Description

Technical Field

[0001] The invention belongs to the technical field of medical device products, and in particular relates to a reagent needle cleaning device integrated with a waste liquid collection fluid. Background Art

[0002] The traditional reagent needle cleaning tank and waste liquid collection body are two components. The problem of the reagent needle cleaning tank is that the waste liquid sticks to the wall, resulting in a high instrument carryover contamination rate, or the structure is complex and inconvenient to disassemble and maintain. A separate waste liquid collection body will increase the cost of the pipeline. At the same time, the increase in liquid accumulation in the pipeline will increase the instrument carryover contamination rate. At the same time, traditional waste liquid is discharged from the needle washing tank by its own gravity, and then connected to the drainage power system after merging with other waste liquid pipelines. This makes the drainage suction not high and reduces the drainage efficiency. Summary of the invention

[0003] In order to solve the technical problems existing in the prior art, the present invention provides a reagent needle cleaning device integrating waste liquid and confluence, including a cleaning tank, a cleaning core and a liquid level sensor bracket. The cleaning tank is the base of the entire device, and other components are installed on the cleaning tank. The confluence tank is installed on the side of the cleaning tank, and the cleaning core is installed in the mounting hole on the upper end surface of the cleaning tank. Rubber rings are installed on the upper and lower grooves of the cleaning core. Joint 1 is installed on the threaded hole at the upper end of the side of the cleaning tank. Joint 1 is connected to the liquid inlet pipe of the cleaning tank. The cleaning core cooperates with the upper and lower sealing rubber rings to form an annular liquid cavity in the cleaning tank. When water enters joint 1, the cleaning core flushes the outer wall of the reagent needle from six directions, and at the same time, the upper end of the reagent needle is drained to clean the inner wall of the reagent needle. During cleaning, the drainage power system provides suction to accelerate the removal of waste liquid. The polytetrafluoroethylene coating on the inner wall of the cleaning tank reduces the waste liquid hanging on the wall.

[0004] The liquid level sensor bracket is installed on the confluence pool on the side of the cleaning pool and is connected with a countersunk screw. The liquid level sensor is installed on the threaded hole at the bottom of the liquid level sensor bracket, the plug is installed on the threaded hole at the upper end of the side wall of the confluence pool, and the second connector is installed on the threaded hole at the lower end of the side wall of the confluence pool to connect the waste liquid pipe inside the machine. A liquid level switch is installed inside the confluence pool to collect signals. When waste liquid enters the confluence body, the negative pressure of the discharge will be increased for discharge. The internal waste liquid enters the confluence pool through the second connector and is discharged through the internal drainage hole at the same time. When the waste liquid flows into the confluence pool, the waste liquid will drag the float of the liquid level sensor to float up. After the liquid level rises and the liquid level sensor triggers a signal, the drainage power system will increase the negative pressure for drainage. At the same time, if the waste liquid flow is too large, the drainage hole will overflow after the liquid level rises, thereby accelerating the drainage rate. The bottom of the cleaning pool is connected with a third connector, and the third connector is connected to the drainage power system. Whenever the needle is washed or the liquid is discharged, the power system provides suction to help drain the liquid.

[0005] The working steps are as follows: the reagent needle enters the cleaning tank from top to bottom at the center of the cleaning tank opening above the cleaning tank, and the cleaning liquid enters the cleaning tank at the same time. There are six water columns pointing to the center of the circle in the cleaning core to clean the reagent needle. The drainage power system provides negative pressure to draw away the cleaning liquid. The machine waste liquid enters the confluence pool, flows into the cleaning needle channel in the cleaning tank through the waste liquid port, and flows into the waste liquid discharge pipe through connector 2 for drainage.

[0006] Beneficial effects:

[0007] 1. The present invention integrates two components, a reagent needle cleaning tank and a waste liquid confluence, so that the end of the reagent needle cleaning tank is directly connected to the drainage power system, thereby increasing the negative pressure of the needle washing tank. The increased negative pressure can increase the flow rate of the cleaning liquid, thereby improving the efficiency and effect of the needle washing. At the same time, the inner wall of the cleaning tank is sprayed with a polytetrafluoroethylene coating to cooperate with the large suction force to reduce the waste liquid from hanging on the wall and reduce the carryover pollution rate. At the same time, the entire structure only needs one drainage pipe and two liquid inlet pipes, with simple piping and simple and convenient maintenance.

[0008] 2. The present invention cleans the reagent needle through the annular cleaning port of the cleaning core, and cooperates with the polytetrafluoroethylene coating on the inner wall of the cleaning tank to reduce the waste liquid sticking to the wall. At the same time, the direct connection to the drainage power system increases the negative pressure, so that the contamination rate of the cleaning needle system is less than or equal to 0.025%. At the same time, the reagent needle cleaning tank and the waste liquid confluence tank are integrated to simplify the component structure, reduce the pipeline connection between the two, reduce the difficulty of assembly, reduce the manufacturing and maintenance costs, and facilitate popularization and use.

The confluence tank 11 is equipped with a liquid level switch to collect signals. When waste liquid enters the confluence fluid, the negative pressure of the discharge will be increased to discharge the liquid. The internal waste liquid enters the confluence tank 11 through the second connector 4. At the same time, the waste liquid is discharged through the internal drainage hole. When the waste liquid flows into the confluence pool 11, the waste liquid will drag the float of the liquid level sensor 10 to float up. After the liquid level rises and the liquid level sensor 10 triggers a signal, the drainage power system will increase the negative pressure to drain the liquid.
