Description

Technical Field

[0001] The present invention relates to the field of cutters, and particularly to a medical tape dispenser. Background Art

[0002] A tape dispenser is an auxiliary tool for placing tapes and enabling quick cutting. It includes a base and a tape mounting ring that can be removed and replaced. A cutting knife is provided at the front end of the base. After placing the tape in the tape mounting ring, tearing and pulling out the tape, determining the length according to requirements, and then pressing down to make the tape contact the cutting knife to achieve the cutting effect. The remaining pulled-out part of the tape adheres above the cutting knife, facilitating the next pick-up. The tape dispenser replaces the way of cutting with a hand-held tool, which is safer and more convenient, and is widely used in scenarios where tapes are frequently used, which can greatly improve the cutting efficiency of tapes.

[0003] In the medical field, there are also some scenarios where a tape dispenser is needed. In medical use, the length of the tape is usually required to be relatively precise. If the tape is cut too short, it is likely to adhere insecurely, causing the needle to fall off. If it is too long, it will affect the patient's comfort and is also wasteful. Currently, most tape cutting is done by feeling, and it is inconvenient to determine the length of the cut tape, resulting in either a failure to achieve the adhesion effect or discomfort to the patient. Summary of the Invention

[0004] In order to overcome the deficiencies of the prior art, one of the purposes of the present invention is to provide a medical tape dispenser to solve the problem that the length of the cut tape is inconvenient to determine in the prior art, resulting in either a failure to achieve the adhesion effect or discomfort to the patient.

[0005] To achieve the above purpose, the present invention provides a medical tape dispenser, including a tape dispenser main body. A measuring scale is provided on the side of the tape dispenser main body, and the measuring scale can slide out as the tape is pulled out.

[0006] Principle of the technical solution: The tape dispenser main body includes a base and a cutting knife. The tape is placed in the base. During use, the tape is pulled out and pressed down to contact the cutting knife to achieve the cutting action. The measuring scale slides out as the tape is pulled out, allowing the user to intuitively understand the length of the pulled-out tape, facilitating the cutting of an appropriate length, which can effectively adhere and avoid discomfort to the patient.

[0007] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. The measuring scale can measure the length of the pulled-out tape, facilitating the cutting of the tape with the required length.

[0008] 2. The measuring scale slides out as the tape is pulled out, enabling direct measurement of the tape length, eliminating the step of manually taking the measuring scale for measurement, and not adding new steps for cutting the tape, which is convenient and fast to use.

[0009] As a preferred embodiment of the present invention, a coupling structure and a rotating shaft are provided on one side of the tape holder body close to the measuring ruler, the coupling structure is clamped with the rotating shaft, and a mounting ring is fixed on the rotating shaft, and the mounting ring is used to clamp with the tape; the other end of the coupling structure is fixedly connected to a first gear, and one side of the first gear is engaged with a second gear; a horizontally slidable rack is provided in the tape holder body, the rack is engaged with the second gear, and the side surface of the rack passes through the tape holder body and is fixedly connected to the measuring ruler.

[0010] The principle and beneficial effects of the technical solution are as follows: the mounting ring clamps the tape so that the rotation of the tape drives the rotating shaft to rotate. The coupling structure is used to rotate with the rotating shaft, drive the first gear to rotate, and drive the rack to extend under the connection of the second gear. The rack slides out horizontally under the restriction of the tape holder body, driving the measuring ruler to slide out; the second gear is used to transmit and change the direction of rotation so that the sliding direction of the rack is consistent with the direction of tape pulling.

[0011] As a preferred embodiment of the present invention, the coupling structure includes a connecting ring, the outer side of the connecting ring is coaxially fixed with the first gear, the inner side is provided with a ratchet groove, a pawl is rotatably provided on the rotating shaft, and the inner side of the pawl is provided with a torsion spring, and the torsion spring is used to pop out the pawl outward; when the tape is pulled out, the pawl pops out and presses against the ratchet groove, so that the connecting ring and the rotating shaft rotate together; when the connecting ring is reversed, the pawl slides and is staggered with the ratchet groove, so that the rotating shaft remains stationary.

[0012] The principle and beneficial effects of the technical solution are as follows: when the tape is pulled out, the pawl pops out and presses against the ratchet groove, causing the connecting ring and the rotating shaft to rotate together, thereby driving the first gear and the second gear to rotate, causing the rack to slide out; and when the measuring ruler is pushed back when not in use, the rack is pushed back, the second gear, the first gear and the connecting ring are reversed, and the pawl slides and staggers with the ratchet groove, so that the rotating shaft remains stationary, thereby preventing the tape stuck on the cutting blade of the tape holder body from rotating and retracting, which is inconvenient for the next use.

[0013] As a preferred embodiment of the present invention, a sliding groove is provided in the tape holder body, and the connecting ring is provided with an opening, and the rotating shaft can pass through the opening and slide out upward along the sliding groove.

[0014] Principle and beneficial effects of the technical solution: The upward sliding of the rotating shaft can facilitate the replacement of the tape and achieve the effect of repeated use.

[0015] As a preferred embodiment of the present invention, a limiting plate is fixed on the rotating shaft, and the limiting plate is used to limit the maximum pop-up angle of the pawl.

[0016] Principle and beneficial effects of the technical solution: The limiting piece is used to limit the maximum ejection angle of the pawl, so that it always remains inside the connecting ring, avoiding being stuck at the opening.

[0017] As a preferred embodiment of the present invention, a torsion spring is fixedly connected to the side surface of the first gear, and the other end of the torsion spring is fixedly connected to the tape seat body for rewinding the first gear.

