Abstract
The utility model relates to an effusion thoracic drainage and indwelling draining device, which belongs to medical devices, and solves the technical defects that a traditional effusion thoracic drainage and indwelling draining device is not capable of cleanly pumping effusion. The utility model comprises a puncture needle and a catheter, the puncture needle comprises a casing and a needle core, and the casing comprises a soft tube, a needle plug with a two-way valve and a connecting seat. The needle core comprises a needle stem, a needle handle and a needle seat, the catheter is equipped with an adjusting valve, and the connecting seat, a needle seat interface and a catheter interface are a medical Roots interface. When puncture, the catheter and the needle core are punctured into a thorax together, firstly the two-way valve is closed and the needle core is pulled out, and then the needle core is connected with a medical injector to pump. If draining needs to be indwelled, the two-way valve is firstly closed, then the catheter interface is screwed on the connecting seat, which prevents the connecting seat interface from being polluted and is prepared for next drainage or draining. The utility model has the characteristics of scientific reasonable structure, simple structure and strong practicability and the like, and is worthy of being widely popularized and used in effusion thoracic drainage and indwelling draining.
Description
Technical field
This utility model belongs to a kind of medical apparatus and instruments, a kind of hydrops tapping, drainage from indwelling device of being suitable for.
Background technology
Clinically, require according to clinical needs for the treatment of hydrops, tapping or drainage from indwelling hydrops, tapping amount and drainage speed, drainage flow be people's state of an illness difference and having nothing in common with each other due to illness.The tradition thoracentesis needle is each hospital's self-control, and band hose and band control folder need two people behind the draw point during operation, owing to be draw point, so can not pump hydrops to greatest extent; The traditional drainage device is the plastic catheter of the rigidity trocar and rear end Band clamp, and the skin transverse incision of going ahead of the rest during operation separates subcutaneous tissue and flesh layer.Then the trocar is directly thrust in the fluid collection chamber along otch, withdraw from nook closing member, the plastic catheter of clamping the rear end is sent into the thoracic cavity.Traditional tapping of this kind and drainage system, wound is big, and hydrops can not pump, and the catheter proximal end pin hole is stopped up by pleura, cellulose and purulent core, clot sometimes, has influenced the puncture quality, even has led to complications.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned prior art defective, the device that provides a kind of tapping and drain to unite two into one, can pump the device that hydrops can be controlled drainage speed again to greatest extent according to clinical needs, shorten treatment time, the generation of as far as possible stopping complication.
The technical solution of the utility model: hydrops tapping, drainage from indwelling device, it is characterized in that: be made up of puncture needle and conduit, puncture needle is made up of paracentesis trocar and puncture nook closing member, and the paracentesis trocar front end is a flexible pipe, middle pintle for the band two-way valve, the rear end is a Connection Block.The side opening that diameter 1mm is arranged apart from flexible pipe front opening 1cm place.Two-way valve Connection Block side length 6mm, the two-way valve internal diameter is consistent with the soft tube internal diameter.The Connection Block interface is medical Lu Shi syringe interface, and mouthful end has outer silk to tighten with the cap nut of band internal thread and closely to be connected.Nook closing member by pin do, needle handle, needle stand form, hub interface also be medical Lu Shi interface, mouthful outer silk of end band also has the cap nut closely connection with it of being with internal thread, nook closing member slightly is longer than soft tube, causes its needle tip to expose, and exceeds soft tube mouth 3mm.Needle point is the plagiohedral needle point, length of needlepoint 1.5mm.Catheter head has the medical Lu Shi syringe interface of internal thread, and afterbody is provided with control valve, by regulating pulley control drainage speed.Catheter tip can closely be connected with the aseptic thin glass tube of water-sealed drainage bottle.
Further technical scheme: on the described soft tube scale is arranged.
There is anti-skidding convex line at described two-way valve knob two ends.
Described needle handle has many, and " " " type convex line is to increase skidproof effect.
Described nook closing member needle stand and trocar Connection Block all have outer silk, interface is medical Lu Shi syringe interface, needle handle below center has " imitative outer silk " consistent with external diameter in the outer silk of trocar Connection Block, just in time with the outer silk embedding of trocar Connection Block two ends with, prevent that the trocar from rotating on nook closing member.
Many convex lines of described control valve pulley are to increase skidproof effect.
The beneficial effects of the utility model are: this hydrops tapping, drainage from indwelling device can pump hydrops to greatest extent, the puncture complication reduces to greatest extent, again can be according to clinical needs drain, just can finish operation one covering device that traditional method needs two cover different devices to finish, and a people simple to operate just can finish, and drainage speed can be controlled.Show by large sample (200 example) test, use this hydrops tapping, drainage from indwelling device under identical treatment condition, rationally utilize drawing liquid and two kinds of Therapeutic Method of drain according to clinical needs, treatment time obviously shortens, and none routine complication takes place.Our unit uses this hydrops tapping, drainage from indwelling device under ultrasonic guidance, hydrops width 0.5cm, and hydrops amount 20ml all can pump and not have complication.Demonstrated fully the practicality of this device, science, it has scientific and reasonable for structure, simple to operate, characteristics such as practical are to replace old-fashioned hospital to make a kind of new equipment of traditional puncture needle and drainage system by oneself, be worth in clinical hydrops tapping, drain, extensively promoting, use.
