Description
Technical Field
[0001] The invention relates to a monitoring box switch control module and a blood separator based on the monitoring box, belonging to the technical field of blood separators. Background Art
[0002] A blood separator is a device used to separate different components in blood, usually used in the medical field and laboratory research. Through rotating centrifugal force or other separation methods, the blood separator can separate blood into different components such as red blood cells, plasma, platelets, etc., and facilitate various tests, treatments or research. The blood separator plays an important role in clinical diagnosis, blood transfusion, blood disease treatment and other fields;
[0003] At present, blood separators mostly use monitoring boxes to shunt blood, and the monitoring boxes use switch control modules to realize internal circuit disconnection and pressure detection. During the long-term use of blood separators, people have found that the current switch control modules have the following problems:
[0004] 1. The switch control module is integrated with a precision pressure sensor and an actuating valve. For the convenience of detection, the precision pressure sensor protrudes from the surface of the switch control module. The actuating valve and the precision pressure sensor may be damaged and fail if they are pressed by external force or slightly collided. The current protective measure is to manually lay a rubber pad on the switch control module, but the rubber pad is only used for plane protection. The precision pressure sensor and the actuating valve still protrude from the surface of the switch control module. When the switch module is impacted or pressed by external force, the actuating valve and the precision pressure sensor are still likely to be impacted, and the protective effect of the rubber pad is not good;

[0037] The air source device, the control element, and the air pressure auxiliary module together constitute a pneumatic transmission system.
[0038] The hydraulic station and the hydraulic auxiliary module together constitute a hydraulic transmission system.
[0039] Optionally, a monitoring box switch control module operation method:
[0040] S01: The blood separator is turned on, the control unit is powered on, and the control unit controls the output end of the electromagnetic switch to shrink. The slider loses its limit, and the winding spring drives the reel to rotate. The reel winds up the protective film, and the protective film drives the traction strip and the slider to move toward the end where the reel is located, and the protective film is removed from the detection module.
[0041] S02: The monitoring box is clamped under the pressure block in the clamping module; the manual control unit sends a command to the clamping module, the brake solenoid valve in the clamping module is actuated, the position of the pressure block in the clamping module is locked, the bottom surface of the monitoring box is attached to the upper surface of the shell, and the monitoring box is clamped and positioned.
[0042] S03: The control unit inflates air into the air pressure auxiliary module, the air pressure in the air chamber tube increases, the elastic diaphragm expands outward, the elastic diaphragm drives the pressure sensor to bulge upward on the shell surface, and the pressure sensor is attached to the bottom of the monitoring box.
[0043] The control unit drives the piston in the hydraulic auxiliary module to output outward, the piston drives the actuating valve to move upward, the brake valve protrudes from the shell surface, and the actuating valve fits the bottom surface of the monitoring box; the detection module is in place.
[0044] S04: The control unit detects that the pressure in the pneumatic auxiliary module reaches a high set value and detects that the pressure in the hydraulic auxiliary module reaches a high set value. Further, the control unit sends an action instruction to the pressure sensor and the actuator valve. At this time, the monitoring module enters the detection state; the pressure sensor detects the fluid pressure in the monitoring box, and the actuator valve controls the on and off of the circuit in the monitoring box.
[0045] S05: After the detection is completed, the control unit is manually operated, the brake solenoid valve of the clamping module is powered off, the clamping module pressure block resumes its active state, and the monitoring box is removed.
[0046] S06: The control unit controls the hydraulic auxiliary module, the piston retracts inward, the piston drives the actuating valve to move downward, and the brake valve is recessed in the shell surface.
[0047] The control unit controls the exhaust of the air pressure-assisted module, and the exhaust pipeline is connected to the input end of the pneumatic motor. After the gas is discharged, when the pressure value in the gas warehouse tube reaches the low set value in the control unit, the vacuum pump in the control unit intervenes, and the pressure in the gas warehouse tube becomes negative pressure, and the elastic diaphragm contracts inward, and the elastic diaphragm drives the pressure sensor to sink downward on the shell surface; the actuator valve and pressure sensor are powered off, and the detection module is in standby mode.
[0048] S07: The pneumatic motor drives the reel to rotate, and the reel is wound around the traction rope. The traction rope drives the slider and the traction bar to slide toward the end where the pneumatic motor is located. The traction bar pulls the protective film to cover the detection module to protect the detection module. When the slider is pulled over the position of the electromagnetic switch, the pneumatic motor stops rotating due to exhaustion of gas, and the output end of the electromagnetic switch pops up to limit the slider to prevent the protective film from rebounding. The protective module is in place. The gas exhausted by the pneumatic motor is introduced into the shell of the detection module through the pipeline to enhance the air convection inside the shell and strengthen the heat dissipation of the detection module.
[0049] Compared with the prior art, the present invention has the following beneficial effects:
[0050] The monitoring box switch control module and the blood separator based on the monitoring box described in the present invention respectively drive the actuator valve and the precision pressure sensor to extend and retract by arranging a hydraulic transmission component and a pneumatic transmission component in the detection module. When the module is contracted, the actuator valve and the precision pressure sensor can be prevented from protruding from the plane, which greatly reduces the probability of the actuator valve and the precision pressure sensor being impacted by external force and improves the reliability of protection. When the module is extended, the actuator valve and the precision pressure sensor are in direct contact with the monitoring box, which improves the action accuracy and detection accuracy of the switch control module.
