Description

Technical Field

[0001] The utility model belongs to the field of diaphragm pacemakers, in particular to a portable external diaphragm pacemaker. Background Art

[0002] Diaphragm pacing is to improve ventilation by causing diaphragm contraction through functional electrical stimulation of the phrenic nerve. There are two types of diaphragm pacemakers: implantable diaphragm pacemakers and external diaphragm pacemakers. The former is traumatic and can lead to many iatrogenic complications, including damage to the phrenic nerve during electrode implantation surgery, local tissue infection, and scar compression of the nerve, which are difficult for patients to accept. It is also expensive and not suitable for rehabilitation treatment.

[0003] External diaphragm pacemakers are mainly used for lung rehabilitation therapy in clinical practice. For example, in the stable stage of chronic obstructive pulmonary disease, the patient's chest tightness, shortness of breath and lung inflammation have improved, but the lung function needs to recover slowly. Therefore, external diaphragm pacemakers can be used to perform lung rehabilitation therapy, which is helpful for the recovery of lung function. For some patients with chronic respiratory failure, long-term chest tightness and asthma symptoms make the lung function poor, and the diaphragm is also in a state of excessive fatigue. At this time, diaphragm pacemakers can also be used for rehabilitation auxiliary treatment, which is beneficial to improve lung function. For some patients with respiratory failure caused by myasthenia gravis, central nervous system damage, etc., external diaphragm pacemakers can replace the nerves that innervate the diaphragm, which is crucial to improving respiratory failure. In terms of working principle, the external diaphragm pacemaker outputs electrical pulses, which act on the patient through lead wires and electrodes, thereby stimulating the phrenic nerve, causing the diaphragm to contract, and achieving the purpose of compulsory diaphragm exercise. Although the technical principles are relatively mature, in terms of specific usage functions, conventional external diaphragm pacemakers currently generally rely on manual attachment of electrodes and are unable to achieve automated operation. Moreover, this manual attachment mode is not ideal in terms of positioning accuracy, operational consistency, and efficiency. Utility Model Content
