Description

Technical Field

[0001] The utility model relates to the technical field of medical tapes, in particular to a breathable medical tape. Background Art

[0002] As a basic medical product, medical tape is non-toxic, non-irritating, soft, and easy to unwind. It is often used in central sterilization supply rooms, operating rooms, and dental departments.

[0003] For example, a medical tape with good air permeability with publication number CN217417662U utilizes the setting of a pressing rod and two connecting grooves. The pressing rod moves in the two connecting grooves, so that after the required tape is pulled out, the pressing rod is pressed against the tape, and then the tape is pulled to make the tape tear off smoothly. At the same time, due to the limitation of the pressing rod, the tape will not be pulled out, avoiding affecting the subsequent use of the tape, thereby improving the convenience of using the tape; utilizing the setting of the rubber sleeve, the friction force of the limiting shaft in the limiting groove is increased by the rubber sleeve, so that the limiting shaft will not automatically move when not subjected to a large external force, thereby improving the stability of the use of the pressing rod;

[0004] When the above technical solution is in use, the tape is pressed against the rod so that the tape is torn off smoothly and then pasted on the patient's skin. However, when the tape is in contact with the patient's skin for a long time, the skin is prone to various allergic reactions such as redness and itching due to long-term airtightness, and causes discomfort at the application site. The breathability of the tape in the above technical solution is poor.

[0005] Therefore, we proposed that breathable medical tape can solve the above problems well. Utility Model Content

[0015] Preferably, the rack is arranged in a "T" shape, and the rack and the protective shell are slidably connected.

[0016] Compared with the prior art, the utility model has the following beneficial effects: the breathable medical tape adopts a new structural design, and its specific contents are as follows:

[0017] (1) The antibacterial layer can effectively inhibit the growth of bacteria. At the same time, the air holes and air permeable layer can effectively reduce the direct contact area between the adhesive layer and the skin, avoiding the accumulation of sweat and moisture around the wound, thereby improving the air permeability of the tape body and improving the comfort of the patient;

[0018] (2) Pull the drive plate upward, so that the drive plate drives the meshing active gear to rotate by the tooth block, and at the same time the active gear drives the meshing rack and the cutting blade to move downward and extend out of the protective shell. At this time, the cutting blade can be used to allow medical staff to quickly tear off the tape body, and the incision is relatively smooth, which is more time-saving and labor-saving than manual tearing;

[0019] Furthermore, when the medical staff releases the driving plate, the active gear rotates in the opposite direction under the stored force of the vortex spring, and drives the rack and the cutting blade to reset and be stored in the protective shell, thereby preventing the cutting blade from causing harm to the user when not in use;

[0020] (3) When the tape body is torn off, the distance between the tape body wound on the winding frame and the pressure plate will become larger. At this time, the elastic force of the return spring is used to drive the slider to move downward, and the connecting rod is used to drive the pressure plate to move downward, so that the pressure plate always presses the tape body tightly, thereby preventing the tape body from wrinkling and affecting its use.
