Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical auxiliary device technology, and in particular to a medical tape tearing device. Background Technology
[0002] In clinical medical care, adhesive tape is an indispensable basic consumable, widely used in scenarios such as fixing needles during intravenous infusions and blood transfusions, securing dressings during wound bandaging, and fixing various catheters. Medical staff need to use adhesive tape dozens or even hundreds of times every day. Especially in emergency situations such as emergency rooms and surgeries, the convenience and efficiency of adhesive tape use directly affect the smooth progress of medical procedures and the patient's treatment experience.
[0003] Currently, the adhesive tape rolls used in clinical practice typically require two-handed operation—one hand to hold the tape roll while the other hand tears it. However, in emergency situations or during busy work hours, medical staff often find it difficult to free up both hands for this task. To cope with emergencies, medical staff often need to tear the tape into appropriate lengths in advance and stick them to their work clothes for later use. However, this practice not only easily leads to tape contamination but also often results in forgetting to prepare in advance due to busy work schedules, leading to chaos when urgently needed. In addition, the edges of manually torn tape are often uneven, affecting both aesthetics and potentially reducing the fixation effect.
[0004] Therefore, existing technologies need to be improved and developed. Utility Model Content

Detailed Implementation
[0025] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention 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 invention, and not all embodiments. Other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are all within the scope of protection of the present invention.
[0026] Please see Figure 1 and Figure 2In one embodiment of this utility model, a medical adhesive tape tearing device is disclosed, including a base 100, on which a support roller 101 is horizontally arranged at the top, the support roller 101 being used to support an adhesive tape roll 130; a support plate 110, disposed on the front of the base 100 and located below the support roller 101, for flattening and supporting the adhesive tape pulled out from the adhesive tape roll 130; the support plate 110 includes a smooth support area 111 near the support roller 101 and a rough adhesion area away from the support roller 101; the smooth support area 111 has a cutting slit 113 whose length direction is parallel to the axial direction of the support roller 101; the surface of the rough adhesion area is provided with an adhesive layer 112, the coefficient of friction of the adhesive layer 112 being greater than that of the support roller 101. The surface friction coefficient of the smooth support area 111; the cutting assembly 120 includes a blade 121 and an operating handle, the blade 121 being slidably disposed within the cutting slit 113, and the operating handle being fixedly connected to the top of the blade 121 and extending in a direction parallel to the support plate 110; the operating handle includes a pressing section 122 located above the adhesive layer 112, the lower surface of the pressing section 122 maintaining sliding contact with the surface of the adhesive layer 112; wherein, when the cutting assembly 120 is driven to slide by the operating handle, while the blade 121 completes the cutting of the adhesive tape, the pressing section 122 continuously presses the adhesive tape onto the surface of the adhesive layer 112, so that the cut adhesive tape segment remains in a stable adhesive state for single-handed tearing.
[0027] In the specific implementation process, the adhesive tape is first pulled out from the tape roll 130 on the support roller 101, and after being flattened by the smooth support area 111 of the support plate 110, the adhesive surface is pressed onto the surface of the adhesive layer 112 in the rough adhesion area. When cutting is required, the blade 121 is slid along the cutting seam 113 by operating the handle with one hand. While the blade 121 is cutting the tape, the pressing section 122 of the operating handle simultaneously presses and fixes the cut tape segment onto the surface of the adhesive layer 112. After the cutting is completed, the cut tape segment remains stably adhered to the adhesive layer 112, and medical staff can directly tear off the tape segment of the required length from the adhesive layer 112 with one hand for use.
[0028] In this embodiment, the support plate 110 smoothly supports the adhesive tape, making cutting smoother. When the operating handle slides to cut, the pressing section 122 simultaneously presses and fixes the cut tape segment onto the adhesive layer 112, allowing for subsequent one-handed tearing. During use, both cutting and subsequent tearing can be completed with just one hand, resulting in a high degree of cut smoothness and simple, efficient operation. This effectively solves the technical problems of traditional adhesive tape use requiring two hands and producing uneven cuts, significantly improving medical work efficiency and operational convenience.
[0029] For example, please refer to Figure 3 , Figure 4 , Figure 5 and Figure 6 The medical tape tearing device further includes a tape lifting assembly 140. The smooth support area 111 has a groove extending along the length of the cutting seam 113 on the side that contacts the tape. At least two top blocks 141 are spaced apart in the groove. An elastic element 142 is provided between the top block 141 and the bottom surface of the groove. When the tape is stretched and adhered to the surface of the adhesive layer 112, the top block 141 is pressed down. When the tape is cut, the elastic element 142 pushes the top block 141 upward, so that the tape in the smooth support area 111 section forms an arch for gripping.
[0030] For specific implementation details, please refer to [link / reference]. Figure 6 When the adhesive tape is stretched and adhered to the surface of the adhesive layer 112, the tension of the tape causes the top block 141 to be pressed down, compressing the elastic element 142 below it so that it is completely submerged in the groove; please refer to Figure 4 After the tape is cut, the tape tension disappears, the elastic element 142 releases its elastic force to push the top block 141 upward, and the top block 141 lifts the tape portion of the smooth support area 111 to form a distinct arch.
