Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of medical devices, in particular to a light-proof bag. Background Art
[0002] In clinical nursing, many liquid infusions need to be protected from light, so containers with liquids (such as bottled liquids) need to be put into light-proof bags for use. However, in actual use, the liquid scale cannot be seen in the light-proof bag, so it is not easy to control the amount of liquid input. In this way, when part of the liquid in the container needs to be input, the light-proof bag can only be removed frequently to check the amount of liquid input, which is not conducive to protecting the liquid from light. Utility Model Content
[0003] The purpose of the utility model is to solve the shortcomings of the prior art and to propose a light-proof bag to solve the above-mentioned technical problems.
[0004] The technical solution of the utility model is as follows:
[0005] A light-proof bag comprises a light-proof bag body, the light-proof bag body is provided with an opening, a zipper for opening or closing the opening is installed at the opening, an interlayer is provided on one side of the light-proof bag body, a bottle cork puncture needle is provided at the bottom of the light-proof bag body, and the interior of the bottle cork puncture needle is connected with the interlayer; a boss is provided on the bottom surface of the light-proof bag body, the boss is provided corresponding to the bottle cork puncture needle, the boss is provided with a center hole connected with the interior of the bottle cork puncture needle, and the diameter of the center hole is smaller than the inner diameter of the bottle cork puncture needle.
[0006] Preferably, the other side and the top of the light-proof bag body are both provided with openings.
[0007] Preferably, the opening on the other side of the light-proof bag body and the opening on the top are integrally arranged.
[0008] Preferably, the bottom end of the opening on the other side of the light-proof bag body is arranged close to the bottom of the light-proof bag body.
[0009] Preferably, a surface of the interlayer close to the outer side of the light-shielding bag is evenly provided with a plurality of arc-shaped protrusions from top to bottom.
[0010] Preferably, the light-proof bag body is made of rubber or silicone.
[0011] Preferably, a through hole is provided on the top of the light-proof bag body.
[0012] When the light-proof bag of the utility model is in use, the zipper is opened to place the container with liquid (such as bottled liquid) into the light-proof bag body through the opening, and then the zipper is closed; when placing the bag, the sharp needle of the infusion set is inserted into the inside of the sharp needle of the bottle stopper along the center hole on the boss, and the sharp needle of the bottle stopper is inserted into the bottle stopper of the container with liquid, so that the liquid in the container with liquid will flow down through the sharp needle of the bottle stopper into the interlayer and the sharp needle of the infusion set. During the liquid infusion process, as the liquid in the container decreases, the liquid level in the container decreases. When the liquid level is lowered to the height position of the interlayer, the liquid level in the interlayer also decreases accordingly. In this way, after the liquid level in the interlayer is lowered, the liquid-free part has no hydraulic pressure and therefore becomes deflated. The user can understand the amount of liquid input by observing the deflated position, and there is no need to frequently remove the light-proof bag to check the amount of liquid input, which is conducive to light protection of the liquid.

[0017] In the figure: a light-proof bag body 1, a zipper 2, an interlayer 3, a bottle stopper puncture needle 4, a boss 5, a center hole 6, an arc-shaped protrusion 7, and a through hole 8. DETAILED DESCRIPTION
[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.
[0019] Example 1, reference Figure 1-Figure 3 The present embodiment is a light-proof bag, comprising a light-proof bag body 1, wherein the light-proof bag body can be made of rubber or silicone, an opening is provided on the light-proof bag body, a zipper 2 for opening or closing the opening is installed at the opening, an interlayer 3 is provided on one side of the light-proof bag body, a bottle cork puncture needle 4 is provided at the bottom of the light-proof bag body, and the interior of the bottle cork puncture needle is connected with the interlayer; a boss 5 is provided on the bottom surface of the light-proof bag body, the boss is provided corresponding to the bottle cork puncture needle, and a center hole 6 connected with the interior of the bottle cork puncture needle is provided on the boss, and the diameter of the center hole is much smaller than the inner diameter of the bottle cork puncture needle.
[0020] When the above-mentioned light-proof bag is used, the zipper is unzipped and the container with liquid (such as bottled liquid) is placed into the light-proof bag body through the opening, and then the zipper is closed; when placed, the spike needle of the infusion set is inserted into the inside of the spike needle of the bottle stopper along the central hole on the boss, and the spike needle of the bottle stopper is inserted into the bottle stopper of the container with liquid, so that the liquid in the container with liquid will flow down through the spike needle of the bottle stopper into the interlayer and the spike needle of the infusion set. During the liquid infusion process, as the liquid in the container decreases, the liquid level in the container decreases. When the liquid level is lowered to the height position of the interlayer, the liquid level in the interlayer also decreases accordingly. In this way, after the liquid level in the interlayer decreases, the liquid-free part has no hydraulic pressure and thus becomes deflated. The user can understand the amount of liquid input by observing the deflated position, and does not need to frequently remove the light-proof bag to check the amount of liquid input, which is conducive to light protection of the liquid. Of course, when the user observes that the deflated position of the interlayer reaches near the expected position, the zipper can also be unzipped to observe the liquid level and scale of the container with liquid to determine the amount of liquid input.
[0021] In one implementation, the other side and the top of the light-proof bag body are both provided with openings, and the opening on the other side of the light-proof bag body and the opening on the top are integrated so that the opening is larger, which is convenient for placing a container with liquid into the light-proof bag body and operating the stopper piercing needle to pierce the stopper of the container; the zipper on the other side of the light-proof bag body can be opened to observe the liquid level in the container and the scale position on the container.
[0022] Of course, in actual production, only an opening may be provided on the other side of the light-proof bag body. Preferably, the bottom end of the opening on the other side of the light-proof bag body is provided close to the bottom of the light-proof bag body. In this way, the zipper may be provided close to the bottom of the light-proof bag body, and the zipper buckle may be pulled upward to open it. In this way, when most of the liquid in the container needs to be input, only a small part of the zipper needs to be opened to observe the liquid level in the container and the scale position on the container.
[0023] In order to facilitate hanging of the light-proof bag, a through hole 8 is provided on the top of the light-proof bag body. The through hole is preferably arranged above the zipper, so that the light-proof bag can be hung for use by hooking the through hole.
[0024] Example 2, reference Figure 4 The structure of Example 2 is substantially the same as that of Example 1, except that: a plurality of arc-shaped protrusions 7 are evenly arranged from top to bottom on one side of the interlayer close to the outer side of the light-shielding bag. After the liquid enters the interlayer, the arc-shaped protrusions bulge outward under the action of the liquid pressure. When the liquid level in the interlayer drops, the arc-shaped protrusions become deflated, making them easier to be noticed by the user.
[0025] The above description is only a preferred specific implementation manner of the present utility model, but the protection scope of the present utility model is not limited thereto. Any technician familiar with the technical field within the technical scope disclosed by the present utility model can make equivalent substitutions or changes based on the technical scheme and utility model concept of the present utility model, which should be covered by the protection scope of the present utility model.
