Embodiment 1

[0029] A safety protection device for injection needles, such as figure 1 and image 3 As shown, it includes a sheath 1 and a needle hub 2, the needle hub 2 is connected to the rear end of the sheath 1, one end of the sheath 1 is open, and a pair of hooks 3 are arranged on the rear end wall of the sheath 1 (such as Figure 5 As shown), the connection between the needle base 2 and the sheath 1 is provided with an elastic positioning device 5 with a limit function.

[0030] Such as Figure 5 As shown, the hook 3 can be directly arranged on the opposite side walls of the sheath 1, and the wings 10 at the base of the injection needle are pressed into the lower part of the hook 3 by means of finger pressure. The length is greater than the outer edge boundary of the hook 3, which is enough to block it and prevent it from moving upwards. The wings of the injection needle are sandwiched between the front sheath and the folded needle seat at the rear; Pull out the sheath and complet...

Embodiment 2

[0039] A safety protection device for injection needles, such as figure 2 and 3 As shown, it includes a sheath 1 and a needle hub 2, the needle hub 2 is connected to the rear end of the sheath 1, one end of the sheath 1 is open, and a pair of hooks 3 are arranged on the rear end wall or the bottom of the sheath 1 ( like Figure 6 As shown), the needle base 2 and the sheath 1 are oppositely provided with a pair of engaging buckles 4, and the connection between the needle base 2 and the sheath 1 is provided with an elastic positioning device 5 with a limit function.

[0040] Such as Figure 6 As shown, the hook 3 is arranged on the bottom wall of the sheath 1, and the fin 10 at the base of the injection needle is pressed into the lower part of the hook 3 by finger pressure, and the elongation length of the two fins 10 is greater than that of the hook 3 At the border of the outer edge of the needle, enough to block it and prevent it from moving upwards, the wings of the injec...

Embodiment 3

[0050] Improvement on the basis of embodiment 1 or embodiment 2 structure, as Figure 8-10 As shown, the lower part of the hook 3 is provided with a component locking hook 11, and the corresponding locking hole 12 is provided on the wing 10. Once the needle hub wing 10 is pressed down into the lower part of the hook 3 in the protective cover, the locking hook 11 It is closely matched with the lock hole 12 to further prevent loosening due to external force.

Abstract

The invention discloses a safety protection device for an injection needle, and belongs to the technical field of medical instruments. One end of a sheath of the device is opened, a pair of clamping hooks is arranged on the rear end wall or the wall bottom of the sheath, a pair of buckled buckles is oppositely arranged on a needle base and the sheath, and an elastic positioning device with the limiting function is arranged at the connection position of the needle base and the sheath. The elastic positioning device is arranged and can assist a medical worker in clamping in the operation process, safety is ensured further, and when the medical worker handles abandoned syringe needles on a large scale, the operation efficiency is improved; a protection wall is arranged outside the buckles, the buckles can move in place conveniently due to the protection wall serving as a limiter when the syringe needles are abandoned, the buckles can be protected and prevented from loosening due to external force, barb-shaped protrusions can firmly compress and limit needle tubings in the safe sheath, and the limiting similarly has the further safety function.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a safety protection device for injection needles. Background technique [0002] According to relevant statistics, my country is the most common country for injection, transfusion and blood collection. A large number of used injection needles are discarded every year in hospitals and various medical institutions. In order to avoid environmental pollution and waste reutilization, professional institutions need to recycle used injection needles. In order to prevent accidental injury or secondary infection to relevant personnel during the recycling process, the health department urgently needs a simple, safe and reliable injection needle protection device. At present, it is suggested to use a syringe whose needle can be retracted into the liquid medicine cavity after use, but this type of syringe has a complicated structure and high cost, and it is difficult to ...
