[0002] A breath sample collection card is a device used to collect breath samples. It is commonly used in medical research, clinical diagnosis, or testing. Patients collect breath samples into the collection card using a specific method, and nurses then use the sample on the collection card to perform tests.

[0003] For example, Chinese patent application CN116519653A discloses a portable fluorescence tester, including a terminal instrument and a mobile user terminal running a fluorescence test APP. The terminal instrument includes a housing, with a slot in the lower layer inside the housing, and a cavity inside the slot for inserting a test card. The upper space inside the housing contains a controller, a battery, an LED light source, a CCD image acquisition device, a wireless transceiver, and a USB interface. The controller is connected to the LED light source, the CCD image acquisition device, and the wireless transceiver.

[0004] However, when using this portable fluorescence analyzer, the user needs to insert a single sample into the cavity for testing, and then remove the sample and insert another sample. It cannot automatically complete the testing of a large number of samples, resulting in low efficiency and high cost.

[0031] In some embodiments, please refer to the accompanying drawings. Figures 1-5 An automatic continuous detection device for card-type samples includes a base plate 1.

[0032] The base plate 1 is equipped with a feeding device 2 for pushing and feeding samples, and a recognition and detection device 3 for scanning and detecting samples is installed on one side of the base plate 1.

[0033] The feeding device 2 includes a storage component 21 for storing samples and a pushing component 22 for pushing samples. The storage component 21 and the pushing component 22 are mounted on the base plate 1, and the pushing component 22 is located to the left of the storage component 21.

[0034] The identification and detection device 3 includes a conveying component 31 for driving sample conveying and an identification and detection component 32 for scanning and detection. The conveying component 31 is installed on one side of the base plate 1, and the identification and detection component 32 is installed on the upper end of the conveying component 31.

[0035] When the card-type sample automatic continuous detection device is in normal use, multiple samples are stacked in the storage component 21. The pushing component 22 is activated to push the bottom sample onto the conveying component 31. The conveying component 31 is activated to drive the sample into the identification and detection component 32. The identification and detection component 32 is activated to scan and detect the sample respectively. The sample that has been detected is conveyed and unloaded by the conveying component 31. The above steps are repeated. The continuous loading and unloading of samples is achieved through the cooperation of the pushing component 22 and the conveying component 31. The identification and detection of multiple samples are completed automatically. The operation is simple and the work efficiency is high.

[0036] The storage component 21 includes a sample compartment 211, a side cover 212, and a handle 213. The sample compartment 211 is fixedly installed on the upper end of the base plate 1. The upper end of the sample compartment 211 has a through hole for easy observation of the remaining sample amount. The lower end of the sample compartment 211 has through grooves on the left and right sides. The through grooves at the lower end of the sample compartment 211 are used to cooperate with the pusher component 22 to drive the sample to slide through. One side of the side cover 212 is rotatably connected to the sample compartment 211, and the other side of the side cover 212 is fixedly connected to the sample compartment 211 by a magnetic snap. The handle 213 is fixedly installed on the side of the side cover 212 near the magnetic snap.

[0037] The lower end of the inner wall on the right side of the sample compartment 211 is inclined to facilitate the passage of the sample when it rotates downwards on the right side.

[0038] The pushing assembly 22 includes an electric cylinder 221, a connecting plate 222, and a pusher plate 223. The electric cylinder 221 is fixedly installed on the upper end of the base plate 1. The output end of the electric cylinder 221 is fixedly connected to the connecting plate 222. The lower end of the connecting plate 222 is slidably connected to the base plate 1. The right end of the connecting plate 222 is fixedly connected to the pusher plate 223. The lower end of the pusher plate 223 is slidably connected to the base plate 1. The right side of the pusher plate 223 is gradually tilted and lowered from top to bottom.

[0039] The feeding assembly 22 also includes a pressure sensor 224, which is fixedly installed on the upper end of the push plate 223 and is electrically connected to the electric cylinder 221.

