no. 1 approach

[0080] figure 2 A structural diagram of an embodiment of the expectoration circuit of the present invention is shown. The expectoration pipeline includes a three-way valve 4, a measurement and control pipeline 2 and a hose 9 for an expectoration machine.

[0081] The three-way valve 4 is used to connect three gas circuits: the gas circuit of the ventilator, the gas circuit of the expectorator and the gas circuit of the patient. Preferably, the three-way valve 4 is respectively connected to the ventilator, the expectoration machine and the patient through the ventilator pipeline, the expectoration machine pipeline and the patient pipeline. The expectoration machine monitors the patient's breathing condition, judges whether the patient's breathing meets the expectoration requirements, and determines the start and end time of expectoration according to the collected respiratory pressure and flow signals of the patient. When the patient breathes normally, the sputum expectorati...

no. 2 approach

[0128] Figure 15 to Figure 16 A second embodiment of the tube clip is shown. The difference from the first embodiment is that two second notched rings 42 opposite to the notches are distributed on the outer ring surface of the tube clamp main body 41 , and the optimal position of the second notched circular ring 42 is: with the tube clamp main body 41 On the outer ring opposite to the notch of the ring, and the notch of the ring of the main body 41 of the pipe clamp is symmetrical to the center of the ring of the main body 41 of the pipe clamp. The second notched ring 42 is used to fix the measurement and control pipeline 2 on the tube clip 1 by clamping, so as to achieve the purpose of fixing the measurement and control pipeline 2 on the hose 9 of the expectorant machine, so that the measurement and control pipeline 2 The layout and direction during use are more reasonable, reducing entanglement, knotting, and unexpected bending.

[0129] The notches of the two second circ...

no. 3 approach

[0161] Figure 31 Still another embodiment of the expectoration circuit of the present invention is shown. and Figure 12 Compared with the shown embodiment, the difference is that the sputum storage joint 7 is replaced by a closed sputum suction tube 23, thereby further reducing the probability of cross-infection.

Abstract

A sputum pipeline, comprising a three-way valve (4), the three-way valve (4) comprising: a body (15) with a closed space inside, on which a first port (17), a second port ( 18) and the third port (19); the elastic element (16, 23) that can close the first port (17) by deformation, the elastic element (16, 23) is arranged on the first port (17) and the body (15); and the intake and exhaust port (21) arranged on the body (15), the elastic element (16, 23) can be deformed by the intake or exhaust of the intake and exhaust port (21); measurement and control Pipeline (2), which is used to transmit the gas pressure signal collected from the three-way valve (4) to the expectorant machine, and the expectorant machine controls the inlet and exhaust ports ( 21) Intake or exhaust. The invention can realize the gas path communication between the patient, the ventilator and the sputum expectoration machine.

Description

technical field [0001] The present invention relates to a medical device, more specifically, to a sputum expectoration pipeline used for both a sputum expectoration machine and a ventilator. Background technique [0002] There are many clinical patients who partially or completely lose their ability to breathe spontaneously. Medical staff will provide them with non-invasive mechanical ventilation or invasive mechanical ventilation according to the specific situation, so as to help patients maintain breathing cycle, improve oxygenation and restore effective spontaneous breathing. Among them, invasive ventilation refers to mechanical ventilation that needs to establish an artificial airway through oral or nasal tracheal intubation or tracheotomy. After the artificial airway is established in critically ill patients, their own cough reflex is weakened, the function of heating and humidifying the upper respiratory tract is deprived, the self-cleaning effect of cilia is weakened,...
