Abstract
The utility model relates to a sputum suction tube, which belongs to sputum suction appliances and mainly solves the technical problems that the contact surface of the external surface of a conventional sputum suction tube body and the inner side wall of a trachea is only a small arch arc surface, and is small in area, which is not favorable for sputum suction of the sputum suction tube. The sputum suction tube provided by the utility model comprises a sputum suction tube body, and is characterized in that at least one groove is formed on the external surface of the s sputum suction tube body and extends in the longitudinal direction of the sputum suction tube body. Compared with the prior art, the sputum suction tube has the benefits that since the grooves are formed on the external surface of the sputum suction tube body, the contact surface of the external surface of the sputum suction tube body and the inner side wall of the trachea is increased greatly, and sputum can be easy to suck out of the trachea through the sputum suction tube ; and since the pressure between the inner walls of the grooves and the inner side wall of the trachea is small, the sputum is easy to flow into the grooves, and the sputum is easy to suck through the sputum suction holes formed on the inner walls of the grooves. The sputum suction tube has a simple structure and good use effect, and is easy to realize.
Description
Technical field
This utility model relates to a kind of apparatus of inhaling expectorant, more specifically to a kind of sputum aspirator tube.
Background technology
As shown in Figure 5, existing sputum aspirator tube generally includes hollow tube body, at tube wall bottom, has a sputum suction hole.
Because the outer surface of body is a periphery, and the trachea medial wall is soft, and its surface also has cells such as cilium; Therefore after sputum aspirator tube inserts patient's trachea; The contact surface of the outer surface of body and trachea medial wall is merely a bit of arc surface, and its area is less, is unfavorable for that sputum aspirator tube inhales expectorant.
Summary of the invention
This utility model technical problem to be solved provides a kind of sputum aspirator tube, and this sputum aspirator tube can effectively increase the outer surface of body and the contact area of trachea medial wall, so that the sucking-off sputum.The technical scheme that adopts is following:
A kind of sputum aspirator tube comprises body, it is characterized in that: the outer surface of said body has at least one groove, and said groove is along the longitudinal extension of body.Because the trachea medial wall is soft, and its surface also has cells such as cilium, and therefore said groove makes the outer surface of body and the contact surface of trachea medial wall significantly increase, and is convenient to inhale expectorant.
More excellent scheme, said groove is parallel with the axis of body.
A kind of preferred scheme, the number of said groove are three, and each groove is along the circumferential uniform distribution of outer surface of tube body.After can guaranteeing as much as possible that like this sputum aspirator tube inserts trachea, have at least a groove and trachea medial wall to keep in touch.
For the ease of inhaling expectorant, said at least one groove inwall has at least one sputum suction hole, and each sputum suction hole is communicated with the sputum aspirator tube inner chamber respectively.
A kind of more excellent scheme, said three groove inwalls all have at least one sputum suction hole.Because pressure is less between groove inwall and the trachea medial wall, so sputum flow in the groove easily, and sputum suction hole is arranged on the groove inwall, is convenient to the sucking-off sputum.
Preferred scheme, all sputum suction holes alternately are distributed on three groove inwalls from the bottom up successively.Like this, no matter sputum is in which position, trachea medial wall, sputum suction hole can both be as soon as possible with the sputum sucking-off.
Insert length of trachea for the ease of understanding body, the outer surface of said body also is provided with row's scale.
Said scale can be a printing ink layer, and said printing ink layer is attached to the outer surface of body.
Said scale also can adopt projection, and said projection and body are made into integration.
This utility model beneficial effect against existing technologies is, owing to offer groove at the outer surface of body, makes the outer surface of body and the contact surface of trachea medial wall significantly increase, thus sputum aspirator tube more easily with expectorant from the trachea sucking-off; And with on the sputum aspirator tube groove inwall, because pressure is less between groove inwall and the trachea medial wall, so sputum flow in the groove easily, so the sputum suction hole on the groove inwall, easier sucking-off sputum; It is simple in structure, be easy to realize, result of use is very good.

The specific embodiment
Shown in Fig. 1-4, the sputum aspirator tube in this preferred embodiment comprises body 1, and the outer surface of said body 1 has three grooves 2, and said groove 2 is along the longitudinal extension of body 1, and each groove 2 is along the circumferential uniform distribution of body 1 outer surface.Because the trachea medial wall is soft, and its surface also has cells such as cilium, and therefore said groove 2 makes the outer surface of body 1 and the contact surface of trachea medial wall significantly increase, and is convenient to inhale expectorant.
Said groove 2 is parallel with the axis of body 1.
For the ease of inhaling expectorant, said three groove 2 inwalls have a plurality of sputum suction holes 3, and each sputum suction hole 3 is communicated with sputum aspirator tube inner chamber 5 respectively.Because pressure is less between groove inwall and the trachea medial wall, so sputum flow in the groove easily, and sputum suction hole is arranged on the groove inwall, is convenient to the sucking-off sputum.
All sputum suction holes 3 alternately are distributed on three groove 2 inwalls from the bottom up successively.Like this, no matter sputum is in which position, trachea medial wall, sputum suction hole 3 can both be as soon as possible with the sputum sucking-off.
Insert length of trachea for the ease of understanding body 1, the outer surface of said body 1 also is provided with row's scale 4.Each scale 4 is printing ink layer, and said printing ink layer is attached to the outer surface of body 1.
The preferred embodiment that the above is merely this utility model is not the practical range that is used for limiting this utility model; Be all equivalents of being done according to the claim scope of this utility model, be this utility model claim scope and cover.
