Anesthesia catheter

Abstract

The invention discloses an anesthesia catheter, and particularly discloses a suction anesthesia catheter capable of retaining spontaneous respiration of a patient. The anesthesia catheter comprises a nasal cavity insertion end and a device connection end, and an anesthesia catheter body is provided with an air inlet catheter, a negative pressure suction catheter, an end-expiratory gas concentration monitor connecting catheter, an air bag and an air bag catheter. When respiration anesthesia is carried out by means of the anesthesia catheter, the anesthesia catheter has the advantages that spontaneous respiration of the patient can be retained, and the upper airway is kept from impeding; the anesthesia catheter cannot occupy the mouth cavity, the brain and other surgical spots; the anesthesia catheter does not pass the glottis, so that the patient conveniently pronounces, and leakage of inhalation anesthetics cannot be caused; the concentration of end-expiratory CO2 and anesthesia gas can be conveniently and accurately monitored.

Description

technical field [0001] The invention belongs to the technical field of medical equipment and relates to an anesthesia catheter, in particular to an inhalation anesthesia catheter capable of retaining spontaneous breathing. Background technique [0002] Inhaled anesthetics enter the body and are eliminated through pulmonary ventilation, and the adjustment of the depth of anesthesia is easier than other intravenous anesthetics. Inhalation of anesthetics such as sevoflurane has good analgesic and anesthetic effects, and has light respiratory depression, and can complete body surface and limb operations while retaining spontaneous breathing, such as prostate resection, hysterectomy, etc. ; When assisting spinal anesthesia and nerve block, it can complete laparoscopic cholecystectomy, intestinal tumor resection, etc. anesthesia. [0003] The commonly used inhalational anesthesia tools mainly include face mask, laryngeal mask and endotracheal intubation. When performing wake-up ...

AI Technical Summary

Problems solved by technology

When performing wake-up anesthesia for craniocerebral surgery, using a face mask to perform inhalation anesthesia will cause upper airway obstruction due to the tongue falling behind, while using a laryngeal mask or endotracheal intubation will occupy the patient's glottis and make it impossible to speak, and it is impossible for the patient to be able to speak during the operation. The requirement to talk to the surgeon; in addition, when performing minor oral surgery, if a mask or laryngeal mask is used for inhalational anesthesia, the surgical site will be occupied, and if a tracheal intubation is used, muscle relaxants will be used, which will prevent the patient from breathing spontaneously; At present, the airway tool for nasal non-tracheal intubation is only the nasopharyngeal airway, but if the nasopharyngeal airway is directly used for inhalation anesthesia, the patient's mouth and nose will not be closed, causing the patient's exhaled anesthetic gas to leak through the mouth and nose. Operating room, causing pollution, and it is impossible to monitor the end-tidal CO conveniently and accurately 2 and the concentration of anesthetic gas
