Disposable oral-nasal oxygen tube

Abstract

The invention discloses a disposable oral-nasal oxygen tube, which comprises a long catheter. An oxygen source joint is arranged at one end of the long catheter. Two short catheters are connected with the other end of the long catheter through a T joint, respectively. A nasal frame structure with an inner cavity is connected between the two short catheters. Nose plugs are connected to the nasal frame structure. The disposable oral-nasal oxygen tube is characterized in that: an oral inhaling tube is also connected to the nasal frame structure; the oral inhaling tube is provided with an inhaling hole communicated with the inner cavity of the frame nose structure and a positioning hole side by side with the inhaling hole; the end of the positioning hole connected with the frame nose structure is a closed end; and a flexible positioning part is clamped in the positioning hole. According to the disposable oral-nasal oxygen tube with a simple structure, oxygen is orally and nasally supplied at the same time, and using comfort is ensured; and by the flexible positioning part, a distance between an outlet of the oral inhaling tube and the nose plugs and the angle of the oral inhaling tube can be randomly changed, so that the disposable oral-nasal oxygen tube is applied to various groups.

Description

technical field [0001] The invention relates to a medical auxiliary device, in particular to a device for assisting oxygen inhalation, especially a disposable oxygen inhalation tube. Background technique [0002] In medical treatment, oxygen inhalation therapy is an important means of treatment. By inhaling oxygen, the oxygen concentration in the patient's inhaled gas is higher than the atmospheric oxygen concentration, which can increase the partial pressure of oxygen in the alveoli and improve the symptoms of hypoxia. Patients with different diseases have different needs for oxygen. For patients with respiratory diseases, quantitative oxygen inhalation every day can clean the respiratory system and relieve the condition. Patients with heart disease, stroke and other diseases can also reduce the frequency of attacks by regular oxygen inhalation , to improve visceral function, and the patient also needs to inhale oxygen during the operation.

Problems solved by technology

However, for people with nasal diseases, or people who open their mouths to breathe due to various reasons, the use of nasal oxygen tube is not effective because of poor nasal ventilation function.

[0004] Although the mask-type oxygen inhalation device can be applied to patients who open their mouths to breathe, the mask is not comfortable to use, and the cost of the mask is high. If it is made into a disposable device, the medical cost will be increased, and repeated use will affect hygiene.
