Description

Technical Field

[0001] This utility model relates to the field of microbial collection technology, specifically a microbial collection device for surface monitoring. Background Technology

[0002] In numerous fields such as food processing, pharmaceutical production, medical treatment, and public health, microbial contamination of object surfaces remains a core risk factor threatening product quality, public health, and production safety. Microorganisms such as bacteria, fungi, and viruses remaining on surfaces can not only cause food spoilage and drug contamination through direct contact and cross-contamination, but may also lead to serious consequences such as hospital infections and public health emergencies. As the first step in the monitoring process, microbial collection, with its sampling efficiency, sample representativeness, and stability, directly determines the accuracy and reliability of subsequent test results.

[0003] Existing methods for collecting microorganisms from surfaces mostly rely on manual operations, such as cotton swab smears and simple imprinting tools, which have many inherent drawbacks: cotton swab sampling is easily affected by differences in operator technique, the sampling area is difficult to standardize, and it is easily contaminated by airborne bacteria during transportation; simple imprinting tools such as contact plates cannot complete the preservation and transportation of samples, making them unsuitable for remote testing scenarios. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a microbial collection device for surface monitoring, which aims to solve the above-mentioned technical problems.

[0005] This utility model relates to a microbial collection device for surface monitoring, comprising a substrate, surface contact strips, a clamping assembly, and a sealing assembly. The substrate has an opening, through which the clamping assembly can enter the substrate. The surface contact strips are symmetrically arranged in two groups on both sides of the substrate, including contact surfaces and non-contact surfaces. The contact surfaces are adhesive, and the non-contact surfaces are smooth. One end of each group of surface contact strips is fixedly connected, and the other end is fixedly connected to a coil spring, the core of which is fixedly connected to the substrate. The clamping assembly includes a connecting rod, one end of which is fixedly connected to a clamp for clamping the fixedly connected end of the two groups of surface contact strips. The sealing assembly includes a compression telescopic rod for compressing the two groups of surface contact strips into a container with the contact surfaces adhering to each other.

[0006] Optionally, the base is slidably connected with a pressure plate, and the end of the connecting rod near the clamp is fixedly connected with a connecting part corresponding to the pressure plate, and the pressure plate can abut against a non-contact surface.

[0007] Optionally, the pressure plate and the connecting part are made of magnetic materials that can attract each other, and the substrate and the pressure plate are also provided with magnets corresponding to the pressure plate at their relative positions.

[0008] Optionally, a cutter is fixedly connected to the substrate, which is used to cut the container to the two sets of surface contact strips.

[0009] Optionally, a holder housing is also fixedly connected between the substrate and the cutter, the holder being used to hold the remaining end of the surface contact strip that has been cut off.

[0010] Optionally, the substrate is provided with a sterile chamber, and the coil spring is located in the sterile chamber.

[0011] This utility model has the following beneficial effects:

[0012] (1) After sampling is completed, the two sets of surface contact strips are pressed together by squeezing the telescopic rod to directly form a sealed container, so that the contact surface of the adhering microorganisms is in a closed space. The outside of the container is a non-contact surface, so the inside will not come into contact with external microorganisms during the transfer to the sterile table or transport box, ensuring the purity of the sample; and the sealed container does not require an additional sealing step, reducing the risk of sample exposure and contamination.

[0013] (2) This device can continuously and repeatedly sample, and the contact strip on the object surface can be used continuously by re-fixing the connection end, without the need for overall replacement, which greatly reduces the consumable cost of a single sampling.

[0014] Of course, any product implementing this utility model does not necessarily need to achieve all of the above advantages at the same time. Attached Figure Description

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see Figures 1-10 As shown, this utility model is a microbial collection device for surface monitoring, including a substrate 1, surface contact strips 2, a clamping assembly, and a sealing assembly. The substrate 1 has an opening, through which the clamping assembly can enter the interior of the substrate 1. The surface contact strips 2 are symmetrically arranged in two groups on both sides of the substrate 1, including a contact surface 22 and a non-contact surface 23. The contact surface 22 is an adhesive surface, and the non-contact surface 23 is a smooth surface. One end of the two groups of surface contact strips 2 is fixedly connected, and the other end is fixedly connected to a coil spring 25. The core of the coil spring 25 is fixedly connected to the substrate 1. The clamping assembly includes a connecting rod 3, one end of which is fixedly connected to a clamp 4 for clamping the fixedly connected end of the two groups of surface contact strips 2. The sealing assembly includes a compression telescopic rod 5 for compressing the two groups of surface contact strips 2 into a container 24 where the contact surfaces 22 are in contact with each other.

