Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of polypropylene interfaces, in particular to a polypropylene combined interface. Background Art
[0002] Polypropylene is a commonly used plastic material, known for its lightweight, corrosion-resistant, and easy-to-process properties. Polypropylene connectors are a crucial component of infusion bags, connecting the bag to the IV tubing or other container to ensure smooth fluid flow. These connectors are widely used in hospital wards and outpatient clinics to connect infusion bags to patients' veins. Typically made of polypropylene, these connectors offer sealing and corrosion resistance, allowing them to withstand prolonged contact with medications or nutrients.
[0003] When using a polypropylene composite interface, if the interface is soft and has sealing problems, leakage may occur. This can interrupt the infusion process, affecting drug delivery and therapeutic efficacy. Liquid leakage may also cause discomfort to the patient. Therefore, we have proposed a polypropylene composite interface that ensures a tight seal during the infusion process to reduce the occurrence of such problems. Utility Model Content

[0006] Preferably, the sealing and fixing structure includes two semicircular blocks, and the number of the semicircular blocks is symmetrical. The side walls of the semicircular blocks fit with the side walls of the reinforcement blocks. One side of the side wall of the semicircular block is fixedly connected with a protrusion, and the other side of the side wall of the semicircular block is fixedly connected with a circular groove. The inner side walls of the two semicircular blocks are connected to each other, and the outer wall of the protrusion is interference-connected with the inside of the circular groove. The inner ring walls of the two semicircular blocks fit with the outer wall of the polypropylene tube.
[0007] Preferably, the inner ring wall of the semicircular block is fixedly connected with a semicircular ring, and the side wall of the semicircular ring is in contact with the outer wall of the polypropylene tube.
[0008] Compared with the prior art, the beneficial effects of the present invention are as follows: before using the polypropylene interface for infusion, the two ends of the polypropylene interface are connected to the infusion tube and the infusion bag respectively, a symmetrical reinforcement block is set at the polypropylene tube mouth, and a sealing and fastening structure is set between the symmetrical reinforcement blocks. The polypropylene tube wall is fastened and sealed by symmetrical buckling, and the polypropylene tube and the sleeved infusion tube are clamped and fastened. The connection is maintained by sealing and fixing, ensuring that it is fixed and stable, and that the medicine or nutrients can flow smoothly. It can ensure a stable connection between the interface and the infusion tube, avoiding leakage and poor connection problems. The method is simple to operate and easy to master. Nursing staff can quickly and accurately complete the installation and fixation of the interface, reducing operation time. By tightening the sealing structure, leakage of medicine or nutrients at the tube mouth can be effectively prevented, thereby improving the safety of patients and the quality of care.
