What is the test principle of suture connection force tester YY1116-2020?

Suture connection force tester YY1116-2020 medical suture has separate sutures and medical sutures with needles, and suture connection force refers to sutures with needles
.
The detection of suture connection force with needle requires the use of suture connection force tester, today Weixia Technology will briefly introduce you to the suture connection force tester
.
Suture connection force tester is an efficient testing equipment for national inspection of the performance of manufacturers' products, mainly used to determine the physical characteristics of medical suture needle connection strength, is one of
the important means to identify sutures with needles.
The suture connection force tester is designed and manufactured according to the relevant standards of YY1116-2020 absorbable surgical sutures, which fully meets the relevant standards of the national pharmaceutical industry in terms of technical performance and technical indicators, and is specially used for the measurement
of medical suture connection force.
In the YY116 - 2020 Standard for Absorbable Surgical Sutures, there are provisions on the connection force of needle sutures, which require that the average and individual values of needle and thread connection strength should meet the requirements
of Table 4.
Experimental step 1 of needle and thread connection strength, the needle and suture are fixed on the two fixed fixtures of the material testing machine respectively, so that the connection between the suture and the needle is tight, and the needle tail is coaxial with the suture, and the connection of the needle and thread is pulled off according to the specified speed, and the maximum tensile force value is recorded as a single value
of the strong needle and thread connection.
2.
Repeat the above steps to complete the test and test
.
3.
Calculate the average value of all individual values as the strength average of
the needle and thread connection.
The suture connection force with needle is only qualified if the suture meets the standard requirements, and the test results of the suture connection force tester are an important basis for
judging the quality of the suture.
The above is a brief introduction of the suture connection force tester, originally provided by Weixia Technology, I hope it will help
you.
