Problems solved by technology

This method is only suitable for double-lumen catheters with large double-lumen openings, and is not suitable for the double-lumen urethral pressure measuring tube used in urodynamic analyzers
[0006] 3) Insert two small catheters into the double-lumen tube in advance, then design a branch mold, and inject the connected double-lumen tube as a part into the branch on the injection molding machine. This method has high requirements on the material of the double-lumen tube , high temperature resistance, high stability, not suitable for existing conduits

Abstract

The invention discloses a double-cavity urethra piezometer tube connecting device which comprises a splitter (1), a single-cavity pipe A (2), a single-cavity pipe B (3), a double-cavity pipe (4) and a plug (5). A primary runner (6) and two secondary runners both communicated with the primary runner (6) are arranged inside the splitter (1), the double-cavity pipe (4) is arranged in the primary runner (6), the side wall of a cavity A (9), close to the secondary runner B (8), of two cavities in the double-cavity pipe (4) is provided with a side hole (10) communicated with the secondary runner B (8), and the plug (5) is arranged in the cavity A (9). The invention further discloses a double-cavity urethra piezometer tube connecting method. According to the double-cavity urethra piezometer tube connecting device and method, the technical method that the side hole and the plug are arranged in the double-cavity pipe is adopted, defects existing in existing connecting methods are ingeniously avoided, and the double-cavity urethra piezometer tube connecting device is simple in process, convenient to manufacture, high in finished product yield, and high in production efficiency and practicality; in addition, the double-cavity urethra piezometer tube connecting device is simple in structure, reliable in product performance and capable of fully meeting clinical application requirements.

Description

technical field [0001] The invention relates to a medical double-cavity urethral pressure measuring tube, in particular to a connecting device and a connecting method for a double-cavity urethral pressure measuring tube. Background technique [0002] Urodynamics is a subdiscipline of urology. Carrying out urodynamic research is not only of great practical value for clinical diagnosis and treatment of voiding dysfunction diseases, but also of great scientific value for voiding physiology, neurourology, gynecological urology and related pharmacology research. At present, the indicators directly measured by routine urodynamics are internal pressure of the bladder, urethra, and rectum, urinary flow rate, and urine output. The most commonly used method is the invasive urodynamic examination method: inserting a pressure measuring tube to directly measure the pressure change in the bladder, and at the same time measure the urine flow rate; pull the pressure measuring tube with con...
