Description

Technical Field

[0001] The invention relates to the technical field of automatic bacterial inoculation, in particular to an automatic bacterial inoculation instrument. Background Art

[0002] There are many methods for bacterial inoculation, such as streak method, coating method, pouring method, slant inoculation method, liquid medium inoculation method, spiral inoculation method, etc., with different methods and applications. The spiral inoculation method allows rapid bacterial inoculation without any total or intermediate dilution. The logarithmically reduced sample volume is automatically dispensed on the rotating culture medium surface in the form of an Archimedean spiral. The volume at each point on the culture medium can be known and calibrated. The concentration of the bacterial solution can be calculated by dividing the number of colonies in a certain area on the culture dish by the amount of sample dispensed in the same area.

[0003] Direct testing of respiratory secretions (sputum) is an important diagnostic method for many respiratory diseases. When the existing bacterial inoculator is used in the respiratory department to diagnose the patient's condition, medical staff generally hold an inoculation loop to inoculate the respiratory secretions. During the long-term inoculation process, the medical staff's hands always maintain a posture, and the muscles are in a highly tense state, which can easily cause harm to the medical staff's body and affect the subsequent inoculation effect, thereby affecting the diagnosis of the patient's respiratory disease.

[0004] Therefore, an automatic bacterial inoculator is proposed. Summary of the invention

[0005] The purpose of the present invention is to provide an automatic bacterial inoculator. By setting up an inoculation mechanism, with the cooperation of a rotating mechanism, medical staff do not need to hold an inoculation loop to inoculate the respiratory secretions inside the inoculation dish, so that during long-term inoculation, the workload of medical staff can be reduced, and the arm muscles of medical staff can be avoided from being in a highly tense state, which is beneficial to ensuring the health of medical staff. At the same time, the respiratory secretions can be continuously inoculated, so that the inoculation loop can automatically leave the inside of the inoculation dish after the inoculation is completed, which is convenient for removing the inoculated inoculation dish from the upper end of the support platform, thereby improving the efficiency of inoculation, so as to solve the problems raised in the above-mentioned background technology.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: an automatic bacterial inoculator, comprising a support frame, a motor is fixedly installed on the right side of the lower end of the support frame, a No. 1 rotating shaft is rotatably installed on the upper end of the motor, the No. 1 rotating shaft penetrates the support frame and extends to the upper end of the support frame, a support platform is movably installed on the upper end of the support platform, an inoculation dish is movably installed on the upper end of the support platform, and an inoculation mechanism is movably provided on the upper end of the support frame.

[0007] First, place the respiratory secretions to be inoculated at the center of the upper end of the inoculation dish, fix the inoculation dish on the upper end of the support platform, connect the motor to the external power supply, and with the cooperation of the No. 1 rotating shaft, drive the support platform and the inoculation dish to rotate at the upper end of the support frame. With the cooperation of the inoculation mechanism, the respiratory secretions inside the inoculation dish are connected. By setting up the inoculation mechanism, the respiratory secretions can be rotated for inoculation, and medical staff are required to manually inoculate. This reduces the workload of medical staff and also alleviates the work burden of medical staff.

[0008] Preferably, the inoculation mechanism includes an inoculation ring, a gear, a rack, a rubber block, a rubber block, a support plate and a second rotating shaft, the gear fixed sleeve is arranged on the outer surface of the first rotating shaft, the rack is slidably installed on the upper rear end of the support frame, and the rack is meshed with the gear, the rubber block is fixedly installed on the left side of the rack, and the rubber block is movably installed on the left rear end of the upper end of the support frame, the support plate is fixedly installed on the left side of the upper end of the rack, the fixed plate is evenly fixedly installed on the upper rear end of the support plate, the second rotating shaft is rotatably installed at the upper end position between the two groups of fixed plates, and the second rotating shaft passes through the front fixed plate, the inoculation ring fixed sleeve is arranged in the middle of the outer surface of the second rotating shaft, and the inoculation ring is in contact with the inoculation dish;

