Description

Technical Field

[0001] This utility model belongs to the field of medical device technology, and in particular relates to a programmable length control medical tape cutting and fixing device and its control system. Background Technology

[0002] Medical tape has a wide range of applications in the medical and health field, such as for attaching and fixing medical supplies like infusion catheters, needles, and wound dressings. Since medical tape is usually sold in rolls, medical personnel need to cut it to different lengths depending on the type of medical supply being fixed. However, manual cutting is time-consuming, labor-intensive, and lacks precise size control; it can also lead to the tape becoming contaminated with germs during the cutting process, necessitating a solution. The invention patent—an automatic medical tape cutter (CN112758747A)—can grip and cut medical tape simultaneously, and is an automatically sterilizable medical tape cutter that can be adapted to different usage needs. However, this patent does not allow for free setting of the tape cutting length, and medical tapes are all pressure-sensitive tapes, which need to be pressed to ensure sufficient adhesive strength. This device does not have an auxiliary pressing device and cannot be used for pressing and cutting pressure-sensitive tapes. Therefore, based on the above problems, designing a medical tape cutting and fixing device with programmable control of length is a technical problem that urgently needs to be solved in this field. Utility Model Content

[0003] The purpose of this invention is to provide a method for precisely cutting medical tape to different lengths, and to apply pressure to the tape using an attached clamping structure to ensure the tape's adhesion effect. This addresses the shortcomings of the prior art, where medical personnel often find it difficult to precisely control the cutting length of medical tape and cannot effectively clamp it.

[0004] The technical solution adopted by this utility model to solve this problem is:

[0005] A programmable length controllable medical tape cutting and fixing device includes a cutting housing containing medical tape, a tape fixing structure for holding the medical tape, a tape outlet for outputting a strip of medical tape, and a rolling guide structure disposed between the two for guiding the strip of medical tape from the medical tape side to the tape outlet side. The tape outlet is provided with a cutting structure for cutting the strip of medical tape and a pressing structure for pressing the strip of medical tape.

[0006] In the above technical solution, the sheared shell includes a front cover and a rear shell assembled as one piece.

[0007] In the above technical solution, the shearing shell is divided into a tape fixing area, a tape guiding area, a tape outlet area, and a handle area. The tape guiding area is located between the tape fixing area and the tape outlet area and is connected to each other.

[0008] In the above technical solution, the tape fixing structure includes a tape fixing wheel disposed within the tape fixing area. The tape fixing wheel is rotatably connected to the rear shell of the shearing housing via its axle. The front side of the tape fixing wheel is provided with a clamping claw for clamping medical tape.

[0009] In the above technical solution, the clamping structure includes a clamping roller disposed outside the tape outlet, which can clamp the tape onto the medical supplies. The clamping roller is mounted on the outside of the shear housing via clamping brackets. Specifically, the clamping roller is fixed to the shear housing outside the tape outlet via two clamping brackets. The clamping brackets are fixed to the shear housing via threads. The clamping brackets contain replaceable springs, and the downward pressure of the clamping roller can be adjusted by replacing the springs.

[0010] In the above technical solution, the rolling guide structure includes a rolling guide track disposed within the belt guide area, a power roller and a driven roller for driving the rolling guide track to roll, and the power roller is driven by a first motor.

[0011] In the above technical solution, the rolling guide track extends along the length of the belt guide area. One end of the rolling guide track is close to the belt fixing wheel, and the other end is close to the cutting structure. The rolling guide track is a rubber track. The surface of the rolling guide track is provided with irregular stripes in the same direction of travel. The rolling guide track uses irregular vertical stripes to reduce the impact on the adhesion of the medical tape.

[0012] In the above technical solution, the cutting structure is a rotating blade structure or a scissor structure.

[0013] In the above technical solution, when the cutting structure is a rotating blade structure, the cutting structure includes a wedge-shaped blade extending along the width direction of the tape guiding area and a cutting shaft. The wedge-shaped blade is rotatably connected to the rear shell of the shearing housing through the cutting shaft, and the cutting shaft is driven by a second motor.

