[0007] The first state is that the end of the positioning pin is engaged in the positioning hole. At this time, when the valve plate is rotated by the rotating rod on the rotating knob of the oxygen flow meter, the positioning pin can be elastically deformed and disengaged from the positioning hole, but with resistance;

[0008] The second state is that the positioning pin is completely engaged in the positioning hole. At this time, the rotating rod is positioned and the rotating knob of the oxygen flow meter cannot rotate.

[0013] The utility model is a medical improved oxygen flow meter, which has the following beneficial effects:

[0014] The utility model discloses an improved medical oxygen flow meter. When the rotating knob of the oxygen flow meter is pressed, the positioning pin can be completely engaged in the positioning hole. At this time, the positioning pin is in the second state, which realizes the positioning of the rotating knob of the oxygen flow meter and avoids the problem of flow change caused by the patient's private adjustment and accidental contact with the knob.

When an element is considered to be "connected, connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. "Fixed connection" means a fixed connection. There are many ways of fixed connection, which are not within the scope of protection of this article. The terms "vertical", "horizontal", "left", "right" and similar expressions used in this article are for illustrative purposes only and do not represent the only implementation method.

[0027] Unless otherwise defined, all technical and scientific terms used herein have the same meanings as those commonly understood by those skilled in the art of the present invention. The terms used in the specification are only for the purpose of describing specific implementations and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0028] In Example 1, please refer to the attached Figures 1 to 6 The utility model provides a technical solution: a medical improved oxygen flow meter, including an oxygen cylinder 1, an oxygen cylinder pipe 2 is arranged on the oxygen cylinder 1, an oxygen flow meter rotating knob 3 is arranged on the oxygen cylinder pipe 2, and the oxygen flow meter rotating knob 3 is a conventional control valve for controlling the size of the internal channel of the oxygen cylinder pipe 2, which will not be described in detail here.

[0029] In order to solve the problem that the current oxygen flow meter knob rotation process has no damping, and the patient may adjust the knob privately or touch the knob by mistake, resulting in a change in flow rate, the utility model provides a rotating rod 4 fixedly arranged on the side of the oxygen flow meter rotating knob 3 close to the oxygen cylinder pipeline 2, and a valve plate 5 is movably arranged in the oxygen cylinder pipeline 2, and the valve plate 5 and the rotating rod 4 are connected by a cylindrical hardware connector 12, one end of the cylindrical hardware connector 12 is fixedly connected to the valve plate 5, and the other end of the cylindrical hardware connector 12 is fixedly provided with a sliding block 9, and an inner portion of the rotating rod 4 close to the valve plate 5 is provided A sliding groove 8 is provided, and a sliding block 9 is slidably arranged in the sliding groove 8. A locating pin 10 is fixedly arranged on one side of the rotating rod 4 close to the oxygen cylinder pipeline 2. A locating hole 11 is arranged on one side of the oxygen cylinder pipeline 2 close to the rotating rod 4. There are multiple locating holes 11, and the multiple locating holes 11 are distributed in a circular array along the axis of the rotating rod 4. The locating pin 10 is engaged in the corresponding locating hole 11. The locating pin 10 is an elastic column structure. The locating pin 10 has two states: the first state is that the end of the locating pin 10 is engaged in the locating hole 11. At this time, the oxygen flow meter is rotated When the rotating rod 4 on the knob 3 drives the valve plate 5 to rotate, the positioning pin 10 can be elastically deformed and disengaged from the positioning hole 11, but with resistance; the second state is that the positioning pin 10 is completely engaged in the positioning hole 11. At this time, the rotating rod 4 is positioned and the oxygen flow meter rotating knob 3 cannot rotate; when working, when the oxygen flow meter rotating knob 3 is pressed, the positioning pin 10 can be completely engaged in the positioning hole 11. At this time, the positioning pin 10 is in the second state, which realizes the positioning of the oxygen flow meter rotating knob 3 and avoids the problem of patients adjusting the oxygen flow meter privately and accidentally touching the knob to cause flow changes. When the oxygen flow meter rotating knob 3 is pulled out, the positioning pin 10 moves outward, and only a section of the end of the positioning pin 10 is located in the positioning hole 11. Since the positioning pin 10 is elastically deformable, when the oxygen flow meter rotating knob 3 is rotated, the positioning pin 10 can be elastically deformed and moved out of the positioning hole 11. At this time, the position of the valve plate 5 can be smoothly adjusted to achieve the adjustment of the channel size in the oxygen cylinder pipeline 2. There are multiple positioning holes 11, and the flow rate can be conveniently adjusted according to different gears. There is also a certain damping effect when adjusting the flow rate, and the hand feel is good and easy to control.

