Description

Technical Field

[0001] This utility model relates to the field of improved design technology of auxiliary equipment for post-dispensing drug processing, and in particular to a syringe processing device after liquid preparation. Background Technology

[0002] Disposable medical syringes, once used, are treated as medical waste and require centralized recycling. During recycling, the needle must be separated from the syringe barrel, and the needle and barrel must be processed separately. Currently, there is a lack of specialized syringe separation devices on the market. Medical staff typically cut off the needle with scissors or separate the needle by hand, then place the needle and barrel into appropriate containers. Hospitals use a large number of disposable syringes daily, and separating the needles in this way is time-consuming and labor-intensive, and exposes operators to serious occupational exposure risks. Even a slight mistake could result in needlestick injuries and infection with bloodborne pathogens.

[0003] In the prior art, patent CN109621098B discloses an automatic syringe needle and syringe barrel separation and recovery device. This device has a needle clamping and separating mechanism in the middle of the frame, a syringe barrel clamping mechanism on the upper part of the frame, and a needle collection box and a syringe barrel collection box on the lower part of the frame. The operator only needs to place the syringe needle-downward into the tray of the syringe positioning mechanism. The syringe barrel clamping mechanism automatically clamps the syringe barrel, while the needle clamping and separating mechanism automatically clamps and rotates the needle, separating the syringe barrel and needle. Then, the needle clamping and separating mechanism releases, allowing the needle to fall automatically into the needle collection box, while the syringe barrel is held above the syringe barrel collection box by the syringe barrel clamping mechanism before being released, allowing the syringe barrel to fall automatically into the syringe barrel collection box. This device is ingeniously designed, highly automated, easy to operate, and widely applicable, suitable for various syringes with needles inserted into or threaded onto the syringe barrel interface.

[0004] Patent CN209475289U discloses a needle removal device. This device is suitable for removing needles from an aspirator and includes: a fixed plate; a rotating cylinder disposed on the fixed plate, adapted to accommodate at least one part of the needle and to drive the needle to rotate, thereby detaching it from the aspirator; and a drive assembly adapted to drive the rotating cylinder to rotate. This needle removal device can automatically remove needles from an aspirator and place them into a needle collection container.

[0005] In order to solve one of the above problems, this application provides a syringe processing device after liquid preparation. Utility Model Content

[0033] Example 1

[0034] Reference Figure 1-7 As shown, this utility model discloses a syringe processing device after liquid preparation, including a cutting and dispensing mechanism 1 mounted on a support plate 42. The cutting and dispensing mechanism 1 includes a limiting component, a cutting component 13, and a dispensing component 19. The limiting component supports and positions the syringe 3, completing the action of clamping and fixing the syringe barrel. The cutting component 13 is located on the side of the limiting component and is used to cut off the end of the syringe barrel, separating the needle from the syringe barrel. The needle falls directly and is collected, while the syringe barrel remains clamped and fixed. The dispensing component 19 is located at the bottom of the limiting component and is used to tilt the syringe barrel of the syringe 3 after cutting, allowing it to dispense at an angle. The syringe 3 is a commonly used and mature component, assembled from a syringe barrel and a needle through a plug-in or threaded connection; its specific structure will not be described in detail here. This device can be used independently, with manual placement of syringe 3 for semi-automatic operation, or it can be installed outside the main unit of the automatic liquid preparation equipment, away from the core preparation area, which is beneficial for the protection of the dust-free environment and the safety of the medicines. It adopts an automatic feeding method to achieve the automated operation of the whole machine.

[0035] Example 2

[0036] Reference Figure 1-7 As shown, based on the technical solution of Embodiment 1, a syringe processing device after liquid preparation, regarding the specific structural design of the limiting component, is as follows: Figure 4-7It is known that the limiting component includes a support plate 151, a fixed cutter 150 and a baffle 153. The support plate 151 is provided with an opening groove for accommodating the syringe 3. The fixed cutter 150 and the baffle 153 are respectively arranged at both ends of the opening groove. The opening groove is a through-type U-shaped groove structure, which is convenient for accommodating the syringe. At the same time, both ends of the syringe 3 can be limited and locked and released. Furthermore, the bearing plate 151 is rotatably mounted on the horizontal plate 11, which is fixed to the support plate 42 by the vertical plate 10, thus meeting the design requirements for inclined material discharge. The fixed cutter 150 is fixed on the side plate 12, which is mounted on the horizontal plate 11. The baffle 153 is connected to the first electric actuator 152, which can achieve linear reciprocating motion of the baffle 153. That is, when the baffle 153 is close to the bearing plate 151, it can limit the syringe 3 placed in the opening slot. Conversely, when the baffle 153 is away from the bearing plate 151, the opening slot can tilt the material discharge. The first electric actuator 152 is mounted on the horizontal plate 11. The vertical plate 10 and the side plate 12 are vertical plates, while the horizontal plate 11 and the support plate 42 are horizontally fixed plates. Furthermore, the fixed cutter 150 has an L-shaped structure, and the fixed cutter 150 supports and blocks the end of the syringe connected to the needle. The first electric actuator 152 is located on the side of the support plate 151 and drives the baffle 153 to move linearly.

