Embodiment Construction

[0043] Preferred embodiments of the needle protection device of the present invention and a safety needle assembly including the needle protection device will be described in detail below with reference to the accompanying drawings.

[0044] figure 1 Shown is a safety needle assembly according to the invention in a packaged state before use. The needle safety assembly includes a needle 10 , a needle protector and a protective cap 16 .

[0045] The needle head 10 includes a needle hub 12 and a needle 11 mounted on the needle hub 12 . The needle 10 is also called an "injection needle" when it is used for a syringe or the like, and the needle 11 is also called a "needle tube". The present invention is not intended to improve the needle 10 itself. Therefore, various needles known in the art that need to be protected after use can be used to construct the safety needle assembly of the present invention. The safety needle assembly of the present invention may be, but not limited ...

Abstract

The invention discloses a needle head protection device and a safety needle component comprising the needle head protection device. The needle head protection device comprises a connection part and a protection arm which can rotate relative to the connection part, wherein a pair of clamping members are formed on a near end part of the protection arm and the connection part respectively and can bejoined in a non-withdrawal mode; and a pair of positioning arms are formed on the near end part of the protection arm and the connection part respectively, at least one pair of complementary clampingcharacteristics are formed, and the paired clamping characteristics can be joined in a detachable mode. According to the needle head protection device and the safety needle component provided by the invention, puncture accidents caused by needle heads after use of medical instruments of a syringe and the like can be reliably prevented, the type of medical instruments can only be used once, and a simple structure and low cost are realized. Besides, the needle head protection device can be stably positioned at each desired position during transportation and use of the safety needle component.

Description

technical field [0001] The invention relates to a needle protection device, in particular to a needle protection device capable of preventing accidental stabbing of needles used in medical instruments such as syringes and blood collection devices after use. The invention also relates to a safety needle assembly comprising such a needle protection device. Background technique [0002] In medical practice, medical devices with sharp needles are widely used, such as syringes, blood collection devices and the like. These medical devices are not only used and handled by professionals in medical institutions, but also often used and handled by non-professionals at home, such as self-injection of insulin by diabetic patients. [0003] Because the needles of medical instruments such as syringes are exposed outside after use, it is easy to stab the relevant personnel, which causes great difficulties in collection and processing. Such puncture wounds can also cause infection with ge...
