Embodiment 1

[0039] This embodiment relates to a tracheal intubation tube with automatic expectorant removal function and an automatic expectorant removal system using it. The relevant content of the described tracheal intubation with automatic expectorant function is as follows:

[0040] The tracheal intubation tube with automatic phlegm removal function described in this embodiment specifically includes two types of ventilation pipelines; one of which is an air inlet and outlet pipeline 1, and the other is a dedicated exhaust pipeline 2; The phlegm removal device 3 is arranged on it.

[0041] The specific requirements for the tracheal intubation with automatic expectoration function also include:

[0042] In the tracheal intubation tube with automatic sputum removal function, the special exhaust pipeline 2 and / or the air inlet and outlet pipeline 1 are provided with additional structures or devices to ensure that the substances transported inside are unidirectionally transported: specif...

Embodiment 2

[0056] The content of this embodiment and embodiment 1 is basically consistent, and its main difference is:

[0057] 1) In the tracheal intubation tube with automatic sputum removal function, the air inlet and outlet pipeline 1 and / or the dedicated exhaust pipeline 2 are provided with additional structures or devices to ensure that the substances transported inside are transported in one direction: specifically, restrictions A one-way check valve that conveys a substance internally such that it can only be transferred in one direction.

[0058] 2) The parts of the air inlet and outlet pipeline 1 and the dedicated exhaust pipeline 2 of the tracheal intubation with automatic expectoration function near their respective inner openings are two relatively independent lumens sharing the same outer tube wall, which Part of the two lumens are arranged in one of the following three ways: first, the air inlet and outlet pipeline 1 and the dedicated exhaust pipeline 2 are two relatively ...

Embodiment 3

[0065] The content of this embodiment and embodiment 1 is basically consistent, and its main difference is:

[0066] 1) The inlet and outlet gas pipeline 1 and the dedicated exhaust pipeline 2 of the tracheal intubation with automatic expectorant function are two relatively independent lumens sharing the same outer tube wall, which are close to their respective inner ports. The arrangement of the two lumens of a part is a combination of the first of the following three and one of the other two (section combination): first, the inlet and outlet pipeline 1 and the dedicated exhaust pipeline 2 are in the same Inside the outer tube are two relatively independent inner tubes arranged in parallel; second, there is an inner tube inside the outer tube, which is the special exhaust pipeline 2, and the lumen formed between the outer tube and the inner tube is the air inlet and outlet pipe Road 1; thirdly, an inner tube is arranged inside the outer tube, which is the air inlet and outlet...

Abstract

The invention discloses a tracheal cannula with function of automatically eliminating phlegm, which comprises two ventilation ducts, namely an air inlet and outlet duct (1) and a special exhaust duct (2); and the special exhaust duct (2) is provided with a phlegm eliminating device (3). The invention also discloses an automatic phlegm eliminating system comprising the tracheal cannula with the function of automatically eliminating phlegm. The air inlet and outlet duct (1) and / or the special exhaust duct (2) of the tracheal cannula with the function of automatically eliminating phlegm are respectively connected with a respirator (5) or are integrated into a common duct and then connected with the respirator (5). The tracheal cannula has the function of automatically sucking the phlegm, greatly lightens the work load of medical care personnel, reduces the alarm frequency of an artificial respirator, relieves the pain of the patient due to phlegm sucking, and has low cost and great market and social values.

Description

technical field [0001] The invention relates to medical science and medical device design technology, and in particular provides a tracheal intubation tube with automatic expectorant removal function and an automatic expectorant removal system using the same. Background technique [0002] In the prior art, for patients with endotracheal intubation connected to an artificial respirator, the medical staff sucks sputum at regular intervals, which increases the workload of the medical staff, and also causes pain to the patient, causing the patient's awakening, blood pressure, and pulse changes. , and even worsen the patient's condition. People are eager to obtain a tracheal intubation tube and a corresponding device that is simple to operate and convenient for removing sputum. Contents of the invention [0003] The object of the present invention is to provide a tracheal intubation tube with automatic expectoration function and an automatic expectoration system using it, whic...
