Description
Technical Field
The application belongs to the technical field of medical detection equipment, and particularly relates to intelligent full-automatic unmanned multi-probe Raman spectrum analysis equipment.
Background
Raman spectroscopy is an analytical method based on Raman scattering effects found by indian scientist c.v. Raman (Raman) that analyzes a scattering spectrum at a frequency different from that of incident light to obtain information on molecular vibration and rotation, and is applied to molecular structure research. Because the analysis method of Raman spectrum does not need to pre-treat the sample and does not need the preparation process of the sample, and some errors are avoided, the method has the advantages of simple operation, short measurement time, high sensitivity and the like in the analysis process. Meanwhile, because the Raman spectrum of water is very weak and the spectrogram is very simple, the Raman spectrum is relatively suitable for researching the trace components of the liquid substance in a near natural state.
Urine is a product with complex components and is rich in human health information, and meanwhile, urine is a physiological sample which is most convenient and directly reflects the health condition of individuals, for example, the combined detection of trace urine albumin and beta 2-microglobulin in urine has index significance for early diagnosis of diabetic nephropathy. In general, urine detection in hospitals is generally performed by using a professional chemical analysis method, so that the detection items are more, the result is accurate, but the detection is time-consuming and inconvenient, the detection price is not enough, and only patients who really need detection can go to the hospitals for urine detection, which is therapeutic urine detection. If the ordinary person can perform urine detection in daily life, namely, daily health urine detection, the ordinary person can know the health condition of the ordinary person dynamically and in trend at any time, and the problem can be found without waiting until the disease is serious. That is, daily health urine testing is of great significance to the improvement of health index for individuals and society. To meet this demand, currently, urine test strips are commonly used for home urine test, and then the color change of the urine test strip is recognized by small electronic devices to determine the health condition of an individual. However, the existing method for detecting the urine in the household by using the test paper is neither sanitary nor convenient, and the detection result is also inaccurate. In addition, the test paper detection mode usually has only a few simple items, such as whether urine sugar is higher or not, whether uric acid is normal or not, and the like. Therefore, this simple detection method cannot detect more health information in urine, such as trace urine albumin and β2-microglobulin in urine, and the like, and its use is very limited.

Specifically, as shown in fig. 3, the signal switching device includes a switching connector 431, a line number buffer 432, a line number queue 433, a plurality of downlink information buffers 434 and a plurality of uplink information buffers 435, wherein the plurality of downlink information buffers 434 are electrically connected to the main control board, the plurality of uplink information buffers 435 are electrically connected to the plurality of sampling components in a one-to-one correspondence manner, the switching connector 431 is electrically connected to the main control board, the downlink information buffers 434, the uplink information buffers 435, the line number queue 433 and the line number buffer 432, and the line number queue 433 is electrically connected to the downlink information buffers 434, the uplink information buffers 435 and the line number buffer 432.
Taking the first to nth sampling components (n is a positive integer) as an example, the signal switching device 430 operates as follows:
In the first step, when the device is powered on for the first time, the central processing unit on the main control board 410 empties the first to nth download information buffers 434, the line number queue 433, the line number buffer 432, the first upload information buffer 435, the nth upload information buffer 435, and the like.
And in the second step, when the equipment starts to work, all the information uploaded by all the equipment in the first sampling assembly is stored in the first uploading information buffer 435, and meanwhile, the first line number is sent to the line number queue 433 to wait for reading, and similarly, all the information uploaded by all the equipment in the nth sampling assembly is stored in the nth uploading information buffer 435, and meanwhile, the nth line number is sent to the line number queue 433 to wait for reading.
Third, the cpu stores the information to be downloaded in the first download information buffer 434 and the nth download information buffer 434 according to the corresponding line numbers, and waits for reading after the signal line of the line number buffer 432 is passed to the line number (e.g. 1, 2, 3, etc.) corresponding to the line number queue 433. At this time, the line number queue 433 can insert only the line number which is not available according to the line number size, and the line number queue does not need to be inserted in the existing line number, regardless of whether the information is uploaded or downloaded.