[0031] This embodiment provides the operator with a clear gripping position by forming an arched portion, which significantly improves the convenience of one-handed operation. The arched portion creates a gap between the end of the adhesive tape and the surface of the support plate 110, making it easy for fingers to reach in and grip, thus solving the problem of difficulty in gripping flat adhesive tape. The automatic reset characteristic of the elastic element 142 ensures that the arched portion can be reliably formed after each cut, while avoiding interference with the tape cutting process.
[0032] For example, please refer to Figure 2 The top of the smooth support area 111 is provided with a pressure strip 114. The pressure strip 114 includes connecting parts at both ends and a pressing part in the middle. The connecting parts are fixedly connected to the surface of the smooth support area 111. A guide gap for the adhesive tape to pass through is formed between the pressing part and the surface of the smooth support area 111. The pressing part presses the passing adhesive tape onto the surface of the smooth support area 111, so that the adhesive tape remains flat.
[0033] In the specific implementation process, the adhesive tape is first pulled out from the adhesive tape roll 130 on the support roller 101. When the adhesive tape passes through the guide gap of the pressure strip 114, it is evenly pressed onto the surface of the smooth support area 111 by the pressing part. At the same time, the other end of the adhesive tape is firmly attached to the adhesive layer 112 of the rough adhesion area. This double-end fixing method ensures that the adhesive tape remains flat and stretched throughout the process. When cutting is required, the single-handed operation handle drives the blade 121 to slide along the cutting seam 113. While the blade 121 is cutting the adhesive tape, the pressing section 1 of the operating handle is also engaged. 22 Simultaneously, the cut tape segment is continuously pressed and fixed onto the surface of the adhesive layer 112; after the cutting is completed, the tension of the tape disappears, and the elastic element 142 of the lifting component 140 pushes the top block 141 upward, so that the tape segment of the smooth support area 111 forms an arched part that is easy to grasp. At this time, medical staff can directly tear off the tape segment of the required length from the adhesive layer 112 with one hand, realizing a convenient operation process of cutting with one hand and taking it out at any time with one hand. The tape remains flat throughout the process, the cut is neat, and the operation is simple and efficient.
[0034] For example, the base 100 includes a storage cabinet 102 and a support frame 103 fixed to the top of the storage cabinet 102. The support roller 101 is horizontally arranged on the support frame 103. The storage cabinet 102 has an opening on its side, and the opening has an openable cabinet door that cooperates with the opening. The support plate 110 is rotatably connected to the top front of the storage cabinet 102 through a connecting shaft and a locking member 1022. In this embodiment, the base 100 adopts an integrated design of the storage cabinet 102 and the support frame 103. The storage cabinet 102 has an access opening with an openable cabinet door on its side. The cabinet door adopts a sealed design and can be used to classify and store medical supplies such as spare adhesive tape rolls 130 and scissors of different specifications, realizing the dual functions of adhesive tape tearing and material storage.
[0035] For example, please refer to Figure 2 The support plate 110 has connecting shafts on both sides of the smooth support area 111; the storage cabinet 102 has connecting parts on both sides of the top front, and the connecting parts have connecting holes 1021 and locking holes. The connecting shafts are located in the connecting holes 1021; the locking holes have internal threads; the locking member 1022 is screwed into the locking hole; the end of the locking member 1022 can press against the side of the smooth support area 111 to fix its tilt angle.
[0036] In the specific implementation process, when it is necessary to adjust the tilt angle of the support plate 110, first loosen the locking member 1022 so that its end is removed from the pressure on the side of the smooth support area 111. At this time, the support plate 110 can rotate freely around the connecting shaft in the connecting hole 1021. After adjusting to the required operating angle, tighten the locking member 1022 again so that its end radially presses against the side of the smooth support area 111 to generate frictional locking force, thereby fixing the position of the support plate 110.
[0037] This embodiment, by setting an adjustable angle mechanism, allows medical staff to freely adjust the tilt angle of the support plate 110 within the range of 0°-90° according to their operating habits and work scenario requirements, so as to obtain the best operating field of vision and force application angle; and when used in a confined space, the angle can be adjusted to save operating space, while in regular use, the angle can be adjusted to a larger angle for easy observation, making it suitable for different application scenarios; the locking component 1022 adopts a progressive locking design, which can ensure stability during operation and is easy to adjust.
[0038] For example, the support roller 101 is provided with at least one axial limiting component 104, the axial limiting component 104 including a clamping member detachably clamped on the support roller 101; the clamping member has an arc-shaped clamping portion that matches the outer diameter of the support roller 101; the clamping member is fixed on the support roller 101 by an elastic clamping force to limit the axial displacement of the adhesive tape roll 130.
