Abstract

The invention discloses a multi-interlayer catheter sheath, and relates to the technical field of medical instruments, the catheter wall of the catheter sheath comprises an inner layer, a middle layer and an outer layer which are sequentially arranged from inside to outside; the middle layer comprises a heat conduction material layer used for conducting heat and a metal layer providing radial support for the catheter wall of the catheter sheath. The heat conduction material layer for heat conduction is additionally arranged on the middle layer of the catheter sheath, and the heat conduction material layer has the characteristic of high heat conductivity, so that the heat transfer efficiency is high, the temperature difference on the catheter sheath can be quickly reduced, and the temperature equalizing effect is achieved.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a multi-layer catheter sheath. Background technique [0002] In cryoablation, the introducer sheath is designed to introduce various cardiovascular catheters into the heart, and is a medical device that provides access to other therapeutic materials such as dilators and balloon-type cryoablation catheters. [0003] At present, the problem of introducer sheaths on the market is that the thermal conductivity of the introducer sheath is small, which leads to the use of devices with large surface temperature differences in the working channel of the introducer sheath, which may easily cause cold and heat stimulation to the human body. Contents of the invention [0004] Therefore, the technical problem to be solved by the present invention is to overcome the defects of low thermal conductivity and large surface temperature difference of the catheter sheath in the prior a...
