Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of medical supplies, in particular to a light-shielding infusion bag for chemotherapy. Background Art
[0002] During clinical infusion, some of the infusion drugs include drugs that are easily photolyzed or oxidized under light, such as nimustine hydrochloride, cyclophosphamide, methotrexate, and adriamycin. These drugs need to be infused in the dark during injection. Clinically, when using such drugs for infusion in patients, an infusion bottle is usually wrapped with a light-shielding bag made of light-shielding material.
[0003] Currently, most of the used light-shielding bags are bags with openings at both the upper and lower ends. After the infusion bottle is placed into the light-shielding bag through the opening at the upper end of the light-shielding bag, the bottle mouth of the infusion bottle will pass through the opening at the lower end of the light-shielding bag and then be connected to the infusion set. However, the existing light-shielding bags have some deficiencies: when it is necessary to remove the light-shielding bag, due to the lower part of the light-shielding bag being closed, the infusion bottle blocks the light-shielding bag from moving upward to be taken away, and since the infusion set is inserted and connected below the infusion bottle, it cannot be directly moved downward to be taken away either. It is necessary to first pull out the infusion set and then take the infusion bottle upward from the infusion bag. When pulling out the infusion set, the residual liquid medicine in the infusion bottle is likely to splash out, causing occupational exposure to medical staff. Content of the Utility Model
[0004] The technical problem to be solved by the utility model is to provide a light-shielding infusion bag for chemotherapy, which can not only take the infusion bottle out of the infusion bag body laterally after use, without having to pull out the infusion set and then take out the infusion bottle, avoiding the splashing of the residual liquid medicine in the infusion bottle, but also ensure the light-shielding effect of the infusion bag.
[0005] The technical solution adopted by the utility model to solve its technical problems is: a light-shielding infusion bag for chemotherapy, including an infusion bag body. The upper and lower ends of the infusion bag body are respectively provided with a first opening and a second opening. The infusion bag body includes a first bag body and a second bag body which are integrally arranged. The first bag body and the second bag body can be laid flat and unfolded. Both the first bag body and the second bag body are provided with connecting parts. The first bag body and the second bag body can surround the infusion bottle and be fixed to the infusion bottle through the connecting parts. A hanging part is arranged on the upper side of the first bag body, and a hanging hole is opened on the hanging part. An extraction cord for driving the first opening to close is arranged inside the upper end of the infusion bag body. One end of the extraction cord extends out from the upper end of the first bag body, and the lower side of the hanging part is connected to the end of the extraction cord extending out of the first bag body.
[0006] Compared with the prior art, the beneficial effects of this solution are as follows: After the first bag body and the second bag body are surrounded around the infusion bottle to form a cylindrical shape, the first bag body and the second bag body are fixed to the infusion bottle through the connecting part to shield the circumference of the infusion bottle. After the infusion bag body is fixed to the infusion bottle, the hanging part arranged on the upper side of the first bag body is hung on the infusion rack. When the hanging part is hung on the infusion rack, the drawstring is automatically tightened under the gravity of the infusion bottle and the infusion bag body, so that the first opening at the upper end of the infusion bag body is closed, and the bottom of the infusion bottle is located below the first opening, thereby shielding the bottom of the infusion bottle, ensuring the light-shielding effect on the infusion bottle, and thus avoiding the reduction of drug efficacy; when the infusion is completed and it is necessary to remove the infusion bottle and separate the infusion bottle from the infusion bag body, the connecting part is opened to separate the end where the first bag body and the second bag body are connected, and then the infusion bottle is taken away laterally from between the first bag body and the second bag body. Compared with taking away the infusion bottle from the infusion bag body by moving the infusion bottle along its axial direction, taking away the infusion bottle laterally does not require pulling out the infusion set first, which can effectively prevent the residual liquid medicine in the infusion bottle from dripping outwards, thereby avoiding the occupational exposure of medical staff.
[0007] As a preferred embodiment of the present utility model, the connecting part includes a connecting ring and a connecting buckle respectively arranged on the mutually remote sides of the first bag body and the second bag body when they are laid flat, and the first bag body and the second bag body surrounded into a cylindrical shape are connected by snapping the connecting buckle into the connecting ring.
[0008] The beneficial effects of this solution: When light-shielded infusion is required, first wrap the first bag body and the second bag body around the infusion bottle. Since the infusion bottle is filled with liquid medicine and has a certain weight, compared with bonding the first bag body and the second bag body with magic tape, snapping the connecting buckle into the connecting ring can ensure that the shape after the first bag body and the second bag body are surrounded is more stable and will not easily spread out from the infusion bottle, thereby ensuring the light-shielding effect.
[0009] As a preferred embodiment of the present utility model, a first connecting surface and a second connecting surface are respectively arranged on the inner sides of the first bag body and the second bag body, and adhesive surfaces for bonding the two to each other are respectively arranged on the first connecting surface and the second connecting surface. Along the length direction of the infusion bag body after it is unfolded, the first connecting surface and the second connecting surface respectively extend out of the first bag body and the second bag body.
[0010] Advantages of this solution: Since both the connecting ring and the connecting buckle have a certain volume and are respectively arranged on the sides of the first bag body and the second bag body that are far away from each other when they are laid flat, there is a gap between the cylinders formed by the enclosure of the first bag body and the second bag body after the connecting buckle is snapped onto the connecting ring. When the first bag body and the second bag body are wrapped around the infusion bottle, first, the first connecting surface and the second connecting surface arranged on the inner sides of the first bag body and the second bag body are bonded to preliminarily connect the first bag body and the second bag body, and then the connecting ring and the connecting buckle are connected. This can not only cover the gap through the first connecting surface and the second connecting surface to ensure the light-shielding effect during infusion, but also further strengthen the connection between the first bag body and the second bag body.
[0011] As a preferred embodiment of the present utility model, a hanging portion is also provided on the upper side of the second bag body, and the two hanging portions are symmetrically arranged on the first bag body and the second bag body respectively. The upper sides of the first bag body and the second bag body are respectively provided with an outlet for the two ends of the drawstring to extend out, and the two hanging portions are respectively connected to one end of the drawstring extending out of the first bag body and the second bag body along the outlet.
[0012] Advantages of this solution: After the infusion bag body is wrapped and fixed to the infusion bottle, the two hanging portions symmetrically arranged on the first bag body and the second bag body are simultaneously hung on the infusion rack, avoiding the situation that the infusion bottle tilts when only one hanging portion is used for hanging, thereby avoiding affecting the treatment effect.
[0013] As a preferred embodiment of the present utility model, a rigid reinforcing ring is provided on the inner ring of the hanging hole.
[0014] Advantages of this solution: The strength of the hanging hole is further strengthened by the reinforcing ring provided on the inner ring of the hanging hole, avoiding deformation or even cracking after multiple hangings.
[0015] As a preferred embodiment of the present utility model, an observation opening is opened at the lower end of the infusion bag body, and a light-shielding piece that can completely cover it is movably connected above the observation opening. Adhesive surfaces for bonding the two are respectively provided on the lower side of the light-shielding piece and below the observation opening.
[0016] Advantages of this solution: When it is necessary to observe the liquid level in the infusion bottle, lift the light-shielding piece for observation. When there is no need for observation, put down the light-shielding piece and fix the light-shielding piece to the infusion bag body through the adhesive surface to completely cover the observation opening, avoiding affecting the light-shielding effect.
