[0036] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is in no way intended to limit the present invention and its application or use. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0037] like Figures 1 to 3As shown, an embodiment of the present invention provides a medical sharps collection device, which includes a sharps box 10, a fixed knife part 20, a movable knife part 30 and a shielding part 40. The sharps box 10 has a accommodating cavity 101 and a delivery port 102 connected to the accommodating cavity 101, and the delivery port 102 is arranged at the top of the sharps box 10; the fixed knife part 20 is fixedly arranged on the sharps box 10, and the fixed knife part 20 has a first blade 201, and at least part of the projection of the first blade 201 is located in the delivery port 102; the movable knife part 30 is arranged opposite to the fixed knife part 20, and the movable knife part 30 is movably arranged on the sharps box 10, and the movable knife part 30 is close to or away from the first blade 201. The movable knife part 30 has a second blade 301, and the second blade 301 is located on the side of the movable knife part 30 close to the fixed knife part 20, and the second blade 301 cooperates with the first blade 201 to cut the infusion tube; the shielding part 40 is movably arranged on the sharps box 10, and the shielding part 40 is used to shield or open at least part of the delivery port 102.

[0038] By applying the technical solution of the present invention, when it is necessary to recover the needle of the infusion set, the shielding portion 40 is opened, the needle is placed into the accommodating chamber 101 through the delivery port 102, and the infusion set is moved between the movable blade portion 30 and the fixed blade portion 20. The movable blade portion 30 is driven so that the movable blade portion 30 is close to the fixed blade portion 20, and the movable blade portion 30 and the fixed blade portion 20 cooperate to cut the infusion tube, and the needle falls into the accommodating chamber, completing the recovery of the needle. The above arrangement enables the needle to always be located in the accommodating chamber 101 when the staff cuts the infusion tube, thereby avoiding the possibility of the needle falling outside the sharps box 10 and reducing the possibility of drug residues splashing outside the sharps box 10. Moreover, the shielding portion 40 shields at least a portion of the delivery port 102 during non-recovery operations, thereby preventing aerosols containing drug residues from escaping from the delivery port 102 due to improper operation or unexpected situations as much as possible, thereby reducing environmental pollution; and by shielding the delivery port 102, dust and other pollutants can be prevented from entering the accommodating chamber 101, thereby maintaining the cleanliness and hygiene of the interior of the accommodating chamber.

[0039] like Figures 1 to 5As shown, the medical sharps collection device further includes a transmission portion 50, which is arranged between the shielding portion 40 and the movable blade portion 30. The movable blade portion 30 drives the shielding portion 40 through the transmission portion 50 to block or open at least a portion of the delivery port 102; when the movable blade portion 30 is in a first extreme position, the shielding portion 40 blocks the delivery port 102; when the movable blade portion 30 is in an intermediate position, the shielding portion 40 completely opens the delivery port 102; when the shielding portion 40 moves from the intermediate position to a second extreme position, the delivery port 102 is in an open state, and the second blade 301 cooperates with the first blade 201 to cut the infusion tube. When the movable blade portion 30 is in different extreme positions, the transmission portion 50 can drive the shielding portion 40 to achieve three different states, namely, completely blocking the delivery port 102, completely opening the delivery port 102, and after the delivery port 102 is fully opened, the second blade 301 and the first blade 201 cut the infusion tube. During the movement of the movable knife part 30, the position of the shielding part 40 is adjusted by the transmission part 50, so that the injection port 102 can be blocked or opened, thereby improving the operational flexibility and controllability of the medical sharps collection device.

[0040] Specifically, when the movable blade portion 30 is in the middle position, the shielding portion 40 fully opens the insertion port 102 through the action of the transmission portion 50, allowing medical personnel to quickly and conveniently insert used medical sharps, thereby optimizing the operating process. After the infusion tube is placed between the fixed blade portion 20 and the movable blade portion 30, the movable blade portion 30 continues to move toward the fixed blade portion 20 to cut the infusion tube.

