Description

Technical Field

[0001] This utility model relates to the field of partial improvement design technology of automatic preparation equipment for injectable drugs, and in particular to an automatic feeding device for syringes. Background Technology

[0002] In clinical medicine, intravenous infusion is often used as a treatment method to deliver medications, nutritional solutions, and other fluids into the patient's body to aid recovery. When patients require intravenous infusion, it is often necessary to mix and prepare various intravenous medications according to their condition. By using a syringe to draw and inject different intravenous medications, a solution can be prepared that better meets the prescription and treatment requirements.

[0003] Currently, the most common method is to manually prepare intravenous medications using syringes. However, this manual approach is inefficient, labor-intensive, and many medications have biochemical hazards. Given the current shortage of medical personnel in healthcare institutions, manual methods are insufficient for efficiently preparing large volumes of intravenous fluids. While some automated dispensing equipment exists that can automatically deliver syringes to the drug preparation unit, the syringe loading and delivery structures are complex and have relatively low reliability.

[0004] In the prior art, patent CN117706103A discloses a transport system for a suction device, which includes a loading device for loading the suction device, a picking device for picking up the suction device from a conveying mechanism to a target position, a calibration device having a calibration area for calibrating the position of the suction device, and a driving device. The loading device includes a feed channel having an inlet and an outlet for the suction device to move, a feeding mechanism adjacent to the outlet, and a cap removal mechanism. The feeding mechanism is configured to receive the suction device delivered from the outlet and transport the suction device to the feeding position. The cap removal mechanism is adjacent to the feeding position. The picking device includes a movable carrying mechanism, a clamping mechanism for holding the suction device, and a pushing mechanism for pushing the core rod. According to the suction device transport system of this disclosure, the suction device can be automatically transported, capped, and suctioned, and the accuracy of automated suction can be improved.

[0005] The above technical solution has a relatively complex overall structure and occupies a large space.

[0006] In order to solve one of the above problems, this application provides an automatic feeding device for syringes. Utility Model Content

[0036] Example 1

[0037] Reference Figure 1-9As shown, this utility model discloses an automatic syringe feeding device, which is used to provide syringes 3 to automated drug dispensing equipment. The syringe 3 is a commonly used and mature component, and its structure will not be described in detail here. The automatic feeding device of this application includes a storage device 1, which includes a storage tank 10 and a storage mechanism 11 and a transfer mechanism 12 located within the storage tank 10. The storage mechanism 11 carries and conveys a plurality of arranged syringes 3. The transfer mechanism 12 includes a first gripper 1204 that can move in three-dimensional space and clamp the syringes 3. The feeding device 2 includes a housing 20 and a conveying mechanism 213 and a discharging mechanism 214 located within the housing 20. Both sides of the housing 20 have movable openings, one of which is connected to the storage tank 10. The conveying mechanism 213 cooperates with the first gripper 1204 to carry and convey a plurality of arranged syringes 3. The discharging mechanism 214 includes a second gripper 2147 that can move in the horizontal direction. The second gripper 2147 clamps the syringes 3 and feeds them out through another movable opening of the housing 20, that is, provides syringes 3 to the automated dispensing equipment.

[0038] The storage tank 10 is a sealed box, one side of which can be opened to allow manual or automatic feeding of materials onto the storage mechanism 11. One side of the storage tank 10 is open and connected to the housing 20 so that the first gripper 1204 can deliver the syringe 3 to the conveying mechanism 213. The storage tank 10 is also equipped with a control panel, which communicates with and controls the operation of various motors, electric cylinders, and associated sensors. The structure and built-in program of the control panel are a mature modular design and will not be described in detail here. The housing 20 acts as a seal, with movable openings on both sides that can open and close during feeding and discharging. This ensures a clean environment inside the feeding device 2, providing a pre-contamination clean environment for subsequent equipment.

