Abstract
Description
Technical Field
[0001] This utility model relates to the field of hemostasis technology, and in particular to a hemostatic dressing. Background Technology
[0002] A hemostatic dressing is a medical product primarily used to stop bleeding from external injuries. Hemostatic dressings typically contain hemostatic agents or medicinal ingredients, which help to stop bleeding and promote wound healing when applied. A hemostatic dressing generally consists of a pad, a release film, and adhesive tape. This structure allows the hemostatic dressing to fit tightly to the wound while providing necessary protection and support.
[0003] Blood testing is an important part of clinical medical work, and blood collection is a necessary step before blood testing. Successful blood collection and avoiding wound contamination are crucial. Existing hemostatic dressings expose the cotton balls after opening the package, allowing them to come into contact with bacteria in the air and become contaminated, thus increasing the risk of infection at the blood collection site. When the cotton balls inside the hemostatic dressing absorb too much blood, they need to be replaced to maintain their absorbency. The traditional method is to completely tear the hemostatic dressing off the patient's skin, which can damage the patient's pores. During the replacement of the hemostatic dressing, the needle holes are exposed to the air, which can easily lead to infection and also affects the efficiency of dressing replacement.

[0030] Example 1
[0031] Reference Figures 1 to 4 As shown, this is the first embodiment of the present invention, providing a hemostatic dressing. This device includes a fixing element 100, a bandage 101, and a connecting assembly 102 disposed on the bandage 101. Adjusting the connecting assembly 102 enables quick replacement of the protective element 200; and...
[0032] The protective element 200 includes an adhesive tape 201 disposed on the bandage 101, a breathable component 202 disposed above the adhesive tape 201, and a pressing component 203 disposed below the adhesive tape 201. Adjusting the 202 prevents the needle hole from being contaminated, and adjusting the pressing component 203 prevents the needle hole from bleeding or bruising due to manual pressing by personnel.
[0033] During use, the person first adjusts the fixing element 100 to fix the bandage 101 to the skin around the needle hole with an adhesive substance. Then, the person adjusts the protective element 200 to apply appropriate pressure and prevent contamination of the needle hole, thus avoiding bleeding and bruising, and also preventing contamination caused by contact between the needle hole and bacteria in the environment.
[0034] Example 2
[0035] Reference Figures 1 to 5 As shown, this is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that the connecting component 102 includes an isolation patch 102a connected to the bottom of the bandage 101 and a circular groove 102b opened in the middle of the bandage 101. An adhesive substance is provided on the lower surface of the bandage 101. The adhesive substance provided on the bandage 101 is bonded and fixed to the skin, which helps the protective element 200 to be effectively aligned with the needle hole.
[0036] Furthermore, the breathable component 202 includes a gauze sheet 202a connected above the adhesive tape 201, an isolation patch 202b connected to the outer surface of the gauze sheet 202a, and an adhesive tape 202b-1 connected to the isolation patch 202b. The adhesive tape 202b-1 is bonded to the bandage 101. The adhesive tape 201 is connected to the circular groove 102b, and the size of the circular groove 102b is adapted to the size of the adhesive tape 201. The size of the isolation patch 202b is adapted to the outer surface size of the gauze sheet 202a. This effectively prevents the breathable component 202 from causing contamination from pinholes.
[0037] Furthermore, the pressing component 203 includes a gauze sheet 203a connected below the adhesive tape 201, and a cotton ball 203b connected to the inside of the gauze sheet 203a. The upper and lower ends of the cotton ball 203b abut against the inside of the gauze sheet 202a and the gauze sheet 203a, respectively. The inside of the gauze sheet 202a and the gauze sheet 203a are provided with small ventilation holes. The cotton ball 203b, the gauze sheet 202a, and the gauze sheet 203a are all made of sterile material. Through the automatic adjustment of the pressing component 203, the needle hole can be effectively pressed appropriately.
[0038] During use, the person first removes the isolation patch 102a, then presses the bandage 101 flat onto the skin, aligning the circular groove 102b with the needle hole. Finally, the bandage 101 is secured to the skin near the needle hole using the adhesive material underneath, causing the bottom of the gauze pad 203a to contact the needle hole. Simultaneously, the gauze pad 203a contacts the cotton ball 203b, causing the cotton ball 203b to shrink into an oval shape, and its upper and lower ends to... The inner sides of gauze pad 202a and gauze pad 203a are connected with a natural slope. At the same time, gauze pad 202a is pressed downward by adhesive tape 201 under the fixation of bandage 101, so that cotton ball 203b is always pressed against the needle hole through gauze pad 203a. Through the adhesive method of isolation patch 202b and bandage 101, isolation patch 202b causes gauze pad 202a to always resist cotton ball 203b, thereby fixing cotton ball 203b.
[0039] After the bandage 101 is attached to the skin near the needle hole, the patient removes the isolation patch 202b, which is adhered to the gauze pad 202a. At this point, external air can enter the gauze pad 203a through the fine pores in the gauze pad 202a. When it is necessary to replace the cotton ball 203b, the isolation patch 202b is torn apart from the bandage 101, causing the gauze pad 202a to no longer press against the cotton ball 203b, exposing the cotton ball 203b to the outside. The cotton ball 203b is removed and replaced. After the cotton ball 203b is replaced, the adhesive tape 202b-1 is then attached to the bandage 101. The adhesive tape 202b-1, with its adhesive function, enables quick replacement of the hemostatic dressing. The gauze pad 203a isolates bacteria in the air, providing secondary local protection for the wound and preventing bacterial infection of the puncture site when the cotton ball 203b is replaced, thus improving the safety of the hemostatic dressing.
[0040] The remaining structure is the same as that in Example 1.
[0041] Example 3, as Figures 1 to 6 The image shows the third embodiment of the present invention. This embodiment provides a method for using a hemostatic dressing, including the following steps:
[0042] Step 1: Prepare a suitable hemostatic dressing, ensuring it is not expired and the packaging is intact. Then wash your hands and keep them clean to reduce the risk of infection.
[0043] Step 2: Gently rinse the puncture site and surrounding skin with saline solution or clean tap water to remove any blood or dirt that may be present.
[0044] Step 3: Gently peel off the isolation strip 102a at the bottom of the hemostatic dressing, while being careful to avoid touching the gauze pad 203a to prevent contamination.
[0045] Step 4: Align the patch with the needle hole, ensuring that the patch completely covers the needle hole and the surrounding area. Gently press the patch to make it adhere tightly to the skin, ensuring that the patch is flat and wrinkle-free.
[0046] Step 5: The patient then removes the isolation patch 202b and gauze pad 202a, and replaces the protective element 200 as needed.
[0047] Step Six: After applying the dressing, regularly observe the puncture sites. If there are signs of infection such as redness, swelling, or oozing, replace the dressing immediately and seek medical help.
[0048] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
