Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically a multifunctional dressing tray. Background Technology

[0002] In medical procedures, dressing trays are core medical devices for nurses and doctors to perform wound care, injections, and other procedures. Their suitability directly affects treatment efficiency and aseptic protection. While existing dressing trays can fulfill basic instrument storage functions, with the increasing demands for standardized operations, aseptic techniques, and convenience in clinical practice, traditional products are gradually revealing numerous inadequacies in their adaptability. Most dressing trays lack a stable support structure, making them prone to tipping over on uneven surfaces, and their poor anti-slip properties affect operational safety. Furthermore, their fixed and rigid internal compartment designs make it difficult to flexibly adjust to accommodate different sizes of medical consumables, leading to disorganized placement of items such as test tubes, cotton swabs, and syringes, and resulting in low retrieval efficiency.

[0003] Furthermore, traditional dressing trays often have fixed or simple snap-fit ​​inner boxes, making removal, cleaning, and replacement cumbersome. The lack of effective separation between medical waste and clean supplies increases the risk of cross-contamination. While some products have lids, their sealing performance is insufficient, failing to effectively prevent external dust and liquids from entering. They also lack a visual design, making it difficult to quickly check the contents. During transport, the inner box is prone to slipping, further reducing reliability and limiting the practical value of dressing trays in clinical settings. Utility Model Content

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Example Please see Figure 1-7 This utility model provides a technical solution: a multifunctional dressing tray, including a sterile box body 100, with adjustable anti-slip support feet 110 fixedly installed at the four corners of the bottom of the sterile box body 100, a pull-out guide rail 120 provided on the inner side wall of the sterile box body 100, an inner box 200 slidably connected to the pull-out guide rail 120, a box cover 300 rotatably connected to one side of the sterile box body 100 via a hinge 130, the inner box 200 is divided into a test tube placement chamber 210, a consumable storage chamber 220 and a medical waste chamber 230 by a partition, and a snap-lock 140 is installed between the box cover 300 and the sterile box body 100; The hinge 130 is provided with a damping adjustment mechanism 400 for controlling the opening and closing angle of the cover 300 and achieving the limit. The damping adjustment mechanism 400 includes a threaded hole 410 opened on the outside of the sleeve of the hinge 130. An adjusting screw 420 is threadedly connected inside the threaded hole 410. One end of the adjusting screw 420 is fixedly connected to a friction block 430. The surface of the friction block 430 is provided with a plurality of friction protrusions 431. The friction protrusions 431 are in frictional contact with a friction ring 440 fixedly sleeved on the hinge 130 shaft.

[0018] Specifically, when a nurse is preparing to perform wound dressing changes or injections in the treatment room or ward, the multi-functional dressing tray should first be placed on the work surface. If the work surface is slightly uneven, the tray can be kept stable by adjusting the adjustable non-slip support feet 110 at the four corners of the bottom of the sterile box 100, so as to avoid the items from tipping over due to the tilt of the tray during subsequent operations. After the tray is stable, the nurse can flip the lid 300 upward and rotate it around the hinge 130. After opening the lid 300, the nurse can pull the inner box 200 outward along the pull-out guide rail 120 on the inner side wall of the sterile box 100. The pull-out guide rail 120 allows the inner box 200 to slide out smoothly, making it convenient for the nurse to quickly store and retrieve items. At this point, the nurse can place the test tubes needed for dressing change one by one into the test tube placement chamber 210 of the inner box 200, and put clean consumables such as cotton swabs, bandages, and syringes into the consumable storage chamber 220. At the same time, medical waste such as used cotton swabs and needle caps generated during the operation should be disposed of in the medical waste chamber 230 in a timely manner. Through the physical separation of the three chambers, cross-contamination between clean consumables and medical waste is effectively avoided. When the operation is over or the dressing tray needs to be transferred, the inner box 200 is pushed back into the sterile box body 100 along the pull-out guide rail 120, and then the box lid 300 is flipped over and closed. The locking lock 140 between the box lid 300 and the sterile box body 100 is fastened to ensure that the box lid 300 will not be accidentally opened during transportation, protecting the internal items from external dust or liquid contamination, and effectively adapting to the needs of clinical sterile operation.