Fourth, the signal switching device 430 reads the line number in the line number queue 433 to the line number buffer 432 and deletes the corresponding line number in the line number queue 433.
Fifth, the signal switching device 430 reads the line number in the line number buffer 432, reads the information in the first and n-th upload information buffers 435 and 435 on the line number according to the line number, and executes the information by the cpu, and reads and transmits all the information of the line number in the first and n-th download information buffers 434 and 434 according to the line number, and after the execution is completed, deletes the line number in the line number buffer 432, and similarly, executes the next line number. Until the current line number buffer is empty. Then, the signal switching apparatus 430 repeats the steps of the fourth step and the fifth step in a loop.
Referring also to fig. 4, in the present embodiment, the sampling tube 120 has an upper end opening 124 and a lower end opening 125 located below the upper end opening 124, and both the upper end opening 124 and the lower end opening 125 communicate with the inner cavity of the urinal 110. The switch assembly 130 includes a urine inlet magnetic valve switch 131 disposed at the upper opening 124, and a urine magnetic valve switch 132 disposed inside the sampling tube 120, wherein the urine inlet magnetic valve switch 131 and the urine magnetic valve switch 132 are electrically connected to the main control board 410 through a signal switching device 430. In this way, the main control board 410 can realize accurate control of the sampling device 100 to be sampled and detected, especially control of each magnetic valve switch in the sampling device 100, through the signal switching device 430, so as to realize unmanned automation of the sampling process. Specifically, the urine inlet magnetic valve switch 131 is mainly used for controlling the opening and closing of the upper end opening 124 of the sampling tube 120, and the urine magnetic valve switch 132 is mainly used for controlling the retention and release of urine in the sampling tube 120. In the practical use process, when the urine of the detected person enters the sampling tube 120 through the urine tube 110, the temperature detector 310, for example, the infrared temperature detector 311 will start to measure the temperature of the urine in the sampling tube 120, the central processing unit on the main control board 410 will receive the continuous temperature measurement information sent by the infrared temperature detector 311, when the central processing unit monitors that the temperature is higher than the ambient temperature value and continuously stabilizes to the preset value, the closing instruction will be sent to the urine inlet magnetic valve switch 131 and the urine magnetic valve switch 132, after the two switches are closed, the urine stays in the transparent sampling tube 120, thus, the detected urine in the sampling tube 120 is in the middle section meeting the medical sampling standard, the urine is in a stable state, the standard unification of the urine detection can be ensured, and the error is reduced to improve the accuracy of the urine detection.
As shown in fig. 4, in this embodiment, the sampling tube 120 includes a first tube segment 121, a second tube segment 122 and a third tube segment 123 sequentially connected, where the first tube segment 121 is disposed obliquely outward and downward compared with the axial direction of the urine tube 110, the second tube segment 122 is disposed horizontally, and the third tube segment 123 is disposed obliquely downward in the direction toward the urine tube 110, so that the receiving and temporary storage of urine are facilitated, and the sampling tube 120 is generally a transparent tube for facilitating the observation of the urine level and the detection of laser irradiation. Of course, in other embodiments, the lower opening 125 of the sampling tube 120 may be further connected to other pipes for urine discharge, but in this embodiment, the bent sampling tube 120 is integrally connected to the urine tube 110, and the upper opening 124 and the lower opening 125 are both connected to the inner cavity of the urine tube 110, so that the extra pipes can be avoided, and the structure of the sampling device 100 is simpler and the occupied space is smaller. In addition, in another embodiment shown in fig. 5, besides the aforementioned component structure, a slag separation net 140 is covered at the inlet of the urine tube 110, and the slag separation net 140 mainly plays a role in isolating impurities irrelevant to urine detection, so that the accuracy of the urine detection by the device can be further improved.
