Implantable liquid transfer device and liquid transfer control system

Abstract

The invention discloses an implantable liquid transfer device and a liquid transfer control system. The implantable liquid transfer device comprises a pump body, control valves, a liquid inlet pipe and a liquid outlet pipe, the control valves comprise the first control valve and the second control valve, one end of the liquid inlet pipe is connected with one end of the pump body, and one end of the liquid outlet pipe is connected with the other end of the pump body; the pump body is used for driving body fluid to flow from the liquid inlet pipe to the liquid outlet pipe, a plurality of branch pipes are arranged at the other end of the liquid outlet pipe, the first control valve is arranged on the liquid inlet pipe, the second control valve is arranged on the liquid outlet pipe, the second control valve is a multi-way valve and used for controlling the liquid outlet pipe to be communicated with the branch pipes, and the branch pipes are arranged at different tissue positions respectively. The implantable liquid transfer device avoids infection caused by repeated puncture, and is better in universality for ascites patients; moreover, the design of the plurality of branch pipes can be used for liquid transfer, drug administration treatment or sampling detection, and drainage of liquid containing inflammatory factors and deterioration of tumors and the like to the outside of a body.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an implanted liquid transfer device and a liquid transfer control system. Background technique [0002] Edema is a pathological process in which excessive body fluid accumulates in interstitial spaces or body cavities, such as cardiac edema induced by heart failure, renal edema caused by primary renal disease, and hepatic edema caused by abnormal accumulation of body fluid caused by liver disease , Pulmonary edema with excess fluid accumulation in the lung interstitium and / or overflow into the alveoli, Cerebral edema with increased brain volume and volume due to increased fluid content in the brain tissue. The main causes of tissue edema include increased capillary blood pressure, decreased plasma colloid osmotic pressure, increased capillary permeability, and blocked lymphatic return. Tissue edema can cause certain organ dysfunction, such as gastrointestinal mucosal ede...
