Description

Technical Field

[0001] This utility model relates to the technical field of medical devices and related fields, and in particular to a portable hemostat for bleeding through vascular access. Background Technology

[0002] Hemodialysis is a process in which blood is drawn from a patient through a blood vessel and fed into a dialyzer, where substances are exchanged before being returned to the patient. Because the needle used for dialysis is relatively thick, hemostasis after dialysis is difficult and requires 15-20 minutes of pressure to stop the bleeding. In practice, dialysis bandages are commonly used for pressure hemostasis, but this method is cumbersome and cannot be reused. Utility Model Content

[0020] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, but this is not intended to limit the present invention.

[0021] like Figures 1 to 3 As shown, a preferred embodiment of a portable hemostat for vascular access bleeding is illustrated, comprising: a pressure-applying element 1 and a fixing strap 2.

[0022] The two ends of the fixing band 2 are respectively installed on the two ends of the pressure applying member 1; the surface of the pressure applying member 1 facing the fixing band 2 is provided with a positive pressure part 11 and a two-sided pressure part 12, and the two-sided pressure parts 12 are symmetrically arranged along the positive pressure part 11; a sterile adhesive layer 3 is provided on the positive pressure part 11 and the two-sided pressure parts 12.

[0023] In actual use, the positive pressure part 11 on the pressure application part 1 is placed directly against the bleeding point. At this time, the positive pressure part 11 presses the bleeding point, and the two lateral pressure parts 12 are located on both sides of the bleeding point, which can also press the bleeding point at an angle. Finally, the pressure application part 1 is fixed by the fixing strap 2.

[0024] Furthermore, in a preferred embodiment, the fixing strap 2 includes: an elastic band segment 21 and a Velcro segment 22; one end of the elastic band segment 21 and one end of the Velcro segment 22 are connected. Furthermore, the elastic band end 21 allows the device to be adapted to different people, and the Velcro segment 22 can be used to secure the device.

[0025] Furthermore, in a preferred embodiment, the pressure-applying member 1 has a through hole 13 at each end. The other end of the elastic band segment 21 is fixedly installed in one through hole 13, and the other end of the Velcro segment 22 passes through another through hole 13 and is attached to the Velcro segment 22. Further, one through hole 13 of the pressure-applying member 1 is used to fix one end of the fixing band 2, and the other through hole 13 of the pressure-applying member 1 is used for the other end of the fixing band 2 to pass through and achieve temporary fixation to itself.

[0026] Furthermore, in a preferred embodiment, the height of the forward pressing part 11 is higher than the height of the two side pressing parts 12.

[0027] Furthermore, as a preferred embodiment, the pressure-applying member 1 can be either planar or arc-shaped. Further, when the pressure-applying member 1 is planar, it is made of a latex material in an elastic sheet shape, allowing it to deform slightly according to usage conditions for greater comfort. When the pressure-applying member 1 is arc-shaped with a central outward convexity, it can be made of metal.

[0028] Furthermore, as a preferred embodiment, the positive compression portion 11 is cylindrical. Furthermore, the cylindrical positive compression portion 11 allows for better hemostasis of the bleeding site.

[0029] Furthermore, as a preferred embodiment, the lateral pressure portion 12 can be either a cylinder or a cuboid. Further, when the pressure-applying member 1 is planar, the lateral pressure portion 12, see... Figure 1 As shown, a cylinder is used. When the pressure-applying component 1 is arc-shaped, see [reference needed]. Figure 2 and Figure 3 The lateral compression member 12 is a cuboid, and to make it more comfortable to use, the lateral compression member 1 is tilted toward the bleeding point and has an arc-shaped surface.

[0030] Furthermore, in a preferred embodiment, the aseptic patch layer 3 is composed of, from the inside out, a first tearable protective film layer, an adhesive layer, a waterproof layer, a bleeding layer, a hemostatic layer, and a second tearable protective film layer. Further, the aseptic patch layer 3 can be attached only to the positive compression portion 11, or it can simultaneously cover the positive compression portion 11 and the two lateral compression portions 12. The aseptic patch layer 3 is a consumable and needs to be replaced after each use. It comprises, in sequence, a tearable protective film layer, an adhesive layer, a waterproof layer, a bleeding layer, a hemostatic layer, and a tearable protective film layer. Before use, after tearing off the first tearable protective film layer, the adhesive layer is used to fix it to the positive compression portion 11. After tearing off the second tearable protective film layer, the hemostatic layer covers the bleeding point, and then the fixing band 2 is fixed. The state of the fixing band 20 after wearing is as follows... Figure 2 As shown, the positive compression part 11 is located directly above the fistula 4 and is used to apply positive compression to the fistula 4. The two lateral compression parts 12 are pulled towards the bleeding point under the stretching of the fixation band 2, and apply oblique compression to both sides of the fistula 4.

[0031] The above description is only a preferred embodiment of the present utility model and does not limit the implementation method and protection scope of the present utility model. Those skilled in the art should realize that all solutions obtained by equivalent substitutions and obvious changes made based on the description and illustrations of the present utility model should be included within the protection scope of the present utility model.
