Description

Technical Field

[0001] The invention relates to the technical field of medical gauze strength detection, in particular to a medical gauze strength detection device. 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 moisture dissipation properties after bleaching and degreasing. It is strictly sterilized at high temperature and high pressure and is suitable as a base material for medical bandages and coverings. 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 the test, 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.

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.

An arc-shaped groove two is evenly formed in the middle of the right end of the third fixing block 263, and a mating groove two that matches the arc-shaped groove two is evenly formed in the middle of the left end of the fourth fixing block 265.

[0041] Refer to Figure 1 , the number of the second fixing members 26 and the number of the fourth fixing members 36 can both be increased as needed. When not all the second fixing members 26 and the fourth fixing members 36 are needed, the unused second fixing members 26 and the fourth fixing members 36 can be toggled away from the first fixing member 22.

[0042] The working principle of the present invention: First step: Toggle the appropriate number of the first moving brackets 24 towards the first fixing bracket 21 as needed, rotate the first clamping blocks on the U-shaped plate one 222 and the U-shaped plate two 262 to the corresponding first clamping grooves respectively, so that the first clamping blocks are clamped with the first clamping grooves. Rotate the second clamping blocks on the U-shaped plate one 222 and the U-shaped plate two 262 to the corresponding second clamping grooves respectively, so that the second clamping blocks are clamped with the second clamping grooves. Rotate the third clamping blocks on the first fixing bracket 21 and the first moving brackets 24 to the corresponding third clamping grooves respectively, so that the third clamping blocks are clamped with the third clamping grooves. Manually unfold the medical gauze roll and place one end of the medical gauze between the leftmost third fixing block 263 and the fourth fixing block 265.

[0043] Step 2: If the number of the first movable brackets 24 required is no more than two, at this time, manually rotate the handle two 274 on the leftmost U-shaped plate two 262, drive the rotating rod two 273 to rotate, thereby driving the bevel gear four 272 to rotate, driving the bevel gear three 271 to rotate, the bevel gear three 271 drives the threaded rod two 264 to rotate, driving the fixed block four 265 to move towards the corresponding fixed block three 263 until the fixed block four 265 is in close contact with the fixed block three 263, clamping and fixing one end of the medical gauze. By using the cooperation between the arc-shaped groove two and the cooperation groove two, the contact area between the medical gauze and the fixed block four 265 and between the medical gauze and the fixed block three 263 is increased, increasing the frictional resistance it receives. Continue to unfold the medical gauze roll upwards, put the unfolded medical gauze into the corresponding fixing part four 36 on the upper side for fixing, then continue to unfold the medical gauze to the right, put the unfolded medical gauze into the fixing part three 32 for fixing, continue to unfold the medical gauze downwards, put the unfolded medical gauze between the fixed block one 223 and the fixed block two 225, manually rotate the handle one 234 to make the fixed block two 225 move towards the fixed block one 223 to clamp and fix the medical gauze, continue to unfold the medical gauze to the right, put the unfolded medical gauze between the fixed block three 263 and the fixed block four 265 on the right side, rotate the handle two 274 to fix the medical gauze, continue to unfold the medical gauze roll upwards, put the unfolded medical gauze roll into the corresponding fixing part four 36 on the upper side for fixing. If the number of the first movable brackets 24 required is more than two, then during the whole process, there is no need to gradually fix the parts of the medical gauze between the fixed block one 223 and the fixed block two 225, between the fixed block three 263 and the fixed block four 265, and inside the fixed block three 263 and the fixed block four 265. When the medical gauze has completed all the paths, manually rotate the leftmost handle two 274, thereby driving the rotating rod two 273 to rotate. Under the drive of the belt one 285, the lower pressing wheel one 237, the lower pressing wheel two 277, the moving wheel 284 and the rotating wheel two 275 rotate synchronously, making the fixed block two 225 move towards the fixed block one 223 and the fixed block four 265 move towards the fixed block three 263 to fix the part of the medical gauze on the lower side. At the same time, adjust the fixing part four 36, and with the cooperation of the transmission part two 38, fix the part of the medical gauze on the upper side. During the whole process, the operator can adjust the medical gauze to make the medical gauze 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 command 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 the medical gauze are broken. After recording all the data, calculate the mean and compare it with the standard data to determine whether the tensile strength of the medical gauze meets the standard.