[0009] The movable sleeve at the front end of the outer surface of the No. 2 rotating shaft is provided with a rotating mechanism, and the rotating mechanism includes a fixed block, a U-shaped plate, a No. 1 spring, a connecting rope and a return spring. The fixed block is slidably sleeved at the lower end of the outer surface of the supporting platform, and the U-shaped plate slides through the front end of the supporting plate, and the U-shaped plate cooperates with the fixed block. The No. 1 spring is movably sleeved at the upper left end of the outer surface of the U-shaped plate, and the No. 1 spring is fixedly connected to the upper end of the supporting plate. The connecting rope is fixedly sleeved at the front end of the outer surface of the No. 2 rotating shaft, and the connecting rope is fixedly connected to the left side of the upper end of the U-shaped plate. The return spring is movably sleeved at the outer surface of the No. 2 rotating shaft, and the return spring is located between the connecting rope and the front fixed plate.

[0010] The rear end rotating sleeve of the second rotating shaft is provided with a damping bearing, and the damping bearing is located between the inoculation ring and the rear end fixed plate.

[0011] The inoculation dish is pressed by hand to move downward, and the inoculation dish drives the support platform to move downward. The fixed block is slidably connected to the support platform. The fixed block will first move downward with the support platform. When the fixed block moves to contact with the No. 1 rotating shaft, under the support of the No. 1 rotating shaft, the fixed block will move upward relatively on the outer surface of the support platform. Since the U-shaped plate cooperates with the fixed block, when the fixed block moves downward with the support platform, it will squeeze the U-shaped plate to move downward, thereby pulling the connecting rope. At this time, the connecting rope drives the No. 2 rotating shaft to rotate, so that the inoculation ring can rotate to the inoculation dish. The motor is connected to the external power supply, and the motor drives the No. 1 rotating shaft to rotate while driving the gear to rotate. The gear is meshed with the rack, so when the gear rotates, it will drive the rack to move to the left at the upper end of the support frame. The inoculation ring and the No. 2 rotating shaft are connected to the gear through the fixed plate and the support plate, so the inoculation ring will move to the left with the rack, thereby spirally inoculating the respiratory secretions inside the inoculation dish. When the inoculation ring moves to the leftmost side of the inoculation dish, the U-shaped plate is not in contact with the fixed block, and at this time, the U-shaped plate is driven to move upward under the elastic force of the No. 1 spring. The second rotating shaft and the inoculation ring are driven to rotate under the elastic force of the return spring, so that the inoculation ring is in a vertical state and the inoculation ring does not contact the inoculation dish. The outer surface movable sleeve of the second rotating shaft is provided with a damping bearing, so that the inoculation ring can rotate slowly when rotating, reducing the phenomenon of bringing out the respiratory secretions inside the inoculation dish. After the inoculation is completed, the motor stops running, and the elastic force of the rubber block pushes the rack to move to the right at the upper end of the support frame. The teeth on the rack are connected by a one-way bearing, so the rack will not drive the first rotating shaft to move when it moves to the right. The inoculation mechanism is arranged to rotate, and with the cooperation of the rotating mechanism, the medical staff does not need to hold the inoculation ring to inoculate the respiratory secretions inside the inoculation dish. This can reduce the workload of the medical staff during long-term vaccination, avoid the arm muscles of the medical staff being in a highly tense state, and help ensure the health of the medical staff. At the same time, the respiratory secretions can be continuously inoculated, so that the inoculation ring can automatically leave the inside of the inoculation dish after the vaccination is completed, making it easy to remove the inoculated inoculation dish from the upper end of the support platform, thereby improving the efficiency of vaccination.

