Abstract

The invention relates to a blood purification auxiliary device, in particular to an automatic device for solving the problem of unsmooth blood guide in blood purification. The automatic device comprises a mounting plate, a three-way device and a normal saline placement device, wherein the three-way device is mounted on one side of the mounting plate, and the normal saline placement device is arranged at the top of the three-way device. According to the automatic device for solving the problem of unsmooth blood guide in blood purification, an intubation tube of a valve tube is inserted into a normal saline bag, pressure in the tube of a blood purification device is high when a catheter is attached to a wall, normal saline is injected into a connecting tube, proper blood flow is ensured, continuous blood purification effects are improved, a solenoid valve in the valve tube is controlled to work by a solenoid valve control module, the normal saline is automatically injected, working automation is realized, and weight digital signals acquired by a weight acquisition module are converted into flow information by a flow algorithm module.

Description

technical field [0001] The invention relates to an auxiliary device for blood purification, in particular to an automatic device for solving the problem of blood purification and drainage. Background technique [0002] Continuous blood purification technology can slowly, continuously and stably remove various toxins, inflammatory mediators and excess water in the patient's body, and regulate the internal environment of the human body. It has been widely used in the treatment of various critically ill patients. During the continuous treatment process, the normal operation of the bedside blood purification device is the key to the smooth progress of the treatment. The monitoring system of the blood purification device can ensure the safety of the patient during the treatment process. When the patient's treatment process is in an abnormal state, the machine will alert the medical staff through an alarm. However, the frequent alarms of the machine interrupt the patient's treatm...
