Description

Technical Field

[0001] This utility model relates to the field of adhesion performance testing technology, and in particular to an adhesion performance testing comparison device. Background Technology

[0002] Medical hydrogels are polymeric materials with a three-dimensional network structure containing a large number of hydrophilic groups. They can absorb a large amount of water and maintain their shape. Due to their good biocompatibility, biodegradability, and controllable physicochemical properties, medical hydrogels have been widely used in the medical field. Medical hydrogels can be used in many fields such as drug delivery, tissue engineering, wound dressings, and biosensors. In wound dressings, medical hydrogels can absorb exudate, maintain wound moisture, prevent bacterial infection, and promote wound healing. In addition, medical hydrogels can also be used as drug carriers to load drugs with hemostatic, antibacterial, and anti-inflammatory effects, thereby enhancing the wound treatment effect.

[0003] The adhesion between medical hydrogels and skin is an important performance indicator in medical applications. Good adhesion ensures that the hydrogel adheres firmly to the wound surface, preventing it from falling off due to accidental collisions or friction, thus guaranteeing the continuity and stability of its therapeutic effect. In addition, adhesion also affects the hydrogel's ability to absorb wound exudate and its protective effect on the wound. Therefore, testing the adhesion between medical hydrogels and skin is of great significance. In specific tests, the medical hydrogel is usually attached to a base material, typically pigskin, to simulate the environment of human skin. Then, a tensile force is applied to the medical hydrogel, and the force required for the hydrogel to separate from the base material is measured. In this way, the adhesion strength of the medical hydrogel can be quantitatively evaluated, thereby providing a scientific basis for the formulation optimization and application of medical hydrogels.

[0004] Currently, tensile testing experiments on medical hydrogels are mainly conducted under conventional environmental conditions. However, the data obtained by this testing method is relatively limited and cannot fully reflect the actual performance of medical hydrogels in different environments. In medical applications, medical hydrogels often need to be used in humid or liquid environments, such as when there is a lot of exudate from a wound. Therefore, the lack of equipment for comparative experiments in water-containing environments limits the accuracy and reliability of experimental data.

[0005] To address the aforementioned issues, this application proposes an adhesion performance experimental comparison device. Utility Model Content

[0009] The bottom of the experimental chamber is equipped with a first cylinder, and the drive end of the first cylinder is equipped with a loading component located inside the experimental chamber. The loading component is used to load medical hydrogel. The loading component is driven by the first cylinder to move up and down and sequentially enter and exit the natural chamber, the spray chamber and the water storage chamber.

[0010] The test chamber is equipped with a tensioning member, which is used to perform a tensile test on the medical hydrogel loaded on the loading device.

[0011] Preferably, the loading component includes a loading tray, a U-shaped block, and an adjustment part. The loading tray is placed inside the experimental chamber, and a pigskin base is fixed to the top of the loading tray. The pigskin base is used to adhere the medical hydrogel.

An adjustment part for adjusting the deflection angle of the fixing block is installed on the U-shaped block. The U-shaped block is connected to a first cylinder, which drives the loading tray to move up and down.

[0012] Preferably, the adjusting part includes a screw and a nut, the U-shaped block has openings on both sides, the fixing block has screws fixed on both sides, the two screws pass through the two openings respectively, the two screws are threaded with nuts, and the two nuts are pressed against the two sides of the U-shaped block respectively.

[0013] Preferably, the annular spraying component includes an annular tube, which is fixed inside the spraying chamber and connected to a water supply component. A spraying channel for the loading component to pass through is formed inside the annular tube, and multiple spray holes are formed around the inner wall of the annular tube.

[0014] Preferably, the water supply component includes a water pump, which is located on one side of the experimental chamber. The outlet of the water pump is connected to a water supply pipe, and one end of the water supply pipe is connected to a diversion pipe. A first conduit and a second conduit passing through one side of the experimental chamber are connected to the diversion pipe. The first conduit is connected to an annular pipe, and a second valve is installed on the first conduit. The second conduit communicates with the water storage chamber inside the experimental chamber, and a third valve is installed on the second conduit.

[0015] Preferably, the tensioning member includes a mounting frame, a second cylinder, a shaft block, and a mechanical claw. The mounting frame is mounted on the edge of the top of the experimental chamber, the second cylinder is mounted on the top of the mounting frame, the drive end of the second cylinder is connected to the shaft block located above the loading member, the bottom of the shaft block is connected to the mechanical claw, and a pressure sensor is connected between the shaft block and the mechanical claw.

[0016] Preferably, the bottom of the experimental chamber is connected to a drain pipe that communicates with the water storage chamber, and a first valve is installed on the drain pipe.

