Abstract
The utility model discloses a kind of tympanocentesis needle, comprise puncture needle body, be connected with negative suction system at the afterbody of puncture needle by threeway, the afterbody of described threeway first end connecting puncture needle, second end connect negative suction system, the 3rd end unsettled or connect drug injecting device.This utility model adopts threeway and negative suction system connecting puncture needle, make patient when puncture has been moved, the permutator of stirring gently in threeway can be opened negative pressure suction device, thereby realize the auto-pumping of hydrops, can connect and inject by the other end of threeway as need inject mucus eccritic, without secondary puncture, alleviate patient's misery and frightened, economic worth and use value are high.
Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, relates in particular to a kind of tympanocentesis needle.
Background technology
Along with the development of endoscopic technique; auripuncture usually completes under ear endoscope; it is clear under ear endoscope, to get a glimpse of, and secondary damage is few, and patient's left hand is held ear endoscope and spied on tympanum situation; the right hand is inserted tympanocentesis needle; usually need assistant to complete the action of extracting hydrops, now operated by two people usually can cause needle tip swing up and down, and puncture hole is strengthened; thereby be difficult to healing, even leave over the long-term disunion of the perforation of ear drum and bring inconvenience.As need inject mucus eccritic, need to carry out secondary puncture, cause unnecessary misery and frightened to patient.
Utility model content
This utility model technical issues that need to address are to provide a kind of easy to use, can extract hydrops, simultaneously also can injection of medicine, and the tympanocentesis needle that a people can operate easily.
For addressing the above problem, technical solution adopted in the utility model is: a kind of tympanocentesis needle, comprise the body of puncture needle, afterbody at puncture needle is connected with negative suction system by threeway, the afterbody of described threeway first end connecting puncture needle, second end connect negative suction system, the 3rd end unsettled or connect drug injecting device.
Described negative suction system adopts common vein automatic blood sampling pipe.
Described threeway is provided with permutator, and the first end of threeway is common port, and when permutator is closed, first end and the 3rd end communicate, and when permutator is opened, first end and the second end communicate.
The beneficial effect that adopts technique scheme to produce is: this utility model adopts threeway and negative suction system connecting puncture needle, make patient when puncture has been moved, the permutator of stirring gently in threeway can be opened negative pressure suction device, thereby realize the auto-pumping of hydrops, can connect and inject by the other end of threeway as need inject mucus eccritic, without secondary puncture, alleviate patient's misery and frightened, economic worth and use value are high.
Brief description of the drawings
Fig. 1 is this utility model structural representation;
Wherein: 1, puncture needle, 2, threeway, 3, negative suction system, 4, permutator.
Detailed description of the invention
Below in conjunction with accompanying drawing, utility model is described in further detail: as shown in Figure 1, this novel body that comprises puncture needle 1, afterbody at puncture needle is connected with negative suction system by threeway, the afterbody of described threeway first end connecting puncture needle, second end connect negative suction system, the 3rd end unsettled or connect drug injecting device.Described threeway is provided with permutator 4, and the first end of threeway is common port, and when permutator is closed, first end and the 3rd end communicate, and when permutator is opened, first end and the second end communicate.Described negative suction system adopts common vein automatic blood sampling pipe.
As embodiment more specifically, the long 7cm of piercing needle that this is novel, thickness is No. 7 syringe needle thicknesses, and pinpoint inclined plane is more blunt, and the tail end of pin is connected with the first end of threeway, and the second end of threeway is connected with vein automatic blood sampling pipe.When use, the permutator of threeway is closed, the first end of threeway is communicated with the 3rd end, and syringe needle communicates with atmosphere, and automatic blood sampling pipe is connected to threeway the second end, extract part air out and form negative pressure, puncture needle is penetrating after tympanum, by opening permutator, threeway first end is communicated with the second end, thereby syringe needle is communicated, by the negative pressure sucking-off hydrops of automatic blood sampling pipe with automatic blood sampling pipe.If need to inject eccritic before suction hydrops, threeway the 3rd end is connected to eccritic injection device, this new structure is simple, easy to use, a people gets final product complete operation, has avoided operated by two people to cause the situation that needle tip is bobbed and woven, alleviate the injury to tympanum, without secondary puncture, alleviate patient's misery and frightened, economic worth and use value are high.
Claims (2)
1. a tympanocentesis needle, comprise the body of puncture needle (1), it is characterized in that: the afterbody at puncture needle is connected with negative suction system (3) by threeway (2), the afterbody of described threeway (2) first end connecting puncture needle, second end connect negative suction system, the 3rd end unsettled or connect drug injecting device; Described threeway (2) is provided with permutator (4), and the first end of threeway is common port, and when permutator is closed, first end and the 3rd end communicate, and when permutator is opened, first end and the second end communicate.