[0039] In the specific implementation process, multiple rolls of adhesive tape 130 can be set on the support roller 101 at the same time. According to the width and number of rolls of adhesive tape 130, the clamping member is slid along the axial direction of the support roller 101 to a predetermined position, and the elastic clamping force between its arc-shaped clamping part and the support roller 101 is used to achieve rapid positioning. Each clamping member is fixed independently, and a space for accommodating rolls of adhesive tape 130 is formed between adjacent clamping members, which effectively prevents axial movement when multiple rolls of adhesive tape are used at the same time.
[0040] This embodiment achieves a flexible configuration with multiple uses by setting up a clamping component, which can simultaneously load 2-4 rolls of medical tape of different specifications to meet diverse clinical needs; the clamping component adopts an elastic buckle design, which can be loaded and unloaded by hand without tools, making it easy to quickly replace the tape roll 130; the axial position of each tape roll 130 can be adjusted independently to adapt to the mixed loading needs of tape rolls 130 of different widths, thereby improving the efficiency of the device and the space utilization rate.
[0041] For example, the adhesive layer 112 is connected to the support plate 110 by a detachable structure, which includes one of a snap-fit structure, a magnetic adsorption structure, or a hook and loop fastener structure.
[0042] In the specific implementation process, when a snap-fit structure is used, the snap-fit protrusion on the back of the adhesive layer 112 is aligned with the slot on the support plate 110 and pressed to lock it in place; when a magnetic adsorption structure is used, the adhesive layer 112 with magnetic material is brought close to the iron substrate of the support plate 110 and automatically adsorbed and fixed; if a hook and loop fastener structure is used, the hook or rough surface on the back of the adhesive layer 112 is pressed against the corresponding surface on the support plate 110 to complete the connection.
[0043] The detachable design of this embodiment facilitates the periodic replacement of the adhesive layer 112, which may become less tacky due to long-term use, ensuring consistent tape fixation. A dedicated adhesive layer 112 with a matching coefficient of friction can be quickly replaced according to different tape types (such as PE tape, cloth-based tape, etc.). During cleaning and maintenance, the adhesive layer 112 can be removed separately for cleaning or disinfection, maintaining the hygiene of the device. This ensures operational reliability while improving the device's economy and applicability.
[0044] For example, the adhesive layer 112 includes a silicone layer or a polyurethane layer with a microstructure texture, the microstructure texture including regularly arranged protrusions or pits.
[0045] The silicone layer boasts excellent biocompatibility and chemical resistance. Its regularly patterned array of raised bumps ensures reliable adhesion of the adhesive tape while facilitating one-handed removal. The polyurethane layer offers superior mechanical strength and abrasion resistance. Its honeycomb-like pitted structure creates moderate adhesion, ensuring the tape remains stable after cutting and preventing detachment. Both materials are flexible, adaptable to different tape thicknesses, and their surface textures are achieved through precision molding. This combination balances the conflicting requirements of adhesion and tearability; alcohol resistance meets the sterilization requirements of medical environments; and significantly improves the reliability and lifespan of the device.
[0046] For example, the surface smoothing layer of the smooth support area 111 includes one of a polytetrafluoroethylene layer, a silicone rubber layer, or an ultra-high molecular weight polyethylene layer.
[0047] Polytetrafluoroethylene (PTFE), with its extremely low coefficient of friction, ensures smooth and non-sticky sliding of the adhesive tape; silicone rubber combines flexibility with moderate frictional properties, adapting to the flatness requirements of various adhesive tapes; and ultra-high molecular weight polyethylene (UHMWPE) exhibits excellent abrasion resistance, guaranteeing long-term reliability. These materials share the characteristic of ideal surface energy properties, effectively preventing adhesive residue on the tape while withstanding routine medical sterilization processes. Their carefully designed surface microstructure reduces frictional resistance while ensuring flatness and stability during tape delivery.
[0048] In summary, the medical tape tearing device of this embodiment includes a base 100, a support plate 110, and a cutting assembly 120. A horizontal support roller 101 is provided at the top of the base 100 to support the tape roll 130. The support plate 110 is located on the front of the base 100 and below the support roller 101. It includes a smooth support area 111 near the support roller 101 and a rough adhesion area away from the support roller 101. The smooth support area 111 has a cutting slit 113 parallel to the axial direction of the support roller 101, and the surface of the rough adhesion area has an adhesive layer 112 with a high coefficient of friction. The cutting assembly 120 includes a blade 121 slidably disposed within the cutting slit 113 and an operating handle. The operating handle has a pressing section 122 that maintains sliding contact with the surface of the adhesive layer 112. This utility model uses a support plate 110 to flatten and support the adhesive tape, making the cutting smoother. When the operating handle slides to cut, the pressing section 122 simultaneously presses and fixes the cut adhesive tape segment onto the adhesive layer 112, so that it can be torn off with one hand later. When in use, only one hand is needed to complete the two actions of cutting and subsequent tearing. The cut is highly flat and the operation is simple and efficient.
