Abstract

The present invention provides a leakage prevention and fixation free bead string type drainage tube which is mainly used for breast vomica drainage or other body cavity drainage after the operation of female breast cancer in the medical field. The drainage tube of the present invention is composed of a guide tube and a bursa body which are combined in a whole, and are made of silica gel or rubber materials. The bursa body comprises an imperforate wall ball bursa body and a preforated wall ball bursa body; the full length of the drainage tube is 40cm; the part at the front 20cm of the drainage tube is arranged outside bodies and is an imperforate guide tube; the part at the rest 20cm of the drainage tube is a preforated beaded guide tube and is arranged in bodies; one bursa body with beaded bulge tube walls is arranged every 5cm, and the tube wall of the bursa body is provided with holes; an imperforate wall ball bursa is arranged in the middle, and the wall thickness of the guide tube and the bursa body is from 1 to 3mm. The present invention solves the problems easy leakage generation and fixation requirement, and the area of drainage holes is increased through the ball-shaped bursa; especially, when the negative pressure is exerted on the drainage tube, the effect of leakage prevention and blockage prevention is more obvious; when used, the present invention can achieve the purpose of alleviating patient's pain and decreasing relevant complicating diseases.

Description

Leakage-preventing fixation-free bead string type drainage tube

Technical field

Be mainly used in medical domain female breast breast carcinoma postoperative, the drain of breast vomica, the principle of present technique also can extend to the drain that especially is subjected to vacuum suction, as drain or the like behind gastrointestinal decompression drain, chest drainage, intraperitoneal drainage and the thyroid operation.

Background technology

Seepage takes place in present widely used Traditional Female mammary breast cancer postoperative, breast vomica drain common rubber tube drain commonly used easily, needs to fix, and uses inconvenience, needs to cut on pipe processed such as hole.When drainage tube was imposed vacuum suction, it is flat that tube chamber becomes, thereby be easy to take place the drain seepage, brings great inconvenience for patient and clinicist, also might cause infection.

Summary of the invention

In order to overcome fixing trouble of traditional drainage pipe and the easy deficiency that seepage takes place, originally provide a kind of dribbling capsule leakproof that obviously is different from the traditional drainage pipe in shape to exempt from fixed drainage tube, it can be made of described conduit and described utricule one, described conduit and utricule communicate, and are arranged to just can have every a segment distance the porose utricule of a bulge inserting the body inner segment; And the central site of drainage tube is set to an imperforate wall sacculus body, has the effect of closed surgery draining hole during this utricule uses.

Described drainage tube adopts silicon to mould or elastomeric material is made, be the leakage-preventing fixation-free bead string type structure, total length 40cm, comprise following 3 coherent parts, be divided into according to function: the imperforate wall sacculus body that is positioned at the intermediate point position, the side that the sacculus one links to each other is the conduit of atresia on the tube wall, and an other side is a beading conduit with holes, is beading sacculus shape.The imperforate wall sacculus body in site in the middle of being positioned at, diameter is 1.8cm.The conduit of the side pipe wall atresia that the sacculus one links to each other, its internal diameter is 1.3cm, can do drain usefulness outward by lead body, and can attract with external central negative pressure or the vacuum suction ball is connected by connection tube.The side beading conduit with holes that the sacculus one links to each other can design as follows: comprise the nonporous conduit on cyst wall sacculus body with holes and the connection sacculus.Connect the nonporous conduit of sacculus, bore is 1.3cm.The sacculus body design with holes of described cyst wall is as follows: can 1 porose sacculus body of this kind beading be set every 5cm, described porose sacculus body diameter is 1.5cm, all is provided with the conduction hole that diameter is 0.5cm on the tube wall of sacculus body upper and lower, left and right four direction.The thickness of the wall of the above conduit and described utricule is 1mm entirely, also can be marked with graduation mark at the body subscript of described drainage tube.Not only having by this drainage tube of above design need not fixed function, also possesses good leak preventing effect.

Because of the present invention can be arranged to an imperforate wall sacculus to drainage tube central authorities site by mould,, can not influence the drainage effect of integral body again so both can reach the fixedly purpose of drainage tube and leakproof by sacculus.In addition, for ease of drain, the drain end of this drainage tube (inserting endoceliac drain pipeline section) can be designed to have a plurality of sacculus bodies, and sacculus is provided with conduction hole, thereby increases the drain area.The using method of this drainage tube is that the atresia sacculus in drain end and drainage tube central authorities site is put into the body cavity of human body operation, and is connected with external central negative pressure suction pump or vacuum suction ball by putting with the drainage tube of external end.

The invention has the beneficial effects as follows, the traditional drainage pipe is prepared into has the catenate drainage tube of several sacculus, not only having solved it seepage takes place easily and needs the fixed difficult problem of needlework, but also conduction hole by increasing on the sacculus body, thereby increased the area of drain, particularly when drainage tube was imposed vacuum suction, this pre-antiseep was just more outstanding with the effect that prevents to stop up.

The specific embodiment

Drainage tube 1 of the present invention, as Fig. 1, Fig. 2 and shown in Figure 3, employing silicon moulds or elastomeric material is made.This drainage tube 1 is made of conduit 2 and utricule 3 one, begin just have one section conduit to expand from inside to outside every the distance of 5cm from the central point of conduit 2 and form utricule 3 to a side, the pipe that is positioned at conduit 2 centre is made an imperforate wall sacculus body 4, apart from each 20cm of two-port, its diameter is 1.8cm, one side of imperforate wall sacculus body 4 is a nonporous conduit, and the above-mentioned utricule 3 that is positioned at these imperforate wall sacculus body 4 opposite sides is all made porose squash utricule 5, and its diameter is 1.5cm.Porose squash utricule 5 its sacculus bodies all have conduction hole 6 up and down separately, the diameter in this hole is 0.5cm, and with the tube chamber conducting of inside.

The internal diameter of conduit 2 is 1.3cm, total length 40cm, and the thickness of the wall of conduit 2 and utricule 3 is 1mm, the spacing between each utricule 3 is 5cm, and the body subscript of drainage tube is marked with graduation mark.

Drainage tube 1 is the leakage-preventing fixation-free bead string type structure.When in use, all utricules are all put in the body of human body, be responsible for drainage tube 1 is fixed under the otch of human body surface by the imperforate wall sacculus body 4 that is positioned at central point, because of being a sacculus body, when being subjected to outside tractive, utricule is born against on otch, thereby reach the effect that prevents seepage, can not come off, also can not cause the obstruction of wound.Again because except that imperforate wall sacculus body 4, other utricule all is porose squash utricule 5, promptly all be respectively arranged with conduction hole 6 up and down at sacculus, so not only increased the area of drain, under the situation about also stopping up simultaneously there being indivedual conduction holes 6 to be extruded, can not cause the obstruction of drain point, thereby reach better drainage effect, and be connected with external central negative pressure suction pump or vacuum suction ball by connection tube.
