Description

Technical Field

[0001] The present invention belongs to the technical field of near-infrared spectroscopy detection, and specifically relates to a near-infrared spectroscopy detection device for sperm concentration. Background Art

[0002] Sperm concentration, as one of the key indicators for evaluating male fertility, is of great significance in the field of reproductive medicine. Accurately and quickly detecting sperm concentration plays a crucial role in the diagnosis of male infertility, the evaluation of the success rate of assisted reproductive technology, and related medical research.

[0003] Near-infrared spectroscopy technology has been widely used in many fields due to its advantages such as fast speed, non-destructive, pollution-free, and simple sample preparation; in recent years, the application of near-infrared spectroscopy technology in the field of biomedicine has gradually attracted attention, and it also shows good application prospects in sperm concentration detection. By measuring the absorption characteristics of sperm samples to near-infrared light, spectral information related to sperm concentration can be obtained, and then rapid and accurate detection of sperm concentration can be achieved.

[0004] Although near-infrared spectroscopy technology has many advantages in sperm concentration detection, there are still some deficiencies in the detection of sperm concentration. For example, during the detection, it is necessary for the staff to manually place the sample plate storing semen into the spectrometer, but there may be a problem of contamination of the sample plate storing semen during the placement process, and the detection accuracy will be affected due to the contamination.

[0005] Therefore, the present invention provides a near-infrared spectroscopy detection device for sperm concentration. Summary of the Invention

[0006] In order to make up for the deficiencies of the prior art and solve at least one technical problem proposed in the background art.

[0007] The technical solution adopted by the present invention to solve its technical problems is as follows: A near-infrared spectroscopy detection device for sperm concentration of the present invention includes a workbench; a spectral detection platform is installed above the workbench, a detector is installed on the upper end surface of the spectral detection platform through a bracket, a sample feeding seat is installed above the workbench and on the side of the spectral detection platform, a sample storage plate is arranged above the sample feeding seat, the sample storage plate stores semen to be detected inside, a guiding track is arranged inside the sample feeding seat, and the sample storage plate can move along the guiding track to a position corresponding to the detector.

[0008] Preferably, two rotating shafts are rotatably connected inside the sample feeding seat. The two rotating shafts are designed to be separated from each other. Connecting gears are fixedly installed on the outer circumferential surfaces of the two rotating shafts. The end of one of the rotating shafts is connected to the output end of an external driving motor. Transmission chains are meshed with the outer circumferential surfaces of the two connecting gears. A temporary storage plate is arranged on the outer circumferential surface of the transmission chain. The sample storage plate is placed on the surface of the temporary storage plate.

[0009] Preferably, a plurality of placing round rods I are arranged on the side wall of the temporary storage plate. The plurality of placing round rods I are designed to be separated from each other. A guiding frame is installed above the spectral detection platform. A detection seat is installed at the edge of the guiding frame and on the side of the transmission chain. A plurality of placing round rods II are installed on the surface of the detection seat. The plurality of placing round rods II are designed to be separated from each other. Friction groove patterns are formed on the surfaces of the placing round rods I and the placing round rods II. Rubber is arranged inside the friction groove patterns. The placing round rods II and the placing round rods I are arranged at intervals. The bottom of the sample storage plate is arc-shaped rubber.

[0010] Preferably, a limiting arc seat is installed on one side of the temporary storage plate away from the placing round rods I. The side of the limiting arc seat away from the temporary storage plate contacts the side wall of the guiding track. The upper ring surface and the lower ring surface of the guiding track are both designed to be arc-shaped; during operation, due to the design of the guiding track and the limiting arc seat, they will limit each other, which can not only improve the stability of the sample storage plate during movement, but also facilitate the placing round rods I to cross over the placing round rods II, so that the sample storage plate accurately stops above the placing round rods II.

