Abstract
The utility model relates to the field of medical equipment, in particular to pneumoderm puncture exhaust needle, the felting needle of making including hard material, felting needle overcoat are equipped with the outer tube that soft materials made, the front end syringe needle of felting needle stretches out the front end of outer tube, the backshank of felting needle constitutes detachable the connection with the rear end of outer tube, the soft outer tube that felting needle and felting needle overcoat were established together pierces subcutaneous entering wind -puff region, impale and operate the back that finishes, the felting needle is extracted to rear end by the outer tube, make the outer tube be detained in this wind -puff region, gas in the wind -puff can conveniently be discharged by this outer tube, because the outer tube is made for soft material, the outer tube can not cause the injury to subcutaneous other tissues, soft materials's outer tube very makes things convenient for to be fixed on patient's skin, need not repeatedly can the discharge long -pending gas of wind -puff of puncture, relieves patients' pain.
Description
Technical field
The utility model relates to medical instruments field, particularly a kind of pneumoderm puncture exhaustPin.
Background technology
Clinically, mostly adopt and cut epidermis or use disposable note for the treatment of pneumodermThe mode of emitter needle pierces, implements epidermis and cuts exhaust mode, and the nursing difficulty in later stage is larger,Be easy to cause the infection of wound, and adopt the side of common disposable syringe needle pierces exhaustAlthough formula can be carried out exhaust to pneumoderm, in actual mechanical process, due to disposableSyringe needle is hard material draw point, and after this syringe needle is fixed on skin, hard syringe needle is easy toStab its subcutaneous hetero-organization of patient, therefore every venting once just need to be extracted syringe needle,In the time that wind-puff bulges again, need to, to subcutaneous puncture repeatedly, increase patient's misery.
Utility model content
The purpose of this utility model is just to provide a kind of wind-puff that avoids stabbing subcutaneous its hetero-organizationPuncture exhaust needle, is convenient to fixing to exhaust needle time, effectively eliminate the subcutaneous gas accumulating.
For realizing above object, the technical solution adopted in the utility model is: a kind of pneumoderm is wornThorn exhaust needle, comprises the pricker that hard material is made, pricker be arranged with that soft material makes outward outsidePipe, the front end syringe needle of described pricker stretches out the front end of outer tube, the rear end structure of the backshank of pricker and outer tubeBecome detachable connection.
Compared with prior art, the utility model possesses following technique effect: pricker and pricker overcoatIf soft outer tube together thrust the subcutaneous wind-puff region that enters, pierce through after end of operation, by outer tubePricker is extracted in rear end, and outer tube is trapped in this wind-puff region, the gas in wind-puff can be conveniently byThis outer tube is discharged, and because outer tube is that soft material is made, outer tube can not made subcutaneous its hetero-organizationBecome injury, the outer tube of soft material is very conveniently fixed on patient skin, without repeatedly puncturingCan discharge the pneumatosis of wind-puff, alleviate patient's misery.
Brief description of the drawings
Fig. 1 is the structural representation of pneumoderm puncture exhaust needle;
Fig. 2 is the structural representation after pneumoderm puncture exhaust needle splits;
Fig. 3 is the A-A cutaway view of Fig. 1.
Detailed description of the invention
In conjunction with Fig. 1 to Fig. 3, the utility model is done to explanation further:
A kind of pneumoderm puncture exhaust needle, comprises the pricker 10 that hard material is made, pricker 10Be arranged with the outer tube 20 that soft material is made outward, the front end syringe needle of described pricker 10 stretches out outer tube 20Front end, the backshank of pricker 10 forms detachable connection with the rear end of outer tube 20.
The outer sheathed soft outer tube 20 of pricker 10 and pricker 10 together thrusts the subcutaneous wind-puff district that entersTerritory, pierces through after end of operation, extracts pricker 10 by the rear end of outer tube 20, makes soft outer tube 20Be trapped in this wind-puff region, the gas in wind-puff can conveniently be discharged by this outer tube 20, due to outsidePipe 20 is made for soft material, and outer tube 20 can not damage subcutaneous its hetero-organization, softThe outer tube 20 of material is very conveniently fixed on patient skin, solves disposable note in prior artEmitter syringe needle is fixed on skin and causes patient's sense of discomfort. The indwelling that above-mentioned exhaust needle formsNeedle construction, without repeatedly puncturing and can discharge the pneumatosis of wind-puff, alleviates patient's misery.
For ease of outer tube 20 is thrust in pneumoderm region, the front end of described outer tube 20 isTaper.
As preferred version of the present utility model, for avoiding extraneous bacterium to enter gas by outer tube 20The infection causing in swollen region, the rear end of described outer tube 20 is provided with cap 30, described cap 30Forming detachable being fastenedly connected with outer tube 20 coordinates. When temporarily without bleeding, by capLid 30 is fixed on outer tube 20, realizes the shutoff to outer tube 20.
For convenience of operation, on described cap 30, be provided with the internal thread segment of external thread section and outer tube 20Formation is threaded.
For convenience of the operation of extracting of pricker 10. The backshank of described pricker 10 is fixed on cap 30,After puncture procedure, by pricker 10 being extracted by cap 30;
On described cap 30, be provided with holddown groove 31, the backshank of described pricker 10 is plugged on this and fixesIn groove 31. Pricker 10 without use time, pricker 10 is extracted in holddown groove 31, when withoutWhen bleeding, cap 30 is screwed on outer tube 20, realizes the shutoff to outer tube 20.
For ease of hand-held exhaust needle puncture procedure, the rear end of described outer tube 20 is provided with tabular needle handle40, this tabular needle handle 40 is convenient to hand-held time, be convenient to utilize adhesive tape that exhaust needle is fixed on to skinOn skin.
