Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and particularly to a disposable sterile surgical pack, a packaging device and a packaging method thereof. Background Art

[0002] Surgical packs usually consist of a large drape, surgical sheets, surgical fenestrated drapes, surgical gowns, sterile gloves and other instrument objects, etc., and other surgical accessories are added according to the requirements of actual surgical categories. Although there are already a variety of disposable sterile surgical packs on the market, their designs are generally too simple. When surgery needs to be performed in the emergency room, at the scene of an out-of-hospital accident or in a field environment, due to the relatively scattered various surgical instruments and items inside, and the inconvenient disassembly and assembly of the surgical pack, the items inside will scatter everywhere when disassembling and assembling, increasing the possibility of contamination of sterile items. At the same time, it also brings great inconvenience to the preoperative preparation of medical staff and increases the preoperative preparation time.

[0003] On the other hand, the current surgical packs are not provided with protective components and are only uniformly loaded through an outer package, and cannot well protect the surgical accessories inside. Especially during transportation, if the surgical pack is squeezed, the surgical accessories inside may be damaged. Seriously, the sharp accessories inside may even pierce through the surgical pack, causing all the accessories inside to be contaminated and thus unable to be used.

[0004] Traditional surgical packs are mostly completed manually in the packaging process: First step, unfold the large drape; Second step, stack relevant medical accessories (surgical sheets, surgical fenestrated drapes, surgical gowns, sterile gloves, suture threads, medical pliers, etc.) in the center of the large drape; Third step, manually wrap the medical accessories placed therein with the large drape; Fourth step, put the wrapped simple surgical pack into a plastic packaging bag for secondary packaging to complete. The above packaging method is cumbersome, the finished surgical pack is simple and of poor quality. At the same time, manual packaging increases the risk of contamination of the surgical pack, and manual packaging has low production efficiency, high input cost, high labor intensity and low product quality. Summary of the Invention

[0005] In view of the above deficiencies, the present invention provides a disposable sterile surgical pack, a packaging device and a packaging method thereof. The surgical pack has a simple structure and is convenient for disassembly and assembly, solving the problem of the current trouble that surgical accessories are scattered and contaminated during the disassembly and assembly process.

[0027] A packaging method for a disposable sterile surgical pack, the packaging method comprising the following steps:

[0028] S1: At least two staff members are arranged on the conveying mechanism. One is located at the feeding end of the conveying mechanism and is used to manually place the surgical pack main body on the placing station. The other is located at the feeding station and is used to perform the first-layer sealing operation after the accommodation cavity is filled with materials. The staff member located at the feeding end of the conveying mechanism places the surgical pack main body in the accommodation frame, then spreads out the four sealing cloths located at the opening of the accommodation cavity one by one and flatly places them on the first to fourth turning plates, and then opens the drawstring sealing layer to the maximum extent.

[0029] S2: The corresponding medical accessory materials are sorted and flow to the conveying site from the material conveying line. The elastic force of the torsion spring at the conveying site is sufficient to support the weight of the corresponding medical accessory materials. When the sensing mechanism on the feeding mechanism detects that the placing station carrying the surgical pack main body reaches directly below the conveying site, the control center controls the conveying mechanism to pause the conveying, and the feeding mechanism performs the batching action. The telescopic push rod drives the auxiliary pressing plate to press downwards, the turning supporting plate turns to open the channel, releases the materials, and the medical accessories are filled into the accommodation cavity. During the downward and upward movement of the auxiliary pressing plate, the second set of medical accessories sequentially conveyed on the material conveying line is blocked from flowing into the conveying site until the auxiliary pressing plate returns above the conveying site again, and the conveying site feeds materials again.

[0030] S3: The staff at the feeding station performs the first - layer sealing operation on the main body of the surgical pack that has completed material configuration. One hand of the staff holds the tightening rope, and the other hand pushes the rope - tightening buckle to tie up the mouth - covering cloth, completing the first - layer sealing.

[0031] S4: After completing the above steps, the control center controls the conveying mechanism to continue the conveying operation. After the sensing mechanism on the laminating mechanism detects that the placement station carrying the main body of the surgical pack reaches the laminating station, the control center controls the conveying mechanism to pause the conveying, and the laminating mechanism performs the second - layer sealing operation. The control center controls the first to fourth laminating driving parts to flip in sequence to flip the first to fourth flipping plates in sequence. The sequential flipping of the first to fourth flipping plates causes the mouth - covering cloths located above to cover and connect relatively in sequence, completing the second - layer sealing.

[0032] S5: The control center controls the conveying mechanism to continue the conveying operation. When the conveying mechanism carries the main body of the surgically - packed pack that has been sealed through the blanking port, the vacuum - adsorption opening part opens the entrance of the protective packaging located directly below the blanking port so that the packed main body of the surgical pack falls into the protective packaging.

[0033] S6: The main body of the surgical pack falls from the blanking port into the protective packaging, and the material receiving line moves the protective packaging carrying the main body of the surgical pack to the sealing and sterilizing department.

[0034] S7: The sealing - driving telescopic push rod drives the fixed clamping block and the moving clamping block to clamp each other, and blows sterilizing gas (here the sterilizing gas refers to ethylene oxide) into the protective packaging through the air delivery pipe. The heating sheet on the fixed clamping block or the moving clamping block generates heat after being electrified, and seals the protective packaging through the heating sheet.

