firstly, a blood introducing port 2-2-1 of a first guiding tube 2-2 is connected with an external blood guiding tube (for example, in the hemodialysis process, when the patient blood is connected with a hemodialysis machine, one guiding tube is separated and communicated with a blood introducing port 2-2-1 of the blood coagulation time measuring device of the utility model), then a first computer control center controls a first switch 2-3 to be opened, so that the target blood flows into a stirring container 2-1 through the blood introducing port 2-2-1 until the bottom of a stirring rod 2-4 is submerged (generally, a stirring blade 2-4-1 can be selected to be arranged at the bottom of the stirring rod, and the stirring blade 2-4-1 can be submerged), at the moment, the required target blood volume can be reduced by controlling the distance between the bottom of the stirring rod 2-4 and the bottom of the stirring container 2-1, for example, 1 ml of blood is injected into the stirring vessel 2-1; the fifth switch is synchronously controlled by the first computer control center to open the heating wire 6-1 for heating, so that the temperature of the stirring container 2-1 is always kept at a constant temperature of about 37 ℃, and the constant temperature state is always kept in the use process of the whole blood coagulation time measuring device.
In the second step, the second switch 3-3 is controlled by the first computer control center to open, the coagulant in the coagulant bottle 3-1 flows into the stirring container 2-1, and when the coagulant flow into the stirring container 2-1 reaches the predetermined dosage, the first computer control center controls the second switch 3-3 to close.
Thirdly, the first computer control center controls the rotating device 2-5 to drive the stirring rod 2-4 to rotate (preferably, the stirring rod rotates automatically or rotates along the inner edge of the stirring container 2-1), at the moment, the stirring blade 2-4-1 rotates together, meanwhile, the rotating sensor monitors the rotating speed of the stirring rod 2-4 and synchronously feeds monitoring information back to the first computer control center, the first computer control center processes and judges that the target blood reaches the coagulation effect and obtains the coagulation time (for example, when the normal target blood is in a non-coagulation state, the rotating speed of the stirring rod 2-4 is A circles per second, when the target blood is gradually coagulated, namely the rotating speed of the stirring rod 2-4 is reduced to B circles per second, at the moment, the target blood is slightly coagulated but still in a liquid state, but the blood can be determined to be in a coagulation state, where a is about B, a and B may be preset), and then the first computer control center controls the rotating device 2-5 to stop driving the stirring rod 2-4 to rotate, and feeds the blood coagulation time back to the user through the first display screen.
The fourth step, scheme one: the first computer control center controls the fourth switch 5-3 to be opened, waste blood which is in the stirring container 2-1 and has finished the blood coagulation time measurement flows into the waste liquid collecting bottle 5-1 through the fourth guide tube 5-2, and after the waste blood is exhausted, the first computer control center controls the fourth switch 5-3 to be closed; then the first computer control center controls the third switch 4-3 to be opened, the cleaning agent in the cleaning agent bottle 4-1 flows into the stirring container 2-1, the stirring rod 2-4 and the stirring blade 2-4-1 are cleaned, in order to ensure or improve the cleaning effect, the third step of operation can be selected to ensure that the stirring rod 2-4 and the stirring blade 2-4-1 rotate, and the cleaning force is increased;
after cleaning, the first computer control center controls the fourth switch 5-3 to be opened, the cleaned waste liquid in the stirring container 2-1 flows into the waste liquid collecting bottle 5-1 through the fourth guide pipe 5-2, and after the waste liquid is exhausted, the first computer control center controls the fourth switch 5-3 to be closed; in order to ensure the cleaning effect, the cleaning operation and the waste discharge operation in the step can be repeated for several times.
In the step, the waste blood is discharged and then cleaned, so that the condition that the inner side wall of the stirring container 2-1 is polluted by the waste blood along with the injection of the cleaning agent can be prevented, the cleaning area is smaller, and the cleaning agent is saved.
Or scheme two;
