Abstract
The utility model relates to a rebound connecting type epidural catheter which belongs to a medical appliance for anaesthesia. The utility model is provided with a soft pipe core and an epidural catheter arranged in the soft pipe core, wherein one end of the epidural catheter is connected with the back end of a rebound bow. The utility model has the characteristics of simple structure, convenient operation and safe use.
Description
This utility model is a kind of resilience articulated epidural catheter, the medical apparatus and instruments that uses when belonging to a kind of anesthesia.
Epidural catheter is the medical apparatus and instruments that uses when the patient to operative treatment anaesthetizes.During concrete operations epidural catheter is inserted, sick through this conduit injection anaesthetic.At present the epidural catheter that uses of hospital is general adopts harder material to make, and may wear out dura mater during operation and causes full spinal anesthesia threat to life.And the Shen patent No. be in 92219857.8 the articulated epidural catheter technology employing soft tube core, this has just been avoided the damage of epidural catheter to human body, but difficult the insertion also must constantly be extracted it when inserting when using, and operation is trouble comparatively.
The purpose of this utility model is: design a kind of processing ease, resilience articulated epidural catheter easy to use.
This utility model has adopted original soft tube core and epidural catheter wherein, and the rear end of epidural catheter is connected with the rear end of resilience bow, utilizes the elastic force of resilience bow can make tube core insert, bounce back easily.The front end of said resilience bow has location hook and is used to make resilience bow location.The location hook of said front end can be " Z " shape by the bending of resilience bow.In addition, the rear end of resilience bow also can have retainer ring, is used to make the tube core location.
Below in conjunction with accompanying drawing embodiment of the present utility model is elaborated.
Fig. 1 is the front view of this utility model embodiment user mode;
Wherein, 1-retainer ring, 2-epidural catheter, 3-resilience bow, 4-tube core, 5-location hook, 6-syringe needle.
Present embodiment is made up of epidural catheter 2, resilience bow 3 and tube core 4.There is retainer ring 1 rear end of resilience bow 3, and it can bend this end bending of 3 by resilience and form; The rear end of resilience bow 3 is " Z " shape through bending, forms a location hook 5.The rear end of the epidural catheter 2 in the tube core 4 is connected in the retainer ring 1 in the resilience bow 3.Tube core 4 and epidural catheter 2 pass the pin hole on the syringe needle 6 during use, and the edge mate of location hook 5 with the syringe needle 6 of 3 front ends is bent in resilience.
The utlity model has characteristics simple in structure, easy to operate, as to use safety.
