Description

Breathing nasal tube device

The present invention relates to a medical respiratory device, and more particularly to a respiratory nasal canal device.

The respiratory nasal tube device is one of the devices for treating respiratory symptoms. In order to increase the oxygen content or water content of the patient during inhalation, a respiratory nasal canal device is usually inserted into the nasal cavity of the patient, and the nasal cannula is inserted through the respiratory nasal cannula. The device delivers a high oxygen content or high water content medical gas to the patient's respiratory tract.

The traditional respiratory nasal tube device mainly comprises a body, a two-nose tube extending from the body and a wearing member mounted on the body, the body is used for connecting the gas pipe, the nose tube is for inserting the nasal cavity of the patient, and the wearing part is for providing The patient wears the head, and finally the medical gas enters the patient's nasal cavity sequentially through the gas pipe, the body and the nasal tube.

However, the above-mentioned respiratory nasal tube device has the following disadvantages. Because the nasal connecting tube has a small caliber and a thin tube wall, the nasal connecting tube is easily bent and deformed when pressed, and the position where the nasal connecting tube is bent is farther away from the body, and the more deformed space is closed. The mouth of the tube causes the patient's condition to deteriorate or be harmed. Therefore, how to prevent the occurrence of closed nozzles when the nose is under pressure is the focus of the research and development of the system.

In view of this, the creator has made great efforts to solve the above problems by focusing on the above-mentioned prior art, and has devoted himself to the application of the theory, that is, the goal of the creator's improvement.

The present invention provides a respiratory nasal canal device, which is characterized in that when the nasal connecting tube is compressed, the pressure is concentrated on the concave ring segment, so that the other portions of the nasal connecting tube are not easily deformed, so that the respiratory nasal canal device has the advantages of smooth air supply.

In the present embodiment, the present invention provides a respiratory nasal canal device comprising: a nasal cannula body having a cavity inside and an externally extending two-nose tube connecting the cavity, the nasal cannula body and each A junction ring portion is formed at the junction of the nasal connector, and at least one of the nasal tube body and each of the nasal connectors has a concave ring segment recessed on one side of each of the interface ring portions, the thickness of the concave ring segment being smaller than the The thickness of the nasal cannula body, the thickness of each of the nasal adapters, and the thickness of each of the overlapping ring portions.

Based on the above, when the nasal connecting tube is compressed, the thickness of the concave ring segment is the thinnest, so the pressure at other places of the nasal connecting tube will be dispersed, so that the pressure is concentrated on the concave ring segment, and the other portions of the nasal connecting tube are not easily deformed, and only the depressed ring segment will be bent. Deformation, and because the position of the concave ring segment is closer to the intersection ring portion, the deformation of the concave ring segment will be pinched by the junction ring portion and cannot be excessively bent, thereby avoiding the situation in which the concave ring segment is bent and closed. Reaching the nasal cannula device has the advantage of smooth air supply.
