Description

Technical Field

[0001] The invention relates to the technical field of medical gauze strength detection technology, in particular to medical gauze strength detection equipment. Background Art

[0002] Medical gauze is a product made of plain weave of medium and coarse special cotton yarn. It has a sparse structure and has good moisture absorption and dissipation properties after bleaching and degreasing. It is strictly sterilized under high temperature and high pressure and is suitable as a base material for medical bandages and dressings. In order to ensure that it can meet the special strength testing needs of the medical field, the tensile strength of medical gauze needs to be tested.

[0003] The traditional testing method is to cut the medical gauze into the size required for testing, and then clamp the upper and lower ends of the medical gauze sample with the clamps on the tensile testing machine, start the movable crossbeam of the tensile testing machine body, move the movable crossbeam upward, and stretch the medical gauze. When the medical gauze breaks, the control system of the tensile testing machine body will detect abnormal changes in the tension data, thereby triggering an instruction to stop running. At this time, the data is recorded and compared with the standard data to determine whether the medical gauze meets the requirements. However, the medical gauze needs to be cut before testing, and only a single medical gauze sample is tested at a time. In order to ensure the accuracy of the experimental results, multiple medical gauze samples need to be cut and tested one by one. The testing takes a long time and the testing efficiency is low.

[0032] As needed, move a suitable number of mobile brackets 24 toward fixed bracket 21, engage fixing piece 1 22 with fixing piece 26, and engage fixing piece 26 with fixing piece 26. Move unused mobile brackets 24 away from fixed bracket 21, and energize electromagnetic plate 1 25 to magnetically secure mobile bracket 24. Move a suitable number of mobile brackets 2 34 toward fixed bracket 2 31. The fixing part 32 is clamped with the fixing part 4 36, and the fixing part 4 36 is clamped with the fixing part 4 36.

With the cooperation of 38, the part of the medical gauze located on the upper side is fixed, and then the movable crossbeam of the tensile machine body 1 is started, and the movable crossbeam moves upward to stretch the medical gauze. When the medical gauze breaks, the control system of the tensile machine body 1 will detect the abnormal change of the tension data, thereby triggering the instruction to stop running. The data can be recorded at this time. If there is still medical gauze that has not been completely broken, the movable crossbeam continues to move upward until all the medical gauze are broken. After recording all the data, the average is calculated and compared with the standard data to determine whether the tensile strength of the medical gauze meets the standard.

[0040] See Figure 5 The middle part of the right end of the fixed block 1 223 is evenly opened with an arc-shaped groove 1 2231, the middle part of the left end of the fixed block 225 is evenly opened with a matching groove 1 2232 that matches the arc-shaped groove 1 2231, the middle part of the right end of the fixed block 3 263 is evenly opened with an arc-shaped groove 2, and the middle part of the left end of the fixed block 4 265 is evenly opened with a matching groove 2 that matches the arc-shaped groove 2.

[0041] See Figure 1 The number of the second fixing member 26 and the number of the fourth fixing member 36 can be increased as needed. When all the second fixing members 26 and the fourth fixing members 36 are not needed, the unused second fixing members 26 and the fourth fixing members 36 can be moved toward the side away from the first fixing member 22.

[0042] Working principle of the present invention: Step 1: Move an appropriate number of mobile brackets 24 toward the fixed bracket 21 as needed, rotate the card block 1 on the 冂-shaped plate 1 222 and the 冂-shaped plate 2 262 to the corresponding card slot 1, so that the card block 1 and the card slot 1 are clamped together, rotate the card block 2 on the 冂-shaped plate 1 222 and the 冂-shaped plate 2 262 to the corresponding card slot 2, so that the card block 2 and the card slot 2 are clamped together, rotate the card block 3 on the fixed bracket 1 21 and the mobile bracket 1 24 to the corresponding card slot 3, so that the card block 3 and the card slot 3 are clamped together, manually unfold the medical gauze roll, and place one end of the medical gauze between the fixed block 3 263 and the fixed block 4 265 on the far left.

[0043] Step 2: If the number of movable brackets 24 required is not more than two, manually rotate the handle 274 on the leftmost U-shaped plate 262 to drive the rotating rod 273 to rotate, thereby driving the bevel gear 4 272 to rotate, driving the bevel gear 3 271 to rotate, and the bevel gear 3 271 drives the threaded rod 264 to rotate, driving the fixed block 4 265 to move toward the corresponding fixed block 3 263 side until the fixed block 4 265 is tightly attached to the fixed block 3 263, clamping and fixing one end of the medical gauze, and using the arc groove 2 to cooperate with the matching groove 2 to increase the space between the medical gauze and the fixed block 4 265. The medical gauze roll is unfolded upwards, and the unfolded medical gauze is placed in the corresponding fixing piece 4 36 on the upper side for fixing. Then, the medical gauze is unfolded to the right, and the unfolded medical gauze is placed in the fixing piece 3 32 for fixing. The medical gauze is unfolded downwards, and the unfolded medical gauze is placed between the fixing block 1 223 and the fixing block 2 225. The handle 1 234 is manually turned to move the fixing block 225 toward the fixing block 1 223 to clamp and fix the medical gauze. The medical gauze is unfolded to the right, and the unfolded medical gauze is placed in the fixing piece 3 32 to fix it. The unrolled medical gauze is placed between the fixing block 3 263 and the fixing block 4 265 on the right side, and the handle 2 274 is turned to fix the medical gauze. The medical gauze roll is continued to be unfolded upwards, and the unfolded medical gauze roll is placed in the corresponding fixing piece 4 36 on the upper side for fixing. If the number of movable brackets 1 24 required is greater than two, then during the whole process, there is no need to gradually fix the medical gauze parts between the fixing block 1 223 and the fixing block 2 225, between the fixing block 3 263 and the fixing block 4 265, and between the fixing block 3 263 and the fixing block 4 265. When the medical gauze has completed all the paths, it is manually rotated. The leftmost handle 274 drives the rotating rod 273 to rotate. Under the transmission of the belt 1 285, the lower pressure wheel 1 237, the lower pressure wheel 2 277, the moving wheel 284 and the rotating wheel 2 275 rotate synchronously, so that the fixed block 2 225 moves toward the fixed block 1 223, and the fixed block 4 265 moves toward the fixed block 3 263, thereby fixing the part of the medical gauze located on the lower side. At the same time, the fixing part 4 36 is adjusted, and with the cooperation of the transmission part 2 38, the part of the medical gauze located on the upper side is fixed. During the whole process, the medical gauze can be adjusted manually to keep it in a taut state.

[0044] Step 3: Then start the movable crossbeam of the tensile testing machine body 1, and the movable crossbeam moves upward to stretch the medical gauze. When the medical gauze breaks, the control system of the tensile testing machine body 1 will detect the abnormal change of the tension data, thereby triggering the instruction to stop running. At this time, the data can be recorded. If there is still medical gauze that has not been completely broken, the movable crossbeam continues to move upward until all medical gauze are broken. After recording all the data, calculate the average value and compare it with the standard data to determine whether the tensile strength of the medical gauze meets the standard.
