Description

Technical Field

[0001] The utility model relates to the technical field of medical auxiliary devices, and particularly relates to a manual measuring device for the remaining liquid amount of a simple light-shielding infusion bag. Background Art

[0002] In medical care practice, light-shielding infusion bags are widely used to store light-sensitive drugs or liquids, aiming to maintain their chemical stability and therapeutic effectiveness. In response to this specific need, those skilled in the art have continuously explored innovative solutions to optimize the use experience of the light-shielding infusion system. For example, a light-shielding infusion device disclosed in Chinese Patent CN201798914U uses a light-shielding bag made of black dense cotton cloth, with hanging ears at its upper end for easy hanging, a zipper on the side for easy access, and a liquid outlet at the bottom. By opening this opening, the remaining liquid amount can be indirectly observed. This design effectively improves the light-shielding performance of the infusion bag and ensures the safe infusion of drugs that require light shielding.

[0003] However, although the above solution has achieved remarkable results in light-shielding protection, there are still deficiencies in measuring the remaining liquid amount in the light-shielding infusion bag. Specifically, the measurement process is not intuitive enough and the operation is cumbersome, bringing unnecessary troubles to the daily work of medical staff. Summary of the Utility Model

[0004] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a manual measuring device for the remaining liquid amount of a simple light-shielding infusion bag.

[0005] The technical solution adopted by the utility model is as follows:

[0006] A manual measuring device for the remaining liquid amount of a simple light-shielding infusion bag includes a light-shielding bag for holding an infusion bag made of plastic texture. The light-shielding bag is in the shape of a square bag, and its surface is coated with a light-shielding coating. A manual measuring device is integrated on the light-shielding bag, and the manual measuring device includes:

[0007] An opening on the side, provided on the side of the light-shielding bag, for taking and placing the infusion bag;

[0008] A hanging ring, provided at the top of the light-shielding bag, for cooperating with an infusion stand for hanging;

[0009] A squeezing sleeve ring, arranged in a ring shape, tightly sleeved on the light-shielding bag, and manually sliding the squeezing sleeve ring down to the top of the gradually deflated infusion bag;

[0010] Scales, vertically printed on the side of the light-shielding bag, for indirectly obtaining the remaining manual amount in cooperation with the squeezing sleeve ring that has moved down to the scale;

[0011] A bottom connection port, provided at the bottom of the light-shielding bag, for connecting the infusion bag to external instruments.

[0012] This technical solution realizes the manual measurement of the remaining liquid volume in the light-shielding infusion bag, while taking into account the requirements of light-shielding protection and the convenience of device use. Specifically, the surface of the light-shielding bag is coated with a light-shielding coating, which effectively blocks external light from entering the bag, protects light-sensitive drugs or liquids from being affected by light, and thus maintains their stability and effectiveness; as the liquid in the infusion bag gradually decreases, the volume of the infusion bag shrinks accordingly, manifested as the top gradually becoming shriveled. By manually sliding and squeezing the collar, it is made to move downward along the surface of the light-shielding bag until it closely adheres to the shriveled top of the infusion bag. During this process, the moving distance of the squeezing collar directly reflects the amount of liquid reduced in the infusion bag; the scale vertically printed on the side of the light-shielding bag provides an intuitive reference standard for the movement of the squeezing collar; when the squeezing collar moves down to a certain scale, the user indirectly obtains the remaining liquid volume in the infusion bag by observing the relative position of the scale and the squeezing collar. The method is simple and intuitive and easy to operate; the overall design of this device fully considers practicality and convenience. The side opening facilitates the taking and placing of the infusion bag, the hanging ring facilitates hanging the device on the infusion support, and the bottom connection port ensures the smooth connection of the infusion bag with external instruments (such as infusion tubes), jointly constituting a manually measuring device for the remaining liquid volume of the light-shielding infusion bag with perfect functions and simple operation.

[0013] In addition, the manually measuring device for the remaining liquid volume of the simple light-shielding infusion bag proposed above according to the present utility model further has the following additional technical features:

[0014] According to an embodiment of the present utility model, the height of the side opening meets the requirements of the infusion bag size.

[0015] This technical solution ensures that the height of the side opening meets the requirements of the infusion bag size to achieve the smooth taking and placing of the infusion bag, while ensuring the sealing performance and light-shielding effect of the light-shielding bag.

[0016] According to an embodiment of the present utility model, the top of the light-shielding bag is provided with a through hole that matches the hanging ring.

[0017] This technical solution enables the hanging ring to be stably installed on the light-shielding bag by providing a through hole that matches the hanging ring at the top of the light-shielding bag, facilitating the hanging and use of the entire device on the infusion support.

[0018] According to an embodiment of the present utility model, several protrusions are provided on the inner wall of the squeezing collar, and the protrusions are used to more closely contact the light-shielding bag inward.

[0019] This technical solution enables the squeezing collar to more closely contact the light-shielding bag during the sliding process by providing several protrusions on the inner wall of the squeezing collar, improving the accuracy and stability of the measurement and reducing the error caused by sliding.

[0020] According to an embodiment of the present utility model, when the extrusion collar moves downward, the deflated infusion bag is extruded more thoroughly until the extrusion collar moves downward to the top of the infusion bag and cannot move any further.

[0021] This technical solution is designed such that during the downward movement of the extrusion collar, the deflated infusion bag can be extruded more thoroughly until it can no longer move downward, thereby ensuring that the position of the extrusion collar can accurately reflect the remaining amount of liquid in the infusion bag.

[0022] According to an embodiment of the present utility model, the values indicated by the scale increase gradually from bottom to top, and the higher the value, the higher the remaining amount of liquid.

[0023] This technical solution enables the values indicated by the scale to increase gradually from bottom to top, intuitively showing the user the remaining situation of the liquid in the infusion bag. The higher the value, the more liquid remains, which is convenient for the user to quickly read and judge.

[0024] Compared with the prior art, the present utility model has the following beneficial effects:

[0025] (1) By manually sliding the extrusion collar to move it downward along the surface of the light-shielding bag until it closely adheres to the top of the deflated infusion bag, the moving distance of the extrusion collar directly reflects the amount of liquid reduced in the infusion bag during this process;

[0026] (2) The scale vertically printed on the side of the light-shielding bag provides an intuitive reference standard for the movement of the extrusion collar; by observing the relative position of the scale and the extrusion collar, the remaining amount of liquid in the infusion bag can be indirectly obtained;

[0027] (3) The side opening facilitates the taking and placing of the infusion bag, the hanging ring facilitates hanging the device on the infusion support, and the bottom connection port ensures the smooth connection between the infusion bag and external instruments, with complete functions and simple operation.
