It will be apparent to those skilled in the art that the foregoing is in the specific sense of this application.

The application provides a liquid storage device, which can be used for a sample analyzer, is used for storing liquid and provides corresponding liquid for a relevant liquid pipeline in the sample analyzer. In the whole workflow of the sample analyzer, a plurality of links need to use liquid to perform corresponding working treatment. Illustratively, the liquid may include buffers, hemolysis agents, reagents, and the like.

The liquid storage device provided by the application is simple in structure, and can be used for replacing liquid on the premise of not interrupting and interfering with the test in the process of testing the sample analyzer, so that the detection time is saved, and the working efficiency of the sample analyzer is improved; in addition, whether the liquid in the liquid storage tank reaches the upper limit or not is sensed by arranging two sensors, and even if the middle sensor fails, whether the liquid is full or not can be sensed by the other sensor.

Referring to fig. 1, fig. 1 is a schematic structural diagram of an embodiment of a liquid storage device provided in the present application, and the liquid storage device 10 includes: a liquid storage tank 11, a first sensor 12, a second sensor 13 and a third sensor 14 which are arranged in the liquid storage tank 11.

The liquid storage tank 11 is used for storing liquid. The liquid may include buffers, hemolytic agents, reagents, and the like. The liquid storage tank 11 includes a bottom wall (shown in fig. 1 but not numbered), side walls (shown in fig. 1 but not numbered), and a top cover (shown in fig. 1 but not numbered). The side wall is connected with the bottom wall and the top cover to form a containing space for storing liquid. The liquid storage tank 11 can be used for providing corresponding liquid for relevant liquid pipelines in the sample analyzer, avoiding directly providing liquid for the sample analyzer through a liquid pump, reducing the generation of tiny bubbles, and greatly reducing the interference of the tiny bubbles on measurement.

In the embodiment shown in fig. 1, the bottom wall of the liquid storage tank 11 is provided with a liquid outlet (not shown in the drawing) for discharging the liquid in the liquid storage tank 11, and the top cover of the liquid storage tank 11 is provided with a liquid inlet (not shown in the drawing) for filling the liquid in the liquid storage tank 11. That is, the liquid inlet is provided at the upper portion of the liquid storage tank 11, and the liquid outlet is provided at the bottom of the liquid storage tank 11, in such a manner that the filling of the liquid storage tank 11 and the discharge of the liquid in the liquid storage tank 11 are facilitated. In other embodiments, the liquid outlet and liquid inlet may also be provided in the side wall of the liquid storage tank 11.

The first sensor 12, the second sensor 13, and the third sensor 14 are for sensing the volume of the liquid in the liquid storage tank 11. The first inductor 12 is a first distance from the bottom wall of the liquid storage tank 11, the second inductor 13 is a second distance from the bottom wall of the liquid storage tank 11, and the third inductor 14 is a third distance from the bottom wall of the liquid storage tank 11, wherein the second distance is larger than the first distance, and the second distance is smaller than the third distance. That is, the first inductor 12 is located in the tank 11 near the bottom wall of the tank 11, the third inductor 14 is located in the tank 11 near the top cover, and the second inductor 13 is located between the first inductor 12 and the third inductor 14.

The first sensor 12 is used for sensing whether the liquid in the liquid storage tank 11 is insufficient. If the first sensor 12 is triggered, the shortage of the liquid in the liquid storage tank 11 can be confirmed, at this time, the number of tests of the sample analyzer can be limited or the sample analyzer can be instructed to stop working, the sample analyzer is prevented from detecting inaccuracy, and the user can be reminded to replace the liquid, such as reagent replacement, and the like. The distance between the first sensor 12 and the bottom wall of the liquid storage tank 11 may be determined according to the number of samples that can be detected when the liquid is at the lower limit, for example, the position of the first sensor 12 is set at a position where the liquid level can measure 3 samples.

The second sensor 13 senses whether the liquid in the liquid storage tank 11 has reached the upper limit, and when the liquid level reaches the position of the second sensor 13, that is, when the second sensor 13 is triggered, it is confirmed that the liquid in the liquid storage tank 11 has reached the upper limit, and therefore, the filling of the liquid storage tank 11 can be stopped based on the trigger signal of the second sensor 13. In this way, whether the liquid amount in the liquid storage tank 11 reaches the upper limit can be automatically sensed, the liquid is prevented from overflowing from the liquid storage tank 11, and the instrument is prevented from being damaged.

