Description

Technical Field

[0001] The utility model relates to the packaging field of a gastric retention system, in particular to a capsule filling jig of a gastric retention system. Background Art

[0002] Patients on long-term medication regimens have poor medication compliance, and current methods to improve compliance rates, such as educational interventions and counseling, have achieved only modest improvements. One way to reduce the frequency of dosing of oral dosage forms over extended durations is to add a self-expansion mechanism to the dosage form that physically prevents the dosage form from leaving the gastric cavity. In current gastric retention systems, in order to be encapsulated and retained in the stomach, the gastric retention system is generally prepared from an elastic polymer to form an elastomer. The elastomer generally includes an elastic center and an extension arm. The elastomer has two configurations, folded and unfolded. The elastomer is filled into the capsule shell in a folded configuration. After being taken into the body, the elastomer extension arm unfolds to form an unfolded configuration. There has been a lot of research in the prior art on gastric retention systems. For example, patents US11576859B2 or US20190262265A1 introduce a variety of star-shaped gastric retention systems, as shown in the attached disclosure. Figure 1 The structure has 6 elastic extension arms.

[0003] When preparing a gastric retention system product, the gastric retention system needs to be filled into a capsule shell in a folded configuration, and existing devices cannot quickly and effectively complete the filling and packaging of the gastric retention system. Utility Model Content

[0031] In order to explain the technical content, structural features, achieved objectives and effects of the technical solution in detail, the following is a detailed description in conjunction with specific embodiments and accompanying drawings.

[0032] See also Figure 1-6 The present embodiment discloses a capsule filling jig for a gastric retention system, comprising a mounting frame 1, a filling base 2 and a pressing assembly 3, wherein a mounting plate 11 and a vertical slide rail 12 are fixed to the mounting frame 1, a filling mold 13 is provided on the mounting plate 11, a filling through hole 131 is provided on the filling mold 13, the vertical slide rail 12 is located above the mounting plate 11, the filling base 2 is located below the mounting plate 11, a filling groove 21 corresponding to the position of the filling through hole 131 is provided on the filling base 2, and the pressing assembly 3 comprises a first pressing rod 31 and a second pressing rod 32 vertically arranged, the first pressing rod 31 and the second pressing rod 32 are located above the mounting plate 11, the first pressing rod 31 and the second pressing rod 32 are both slidably arranged on the vertical slide rail 12, a sliding channel 321 is axially arranged on the second pressing rod 32, the first pressing rod 31 moves through the sliding channel 321, and the first pressing rod 31 and the second pressing rod 32 correspond to the position of the filling through hole 131.

[0033] In this embodiment, the first pressure rod 31 moves through the axial sliding channel 321 of the second pressure rod 32. The first pressure rod 31 is set to be a pressure rod with a smaller diameter. During the pressing process, it will not hinder the initial folding of the extension arm 42 of the gastric retention system 4. The second pressure rod 32 is set to be a pressure rod with a larger diameter. The diameter of the second pressure rod 32 is larger than the diameter of the first pressure rod 31, but not larger than the diameter of the filling through hole 131. After the gastric retention system 4 is pressed down and folded, the first pressure rod 31 with a small diameter rises, and the second pressure rod 32 with a large diameter is pressed down, thereby pressing the gastric retention system 4 down into the capsule shell 5 in the filling groove 21, thereby completing the filling.

[0034] A fixed base 14 is fixed at the bottom of the mounting frame 1, and the filling base 2 is movably arranged on the fixed base 14. A protruding guide rail 141 is arranged on the fixed base 14, and a positioning block 142 is arranged at one end of the guide rail 141. The filling base 2 is provided with a slide groove 22 corresponding to the guide rail 141, and the positioning block 142 is blocked and connected with the filling base 2. The arrangement of the positioning block 142 and the guide rail 141 is conducive to positioning the filling base 2 under the mounting plate 11.

[0035] In this embodiment, a leveling device is provided on the bottom surface of the fixed base 14, which is conducive to the horizontal placement of the entire device.