[0017] Preferably, a controller is mounted on the front of the experimental chamber, and the pressure sensor is electrically connected to the controller.

[0018] The above-mentioned technical solution of this utility model has the following beneficial technical effects:

[0019] 1. By sequentially conducting tensile tests on the medical hydrogel in the natural cavity, spray cavity, and water storage cavity, the actual usage under different humidity and liquid environments is simulated. Specifically, in the natural cavity, the medical hydrogel is adhered to a pigskin substrate. The second cylinder in the tensile component drives the shaft block to move downward, and the mechanical claw at the bottom of the shaft block clamps and stretches the medical hydrogel until it is pulled off the pigskin substrate. The pressure sensor can monitor the tensile force. After the test, the medical hydrogel is re-adhered to the pigskin substrate. The first cylinder drives the loading component to sequentially enter the spray cavity and water storage cavity. In the spray cavity, the water supply component delivers water to the annular spray component, spraying a metered amount of water onto the medical hydrogel, and then the tensile test is performed again. In the water storage cavity, the medical hydrogel is completely submerged in water, and the tensile test is continued. This multi-environment testing method can comprehensively and accurately reflect the mechanical properties of the medical hydrogel under different conditions such as dryness, wetness, and complete immersion, providing more reliable and comprehensive data support for the performance evaluation of medical hydrogel in medical applications.

[0020] 2. Since the medical hydrogel needs to be applied to the skin, its position on the skin may be tilted. The nut on the screw can be loosened as needed, moving it away from the U-shaped block. Then, the angle of the loading disc can be adjusted. When adjusting the loading disc angle, the screw on the fixing block at the bottom of the loading disc will rotate accordingly. After adjusting the loading disc angle, the nut on the screw can be tightened to press it against the U-shaped block, thus fixing the position of the loading disc. Then, a tensile test is performed on the medical hydrogel at the tilted angle on the pigskin substrate using a tensile testing device. This design can simulate the tilted state that the medical hydrogel may exhibit on the skin, making the experiment closer to actual application scenarios. This adjustable angle design can more accurately test the tensile properties of the medical hydrogel at different tilt angles, thus providing a more accurate evaluation basis for the performance of the medical hydrogel in actual medical applications when the wound shape is irregular or the position is tilted, further improving the practicality of the experimental data.

[0030] 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 specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0031] like Figure 1-8As shown, the present invention proposes an adhesion performance test comparison device, which includes an experimental chamber 1, an annular spraying component 2, and a water supply component 3.

[0032] The experimental chamber 1 is divided into a natural chamber, a spray chamber and a water storage chamber from top to bottom by two partition frames 101. The annular spray component 2 is installed in the spray chamber, and the water supply component 3 is used to deliver water to the annular spray component 2 and the water storage chamber respectively.

[0033] The bottom of the experimental chamber 1 is equipped with a first cylinder 102. The drive end of the first cylinder 102 is equipped with a loading component 4 located inside the experimental chamber 1. The loading component 4 is used to load medical hydrogel. The loading component 4 is driven by the first cylinder 102 to move up and down and enter and exit the natural chamber, the spray chamber and the water storage chamber in sequence.

[0034] The test chamber 1 is equipped with a tension member 5, which is used to perform a tensile test on the medical hydrogel loaded on the loading member 4.

[0035] The experimental chamber 1, through the natural cavity, spray cavity, and water storage cavity formed by the partition frame 101, provides three different environments for the experiment. The water supply component 3 can respectively deliver water to the annular spray component 2 to simulate a humid environment and inject water into the water storage cavity to simulate a completely immersed environment. The first cylinder 102 drives the loading component 4 to move up and down, realizing the switching of the loading component 4 between the three chambers, ensuring that the medical hydrogel can be tested in different environments. The stretching component 5 is used to apply tension to the medical hydrogel in different environments to complete the adhesion performance test. The above design breaks the limitation of traditional testing only in conventional environments. Through multi-chamber switching and multi-environment simulation, it can comprehensively obtain the adhesion data of medical hydrogel in dry, humid, and completely immersed states, providing richer and more practical application scenarios for the performance evaluation of medical hydrogel, and improving the accuracy and reliability of experimental data.

[0036] In a specific embodiment, the loading component 4 includes a loading tray 41, a U-shaped block 42, and an adjustment part 43. The loading tray 41 is placed inside the experimental chamber 1, and a pigskin base 411 is fixed on the top of the loading tray 41. The pigskin base 411 is used to adhere the medical hydrogel. A fixing block 412 is installed at the bottom of the loading tray 41. The fixing block 412 is placed in the middle of the U-shaped block 42. An adjustment part 43 for adjusting the deflection angle of the fixing block 412 is installed on the U-shaped block 42. The U-shaped block 42 is connected to the first cylinder 102 and is driven by it to move the loading tray 41 up and down.

