Description

Technical Field

[0001] The utility model relates to an injection filling device, in particular to a medium- and long-chain fat emulsion injection filling device adapted to different soft bags, belonging to the technical field of injection filling devices. Background Art

[0002] Medium-chain triglyceride emulsion injection is a uniform and stable fat emulsion composed of refined soybean oil, medium-chain triglycerides, glycerol, lecithin, etc. Its therapeutic importance lies in providing energy and essential fatty acids to patients. Injection refers to sterile solutions (including emulsions and suspensions) made of drugs for injection into the body, as well as sterile powders or concentrated solutions for preparation into solutions or suspensions before use. In the process of bottling the injection, an injection filling device is required to fill the injection drugs.

[0003] However, most of the existing injection filling devices have various problems. For example, in a filling device for fat emulsion injection disclosed in CN217075613U, although it has a sealed liquid storage tank and is provided with a nitrogen inlet and outlet, the air in the tank can be discharged during liquid storage and filling to avoid product oxidation during the liquid storage and filling process; and sealed filling is achieved. However, in this technical solution and most of the current filling devices, the filling head is basically driven to move by a transmission device, and the filling head is moved to the inside of the soft bag before filling. In order to ensure the stability of the soft bag, the bottle mouth is generally locked by a clamping cylinder provided on the filling head to prevent the bottle from tipping over. However, the diameter of the clamping cylinder is often fixed, which results in the bottle diameter that can be fixed by it during filling is also fixed. When facing bottles of different diameters, it is necessary to frequently replace clamping cylinders of different models, which is cumbersome to operate and seriously affects work efficiency.

DETAILED DESCRIPTION

[0020] 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. 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.

[0021] Example 1

[0022] like Figures 1 to 4 As shown, a medium- and long-chain fat emulsion injection filling device adapted for different soft bags includes a transmission rod 1, a receiving tray 2, a filling tube 3, and a bag locking mechanism 4. One end of the transmission rod 1 is connected to the injection filling device body, the receiving tray 2 is coaxially fixed to the other end of the transmission rod 1, and the filling tube 3 is fixed at the axis of the receiving tray 2. A cavity is provided inside the transmission rod 1, and the internal cavity of the filling tube 3 and the internal cavity of the transmission rod 1 are mutually connected. The bag locking mechanism 4 is provided on the receiving tray 2.

[0023] The bag body locking mechanism 4 includes a linkage cylinder 41, a support frame 42, a docking seat 43 and a linkage unit. The linkage cylinder 41 is slidably sleeved on the outside of the filling tube 3, the support frame 42 is fixed to the bottom edge of the support tray 2, and the docking seat 43 is fixed to the outer wall of the linkage cylinder 41. The docking seat 43 and the support frame 42 are arranged in a one-to-one correspondence;

[0024] The linkage unit includes a driven rod 44 and a clamping rod 45. The clamping rod 45 has a V-shaped structure and is rotatably connected to the support frame 42 through a rotating rod. One end of the driven rod 44 is rotatably connected to the docking seat 43, and the other end is rotatably connected to the top end of the clamping rod 45. The other end of the clamping rod 45 is in contact with the soft bag body.

[0025] In the present invention, medium and long chain fat emulsion injection is filled into the soft bag through the filling tube 3, and during filling, the linkage cylinder 41 is in contact with the soft bag, so that the linkage cylinder 41 slides on the filling tube 3, and while sliding, the clamping rod 45 is driven to be linked through the driven rod 44, so that one end of the clamping rod 45 is in contact with the bag body of the soft bag, and the soft bag is locked, so that the filling device can be applied to different soft bags and lock the soft bags to ensure the stability of the soft bags. It is simple and practical, avoids frequent replacement of bag body sleeves of different models, and greatly improves work efficiency.

[0026] Example 2

[0027] like Figures 1 to 4 As shown, in addition to all the technical features of the first embodiment, this embodiment also includes:

[0028] An abutment disk 46 is coaxially fixed to the bottom of the linkage cylinder 41. A through hole that penetrates the internal cavity of the linkage cylinder 41 is opened at the center of the abutment disk 46, and a rubber gasket is provided at the bottom of the abutment disk 46. The abutment disk 46 abuts against the bag opening of the bag body to prevent the injection liquid from spraying out.

[0029] A limiting groove 47 is provided on the side wall of the linkage cylinder 41, and a positioning rod 48 is fixed to the outer wall of the filling tube 3. The positioning rod 48 slides and is engaged in the limiting groove 47. The positioning rod 48 limits the linkage cylinder 41 and limits the displacement of the linkage cylinder 41.

[0030] A return spring 5 is provided on the outside of the filling tube 3. One end of the return spring 5 abuts against the linkage cylinder 41, and the other end abuts against the support tray 2. The elastic force of the return spring 5 enables the linkage cylinder 41 to be quickly reset, thereby enabling the clamping rod 45 to be quickly opened to facilitate the next filling operation.

[0031] A locking clamp 6 is rotatably connected to one end of the clamping rod 45 close to the soft bag body, and a rubber pad is provided on the abutting surface between the locking clamp 6 and the bag body. The locking clamp 6 abuts against the bag body, so that the clamping rod 45 can firmly lock the bag body, and at the same time, the rubber pad is provided to prevent damage to the surface of the bag body.

[0032] Working principle: When using the injection filling device, first place the bag body at the bottom of the filling tube 3, and then drive the transmission rod 1 downward through the filling device to move the filling tube 3 into the bag body, and while moving, the abutment plate 46 abuts against the bag opening and pushes the linkage cylinder 41 to slide on the filling tube 3. At this time, the linkage cylinder 41 drives the driven rod 44 to link, and the driven rod 44 synchronously drives the clamping rod 45 to rotate on the support frame 42 until the locking chuck 6 provided at one end of the clamping rod 45 abuts against the bag body, and the soft bag is locked to start the filling operation. After the filling is completed, the elastic force of the reset spring 5 pushes the linkage cylinder 41 to reset, thereby driving the clamping rod 45 to open, so as to facilitate the next filling operation.

[0033] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.

[0034] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