[0014] In the above technical solution, a supporting cutting structure is also provided inside the shearing shell. The supporting cutting structure is fixed on the rear shell of the shearing shell and is arranged opposite to the wedge blade.

[0015] In the above technical solution, when the cutting structure is a scissor-type structure, the cutting structure includes a scissor-type blade extending along the width direction of the tape guiding area and a control arm. The scissor-type blade is connected to the shearing housing through a connecting shaft, and the control arm is driven and controlled by a second motor to drive the scissor-type blade to cut the tape.

[0016] The above technical solution also includes several guide wheels disposed inside the shear housing. The guide wheels are rotatably connected to the rear shell of the shear housing through their axles. The guide wheels cooperate with the rolling guide track to press and guide the rubber strip on the rolling guide track.

[0017] The second objective of this invention is to provide a control system for a medical tape cutting and fixing device with programmable length control, characterized in that it includes a control motherboard, a switch, a mode selection button, and a battery pack disposed on the cutting housing. The battery pack is electrically connected to the control motherboard, the switch, and the mode selection button. The control motherboard includes motor drive circuits respectively connected to a first motor and a second motor.

[0018] The advantages and positive effects of this utility model are:

[0019] 1. In this utility model, medical tape is placed on a tape fixing structure, and one end of the tape strip is placed on a rolling guide structure. As the tape strip is output towards the tape outlet, it passes through a cutting structure at the end of a shear shell. Once a set length is reached, the cutting structure cuts the tape strip, and then reverts to its original position. During this process, a pressing structure outside the shear shell applies pressure to the tape strip, ensuring its adhesive effect. The tape strip's output, pressing, and cutting are completed in one integrated process, and the cut surface is smooth and even, facilitating adhesion and improving work efficiency and quality.

[0020] 2. This utility model is powered by a lithium battery, eliminating the need for manual labor and reducing the physical exertion of staff. This device can reduce contamination caused by hand touching the tape, accurately control the length of the tape output, and adopts an integrated electric design, reducing the physical exertion of medical staff and improving work efficiency and quality.

Additionally, for the sake of simplifying the drawings, the same or similar technical features may be indicated only in one place in the same drawing.

[0035] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "setting," "connection," "fixing," and "screw-on" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Unless otherwise explicitly limited, those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances. The utility model will now be described in detail with reference to the accompanying drawings. Example 1

[0036] A programmable length controllable medical tape cutting and fixing device includes a cutting shell in which a medical tape 1 is placed. The cutting shell is provided with a tape fixing structure for placing the medical tape 1, a tape outlet 2 for outputting the tape strip of the medical tape 1, and a rolling guide structure disposed between the two for guiding the tape strip of the medical tape 1 from the medical tape 1 side to the tape outlet 2 side. The tape outlet 2 is provided with a cutting structure for cutting the tape strip of the medical tape 1 and a pressing structure for pressing the tape strip of the medical tape.

[0037] In this embodiment, medical tape is placed on a tape fixing structure, and one end of the tape strip is placed on a rolling guide structure. As the tape strip is pushed outwards, it passes through a cutting structure at the end of the shear shell. Once it reaches a set length, the cutting structure cuts the tape strip, and then the cutting structure returns to its original position. During this process, pressure is also applied to the tape strip through a clamping structure outside the shear shell to ensure effective adhesion. The tape strip's output, clamping, and cutting are all integrated, improving work efficiency and quality. This device effectively reduces contamination caused by hand contact with the tape. The cut surface of the tape strip is smooth and flat, facilitating adhesion, and the clamping structure ensures effective adhesion, further improving work efficiency and quality.

[0038] Furthermore, in this embodiment, the sheared outer shell may include a front cover 3 and a rear shell 4 assembled together, which may be separate or assembled together.

[0039] Furthermore, in this embodiment, the shearing housing is divided into a tape fixing area 5, a tape guiding area 6, a tape outlet 2 area, and a handle area 7. The tape guiding area 6 is located between the tape fixing area 5 and the tape outlet 2 area and is connected to each other.

