Description

Technical Field

[0001] This utility model belongs to the field of medical auxiliary device technology, specifically a disposable intraoperative dressing collection bag. Background Technology

[0002] Intraoperative dressing collection bags are widely used in various surgical procedures, especially in minimally invasive surgery. They can be used not only to collect dressings such as gauze and cotton balls used during surgery, but also to collect surgical waste fluids, blood, and other liquid substances. Furthermore, in some specialized surgeries, such as laparoscopic myomectomy, specially designed disposable collection bags can be used to collect the fragmented myomectomy tissue.

[0003] Existing intraoperative dressing collection bags have a relatively simple structure, generally made of polymer fabric. When the collection bag is full, closing the bag may squeeze out the blood and fluid absorbed by the collected gauze, cotton balls, and other waste materials, causing contamination of the operating table. At the same time, when collecting waste materials that cannot be mixed, two collection bags must be used to collect them separately, resulting in waste of collection bags. In addition, existing collection bags are generally placed on the operating table or hung on special instruments, making it difficult to conveniently hang them on the edge of the operating table to save table space.

[0004] Therefore, it is necessary to propose a disposable intraoperative dressing collection bag with classification storage and load indication functions, which can be easily hung to save space. Utility Model Content

[0005] To address the aforementioned issues, the purpose of this invention is to provide a disposable intraoperative dressing collection bag that achieves categorized storage through several inner bags within an outer packaging, uses a piston to measure and indicate the weight of the inner bags, and employs various fixing methods to enable flexible use in multiple scenarios.

[0006] To achieve the above objectives, the technical solution of this utility model is as follows: a disposable intraoperative dressing collection bag, including an outer package, an inner package with several openings sewn into the inner wall of the outer package that are consistent with the outer package, a number of skeletons provided inside the side wall of the outer package away from the inner package, the skeletons extending into the bottom wall of the outer package, and piston assemblies provided between the bottom wall of the inner package and the inner bottom wall of the outer package.

[0007] The piston assembly includes several inner piston plates and several inner piston cylinders. The upper surface of each inner piston plate is fixedly connected to the inner bottom wall. The outer peripheral sidewalls of each inner piston plate are slidably connected to the inner piston cylinders. The bottom walls of each inner piston cylinder are fixedly connected to the skeleton inside the outer bottom wall. Each inner piston cylinder has an indicator piston cylinder connected to the side closest to the outer side wall. Each indicator piston cylinder enters the interior of the outer side wall and extends upward. Each indicator piston cylinder has an indicator piston plate slidably connected inside. The piston cylinders between the inner piston plates and the indicator piston plates are filled with fluid.

[0008] The basic principle is: the piston cylinder is supported by the frame and the outer bottom wall in a suspended state, which enhances the sensitivity of the piston. The internal weight change of the inner piston plate is converted into the process of the indicator piston plate through the piston's communication principle, which clearly shows the weight of the collected object.

[0009] The beneficial effects of the basic design are: 1. By setting a skeleton inside the side wall of the outer casing away from the inner casing and extending it into the bottom wall of the outer casing, a stable support is provided for the entire structure. This design not only enhances the stability of the overall structure but also allows the piston assembly to respond more sensitively to stress, improving the accuracy of measurements.

[0010] 2. Utilizing the principle of piston continuity, the weight change within the inner package is converted into the displacement of the indicating piston plate. This design allows users to intuitively understand the weight of the collected items within the inner package by observing the position of the indicating piston plate, eliminating the need for additional measuring tools and improving ease of use.

[0011] 3. The clever use of space in the inner and outer packaging design, including the inner piston cylinder and the indicator piston cylinder, not only saves space but also makes the entire structure more compact. This design helps reduce the overall size of the device, making it easier to carry and store.

[0012] Furthermore, the top of the inner side wall of the outer casing is provided with Velcro.

[0013] The beneficial effects of the basic solution are: 1. As a quick-connect and fastening device, Velcro ensures a tight fit between the outer and inner packaging. This not only prevents items from accidentally falling out, but also, to a certain extent, prevents the intrusion of external factors such as dust and moisture, improving overall sealing and security.

[0014] 2. The use of Velcro allows users to easily and quickly open or close the outer and inner bags without complicated operations or tools. This convenience is especially important when it is necessary to frequently take out and put away items or to perform quick checks.

[0015] 3. By adjusting the position or tightness of the Velcro, users can adjust the closure of the outer bag according to actual loading needs. This flexibility allows the device to adapt to the loading needs of items of different sizes, shapes, and weights.

[0016] 4. Velcro is typically made of high-strength materials, offering excellent durability and reliability. It maintains a stable connection even under prolonged use or frequent opening and closing.