[0012] Preferably, a clamping mechanism is movably provided on the outer surface of the inoculation dish, and the clamping mechanism includes a slider, a third rotating shaft, a clamping block and a mounting groove, the slider is evenly fixedly installed on the outer surface of the fixed block, the third rotating shaft is evenly fixedly installed on the outer surface of the supporting platform, the clamping block is rotatably sleeved on the outer surface of the third rotating shaft, and the clamping block cooperates with the inoculation dish, and the mounting groove is provided at the lower end of the clamping block close to the supporting platform;

[0013] The sliding block is in the shape of a T-shaped body, the mounting groove is in an inclined shape, and the mounting groove is slidably connected to the clamping block;

[0014] A demoulding mechanism is movably provided at the upper inner end of the No. 1 rotating shaft, and the demoulding mechanism includes a slot, a No. 2 spring, a movable slot, a No. 3 spring, a positioning block, a positioning slot, a connecting rod and an electromagnet. The slot is arranged at the upper inner end of the No. 1 rotating shaft, and the No. 2 spring is movably inserted in the lower inner end of the slot. At this time, the No. 2 spring is in a compressed state due to the pressure of the supporting platform, and the No. 2 spring is fixedly connected to the lower end of the supporting platform. The movable slot is arranged at the front inner end of the No. 1 rotating shaft, and the No. 3 spring and the positioning block are movably installed in the interior of the movable slot from front to back, and the No. 3 spring is fixedly connected to the positioning block. The positioning slot is arranged at the lower inner end of the supporting platform, and the positioning slot cooperates with the positioning block. The connecting rod is fixedly installed on the right side of the U-shaped plate, and the electromagnet is fixedly installed on the right side of the rear end of the connecting rod. The positioning block is made of a magnet, and the positioning block is attracted to the electromagnet.

[0015] With the cooperation of the inoculation mechanism and the rotating mechanism, when the inoculation dish is placed on the upper end of the support platform by hand, the hand of the person will give the inoculation dish a downward pressure, so that the inoculation dish can drive the support platform to move toward the inside of the slot, and the support platform will squeeze the positioning block into the inside of the movable slot during the movement. When the positioning slot is connected to the movable slot, there is no pressure applied by the hand at this time. Under the elastic force of the No. 3 spring, the positioning block can be pushed out from the inside of the movable slot and pushed into the inside of the positioning slot. At this time, the support platform is fixed in the slot and cannot move. When the support platform moves downward, it will drive the fixed block to move downward. The slider is evenly fixed on the outer surface of the fixed block, so that the fixed block can drive the slider to slide inside the installation slot. The installation slot is inclined. When the slider slides downward, it can drive the clamping block to rotate with the No. 3 rotating shaft as the center, so that the upper end of the clamping block approaches the direction of the inoculation dish, and the clamping block can clamp the inoculation dish. When the U-shaped plate moves, the connecting rod drives the electromagnet to move with the U-shaped plate. When the U-shaped plate moves to the leftmost side, the electromagnet has magnetism, and the No. 1 rotating shaft starts to stop rotating. Since the electromagnet and the positioning block attract each other, the electromagnet can move the positioning block out of the inside of the positioning groove and into the inside of the movable groove. Under the elastic force of the No. 2 spring, the supporting platform is pushed to move upward to push the inoculation dish. At the same time, the fixed block drives the slider to slide upward in the installation groove, so that the upper end of the clamping block moves away from the inoculation dish. By setting a clamping mechanism and a demoulding mechanism, the inoculation dish can be automatically clamped, so that when the inoculation dish rotates with the supporting platform, the inoculation dish will not move on the upper end of the supporting platform under the action of inertia, thereby ensuring the effect of inoculation, and the inoculation dish after inoculation can be automatically pushed away from the upper end of the supporting platform, which is convenient for medical staff to take the inoculation dish after inoculation, thereby further improving the efficiency of inoculation.

[0016] Preferably, a disinfection mechanism is movably provided on the left upper end of the support frame, and the disinfection mechanism includes a switch, a disinfection box, a disinfection lamp, a through groove, a reflector and a mounting frame. The mounting frame is fixedly mounted on the left upper end of the support frame, and the mounting frame is located at the front and rear ends of the rubber block. The switch is movably mounted on the disinfection box, which is fixedly mounted on the lower rear end of the mounting frame, and the switch cooperates with the support plate at the upper end of the mounting frame. The disinfection lamp is symmetrically mounted on the front and rear ends of the disinfection box. The through groove is opened on the left side of the disinfection box, and the disinfection box cooperates with the inoculation ring, and the reflector is fixedly mounted on both sides of the disinfection box.

