The utility model relates to the technical field of infusion apparatuses, in particular to an anti-backflow adjusting piece for an infusion apparatus, which is convenient to operate and comprises an infusion bottle body and an anti-backflow adjusting component, a bottle stopper puncture device is mounted at the bottom of the infusion bottle body, and a vein infusion tube is connected to the bottom of the bottle stopper puncture device. An anti-backflow adjusting assembly is installed on the outer side of the vein infusion tube and comprises a pre-fixing sleeve, a connecting plate, an adjusting sleeve, anti-skid ring pieces and magnetic adsorption pieces, the pre-fixing sleeve is arranged on the outer wall of the upper end of the vein infusion tube in a sleeving mode, and the anti-skid ring pieces are installed on the inner wall of the pre-fixing sleeve in an arrayed mode; a connecting plate is arranged outside the pre-fixing sleeve, and an adjusting sleeve is mounted at the other end of the connecting plate; the anti-backflow structure solves the problems that in the prior art, an existing anti-backflow structure for an infusion apparatus is complex in structure, most of the anti-backflow structures are used for connection of the connector end of an infusion tube, the anti-backflow structure cannot adapt to common vein infusion apparatuses, and the application range is poor.

A bottle stopper puncture outfit is arranged at the upper end of an infusion tube, an injection needle is installed at the lower end of the infusion tube, a Murphy's dropper is arranged on the infusion tube close to an air filter, a medicine adding tube is arranged at the upper end of the Murphy's dropper, and a fluid director is arranged in the Murphy's dropper. The fluid director comprises a fluid director body and a membrane flap which are connected with each other, the periphery of the fluid director body is hermetically connected with the inner wall of the Murphy dropper, a fluid guide port is formed in the middle of the fluid director body, the membrane flap is provided with a narrowed channel below the fluid director body, and the channel is communicated with the fluid guide port to form a fluid guide channel; the diversion channel is opened when liquid flows into the upper part, and is sealed and closed when no liquid flows into the upper part; when the liquid level is lower than a preset value, the upper part and the lower part are isolated through the flap seal, blood return is avoided, and the buzzer sounds to remind medical staff; a filter membrane is arranged on the pipeline to purify the liquid medicine; the external infusion tube is arranged on the pipeline, so that quick medicine injection and color distinguishing are facilitated, quick medical care identification is facilitated, and the working efficiency is improved.

The utility model relates to hemodialysis technical field especially, it is a kind of pipeline connecting device of immediate wear type artificial blood vessel, including subcutaneous tissue layer, the skin layer of being in the upper layer of subcutaneous tissue layer, the venous blood vessel and arterial blood vessel being arranged between subcutaneous tissue layer and skin layer and the artificial blood vessel being established between venous blood vessel and arterial blood vessel. In the utility model, the original artificial blood vessel structure is improved scientifically and rationally, venous transfusion port, arterial transfusion port, oval puncture bevel and rubber septum are arranged on artificial blood vessel, artificial blood vessel can be embedded between subcutaneous tissue layer and skin layer, and skin puncture hill, which is convenient for puncture needle to puncture and position, can be formed on skin layer, effectively reduce the risk problems such as surgical trauma, puncture risk, catheter infection, central vein stenosis and even occlusion of hemodialysis process of hemodialysis patient, thereby improve the security and stability of actual hemodialysis use.