[0039] Example 2

[0040] Reference Figure 1-9As shown, based on the technical solution of Embodiment 1, an automatic syringe feeding device, as can be seen from 2-5, has several storage mechanisms 11 inside the storage tank 10. If multiple layers are provided, multiple storage mechanisms 11 are arranged side-by-side on each layer. Specifically, each storage mechanism 11 includes two parallel-operating first circular belts 114 and several syringes 3 arranged between them. The two horizontally parallel first circular belts 114 can clamp and forward-feed the syringes 3. Furthermore, the first circular belts 114 are driven by multiple first driven wheels 115 and first driving wheels 113. The first driven wheels 115 are mounted on a first support frame 111, which is fixed to a first support plate 110. The first driving wheels 113 are driven by a first motor 112 at reduced speed, and both are mounted on the first support plate 110, which is located inside the storage tank 10. The reduction mechanism of the first motor 112 is a conventional component and will not be described in detail here. Furthermore, as... Figure 4 As shown, the first support frame 111 is provided with a first feed clamping plate group 1112 and a first buffer clamping plate group 1111 at both ends, respectively. The upper surfaces of the two plates of the first feed clamping plate group 1112 are inclined to facilitate the syringe 3 to slide down onto the first circular belt 114 under its own weight. The upper surfaces of the two plates of the first buffer clamping plate group 1111 are flat and the height is slightly lower than the horizontal height of the upper end of the first circular belt 114. The side of the plate is machined with notches to facilitate the clamping operation of the first gripper 1204.

[0041] like Figure 6-7As shown, the transfer mechanism 12 includes a lifting assembly 122, a horizontal moving assembly 121 is mounted on the lifting assembly 122, a transfer assembly 120 is fixed on the horizontal moving assembly 121, the transfer assembly 120 includes a mounting base 1200, a rotating disk 1201 is provided inside the mounting base 1200, and a first gripper 1204 that can move linearly and perform clamping operations is provided on the rotating disk 1201. Specifically, both the lifting assembly 122 and the horizontal moving assembly 121 are displacement mechanisms driven by a motor after speed reduction. Generally, a conventional lead screw mechanism is selected, which will not be elaborated here. The rotary disk 1201 is driven by a rotary motor after speed reduction. The rotary motor is fixed in the mounting base 1200. The rotary disk 1201 is provided with a first horizontal displacement element 1202, which is an electric cylinder or electric push rod that can convert rotational motion into linear motion, which will not be elaborated here. The output end of the first horizontal displacement element 1202 is equipped with a first clamping element 1203, which is an electric gripper that can convert rotational motion into clamping action, which will not be elaborated here. The first clamping element 1203 is provided with a first gripper 1204. The lifting assembly 122 drives the horizontal moving assembly 121 to move up and down as a whole to match the syringes 3 on each layer of the storage mechanism 11. The horizontal moving assembly 121 drives the transfer assembly 120 to move linearly in the Y-axis direction to match the syringes 3 on each layer of the storage mechanism 11. The horizontal moving assembly 121 drives the first gripper 1204 to rotate and move linearly to adjust the angle to approach and clamp the syringes 3 on each storage mechanism 11 and extend into the feeding device 2 to drop the material.

[0042] Example 3

[0043] Reference Figure 1-9 As shown, based on the technical solution of the above embodiment, an automatic feeding device for syringes, as can be seen from 6-9, includes a conveying mechanism 213 comprising two parallel working second circular belts and a plurality of syringes 3 arranged between them; the second circular belts are driven by a plurality of second driven wheels and a second driving wheel 2132, the second driven wheels are mounted on a second support frame 2133, the second support frame 2133 is fixed on a base plate 210, the second driving wheel 2132 is driven by a second motor 2131 at reduced speed and both are mounted on the base plate 210; the two ends of the second support frame 2133 are respectively provided with a second feeding clamping plate group 31331 and a second buffer clamping plate group for clamping syringes 3, and the second buffer clamping plate group is provided with elastic grippers 2134. The structure of the conveying mechanism 213 is similar to that of the storage mechanism 11. The second buffer plate group is provided with elastic grippers 2134. The function of the elastic grippers 2134 is to stably hold the syringe 3 at the end of the conveying mechanism 213, so as to prevent the syringe 3 from being accidentally squeezed out of the second buffer plate group when the second circular belt is working.

