Description

Technical Field

[0001] This utility model relates to the field of medical care technology, and in particular to a medical tape cutting device that is easy to use. Background Technology

[0002] Medical adhesive tape is an indispensable tool in medical procedures, widely used for fixing dressings, protecting wounds, and assisting with medical device procedures. However, current medical adhesive tape requires one hand to press down on the applicator to secure the tape, while the other hand catches the cut tape. This process is cumbersome and inconvenient for single-handed clinical use. This is particularly problematic when healthcare workers are using nursing carts for dressing changes, significantly reducing nursing efficiency.

[0003] To address this existing problem, designs with downward-facing cutting serrations have emerged on the market, such as a medical tape fixing and cutting device with publication number CN221331679U. This device uses a fixed crossbeam between the tape outlet and the cutting serrations, with the sharp ends of the serrations pointing downwards. During use, the tape can be cut simply by lifting the hand upwards, facilitating one-handed operation in clinical use. However, this solution still has shortcomings. First, after the tape is torn, the cut end is located at the cutting serrations, making it inconvenient to remove the cut tape for subsequent uses. Second, because the tape is located at the cutting serrations, there is still a risk of finger cuts during handling, potentially leading to medical infections and exposing healthcare workers to a hazardous environment. Therefore, further improvements and optimizations to the cutting device are needed. Utility Model Content

[0004] This invention provides an easy-to-use medical tape cutting device to solve the above-mentioned technical problems.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A medical tape cutting device for easy access includes a receiving box and a roll of tape. The roll of tape is positioned in the receiving box via a positioning crossbar. The front of the receiving box has an opening for pulling out the roll of tape. The upper surface of the opening has vertically downward cutting serrations. The receiving box also has a movable stop bar positioned below the positioning crossbar and the cutting serrations. Both ends of the movable stop bar are connected to the inner wall of the receiving box via a rotating shaft. A torsion spring is mounted on the rotating shaft. One end of the torsion spring is fixed to the rotating shaft, and the other end of the torsion spring is engaged with the inner wall of the receiving box.

[0007] Furthermore, the rotating shaft includes a first connecting part and a second connecting part, which are fixedly connected to form an L-shaped structure. The inner wall of the receiving box is provided with an insertion hole for the first connecting part to be inserted. The first connecting part is rotatably connected to the insertion hole, and the second connecting part is fixedly connected to the end face of the movable stop lever. When the movable stop lever is turned upwards, the movable stop lever rotates about the first connecting part as its original axis of rotation.

[0008] Furthermore, a limiting block is provided on the inner side wall of the receiving box, and the limiting block is disposed adjacent to the first connecting part. The limiting block is used to fix one end of the torsion spring, and when the external force is lost, it can cause the second connecting part to return to its original position, that is, the movable stop lever returns to its original position.

[0009] Furthermore, the torsion spring is sleeved on the first connecting part, and the second connecting part is provided with a fixing block for the end of the torsion spring to engage. The other end of the torsion spring is fixedly installed on the fixing block. When the second connecting part is rotated, the second connecting part and the torsion spring form a rotational force arm, causing the torsion spring to twist and store elastic potential energy. After release, the torsion spring returns to its original state.

[0010] Furthermore, one end of the torsion spring is inserted into the fixed insert, and the other end of the torsion spring is fixedly connected to the limiting block. By pulling the tape roll upward, the tape roll wraps around the movable stop bar, forming an upward pulling force. At this time, the movable stop bar will be pulled upward until the tape roll is pulled to the cutting teeth, where it is cut. After cutting, the tape roll at the break point loses the external force, and the movable stop bar springs back downward. Since a portion of the tape roll is pulled out from the pulling end, this section of tape will hang down with the movable stop bar, i.e., it will be located at the movable stop bar. At this time, the break point of the tape roll is away from the cutting teeth, making it easy to retrieve next time.

[0011] Furthermore, the second connecting part is set at a 45° angle to the bottom surface of the receiving box. When the torsion spring returns to its natural state, the second connecting part is at a 45° angle to the bottom surface of the receiving box. This facilitates a downward traction force on the tape roll. When cutting the tape, the tension at both ends makes it easier for the cutting saw teeth to cut and separate the tape, ensuring the cutting effect.

[0012] Furthermore, a cover plate is hinged to the top surface of the receiving box, and a handle is provided on the cover plate. The hinged design of the cover plate facilitates opening and closing; the receiving box can be quickly opened or closed by rotating the cover plate, making it easy to insert the tape roll. The handle provides convenient gripping and operation; the cover plate can be pulled by hand for operation.

[0013] Furthermore, a hanging part is provided on the back of the container. The hanging part facilitates hanging the container on a wall, instrument rack, or nursing cart, saving work surface space.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. This utility model allows for the cutting of adhesive tape by pulling the tape roll upwards, ensuring the convenience of one-handed operation for medical staff and improving nursing efficiency;

[0016] 2. After cutting, the cut end of the tape roll is pushed downward by the return of the movable stop lever, making it easy to use next time.

[0017] 3. This utility model places the cut end of the adhesive tape away from the cutting serrations, ensuring that medical staff will not touch the cutting serrations during use and guaranteeing their safety. Attached Figure Description

Detailed Implementation

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings. The illustrative embodiments and descriptions of this utility model are only used to explain this utility model and are not intended to limit this utility model.

