Problems solved by technology

However, most of the current puncture models are made by putting self-made liquid into the simulation model. When practicing the puncture operation, ordinary puncture needles are used for puncture practice. Due to the limitation of the production technology and materials of the simulation model, after a few times the puncture liquid will Leakage, making it impossible to continue the operation training of piercing

Abstract

The invention discloses a puncture needle for teaching, which belongs to the technical field of medical teaching aids and comprises a needle tip, a needle rod, a needle handle and a direct through pipe. The needle tip is located at one end of the needle rod, the other end of the needle rod is connected with the direct through pipe through the needle handle, an electric switch circuit formed by series connection of a spring plunger switch, a power supply and a simulation indicating lamp is arranged in the needle rod, and the spring plunger switch is arranged on one side of a combining position of the needle tip and the needle rod. The puncture needle for the teaching is convenient, durable and visual, can directly achieve puncture operation practice work and complete situation information, and can be used repeatedly.

Description

technical field [0001] The invention relates to a puncture needle for teaching and belongs to the technical field of medical teaching appliances. Background technique [0002] The operation of puncture is a basic clinical skill. The previous practice can only be performed at the clinical operation site in the hospital. The teacher will operate and explain to the students, and the students cannot directly perform the operation. In order to increase students' clinical operation skills, the simulation model operation that has emerged in recent years can effectively assist students in puncture exercises. However, most of the current puncture models are made by putting self-made liquid into the simulation model. When practicing the puncture operation, ordinary puncture needles are used for puncture practice. Due to the limitation of the production technology and materials of the simulation model, the liquid will be punctured after a few times. Leakage, so that the operation trai...