[0035] S8: After completing the above steps, the material receiving line continues to move the surgically - packed pack that has been sealed to a designated position for release - the electric gripper releases the clamped main body of the surgical pack, and the packed main body of the surgical pack falls into the designated receiving position.

[0036] Compared with the prior art, the beneficial effects of the present invention are:

[0037] 1. The present invention provides a disposable sterile surgical pack. The surgical pack realizes full protection of internal items through three - layer protection (protective packaging, protective carrier, and drawstring - sealing layer), reducing the possibility of damage to internal items caused by extrusion or impact, improving the aseptic effect at the same time, reducing the possibility of being contaminated, and being convenient for disassembling, assembling, taking, and placing items. It overcomes the problem of traditional single - layer packaging where internal items may scatter during disassembly and use, resulting in possible contamination.

[0038] 2. The surgical kit provided by the present invention has a simple and novel structure, wherein the protective carrier is similar to the packaging structure of a box, which is convenient for assembly and disassembly, and the medical items inside are arranged neatly, orderly and stably, thereby improving the convenience and efficiency of access during operation.

[0082] Preferably, to more clearly understand the operation steps of the device:

[0083] A packaging method for a disposable sterile surgical pack, the packaging method including the following steps:

[0084] S1: At least two staff members are arranged on the conveying mechanism 300. One is located at the feeding end of the conveying mechanism 300 and is used to manually place the surgical pack main body 200 on the placing station 340. The other is located at the feeding station and is used to perform the first layer sealing operation after the accommodating cavity 211 is filled with materials. The staff member located at the feeding end of the conveying mechanism 300 places the surgical pack main body 200 in the accommodating frame 341, then spreads the four sealing cloths 212 located at the opening of the accommodating cavity 211 flat on the first to fourth turning plates one by one, and then opens the drawstring sealing layer 220 to the maximum extent;

[0085] S2: The corresponding medical accessory materials are sorted and flow from the material conveying line 510 to the conveying site 520. The elastic force of the torsion spring on the conveying site 520 is sufficient to support the weight of the corresponding medical accessory materials. When the sensing mechanism on the feeding mechanism 500 detects that the placement station 340 carrying the surgical pack body 200 reaches directly below the conveying site 520, the control center controls the conveying mechanism 300 to pause the conveying, and the feeding mechanism 500 performs the batching action. The telescopic push rod 531 drives the auxiliary pressing plate 532 to press downwards. The flipping support plate 523 flips to open the channel and release the materials, and the medical accessories are filled into the accommodating cavity 211. The auxiliary pressing plate 532 prevents the second set of medical accessories sequentially conveyed on the material conveying line 510 from flowing into the conveying site 520 during the descending and ascending processes until the auxiliary pressing plate 532 returns above the conveying site 520 again, and the conveying site 520 feeds materials again;

[0086] S3: The staff at the feeding station performs the first-layer sealing operation on the surgical pack body 200 that has completed the material configuration. One hand of the staff holds the tightening rope 222, and the other hand pushes the rope buckle 223 to tie up the mouth cloth 221 to complete the first-layer sealing;

[0087] S4: After completing the above steps, the control center controls the conveying mechanism 300 to continue the conveying action. When the sensing mechanism on the laminating mechanism 400 detects that the placement station 340 carrying the surgical pack body 200 reaches the laminating station, the control center controls the conveying mechanism 300 to pause the conveying, and the laminating mechanism 400 performs the second-layer sealing action. The control center controls the first to fourth laminating driving parts to flip in sequence to flip the first to fourth flipping plates in sequence. The sequential flipping of the first to fourth flipping plates enables the sealing cloth 212 located above to be sequentially covered and connected relatively to complete the second-layer sealing;

[0088] S5: The control center controls the conveying mechanism 300 to continue the conveying action. When the conveying mechanism 300 carries the sealed surgical pack body 200 past the blanking opening 311, the vacuum adsorption opening part 620 opens the entrance of the protective packaging 100 located directly below the blanking opening 311 so that the packaged surgical pack body 200 falls into the protective packaging 100;

[0089] S6: The surgical pack body 200 falls from the blanking opening 311 into the protective packaging 100, and the material receiving line 610 moves the protective packaging 100 carrying the surgical pack body 200 to the sealing and sterilizing part 630;

[0090] S7: The sealing drive telescopic push rod 634 drives the fixed clamping block 632 and the moving clamping block 633 to clamp each other, and blows sterilizing gas, which is ethylene oxide here, into the protective package 100 through the air delivery pipe 631. The blown gas gradually penetrates into the surgical pack body 200 to complete the sterilization operation. The excess gas is discharged from the entrance of the protective package 100. Then, the heating sheet on the fixed clamping block 632 or the moving clamping block 633 is electrified to generate heat, and the protective package 100 is sealed by the heating sheet;

[0091] S8: After the above steps are completed, the material receiving line 610 continues to move the sealed surgical pack body 200 to a designated position for release - the electric claw 613 releases the clamped surgical pack body 200, and the packaged surgical pack body 200 falls into the designated receiving position.

[0092] As described above, the above is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by those skilled in the art within the technical scope disclosed by the present invention should be covered by the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope of the claims.
