Abstract
A punctured aspiration and indwelled drainage device for massive effusion belongs to the field of medical devices. The punctured aspiration and indwelled drainage device maximally avoids the complications generated by the traditional drainage device. The punctured aspiration and indwelled drainage device comprises a rigid trocar, a flexible catheter and a drainage catheter. The rigid trocar consists of two semicircular trocar tubes and is sleeved with a soft tube, and the trocar handle end thereof is fastened through a steel hoop; the flexible catheter is a two-cavity one-capsule catheter and consists of an indwelled catheter and a capsule catheter, wherein, the indwelled catheter is not communicated with the capsule catheter; and the flexible catheter is provided with a regulating valve; and a connecting seat joint, a trocar bed joint, and the catheter joints are medical Roots joints. During a puncture, the flexible catheter wrapped by the rigid trocar and fastened by the steel hoop outside is punctured into an effusion cavity. After the flexible catheter is sent into the effusion cavity, the rigid trocar is pulled out and sterile water is injected from a capsule catheter joint so that a water sac is bulged at the front end of the capsule catheter. A fastening nut is loosened to separate the rigid trocar from the soft sleeve tube. Whether the drainage catheter is connected for drainages or not depends on the clinical requirements. The punctured aspiration and indwelled drainage device has the advantages of scientific and reasonable structure, simple operation, high practicability and the like, thereby deserving a wide popularization and application in punctures, aspirations and drainages.

The specific embodiment
Shown in Fig. 1,2,3,4,5, this device is made of Fig. 1 rigidity trocar and Fig. 5 flexible conduit and drainage catheter.The rigidity trocar is made up of two semicircular needle tubings, external diameter unanimities in both, one is fluted, one has tongue, both to become a complete trocar, both have 4 needle handles by an end, the other end is a needle point.Have on 4 needle handles that " " " type convex line is to increase skidproof effect, the rigidity trocar by 1 pin do, 3 needle stands, 4 needle handles form, make by rustless steel, for preventing that the rigidity trocar from separating from the centre, keep the sharpness of needle point, there are 2 soft tubes and 6 stirrups in rigidity trocar outside, 2 soft tubes are made by polyethylene, length and nook closing member differ 3mm, and tip is made taper, make it be close to rigidity trocar outer wall.6 stirrup internal diameters are consistent with 1 rigidity trocar external diameter.Unclamp 5 clamp nuts, divide after foreign side, stirrup is enclosed within trocar needle handle end, screw 5 clamp nuts.Flexible conduit is two chambeies, one capsule pipes, form by 10 inlying catheters, 12 two-way valves, 13 Connection Blocks and 15 capsule pipes, 16 capsule interface tubes, 17 cap nuts, 10 inlying catheters are made by polyethylene or polytetrafluoroethylplastic plastic, its leading portion has three side openings, prevent to stop up conduit in the drain process, 12 two-way valves, 13 Connection Blocks, 17 cap nuts are made by the PVC material.15 capsule pipes, 16 capsule interface tubes are made by silica gel.The water pocket of 14 capsule pipe bulgings part energy bulging diameter 1.5cm stops flexible conduit to be deviate from from the site of puncture.1 pin is done, and the flexible conduit outer wall all has scale, to grasp depth of needle, guarantees that 14 capsule pipe bulge branches are in the hydrops.19 drainage catheter front ends have 18 drainage catheter interfaces, are the medical Lu Shi syringe interface of band internal thread, and the drainage catheter proximal end is provided with 20 adjusting rafts, and drainage catheter passes in the middle of adjusting raft, regulate drainage speed by regulating 21 pulleys.19 drainage catheters are that polyethylene or polytetrafluoroethylplastic plastic are made, and 18 catheter interfaces, 20 control valves, 21 pulleys are made by the PVC material.
Use this device hydrops drawing liquid, indwelling process:
1 site of puncture routine disinfection, hole, shop towel local anaesthesia are held scalpel at site of puncture transection skin, and the about 0.5cm of otch separates subcutaneous tissue and flesh layer.The flexible conduit Connection Block screws on cap nut.
2 rigidity trocars parcel flexible conduit leading portion, the overcoat soft tube, and stirrup fastening after, the trocar is directly thrust fluid collection chamber along otch, when penetrating thoracic wall or stomach wall when entering fluid collection chamber, the patient has resistance to pause to disappear sense, see the dried high scale palm of pin breast, thickness of abdominal wall, then flexible conduit is sent into fluid collection chamber, see that top scale guarantees that but flexible conduit capsule pipe bulge branch is in the hydrops, extract the rigidity trocar, inject the 3ml sterilized water, make the water pocket of capsule pipe front end bulging diameter 1.5cm from the capsule pipe joint.Unclamp clamp nut, divide after foreign side, stirrup is taken off from the rigidity trocar, the rigidity trocar is isolated from soft tube, take off.With applying ointment or plaster drainage tube is fixed in skin, because of water pocket is arranged in the hydrops, drainage tube can not deviate from, need not stitch and skin incision, both can avoid taking place the incision pain that the sutured tension causes, can prevent the drainage tube slippage again, the conduit internal orifice enter subcutaneous due to subcutaneous emphysema.
3 close two-way valve, then connect the syringe drawing liquid as the need drawing liquid, and the two-way valve switch can open or close as required; As the need drain, then close two-way valve earlier, drainage catheter interface and Connection Block interface are closely linked.The drainage catheter end can closely be connected with the aseptic thin glass tube of water-sealed drainage bottle, regulates pulley to regulate drainage speed according to clinical needs.
4 wait to pump or the clean hydrops of drain after, keep somewhere as need, then close two-way valve earlier, cap nut is twisted on Connection Block, prevent to pollute the Connection Block interface, in order to next drawing liquid or drain usefulness, reduce patient's misery.With applying ointment or plaster the trocar is fixed in skin at last.
5 according to clinical needs if will pull out drainage system, at first close two-way valve, the drainage tube interface is screwed off from the Connection Block interface, link to each other with the capsule interface tube with syringe, extract tube drawing behind the interior 3ml sterilized water of capsule pipe out.