[0017] Furthermore, zippers are provided on the top of the inner sidewalls of the inner bag.

[0018] The basic solution has the following advantages: the zipper at the inner opening allows for easy sealing of the inner package, preventing liquid leakage and gas evaporation, thus ensuring the accuracy of the weight detection of the collected material.

[0019] Furthermore, an adhesive patch is provided on the top of the outer wall of the outer packaging, away from the inner packaging.

[0020] The benefits of the basic design are: 1. The adhesive design enhances the adhesion between the outer casing and the installation surface (such as walls, countertops, etc.), preventing the device from slipping or falling under gravity. This is crucial for ensuring the stability and safety of the device during use.

[0021] 2. As an adhesive connector, the adhesive allows users to easily fix the device in the desired location without the need for complicated installation tools or screws. At the same time, the adhesive is easy to remove when the device needs to be moved or rearranged, leaving no residue or damaging the mounting surface.

[0022] Furthermore, release paper is attached to the adhesive tape on the top of the outer side wall of the outer packaging.

[0023] The beneficial effects of the basic solution are: 1. The main function of the release paper (also known as release liner or protective paper) is to protect the adhesive material on the surface of the adhesive, preventing it from being contaminated by dust, dirt, or moisture before use. This ensures that the adhesive maintains its optimal tack when the user needs to apply it, thus achieving a firm and secure fixation.

[0024] 2. Adhesive tape with release paper is safer during storage and transportation. Release paper prevents the tapes from sticking together, avoiding loss of adhesion due to accidental contact or pressure. At the same time, release paper also provides cushioning, protecting the tapes from physical damage.

[0025] 3. The release paper design allows users to easily peel off and stick the adhesive tape without additional cleaning or preparation. This simplifies the operation and improves user efficiency.

[0026] Furthermore, a label holder is provided on one side of the outer wall of the packaging, and label stickers are placed inside the label holder.

[0027] The benefits of the basic solution are: 1. The label design allows users to clearly label the contents, purpose, weight limits, or other important information on the inner and outer packaging. This helps users quickly identify and manage the device, improving work efficiency.

[0028] 2. The label holder design allows labels to be neatly stored on the outer wall of the packaging without taking up extra space. At the same time, the label holder can also serve as a decorative element, enhancing the overall aesthetics of the installation.

[0029] Furthermore, the outer surface of the piston cylinder is engraved with indicator scales and warning lines.

[0030] The beneficial effects of the basic design are: 1. The indicating scale on the outer surface of the piston cylinder allows users to intuitively read the piston's displacement, thereby accurately measuring and determining the weight of the collected material inside the container. This design improves the accuracy and reliability of the measurement, helping users make more precise judgments and decisions.

[0031] 2. The warning line provides users with a visual reference point to indicate the limits of wastewater overflow when the collection bag is closed. This design helps prevent overloading or excessive use, ensuring the safety and stability of the device.

[0032] 3. The design of the indicator scale and warning lines allows users to easily read and understand the device's status without the need for additional measuring tools or professional knowledge. This reduces the difficulty of operation and improves user efficiency.

[0033] Furthermore, it indicates that the outer wall of the piston cylinder is a transparent layer.

[0034] The beneficial effects of the basic design are: 1. The transparent outer wall allows users to directly see the inside of the piston cylinder, including the piston position and the liquid level. This intuitive visual feedback helps users quickly understand the status of the device and monitor it without opening or disassembling it.

[0035] 2. When the outer wall of the indicating piston cylinder is made of a transparent material, users can more accurately read the piston position or liquid level, thus enabling more precise measurements. This helps reduce errors and improves the accuracy and reliability of measurements.

[0036] Furthermore, both the outer and inner layers are transparent.

[0037] The beneficial effects of the basic design are: 1. When both the outer and inner packaging are made of transparent materials, users can observe the internal workings of the device from all angles. The filling status and type of the inner packaging, as well as the piston's movement trajectory, are all clearly visible. This comprehensive visual feedback provides users with richer information, helping them make more accurate judgments and decisions.

[0038] 2. The transparent material allows users to clearly see the position, shape, and quantity of objects within the enclosure, enabling more accurate measurements. For example, when measuring liquid volume, users can visually see the liquid level; when measuring solid mass, users can estimate its weight by observing the stacking of objects. This design significantly improves the accuracy and reliability of measurements.

[0039] 3. The transparent material design allows users to separate items without opening or disassembling the device, which helps avoid opening the collection bag for separation and reduces the possibility of contamination due to mistakes.

[0040] Furthermore, a handle is provided at the top of the outer side wall of the outer casing.

[0041] The benefits of the basic design are: 1. The handle design allows users to easily grasp and lift the entire device, making both short-distance transport and long-distance movement much more convenient. This greatly improves work efficiency and reduces delays and labor costs caused by difficulties in handling.

