一种重症病人康复训练辅助装置及其工作方法An auxiliary device for rehabilitation training of critically ill patients and its working method

技术领域technical field

本发明创造属于病人康复训练的领域，具体涉及了一种重症病人康复训练辅助装置及其工作方法。The invention belongs to the field of rehabilitation training for patients, and specifically relates to an auxiliary device for rehabilitation training for critically ill patients and a working method thereof.

背景技术Background technique

ICU获得性衰弱(ICU acquired weakness,ICU-AW)是危重症患者常见的获得性神经肌肉功能障碍，是ICU较为严重的并发症之一。ICU-AW不仅会延长患者ICU机械通气时间和住院时间，增加医疗费用，还严重影响患者的远期生活质量。ICU acquired weakness (ICU-AW) is a common acquired neuromuscular dysfunction in critically ill patients and one of the more serious complications of ICU. ICU-AW will not only prolong the duration of ICU mechanical ventilation and hospital stay, increase medical expenses, but also seriously affect the long-term quality of life of patients.

CU-AW的特征是对称性的四肢无力，肢体近端肌肉(如肩部和髋部)受累较远端更为显著，而面部肌和眼外肌较少累及，还会累及呼吸机，多发生于机械通气患者。临床表现为脱机困难、轻瘫或四肢瘫、反射减少和肌萎缩。CU-AW is characterized by symmetrical weakness of the limbs. The proximal muscles of the limbs (such as the shoulder and hip) are more significantly involved than the distal muscles, while the facial muscles and extraocular muscles are less involved, and the ventilator is also involved. Occurs in mechanically ventilated patients. Clinical manifestations include difficulty weaning, paresis or quadriplegia, decreased reflexes, and muscle atrophy.

目前临床上采取早期活动进行干预的研究较多，有学者认为患者一入ICU应当进行早期的功能锻炼和物理治疗。尽管已有开展ICU机械通气患者早期活动的专家共识，但是临床实践效果欠佳，德国的一项一日现况调查发现仅有24％的机械通气患者及8％的气管插管患者将早期下床活动作为常规护理项目。国内ICU也普遍存在行机械通气时对患者采取制动和镇静，只有转出ICU后才开始物理治疗的问题，大大增加了ICU-AW的发病风险。At present, there are many clinical studies on early mobilization for intervention. Some scholars believe that patients should receive early functional exercise and physical therapy as soon as they enter the ICU. Although there is an expert consensus on early mobilization of mechanically ventilated patients in the ICU, clinical practice is not effective. A one-day status survey in Germany found that only 24% of mechanically ventilated patients and 8% of intubated patients were mobilized early. Bed activities as routine care items. It is also common in domestic ICUs to immobilize and sedate patients during mechanical ventilation, and to start physical therapy only after being transferred out of the ICU, which greatly increases the risk of ICU-AW.

所以目前急需一种可以解决IUC病人难以脱机问题的装置。Therefore, there is an urgent need for a device that can solve the problem that IUC patients are difficult to wean.

随着电刺激的进行，肌肉会渐渐发生疲劳，所以需要对肌肉电压误差值进行分析，确认这个误差是属于正常误差，还是由于肌肉疲劳或者肌肉发生了增长所产生的误差。并对误差结果进行矫正，并同时对矫正时的数据进行分析计算，确认病人是否需要继续进行刺激。此处避免了过量的刺激对病人造成的伤害，又能确保适量的刺激，加快病人的恢复进程。As the electrical stimulation proceeds, the muscles will gradually become fatigued, so it is necessary to analyze the muscle voltage error value to confirm whether the error is a normal error or an error caused by muscle fatigue or muscle growth. The error result is corrected, and at the same time, the data during the correction is analyzed and calculated to confirm whether the patient needs to continue stimulation. Here, the damage caused by excessive stimulation to the patient is avoided, and an appropriate amount of stimulation can be ensured to speed up the recovery process of the patient.

C1中下一个刺激节点的预选择方法是，由于病人的正常呼吸时肌肉电压上升时间T₁已知，且整个装置的延迟时间T₂已知，所以取上升时间T₁-T₂所对应的电压值V，作为电刺激节点。即当检测到肌肉电压处于上升状态，且当电压值上升到V时，中央处理器1控制放电装置4进行放电，使得腹部肌肉得以继续收缩，提高呼吸效率。刺激节点的选择可以使得放电装置4放电时，腹部肌肉处于自然收缩的最高点，在此时刺激肌肉，使得肌肉再次进行收缩，与病人的呼吸规律或者说呼吸时的肌肉收缩规律相配合，使得刺激效果最大化，同时也避免了呼吸冲突，可以提升病人每次呼吸时的呼吸量，有利于病人及早康复。The pre-selection method of the next stimulation node in C1 is, since the patient’s muscle voltage rise time T₁ is known during normal breathing, and the delay time T₂ of the whole device is known, so take the corresponding rise time T₁ -T₂ Voltage value V, as the electrical stimulation node. That is, when it is detected that the muscle voltage is rising, and when the voltage value rises to V, thecentral processing unit 1 controls thedischarge device 4 to discharge, so that the abdominal muscles can continue to contract and improve the breathing efficiency. The selection of stimulation nodes can make the abdominal muscles at the highest point of natural contraction when thedischarge device 4 discharges. At this time, the muscles are stimulated to make the muscles contract again, which matches with the patient's breathing law or the muscle contraction law during breathing, so that The stimulation effect is maximized, and breathing conflict is avoided at the same time, which can increase the breathing volume of the patient every time he breathes, and is conducive to the early recovery of the patient.

C7中的N₆的计算方式为(V_max0-V_max1)/V_max0。The calculation method of N₆ in C7 is (V_max0 −V_max1 )/V_max0 .

本申请中的方法的主要目的为，通过符合病人呼吸规律的电刺激，使得病人的吸氧量增大，并同时对病人的腹部肌肉进行锻炼，使得病人早日脱离呼吸机进行自主呼吸。The main purpose of the method in this application is to increase the patient's oxygen uptake through electrical stimulation that conforms to the patient's breathing pattern, and at the same time exercise the patient's abdominal muscles, so that the patient can get out of the ventilator for spontaneous breathing as soon as possible.
