Description
Technical field
This utility model relates to medical instruments field, specifically refers to a kind of respirator flexible pipe.
Background technology
Respirator, is that a kind of normal physiological that can replace, control or change people is breathed, and increases pulmonary ventilation volume, improves respiratory function, alleviates work of breathing consumption, saves the device of heart reservation ability.In the time of infant Complicated with Acute Respiratory Failure, invalid through positive expectant treatment, hypopnea and abundant expectoration and thick, expectoration difficulties, obstructing airway or generation pulmonary atelectasis, should consider tracheal intubation and respirator.Respirator must possess four basic functions,, to lung inflation, air-breathing to the conversion of exhaling, discharges alveolar gas and exhales to air-breathing conversion, moves in circles successively.Therefore must have: (1) the power of carrying gas can be provided, replace the work of human body respiration flesh; (2) can produce certain respiratory rhythm, comprise respiratory frequency and inspiratory/expiratory, to replace the function of human body respiration nervus centralis domination respiratory rhythm; (3) can provide suitable tidal volume (VT) or minute ventilation (MV), to meet the needs of respiratory metabolism; (4) the gas of supplying with, preferably through adding gentle humidifying, replaces human body nasal cavity function, and can supply with higher than amount of oxygen contained in atmosphere, to improve oxygen intake concentration, improves oxygenate.The operation principle of respirator is: when expiratory positive airway pressure, aspiratory action produces intrathoracic negative pressure, and alveolar and air flue negative pressure appear in the passive expansion of lung, thereby has formed the pressure differential between gas port and alveolar and complete air-breathing; Air-breathing rear thorax and elastance of lung retraction, produce contrary pressure differential and complete expiration.Therefore, eupnea is to produce alveolar by respiratory movement and gas port " initiative negative pressure differential " completes air-breathing due to body, thorax after air-breathing and elastance of lung retraction produces alveolar and exhales with gas port passivity positive pressure difference, the needs of ventilating to meet physiology.And breathing machine ventilation is to make gas port and alveolar produce positive pressure difference by external Mechanical Driven, be removing the rear thorax of external Mechanical Driven pressure and elastance of lung retraction generation alveolar and gas port passivity positive pressure difference and exhaling and exhale, all there is " passivity positive pressure difference " and complete breathing in the breathing cycle.
Respirator accessory mainly comprises main frame, screen, air compressor machine, humidifier, nebulizer, patient respiration pipeline and nose cup etc., in the time that the air-flow generating enters nose cup by air inlet short tube, nose cup frame is isolated by extraneous air, avoids harmful gas or toxic gas enters into human respiratory; But in actual use, during as first aid or rescue way, user need to shift sick bed and can move the health of user, patient leans to one side or when rotation head, as child because active while being difficult to quiet down, the flexible pipe of respirator can constantly be moved, winding or distortion, not only can accelerate the wear and aging of respirator flexible pipe, also can make junction between flexible pipe and breathing mask occur lax and then cause ambient atmos to enter in human respiratory, particularly respiratory disease patient also can cause that sb.'s illness took a turn for the worse.
Utility model content
