Abstract
The utility model discloses a coelom-remained cannula puncture needle, used for the treatment of continuous drainage coelom seeper, mainly used for the refusion treatment of continuous ascites drainage of abdominal cavity interstice syndrome, abdominal cavity decompression, ascites drainage of height intestines gaseous distention, and a quantity of ascites in ascites compression abdominal cavity. The utility model comprising a puncture needle, an extension tube and a remained tube. The puncture needle, the extension tube and the remained tube are orderly sheathed from inner to outer, and the tails of the puncture needle, the extension tube, and the remained tube are in the shape of mouse tail, and the remained tube is arranged with a drainage tube and a drainage tube core. The coelom-remained cannula puncture needle has the advantages of one needle with two duties, simple operation, obvious treating effect, comfort, and safety.
Description
Technical field
This utility model relates to a kind of medical appliance, is specifically related to a kind of body cavity indwelling casing tube puncture needle, is used for the treatment of constant drainage body cavity hydrops.Be applicable to that mainly the ascites drain of the syndromic lasting ascites drain in gap, abdominal cavity, abdominal cavity decompression, height intestinal tympanites and the ascites of a large amount of ascites concentrate the intraperitoneal adoptive therapy.
Background technology
At present, still there is not special-purpose ascites drainage system clinically.Puncture draw point commonly used is done the puncture drainage treatment to patient in the hospital, because its needle point is sharp keen, and intravital other internal organs of easy damaged when constant drainage, in addition, because its needle tubing is short, be difficult for draining into the ascites in deep, especially to the patient of height intestinal tympanites, then be difficult to drain.
Utility model 00202806.9 discloses a kind of " disposable body cavity sleeve pipe puncture needle ", mainly adopts and put a drain needle guard made from nonmetallic materials again on the outer surface of former puncture needle, and its port is a round blunt shape, and is shorter than the syringe needle of steel puncture needle.Because the port of drain needle guard is a round blunt shape, be difficult for entering body cavity with puncture needle, because the drain needle guard is shorter, can not drain into the ascites in deep again.
Summary of the invention
The purpose of this utility model is the needs according to constant drainage body cavity hydrops treatment, has designed a kind of body cavity indwelling casing tube puncture needle, can reach the purpose of lasting, drain ascites to greatest extent and deep ascites, also can be used for the concentrated ascites reinfusion treatment.
This utility model is realized by following technical scheme: body cavity indwelling casing tube puncture needle described in the utility model is made of puncture needle, convergent divergent channel, indwelling tube, puncture needle, convergent divergent channel, indwelling tube be fit successively from inside to outside, its afterbody is " Mus shape of tail ", at the other end, puncture needle is provided with syringe adapter, screw-threaded coupling is established in puncture needle and convergent divergent channel junction, and indwelling tube is disk-like structure.
Put pipe and be equipped with drainage tube and drain tube core, drainage tube is a silica gel tube, the one end is provided with syringe adapter, the drain tube core is a bent steel wire, the one end is provided with nut, the drain core places in the drain, and the nut of drain tube core is locked on the syringe adapter of drainage tube, can make the fixing of drain tube core and drainage tube fit.
By the body cavity indwelling casing tube puncture needle that puncture needle, convergent divergent channel, indwelling tube constitute, by the afterbody of puncture needle and " Mus shape of tail " indwelling tube to be inserted in the body cavity, puncture needle connects the body cavity hydrops that syringe can directly be extracted superficial part out; Take out puncture needle and convergent divergent channel, insert drainage tube and drain tube core, drainage tube can be inserted the target place, reach lasting, drain ascites to greatest extent and deep ascites by the rigidity that the drain tube core is bent; A little place drainage tube and convergent divergent channel respectively by wearing, insert the ascites concentrator, can constitute the treatment loop, be used for the concentrated ascites reinfusion treatment at conventional abdomen.
Body cavity indwelling casing tube puncture needle provided by the utility model is provided with convergent divergent channel between puncture needle and indwelling tube, the three constitutes the afterbody of " Mus shape of tail ", makes indwelling tube pass through one-step method lancet puncture, expansion stomach wall, and inserts in the body; That effect by indwelling tube, drainage tube and drain tube core can reach is lasting, the purpose of drain ascites to greatest extent and deep ascites; When treatment finished tube drawing, drainage tube did not contact with stomach wall, do not have pain when extracting, and the indwelling tube that contacts with stomach wall is shorter, only for moment dull pain, had alleviated patient's misery to greatest extent when pulling out; Insert the ascites concentrator, can constitute the treatment loop, be used for the concentrated ascites reinfusion treatment.It is dual-purpose, simple to operate, evident in efficacy to have a pin, comfortable safe effect.

The specific embodiment
Present embodiment includes puncture needle, convergent divergent channel, indwelling tube.Puncture needle, convergent divergent channel, indwelling tube be fit successively from inside to outside, and the tail end of convergent divergent channel, indwelling tube is the inclined-plane guide edge, and convergent divergent channel is shorter than puncture needle, and indwelling tube is shorter than convergent divergent channel, and the afterbody 8 behind its fit is " Mus shape of tail "; At the other end, puncture needle is provided with syringe adapter 4, and the below of syringe adapter is provided with nut 2, convergent divergent channel is provided with nipple 1, the set nut 2 of puncture needle and convergent divergent channel and nipple 1 locking, indwelling tube is disk-like structure 6, is inserted in back disk-like structure 6 and withstands on the nipple 1.
Disk-like structure can not brush up against puncture wound as the protective surface of puncture wound when making the ascites drainage procedure, and the porch of disk-like structure is " loudspeaker " shape, and drainage tube is inserted in the indwelling tube easily.
Indwelling tube is equipped with drainage tube and drain tube core.Drainage tube is a silica gel tube 3, and the one end is provided with syringe adapter 5, and the other end is provided with 2-4 side opening 9 (present embodiment is for being provided with 2 side openings), and pitch-row is 1cm, and side opening is evenly distributed in both sides, and the external diameter of drainage tube is slightly less than the internal diameter of indwelling tube; The drain tube core is a bent steel wire, and the one end is provided with nut 7, and the port of the other end is a round blunt shape.
The drain tube core places in the drainage tube, and is inserted in the indwelling tube, by shape of regulating the drain tube core and the rigidity of utilizing the drain tube core, drainage tube can be brought into abdominal cavity target place, is used for continuing ascites drain and deep ascites drain.When carrying out the ascites drainage procedure, because the effect of negative pressure can make the drainage tube port be attracted to body lumen wall, cause inadequate drainage and patient's pain, by the set side opening in drainage tube end, can reduce the bigger negative pressure that the drainage tube port produces when drain ascites, guarantee the unobstructed of drain, avoid causing pain to the patient.
