The specific embodiment
As shown in Figure 1, 2, 3, this puncture needle is made of Fig. 1 rigidity trocar and the flexible drainage tube of Fig. 4.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 drainage tube conduit is two chambeies, one capsule pipes, form by 10 drainage catheters, 12 two-way valves, 13 Connection Blocks and 15 capsule pipes, 16 capsule interface tubes, 17 cap nuts, 10 drainage 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 drainage tube to be deviate from from the site of puncture.1 pin is done, and 10 drainage catheter outer walls all have scale, to grasp depth of needle, guarantees that 14 capsule pipe bulge branches are in the hydrops.
Use this device hydrothorax 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.Flexible drainage tube Connection Block screws on cap nut.
The 2 rigidity trocars wrap up flexible drainage tube leading portion, the overcoat soft tube, and after stirrup is anchored on the needle handle end, 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 drainage tube is sent into fluid collection chamber, see that top scale guarantees that but drainage tube 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 water-sealed drainage bottle as the need drain, utilize switch amplitude size control drainage flow size; Then connect the syringe drawing liquid as the need drawing liquid, the two-way valve switch can open or close as required; Keep somewhere as need, then close two-way valve earlier, for preventing to pollute, the hub interface cap nut of screwing in order to next drawing liquid usefulness, has reduced patient's misery.
4 as extracting drainage catheter, then extracts out with the sterilized water in the syringe holder capsule pipe earlier, extracts drainage catheter then.
