specific Embodiment approach 1

[0015] Specific implementation mode one: combine Figure 1 to Figure 3 Describe this embodiment, this embodiment includes driving system B, multiple transmission systems, mask B-7, tension rope G and housing C, described driving system B and described multiple transmission systems are installed in described housing In C, the tensioning rope G is buckled on the mask B-7 and extends into the housing C, passes through the multiple transmission systems, and finally the head and the end are all accommodated in the drive system B, The driving system B drives the head and the end of the tensioning rope G to move so that the length of the tensioning rope G outside the driving system B changes, and then converts the tensioning rope G to fasten the mask B The magnitude of the force of -7 varies; when tightened, the tensile force that the tension rope G experiences on the parts other than the drive system B is the same. Because the suffered pulling force is all the same everywhere on th...

specific Embodiment approach 2

[0016] Specific implementation mode two: combination figure 1 To describe this embodiment, the multiple transmission systems of this embodiment are installed in the housing C in a rectangular array, and the mask B-7 is located above the middle of the rectangular array. Such setting further makes the tensioning rope G symmetrically arranged with respect to each pulling force on the mask B-7, ensuring the mask pressing effect. Other components and connections are the same as those in the first embodiment.

specific Embodiment approach 3

[0017] Specific implementation mode three: combination image 3 To illustrate this embodiment, the drive system B of this embodiment includes a fastening motor B-1, a fastening motor seat B-2 and a double slot guide wheel B-3, and the fastening motor B-1 is installed on the On the fastening motor seat B-2, the double wire groove guide wheel B-3 is fixedly connected to the output shaft of the fastening motor B-1; the double wire groove guide wheel B-3 can accommodate the tension rope at the same time The head end of G, when the fastening motor B-1 is working, drives the double wire slot guide wheel B-3 to rotate, thereby tightening or loosening the head end of the tension rope G at the same time, so as to realize the length change of the wire rope G. This structure saves the internal space, and ensures the same stress on the head and end of the tension rope G, which is beneficial to improve the service life of the steel wire rope G.

Abstract

The invention discloses a mask fastening system and an anesthesia airway auxiliary management instrument, and relates to a fastening system and an airway auxiliary management instrument. The invention aims to solve the problems that an existing mask pressing mode can not adjust the pressing degree of a mask at any time, so that the mask can not be suitable for different types of patients and leaks. The driving system and a plurality of transmission systems of the mask fastening system are installed in a shell; a tensioning rope is buckled on the mask and stretches into the shell; through the plurality of transmission systems, the head end and the tail end of the tensioning rope are finally contained in the driving system; the driving system drives the head end and the tail end of the tensioning rope to move, the length of the part, which is out of the driving system, of the tensioning rope is changed so as to be converted into the change of force of the tensioning rope fo tightening the mask; and during tensioning, the tension applied to all parts, except the driving system, of the tensioning rope is the same. Two flexible arms are installed on the left side and the right side of the mask fastening system to form the anesthesia airway auxiliary management instrument. The anesthesia airway auxiliary management instrument is used for anesthesia airway auxiliary management.

Description

technical field [0001] The invention relates to a mask fastening system, in particular to a double-rope mask fastening system used for anesthesia airway auxiliary management equipment, and belongs to the field of anesthesia medicine. Background technique [0002] Mask ventilation belongs to non-invasive positive pressure ventilation (NPPV). The advantages of mask NPPV include: the airway management method is less irritating to the patient and more comfortable for the patient; it can avoid the destruction of the normal barrier function of the upper airway caused by the establishment of an artificial airway, Injury, respiratory infection and other complications. Studies have shown that face mask NPPV can be used for acute and chronic respiratory failure caused by various reasons, effectively relieve dyspnea, enhance gas exchange and improve oxygenation function, reduce the proportion of endotracheal intubation, shorten ICU and total hospitalization time, reduce mortality and ...