In this embodiment, as shown in fig. 4, the laser switch 380 is connected to the optical path of the laser probe 330 through an optical fiber 360, the detection end of the laser probe 330 extends into the second pipe section 122 from the upper side wall of the second pipe section 122, the other end of the laser probe 330 is connected to the raman scattering collector 340 through the optical fiber 360, and the raman scattering collector 340 is connected to the raman scattering processor 350 through the laser switch 380. The detection end of the temperature detector 310 extends into the second pipe section 122 from the upper side wall of the second pipe section 122, the detection end of the laser probe 330 and the detection end of the temperature detector 310 are both spaced from the urine liquid level in the second pipe section 122, meanwhile, the urine magnetic valve switch 132 is positioned in the second pipe section 122 adjacent to the third pipe section 123, and a space is reserved between the top end of the urine magnetic valve switch 132 and the top of the inner wall surface of the second pipe section 122. Here, the temperature detector 310 is preferably a non-contact infrared temperature detector 311 to avoid contact with urine as much as possible, however, in other embodiments, the temperature detector 310 may be an immersion contact temperature detector, which is not limited herein. Specifically, the raman scattering collector 340 and the laser probe 330 are both disposed and fixed perpendicular to the second tube section 122, and the infrared thermometer 311 is disposed above the second tube section 122, so as to continuously detect temperature, and the detection ends of the laser probe 330 and the infrared thermometer 311 are substantially flush with or slightly protrude from the inner wall of the second tube section 122, so as to realize the detection function, and at the same time, avoid urine pollution, and further avoid poor testing caused by sample pollution.
Specifically, the inner pipe diameter of the first pipe section 121 is smaller than the inner pipe diameter of the second pipe section 122. Preferably, the distance between the top end of the urine magnetic valve switch 132 and the top of the inner wall surface of the second tube section 122 is 1/4 to 1/2 of the inner tube diameter of the second tube section 122, and in the present embodiment, the distance may be further preferably 1/4, i.e., the height of the urine magnetic valve switch 132 is preferably 3/4 of the inner tube diameter of the second tube section 122. It will be appreciated that since the height of the urine magnetic valve switch 132 is 3/4 of the inner diameter of the second tube section 122, when the urine magnetic valve switch 132 is closed, only the 3/4 of the inner diameter of the second tube section 122 is closed, and the urine magnetic valve switch 132 is not fully closed, i.e. the urine is excessive, and the urine liquid level in the second tube section 122 does not exceed the 3/4 of the inner diameter thereof. Thus, the top of the inner wall surface of the second tube section 122 is not contacted with urine, so that the top area is not polluted by urine, and inaccurate detection information caused by pollution of the top of the second tube section 122 is reduced.
Further, referring to fig. 4, in the present embodiment, for the purpose of facilitating the sampling of the sampling tube 120, an inner protrusion 111 is protruded on the inner wall surface of the urine tube 110, and the inner protrusion 111 may be annular or may be formed by a plurality of protrusions circumferentially arranged along the inner wall surface of the urine tube 110 at intervals, and the inner protrusion 111 is preferably disposed at a lower middle portion of the urine tube 110. The tip end surface of the inner protrusion 111 is inclined downward in a direction toward the center of the cross section of the urine tube 110, and the upper end opening 124 is exposed on the tip end surface of the inner protrusion 111 after the inner protrusion 111 is inserted into one side of the sampling tube 120, so that urine flowing down from the urine tube 110 will be stopped on the tip end surface of the inner protrusion 111 temporarily and not completely flow out immediately, and urine will flow into the sampling tube 120 from the upper end opening 124 of the sampling tube 120 due to the inclined tip end surface of the inner protrusion 111.
