Sole blood sampling exercise model

By adding a detachable local blood collection patch and a compartmentalized cavity design to the foot model, the correct needle insertion location and the foot congestion process can be simulated, solving the problem that existing models cannot determine the needle insertion location, improving teaching effectiveness and realism, and reducing costs.

AI Technical Summary

Technical Problem

Existing foot prick blood sampling training models cannot determine whether the needle insertion location is accurate, and can only simulate the blood flow of newborns through foot massage, resulting in poor teaching effectiveness.

Method used

Two detachable local blood collection patches are added to the foot model. Each local blood collection patch is divided into a first congestion chamber and a second congestion chamber by a separator. The trainee simulates foot congestion by pushing the fluid in the second congestion chamber to the first congestion chamber. The fluid only flows out when the needle is inserted in the correct position. Combined with the simulated foot massage congestion patch, the actual blood collection process is simulated.

Benefits of technology

It improves the accuracy of needle placement and teaching effectiveness, has a high degree of realism, reduces the frequency of changing local blood collection patches, and lowers teaching costs.

Abstract

The utility model provides a plantar blood sampling practice model, and belongs to the technical research field of teaching models. In order to solve the problems that an existing plantar blood sampling exercise model cannot judge whether the acupuncture position is accurate or not and blood flow of a newborn can only be simulated in a plantar massage mode, two detachably connected local blood sampling pieces are additionally arranged on a plantar model; a containing cavity in each local blood sampling piece is divided into a first hyperemia cavity and a second hyperemia cavity through a partition piece; during use, the side, provided with the first hyperemia cavity, of the local blood sampling piece is located on the side edge of the sole, and the side, provided with the second hyperemia cavity, of the local blood sampling piece is located on the foot side. A practicer squeezes fluid in the second hyperemia cavity into the first hyperemia cavity to simulate sole hyperemia, so that when a learner punctures a needle on the outer side edge or the inner side edge of the sole, the fluid in the local blood sampling piece flows out, if the puncturing position is incorrect, no fluid flows out, the reality degree is high, and the teaching effect is good.
