This double -lumen tube connects convenient to use can realize ventilating or inhaling phlegm of left and right lung and single, two lungs, accident in the reducible operation.
Description
Technical field
This utility model belongs to technical field of medical instruments, particularly relates to a kind of double lumen tube joint.
Background technology
Existing Double-lumen tracheal catheter adaptor generally includes the adapter body of tee T shape, and this adapter body one end is connected with equipment such as respirators, and the other end is provided with two catheter interfaces.These two catheter interfaces are connected with the left and right conduit of double-lumen catheter respectively, and during use, the left and right conduit of double-lumen catheter communicates with the left and right lung of patient respectively；Between one-lung ventilation and double pulmonary ventilation during switching, need to change different jointings；When one-lung ventilation if desired for during to ventilation lung suction sputum, in addition it is also necessary to take off jointing and suspend breathing.When the double pulmonary ventilation of needs, two endotracheal tubes conductings, make respirator and double excess of the lung now ventilate exchange；When patients underwent one-lung ventilation or suction sputum, it is required to change joint or close endotracheal tube with pliers folder, the most repeatedly repeatable operation not only increases the workload of doctor, and easily make endotracheal tube be subjected to displacement, cause double-lumen catheter can not separate double lung or dysventilation well, easily cause potential safety hazard.
Utility model content
Technical problem to be solved in the utility model is, overcomes the deficiency and defect mentioned in background above technology, it is provided that a kind of easy to use, can realize left and right lung and the ventilation of single, double lung or suction sputum, can reduce the double lumen tube joint of contingency in operation.
For solving above-mentioned technical problem, the technical scheme that the utility model proposes is:
A kind of double lumen tube joint, including screwed pipe joint, two three-way valve and two airway union joints, described three-way valve one end is connected with screwed pipe joint, and one end is connected with airway union joint, and the other end communicates with air.
Above-mentioned double lumen tube joint, it is preferred that described screwed pipe joint includes an end of thread and a shunting end, and described shunting end is provided with two diffluence pass, and two three-way valve insert said two diffluence pass respectively and are connected with screwed pipe joint.
Above-mentioned double lumen tube joint, it is preferred that described airway union joint is provided with a suction sputum mouth, described suction sputum mouth is unidirectional valve structure.
Above-mentioned double lumen tube joint, it is preferred that be provided with one on described airway union joint at described suction sputum mouth for opening or close the Jiao Gai of suction sputum mouth.
Compared with prior art, the utility model has the advantage of:
(1) by three-way valve, screwed pipe joint and airway union joint are attached, it is convenient to realize left and right lung and the switching of single, double pulmonary ventilation, it is not necessary to frequently take, connect double lumen tube joint, easy to use, and potential safety hazard can be reduced.
(2) by arranging the suction sputum mouth of unidirectional valve structure on airway union joint, when one-lung ventilation, the connection being not required to disconnect corrugated tubing and double-lumen catheter gets final product suction sputum；Meanwhile, gas leakage when the suction sputum mouth of this unidirectional valve structure can avoid suction catheter to enter suction sputum.
(3) by arranging Jiao Gai at suction sputum mouth, this Jiao Gai can be covered when being made without suction sputum operation, prevent from leaking gas at suction sputum mouth.

Unless otherwise defined, the implication that all technical term used hereinafter is generally understood that with those skilled in the art is identical.Technical term used herein is intended merely to describe the purpose of specific embodiment, is not intended to limit protection domain of the present utility model.
Embodiment
As shown in Figure 1, a kind of embodiment of this utility model double lumen tube joint, including one for the screwed pipe joint 1, two that is connected with the corrugated tubing of ventilation on the equipment such as respirator for the airway union joint 3 being connected with double-lumen catheter and two these screwed pipe joints 1 of connection and the three-way valve 2 of airway union joint 3.This screwed pipe joint 1 includes the end of thread 11 and a shunting end 12, this end of thread 11 is connected for ventilation corrugated tubing with the equipment such as respirator in use, this shunting end 12 is provided with two diffluence pass, and two three-way valve 2 are connected with screwed pipe joint 1 by these two diffluence pass respectively.The other two ends of this three-way valve 2 are connected with airway union joint 3 respectively and communicate with air.Three-way valve 2 is set between screwed pipe joint 1 and airway union joint 3, the switching of ventilation can be conveniently implemented between left and right lung and single, double lung by regulating this three-way valve 2, without ceaselessly taking, connect double lumen tube joint or closing endotracheal tube with pliers folder, easy to use, potential safety hazard can be reduced.
In the present embodiment, airway union joint 3 is provided with a suction sputum mouth 4, and this suction sputum mouth 4 is a unidirectional valve structure.By arranging the suction sputum mouth 4 of unidirectional valve structure, can avoid stretching into suction catheter carry out suction sputum operation time leak gas.
In the present embodiment, on airway union joint 3, at suction sputum mouth 4, it is provided with one for the glue lid 5 opening or covering this suction sputum mouth 4.When being made without suction sputum operation, cover tightly this glue lid 5, gas leakage can be prevented.
When this double lumen tube joint uses, first the ventilation corrugated tubing of the end of thread 11 of screwed pipe joint 1 with the equipment such as respirator is connected, two diffluence pass that two three-way valve 2 are shunted on end 12 by screwed pipe joint 1 respectively are connected with screwed pipe joint 1, two airway union joints 3 are connected with two three-way valve 2 respectively, the other end of two airway union joints 3 is connected with two double-lumen catheters respectively, two double-lumen catheters are inserted respectively in the left and right lung of patient, the glue lid 5 on airway union joint 3 is covered tightly；When needs carry out double pulmonary ventilation, regulate two three-way valve 2, make screwed pipe joint 1 and two airway union joints 3 communicate, can realize double lungs are ventilated；When the unilateral ventilation of needs, regulating three-way valve 2 so that the airway union joint 3 that need not ventilation side communicates with ambient atmosphere, need the airway union joint 3 of ventilation side to communicate with screwed pipe joint 1, One-lung ventilation can be carried out；When carrying out suction sputum operation, open glue lid 5, suction catheter is stretched into from suction sputum mouth 4, suction sputum can be carried out.