[0041] It can be understood that when the movable blade part 30 is at the first limit position, the distance between it and the fixed blade part 20 is the farthest.

[0042] In an embodiment of the present solution, the moving direction of the movable knife portion 30 is at an angle to the extending direction of the first blade 201. The first end 401 of the shielding portion 40 is rotatably disposed on the sharps box 10, and the second end 402 of the shielding portion 40 swings around the first end 401 to shield or open at least a portion of the delivery port 102. In an embodiment of the present solution, the moving direction of the movable knife portion 30 is perpendicular to the extending direction of the second blade 301.

[0043] Furthermore, the delivery port 102 includes a first opening section, which is arc-shaped. The contour of at least a portion of the shielding portion 40 matches the contour of the first opening section. The movable blade portion 30 is located at one end of the first opening section, and the fixed blade portion 20 is positioned adjacent to the movable blade portion 30. When the shielding portion 40 blocks the first opening section, the two ends of the shielding portion 40 are located on either side of the moving direction of the movable blade portion 30. Specifically, the first end of the shielding portion 40 is located on one side of the moving direction of the movable blade portion 30, and the second end of the shielding portion 40 is located on the other side of the moving direction of the movable blade portion 30. This arrangement enables the shielding portion 40 to precisely control its position through the movable blade portion 30, achieving flexible opening and closing of the delivery port 102. Furthermore, by setting the movable blade portion 30 in three different positions, the state of the shielding portion 40 can be switched to accommodate different usage requirements.

[0044] Specifically, the transmission portion 50 includes a first tooth-shaped structure 51 and a second tooth-shaped structure 52 that mesh with each other. The first tooth-shaped structure 51 is provided on the movable blade portion 30, and the extension direction of the first tooth-shaped structure 51 is the same as the movement direction of the movable blade portion 30; the second tooth-shaped structure 52 is provided on the first end 401 of the shielding portion 40, and the second tooth-shaped structure 52 is located on the outer periphery of the rotating shaft of the first end 401 of the shielding portion 40, and extends along the circumference of the rotating shaft. Through the meshing of the first tooth-shaped structure 51 and the second tooth-shaped structure 52, the power transmission process from the movable blade portion 30 to the shielding portion 40 is simplified, and additional transmission components are reduced, making the operation easier and faster. In addition, the design of the tooth-shaped structure generally has high mechanical strength and stability, and can withstand long-term repeated use, thereby improving the durability and reliability of the entire transmission portion 50.

[0045] In an embodiment of the present scheme, the first tooth-shaped structure 51 is arranged on the side wall of the movable knife portion 30 at one end close to the shielding portion 40, and a circular connecting block 41 is provided at the bottom of the shielding portion 40. The circular connecting block 41 is coaxial with the rotating axis of the first end of the shielding portion 40, and the second tooth-shaped structure 52 is arranged on the side wall of the circular connecting block 41 along the circumference of the circular connecting block 41.

[0046] Furthermore, the sharps collection device also includes an escape portion, in which the movable blade portion 30 is movably disposed. When the movable blade portion 30 is in the escape position, the second blade 301 is located in the escape portion. When the movable blade portion 30 is in the cutting position, the second blade 301 is located in the delivery port 102. The existence of the escape portion provides a safe escape space for the movable blade portion 30. When the movable blade portion 30 is not in operation, the second blade 301 is hidden in the escape portion, effectively avoiding safety accidents caused by accidental contact with the blade.

[0047] Specifically, the avoidance portion includes an avoidance groove 1031 and an avoidance hole 1032 that are interconnected. The avoidance groove 1031 is provided on the side wall of the delivery port 102, and the avoidance hole 1032 is provided on the top surface of the sharps box 10. The movable knife portion 30 includes a main body portion 31 and a grip portion 32 that are connected to each other. The second blade 301 is provided on the main body portion 31, and the main body portion 31 is movably provided in the avoidance groove 1031. The grip portion 32 is movably provided in the avoidance hole 1032. When the movable knife portion 30 is in the avoidance position, the second blade 301 is accommodated in the avoidance groove 1031. When the position of the movable knife portion 30 needs to be changed, the staff can adjust the position of the movable knife portion 30 by operating the grip portion 32.

