Disposal sterilized humidifying oxygen uptake pipe

Abstract

The invention discloses a disposable asepsis humidifying oxygen tube, comprising a humidifying bag (1), an oxygen inserting tube (2) and an oxygen tube (4) connected with the humidifying bag (1); the lower end of the oxygen inserting tube (2) is connected with the top part of the humidifying bag (1); the humidifying bag (1) is internally provided with a left oxygen passage (6), a right oxygen passage (7), an upper oxygen passage (8) and a lower oxygen passage (9); the two ends of the left oxygen passage (6) are respectively communicated with the oxygen inserting tube (2) and the lower oxygen passage (9); the two ends of the right oxygen passage (7) are respectively communicated with the upper oxygen passage (8) and the oxygen tube (4); the lower oxygen passage (9) is communicated with a humidifying fluid chamber (10); and a dismountable sealing mechanism which can inhibit humidifying fluid (23) from entering the right oxygen passage (7) is arranged between the upper oxygen passage (8)and the humidifying fluid chamber (10). The humidifying fluid in the humidifying fluid chamber can not enter the right oxygen passage before using the invention, thus avoiding the patient from choking during oxygen hyperventilation.

Description

Technical field: [0001] The invention relates to a medical oxygen delivery device, in particular to a disposable aseptic humidification oxygen inhalation tube. Background technique: [0002] The applicant applied for a disposable aseptic humidification oxygen suction tube on December 30, 2008, which includes a humidification bag, an oxygen inlet tube and an oxygen suction tube connected with a nasal suction head; the oxygen inlet tube The upper end of the upper end is provided with a joint for connecting with an oxygen source; the lower end of the oxygen inlet pipe is connected to the top of the humidification bag; the oxygen suction pipe is connected to the bottom of the humidification bag; the left oxygen channel, the right oxygen channel, a plurality of upper oxygen channels and a plurality of lower oxygen channels; the upper end of the left oxygen channel communicates with the oxygen inlet pipe, and the lower end communicates with the lower oxygen channel; the upper end ...

AI Technical Summary

Problems solved by technology

However, the above-mentioned disposable aseptic humidification oxygen suction tube still has a disadvantage in practical application: since the upper oxygen channel is always connected with the humidification liquid chamber on the humidification bag, before use, when once When the disposable sterile humidifying oxygen inhalation tube is tilted by external force, the humidifying liquid in the humidifying liquid chamber may enter the right oxygen channel through the upper oxygen channel. Before use, there are drops of humidification fluid in the right oxygen channel, and the drops of humidification fluid in the right oxygen channel are very likely to enter the patient's nose with oxygen when the disposable sterile humidification oxygen tube is used. choking patient

[0003] In addition, during use, since the oxygen inhalation tube connected to the humidification bag is relatively long, the oxygen inhalation tube is prone to be folded. It cannot flow to the patient's nose, so the humidified oxygen will accumulate in the humidification liquid chamber. Due to the limited space in the humidification liquid chamber, the accumulated oxygen will become more and more. Therefore, the humidification bag is very easy to cause Oxygen pressure in the humidification liquid chamber is too high and the explosion phenomenon occurs

In addition, when the above-mentioned disposable aseptic humidification and oxygen suction tube is suspended, the bacteria from the outside can easily enter the humidification liquid cavity of the humidification bag through the nasal suction head and the oxygen suction tube to pollute the humidification liquid. There is a high risk of bacterial infection while using
