Abstract

The invention discloses a spinal puncture teaching model, belonging to the field of medical teaching. The spinal puncture teaching model comprises a spinal puncture model, a puncture needle, a cerebrospinal fluid flow guide device, an operation control circuit and a flexible drainage pipe, wherein the spinal puncture model consists of a lumbar vertebrae bone, a sacral vertebrae bone and a round pipe; a pressure sensor is arranged in the round pipe; a needle handle is provided with a side through pipe and a straight through pipe; the cerebrospinal fluid flow guide device consists of a liquid storage tank, a liquid feeding port, a liquid discharging port, cerebrospinal-fluid drainage liquid, a micropump, a micropump power supply circuit and a hydrops depth control floater; the operation control circuit consists of a power supply, a position indicating circuit and a hydrops depth control floater; and the position indicating circuit consists of a pressure sensor, an in-place indicating lamp and a relay. The spinal puncture teaching model disclosed by the invention has the beneficial effects that the effects of convenience, durability and intuition can be achieved, the notification of the operation practice working and the finishing condition information of spinal puncture can be directly realized, the repeated use can be achieved, and the purpose that the spinal puncture teaching model can bear the practice of repeated operation and training is realized.

Description

technical field [0001] The invention relates to a spinal cord puncture teaching model, which belongs to the field of medical teaching. Background technique [0002] Since the extraction of cerebrospinal fluid is a common method of spinal cord puncture at present, it mainly refers to the puncture of the waist from the hip to the upper end of the thigh, and the "spinal fluid" can be extracted from it after the puncture. Learning the operation of spinal cord puncture is a basic clinical skill. The previous practice can only be performed at the clinical operation site in the hospital, and the teacher will operate and explain to the students, and the students cannot directly perform the operation. The simulation model operation that has emerged in recent years can effectively assist students in spinal cord puncture exercises. However, most of the current spinal cord puncture models put self-made spinal fluid in the simulated spinal cord canal. When practicing the puncture operat...
