Description

Technical Field

[0001] The present disclosure relates to the field of medical treatment devices, and more precisely, to an electric stimulation cough assistance device. Background Art

[0002] Healthy adults can produce 10 - 100 ml of secretions in the trachea every day, which contain a large number of pathogenic microorganisms and harmful substances inhaled through the airway. Humans can clear them through airway mucus ciliary movement and cough reflex to prevent airway blockage and avoid infection.

[0003] Cough is a physiological defense response aimed at eliminating secretions in the airway or foreign bodies outside the airway. Cough helps with normal mucus ciliary transport clearance and ensures airway patency.

[0004] However, when patients have diseases such as chronic obstructive pulmonary disease, asthma, and lung parenchymal injury, symptoms such as weakened ciliary mucus clearance ability in the trachea, decreased cough ability, ineffective expectoration of sputum, and impaired airway clearance ability will occur.

[0005] Currently, for patients with difficulty expectorating sputum, nurses mainly perform sputum suction manually. For patients with poor expectoration ability, and those with a large amount of sputum and sputum stasis, repeated sputum suction operations are required, and sputum suction needs to be performed multiple times a day. Besides increasing the workload and intensity of nurses, repeated sputum suction also increases the risk of adverse reactions such as airway mucosal injury and airway spasm in patients.

[0006] In addition, when patients show symptoms of sputum stasis blocking the airway, it takes some time for nurses to discover, which poses a risk of airway obstruction, hypoventilation, asphyxia, and hypoxia for patients, especially at night. If the patient's ability to cough and expectorate sputum independently recovers to a certain extent, it is not only beneficial to the recovery of lung infections but also of great significance for long-term prevention of lung infections.

[0007] Therefore, there is an urgent need for a related device to promote the patient's recovery of the ability to cough independently. Utility Model Content

[0040] The present disclosure provides an electrical stimulation cough assistance device that can assist in coughing for those with relatively weak coughing functions, and at least includes a power supply control unit, a first stimulation electrode, and a second stimulation electrode. Among them, the first stimulation electrode is electrically connected to the power supply control unit and is configured to be implanted into the organism to be stimulated, receive the first stimulation signal from the power supply control unit, and stimulate the nerves related to coughing of the organism to be stimulated by outputting an electrical stimulation signal corresponding to the first stimulation signal; the second stimulation electrode is electrically connected to the power supply control unit and is configured to be attached to the body surface of the organism to be stimulated, receive the second stimulation signal from the power supply control unit, and stimulate the muscles related to coughing of the organism to be stimulated by outputting an electrical stimulation signal corresponding to the second stimulation signal.

[0041] Before using the electrical stimulation cough assistance device of the present disclosure, operators such as doctors can implant the first stimulation electrode into a patient or other organism to be stimulated, and attach the second stimulation electrode to the body surface of the organism to be stimulated. During the use of the electrical stimulation cough assistance device of the present disclosure, the first stimulation electrode can effectively stimulate the nerves related to coughing of the organism to be stimulated to form a cough reflex, and the second stimulation electrode can effectively stimulate the muscles related to coughing of the organism to be stimulated to increase the movement strength of the muscles related to coughing of the organism to be stimulated. In this way, through the mutual cooperation of the first stimulation electrode and the second stimulation electrode, it can help the organism to be stimulated to form an effective coughing action, thereby improving the patient's coughing ability and lung function.

[0042] For the sake of easy understanding, hereinafter, with reference to Figure 1 , a specific example is combined to illustrate in detail the specific structure and working principle of the electrical stimulation cough assistance device of the present disclosure.

[0043] The present disclosure provides an electrical stimulation cough assistance device that can assist in coughing for those with relatively weak coughing functions, and at least includes a power supply control unit 1, a first stimulation electrode 2, and a second stimulation electrode 3. Among them, the first stimulation electrode 2 is electrically connected to the power supply control unit 1 and is configured to be implanted into the organism to be stimulated, receive the first stimulation signal from the power supply control unit 1, and stimulate the nerves related to coughing of the organism to be stimulated by outputting an electrical stimulation signal corresponding to the first stimulation signal; the second stimulation electrode 3 is electrically connected to the power supply control unit 1 and is configured to be attached to the body surface of the organism to be stimulated, receive the second stimulation signal from the power supply control unit 1, and stimulate the muscles related to coughing of the organism to be stimulated by outputting an electrical stimulation signal corresponding to the second stimulation signal.