[0040] Furthermore, in this embodiment, one could also consider, such as Figure 1-11 As shown, the tape fixing area 5 is cylindrical, and the tape fixing structure includes a tape fixing wheel 8 disposed within the tape fixing area 5. The tape fixing wheel 8 is rotatably connected to the rear shell of the shearing shell through its axle. The front side of the tape fixing wheel 8 is provided with a claw 9 for clamping the medical tape 1. The medical tape roll can be mounted on the tape fixing wheel through the claw and rotates with the rotation of the tape fixing wheel.

[0041] Furthermore, in this embodiment, the number of claws is not less than two, arranged in a circular array on the tape fixing wheel with the wheel axle as the center. The claws have a certain elasticity to hold the medical tape roll. The claws can be integrally set on the tape fixing wheel or slidably set on the tape fixing wheel. When slidably set, not less than two grooves can be radially opened on the front side of the tape fixing wheel with the wheel axle as the center. The claws are slidably connected to the grooves. A compression spring is also provided between the claws and the grooves to accommodate the installation of medical tape rolls of different specifications and sizes, thereby improving the practicality of the device.

[0042] Furthermore, in this embodiment, the clamping structure includes a clamping roller 22 disposed outside the tape outlet, which can clamp the tape onto the medical supplies to ensure adhesion. The clamping roller 22 is mounted on the outside of the shear housing via clamping brackets 23. Specifically, the clamping roller 22 is fixed to the shear housing outside the tape outlet 2 via two clamping brackets 23. The clamping brackets 23 are fixed to the shear housing via threads. The clamping brackets 23 contain replaceable springs, and the downward pressure of the clamping roller can be adjusted by replacing the springs.

[0043] Furthermore, in this embodiment, the clamping bracket 23 may be arranged horizontally.

[0044] Furthermore, in this embodiment, one could also consider, such as Figure 1-11As shown, the tape guiding area 6 is cubic in shape. The rolling guiding structure includes a rolling guiding track 10 disposed within the tape guiding area 6, a power roller 11 for driving the rolling guiding track 10 to roll, and a driven roller 12. The power roller 11 is driven by a first motor 13. The roller shaft of the power roller and the motor shaft of the first motor can be directly connected by a coupling or by gear transmission.

[0045] Furthermore, in this embodiment, the rolling guide track 10 extends along the length of the belt guiding area 6. One end of the rolling guide track 10 is close to the belt fixing wheel 8, and the other end is close to the cutting structure. The rolling guide track 10 is a rubber track, and its surface is provided with irregular stripes in the same direction of travel. The guide track is made of rubber, which is less prone to residual adhesive, and the irregular stripes in the same direction of travel reduce the impact on the adhesive force of the belt.

[0046] Furthermore, in this embodiment, the cutting structure can be a rotating blade structure or a scissor-type structure.

[0047] Furthermore, in this embodiment, when the cutting structure is a rotating blade structure, such as... Figure 9 As shown, the cutting structure includes a wedge-shaped blade 14 extending along the width direction of the tape guiding area and a cutting shaft. The wedge-shaped blade 14 is rotatably connected to the rear shell of the shearing housing via the cutting shaft. The cutting shaft is driven by a second motor 15. The cutting shaft and the motor shaft of the second motor can be directly connected via a coupling or via gear transmission. The second motor 15 can drive the wedge-shaped blade to rotate. When the wedge-shaped blade rotates so that its cutting edge faces the tape strip, it can cut the tape strip below it.

[0048] Furthermore, in this embodiment, a supporting cutting structure 17 can also be provided inside the shearing shell. The supporting cutting structure 17 is fixed on the rear shell of the shearing shell. The supporting cutting structure 17 is arranged opposite to the wedge blade 14. The upper end face of the supporting cutting structure can be set on the cutting edge of the wedge blade to play a supporting cutting role. When there is a gap between the cutting edge of the wedge blade and the supporting cutting structure, the tape strip can pass directly. When the cutting edge of the wedge blade rotates downward, it drives the tape strip to press against the cutting edge of the supporting cutting structure, so that the wedge blade can cut the tape strip.