[0017] With the cooperation of the inoculation mechanism and the rotating mechanism, the inoculation ring will pass through the through slot and enter the interior of the disinfection box when it rotates. At the same time, the support plate contacts the switch on the mounting frame, thereby triggering the disinfection lamp to turn on. The disinfection lamp disinfects the inoculation ring. The reflectors installed on both sides of the disinfection box can increase the disinfection range of the disinfection lamp and enhance the disinfection effect of the disinfection lamp. By setting up a disinfection mechanism, the inoculation ring can be disinfected after the inoculation is completed, so that when the inoculation ring inoculates the next respiratory secretion, it will not affect the inoculation effect, thereby ensuring the accuracy of the patient's diagnosis. Moreover, the disinfection lamp will only be turned on when the inoculation ring needs to be disinfected, which is beneficial to extend the service life of the disinfection lamp and avoid waste of resources.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. By setting up the inoculation mechanism, with the cooperation of the rotating mechanism, the medical staff does not need to hold the inoculation loop to inoculate the respiratory secretions inside the inoculation dish, so that during long-term inoculation, the workload of the medical staff can be reduced, and the arm muscles of the medical staff can be prevented from being in a highly tense state, which is beneficial to ensure the health of the medical staff. At the same time, the respiratory secretions can be continuously inoculated, so that the inoculation loop can automatically leave the inside of the inoculation dish after the inoculation is completed, which is convenient for removing the inoculated inoculation dish from the upper end of the support platform, thereby improving the efficiency of inoculation;

[0020] 2. By setting up a clamping mechanism and a demoulding mechanism, the inoculation dish can be automatically clamped so that when the inoculation dish rotates with the support platform, the inoculation dish will not move on the upper end of the support platform due to inertia, thereby ensuring the inoculation effect. The inoculated inoculation dish can also be automatically pushed away from the upper end of the support platform after inoculation, making it convenient for medical staff to take the inoculation dish after inoculation, further improving the efficiency of inoculation.

By setting up the inoculation mechanism 2, the respiratory secretions can be rotated for inoculation, and medical staff are not required to manually inoculate, which reduces the workload of medical staff and also alleviates the work burden of medical staff.

[0030] As an embodiment of the present invention, Figures 1 to 3 As shown, the inoculation mechanism 2 includes an inoculation ring 201, a gear 202, a rack 203, a rubber block 204, a rubber block 204, a support plate 205 and a second rotating shaft 207. The gear 202 is fixedly sleeved on the outer surface of the first rotating shaft 102, the rack 203 is slidably installed on the upper rear end of the support frame 1, and the rack 203 is meshed with the gear 202, the rubber block 204 is fixedly installed on the left side of the rack 203, and the rubber block 204 is movably installed on the upper left rear end of the support frame 1, the support plate 205 is fixedly installed on the upper left side of the rack 203, the fixed plate 206 is evenly fixedly installed on the upper rear end of the support plate 205, the second rotating shaft 207 is rotatably installed at the upper end position between the two groups of fixed plates 206, and the second rotating shaft 207 passes through the front fixed plate 206, the inoculation ring 201 is fixedly sleeved on the middle part of the outer surface of the second rotating shaft 207, and the inoculation ring 201 is in contact with the inoculation dish 104;

[0031] The front end of the outer surface of the second rotating shaft 207 is movably sleeved with a rotating mechanism 3, and the rotating mechanism 3 includes a fixed block 301, a U-shaped plate 302, a first spring 303, a connecting rope 304 and a return spring 305. The fixed block 301 is slidably sleeved on the lower end of the outer surface of the supporting platform 103, the U-shaped plate 302 slides through the front end of the supporting plate 205, and the U-shaped plate 302 cooperates with the fixed block 301, the first spring 303 is movably sleeved on the upper left end of the outer surface of the U-shaped plate 302, and the first spring 303 is fixedly connected to the upper end of the supporting plate 205, the connecting rope 304 is fixedly sleeved on the front end of the outer surface of the second rotating shaft 207, and the connecting rope 304 is fixedly connected to the left upper end of the U-shaped plate 302, the return spring 305 is movably sleeved on the outer surface of the second rotating shaft 207, and the return spring 305 is located between the connecting rope 304 and the front fixed plate 206;