[0023] Example 1

[0024] like Figure 1-3As shown, this utility model discloses an easy-to-use medical tape cutting device, including a receiving box 1 and a tape roll 2. The tape roll 2 is set in the receiving box 1 by a positioning crossbar 3. The front of the receiving box 1 is provided with an opening 4 for pulling out the tape roll 2. The upper end face of the opening 4 is provided with vertically downward cutting serrations 5. The receiving box 1 is also provided with a movable stop bar 6. The movable stop bar 6 is located below the positioning crossbar 3 and the cutting serrations 5. The two ends of the movable stop bar 6 are connected to the inner side wall of the receiving box 1 by a rotating shaft 7. A torsion spring 8 is provided on the rotating shaft 7. One end of the torsion spring 8 is fixed to the rotating shaft 7, and the other end of the torsion spring 8 is engaged with the inner side wall of the receiving box 1.

[0025] The rotating shaft 7 includes a first connecting part 701 and a second connecting part 702, which are fixedly connected to form an L-shaped structure. Specifically, the inner wall of the housing 1 is provided with an insertion hole for the first connecting part 701 to be inserted. The first connecting part 701 is rotatably connected to the insertion hole, and the second connecting part 702 is fixedly connected to the end face of the movable stop lever 6. When the movable stop lever 6 is turned upward, the movable stop lever 6 rotates about the first connecting part 701 as the original axis of rotation.

[0026] The inner wall of the receiving box 1 is provided with a limiting block 9, which is disposed adjacent to the first connecting part 701. Specifically, the limiting block 9 is used to fix one end of the torsion spring 8, and when the external force is lost, it can cause the second connecting part 702 to return to its original position, that is, the movable stop lever 6 returns to its original position.

[0027] The torsion spring 8 is sleeved on the first connecting part 701, and the second connecting part 702 is provided with a fixing block 10 for the end of the torsion spring 8 to be engaged. Specifically, the other end of the torsion spring 8 is fixedly installed on the fixing block 10. When the second connecting part 702 is rotated, the second connecting part 702 and the torsion spring 8 form a rotational force arm, causing the torsion spring 8 to twist and store elastic potential energy. After release, the torsion spring 8 returns to its original state.

[0028] One end of the torsion spring 8 is inserted into the fixed insert 10, and the other end of the torsion spring 8 is fixedly connected to the limiting block 9. Specifically, by pulling the tape roll 2 upward, the tape roll 2 wraps around the movable stop bar 6, forming an upward pulling force. At this time, the movable stop bar 6 will be pulled upward until the tape roll 2 is pulled to the cutting serration 5, where it is cut. After cutting, the tape roll 2 at the break point loses the external force, and the movable stop bar 6 springs back downward. Since a portion of the tape is pulled out from the pulling end of the tape roll 2, this section of tape will hang down with the movable stop bar 6, that is, it will be located at the movable stop bar 6. At this time, the break point of the tape roll 2 is away from the cutting serration 5, making it easy to retrieve next time.

[0029] The second connecting part 702 is set at a 45° angle to the bottom surface of the receiving box 1. Specifically, when the torsion spring 8 returns to its natural state, the second connecting part 702 is at a 45° angle to the bottom surface of the receiving box 1. This facilitates the tape roll 2 to be subjected to a downward traction force. When cutting the tape, the tension at both ends is more conducive to the cutting saw 5 cutting and separating the tape, ensuring the cutting effect.

[0030] The top surface of the receiving box 1 is hinged to a cover plate 11, and a handle 12 is provided on the cover plate 11. Specifically, the hinged design of the cover plate 11 facilitates opening and closing; the receiving box 1 can be quickly opened or closed by rotating the cover plate 11, facilitating the insertion of the adhesive tape roll 2. The handle 12 provides convenience for gripping and operation; the cover plate 11 can be pulled by hand for operation.

[0031] The back of the housing 1 is provided with a hanging part 13. Specifically, the hanging part 13 facilitates hanging the housing 1 on a wall, instrument rack or nursing treatment cart, saving work surface space.

[0032] Example 2

[0033] Based on Example 1, this example proposes a specific implementation process for an easy-to-use medical tape cutting device.

[0034] The specific implementation principle and process are as follows:

[0035] Place the tape roll 2 on the positioning crossbar 3 and pull the free end of the tape roll 2 to the opening 4. Hold the free end of the tape roll 2 and let it pass over the movable stop bar 6 from the bottom, then pull the tape upwards until the free end of the tape is at the cutting teeth 5. Select a suitable cutting position and pull upwards until the tape contacts the cutting teeth 5. During this process, the movable stop bar 6 is subjected to an upward pulling force, and the second connecting part 702 rotates upwards until it reaches its maximum rotation, at which point the tape is cut. After cutting, the tape roll 2 is no longer subjected to external force, and the free end of the tape roll 2 hangs down naturally. The movable stop bar 6 returns to its original position. At this time, the free end of the tape roll 2 is away from the cutting teeth 5, which is convenient for use and avoids injury from contact with the cutting teeth 5 during operation.

[0036] Of course, there may be other embodiments of this utility model. Without departing from the spirit and essence of this utility model, those skilled in the art can make various corresponding changes and modifications based on this utility model, but these corresponding changes and modifications should all fall within the protection scope of the appended claims of this utility model.
