Embodiment 1

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

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

[0041] The specific requirements of the tracheal intubation with automatic phlegm removal function also include:

[0042] In the tracheal intubation with automatic phlegm removal function, the dedicated exhaust pipe 2 and / or the air inlet and outlet pipe 1 are provided with auxiliary structures or devices that ensure that the substances conveyed inside are unidirectionally co...

Embodiment 2

[0056] The content of this embodiment is basically the same as that of embodiment 1, and the main differences are:

[0057] 1) In the tracheal intubation with automatic phlegm removal function, the air inlet and outlet pipe 1 and / or the special exhaust pipe 2 are provided with auxiliary structures or devices that ensure that the substances conveyed inside are unidirectionally conveyed: specifically restricted A one-way check valve that transports substances in one direction only.

[0058] 2) The parts of the air inlet and outlet pipes 1 and the dedicated exhaust pipe 2 of the tracheal intubation with automatic phlegm removal function close to their respective inner ports are two relatively independent lumens sharing the same outer tube wall. Some of the two lumens are arranged in one of the following three ways: First, the air inlet and outlet pipe 1 and the dedicated exhaust pipe 2 are two relatively independent inner pipes arranged in parallel in the same outer pipe; the second, ...

Embodiment 3

[0065] The content of this embodiment is basically the same as that of embodiment 1, and the main differences are:

[0066] 1) The air inlet and outlet pipes 1 and the dedicated exhaust pipe 2 of the tracheal intubation with automatic phlegm removal function near their respective inner ports are two relatively independent lumens sharing the same outer tube wall. The arrangement of part of the two lumens is a combination of the first one of the following three and one of the other two (segmental combination): First, the inlet and outlet air pipe 1 and the dedicated exhaust pipe 2 are in the same Inside the outer tube are two relatively independent inner tubes arranged in parallel; secondly, there is an inner tube inside the outer tube, which is the dedicated exhaust pipe 2, and the lumen formed between the outer tube and the inner tube is the inlet and outlet trachea Road 1; Third, an inner tube is provided inside the outer tube, which is the air inlet and outlet pipe 1, and the l...

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 marketand social values.

Description

Technical field [0001] The invention relates to medical science and medical device design technology, and in particular provides a tracheal intubation with an automatic sputum removal function and an automatic sputum removal system using it. Background technique [0002] In the prior art, for patients with tracheal intubation connected to an artificial respirator, medical staff will suck sputum every time interval, which increases the workload of medical staff, and at the same time causes pain to the patient, causing the patient's awakening, blood pressure, and pulse changes , And even cause the patient's condition to deteriorate. People are eager to obtain a simple operation, convenient tracheal intubation and corresponding device for removing sputum. Summary of the invention [0003] The purpose of the present invention is to provide a tracheal intubation with automatic sputum removal function that can be applied in the clinical field and an automatic sputum removal system usin...
