Description

Syringe needle hub separation device

[0001] The present invention relates to a syringe needle separation device, and more specifically, to a device that separates a needle hub and a syringe body from each other by inserting a portion where the syringe and the needle hub are joined to each other into a groove of a needle hub separation portion and rotating the syringe.

[0002] A syringe may include a needle connected to a needle hub, a connection portion of a syringe body to which the needle hub is connected, and a cap connected to the needle hub and enclosing the needle. After the cap connected to the needle hub is connected to the connection portion of the syringe body, the syringe is used after the cap is removed. Accordingly, the needle connected to the needle hub is used by being fitted into the connection portion of the syringe body.

[0003] For safety and environmental reasons, the used syringes are disposed of separately by separating the needle and syringe body connected to the needle hub.

[0004] In a disposable syringe, there are two methods for separating the needle from the syringe body: manually separating the needle from the needle hub, or cutting the needle hub or the connecting portion with a knife. Manual separation poses a risk of the user being pricked by a contaminated needle. Meanwhile, cutting the needle hub with a knife requires frequent blade replacement.

[0005] Therefore, a syringe needle detachment device that operates automatically while maintaining stability and providing user convenience is required.

[0006] The technical problem to be solved by the present invention is to provide a syringe needle hub separation device that separates the needle hub from the syringe body by inserting the needle hub into the groove of the needle hub separation part and then rotating the syringe insertion barrel into which the syringe is inserted.

[0046] These are the operational state diagrams showing the separation operation of the body.

[0047] A Luer Slip type syringe is connected to a needle hub by a friction fit. The present invention can stably and automatically separate the needle hub and the syringe body by relative rotation of the needle hub separation unit and the syringe body in a needle hub inserted into a groove of the needle hub separation unit.

[0048] For automatic needle hub separation, a syringe detection sensor equipped with an infrared light source and an infrared detection sensor is used. The syringe detection sensor confirms the insertion of a syringe into the syringe insertion barrel, and the rotation drive unit automatically rotates the syringe insertion barrel to separate the needle hub from the syringe body. Subsequently, the rotation drive unit further rotates the syringe insertion barrel by approximately 120 degrees so that the needle hub and syringe body can be stored in separate collection containers.

The syringe insertion tube may include a first recessed portion, in which a portion of the lower side wall of the outer tube is recessed, to provide rotation of approximately 120 degrees. Furthermore, for a compact structure, the syringe insertion tube may include a second recessed portion facing the first recessed portion. The second recessed portion may provide smooth rotation of the syringe insertion tube without contacting other structures, such as a housing or base, when the syringe insertion tube rotates.

[0050] The syringe insertion barrel may include a hemispherical lower cover at the bottom of the inner barrel. The lower cover has a lower through hole at its center, and the connecting portion of the syringe body and the needle hub may be exposed to the outside by passing through the lower through hole. The lower cover may be separated from the inner barrel, allowing for easy cleaning or replacement.

[0060] Referring to FIGS. 4 to 6, a syringe needle hub separation device (100) includes a syringe insertion barrel (120) having a cylindrical hole (123) therein and into which a syringe (10) is inserted; a rotational driving unit (160) that rotates the syringe insertion barrel (120) about a rotational axis (169) in a horizontal direction (y-axis direction) at a lower end of the syringe insertion barrel (120); a base (130) to which the rotational driving unit (160) is fixed; and a needle hub separation unit (140) that is fixed to the base (130) at the lower end of the syringe insertion barrel (120) and includes a groove (142) that is inserted between a needle hub (12, needle hub) of the syringe and a connecting portion (10a) of the syringe to which the needle hub (12) is coupled. As the syringe insertion tube (120) rotates around the rotation axis (169), the groove (142) of the needle hub separation part (142) is inserted between the needle hub (12) and the connection part (10a), thereby separating the needle hub (12) and the connection part (10a) from each other.

[0061] The above syringe insertion tube (120) has an outer tube (121) and an inner tube (122), and the outer tube (121) and the inner tube (122) are connected to each other at the upper end. The inner tube (122) may have a portion whose diameter decreases as it progresses from the upper end to the lower end.

[0062] The inner cylinder (122) may include a lower cover (124) having a lower through hole (124a) through which the needle hub (12) and the connecting portion (10a) of the syringe pass. The lower cover (124) has a hemispherical shell shape and may have a curved shape in a cross-sectional view.
