Description

Technical Field

[0001] This invention relates to the field of homogenization bag opening support technology, specifically to a homogenization bag opening support assembly for microbial testing. Background Technology

[0002] Homogenization bags are professional, disposable, sterile bags used in microbial testing and laboratory sample pretreatment. They are not just simple "bags," but key tools that integrate sample collection, transportation, storage, and homogenization (sample preparation). In microbial testing, homogenization bag opening supports are often used to open the homogenization bags.

[0003] Publication No. CN116215985A discloses a bag opening device for a homogenizing bag, characterized by comprising a base plate and a horizontal pressure plate. A set of side plates are arranged opposite each other on the base plate, with an adjustable distance between the two side plates. A push-pull mechanism is provided on each side plate. The horizontal pressure plate is arranged opposite each other between the side plates and connected to the push-pull mechanism. The height of the push-pull mechanism on the side plate is adjustable. Under the action of the push-pull mechanism, the horizontal pressure plates can move closer or further apart. Adhesive material is provided on the opposite sides of the horizontal pressure plates. The push-pull mechanism includes a push-pull rod and a horizontal guide rod. Long longitudinal sliding holes are provided on the side plates. The push-pull rod passes through and slides through the long sliding holes. The inner end of the push-pull rod is detachably connected to the horizontal pressure plate. Several pairs of guide holes are arranged longitudinally at intervals on the side plates. The horizontal guide rod passes through and slides through the guide holes. The inner end of the horizontal guide rod is detachably connected to the horizontal pressure plate. This device is labor-saving and convenient to use. The homogenizing bag is not easily detached during use, and it has good stability, flexibility, and versatility. In actual experiments, homogenization bags are typically used for sampling and testing microorganisms. The bags are then placed inside a homogenizer and shaken to disperse the microbial sample before subsequent tests and inspections. The top of the homogenization bag usually has a seal and a tear strip. The tear strip prevents external contamination when the bag is not in use, while the seal is used to immediately seal the bag after the microbial sample is poured in to prevent contamination. During use, the tear strip must first be removed, and then the top of the bag is pinched open by both hands. Because hands easily come into contact with the inside of the bag opening when opening it, and microbial samples can easily adhere to bacteria brought in by the hands, some equipment uses an opening support adapted to the homogenization bag to assist in this process. For opening homogenization bags, the most widely used technologies in the prior art are mechanical clamping or adhesive material fixing. However, the mechanical clamping method can easily deform the seal of the homogenization bag, resulting in the seal not being fully engaged and the bag not being able to be sealed properly. On the other hand, using adhesive material to fix the opening can easily leave residual glue on the surface of the homogenization bag, causing the residual glue to stick to the inside of the homogenizer when it is used for homogenization, resulting in incomplete homogenization. Furthermore, the adhesiveness of the adhesive material is greatly affected by temperature and humidity, decreasing at low temperatures and overflowing at high temperatures. As a result, this method is not very effective in fixing when microorganisms need to be tested under specific temperature conditions, and the applicability of the device is low. There is room for further improvement in the stability of the existing equipment for opening homogenization bags. Summary of the Invention

[0014] Beneficial effects 1. This homogenizing bag opening support assembly for microbial testing reduces the risk of deformation of the homogenizing bag seal caused by mechanical clamping, which can lead to incomplete sealing and subsequent failure to seal the bag. Furthermore, it prevents additional material adhesion to the homogenizing bag, reducing the risk of residual adhesive flowing onto the bag surface and sticking to the inside of the homogenizer during homogenization, thus improving the stability of the homogenizing bag opening and making it easier for users to operate.

[0016] 3.

This reduces the possibility of gaps forming between the adsorption head and the seal after the homogenization bag is filled with microbial samples and deformed due to pressure, which would prevent effective adsorption from occurring at the adsorption head. This improves the stability of the device and makes it easier for users to use. Attached Figure Description

