Description

Technical Field

[0001] The utility model relates to the technical field of medical detection, and particularly relates to a multi-channel PSA detection instrument. Background Art

[0002] Prostate cancer accounts for 10% - 20% of all types of cancers in men, and is the most common cancer in men, with a slow progression. In men over 65 years old, the incidence surges. Therefore, prostate cancer is the main cancer threatening the lives of men over 50 years old, ranking second in male mortality in the West. Epidemiological investigations show that with the improvement of living standards, pollution, and the westernization of dietary structures in China, the incidence of prostate cancer is also increasing day by day, which must attract great attention in oncology clinics. PSA detection is widely used to diagnose prostate cancer and is a good tumor marker. Currently, PSA detection is used as an indicator for general surveys of men over 50 years old. When conducting health surveys in community hospitals, the examined personnel are relatively concentrated, and the sampling time is generally within two hours. The detection work needs to be completed in a short time.

[0003] For example, a reagent card detection instrument disclosed in the Chinese patent document with the publication number CN208459396U has a relatively complex PSA detection operation. It needs to rely on a timer for timing. After the timing is up, the reagent is inserted into the slot for inspection. When detecting multiple reagent strips, multiple timers are required for timing, and only one reagent can be detected at a time, which greatly affects the detection efficiency and wastes operation time.

[0030] The reagent card insertion assembly 3 includes 8 slots 31 arranged side by side and a in-place detection member 32 provided at the end of the slots 31. The slots 31 are used for inserting the reagent card 13, that is, one slot 31 corresponds to one detection channel. The in-place detection member 32 is used to detect whether the reagent card 13 is inserted in place. The arrangement direction of the slots 31 is the first direction, and the insertion direction of the reagent card 13 is the second direction;

[0031] There are also 8 data display screens 14 electrically connected to the control module 2 installed on the housing 1. Specifically, the data display screens 14 are arranged in one-to-one correspondence above the slots 31, so that each data display screen 14 can respectively display the test results of the reagent cards 13 on the slots 31 below it.

[0032] The reagent card scanning assembly includes a first sliding mechanism 4, a second sliding mechanism 5 installed on the first sliding mechanism 4, and a scanning head 6 installed on the second sliding mechanism 5.

The first sliding mechanism 4 is installed between the two vertical plates. The first sliding mechanism 4 includes a horizontal axis motor 41, a horizontal axis lead screw 42 and a horizontal moving slider 43. The horizontal axis motor 41 is drivingly connected to the horizontal axis lead screw 42. The horizontal moving slider 43 is slidably arranged on the horizontal axis lead screw 42. The horizontal axis motor 41 drives the horizontal axis lead screw 42 to rotate, thereby driving the horizontal moving slider 43 to move back and forth along the first direction on the horizontal axis lead screw 42, and further driving the scanning head 6 to move back and forth along the first direction. The first sliding mechanism 4 further includes guide rods 44 arranged in parallel on both sides of the horizontal axis lead screw 42.

Inside the housing 1, a reset detection member 12 electrically connected to the control module 2 is arranged corresponding to the starting end of the horizontal moving slider 43, specifically an optoelectronic switch, which is used to detect that the horizontal moving slider 43 is in place after reset, and transmit the in-place information to the control module 2 to control the horizontal moving slider 43 to stop resetting at the starting end.

[0037] In this embodiment, the second sliding mechanism 5 includes a vertical axis motor 51 and a vertical axis lead screw 52 which are drivingly connected. The vertical axis motor 51 is fixedly installed on the horizontal moving slider 43. The scanning head 6 is slidably arranged on the vertical axis lead screw 52. The vertical axis motor 51 drives the vertical axis lead screw 52 to rotate, thereby driving the scanning head 6 to move back and forth along the second direction on the vertical axis lead screw 52. A longitudinal guide rail 8 is arranged along the second direction at the bottom of the horizontal moving slider 43. A vertical moving slider 7 is arranged at the top of the scanning head 6. The vertical moving slider 7 is slidably matched with the longitudinal guide rail 8, so as to improve the guiding accuracy of the scanning head 6 moving back and forth in the second direction.

[0038] The detection process of the present utility model is as follows:

[0039] 1. Turn on the machine, initialize the inside of the control module 2, wait for the touch display screen 10 to display successful handshake, the page of the touch display screen 10 enters the startup page, enter the self-check, detect whether the external devices are working properly, reset each motor, and after everything is normal, the touch display screen 10 enters the system interface.

[0040] 2. Read the NFC card information in the reagent kit, input the item information of this reagent, and apply the item.

[0041] 3. Click the detection button to enter the detection page, use the barcode scanning module 9 to scan the barcode information on the blood sample. After scanning the information, the system will select the corresponding detection channel and prompt to insert the sample reagent card 13. After inserting the reagent card 13, start the detection. If there is no idle detection channel, it will prompt that there is no available detection channel. It is also possible to manually input the sample, select the detection mode, and then click the start detection button to start the detection. After starting the detection, according to the set detection mode, for the standard detection, wait for the timing to end and send the detection signal, and for the immediate detection, directly transmit the detection signal.

[0042] 4. When the control module 2 receives the detection signal, it first determines whether there is another detection channel that is currently performing detection. It queues up and waits until the detection of the other channel ends before proceeding with its own detection. During the detection process, it first checks whether there is a reagent card 13 in the detection channel. If there is no reagent card 13, the detection is stopped. If there is a reagent card 13 in the detection channel, the horizontal axis motor 41 drives the scanning head 6 to move to the position above the detection channel to be detected in the first direction, turns on the LED excitation light and AD detection, then starts the vertical axis motor 51 to drive the scanning head 6 to move in the second direction to scan the reagent card 13, captures the AD values, forms a curve, smooths the curve, substitutes the set parameters to calculate the peak area sizes of C and T values, obtains the CT value, gets the result, displays the result on the touch display screen 10 and stores it in the flash, prints the detection result through the printer, and the detection ends; then waits for the next detection signal response.