The third sensor 14 is also disposed in the liquid storage tank 11, and the third sensor 14 is located near the top cover of the liquid storage tank 11 and is also used for sensing whether the liquid in the liquid storage tank 11 reaches the upper limit. When the second sensor 13 fails, the third sensor 14 can be used as the final insurance, and when the third sensor 14 is triggered, the liquid filling in the liquid storage tank 11 is immediately stopped, the warning of the failure of the second sensor 12 is sent, and the user can replace the second sensor 13 in time after receiving the warning.

The distance between the third inductor 14 and the second inductor 13 is smaller than the distance between the second inductor 13 and the first inductor 12. That is, the distance between the third sensor 14 and the second sensor 13 is short, so that the third sensor 14 is designed as a safety redundancy, and the safety of the liquid storage tank 11 is improved.

In the embodiment shown in fig. 1, the first sensor 12, the second sensor 13 and the third sensor 14 may be floats, and when the first sensor 12 is not immersed in the liquid storage tank 11, the first sensor 12 is triggered, and it may be determined that the remaining amount of the liquid in the liquid storage tank 11 is insufficient. When the second and third sensors 13 and 14 are immersed in the liquid storage tank 11, it can be confirmed that the liquid in the liquid storage tank 11 has reached the upper limit. In other embodiments, the first sensor 12, the second sensor 13, and the third sensor 14 may also be other sensors, such as photoelectric sensors, and the like.

Further, the liquid storage device 10 may further include a liquid replenishing portion (not shown) connected to the liquid storage tank 11 for replenishing the liquid to the liquid storage tank 11 or stopping replenishing the liquid.

The fluid replacement part may include a fluid replacement tank 30 and a driving member 20 connected to the fluid replacement tank 30, and the driving member 20 is used to drive the fluid in the fluid replacement tank 30 into the fluid reservoir tank 11. In the embodiment shown in fig. 1, the driving member 20 is a liquid pump, one end of which is connected to the liquid storage tank 11, and the other end of which is connected to the liquid replenishment tank 30. In other embodiments, the driving member 20 may be a positive pressure driving member or a negative pressure driving member.

Further, the liquid storage device 10 may further include a controller (not shown) connected to the first sensor 12, the second sensor 13, the third sensor 14, and the driving member 20.

When the liquid storage tank 11 is filled, the liquid level in the liquid storage tank 11 gradually rises, and after the trigger signal of the second sensor 13 is received by the controller, the driving piece 20 is controlled to stop filling; if the second sensor 13 fails, the third sensor 14 is used as the last safety, and if the liquid level continues to rise, after the third sensor 14 is triggered, the controller receives the trigger signal of the third sensor 14 and then controls the driving member 20 to stop filling the tank, and a reminding message can be sent to remind the user to replace the second sensor 13 in time. When the first sensor 12 is triggered, that is, after the controller receives the trigger signal of the first sensor 12, the shortage of the liquid in the liquid storage tank 11 can be confirmed, and at this time, the sample analyzer can limit or stop detecting the number of tests, so as to avoid inaccurate detection and prompt a user to replace the used liquid. By the mode, liquid can be replaced timely on the premise of not interrupting or interfering with testing in the testing process, time is saved, and the detection efficiency of the sample analyzer is improved. And the upper limit of the liquid in the liquid storage tank 11 is sensed by designing two inductors, namely, the third inductor 14 is used as a safety redundancy design, even if the second inductor 13 fails, the driving piece 20 can be guaranteed to be closed timely, the liquid is prevented from overflowing from the liquid storage tank 11, and the sample analyzer is prevented from being damaged, so that the safety and the reliability of the sample analyzer are improved.

Optionally, a fixing rod 15 is disposed in the liquid storage tank 11, and the first sensor 11, the second sensor 12 and the third sensor 13 are fixed on the fixing rod 15, so that the sensors are fixed through the fixing rod 15, the fixing structure of the sensors is simple, and the assembly of the sensors is facilitated. In other embodiments, three sensors may be fixed in the side wall of the liquid storage tank 11, so that the structure of the liquid storage device 10 can be simplified, and the hardware cost can be saved.

