The spiral anti-leakage drainage tube aims to solve the problem that when an existing drainage tube is used, liquid can be leaked easily along the outer wall of the drainage tube. The spiral anti-leakage drainage tube comprises an inner tube and an outer guiding tube, wherein the inner tube and the outer guiding tube are connected to form a flow path, the inner tube is composed of a tube wall, a supporting column arranged inside a tube cavity, and a connecting body between the supporting column and the tube wall, a spiral groove is formed in the tube wall from top to bottom, and the spiral groove is communicated with the tube cavity. By means of the spiral drainage structure, leakage-free drainage is achieved, and the problem that according to the existing drainage technology, body fluid is prone to aggregation on a wound, and therefore gauze replacement is needed continuously is solved.
Description
Technical field
This utility model relates to a kind of medical instrument, particularly relates to a kind of drainage tube, more specifically relates to a kind of spiral antiseep drainage tube.
Background technology
Drainage tube is generally to use after surgical operation, for by between tissue or the body cavity pus, blood, the liquid that gather be directed to externally, prevent postoperative infection and affect wound healing.The surgical drainage tube kind of application is a lot of clinically, have for urethral catheterization, have for wound, drainage tube in thoracic cavity, encephalocoele, gastrointestinal tract, biliary tract etc. have application.
But, the problem that current drainage tube exists is, between tissue or endoceliac pus, blood, body fluid etc. along the outer wall of drainage tube, flow down, in wound, gather, need the frequent gauze of changing wound, change and also easily cause not in time the pollution of clothes sometimes, this problem can not get good solution always at present.
Summary of the invention
During this utility model is used for current drainage tube, liquid easily provides a kind of drainage tube of spiral antiseep along the problem of drainage tube outer wall seepage.
Technical scheme disclosed in the utility model is as follows:
Spiral antiseep drainage tube, comprises built-in pipe, outer skirt, and described built-in pipe, outer skirt are connected to form stream; Described built-in pipe by tube wall, be arranged at intraluminal support column, and the connector between support column and tube wall forms, described tube wall offers spiral groove from top to bottom, described spiral groove is communicated with tube chamber.
Drainage tube disclosed in the utility model is different from traditional drainage tube, adopts the mode of spiral groove, utilizes the spiral groove on tube wall, body fluid drain is entered in tube chamber, and along the walking of tube chamber inner support post, by the outer skirt being connected with built-in pipe, realize the discharge of body fluid.
Between built-in pipe and outer skirt, can be integrative-structure, can be also two-part syndeton herein, when being two-part syndeton, can adopt adhering technique, also can adopt the preferred joint connection manner of the present invention.
Further, the invention also discloses described support column along the axle center setting of built-in pipe tube chamber, the connector between described support column and tube wall forms "+" shape, and support column is positioned at intersection point place.Thereby form four water conservancy diversion cavitys that size is identical, and these four water conservancy diversion cavitys are uniformly distributed, have improved water conservancy diversion efficiency.
Further, the invention also discloses preferably a kind of two-part connected mode, also include joint, described joint two ends are connected with built-in pipe, outer skirt respectively, form stream.
So-called joint connection manner, can be plug-in connected mode, can be also screwing type connected mode.
Considering on the object basis of manufacturing cost and antiseep, creatively using built-in pipe, outer skirt two-part structure, and by joint, these two parts are being connected to form to unobstructed stream.Open spiral groove is offered in utilization on the tube wall of built-in pipe, thereby endoceliac body fluid etc. can be collected in pipeline, and utilizes screw type structure ne-leakage to be drained to joint, and then is derived by outer skirt.The support column is here connected by connector with tube wall, and tube chamber is played a supporting role, and guarantees the unobstructed of after fluting built-in pipe tube chamber.
The connected mode of joint type, can optionally change built-in pipe or outer skirt, is also more suitable for medical operation simultaneously.
Further, the invention also discloses corresponding spiral groove on the inwall that described joint and built-in pipe connect and offer fluid hole; In described joint tube chamber, correspondence is formed with the support of "+" shape.Corresponding with "+" shape support column, increased integrally-built stability.
Further, the invention also discloses corresponding spiral groove on the inwall that described joint and built-in pipe connect and offer fluid hole.The mode that all adopts redundancy to coordinate between joint and built-in pipe, drainage tube, relies on extrusion friction each other its stability of card of trying hard to keep.For the built-in pipe of having offered spiral groove, the tube wall part that its part engaging with joint is unslotted, the spiral groove of liquid runs down enters into outer skirt through joint.At blank area, fluid hole is offered in the position that spiral groove and joint are joined, and neither affects fixing stability, has increased again the distribution channel of liquid, makes the drainage of intracavity liquid better.
Meanwhile, the sidewall that the invention also discloses described joint extends to built-in pipe side and outer skirt side respectively, forms tubular protection chamber.That is to say, tubular protection chamber and the end of built-in pipe and the front end of outer skirt have respectively one section of intersection, in this coincidence space, can prevent that liquid from joint, seepage occurring, and improve guide function.
Finally, we also further disclose described built-in pipe, outer skirt is structure as a whole.So-called integrative-structure, is a whole pipeline, and its one end has formed the part of outer skirt, and the other end starts gradually the outwards spiral fluting of skirt part from top, thereby forms whole spiral antiseep drainage tube structure.So not only die sinking is easy, and low cost of manufacture, is more conducive to promote.
In sum, adopt after the disclosed technical scheme of this utility model, by screw type flow guiding structure, realized ne-leakage drain, avoided in existing drainage technology, body fluid is easily assembled in wound, needs constantly to change the problem of gauze.
Accompanying drawing explanation
Fig. 1 is this utility model schematic diagram;
Fig. 2 is this utility model integral structure schematic diagram;
Wherein:
1-built-in pipe, 2-joint, the outer skirt of 3-, 10-tube chamber, 11-tube wall, 12-support column, 13-connector, the spiral groove of 14-, 20-fluid hole, 4-tubular protection chamber.
