Description
Technical field
This utility model relates to technical field of medical instruments, particularly a kind of syringe.
Background technology
At present, syringe used clinically is formed primarily of needle tubing, needle tubing, piston and nook closing member, and this syringe is after giving patient injection, and its structure, function are still intact, are easy to again be recycled, serious threat human health.
Summary of the invention
For the problems referred to above, the purpose of this utility model is to provide a kind of use safety, can prevent by the syringe repeatedly recycled.
Realize the technical solution of the utility model as follows:
A kind of syringe, comprise core bar, piston and cylindrical shell, one end of cylindrical shell is set to the opening for connecting core bar, the other end is provided with the conehead for connecting needle tubing, conehead is connected with needle tubing, one end of core bar is fixedly connected with piston and is movably inserted in cylindrical shell, the external diameter of piston is consistent with the internal diameter of cylindrical shell, described needle tubing is arranged with the protecting cover for the protection of needle tubing, conehead outer surface is provided with the sleeve be fixed on cylindrical shell, cavity is formed between conehead and sleeve, one end of protecting cover is positioned at cavity and moveable and sleeve connection, described needle tubing and conehead are formed in one, cylindrical shell is provided with the support member of finger ring shape structure.
Described sleeve and protecting cover are set to be threaded, the end that sleeve is connected with protecting cover is provided with the first limited step, the protecting cover be positioned at outside sleeve is provided with the second limited step, advantage forms protecting cover mobile space between the first limited step and the second limited step, the distance of protecting cover movement is limited, protecting cover is moved around in sleeve, prevent protecting cover from moving long and departing from sleeve, when protecting cover props up the first limited step, needle tubing just closes by protecting cover completely, prevent needle tubing from exposing and stab people and accidental damage, when the second limited step props up sleeve, needle tubing just exposes, injection work can be carried out.
Described support member is provided with two, and advantage is applicable medical worker operation.
Have employed above-mentioned scheme, needle tubing is protected by protecting cover and conehead has sleeve to surround, and can effectively prevent it from surprisingly rupturing or contaminated, so that scraps, and increases unnecessary cost; Protecting cover moves around in sleeve, makes needle tubing expose use and closed protective, substantially increases safety in utilization; Again use is recovered in order to prevent the syringe after using, so conehead and needle tubing are supported one-body molded, prevent from other people from changing needle tubing to continue to use, when again protecting cover being moved to the position of closed needle tubing, be broken, due to the protection of protecting cover, so not dangerous to the person, this syringe is and scraps like this, cannot use, avoid and be used again; When injecting, all need to use the support member supporting finger, the support member of finger ring shape not only can be played a supporting role when injecting, and also can play a supporting role, not needing to change other action, greatly saving the time, improve work efficiency when extracting medicinal liquid.
