Description

Technical Field

[0001] This utility model belongs to the field of filling pump installation technology, and specifically relates to an auxiliary tool for filling pump installation. Background Technology

[0002] Filling pumps are core fluid transport and precise dispensing equipment in the biopharmaceutical industry, directly related to the safety, efficacy, uniformity and compliance of drug production. They are mainly used in the entire process of biopharmaceutical production, from R&D pilot-scale and pilot-scale to commercial mass production, especially in stages with extremely high requirements for sterility, precision and stability.

[0003] Given the stringent requirements for environmental cleanliness and equipment contamination control in the filling process, the filling pump, as a key installation component, requires operators to wear gloves to touch its pump core during installation. Although this avoids contamination caused by direct contact between human hands and the pump core, the gloves may still carry impurities, microorganisms, etc., which may cause the pump core to fail to meet cleanliness standards and thus contaminate the medicines filled through the pump core. Utility Model Content

[0004] This utility model provides an auxiliary tool for installing a filling pump, which aims to solve the problem that existing methods of directly contacting the pump core while wearing gloves can easily cause contamination of the pump core.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is: to provide an auxiliary tool for installing a filling pump, comprising: main body; The second functional structure is located on one side of the main body. The second functional structure has two clamping parts arranged opposite to each other, which are used to clamp the pump core.

[0006] In one possible implementation, the main body has a first functional structure on the side opposite to the second functional structure, and the first functional structure has a functional hole.

[0007] In one possible implementation, the main body, the first functional structure, and the second functional structure are integrally formed.

[0008] In one possible implementation, the main body, the first functional structure, and the second functional structure are all made of polyetheretherketone (PEEK) material.

[0009] In one possible implementation, the first functional structure is a ring structure, the outer diameter of which is greater than the width of the main body in the left-right direction.

[0010] In one possible implementation, the two clamping portions and the main body enclose a semi-circular receiving cavity and an opening located on the side of the receiving cavity opposite to the first functional structure.

[0011] In one possible implementation, the width of the opening gradually increases along the direction away from the first functional structure.

[0012] In one possible implementation, the outer edge of the opening is rounded.

[0013] In one possible implementation, the two clamping parts are located on the left and right sides of the main body, respectively, and each clamping part has a recessed positioning groove on the side opposite to the other clamping part.

[0014] In one possible implementation, the outer surfaces of the main body, the first functional structure, and the second functional structure are provided with anti-slip textures.

[0015] Compared with existing technologies, the solution shown in this application, during the assembly of the filling pump, replaces the traditional method of directly grasping the pump core while wearing gloves. Instead, the pump core is fixed between two clamping parts on the second working structure, with the two clamping parts clamping the pump core. The pump core can be picked up and put down by holding the main body. After the pump core and pump head are assembled, the clamping parts and pump core can be separated by pulling the main body. The pump core is stably clamped by the two clamping parts, and the operator does not need to touch the pump core directly with their hands. This fundamentally avoids the problem of impurities and microbial contamination of the pump core by gloves, ensuring the cleanliness of the pump core during the drug production process, and thus ensuring the quality and safety of the drug. At the same time, the stable clamping facilitates the operator's installation and positioning of the pump core, improving installation efficiency. Attached Figure Description

[0025] Please refer to the following: Figures 1 to 2 The following describes the filling pump installation auxiliary tool provided by this utility model. The filling pump installation auxiliary tool includes a main body 10 and a second working structure 30; the second working structure 30 is disposed on one side of the main body 10, and the second working structure 30 has two clamping parts 31 arranged opposite to each other, the two clamping parts 31 being used to clamp the pump core.

[0026] Before use, the auxiliary tools for installing the filling pump in this embodiment need to be disinfected and sterilized. The disinfection process is as follows: rinse with water for injection, dry and wrap with a double-layer breathing bag, and wipe with disinfectants such as alcohol and sporicidal agents. The sterilization process is: 121℃ moist heat sterilization.

[0027] It should be noted that the two clamping parts 31 are symmetrically distributed. The inner side of the clamping part 31 can be designed as an arc shape or a shape that matches the outer contour of the pump core to ensure full contact with the pump core. The clamping part 31 also has a certain degree of elasticity to adapt to the clamping requirements of pump cores of different sizes. The main body 10 can be a rectangular or irregular block structure to ensure structural stability and ease of hand-holding.

[0028] In the existing technology, during the installation of a filling pump, the pump head of the filling pump needs to be fixed to the filling pump mounting bracket with a special positioning pin. Then, the workers wearing gloves grab the pump core of the filling pump and install the pump core on the pump head to complete the assembly of the filling pump.