[0019] After opening the lid 300, the nurse can adjust the opening angle of the lid 300 and limit it by using the damping adjustment mechanism 400 on the hinge 130, according to the actual needs such as operating space and ease of access. Specifically, the adjusting screw 420 can be rotated clockwise to push it inward along the threaded hole 410 and push the friction block 430 closer to the friction ring 440. By increasing the contact pressure between the friction protrusion 431 and the friction ring 440, the sliding friction is increased, allowing the lid 300 to be stably maintained at a suitable angle for rotation and stopping, avoiding the impact of the lid closing on itself or over-flipping on the handling of items during operation. If it is necessary to quickly adjust the lid angle or close it smoothly, the adjusting screw 420 can be rotated counterclockwise to reduce the friction, making the rotation of the lid 300 more flexible, taking into account both the stability and convenience of clinical operation.

[0020] In this embodiment: the adjustable anti-slip support foot 110 includes a support column 111 threadedly connected to the sterile box body 100, a silicone pad 112 fixedly attached to the bottom of the support column 111, a diamond-shaped anti-slip texture 113 on the bottom of the silicone pad 112, and a hexagonal adjustment knob 114 on the top of the support column 111.

[0021] Specifically, when using a multi-functional dressing tray in clinical settings, if the work surface is uneven, nurses can adjust the stability of the sterile box body 100 using the adjustable anti-slip support feet 110. First, use your fingers or a tool to turn the hexagonal adjustment knob 114 on the top of the support column 111. Since the support column 111 and the sterile box body 100 are connected by threads, rotating the hexagonal adjustment knob 114 will cause the support column 111 to rise and fall along the thread direction until the sterile box body 100 is level. At this time, the silicone pad 112 at the bottom of the support column 111 will be in close contact with the work surface. The silicone pad 112 itself has good anti-slip properties, and together with the diamond-shaped anti-slip texture 113 on its bottom, it can greatly increase the friction with the work surface. Even if the nurse performs actions such as picking up and putting down consumables or operating instruments on the dressing tray, the sterile box body 100 can be prevented from sliding, further improving the safety and stability of the operation process and solving the problem that traditional dressing trays are prone to tipping over on uneven work surfaces.

[0022] In this embodiment: a handle 310 is fixedly installed on the top of the box cover 300, a transparent plastic box 320 is embedded on the surface of the box cover 300, and a plastic box cover 330 is hinged to the transparent plastic box 320.

[0023] Specifically, when a nurse needs to move the dressing tray from the treatment room to the ward, they can hold the handle 310 on the top of the lid 300 with one or both hands. The size and position of the handle 310 are adapted to hand grip habits, making it easy to exert force and move, avoiding potential contamination or slippage from direct contact with the sterile box body 100. Upon arrival at the ward, when the nurse needs to verify the patient's name, bed number, dressing site, or confirm the consumables list such as the required number of cotton swabs and test tube specifications, they can flip the plastic box lid 330 upwards. Because the plastic box lid 330 is hinged to the transparent plastic box 320, the flipping process is flexible and easy to open. Afterwards, the patient information card or consumable list card stored inside the transparent plastic box 320 can be directly seen without opening the entire box lid 300, reducing the number of times the internal sterile environment comes into contact with the outside world. After verification, the card is placed back into the transparent plastic box 320, and then the plastic box lid 330 is flipped down to close. The plastic box lid 330 can protect the card from dust or disinfectant contamination, ensuring that the information is clearly identifiable. At the same time, the visual design of the transparent plastic box 320 also allows nurses to quickly confirm whether the items are complete before operation, avoiding operation delays caused by untimely information verification and improving clinical work efficiency.

[0024] In this embodiment: the pull-out guide rail 120 includes a guide rail body 121 fixed to the inner wall of the sterile box body 100. A ball slider 122 is provided on the inner side of the guide rail body 121. The ball slider 122 is fixedly connected to the outer wall of the inner box 200. An anti-detachment buckle 123 is provided at the end of the guide rail body 121. A positioning groove 201 adapted to the anti-detachment buckle 123 is provided on the outer wall of the inner box 200.

