Abstract
The utility model discloses a B-ultrasound visual drainage catheter which comprises a catheter with an opening formed at one end and a drainage opening formed at the other end. The B-ultrasound visual drainage catheter is characterized in that an inner core is arranged in the catheter; a connector is arranged at the open end of the catheter; the inner core is inserted in the connector; and metal wires coat the wall of the catheter. The utility model has the advantages of simple structure, light weight, convenience of use for doctors, and the like.
Description
Technical field
This utility model relates to technical field of medical instruments, a kind of specifically drainage catheter.
Background technology
Drainage catheter belongs to medical apparatus and instruments, and conduit enters in the human body by body surface, the pus, blood or other liquid that gather in tissue or the body cavity can be drawn the original place by conduit, and water conservancy diversion is in external or splanchnocoel.Conduit of the present utility model belongs to external drainage, is to external technology the intracavity liquid drain.Owing in use need visual operating platform, therefore there is the requirement of development in most of medical section office to drainage catheter.Existing drainage catheter is mainly to be formed by the manufacturing of medical grade plastics, and when needing a large amount of inorganic filler of adding just can make conduit demonstrate image under B ultrasonic, but product is made difficulty and development capability is not high, and application is restricted.
Summary of the invention
The purpose of this utility model is exactly location a kind of not only simple in structure, easy, the non-easy damaged internal organs that provide for the deficiency that solves prior art, and the visual drainage catheter of effective, easy to operate B ultrasonic.
This utility model is to adopt following technical solution to realize above-mentioned purpose: the visual drainage catheter of a kind of B ultrasonic, comprise that an end is provided with the conduit that opening, the other end are provided with draining hole, it is characterized in that, be provided with inner core in the described conduit, be provided with joint at the catheter opening end, inner core inserts in the joint, is coated with metal wire in duct wall.
The coverage of described metal wire in duct wall is for to begin one until the catheter opening section from the catheter drainage mouth.
Described catheter drainage mouth is a conical tip.
Described metal wire adopts in tube wall with straight line, netted or spiral distribution, and inner core is a medical stainless steel.
Described inner core one end is a joint, and other end front end band needle point inserts catheter adapter.
The beneficial effect that this utility model adopts above-mentioned technical solution to reach is:
1, begin to be coated with the special metal wire that does not expose until catheter opening from the catheter drainage mouth in this utility model duct wall, metal wire can be with straight line, netted or spiral distribution in tube wall.Whole conduit can demonstrate image clearly under medical imaging systems such as B ultrasonic, make the conduit can be quickly and easily in endoceliac location when inserting, avoid because of locate inaccurate former thereby cause repeatedly put pipe even put problem such as tube failure.
2, conduit cooperates the inner core of stainless steel band needle point, under visualized operation platforms such as B ultrasonic, can directly carry out microtrauma puncture and put pipe, after the catheter positioning, withdraw from inner core and can carry out drainage procedure, no longer need original guiding core when putting pipe, reduce the operating time of operation.
3, because conduit does not need to add a large amount of inorganic fillers, and the hardness and the flexibility of conduit are not affected, conduit is compared with the original conduit that adds a large amount of inorganic fillers has wideer hardness range, makes conduit can wait until application in more conditions.
4, simple in structure, of the present utility model simple in structure, production technology is also very simple, and cost is low, has made things convenient for the versatility of specification

The specific embodiment
As Fig. 1～shown in Figure 4, the visual drainage catheter of a kind of B ultrasonic of this utility model, by an end be provided with conduit 1 that opening, the other end be provided with draining hole, inner core 2 in the through hole that is placed on conduit forms, inner core is a medical stainless steel, one end is a joint, other end front end band needle point inserts in the catheter adapter 3 and exposes catheter head, catheter adapter 3 is arranged on conduit 1 opening, conduit 1 other end is most advanced and sophisticated, begin to be coated with the metal wire 4 that does not expose until catheter opening from the catheter drainage mouth in conduit 1 tube wall, metal wire 4 can be with straight line, netted or spiral distribution in tube wall.
During clinical use, choose suitable position and point of puncture, sterilization, drape, local anesthesia, according to check result estimation depth of needle, vertical inserting needle reach subcutaneous after, slowly inserting needle is determined the position under the demonstration of medical imaging system is supported, after arrival location inserting needle has " falling through " sense, extract inner core 2, use fixation clamp and suture A/C, easy to operate.
Above-described only is preferred implementation of the present utility model; should be pointed out that for the person of ordinary skill of the art, under the prerequisite that does not break away from this utility model creation design; can also make some distortion and improvement, these all belong to protection domain of the present utility model.
