Example 1

The present embodiment provides a needle-stick prevention device, as shown in fig. 1, which comprises a head 10 and a handle 20 connected to the head 10, wherein the head 10 is provided with a needle-stick prevention region for wrapping a needle, and the handle 20 is arranged on a side of the head 10 far away from the needle-stick prevention region.

In use, after the nurse pulls the needle, the handle 20 is held by the hand, the needle is inserted into the puncture-proof area of the head 10, and the needle is discarded into a sharp box.

Example 2

This example provides a needlestick prevention device, as shown in fig. 2, which is substantially the same as example 1, and the main differences are: the head 10 further comprises a base 11, and the handle 20 is connected to the head 10 via the base 11. The use of a hard material for the base 11 prevents the needle from penetrating the puncture-proof area, thereby avoiding a protective failure and preventing a puncture of the fingers of the user holding the handle portion 20.

The support bottom 11 can be arranged only at the bottom of the head 10 and is adhered with the head 10; the base 11 can also be a half-wrapped structure, so that the head 10 is wrapped in the base, when the needle penetrates into the puncture-proof area at an angle, the needle may penetrate through the side surface of the head 10, and therefore, the half-wrapped base 11 structure can better prevent the needle from penetrating into the puncture-proof area and then injuring the human body.

Example 3

This example provides a needlestick prevention device that is substantially the same as either example 1 or example 2, with the main differences being: the head 10 is a hollow structure, and the stab-resistant area is arranged on the surface of the head 10. The hollow head part 10 reduces the material consumption without influencing the function of protecting the needle head, thereby further reducing the cost.

The shape of the head 10 may be any shape, generally square, but if a hollow structure is used, the shape of the head 10 is preferably circular, which is beneficial to reducing the manufacturing cost and overcoming the defect that the hollow structure is easy to collapse. For a round head 10, if a collet is used, the collet may be configured as a half-pack, the bottom center of the collet being connected to the handle 20 to facilitate support of the head 10 by the handle 20, the round head 10 not being easily disconnected from the handle 20 when in use.

Example 4

The handle part 20 has a certain length, the handle part 20 occupies a certain space when the anti-acupuncture device is put into a sharp air box for recovery after use, and the handle part 20 of the anti-acupuncture device after use is broken by the breaking groove 21, so that the space of the sharp machine box can be saved, and resources are saved; the broken handle 20 is individually dropped into a yellow trash bag.

Since only the breaking groove 21 is formed in the handle portion 20, the handle portion 20 is made of a material that is easily bendable, such as: wood, rigid plastic, rubber, and the like. If the support base 11 is provided on the anti-needle-stick device, the support base 11 and the handle 20 may be integrally or fixedly connected. The position of the break-off slot 21 needs to be close to the head 10 so as to minimise the footprint of the anti-needle stick device for retrieval into the sharps container after use. The shank 20 may be provided with a cylindrical shape, which facilitates breaking.

Example 5

This example provides a needlestick prevention device substantially the same as any of examples 1 to 4, the main differences being: the head 10 is detachably connected to the handle 20. If the head 10 is directly connected with the handle 20, the head and the handle are detachably connected; if the head 10 is connected with the handle 20 through the support base 11, the head 10 is fixedly connected with the support base 11, and the support base 11 is detachably connected with the handle 20.

Further, as shown in fig. 3 and 4, a threaded hole 12 is formed in the head 10, and an end of the shank 20 to which the head 10 is coupled is threaded corresponding to the threaded hole 12. The breaking groove 21 may be difficult to break or needs a large force when the handle 20 is broken due to its short length, and the handle 20 is difficult to break if made of metal material, so that the head 10 and the handle 20 are connected by a screw connection, so that the handle 20 can be separated by rotating the handle 20 after use without breaking the handle 20.

If the head 10 is connected with the handle 20 through the support bottom 11, the support bottom 11 is provided with an avoidance hole so that the threaded end of the handle 20 is in threaded connection with the threaded hole 12 of the head 10; alternatively, the holder 11 is provided with a threaded hole 12 to be screwed with the shank 20. The latter connection method results in a slightly longer anti-needle punch device than the former connection method.

Further, as shown in fig. 5 and 6, the handle 20 is provided with a locking groove 22, and the head 10 is provided with a locking protrusion 13 corresponding to the locking groove. Besides the threaded connection mode, the clamping mode can also overcome the defect of the folding groove.

If the head 10 is connected with the handle 20 through the support bottom 11, the support bottom 11 is provided with an avoiding hole, and the clamping protrusion 13 of the head 10 passes through the avoiding groove to be clamped with the clamping groove 22 of the handle 20; or, the support base 11 is provided with a clamping protrusion 13 for clamping with the clamping groove 22 of the handle 20, and the head 10 is fixedly connected with the support base 11.