[0042] 2. Handles are typically designed near the device's center of gravity, which helps maintain the device's balance during transport and reduces safety risks caused by swaying or tilting. Furthermore, the material and shape of the handles are carefully designed to ensure a comfortable grip and prevent hand injuries during transport.

[0043] 3. In addition to its carrying function, the handle can also serve as a support or anchor point during operation. For example, when it is necessary to fix the device in a certain position or perform certain specific operations, the user can use the handle to stabilize the device and ensure smooth operation.

[0044] 4. The handle design makes it easier for users to operate and use the device, improving the user experience. Users don't need to worry about difficulties in carrying or operation, thus making them more willing to use and recommend the device. Attached Figure Description

[0049] The following detailed description illustrates the specific implementation method:

[0050] The basics are as follows: Figure 1 , Figure 2 and Figure 3 As shown: a disposable intraoperative dressing collection bag, including an outer package 1, an inner package 7 with several openings sewn on the inner wall of the outer package 1 that are consistent with the outer package 1, both the outer package 1 and the inner package 7 are transparent layers, several skeletons 2 are bonded to the inside of the side wall of the outer package 1 away from the inner package 7, the skeletons 2 extend to the inside of the bottom wall of the outer package 1, and piston assemblies are bonded between the bottom wall of the inner package 7 and the inner bottom wall of the outer package 1.

[0051] The piston assembly includes several inner piston plates 4 and several inner piston cylinders 3. The upper surface of the inner piston plates 4 is bonded to the bottom wall of the inner casing 7. The outer peripheral sidewalls of the inner piston plates 4 are slidably connected to the inner piston cylinders 3. The bottom wall of the inner piston cylinders 3 is bonded to the skeleton 2 inside the bottom wall of the outer casing 1. The side of the inner piston cylinders 3 closest to the side wall of the outer casing 1 is connected to an indicator piston cylinder 5. The indicator piston cylinders 5 are embedded inside the side wall of the outer casing 1 and extend upward. The outer surface of the indicator piston cylinders 5 is engraved with indicator scales 13 and warning lines 14. The indicator piston plates 6 are slidably connected inside the indicator piston cylinders 5. The outer wall of the indicator piston cylinders 5 is a transparent layer. The piston cylinders between the inner piston plates 4 and the indicator piston plates 6 are filled with fluid.

[0052] The top of the inner wall of the outer packaging 1 is sewn with Velcro 9, and the top of the inner wall of the inner packaging 7 is equipped with zippers 11. The top of the outer wall of the outer packaging 1 away from the inner packaging 7 is glued with adhesive tape 10, and release paper is attached to the adhesive tape 10. A label holder 12 is bolted to one side of the outer wall of the outer packaging 1, and label stickers are placed inside the label holder 12. A handle 8 is glued to the top of the outer wall of the outer packaging 1.

[0053] The specific implementation process is as follows: During the operation, medical staff need to collect the used gauze, cotton balls and cut tissue at any time to prevent contamination of the table surface. The release paper on the outer adhesive tape 10 is peeled off and attached to one side of the table surface or surgical drape to avoid occupying table space and enhance the flexibility of the collection bag.

[0054] After the outer package 1 is attached, medical staff can peel off the Velcro 9 to open it and sort the waste into the inner package 7. The inner package 7 is then closed with the zipper 11 to prevent moisture evaporation and leakage. At this point, the weight of the contents in each inner package 7 is not uniform. The contents of each individual inner package 7 press down the inner package piston plate 4, pushing the fluid in the inner package piston cylinder 3 supported by the frame 2 downwards into the indicator piston cylinder 5, which in turn pushes the indicator piston plate 6 upwards. The contents of the inner package 7 can be identified through the scale 13 engraved on the outer wall of the transparent indicator piston cylinder 5. The weight of the contents is indicated by the warning line 14 engraved on the piston cylinder 5, which is a preset overflow warning. This is to warn that gauze and cotton balls weighing more than this warning line 14 may overflow wastewater when the inner pack 7 is closed, contaminating the outer pack 1 and the work surface. After the waste is filled in the inner pack 7, medical staff can close the inner pack 7 with the Velcro 9 to reduce internal and external contamination. The specific contents name is written on the label and affixed to the top of the inner pack 7 for easy identification of the contents during subsequent handling. The date, number, etc. can also be written on the label and affixed to the outer pack 1 to indicate surgical information.

[0055] After the surgery, medical staff close the inner package 7 and the outer package 1, peel off the adhesive tape 10, and use the handle 8 to easily transfer and recycle surgical waste, reducing the possibility of contamination caused by accidental errors.