[0036] The positioning block 142 and the filling base 2 are provided with correspondingly positioned adsorption magnetic blocks 143. The adsorption magnets can fix the filling base 2 and the positioning block 142, thereby facilitating the flexible fixation of the filling base 2.

[0037] The vertical slide rail 12 includes a vertically arranged guide shaft 121, and the top ends of the first pressure rod 31 and the second pressure rod 32 are respectively fixed with a first movable plate 33 and a second movable plate 34, the first movable plate 33 is located above the second movable plate 34, and the first movable plate 33 and the second movable plate 34 are both provided with a linear bearing 35, and the linear bearing 35 is sleeved on the guide shaft 121. The cooperation between the guide shaft 121 and the linear bearing 35 enables the first pressure rod 31 and the second pressure rod 32 to smoothly perform vertical movements up and down.

[0038] In this embodiment, there are two guide shafts 121 which are relatively arranged on both sides of the pressing assembly 3. The first movable plate 33 and the second movable plate 34 are transversely long strips. Both ends of the first movable plate 33 and the second movable plate 34 are provided with linear bearings 35.

[0039] The first movable plate 33 is provided with first positioning grooves 36 on both opposite side surfaces, the mounting frame 1 is provided with first elastic positioning beads 15, the first positioning grooves 36 and the first elastic positioning beads 15 are engaged with each other, the second movable plate 34 is provided with second positioning grooves 37 on both opposite side surfaces, the mounting frame 1 is provided with second elastic positioning beads 16, the second positioning grooves 37 and the second elastic positioning beads 16 are engaged with each other.

[0040] The provision of the elastic positioning beads plays a role in positioning and fixing the first movable plate 33 and the second movable plate 34, preventing the two pressure rods from being in a downward pressure state when there is no external force, further facilitating the use of the device.

[0041] In this embodiment, the positioning groove is a transverse groove on the movable plate, the cross-section of the positioning groove is an arc shape, and the elastic positioning bead is embedded with a spring. When an external force is applied to press the movable plate downward, the elastic positioning bead will pop out from the positioning groove.

[0042] A first spring 122 and a second spring 123 are sleeved on the guide shaft 121 . The first spring 122 is arranged between the first movable plate 33 and the second movable plate 34 , and the second spring 123 is arranged between the second movable plate 34 and the mounting plate 11 .

[0043] The first spring 122 and the second spring 123 prevent the first pressure rod 31 and the second pressure rod 32 from being pressed down suddenly, and maintain the stability of the process of pressing down the folded gastric retention system 4. At the same time, when the first movable plate 33 and the second movable plate 34 lose external force, the springs play a certain reset role.

[0044] In some embodiments, due to the setting of the first spring 122, when the first movable plate 33 is pressed downward, it will have a certain downward pressure on the second movable plate 34. In order to avoid the downward pressure of the second movable plate 34 at this time, the locking force of the second elastic positioning bead 16 can be set to be greater than the downward pressure of the first movable plate 33, or the operator can manually hold the second movable plate 34 to fix it when pressing down the first movable plate 33.

[0045] The first movable plate 33 and the second movable plate 34 are provided with pressing handles 38 protruding from their sides, respectively. The pressing handles 38 of the first movable plate 33 and the second movable plate 34 are staggered with each other. The pressing handles 38 are convenient for the staff to apply force to press down.

The positioning bosses 132 are used to fix the gastric retention system 4.

[0047] In this embodiment, the installation opening 111 passes through the upper and lower surfaces of the installation plate 11 , and a boss is provided in the installation opening 111 for installing the filling mold 13 .

[0048] The top opening of the filling through hole 131 has a rounded chamfer, which is conducive to the smooth folding of the extension arm 42 of the gastric retention system 4, so that the gastric retention system 4 is pressed down to fill the lower capsule shell 5.

[0049] The structure of the gastric retention system 4 is shown in the attached Figure 1 As shown, the gastric retention system 4 includes an elastic core 41 and elongated arms 42.

[0050] In this embodiment, the gastric retention system 4 having six extension arms 42 is folded and filled. Six spaced and surrounding positioning bosses 132 are provided on the upper surface of the filling mold 13.
