Self-hard tube of oxygen for medicine

Abstract

Disclosed is a self-fixed medical oxygen tube, including an oxygen-inlet tube and a gas-outlet tube which are connected with a nasal plug. The invention is characterized in that the shape of the nasal plug is similar to the shape of a nostril, with a nose-clip is arranged at the root of the nasal plug. A unilateral valve is arranged respectively at the connecting place of the nasal plug and the oxygen-inlet tube and the connecting place of the nasal plug and the gas-outlet tube. The size of the nasal plug is determined by the requirement of the human body, with a plurality of specifications left for choice. The nose-clip plays a role in fixing the nasal plug to ensure that the nasal plug does not easily fall off. As the nasal plug can be formed in one piece by adopting the innocuous, peculiar-small-free material that has certain elasticity, the elasticity of the material can be used to make the plugging-in and taking-off easy, so that the pain of the patient is relieved. In order that the plug can fill the nasal cavity as best as possible and in order to prevent the gas from flowing out, sponge and other flexible material can be laid on the surface of the nasal plug. The invention, which changes the mode of nasal plug fixing by the adhesive plaster, provides a self-fixed medical oxygen tube which is of reasonable structure, low cost, convenient usage and good effect.

Description

technical field [0001] The invention relates to a medical appliance, in particular to a self-fixing medical oxygen suction tube. Background technique [0002] Oxygen inhalation tubes commonly used clinically are mostly single rubber strip tubes with small holes at the end. During use, the nasal plug at the head of the oxygen inhalation tube is inserted into one nostril. Because the tube is in the shape of a long strip, the oxygen inhalation tube itself cannot be fixed, so it needs to be fixed by external force after it is inserted into the nostril. Under the existing conditions, it is usually fixed with adhesive tape, that is, after inserting the oxygen suction tube into the nostril, tear off a long strip of adhesive tape, stick the oxygen suction tube outside the nostril for a week, and then stick the two ends of the adhesive tape on the nose or The face on either side of the nose. Although this method can play a certain role in fixing, many problems are prone to occur d...

AI Technical Summary

Problems solved by technology

Although this method can play a certain role in fixing, many problems are prone to occur during use, such as the nostrils are blocked due to too large adhesive tape; too deep insertion of the tube will increase the pain of the patient and make the patient feel a foreign body sensation; If it is shallow, the oxygen suction tube is easy to fall off

More importantly, this fixation method requires the patient to maintain a certain posture all the time. Once the head moves, it is easy to cause the adhesive tape to fall off, which directly affects the medical effect

Not only that, because the bonding effect of the tape is greatly affected by the temperature, if the temperature is too high or too low, the bonding effect will be reduced accordingly, so this fixing method has relatively high requirements for room temperature and harsh service conditions