[0011] Preferably, a contact point I is installed on the side wall of the limiting arc seat through a bracket. A contact point II is installed on the inner wall of the sample feeding seat and close to the detection seat. When the temporary storage plate drives the contact point I to move, it will contact the contact point II on the inner wall of the sample feeding seat; during operation, when the temporary storage plate moves along with the transmission chain and the placing round rods I cross over the placing round rods II, at this time, the limiting arc seat and the contact point I moving along with the temporary storage plate will contact the contact point II. Under the contact of the two, the external control circuit will be switched on, and the external controller will first control the rotating shaft to stop rotating and control the spectrometer and the detector to start working. In this way, when the sample storage plate accurately stops above the placing round rods II, the detection work can be immediately carried out, improving the detection efficiency.

[0012] Preferably, a plurality of transmission rollers are rotatably arranged inside the guiding frame. The transmission rollers are arranged on the side of the placing round rods II. Adjacent transmission rollers are connected by a belt. One of the transmission rollers is connected to the output end of an external driving motor. A recycling box is arranged above the workbench and at the edge of the guiding frame.

[0013] Preferably, a contact three is installed on the side wall of the sample storage plate, and a contact four is installed above the recovery frame. When the sample storage plate moves above the driving roller, the contact three will contact the contact four. An adsorption unit is arranged inside the sample storage plate, and the adsorption unit is used for adsorbing and recovering the semen after the detection is completed. During operation, when the sample storage plate moves along with the driving roller, the sample storage plate will drive the contact three to move at the same time. Subsequently, the contact three will contact the contact four above the recovery frame. At this time, the external circuit is connected, and it will control the adsorption unit to first adsorb the semen inside the sample storage plate, so as to facilitate the subsequent centralized treatment of the sample storage plate.

[0014] Preferably, the adsorption unit includes a hole groove opened inside the sample storage plate. An L-shaped transmission pipe is fixedly installed on the groove wall of the hole groove. A waste cavity is installed above the recovery frame, and a docking pipe is installed on the side wall of the waste cavity. The L-shaped transmission pipe and the docking pipe are designed on the same horizontal plane. During operation, when the contact three and the contact four are in contact, at this time, the L-shaped transmission pipe also just moves into the inside of the docking pipe. At this time, under the control of an external controller, the semen inside the sample storage plate will be adsorbed into the docking pipe through the hole groove and the L-shaped transmission pipe, and adsorbed into the waste cavity, so as to facilitate the separate treatment of the semen and the sample storage plate and avoid cross-contamination.

[0015] Preferably, a limiting plate is installed on the upper side inside the recovery frame. The limiting plate is connected to an external electric telescopic column, and the external electric telescopic column is arranged outside the recovery frame. During operation, when the semen inside the sample storage plate is adsorbed into the docking pipe through the hole groove and the L-shaped transmission pipe and adsorbed into the waste cavity, at this time, the limiting plate is located below the sample storage plate. After the adsorption is completed, the electric telescopic column is controlled to drive the limiting plate to move, so that the limiting plate moves away from the sample storage plate. After that, the sample storage plate after the adsorption is completed will fall into the recovery frame, so that the sample storage plate can be automatically recovered.

[0016] Preferably, a disinfection and cleaning solution is arranged inside the recovery frame. During operation, after the sample storage plate after the adsorption is completed falls into the recovery frame, the sample storage plate can be disinfected by the action of the disinfection and cleaning solution, which is convenient for its subsequent reuse.

[0017] The beneficial effects of the present invention are as follows: 1. For the near-infrared spectroscopy detection device for sperm concentration of the present invention, an external control motor drives one of the rotating shafts to rotate. The rotating shaft drives the connecting gear connected thereto to rotate. The connecting gear drives the transmission chain engaged therewith to rotate, so that the transmission chain drives the temporary storage plate and the sample storage plate to move and gradually move to a position corresponding to the detector, so as to facilitate the subsequent detection of semen and improve the conveying efficiency.

