Description

Non-resistance puncture testing device for peripheral hemostix

Technical Field

The utility model belongs to the technical field of medical instrument inspection and detection, and particularly relates to a resistance-free puncture testing device for a peripheral blood collector, which is suitable for inspection of the peripheral blood collector.

Background

In the past decade, the product series of peripheral blood sampling devices has been divided into industries with different blood sampling requirements mainly due to the continuous development of peripheral blood testing technology, and currently, the peripheral blood sampling devices are mainly used in hospitals (independent use) and household (used together with pens). Peripheral blood is mainly used for examination items such as whole blood cell analysis, blood type, blood sugar, blood sedimentation, newborn screening and the like. With the continuous development and the increasing perfection of modernization, micro-quantification and convenience of inspection medical technology, rapid micro-quantification methods are established for some projects with large blood volume in the past, such as trace elements, infectious markers, antibodies of infectious diseases, bedside detection projects and the like. The hemostix products have rich specifications, various varieties and different structural materials, and can be roughly divided into three types:

1) hand-held type hemostix: the blood sampling device can be held by hand to independently take blood, a general blood sampling pen with a needle seat can be selected and matched to take blood, the blood sampling device can be used repeatedly, the needle tip is protected before use, and the needle tip is exposed after use and needs to be protected manually;

2) semi-automatic hemostix: the needle can not be independently used, a corresponding blood sampling pen is required to be used for sampling blood, some blood sampling pens can be repeatedly used, the needle tip is protected before use, and the needle tip automatically retracts and is automatically protected after use;

3) full-automatic hemostix: the automatic blood sampling device can automatically and independently sample blood without being matched with a blood sampling pen, and can not be reused, the needle tip is protected before use, and the needle tip automatically retracts and is automatically protected after use.

In order to ensure the use safety of the hemostix, various performances of the hemostix need to be reliably tested, wherein the resistance-free puncture depth is an important index, the blood sampling depth of the handheld hemostix is related to the proficiency of operators, the semi-automatic hemostix and the full-automatic hemostix are related to instruments, if the blood sampling depth is too deep, the pain of the person to be subjected to blood sampling is increased, and the blood sampling risk is increased; the blood sampling depth is too shallow, blood sampling failure can be caused, the generally specified maximum resistance-free puncture depth is not more than 4mm, the damage degree to the puncture wound surface is reduced as far as possible, and the safety degree is higher when the blood sampling depth is far away from the peripheral superficial vein.

In the actual test operation, if the length of the needle tip is used as the maximum puncture depth, on one hand, the clinical use state cannot be well simulated, and the length of the needle tip is possibly far greater than that in the actual use state; on the other hand, the length of the test needle point is a destructive test, the test efficiency is low, and the test is not beneficial to detection.
