Fig. 1 schematically illustrates a schematic diagram of a dual lumen aspiration irrigation tube according to an embodiment of the present application. Referring to fig. 1, fig. 2 schematically illustrates another schematic structural view of a dual lumen aspiration irrigation tube according to an embodiment of the present application. Referring to fig. 1 and 2, the present application provides a dual lumen aspiration irrigation tube comprising: the device comprises a double-cavity tube body 1, wherein one cavity of the double-cavity tube body 1 is a washing cavity 10, and the other cavity of the double-cavity tube body 1 is a suction cavity 20; the flushing cavity 10 and the suction cavity 20 are branched into two pipes at the upper end of the double-cavity pipe body 1, and the flushing cavity 10 and the suction cavity 20 form independent cavities which are integrally connected and not communicated with each other at the lower end of the double-cavity pipe body 1; wherein the front end of the flushing cavity 10 is provided with a flushing head joint 11, and the flushing head joint 11 is used for being connected with a flushing device; and the front end of the suction cavity 20 is provided with a suction head joint 21, and the suction head joint 21 is used for connecting with a suction apparatus.

When the device is used, the head is low, the feet are high, the reflux is prevented from invading the lung lobe section, the suction head joint 21 is connected with a suction device, the flushing head joint 11 is connected with a flushing device, then the flushing cavity 10 and the suction cavity 20 which are integrally connected and not communicated with each other are inserted into the trachea and the bronchus deep part of a patient, flushing liquid (such as flushing saline water) is sent into the flushing cavity 10 by the flushing device, and the flushing liquid is further introduced into the trachea and the bronchus deep part of the patient through the flushing cavity 10. Because the general anesthesia intubate back, the patient does not have the spontaneous breathing, and the flush fluid of inputing through washing unit can flow from the trachea deep under the action of gravity, reaches the purpose that the thing that will flow back washes totally as far as possible. Simultaneously, by the continuous suction refluxes and flush fluid of suction apparatus, the refluxes and flush fluid in trachea, bronchus of patient are introduced into suction chamber 20 to further through suction chamber 20 with refluxes and flush fluid from the suction head joint 21 suction of two-chamber body 1, thereby timely with refluxes and flush fluid suction. Through this kind of mode, compromise the suction simultaneously and wash trachea, bronchus function, when the trachea is washed, with the refluence thing and the flush fluid suction clean, shorten the time of stopping ventilating to and can go deep into trachea, bronchus deep and clear away the refluence thing as far as possible totally, make the clearance more thorough.

In a preferred embodiment, the inner diameter of the irrigation lumen 10 is smaller than the inner diameter of the aspiration lumen 20.

Specifically, referring to fig. 1 and 2, since there are residual reflux in the trachea and bronchus, when the rinsing liquid is supplied into the trachea and bronchus through the rinsing chamber 20 to wash the residual reflux, the inner diameter of the rinsing chamber 10 is smaller than the inner diameter of the suction chamber 20 in order to ensure that the reflux and the rinsing liquid can be sucked in time. Wherein, for example and without limitation, the size of the inner diameter of the aspiration lumen 20 is 1.5 times the inner diameter of the irrigation lumen 10.

In a preferred embodiment, the length of the rear end of the flushing lumen 10 is greater than the length of the rear end of the aspiration lumen 20.

Specifically, referring to fig. 1 and 2, the length of the rear end of the flushing lumen 10 is greater than the length of the rear end of the aspiration lumen 20. For example, but not limiting of, the rear end of the irrigation lumen 10 is 1cm longer than the rear end of the aspiration lumen 20. In this way, not only can the residue be effectively washed, but also the suction cavity 20 can be ensured to suck the reflux and the washing liquid in time.

In a preferred embodiment, the end of the suction cavity 20 is open, and the wall of the end of the suction cavity 20 is provided with a first through hole 22 and a second through hole 23.

Specifically, referring to fig. 1 and 2, the end of the suction chamber 20 is open, and a first through hole 22 and a second through hole 23 are formed on the upper circumference of the end tube wall of the suction chamber 20. Wherein, the first through hole 22 and the second through hole 23 are auxiliary suction ports, which enhance the suction force of the suction cavity 20 and assist the suction cavity 20 in sucking the return flow and the flushing fluid in time.

In a preferred embodiment, the distal end of the flushing lumen 10 is closed, and a plurality of side holes are formed around the wall of the distal end of the flushing lumen 10.

Specifically, referring to fig. 1 and 2, in order to prevent the reflux in the bronchus from being flushed to the far end of the bronchus, the end of the flushing cavity 10 is designed to be closed, and a plurality of side holes are formed on the circumference of the wall of the end pipe of the flushing cavity 10, so that the flushing liquid can flow out through the side holes, and the residual reflux in the deep part of the bronchus can be flushed from a plurality of different directions, thereby achieving more thorough cleaning. In addition, in the actual use process, if the condition that the tail end has no foreign matters is determined or the operator considers the benefit and the disadvantage of further flushing the far-end bronchus, the tail end closed opening can be cut off, the rear end of the flushing cavity 10 is opened, and the far-end bronchus is further flushed.

In a preferred embodiment, the wall of the end tube of the flushing cavity 10 is formed with three side holes, and the axes of the three side holes form an included angle of 60 degrees.

In a preferred embodiment, the plurality of side holes are spaced radially apart. Because the circumferential area of the tube wall of the washing cavity 10 is limited, the defect can be effectively overcome by arranging a plurality of side holes at intervals on the tube wall of the tube wall.

In a preferred embodiment, the flush head fitting 11 is adapted for connection to an infusion tee, syringe or infusion set.

In a preferred embodiment, suction tip connector 21 is a semi-sealed suction tip connector or a sealed suction tip connector. Illustratively, suction tip connector 21 in fig. 1 is a sealed suction tip connector provided with a vent conduit, a cover attachment strip, and a vent tube sealing cap. The suction head joint 21 in fig. 1 is a semi-sealed suction head joint provided with an air duct.

In a preferred embodiment, a clamping mechanism 30 is further included, and the clamping mechanism 30 is fitted over the front end of the flushing chamber 10.

Specifically, referring to fig. 1 and 2, the clamping mechanism 30 is detachably mounted at the front end of the flushing chamber 10, and when in use, the clamping mechanism 30 is adjusted to effectively block or release the flushing liquid from being fed into the flushing chamber 10, so as to achieve the purpose of controlling the flow rate of the flushing liquid according to the actual use condition.

In addition, the double-cavity suction and irrigation pipe can be set to different models according to actual use conditions, for example, but not limited to, 4 models are set, and the model is divided into 2# (2mm blue), 3# (3mm green), 4# (4mm black) and 5# (5mm white) according to the difference of the outer diameter of the double-cavity pipe body 1; and the lengths of the double-cavity pipe body 1 are 2# (32cm), 3# (34cm), 4# (36cm) and 5# (38cm) in sequence according to different models.

To sum up, the utility model provides a two-chamber suction flushing pipe compromises the suction simultaneously and washes trachea, bronchus function, when the trachea washes, will flow back thing and flush fluid suction clean, shortens and stops the time of ventilating to and can go deep into trachea, bronchus deep and clear away the flow back thing as far as possible totally, make the clearance more thorough.
