Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to a pressure-adjustable dressing structure. Background Technology

[0002] Currently, the care of puncture sites, hemostasis, and fixation of puncture instruments all rely on pressure-adhesive bandages or dressings for compression care and hemostasis, simultaneously secured with adhesive tape. For example, a pressable infusion hemostatic dressing disclosed in patent number CN211863110U includes a release layer, an adhesive layer, and a dressing body. The adhesive layer is positioned between the release layer and the dressing body. The release layer has a first ear and a third ear on each side, and a covering layer on top. The adhesive layer has a second ear and a fourth ear on each side, with the second ear corresponding to the first ear and the fourth ear corresponding to the third ear. The adhesive layer has an adhesive area and an anti-slip area, with a tourniquet within the adhesive area and a core on the tourniquet. The dressing body is integrally connected to the adhesive layer.

[0003] This type of fixation method, with its fixed covering pressure, can lead to excessive or insufficient pressure when facing different puncture sites and different pulse pressures, resulting in tissue necrosis or bleeding. Utility Model Content

[0025] The embodiments of the present utility model will now be described in detail with reference to the accompanying drawings. To make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the technical solutions of the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of the present utility model, but not all embodiments.

[0026] Therefore, the following detailed description of the embodiments of the present invention provided in conjunction with the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0027] Example 1

[0028] like Figures 1-4 As shown, the pressure-adjustable dressing structure provided in this embodiment is mainly composed of a connecting unit 10 with a through hole 11, an adhesive unit 20 disposed below the connecting unit 10, an adjustment unit 30 movably disposed on the through hole 11, an elastic compression unit 40 disposed on the connecting unit 10, and a hemostatic cotton body 50 disposed at the end of the elastic compression unit 40. In use, the adjustment unit 30 can be displaced along the center line of the connecting unit 10 under the action of external force. The elastic compression unit 40 moves with the adjustment unit 30 and thereby adjusts the pressure of the hemostatic cotton body 50 on the human wound. The hemostatic cotton body 50 is used to adhere to the human wound or puncture site.

[0029] The compression body 42 includes a base plate 421. One side of the base plate 421 is in contact with the hemostatic cotton body 50. The other side of the base plate 421 is provided with a main guide body 422 and a secondary guide body 423. The main guide body 422 is located at the center of the base plate 421, and the two secondary guide bodies 423 are respectively located at opposite corners of the base plate 421. The main guide body 422 and the secondary guide bodies 423 adopt a columnar structure.

[0030] Correspondingly, a guide tube 31 protrudes from the adjustment unit 30. There is a gap between the guide tube 31 and the inner wall of the adjustment unit 30. The gap allows one end of the elastic body 41 to be inserted. The other end of the elastic body 41 is sleeved on the main guide body 422 and abuts against the base plate 421. The guide tube 31 allows the main guide body 422 to pass through. The elastic body 41 can be a spring. Multiple slots 311 are provided on the side wall of the guide tube 31, which has a certain telescopic performance to facilitate the entry of the head of the main guide body 422. Here, the head of the main guide body 422 is larger than its rod.

[0031] Additionally, the connecting unit 10 is provided with a plurality of guide holes 12 at one end facing the hemostatic cotton body 50, and the guide holes 12 allow the secondary guide body 423 to pass through.

[0032] Thus, stable and accurate guiding linear motion is achieved through the cooperation between the guide tube 31 and the main guide body 422, and between the guide hole 12 and the secondary guide body 423.

[0033] A connecting plate 13 is provided horizontally outward below the connecting unit 10. The connecting plate 13 has an opening 131 that communicates with the through hole 11. The adhesive unit 20 is connected to the connecting plate 13 and is used to adhere to the human body. Adhesive tape can be used.

[0034] Meanwhile, in order to facilitate the linkage between the adjustment unit 30 and the connecting unit 10, the connecting unit 10 and the adjustment unit 30 adopt a threaded structure. For example, an internal thread is provided in the connecting unit 10, and a corresponding external thread is provided on the adjustment unit 30. At the same time, anti-slip texture 301 is provided on the outer wall of the adjustment unit 30 to facilitate the application of force.

[0035] In use, the entire unit is attached to the desired position by the adhesive unit 20, and the pressure of the hemostatic cotton body 50 to the human wound is adjusted by rotating the adjustment unit 30. Medical staff can freely choose to increase or decrease the pressure according to their experience and usage needs.