[0037] The pigskin base 411 on top of the loading tray 41 simulates human skin, providing an adhesion carrier for the medical hydrogel. The cooperation between the fixing block 412 and the U-shaped block 42 enables the connection between the loading tray 41 and the first cylinder 102. The adjusting part 43 can adjust the angle of the fixing block 412 in the U-shaped block 42, thereby changing the tilt state of the loading tray 41 and the pigskin base 411, so that the medical hydrogel can be subjected to tensile tests at different tilt angles. The above simulates the actual application of the medical hydrogel at different tilt positions on human skin, avoiding the deviation between traditional horizontal testing and actual use scenarios. It can more accurately test the adhesion performance of the medical hydrogel in the tilted state, providing scientific data support for its application in irregular wounds or tilted skin positions, and further enhancing the practicality of the experimental results.

[0038] In a specific embodiment, the adjusting part 43 includes a screw 431 and a nut 432. Openings are provided on both sides of the U-shaped block 42, and screws 431 are fixed on both sides of the fixing block 412. The two screws 431 pass through the two openings respectively, and nuts 432 are threaded onto both screws 431. The two nuts 432 are pressed against both sides of the U-shaped block 42 respectively. When it is necessary to adjust the angle of the loading disc 41, the nuts 432 are loosened to release the fixing block 412. At this time, the loading disc 41 can be rotated, causing the screws 431 to rotate within the openings. After adjusting to the target angle, the nuts 432 are tightened, pressing the nuts 432 against both sides of the U-shaped block 42, thus limiting the angle of the fixing block 412 and the loading disc 41.

[0039] In a specific embodiment, the annular spraying component 2 includes an annular tube 21. The annular tube 21 is fixed inside the spraying chamber and is connected to the water supply component 3. A spraying channel is formed inside the annular tube 21 for the loading component 4 to pass through. Multiple spray holes 22 are opened around the inner wall of the annular tube 21. When the loading component 4 enters the spraying chamber, the water supply component 3 supplies water to the annular tube 21. The water is sprayed out through the multiple spray holes 22 around the inner wall of the annular tube 21. Since the spray holes 22 are distributed along the annular shape, they can be sprayed evenly on the surface of the medical hydrogel on the loading component 4 from multiple directions to simulate a humid environment. The above design avoids experimental errors caused by uneven local spraying and ensures that the surface of the medical hydrogel can be evenly contacted with water, more realistically simulating the humid environment in actual applications. At the same time, the design of the spraying channel allows the loading component 4 to pass smoothly through the annular tube 21 without affecting the up and down movement of the loading component 4, ensuring the smoothness of the experimental process.

[0040] In a specific embodiment, the water supply component 3 includes a water pump 31, which is located on one side of the experimental chamber 1. The water outlet of the water pump 31 is connected to a water supply pipe 32, and one end of the water supply pipe 32 is connected to a diversion pipe 33. A first conduit 34 and a second conduit 35 passing through one side of the experimental chamber 1 are connected to the diversion pipe 33. The first conduit 34 is connected to an annular pipe 21, and a second valve 341 is installed on the first conduit 34. The second conduit 35 is connected to the water storage chamber inside the experimental chamber 1, and a third valve 351 is installed on the second conduit 35.

[0041] After the water pump 31 is started, the water source is transported to the diversion pipe 33 through the water supply pipe 32. The diversion pipe 33 divides the water source into two paths, which are transported through the first conduit 34 and the second conduit 35 respectively. When water needs to be supplied to the annular spray element 2, the second valve 341 is opened and the third valve 351 is closed. The water source enters the annular pipe 21 through the first conduit 34. When water needs to be supplied to the water storage chamber, the third valve 351 is opened and the second valve 341 is closed. The water source flows into the water storage chamber through the second conduit 35. The above design realizes that a single water supply element 3 supplies water to the annular spray element 2 and the water storage chamber separately, which simplifies the device structure and reduces equipment costs.

[0042] In a specific embodiment, the tensioning member 5 includes a mounting frame 51, a second cylinder 52, a shaft block 53, and a mechanical claw 54. The mounting frame 51 is mounted on the top edge of the experimental chamber 1, the second cylinder 52 is mounted on the top of the mounting frame 51, the drive end of the second cylinder 52 is connected to the shaft block 53 located above the loading member 4, the bottom of the shaft block 53 is connected to the mechanical claw 54, and a pressure sensor 531 is connected between the shaft block 53 and the mechanical claw 54.