[0037] Example 3

[0038] Reference Figure 1-7 As shown, based on the technical solution of the above embodiments, a syringe processing device after liquid preparation, regarding the specific structural design of the cutting component 13, is as follows: Figure 4-7 It is understood that the cutting component 13 includes a movable cutter 132 and a driving member. The driving member drives the movable cutter 132 to reciprocate linearly, and the direction of movement of the movable cutter 132 is perpendicular to the axial direction of the syringe 3. It can cut at the junction of the needle tip and the syringe barrel to make the needle tip drop.

[0039] Furthermore, the driving component includes a motor 130, which is equipped with a reducer. The reducer is an existing component and will not be described in detail here. A first roller 135 is eccentrically mounted on the output shaft 131 of the motor 130 after speed reduction. The first roller 135 is movably mounted in the vertical groove of the moving plate 134. To reduce wear, the first roller 135 is rolled within the vertical groove. The first roller 135, whose position on the output shaft 131 is offset from the shaft core, combined with the vertical groove, is similar to a cam mechanism. This converts the rotational motion of the output shaft 131 into the linear reciprocating motion of the moving plate 134. The moving plate 134 is fixed on the sliding plate 133, and a movable cutter 132 is mounted on the sliding plate 133. Thus, the movable cutter 132 has the function of linear reciprocating motion. In addition, the motor 130 is mounted on the side plate 12, and the side plate 12 is fixed on the horizontal plate 11; the sliding plate 133 is fixed on the slider 137, the slider 137 is slidably mounted on the linear guide rail 136, the linear guide rail 136 is mounted on the horizontal plate 11, and the horizontal plate 11 is fixed on the support plate 42 by the vertical plate 10. The combination of the linear guide rail 136 and the slider 137 can provide support and guidance for the sliding plate 133.

[0040] Example 4

[0041] Reference Figure 1-7 As shown, based on the technical solution of the above embodiments, a syringe processing device after liquid preparation, regarding the specific structural design of the material feeding component 19, is as follows: Figure 6 and Figure 7 It is known that the feeding assembly 19 includes a rotatable support plate 151. The syringe 3 is placed on the opening slot of the support plate 151 and tilted by the lifting component. The lifting component includes a second electric actuator 191 fixed on the vertical plate 10. The second electric actuator 191 drives the support plate 151 to rotate, causing the opening slot to tilt, thereby causing the syringe 3 to slide down.

[0042] Furthermore, the bearing plate 151 is mounted on the horizontal plate 11 via a bearing 195. A convex plate is fixed on the horizontal plate 11, and the convex plate and the bearing plate 151 are connected by a hole-shaft fit via the bearing 195. The horizontal plate 11 is fixed on the support plate 42 via a vertical plate 10. A limiting groove 194 is machined on the bearing plate 151. The limiting groove 194 is generally machined in the horizontal direction. A second roller 193 is movably installed in the limiting groove 194. To reduce wear, the second roller 193 is rolled within the limiting groove 194. The second roller 193 is mounted on a top rod 192. The top rod 192 is provided with two fork plates to connect the two ends of the second roller 193. The top rod 192 is connected to a second electric actuator 191 for lifting and lowering movement. The second electric actuator 191 is fixed on the vertical plate 10. The two electric actuators are generally electric cylinders, which are common components on the market and will not be described in detail here. The feeding assembly 19 is similar to a lever mechanism. The second electric actuator 191 drives the top rod 192 to rise and fall, causing the second roller 193 to rise and fall within the limiting groove 194. This causes the bearing plate 151 to rotate around the bearing 195 and tilt downwards, so that the syringe in the opening groove is fed under the action of gravity.

The bottom of the box body 43 is provided with casters 44 with brakes. The box body 43 is provided with a first collection box and a second collection box corresponding to the first discharge channel 51 and the second discharge channel 52, respectively. The first collection box is used to collect the needles that fall in, and the second collection box is used to collect the syringes that fall in. The upper box cover 41 is provided with a feeding channel 2. The outlet of the feeding channel 2 is located above the support plate 151 of the limiting component.
