Embodiment Construction
[0017] See attached figure 1 , 2 As shown in , 3, the present invention discloses a simple respirator that can determine and control the tidal volume, which is composed of four parts: a working cylinder assembly, a balloon, a pipeline assembly and a mask.
[0018] Wherein, the working cylinder assembly is composed of a matched piston cylinder 7 and a piston 8. The front end of the piston cylinder 7 is provided with a neck tube connection seat 6, and the tail end is provided with a balloon connection seat 14. The piston cylinder 7 is made of a transparent material. The outer wall is provided with a scale, and the rear side of the piston 8 is connected with a tension spring 15 that provides a reset tension to make it move backward; through the movement of the piston 8 in the piston cylinder 7, the suction and exhaust actions are realized.
[0019] The balloon 10 is made of elastic rubber material, and can be designed in an ellipse for easy handling and extrusion. It is fixed by...
