Description

Technical Field

[0001] This utility model belongs to the technical field of microbial experimental equipment, specifically relating to a disposable inoculation loop dispensing device for microbial experiments. Background Technology

[0002] Inoculating loops are essential laboratory equipment in microbiology labs, primarily used for picking colonies and streaking in bacterial testing. Traditional nickel-chromium alloy inoculating loops are relatively soft and thin, easily tearing agar media and requiring a high level of operator skill. Furthermore, they require flaming and cooling after each inoculation, resulting in lengthy waiting times and significantly impacting experimental efficiency. Currently, many microbiology labs use disposable inoculating loops, which are simple to use, require no flaming, and greatly improve experimental efficiency. Disposable inoculating loops have become the most commonly used consumable in bacterial testing labs.

[0003] Currently, disposable inoculation loops are mainly packaged in single-use and multi-use packages. The procedure for using a disposable inoculation loop is to first tear open the packaging by hand, then remove the loop for the experiment. Single-use loops require repeated mechanical tearing of the packaging before each inoculation, which reduces experimental efficiency. While multi-use loops do not require tearing the packaging before each inoculation, it still requires one hand to hold the packaging bag and shake out the individual loop, while the other hand takes the loop for the experiment, which also affects efficiency. Even worse, there is the risk of improper handling, such as operators reaching into the inner packaging to retrieve the loop, increasing the risk of experimental contamination.

[0004] Therefore, designing a disposable inoculation loop dispensing device for microbial experiments to reduce the repeated mechanical operation of tearing packaging and thus improve experimental efficiency, while reducing the probability of experimental contamination due to improper operation, has become a technical problem that urgently needs to be solved by those skilled in the art.

Detailed Implementation

[0033] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0034] Example 1.

[0035] like Figures 1-15 As shown, a disposable inoculation loop dispensing device for microbial experiments includes an instrument housing 1, several inoculation loop boxes 3 inserted into the instrument housing 1 for storing inoculation loops 4, and a loop dispensing mechanism 2 disposed inside the instrument housing 1 for dispensing inoculation loops 4 from the inoculation loop boxes 3; each inoculation loop box 3 is matched with a loop dispensing mechanism 2.

[0036] This invention features a simple structure, a scientific and reasonable design, and is easy to use. It can effectively reduce the repetitive mechanical operations of opening packaging, thereby improving experimental efficiency. At the same time, it can effectively reduce the probability of experimental contamination caused by improper operation. The instrument is small in size and can be placed in a biosafety cabinet for operation.

[0037] Example 2.

[0038] like Figures 1-15 As shown, a disposable inoculation loop dispensing device for microbial experiments includes an instrument housing 1, several inoculation loop boxes 3 inserted into the instrument housing 1 for storing inoculation loops 4, and a loop dispensing mechanism 2 disposed inside the instrument housing 1 for dispensing inoculation loops 4 from the inoculation loop boxes 3; each inoculation loop box 3 is matched with a loop dispensing mechanism 2.

[0039] The ring-out mechanism 2 includes a ring-out platform 201 disposed within the instrument housing 1, a ring-out drive mechanism disposed on the ring-out platform 201, a ring-out plate 202 slidably disposed on the ring-out platform 201 and connected to the ring-out drive mechanism and located at the outlet end of the inoculation ring box 3 for ring-out from the inoculation ring box 3, and a ring-stop plate 203 slidably disposed on the ring-out plate 202 and connected to the ring-out drive mechanism and located at the outlet end of the inoculation ring box 3 for preventing the inoculation ring 4 from falling from the inoculation ring box 3 into the ring-out plate 202.

[0040] Based on Embodiment 1, this Embodiment 2 provides a more preferred structure for the ring-out mechanism 2, specifically: the ring-out mechanism 2 includes a ring-out platform 201 disposed within the instrument housing 1, a ring-out driving mechanism disposed on the ring-out platform 201, a ring-out plate 202 slidably disposed on the ring-out platform 201 and connected to the ring-out driving mechanism and located at the outlet end of the inoculation ring box 3 for ring-out from the inoculation ring box 3, and a ring-stop plate 203 slidably disposed on the ring-out plate 202 and connected to the ring-out driving mechanism and located at the outlet end of the inoculation ring box 3 for preventing the inoculation ring 4 from falling from the inoculation ring box 3 into the ring-out plate 202.

