Description

Technical Field

[0001] This utility model relates to the field of sampling devices, and in particular to a uniform sampling device for collagen dressings. Background Technology

[0002] The collagen dressing uniform sampling device is a highly efficient sampling tool specifically designed for gel-like collagen dressings. It aims to solve the problems of low efficiency, susceptibility to contamination, and poor accuracy associated with traditional manual sampling. Through the collaborative design of an ergonomic handheld component, a spring-driven clamping system, and a sliding protective cover, the device achieves rapid loading and unloading of the fixing ring and accurate sample quantification. Simultaneously, antibacterial materials and a sealed protective structure ensure the cleanliness of the sampling process. Its innovations include a 60% reduction in sampling time, standardized volume control, and anti-contamination design. It is suitable for medical device production quality inspection, laboratory testing, and clinical compliance sampling, significantly improving the automation and standardization of collagen dressing quality control.

[0003] The collagen dressing uniform sampling device achieves precise sampling through a spring-driven clamping system and a standardized fixing ring. Pressing the pressure plate compresses the spring, driving the hinged clamping ring to open and load the fixing ring. After release, the spring returns to its original position, locking the convex ring into the fixing groove. The dressing is then directly scooped out through the fixing ring. The sliding protective cover can slide axially and is locked by a positioning device. During sampling, the clamping end is exposed; when not in use, it closes to form a sealed protection. Combined with an ergonomic handle and quantitative volume control, it achieves efficient, clean, and standardized sampling, suitable for production line quality inspection and laboratory testing needs.

[0004] In the practical application of collagen dressing uniform sampling devices, the sampling cup replacement process presents significant operational challenges. Existing designs require pressing a pressure plate to drive a spring compression while simultaneously supporting the fixing ring with the other hand. This two-handed operation is inefficient in high-frequency sampling scenarios. Furthermore, the sliding protective cover of the protective component must remain fully retracted when replacing the fixing ring, while the spring positioning ball of the positioning device gets stuck due to resistance during sliding. The protective cover position must be repeatedly adjusted to smoothly install and remove the fixing ring. For testing requirements that require frequent switching of fixing rings with different volumes, this not only increases the labor intensity of operators but also risks causing the fixing ring to fall and become contaminated or damage to device components due to operational errors, seriously affecting the continuity and efficiency of production line quality inspection or laboratory testing. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a collagen dressing uniform sampling device, which aims to improve the problem that operators need to perform complicated operations to remove and replace the sampling cup during the use of the equipment.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a collagen dressing uniform sampling device, comprising a connecting block, a rotating shaft fixedly connected inside the connecting block, a connecting plate rotatably connected to the outer wall of the rotating shaft, a fixing ring rotatably connected to one end of the connecting plate rotatably, a sampling component disposed inside the fixing ring rotatably, multiple fixing plates fixedly connected to the outer wall of the fixing ring rotatably, a connecting plate rotatably connected to the outer wall of the rotating shaft, a fixing ring rotatably connected to one end of the connecting plate rotatably, and a fixing component disposed on the outer wall of the fixing ring rotatably.

[0007] The fixing component includes a rotating block, a threaded column, and a nut. One side of the rotating block is fixedly connected to the outer wall of the fixing ring, one end of the threaded column is rotatably connected to the inside of the rotating block, and the inner wall of the nut is threadedly connected to the outer wall of the threaded column.

[0009] The sampling assembly includes a sampling cup and a limiting ring. The outer wall of the sampling cup is slidably connected to the inside of a fixed ring, and the inner wall of the limiting ring is fixedly connected to the outer wall of the sampling cup.

[0010] As a further description of the above technical solution:

[0011] A connecting rod is fixedly connected to one side of the connecting block, and a sliding sleeve is slidably connected to the outer wall of the connecting rod.

[0012] As a further description of the above technical solution:

[0013] The outer wall of the sliding sleeve has multiple fixing grooves, and a handle is fixedly connected to one end of the sliding sleeve.

[0014] As a further description of the above technical solution:

[0015] The connecting rod is internally connected to multiple fixing pins, and each fixing pin is fixedly connected to a limiting plate on its outer wall.

[0016] As a further description of the above technical solution:

[0017] The connecting rod is equipped with multiple springs inside. One end of each spring is fixedly connected to the inside of the connecting rod, and the other end of each spring is fixedly connected to one end of a fixing pin.