[0032] The rear end rotating sleeve of the second rotating shaft 207 is provided with a damping bearing 4, and the damping bearing 4 is located between the inoculation ring 201 and the rear end fixing plate 206;

[0033] During operation, the inoculation dish 104 is pressed by hand to move downward, and the inoculation dish 104 drives the support platform 103 to move downward. The fixed block 301 is slidably connected to the support platform 103. The fixed block 301 will first move downward with the support platform 103. When the fixed block 301 moves to contact the first rotating shaft 102, under the support of the first rotating shaft 102, the fixed block 301 will move upward relative to the outer surface of the support platform 103. Since the U-shaped plate 302 cooperates with the fixed block 301, when the fixed block 301 moves downward with the support platform 103, the U-shaped plate 302 will be squeezed to move downward, thereby pulling the connecting rope 304. At this time, the connecting rope 304 drives the second rotating shaft 102 to move downward. The No. 1 rotating shaft 207 rotates so that the inoculation ring 201 can rotate to contact the inside of the inoculation dish 104, and the motor 101 is connected to an external power source. The motor 101 drives the No. 1 rotating shaft 102 to rotate and drives the gear 202 to rotate at the same time. The gear 202 is meshed with the rack 203. Therefore, when the gear 202 rotates, it will drive the rack 203 to move to the left at the upper end of the support frame 1. The inoculation ring 201 and the No. 2 rotating shaft 207 are connected to the gear 202 through the fixed plate 206 and the support plate 205. Therefore, the inoculation ring 201 will move to the left with the rack 203, thereby spirally inoculating the respiratory secretions inside the inoculation dish 104. When the inoculation ring 201 When it moves to the leftmost side of the inoculation dish 104, the U-shaped plate 302 is not in contact with the fixed block 301. At this time, the U-shaped plate 302 is driven upward by the elastic force of the No. 1 spring 303. At the same time, the No. 2 rotating shaft 207 and the inoculation ring 201 are driven to rotate by the elastic force of the return spring 305, so that the inoculation ring 201 is in a vertical state and the inoculation ring 201 is not in contact with the inoculation dish 104. The outer surface of the No. 2 rotating shaft 207 is provided with a damping bearing 4, so that the inoculation ring 201 can rotate slowly when rotating, reducing the phenomenon of bringing out the respiratory secretions inside the inoculation dish 104. After the inoculation is completed, the motor 101 stops running and the rubber block 204 stops running under the elastic force of the rubber block 204. By using it, the rack 203 is pushed to move to the right at the upper end of the support frame 1. By setting up the inoculation mechanism 2, with the cooperation of the rotating mechanism 3, the medical staff does not need to hold the inoculation ring 201 to inoculate the respiratory secretions inside the inoculation dish 104, so that during long-term vaccination, the workload of the medical staff can be reduced, and the arm muscles of the medical staff can be avoided in a highly tense state, which is beneficial to ensuring the health of the medical staff. At the same time, the respiratory secretions can be continuously inoculated, so that the inoculation ring 201 can automatically leave the inside of the inoculation dish 104 after the vaccination is completed, which is convenient for removing the inoculated inoculation dish 104 from the upper end of the support platform 103, thereby improving the efficiency of vaccination.

[0034] As an embodiment of the present invention, Figures 2 to 4As shown, the outer surface of the inoculation dish 104 is movably provided with a clamping mechanism 5, and the clamping mechanism 5 includes a slider 501, a third rotating shaft 502, a clamping block 503 and a mounting groove 504. The slider 501 is evenly fixedly installed on the outer surface of the fixing block 301, and the third rotating shaft 502 is evenly fixedly installed on the outer surface of the supporting platform 103. The clamping block 503 is rotatably sleeved on the outer surface of the third rotating shaft 502, and the clamping block 503 cooperates with the inoculation dish 104, and the mounting groove 504 is provided at the lower end of the clamping block 503 close to the supporting platform 103.