Referring to fig. 1 and 2, in the present embodiment, the intelligent fully-automatic unmanned multi-probe raman spectrum analysis device further includes a flush switch for flushing the sampling tube 120, wherein the flush switch is disposed on the urine tube 110 and electrically connected with the main control board 410 through the signal switching device 430, so that the flush switch on the corresponding sampling device 100 can be precisely controlled to be opened and closed through the signal switching device 430, thereby achieving the purpose of automatically flushing the corresponding sampling tube 120. Here, the flushing switch may be preferably a magnetic valve switch and connected to the water pipe, so as to automatically clean the sampling tube 120, thereby ensuring that the current urine is not polluted by the previous urine and improving the detection accuracy. Specifically, when the sensing module 210 senses that the detected person is detected by, for example, a human infrared sensor, it sends an on signal to the flushing switch to flush the sampling tube 120 for the first time, and sends an off signal to close the flushing switch after a preset time, for example, 3 seconds, when the detected person is detected to leave, it sends an on signal to the flushing magnetic valve switch again through the main control board 410 to flush the sampling tube 120 for the second time, and sends an off signal after a preset time, and clean water for flushing in the two flushing processes enters from the upper end opening 124 of the sampling tube 120, and flows out from the lower end opening 125 after automatically cleaning the sampling tube 120.
Referring to fig. 1 and 2, in the present embodiment, the identification module 220 includes a face recognition device and a card reader, the sensing module 210 includes a human body infrared sensor, the face recognition device and the card reader are connected with the cloud server 700 sequentially through the signal switching device 430, the main control board 410 and the Communication module 420, the human body infrared sensor is connected with the main control board 410 through the signal switching device 430, however, in other embodiments, the identification module 220 may be another type of identity recognition device, the sensing module 210 is not limited to the human body infrared sensor, but in the present embodiment, the device is contaminated in an unclean environment for a long time, and preferably, the device for acquiring information in a contactless manner such as the human body infrared sensor, the face recognition device, the NFC (NEAR FIELD Communication) card reader is used, so that the detected person avoids the risk of contact pollution. Specifically, since the NFC card information or the face recognition information of the detected person is read before urine detection, when the detection report is generated, the association between the detection result and the identity of the detected person is automatically performed, so that the automatic matching between the detection report and the detected person can be realized. After the detection is completed, the device can automatically store the detection result in the cloud server 700 through the communication module 420, so that a detected person can check the detection report at any time and any place, and the device is very convenient. In addition, in this embodiment, the face recognition device may be used to identify whether the user is a registered user, if not, urine analysis is not performed, and if the user is a registered user, urine analysis processing is performed.
In addition, in this embodiment, the intelligent fully-automatic unmanned multi-probe raman spectrum analysis device further includes a positioning module 800 installed on the sampling device 100, and the positioning module 800 is connected with the cloud server 700 in information through the signal switching device 430, the main control board 410 and the communication module 420 in sequence. The communication module is preferably 5G network communication, but may be WIFI network communication or other network communication in other embodiments. It can be understood that after the positioning module 800 is set, the user can search the nearest equipment from the mobile phone end for urine detection through the GPS positioning information, the operator can also use the positioning module 800 to determine whether the equipment is moved, and certainly, if the equipment fails, the maintainer can also position the failed equipment for maintenance through the GPS positioning information.
Finally, by integrating the above technical solutions and referring to fig. 1 to 4, the whole operation flow of the intelligent fully-automatic unmanned multi-probe raman spectrum analysis device is as follows:
The first phase is the preparation phase of the device. Firstly, when the power supply 500 is turned on for the first time, the positioning module 800 sends positioning information of a sampling component selected by a detected person to the cloud server 700 through communication between the communication module 420 and the 5G network, then, a central processing unit on the main control board 410 selects corresponding signal channels to send information through the signal switching device 430 so as to turn on the urine inlet magnetic valve switch 131 and turn off the urine magnetic valve switch 132, meanwhile, the central processing unit also sends a continuous temperature measurement starting signal to the infrared temperature detector 311 through the signal switching device 430, the infrared temperature detector 311 transmits the measured temperature information to the central processing unit through the signal switching device 430 and sets and stores the temperature value as an environmental temperature value, then, the central processing unit sends a continuous temperature measurement stopping signal to the infrared temperature detector 311 through the signal switching device 430 to stop temperature measurement, meanwhile, sends a stopping signal to the flushing switch through the signal switching device 430 and simultaneously sends off information to the flushing switch, and at the moment, the equipment enters a normal working state.