[0044] Among them, it can be understood that, in order to achieve normal electrical stimulation, both the first stimulation electrode 2 and the second stimulation electrode 3 of the present disclosure are provided in pairs.

[0045] Before the use of the electrical stimulation cough assistance device of the present disclosure, an operator such as a doctor can implant the first stimulation electrode 2 into a patient or other organism to be stimulated, and attach the second stimulation electrode 3 to the body surface of the organism to be stimulated. During the use of the electrical stimulation cough assistance device of the present disclosure, the first stimulation electrode 2 can effectively stimulate the cough-related nerves of the organism to be stimulated to form a cough reflex, and the second stimulation electrode 3 can effectively stimulate the cough-related muscles of the organism to be stimulated to increase the action force of the cough-related muscles of the organism to be stimulated. In this way, through the cooperation of the first stimulation electrode 2 and the second stimulation electrode 3, it can help the organism to be stimulated to form an effective cough action, thereby improving the patient's cough ability and lung function.

[0046] Specifically, the cough-related nerves may include, but are not limited to, the T9 and T11 parts of the thoracic spinal nerves in the spinal nerves, and the L1 part of the lumbar spinal nerves. The cough-related muscles mainly include the pectoralis major, diaphragm, and abdominal muscles. Of course, there are many nerves and muscles involved in the cough action, not limited to the parts mentioned above.

[0047] In multiple clinical experiments, by implanting the first stimulation electrode 2 at the T9, T11, and L1 of the patient's spinal nerves and attaching the second stimulation electrode 3 to the pectoralis major, diaphragm, and abdominal muscles of the patient, the electrical stimulation cough assistance device of the present disclosure can effectively increase the patient's maximum airway pressure and peak expiratory flow rate, and promote the recovery of the patient's cough ability.

[0048] Furthermore, during the recovery of the patient's cough ability, the secretion volume of the respiratory tract secretions of the patient can be effectively reduced, which can not only reduce the incidence of respiratory tract infections, but also reduce the demand for nursing staff and improve the patient's quality of life.

[0049] Specifically, in an embodiment of the present disclosure, the power supply control unit 1 is configured to adjust the electrical stimulation pulse width, electrical stimulation frequency, and electrical stimulation intensity of the first stimulation electrode 2 and the second stimulation electrode 3. By adjusting the electrical stimulation pulse width, electrical stimulation frequency, and electrical stimulation intensity of the first stimulation electrode 2 and the second stimulation electrode 3, the power supply control unit 1 can effectively control the amplitude of the electrical stimulation of the user.

[0050] Specifically, a wider electrical stimulation pulse width can produce a stronger stimulation effect, while a narrower pulse width of the electroacupuncture stimulation can better simulate human physiological activities.

[0051] For patients with a relatively weak cough reflex function, at least one of the electrical stimulation pulse width, electrical stimulation frequency, and electrical stimulation intensity of the first stimulation electrode 2 can be increased to stimulate the patient to form a stronger cough reflex. For patients with a relatively good recovery of the cough reflex function, at least one of the electrical stimulation pulse width, electrical stimulation frequency, and electrical stimulation intensity of the first stimulation electrode 2 can be decreased to reduce the nerve stimulation to the patient, thereby promoting the patient to gradually form an autonomous cough reflex.

[0052] For patients with relatively weak cough-related muscle function, at least one of the electrical stimulation pulse width, electrical stimulation frequency, and electrical stimulation intensity of the second stimulation electrode 3 can be increased to stimulate the patient to form a stronger cough action. For patients with relatively good cough action function, at least one of the electrical stimulation pulse width, electrical stimulation frequency, and electrical stimulation intensity of the second stimulation electrode 3 can be decreased to reduce the muscle stimulation to the patient, thereby promoting the patient to gradually form an autonomous cough action.

