Description
Technical Field
[0001] This utility model relates to the technical field of inoculation loop dispensing equipment, specifically to an inoculation loop dispensing instrument. Background Technology
[0002] Inoculating loops are laboratory tools used in fields such as microbial detection, cell biology, and molecular biology. The inoculating loop structure consists of a loop and a rod connecting the loop; the diameter of the loop is larger than the diameter of the rod. Traditional nickel-chromium alloy inoculating loops are relatively soft and thin, easily tearing agar culture media, requiring a high level of operator skill; furthermore, they require flaming and cooling after each inoculation, resulting in long waiting times and significantly impacting experimental efficiency. Currently, disposable inoculating loops are widely used in microbiology laboratories. They are simple to use, require no flaming, greatly improve experimental efficiency, and have become the most commonly used consumable in bacterial testing laboratories.
[0003] Currently, disposable inoculation loops are mainly packaged in single-loop and multi-loop packaging. For single-loop packaging, the mechanical process of tearing open the packaging is required before each inoculation, reducing experimental efficiency. For multi-loop packaging, although the packaging doesn't need to be torn before each inoculation, the operation of removing each loop from the packaging bag is still necessary, which is also inconvenient and affects experimental efficiency. More importantly, fingers can easily touch other loops when removing them, posing a risk of contamination.
[0004] Chinese patent CN2240936Y discloses a novel sanitary chopsticks box with a quantitative chopstick dispenser. It consists of a box body, a quantitative chopstick dispenser, and a chopstick conveying plate. The box body has a lid and an interior with a sloping or curved surface, and a chopstick channel at the bottom. The quantitative chopstick dispenser consists of a chopstick-dispensing shaft with grooves along its axis, a return spring, and a chopstick-dispensing key; or it consists of a chopstick-dispensing plate with grooves, a return spring, a chopstick-dispensing key, and a positioning plate with a rectangular chopstick-draining opening. The chopstick conveying plate consists of a conveying section, a placement section, and a chopstick-blocking section. This design ensures a constant number of chopsticks dispensed each time by limiting the channel opening size, the groove size on the chopstick-dispensing shaft (or chopstick-dispensing plate), and the distance between the groove and the channel opening. Because the structure of the inoculation loop differs from that of chopsticks, the loop portion of the inoculation loop is directly larger than the rod portion. The abrupt change in size at the transition from the rod portion to the loop portion is significant. The vertical projection area of the loop portion when it is upright is much smaller than that when it is laid flat. Furthermore, the rod portion has a thinner diameter. When using the above structure for single-piece quantitative ring removal, if the chopstick channel opening is set to match the width of the inoculation loop, the state of the loop portion when the inoculation loop slides down cannot be guaranteed (the loop portion may be in an upright, flat, or other states), and the inoculation loop is prone to getting stuck in the chopstick channel opening. If the chopstick channel opening is set too large, it is impossible to accurately allow the inoculation loop to fall into the groove. Therefore, it cannot be used for inoculation loops.

[0044] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0045] like Figures 1 to 6As shown, the inoculation loop dispensing device of this utility model includes at least one loop dispensing system. The loop dispensing system includes a housing 1 and a single loop dispensing mechanism. The housing 1 has a discharge port 12, which is generally rectangular. The housing 1 contains an inoculation loop storage cavity 11 and a dispensing structure for feeding the inoculation loop from the discharge port 12. The bottom of the inoculation loop storage cavity 11 has a downwardly inclined sliding plate 111. The sliding plate 111 includes an inoculation loop rod bearing section 112 and an inoculation loop ring bearing section 113 along its width. The inoculation loop ring bearing section 113 supports the ring portion of the inoculation loop, and the inoculation loop rod bearing section 112 supports the rod portion of the inoculation loop. The feeding drive mechanism includes a feeding drive mechanism and a stepped feeding mechanism 2. The lower end of the stepped feeding mechanism 2 is connected to the lower end of the sliding plate 111, and the upper end is connected to the discharge structure 3, for lifting the material on the sliding plate 111 and sending it to the discharge structure. The stepped feeding mechanism includes at least one lifting step unit 21. The lifting step unit 21 includes a fixed step 211 and a lifting step 212 disposed below the fixed step 211 for lifting an inoculation ring. The lifting step 212 and the fixed step 211 are arranged in a stepped manner along the direction from the sliding plate 111 to the discharge structure 3. The fixed step 211 is fixedly disposed in the box body 1 in a vertical or inclined upward direction, and the lifting step 212 is slidably connected to the box body 1 along the setting direction of the fixed step 211. The feeding drive mechanism is connected to the lifting step 212 to drive the lifting step 212 to slide back and forth in the sliding direction, thereby lifting the inoculation rings on the sliding plate 111 one by one to the discharge structure.