[0041] The ring ejection drive mechanism simultaneously drives the ring ejection plate 202 and the stop ring plate 203 during ring ejection. The ring receiving groove 204 on the ring ejection plate 202 is located at the ring ejection port of the inoculation ring box 3. The inoculation ring box 3 is inserted into the ring ejection table locking groove 223 and the limit stop locking groove 224 through the inoculation ring box insertion slot 5. Then, the card 302 in the locking groove 301 on the inoculation ring box 3 is removed, and the inoculation ring 4 can fall down from the inoculation ring box 3. The bottom inoculation ring 4 falls into the ring receiving groove 204 on the ring ejection plate 202. The ring receiving groove 204 can only hold one inoculation ring 4. When it is necessary to remove the inoculation ring 4, the ring ejection drive mechanism drives the ring ejection plate 202 to slide outward on the ring ejection table 201. The ring receiving groove 204 on the ring ejection plate 202 moves outward simultaneously and is exposed outside the inoculation ring box insertion slot 5. The user can then remove the ring from the ring ejection plate 202. 2. The inoculation ring 4 is retrieved from the upper ring groove 204. During this process, the ring dispensing drive mechanism synchronously drives the stop ring plate 203 to move towards the bottom opening of the inoculation ring box 3. The upper baffle 219 of the stop ring plate 203 blocks the bottom opening of the inoculation ring box 3 to prevent the inoculation ring 4 from falling out of the inoculation ring box 3. When the user removes the inoculation ring 4 from the ring groove 204, the ring dispensing drive mechanism drives the ring dispensing plate 202 to retract to the bottom opening of the inoculation ring box 3. During this process, the stop ring plate 203 is synchronously driven to retract away from the bottom opening of the inoculation ring box 3. When the upper ring groove 204 of the ring dispensing plate 202 is directly below the bottom opening of the inoculation ring box 3, the upper baffle 219 of the stop ring plate 203 just completely leaves the bottom opening of the inoculation ring box 3, and the inoculation ring 4 in the inoculation ring box 3 can fall into the ring groove 204, waiting for the user to retrieve it next time. This invention can effectively reduce the repetitive mechanical operation of tearing packaging, thereby improving experimental efficiency. At the same time, it can also effectively reduce the probability of experimental contamination caused by improper operation. The instrument is small in size and can be placed in a biosafety cabinet for operation.

[0045] The ring-out drive mechanism includes a drive motor 205 mounted on the ring-out stage 201, a reduction gearbox 206 connected to the output end of the drive motor 205, and a ring-out cam 207 and a ring-stop cam 208 respectively connected to the reduction gearbox 206; a rotating shaft 209 is connected to the output end of the reduction gearbox 206, the ring-out cam 207 and the ring-stop cam 208 are respectively connected to the rotating shaft 209, the ring-out plate 202 is connected to the ring-out cam 207, and the ring-stop plate 203 is connected to the ring-stop cam 208.

[0046] Based on Embodiment 2, this Embodiment 3 provides a more preferred structure for the ring-out drive mechanism, specifically: the ring-out drive mechanism includes a drive motor 205 mounted on the ring-out platform 201, a reduction gearbox 206 connected to the output end of the drive motor 205, and a ring-out cam 207 and a ring-stop cam 208 respectively connected to the reduction gearbox 206; a rotating shaft 209 is connected to the output end of the reduction gearbox 206, the ring-out cam 207 and the ring-stop cam 208 are respectively connected to the rotating shaft 209, the ring-out plate 202 is connected to the ring-out cam 207, and the ring-stop plate 203 is connected to the ring-stop cam 208. The drive motor 205 drives the rotating shaft 209 to rotate through the reduction box 206. The exit ring cam 207 and the stop ring cam 208, which are connected to the rotating shaft 209, rotate synchronously with the rotating shaft 209. The exit ring cam 207 is connected to the exit ring plate 202, and the stop ring cam 208 is connected to the stop ring plate 203. Thus, when the drive motor 205 is running, it can drive the exit ring plate 202 and the stop ring plate 203 to run simultaneously. The protruding parts of the exit ring cam 207 and the stop ring cam 208 are staggered, so that the exit ring plate 202 and the stop ring plate 203 can be synchronously inserted and discharged and staggered relative to the exit ring opening of the inoculation ring box 3.

