Problems solved by technology

[0004] Although the pH electrode catheter adopts integrated assembly to solve the problem of water leakage, it still has the following problems: in order to prevent the insulated wire from falling off, the insulated wire needs to be wound on the catheter, and the impedance ring needs to be closed and positioned through the necking process , the process is complicated, the efficiency is low, and it cannot meet the requirements for the high production capacity of the impedance-pH electrode catheter

Embodiment 1

[0038] Such as figure 1 The impedance-pH electrode catheter shown includes a catheter body 3 with an antimony electrode 1 and an impedance component 2 on the side, a reference electrode 4 is arranged at the front end of the catheter body 3, and a connection module is arranged at the rear end of the catheter body 3 5. The first insulated wire 6, the second 7 insulated wire 7 and the third 8 insulated wire whose rear end is connected to the connection module 5 are perforated in the conduit body 3, wherein the first 6 insulated wire, the second 7 insulated wire 7 and the third 8 insulated wire are all enameled wire, and the front end of the insulated wire 6 is connected to the reference electrode 4, and the front end of the insulated wire 2 7 is connected to the antimony electrode 1.

[0039] Such as image 3As shown, there is an annular positioning groove 9 recessed radially along the catheter body 3 on the side of the catheter body 3. The impedance component 2 is closed and an...

Embodiment 2

[0054] The structural principle of this embodiment is basically the same as the structural principle of Embodiment 1, the difference is that the mold 11 is set in a cylindrical or elliptical shape as a whole, and when heating in step 5, the mold 11 is put into a reflow furnace as a whole for heating .

Embodiment 3

[0056] The structural principle of this embodiment is basically the same as that of the first embodiment, except that the raw material is a tin-bismuth alloy solder paste with a tin content of 42%, a bismuth content of 58%, and a heating temperature of 138°C.

Abstract

The invention provides an impedance-pH electrode catheter and a processing method thereof, which belong to the technical field of medical instruments. The problems that an existing impedance-pH electrode catheter is unreliable in quality and complex in machining procedure are solved. The impedance-pH electrode catheter comprises a catheter body provided with an antimony electrode and an impedancecomponent arranged at the side part; a reference electrode is arranged at the front end of the catheter body; a connecting module is arranged at the rear end of the catheter body; an insulated wire I,an insulated wire II and an insulated wire III are arranged in the catheter body in a penetrating manner; an annular positioning groove is formed in the side portion of the catheter body, the impedance component is annular and positioned in the positioning groove, a through hole communicated with an inner cavity of the catheter body is formed in the bottom of the positioning groove, the front endof the insulated wire III penetrates out of the through hole and then is connected with the impedance component, raw materials are poured into the positioning groove in the machining process, and theimpedance component is formed in a heating curing mode. The electrode catheter has the advantages of reliable quality, high processing efficiency and the like.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and relates to an impedance-pH electrode catheter and a processing method thereof. Background technique [0002] With the development of medical devices, the demand for impedance-pH electrode catheters for esophageal pH monitoring (gastroesophageal reflux disease) is increasing day by day, and the demand for the production capacity of impedance-pH electrode catheters is relatively large. The current pH catheter is a cylinder, which is assembled piece by piece. The insulated wire needs to pass through the impedance ring and then be bent and welded to the impedance ring. The welding efficiency is low and the cost is high. At the same time, the insulated wire is easy to bend after bending. Rubbing against the impedance ring port, there is a risk of disconnection; the insulated wire needs to pass through the center of multiple cylindrical parts such as the front end impedance ring, catheter, ...