[0046] The loop retrieval system is configured as needed. Since there are currently two main specifications of disposable inoculation loops on the market, this invention includes two sets of loop retrieval systems to accommodate different sizes of inoculation loops. To reduce the size of the instrument, only one loop retrieval system may be used.
[0047] The function of the sliding plate 111 is to allow the inoculation rings in the inoculation ring storage cavity 11 to slide along the sliding plate 111 under the action of gravity, thereby moving them onto the stepped feeding mechanism 2. The specific tilt angle of the sliding plate 111 can be determined experimentally.
[0048] Figure 1 The fixed steps are set at an angle. Figure 6 In the middle, the fixed steps are set vertically.
[0049] When the stepped feeding mechanism includes at least two lifting step units 21, the lifting step units 21 are connected sequentially along the direction from the sliding plate 111 to the discharge structure 3. Through experiments, it has been shown that when the stepped feeding mechanism includes at least two lifting step units 21, the action of multiple lifting steps 212 can better ensure that the stepped feeding mechanism lifts one inoculation ring to the discharge structure at a time.
[0050] Specifically; when the stepped feeding mechanism has only one lifting step unit 21, the lifting step 212 connects with the lower end of the sliding plate 111, and the fixed step 211 connects with the discharge structure; when the stepped feeding mechanism has multiple lifting step units 21, the lifting step 212 of the first (lowest) lifting step unit 21 connects with the lower end of the sliding plate 111, and the discharge structure connects with the last (upper) fixed step 211 (see...). Figure 6 ).
[0051] The inoculation ring picker of this utility model connects the lower end of the stepped feeding mechanism 2 to the lower end of the sliding plate 111. The inoculation ring 7 stored in the inoculation ring storage cavity 11 can automatically slide along the sliding plate 111 onto the stepped feeding mechanism 2 under the action of gravity. The stepped feeding mechanism 2 is composed of a stepped lifting step unit 21 consisting of a fixed step 211 and a lifting step 212 arranged in a stepped shape. The limiting function of the front side (facing the sliding plate) of the fixed step 211 allows the inoculation rings against the front side of the fixed step 211 to be placed along the width of the stepped feeding mechanism. The width of the lifting step 212 is set according to the width of the inoculation ring, so that only one inoculation ring can be placed flat on the top surface of the lifting step 212. Therefore, the lifting step 212 can lift only one inoculation ring at a time when lifting.
[0052] In use, the inoculation loop dispenser of this invention places a certain number of inoculation loops 7 on the sliding plate 111 of the inoculation loop storage cavity 11, with the placement direction of the inoculation loops along the width direction of the sliding plate 111. When an inoculation loop 7 is needed, the feeding drive mechanism is activated, which drives the lifting step 212 to rise and slide, lifting the inoculation loop 7 that has slid from the sliding plate 111 to the top surface of the lifting step 212 onto the discharge structure, and then the discharge structure delivers it out of the box 1 for easy retrieval. Therefore, this invention makes the use of inoculation loops convenient, improves experimental efficiency, and prevents fingers from contacting other inoculation loops (which are located inside the box) when retrieving them, thus reducing the risk of contaminating other inoculation loops 7.
[0053] Because there is a dimensional abrupt change from the rod to the ring of the inoculation ring, and the required support area varies depending on the ring's orientation, while the rod does not have this problem, in order to better ensure that the stepped feeding mechanism 2 can lift one inoculation ring at a time, the optimal configuration in this invention is as follows: Figure 5 As shown, the stepped feeding mechanism is configured corresponding to the inoculation ring rod bearing section 112. With the stepped feeding mechanism configured corresponding to the inoculation ring rod bearing section 112, the ring portion of the inoculation ring sliding onto the stepped feeding mechanism is not restricted by the front side of the fixed step 211, and its placement does not affect the position of the rod. Therefore, it better ensures that the stepped feeding mechanism 2 can lift one inoculation ring at a time.