[0035] The sliding block 501 is in a T-shaped shape, the mounting groove 504 is inclined, and the mounting groove 504 is slidably connected to the clamping block 503;

[0036] The demoulding mechanism 6 is movably arranged at the upper end of the inner part of the No. 1 rotating shaft 102, and the demoulding mechanism 6 includes a slot 601, a No. 2 spring 602, a movable slot 603, a No. 3 spring 604, a positioning block 605, a positioning slot 606, a connecting rod 607 and an electromagnet 608. The slot 601 is arranged at the upper end of the inner part of the No. 1 rotating shaft 102, and the No. 2 spring 602 is movably inserted at the lower end of the inner part of the slot 601, and the No. 2 spring 602 is fixedly connected to the lower end of the supporting platform 103. At this time, the No. 2 spring 602 is in a compressed state under the pressure of the supporting platform 103, and the movable slot 603 is provided at the front end of the No. 1 rotating shaft 102, and the interior of the movable groove 603 is movably installed with a No. 3 spring 604 and a positioning block 605 from front to back, wherein the No. 3 spring 604 is fixedly connected to the positioning block 605, the positioning groove 606 is provided at the lower end of the front end of the supporting platform 103, and the positioning groove 606 is matched with the positioning block 605, the connecting rod 607 is fixedly installed on the right side of the rear end of the U-shaped plate 302, the electromagnet 608 is fixedly installed on the right side of the connecting rod 607, the positioning block 605 is made of a magnet, and the positioning block 605 and the electromagnet 608 are attracted to each other;

[0037] During operation, with the cooperation of the inoculation mechanism 2 and the rotation mechanism 3, when the inoculation dish 104 is placed on the upper end of the support platform 103 by hand, the hand of the person will give the inoculation dish 104 a downward pressure, so that the inoculation dish 104 can drive the support platform 103 to move toward the inside of the card slot 601, and the support platform 103 will squeeze the positioning block 605 into the inside of the movable slot 603 during the movement. When the positioning slot 606 is connected to the movable slot 603, there is no pressure applied by hand at this time. Under the elastic force of the No. 3 spring 604, the positioning block 605 can be pushed out from the inside of the movable slot 603 and pushed into the inside of the positioning slot 606. At this time, the support platform 103 is fixed in the inside of the card slot 601 and cannot be moved. The support platform 103 moves downward and drives the fixed block 301 to move downward. The slider 501 is evenly fixed on the outer surface of the fixed block 301, so the fixed block 301 can drive the slider 501 to slide inside the mounting groove 504. The mounting groove 504 is inclined. When the slider 501 slides downward, it can drive the clamping block 503 to rotate with the third rotating shaft 502 as the center of the circle, so that the upper end of the clamping block 503 approaches the direction of the inoculation dish 104, and the clamping block 503 can clamp the inoculation dish 104. When the U-shaped plate 302 moves, the connecting rod 607 drives the electromagnet 608 to move with the U-shaped plate 302. When the U-shaped plate 302 moves to the leftmost side, the connecting rod 607 drives the electromagnet 608 to move with the U-shaped plate 302. At this time, the electromagnet 608 has magnetism, and the No. 1 rotating shaft 102 starts to stop rotating. Since the electromagnet 608 and the positioning block 605 attract each other, the electromagnet 608 can move the positioning block 605 out of the interior of the positioning slot 606 and into the interior of the movable slot 603. Under the elastic force of the No. 2 spring 602, the supporting platform 103 is pushed upward to push the inoculation dish 104. At the same time, the fixed block 301 drives the slider 501 to slide upward inside the mounting slot 504, so that the upper end of the clamping block 503 moves away from the inoculation dish 104. It should be noted that the upper right side of the U-shaped plate 302 is hinged, so the upper right side of the U-shaped plate 302 can rotate 90 degrees. When the U-shaped plate 302 is reset, the right side of its upper end can rotate. When the U-shaped plate 302 contacts the fixed block 301, the fixed block 301 will not affect the movement of the U-shaped plate 302 and the connecting rod 607. By setting the clamping mechanism 5 and the demoulding mechanism 6, the inoculation dish 104 can be automatically clamped, so that when the inoculation dish 104 rotates with the support platform 103, the inoculation dish 104 will not move on the upper end of the support platform 103 due to inertia, thereby ensuring the inoculation effect, and the inoculated inoculation dish 104 can be automatically pushed away from the upper end of the support platform 103, which is convenient for medical staff to take the inoculation dish 104 after inoculation, further improving the efficiency of inoculation.

