Detailed Description
The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.
Referring to fig. 1-7, a dual-channel extension tube of a respirator comprises a connecting conduit 1, a respirator connector 2 for communicating with a respirator and a T-shaped connector 3 for communicating with an airway of a human body; a spacer 10 is fixedly arranged in the connecting conduit 1 along the radial direction, and the spacer 10 divides the connecting conduit 1 into an air inlet cavity 11 and an exhalation cavity 12; the two ends of the connecting conduit 1 are fixedly provided with connecting plugs 13, the middle of each connecting plug 13 is provided with an air inlet channel 14 and an air outlet channel 15 in a penetrating manner, and the air inlet channel 14 and the air outlet channel 15 are respectively communicated with the air inlet cavity 11 and the expiration cavity 12; connecting tube 1 both ends are connected end cap 13 and breathing machine connector 2 and "T" type connector 3 through two respectively and can dismantle the connection, with breathing machine connector 2 is connected the internal fixation of passageway 15 of giving vent to anger of connecting end cap 13 is provided with one towards one-way flap 4 of ventilating of breathing machine connector 2, with "T" type connector 3 is connected the intake passage 14 internal fixation of connecting end cap 13 is provided with one towards one-way flap 4 of ventilating of "T" type connector 3.
Further, be provided with the external screw thread on connecting the lateral wall of end cap 13, all fixedly on breathing machine connector 2 and "T" type connector 3 be provided with in-band threaded connecting cylinder 5, two connect end cap 13 respectively with breathing machine connector 2 and "T" type connector 3 threaded connection.
Further, a sealing washer 6 is fixedly arranged on the outer side wall of the connecting plug 13; the sealing washer can prevent the gas leakage caused by the untight connection between the connecting plug 13 and the connecting cylinder 5.
Further, the connecting conduit 1 is a telescopic conduit, and the spacer 10 is a telescopic blade; a plurality of reinforcing rings 16 are fixedly arranged on the inner side wall of the connecting conduit 1 at intervals, so that the connecting conduit is prevented from being blocked due to excessive deformation of the connecting conduit.
The working principle of the utility model is as follows:
the extension tube of the respirator is connected with the respirator through a respirator connector 2, gas output from an air inlet tube of the respirator is conveyed to a connecting plug 13 connected with the respirator connector 2, and because a one-way ventilation valve 4 facing the respirator connector 2 is arranged on an air outlet channel 15 of the connecting plug 13, the sucked gas only enters an air inlet cavity 11 in a connecting guide tube 1 from an air inlet pipeline 14 and is transmitted to the air inlet channel 14 of the connecting plug 13 connected with a T-shaped connector 3 and enters the T-shaped connector 3 through the one-way ventilation valve 4; the gas exhaled from the human body airway is conveyed to the connecting plug 13 connected with the T-shaped connector 3, and because the unidirectional ventilation valve 4 facing the T-shaped connector 3 is arranged in the air inlet channel 14 of the connecting plug 13, the exhaled gas only enters the exhalation cavity 12 in the connecting conduit 1 from the air outlet pipeline 15 and enters the respirator connector 2 through the unidirectional ventilation valve 4 on the connecting plug 13 connected with the respirator connector 2; the inhaled and exhaled gas is not in the same loop, so that mechanical ineffective cavities are reduced, and the gas exchange efficiency is improved.
When the connecting conduit 1 needs to be cleaned or replaced, the connecting plugs 13 at the two ends of the connecting conduit 1 can be unscrewed, and the connecting conduits can be divided into three parts for cleaning or replacement, so that the cleaning efficiency can be improved, and the recycling rate can be increased.