[0018] 2. When the temporary storage plate moves along with the transmission chain in the sperm concentration near-infrared spectrum detection device of the present invention, and when the placing round rod 1 passes over the placing round rod 2, at this time, the limiting arc seat and the contact point 1 moving along with the temporary storage plate will contact the contact point 2. Under the contact of the two, the external control circuit will be turned on, and the external controller will first control the rotation shaft to stop rotating and control the spectrometer and the detector to start working. In this way, when the sample storage plate can accurately stay above the placing round rod 2, the detection work can be immediately carried out, improving the detection efficiency.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] In order to make the technical means, creative features, achieved purposes and effects of the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0023] Such as Figures 1 to 7As shown in the figure, a near-infrared spectroscopy detection device for sperm concentration according to an embodiment of the present invention includes a workbench 1; above the workbench 1, a spectroscopy detection platform 2 is installed. At the upper end surface of the spectroscopy detection platform 2, a detector 201 is installed through a bracket. Above the workbench 1 and on the side of the spectroscopy detection platform 2, a sample feeding seat 3 is installed. Above the sample feeding seat 3, a sample storage plate 4 is provided. Inside the sample storage plate 4, semen to be detected is stored. Inside the sample feeding seat 3, a guiding track 301 is provided, and the sample storage plate 4 can move along the guiding track 301 to a position corresponding to the detector 201. During operation, the semen to be detected is placed inside the sample storage plate 4, and then the sample storage plate 4 is moved to a position corresponding to the detector 201 through the sample feeding seat 3 and the guiding track 301. Since a spectrometer and a detector 201 are provided above the spectroscopy detection platform 2, the detector 201 is used to receive the optical signal passing through the semen inside the sample storage plate 4 and convert it into an electrical signal. Subsequently, the collected spectral data is analyzed and processed through an external control system to calculate the sperm concentration. Under the action of the sample feeding seat 3, the sample storage plate 4 can be automatically transported, eliminating the need for manual handling by staff. Moreover, it also avoids the problem of contamination of the semen inside the sample storage plate 4 caused by manual transportation by staff, as well as the problem of affecting the detection accuracy due to contamination.

[0024] It should be noted that the detection method of the near-infrared spectrometer for the semen in the sample storage plate 4 is a prior art and will not be elaborated in the embodiments of the present invention.

[0025] Inside the sample feeding seat 3, two rotating shafts 5 are rotatably connected. The two rotating shafts 5 are designed to be separated from each other. On the outer peripheral surfaces of the two rotating shafts 5, connecting gears 6 are fixedly installed. The end of one of the rotating shafts 5 is connected to the output end of an external driving motor. On the outer peripheral surfaces of the two connecting gears 6, transmission chains 7 are engaged. On the outer peripheral surface of the transmission chain 7, a temporary storage plate 701 is provided. The sample storage plate 4 is placed on the surface of the temporary storage plate 701. During operation, referring to the attached Figure 2 and Figure 3 As shown in the figure, the starting position of the sample storage plate 4 is below the left side of the transmission chain 7 in the figure, that is, the staff can directly place the sample storage plate 4 on Figure 2 the surface of the temporary storage plate 701 below the left side of the transmission chain 7 in the figure. Then, an external control motor is used to drive one of the rotating shafts 5 to rotate. The rotating shaft 5 drives the connecting gear 6 connected to it to rotate. The connecting gear 6 drives the transmission chain 7 engaged with it to rotate, so that the transmission chain 7 drives the temporary storage plate 701 and the sample storage plate 4 to move and gradually move to a position corresponding to the detector 201, that is, Figure 2Above the right side of the transmission chain 7, which is convenient for subsequent detection of semen and improves the conveying efficiency.