[0047] Example 4.

[0048] like Figures 1-15 As shown, a disposable inoculation loop dispensing device for microbial experiments includes an instrument housing 1, several inoculation loop boxes 3 inserted into the instrument housing 1 for storing inoculation loops 4, and a loop dispensing mechanism 2 disposed inside the instrument housing 1 for dispensing inoculation loops 4 from the inoculation loop boxes 3; each inoculation loop box 3 is matched with a loop dispensing mechanism 2.

[0050] The ring-out drive mechanism includes a drive motor 205 mounted on the ring-out stage 201, a reduction gearbox 206 connected to the output end of the drive motor 205, and a ring-out cam 207 and a ring-stop cam 208 respectively connected to the reduction gearbox 206; a rotating shaft 209 is connected to the output end of the reduction gearbox 206, the ring-out cam 207 and the ring-stop cam 208 are respectively connected to the rotating shaft 209, the ring-out plate 202 is connected to the ring-out cam 207, and the ring-stop plate 203 is connected to the ring-stop cam 208.

[0051] The rotating shaft 209 has a step 210, and the exit ring cam 207 has a shaft hole A211 that matches the large diameter section below the step 210 of the rotating shaft 209. The exit ring cam 207 passes through the large diameter section of the rotating shaft 209. The stop ring cam 208 has a shaft hole B212 that matches the small diameter section above the step 210 of the rotating shaft 209. The stop ring cam 208 passes through the small diameter section of the rotating shaft 209. The rotating shaft 209 is fixed to the exit ring cam 207 and the stop ring cam 208 by keys respectively.

[0052] Based on Embodiment 3, Embodiment 4 provides a more preferred connection structure for the rotating shaft 209 with the exit ring cam 207 and the stop ring cam 208, respectively. Specifically, the rotating shaft 209 is provided with a step 210, and the exit ring cam 207 is provided with a shaft hole A211 that matches the large diameter section below the step 210 of the rotating shaft 209.

The stop ring cam 208 passes through the small diameter section of the rotating shaft 209. The rotating shaft 209 is fixed to the exit ring cam 207 and the stop ring cam 208 respectively by keys. The exit ring cam 207 and the stop ring cam 208 are fixed to the rotating shaft 209 by the same key. Furthermore, the exit ring cam 207 and the stop ring cam 208 are separated from each other by the step 210 on the rotating shaft 209. The structure is simple, the performance is stable and reliable, and the disassembly and maintenance are very convenient.

[0053] Example 5.

[0054] like Figures 1-15 As shown, a disposable inoculation loop dispensing device for microbial experiments includes an instrument housing 1, several inoculation loop boxes 3 inserted into the instrument housing 1 for storing inoculation loops 4, and a loop dispensing mechanism 2 disposed inside the instrument housing 1 for dispensing inoculation loops 4 from the inoculation loop boxes 3; each inoculation loop box 3 is matched with a loop dispensing mechanism 2.

[0055] The ring-out mechanism 2 includes a ring-out platform 201 disposed within the instrument housing 1, a ring-out drive mechanism disposed on the ring-out platform 201, a ring-out plate 202 slidably disposed on the ring-out platform 201 and connected to the ring-out drive mechanism and located at the outlet end of the inoculation ring box 3 for ring-out from the inoculation ring box 3, and a ring-stop plate 203 slidably disposed on the ring-out plate 202 and connected to the ring-out drive mechanism and located at the outlet end of the inoculation ring box 3 for preventing the inoculation ring 4 from falling from the inoculation ring box 3 into the ring-out plate 202.

