Abstract
The utility model discloses a disposable umbilical vein trocar, which is characterized in that the disposable umbilical vein trocar comprises a sleeve outer needle and a sleeve inner needle. The sleeve inner needle body is made of metal and is inserted in the sleeve outer needle, and the tail end of the sleeve inner needle body aligns with the tail end of the sleeve outer needle body. The sleeve outer needle body is made of nontoxic plastics, and a ring-shaped groove is disposed at a combination part of the sleeve outer needle body and the needle handle. The sleeve outer needle body has a certain toughness. The tail ends of the sleeve inner needle body and the sleeve outer needle body are both provided with a non-tip flat head. The disposable umbilical vein trocar is low in cost, simple in use, safe and reliable in performance, and convenient in popularization.
Description
Technical field
This utility model belongs to technical field of medical instruments, is specifically related to a kind of disposable umbilical vein trocar, is applicable to medical clinical umbilical cord intravenous administration injection.
Background technology
The umbilical vein injecting drug use is that neonate rescues, the important technology operation of treatment; At present mainly with the general injection needle umbilical vein injecting drug use that outside umbilical cord, punctures; Because the normal injection needle tip is sharp keen; Syringe needle usually punctures umbilical vein and causes medication failure in the process of injecting drug use, simultaneously because umbilical cord is very smooth is difficult for fixed needle at the syringe needle that puncture successfully afterwards and is prone to deviate from blood vessel.
Summary of the invention
In order to overcome the deficiency of above-mentioned existing technology, the purpose of this utility model provides a kind of disposable umbilical vein trocar.
For achieving the above object; The technical scheme that this utility model is taked is that this disposable umbilical vein trocar is made up of pin in the outer pin of sleeve pipe, the sleeve pipe; Needle body is processed with metal and is inserted in the outer needle body of sleeve pipe in the sleeve pipe, and the end of needle body and the outer needle body of sleeve pipe is terminal concordant in the sleeve pipe.
The outer needle body of said sleeve pipe is processed with non-toxic plastic, and there is a ring-like groove joint portion of needle body and needle handle sleeve pipe outside, and sleeve pipe needle body outward has certain toughness.
Needle body, outer needle body end are no sharp tack in the said sleeve pipe.
Because the terminal concordant blood vessel that is difficult for puncturing of this utility model needle body, overcome the normal injection needle tip sharp keen in the process of injecting drug use syringe needle usually puncture the defective that umbilical vein causes the medication failure; This utility model has a ring groove in the joint portion of needle body and needle handle simultaneously; During use the broken ends of fractured bone of the disposable umbilical vein trocar from neonatal umbilical cord inserted in the umbilical vein; With operation suture thread with umbilical vein together with the umbilical cord ligation in the ring groove of the needle body of overcoat bobbin and needle handle joint portion; Extract in the sleeve pipe behind the pin can be from sleeve pipe outside the needle handle medicine-pouring port injectable drug of pin, this has just effectively overcome umbilical cord, and very smooth syringe needle is difficult for fixed defective puncturing successfully afterwards.
According to the disposable umbilical vein trocar that technique scheme is processed, cheap, use simply, safe and reliable, be convenient to promote.
Description of drawings
Below in conjunction with accompanying drawing and embodiment, the architectural feature of this utility model is further specified.
Fig. 1 is the structural representation of this utility model.
In the accompanying drawing, the 1. outer pin of sleeve pipe, 2. pin in the sleeve pipe, the 3. outer pin needle handle of sleeve pipe, 4. groove, the 5. outer needle body of sleeve pipe, 6. needle body in the sleeve pipe, 7. needle body is terminal in the sleeve pipe, and 8. the outer needle body of sleeve pipe is terminal.
The specific embodiment
Referring to Fig. 1, the said disposable umbilical vein trocar of this utility model is made up of pin 2 in the outer pin 1 of sleeve pipe, the sleeve pipe, and needle body 6 usefulness metals are processed and inserted in the outer needle body 5 of sleeve pipe in the sleeve pipe, and the end 7 of needle body and the outer needle body 8 of sleeve pipe is terminal concordant in the sleeve pipe.
The outer needle body 5 usefulness non-toxic plastics of said sleeve pipe are processed, and there is a ring-like groove 4 joint portion of needle body and needle handle sleeve pipe outside, and sleeve pipe needle body 5 outward has certain toughness.
