Description

A kind of Analgesic devices

Technical field

This utility model relates to medical apparatus and instruments, relates in particular to the Analgesic devices that a kind of hospital anesthetic room uses.

Background technology

Prior art is used for dura mater anesthesia in clinical, the pipe of planting of the employing that has is a hard long tube, about one meter how long, in the use, the hard long tube of unnecessary length need be wrapped in doctor's hands, very inconvenience, and easy damaged patient notacoria, in addition, use sterilization complexity etc. repeatedly.For this reason, relevant technologies personnel have invented epidural catheter, the hard guide wire is housed in the non-toxic polyethylene conduit, the front end of flat syringe needle inserts in the conduit, tail end is fixedlyed connected with an end that prolongs pipe, and weak point is because guide hole is very little, inserts in the conduit flat syringe needle front end very difficult, back seat is an open type, easily produces pollution etc.

Summary of the invention

The purpose of this utility model provides a kind ofly can be easily to be inserted flat syringe needle front end in the conduit and avoids producing the Analgesic devices of pollution.

The purpose of this utility model can realize by following technical measures:

This Analgesic devices is equipped with the hard guide wire in conduit, the front end of flat syringe needle inserts in the conduit, and tail end is fixedlyed connected with an end that prolongs pipe, and the other end that prolongs pipe is connected with the tailstock that is connected with sealing-plug, and the port that an end and flat syringe needle are plugged in the conduit that connects is horn-like.

This utility model will be owing to will be horn-like with the port design of the slotting non-toxic polyethylene conduit that connects of flat syringe needle, thereby can make flat syringe needle front portion insert in the conduit easily, the sealing-plug that tailstock is connected with matches with through hole on the tailstock, extracts sealing-plug when needing, and inserts sealing when not required.That this Analgesic devices is made is simple, easy to use, prevent to pollute.

Description of drawings

Fig. 1 is the sketch map of this utility model embodiment.

The specific embodiment

This Analgesic devices is equipped with hard guide wire 2 in conduit 1, after inserting conduit 1 in patient's body, extract hard guide wire 2 out, front end with flat syringe needle 4 inserts in the conduit 1 again, the tail end of flat syringe needle 4 is fixedlyed connected with an end that prolongs pipe 5, and the other end that prolongs pipe 5 is fixedlyed connected with the tailstock 6 that is connected with sealing-plug 7, when needing sealing-plug is extracted from tailstock 6, insert sealing when not required again, the port of the conduit 1 of an end and flat syringe needle 4 companies of inserting is horn-like.