[0038] As an embodiment of the present invention, Figure 2As shown, a disinfection mechanism 7 is movably provided on the left side of the upper end of the support frame 1, and the disinfection mechanism 7 includes a switch 701, a disinfection box 702, a disinfection lamp 703, a through slot 704, a reflector 705 and a mounting frame 706. The mounting frame 706 is fixedly installed on the left side of the upper end of the support frame 1, and the mounting frame 706 is located at the front and rear ends of the rubber block 204. The switch 701 is movably installed on the lower rear end of the disinfection box 702, which is fixedly installed on the mounting frame 706, and the switch 701 cooperates with the support plate 205, and the upper end of the mounting frame 706, the disinfection lamp 703 is symmetrically installed on the front and rear ends of the disinfection box 702, the through slot 704 is opened on the left side of the disinfection box 702, and the disinfection box 702 cooperates with the inoculation ring 201, and the reflector 705 is fixedly installed on both sides of the disinfection box 702;

[0039] During operation, with the cooperation of the inoculation mechanism 2 and the rotating mechanism 3, the inoculation ring 201 will pass through the through groove 704 and enter the interior of the disinfection box 702 when rotating. At the same time, the support plate 205 contacts the switch 701 on the mounting frame 706, thereby triggering the disinfection lamp 703 to turn on. The disinfection lamp 703 disinfects the inoculation ring 201. The reflectors 705 installed on both sides of the disinfection box 702 can increase the disinfection range of the disinfection lamp 703 and enhance the disinfection effect of the disinfection lamp 703. By setting the disinfection mechanism 7, the inoculation ring 201 can be disinfected after the inoculation is completed, so that the inoculation ring 201 will not affect the inoculation effect when inoculating the next respiratory secretion, thereby ensuring the accuracy of the patient's diagnosis. Moreover, the disinfection lamp 703 will only be turned on when the inoculation ring 201 needs to be disinfected, which is beneficial to prolonging the service life of the disinfection lamp 703 and avoiding the waste of resources.

[0040] Working principle:

[0041] During operation, first place the respiratory secretions to be inoculated at the center of the upper end of the inoculation dish 104, fix the inoculation dish 104 on the upper end of the support platform 103, connect the motor 101 to the external power supply, and drive the support platform 103 and the inoculation dish 104 to rotate at the upper end of the support frame 1 with the cooperation of the No. 1 rotating shaft 102. When the inoculation dish 104 is fixed on the upper end of the support platform 103, press the inoculation dish 104 to move downward by hand, and the inoculation dish 104 drives the support platform 103 to move downward. The fixed block 301 is slidably connected to the support platform 103. The fixed block 301 will first move downward with the support platform 103. When the fixed block 301 moves to contact with the No. 1 rotating shaft 102, the support of the No. 1 rotating shaft 102 Under the action, the fixed block 301 will move upward relative to the outer surface of the supporting platform 103. Since the U-shaped plate 302 cooperates with the fixed block 301, when the fixed block 301 moves downward with the supporting platform 103, it will squeeze the U-shaped plate 302 to move downward, thereby pulling the connecting rope 304. At this time, the connecting rope 304 drives the second rotating shaft 207 to rotate, so that the inoculation ring 201 can rotate to contact the inside of the inoculation dish 104, and the motor 101 is connected to the external power supply. The motor 101 drives the first rotating shaft 102 to rotate, and at the same time drives the one-way bearing 201 and the gear 202 to rotate. The gear 202 is meshed with the rack 203. Therefore, when the gear 202 rotates, it will drive the rack 203 to rotate at the upper end of the support frame 1 The inoculation ring 201 and the second rotating shaft 207 are connected to the gear 202 through the fixed plate 206 and the support plate 205, so the inoculation ring 201 will move to the left with the gear 202, thereby spirally inoculating the respiratory secretions inside the inoculation dish 104. When the inoculation ring 201 moves to the leftmost side of the inoculation dish 104, the U-shaped plate 302 is not in contact with the fixed block 301. At this time, the U-shaped plate 302 is driven to move upward under the elastic force of the No. 1 spring 303. At the same time, the No. 2 rotating shaft 207 and the inoculation ring 201 are driven to rotate under the elastic force of the return spring 305, so that the inoculation ring 201 is in a vertical state, the inoculation ring 201 is not in contact with the inoculation dish 104, and the outer surface of the No. 2 rotating shaft 207 is movable. A damping bearing 4 is provided so that the inoculation ring 201 can rotate slowly when rotating, reducing the phenomenon of bringing out the respiratory secretions inside the inoculation dish 104. After the inoculation is completed, the motor 101 stops running, and under the elastic force of the rubber block 204, the rack 203 is pushed to move to the right at the upper end of the support frame 1. The teeth on the rack 203 are connected by a one-way bearing, so the rack 203 will not drive the No. 1 rotating shaft 102 to rotate when moving to the right. Under the cooperation of the inoculation mechanism 2 and the rotating mechanism 3, when the inoculation dish 104 is placed on the upper end of the support platform 103 by hand, the hand of the person will give the inoculation dish 104 a downward pressure, so that the inoculation dish 104 can drive the support platform 103 to move toward the inside of the card slot 601.The support platform 103 will squeeze the positioning block 605 into the movable groove 603 during the movement. When the positioning groove 606 is connected to the movable groove 603, there is no manual pressure at this time. Under the elastic force of the No. 3 spring 604, the positioning block 605 can be pushed out from the inside of the movable groove 603 and pushed into the inside of the positioning groove 606. At this time, the support platform 103 is fixed in the inside of the card slot 601 and cannot move. When the support platform 103 moves downward, it will drive the fixed block 301 to move downward, and the slider 501 is evenly fixed. It is installed on the outer surface of the fixed block 301, so the fixed block 301 can drive the slider 501 to slide inside the mounting groove 504, and the mounting groove 504 is inclined. When the slider 501 slides downward, it can drive the clamping block 503 to rotate with the third rotating shaft 502 as the center, so that the upper end of the clamping block 503 approaches the direction of the inoculation dish 104, and the clamping block 503 can clamp the inoculation dish 104. When the U-shaped plate 302 moves, the connecting rod 607 drives the electromagnet 608 to move with the U-shaped plate 302. When the U-shaped plate 302 moves to the leftmost side, the electromagnet 608 has magnetism, and the No. 1 rotating shaft 102 starts to stop rotating. Since the electromagnet 608 and the positioning block 605 attract each other, the electromagnet 608 can move the positioning block 605 out of the interior of the positioning groove 606 and into the interior of the movable groove 603. Under the elastic force of the No. 2 spring 602, the support platform 103 is pushed upward to push the inoculation dish 104. At the same time, the fixed block 301 drives the slider 501 to slide upward inside the mounting groove 504, so that the clamping The upper end of block 503 moves away from the inoculation dish 104. With the cooperation of inoculation mechanism 2 and rotation mechanism 3, inoculation ring 201 will pass through slot 704 and enter the interior of disinfection box 702 when rotating. At the same time, support plate 205 contacts switch 701 on mounting frame 706, thereby triggering disinfection lamp 703 to turn on. Disinfection lamp 703 disinfects inoculation ring 201. Reflectors 705 installed on both sides of disinfection box 702 can increase the disinfection range of disinfection lamp 703 and enhance the disinfection effect of disinfection lamp 703.