[0044] like Figure 8 and Figure 9 As shown, the discharge mechanism 214 includes a limiting plate 2140 fixed on the base plate 210. A first shifting element and a sliding seat 2142 are installed on the limiting plate 2140. The first shifting element is a first electric cylinder 2141, which is a mature component that converts the rotational motion of a motor into linear motion. Its structural design will not be described in detail here. The function of the first shifting element is to drive the sliding seat 2142 to move linearly. Specifically, the limiting plate 2140 is provided with a linear guide rail. The sliding seat 2142 is installed on a slider that is slidably set on the linear guide rail. The bottom of the sliding seat 2142 is provided with a connecting rod 2143. Specifically, one end of the connecting rod 2143 is provided with a roller. The roller is movably set in the limiting groove 21400 of the limiting plate 2140. The other end of the connecting rod 2143 is connected to a rotating shaft 2144 that passes through the sliding seat 2142. The rotating shaft 2144 is provided with a second gripper 2147 that can move linearly and perform clamping operations. The limiting groove 21400 consists of two staggered straight grooves and an inclined groove connecting them. The roller rotates within the limiting groove 21400 and moves along its path. One end of the connecting rod 2143 is fixed to the bottom of the rotating shaft 2144, and the rotating shaft 2144 and the sliding seat 2142 are connected by a bearing assembly. A rotatable roller is mounted on the bottom of the other end of the connecting rod 2143. The rotation of the rotating shaft 2144 is driven by the rotation of the connecting rod 2143, which in turn is driven by the movement of the roller within the limiting groove 21400. This is achieved by the sliding seat 2142 driven by the first shifting element. In actual operation, the conveying mechanism 213 and the other movable opening of the outward feeding housing 20 are set opposite each other and their heights match. The syringe 3 needs to be clamped and rotated 180 degrees horizontally before being fed outward. That is, the linear reciprocating motion of the sliding seat 2142 drives the connecting rod 2143 to move and makes the rotating shaft 2144 perform a semi-circular rotation. The corresponding second gripper 2147 also rotates the clamped syringe 3 180 degrees and feeds it outward to the other movable opening of the housing 20.

[0045] Furthermore, the rotating shaft 2144 is provided with a second shifting element, which is a second electric cylinder 2145. A second clamping element 2146 is installed at its output end, and a second gripper 2147 is provided on the second clamping element 2146. Since the height of the second gripper 2147 is flush with the height of the elastic gripper 2134, the second gripper 2147 does not need to adjust its own height. The rotating shaft 2144 drives the second electric cylinder 2145 to perform a semi-circular rotation to match the syringe 3 held by the elastic gripper 2134 on the conveying mechanism 213 and the other movable opening of the outward-feeding housing 20. The rotating shaft 2144 and the second electric cylinder 2145 cooperate to drive the second gripper 2147 to rotate and linearly feed, adjusting its angle to approach the syringe 3 held by the elastic gripper 2134 and extend it outward from the other movable opening of the housing 20 for feeding.

[0046] Combination Figure 1 and Figure 8 As can be seen, the housing 20 includes a bottom plate 210 and a top plate 217. The bottom plate 210 has a return air hole, and a fan filter unit 216 is provided below the top plate 217. The fan filter unit 216 is a conventional component and will not be described in detail here. The housing 20 has a built-in high-efficiency fan filter unit 216 with a self-cleaning function, which is conducive to maintaining the cleanliness of the core area. The gas inside the housing 20 returns to the air inlet of the fan filter unit 216 through the return air hole of the bottom plate 210 and the ventilation hole of the side wall interlayer. After filtration, it forms clean new gas that enters the housing 20, ensuring the cleanliness of the inside of the housing 20 and providing a pre-clean environment for subsequent equipment. The movable openings on both sides of the housing 20 include a first side opening plate 211 and a first baffle 212, as well as a second side opening plate and a second baffle 215. The first baffle 212 moves in the X and Y axes via a first planar displacement component 2120 to block or move away from the first side opening plate 211. The second baffle 215 moves in the X and Y axes via a second planar displacement component 2150 to block or move away from the second side opening plate. The first baffle 212 and the second baffle 215 open and close alternately and cannot open simultaneously, thereby ensuring a clean environment for each machine. The first planar displacement component 2120 and the second planar displacement component 2150 mentioned above are two electric cylinders stacked in the horizontal and vertical directions. Specifically, the horizontal electric cylinder causes the vertical electric cylinder to move linearly in the X-axis direction, and the vertical electric cylinder causes the first baffle 212 or the second baffle 215 to move linearly in the Y-axis direction, so that the baffle and the side opening plate can be opened or closed smoothly. To ensure the sealing effect of the baffle, a sealing ring can also be added to the baffle or the side opening plate.

[0047] In this utility model device, the assembly and coordination of the various components, such as the electric cylinder, the fan filter unit 216, the motor or motor, the control panel and its supporting control software, are existing technologies or materials. The relevant technical personnel can directly purchase or order them from the market according to the required product model and specifications.

[0048] All electrical components mentioned in the text are connected to an external main controller and 220V AC mains power or industrial power. The main controller can be a conventional known device such as a computer that plays a control role.

[0049] The above description is merely a preferred embodiment of this utility model, and common knowledge regarding specific structures and characteristics is not described in detail here. It is obvious to those skilled in the art that this utility model is not limited to the details of the above embodiments, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model. Therefore, the embodiments should be considered exemplary and non-limiting in all respects. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the protection scope of this utility model.
