Venous pressure measuring probe as well as mounting method and use method thereof

Abstract

The invention discloses a venous pressure measuring probe as well as a mounting method and a use method thereof. The venous pressure measuring probe comprises a flexible liner, a rigid shell and a stress transfer medium, wherein the liner is filled with the stress transfer medium; the liner is mounted on the shell; the liner comprises a bracket, an optical fiber pressure sensor, an optical fiber lead and a cylindrical film cylinder; the film cylinder is sleeved on the bracket; a sealing cavity is formed by the film cylinder and the bracket; the optical fiber pressure sensor is in optical hot-melting connection with the optical fiber lead; the optical fiber pressure sensor is accommodated in the sealing cavity; and the optical fiber lead passes through the liner and extends out of the bracket. The venous pressure measuring probe has the advantages that the venous pressure measuring probe is small in size, so that a pressure measuring operation can be performed by inserting the venous pressure measuring probe into a detected part in human body by virtue of a medical endoscope and a biopsy tool channel; the venous pressure measuring probe can serve as a key part of a non-invasive venous pressure measuring device; and the venous pressure measuring probe is suitable for an effective non-invasive detecting device for measuring venous pressure in human body.

Description

technical field [0001] The invention relates to the field of fluid pressure detection, in particular to a venous blood pressure measuring probe suitable for medical clinical application. Background technique [0002] In modern medical clinic, monitoring the venous blood pressure of the human body is an important testing technique. The commonly used inspection technique is the pioneering introduction of pressure measurement. There are two main methods of this pressure measurement. One is to insert the introduction catheter of the pressure measurement device into the venous blood vessel through minimally invasive surgery. The average blood pressure is calculated by comparing the water pressure of the tube with water; another way is to directly measure the blood pressure by inserting the miniature pressure sensor that has appeared in recent years into the venous blood vessel through puncture. [0003] The common defect of the above methods is that the pressure measurement oper...

AI Technical Summary

Problems solved by technology

[0003] The common defect of the above methods is that the pressure measurement operation must destroy the venous blood vessel wall and cause trauma. Although it will not cause serious consequences under normal circumstances, it is a pioneering venous blood pressure measurement for interventions in internal organs and viscera of the human body, especially for venous blood pressure. When the blood pressure is high and varicose veins have already appeared locally, pioneering measurement may cause the wound to fail to heal itself and cause massive bleeding, which is usually a taboo item in clinical application