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Example Please see Figures 1 to 5A homogenizing bag opening support assembly for microbial testing includes a fixed base plate 1. The fixed base plate 1 has an installation groove 10 at the top center. Opening components 2 are fixedly connected to both sides of the top of the fixed base plate 1. Two first electric push rods are fixedly connected inside the opening components 2. A vacuum adsorption component 20 is fixedly connected to one end of the opening components 2 away from the center of the fixed base plate 1. The vacuum adsorption component 20 consists of a negative pressure fan, a connecting pipe 241, a cyclone collector, and a collection bag. The output end of the vacuum adsorption component 20 is fixedly connected to the connecting pipe 241. The other end of the connecting pipe 241 is fixedly connected to a conveying chamber 240. The other end of the conveying chamber 240 is fixedly connected to a contact chamber 24. An adsorption head 243 is fixedly connected inside the contact chamber 24. A first drive plate 22 is fixedly connected to the output end of the first electric push rod. The first drive plate 22 passes through the opening component 2 and extends to the outside of the opening component 2. A processing chamber 23 is fixedly connected to the extension of the first drive plate 22. A control center 21 is fixedly connected to the surface of one end of the opening component 2. In actual experiments, homogenization bags are typically used for sampling and testing microorganisms. The bags are then placed inside a homogenizer and shaken to disperse the microorganisms before subsequent tests and inspections. The top of the homogenization bag usually has a seal and a tear strip. The tear strip prevents external contamination when the bag is not in use, while the seal is used to immediately seal the bag after the microbial sample is poured in to prevent contamination. During use, the tear strip must first be torn off, and then the top of the bag is pinched open by both hands. In this process, because hands easily come into contact with the inside of the bag opening when opening it, and microbial samples can easily adhere to bacteria brought in by the hands, some equipment uses… An opening bracket adapted to the homogenizing bag is used to assist in the opening process. The most widely used methods in the prior art are mechanical clamping and opening or fixing the opening with adhesive material. However, the above-mentioned mechanical clamping and opening methods are prone to deforming the seal of the homogenizing bag, resulting in the seal not being able to be fully engaged and the homogenizing bag not being able to be sealed subsequently. On the other hand, the method of fixing the opening with adhesive material is prone to leaving residual glue on the surface of the homogenizing bag. When using the homogenizer to beat the homogenizer, the residual glue is easy to stick to the inside of the homogenizer, resulting in incomplete homogenization. Moreover, the adhesiveness of the adhesive material is greatly affected by temperature and humidity. The adhesiveness decreases at low temperatures and overflows at high temperatures. As a result, this method is not very effective in fixing when it is necessary to test microorganisms under specific temperature conditions, and the applicability of the device is low. This invention discloses a homogenization bag opening support assembly for microbial testing. Initially, two opening assemblies 2 are close to each other, with the mounting groove 10 positioned between them. When microbial testing is required and the homogenization bag needs to be opened, the user can manually slide the homogenization bag through the mounting groove 10 between the two opening assemblies 2. Using two first electric push rods on either side of the control center 21, the electric push rods activate, pushing out the first drive plate 22 and moving it. The movement of the first drive plate 22 moves the opening assembly 2 until the contact chamber 24 is tightly pressed against the sealed end of the homogenization bag. Two processing chambers 23 clamp and fix the homogenizing bag. The user can then manually tear off the tear strip on the top of the homogenizing bag to reveal the seal. At this point, the user can activate the vacuum adsorption assembly 20 via the control center 21. The vacuum adsorption assembly 20 generates negative pressure through the delivery pipe 233, which transmits the negative pressure to the adsorption head 243 inside the contact chamber 24 via the connecting chamber 234. This creates negative pressure at the adsorption head 243, performing vacuum adsorption on the sealed portion of the homogenizing bag. The power and support layers inside the control center 21 are activated via a program set within the core control layer. The first electric push rod activates, retracting the first drive plate 22 and causing it to move linearly away from the homogenizing bag. This movement of the first drive plate 22 moves the opening assembly 2, which in turn moves the processing chamber 23 and the contact chamber 24. At this point, the two processing chambers 23 no longer clamp or fix the homogenizing bag, while the movement of the contact chamber 24 causes a portion of the seal adsorbed by the suction head 243 to move as well. The two seals then move linearly away from each other, causing the homogenizing bag to change from a sealed state to an open state. The device completes the opening process of the homogenizing bag. The device uses vacuum adsorption to replace the existing