Detailed ways

[0014] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of them. example. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0015] As shown in Figure 1-2, an automatic oxygen regulation device for nursing care of critically ill patients, including a sleeve 1, a piston 2, a manual adjustment mechanism 3, an oxygen adjustment mechanism 4, the piston 2 is slidingly connected to the inner wall of the sleeve 1; The oxygen regulating mechanism 4 is arranged under the piston 2 and includes a vertical rod 401, a straight rod 402, a connecting mechanism 403, a valve 404, and a bracket 405. The vertical rod 401 is connected to the center of the piston 2, and the straight rod 402 is connected to the vertical rod 401. The two can rotate around the center of the joint. The other end of the straight rod 402 is connected to the valve 404 by the connecting mechanism 403, and the valve 404 is attached to the inner wall of the sleeve 1. The straight rod 402 is provided with a bracket 405, a bracket 405 and The straight rod 402 is connected to form a lever structure. The base of the bracket 405 is welded to the sleeve base 10. When the air pressure in the air chamber 8 changes, the piston 2 drives the vertical rod 401 to move up or down, and the vertical rod 401 drives the straight rod 402. If the right end moves up or down, the left end of the straight rod 402 will drive the valve 404 to move down or up accordingly, so that the degree of opening of the valve 404 changes. The bracket 405 and the straight rod 402 are connected to the center of the valve 404 The distance is twice the distance from the axis of the sleeve 1. When the piston rises or falls a small distance, the left end of the straight rod 402 drives the valve 404 to fall or rise twice the distance correspondingly. The door 404 is more sensitive to the feedback of the air pressure change in the air chamber. The connecting mechanism 403 includes a sleeved sliding end 4031 and a connecting end 4032, the sliding end 4031 is connected to the valve 404, the connecting end 4032 is connected to the straight rod 402, and the bottom of the sliding end 4031 is connected to The bottom of the end 4032 is connected with a second spring 4033. When the straight rod 402 rotates, the distance between the center of the straight rod 402 and the bracket 405 and the inner wall of the sleeve 1 will change. The second spring 4033 in the connecting mechanism 3 presses the valve 404 and The inner wall of the sleeve 1 is in closer contact; the manual adjustment mechanism 3 includes a threaded barrel 302, a bolt 301, a first spring 303, a ball 304, a bottom plate 305, the threaded barrel 302 is welded to the upper cover 9 of the sleeve, and the bolt 301 is connected to the thread The inner wall of the cylinder 302 is engaged. The bottom of the bolt 301 and the bottom plate 305 are connected by a first spring 303. The contact part of the first spring 303 and the bottom plate 305 is provided with a ball 304. When the rotation of the bolt 301 drives the first spring 303 to rotate, the design of the ball 304 can be To prevent the rotation of the other end of the first spring 303 from causing damage to the bottom plate 305, the bottom plate 305 and the piston 2 are glued together, and the rotating bolt 301 moves up or down in the threaded cylinder 302, and the first spring 303 can be stretched or compressed. The bottom plate 305 exerts upward pulling force or downward pressure on the piston 2 to move the piston 2 upward or downward, so that The degree of opening of the valve 404 changes, the amount of oxygen intake can be manually controlled and the initial position of the valve 404 can be adjusted manually; the lower part of the valve 404 is provided with a baffle 7 connected to the sleeve 1, the baffle 7 and the sleeve base 10. The upper surface of the baffle is flush with the bottom of the oxygen inlet to limit the initial position of the valve 404. The side wall of the sleeve 1 is provided with a through circular oxygen inlet 5 corresponding to the position of the valve 404. The oxygen inlet 5 and the sleeve 1 Axial symmetrical position is also provided with an oxygen outlet 6 the same as the oxygen inlet 5.

[0016] An entity implementation of the present invention is:

[0017] When in use, the oxygen inlet 5 is connected to an oxygen tank, and the oxygen outlet 6 is connected to an oxygen mask. When the patient's oxygen demand increases, more oxygen will be inhaled from the oxygen outlet 6, resulting in a decrease in air pressure in the air chamber 8. Under the action of the difference between the air pressure in the air chamber 8 and the outside atmospheric pressure, the piston 2 moves downward, and the vertical rod 401 moves downward with the piston 2, and the right end of the straight rod 402 is lowered under the action of the bracket 405.

When the left end rises, the opening degree of valve 404 increases, and the oxygen supply increases; when the patient's oxygen demand decreases, the amount of oxygen inhaled from the oxygen outlet 6 decreases, and the air pressure in the air chamber 8 rises, and the air pressure in the air chamber 8 and the outside atmospheric pressure Under the action of the strength difference, the piston 2 moves upwards, and the vertical rod 401 moves upwards with the piston 2, under the action of the bracket 405, the right end of the straight rod 402 rises, and the left end decreases. The opening degree of the valve 404 is reduced, and the oxygen supply is reduced. . At the same time, we can rotate the bolt 301 of the manual adjustment mechanism 3 upward or downward to make the first spring 303 exert an upward pulling force or downward pressure on the piston 2 to manually change the opening degree of the valve 404 and change the amount of oxygen supplied.
