Referring to fig. 1, the present utility model provides a sharps container 10 and sharps container cover 100. The sharpener barrel 10 includes a sharpening barrel cover 100 and a barrel body 200.

The barrel 200 is hollow and can accommodate medical waste such as a needle of an infusion tube, and the outer contour of the barrel can be cylindrical, inverted truncated cone-shaped, and the like. One end of the tub 200 is opened, and the sharps container cover 100 covers the opened end of the tub 200. The sharps cover 100 is generally removably attached to the tub 200. Specifically, the sharpener cover 100 may be mounted to the barrel 200 by a threaded engagement, a snap-fit, or the like. In addition, the sharps container 10 generally further includes a self-sealing cover (not shown), which can cover the outer periphery of the sharps container cover 100 when the sharps container 10 is not in use, so as to protect the sharps container cover 100 and provide a better sealing effect for the container body 200.

Referring to fig. 2 and 3, the sharpening barrel cover 100 according to the preferred embodiment of the present utility model includes a cover 110, a cutting blade 120 and a turntable 130.

The contour of the cover 110 matches the contour of the opening of the tub 200. The cover 110 includes a top wall (not shown) and a side wall (not shown) disposed around a circumference of the top wall. In particular, in this embodiment, the top wall is circular, so the side wall is circular. Obviously, the top wall may also be adjusted according to the shape of the opening of the tub 200. The sidewall may be provided with a screw thread, a buckle, etc. for mounting the cover 110 at the opening of the tub 200. When the cover 110 is disposed at the opening of the tub 200, the surface of the top wall facing the inside of the tub 200 is referred to as a back surface, and the surface of the top wall facing away from the inside of the tub 200 is referred to as a front surface. The material of the cover 110 is generally the same as that of the tub 200, and may be plastic.

Further, the top wall of the cover 110 is provided with an operation hole 101 and a guide groove 102, and the guide groove 102 is communicated with the operation hole 101. The operation hole 101 and the guide groove 102 penetrate the top wall in the thickness direction. Moreover, the opening range of the operation hole 101 is large, and the infusion tube can extend into the tub 200 from the operation hole 101.

The cutting blade 120 is fixedly disposed on the back surface of the top wall of the cover 110, and the cutting blade 120 is located within the guide groove 102. That is, the front projection of the cutting blade 120 on the rear side of the top wall at least partially overlaps the guide slot 102. Also, the cutting edge of the cutting blade 120 faces one side of the operation hole 101. The cutting blade 120 may be secured to the back of the top wall of the cover 110 by various means such as bonding, screw fastening, etc.

The turntable 130 is mounted to the back of the top wall. Moreover, the turntable 130 is rotatable about an axis perpendicular to the top wall. The turntable 130 may be directly mounted to the top wall of the cover 110 through screws and a rotating shaft, or may be indirectly mounted to the top wall of the cover 110 through other structures. In this embodiment, the top wall and the turntable 130 are circular, and the turntable 130 is disposed coaxially with the top wall.

In addition, a clamping groove 131 is formed at the edge of the turntable 130. The end of the clamping groove 131 far from the center of the turntable 130 is provided with an outward opening so as to facilitate the placement of the infusion tube in the clamping groove 131. Further, as the dial 130 rotates, the locking groove 131 can sequentially pass under the operation hole 101 and the guide groove 102, and at least part of the locking groove 131 can overlap with the cutting blade 120 within the guide groove 102. That is, when the card slot 131 passes under the guide slot 102, the front projection of the card slot 131 on the back of the top wall at least partially overlaps with the front projection of the cutting blade 120 on the back of the top wall.

When the sharp instrument barrel 10 is used for collecting the needle of the infusion tube, the end of the infusion tube with the needle is firstly extended into the barrel body 200 through the operation hole 101, and the infusion tube is placed in the clamping groove 131. The operator then applies force to the infusion tube and rotates the dial 130 (clockwise in fig. 2). As the catch 131 passes under the guide slot 102, the infusion tube will follow the catch 131 into the guide slot 102 and continue to move along the guide slot 102 until it contacts the cutting blade 120. A scissor-like structure is formed between the turntable 130 and the cutting blade 120, the infusion tube is cut off by the inertia of the turntable 130, and the end of the infusion tube with the needle falls into the barrel 200 to collect the needle. In this process, the operator only needs to put the infusion tube into the clamping groove 131 and drive the turntable 130 to rotate, so that the operation can be performed by one hand.

The guide slot 102 may extend in a straight line or in an arc. In particular, in the present embodiment, the guide groove 102 has a circular arc shape, and the guide groove 102 extends along the circumferential direction of the turntable 130. Further, the circle in which the guide groove 102 is located is disposed concentrically with the top wall of the cover 110. When the turntable 130 rotates around the axis, the infusion tube in the clamping groove 131 also moves along the circular arc track. Therefore, the guide groove 102 is arranged in a circular arc shape, so that the infusion tube can conveniently enter the guide groove 102, and the infusion tube can be ensured to move smoothly along the guide groove 102.

