Description

It can brush sputum aspirator tube

Technical field

The utility model relates to medical instrument more particularly to sputum aspirator tubes.

Background technique

The negative pressure that traditional sputum aspirator tube relies solely on negative pressure source generation draws the sputum in patients with respiratory tract, when sputum ratio When more sticky, the effect of suction sputum is not satisfactory.For this purpose, people design again can brush sputum aspirator tube, it is this can brush sputum aspirator tube Tube body is made of two lumens being isolated from each other, and a lumen is connected with negative pressure source when in use, another lumen with equipped with punching The syringe of washing lotion is connected, and the outer peripheral surface of tube body is equipped with scrub part.While negative pressure source work, operator pushes injection Flushing liquor is sprayed on the respiratory tract of patient by device, and rotates tube body, so that scrub part is scrubbed respiratory tract, and then will glue The sticky sputum being attached on patients with respiratory tract is separated and is siphoned away from respiratory tract.

It is known can brush sputum aspirator tube compared with traditional sputum aspirator tube, although the effect of suction sputum can be improved, there is also Following disadvantage: 1, tube body is made of two lumens, and wherein a lumen is connected with syringe, and causing can brush sputum aspirator tube Overall volume is larger；Since tube body needs to be inserted into the respiratory tract of patient when in use, tube body volume is excessive, will necessarily reduce The use comfort of patient；2, suction sputum mouth, flushing liquor outlet and scrub part are arranged at the side of tube body, the diameter of suction sputum mouth It is difficult to do big, when suction sputum be easy to cause blocking, leads to suction sputum less effective.

Summary of the invention

That the technical problem to be solved by the utility model is to provide a kind of suction sputum effects is good, compact-sized, easily fabricated, Using more comfortably can brush sputum aspirator tube.

One embodiment according to the present utility model, provide one kind can brush sputum aspirator tube, including tube body, negative pressure source connector With flushing liquor input adapter；Tube body has the suction sputum channel being isolated from each other and passage of irrigation fluid, and the outer peripheral surface of tube body is equipped with scrub Portion；Negative pressure source connector is connected with one end of tube body, and is connected to suction sputum channel；The side phase of flushing liquor input adapter and tube body Even, it and is connected to passage of irrigation fluid；Wherein, tube body has central through hole, and central through hole constitutes suction sputum channel, and passage of irrigation fluid is set It sets in the side wall of tube body；The flushing liquor outlet for being connected to passage of irrigation fluid, scrub are offered on the end face of the tube body other end The other end of the portion close to tube body.

The utility model has at least the following advantages and feature:

1, according to the utility model embodiment can be in brush sputum aspirator tube, passage of irrigation fluid is set up directly on the side wall of tube body Inside, without two lumens, therefore overall volume is smaller, improves the usage comfort of patient；

2, for the central through hole of tube body directly as suction sputum channel, the bottom end of central through hole can be used as suction sputum mouth to use, and inhale Phlegm mouth is relatively large in diameter, and when suction sputum is not easy to result in blockage, and improves suction sputum effect；

3, due to only having a root canal body, according to the utility model embodiment can brush sputum aspirator tube manufacture it is simpler It is convenient.

Specific embodiment

Fig. 1 is please referred to Fig. 5.According to the utility model embodiment can brush sputum aspirator tube include tube body 1, negative pressure source connector 2 and flushing liquor input adapter 3.

Tube body 1 has the suction sputum channel 11 being isolated from each other and passage of irrigation fluid 12, and the outer peripheral surface of tube body 1 is equipped with scrub part 13.Suction sputum channel 11 is the central through hole of tube body 1, and the bottom end 111 of the central through hole is used as suction sputum mouth.Negative pressure source connector 2 and pipe One end of body 1 is connected, and is connected to suction sputum channel 11.Passage of irrigation fluid 12 is arranged in the side wall of tube body 1, another in tube body 1 The flushing liquor outlet 121 for being connected to passage of irrigation fluid 12 is offered on the end face at end.The other end of the scrub part 13 close to tube body 1. In the present embodiment, scrub part 13 includes lantern ring 131, and lantern ring 131 is set on the outer peripheral surface of tube body 1, and the periphery with tube body 1 Face is connected, and the mode of connection includes but is not limited to the modes such as bonding, heat seal connection.It is equipped on the periphery of lantern ring 131 multiple convex Play 132.In other embodiments, scrub part 13 is made of the multiple protrusions being arranged on tube body outer peripheral surface, it is multiple protrusion with Tube body 1 is integrally formed.

It is preferred that the end face of the other end of tube body 1 is made of the first inclined-plane 15 and the second inclined-plane 16.First inclined-plane, 15 He Second inclined-plane 16 is tilted towards tube body side, and is mutually symmetrical, the bottom end phase of the bottom end on the first inclined-plane 15 and the second inclined-plane 16 It hands over.First inclined-plane 15 and the second inclined-plane 16 can play the role of guiding, and sputum is drawn into suction sputum mouth to be more advantageous to.

Flushing liquor input adapter 3 is connected with the side of tube body 1, and is connected to passage of irrigation fluid 12.Further, according to this Utility model embodiment can brush sputum aspirator tube include catheter 4, one end of catheter 4 is connected to flushing liquor input adapter 3, leads The other end of liquid pipe 4 is connected to the side of tube body 1.Catheter 4 is thinner than flushing liquor input adapter 3.

In the present embodiment, flushing liquor input adapter 3 is made of sealing valve.Sealing valve include valve body 31, spool 32 and Return springs 33.Valve body 31 is equipped with inlet 311, liquid outlet 312 and the liquid for being connected to inlet 311 and liquid outlet 312 Runner 313.Spool 32 is arranged in valve body 31, and can move between a closed position and a open position.Spool 32 is being closed Inlet 311 is closed when position, to play the role of sealing；Inlet 311 is opened at open position, so that external inflow Flushing liquor can flow to liquid outlet 312 by inlet 311, flow channel for liquids 313.Return springs 33 are located in valve body 31, and It abuts and is connected with spool 32, which is used to often push spool 32 to closed position.Return springs 33 are preferably adopted Use spring.

In use, by can the negative pressure source connector 2 of brush sputum aspirator tube be connected with negative pressure source, and the bottom of tube body 1 is inserted into Designated position in the respiratory tract of patient.Before starting negative pressure source, first with the syringe pushing tow sealing valve equipped with flushing liquor Spool 32 makes spool 32 be moved to open position, and then flushing liquor is sprayed on the respiratory tract of patient.Flushing liquor generallys use Clean clear water.It completes after rinsing, removes syringe, sealing valve can be automatically closed again.Subsequent start-up negative pressure source starts Suction sputum rotates tube body 1 while suction sputum, by scrub part 13 by the sticky sputum being adhered on patients with respiratory tract from respiratory tract Upper separation, and then siphoned away sputum by negative pressure.

According to the utility model embodiment can in brush sputum aspirator tube, due to by the central through hole of tube body 1 directly as Suction sputum channel uses the bottom end of central through hole as suction sputum mouth, therefore, side is arranged in suction sputum mouth with the prior art Mode is compared, and the diameter of suction sputum mouth is bigger, and when suction sputum is not easy to result in blockage, and improves suction sputum effect.Further, since flushing liquor is logical Road 12 is set up directly on the interior of tube body 1, and without two lumens, therefore overall volume is also smaller, so as to improve The usage comfort of patient.
