Abstract

The utility model relates to a drainage system, in particular to a percutaneous drainage flusher, which comprises a drainage tube in which the front end is provided with a convergence mouth. A puncture needle is jacketed inside the lumen of the drainage tube, in which the front end is provided with an awl. The front end of the awl is punched out from the convergence mouth. The outer surface of the drainage tube is indicated from the front to the rear with a length graduation mark. The utility model is with simple structure. The awl of the puncture needle is used for the guide puncture to reduce the trauma. In addition, on the outer surface of the drainage tube, the graduation mark is provided and the corresponding numbers are indicated. Thus the depth of insertion can be clearly showed. The utility model is communicated to a washing liquor to flush the afflicted part. The sanies concentration is diluted, and the flushing is thorough. The utility model can also be communicated to a liquid medicine for medicine treatment, so that the speed of recovery of patient can be accelerated. The utility model is widely applied in hospital clinical drainage process with lower cost, which is easy for implementation and promotion. The good socail and economic benefits can be obtained after the popularization.

Description

The puncture drainage flusher

One. technical field: this utility model relates to a kind of drainage system, particularly relates to a kind of puncture drainage flusher.

Two. background technology: when people because of pneumothorax, acute empyema, liver abscess, peritoneal abscess, muscle depths abscess etc., perhaps after the operation, need chest drainage from inner chamber, to discharge pus or gas, the general syringe that adopts is taken out, perhaps adopt drainage tube to effluxing, when pus or gas more, and do not stop production when living, adopting syringe to take out needs multi-pass operation, very inconvenient, need be when adopting drainage tube at the skin upper cut, Cao Zuo incision wound is bigger like this, gives patient's wound more serious, is unfavorable for healing, can't clearly illustrate the degree of depth that drainage tube inserts when inserting drainage tube simultaneously, inserted shallowly, evacuation of pus is not thorough, inserts dark, damage other internal organs, often cause big misery to the patient.

Three. the content of utility model:

The purpose of this utility model: overcome the defective of prior art, provide a kind of simple in structure, easy to use, can show the puncture drainage flusher that inserts length and skin puncture.

The technical solution of the utility model: a kind of puncture drainage flusher, contain drainage tube, the drainage tube front end is provided with the convergence mouth, in the drainage tube inner chamber, be set with puncture needle, this puncture needle front end is provided with pointed cone, the front portion of pointed cone passes from the convergence mouth, indicates the length graduation mark from front to back at the drainage tube outer surface.

Puncture needle is followed successively by pointed cone, neck bar, shank and back seat from front end, wherein the neck shank diameter greater than pointed cone at the bottom of the footpath, and less than the drainage tube internal diameter, shank can be solid hopkinson bar, or is hollow stem, the rear end diameter of back seat is greater than point diameter.

Pointed cone can be the rhizoma sparganic taper.

Be provided with the side opening of some in the anterior tube wall opposite flank of drainage tube.

Graduation mark is marked with corresponding length numeral.

The beneficial effects of the utility model:

This utility model simple in structure, reduce wound.Adopt this utility model skin incision littler than general otch, behind the incision of skin, the pointed cone guiding of utilization puncture needle penetrates, because the neck shank diameter of puncture needle is greater than the diameter of drainage tube convergence mouth, can prevent that puncture needle from exerting oneself to wear off drainage tube and the damaged tissue organ when excessive, so the puncture needle band drainage tube and enter the inner chamber diseased region, extract puncture needle then out, connecting drainage bottle can use, therefore simple in structure, easy enforcement.

2. this utility model can show the degree of depth that drainage tube inserts, and uses very convenient.Owing on the drainage tube outer surface, be provided with graduation mark and indicate corresponding digital, can show the degree of depth of insertion significantly, can not occur shallowly or dark excessively, caused when shallow, discharge not thoroughly, when mistake is dark, damage other internal organs, cause unnecessary misery to the patient.

3. this utility model can be communicated with flushing liquor by threeway, and the affected part is washed, and dilution pus concentration is cleaned thoroughly, also can be communicated with medicinal liquid, carries out Drug therapy, accelerates sick body recovery from illness speed.

4. this utility model is widely used in the hospital clinical drain process, and cost is lower, and promotion and implementation easily have good society and economic benefit after the popularization.

Four. description of drawings:

Fig. 1 is the structural representation of puncture drainage flusher

Fig. 2 is the use principle figure of puncture drainage flusher shown in Figure 1

Five. the specific embodiment:

Embodiment: referring to Fig. 1 and Fig. 2, among the figure, drainage tube 1 adopts medium hardness silica gel or polyethylene to make, and its front end is provided with the convergence mouth, is set with puncture needle 2 in drainage tube 1 inner chamber, these puncture needle 2 front ends are provided with pointed cone 3, pointed cone 3 can be the rhizoma sparganic taper, and the front portion of pointed cone 3 passes from the convergence mouth, is provided with length graduation mark 7 from front to back at drainage tube 1 outer surface, and be provided with corresponding length numeral, be provided with three side openings 8 in the anterior tube wall opposite flank of drainage tube 1.

Puncture needle 2 is followed successively by pointed cone 3, neck bar 4, shank 5 and back seat 6 from front end, wherein neck bar 4 diameters are greater than footpath, 3 ends of pointed cone, because neck bar 4 diameters are greater than the diameter of drainage tube 1 convergence mouth, can prevent that puncture needle 2 from exerting oneself to wear off drainage tube 1 and the damaged tissue organ when excessive, shank 5 can be solid stainless steel, or is hollow stainless steel, pointed cone 3 and neck bar 4 are made for solid rustless steel, the rear end diameter of back seat 6 is made by the hard polyethylene plastics greater than point diameter, the puncture of can conveniently exerting oneself.

Drainage tube 1 internal diameter can be 6,7,8,9, five kinds of specifications of 10mm, external diameter is 8,9,10,11,12mm, a front end convergence mouthful diameter is 4～8mm, side opening 8 is the elliptical aperture of major axis 7～10mm, minor axis 5～8mm, apart from drainage tube 1 front end is 15mm, 35mm, and drainage tube 1 appearance indicates graduation mark 7 every 10mm.

The pointed cone 3 of puncture needle 2 is about 8mm, cone bottom diameter 4～8mm, and the little 1mm of internal diameter of the corresponding drainage tube 1 of the diameter of neck bar 4 is about 20mm, shank 5 diameters are 3～6mm, long 180mm, and back seat 6 point diameters are 6～10mm, long 15mm, end diameter is 16mm, is about 10mm.

During use, carry out local anesthesia, cut skin 10mm then in definite drain site of puncture, drainage tube 1 is inserted in puncture needle 2 inserting needle that vertically or a little tilts, show the degree of depth of inserting according to graduation mark 7, determine that drainage tube 1 enters into correct position after, withdraw from puncture needle 2, clamp drainage tube 1 rear end, skin suture, fixedly drainage tube 1, and drainage tube 1 and drainage bottle 9 are connected, can carry out drain, the pus in the inner chamber is discharged.

Flushing if desired, drainage tube 1, drainage bottle 9 and corresponding cleaning liquid bottle 10 are communicated with threeway 11 respectively, the inlet of clamp drainage bottle 9 makes flushing liquor enter inner chamber, and diseased region is washed, and dilution pus, then, close the tube for transfusion of cleaning liquid bottle 10, the pus of dilution is entered in the drainage bottle 9, so several is carried out in circulation, can make flushing more thorough.

Add medicinal liquid if desired, as long as it is flushing liquor is replaced with required medicinal liquid, very convenient.