More specifically, in the present embodiment, the extending direction of the edge of the cutting blade 120 is inclined with respect to the radial direction of the guide groove 102. In this way, a gradually narrowing slit can be formed between the edge of the cutting blade 120 and the inner wall of the guide groove 102, the slit having a wider open end. When the infusion tube moves along the guide groove 102 along with the clamping groove 131, the infusion tube can enter from the opening end of the slit and be gradually clamped, so that the resistance when the cutting blade 120 cuts the infusion tube can be reduced.

In the present embodiment, a plurality of clamping grooves 131 are formed on the edge of the turntable 130, and the plurality of clamping grooves 131 are equally spaced along the circumference of the turntable 130. It can be seen that no matter the turntable 130 rotates to any angle, the clamping groove 131 can be ensured to exist below the operation hole 101, so that the angle of the turntable 130 does not need to be adjusted when the next infusion tube is cut.

In the present embodiment, the width of the card slot 131 gradually decreases in the outside-in direction. That is, the width of the opening of the slot 131 is larger, and the width of the bottom of the slot 131 is smaller. The wider opening facilitates placement of the infusion tube to be cut into the card slot 131. In addition, because the width of the bottom of the clamping groove 131 is smaller, when the rotary disc 130 and the cutting blade 120 are matched to cut off the infusion tube, a gap formed between the inner wall of the clamping groove 131 and the inner wall of the guide groove 102 is smaller, so that the cut needle head is prevented from jumping out of the gap.

In this embodiment, a stopper 140 is disposed on the back of the top wall of the cover 110, the stopper 140 is provided with a avoidance slot (not shown) for avoiding the guide slot 102, and the turntable 130 is rotatably mounted on the stopper 140. The limiting block 140 can be a metal block or a plastic block, and has a certain thickness. When the sharpening barrel cover 100 is assembled, the cutter blade 120 is fixed on the back of the top wall, the rotary disk 130 is rotatably mounted on one side of the limiting block 140, and finally one side of the limiting block 140 facing away from the rotary disk 130 is attached to the back of the top wall and fixed. The limiting block 140 can be fixed with the back surface of the top wall in a bonding mode, a threaded fastening mode and the like.

The needle of the infusion tube is close to the hard plastic piece at the tail end of the hose, and the width of the clearance groove on the limiting block 140 is smaller than the width of the plastic piece. When the end of the infusion tube with the needle is extended into the barrel 200, the height of the plastic piece is smaller than the height of the lower surface of the limiting block 140, so that the plastic piece is positioned below the limiting block 140 after the infusion tube enters the guide groove 102 along with the clamping groove 131. When the infusion tube contacts the cutting blade 120, the infusion tube is pulled downwards to be tightened, and the position-avoiding groove can limit the plastic part, so that the needle is prevented from withdrawing upwards from the position-avoiding groove, and the cutting position of the infusion tube is ensured to be positioned at the hose.

In addition, the infusion tube enters the guide groove 102 along with the clamping groove 131 and enters the avoidance groove of the guide groove 102. When the remaining space in the tub 200 is small (generally, set to one third of the total capacity), the movable space in the tub 200 becomes very small and the cutting operation for the infusion tube becomes difficult because the needle itself has a certain length and the stopper 140 occupies a certain height in the tub 200. At this time, the operator can determine that the barrel 200 is full, and thus, even if the operation is stopped, the operator can prevent the sharps container 10 from overflowing due to excessive needle collection.

Further, in the present embodiment, the extending direction of the clearance groove coincides with the extending direction of the guide groove 102. It can be seen that the clearance groove in this embodiment is also circular arc.

When the sharpening barrel cover 100 and the sharpening barrel 10 are used, one end of the infusion tube with the needle head can be stretched into the barrel body 200 through the operation hole 101, the infusion tube is placed in the clamping groove 131, and the rotary table 130 can be driven to rotate by applying acting force to the infusion tube. As the dial 130 rotates, the infusion tube will follow the catch 131 into the guide slot 102 and move along the guide slot 102 until it contacts the cutting blade 120, so that the infusion tube can be cut off under the combined action of the dial 130 and the cutting blade 120, and the end of the infusion tube with the needle falls into the barrel 200. Therefore, when the sharp instrument barrel 10 is used for collecting the infusion tube needle, an operator only needs to put the infusion tube into the clamping groove 131 and drive the turntable 130 to rotate, so that the operation can be performed by one hand, and the operation efficiency is obviously improved.

The technical features of the above-described embodiments may be arbitrarily combined, and all possible combinations of the technical features in the above-described embodiments are not described for brevity of description, however, as long as there is no contradiction between the combinations of the technical features, they should be considered as the scope of the description.

The above examples illustrate only a few embodiments of the utility model, which are described in detail and are not to be construed as limiting the scope of the utility model. It should be noted that it will be apparent to those skilled in the art that several variations and modifications can be made without departing from the spirit of the utility model, which are all within the scope of the utility model. Accordingly, the scope of protection of the present utility model is to be determined by the appended claims.
