Description

Technical Field

[0001] The utility model relates to the technical field of sharps storage, in particular to a medical sharps storage box. Background Art

[0002] Sharps storage boxes are very common instruments in hospitals. After searching, it was found that the existing technology, such as the Chinese patent (application number: 202323532555.4), involves a medical sharps storage bucket. The needle is separated from the bottle body through the needle breaking port and then falls on the inclined surface. Under the action of gravity, the needle slides on the inclined surface and enters the left cavity from the needle tube entrance; the bottle body is directly put into the bottle injection port and falls into the right cavity of the barrel body through the bottle body entrance, completing the separation and collection of the needle body and the bottle body.

[0003] However, in the above patent, if the bottle-dropping port and the needle-breaking port are in use, and the barrel body is accidentally hit and overturned, the sharp objects inside can easily fall out from the bottle-dropping port and the needle-breaking port, causing pollution to the environment and possibly threatening human health and causing infection. Therefore, improvements are needed. Utility Model Content

[0005] In order to achieve the above objectives, the present invention is implemented through the following technical solutions:

[0006] A medical sharps storage box includes a box body, a box cover threadedly installed at the box opening at the upper end of the box body, a circular mounting opening provided on the top of the box cover, an elastic sealing mechanism provided in the mounting opening to prevent sharp objects inside from falling out of the box body when the box body is overturned, the elastic sealing mechanism including a sealing piece, the vertical cross-section of the sealing piece being an isosceles trapezoid, the waist of the sealing piece resting on the lower part of the mounting opening, and the waist of the sealing piece being mounted on the box cover through two symmetrically arranged elastic structures.

[0007] Specifically in the present invention, the elastic structure includes a hole body vertically opened on the top of the box cover, a vertical guide rod is fixed to the top of the blocking piece, the upper end of the guide rod extends through the upper end of the hole body and is fixed with a blocking piece, a spring is arranged between the blocking piece and the box cover, and the spring is sleeved on the guide rod.

[0008] In order to facilitate the removal of the needle, the hole body is an arc-shaped hole, and the two hole bodies are arranged symmetrically on the box cover. A needle removal structure is provided between the box cover and the sealing piece. The needle removal structure includes an arc-shaped needle drop hole opened on the box cover, and an arrow-shaped needle entry hole is opened on the top of the sealing piece, and the needle entry hole is located below the arc-shaped needle drop hole.

[0009] Compared with the prior art, the utility model has the following beneficial effects: when the elastic blocking mechanism is in use, it can prevent internal sharp objects from falling out of the box body when the box body is overturned, thereby preventing environmental pollution and threats to human health. It has a simple structure and high practicality. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0018] like Figure 2 As shown, the utility model provides a medical sharps storage box, comprising a box body 1, a box cover 2 threadedly installed at the box opening at the upper end of the box body 1, a circular mounting opening provided on the top of the box cover 2, and an elastic blocking mechanism provided in the mounting opening to prevent the sharp objects inside from falling out of the box body 1 when the box body 1 is overturned, the elastic blocking mechanism comprising a blocking piece 3, the vertical cross-section of the blocking piece 3 is an isosceles trapezoidal arrangement, the waist of the blocking piece 3 is against the bottom of the mounting opening, and the waist of the blocking piece 3 is mounted on the box cover 2 through two symmetrically arranged elastic structures.

[0019] like Figure 2-3 As shown, in the utility model, the elastic structure includes a hole body 2-1 vertically opened on the top of the box cover 2, a vertical guide rod 4 is fixed to the top of the blocking piece 3, the upper end of the guide rod 4 extends through the upper end of the hole body 2-1 and is fixed with a blocking piece 5, a spring 6 is provided between the blocking piece 5 and the box cover 2, and the spring 6 is sleeved on the guide rod 4.

[0020] like Figure 2-6As shown, in order to facilitate the removal of the needle, the hole body 2-1 is an arc-shaped hole, and the two hole bodies 2-1 are arranged symmetrically on the box cover 2. A needle removal structure is provided between the box cover 2 and the blocking piece 3. The needle removal structure includes an arc-shaped needle drop hole 2-2 opened on the box cover 2, and an arrow-shaped needle entry hole 3-1 is opened on the top of the blocking piece 3. The needle entry hole 3-1 is located below the arc-shaped needle drop hole 2-2.

[0021] like Figure 4-5 As shown, the working principle of the present invention is described in detail below: when the needle needs to be placed in the box body 1, the guide rod 4 is pushed to move along the hole body 2-1, driving the blocking piece 3 to rotate, so that the needle hole 3-1 is located just above the arc-shaped needle drop hole 2-2, as shown in FIG. Figure 4 When the syringe is in the closed position, the needle tip is pulled up and the syringe is separated from the syringe and falls into the box body 1. When other sharp objects need to be placed in the box body 1, the blocking piece 3 is pressed down, and the blocking piece 3 moves down, driving the guide rod 4 and the blocking piece 5 to move down, squeezing the spring 6. At this time, there is a gap between the blocking piece 3 and the installation port, so that other sharp objects can fall into the box body 1 from the gap, and the waist of the blocking piece 3 can assist the sharp object to fall into the box body 1. Loosen the blocking piece 3, and the elastic force of the spring 6 will push the blocking piece 5 to move up, thereby driving the guide rod 4 and the blocking piece 3 to move up until the blocking piece 3 blocks the installation port. This can prevent the box body 1 from falling out of the installation port when it is accidentally bumped and overturned. When the box body 1 is not in use, the guide rod 4 can also be rotated to Figure 5 In this way, the needle hole 3-1 is no longer located directly above the arc-shaped needle drop hole 2-2, and the box cover 2 blocks the needle hole 3-1.

[0022] Finally, the most important contribution of the present invention is that the elastic sealing mechanism can prevent internal sharp objects from falling out of the box body 1 when the box body 1 is overturned, thereby preventing environmental pollution and threats to human health. It has a simple structure and high practicality.

[0023] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