[0030] The above embodiments are described below, such as Figure 2 As shown, the clamped portions of the two sets of surface contact strips 2 are bonded together by the adhesive portion of the contact surface 22, or fixedly connected to each other by other means such as insertion or binding, and then clamped by the clamp 4. When the clamp 4 moves, it will move the clamped portion of the surface contact strip 2. The other end of the surface contact strip 2 is fixedly connected to the coil spring 25 and is stretched by the coil spring 25, so that the surface contact strip 2 is in a taut state. The non-contact surface 23 of the surface contact strip 2 will never contact the surface to be collected. Only the contact surface 22 will contact the surface to be collected, and the surface microorganisms of the surface to be collected will be collected by relying on the adhesive surface of its surface.

[0031] The substrate 1 has a groove extending from the opening to the interior of the substrate 1 for guiding the sliding of the clamping assembly. One end of the connecting rod 3 is connected to the clamp 4 to hold the surface contact strip 2, and the other end is also provided with a handle. Pushing the handle causes the connecting rod 3 and the clamp 4 to slide together along the groove, and the clamped surface contact strip 2 moves accordingly. By moving the handle, the contact surface 23 of the surface contact strip 2 can be moved to a position that fits against the surface to be collected. After collection is completed, by pulling back the handle, since the surface contact strip 2 is always in a stretched state, one side of its contact surface 22 will move closer to each other. Then, the sealing assembly can seal the close-to-each contact surface 22 in a container 24. The sealing assembly includes at least one compression telescopic rod 5. Taking the final formed container 24 as a rectangle as an example, the compression telescopic rod 5 of the sealing assembly must compress at least three sides other than its fixedly connected end. Therefore, the output part of the compression telescopic rod 5 can be a rectangle missing one side, or it can be... Figure 7 As shown, the three sides of the rectangle are squeezed by three different extrusion telescopic rods 5. To achieve the squeezing purpose, the extrusion telescopic rods 5 can be squeezed on one side and the other side is the backing plate, or they can be squeezed on one side and both sides by extrusion telescopic rods 5 squeezing each other. The extrusion telescopic rods 5 can be manual telescopic rods or electric telescopic rods.

[0032] Through the above embodiments, a complete sampling process is as follows: Figures 2 to 6 As shown, firstly, the substrate 1 needs to be placed against the plane to be measured. Then, the two sets of surface contact strips 2 are clamped together by the clamping assembly. At this time, the inside of the device is... Figure 2 As shown in position A; then manually push the connecting rod 3, moving the contact surface 22 of the animal surface contact belt 2 until it is in contact with the surface to be measured. At this time, the internal position of the device should be... Figure 3As shown in position B, continuously press down the connecting rod 3 to make the contact surface 22 adhere to the plane to be collected for a period of time to fully collect the data. After the collection is completed, pull the connecting rod 3 to move the clamp 4 away from the plane to be collected. During the movement, the included angle between the two sets of contact surfaces 22 gradually decreases. When the clamp 4 moves to the entrance, the two sets of contact surfaces 22 tend to be parallel. In this embodiment, the extrusion telescopic rod 5 is used as an electric telescopic rod. Start the motor of the extrusion telescopic rod 5. The output end of the extrusion telescopic rod 5 tightly adheres to the corresponding positions of the contact surfaces 22, making them stick together to form a sealed container. At this time, the inside of the device is as follows: Figure 4 As shown at point C; then, the connection between container 24 and surface contact strip 2 is cut in the middle using a tool. The reason for cutting in the middle is that the contact surface of the cut lower half is still adhered, and this part can be directly clamped using clamp 4, eliminating the need for a fixed connection process. It should be understood that during the cutting process, it is only necessary to retain at least a portion of the adhesive part on one side of container 24 to achieve the purpose of the device. Even if all the adhesive parts are retained on one side of container 24, it is only necessary to fix the contact surfaces of the two sets of surface contact strips 2 together again later. After cutting, container 24 is removed from the device, and the contact surface 22 will not come into contact with other microorganisms again before the inhibition operation on the aseptic table. Furthermore, its exterior is a non-contact surface 23, which can be directly moved into the transport box using tools or by hand. Then, clamp 4 clamps the fixed connection part of the two sets of contact surfaces 22 again, and the above steps are repeated to achieve the purpose of repeated sampling.

[0033] Optionally, the base 1 is slidably connected to a pressure plate 6, and the end of the connecting rod 3 near the clamp 4 is fixedly connected to a connecting part 7 corresponding to the pressure plate 6, so that the pressure plate 6 can abut against the non-contact surface 23.