[0054] The lifting step 212 and the fixed step 211 are arranged in a stepped manner along the direction from the sliding plate 111 to the discharge structure 3. Specifically, the lifting step 212 can be positioned in front of the side of the fixed step 211 facing the sliding plate 111 (see...). Figure 6 With reference to the direction of the fixed step 211 facing the slide plate 111, the lifting step 212 is disposed on one side of the fixed step 211 (see...). Figure 3 , Figure 4 Because the inoculation ring has a small rod diameter, when it is positioned in front of the side of the fixed step 211 facing the sliding plate 111, the thickness of the lifting step 212 needs to be consistent with the rod diameter of the inoculation ring to ensure that only one inoculation ring can be lifted at a time on the top surface of the lifting step 212. However, since the rod diameter of the inoculation ring is small, the thickness of the lifting step 212 is relatively thin, making it difficult to guarantee its strength. Therefore, in this invention, preferably, the lifting step 212 is positioned on the side of the fixed step 211. See also Figure 3 When the lifting step 212 is set on one side of the fixed step 211, the lifting step 212 can extend to the rear side of the fixed step 211. It is only necessary to ensure that the length of the lifting step 212 protruding forward from the fixed step 211 is compatible with the rod diameter of the inoculation ring. The thickness of the lifting step 212 can be set to be thicker, with better strength, and it is not easy to deform during use, which can better ensure the service life.
[0055] like Figure 1 As shown, to facilitate the sliding of the inoculation loop from the lifting step 212 to the top surface of the next fixed step 211, as... Figure 1 As shown, the top surface of the lifting step 212 is inclined relative to the horizontal plane, with the end closer to the discharge structure 3 being the lower end. To facilitate the sliding of the inoculation ring on the top surface of the fixed step 211 onto the lifting step 212 or the discharge structure, the top surface of the fixed step 211 is also inclined relative to the horizontal plane, with the end closer to the discharge structure 3 being the lower end. The specific inclination of the top surfaces of the lifting step 212 and the fixed step 211 can be determined experimentally.
[0056] The feeding drive mechanism can be a pneumatic cylinder, a hydraulic cylinder, or an electric actuator. In this embodiment of the invention, such as… Figure 2As shown, the feeding drive mechanism includes a lifting motor 22, a feeding push rod 24, and a feeding rotating wheel 23 mounted on the housing 1. The lifting motor 22 is connected to the feeding rotating wheel 23. The feeding push rod 24 is used to push the lifting step 212 to slide back and forth in the sliding direction. One end of the feeding push rod 24 is eccentrically hinged to the feeding rotating wheel 23, and the other end is hinged to the lifting step 212. During lifting, the lifting motor 22 is started, which drives the feeding rotating wheel 23 to rotate. Because one end of the feeding push rod 24 is eccentrically hinged to the feeding rotating wheel 23, the feeding rotating wheel 23 can push the lifting step 212 to slide back and forth in the sliding direction through the feeding push rod 24 during rotation. The lifting motor 22 can be a servo motor, stepper motor, or servo motor, etc.
[0057] The discharge structure can be set inside the box, through a discharge trough extending downwards at an inclined angle from the discharge port 12. The lower end of the discharge trough is equipped with a baffle to prevent the inoculation ring from sliding out of the discharge trough. For example... Figure 1 , Figure 2 As shown in the embodiment of this utility model, the discharge structure includes a discharge driving mechanism and a discharge push plate 31 that is connected to the upper end of the stepped feeding mechanism; the discharge port 12 is arranged facing upward; the discharge push plate 31 is vertically slidably disposed in the box body 1 and is arranged correspondingly to the discharge port 12, so that when sliding vertically upward, the upper end can extend out of the box body 1 through the discharge port 12; the upper end of the discharge push plate 31 is provided with an inoculation ring groove 311; the discharge driving mechanism is connected to the discharge push plate 31 to drive the discharge push plate 31 to slide vertically, thereby extending out of the box body 1 or retracting into the box body 1.
