Description

Technical Field

[0001] The present invention relates to the technical field of urinary examination, and in particular to a multi-item auxiliary detection device and a detection method for urinary examination. Background Art

[0002] Urinary examination can help doctors understand the patient's urinary system problems in detail, such as urinary tract infection, urinary tract stones, prostatitis, etc., so that medical staff can formulate a reasonable treatment process for patients. At the same time, regular urinary examination can also help residents prevent diseases. In the process of urinary tract examination, a urine analyzer is needed;

[0003] When the urine analyzer is working, the patient's urine needs to be stuck on the test paper, and then the test paper is placed in the urine analyzer. Through the detection of the urine analyzer, urine specific gravity, urine protein, urine pH, urine bilirubin and urine nitrite and other values ​​can be detected. The urine analyzer is a device that can realize multi-item detection;

[0004] For example, the automatic urine analyzer with publication number CN109342754B includes a base, and a strip feeding mechanism, a sample loading mechanism, a sample turntable mechanism, and a paper strip detection mechanism installed on the base; the sample loading mechanism and the paper strip detection mechanism are arranged above the proximal end of the strip feeding mechanism, and the sample turntable mechanism is arranged on one side of the strip feeding mechanism; a paper strip correction mechanism is arranged laterally of the strip feeding mechanism, and the paper strip correction mechanism includes a correction frame, a slide mechanism arranged on the correction frame and pointing to the conveying panel, a correction push plate fixed to the slider of the slide mechanism and capable of reciprocating relative to the conveying panel, and a limit sensing mechanism fixed to one side of the correction frame. This automatic urine analyzer can automatically correct the test strips, thus overcoming the problem of the existing urine analyzer having uneven arrangement of the test strips that affects the instrument detection during operation;

[0005] There is also a fully automatic urine analyzer with publication number CN103823074B, in which the strip feeding mechanism includes a driving motor and a conveying device, and the strip feeding mechanism also includes a bottom plate arranged above the conveying device, and the test strip box is a hollow cavity structure with an open lower end, and the test strip box is arranged on the bottom plate, and the test strips are stacked on the bottom plate in sequence with the front side facing up, and a push block entrance is provided at the bottom of the front wall of the test strip box, and a test strip outlet is also provided at the bottom of the rear wall of the test strip box, and the height of the test strip outlet is greater than the height of the test strip and less than 2 times the height of the test strip; a push block is provided on the conveying device, and the push block passes through the bottom plate and can move forward and backward along the bottom plate, and the highest point of the push block is lower than the highest point of the test strip. In this urine analyzer, the height of the test strip outlet is 1.5 times the height of the test strip, and only one test strip can be pushed out at a time, so as to avoid the situation where the adjacent test strip is brought out of the test strip box when the bottom test strip is pushed, and the lower test strip cannot be added with the sample, and the strip selection is wrong;

[0006] And a urine analyzer with publication number CN117007829B and a method of using the same, comprising an analyzer body, wherein a test strip tray, a conveying unit, an adjustment unit, a correction unit and a detection unit are arranged in the analyzer body. The urine analyzer, by adding a correction unit and an adjustment unit, calculates the tilt angle value of the test strip through the correction unit before collecting and analyzing, and adjusts the angle of the test strip according to the tilt angle value by the adjustment unit, so that the tilt angle of the test strip is compensated and corrected, thereby avoiding the problem that the test strip is tilted relative to the scanning path, causing part of the test strip to be out of the scanning area, resulting in the missing or invalid urine test analysis results, and also reduces the amount of calculation for segmenting and extracting the color blocks on the test strip, thereby speeding up the analysis;

[0007] During use, medical personnel need to place the test paper with urine on the instrument, but the device in the above application does not have a good structure for quickly limiting the test paper. As a result, the test paper may fly away during the detection process, which will affect the detection process. At the same time, the device needs to be disinfected and wiped between each detection, but the device in the above application does not have a self-disinfection function, which will affect the accuracy of the test results and bring unnecessary trouble to the operator and medical personnel in subsequent steps.

[0008] In view of the above problems, it is urgent to carry out innovative design based on the original urinary auxiliary examination device. Summary of the invention

[0025] Compared with the prior art, the beneficial effects of the present invention are as follows: the multi-item auxiliary detection device and detection method for urology adopt a new structural design, so that when the operator places the test paper on the placement plate, the pressing plate can work, and the pressing plate presses the test paper, so that the test paper will not be separated when being detected, thereby ensuring the normal progress of the detection. At the same time, through the material box, material storage airbag and nozzle, the device has a self-disinfecting structure, thereby ensuring the accuracy of each detection. The specific contents are as follows:

[0026] The multi-item auxiliary detection device for urology, when working, after the test paper is placed on the placement board, the placement frame moves to the right inside the urine analyzer, the test paper enters the urine analyzer and is tested and analyzed, and then the medical record sheet can be printed, and the operation process is quick and convenient;

[0027] Furthermore, when the placement plate inside the placement frame is located outside the urine analyzer, the movable rod is in a state of being pushed by the push block, and the connecting spring is in a squeezed state at this time.

[0028] The multi-item auxiliary detection device for urology, when the placement plate inside the placement frame is located outside the urine analyzer, the left side of the placement frame is in a state of squeezing the material storage airbag, and when the placement frame and the placement plate move to the internal position of the urine analyzer, the material storage airbag expands, and at this time, the material storage airbag absorbs disinfectant from the material box into itself through the connecting pipe and the feeding pipe, and then when the placement frame is moved out again, it squeezes the material storage airbag, and at this time, the material storage airbag sprays the disinfectant through the output pipe and the nozzle, and at this time, the placement frame and the placement plate are disinfected, and then the operator can wipe them clean, so that the urine remaining on the surface of the placement frame and the placement plate is cleaned, thereby ensuring the accuracy of each test;

[0029] Furthermore, when the connecting pipe and the feeding pipe are working, the second one-way valve allows the disinfectant to move only from the material box to the material storage airbag, and when the output pipe and the nozzle are working, the first one-way valve allows the disinfectant to move only from the material storage airbag to the nozzle, thereby ensuring the normal operation of the entire device;

[0030] (3) The multi-item auxiliary detection device for urology, when the placement frame enters the urine analyzer, the placement frame will slide inside the inner plate by pulling the sliding rod through the traction rope. At this time, the reset spring is squeezed, and when the placement frame moves back, the sliding rod will move back under the action of the reset spring, repeating the above process. The sliding rod drives the toggle block to make reciprocating linear motion in the horizontal direction, and then the toggle block can mix the disinfectant inside the material box, so that the disinfectant can better exert its effect.

At this time, the reset spring 23 is squeezed, and when the placing frame 2 moves back, the slide bar 20 will move back under the action of the reset spring 23, and the above process is repeated. The slide bar 20 drives the toggle block 21 to make reciprocating linear motion in the horizontal direction, and then the toggle block 21 can mix the disinfectant inside the material box 17, so that the disinfectant can better exert its effect.