[0053] For patients with both relatively weak cough reflex function and cough-related muscle function, at least one of the electrical stimulation pulse width, electrical stimulation frequency, and electrical stimulation intensity of the first stimulation electrode 2 and the second stimulation electrode 3 can be increased simultaneously to stimulate the patient to form a stronger cough reflex and cough action.

[0054] As Figure 1 shown, the electrical stimulation cough assistance device of the present disclosure can also be provided with a display area and control buttons for a doctor to operate and control the electrical stimulation cough assistance device of the present disclosure, such as inputting relevant electrical stimulation parameters, etc.

[0055] Furthermore, in an embodiment of the present disclosure, the electrical stimulation cough assistance device further includes a cough action detection device. The cough action detection device is signal-connected to the power supply control unit 1. The cough action detection device is configured to detect the cough frequency and / or cough amplitude of the organism to be stimulated. The power supply control unit 1 is configured to send a corresponding first stimulation signal to the first stimulation electrode 2 or a corresponding second stimulation signal to the second stimulation electrode 3 based on the cough frequency and / or cough amplitude of the organism to be stimulated.

[0056] Since the cough action detection device can detect the cough frequency and / or cough amplitude of the organism to be stimulated, in this way, during the operation of the electrical stimulation cough assistance device of the present disclosure, based on the cough frequency and / or cough amplitude of the organism to be stimulated, a corresponding first stimulation signal is sent to the first stimulation electrode 2 or a corresponding second stimulation signal is sent to the second stimulation electrode 3, so that the electrical stimulation pulse width, electrical stimulation frequency, and electrical stimulation intensity of the first stimulation electrode 2 and / or the second stimulation electrode 3 can be automatically adjusted according to the patient's cough frequency and / or cough amplitude without manual intervention by the doctor, thereby making the use of the electrical stimulation cough assistance device of the present disclosure more convenient.

[0057] Further, in an embodiment of the present disclosure, the power supply control unit 1 is configured to control the first stimulating electrode 2 and the second stimulating electrode 3 to perform electrical stimulation on the biological to be stimulated separately or simultaneously. That is, for a patient who can form a complete autonomous cough reflex but has weak cough-related muscle function, when applying the electrical stimulation cough assistance device of the present disclosure, the power supply control unit 1 can perform electrical stimulation on the patient only with the second stimulating electrode 3, and the first stimulating electrode 2 does not work. Similarly, for a patient who has no obstacle in the cough action but has a weak cough reflex function, when applying the electrical stimulation cough assistance device of the present disclosure, the power supply control unit 1 can perform electrical stimulation on the patient only with the first stimulating electrode 2, and the second stimulating electrode 3 does not work, which can further improve the adaptability of the electrical stimulation cough assistance device of the present disclosure to the patient.

[0058] Specifically, in an embodiment of the present disclosure, the first stimulating electrode 2 includes at least one electrode piece 21, a wire, and an insulating layer. The electrode piece 21 is disposed on the surface of the electrode piece 21 and is configured to output an electrical stimulation signal to stimulate the cough-related nerves of the biological to be stimulated; the wire is configured to be wrapped and disposed on the inner side surface of the insulating layer and is electrically connected to the electrode piece 21.

[0059] In this way, during the working process of the electrical stimulation cough assistance device of the present disclosure, the power supply control unit 1 supplies power to the first stimulating electrode 2. Since the electrode piece 21 outputs an electrical stimulation signal to stimulate the cough-related nerves of the biological to be stimulated, the electrical stimulation of the cough-related nerves of the patient can be completed. Moreover, since the wire is wrapped and disposed on the inner side surface of the insulating layer and is electrically connected to the electrode piece 21, the wire can not only supply power to the electrode piece 21 but also prevent leakage, ensuring that only the nerves corresponding to the position of the electrode piece 21 are electrically stimulated, and the nerves at other positions are not electrically stimulated, so as to ensure that the electrical stimulation cough assistance device of the present disclosure can work properly.

