Title:
DEVICE FOR CONNECTING CATHETER TO INJECTION TUBE
Document Type and Number:
WIPO Patent Application WO/1990/015578
Kind Code:
A1
Abstract:
A device for connecting a catheter to an injection tube, which is provided with an elastic tube into which an open end of the tubular catheter having electrodes disposed at the closed end thereof and also having conductive wires to be connected to said electrodes and taken out at the open end thereof and an open end of the injection tube having a mechanism for fluid injection at the other end thereof are inserted so that both open ends are connected end-to-end and the conductive wires are taken out to the side of the injection tube; and a sealing agent to cover respective surfaces of the catheter, injection tube, and elastic tube which are coated with an adhesive. The catheter, injection tube, and elastic tube, when coated with an adhesive of high viscosity, are compatible with the hard sealing agent lying thereabove and a small case composed of two pieces of members and enclosing the sealing agent increases the strength of the device, whereby the device is prevented from being deformed and causing leakage of fluid through the gap even when subjected to external force, that is, is improved in resistance to external pressure. In addition, connection of the conductive wires between the electrodes and the terminals arranged on the side of the small case serves to tightly fix the wires in the sealing agent packed in the case and causes no breakage of the wire, whereby the wires are connected to the external parts through the terminals to improve the reliability of the device.
