[0027] The following will be combined with the drawings in the utility model embodiments to clearly and completely describe the technical solutions in the utility model embodiments. Obviously, the described embodiments are only part of the utility model embodiments, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] See also Figure 1-Figure 5 , the utility model provides the following technical solutions:

[0029] Embodiment 1

[0030] In order to solve the problem that the existing infusion bag net sleeve in the prior art is easy to rotate and move when being taken after being tightened, the following solution is disclosed, specifically as follows: Figure 1 , Figure 2 and Figure 3 As shown, it includes a left net cover body 1 and a right net cover body 2. The left net cover body 1 and the right net cover body 2 have the same structure and are symmetrical. The left net cover body 1 and the right net cover body 2 are both mesh structures, and the left net cover body 1, the tightening rope 6 and the right net cover body 2 are all made of nylon. Both sides of the left net cover body 1 and the right net cover body 2 are connected with a pull rope 3, the pull rope 3 is an aramid braided rope, and the diameter of the pull rope 3 is larger than the diameter of the left net cover body 1. At the same time, the pull rope 3 is connected to the left net cover body 1 and the right net cover body 2 through a dead knot. Both sides of the bottom of the left net cover body 1 and the right net cover body 2 are connected with a limit rod 7, the limit rod 7 is symmetrical about the central axis of the left net cover body 1, and the position of the limit rod 7 is lower than the position of the bottom end of the tightening rope 6. The first guide ring 4 is installed at both ends of the side away from the left net cover body 1, and the second guide ring 5 is installed at the bottom end of the right net cover body 2 below the first guide ring 4. A tightening rope 6 is penetrated inside the first guide ring 4. Two tightening ropes 6 are provided, and the tightening ropes 6 are symmetrical about the central axis of the left net cover body 1. The tightening rope 6 is fixedly connected to the left net cover body 1, and the tightening rope 6 is movably connected to the right net cover body 2 through the first guide ring 4 and the second guide ring 5. One end of the tightening rope 6 extends to the outside of the left net cover body 1 and is connected to the left net cover body 1, and the other end of the tightening rope 6 penetrates the inside of the second guide ring 5. At the same time, the other end of the tightening rope 6 passes through the bottom end of the right net cover body 2 and is connected to the bottom end of the left net cover body 1.

[0031] In this embodiment, when in use, the two first guide rings 4 are pulled apart to both sides, and then the infusion bag is placed between the left mesh main body 1 and the right mesh main body 2, and then the drawstring 3 is lifted upwards, so that the bottom end of the infusion bag is placed on the bottom end of the tightening rope 6 and the limit rod 7, so that the pipeline plug at the bottom end of the infusion bag passes through both sides of the limit rod 7, and due to the gravity of the infusion bag, the infusion bag first contacts the bottom end of the tightening rope 6, and then drives the tightening rope 6 to move downward along the second guide ring 5, and then the top end of the tightening rope 6 is contracted downward, so that the tightening rope 6 is pressed against the mesh. The upper opening is tightened to restrict the infusion bag to the inside of the mesh sleeve, and the tightening method will not affect the position of the drawstring 3. Since the two ends of the drawstring 3 are placed on both sides of the mesh sleeve, the infusion bag can be subjected to tension on both sides when it is hung, so as to reduce the rotation of the infusion bag during the taking process, so as to ensure the stability of the infusion bag. The drawstring 3 and the limiting rod 7 are cooperated to form a rectangular mesh bag structure for the infusion bag, so that the mesh sleeve can adapt to the shape characteristics of the infusion bag and make the limiting of the infusion bag more stable.

[0032] Embodiment 2

[0033] This embodiment is different from the first embodiment in that the protective cover is used to improve the comfort of taking the infusion bag, and the hanging rope is used to improve the adaptability of hanging the infusion bag. Figure 1 , Figure 4 , Figure 5 As shown, the outside of the pull rope 3 is provided with a protective sleeve 8, and the outside of the pull rope 3 on both sides of the protective sleeve 8 is provided with a locking ring 9, and anti-slip strips 10 are installed at both ends of the protective sleeve 8. The cross-section of the protective sleeve 8 is rectangular, and the protective sleeve 8 is located on the central axis of the pull rope 3. The anti-slip strips 10 are distributed at equal intervals on the protective sleeve 8. A groove 11 is opened on one side of the protective sleeve 8, and a slider 12 is installed inside the groove 11. The slider 12 forms a front-and-rear sliding structure with the groove 11 through a guide groove, and a hanging rope 13 is installed on one side of the slider 12.

[0034] In this embodiment, when in use, a locking ring 9 is used to prevent the protective sleeve 8 from sliding left and right along the drawstring 3, and an anti-slip strip 10 is used to increase the contact friction between the hand and the protective sleeve 8, which is beneficial to prevent the infusion bag from falling off when being taken, and at the same time prevents the single drawstring 3 from causing marks on the hand, and by tilting the protective sleeve 8 to one side, the slider 12 slides outward a certain distance inside the groove 11, and then the hanging rope 13 is moved out, and the infusion bag is hung by a thin hanging rope 13, and the different thicknesses of the protective sleeve 8 and the hanging rope 13 are utilized to make the suspension of the net sleeve adapt to different suspension conditions.

[0035] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