Alternatively, the third inductor 14, the second inductor 13 and the first inductor 12 are arranged side by side in the vertical direction. For example, a fixing rod 15 extending in the vertical direction is provided in the liquid storage tank 11, and the first sensor 12, the second sensor 13, and the third sensor 14 are all fixed to the fixing rod 15. The fixing mode can facilitate the installation and the disassembly of the inductor.

Alternatively, as shown in fig. 1, a fixing rod 15 is fixed to the top cover of the liquid storage tank 11, and one end of the fixing rod 15 away from the top cover of the liquid storage tank 11 is spaced from the bottom wall of the liquid storage tank 11. Thus, the fixing rod 15 does not interfere with the liquid outlet, and the liquid can be discharged more smoothly.

As shown in fig. 1, the liquid storage device 10 further includes a liquid inlet 16, the liquid inlet 16 is disposed at the liquid inlet, a diversion connector 17 is inserted at one end of the liquid inlet 16 in the liquid storage tank 11, and an outlet of the diversion connector 17 is disposed towards a side wall of the liquid storage tank 11.

The diversion connector 17 can be L-shaped, arc-shaped and the like, and only the requirement that the outlet of the diversion connector 17 faces the side wall of the liquid storage tank 11 is met. In the prior art, the solution entering from the liquid inlet of the liquid storage tank 11 is directly injected into the liquid storage tank 11 vertically, but in this case, tiny bubbles are generated when the liquid is conveyed, for example, the solution with the bubbles is directly introduced into the measuring system, and the tiny bubbles in the liquid can interfere with measurement. In this embodiment, the liquid is drained to the side wall of the liquid storage tank 11 through the diversion connector 17, so that the liquid slides into the liquid storage tank 11 along the wall surface of the side wall, bubbles in the liquid entering the liquid storage tank 11 float upwards for a relatively sufficient time, the bubble content of the liquid in the liquid storage tank 11 is reduced, and the detection accuracy of the sample analyzer is improved.

Further, as shown in fig. 1, the liquid storage device 10 may further include a pressure balancer 18, where the pressure balancer 18 is disposed on the liquid storage tank 11, for adjusting the air pressure in the liquid storage tank 11. The reservoir 10 may also include a three-way connection 181, a first air filter 182, and a second air filter 183.

Specifically, a first end of the three-way joint 181 is connected to an air inlet of the pressure balancer 18 through a pipeline, a second end of the three-way joint 181 is connected to the first air filter 182 through a pipeline, and a third end of the three-way joint 181 is connected to the second air filter 183 through a pipeline. The first air filter 182 and the second air filter 183 filter dust and foreign substances in the atmosphere, respectively, so that the liquid stored in the liquid storage tank 11 is not easily deteriorated.

Unlike the prior art, the liquid in the liquid replenishing tank 30 in the above embodiment does not directly enter the measurement system of the sample analyzer, but temporarily stores the liquid through the liquid storage tank 11, so that tiny bubbles in the liquid can be reduced from entering the measurement system of the sample analyzer, and interference of the tiny bubbles on the measurement of the sample analyzer can be reduced; the first sensor 12 senses whether the liquid in the liquid storage tank 11 is insufficient, so that the liquid can be replaced on the premise that the sample analyzer is not interrupted or the test is not interfered, the test time of the sample analyzer is saved, and the working efficiency of the sample analyzer is improved; by adopting the third sensor 14 as a safety redundant design, even when the second sensor 13 fails, the liquid can still be stopped to be filled into the liquid storage tank 11 in time, so that the liquid is prevented from overflowing from the liquid storage tank 11, and the sample analyzer is prevented from being damaged; when the liquid storage tank 11 is filled, liquid slides into the liquid storage tank 11 along the wall surface of the side wall of the liquid storage tank 11, so that bubbles in the liquid flowing into the liquid storage tank 11 float upwards for a relatively sufficient time, the bubble content of the liquid in the liquid storage tank 11 is reduced, and the test accuracy of the sample analyzer is improved.