[0060] Further, in an embodiment of the present disclosure, the first stimulating electrode 2 includes at least two electrode pieces 21, and each electrode piece 21 is configured to be disposed along the extending direction of the wire to stimulate at least two parts of the cough-related nerves of the biological to be stimulated. Specifically, as described above, three electrode pieces 21 can be provided on the first stimulating electrode 2, so that the three electrode pieces 21 can respectively stimulate the T9 and T11 parts of the thoracic spinal nerves and the L1 part of the lumbar spinal nerves in the spinal nerves. For the T9 and T11 parts of the thoracic spinal nerves and the L1 part of the lumbar spinal nerves in the spinal nerves, multiple first stimulating electrodes 2 are respectively provided, so as to eliminate the need to lead out multiple first stimulating electrodes 2, reduce the required number of the first stimulating electrodes 2, not only make the implantation of the first stimulating electrode 2 more convenient, but also make the structure of the electrical stimulation cough assistance device of the present disclosure simpler and more convenient to use.

[0061] Specifically, in an embodiment of the present disclosure, both the electrode sheet 21 and the insulating layer are constructed of biocompatible materials. In this way, when the first stimulating electrode 2 is implanted into a patient's body, it can adapt to the patient's body, cause no significant or serious adverse reactions to the body, and the patient's body will not cause a change in the performance of the first stimulating electrode 2, thereby extending the service life of the first stimulating electrode 2.

[0062] As Figure 1 shown, in an embodiment of the present disclosure, the second stimulating electrode 3 includes an electrode patch 31, a wire, and an insulating layer. The electrode patch 31 is disposed at the end of the insulating layer and is configured to fit against the body surface of the biological to be stimulated; the wire is configured to be wrapped and disposed on the inner side of the insulating layer and is electrically connected to the electrode patch 31.

[0063] In this way, during the operation of the cough assistance device with electrical stimulation of the present disclosure, the power supply control unit 1 supplies power to the second stimulating electrode 3. Since the electrode patch 31 outputs an electrical stimulation signal to stimulate the cough-related muscles of the biological to be stimulated, the electrical stimulation of the cough-related muscles of the patient can be completed. Moreover, since the wire is wrapped and disposed on the inner side of the insulating layer and is electrically connected to the electrode patch 31, the wire can supply power to the electrode patch 31 and will not leak electricity, and it can also ensure that the second stimulating electrode 3 of the present disclosure will not generate a leakage situation, ensuring the use safety of the cough assistance device with electrical stimulation of the present disclosure.

[0064] Further, in an embodiment of the present disclosure, the cough assistance device with electrical stimulation of the present disclosure further includes a fixing part. The electrode patches 31 of each second stimulating electrode 3 are configured to be disposed on the fixing part, and the fixing part is configured to fit the body surface contour of the biological to be stimulated by its own deformation. In this way, it can be ensured that the electrode patch 31 can closely adhere to the surface of the cough-related muscles of the patient, thereby facilitating the second stimulating electrode 3 of the present disclosure to provide an electrical stimulation signal to the cough-related muscles of the patient, preventing the situation that the second stimulating electrode 3 cannot work properly due to the electrode patch 31 not being closely attached to the surface of the cough-related muscles of the patient, and ensuring the normal operation of the second stimulating electrode 3.

[0065] Specifically, in an embodiment of the present disclosure, the cough assistance device with electrical stimulation includes two fixing parts. One fixing part is configured to fit the chest or abdomen of the biological to be stimulated by its own deformation, and the other fixing part is configured to fit the abdomen of the biological to be stimulated by its own deformation. In this way, it can be ensured that one fixing part fits the corresponding positions of the pectoralis major muscle and the diaphragm of the biological to be stimulated by its own deformation, and the other fixing part fits the relative position of the abdominal muscle of the biological to be stimulated by its own deformation, thereby facilitating the cough assistance device with electrical stimulation of the present disclosure to provide an electrical stimulation signal to the pectoralis major muscle, diaphragm, and abdominal muscle of the patient, and further promoting the patient to form corresponding coughing actions.

[0066] The embodiments of the present disclosure have been described above. The above description is exemplary, not exhaustive, and is not limited to the disclosed embodiments. Many modifications and variations will be apparent to those of ordinary skill in the art without departing from the scope and spirit of the described embodiments.