[0025] Specifically, when a nurse needs to store or retrieve consumables into the inner box 200, they simply pull the inner box 200 outwards. The outer wall of the inner box 200 will cause the ball bearing slider 122 to slide along the guide rail body 121. Since the guide rail body 121 is fixed to the inner wall of the sterile box body 100, it provides a stable sliding path for the ball bearing slider 122. The balls inside the ball bearing slider 122 can convert sliding friction into rolling friction, greatly reducing the resistance when pulling the inner box 200 out, allowing the nurse to easily complete the pulling action and avoiding the problem of difficult retrieval of traditional fixed or simple snap-fit ​​inner boxes. When the inner box 200 is pulled out to its maximum stroke, the anti-detachment buckle 123 at the end of the guide rail body 121 will engage. The inner box 200 automatically engages with the positioning groove 201 on the outer wall of the inner box 200, forming a mechanical limit to prevent the inner box 200 from slipping out of the sterile box body 100 due to excessive force by the nurse, thus avoiding damage or contamination of the internal consumables. After the consumables have been stored or removed, the nurse only needs to gently push the inner box 200 inward. The inner box 200 drives the ball slider 122 to slide in the opposite direction. At this time, the anti-slip buckle 123 will disengage from the positioning groove 201 under the pushing force until the inner box 200 is completely pushed back into the sterile box body 100. The whole process ensures the smoothness of the pull-out and improves the safety of use through the anti-slip structure, which is suitable for the high-frequency clinical needs of retrieving the inner box 200.

[0026] In this embodiment: a multi-layer elastic clamping plate 211 is fixedly installed inside the test tube placement cavity 210. The elastic clamping plate 211 is made of medical rubber material, and the surface of the multiple elastic clamping plates 211 is provided with stepped holes 212 adapted to different test tube diameters. A sponge buffer layer 213 is provided at the bottom of the test tube placement cavity 210.

[0027] Specifically, when nurses need to store test tubes containing disinfectant, saline solution, or patient samples, they can select the corresponding stepped hole 212 on the elastic clamping plate 211 inside the test tube placement cavity 210 according to the diameter of the test tube. Because the elastic clamping plate 211 is made of medical-grade rubber, it has good elasticity and toughness. When the test tube is inserted into the stepped hole 212, the elastic clamping plate 211 will generate an inward clamping force due to its own elasticity, firmly fixing the test tube and preventing it from shaking during handling or operation. At the same time, the different hole diameters of the stepped hole 212 can accommodate common 10ml and 20ml test tubes. Different sizes of test tubes, such as 10ml and 50ml, eliminate the need for multiple test tube racks, reducing the space occupied by medical equipment. The sponge buffer layer 213 at the bottom of the test tube placement cavity 210 provides soft support for the bottom of the test tube. When the test tube is inserted to the bottom, the bottom of the test tube will contact the sponge buffer layer 213, avoiding hard contact that could cause the test tube to break. During the transfer of the dressing tray, the sponge buffer layer 213 can also absorb the impact force generated by vibration, further protecting the test tube and the internal liquid. This solves the problem of test tubes being easily damaged by collisions when stored in traditional dressing trays, improving the safety and compatibility of test tube storage.

[0028] In this embodiment: a flip-type partition plate 221 is provided inside the consumable storage cavity 220. One side of the flip-type partition plate 221 is rotatably connected to the inner wall of the consumable storage cavity 220 through a rotating shaft 222. A magnetic positioning block 223 is provided on the other side of the flip-type partition plate 221. A metal sheet 224 adapted to the magnetic positioning block 223 is provided on the inner wall of the consumable storage cavity 220. A plurality of consumable hanging rings 225 are fixedly provided on the inner side of the flip-type partition plate 221.