mechanical clamping and adhesive material fixing method. On the one hand, it reduces the possibility that the mechanical clamping method can easily deform the seal of the homogenizing bag, resulting in the seal not being able to be fully engaged and the homogenizing bag not being able to be sealed subsequently. On the other hand, it does not generate additional material adhesion to the homogenizing bag, reducing the possibility that the adhesive material fixing method can easily leave residual glue on the surface of the homogenizing bag, which can easily stick to the inside of the homogenizer when using the homogenizer to beat the homogenizing, resulting in incomplete homogenization. The device improves the stability of the homogenizing bag opening and is easier for users to use. Please see Figures 4 to 6Furthermore, in the above description, a first piston plate 231 is movably connected inside the processing chamber 23. An elastic element 230 is fixedly connected to the bottom of the first piston plate 231. Specifically, the elastic element 230 is a spring, and the other end of the elastic element 230 is fixedly connected to the bottom inner wall of the processing chamber 23. A first through rod 232 is fixedly connected to the top of the first piston plate 231. The first through rod 232 passes through the processing chamber 23 and extends to the top of the processing chamber 23. The extended part of the first through rod 232 is fixedly connected to the bottom of the contact chamber 24. A conveying pipe 233 is fixedly connected to the bottom of the processing chamber 23. After the homogenizing bag is opened in the above steps, the user can pour the microbial sample into the homogenizing bag. During this period, the amount of microbial sample inside the homogenizing bag increases continuously, causing the overall mass of the homogenizing bag to increase continuously. In the above steps, the partition plate 242 partially blocks the conveying area inside the connecting chamber 234. At this time, the adsorption capacity generated at the adsorption head 243 is moderate or even low. Since the mass of the homogenizing bag is low when it is not loaded with microbial sample, the sealing strip is in a free state. At this time, a moderate or small suction force is used to reduce the situation where excessive suction force is applied instantaneously, causing local distortion at the sealing point of the homogenizing bag. When the overall mass of the homogenizing bag increases, the contact chamber 24 and the first through rod 232 move downward under the influence of the weight of the homogenizing bag. The downward movement of the first through rod 232 drives the first piston plate 231 to move downward. The downward movement of the first piston plate 231 causes the elastic element 230 to undergo compressive elastic deformation (the elastic element 230 will only undergo compression when the overall weight of the homogenizing bag exceeds the elastic force of the elastic element 230). (Compression, and in practice the elastic deformation of elastic element 230 is small). At this time, the air pressure inside the processing chamber 23 increases, and the gas inside the processing chamber 23 is transported to the interior of the connecting chamber 234 through the conveying pipe 233. At this time, the air pressure inside the connecting chamber 234 increases, which causes the second piston plate 235 to move downward in the connecting chamber 234. The movement of the second piston plate 235 drives the second through rod 236 to move downward. The downward movement of the second through rod 236 drives the isolation plate to move downward in the connecting chamber 234. The movement of the isolation plate increases the conveying area inside the connecting chamber 234. At this time, the amount of air extracted by the conveying pipe 233 through the connecting chamber 234 and the adsorption head 243 increases, which increases the adsorption capacity of the adsorption head 243 at the sealing point of the homogenized bag. This reduces the situation where the weight of the homogenized bag increases continuously and the weight of the homogenized bag itself is greater than the adsorption capacity of the adsorption head 243, making it difficult for the device to continue to open and fix. This allows the device to change the adsorption capacity according to the change in mass after adding microorganisms to the homogenized bag, making it convenient for users to use. Please see Figures 4 to 6Furthermore, in the above description, a connecting chamber 234 is fixedly connected to one end of the processing chamber 23 away from the center of the fixed base plate 1. A second piston plate 235 is movably connected inside the connecting chamber 234. A second through rod 236 is fixedly connected to the top of the second piston plate 235. The second through rod 236 passes through the connecting chamber 234 and extends to the top outer side of the connecting chamber 234. A partition plate 242 is fixedly connected to the top of the second through rod 236. The partition plate 242 is disposed inside the connecting chamber 234. The other end of the conveying pipe 233 is fixedly connected to the top side of the outer surface of the connecting chamber 234. In the above steps, after the adsorption head 243 increases its adsorption capacity, the suction force generated at the adsorption head 243 is to counteract the downward peeling force generated between the homogenized bag and the contact chamber 24 after the weight of the homogenized bag increases, and to prevent slippage. This increased force acts on the entire contact