AI Technical Summary

Technical Problem

Existing lymphatic drainage equipment is difficult to be suitable for the tiny lymphatic vessels on the neck, and it cannot achieve effective drainage of the lymphatic system in the brain, which in turn affects the treatment effect on diseases such as Alzheimer's disease.

Method used

A lymphatic drainage device is designed, including an anti-blocking stent, a drainage tube and an implantable pump. The anti-blocking stent is used to support the biological tissue of the neck and form a collection cavity to collect lymph fluid; the drainage tube is divided into multiple channels through the inner groove section and the partition, which improves the channel area and stability of the drainage tube; the implantable pump realizes continuous drainage and negative pressure regulation of the lymph fluid through a one-way peristaltic pump and pressure receptor.

Benefits of technology

Continuous and constant drainage of neck lymph fluid is achieved, improving the collection efficiency of lymph fluid and the reliability of drainage devices, and has the potential to play a role in slowing down or preventing the progress of Alzheimer's disease.

Abstract

The invention relates to a lymphatic drainage device. The lymphatic drainage device comprises an anti-blocking support, a collecting cavity is formed in the anti-blocking support, the anti-blocking support is used for supporting biological tissue on the periphery of a to-be-drained position so as to maintain the shape of the collecting cavity, and the collecting cavity is used for collecting lymph generated by lymphatic tissue on the periphery of the to-be-drained position; the two ends of the drainage tube are an inlet end and an outlet end, the inlet end is used for guiding the lymph into the drainage tube, the outlet end is used for guiding the lymph out of the drainage tube, and the inlet end extends into the collecting cavity; the implantable pump is connected to the drainage tube and is used for pumping the lymph in the collecting cavity from the inlet end of the drainage tube and pumping the lymph out from the outlet end of the drainage tube. By designing the lymph drainage device with the function of automatically adjusting negative pressure suction, continuous drainage of neck lymph is achieved.
