Abstract

(57) Abstract: To provide a protective socket for an injection cylinder that effectively reduces the probability of accidentally sticking a hand. SOLUTION: A protective socket of an injection cylinder A has a long cylindrical body 1.
0, and has a storage space of a predetermined depth along the longitudinal direction of the shaft for inserting the tip of the needle of the syringe barrel A. The cylindrical body 10 has a protective disc 20 having an appropriate height and thickness and formed in an annular shape on the outer circumference. When the user grips the protective socket with the fingers of the hand, the fingers can be shielded behind the protective disc 20, so that the needle is biased by the enlarged protective surface without properly inserting the tip of the needle into the accommodation space.

[Technical field to which the invention belongs]

 BACKGROUND OF THE INVENTION Field of the Invention The present invention relates to a medical device, and more particularly, to an improved structure for preventing a medical worker from accidentally sticking a hand when inserting a tip of a syringe barrel into a protective socket.

[0002]

[Prior art]

 As is well known, it can be said that it is a common practice for medical staff to inject a drug solution into a patient with a syringe to fix the illness. However, statistics show that when a medical employee inserts the tip of a needle into a protective socket (commonly known as the “dual needle”), he often punctures the finger of his hand with the needle and hepatitis, AIDS or other illnesses are caused by the patient's blood. May lead to

[0003]

[Problems to be solved by the device]

 The common name “turning needle” mentioned above is a state in which the tip of the needle of the syringe barrel is put into the protective socket after the medical staff has taken the patient's blood or injected the liquid medicine. At this time, it is easy to accidentally pierce the finger of the hand with the injection needle. This is because common protective sockets have a smooth and long conical shape, and when time is too tight, the tip of the needle will slip out of the protective socket entrance due to carelessness and temporary visual error. Because I stab my finger.

Therefore, medical personnel may have no choice but to operate with one hand or purchase another base to reduce the likelihood of accidentally sticking a finger. However, since such a method or tool is very inconvenient for the actual situation, the medical practice of holding a protective socket with one hand and grasping a syringe with one hand and handling a commonly known needle is still common today.

In view of this, the present inventor finally designed the present invention as a result of research and improvement based on his experience of selling medical devices. A main object of the present invention is to provide a protective socket for a syringe barrel that effectively reduces the probability of accidental hand sticking.

[0006]

[Means for Solving the Problems]

 In order to achieve the above objects, the protective socket of the syringe barrel provided by the present invention has a long tubular body and has a predetermined depth along the longitudinal direction of the shaft for inserting the needle tip of the syringe barrel. There is a storage space for Sasa. Further, a ring-shaped protective disc having an appropriate height and thickness is installed on the outer circumference of the cylindrical body. Thus, when the user grips the protective socket with the finger of the hand, the finger can be shielded behind the protective disc against the needle of the syringe barrel. Therefore, even if the tip of the needle is not properly inserted into the accommodation space, the biased tip of the needle is blocked by the enlarged protective surface, so that accidental pricking of the hand can be avoided.

[Embodiment of the invention]

 Hereinafter, embodiments of the present invention will be described with reference to the drawings. The protective socket of the syringe barrel shown in FIGS. 1, 2 and 3 is a protective product for inserting the tip of the needle of the syringe barrel, and avoids piercing the human body by exposing the tip of the needle. As shown in FIGS. 4 and 5, the syringe barrel A is almost the same as the one currently used and is not within the scope of the invention, so its explanation is omitted.

The protective socket of the injection barrel A has a long cone-shaped cylindrical body 10, and the outer diameter of the cylindrical body 10 gradually shrinks from one end of the mouth opening toward the inside, so that the opening diameter is large. It is a long socket with a small inner diameter. Further, an annular rib 11 is provided at the center of the outer peripheral edge of the tubular body 10 to improve the frictional force with which the user grips the tubular body 10. In other words, when the tubular body 10 is gripped, it becomes more stable, firm and non-slip.

As shown in FIGS. 1, 2 and 3, a plurality of convex portions 12 are provided on the inner peripheral edge at one end of the opening of the tubular body 10, and the head A 1 at the end of the injection barrel A is attached to the tubular body. When entering 10, it has a tightening effect. The most important point is to install the protective disc 20 between the tip of the annular rib 11 and the opening of the tubular body 10. The protective disc 20 is formed in an annular shape and has an appropriate height and thickness from the radial direction of the tubular body 10 to the outside. Since its height is almost the same as the thickness of the fingers of the human body, the fingers can be shielded behind the protective disc 20. In this embodiment, the protective disc 20 is formed on the outer side of the tubular body 10 as in the case of integral molding, but of course, it is included in the same category even if it is arranged by a tightening method or another separation method. To be considered

In summary, according to the present invention, an annular protective disc is installed on the outer periphery of the cylindrical body, and provides a larger protective cross-sectional area as shown in FIG. That is, if the same area is enlarged, the fingers of the user's hand can be shielded thereafter. Then, even if the tip of the needle is not correctly inserted into the receiving space, the stabbed area is where the protective disk is and protects the fingers of the hand. After all, the structural design effectively avoids the phenomenon of medical workers stabbing their hands in the so-called “turning hand” state when time is too near.
