Abstract
The invention discloses a kind of drainage device for safe puncture; comprise drainage tube and the puncture body that can be contained in drainage tube and seal wire; puncture body is also provided with a tubular protective sleeve, taking in protective sleeve by puncture body by seal wire in pumpback, together takes out in pipe of leading the way.Safe drainage system of the present invention adds puncture function on the basis of drainage tube, the insert design of puncture body reduces the distress level of patient as far as possible, convenient puncture, after puncture, puncture body is extracted out from drainage tube front end through drainage tube inside by seal wire by user, carries out subsequent operation.The design of protective sleeve further ensures the stability of puncture, also prevents blade from cutting bad drainage tube by being taken in protective sleeve by blade.
Description
Technical field
The present invention relates to a kind of medical sanitary apparatus, relate in particular to a kind of drainage device for safe puncture.
Background technology
No matter drainage tube is in operative process, still after surgery treatment or rehabilitation course in be all the most frequently used device.In the use of drainage tube, modal problem is exactly coming off of drainage tube.In order to solve this problem, developed the fixture of drainage tube at body surface at present, but this fixture not only cost is high, install complicated, also can increase wound, cause wound surface even to infect.But no matter whether use this fixture, once drainage tube comes off, prior art is difficult to realize secondary puncture, is again implanted by drainage tube and locates.
Summary of the invention
Goal of the invention: in order to overcome the deficiencies in the prior art, the invention provides a kind of safe, easy to operate drainage device for safe puncture implanted by drainage tube by puncture.
Technical scheme: for achieving the above object, a kind of drainage device for safe puncture of the present invention, comprises drainage tube and the puncture body that can be contained in drainage tube and seal wire.
Puncture body of the present invention comprises the tool rest be connected with seal wire one end, and is arranged on the blade of tool rest another side.
The sphenoid shape of described blade to be front end be blade, become large gradually toward rear end thickness, this design can reduce the pain of patient in piercing process, and puncture incision is little, is beneficial to healing.
As a further improvement on the present invention, the blade of described blade forms cambered surface in front end, can cut as required in piercing process.
Conveniently pulled out by seal wire, described seal wire end is also provided with handle.
In order to provide safer operating environment, prevent the blade when seal wire and puncture body being taken out from drainage tube tail end from cutting bad drainage tube, described puncture body is also provided with a protective sleeve, this protective sleeve is tubular, the one end open of described protective sleeve is connected and installed with spiral cover by spiral, and the other end has the hole passed through for seal wire; Described spiral cover has the opening passing through for described blade and then be accommodated in protective sleeve; Described tool rest is spacing in protective sleeve by described spiral cover, is provided with rod-shaped connectors to realize the rotation of blade between blade and tool rest.When the position that blade rotates and opening are misfitted, spiral cover plays position-limiting action, facilitates blade punctures as in patient body; The position and the opening that rotate when blade are identical is rearward drawn by seal wire and blade can be realized to take in protective sleeve.Protective sleeve external diameter of the present invention is identical with the internal diameter of drainage tube or be slightly less than the internal diameter of drainage tube.
As further optimization of the present invention, described spiral cover outer surface is provided with stopper slot, and the shape of described stopper slot is similar to blade cross section.When the position that blade rotates and this stopper slot coincide, blade can embed in stopper slot, can not arbitrarily rotate, and further ensures the stability of puncture.
Puncture body of the present invention and seal wire are that metal material is made, and protective sleeve is also made for metal material, preferably based on traditional stainless steel material.Utilize the advantage of metal material to be: reusable, new drainage tube after sterilization, can be coordinated to use; The convenient B ultrasonic that coordinates of metal material carries out Needle localization, improves degree of accuracy, also reduces the misery of patient.
Beneficial effect: safe drainage system of the present invention adds puncture function on the basis of drainage tube, the insert design of puncture body reduces the distress level of patient as far as possible, convenient puncture, after puncture, puncture body is extracted out from drainage tube front end through drainage tube inside by seal wire by user, carries out subsequent operation.The design of protective sleeve further ensures the stability of puncture, also prevents blade from cutting bad drainage tube by being taken in protective sleeve by blade.

Fig. 1 is structural representation of the present invention;
Fig. 2 is the structural representation of seal wire of the present invention, puncture body and protective sleeve;
Fig. 3 is the using state figure of blade income protective sleeve;
Fig. 4 is the structural representation of spiral cover of the present invention.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is further described.
Please refer to shown in Fig. 1, Fig. 2, Fig. 3, Fig. 4, a kind of drainage device for safe puncture of the present invention, comprise drainage tube 1 and the puncture body 2 that can be contained in drainage tube 1 and seal wire 3.Seal wire 3 end is also provided with handle 7.
In the present embodiment, puncture body 2 comprises the tool rest 4 be connected with seal wire 3 one end, and is arranged on the blade 5 of tool rest 4 another side.The sphenoid shape of blade 5 to be front ends be blade 6, becomes large gradually toward rear end thickness.The blade 6 of blade 5 forms cambered surface in front end.
Puncture body 2 is also provided with a protective sleeve 8, and this protective sleeve 8 is tubular, and the one end open of protective sleeve 8 is connected and installed with spiral cover 9 by spiral, and the other end has the hole 10 passed through for seal wire 3; Spiral cover 9 has the opening 11 passing through for blade 5 and then be accommodated in protective sleeve 8; Tool rest 4 is spacing in protective sleeve 8 by spiral cover 9, is provided with rod-shaped connectors to realize the rotation of blade between blade 5 and tool rest 4.Spiral cover 9 outer surface is provided with stopper slot 12, and the shape of stopper slot 12 is similar to blade 5 cross section.
Puncture body of the present invention, seal wire and protective sleeve are all that metal material is made, convenient sterilizing, and position under B ultrasonic.
The above is only the preferred embodiment of the present invention; be noted that for those skilled in the art; under the premise without departing from the principles of the invention, can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
