Abstract
The utility model relates to a double lung isolating, communicating and charging and discharging foreign body multifunctional air tube, comprising a hollow tube the lower central part of that is provided with an elastic tube air bag connected with a tube air bag charging tube, the lower end of the tube is provided with a tube opening, one side of the lower end of the tube is connected with an elastic branch tube air connected with a branch tube air bag charging tube, the branch tube bag and the tube opening are respectively arranged on the two sides of the tube, the lower end of the branch tube bag is arranged with a leading-in end that is a hollow structure and provided with at least one leading-in end side hole at the rear end, the leading-in end is communicated with an absorbing tube. The utility model has the advantages that the practicability is good, the operation is easy, the controllability is good, the produce art is easy, the cost is low, and the liquid foreign body could be discharged out while operating.
Description
(1) technical field
This utility model relates to a kind of endotracheal tube when being used for open chest surgery, particularly a kind of multifunctional trachea catheter with two lung isolation, ventilation and suction foreign body.
(2) background technology
During for patient's open chest surgery, need allow the lung of operation one side temporarily stop ventilation, the carrying out of convenient operation generally stopped up the main bronchus of a side by inflatable air bag and realizes.In addition, before operation or intra-operative, also need two lungs ventilate simultaneously (gas that has anesthetics).At present, generally use double-lumen catheter to realize above-mentioned functions, just use the double channel catheter pulmonary ventilation of both sides to the left and right respectively.Its structure is: two endotracheal tubes that are fixed together side by side, an air bag that is used to isolate trachea is arranged on two endotracheal tubes, and have one to isolate bronchial air bag on bronchial catheter therein.But this double-lumen catheter has following shortcoming: 1. complex structure, manufacturing cost height.2. each endotracheal tube is thinner, is unfavorable for ventilation.3. external diameter is thicker.
The CN2004200409570 utility model patent " the dual-purpose endotracheal tube in single chamber " of inventor's invention has overcome above-mentioned shortcoming, but in operation process, produces foreign body sometimes in the lung, is difficult for discharging.
(3) summary of the invention
This utility model is in order to overcome the deficiency of above technology, provide a kind of can be in operation suction foreign body, multifunctional trachea catheter easy to use, simple in structure.
This utility model is realized by following measure:
This utility model relates to a kind of multifunctional trachea catheter, the endotracheal tube that comprises a hollow, the middle and lower part of endotracheal tube is elastic around one, be connected with the endotracheal tube air bag of endotracheal tube airbag inflation pipe, there is an endotracheal tube opening lower end of endotracheal tube, it is one elastic that lower end one side of endotracheal tube is connected with, be connected with the bronchus air bag of bronchus airbag inflation pipe, bronchus air bag and endotracheal tube opening lay respectively at the both sides of endotracheal tube, the lower end of described bronchus air bag has one to import end, its special feature is: described importing end is a hollow structure, end has at least one and imports distolateral hole, imports end and is connected with a suction catheter.
Multifunctional trachea catheter of the present utility model, the lower end of described endotracheal tube also have an endotracheal tube side opening, and endotracheal tube side opening and bronchus air bag are the same side.
Multifunctional trachea catheter of the present utility model, described endotracheal tube airbag inflation pipe, bronchus airbag inflation pipe and suction catheter all are fixed on the outer wall of endotracheal tube.
Multifunctional trachea catheter of the present utility model, the position of its endotracheal tube air bag can be in the left sides or the right side, isolate the difference of left lung or right lung according to need, select different endotracheal tubes for use.
Using method of the present utility model: multifunctional trachea catheter of the present utility model is carefully put into trachea, and the bronchus air bag imports end and inserts in the bronchus that needs isolation one side.By the endotracheal tube airbag inflation pipe, extremely trachea is sealed to the endotracheal tube airbag aeration.Feed the gas that has anesthetics by endotracheal tube to the bilateral lung, because the not inflation of bronchus air bag, gas can enter in the lung of both sides.When needs were performed the operation, by the bronchus airbag inflation pipe, to bronchus is sealed, at this moment, the lung of the side of performing the operation stopped ventilation, can undergo surgery to the bronchus airbag aeration.Intra-operative when needing the pulmonary ventilation of operation one side, with the bronchus air bag deflation, can be ventilated in the lung of operation one side.If the liquid foreign body is arranged in the sealed sides lung, suction catheter can be connected with suction pump, carry out foreign body and discharge.
Advantage of the present utility model: endotracheal tube 1. of the present utility model can go out the suction of endotracheal liquid foreign body external, easy to operate in operation.2. after having increased the bronchus air bag deflation, the ventilation sectional area of the sectional area ratio double channel catheter of its ventilation is big.3. practical, easy to operate, controllability is strong, can be used for most open chest surgeries and can obtain reliably two lungs isolating.4. be single lumen catheter owing to this utility model, thereby manufacture simply that cost is low, low price is fit to disposable use, alleviates patient's financial burden.5. can avoid reusing the unfavorable factor that its conduit brings, as cross infection etc. because of double channel catheter costs an arm and a leg.
(4) description of drawings
Fig. 1 is a structural representation of the present utility model
Among the figure, 1 bronchus airbag inflation pipe, 2 endotracheal tubes, 3 endotracheal tube side openings, 4 bronchus air bags, 5 import end, 6 endotracheal tube airbag inflation pipes, 7 endotracheal tube air bags, 8 endotracheal tube openings, 9 import distolateral hole, 10 suction catheters.
(5) specific embodiment
As shown in Figure 1, be used to isolate the structural representation of left lung for this utility model.Include the endotracheal tube 2 of hollow, the middle and lower part of endotracheal tube 2 is used to isolate trachea around one elastic, as to be connected with endotracheal tube airbag inflation pipe 6 endotracheal tube air bag 7.There is an opening endotracheal tube 2 upper ends, are used to connect gas device, and the right side, lower end of endotracheal tube 2 has an endotracheal tube opening 8, left side that one endotracheal tube side opening 3 is arranged, and are used for by bronchus lung or right lung ventilation left.The bronchus air bag 4 that left side, the lower end of endotracheal tube 2 is connected with is one elastic, be connected with bronchus airbag inflation pipe 1, the lower end of bronchus air bag 4 has a bronchus air bag to import end 5.Importing end 5 is hollow structure, terminal both sides have one and import distolateral hole 9, import end 5 and are connected with a suction catheter 10, and suction catheter is communicated with getter device, by getter device, suction catheter, the distolateral hole of importing, can easily endotracheal foreign body suction be gone out.
Endotracheal tube airbag inflation pipe 6, bronchus airbag inflation pipe 1 and suction catheter 10 all are fixed in the outer wall both sides of endotracheal tube 2.