[0048] Furthermore, in this embodiment, a mounting groove 104 is also provided on the top surface of the sharps box 10. The mounting groove 104 is located at the bottom position of the first end of the shielding portion 40 and is connected to the avoidance groove 1031. The circular connecting block 41 is rotatably arranged in the mounting groove 104 so that the second tooth-shaped structure 52 and the first tooth-shaped structure 51 engage with each other.

[0049] Furthermore, the delivery port 102 includes a first side wall 1021 and a second side wall 1022 connected to each other, with an angle formed between the first side wall 1021 and the second side wall 1022. The fixed blade portion 20 is disposed on the first side wall 1021, with the first blade 201 facing the second side wall 1022, and the avoidance groove 1031 is disposed on the second side wall 1022. The angle between the first side wall 1021 and the second side wall 1022 provides a stable fixing point for the infusion tube, facilitating precise positioning of the infusion tube during the cutting process, thereby improving the accuracy and efficiency of the cutting. Furthermore, once the infusion tube is fixed within the angle, it can directly contact the first blade 201, ensuring the accuracy and consistency of the cutting position.

[0050] Furthermore, the medical sharps collection device further includes a reset portion 60, the two ends of which are connected to the movable blade portion 30 and the sharps box 10, respectively. The reset portion 60 is used to apply a force to the movable blade portion 30 toward the end away from the fixed blade portion 20. By applying a stable force, the reset portion 60 ensures that the movable blade portion 30 is fixed in the initial position when not in operation, thereby improving the overall stability of the device.

[0051] Specifically, in this solution, the reset part 60 includes a reset spring, the extension and contraction direction of the reset spring is the same as the moving direction of the movable knife part 30, the reset spring is located in the avoidance groove 1031, one end of the reset spring is connected to the end of the movable knife part 30 away from the second blade 301, and the other end is connected to the end of the avoidance groove 1031 away from the delivery port 102.

[0052] Furthermore, the delivery port 102 includes an interconnected infusion needle delivery port 1023 and an infusion tube movable port 1024. The cross-sectional area of ​​the infusion needle delivery port 1023 is larger than that of the infusion tube movable port 1024, and the projection of the first blade 201 is located within the end of the infusion tube movable port 1024 away from the infusion needle delivery port 1023. The larger cross-sectional area of ​​the infusion needle delivery port 1023 facilitates the rapid delivery of a used needle. The smaller cross-sectional area of ​​the infusion tube movable port 1024, and the location of the fixed blade portion 20 at the end of the infusion tube movable port 1024 away from the infusion needle delivery port 1023, can reduce the possibility of residual drug splashing and enhance the safety performance of the device.

[0053] In the embodiment of this solution, the contour of the shielding portion 40 is adapted to the contour of the infusion tube moving port 1024 .

[0054] In other embodiments of the present solution, the contour of the shielding portion 40 is adapted to the overall contour of the infusion set needle insertion port 1023 and the infusion tube moving port 1024 .

[0055] Furthermore, in this embodiment, a syringe needle insertion port 105 is provided at the top of the sharps container 10. In a cross section parallel to the top wall of the sharps container 10, the width of the syringe needle insertion port 105 gradually increases along its length, and both ends of the lengthwise direction of the syringe needle insertion port 105 are outwardly convex arc structures. This gradually increasing width design can accommodate syringe needles of different diameters, improving the versatility of the insertion port.

[0056] Furthermore, the present invention also includes a cover 70 that is hingedly mounted on the top of the sharps container 10. When closed, the cover 70 ensures the stability of the contents of the sharps container 10, making it easy to carry and transport, and suitable for use in various medical environments. Furthermore, when closed, it prevents drug residues or contaminants from escaping into the external environment.