[0026] A plurality of placing round rods I 801 are arranged on the side wall of the temporary storage plate 701. The plurality of placing round rods I 801 are designed to be separated from each other. A guiding frame 9 is installed above the spectral detection platform 2. A detection seat 10 is installed at the edge of the guiding frame 9 and on the side of the transmission chain 7. A plurality of placing round rods II 11 are installed on the surface of the detection seat 10. The plurality of placing round rods II 11 are designed to be separated from each other. Friction grooves are formed on the surfaces of the placing round rods I 801 and the placing round rods II 11, and rubber is arranged inside the friction grooves. The placing round rods II 11 and the placing round rods I 801 are arranged at intervals. The bottom of the sample storage plate 4 is arc-shaped rubber. During operation, in the above starting state, the sample storage plate 4 is placed on the placing round rods I 801. When the sample storage plate 4 and the temporary storage plate 701 move along with the transmission chain 7, the sample storage plate 4 will gradually move towards the side of the placing round rods II 11. Since the placing round rods II 11 and the placing round rods I 801 are arranged at intervals, when the sample storage plate 4 moves to the position of the placing round rods II 11, that is, when it moves to the position shown in Figure 4 the figure, the placing round rods I 801 will cross over the placing round rods II 11, and the sample storage plate 4 will remain on the upper end surface of the placing round rods II 11. In this way, the automatic placement of the sample storage plate 4 can be realized, which is convenient for subsequent detection by the spectrometer and the detector 201. It should be noted that since friction grooves are formed on the surfaces of the placing round rods I 801 and the placing round rods II 11, and rubber is arranged inside the friction grooves, and the bottom of the sample storage plate 4 is arc-shaped rubber, the friction force between the two is increased when they are in contact with the placing round rods I 801 and the placing round rods II 11, ensuring the stability of the sample storage plate 4 during conveying.

[0027] A limiting arc seat 702 is installed on the side of the temporary storage plate 701 away from the placing round rods I 801. The side of the limiting arc seat 702 away from the temporary storage plate 701 is in contact with the side wall of the guiding track 301. The upper and lower ring surfaces of the guiding track 301 are both designed as arcs. During operation, due to the design of the guiding track 301 and the limiting arc seat 702, they will limit each other, which can not only improve the stability of the sample storage plate 4 during movement, but also facilitate the placing round rods I 801 to cross over the placing round rods II 11, so that the sample storage plate 4 accurately stays above the placing round rods II 11.

[0028] A contact point I 12 is installed on the side wall of the limiting arc seat 702 through a bracket. A contact point II 13 is installed on the inner wall of the sample delivery seat 3 and near the detection seat 10. When the temporary storage plate 701 drives the contact point I 12 to move, it will contact the contact point II 13 on the inner wall of the sample delivery seat 3. During operation, when the temporary storage plate 701 moves along with the transmission chain 7 and the placement round rod one 801 passes over the placement round rod two 11, at this time, the limiting arc seat 702 and the contact one 12 moving along with the temporary storage plate 701 will contact the contact two 13. Under the contact of the two, the external control circuit will be turned on, and the external controller will first control the rotating shaft 5 to stop rotating and control the spectrometer and the detector 201 to start working. In this way, when the sample storage plate 4 can accurately stay above the placement round rod two 11, the detection work can be immediately carried out, improving the detection efficiency.

[0029] A plurality of transmission rollers 901 are rotatably arranged inside the guiding frame 9. The transmission rollers 901 are arranged on the side of the placement round rod two 11. Adjacent transmission rollers 901 are connected by a belt. One of the transmission rollers 901 is connected to the output end of an external driving motor. Above the workbench 1 and at the edge of the guiding frame 9, a recycling box 14 is arranged; Refer to the appendix Figure 3 and Figure 4 As shown, when the sample storage plate 4 falls above the placement round rod two 11, at this time, the lower part of the sample storage plate 4 contacts a part of the transmission rollers 901; when the spectrometer and the detector 201 start working and when the detection is completed, at this time, the external controller receives the detection completion signal. Therefore, the external controller will continue to control the rotating shaft 5 to rotate. The rotating shaft 5 drives the connecting gear 6 and the transmission chain 7 to rotate, so that it can drive the subsequent sample storage plates 4 to continue the detection; at the same time, the external controller will simultaneously control one of the transmission rollers 901 to rotate. Since adjacent transmission rollers 901 are connected by a belt, the transmission rollers 901 will drive the detected sample storage plate 4 to move, so that the sample storage plate 4 moves towards the side close to the recycling box 14. In this way, not only can the sample storage plates 4 to be detected be continuously transmitted, but also the detected sample storage plates 4 can be automatically recycled, improving the detection efficiency of sperm concentration.