[0029] Compared with the prior art, the filling pump installation auxiliary tool provided in this embodiment replaces the traditional method of directly grasping the pump core while wearing gloves during the assembly process. Instead, it fixes the pump core between two clamping parts 31 on the second working structure 30, with the two clamping parts 31 clamping the pump core. The pump core can be picked up and put down by holding the main body 10. After assembling the pump core and pump head, pulling the main body 10 separates the clamping parts 31 from the pump core. The stable clamping of the pump core by the two clamping parts 31 eliminates the need for operators to directly touch the pump core with their hands, fundamentally avoiding the problem of impurities and microbial contamination of the pump core from gloves. This ensures the cleanliness of the pump core during drug production, thereby ensuring drug quality and safety. Simultaneously, the stable clamping facilitates the operator's installation and positioning of the pump core, improving installation efficiency.

[0030] In some embodiments, an improved implementation of the aforementioned body 10 may employ, as follows: Figures 1 to 2 The structure shown. See also Figures 1 to 2 A first function structure 20 is provided on the side of the main body 10 away from the second function structure 30, and a functional hole 21 is provided on the first function structure 20. The first function structure 20 is designed on the side of the main body 10 away from the second function structure 30, that is, the first function structure 20 and the second function structure 30 are located on opposite sides of the main body 10. The distance between the second function structure 30 and the first function structure 20 is large, which can ensure that the second function structure 30 will not interfere with the first function structure 20 when in use, and also makes the zoning of filling pump installation auxiliary tools clear and the layout more reasonable. The functional hole 21 on the first function structure 20 can be hung on a hook for easy storage when not in use, and can also achieve automatic assembly of pump core by a robot arm in cooperation with the functional hole 21 when it is inconvenient for manual handling of the main body 10, thereby improving the convenience and flexibility of operation.

[0031] Optionally, the functional hole 21 can be round, square or hexagonal, etc. When designed as square or hexagonal, it can be adapted to some wrenches and other tools to facilitate the operation of turning.

[0032] In some embodiments, a specific implementation of the above-mentioned filling pump installation auxiliary tool can be as follows: Figures 1 to 2 The structure shown. See also Figures 1 to 2The main body 10, the first functional structure 20, and the second functional structure 30 are integrally molded. For example, injection molding can be used for integral molding. This molding method can ensure that the main body 10, the first functional structure 20, and the second functional structure 30 are tightly connected without obvious seams or gaps, reducing the risk of impurities and microorganisms remaining in the gaps, further ensuring the cleanliness of the filling pump installation auxiliary tool itself, and meeting the stringent requirements for equipment cleanliness in pharmaceutical production. At the same time, integral molding improves the overall structural strength and stability of the filling pump installation auxiliary tool, making it less likely for parts to loosen or fall off, extending the service life of the filling pump installation auxiliary tool, and simplifying the production process and reducing manufacturing costs.

[0033] Optionally, the main body 10, the first functional structure 20, and the second functional structure 30 are all made of polyetheretherketone (PEEK). PEEK has excellent high-temperature resistance and superior chemical stability, ensuring that the filling pump installation auxiliary tool maintains stable performance in the special production environment of biopharmaceuticals (such as high-temperature sterilization, contact with chemical reagents, etc.), and will not release harmful substances that contaminate the drugs, thus ensuring the safety of drug production. At the same time, the corrosion resistance and wear resistance of PEEK also extend the service life of the filling pump installation auxiliary tool, reduce the frequency of replacement of the filling pump installation auxiliary tool, and reduce production costs. In addition, its non-toxic and odorless properties meet industry hygiene requirements, avoiding secondary pollution to the production environment and drugs. Furthermore, the second functional structure 30, after being molded from PEEK, has a certain degree of elasticity, making it easy for the two clamping parts 31 to pry open and clamp the pump core, and providing a certain clamping force when clamping the pump core to prevent the pump core from falling when lifted.

[0034] As an alternative implementation, the main body 10, the first functional structure 20, and the second functional structure 30 can also be connected in a separate structure. The main body 10 and the first functional structure 20, and the main body 10 and the second functional structure 30 can be engaged by means of locking blocks and slots, which facilitates the individual replacement of the first functional structure 20 and the second functional structure 30. One type of second functional structure 30 is suitable for clamping pump cores of a certain size range. For pump cores exceeding this size range, the second functional structure 30 can be replaced to adapt to the pump core of that size, thereby improving the applicability range.

[0035] In some embodiments, a specific implementation of the first functional structure 20 described above may adopt the following approach: Figures 1 to 2 The structure shown. See also Figures 1 to 2The first working structure 20 is a ring structure, and the outer diameter of the ring structure is greater than the width of the main body 10 in the left and right direction. The outer diameter of the ring structure is greater than the width of the main body 10 in the left and right direction. The center of the ring structure coincides with the center line of the main body 10, which can ensure that the ring structure protrudes from the corresponding side wall of the main body 10 on both the left and right sides. When the operator grabs the filling pump installation auxiliary tool, there are two operating methods: (1) grab the outer periphery of the main body 10. The ring structure protruding from the main body 10 can limit the hand and prevent the hand from slipping out of the main body 10; (2) grab the outer periphery of the first working structure 20. The area of ​​the first working structure 20 is larger, which can increase the contact area with the hand and make the operator more stable when holding it.

