[0023] The following will be combined with the embodiments to clearly and completely describe the technical solution of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0024] See also Figure 1-Figure 2 , the utility model provides a technical solution:

[0025] Example:

[0026] like Figure 1 and Figure 2 As shown, a quantitative simple artificial respirator includes a mask 1 and a balloon 2 connected to the mask 1. A quantitative extrusion component 3 is provided outside the balloon 2. The quantitative extrusion component 3 is used for quantitatively extruding the balloon 2, and the extrusion amount of the balloon 2 is adjustable.

[0027] like Figure 2 As shown, the quantitative extrusion assembly includes a bracket 4, a driving frame 5, a driving rod 6 and a mounting cylinder 7, the first end of the bracket 4 is rotatably connected to the first end of the driving frame 5 through a rotating shaft 8, (the second end of the driving frame 5 is freely arranged,) the driving rod 6 is telescopically arranged in the mounting cylinder 7, the end of the driving rod 6 away from the mounting cylinder 7 is hinged to the middle part of the driving frame 5, and the end of the mounting cylinder 7 away from the driving rod 6 is hinged to the bracket 4;

[0028] The balloon 2 is disposed in the mounting tube 7, and one end of the driving rod 6 located in the mounting tube 7 contacts the balloon 2;

[0029] The mounting tube 7 is provided with an adjusting member for controlling the extension and retraction amount of the driving rod 6 .

[0030] The wall of the mounting tube 7 is provided with a strip-shaped hole 9 along the axial direction, and the adjusting member includes a first retaining ring 10 and a second retaining ring 11, wherein the first retaining ring 10 is coaxially fixedly arranged outside the driving rod 6, and the second retaining ring 11 is coaxially slidably arranged on the inner wall of the mounting tube 7, and the second retaining ring 11 is located between the first retaining ring 10 and the balloon 2;

[0031] A fixing piece for fixing the second retaining ring 11 and the mounting tube 7 in cooperation with the strip-shaped hole 9 is disposed on the outer wall of the second retaining ring 11 .

[0032] The fixing member includes a bolt 12 and a nut 13 . The head of the bolt 12 is fixed to the outer wall of the second retaining ring 11 , and the tail of the bolt 12 extends out of the strip hole 9 and is connected to the nut 13 .

[0033] The diameter of the nut 13 is greater than the width of the strip-shaped hole 9 .

[0034] An annular friction plate (not shown in the figure) is arranged between the nut 13 and the outer wall of the mounting tube 7, and the friction plate is coaxially arranged on the bolt 12; the friction plate is made of rubber. Such an arrangement can increase the friction between the nut 13 and the outer wall of the mounting tube 7, thereby ensuring that the second retaining ring 11 does not move when the nut 13 is tightened.

[0035] The rotating shaft 8 is provided with a torsion spring 14 on the outside. The specific arrangement of the torsion spring 14 is as follows: Figure 2The torsion spring 14 is used to press the drive frame 5 and after releasing, the drive frame 5 is automatically reset under the action of the torsion spring 14 .

[0036] The balloon 2 is connected to the mask 1 via a bellows. In this way, when the balloon 2 is squeezed, a certain amount of deformation can be provided, thereby preventing the trachea between the balloon 2 and the mask 1 from being torn off. Of course, this problem can also be solved by increasing the margin of the trachea.

[0037] Working principle: (1) When in use, apply pressure to press the second end of the driving frame 5, so that the second end of the driving frame 5 moves toward the second end of the bracket 4; in this process, the driving frame 5 drives the driving rod 6 to move along the inner wall of the mounting tube 7 toward the bottom of the mounting tube 7, and when the driving rod 6 moves, it squeezes (compresses) the balloon 2, so that the balloon 2 releases gas into the mask 1.

[0038] When the driving frame 5 moves to the limit position, the balloon 2 completes a gas release action. Each time the balloon 2 and the mask 1 are used, the driving frame 5 is pressed to the limit position to achieve quantitative input of tidal volume. When the driving frame 5 is released, the driving frame 5 automatically resets under the action of the torsion spring 14.

[0039] (2) Adjustment of the tidal volume: When used for different patients, here we take the adjustment of the volume from small to large as an example: loosen the nut 13 so that the second retaining ring 11 can slide freely along the axial direction of the mounting tube 7; at this time, by moving the bolt 12, the bolt 12 moves along the strip hole 9 toward the bottom of the mounting tube 7, and the bolt 12 moves to drive the second retaining ring 11 to move synchronously. After the second retaining ring 11 moves, the stroke of the first retaining ring 10 is "released" and becomes larger. At this time, the stroke of the driving rod 6 increases synchronously, that is, the limit position of the driving frame 5 becomes larger (the minimum angle between the driving frame 5 and the bracket 4 becomes smaller). In this way, when the driving frame 5 moves to the limit position, the driving rod 6 squeezes the balloon 2 more, and then the compression of the balloon 2 becomes larger, so that the increase in the volume of the injection is achieved. When the injection volume needs to be reduced, the above operation can be performed in reverse.

[0040] The utility model can not only realize the quantitative feeding of tidal volume and accurately grasp the feeding amount of tidal volume by arranging the quantitative extrusion component, but also can adjust the feeding amount, which is convenient and quick to use.

It should be understood that the utility model is not limited to the form disclosed herein, and should not be regarded as excluding other embodiments, but can be used in various other combinations, modifications and environments, and can be modified within the scope of the concept described herein through the above teachings or the technology or knowledge of the relevant field.