[0030] A contact three 15 is installed on the side wall of the sample storage plate 4, and a contact four 16 is installed above the recycling box 14. When the sample storage plate 4 moves above the transmission roller 901, the contact three 15 will contact the contact four 16. An adsorption unit is arranged inside the sample storage plate 4, and the adsorption unit is used to adsorb and recycle the detected semen; During operation, when the sample storage plate 4 moves along with the transmission roller 901, the sample storage plate 4 will drive the contact three 15 to move at the same time. Subsequently, the contact three 15 will contact the contact four 16 above the recycling box 14. At this time, the external circuit is turned on, and it will control the adsorption unit to first adsorb the semen inside the sample storage plate 4, so as to facilitate the subsequent centralized processing of the sample storage plate 4.

[0031] The adsorption unit includes a hole groove 17 formed inside the sample storage plate 4. An L-shaped transmission pipe 18 is fixedly installed on the groove wall of the hole groove 17. A waste material cavity 19 is installed above the recovery frame 14. A docking pipe 20 is installed on the side wall of the waste material cavity 19. The L-shaped transmission pipe 18 and the docking pipe 20 are designed on the same horizontal plane. During operation, when the third contact 15 and the fourth contact 16 are in contact, at this time, the L-shaped transmission pipe 18 also just moves into the inside of the docking pipe 20. At this time, under the control of an external controller, the semen inside the sample storage plate 4 will be adsorbed into the docking pipe 20 through the hole groove 17 and the L-shaped transmission pipe 18, and adsorbed into the waste material cavity 19. In this way, it is convenient to separately process the semen and the sample storage plate 4, avoiding cross-contamination.

[0032] A limiting plate 21 is installed on the upper side inside the recovery frame 14. The limiting plate 21 is connected to an external electric telescopic column, and the external electric telescopic column is arranged outside the recovery frame 14. During operation, when the semen inside the sample storage plate 4 is adsorbed into the docking pipe 20 through the hole groove 17 and the L-shaped transmission pipe 18 and adsorbed into the waste material cavity 19, at this time, the limiting plate 21 is located below the sample storage plate 4. After the adsorption is completed, the limiting plate 21 is driven to move by controlling the electric telescopic column, so that the limiting plate 21 moves away from the sample storage plate 4. Then, the adsorbed sample storage plate 4 will fall into the recovery frame 14. In this way, the sample storage plate 4 can be automatically recovered. It should be noted that when the L-shaped transmission pipe 18 moves into the inside of the docking pipe 20, the contact position between the L-shaped transmission pipe 18 and the docking pipe 20 is made of soft rubber, so as to facilitate the recovery of the sample storage plate 4.

[0033] A disinfection and cleaning liquid is arranged inside the recovery frame 14. During operation, after the adsorbed sample storage plate 4 falls into the recovery frame 14, the sample storage plate 4 can be disinfected by the action of the disinfection and cleaning liquid, which is convenient for its subsequent reuse.