[0058] When the stepped feeding mechanism 2 lifts the inoculation ring and sends it into the inoculation ring slot 311, the discharge drive mechanism drives the discharge push plate 31 to slide vertically upward, thus sending the inoculation ring out of the box 1 through the discharge port 12. After the inoculation ring is removed, the discharge drive mechanism drives the discharge push plate 31 to slide vertically downward, causing it to retract into the box 1 and return to its original position for the next discharge.
[0059] In some embodiments, the discharge port 12 is also arranged horizontally, and correspondingly, the discharge pusher plate 31 is also arranged horizontally. Since the feeding drive mechanism adopts the stepped feeding mechanism 2, the discharge port 12 is arranged vertically upward and the discharge pusher plate 31 is arranged vertically, which is more convenient and helps to make the system structure more compact.
[0060] See Figure 1 In order to better secure the inoculation ring in the inoculation ring slot 311, the height of the slot wall on the side of the ring slot 311 away from the feeding drive mechanism can be set higher than the height of the slot wall on the side closer to the feeding drive mechanism.
[0061] The discharge drive mechanism can also be a pneumatic cylinder, a hydraulic cylinder, or an electric actuator. In this embodiment of the invention, Figure 2 As shown, the discharge drive mechanism includes a discharge drive motor (not shown in the figure), a discharge push rod 32, and a discharge wheel 33 mounted on the box body 1. The output shaft of the discharge drive motor is connected to the discharge wheel 33. One end of the discharge push rod 32 is eccentrically hinged to the discharge wheel 33, and the other end is hinged to the discharge push plate 31. During discharge, the discharge drive motor is started, driving the discharge wheel 33 to rotate. Because one end of the discharge push rod 32 is eccentrically hinged to the discharge wheel 33, and the other end is hinged to the discharge push plate 31, the discharge wheel 33 can push the discharge push plate 31 to slide vertically back and forth through the discharge push rod 32 during rotation, thereby causing the discharge push plate to extend out of the box body 1 or retract into the box body 1. The discharge drive motor can also be a servo motor, stepper motor, or servo motor, etc. In this utility model, the discharge drive motor is a servo motor.
[0062] When the instrument is powered on, the start and stop control of the lifting motor 22 and the discharge drive motor can be manually controlled or automatically controlled by the controller. When the discharge drive motor is a servo motor, stepper motor, or servo motor, the motor itself has an angle sensor to measure its transmission angle. Given that the stroke of the discharge push plate 31 is determined, the above structure can obtain the corresponding position of the discharge push plate 31 based on the rotation angle of the control motor. Therefore, in order to facilitate the automatic control of the lifting motor 22 and the discharge drive motor by the controller and make the operation of the equipment more convenient, in this embodiment of the invention, the ring retrieval system also includes a controller 8 and an inoculation ring detection sensor for detecting whether an inoculation ring exists in the inoculation ring slot 311. The inoculation ring detection sensor is electrically connected to the controller, and the controller 8 is electrically connected to the lifting motor 22 and the discharge drive motor. The inoculation ring detection sensor transmits the detection signal of whether an inoculation ring exists in the inoculation ring slot 311 to the controller. The controller controls the corresponding actions of the lifting motor 22 and the discharge drive motor according to the signal from the inoculation ring detection sensor, realizing one-button ring retrieval (simply turn on the instrument power button). Specifically, when the inoculation loop detection sensor detects an inoculation loop in the inoculation loop slot 311, the controller controls the discharge drive motor to rotate a certain angle to deliver and hold the inoculation loop out of the box. Simultaneously, it controls the lifting motor 22 to stop. When the inoculation loop detection sensor detects that the inoculation loop in the inoculation loop slot 311 has been removed (no inoculation loop exists), the controller controls the discharge drive motor to reverse a certain angle, retracting the discharge push plate 31 back to its original position. Simultaneously, it controls the lifting motor 22 to lift the inoculation loop into the inoculation loop slot 311. During operation, the position information of the discharge push rod 32 is determined by the information fed back to the controller from the angle sensor on the discharge drive motor. The controller can be a PLC controller or a microcontroller, etc. The inoculation loop detection sensor can be a photoelectric sensor; in this embodiment, a diffuse reflection laser sensor is used.