[0029] Specifically, when nurses need to store consumables of different specifications such as tourniquets, scissors, forceps, and small gauze rolls, they can adjust the angle of the flip-type partition 221 according to the size and quantity of the consumables. Since one side of the flip-type partition 221 is connected to the inner wall of the consumable storage cavity 220 via a damping pivot 222, the nurse only needs to gently turn the flip-type partition 221 to achieve a 0-90 degree flip around the pivot 222. When flipped to the appropriate angle, the flip-type partition 221 can be stood up to facilitate medical staff to take out the consumables in the box. The magnetic positioning block 223 on the other side of the flip-type partition 221 will adhere to the metal sheet 224 on the inner wall of the consumable storage cavity 220. The magnetic force will achieve stable positioning of the flip-type partition 221 and prevent it from rotating on its own during transportation. At the same time, the multiple consumable hanging rings 225 fixed inside the flip-type partition 221 can be used to hang long strips or consumables with hanging holes such as tourniquets and small tweezers, so that the consumables can be stored in a hanging manner. This will not only avoid the inconvenience of stacking with other consumables, but also keep the consumables dry and clean.

[0030] In this embodiment: a self-sealing garbage bag 231 is detachably fitted inside the medical waste chamber 230. The opening edge of the self-sealing garbage bag 231 is provided with a pull-out sealing rope 232. An elastic pressure ring 233 is snapped into the opening of the medical waste chamber 230. After the elastic pressure ring 233 covers the opening of the medical waste chamber 230, it presses and fixes the opening of the self-sealing garbage bag 231.

[0031] Specifically, before the dressing change procedure begins, the nurse first inserts the self-sealing garbage bag 231 into the medical waste chamber 230, making the opening edge of the self-sealing garbage bag 231 fold outwards to fit the opening of the medical waste chamber 230. Then, the elastic pressure ring 233 is fastened to the opening of the medical waste chamber 230. The elastic pressure ring 233 has a certain elasticity, and after being fastened, it will generate a uniform pressing force on the opening edge of the self-sealing garbage bag 231, firmly fixing it to the medical waste chamber 230, preventing the self-sealing garbage bag 231 from slipping off during the operation and causing garbage to leak out. During dressing changes, medical waste generated can be disposed of by nurses in the self-sealing garbage bag 231 within the medical waste chamber 230 at any time. This eliminates the need for frequent waste disposal and reduces contact with the waste. When the self-sealing garbage bag 231 is full, the nurse can first remove the elastic sealing ring 233, then pinch the pull-out sealing rope 232 at the opening of the self-sealing garbage bag 231 and pull it to both sides to seal the self-sealing garbage bag 231, preventing liquid leakage or odor spread. After sealing, the self-sealing garbage bag 231 is removed from the medical waste chamber 230 and disposed of according to medical waste disposal procedures. A new self-sealing garbage bag 231 is then inserted and the elastic sealing ring 233 is re-locked. The entire process is simple and effectively prevents medical waste from contacting the outside environment, reducing the risk of cross-contamination and complying with clinical aseptic operation standards.

[0032] In this embodiment: the outer wall of the sterile box body 100 is provided with an arc-shaped moving groove 150, the inner side of the arc-shaped moving groove 150 is provided with an anti-slip rubber pad 151, and the inside of the sterile box body 100 is provided with a sealing strip 160, which is embedded and connected to the opening of the inner box 200.

[0033] Specifically, when a nurse needs to carry the multi-functional dressing tray with both hands, she can insert her fingers into the arc-shaped moving grooves 150 on both sides of the sterile box body 100. The arc of the moving grooves 150 is adapted to the curvature of the fingers and conforms to the contour of the hand, making it easier to exert force. At the same time, the anti-slip rubber pads 151 on the inner side of the arc-shaped moving grooves 150 can increase the friction between the fingers and the sterile box body 100, preventing the dressing tray from slipping and falling off during carrying even if the hands are wet with disinfectant or slightly sweaty, thus improving the stability of carrying with both hands; the sealing strip 160 inside the sterile box body 100 is located on the lid. After the lid 300 is closed and the latch 140 is fastened, it will fit tightly with the edge of the inner box 200. The sealing strip 160 has good sealing and elasticity, which can fill the gap between the sterile box body 100 and the inner box 200, effectively preventing dust, droplets and liquids such as disinfectant and saline that may splash during operation from entering the inner box 200. This protects the clean consumables inside the inner box 200 in a sterile environment. At the same time, the sealing strip 160 can also reduce the collision and friction between the inner box 200 and the sterile box body 100, extending the service life of the instrument.
