Abstract
The utility model provides a two-headed puncture drainage tube. The two-headed puncture drainage tube includes a main tube and an auxiliary tube, wherein the main tube is branched to form the auxiliary tube; the auxiliary tube and the main tube are communicated with each other and share a same entrance; a one-way valve is arranged in the main tube in a position behind the junction of the main tube and the auxiliary tube, and is used for preventing liquids from flowing out of an exit end of the main tube; the two-headed puncture drainage tube can further include a puncture needle capable of being inserted into the main tube. A puncture drainage path and an injection path can be separated through the puncture drainage tube, so as to facilitate operations, reduce the pollution, and is wide in application range.
Description
Technical field
This utility model relates to a kind of drainage tube, and particularly a kind of puncture drainage tube with two perforates of double end, can combine the function of puncture drainage, drug administration by injection, belongs to medical device technical field.
Background technology
The surgical drainage tube kind of application is a lot of clinically, can be used for urethral catheterization, wound, thoracic cavity, encephalocoele, gastrointestinal tract, biliary tract etc.Surgical drainage, in order that the pus gathering between tissue or in body cavity, blood, liquid are directed to external, prevent postoperative infection and affects wound healing.
The thoracic cavity, the abdominal puncture and drainage pipe that use clinically at present, be all one section of rubber tube or silica gel tube mostly, conventionally after puncturing, will drainage tube indwelling, and while needing drain, connect drainage bottle at the mouth of pipe; Need to aspirate with drug injection time, also can only be undertaken by the single mouth of pipe, exist the probability of polluting wound, and operation is used also comparatively inconvenience.
Utility model content
This utility model is the problems referred to above that exist for current medical drainage tube, and a kind of puncture drainage tube with two perforates of double end is provided, and reaches the object that puncture drainage and the approach of drug administration by injection are separated, and convenient operation reduces and pollutes.
Specifically, double end puncture drainage tube described in the utility model, comprise supervisor and the looped pipeline being separated by supervisor, looped pipeline communicates and has common entrance with supervisor, supervisor is positioned at supervisor and is provided with afterwards and prevents that liquid is by the check valve of being responsible for port of export outflow with looped pipeline intersection, and described double end puncture drainage tube also comprises the puncture needle that can insert in supervisor.
In this utility model, be provided with the supervisor of check valve for drug for injection in patient body, looped pipeline is for drain.
Further, described check valve comprises being arranged on is responsible for catch interior and that equate with the cross-sectional area in supervisor, the top of catch is connected by rotating shaft with supervisor's inwall and catch can rotate a certain angle to realize supervisor's folding in supervisor, on supervisor's inwall, be close to rotating shaft place and be provided with fixed block, fixed block is positioned at catch towards supervisor's port of export one side.Due to the barrier effect of fixed block, catch can only be opened to arrival end, therefore can not cause liquid to be flowed to outlet by entrance, prevents drainage-fluid adverse current.
Further, described supervisor's leading portion is that elasticity can crimping segment.
Further, described can being made up of shape memory material or elastic material by crimping segment is natural rolled state in the time inserting without puncture needle.After like this puncture needle being extracted out, this can crimping segment generation deformation be curly form, is stuck in puncture orifice place, prevents that described drainage tube from deviating from.
Further, described double end puncture drainage tube, also comprises the switch that is arranged on the looped pipeline port of export.Open switch, liquid can be discharged from the looped pipeline port of export.
Further, described switch comprises insertion switch or rotary switch.Common plug-in switch can be that perforate is set on looped pipeline, and plug-in switch is the column structure that can insert described perforate, and its diameter equates with looped pipeline internal diameter, plays sealing process when insertion, extracts switch, the liquid in looped pipeline can be discharged; Common rotary switch can, on the basis of enclosed switch, have radially discharge outlet on column structure, rotates column structure, the folding of scalable looped pipeline.
Further, described double end puncture drainage tube, also comprises the sealing cap that is arranged on supervisor's port of export.
Further, described supervisor's port of export is provided with external screw thread, and sealing cap has female thread, cooperatively interacts supervisor's port of export is sealed.
Double end puncture drainage tube described in the utility model, simple and practical, puncture drainage and drug administration by injection can be separated, avoid mutual pollution, and easy and simple to handle, can effectively prevent that drainage-fluid from flowing backwards, and can extensive use include but not limited to chest drainage or intraperitoneal drainage.
