Detailed Description

The present invention will be further explained with reference to the accompanying drawings:

as shown in fig. 1, a needle tip separating device, comprising a hollow containing body 10,

the upper end surface of the accommodating body 10 is provided with a sliding opening 40, and the inner diameter of the sliding opening 40 is smaller than the outer diameter of the tail end of the needle head;

the side wall of the accommodating body 10 is longitudinally provided with a needle inlet 20, the upper end of the needle inlet 20 is a wide part 21, the lower end is a narrow part 22, and the inner diameter of the wide part 21 is larger than that of the narrow part 22;

the inner diameter of the wide part 21 of the needle inlet 20 is larger than that of the sliding port 40;

the outer end of the sliding port 40 is connected with the upper end of the needle inlet 20;

during use, as in fig. 1, the needle cylinder is placed longitudinally and then slid in the direction of the sliding port 40; the tail part of the needle head penetrates through the wide part 21, the needle tube part penetrates through the narrow part 22, the syringe body is positioned outside the accommodating body 10, and when the needle head enters the accommodating body 10 from the needle inlet 20, the syringe body is pulled upwards;

since the outer diameter of the tail of the needle is larger than the inner diameter of the sliding opening 40, the needle cannot pass through the sliding opening 40 and is left in the accommodating body 10, and the separation operation is realized.

An anti-skid layer is arranged on the inner bottom surface of the accommodating body 10; as shown in fig. 4, when the anti-slip layer is arranged, the needle point can be positioned after the needle head falls down in the drawing B, so that the disorder of the needle head is avoided to a certain extent, and the positions of the needle head can be adjusted as in the drawing A after the accommodating body is laterally placed, so that the needle heads can be regularly arranged; when the anti-slip layer is not provided, as shown in fig. C, the needle tip can move freely in the accommodating body 10, so that the needle bodies can cross freely, and the arrangement is disordered.

As shown in fig. 1-3, the needle inlet 20 and the baffle needle inlet 31 are obliquely arranged, so that when the needle head is adjusted on the side of the accommodating body, the needle body is not easy to leak from the needle inlet 20.

In one embodiment, the container 10 is provided with a cover 50; the cover 50 includes a first cover sheet 52 and a second cover sheet 53 perpendicular to each other;

the first cover sheet 52 slides on the upper end face of the containing body 10, and the second cover sheet 53 slides on the side face of the containing body 10.

Wherein the first cover plate 52 is rotated by means of the rotating member 51; the rotation member 51 is located at the middle of the upper end surface of the accommodating body 10.

Referring to fig. 1 and 2, the cover 50 is rotated by the rotating member 51, the first cover sheet 52 covers the sliding opening 40, and the second cover sheet 53 covers the needle inlet 20.

In another embodiment, a baffle 30 is arranged in the accommodating body 10, and the baffle 30 is located inside the needle inlet 20;

a baffle needle inlet 31 is formed in the upper part of the baffle 30; the inner diameter of the upper end of the baffle needle inlet 31 is larger than that of the lower part.

The sliding port 40 is arc-shaped; the end of the needle inlet 31 of the baffle is matched and connected with the sliding port 40, and a plurality of baffles 30 are arranged in sequence.

In use, as shown in FIG. 3, the needle is passed sequentially through needle inlet 20 and barrier needle inlet 31 along slide port 40 and the syringe body is pulled upward to effect the separation operation.

After separation, the baffle 30 plays a role of blocking, and can prevent the needle head from leaking from the needle inlet 20; the needle inlet 20 and the baffle needle inlet 31 are arranged along an arc, particularly the upper end parts of the needle inlet 20 and the baffle needle inlet 31 are arranged along an arc sliding port, and the common plane of the needle inlet 20 and the baffle needle inlet 31 is not vertical to the outer wall of the accommodating body 10;

when the baffle 30 is not provided, the receiving body 10 falls and the needle easily leaks out of the width.

The number of the baffle plates 30 is multiple, the baffle plate needle inlets 31 are arranged along the sliding port 40, and in combination with fig. 6, the baffle plate needle inlets 31 are on an arc surface, so that an inner needle body cannot pass through the baffle plate needle inlets 31 along an arc track.

The distance between the baffle needle inlet 31 and the needle inlet 20 is greater than the length of the needle body, so that even if the needle body can pass through the baffle needle inlet 31 of the baffle, the needle point of the needle body cannot reach the needle inlet 20, and the needle head is always positioned in the accommodating body 10.

With reference to fig. 4, the thickness of the sidewall of the sliding port 40 increases from the outside to the inside; when the barrel moves from the outside to the inside, the side wall of the sliding port 40 is sandwiched between the needle tail and the barrel, and as the thickness of the side wall of the sliding port 40 increases, the barrel and the needle tail increase in distance and are more easily separated.

The upper cover of the receiving body 10 increases in thickness from the edge to the middle.

A sucking disc is arranged on the lower end face of the accommodating body 10; the fixing device can be well adsorbed and fixed, and the falling risk of the fixing device is reduced.

It will be apparent to those skilled in the art that various modifications may be made to the above embodiments without departing from the general spirit and concept of the invention. Which all fall within the protection scope of the utility model. The protection scheme of the utility model is based on the appended claims.