[0056] The ring-out drive mechanism includes a drive motor 205 mounted on the ring-out stage 201, a reduction gearbox 206 connected to the output end of the drive motor 205, and a ring-out cam 207 and a ring-stop cam 208 respectively connected to the reduction gearbox 206; a rotating shaft 209 is connected to the output end of the reduction gearbox 206, the ring-out cam 207 and the ring-stop cam 208 are respectively connected to the rotating shaft 209, the ring-out plate 202 is connected to the ring-out cam 207, and the ring-stop plate 203 is connected to the ring-stop cam 208.

[0058] Based on Embodiment 3, Embodiment 5 provides a more preferred connection structure between the exiting ring cam 207 and the exiting ring plate 202. Specifically, an annular groove A213 is provided on the outer edge of the top surface of the exiting ring cam 207, and a connecting block A214 is provided on the exiting ring plate 202. The connecting block A214 is provided with a plug rod A215 that is adapted to the annular groove A213, and the plug rod A215 is vertically inserted into the annular groove A213. When the ring-ejecting cam 207 rotates around the pivot 209, the insertion rod A215 slides within the annular groove A213. Since the ring-ejecting plate 202 can only slide along the length of the groove A221 within the limit stop 220, the insertion rod A215 can only move in a straight line relative to or away from the pivot 209. The insertion rod A215 drives the ring-ejecting plate 202 to move in a straight line via the connecting block A214. The ring groove 204 on the ring-ejecting plate 202 can then move to either directly below or away from the ring outlet of the inoculation ring box 3.

[0059] Example 6.

[0060] like Figures 1-15 As shown, a disposable inoculation loop dispensing device for microbial experiments includes an instrument housing 1, several inoculation loop boxes 3 inserted into the instrument housing 1 for storing inoculation loops 4, and a loop dispensing mechanism 2 disposed inside the instrument housing 1 for dispensing inoculation loops 4 from the inoculation loop boxes 3; each inoculation loop box 3 is matched with a loop dispensing mechanism 2.

[0061] The ring-out mechanism 2 includes a ring-out platform 201 disposed within the instrument housing 1, a ring-out drive mechanism disposed on the ring-out platform 201, a ring-out plate 202 slidably disposed on the ring-out platform 201 and connected to the ring-out drive mechanism and located at the outlet end of the inoculation ring box 3 for ring-out from the inoculation ring box 3, and a ring-stop plate 203 slidably disposed on the ring-out plate 202 and connected to the ring-out drive mechanism and located at the outlet end of the inoculation ring box 3 for preventing the inoculation ring 4 from falling from the inoculation ring box 3 into the ring-out plate 202.

[0063] An annular groove B216 is provided on the outer edge of the top surface of the stop ring cam 208. A connecting block B217 is provided on the stop ring plate 203. A plug-in rod B218 adapted to the annular groove B216 is provided on the connecting block B217. The plug-in rod B218 is vertically inserted into the annular groove B216.

[0064] Based on Example 3, Example 6 provides a more preferred connection structure between the stop ring cam 208 and the stop ring plate 203.

The plug-in rod B218 is vertically inserted into the annular groove B216.

[0065] When the stop ring cam 208 rotates around the pivot 209, the connecting block B217 slides within the annular groove B216. Since the stop ring plate 203 can only slide along the length of the groove B222 within the limit stop block 220, the insertion rod B218 can only move in a straight line relative to or away from the pivot 209. The insertion rod B218 drives the stop ring plate 203 to move in a straight line via the connecting block B217, allowing the baffle 219 on the stop ring plate 203 to move directly below or away from the outlet of the inoculation loop box 3. The structure is simple, and the performance is stable and reliable.

[0069] The ring outlet plate 202 is provided with a ring receiving groove 204 that is adapted to the inoculation ring 4. The ring receiving groove 204 is located below the ring outlet of the inoculation ring box 3. The stop ring plate 203 is provided with a baffle 219, which is located below the outlet of the inoculation ring box 3 and above the receiving ring groove 204.

