Description

Technical Field

[0001] The utility model relates to the technical field of three-way infusion, in particular to a three-way infusion nursing sleeve. Background Art

[0002] At present, an infusion three-way care set is a kind of care and protection equipment specially used in the medical field. This care set is usually designed to fix and protect the infusion line, especially those with three-way. The three-way infusion line is used to achieve liquid diversion and connection in the medical process, and the main function of the care set is to provide additional protection to prevent the line from being contaminated or damaged, thereby reducing the risk of infection.

[0003] The prior art has an authorization announcement number of CN217286701U, which is a kind of infusion three-way pipe orifice protection cover and infusion three-way pipe. The patent provides an infusion three-way pipe orifice protection cover, the main purpose of which is to effectively protect the pipe orifice of the infusion three-way pipe. The design features of the protection cover are mainly reflected in the following two aspects: first, it includes a protection cover body, which can be detachably installed on the pipe orifice of the infusion three-way pipe. This design enables the protection cover to fit the pipe orifice tightly during use, play a good protective role, and can be easily installed and disassembled, which is convenient for medical staff to operate. Secondly, the protection cover is also provided with a support part, which includes at least two support protrusions. These support protrusions are arranged along the height direction of the protection cover body to form a three-dimensional support structure. In particular, the thickness of the support protrusion is larger at the cover part away from the protection cover body, and gradually decreases at the cover part close to the cover. This design enables the support protrusion to provide stronger support force when subjected to external force, effectively preventing the pipe orifice from being compressed or deformed, and further enhancing the protection effect.

[0004] However, when the patent is in use, a circular protective cover is used to protect the tube mouth of the three-way pipe, which can ensure the connection between the three-way pipe and the infusion tube. However, when either the three-way pipe or the infusion tube is pulled, the protective cover cannot protect the connection, and its protection effect is poor. When the three-way pipe is in use, multiple three-way pipes are often required to be connected. When multiple three-way pipes are connected, deflection will occur, resulting in poor practicality.

[0005] The prior art has an authorization announcement number of CN203139222U for a medical infusion three-way tube protection device. The patent consists of two parts: a box body and a box cover. The box body and the box cover are movably connected. A plurality of semicircular openings are designed on the front of the box body. These openings coincide with the corresponding semicircular openings on the front of the box cover to form a plurality of complete circular holes. The main function of these circular holes is to serve as a fixed passage for the side passage of the medical infusion three-way tube to ensure the stable position of the three-way tube in the device. At the same time, a semicircular opening is also opened on the left and right sides of the box body, which coincide with the corresponding semicircular openings on the left and right sides of the box cover to form two circular holes respectively. These two circular holes are used to fix the main passage of the medical infusion three-way tube to ensure that the main passage is in the device. Stability and safety in the medical environment. This protective device can protect one or more medical infusion three-way tubes. By relatively fixing the main passage and the side passage of the three-way tube, the sterile management of the use area of ​​the medical infusion three-way tube is effectively achieved. This not only helps to reduce the incidence of nosocomial infection, but also can protect patients, standardize nursing operations, and improve the quality of medical care. In addition, the patent adopts PVC transparent material as a whole. This material not only has excellent durability and chemical stability, but also has high transparency, so that nursing staff can clearly observe the use of the medical infusion three-way tube used, which provides convenience for timely detection of problems and adjustment of nursing plans. This visual design greatly improves the efficiency and accuracy of nursing work.

[0006] However, when in use, the patent adopts a square box body for protection, and there is also a problem that when it is pulled, the protective cover cannot connect and protect it. When in use, the patent cannot connect multiple three-way pipes, and its practicality is poor. Utility Model Content