[0049] Furthermore, in this embodiment, when the cutting structure is a scissor-type structure, the cutting structure includes scissor-shaped blades extending along the width direction of the tape guiding area and a control arm. The scissor-shaped blades are connected to the shearing housing via a connecting shaft, and the control arm is driven and controlled by a second motor to drive the scissor-shaped blades to cut the tape. When the scissor-type cutting structure is in the open state, the tape strip can pass directly through the gap between the upper and lower scissor-shaped blades. When the control arm is driven by the second motor, the upper and lower scissor-shaped blades close, cutting the tape strip.

[0050] It should be noted that the scissor structure is a known structure, and the specific structure and attached diagrams are not described in detail.

[0051] Furthermore, in this embodiment, it can also be considered that a number of guide wheels 16 are disposed inside the shear housing. The guide wheels 16 are rotatably connected to the rear shell of the shear housing through their axles. The guide wheels 16 cooperate with the rolling guide track 10 to press and guide the rubber strip on the rolling guide track 10.

[0052] The working principle of this embodiment is as follows: Figure 1-11 As shown, medical tape is placed on a tape fixing wheel via jaws, with one end of the tape strip resting on a rolling guide belt. The rolling guide belt is made of rubber, making it less prone to adhesive residue buildup, and features irregular stripes in the same direction of travel to minimize impact on the tape's adhesion. A first motor drives the rolling guide belt to rotate via a power roller, and the length of the tape strip output is controlled by the rotation time and speed of the first motor. Tape output is completed via a cutting structure at the end of the device. When the set length is reached, the first motor stops, and a second motor drives the cutting structure to cut the tape strip. After cutting, the second motor reverses, and the cutting structure returns to its original position. The tape is output through an opening at the end of the device. During output, pressure is applied to the tape using a pressure roller at the tail end. Tape output, pressure, and cutting are all integrated into one process, improving work efficiency and quality. For example, this device can preset three commonly used cutting lengths. Users select the corresponding length using buttons 1, 2, and 3. After pressing the start switch, the main control chip controls the first and second motors to operate, completing the tape output and cutting. Furthermore, a long press of the start switch allows for continuous tape output, stopping and cutting upon release, to accommodate temporary tape length requirements. The software also allows for flexible setting of the three preset lengths to meet different needs. Powered by a lithium battery, this device requires no manual operation, reducing the physical exertion of staff. It minimizes contamination caused by hand contact with the tape, precisely controls the tape output length, produces a smooth and even cut surface for easy application, and features a clamping structure to ensure effective adhesion. The integrated electric design further reduces the physical exertion of medical personnel, improving work efficiency and quality. Example 2

[0053] A control system for a programmable length controllable medical tape cutting and fixing device includes a control motherboard 18, a switch 19, a mode selection button 20, and a battery pack 21 disposed on the cutting housing. The battery pack 21 is electrically connected to the control motherboard 18, the switch 19, and the mode selection button 20. The control motherboard 18 includes motor drive circuits that are respectively connected to a first motor 13 and a second motor 15.

[0054] In this embodiment, a programmable controller chip (PCC) can be used as the control motherboard. The PCC stores programs to control the motors, thereby controlling the tape cutting length. Furthermore, three commonly used cutting lengths can be preset, and three mode selection buttons can be used to select the corresponding length. After pressing the start switch, the main control chip controls the first and second motors to work, completing the tape output and cutting. Taking this embodiment as an example, an Arduino Uno motherboard and the Mind+ programming software are used, powered by two 18650 lithium batteries and two micro stepper motors. The motherboard controls the rotation time of the first motor driving the power roller, thereby controlling the tape output length. Once the set length is reached, the second motor drives the cutting structure to cut the tape, and the guide wheel at the tail compresses the tape.