The second stage is the formal working stage of the device. When the human body infrared sensor on the sampling assembly senses the detected person, the central processor on the main control board 410 sends an opening signal to the flushing switch through the signal switching device 430 to flush the sampling tube 120 for the first time, and sends a closing signal to close the flushing switch after a preset time, for example, 3 seconds. Meanwhile, the central processing unit sends an opening signal to the face recognition device through the signal switching device 430 to perform face recognition, or a detected person actively swipes the NFC card to read NFC card information, the information is sent to the central processing unit through the signal switching device 430, after the central processing unit receives the information, the central processing unit can compare the face recognition information or the NFC card information with registered users stored in the cloud server 700 through communication modules 420 and 5G network communication, if the user is a non-registered user, urine detection is not performed, if the user is a registered user, the information is fed back to the central processing unit, and then the central processing unit sends a continuous temperature measurement signal to the infrared temperature detector 311 through the signal switching device 430 to perform continuous temperature measurement. When the urine starts to be urinated, urine is collected at the bottom of the urinal and enters the urine tube 110, and then falls on the inclined top end surface of the inner convex part 111, at this time, the urine inlet magnetic valve switch 131 is in an open state, and urine can automatically enter the transparent sampling tube 120 under the action of gravity. In the process of urine entering the sampling tube 120, the infrared thermometer 311 continuously measures the temperature and sends the measured result to the cpu through the signal switching device 430, and after the cpu monitors that the temperature is stable higher than the ambient temperature, the cpu sends a related signal through the signal switching device 430 to simultaneously close the urine inlet magnetic valve switch 131 and the urine magnetic valve switch 132. Meanwhile, the central processing unit sends a closing signal to the infrared thermometer 311 through the signal switching device 430 to stop the temperature measurement and control the laser emission source 320 to emit laser, the laser irradiates the urine in the transparent sampling tube 120 after reaching the laser probe 330 through the optical fiber 360 and the laser switcher 380 to form raman scattered optical signals, the raman scattered optical signals are collected by the raman scattering collector 340 and transmitted to the raman scattering processor 350 through the optical fiber 360 and the laser switcher 380 (the raman scattering processor 350 can be integrated on the main control board 410 or can be arranged separately), then the raman scattering processor 350 converts the optical signals into digital information and transmits the digital information to the central processing unit, and then the central processing unit can quickly transmit the information to the cloud server 700 for storage and analysis processing through the communication module 420 and the 5G network communication.
After the detection is completed, the central processing unit sends a signal to open the urine inlet magnetic valve switch 131 and the urine magnetic valve switch 132 through the signal switching device 430, so that urine in the sampling tube 120 flows out from the lower end opening 125 of the sampling tube 120, i.e., the urine outlet, under the action of gravity. When the human body infrared sensor senses that the detected person leaves, an opening signal is sent to the flushing switch through the central processing unit of the main control board 410 so as to flush the sampling tube 120 for the second time, and a closing signal is sent after a preset time, for example, 3 seconds, clear water for the second flushing enters from the upper end opening 124 of the sampling tube 120, namely, the urine inlet, automatically washes the sampling tube 120, and then flows out from the lower end opening 125 of the sampling tube 120, namely, the urine outlet. Thus, urine analysis of the intelligent full-automatic unmanned multi-probe Raman spectrum analysis equipment is completed, and real-time urine detection can be realized. Of course, this process is only the operation of one sampling assembly, and the operation of a plurality of sampling assemblies can be performed sequentially or simultaneously under the action of the signal switching device 430 and the laser switch 380 of the present apparatus, and the operation of each sampling assembly is identical to the foregoing.
The foregoing description of the preferred embodiments of the application is not intended to be limiting, but rather is intended to cover all modifications, equivalents, and alternatives falling within the spirit and principles of the application.
