Problems solved by technology

However, this method will greatly increase the operation cost of the patient, and the method of opening the side vent in the later stage is very likely to cause pollution to the double-lumen endotracheal tube. When emergency treatment is required, this method will consume a lot of time, which is seriously unfavorable for emergency treatment.

Embodiment Construction

[0025] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0026] A novel double-lumen endotracheal tube, comprising a main tube 1, a branch tube 2, and a rotating tube 3.

[0027] like figure 1 As shown, the main conduit 1 is provided with a partition 1-1 extending along the length of the conduit 1, and the partition divides the main conduit 1 into a left chamber 1-2 and a right chamber 1-3, and the left chamber 1-2 The nozzle at the end is in the shape of a slope, and the nozzle at the end of the right chamber 1-3 is connected to the branch catheter 2; the left chamber 1-2 and the right chamber 1-3 are respectively provided with connectors 1-6 connected with the ventilator.

[0028] There is a main catheter cuff 1-4 on the wall of the main catheter 1, and the main catheter cuff 1-4 is provided with a main inflatable tube 1-5 for independent ventilation, and part of the main inflatable tube 1-5 is buried in t...

Abstract

The invention discloses a novel dual-cavity tracheal catheter. The novel dual-cavity tracheal catheter comprises a main catheter, a branched catheter and a rotating tube. The rotating tube can axiallyrotate in the branched catheter so as to align a side vent in the wall of the rotating tube with a pipe orifice of a variant right upper lobe, so that ventilation of the right upper lobe is facilitated; the rotating tube is powered by compressed gas, the rotating tube is rotated by an elastic force of a spring resisting the internal pressure of the compressed gas, and because the elastic force ofthe spring is related to the length of the spring, the rotating tube can be positioned to a required angle by setting the pressure of the compressed gas. The novel dual-cavity tracheal catheter is simple in structure and convenient to use, can solve the ventilation problem of a patient suffering from right upper lobe variation and reduces the surgical risks of the patient.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a novel double-lumen endotracheal catheter. Background technique [0002] The double-lumen tracheal tube is widely used in thoracic surgery. The function of the double-lumen tracheal tube is to isolate the left lung from the right lung, so that the healthy side lung can be protected from the pollution of the lung secretions or blood of the affected side. When the affected side lung and the branch duct are opened It can still ensure the effective ventilation of the healthy side lung, and can also make the affected side lung collapse faster, provide a clear surgical field, and can carry out different ventilation modes on both sides of the lung according to the needs of the disease, which is convenient for the surgeon. Operation, but also to ensure the safety of patients. According to the specific usage, the double-lumen endotracheal tube is divided into the left double-l...
