Abstract
The utility model discloses a kind of auripuncture vacuum suction pin, include piercing needle, syringe and negative-pressure suction pipe, piercing needle is installed on the front port of syringe, the import of negative-pressure suction pipe and the rear port of syringe connect, the outlet of negative-pressure suction pipe is connected with liquid-collecting bottle, the rear port outer surface of syringe is provided with external screw thread, nut is connected with the import of negative-pressure suction pipe, the inner surface of the nut is correspondingly provided with the internal thread being adapted with external screw thread on syringe, U-shaped filter membrane is additionally provided between the import of negative-pressure suction pipe and the rear port of syringe, the bottom of U-shaped filter membrane is intraoral towards entering for negative-pressure suction pipe, the opening fixed clamp of U-shaped filter membrane is between the internal thread of nut and the external screw thread of syringe.By using said structure, the utility model provides a kind of air-tightness preferably and can greatly promote the auripuncture vacuum suction pin of follow-up chemical examination operating efficiency.
Description
Technical field
It the utility model is related to technical field of medical instruments, and in particular to a kind of auripuncture vacuum suction pin.
Background technology
When occurring wound hydrops in human body eardrum, it usually needs draw it out, carry out related assays.It is typically at present to adopt
Extracted with injection puncture needle, but because its suction is small, finite capacity, therefore be difficult to drain only, and with larger suction
Negative-pressure suction pipe, and can not be applicable because its caliber is larger, to solve the above problems, having associated medical person by the way that negative pressure is inhaled
The import of skirt is sleeved on the back end of syringe of puncture needle and operated, but such interim overlap joint, and air-tightness is poor, is extracting
During, hydrops easily overflows from lap-joint, simultaneously as other tissue relics or clot etc. are generally also contaminated with hydrops,
Therefore the follow-up efficiency for chemically examining work can also so be substantially reduced without the extraction of filtering.
The content of the invention
In view of the shortcomings of the prior art, the utility model provides a kind of air-tightness preferably and can greatly promote follow-up chemical examination
The auripuncture vacuum suction pin of operating efficiency.
To achieve the above object, the utility model provides a kind of auripuncture vacuum suction pin, include piercing needle,
Syringe and negative-pressure suction pipe, piercing needle are installed on the front port of syringe, the import of negative-pressure suction pipe and the rear port of syringe
Connection, the outlet of negative-pressure suction pipe are connected with liquid-collecting bottle, and the rear port outer surface of syringe is provided with external screw thread, negative-pressure suction pipe
Nut is connected with import, the inner surface of the nut is correspondingly provided with the internal thread being adapted with external screw thread on syringe, and negative pressure is inhaled
It is additionally provided with U-shaped filter membrane between the import of skirt and the rear port of syringe, the bottom of U-shaped filter membrane is towards negative-pressure suction pipe
Enter intraoral, the opening fixed clamp of U-shaped filter membrane is between the internal thread of nut and the external screw thread of syringe.
The beneficial effects of the utility model are：Using said structure, because the utility model is in the import of negative-pressure suction pipe
U-shaped filter membrane is additionally arranged between the rear port of syringe, therefore can effectively filter out the other tissue relics being mingled in hydrops
Or clot etc., so as to help to lift the efficiency of follow-up chemical examination work, and the opening fixed clamp of U-shaped filter membrane is in nut
Between screw thread and the external screw thread of syringe, then it can make the connection of syringe and negative-pressure suction pipe there is good air-tightness.In addition, this reality
It is simple with new overall structure, it is easy for installation.
It is elastic hose that the utility model, which can be further arranged to described negative-pressure suction pipe, and described nut is integrally formed
It is arranged in the import of negative-pressure suction pipe.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model；
Fig. 2 is Fig. 1 A portions enlarged drawing.
Embodiment
A kind of auripuncture vacuum suction pin is given as shown in Figure 1, 2, is included piercing needle 1, syringe 2 and negative pressure and is inhaled
Skirt 3, piercing needle 1 are installed on the front port of syringe 2, and the import of negative-pressure suction pipe 3 is connected with the rear port of syringe 2, are born
The outlet of pressure suction tube 3 is connected with liquid-collecting bottle 4, and the rear port outer surface of syringe 2 is provided with external screw thread 21, negative-pressure suction pipe 3
Nut 5 is connected with import, the inner surface of the nut 5 is correspondingly provided with the internal thread 51 being adapted with external screw thread 21 on syringe 2,
U-shaped filter membrane 6 is additionally provided between the import of negative-pressure suction pipe 3 and the rear port of syringe 2, the bottom direction of U-shaped filter membrane 6 is negative
Entering for pressure suction tube 3 is intraoral, and the opening fixed clamp of U-shaped filter membrane 6 is in the internal thread 51 of nut 5 and the external screw thread 21 of syringe 2
Between.Described negative-pressure suction pipe 3 is preferably elastic hose, and described nut 5, which is integrally formed, is arranged on entering for negative-pressure suction pipe 3
On mouth.By using said structure, the utility model provides a kind of air-tightness preferably and can greatly promote follow-up chemical examination work
The auripuncture vacuum suction pin of efficiency.
Claims (2)
