Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a device for detecting the presence or absence of probe cleaning fluid. Background Technology

[0002] Currently, human blood contains proteins and other substances. After prolonged testing, proteins and other substances can accumulate in the blood testing module, clogging it and causing inaccurate test results. In this case, it is necessary to soak the instrument's testing module in probe cleaning solution to remove the deposited substances and ensure the accuracy of the test results.

[0003] Currently, most testing methods, in order to address this issue, require users to soak the instrument's detection modules in probe cleaning solution after a certain period of use, with the software automatically reminding the user. However, most instruments currently place the probe cleaning solution in a test tube positioned within the instrument, and then use a sampling needle to draw the solution into each detection module for soaking. Existing instruments essentially assume the probe cleaning solution is already in place, relying solely on visual inspection. The instrument does not detect whether the user has placed the probe cleaning solution or whether the blood sample has been removed. This can lead to ineffective soaking of the detection modules, or even the direct use of blood as probe cleaning solution, causing instrument malfunction. Utility Model Content

[0004] The purpose of this invention is to provide a device for detecting the presence or absence of probe cleaning fluid, which aims to solve the problem that conventional instruments cannot detect whether the user has placed probe cleaning fluid, and can only rely on manual visual inspection, which prevents the instrument from being effectively soaked and affects the instrument's performance.

[0005] To achieve the above objectives, this utility model provides a device for detecting the presence or absence of probe cleaning fluid, comprising a sampling mechanism and a detection module. The detection module is disposed on one side of the sampling mechanism and includes a photocell receiver, an LED emitter, and a cup. The cup is disposed on one side of the sampling mechanism, and the photocell receiver is mounted on one side of the cup, with the photocell receiver mounted on the side of the cup away from the LED emitter. The sampling mechanism includes a cable chain, a longitudinal motor, a transverse verification optocoupler baffle, a belt, a sampling needle, a transverse reset optocoupler, a transverse reset optocoupler baffle, a transverse verification optocoupler, and a transverse motor. The system includes a mounting plate, which is disposed on one side of the cable chain. The longitudinal motor is fixedly connected to the cable chain and located on one side of the cable chain. The transverse reset optocoupler baffle is fixedly connected to the mounting plate and located near the longitudinal motor. The sampling needle is disposed on one side of the transverse reset optocoupler baffle. The transverse motor is fixedly connected to the mounting plate and located on one side of the mounting plate. The belt is sleeved on the outside of the transverse motor. The transverse verification optocoupler is fixedly connected to the mounting plate and located on one side of the mounting plate. The transverse reset optocoupler is fixedly connected to the mounting plate and located near the detection module.

[0006] The cable chain includes a cable chain body and a connector. The cable chain body is disposed on the top of the mounting plate. The connector is fixedly connected to the cable chain body and to the belt, and is located on one side of the cable chain body.

[0007] The horizontal motor includes a motor body and a drive wheel. The motor body is fixedly connected to the mounting plate and is located on one side of the mounting plate. The drive wheel is fixedly connected to the output end of the motor body and is located on the side of the motor body away from the mounting plate.

[0008] The sampling needle includes a sampling needle body and a connecting part. The connecting part is fixedly connected to the output end of the longitudinal motor and is located on one side of the longitudinal motor. The sampling needle body is detachably connected to the housing of the connecting part and is located on one side of the connecting part.

[0009] The sampling mechanism further includes a guide rod, which is fixedly connected to the mounting plate and passes through the connector.

[0010] This invention relates to a device for detecting the presence or absence of probe cleaning fluid. The sampling needle is used to draw in the probe cleaning fluid and place it into a transparent liquid within a container. The probe cleaning fluid and the transparent liquid are mixed thoroughly. A mounting plate provides installation and support for the longitudinal motor, the lateral verification optocoupler baffle, and the lateral reset optocoupler baffle. The lateral motor drives the belt to pull the cable chain, thereby moving the sampling needle laterally. The lateral verification optocoupler baffle is used to precisely position the sampling needle within the container. The lateral reset optocoupler is used to reset the sampling needle to its initial position. The lateral reset optocoupler baffle blocks the lateral verification optocoupler during the sampling needle's reset, thus detecting the initial position. The lateral verification optocoupler is used to detect the position of the sampling needle within the container. The longitudinal motor drives the sampling needle. The probe cleaning solution is placed into the transparent liquid inside the cup. The LED emitter irradiates the complex solution inside the cup with monochromatic light of 540nm wavelength, and the transmitted light is received by the photocell receiver on the other side. The received light intensity signal is amplified and converted into a voltage signal. Different liquids are added to the cup, and the voltage generated by the transmitted light intensity of different mixtures is compared to determine whether the solution in the cup is the target liquid. By comparing the voltage of the transparent liquid with the voltage of the probe cleaning solution, the presence of other non-transparent substances is detected. The voltage of the empty cup with the voltage of the probe cleaning solution is also compared to detect the presence of the probe cleaning solution. This avoids the phenomenon of blood being mistaken for probe cleaning solution and soaking the instrument, which can lead to instrument malfunction. It also solves the problem of forgetting to add probe cleaning solution, resulting in ineffective soaking and inaccurate test results, thus improving the reliability and accuracy of the instrument. No manual visual inspection is required, reducing workload and increasing efficiency. It also solves the problem that conventional instruments cannot detect whether the user has added probe cleaning solution, requiring manual visual inspection, which results in ineffective soaking and affects instrument performance.