[0022] 2. In this utility model, the fixing pin is first pressed down to retract into the connecting rod, while the connecting block is held to pull the connecting rod outward. When the required length is reached, the fixing pin is released so that the rod pops out into the fixing groove under the action of the spring, thus fixing the connecting rod. This achieves the effect of easily adjusting the length of the device to sample dressings at different locations during the use of the device, avoiding the problem of needing to change to different lengths of the device to sample dressings at different locations during the use of the device, thereby improving the convenience of the collagen dressing uniform sampling device.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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] Reference Figure 1 and Figure 2 An embodiment of this utility model provides a collagen dressing uniform sampling device, including a connecting block 1. A rotating shaft 2 is fixedly connected inside the connecting block 1 for rotating a first fixing ring 4 and a second fixing ring 7. A connecting plate 3 is rotatably connected to the outer wall of the rotating shaft 2 for connecting the first fixing ring 4. A first fixing ring 4 is fixedly connected to one end of the connecting plate 3 for fixing a sampling cup 11. A sampling component is provided inside the first fixing ring 4. Multiple fixing plates 5 are fixedly connected to the outer wall of the first fixing ring 4 for restricting the movement of the threaded column 9. A second connecting plate 6 is rotatably connected to the outer wall of the rotating shaft 2 for connecting the second fixing ring 7. A second fixing ring 7 is fixedly connected to one end of the connecting plate 6 for fixing the sampling cup 11. A fixing component is provided on the outer wall of the second fixing ring 7.

[0030] The fixing assembly includes a rotating block 8, a threaded post 9, and a nut 10. One side of the rotating block 8 is fixedly connected to the outer wall of the second fixing ring 7 for connecting the threaded post 9. One end of the threaded post 9 is rotatably connected to the inside of the rotating block 8 for connecting the nut 10. The inner wall of the nut 10 is threadedly connected to the outer wall of the threaded post 9 for connecting the first fixing ring 4 and the second fixing ring 7. The sampling assembly includes a sampling cup 11 and a limiting ring 12. The outer wall of the sampling cup 11 is slidably connected to the inside of the first fixing ring 4 for sampling. The inner wall of the limiting ring 12 is fixedly connected to the outer wall of the sampling cup 11 for limiting the movement of the sampling cup 11.

[0031] Specifically, first, the operator pinches the nut 10 and rotates it counterclockwise at a constant speed until the nut 10 is completely disengaged from the spiral track of the threaded column 9. Then, the threaded column 9 is flipped horizontally outward with the rotating block 8 as the fulcrum. At this time, the first fixing ring 4 and the second fixing ring 7 are unlocked. The operator holds the edges of the two fixing rings with both hands and applies a steady force in the horizontal direction to pull them apart symmetrically, exposing the internally nested sampling cup 11. At this time, the limiting ring 12 on the outer wall of the sampling cup 11 is completely disengaged from the inside of the slide groove, and it can be smoothly removed, completing the disassembly of the sampling cup 11. The entire process requires keeping the hands stable to avoid collisions that could cause component misalignment or sample residue contamination.

[0032] Reference Figure 3A connecting rod 13 is fixedly connected to one side of the connecting block 1 for connecting the front sampling part. A sliding sleeve 14 is slidably connected to the outer wall of the connecting rod 13 for extending the connecting rod 13. Multiple fixing grooves 15 are opened on the outer wall of the sliding sleeve 14 for connecting fixing pins 17. A handle 16 is fixedly connected to one end of the sliding sleeve 14 for holding the device. Multiple fixing pins 17 are slidably connected inside the connecting rod 13 for fixing the length of the device. A limiting plate 18 is fixedly connected to the outer wall of each fixing pin 17 to limit the range of movement of the fixing pin 17. Multiple springs 19 are provided inside the connecting rod 13 to provide elastic force for the fixing pins 17. One end of each spring 19 is fixedly connected inside the connecting rod 13, and the other end of each spring 19 is fixedly connected to one end of the fixing pin 17. The fixing pins 17 are arranged in a symmetrical array and slidably connected inside the connecting rod 13. The outer wall of each limiting plate 18 is slidably connected inside the connecting rod 13.

[0033] Specifically, the operator first presses the fixing pin 17 with their thumb, feeling the slight resistance generated by the compression of the internal spring 19. The fixing pin 17 retracts completely into the hollow cavity of the connecting rod 13. At the same time, the other hand firmly holds the connecting block 1 and pulls the connecting rod 13 horizontally outward along the guide groove with uniform force. When the required working length is aligned with the fixing groove 15, the operator stops applying force. At this time, the spring 19 quickly extends due to the release of pressure, pushing the fixing pin 17 out. The head of the fixing pin 17 accurately engages inside the fixing groove 15, forming a mechanical locking structure. The connecting rod 13 can be felt to be completely fixed through tactile feedback. The entire adjustment process requires the coordination of both hands to avoid overloading the spring 19 or misaligning the fixing pin 17 due to excessively fast pulling.

[0034] Working principle: When using the collagen dressing uniform sampling device, first hold the nut 10 and rotate it to disengage it from the threaded post 9. Then, turn the threaded post 9 to one side to unlock the fixing ring 4 and the fixing ring 7. After that, pull the fixing ring 4 and the fixing ring 7 apart to unlock and remove the sampling cup 11. Then, replace it with a new sampling cup 11. Next, adjust the length of the device. First, press the fixing pin 17 to retract it into the connecting rod 13. At the same time, hold the connecting block 1 and pull the connecting rod 13 outward. When the required length is reached, release the fixing pin 17 so that it pops out into the fixing groove 15 under the action of the spring 19 to fix the connecting rod 13. Then, you can hold the handle 16 to start the sampling work.

[0035] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