[0030] It should be noted that a rotational connection is required between the cylindrical hardware connector 12 and the oxygen cylinder pipe 2. A sealing ring is provided at one end of the cylindrical hardware connector 12 close to the valve plate 5 and fits against the inner wall of the oxygen cylinder pipe 2 to achieve a sealing effect; and a rubber pad is fixedly provided at the inner wall position of the sliding groove 8 that passes through the end of the rotating rod 4, so that when the rotating knob 3 of the oxygen flow meter is pulled, the rubber pad on the inner wall of the sliding groove 8 is in frictional contact with the outer surface of the cylindrical hardware connector 12, which has a certain damping to avoid accidental contact.

[0031] It should also be noted that the sliding groove 8 is a square groove structure, and the sliding block 9 is a square block structure, which limits the sliding block 9 to move only along the length direction of the sliding groove 8 and cannot rotate. Therefore, when the oxygen flow meter rotating knob 3 is turned, the valve plate 5 can rotate inside the oxygen cylinder pipe 2, thereby adjusting the flow rate.

[0032] In the utility model, a cylindrical hardware support 13 is fixedly connected to one end of the valve plate 5 away from the cylindrical hardware connection piece 12, and the cylindrical hardware support 13 is rotatably connected to the inner wall of the oxygen cylinder pipe 2; when the valve plate 5 rotates, the cylindrical hardware support 13 also rotates, and has a supporting effect on the other end of the valve plate 5, so that the valve plate 5 rotates stably and the accuracy of regulating the flow is guaranteed.

[0033] In Example 2, please refer to the attached Figure 2 , Figures 4 to 6 The utility model provides a technical solution: a first gas channel 14 is arranged in a cylindrical hardware support 13, one end of the first gas channel 14 is sealed and clamped with a plug 15, the other end of the first gas channel 14 is communicated with a second gas channel 16, the second gas channel 16 is arranged inside a valve plate 5, rubber air bags 6 are fixedly arranged on the upper and lower surfaces of the valve plate 5, and the end of the second gas channel 16 away from the first gas channel 14 is communicated with the corresponding rubber air bag 6; in the actual use process, there is a situation where the valve plate 5 is damaged, resulting in the outer ring of the valve plate 5 not being able to fit well with the inner wall of the oxygen cylinder pipe 2, which means that the oxygen The problem of leakage will cause oxygen waste if it cannot be repaired in time. Therefore, when the plug 15 is opened, an inflation mechanism 7 is connected to the end of the first gas channel 14, and the inflation mechanism 7 inflates the first gas channel 14. The gas can enter the rubber airbag 6 along the first gas channel 14 and the second gas channel 16 in sequence to expand the rubber airbag 6. When the rubber airbag 6 is expanded to a suitable degree, no matter what tilt state the valve plate 5 is in at this time, the rubber airbag 6 can cut off the channel inside the oxygen cylinder pipe 2, thereby achieving the purpose of temporary sealing and avoiding the waste caused by continuous leakage of oxygen.

[0034] It should be noted that the inflation mechanism 7 may be any inflation device such as an air pump, a handheld air pump, etc., and is not limited here.

[0035] It should also be noted that the oxygen flow meter is arranged on the surface of the oxygen flow meter rotating knob 3, which will not be described in detail here, but is shown in the figure.

[0036] It is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modification, equivalent substitution or improvement made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
