Abstract
The utility model discloses a volume-controllable respirator, which comprises a tracheal tube connector, a respirator valve and a respiration sac. The respiration sac is a cylindrical air sac and is placed in a cylindrical hard casing, the respiration valve is located at one end of the cylindrical casing, and a spring pressing mechanism and a respiratory volume control mechanism are further arranged in the casing. On the basis of retaining the respiration sac and the respiration valve of the original simple respirator, the volume-controllable respirator utilizes the laminated respiration sac with the hard transparent casing, by aid of a spiral boosting principle, a respiratory volume control rocker handle is rocked so as to lead a rack for adjusting volume scales to ascend and descend, and a spring extends and retracts by means of pressing a handle so that the foldable respiration sac is compressed and expanded, thereby leading air with certain volume to pass in and out from the respiratory tract of a patient and then achieving the purpose of controlling respiration manually. The volume-controllable respirator is particularly applicable to people group with severe requirements in terms of respiratory volume, such as infants, children and the like, and can also be used for artificial respiration for animals with light weight.
