And in each pair of supporting rods, one ends of the two supporting rods are rotationally connected through an adjusting assembly. The protection mechanism is arranged on the periphery of the infusion bag, the infusion bag body can be adjusted and controlled to be unfolded in a similar filling shape before injection liquid is injected, and therefore the situation that the infusion bag body is punctured by an infusion tube due to the fact that the two surfaces of the infusion bag are tightly attached when the infusion tube is punctured is avoided.

Description

Technical Field

[0001] The utility model relates to the technical field of infusion bags, and more specifically, to a protection mechanism for an infusion bag. Background Art

[0002] Infusion refers to the way of injecting a large dose of injection solution into the body through intravenous drip, which is a common treatment method in clinical practice. The large dose of injection solution in the infusion is usually packaged in a sealed glass bottle or plastic bottle and is input into the human body through an infusion tube, an infusion bag, etc. Among them, in the preparation work of infusion, it is necessary to pierce the infusion tube into the infusion bag body so that the injection solution can flow through the infusion bag, the infusion tube, etc. in sequence and then be smoothly and stably input into the body. However, when the infusion tube is pierced into the infusion bag, since the bag body without the injection solution is in a compressed and adhered state during transportation and storage, the operation of piercing the infusion tube is extremely likely to stab or even puncture the infusion bag, resulting in its inability to be used continuously.

[0003] In this regard, some improved measures to prevent the infusion bag from being punctured have been proposed. For example, the patent with the publication number CN219461919U provides a new type of infusion bag, including a hollow combined cap and a pull-ring cap. The combined cap includes a base, a shell, and a rubber sealing head. The shell is connected to the base, and the rubber sealing head is arranged on the inner wall of the combined cap. A locking structure is also arranged on the shell. When in use, the infusion tube connector presses down on the rubber sealing head, forcing the liquid flow outlet that was originally in a closed state to be pressed open, so that the combined cap can be connected to the infusion tube.

[0004] However, although the above-mentioned infusion bag can avoid using a puncture device to pierce the infusion tube, when pressing the infusion tube connector against the rubber sealing head, sufficient external force needs to be applied, which is too strenuous for most female nurses and affects their normal work efficiency and progress.

[0027] Example 1

[0028] As Figures 1 to 5 shown, this embodiment provides a protection mechanism for an infusion bag, that is, a protection mechanism is arranged on the outer periphery of the infusion bag 1. The side of the infusion bag 1 is in a folded shape. The protection mechanism includes a support frame 2 configured on the folded flange of the infusion bag 1. The support frame 2 includes multiple pairs of support rods 21, and each pair of support rods 21 is respectively arranged on the folded flanges of two adjacent infusion bags 1. In each pair of support rods 21, one ends of the two support rods 21 are rotatably connected through an adjustment assembly.

[0029] In this embodiment, the adjustment assembly includes a rotating ring 41 configured at the end of the support rod 21. A shaft bolt 42 is inserted through the rotating ring 41. A connecting ring 43 is configured in the middle section of the shaft bolt 42. Two surfaces of the connecting ring 43 are respectively rotatably clamped with the rotating rings 41 of a pair of support rods 21. Specifically, a rack 44 is annularly arranged on the surface of the rotating ring 41, and an annular groove 45 is concavely arranged on the surface of the connecting ring 43 close to the rack 44. The rack 44 and the annular groove 45 can be meshed. Under the action of the rack 44 and the annular groove 45, when a pair of support rods 21 rotate to the required position, they can be kept clamped and fixed. During the operation process, after the side of the infusion bag 1 is unfolded, the infusion bag 1 can be kept stably unfolded under the action of the adjustment assembly, which is convenient for medical staff to operate and simplifies the operation work required during the process of piercing the infusion tube.

[0030] By arranging a protection mechanism on the outer periphery of the infusion bag 1, it is realized that before injecting the injection solution, the body of the infusion bag 1 can be regulated to unfold in a state similar to being full, so as to avoid that when piercing the infusion tube, the infusion tube stabs the body of the infusion bag 1 due to the two surfaces of the infusion bag 1 being tightly attached.

[0031] In this embodiment, diversion components are configured at both the top and the bottom of the infusion bag 1. The adjustment assembly is configured at one end of the support rod 21 close to the diversion component, so that when the support rod 21 rotates through the adjustment assembly, the side of the infusion bag 1 unfolds or compresses.

[0032] In this embodiment, one end of the support rod 21 far from the diversion component is in an arc shape, so that the end of the support rod 21 is smoothly connected to the side of the infusion bag 1.

[0033] In this embodiment, the diversion component includes an extended edge 31, and the extended edge 31 is integrally formed with the infusion bag 1. A diversion tube 32 is inserted through the middle of the extended edge 31. One end of the diversion tube 32 is communicated with the inner cavity of the infusion bag 1. Two hanging holes 33 are also inserted through the extended edge 31, and the two hanging holes 33 are respectively arranged on both sides of the diversion tube 32. The diversion tube 32 in this embodiment is a common puncture tube in the existing infusion bag 1, and no specific improvement is made to the pipeline structure, etc. Those skilled in the art can directly use the puncture tube at the end of the existing infusion bag 1 as the diversion tube 32.

[0034] In the present embodiment, a support bar 11 is arranged at a position of the infusion bag 1 near the end of the guide tube 32. The support bar 11 can be formed integrally with the infusion bag 1 by hot-melt gluing or cold welding using the same material as the infusion bag 1 or the like. A person skilled in the art can cold weld the hot-sealing strength of 5-10N / 15mm according to actual use requirements, and adjust the width of the support bar 11 within the range of 2-5mm to save materials and achieve a protective effect at the same time; in addition, the middle section of the support bar 11 near the guide tube 32 is raised in a direction away from the inner cavity of the infusion bag 1 to provide a local expansion space, which does not affect the compression and storage of the infusion bag 1, and can also protect the infusion bag 1 from damage to a certain extent near the insertion site of the infusion tube.

[0035] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may be subject to various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
