本考案は、種々の呼吸疾患患者の呼吸補助に用

めのアダプターに関するものである。[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an adapter for connecting different types of breathing circuits used for respiratory assistance for patients with various respiratory diseases.
酸素などのガスを患者に吸入させる方法には、
大別して密閉式と開放式がある。密閉式は麻酔等

Methods of inhaling gases such as oxygen to patients include
There are two main types: closed type and open type. The closed type is a method used for anesthesia, etc., in which a tube is inserted into the trachea, and oxygenated breathing gas is forcibly delivered from the outside to the lungs under positive pressure.
一方、開放式は慢性呼吸疾患患者が長期間にわ

両側に接続した、一般に鼻カニユーラと呼ばれる
呼吸回路が用いられている。 On the other hand, in the open type, patients with chronic respiratory diseases inhale by inserting the tip of the oxygen supply tube into their nostrils over a long period of time, and most of them use the oxygen supply tube 11 as shown in Figure 3. A breathing circuit generally called a nasal cannula is used, which is bifurcated and one tube end 12 is connected to both sides of a nasal cannula part 13 having a pair of nostril insertion tubes 14 inserted into the left and right nostrils. .
気管内にチユーブを挿入（以下、気管挿管とい

もので、同じ呼吸の補助を行う方法でも両者は区
別されている。従つて、呼吸回路にしても各々に
独自のものがあり、両方の回路を簡便に接続し、
あるいはつなぎ替えることの出来るアダプターの
ようなものはなかつた。 The former method of forcing breathing by inserting a tube into the trachea (hereinafter referred to as tracheal intubation) is used for severely or acutely ill patients, whereas the latter method involves inhaling oxygen through the nose. is used when the patient is able to breathe spontaneously, and there is a distinction between the two even though they are the same method of assisting breathing. Therefore, each breathing circuit has its own unique characteristics, and both circuits can be easily connected.
Or, there was no such thing as an adapter that could be reconnected.
しかし、例えば、気管挿管をしている患者で
も、急性期を脱して人工呼吸器から徐々に離脱す

時に酸素濃縮器等の酸素供給源と気管チユーブを
開放式に接続すれば、自発呼吸により酸素吸入が
可能となる。
However, even when a patient is intubated, for example, when the patient is out of the acute phase and is gradually weaned from the ventilator, they may need to use an oxygen supply source such as an oxygen concentrator when they are not using the ventilator. If the tracheal tube is connected in an open manner, oxygen can be inhaled through spontaneous breathing.

陰圧式人工呼吸を行うことができる。 In addition, if the nasal cannula and tracheal tube can be connected, if a patient who is receiving home oxygen therapy using the nasal cannula is forced to undergo tracheal intubation due to acute exacerbation, after securing the airway through tracheal intubation, Furthermore, it is effective because oxygen can be inhaled on the spot, and it is also effective for patients with tracheal intubation because the nasal cannula-type breathing sensor of the negative-pressure ventilator, which is mainly used in open ventilators, can be connected to the tracheal tube. However, negative pressure artificial respiration can be performed by synchronizing breathing.

としたものである。 In order to achieve the above-mentioned problems, the present invention has been developed using tracheal tubes, L-type, Y-type,
U-type adapters, spirometers, etc.
The object of the present invention is to provide an adapter that can be connected in an open manner to an oxygen supply tube such as a nasal cannula.
