DETAILED DESCRIPTION

[0020] The utility model is further described in detail below in conjunction with specific embodiments. It should be understood that the specific embodiments described herein are only used to explain the utility model and are not used to limit the utility model. In the description of the utility model, it should be understood that the terms "center", "longitudinal", "lateral", "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like indicate the orientation or position relationship based on the orientation or position relationship shown in the drawings, which is only for the convenience of describing the utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation of the utility model. In the description of the utility model, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected, or indirectly connected through an intermediate medium, or it can be a connection between the two components. For ordinary technicians in this field, the specific meanings of the above terms in the utility model can be understood by specific circumstances.

[0021] As shown in the figure, the utility model provides a tension-reducing zipper-type multifunctional bandage, comprising a first flexible patch 1, a second flexible patch 2, three tension strips 4 and tension rings 5 ​​corresponding to the tension strips, the tension strips 4 are arranged at intervals, one end of the tension strip 4 is connected to the first flexible patch 1, the tension ring 5 is connected to the second flexible patch 2, the other end of the tension strip 4 can be inserted into the tension ring 5, and the surface of the tension strip 4 has serrations (see Figure 3 ) structure 4-2; the serrated structure 4-2 can be tightly buckled with the tension ring 5 to ensure that there is no rebound and to ensure that the wound will not be contaminated by secondary contamination;

[0022] The tensioning strip 4 has a strip-shaped cavity, and the end of the strip-shaped cavity close to the first flexible patch 1 is a closed end. There is liquid medicine in the strip-shaped cavity, which is coated in a sealing film 4-6. The shape of the sealing film 4-6 coating the liquid medicine is adapted to the strip-shaped cavity. The sealing film 4-6 needs to ensure good sealing to ensure that there is no leakage. The bottom surface of the tensioning strip 4, close to the first flexible patch 1, has a liquid outlet 4-1 that passes through the strip-shaped cavity. The upper surface of the tensioning strip 4 has a long hole that extends along the tensioning strip 4 and passes through the strip-shaped cavity. A push rod 4-3 is passed through the long hole. The push rod 4-3 is slidably connected to the long hole. The lower end of the push rod 4-3 is deep into the strip-shaped cavity. The lower end of the push rod 4-3 has a push block 4-5, and the upper end extends out of the tensioning strip 4. The push block 4-5 abuts against the end of the sealing film 4-6 coating the liquid medicine close to the second flexible patch 2. In this embodiment, the liquid medicine coated by the sealing film 4-6 is iodine tincture. In addition to iodine tincture, other liquid medicines that are beneficial to healing wounds, such as physiological saline, etc., can also be selected.

[0023] In this structure, the push rod 4-3 can slide in the long hole to push the push block 4-5 to push the sealing film 4-6 toward the closed end of the strip cavity, and extrusion is formed between the end of the sealing film 4-6 and the closed end of the strip cavity. The sealing film 4-6 is ruptured after being squeezed, and the drug liquid can be retained outside the tension strip 4 at the liquid outlet 4-1 so as to administer the drug to the wound surface.

[0024] When the tension strip 4 passes through the tension ring 5, the push rod 4-3 contacts the tension ring 5. The tension ring 5 pushes the push rod 4-3 to slide in the long hole, so that the tension strip 4 and the tension ring 5 are locked and drive the push block 4-5 to push the sealing film 4-6 to apply medicine to the wound surface.

[0025] The first flexible patch 1 and / or the second flexible patch 2 are connected with an absorbent cotton sheet 3, and the absorbent cotton sheet 3 may contain Yunnan Baiyao powder, which can accelerate the wound healing speed without ensuring that the wound is infected.

[0026] The first flexible patch 1 can be provided with an expandable medical waterproof breathable membrane (disinfected), a positioning chip or a one-button alarm 6. The expandable medical waterproof breathable membrane is compressed into a smaller block and then adhered to the flexible patch. After being expanded, it can cover the surface of the band-aid to prevent bacterial contamination, etc. The alarm can be used to contact the outside world and save oneself when the injured person is unable to move or cannot use communication equipment, and the positioning chip can be accurately found after the user reports the alarm, thereby shortening the search time and enabling the injured person to receive effective treatment as quickly as possible.

[0027] The surface where the tension strip 4 contacts the first flexible patch 1 is a plane, and the plane design can increase the contact area between the two, which is beneficial for fixation.

[0028] like Figure 5As shown, there is a cutting blade 4-4 in the liquid outlet 4-1, and the sharp surface of the cutting blade 4-4 is facing the end of the sealing film 4-6 near the liquid outlet 4-1. The setting of the cutting blade 4-4 can quickly cut the sealing film 4-6 located at the liquid outlet 4-1, so that the liquid medicine can flow out quickly. The design of the cutting blade 4-4 can only cut the sealing film 4-6, and there must be safety protection measures at a distance from the skin to prevent the skin from being hurt. Due to the setting of the cutting blade 4-4, it is necessary to take limiting measures to prevent the sealing film 4-6 from freely moving in the tension strip 4, so it is necessary to set a limiting tape 4-7 on the tension strip 4, limit the push rod 4-3 between the limiting tape 4-7 and the end of the long hole, and the end of the sealing film 4-6 needs to be bonded to the push block 4-5, so that before use, it can effectively avoid leakage caused by the contact between the sealing film 4-6 and the cutting blade 4-4 due to movement. After tearing off the limiting tape 4-7 before formal use, it can be used normally.

[0029] The above is a detailed description of the embodiments of the utility model, but the contents are only preferred embodiments of the utility model and cannot be considered to limit the scope of implementation of the utility model. All equivalent changes and improvements made within the scope of application of the utility model should still fall within the scope of the patent coverage of the utility model.
