A kind of disposable breast, intraperitoneal drainage deviceTechnical field
This utility model relates to medical instruments field.
Technical background
Puncture drainage and medicine injection that prior art is done hydrothorax, ascites are internist's working ranges, usually take simple thoracic-puncture needle puncture, repetitious drawing water, and patient is painful big.Or ask the surgeon to do thoracic wall or celiotomy incision and place drainage tube, on thoracic wall, and drainage tube is thicker with the drainage tube sutured, and wound is big, and the enforcement of drain is difficult in time carry out inconvenient operation.Drainage tube needs to be connected with drainage bottle, does not infect because of the sterile working does not thoroughly cause hydrothorax or ascites easily, and the puncture of single is drawn water.Because of the short time extracts a large amount of hydrothorax patients out and can not tolerate, so be difficult to hydrothorax or ascites suction clean.Owing to above reason, most of breasts, ascites patient can not be got timely medical treatment.
Summary of the invention
The disposable splanchnocoel drainage device that this utility model provides possesses following characteristics: the physician can be independently complete operation easily.Drainage tube is thin, special-purpose puncture needle with supporting design is assisted puncture, drainage tube, syringe, drainage bag are combined, with two water pockets fixedly drainage tube on thoracic wall, do not need surgical stapling, the drainage speed may command possesses drain and medicine injection dual-use function, the thoracic cavity is upper and lower respectively places a drainage tube, can do chest drainage, perfusion and flushing.The drainage tube front end has metal flag, can adjust repeatedly under perspective.After drainage tube blocked, available contrast agent was washed drainage tube open under perspective.
The purpose of this utility model can realize by following measure: drainage tube tail end and drainage bag are connected, the drainage bag tail end has discharging valve, the drainage tube front end has metal marker, be connected with conduction hole, preceding water pocket, back water pocket, preceding water injection valve, back water injection valve, injection valve successively backward again, movably speed governing clamp is arranged behind the injection valve, on the forward and backward water pocket inner drainage tube sidewall water injection hole is arranged, water injection hole is connected by water injection pipe with water injection valve, and water injection pipe and drainage tube join.
The specific embodiment
During use, at first determine patient's chest or abdominal part site of puncture, partly sterilised, the band sterile gloves, the shop aseptic hole-towel, after the local anesthesia, with blade site of puncture skin is cut an osculum to subcutaneous tissue, the two halves circular casing of autoclave sterilization is connected into a circular casing, be enclosed within on the puncture needle nook closing member, the retaining head is pressed close to needle handle, again circular fixed cover is enclosed within telescopic outside to retaining head place, further fixed sleeving, hold needle handle, thumb, forefinger pinches sleeve pipe, from knife-edge part puncture needle is firmly punctured to the thoracic cavity, when subtracting empty sense, resistance occurs, show that puncture needle is to enter the thoracic cavity, at this moment pull out the needle handle nook closing member, the left hand thumb, forefinger pinches sleeve pipe and is fixed, and the drainage tube that the right hand is slightly littler than sleeve pipe with the disinfectant diameter is inserted thoracic cavity or abdominal cavity 10～15cm by front end, the right hand is held drainage tube and is fixed it again, left hand slowly rotates extracts sleeve pipe, passes through preceding water injection valve with syringe, preceding water injection hole water filling 5～25ml, preceding water pocket is full, outwards pull out drainage tube, water pocket is close to the thoracic wall inboard before making, and two semicircle puncture casing are removed, and the reuse syringe is by the back water injection valve, back water injection hole water filling 5～25ml, the back water pocket is filled, and being close to the thoracic wall outside, drainage tube can be fixed on the thoracic wall by two water pockets like this, unclamps speed governing clamp, at this moment hydrothorax can flow to drainage bag from the high thoracic cavity of pressure, local with aseptic husky cloth wrapping, by clip drainage bag is fixed on patient bedside, drainage bag is full of the back and discharges water by discharging valve.If do the thoracic cavity irrigation, can respectively place a drainage tube in the homonymy thoracic cavity up and down, above a transfusion, below a drain.Through one day or a couple of days that hydrothorax or ascites drain is clean, whether drain is clean also can further to confirm breast, ascites by perspective or B ultrasonic, can chemotherapeutics or other medicines be injected thoracic cavity or abdominal cavity by the injection valve after clean, close speed governing clamp before it earlier, suitably observation is reactionless, and is at last that preceding water pocket liquid suction is clean, extracts drainage tube, sterile gauze wrapping after the partly sterilised, otch is healing automatically.
Fig. 1 is a sketch map of the present utility model.Wherein: 1-discharging valve, 2-drainage bag, 3-clip, 4-speed governing clamp, 5-drainage tube, 6-injection valve, 7-back water injection valve, 8-preceding water injection valve, 9-back water injection pipe, 10-back water injection hole, 11-back water pocket, 12-preceding water injection pipe, 13-preceding water injection hole, 14-preceding water pocket, 15-conduction hole, 16-metal flag, 17-front end.