[0036] When the functional hole 21 is a circular hole, the circular hole is coaxial with the annular structure, and the annular structure is a circular ring structure.

[0037] In some embodiments, a specific implementation of the second functional structure 30 described above may adopt the following approach: Figures 1 to 2 The structure shown. See also Figures 1 to 2 The two clamping parts 31 and the main body 10 together form a semi-circular receiving cavity 32 and an opening 33 located on the side of the receiving cavity 32 away from the first functional structure 20. The two clamping parts 31 and the side of the main body 10 together form a semi-circular receiving cavity 32. The radius of the receiving cavity 32 is adapted to the radius of the pump core, ensuring that the pump core can be placed exactly into the receiving cavity 32. The opening 33 is located on the side of the receiving cavity 32 away from the first functional structure 20. The semi-circular receiving cavity 32 can perfectly fit the arc-shaped surface of the pump core, providing good positioning and support for the pump core, preventing the pump core from shifting or shaking during installation, and improving installation accuracy. The opening 33 facilitates the quick insertion and removal of the pump core from the receiving cavity 32, simplifying the operation steps. At the same time, the width of the opening 33 ensures the stability of the pump core after insertion, preventing the pump core from falling out.

[0038] It should be noted that the width of the opening 33 is constant along the direction away from the first working structure 20. Therefore, the width of the opening 33 can be smaller than the outer diameter of the pump core. Thus, after the pump core is in the receiving cavity 32, the pump core is prevented from coming out of the opening 33 because the width of the opening 33 is smaller than the outer diameter of the pump core.

[0039] Alternatively, the opening 33 gradually increases in width along the direction away from the first functional structure 20. The maximum width of the opening 33 is greater than the outer diameter of the pump core, and the minimum width of the opening 33 is less than the outer diameter of the pump core. In this embodiment, the opening 33 is actually a trumpet-shaped opening 33. The gradually increasing opening 33 serves as a guide, so that the pump core does not need to be precisely aligned when placed into the receiving cavity 32, reducing the difficulty of operation. Especially when the operator is wearing gloves, which affects the flexibility of operation, it can significantly improve the efficiency of pump core placement.

[0040] In some embodiments, an improved implementation of the second functional structure 30 described above can adopt the following approach: Figures 1 to 2 The structure shown. See also Figures 1 to 2 The outer edge of opening 33 is rounded. This involves grinding and polishing to remove sharp edges and create a smooth, rounded transition. This rounding eliminates safety hazards associated with the outer edge of opening 33, preventing operators from being cut on their hands or gloves by sharp edges during the installation of auxiliary tools for the filling pump (such as inserting or removing the pump core). This ensures operator safety and prevents contamination of the pump core due to damaged gloves. The smooth, rounded transition also prevents damage to the pump core's appearance when clamped by installation tools, ensuring pump core quality, extending its lifespan, and improving filling efficiency.

[0041] In some embodiments, an improved implementation of the clamping portion 31 may employ, as follows: Figures 1 to 2 The structure shown. See also Figures 1 to 2 Two clamping parts 31 are located on the left and right sides of the main body 10, respectively. Each clamping part 31 has a recessed positioning groove 34 on the side opposite to the other clamping part 31. The two clamping parts 31 are located on the left and right sides of the main body 10, forming a symmetrical structure with the main body 10. The positioning groove 34 can be designed to be arc-shaped, square, or V-shaped, etc. After the second function structure 30 is used up, the clamping parts 31 can be squeezed by the positioning groove 34 on each clamping part 31, so that the two clamping parts 31 are close to each other. In the event of deformation due to long-term use, the clamping parts 31 can be restored to a certain extent by this method. Furthermore, if the clamping parts 31 loosen while clamping the pump core, the clamping parts 31 can be squeezed by the positioning groove 34 to move the pump core by pinching. The positioning groove 34 provides an operable position for squeezing the clamping parts 31, which is convenient for operation.

[0042] In some embodiments, an improved implementation of the above-mentioned filling pump installation auxiliary tool can adopt the structure described below. (Not shown in the figure) The outer surfaces of the main body 10, the first working structure 20, and the second working structure 30 are provided with anti-slip textures. The anti-slip textures can be processed by engraving or rolling, and can be strip-shaped, grid-shaped, or dot-shaped. Their depth must ensure that it does not affect the overall structural strength and cleanliness of the filling pump installation auxiliary tool. The anti-slip textures increase surface friction, significantly increasing the friction between the outer surface of the filling pump installation auxiliary tool and the operator's gloves. Even if the operator's gloves are wet, it can effectively prevent the filling pump installation auxiliary tool from slipping from their hands, avoiding damage to the pump core or affecting production progress due to the tool slipping.

[0043] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
