Problems solved by technology

The reason is that during non-invasive ventilation, there is no artificial airway, and the positive pressure airflow can push the sputum to the deep airway. Speaking, the problem of expectoration restricts the clinical application of non-invasive ventilation technology, and at the same time increases the incidence of non-invasive ventilation to invasive ventilation, increases the pain of patients, increases the rate of nosocomial infection, and increases the risk of ventilator-related injuries and Incidence of ventilator-associated pneumonia, increased ICU length of stay and hospital costs

Embodiment Construction

[0035] The present invention will be further described below with reference to specific embodiments. It should be understood that the following examples are only used to illustrate the present invention and not to limit the scope of the present invention.

[0036] like figure 1 As shown, the minimally invasive bedside sputum suction device of the present invention includes a Seldinger puncture assembly and a cannula 1, the cannula 1 is sleeved outside the Seldinger puncture assembly, and the outer opening of the cannula 1 is provided with a one-way valve 2 .

[0037] like figure 1 and Figure 7 As shown, the one-way valve 2 is matched with the valve cap 31 of the sealed suction pipe 3 .

[0038] The cannula 1 is provided with a bent portion 11 , and the outer diameter of the bent portion 11 is provided with a back hole 111 .

[0039] The cross-sectional shape of the back hole 111 is a center-symmetric four-pointed star.

[0040] The maximum distance from the center of th...

Abstract

The invention discloses a minimally invasive bedside sputum suction device and relates to the technical field of medical instruments. The minimally invasive bedside sputum suction device comprises a Seldinger puncture assembly and an intubation, wherein the intubation is sleeved outside the Seldinger puncture assembly; and a check valve is arranged at an external opening of the intubation. A channel with the outer diameter of 6mm is punctured into a membrane part between third and fourth tracheal rings in middle of a neck by a seldinger technology; and the external opening is connected with the check valve and then is connected with an airtight sputum suction tube. The device can rotate 15 degrees toward left and right in tracheas.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a minimally invasive bedside sputum suction device. Background technique [0002] For severe pneumonia, elderly patients and long-term bedridden patients generally have a problem of sputum fatigue and poor expectoration. Especially in patients with pulmonary infection, effective expectoration is particularly important for infection control. The usual measures are: 1. The application of expectorant and expectorant drugs. 2. Pat the back, and inhale the drug by atomization. 3. Active phlegm suction in the oropharynx, stimulation of the cricothyroid membrane in the throat to assist in expectoration. 4. The artificial airway is established and the suction tube is used to actively suck the sputum. However, the above treatment measures have many difficulties and limitations. In measures 1 and 2, patients still need to actively expectorate sputum in the end, but when expect...