[0034] like Figure 2 As shown, the pressure plate 6 is used to increase the contact area between the contact surface 22 and the sampling plane, thereby improving the sampling efficiency. Therefore, the length of the contact surface 2 on the side where the pressure plate 6 is located is less than the length of the contact surface 2 on the object surface 2, so as to press down the contact surface 2. In this embodiment, the pressure plate 6 may not rise together with the connecting part 7 as it is pressed down, depending on the different connection relationships. If they are only in contact with each other, the connecting part 7 will only rise by itself. If they are connected by magnetic connection, buckle, or other means that the force reaches the threshold and then disconnects, they will rise together until they reach the top of the sliding stroke of the pressure plate 6 and receive a greater relative force to separate from each other. However, since the contact surface 2 is always in a stretched state, the pressure plate 6 will still be carried by the contact surface 2 to the top of its sliding path, so that the contact surface 22 does not contact the sampling plane in the non-sampling state.

[0035] Optionally, the pressure plate 6 and the connecting part 7 are made of magnetic materials that can attract each other, and the base 1 and the pressure plate 6 are also provided with magnets 11 corresponding to the pressure plate 6 at their relative positions.

[0036] Through the above-mentioned device, such as Figure 2 As shown, when the pressure plate 6 is pressed down by the connecting part 7, the downward pressure overcomes the magnetic force between the pressure plate 6 and the magnet 11, and continues to move downward to the bottom to complete the collection. After that, the connecting part 7 retracts, and the pressure plate 6 is pulled upward together by the relative magnetic force between the connecting part 7 and the pressure plate 6. When the pressure plate 6 reaches the highest point of the sliding stroke, the pressure plate 6 no longer slides. The connecting rod 3 continues to be pulled, and the connecting part continues to move upward after overcoming the relative magnetic force between the connecting part 7 and the pressure plate 6. At this time, the connecting part 7 and the pressure plate 6 are disconnected, and the pressure plate 6 and the magnet 11 are magnetically attracted to each other, ensuring that the pressure plate 6 does not slide down on its own.

[0037] Optionally, the substrate 1 is fixedly connected to a cutter 8, which is used to cut the container 24 to the two sets of surface contact strips 2.

[0038] Through the above-mentioned device, such as Figure 5 As shown at point D, the cutter 8 includes an electrically or manually driven connecting rod and a stop block arranged on the other side of the container 24. The stop block can be fixedly connected to a telescopic rod and move toward the part to be cut, or it can be fixed in place. In this embodiment, the connecting rod is electrically driven and the stop block is fixed in place. The end of the connecting rod is a cutting head, and the cutting edge of the cutting head is aligned with the part of the container 24 that needs to be cut with the two sets of surface contact strips 2. When cutting is required, the motor switch is turned on, which drives the connecting rod to move so that the cutting head presses against the part to be cut. The other side of the part to be cut abuts against the stop block, and finally the part to be cut is cut off. The cutter 8 is integrally connected with the base 1, eliminating the need to use external tools.

[0039] Optionally, a housing of a clamp 9 is also fixedly connected between the base 1 and the cutter 8, the clamp 9 being used to clamp the remaining end of the surface contact strip 2 that has been cut off.

[0040] Through the above-mentioned device, such as Figure 6 Middle E and Figure 9As shown, the clamp 9 includes a base and an output clamping part. The base of the clamp 9 can drive the output clamping part. The clamp 9 is located at one end of the remaining portion of the cut surface contact strip 2, and the other end is provided with another clamp 9 or abutment. Similar to the cutter 8, the clamp 9 can also be driven manually or electrically. In this embodiment, the clamp 9 is driven electrically, with two clamps 9 at each end of the cut surface contact strip 2. When it is necessary to cut the connection between the container 24 and the surface contact strip 2, the motors of the two clamps 9 are started. The output clamping parts of the two clamps 9 squeeze and abut from both sides of the part to be cut, completing the clamping of the part to be clamped. The holding part can select the lower half of the connection between the surface contact strip 2 and the container 24 for clamping, ensuring the clamping effect while providing a stable cutting surface for the cutter 8. After cutting, the output clamping part continues to clamp the remaining part of the cut surface contact strip 2. At this time, the clamp 4 can be used for clamping. In one embodiment, the clamping part of the clamp 9 has two output clamping parts, distributed at both ends along the width direction of the surface contact strip 2. During clamping, both ends of the surface contact strip 2 in the width direction are clamped, and the middle part is left empty. At this time, the clamp 4 can directly align with the surface contact strip 2 that extends into the middle empty space of the output clamping part of the clamp 9 for clamping. At this time, the positional relationship of the devices should be as follows. Figure 6 China E and Figure 9 As shown, the next data collection can be performed quickly.

[0041] Optionally, the substrate 1 is provided with a sterile chamber 10, and the coil spring 25 is located in the sterile chamber 10.

[0042] With the above-mentioned device, the sterile room 10 uses ultraviolet sterilization. The outlet of its surface contact belt 2 has a sealing strip to prevent external microorganisms from entering or leaving. The advantage of using ultraviolet sterilization is that it can be turned on for a long time and will not leave sterilization substances on the contact surface 22, thus affecting subsequent microbial collection.