[0040] The conveying assembly 31 is a chain roller conveyor. The outer shell of the conveying assembly 31 is fixedly installed on the right end of the base plate 1. The upper end of the roller of the conveying assembly 31 is flush with the upper end surface of the base plate 1. The conveying direction of the roller of the conveying assembly 31 is from the side close to the sample chamber 211 and gradually away from the sample chamber 211. The identification and detection assembly 32 is installed on the upper end of the outer shell of the conveying assembly 31.

[0041] The identification and detection component 32 includes a bracket 321, a barcode scanner 322, and a detector body 323. The bracket 321 is fixedly installed on the upper end of the housing of the conveying component 31. The lower end of the bracket 321 is provided with a through groove for sample passage. The barcode scanner 322 is fixedly installed on the bracket 321, with its output end passing through the bracket 321 and facing downward. The detector body 323 is fixedly installed on the housing of the conveying component 31, located to the right of the barcode scanner 322. The output end of the detector body 323 faces downward, and the lower end of the detector body 323 is provided with a through groove for sample passage. The barcode scanner 322 is electrically connected to the detector body 323. The barcode scanner 322 is existing technology, and the detector body 323 is the main body of an existing technology detector.

[0042] The identification and detection component 32 also includes two supplementary lights 324, which are fixedly mounted on the bracket 321, with the illumination ends of the supplementary lights 324 passing through the bracket 321 and facing downwards.

[0043] A PLC controller (not shown in the figure) is also fixedly connected to the base plate 1; the PLC controller is electrically connected to the pressure sensor 224 and the electric cylinder 221;

[0044] When the automatic continuous detection device for card-type samples is in normal use, pulling the handle 213 forward causes the side cover 212 to rotate along the sample chamber 211, stacking multiple samples inside the sample chamber 211. Closing the side cover 212 then activates the electric cylinder 221, which moves the connecting plate 222 to the right. The connecting plate 222 then moves the push plate 223, which pushes the bottom sample to be tested in the sample chamber 211 to the right. The push plate 223 then moves the sample to be tested to the upper left side of the conveying assembly 31. The scanner 322 is then activated to scan the QR code on the sample and triggers the detection instrument body 323 to create a sample. In this information, the conveying assembly 31 is started. The roller of the conveying assembly 31 moves the sample to be tested to the right and stops below the main body of the detector 323. The sample that has been tested is simultaneously fed out by the conveying assembly 31. The main body of the detector 323 is started to test the sample. At this time, the push plate 223 and the pressure sensor 224 are located inside the sample chamber 211. The remaining sample to be tested in the sample chamber 211 falls onto the push plate 223 and squeezes the pressure sensor 224. After the pressure sensor 224 detects the pressure of the sample to be tested above, it controls the electric cylinder 221 to retract through the PLC controller and perform the next extension action of the electric cylinder 221. After the electric cylinder 221 drives the pusher plate 223 to move to the left, the lowest sample inside the sample chamber 211 gradually rotates along the inclined part of the right end of the pusher plate 223 until it contacts the bottom plate 1. When the pusher plate 223 completely exits the sample chamber 211, the lowest sample falls onto the bottom plate 1. The supplementary light 324 illuminates the sample surface when the barcode scanner 322 is activated, and the PLC controller continues to control the electric cylinder 221 to extend the pusher plate 223. The above steps are repeated until the pusher plate 223 is located inside the sample chamber 211 and the pressure sensor 224 does not detect pressure, indicating that there is no sample to be tested in the sample chamber 211. The pressure sensor 224 outputs a signal. The signal is transmitted to the PLC controller, which controls the electric cylinder 221 to return to its original position and stop operating. The conveying component 31 synchronously drives the loading and unloading of samples to be tested and samples that have been tested, realizing automatic sample loading and unloading and automatic continuous testing. There is no need for manual testing of each sample, which improves efficiency. The pressure sensor 224 is set so that the operation can be automatically identified and stopped after all samples in the sample chamber 211 have been tested, saving energy. The tilt setting on one side of the push plate 223 and the tilt setting on the inside of the sample chamber 211 ensures that one end of the sample contacts the bottom plate 1 first when it falls, avoiding direct drop and sample damage.

[0045] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
