Clinical hemodialysis device for nephrology department

Abstract

The invention discloses a clinical hemodialysis device for the nephrology department. The clinical hemodialysis device comprises a dialyzer, a liquid inlet of the dialyzer is provided with a connecting tube, and the end, away from the dialyzer, of the connecting tube is connected with a liquid outlet of a material suction pump; a liquid inlet of the material suction pump is provided with a blood drawing tube, a first blood drawing tube liquid inlet of the blood drawing tube is connected to an external needle, a liquid outlet of the dialyzer is provided with a reflux device, a third one-way valve is arranged at a tube opening of the upper end of a tube diverter of the reflux device, a liquid inlet tube is arranged at a tube opening of the lower end of the tube diverter, and a second one-wayvalve is arranged at the junction between the liquid inlet tube and the tube diverter. The clinical hemodialysis device for the nephrology department has a simple structure, the temperature of solutions in a second reflux tube and the liquid inlet tube can be detected, the situation that a patient feels uncomfortable due to too low temperature of blood is avoided, and a blood sample can be extracted through a three-way tube and the tube splitter, so that convenience is provided for detecting the blood sample of the patient, the operation is simple, and the device is convenient to use.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a clinical hemodialysis device for nephrology. Background technique [0002] Hemodialysis is one of the renal replacement therapy methods for patients with acute and chronic renal failure. It drains the blood from the body to the outside of the body, and passes through a dialyzer composed of countless hollow fibers. Inside and outside the hollow fiber, materials are exchanged through diffusion / convection to remove metabolic waste in the body, maintain electrolyte and acid-base balance; at the same time remove excess water in the body, and return the purified blood. The whole process is called hemodialysis. When the existing hemodialysis device transports the blood back to the patient, the temperature is relatively low, which easily causes discomfort to the patient. It cannot be heated when injecting normal saline. When sampling the blood of the patient, additional extract...
