Abstract

The invention relates to the field of medical auxiliary instruments, in particular to a nasal catheter. The nasal catheter comprises a connector, a fluid exchange tube, at least one nasal tube and a sealing assembly, wherein the connector is used for being connected with a fluid supply end; the fluid exchange tube which is connected with the connector and of which the interior provided with a cavity capable of holding fluid; the at least one nasal tube is arranged on the fluid exchange tube and is used for going deep into a nasal cavity; and the sealing assembly is arranged on the outer wall of the nasal tube and can control a blocking state. The nasal catheter has the advantages of being simple in structure, easy to operate, low in production cost and more convenient and practical, increases the convenience of painless gastroscope operation, reduces the workload of a medical worker, and greatly reduces the risk of endangering the life safety of a patient.

Description

technical field [0001] The invention relates to the field of medical auxiliary equipment, in particular to a nasal catheter. Background technique [0002] Clinically painless gastroscopy requires anesthesiologists to inject intravenous anesthetics to patients, but because intravenous anesthetics have strong sedative and respiratory depression effects, respiratory depression will cause hypoxia in the human body, and severe hypoxia in the human body is likely to be life-threatening. Therefore, clinically Use nasal cannula to inhale oxygen to solve the patient's hypoxia problem, and confirm whether the patient's lung function is normal by monitoring the patient's finger pulse oxygen. Usually, it is necessary to control the index of finger pulse oxygen between 97% and 100%. In the case of this indicator, the patient needs to use a mask to inhale oxygen to relieve the patient's hypoxia. However, because the gastroscope needs to enter from the mouth, if the mask is inhaled oxygen,...