[0034] During operation, the detector 201 is used to receive the optical signal passing through the semen inside the sample storage plate 4 and convert it into an electrical signal. Subsequently, the collected spectral data is analyzed and processed through an external control system to calculate the sperm concentration. Under the action of the sample feeding seat 3, the sample storage plate 4 can be automatically transported, eliminating the need for manual handling by staff. Moreover, it also avoids the problem of contamination of the semen inside the sample storage plate 4 caused by manual transportation by staff, and also avoids the problem of affecting the detection accuracy due to contamination. Refer to the attached Figure 2 and Figure 3 As shown, the starting position of the sample storage plate 4 is located below the left side of the transmission chain 7 in the figure, that is, the staff directly places the sample storage plate 4 on Figure 2on the surface of the temporary storage plate 701 below the left side of the transmission chain 7. Then, an externally connected control motor drives one of the rotating shafts 5 to rotate. The rotating shaft 5 drives the connecting gear 6 connected thereto to rotate. The connecting gear 6 drives the transmission chain 7 engaged therewith to rotate, so that the transmission chain 7 drives the temporary storage plate 701 and the sample storage plate 4 to move and gradually move to a position corresponding to the detector 201, that is Figure 2 above the right side of the transmission chain 7 in the figure, which is convenient for subsequent detection of semen and improves the conveying efficiency; in the above initial state, the sample storage plate 4 is placed on the placing round rod 801. When the sample storage plate 4 and the temporary storage plate 701 move along with the transmission chain 7, the sample storage plate 4 will gradually move to one side of the placing round rod 11. Since the placing round rod 11 and the placing round rod 801 are spaced apart, when the sample storage plate 4 moves to the position of the placing round rod 11, that is, when it moves to the position Figure 4 shown in the figure, the placing round rod 801 will cross over the placing round rod 11, and the sample storage plate 4 will remain on the upper end surface of the placing round rod 11. In this way, the automatic placement of the sample storage plate 4 can be realized, which is convenient for subsequent detection by the spectrometer and the detector 201; When the temporary storage plate 701 moves along with the transmission chain 7 and the placing round rod 801 crosses over the placing round rod 11, at this time, the limiting arc seat 702 and the contact point 12 moving along with the temporary storage plate 701 will contact the contact point 13. Under the contact of the two, the externally connected control circuit will be turned on, and the external controller will first control the rotating shaft 5 to stop rotating and control the spectrometer and the detector 201 to start working. In this way, when the sample storage plate 4 accurately stays above the placing round rod 11, the detection work can be immediately carried out, which improves the detection efficiency; When the sample storage plate 4 falls above the placing round rod 11, at this time, the lower part of the sample storage plate 4 contacts a part of the driving roller 901; when the spectrometer and the detector 201 start working and after the detection is completed, at this time, the external controller receives the detection completion signal, so the external controller will continue to control the rotating shaft 5 to rotate. The rotating shaft 5 drives the connecting gear 6 and the transmission chain 7 to rotate, so that it can drive the subsequent sample storage plate 4 to continue the detection; at the same time, the external controller will simultaneously control one of the driving rollers 901 to rotate. Since the adjacent driving rollers 901 are connected by a belt, the driving roller 901 will drive the detected sample storage plate 4 to move, so that the sample storage plate 4 moves towards the side close to the recovery box 14. In this way, not only can the sample storage plate 4 to be detected be continuously conveyed, but also the detected sample storage plate 4 can be automatically recovered, which improves the detection efficiency of sperm concentration; When the sample storage plate 4 moves along with the driving roller 901, the sample storage plate 4 will drive the contact point three 15 at the same time. Subsequently, the contact point three 15 will contact the contact point four 16 above the recovery frame 14. At this time, the external circuit is turned on, and the adsorption unit will be controlled to adsorb the semen inside the sample storage plate 4 first, which is convenient for subsequent centralized processing of the sample storage plate 4. When the contact point three 15 and the contact point four 16 are in contact, at this time, the L-shaped transmission pipe 18 also just moves into the inside of the docking pipe 20. Under the control of the external controller, the semen inside the sample storage plate 4 will be adsorbed into the docking pipe 20 through the hole groove 17 and the L-shaped transmission pipe 18 and adsorbed into the waste cavity 19, which is convenient for separate treatment of the semen and the sample storage plate 4 and avoids cross-contamination.
