Abstract
The invention relates to a medical syringe. The medical syringe comprises a core rod, a piston and a cylinder. An opening used for connecting the core rod is formed in one end of the cylinder, and a conical head used for connecting a needle is arranged at the other end of the cylinder. One end of the core rod is fixedly connected with the piston and is movably inserted into the cylinder. The outer diameter of the piston is the same as the inner diameter of the cylinder. A housing fixed to one end of the cylinder is arranged on the circumferential side of the conical head. A core rod head sleeve used for protecting the conical head is arranged in the housing. A connection groove matched with the core rod head sleeve is formed in the other end of the core rod. The core rod and the core rod head sleeve are connected through the connection groove, and the function of driving the core rod to move is achieved. A clamping groove used for storing the needle is formed in the surface of the cylinder. The medical syringe has the advantages of being simple in structure, convenient to use, capable of improving the use safety and effectively protecting the conical head and the needle, and the like.
Description
Technical field
The present invention relates to technical field of medical instruments, particularly injector for medical purpose.
Background technology
Syringe is a kind of utensil conventional in medical apparatus and instruments, although it is simple, a little easy to use to have structure, its shortcoming is also very outstanding.Its maximum shortcoming is: manufacturing enterprise in process of production with medical personnel before not using, generally find that this syringe conehead ruptures, the product of fracture cannot use, and easily causes syringe needle contaminated, occur malpractice; The syringe of prior art is all that syringe separates with syringe needle and deposits, and careless slightlyly in transportation syringe needle will be done loose, may have damage; Will abandon with the syringe crossed, the syringe in the front in removal process of the syringe needle after using may drop, and to recovery, personnel damage.
Summary of the invention
For the problems referred to above, the object of this invention is to provide a kind of structure simple, easy to use, improve safety in utilization, the injector for medical purpose of energy available protecting conehead and syringe needle.
Realize technical scheme of the present invention as follows:
Injector for medical purpose, 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, 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, the all sides of described conehead are provided with the sheath body being fixed on cylindrical shell one end, the core bar headgear for the protection of conehead is provided with in sheath body, the other end of core bar is provided with the link slot adapted with core bar headgear, core bar and core bar headgear are connected by link slot and have the function driving core bar movement, described drum surface is provided with the draw-in groove for storing syringe needle.
One end of described core bar headgear is provided with the protector adapted with conehead, and the other end is provided with gripper shoe, and advantage is that conehead is placed in protector, can effectively protect conehead not to be damaged.
Described core bar headgear and sheath body, core bar are threaded connection, and core bar headgear outer surface is provided with external screw thread, the inwall of sheath body and link slot has the female thread adapted with external screw thread, and advantage is connected firmly, easy to use.
Described draw-in groove inwall and bottom are provided with aseptic cotton, and advantage is the needle sterilizing before realizing contact patient skin, also can protect syringe needle in addition, prevent syringe needle from damaging in draw-in groove.
Described draw-in groove is provided with seal cover, and seal cover is T-shaped structure, and advantage is can effectively coordinate with draw-in groove, thus the closed cavity of formation one is protected syringe needle, prevents contaminated.
Have employed above-mentioned scheme, when not using, core bar headgear is connected with sheath body, and core bar headgear is by conehead seal protection, prevent it from surprisingly rupturing or cylindrical shell contaminated to scrap, increase unnecessary cost, syringe needle is placed in draw-in groove, effectively can prevent syringe needle from doing loose, so that damage; During use, take off core bar headgear, be contained on core bar, syringe needle is taken out in draw-in groove, be arranged on conehead, now can carry out dynamic core bar and absorb medicinal liquid and inject, so just can effectively work, sheath body also has the degree of depth that can control inserting needle when injecting in addition, alleviates the work difficulty of medical worker; After use, take off syringe needle like this and plough under in draw-in groove, do not need syringe needle to separate with syringe to deposit, and easy accessibility, greatly can facilitate the use of doctor, take off core bar headgear and be arranged on conehead, the same with when not using conehead to be protected.
