Abstract

The utility model relates to a medical instrument, which is composed of a puncture needle and a drainage tube. The puncture needle takes a hollow shape and is arranged in the middle of the drainage tube, and a needlepoint is arranged at the front end of the puncture needle and an interface which can be connected with an injector is arranged at the rear end of the puncture needle. An internal liquid outlet hole which is closely adjacent to the needlepoint is communicated with an internal liquid outlet hole arranged behind the front end of the drainage tube. The drainage tube can be made into a disposable drainage tube and can be used to puncture the thorax, the Abdominal cavity, the urinary ladder, etc and the drainage tube can be retained. The puncture tube delivers two functions as one medical instrument, has simple structure and small size, can be operated simply, can be used conveniently and causes few wounds to the patients.

Description

Multi-functional puncture drainage pipe

This utility model relates to a kind of medical equipment, but is a kind ofly to puncture and the multi-functional puncture drainage pipe of indwelling drainage tube to the human or animal specifically.

At present hospital gives patient's indwelling drainage tube, is to carry out incision of skin to be used to lead in the part basically, and then places drainage tube, and the reuse immobilization with adhesive tape is on skin, and step is cumbersome, patient is painful big, and drainage tube easily comes off, and also easily causes complication such as infection.And Chinese patent application number is 99210658 and 86203542 drainage tubes that provided, complex structure, cost height, and troublesome poeration.

The purpose of this utility model is to overcome the defective of existing puncture needle and drainage tube existence, a kind of simple to operate, accurate, rapid, fixed, minimizing complication is provided, make puncture and the one step completed two in one multifunctional puncture drainage of indwelling drainage tube pipe, and be applicable to a plurality of positions, and as: breast is worn, abdomen is worn, punctio vesicae etc.

Basis is practical to be realized according to following technical proposals.This puncture drainage pipe is made up of puncture needle and drainage tube, behind next-door neighbour's needle point a projection is arranged, and interior liquid outlet is arranged thereafter, and this hole communicates with needle lumen, and inner chamber communicates with the collar extension of outer end again, and collar extension can link to each other with syringe; The drainage tube front end is coniform, quality is harder, inner face has recessed shuttle, interior liquid outlet is arranged again, a capsula interna is arranged after again, capsula interna communicates with an intracavity pipeline, and link to each other with the outer end, in the middle of the whole drainage tube is hollow, the outer end can be made into other pipe can be connected coniform etc., drainage tube is marked with dimension mark.

Accompanying drawing is this utility model puncture drainage pipe stringer cross-sectional view

Below in conjunction with accompanying drawing this utility model is further described.The puncture drainage pipe is made up of puncture needle 12 and drainage tube 13, behind puncture needle 12 needle points 1 projection 14 is arranged, and interior liquid outlet 2 is arranged again thereafter, communicates with pin inner chamber 3 again, and 3 communicate with the collar extension 5 of rear end again, and collar extension 5 can link to each other with syringe; Drainage tube 13 wraps in puncture needle 12 outsides, and its front end 6 is coniform, and 6 inner face has recessed shuttle 15, projection 14 on itself and the puncture needle 12 matches, be interior liquid outlet 7 again, it communicates with interior liquid outlet 2 on the puncture needle 12, is capsula interna 8 after tight, it communicates with

interior tract

9,9 communicate with the import and export 10 of rear end again, and rearmost end 11 quality can be designed to coniform or helical form etc. more firmly, are convenient to be connected with other drainage tube, to adjust the length of drainage tube, also has dimension mark 4 on the drainage tube.

During use: when bladder is punctured indwelling drainage tube, when puncture drainage pipe front end 1,6 and interior

liquid outlet

2,7 enter bladder after, urine can be by interior

liquid outlet

7,2 flow in the pin inner chamber 3, flow out by collar extension 5 again, this moment can be according to the dimension mark 4 of drainage tube 13 outer bodies, come to determine how many puncture drainage pipes pushed in the bladder cavity again, make capsula interna 8 just in time all enter in the bladder cavity, at this moment can inject a certain amount of gas by drainage tube 13 external air inlet/outlet 10 usefulness syringes, capsula interna 8 is expanded in bladder cavity, and drainage tube 13 is fixed, at this moment: can be as required, aspirate with syringe 5 pairs of bladders of collar extension by puncture needle 12, flushing, injection medicine or contrast agent etc. need long-term indwelling drainage tube 13, can only puncture needle 12 be extracted to get final product.
