Background technology
Tracheal intubation is a kind of conventional medical apparatus and instruments, and it is inserted in trachea and by air bag intubate is fixed in trachea by the otch on trachea.Because air bag is oppressed trachea inner side for a long time, bring a lot of complication, so, someone proposes a kind of tracheal intubation of arranged side by side pair of air bag, two air bags are used alternatingly, hard pressed position in trachea can be had a rest in the situation that not interrupting respirator, well alleviated that trachea is subject to tooth for a long time and the variety of issue that brings.But two sac trachea cannulas are simultaneously for operator brings a problem, be exactly that medical personnel are when being used alternatingly air bag, owing to cannot seeing the air bag being inserted in trachea, be difficult to determine two air bags which are in inflated condition which in deflated state, once and operate miss, the air bag of having inflated is re-injected to other, can cause serious injury trachea.
Utility model content
In view of the above problems, this utility model is intended to propose a kind of tracheal intubation, when it can be inflated in two air bags, another is exitted, and can again not inflate the air bag of having inflated.
Tracheal intubation of the present utility model comprises: charge/discharge gas device, intubate; The first end of intubate is used for being inserted into trachea, and the second end of intubate is used for being connected to respirator; First end outside in described intubate is provided with the first air bag, the second air bag along its length in turn, and the first air bag, the second air bag are arranged on respectively the outside of described intubate around ground; Charge/discharge gas device comprises cavity and piston; Cavity forms column; Piston comprises piston head and piston rod, the inner side profile of the shape of piston head and the cross section of cavity adapts, piston head is arranged in cavity, and cavity is divided into the first air chamber and the second air chamber, and piston head outward flange contacts with air-tightness inside cavity and can under the effect of piston rod, along cavity, slide; Piston rod first end is connected with piston head, and the second end hermetic passes cavity and extends to the outside of cavity; The first end of cavity is formed with the first pore corresponding to the first air chamber, and the second end of cavity is formed with the second pore corresponding to the second air chamber; The first air bag is connected to the first pore by the first airway, is provided with the optionally device of open/close the first airway on the first airway; The second air bag is connected to the second pore by the second airway, is provided with the optionally device of open/close the second airway on the second airway.
Preferably, the first pore is formed on the top of cavity; The second pore is formed on the bottom of cavity.
Preferably, described intubate is further provided with baffle plate around its outside, and described baffle plate is arranged on the downstream of described the first air bag, the second air bag.
Because tracheal intubation of the present utility model comprises charge/discharge gas device, by operating the piston apparatus of this charge/discharge gas device, in the time of to an airbag aeration to another air bag deflation, and, for the air bag of having inflated, a piston head air chamber wherein moves, and it is even zero that this air chamber space is diminished, and makes medical personnel be easy to judge that the air bag that draws this air chamber connection is in inflated condition; Again, because air chamber corresponding to the air bag with inflated condition becomes very little, be even zero, from frame for movement for repeated inflation or again inflate this air bag and be provided with salvo.
Accompanying drawing explanation
Fig. 1 is the structural representation of the first embodiment of tracheal intubation of the present utility model;
Fig. 2 is the structural representation of the second embodiment of tracheal intubation of the present utility model;
Fig. 3 is the structural representation of the 3rd embodiment of tracheal intubation of the present utility model.
The specific embodiment
Below, by reference to the accompanying drawings tracheal intubation of the present utility model is elaborated.
As Figure 1-3, tracheal intubation of the present utility model mainly comprises charge/discharge gas device 20 and intubate 10.
The first end of intubate 10 is used for being inserted into trachea, and the second end 17 of intubate is for being connected to respirator.First end outside in described intubate 10 is provided with the first air bag 11, the second air bag 12 along its length in turn.The first air bag 11, the second air bag 12 are arranged on respectively the outside of described intubate 10 around ground.
Charge/discharge gas device comprises cavity 20 and piston; Cavity 20 forms column.
Piston comprises piston head 23 and piston rod 24, and the inner side profile of the cross section of the shape of piston head 23 and cavity 20 adapts, and piston head 23 is arranged in cavity 20, and cavity 20 is divided into the first air chamber 21 and the second air chamber 22.
Piston head 23 outward flanges contact with cavity 20 inner side air-tightness and can under the effect of piston rod 24, along cavity 20, slide.Piston rod 24 first ends are connected with piston head 23, and the second end hermetic passes cavity 20 and extends to the outside of cavity 20.The first end of cavity 20 is formed with the first pore 25 corresponding to the first air chamber 21, and the second end of cavity 20 is formed with the second pore 26 corresponding to the second air chamber 22.
The first air bag 11 is connected to the first pore 25 by the first airway 13, thereby the first air bag 11 is communicated with the first air chamber 21.On the first airway 13, be provided with the optionally device 18 of open/close the first airway.Optionally the device 18 of open/close the first airway can be clip, can be also valve, or for the flow regulator on tube for transfusion.The second air bag 12 is connected to the second pore 26 by the second airway 14, thereby the second air bag 12 is communicated with the second air chamber 22.Equally, be provided with the optionally device 19 of open/close the second airway on the second airway 14, optionally the device 19 of open/close the second airway can be clip, can be also valve, or for the flow regulator on tube for transfusion.
Tracheal intubation can be surrounded with in the outside of intubate 10 baffle plate 15, and baffle plate is arranged on the downstream of described the first air bag 11, the second air bag 12, and preferably, baffle plate 15 can regulate in the position of intubate 10.
In addition, the first pore 25 can be formed on the top of cavity or the outside of upper end; The second pore 26 is formed on the bottom of cavity or the outside of lower end.
In addition, also can air valve be set respectively at the first air chamber 21 and the second air chamber 22, with or venting air-breathing from outside.
During use, the first step, guarantees that two air bags, all in deflated state, insert intubate in patient's trachea.
Second step, makes the first air chamber, the second air chamber store respectively the gas of appropriate amount.
The 3rd step, makes the first air bag and the first air chamber, the second air bag and the second air chamber respectively in connected state.
The 4th step, promotes piston rod, and the gas in the first air chamber is pushed in the first air bag.
The 5th step, makes the first air bag and the first air chamber, the second air bag and the second air chamber respectively in blocking state.
The 6th step, after the scheduled time, makes the first air bag and the first air chamber, the second air bag and the second air chamber again respectively in connected state.
The 7th step, pulls piston rod, by gas suction the first air chamber in the first air bag; Meanwhile, the gas in the second air chamber is pushed in the second air bag.
The 8th step, makes the first air bag and the first air chamber, the second air bag and the second air chamber respectively again in blocking state.
Like this, just can complete replacing of an air bag.
