Technical Field

[0001] This utility model belongs to the field of medical supplies technology and relates to a vascular compression hemostasis device. Background Technology

[0002] In clinical practice, after invasive vascular procedures such as intravenous infusion, blood transfusion, and arterial and venous blood sampling, it is necessary to apply pressure to the blood vessel for 1-5 minutes to stop bleeding. Currently, manual pressure or bandaging is commonly used for hemostasis. However, manual pressure can easily lead to wound bleeding or subcutaneous bruising if not performed properly. Bandaging, using a tourniquet or bandage, is cumbersome and inefficient. Furthermore, due to differences in doctors' operating habits and patients' wrist sizes, it is difficult to control the pressure applied to the blood vessel after bandaging, thus affecting the hemostatic effect and patient comfort. Utility Model Content

Detailed Implementation

[0026] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, which constitute a part of the present invention and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not intended to limit the scope of the present invention.

[0027] Example 1

[0028] This embodiment provides a vascular compression hemostasis device, such as... Figure 1 and Figure 2 As shown, the device includes a hemostatic patch 1 and a compression band 2. The compression band 2 includes an elastic segment 21, a scale 22, a fastener 23, and a band body 24. One end of the elastic segment 21 includes a first fixed end 211. The scale 22 includes a second fixed end 221 and a marking part 222. The first fixed end 211 and the second fixed end 221 are fixedly connected. The scale 22 is arranged along the elastic stretching direction of the elastic segment 21. The distance between the second fixed end 221 and the marking part 222 is greater than the length of the elastic segment 21. The marking part 222 is used to mark the position to which the other end of the elastic segment 21 needs to be stretched. The fastener 23 is located at the end of the band body 24 and can fix the stretched length of the elastic segment 21, so that the compression band 2 can compress and stop bleeding in blood vessels through the hemostatic patch 1.

[0029] The vascular compression hemostasis device of this embodiment, by arranging a scale 22 in the elastic stretching direction of the elastic segment 21, can mark the position to which the other end of the elastic segment 21 needs to be stretched, so that the operator can easily confirm that the elastic deformation of the elastic segment 21 has reached or exceeded the preset deformation amount, thereby ensuring that after the fastener 23 is fixed, the elastic segment 21 is stretched and maintained at the required length, so as to ensure that the tension on the compression band 2 exceeds the set threshold, thereby so that the blood vessel under the hemostatic patch 1 is subjected to appropriate compression force, ensuring a good hemostasis effect.

[0030] A preferred embodiment of this solution is as follows: Figure 2As shown, the ruler 22 is made of opaque material, and the marking portion 222 is the edge of the ruler 22. Optionally, the ruler 22 can be a sheet overlapping the elastic segment 21, or it can be an annular piece fitted around the outer periphery of the elastic segment 21. Preferably, the ruler 22 is located on the other side of the elastic segment 21 that contacts the skin. Before use, the ruler 22 covers the elastic segment 21. Since the first fixed end 211 and the second fixed end 221 are fixedly connected and the distance between the second fixed end 221 and the marking portion 222 is greater than the length of the elastic segment 21, the other end of the elastic segment 21 is located between the second fixed end 221 and the marking portion 222. As the elastic segment 21 is stretched, the other end of the elastic segment 21 gradually approaches the position of the marking portion 222. When the other end of the elastic segment 21 exceeds the marking portion 222 and protrudes from the ruler 22, it indicates that the deformation of the elastic segment 21 has reached the set deformation amount, and the tension on the compression band 2 exceeds the set threshold.

[0031] In order to allow the tension of the elastic segment 21 to more directly compress the blood vessel, such as Figure 2 As shown, the first fixing end 211 and the second fixing end 221 are both fixed on one side of the hemostatic patch 1, so that the elastic segment 21 is close to the hemostatic patch 1, and the tension generated by the elastic segment 21 after stretching can more directly apply the compressive force to the blood vessel.

[0032] Fastener 23 can be a buckle, cable tie, strap, adhesive strip, or other fastening component that can stretch the compression band 2 and fix it to the skin.

[0033] A preferred embodiment of this solution is as follows: Figure 2 and Figure 3 As shown, the fastener 23 is a Velcro fastener, including Velcro A piece 231 and Velcro B piece 232 located at both ends of the compression band 2, so that the compression band 2 can be fixed around the limb at the blood vessel.

[0034] Preferably, the Velcro A piece 231 is fixed to the back of the bandage 1, so that the compression band 2 is located on one side of the bandage 1. Compared with the bandage 2 being located on both sides of the bandage 1, the compression band 2 being located on one side of the bandage 1 can greatly facilitate the user's operation and can also increase the thickness of the material in the compression hemostatic area by increasing the thickness of the Velcro roughened area, thereby providing further protection for the hemostatic area.

[0035] Considering the different limb thicknesses of patients, in order to keep the occlusal area between the Velcro pieces after the compression band 2 wraps around the patient's limb constant and to ensure the fastening effect of the compression band 2, the length of Velcro piece B 232 is greater than the length of Velcro piece A 231. This ensures that Velcro piece B 232 always has enough length to cover the entire area of ​​Velcro piece A 231, so that the length of the occlusal area between the two remains the same as the length of Velcro piece A 231.

[0036] Taking radial artery hemostasis as an example, when using this device, align the center of the hemostatic dressing layer 12 with the bleeding point, apply the hemostatic patch 1 to the wrist, and use the transparent film layer 11 on the adhesive area around the hemostatic dressing layer 12 to adhere the hemostatic patch 1 to the skin. Pull the compression band 2 to extend the elastic segment 21. Since the ruler 22 has a marking part 222 at the other end along the elastic stretching direction of the elastic segment 21, when the other end of the elastic segment 21 exceeds the marking part 222 and protrudes from the ruler 22, it indicates that the deformation of the elastic segment 21 has reached the set deformation amount, and the tension on the compression band 2 exceeds the set threshold. At this time, while maintaining the extension of the elastic segment 21, wrap the compression band 2 around the wrist, and then attach and fix the hook and loop fastener B piece 232 and hook and loop fastener A piece 231 to complete the compression hemostasis of the radial artery.

[0037] Furthermore, such as Figure 3 As shown, the hemostatic patch 1 also includes a bleeding staining indicator area 13, which is located on the outer periphery of the hemostatic dressing layer 12. When blood comes into contact with a certain part of this area, the bleeding staining indicator area 13 will quickly turn red. This allows for a direct, convenient, and sensitive detection of whether there is blood leakage in the pressure area, and also prevents the blood from being covered by the watch strap when it leaks to the bottom of the bilateral watch strap areas.

[0038] Example 2

[0039] like Figure 4 As shown, the difference between the vascular compression hemostasis device in this embodiment and that in embodiment 1 is that the scale 22 is made of transparent material, and the marking part 222 includes multiple marking parts 222, which are distributed along the elastic stretching direction of the elastic segment 21.

[0040] The vascular compression hemostasis device of this embodiment can set different levels of tension thresholds for the elastic segment 21 by setting multiple marking parts 222 on the transparent ruler 22, so as to use it for compression hemostasis of blood vessels in different conditions, thereby improving the flexibility and safety of the vascular compression hemostasis device.

[0041] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present utility model should be included within the protection scope of the present utility model.
