuit components.

[0015] In a preferred embodiment, an atomizing pump is disposed inside the main unit.

[0016] By adopting the above technical solution, the atomizer pump converts the medicine into tiny particles and then delivers the medicine to the patient's respiratory tract through the atomizer mask. The atomizer pump block plays the role of fixing and protecting the atomizer pump.

[0017] A wearable sputum removal machine and a method of using the same, comprising the following steps:

[0018] a. Open the chest buckle of the vibration vest, put it on the patient, and then fasten the chest buckle; adjust the tightness of the shoulder straps and waist belt so that the 8 vibration plates can be tightly attached to the appropriate position of the chest cavity without affecting normal breathing; if you need to use the pulse rate monitoring function, you need to connect the blood oxygen probe to the main control module through the adapter cable; if you need to use the atomization function, you need to connect the atomization mask to the atomization connection hose.

[0019] b. During the vibration treatment, the active breathing animation effect is displayed on the screen to guide the patient to inhale and exhale, and combined with vibration to achieve better treatment effect.

[0020] c. Combination of vibration and coughing for expectoration. The expectoration machine requires the patient to cough to expel sputum. The traditional working process is that the device vibrates continuously. When the patient wants to cough, he presses the emergency stop button. After the device stops vibrating, the patient coughs to expectorate. The device is in passive working mode. This device adopts active working mode. After each vibration for a period of time, it will guide the patient to actively exhale quickly to improve the efficiency of expectoration.

[0021] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0022] 1. In the present invention, the two-layer structure of the vibration vest works together to transmit vibration to the patient's chest or back, loosen the sputum through the vibration of a specific frequency, and promote the discharge of sputum. At the same time, the design of the vest can ensure that the vibration is evenly distributed and improve the expectoration effect. The main function of the connecting belt is to fix the vibration vest on the patient to ensure that the equipment will not slip or shift during use. Compared with traditional treatment methods, the wearable vibration expectoration machine can be completely worn on the patient, and the patient can move freely and unconstrained during treatment. This innovative treatment device brings a new treatment experience to patients. Traditional expectoration methods often require patients to lie in bed for a long time, connected to bulky medical equipment, and extremely inconvenient to move. Not only are patients prone to depression and anxiety, but they may also cause muscle atrophy and poor blood circulation due to long-term lack of activity. The wearable vibration expectoration machine breaks this bondage. Patients can move freely in the ward, communicate and interact with their families, and even go outdoors accompanied by medical staff to breathe fresh air and enjoy the warmth of the sun. This ability to move freely helps patients maintain a positive attitude and enhance their confidence in recovery.

[0023] 2. In the present invention, the animation effect of active breathing is displayed on the display screen during the vibration treatment process to guide the patient to inhale and exhale, and combined with vibration to achieve better treatment effects. Specifically, in the "automatic mode" and "manual mode" interfaces, there is an active cycle breathing dynamic diagram display, in which the progress bar moves to prompt the patient's vital capacity, and the words in the figure are prompts. The patient should make breathing adjustments, deep inhalation, breath holding, deep exhalation, rapid inhalation and rapid exhalation according to the prompts and the progress bar status to cooperate with the vibration of the sputum removal machine. The dynamic progress bar in the middle of the screen indicates the lung volume, and the progress bar expands to the right to indicate that the patient inhales and increases the lung capacity; the progress bar contracts to the left to indicate that the patient exhales and reduces the lung capacity. The speed of the progress bar changes indicates the speed of breathing, and it is displayed in different colors during the breathing adjustment, deep breathing and rapid exhalation stages. Atomization, high-frequency chest wall oscillation and active breathing cycle are combined to achieve a full-process design of softening, shedding, gathering and discharge of sputum. During the vibration therapy process, an active breathing animation effect is displayed on the screen to guide the patient to inhale and exhale, which combined with vibration can achieve better treatment effects.

[0024] 3. In the present invention, the wearable vibrating expectorant is based on the principle of high-frequency chest wall oscillation. Through the directional percussion of 8 vibrating discs distributed around the front, back, left, right, and top and bottom areas of the chest cavity, high-frequency oscillations of a certain frequency and amplitude are generated and act on the chest wall, so that the mucus and metabolites on the surface of the respiratory tract are loosened and liquefied. The change in gas flow rate in the airway caused by the oscillation can produce a certain intensity of shear force, prompting the secretions to detach from the tracheal wall; in addition, the oscillation can also promote the swing of airway cilia and promote the discharge of sputum. A single vibrating disc is composed of a driving coil, a permanent magnet vibrator, upper and lower shock-absorbing plates, an upper vibrating disc bottom shell, and a soft pad. The driving coil, the permanent magnet vibrator, and the upper and lower shock-absorbing plates are the core vibration structures of the vibrating disc. The main control board generates an alternating current signal of a certain frequency that enters the driving coil, generates a magnetic field to drive the permanent magnet vibrator to reciprocate in the forward and reverse directions, generates a vibration force, and acts on the human chest wall after being buffered by the soft pad. Compared with the pneumatic pulse oscillation expectoration machine which can only oscillate as a whole, the 8 vibration plates of this product can work simultaneously, acting on the entire chest cavity, or can be enabled individually to avoid the patient's stomach, heart and other organ areas, reducing the stimulation of important organs of weak patients. Compared with the vibration percussion expectoration machine, this product can act on the entire chest cavity at the same time, without the need for medical staff to hold the percussion head and move it on the patient's body surface for treatment, reducing the working time of medical staff and optimizing the workflow and efficiency. Compared with traditional treatment methods, the wearable vibration expectoration machine can be completely worn on the patient, and the patient can move freely and unconstrained during treatment; and the vibration is combined with coughing and expectoration. And this device will guide the patient to actively do a quick exhalation action every time it vibrates for a period of time, improving the efficiency of expectoration.

The speed of the progress bar change indicates the speed of breathing. It is displayed in different colors during the breathing adjustment, deep breathing and rapid exhalation stages. Atomization, high-frequency chest wall oscillation and active breathing cycle are combined to realize the full process design of sputum softening, shedding, collection and discharge; during the vibration treatment, the animation effect of active breathing is displayed on the display screen to guide the patient to inhale and exhale.

8. A wearable sputum removal device as claimed in claim 1, characterized in that: The overall structure of this product is a vest, with 8 vibrators distributed in multiple directions of the chest. The vibration of each area can be switched on and off through a controller, and directional tapping can be performed through 8 vibration plates distributed around the front, back, left, right, and top and bottom areas of the chest.

9. A method for using a wearable sputum removal machine as described in claims 1 to 9, characterized in that: The following steps are involved: a. Open the chest buckle of the vibration vest, put it on the patient, and then fasten the chest buckle; adjust the tightness of the shoulder straps and waist belt so that the 8 vibration plates can be tightly attached to the appropriate position of the chest cavity without affecting normal breathing; if you need to use the pulse rate monitoring function, you need to connect the blood oxygen probe to the main control module through the adapter cable; if you need to use the atomization function, you need to connect the atomization mask to the atomization connection hose; b. During the vibration treatment, the active breathing animation effect is displayed on the display screen to guide the patient to inhale and exhale, and combined with the vibration, to achieve better treatment effects; c. Combination of vibration and coughing for expectoration. All expectoration machines require the patient to cough to complete the expectoration. The working process of traditional equipment is continuous vibration. When the patient wants to cough, he presses the emergency stop button, the equipment stops vibrating, and the patient coughs to expectorate. The equipment works passively. In this device, every vibration for a period of time will guide the patient to actively make a quick exhalation action, thereby improving the efficiency of expectoration.
