Description

Technical Field

[0001] This invention relates to the field of medical dressing packaging technology, specifically to an automatic aseptic packaging device for medical dressings. Background Technology

[0002] Medical dressings are basic consumables widely used in medical activities, and their sterility is directly related to patient safety and infection control. According to the requirements of the Good Manufacturing Practice for Medical Devices, medical dressings must be sterilized and packaged in a sterile barrier system after production to maintain their sterility until clinical use.

[0003] Medical dressings include: Traditional gauze dressings (made of absorbent cotton or gauze, with strong exudate absorption capacity, but prone to sticking to the wound, and may pull on newly formed tissue when changing); Transparent film dressings (polyurethane material, transparent, waterproof, and breathable, facilitating wound observation, suitable for superficial abrasions or as a fixation dressing); Hydrocolloid dressings (containing hydrophilic particles, forming a gel after absorbing a small amount of exudate, providing a moist and closed environment for the wound, often used in the early stages of pressure ulcers or small-area superficial burns); Foam dressings (polyurethane foam structure, highly absorbent, soft and cushioning, suitable for wounds with a lot of exudate, such as lower extremity ulcers); Alginate dressings (extracted from seaweed, forming a gel upon contact with exudate, with good hemostatic and filling effects, often used to fill cavitary wounds with exudate or minor bleeding); Silver-containing dressings (exerting broad-spectrum antibacterial effects by releasing silver ions, often used for wounds with infection risk or local infection).

[0004] For example, patent CN216136183U discloses a sterile packaged nonwoven surgical dressing kit, comprising multiple nonwoven dressing sheets and an outer packaging component. The multiple nonwoven dressing sheets are arranged in an unfolded state, stacked sequentially, and then folded at least once to form a folded dressing stack. The outer packaging component wraps around the folded dressing stack and seals it for sterilization. Each nonwoven dressing sheet includes an absorbent pad made of spunlace nonwoven fabric and at least one X-ray tracking element, with the at least one X-ray tracking element disposed on the absorbent pad. The sterile packaged nonwoven surgical dressing kit provided according to the embodiments of this utility model has higher safety and better absorbency. In addition, it facilitates automated processing, increasing production speed by 5 to 10 times, and reducing manufacturing costs.

[0005] Existing medical dressing packaging devices lack a mechanism for positioning and limiting the outer top cover of the dressing, making it impossible to achieve precise alignment between the top cover and the base plate. This can cause misalignment and misalignment during the packaging process, ultimately resulting in poor sealing, increased packaging defects, and reduced packaging efficiency. To address this, we propose an automated aseptic packaging device for medical dressings. Summary of the Invention

The outer wall of the second fixing strip 87 is slidably connected to the inner wall of the second sliding groove 83.

[0031] Specifically, the moving seat 81 can be moved by the side plate 84, the second electric push rod 85, the moving seat 81, the first fixing bar 86 and the second fixing bar 87. The first fixing bar 86 and the second fixing bar 87 can guide and limit the moving seat 81, thereby improving the stability of the moving seat 81 during the movement.

[0032] In this embodiment, the sealing mechanism 7 includes two symmetrically arranged top plates 71. The two top plates 71 on the same side are fixedly installed on the outer wall of the protective cover body 51 at one end. A first electric push rod 72 is fixedly installed at the lower end of each top plate 71. A sealing plate 73 is fixedly installed at the telescopic ends of the two first electric push rods 72. The sealing plate 73 is slidably connected to the outer wall of the protective cover body 51 at one end.

[0033] Specifically, a closing mechanism 7 is provided, which performs opening and closing actions on the first opening slot 52. During the packaging process, the closing mechanism 7 closes the first opening slot 52 to form a sealed space. When it is necessary to load or unload materials or perform maintenance, the closing mechanism 7 opens the first opening slot 52, thereby realizing flexible opening and closing control of the first opening slot 52 and ensuring the continuity of the packaging operation and the convenience of operation.

[0034] In this embodiment, each corner of the lower end of the packaging device base 1 is fixedly installed with a stabilizing seat 2, and the front end of the packaging device base 1 is provided with multiple door bodies 4 that are evenly distributed.

[0035] Specifically, the stability of the packaging device base 1 can be improved by using the stabilizing seat 2.

[0036] In this embodiment, the outer wall of the C-shaped rod 817 is slidably connected to the end face of the placement box 810, and the spring 818 is sleeved on the outside of the C-shaped rod 817.

[0037] Specifically, ensure that the C-shaped rod 817 does not interfere with the placement box 810 during movement, and ensure that the spring 818 does not interfere with the outer end of the C-shaped rod 817 during compression and rebound.

[0038] In this embodiment, both ends of the rotating shaft 812 are inserted through the front and rear sides of the rotating gear 811, and the rear end of the rotating shaft 812 is inserted through the rear side of the placement box 810.

[0039] Specifically, ensure that the rotating shaft 812 does not interfere with the placement box 810 during rotation.

[0040] In this embodiment, a support platform 57 is fixedly installed on the right end of the base plate 56. The support platform 57 is located on the left side of the dressing external top cover limiting mechanism 8. A transparent glass 53 is fixedly installed on the front end of the protective cover body 51.

[0041] Specifically, the outer top cover of the dressing conveyed from the first conveyor belt 55 can be supported and placed by the support platform 57.

[0042] Working principle: During operation, the first conveyor belt 55 intermittently conveys the outer top cover of the dressing, the second conveyor belt 6 intermittently conveys the dressing and the base plate 56 supporting the dressing, and the third conveyor belt 9 conveys the packaged assembly. An external power supply and controller drive the second electric push rod 85, which in turn moves the movable seat 81. The first fixing bar 86 and the second fixing bar 87 limit and guide the movable seat 81. The movable seat 81 then moves two symmetrically arranged dressing outer top cover limiting plates 819 to the upper side of the dressing outer top cover on the support platform 57. Subsequently, the third electric push rod 89 and the stepper motor 815 are driven. The third electric push rod 89 drives the placement box 810 and the dressing outer top cover limiting plate 819 to move down. When the dressing outer top cover limiting plate 819 is on both sides of the dressing outer top cover, the output end of the stepper motor 815 drives the right rotating shaft 812 to rotate clockwise. The right rotating shaft 812 drives the right rotating gear 811 to rotate clockwise. The two rotating rollers 813 rotate in opposite directions. The rotating rollers 813 drive the arc plate 814 to rotate. The two arc plates 814 drive the contact block 816, the C-shaped rod 817 and the dressing outer top cover limiting plate 819 to move closer to each other. The spring 818 releases its elastic force, and the two dressing outer top cover limiting plates 819 simultaneously limit the dressing outer top cover on both sides. The outer top cover of the dressing is moved by the second electric push rod 85 and the third electric push rod 89. When the lower end of the outer top cover of the dressing contacts the upper end of the top plate 71 supporting the dressing, the outer top cover of the dressing and the top plate 71 supporting the dressing are glued together to form a whole.

[0043] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
