China Patent No. is CN200820110992.3, publication number is CN201205380, denomination of invention is that the utility model patent of disposable rotary sputum aspirator tube discloses a kind of rotary sputum aspirator tube, this sputum aspirator tube comprises a T type tee T, bypass duct termination phlegm suction hose on the tee T, the external gas negative pressure of main road Guan Yiduan on the tee T, its other end is provided with a hollow lead that gos deep into the main road pipe, the inner of lead is provided with two toothed rack, the outer end of lead is provided with capping and spring, and the spring outer end is provided with pressure cap; The branch road pipe end is provided with the hollow axle of an insertion on the tee T, and rotating shaft the inner is provided with a gear that can cooperate with described two tooth bars, and the rotating shaft outer end is provided with plug, and phlegm suction hose passes the plug interstitial hole and is connected with hollow axle.This utility model can be simplified medical worker's operation sequence, so that realize exhausting the purpose of sputum, reduces patient suffering and infection chance.But the utility model patent of the disclosure still needs to go stifled finger-hole to control the size of negative pressure with finger, is not easy to control that it has also taken people's a hands simultaneously, makes the whole operation process be subjected to certain restriction, use inconvenient, and complex structure.
The utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art; a kind of sputum aspirator tube is provided; this sputum aspirator tube plays the purpose that can conveniently regulate negative pressure in the sputum aspirator tube; and it is simple and convenient that it inhales the expectorant operating process; and can reduce the excessive infringement of negative pressure effectively to patient respiration road mucosa; can better protect patient's physical and mental health, it also can free medical personnel or patient's a hands simultaneously, has greatly reduced operator's labor intensity.
In order to realize above-mentioned technical purpose, this utility model is realized by following technical scheme:
Sputum aspirator tube described in the utility model, comprise the threeway body, the person in charge's one end interface of described threeway body is a negative pressure source of the gas connector, the other end is the air entry that offers patient inhales, the side pipe opening part of described threeway body is an air vent, and described air vent is provided with the adjusting device of this air vent aperture size of scalable.
Further improvement as above-mentioned technology, described adjusting device is to seal the mounting of drain hole end, the partial opening that is provided with on the described mounting with definite shape, the end of described air vent also is connected with an adjusting knob, also is provided with on this adjusting knob and all identical opening of mounting upper shed shape size.
In this utility model, described mounting is located at the air vent end and forms with the side pipe integral production.Certain described mounting can be the split setting with side pipe also, is to be installed in the air vent end in addition.
As the further improvement of above-mentioned technology, opening on the described mounting and the opening on the adjusting knob are measure-alike semicircular structure.
In addition, opening on the described mounting and the opening on the adjusting knob can also be measure-alike square structure.
Compared with prior art, the beneficial effects of the utility model are:
(1) this utility model has utilized the relation of staggered folding between the mounting of sputum aspirator tube side pipe opening part and the adjusting knob cleverly; the air pressure that goes out of offside bank of tubes is regulated simply and easily; thereby reach the size of regulating the negative pressure that enters people's oral area; avoided the excessive infringement of negative pressure effectively to patient respiration road mucosa; can better protect patient's physical and mental health; it also can free medical personnel or patient's a hands simultaneously, has greatly reduced operator's labor intensity.
(2) this utility model sputum aspirator tube is simple in structure, and is easy to operate.
Description of drawings
Below in conjunction with the drawings and specific embodiments this utility model is described in detail:
Fig. 1 is this utility model sputum aspirator tube structural representation;
Fig. 2 is the vertical view after this utility model sputum aspirator tube removes adjusting knob;
Fig. 3 is the vertical view of this utility model adjusting knob;
Fig. 4 be when side pipe place opening degree is maximum in this utility model between adjusting knob and the mounting position concern corresponding sketch map;
Fig. 5 be in this utility model during side pipe place opening complete closed between adjusting knob and the mounting position concern corresponding sketch map.
The specific embodiment
As shown in Figure 1, a kind of sputum aspirator tube described in the utility model, comprise the threeway body, one end interface of threeway body is a negative pressure source of the gas connector 1, the other end is the air entry 2 that offers patient inhales, side pipe 3 opening parts of described threeway body are air vent, and described air vent is provided with the adjusting device of scalable air vent folding degree size.
In this utility model, described adjusting device is to seal the mounting 4 of drain hole 3 ends, this mounting 4 can form with side pipe 3 integral productions, certainly, mounting 4 also can be provided with the side pipe split, as long as its position that can be enclosed in the end air vent of side pipe can, and no matter how mounting 4 is provided with, the all partial opening 41 that is provided with on the mounting 4 with definite shape, and the end position corresponding to air vent also is connected with an adjusting knob 5, also is provided with on this adjusting knob 5 and all identical opening 51 of mounting 4 upper sheds, 41 shape sizes.
As shown in Figure 3, Figure 4, opening 41 on the described mounting 4 and the opening on the adjusting knob 5 51 are measure-alike semicircular structure.
In Fig. 3; rotation adjusting knob 5; when opening on the adjusting knob 5 51 and opening 41 on the mounting 4 are spun on when aiming at the position that overlaps; at this moment; the aperture maximum of air vent on the side pipe 3; be the size of semicircle opening 41 (51); when inhaling expectorant; can lay down partial pressure from the negative pressure of negative pressure gas source interface 1 by this semicircle opening 41 (51); make the negative pressure that enters patient's oral area suitably reduce, like this, for young infant patient or the more weak old patient of body constitution; can effectively avoid bigger negative pressure impulsive force, play the effect of better protect patient respiration road mucosa patient's respiratory mucosa.
As shown in Figure 4, rotation adjusting knob 5, screw the position that overlaps in misalignment fully when opening on the adjusting knob 5 51 and opening 41 on the mounting 4, at this moment, air vent is sealed up fully on the side pipe 3, makes like this from negative pressure gas source interface 1 negative pressure and can enter into the work that patient's oral area is inhaled expectorant to patient's respiratory tract completely, and it is good that it inhales expectorant work, strong drug action is applicable to physical condition patient preferably.
In addition, can also regulate the folding degree of air vent as required, adjustment process is simple and convenient, need not constantly to pin air vent with finger, can preferably staff be freed, and has reduced operator's labor intensity.
In this utility model, opening on the described mounting 4 41 can also be the identical square structure of size, ellipsoidal structure with opening 51 on the adjusting knob 5, triangular structure etc., all can with the structure that the folding degree of air vent is effectively regulated.
This utility model is not limited to above-mentioned embodiment, if various changes of the present utility model or modification are not broken away from spirit and scope of the present utility model, if these are changed and modification belongs within claim of the present utility model and the equivalent technologies scope, then this utility model also comprises these changes and modification.
