Method and device for judging position of catheter, and monitoring equipment

Abstract

The invention discloses a method and device for judging the position of a catheter, and monitoring equipment. The method comprises the following steps that a plurality of physiological parameter dataof a patient are acquired; a plurality of parameter characteristic signals are generated according to the physiological parameter data; the parameter characteristic signals are matched with a pre-established position signal template; when the matching result meets the preset condition, the position of a human body structure corresponding to the parameter characteristic signals is determined; and the current position of the catheter is determined according to the position of the human body structure. Therefore, in the whole process, while physiological parameters are monitored, the position determination of the catheter can be completed synchronously, no additional auxiliary equipment is needed, the operation space during operation is saved, and the problems of the space constraint of medical staff in medical treatment of the patient due to various equipment, and the hidden danger of treatment due to inconvenient operation are solved.

Description

technical field [0001] The invention relates to the technical field of medical monitoring, in particular to a method, device and monitoring equipment for judging the position of a catheter. Background technique [0002] In clinical practice, in many cases, it is necessary to intubate a patient's blood vessel or cavity. For example, arterial and venous blood pressure monitoring, cardiac output monitoring, arterial blood pumping, supraluminal rehydration, PICC (Peripherally Inserted Central Venous Catheters, central venous catheters via peripheral venous puncture) drug administration, etc. At present, when intubation is performed clinically, the current position of the intubation often requires subjective judgment by medical staff based on years of clinical experience, and since the current specific position of the intubation cannot be known, strong operational proficiency is required. In addition, because the organizational structure of patients is different, the position of...

Problems solved by technology

However, this method often requires the tacit cooperation of at least two doctors, or the intubation medical staff will intubate with one hand and perform the main auxiliary guidance with the other hand, or the auxiliary doctor will perform the main guidance. However, this requires the auxiliary doctor to guide the catheter The current position has an accurate judgment and quick response ability

At the same time, in order to obtain a better imaging and positioning effect, it is often necessary to place ultrasound and X imaging equipment closely around the operation position of the intubation, which will inevitably hinder the operator's operation, which is very inconvenient and even hinders the operator's insertion. tube operation