The plug-in structure makes it easy to replace the inoculation ring box 3.

[0082] Example 10.

[0083] like Figures 1-15As shown, a disposable inoculation loop dispensing device for microbial experiments includes an instrument housing 1, several inoculation loop boxes 3 inserted into the instrument housing 1 for storing inoculation loops 4, and a loop dispensing mechanism 2 disposed inside the instrument housing 1 for dispensing inoculation loops 4 from the inoculation loop boxes 3; each inoculation loop box 3 is matched with a loop dispensing mechanism 2.

[0084] The bottom of the inoculation ring box 3 is open, and its cavity contains a row of inoculation rings 4. The bottom of the inoculation ring box 3 is provided with a slot 301, and a card 302 is inserted into the slot 301 to prevent the inoculation rings 4 from falling out of the inoculation ring box 3. The bottom of the instrument housing 1 is provided with a support base 101, and a rotary motor 102 is provided on the support base 101. The instrument housing 1 is mounted on the drive shaft of the rotary motor 102.

[0085] Based on Embodiment 1, this embodiment 10 provides a more preferred structure for the inoculation loop box 3 and the instrument housing 1. Specifically, the inoculation loop box 3 has an open bottom, and its cavity accommodates a row of inoculation loops 4. A slot 301 is provided at the bottom of the inoculation loop box 3, and a card 302 is inserted into the slot 301 to prevent the inoculation loops 4 from falling out of the box. The instrument housing 1 has a support base 101 at its bottom, and a rotary motor 102 is mounted on the support base 101. The instrument housing 1 is mounted on the drive shaft of the rotary motor 102. The card 302 prevents the inoculation loops 4 from falling out of the inoculation loop box 3, preventing them from falling out when changing the box. It also seals the outlet of the inoculation loop box 3, preventing bacterial invasion during replacement. When the rotary motor 102 operates, it drives the entire instrument housing 1 to rotate relative to the support base 101. When different sizes of inoculation loops 4 are needed, the user can easily drive the instrument housing 1 by rotating it with the rotary motor 102, avoiding the need for the user to walk around the instrument housing 1 to retrieve them.

[0086] The loop dispensing platform 201 of this utility model is equipped with a photoelectric sensor 225 and a controller 226. The controller 226 is connected to the photoelectric sensor 225, the drive motor 205, and the rotary motor 102. The controller 226 is also connected to a touch control screen 227 and a buzzer 228. The touch control screen 227 is used for human-machine interaction. When the photoelectric sensor 225 is aligned with the loop slot 204 directly below the loop dispensing port of the loop box 3, it monitors the situation inside the loop slot 204 at that position in real time and transmits the monitoring information to the controller 226 in real time. When the controller 226 receives information that there is no loop 4 in the loop slot 204, it controls the buzzer 228 to issue a warning to remind the user to replace the loop box 3. The controller 226 preferably uses a PLC controller or a microcontroller.

[0087] The top and bottom surfaces of the ring-exit platform 201 of this utility model are each provided with four connecting columns 229, and the ends of the connecting columns 229 are connected to the instrument housing 1 by bolts.

[0088] The instrument housing 1 of this utility model is also provided with a disinfection structure for real-time disinfection of the inoculation ring 4 that falls from the inoculation ring box 3 and the structure in contact with it. The disinfection structure is preferably ozone disinfection. The ozone disinfection structure is an existing technology structure and can be directly installed on the instrument housing 1 for use. The specific structure of the disinfection structure, the ozone concentration during disinfection, the disinfection principle, etc. are not described here.

[0089] The photoelectric sensor 225, controller 226, touch control screen 227, buzzer 228, drive motor 205, and rotary motor 102 used in this utility model are all existing known electrical devices, and all can be purchased and used directly on the market. Their structure, circuit, and control principle are all existing technologies. Therefore, the structure, circuit, and control principle of the photoelectric sensor 225, controller 226, touch control screen 227, buzzer 228, drive motor 205, and rotary motor 102 will not be described in detail here.
