Abstract
The utility model provides a trachea cannula and relates to a medical device. The trachea cannula comprises a catheter (1), the front end of the catheter (1) is provided with a guiding head (2) and an air outlet hole (3), the rear end of the catheter (1) is provided with an air inlet hole (4), an outer wall of the catheter (1) is provided with an air bag (5) at the back of the guiding head (2), a suction connector (6) is arranged at the rear end of the outer wall of the catheter (1), an air suction channel (7) is arranged in a wall of the catheter (1), the rear end of the air suction channel (7) is connected with the suction connector (6), the front end of the air suction channel (7) is provided with an inner air suction hole (8) and an outer air suction hole (9) in a wall in front of the air bag (5), and the inner air suction hole (8) and the outer air suction hole (9) are respectively communicated with the inside and the outside of the catheter. The trachea cannula has the advantages of being simple in structure, convenient to use and capable of effectively removing sputum and sputum scab adhering to a trachea wall.
Description
Technical field
This utility model relates to medical apparatus and instruments, is specifically related to a kind of tracheal intubation that Pneumology Department is used that is applicable to.
Background technology
Endotracheal intubation is a kind of endotracheal anesthesia and the technology that gives emergency treatment to a patient, is also the reliable means that keeps upper respiratory tract unobstructed.But when operation, often can run into patient's lower respiratory tract secretions and form a scab and stop up trachea, need to attract in time operation.Owing to inserting the trachea using at present, be all single channel, breathe and attract the same passage that adopts, cause denseer sputum and expectorant crust to be attached on tracheal wall and be difficult to be attracted out.
Summary of the invention
Technical problem to be solved in the utility model is: for the problems referred to above, provide a kind of remover that can effectively absorb expectorant crust.
Technical solution of the present utility model is: it comprises conduit, the front end of conduit is provided with target seeker and venthole, the rear end of conduit is provided with air inlet, the outer wall of described conduit is provided with air bag in target seeker rear, the outer wall of conduit is provided with attraction joint in rear end, in catheter wall, be provided with air intake passage, air intake passage rear end is connected with attracting joint, and the wall of air intake passage front end in air bag the place ahead is provided with interior suction hole and outer suction hole is communicated with the inside and outside of conduit respectively.
Technique effect of the present utility model is: it has advantages of simple in structure, easy to use and can effectively remove sputum and the expectorant crust being attached on tracheal wall.Each self-separation of respiration channel and attraction channel, is independent of each other, and the two crosses in end, and attraction channel and respiration channel form loop in intersection, is just conducive to remove thick sputum liquid and the expectorant crust of intersection, makes respiratory tract keep unimpeded.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, it comprises conduit 1, the front end of conduit 1 is provided with target seeker 2 and venthole 3, the rear end of conduit 1 is provided with air inlet 4, the outer wall of described conduit 1 is provided with air bag 5 in target seeker 2 rears, and the outer wall of conduit 1 is provided with in rear end and attracts joint 6, in conduit 1 wall, is provided with air intake passage 7, air intake passage 7 rear ends are connected with attracting joint 6, and the wall of air intake passage 7 front ends in air bag 5 the place aheads is provided with interior suction hole 8 and outer suction hole 9 is communicated with the inside and outside of conduit respectively.
Described interior suction hole 8 bores are less than outer suction hole 9, are beneficial to outer hole and produce larger suction.
This utility model can adopt medical grade rubber to make.Breathe with the passage attracting and separate, independent separately, because the two crosses at target seeker 2 places, when brute force is air-breathing, can be directly and respiration channel formation loop, when removing expectorant crust, can not injure lung.For increasing air intake passage 7, can adopt the structure of many channel parallels.Because thick sputum degree is higher, in the situation that strengthening suction, in intersection, can produce compared with strong suction, make sputum gradually by whole sucking-off.
Claims (2)
1. tracheal intubation, comprise conduit (1), the front end of conduit (1) is provided with target seeker (2) and venthole (3), the rear end of conduit (1) is provided with air inlet (4), it is characterized in that, the outer wall of described conduit (1) is provided with air bag (5) in target seeker (2) rear, the outer wall of conduit (1) is provided with in rear end and attracts joint (6), in conduit (1) wall, be provided with air intake passage (7), air intake passage (7) rear end is connected with attracting joint (6), the wall of air intake passage (7) front end in air bag (5) the place ahead is provided with interior suction hole (8) and outer suction hole (9) is communicated with the inside and outside of conduit respectively.
2. tracheal intubation as claimed in claim 1, is characterized in that, described interior suction hole (8) bore is less than outer suction hole (9).
