Description
Technical Field
The invention relates to the technical field of a gas partial pressure monitoring catheter, in particular to an anti-blocking type nasopharynx sampling gas partial pressure monitoring catheter.
Background
The monitoring of the partial pressure of gas is an important link for monitoring the respiratory function, the gas inhaled and exhaled by a patient is extracted through the gas sampling conduit, and the respiratory function condition of the patient can be effectively judged by monitoring the components and the partial pressure parameters of the gas. Particularly in clinical anesthesia, the monitoring technology has very important significance for the respiratory function management of patients. The medical gas monitor mainly adopts three gas detection technologies of electrochemistry, infrared ray and paramagnetic property. According to the gas sampling position of the gas partial pressure monitoring sensor, the method can be divided into a main flow type acquisition method, a bypass flow type acquisition method and a shutoff type acquisition method, and a bypass flow acquisition technology is generally adopted clinically. Limited by the gas sampling condition, the tip of the gas sampling tube needs to be connected to a specific position of the closed artificial airway (the junction of the ventilation catheter and the ventilation loop), so that the air can be prevented from being mixed during gas sampling, and the gas actually ventilated by the patient can be extracted. The technique is therefore generally limited to general anesthesia patients with tight artificial airway ventilation.
Currently, gas monitoring technology is widely applied to general anesthesia patients with tight artificial airway ventilation, but for spontaneous respiration patients with non-tight artificial airway, the technology still has wider clinical requirements, especially for patients with non-tight artificial airway anesthesia. If the tip of the gas sampling tube is in the same position, the surrounding air may be mixed in during sampling, resulting in a failure of monitoring. Clinical tests prove that when the tip of the gas sampling tube is placed at the nasopharynx part of a patient, the gas sampling analysis result can be close to the sampling effect of the state of a tightly closed airway, but the common catheter or the gas sampling tube with the tip containing a positive hole structure and a side hole structure is easy to be blocked by pharyngeal secretions, so that the monitoring fails.
