Detailed Description

The following description is made with reference to the accompanying drawings and a specific embodiment.

To make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the drawings of the embodiments of the present invention are combined to clearly and completely describe the technical solutions of the embodiments of the present invention, and obviously, the described embodiments are some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention. Thus, the following detailed description of the embodiments of the present invention, presented in the accompanying drawings, is not intended to limit the scope of the invention, as claimed, but is merely representative of selected embodiments of the invention.

It should be noted that: like reference numbers and letters refer to like items in the following figures, and thus, once an item is defined in one figure, it may not be further defined and explained in subsequent figures.

See fig. 1-6. The needle cap withdrawal and retraction device described in this embodiment includes a base 100, and when in use, the base 100 is placed on a table top, and in order to increase the friction force between the base 100 and the table top, a fixing member, including but not limited to a rubber pad, a suction cup or a magnet, may be selectively disposed at the bottom. Of course, the holder body 100 does not have to be provided with a fixing member.

The base body 100 is provided with an upwardly open slide plate mounting hole in which the slide plate 200 is slidably fitted. In this embodiment, the sliding plate mounting hole is provided with a guiding post 210, and correspondingly, the sliding plate is provided with a guiding hole in sliding fit with the guiding post 210, and the sliding plate 200 is in sliding fit with the guiding post 210. The axis of the guide post 210 is parallel to the longitudinal direction of the first notch 101.

The needle head baffle 110 and the needle cap baffle 120 are respectively arranged on two sides of the sliding plate 200, the first notch 101, the third notch 201 and the second notch 111 are sequentially arranged on the needle cap baffle 120, the sliding plate 200 and the needle head baffle 110, and the third notch 201 and the second notch 111 are all positioned on an extension line of the first notch 101. The first slot 101 is horizontally arranged along the length direction of the base 100. The first notch 101, the third notch 201 and the second notch 111 are grooves for placing a syringe needle and a needle cap. The first notch 101, the third notch 201 and the second notch 111 are of equal size, or the first notch 101, the third notch 201 are of equal size, the second notch is slightly smaller than the first notch 101. in a typical syringe used by medical personnel, the diameter of the pintle section is smaller than the diameter of the cap section, and flanges are provided on both the pintle and the cap. In order to adapt to the syringes with different specifications and sizes, the first notch is arranged to be a V-shaped groove, the second notch is arranged to be a V-shaped groove, and the third notch is also arranged to be a V-shaped groove. The V-shaped groove comprises at least one inclined surface, and can also be two inclined surfaces. The embodiment provides the case that the V-shaped groove is provided with two symmetrical inclined surfaces; of course, the V-shaped grooves can be arranged asymmetrically, and can also be arranged in a mode of one vertical surface and one inclined surface. The smaller the syringe needle cap is, the closer the needle cap is to the bottom of the V-shaped groove when the cap is taken; the larger the syringe needle cap is, the closer the needle cap is to the opening direction of the V-shaped groove when the cap is taken.

A cover plate (not shown) may be selectively installed at the opening of the first notch 101, and in this embodiment, no cover plate is installed at the opening of the first notch 101.

To facilitate sliding the sliding plate 200, the present embodiment is provided with a driving mechanism connected to the sliding plate; specifically, the driving mechanism includes a push rod 300 fastened to the slide plate.

The base 100 is provided with a blind hole 102, and the axial lead of the blind hole 102 is parallel to the length direction of the first notch 101. In the extending direction of the blind hole 102, a connecting hole connected with the push rod 300 is arranged on the sliding plate 200, a through hole for the push rod to pass through is arranged on the needle head baffle 110, the push rod 300 is in sliding fit with the blind hole 102 and the through hole, and a spring 302 is further arranged in the blind hole 102. The sliding plate 200 is tightly connected with the push rod 300, and by pushing or pulling the push rod 300, the sliding plate 200 moves therewith, i.e. the sliding plate 200 and the push rod 300 do not shift relatively during use. In this embodiment, the push rod 300 is connected to the connection hole through a screw.

In order to facilitate pushing the push rod 300 and improve the use comfort, an expansion part 301 is further arranged at the outer end of the push rod 300. That is, one end of the push rod 300 is in contact with the spring 302, and the other end of the push rod is provided with an enlarged portion 301.

Of course, the drive mechanism may be replaced in other ways than in the present embodiment.

When the needle cap is separated, the seat body 100 is placed on a table top, under the elastic pressure of the spring 302, the sliding plate 200 is attached to the needle baffle 110, the needle cap is placed horizontally to the first notch 101, the third notch 201 and the second notch 111, namely, the flange part of the needle bolt is positioned on the outer side surface of the needle baffle 110, the flange part of the needle cap is positioned between the sliding plate 200 and the needle cap baffle 120, the pushing is pushed, the expanding part 301 of the pushing plate 300, the sliding plate 200 moves towards the direction of the needle cap baffle 120, the needle cap is separated from the needle bolt under the action of the sliding plate 200, and the separated needle cap is placed horizontally in the first notch 101.

When the needle cap is sleeved back, the needle cylinder is horizontally placed, and the needle point passes through the second notch 111 and the third notch 201 and then is inserted into the needle cap. The needle cap can be sleeved back on the needle bolt by the counterforce of the bottom of the needle cap baffle 120 or the first notch 101 on the needle cylinder when the needle cap is inserted.

When the needle cap pillowcase is separated, the sliding distance of the sliding plate 200 does not need to be overlarge, the needle cap can be loosened by sliding about 2mm, and the needle cap can be separated from the pintle by sliding about 5 mm. The sum of the thicknesses of the needle baffle 110 and the sliding plate 200, particularly the sum of the thicknesses of the notches is smaller than the distance between the flange of the needle cap and the flange of the needle bolt when the needle cap is sleeved on the needle bolt, for example, in a certain brand of 5ml disposable syringe, the distance between the flange of the needle cap and the flange of the needle bolt is 4mm, and the needle cap is completely separated from the needle bolt when being pulled out for 4 mm. After the separation operation is completed, the slide plate 200 is returned to its engagement with the needle shield 110 by the action of the spring 302.

The utility model is suitable for common syringes, and the needle cap and the pintle all have flanges. The needle cap flange is an annular bulge at the opening of the needle cap, and the pintle flange is an annular bulge at the part (close to one end of the nipple) of the pintle of the needle head.