[0018] Principle and beneficial effects of the technical solution: When the tape is pulled out to drive the rotation of the first gear, the torsion spring undergoes elastic deformation. When the tape is cut and released, under the elastic force of the torsion spring, the first gear rotates in the reverse direction to pull back the measuring ruler for the next measurement.

[0019] As a preferred embodiment of the present invention, a dust cover is rotatably connected above the tape seat body, and the dust cover can cover the tape seat body.

[0020] Principle and beneficial effects of the technical solution: The dust cover shields above the tape seat body, reducing the entry of dust and bacteria, and playing a role in protecting the tape.

[0021] As a preferred embodiment of the present invention, a storage box is fixedly connected to the back side of the tape seat body.

[0022] Principle and beneficial effects of the technical solution: The storage box can be used to store some auxiliary tools, such as knives, etc., improving the practicality. BRIEF DESCRIPTION OF THE DRAWINGS

Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of the described features. In the description of the embodiments of the present invention, "a plurality" means two or more unless otherwise specifically defined.

[0034] The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0035] As shown in the attached Figures 1 to 3As shown in the figure, the present invention provides a medical tape dispenser, which includes a tape dispenser main body 1. The tape dispenser main body 1 includes a base and a cutting scissors. The tape is placed in the base. When in use, the tape is pulled out and contacts the cutting scissors downward to achieve the cutting action. After cutting, the pulled-out tape adheres to the cutting scissors. The tape dispenser main body 1 is provided with a sliding groove 9, and a rotating shaft 4 is arranged in the sliding groove 9. The rotating shaft 4 can slide out along the sliding groove 9 to facilitate tape replacement. An installation ring 5 is fixed on the rotating shaft 4, and the installation ring 5 is used for clamping the tape. By clamping the tape with the installation ring 5, the rotation of the tape drives the rotating shaft 4 to rotate.

[0036] As shown in the attached Figure 4 and Figure 5 figure, in this embodiment, a coupling structure 3 is arranged in the tape dispenser main body 1. The coupling structure 3 includes a connecting ring 31. A first gear 6 is arranged on the outer side of the connecting ring 31. The connecting ring 31 and the first gear 6 are coaxially fixed. A second gear 7 meshes with one side of the first gear 6. A horizontally slidable rack 8 is arranged in the tape dispenser main body 1. The rack 8 meshes with the second gear 7. The side surface of the rack 8 penetrates through the tape dispenser main body 1, and the part located outside the tape dispenser main body 1 is connected with a measuring scale 2. The connecting ring 31 drives the first gear 6 to rotate, and under the connection of the second gear 7, drives the rack 8 to extend out. The rack 8 slides out horizontally under the limitation of the tape dispenser main body 1, driving the measuring scale 2 to slide out. The second gear 7 is used for transmitting and changing the rotation direction, so that the sliding direction of the rack 8 is the same as the direction of the tape being pulled out.

[0037] As shown in the attached Figure 4 figure, in this embodiment, a ratchet groove 32 and an opening 35 are arranged on the inner side of the connecting ring 31. The opening 35 is used for the rotating shaft 4 to slide out. A pawl 33 is rotatably arranged on the rotating shaft 4. A torsion spring 34 is arranged on the inner side of the pawl 33. The torsion spring 34 is used for popping out the pawl 33 outward. A limiting piece 36 is fixed on the rotating shaft 4. The limiting piece 36 is used for limiting the maximum popping angle of the pawl 33, so that it always remains inside the connecting ring 31 and avoids getting stuck at the opening 35. When the tape is pulled out, the rotating shaft 4 rotates along with the tape, and the pawl 33 pops out and abuts against the ratchet groove 32, so that the connecting ring 31 and the rotating shaft 4 rotate together, thereby driving the first gear 6 and the second gear 7 to rotate, and making the rack 8 slide out.

[0038] As shown in the attached Figure 6As shown, in this embodiment, a coil spring 10 is fixedly connected to the side of the first gear 6, and the other end of the coil spring 10 is fixedly connected to the tape holder body 1. When the tape is pulled out and drives the first gear 6 to rotate, the coil spring 10 undergoes elastic deformation. When the tape is cut and loosened, under the elastic force of the coil spring 10, the first gear 6 is reversed, and the measuring ruler 2 is pulled back to facilitate the next measurement. At this time, the pawl 33 and the ratchet groove 32 slide and stagger, so that the rotating shaft 4 remains stationary, thereby preventing the tape stuck on the cutting knife of the tape holder body 1 from rotating and retracting, which is inconvenient for the next use.

[0039] As attached Figure 1 As shown, in this embodiment, a dust cover 11 is rotatably connected to the top of the tape holder body 1, and the dust cover 11 can cover the top of the tape holder body 1 to reduce the entry of dust and bacteria and protect the tape; a storage box 12 is fixedly connected to the back side of the tape holder body 1, and the storage box 12 can be used to store some auxiliary tools, such as knives, etc., to improve practicality. A spring wire can be provided in the storage box 12 to fix the pen and prevent the pen from scattering and falling.

[0040] As attached Figure 1 As shown, in this embodiment, a mounting frame 13 is fixed above the tape holder body 1, and a roller 14 is provided in the mounting frame 13. The lower end of the roller 14 and the upper surface of the cutting knife of the tape holder body 1 are at the same horizontal plane; the pulled tape is passed from under the roller 14, and the subsequently pulled tape can be parallel to the measuring ruler 2 under the restriction of the roller 14, so that the detected data is more accurate; at the same time, the roller also has a tensioning function, so that the pulled tape maintains a certain tension.
