[0002] In hospital enemas and other fluid infusion settings, a liquid storage device is required to store the liquid;

[0003] According to Chinese Patent Publication No. CN216417948U, a disposable medical liquid storage device and a medical infusion device are disclosed. The device has an impeller assembly installed at the lower end of the liquid storage container. The impeller assembly can be connected to an external motor assembly, which facilitates the disassembly and assembly of the disposable medical liquid storage device. Furthermore, in the power device, only the impeller assembly is a disposable consumable, while the motor assembly is an externally connected reusable component, which greatly reduces the cost of use.

[0004] However, the opening at the top of the liquid storage container in this technical solution is always open and does not have a sealing structure. During the process of adding the liquid to the storage container, it will come into a lot of contact with the outside air, which may cause bacteria in the outside air to contaminate the liquid and thus affect the normal use of the liquid. Therefore, we propose a disposable medical liquid storage box. Utility Model Content

[0005] The purpose of this invention is to provide a disposable medical liquid storage box, which solves the problems in the background art.

[0024] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0025] In the description of this utility model, unless otherwise stated, "a plurality of" means two or more; the terms "upper," "lower," "left," "right," "inner," "outer," "front end," "rear end," "head," "tail," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. In addition, the terms "first," "second," "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0026] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0027] like Figure 1-6As shown, this utility model provides a technical solution: a disposable medical liquid storage box, including a liquid storage box 1 and a box cover 2, with an injection tube 3 connected to the top of the box cover 2, and a sealing mechanism 4 provided between the box cover 2 and the liquid storage box 1, with the box cover 2 sleeved on the top of the liquid storage box 1;

[0028] The sealing mechanism 4 includes a rotating ring 406 and a plug 411. A slider 402 is fixedly installed on the inner wall of the cover 2. A groove 401 is opened on the outer wall of the liquid storage box 1. The slider 402 is slidably connected to the groove 401. A spring 405 is fixedly connected between the top of the slider 402 and the top of the inner wall of the groove 401. The rotating ring 406 is slidably connected to the bottom of the cover 2. A limit block 410 is fixedly installed on the inner wall of the rotating ring 406. An L-shaped groove 409 is opened on the outer wall of the liquid storage box 1. The limit block 410 is slidably connected to the L-shaped groove 409. The plug 411 is located inside the liquid storage box 1 near the top. A support plate 412 is fixedly connected between the outer wall of the plug 411 and the inner wall of the liquid storage box 1. The plug 411 is inserted into the bottom of the injection tube 3. A sealing sleeve 413 is fixedly fitted on the outer wall of the plug 411. The sealing sleeve 413 is tightly fitted to the inner wall surface of the injection tube 3.

[0029] Specifically, in the above technical solution, when using the disposable medical liquid storage box 1, pulling the lid 2 upward causes the lid 2 to drive the slider 402 to compress the spring 405, causing the lid 2 to drive the limiting block 410 to slide upward in the vertical groove of the L-shaped groove 409. The lid 2 then moves the injection tube 3 upward, causing the injection tube 3 to disengage from the block 411, thus preventing the block 411 from blocking the injection tube 3. Then, rotating the rotating ring 406 causes the rotating plate to drive the limiting block 410 to slide into the horizontal groove of the L-shaped groove 409, allowing the limiting block 410 to limit the rotating ring 406 and thus fix the lid 2. At this time, personnel can add liquid to the liquid storage box 1 through the injection tube 3. After the injection is completed, the rotating ring 406 can be rotated in the opposite direction, causing the rotating ring 406 to drive the limiting block 410 to slide out of the horizontal groove of the L-shaped groove 409 and rotate to the junction with the vertical groove of the L-shaped groove 409. This causes the limiting block 410 to no longer limit the rotating ring 406. At this time, the rotating ring 406 is released, and the slider 402 will drive the cover 2 downward under the reset force of the spring 405. The cover 2 will drive the injection tube 3 downward, and finally the blocking block 411 will seal the bottom of the injection tube 3 again. With the above structure, it is convenient for personnel to seal the liquid storage box 1 in time after adding liquid, reduce the contact between the liquid and the outside air, greatly reduce the possibility of liquid contamination, and play a good protective role for the liquid. It solves the problem that the opening of the liquid storage container at the top is always open and does not have a sealing structure. During the process of adding liquid to the liquid storage container, a large amount of contact with the outside air will occur, which may cause bacteria in the outside air to contaminate the liquid and affect the normal use of the liquid.

[0030] Furthermore, a limiting rod 404 is fixedly installed on the inner wall of the slide 401, and a rod hole 403 is opened on the slider 402. The limiting rod 404 moves through the rod hole 403, and a spring 405 surrounds the outer wall of the limiting rod 404.

[0031] The limiting rod 404 can limit the spring 405 to ensure the stability of the spring 405 during compression.

[0032] Furthermore, a limiting ring plate 407 is fixedly installed at the top of the rotating ring 406, and a limiting ring groove 408 is opened at the bottom of the cover 2. The limiting ring plate 407 and the limiting ring groove 408 are slidably connected.

[0033] Among them, by setting the limiting ring plate 407, the rotating ring 406 can be limited, so that the rotating ring 406 can be fixedly rotated at the bottom of the box cover 2.

[0034] Furthermore, a sealing gasket 5 is fixedly installed on the top of the inner wall of the lid 2, and the sealing gasket 5 is tightly attached to the top surface of the liquid storage box 1.

[0035] By setting a sealing gasket 5, the sealing between the lid 2 and the liquid storage box 1 can be increased.

[0036] Furthermore, a cross baffle 8 is fixedly installed on the inner wall of the liquid storage box 1, and a protruding strip 6 is fixedly installed on the outer wall of the rotating ring 406;

[0037] By setting a cross baffle 8, the liquid in the liquid storage box 1 can be divided, thereby improving the stability of the liquid in the liquid storage box 1.

[0038] Furthermore, the outer wall of the liquid storage box 1 is provided with grooves 7, and the number of grooves 7 is several;

[0039] The groove 7 is provided to increase the roughness of the outer surface of the liquid storage box 1, which makes it easier for personnel to fix or support the liquid storage box 1.

[0040] The embodiments of this utility model are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the utility model to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described in order to better illustrate the principles and practical applications of this utility model, and to enable those skilled in the art to understand this utility model and design various embodiments with various modifications suitable for a particular purpose.
