In addition, the terms "first", "second", etc. are only used for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, the features defined as "first", "second", etc. may explicitly or implicitly include one or more of the features. In the description of the utility model, unless otherwise specified, the meaning of "multiple" is two or more.

[0015] Example 1

[0016] like Figure 1 , Figure 4The embodiment is composed of a filling container 1, a liquid inlet valve 2 and a boost nozzle 4 which are connected in sequence, wherein the liquid inlet valve 2 includes a plurality of liquid inlets 21 and a liquid outlet 22, and a needle valve 3 is provided between the liquid inlet valve 2 and the boost nozzle 4, and the liquid inlet valve 2 and the boost nozzle 4 are internally connected. The one-piece filling container 1 is in the shape of a cube, with an open top, and the interior is provided with four independent filling chambers 11 to 14 by diagonally fixed partitions, each of which has an opening at the bottom, and each opening at the bottom of the filling chamber is respectively connected to a liquid inlet of the liquid inlet valve. In some preferred embodiments, the filling container 1, the liquid inlet valve 2 and the needle valve 3 are connected by a medical infusion hose 5 ( Figure 1 ).

[0017] The booster nozzle 4 includes a liquid storage bag 41, and a protruding nozzle 42 ( Figure 4 On this basis, preferably, the liquid storage capsule is made of elastic material.

[0018] Each of the multiple medicine bottles is filled with only one prepared liquid medicine, for example, hydrogen peroxide, iodine tincture, or normal saline solution for flushing burn wounds.

[0019] Example 2

[0020] Based on Example 1, the needle valves of some embodiments have the following features: Figure 2 The structure of Figure 2 The cross section of the structure is shown, which is a state under normal pressure). The needle valve 3 includes a tube body 31 and a valve needle 32 inside the tube body. One end of the valve needle 32 is a flexible diaphragm 33, and the other end is a conical member 321. The flexible diaphragm 33 is fixed to the inner wall of the tube body 31 and is provided with through holes 331 around it. A retaining ring 34 is also provided on the inner wall of the tube body. The deformation of the flexible diaphragm 33 can drive the conical member 322 to penetrate into the hole of the retaining ring 34 and make the through hole on the flexible diaphragm 33 sealed by the retaining ring 34.

[0021] The needle valve 3 structure needs to be used in conjunction with the booster nozzle. When the pressure in the booster nozzle increases, the flexible diaphragm 33 bulges toward the retention ring 34, and the conical member 321 is inserted into the hole of the retention ring 34 to seal the gap. At this time, the needle valve is closed to prevent the liquid from flowing through the retention ring.

[0022] The liquid inlet valve, the needle valve and the boost nozzle are connected by an infusion hose. One end of the flexible diaphragm 33 of the needle valve 3 is connected to the liquid inlet end of the boost nozzle 4, and one end of the needle valve 3 close to the cone 321 is connected to the infusion hose 5. Figure 2 It is shown that when the pressure inside the booster nozzle is at normal pressure, the needle valve is opened, so that the liquid transported through the medical infusion hose 5 can flow into the inside of the booster nozzle 4 through the through hole on the flexible diaphragm 33 .

[0023] Example 3

[0024] Based on the above embodiments, the liquid inlet valve 2 of some embodiments is as follows Figure 3 In the structure shown, the sealed annular cavity 20 is composed of an upper cover 2A and a lower cover 2B that are movably connected. A partition 23 is provided on the inner wall of the annular cavity. The liquid outlet 22 is opened on the lower cover 2B of the liquid inlet valve. The partition has an opening. The multiple liquid inlets 21 are opened on the upper cover 2A of the annular cavity, and a sealing ring 210 is provided at a corresponding position on the inner wall of the upper cover of the annular cavity. The partition is fixed to the lower inner wall and rotates with the rotation of the lower cover. When its opening corresponds to the position of the liquid inlet 21, the liquid inlet valve 2 is in an open state. When the opening of the partition is staggered from the liquid inlet 21, the liquid valve 2 is in a closed state.

[0025] Although the utility model has been described in detail above by general description and specific implementation methods, it is obvious to those skilled in the art that some modifications or improvements can be made to the above embodiments. Therefore, these modifications or improvements made without departing from the spirit thereof all fall within the scope of the protection claimed.