[0063] If the discharge drive motor is a regular motor without position feedback, it is understandable that a position detection sensor for measuring the position of the discharge push plate 31 needs to be installed on the box to facilitate the controller's understanding of the position of the discharge push plate 31.
[0064] To make the instrument more convenient to use, such as Figure 2As shown, the loop removal system of this utility model also includes a prompter (not shown) and a touch screen 9 for inputting the initial number of inoculation loops (placed in the loop storage cavity 11) and displaying the remaining number of inoculation loops (in the loop storage cavity 11). The controller 8 is electrically connected to the touch screen 9 to obtain the initial number of inoculation loops from the touch screen 9 and output a signal indicating the remaining number of inoculation loops to the touch screen 9, so that the touch screen 9 displays the remaining number of inoculation loops. The controller 8 is also electrically connected to the prompter to send a signal to the prompter when the remaining number of inoculation loops is less than a set value, causing the prompter to issue a prompt signal to remind the user to insert a new inoculation loop. The prompter can be a voice prompter or a light prompter. Specifically, after the inoculation loop detection sensor detects that an inoculation loop in the loop slot 311 has been removed once, the controller decrements the number of inoculation loops by one, thereby obtaining the remaining number of inoculation loops.
[0065] like Figure 1 , Figure 7 As shown, in this utility model, the ring retrieval system further includes an inoculation ring storage box 4. The inoculation ring storage box 4 is inserted into the box body 1. The side of the inoculation ring storage box 4 is provided with an inoculation ring dropping hole 41 extending along the width direction of the sliding plate 111 and located above the sliding plate 111. An opening and closing plate 42 is provided on the outer side of the inoculation ring dropping hole 41, which cooperates with the inoculation ring dropping hole 41 to open and close the inoculation ring dropping hole 41. The opening and closing plate 42 is slidably connected to the inoculation ring storage box 4 along the insertion direction of the inoculation ring storage box 4. The box body 1 is provided with a limiting structure that cooperates with the opening and closing plate 42. During the process of inserting the inoculation ring storage box 4 into the box body 1, the limiting structure cooperates with the opening and closing plate 42, so that the opening and closing plate slides relative to the inoculation ring storage box 4, thereby opening the inoculation ring dropping hole 41. The limiting structure is generally a protrusion structure provided on the box body that cooperates with the opening and closing plate 42.
[0066] The length of the inoculation ring discharge hole 41 is set according to the length of the inoculation ring so that the inoculation ring placed flat in the inoculation ring storage box 4 can fall out of the inoculation ring discharge hole 41. The inoculation ring discharge hole 41 extends along the width direction of the slide plate 111 and is located above the slide plate 111. Therefore, the inoculation ring falling out of the inoculation ring discharge hole 41 can fall into the slide plate 111, and the falling and placing direction is consistent with the width direction of the slide plate 111, so as to facilitate its sliding down the slide plate 111 and onto the stepped feeding mechanism.
[0067] Because the inoculation loop must be sterile and cannot be contaminated, the above structure allows the inoculation loop to be placed in the inoculation loop storage box 4 and sterilized in a sterilization device before being inserted into the box body. Then, the inoculation loop is placed into the inoculation loop storage cavity through the inoculation loop storage box 4, which reduces the risk of contamination during the placement of the inoculation loop into the storage cavity. The opening and closing plate 42 is designed to cooperate with the limiting structure, opening the inoculation loop drop hole 41 during insertion into the box body, making the opening and closing plate 42 easier to open.
[0068] like Figure 1 , Figure 8 As shown, this utility model also includes a base 5, on which a turntable 51 with its axis arranged vertically is mounted, and the ring-retrieving system is mounted on the turntable 51. Thus, the orientation of the box 1 can be adjusted by rotating the turntable according to actual conditions, such as the operator's position, thereby adjusting the position of the discharge port 12 to facilitate the operator's retrieval of the inoculation ring.
[0069] The turntable 51 can be driven manually or by an electric motor. Furthermore, it includes a position adjustment motor 52, which is connected to the turntable 51 to drive its rotation. The specific transmission method can employ conventional transmission connections such as gears or chain drives.
[0070] The inoculation loop storage cavity 11 of this invention is equipped with an ultraviolet sterilization lamp 6 and / or an ozone sterilization device to sterilize the inoculation loop.