[0043] When a tensile test is required, the second cylinder 52 drives the shaft block 53 to move downward, causing the mechanical claw 54 to approach the medical hydrogel on the loading component 4. After the mechanical claw 54 clamps the medical hydrogel, the second cylinder 52 drives the shaft block 53 to move upward, applying a tensile force to the medical hydrogel. The pressure sensor 531 monitors the magnitude of the tensile force in real time during the tensile process and transmits the data to the relevant equipment.

[0044] In a specific embodiment, the bottom of the experimental chamber 1 is connected to a drain pipe 103 that communicates with the water storage chamber, and a first valve 1031 is installed on the drain pipe 103. When the water in the water storage chamber needs to be discharged, the first valve 1031 is opened, and the water in the water storage chamber is discharged through the drain pipe 103 under the action of gravity. When the water storage chamber needs to store water, the first valve 1031 is closed to prevent water leakage.

[0045] In a specific embodiment, a controller 104 is installed on the front of the experimental chamber 1, and the pressure sensor 531 is electrically connected to the controller 104. During the tensile test, the pressure sensor 531 transmits the monitored tensile data to the controller 104 in real time. The controller 104 can process and display the data, and the experimenter can intuitively view the changes in tensile force through the controller 104. At the same time, the controller 104 can also control the working status of components such as the second cylinder 52 according to a preset program.

[0046] The specific working principle of this device is as follows:

[0047] The medical hydrogel to be tested is adhered to the pigskin base 411 on the top of the loading plate 41. According to the experimental requirements, the angle of the loading plate 41 is adjusted by the adjustment part 43. Specifically, the nut 432 on the screw 431 is loosened, the loading plate 41 is rotated to the target angle, and then the nut 432 is tightened to fix it.

[0048] In the initial state, the loading component 4 is located in the natural cavity formed by the partition frame 101 inside the experimental chamber 1. When the tensioning component 5 is activated, the second cylinder 52 on the mounting bracket 51 drives the shaft block 53 to move down, which drives the mechanical claw 54 at the bottom to hold the medical hydrogel. Then, the second cylinder 52 drives the shaft block 53 to move up, applying a pulling force to the medical hydrogel. The pressure sensor 531 between the shaft block 53 and the mechanical claw 54 transmits the real-time monitored pulling force data to the controller 104 on the front of the experimental chamber 1. The controller 104 processes and displays the data until the medical hydrogel falls off the pigskin base 411. The maximum pulling force value at this time is recorded, and the test in the natural cavity environment is completed.

[0049] After the natural cavity test, a new medical hydrogel was re-adhered to the pigskin base 411. The first cylinder 102 was activated, which drove the U-shaped block 42 to move the loading plate 41 down, so that the loading component 4 entered the spraying chamber. The water pump 31 in the water supply component 3 was activated, and the water pump 31 delivered water to the diversion pipe 33 through the water supply pipe 32. The second valve 341 on the first conduit 34 was opened and the third valve 351 on the second conduit 35 was closed. The water source entered the annular pipe 21 of the annular spray component 2 through the first conduit 34 and was evenly sprayed onto the surface of the medical hydrogel through multiple spray holes 22 on the inner wall of the annular pipe 21. After the preset spraying time, the water pump 31 and the second valve 341 were closed. Then, following the same steps as the natural cavity test, the medical hydrogel was subjected to a tensile test through the tensile component 5. The pressure sensor 531 transmitted the data to the controller 104, recorded the experimental data, and completed the test in the spraying chamber environment.

[0050] After the spray chamber test is completed, a new medical hydrogel is replaced. The water pump 31 is started, the third valve 351 is opened and the second valve 341 is closed. The water source flows into the water storage chamber of the test chamber 1 through the second conduit 35 until the water volume in the water storage chamber reaches the preset height. Then the water pump 31 and the third valve 351 are closed. The first cylinder 102 is started to drive the loading component 4 to continue to move down, enter the water storage chamber and completely immerse the medical hydrogel in water. Then, according to the above tensile test steps, a tensile test is performed through the tensile component 5. The data transmitted from the pressure sensor 531 to the controller 104 is recorded to complete the test in the water storage chamber environment.

[0051] After all environmental tests are completed, open the first valve 1031 on the drain pipe 103 at the bottom of the experimental chamber 1 to drain the water in the water storage chamber, close the first valve 1031, organize the experimental data, compare the adhesion performance data of medical hydrogel in the three environments of natural cavity, spray cavity and water storage chamber, and complete the experimental analysis.

[0052] It should be understood that the above-described specific embodiments of this utility model are merely illustrative or explanatory of the principles of this utility model, and do not constitute a limitation thereof. Therefore, any modifications, equivalent substitutions, improvements, etc., made without departing from the spirit and scope of this utility model should be included within the protection scope of this utility model.
