Description

ICU is with breathing exercise and termination supraventricular tachyarrhythmia dual function's device

Technical Field

The utility model relates to the technical field of medical equipment, concretely relates to ICU is with breathing exercise and termination room upper velocity arrhythmia dual function's device.

Background

Patients after large-scale thoracotomy are often monitored by ICU, the patients face the need of early respiratory function exercise after the operation, and the incidence rate of ventricular tachyarrhythmia is about 13-34% after the operation or acute attack of chronic obstructive pulmonary disease, which causes the patients to enter the ICU rarely. The breathing exercise device on the market at present only has single inspiration and expiration function training, inspiration and expiration muscle strength exercise and positive end expiratory pressure PEEP function for preventing alveoli from collapsing, and a device for stopping the supraventricular tachycardias by utilizing the principle of Valsalva action of stimulating the vagus nerve is not yet on the market. The Valsalva action is a clinical physiological test which makes a patient tightly close the glottis after deeply inhaling, uses force to do exhalation action, resists the tightly closed epiglottis during exhalation, and influences the blood circulation and autonomic nerve function state by increasing the intrathoracic pressure so as to achieve the purpose of diagnosis and treatment. The REVERT study published by "LANCET" (LANCET) 8.2015 proposed a method called Modified Valsalva Maneuver (MVMT) that was very effective from the results: the supraventricular tachycardial attack can be terminated by allowing the patient to blow for 15 seconds in a semi-reclining or sitting position with a 10ml syringe (about 40mmHg pressure). Thus, existing respiratory exercise devices fail to meet both the need for early respiratory function exercise and the risk of avoiding a concurrent supraventricular tachyarrhythmia episode.

The use of functional training techniques is effective in clinical rehabilitation, which generally actively seeks to minimize the conflict between breathing and movement by instructing the patient to exercise the respiratory motion synchronization using a respiratory exercise device so that the action of the inspiratory and expiratory muscles is consistent with the extension and flexion movements of the torso. The Valsalva action is a clinical physiological test that the patient tightly closes the glottis after deeply inhaling, then forcibly exhales, resists the tightly closed epiglottis during exhalation, influences the blood circulation and autonomic nerve function state by increasing the intrathoracic pressure, and further stops the supraventricular tachyventricular attack. The REVERT study published by LANCET in 2015 proposed a method called Modified Valsalva Manoeuvre Technique (MVMT) which was very effective from the results: the supraventricular tachycardial attack can be terminated by allowing the patient to blow for 15 seconds in a semi-reclining or sitting position with a 10ml syringe (about 40mmHg pressure).
