Abstract
A negative pressure fluid drainage device with puncture needle in the field of medical appliance. The utility model comprises puncture needle 5, fluid drainage tube 4 and negative pressure ball. The tail end of the puncture needle is bushed directly to the fluid drainage tube; the puncture needle can be made in the shape of straight line, camber line or obtuse angle; the puncture needle is usually made of medical stainless steel; several side ports 6 are made at the tail end of the fluid drainage tube (the part placed inside)with the diameter of side ports range in 0.5-3.0mm; the side ports can be made into round or oblong shape; a position line 8 is set in the fluid drainage tube nearby the tail end of the puncture needle; the diameter of fluid drainage tube ranges in 1-5mm; the fluid drainage tube is formed with medical plastic (which does not deform under external stress); metallic wires are embedded at the side wall of the fluid drainage tube; the negative pressure ball is connected to the fluid drainage tube with side ports; the negative pressure ball can be made into round or oblong shape. With the adoption of this utility model, no small incision needs to be added to the operating incision, thus reducing the reducing the wound ensure more smooth fluid drainage.
Description
Technical field
This utility model belongs to technical field of medical, or rather, belongs to the disposable depression drainage device improvement that surgery is used.
Background technology
In the medical operating process, the partial drain of performing the operation is a common method of disposal clinically.Original depression drainage device generally by: drainage tube and negative pressure ball are formed, generally need to do a little otch again at the other skin place of operative incision, insert drainage tube by little otch, it is local that the drainage tube end is placed on operation, the external negative pressure ball of the drainage tube other end, the material of drainage tube is a silica gel, is subjected to the external force extruding to be easy to distortion.There is shortcomings such as increasing wound face, inadequate drainage in this depression drainage device.
Summary of the invention
The objective of the invention is at above-mentioned existing problems, design a kind of depression drainage device with puncture needle.To achieve these goals, the technical solution of the utility model is: be made up of puncture needle, drainage tube and negative pressure ball.The terminal directly cover of puncture needle inserts drainage tube, and puncture needle can be made into linearity, arc shaped or obtuse angle shape, and the material of puncture needle is a medical stainless steel; Drainage tube end (inserting part in the body) has a plurality of side openings, the side opening diameter is at 0.5-3.0mm, side opening can be made into circle or ellipse, the nearly puncture needle of drainage tube end has a position line, the drainage tube diameter is at 1-5mm, drainage tube forms (it is not yielding pushed by external force) by the medical plastic typing, and the drainage tube sidewall is embedded with metal wire.Negative pressure ball is connected with the drainage tube of band side opening, and negative pressure ball can be made into spheroidal or ellipse.Advantages such as the depression drainage device of this band puncture needle has not to be needed to reduce wound at the little otch of the other increase of operative incision, and drain is more unobstructed.
Specifically in operation be, the puncture needle that will be connected to drainage tube in the operation earlier directly passes skin by the wound inboard, slowly pulls out drainage tube, treats that position line on the drainage tube exposes skin and promptly ends, and cuts puncture needle, connects negative pressure ball.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
Now in conjunction with the accompanying drawings; concrete structure of the present utility model is described below: negative pressure ball 1 links to each other with connection tube 2; drainage tube 4 is plugged in the connection tube 2; by firm 3 fixing, the front end grafting puncture needle 5 at drainage tube 4 is with protective sleeve 7 at puncture needle 5 leading sections; indicate position line 8 nearby apart from puncture needle 5 on drainage tube; on drainage tube, be cloth hole section 6 nearby apart from position line 8, above uniform diameter 0.5mm aperture, pitch-row is 10mm.Above-mentioned puncture needle 5 is the medical stainless steel pin, is curved shape, and drainage tube is the medical polyvinyl material, and the plastic tube of internal diameter 2.4mm, external diameter 3.2mm, wall thickness 0.8mm, long 500mm, negative pressure ball are the oval balls of the plastics of 100ml.
