Technical Field

[0001] The utility model relates to the technical field of infusion auxiliary equipment, in particular to a skin bandage device. Background Art

[0002] The preferred site for intravenous puncture is the forearm. After tying the cuff at the elbow, a suitable venous puncture site should be located in the forearm. Currently, this procedure often involves pulling the skin down and tightening it with one hand to prevent the vein from migrating. With the other hand, the needle is then positioned accurately in the vein before insertion.

[0003] Current forearm venipuncture procedures, where one hand bandages the skin while the other feels the pulse and inserts the needle, are inefficient, particularly for those with limited puncture experience, significantly impacting puncture success rates. The inventors sought to design an auxiliary device for this situation, eliminating the need for constant and strenuous bandage work. This frees both hands to accurately feel the pulse and improve puncture efficiency. Utility Model Content

[0023] The following describes in detail embodiments of the present invention, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present invention, and should not be construed as limiting the present invention. Example

[0024] See also Figures 1 to 4 As shown, the utility model provides a skin bandage device, which is suitable for being fixed on the patient's forearm 1 to assist in completing the puncture operation, including an arm grasping clamp 2, a tape fixer and a skin bandage tape 3; the arm grasping clamp 2 includes a first clamping body 2a and a second clamping body 2b rotatably connected by a pin shaft 4, and a torsion spring 2c passing through the middle of the pin shaft 4, and the two ends of the torsion spring 2c respectively elastically abut the inner side of the rotating end of the first clamping body 2a and the inner side of the rotating end of the second clamping body 2b; there are two tape fixers, and the two tape fixers are respectively installed on the outer side of the clamping end of the first clamping body 2a and the outer side of the clamping end of the second clamping body 2b; there are two skin bandage tapes 3, and one end of the two skin bandage tapes 3 is fixed on the tape fixer in a one-to-one manner.

[0025] In this application, by combining the forearm vein puncture scenario, a skin bandage device for auxiliary puncture is designed in a targeted manner. Before puncture, the arm clamp is opened by pressing the rotating end of the first clamp 2a and the rotating end of the second clamp 2b, and the clamping end of the first clamp 2a and the second clamp 2b are clamped on both sides of the upper part of the patient's forearm 1, and then the two skin bandage tapes 3 are pulled open in turn. When the forearm skin is tightened, the skin bandage tape 3 is operated to tilt around the forearm 1 to complete the gluing and fixing. Finally, the two skin bandage tapes can be operated to form an "X" shape to bandage the skin, and there is no need to use one hand to maintain the skin bandage operation. The convenient operation can improve the puncture efficiency.

[0026] According to one example of the present invention, the tape holder is a reel-out box 5 that is detachably mounted on the first clamp 2a or the second clamp 2b. The reel-out box 5 includes a box body 5a with an opening at one end and a box cover 5b that is detachably mounted on the box body 5a. The side of the box body 5a has a reel-out opening 5c. The bandage tape 3 is a rolled tape placed in the reel-out box 5. The box body 5a is also provided with a clip 6 next to the reel-out opening 5c ​​for elastically clamping the rolled tape. The tape holder designed in the form of a reel-out box 5 can store rolled tape, which is better for tape storage and continuous use. When in use, a section of tape is pulled out from the reel-out opening 5c ​​according to the estimated length of the patient's forearm. After being pulled out, the free end of the tape is tightened against the patient's forearm skin and then fixed. The portion of the tape located at the reel-out opening 5c ​​is clamped and tightened by the clip 6, making it difficult for the tape to loosen without external interference.

[0027] According to one example of the present invention, a clip slot 5d communicating with the unwinding port 5c is provided on the box body 5a on one side of the unwinding port 5c. In one design, the clip 6 is an elastic clip, one end of which is removably mounted in the clip slot 5d via a fastener, while the other end of the clip 6 passes through the unwinding port 5c and abuts against the other side of the unwinding port 5c. Alternatively, as another design, the clip 6 is a rigid clip, one end of which is fixed in the clip slot 5d via a spring connection, while the other end of the clip 6 passes through the unwinding port 5c and abuts against the other side of the unwinding port 5c. Preferably, the free end of the clip 6 is provided with equally spaced teeth 7 to enhance the clamping force on the tape at the unwinding port, preventing the tape from loosening.

[0028] As another feasible design, the tape holder can also be a plastic clip that can be removably mounted on the first clamping body 2a or the second clamping body 2b and can be opened and closed elastically. This design is more concise. The skin-binding tape 3 is a long strip of tape with one end clamped on the plastic clip. When using it, it is necessary to pull and cut the tape into two strips in advance, then clamp one end of the tape directly on the plastic clip, and finally cross the two strips in an X shape to tighten the skin and fix it.

[0029] Preferably, the bandage tape 3 can be medical sealing tape, which is made of pure wood pulp, a natural material, non-toxic and non-irritating, and has good air permeability. It is also soft and easy to unwind when pulled, making it very convenient to operate.

[0030] According to one embodiment of the present invention, the arm gripper 2 is a plastic gripper, and multiple spherical crown-shaped protrusions are evenly distributed on the inner side surfaces of the clamping ends of the first and second clamping bodies 2a. The spherical crown-shaped protrusions increase the contact friction between the inner side of the clamp and the patient's arm skin, providing a more stable grip.

[0031] Preferably, in this embodiment, an annular hole 8 is provided in the middle of the first clamp body 2a and the second clamp body 2b. This design can greatly reduce the weight of the clamp body and reduce the load on the forearm while ensuring the structural strength during use.
