[0015] In order to make the patent purposes, technical schemes and advantages of the utility model clearer and more apparent, the utility model is further described in detail below in combination with the drawings and examples.

[0016] In order to explain the technical scheme of the utility model, the following is described through specific examples.

[0017] In order to facilitate the description, only the parts related to the utility model examples are shown.

[0018] In combination Figures 1-3 As shown in the figure, the oxygen valve comprises a valve seat 1, an air inlet pipe 2 communicated with the upper end of the valve seat 1, an air outlet pipe 3 communicated with the lower end of the valve seat 1 in the shape of inverted Y, a valve cover 4 rotatably arranged in the valve seat 1, a cover plate 5 on the front surface of the valve cover 4, a plurality of shunt round holes 6 opened on one side of the inner wall of the valve cover 4, and an arc-shaped oxygen groove 7 opened on the other side of the inner wall of the valve cover 4, wherein the diameter of the shunt round holes 6 decreases from bottom to top, and the distance from the center of all shunt round holes 6 to the cover plate 5 is equal.

[0019] The medical oxygen shunt is one of the important equipment indispensable in the modern medical system. Its appearance not only solves the bottleneck problem in the traditional oxygen supply mode, but also improves the efficiency and quality of medical services, and provides strong support for the rehabilitation and treatment of patients. In the medical environment, especially in emergency treatment, intensive care and long-term care scenes, the oxygen valve can be used to simultaneously supply oxygen to two patients who need oxygen support.

[0020] The oxygen valve comprises a valve seat, an upper end of which is communicated with an air inlet pipe and a lower end of which is communicated with an air outlet pipe. In actual application, the air inlet pipe is connected with an oxygen outlet end of an oxygen supply source, which can be an oxygen cylinder or an oxygen generator. The air outlet pipe can be communicated with an oxygen inhalation mask or a nasal catheter of a patient.

[0021] As Figure 1 , a hook 8 is arranged on the back of the valve seat 1. When the oxygen valve is installed, the oxygen valve can be hung at the corresponding position by means of the hook.

[0022] In actual normal oxygen supply to a patient, the bottom opening of the air inlet pipe is located at the upper end of an oxygen slot, and the top opening of the air outlet pipe is located at the lower end of the oxygen slot. The size of the oxygen slot is matched with that of the bottom opening of the air inlet pipe and the top opening of the air outlet pipe. At this time, the oxygen supply amount is maximum.

[0023] In the process of oxygen supply to a patient by means of the oxygen valve, the oxygen supply amount can be adjusted according to actual conditions. As shown in FIG. 2-3, when the oxygen supply amount is to be adjusted, the valve cover can be rotated counterclockwise. The valve cover is rotated counterclockwise relative to the valve seat. In the process of rotation of the valve cover, the shunt circular hole moves towards the top opening of the air outlet pipe, and the oxygen slot moves towards the bottom opening of the air inlet pipe. Since the diameter of the shunt circular hole decreases from bottom to top, the oxygen supply amount decreases when the valve cover is rotated until the required oxygen supply amount is reached.

[0024] As a preferred structure, as Figure 1 , a set of tooth grooves 9 are formed on the edge of the cover plate 5. The cover plate 5 is marked with corresponding oxygen supply amount marks 10 corresponding to each shunt circular hole 6. The upper end of the air outlet pipe 3 is provided with an indicating arrow 11.

[0025] In the above structure, a set of tooth grooves are formed on the edge of the cover plate. When the valve cover is rotated, the medical staff holds the cover plate with the hand contacting the tooth grooves, so that the valve cover is more labor-saving when rotated. The cover plate is marked with corresponding oxygen supply amount marks corresponding to each shunt circular hole. In this embodiment, as Figure 1 , the oxygen supply amount marks are 100%, 90%, 80%, …, 10% from bottom to top. When the top opening of the air outlet pipe is located in the oxygen slot, the indicating arrow points to 100%, and the corresponding oxygen supply amount marks of the shunt circular holes decrease from bottom to top.

[0026] The oxygen supply amount marks are arranged on the cover plate, so that the oxygen supply amount can be more accurately adjusted. When the oxygen supply amount to a patient is adjusted, the valve cover is rotated, and the indicating arrow points to the corresponding oxygen supply amount mark, so that the whole adjustment process is relatively convenient.

[0027] Further, as a preferred structure, the air outlet pipe 3 has two air outlets, and the air outlet pipe is provided with an adjusting switch 12 at the intersection of the two air outlets.

[0028] When two patients are supplied with oxygen at the same time by using the oxygen valve, the opening and closing of the two air outlets can be controlled by rotating the adjusting switch. In actual conditions, when the knob of the adjusting switch is vertically arranged, the two air outlets are opened at the same time. If the right air outlet is to be closed, the adjusting switch is rotated reversely, the inner valve of the adjusting switch is rotated towards the right air outlet, until the adjusting switch is rotated by 90 degrees, at which time the inner valve completely covers the right air outlet.

[0029] In addition, the air inlet pipe 2 and the air outlet pipe 3 are both provided with a mark arrow 13. The mark arrow is used to distinguish the flow direction of oxygen when oxygen is supplied. In this way, the installation is more clear and error is avoided.

[0030] The above only describes the preferred embodiments of the present application, and is not used to limit the present application. Any modification, equivalent replacement and improvement within the spirit and principle of the present application shall be included in the protection scope of the present application.