surface of the sealing strip, which has been smoothed and stably adhered by the initial adsorption force, forming a uniform tensile stress, rather than a localized concentrated stress that causes buckling. Therefore, the enhanced adsorption capacity at the adsorption head 243 will not cause deformation of the seal, ensuring the normal operation of the device. Please see Figures 4 to 7 Furthermore, in the above description, two second electric push rods are fixedly connected inside the opening assembly 2. The second electric push rods are located at the top of the first electric push rod. A second drive plate 25 is fixedly connected to the output end of the second electric push rod. The second drive plate 25 passes through the opening assembly 2 and extends to the outside of the opening assembly 2. Side chambers 26 are fixedly connected to the extension portions of the two second drive plates 25. Used to provide power for the subsequent operation of the device and ensure its normal operation; Please see Figures 7 to 8 Furthermore, as described above, a guide plate 260 is fixedly connected to the top of the side chamber 26. The guide plate 260 is inclined towards the mounting groove 10 and is made of stainless steel. Before the step of filling the homogenization bag with microbial samples as described above, the core control layer program inside the control center 21 is set to activate two second electric push rods. The activation of the two second electric push rods pushes out the second drive plate 25 and drives it to move. The movement of the second drive plate 25 drives the side chamber 26 and the guide frame to move until the guide frame moves to the contact chamber 24. At this time, the guide frame blocks the contact chamber 24 from the top, reducing the possibility of some microbial samples dripping to the contact head and sliding down to the adsorption head 243 during the filling of microbial samples, which would cause contamination at the sealing point of the homogenization bag. After the microbial samples drip from the top to the guide frame, they are guided to the center of the homogenization bag by the guide frame. This reduces the contamination at the sealing point when the device fixes the homogenization bag, improves the stability of the device, and makes it easier for users to use. Please see Figures 7 to 8Furthermore, in the above description, a support frame 261 is fixedly connected to one end of the guide plate 260 away from the center of the fixed base plate 1. Two linear drive assemblies 262 are fixedly connected to the top of the support frame 261. The linear drive assemblies 262 are configured as hydraulic cylinders. An output rod 263 is fixedly connected to the bottom output end of the linear drive assemblies 262. Both output rods 263 penetrate and extend into the interior of the side chamber 26. A push plate 264 is fixedly connected to the extended portion of the two output rods 263. The bottom of the push plate 264 penetrates the side chamber 26 and extends to the bottom outer side of the side chamber 26. An elastic plate 265 is fixedly connected to one end of the push plate 264 away from the center of the fixed base plate 1. After the side chamber 26 moves in the above steps, the core control layer program inside the control center 21 is set to activate two linear drive components 262. The activation of the linear drive components 262 drives the output rod 263 to move. The movement of the output rod 263 causes the push plate 264 and the elastic plate 265 to extend from the connecting chamber 234. The push plate 264 and the elastic plate 265 are both inside the homogenizing bag. At this time, the user can control the extension distance of the second electric push rod to the second drive plate 25 through the control center 21 so that the elastic plate 265 abuts against the sealing point of the inner wall of the homogenizing bag. At this time, the sealing point is controlled by... The elastic plate 265 and the contact chamber 24 are fitted and clamped together to reduce the gap between the adsorption head 243 and the seal. After the elastic plate 265 and the contact chamber 24 clamp the seal, the seal and the adsorption chamber are always kept flat. The adsorption head 243 can maintain the best adsorption capacity to adsorb and fix the homogenization bag. This reduces the possibility of gaps between the adsorption head 243 and the seal after the homogenization bag is filled with microbial samples and deformed by pressure, and the adsorption head 243 can no longer produce effective adsorption. This improves the stability of the device and makes it easier for users to use. Please see Figures 7 to 8 Furthermore, in the above description, the elastic plate 265 is specifically made of highly elastic composite rubber material, and the bottom of the elastic plate 265 is provided with rounded corners; The elastic plate 265 is made of rubber so that it can be held against the seal from inside the homogenizing bag. The rounded corners at the bottom of the elastic plate 265 facilitate its falling from the side chamber 26 and subsequent recovery, ensuring the normal operation of the device. Please see Figures 1 to 3 Furthermore, as described above, the control center 21 comprises a core control layer, a sensing and output layer, a power and execution layer, and an auxiliary and support layer, which are electrically connected to each other. The control center 21 is used to control the normal start and stop of each component inside the opening assembly 2, the processing chamber 23 and the side chamber 26, to ensure the normal operation of the device.
