Embodiment Construction

[0019] The present invention will be further described below in conjunction with the drawings and embodiments:

[0020] figure 1 The nasal passage diameter detection tube includes a detection tube body 1 with a length indicator 9 on the outside. A guide part with a small front and a large back is provided in the front part of the detection tube body 1. The length of the guide part is 1 cm, and the side wall of the guide part There are two through holes 3 with asymmetric upper and lower positions; a measuring airbag 2 is provided on the outer circumference of the detecting tube 1, and the distance from the outlet 8 of the detecting tube 1 to the measuring airbag 2 is 2 cm; the measuring airbag 2 passes through the attachment The inflation tube 4 on the inner wall of the detection tube body 1 is connected to the indicating airbag 5 containing the one-way valve 6. Since the indicating airbag 5 is connected to the measuring airbag 2, it can be directly seen from the indicating airba...

Abstract

The invention discloses a nasal cavity channel diameter detection tube and relates to the field of medical consumables. The detection tube is provided with a detection tube body, wherein the front end of the detection tube body is provided with a guide part which is small in front and big in back, and the outer side of the detection tube body is provided with a length mark; the upper portion and the lower portion of the tube wall of the guide part are provided with through holes, a measuring air bag is arranged outside the portion, behind the guide part, of the detection tube body and connected with an inflator through an inflatable pipe via a one-way valve, and the inflator is provided with a scale which corresponds to the diameter of the measuring air bag and reflects the air injection amount; the detection tube body is connected with a breathing machine or an aspirator through an inlet and can provide an oxygen supply channel or suck secreta in the nasal cavity. The detection tube can achieve measurement of the passing diameter of the nasal cavity channel to provide a basis for choosing a proper cannula or catheter for a nasal trachea cannula and avoid aspiration by mistake caused by nasal mucosa damage and bleeding when an improper cannula or catheter is adopted.

Description

technical field [0001] The invention relates to the field of medical consumables, in particular to a detection tube for detecting the inner diameter of a nasal passage. Background technique [0002] Endotracheal tube is an indispensable medical device for clinical tracheal intubation. It is an important measure in the rescue of patients with cardiopulmonary cerebral resuscitation and respiratory dysfunction. It is a safety measure in the anesthesia process and is widely used in many medical fields such as first aid and surgery. Clinically, the use of tracheal tubes is normally to insert the tracheal tube from the patient's mouth into the trachea to assist breathing through auxiliary equipment, but clinically due to the surgical needs of the patient's maxillofacial and oral cavity or the patient's congenital or acquired When general anesthesia is required for mouth opening difficulty caused by sexual reasons or ankylosing spondylitis, nasal cavity and tracheal intubation mus...
