Problems solved by technology

[0004] The above-mentioned solution solves the problem that the traditional bandage is easy to adhere to the wound and cause secondary blood in the prior art to a certain extent, but there are still many deficiencies in this solution. Or pressure relief, the accuracy of hemostasis is not high, and the use effect is not good

Embodiment 1

[0026] like Figure 1-5 As shown, the positive pressure zone transparent and adjustable limb wound hemostatic device includes a flexible sheet-like hemostatic body 1 made of transparent materials, and the sheet-like hemostatic body 1 has a number of sequentially distributed and independent of each other. Inflatable cavity 11, between the two opposite sides of the sheet-shaped hemostatic body 1 is provided with a hemostatic sheath 12 that can form the sheet-shaped hemostatic body 1 into a cylindrical shape, so that each inflatable cavity 11 is surrounded by a detachable ring-shaped structure. The connecting structure 13, the inflatable cavity 11 are respectively distributed along the axial direction of the hemostatic sheath 12 and the two ends of the hemostatic sheath 12 are respectively opened, and the inflatable cavity 11 is respectively connected with the expansion and contraction control mechanism 2, and the inside of the sheet-shaped hemostatic body 1 And the inner side of...

Embodiment 2

[0037] like Image 6 As shown, the structure and principle in this embodiment are the same as those in Embodiment 1, except that the surface layer 16 is located on the outside of the hemostatic sheath 12 in the circumferential direction, and the bottom layer 17 is located on the inner side of the hemostatic sheath 12 and is far away from the surface layer. One side of 16 has a smooth structure, and the thickness of the surface layer 16 is greater than that of the bottom layer 17 . When the sheet-shaped hemostatic body 1 is arranged in this way, the detachable structure is any one or a combination of a female button, a magnetic button, a press button and a hook arranged on both sides of the flexible connecting plate 15 .

[0038] To sum up, the principle of this embodiment is that the sheet-like hemostatic body 1 is surrounded by the detachable connection structure 13 to form a hemostatic sleeve 12, which is placed on the peripheral side of the wound surface of the patient's li...

Abstract

The invention relates to a positive pressure partition transparent adjustable limb wound hemostasis device. The problem that in the prior art, partitioned pressurization hemostasis cannot be achieved is solved. The haemostat comprises a flexible flaky haemostat which is made of a transparent material and provided with a plurality of inflation cavities which are sequentially distributed and mutually independent. A detachable connecting structure is arranged between the two oppositely arranged side edges of the sheet-shaped hemostasis body, the sheet-shaped hemostasis body can form a cylindrical hemostasis sleeve body, so that the inflation cavities are defined to form an annular structure, the inflation cavities are sequentially distributed in the axial direction of the hemostasis sleeve body, and the two ends of the hemostasis sleeve body are each provided with an opening; the inflation cavities are connected with expansion and contraction control mechanisms respectively, and the portion, located on the circumferential inner side of the hemostasis sleeve body, of the inner side of the sheet-shaped hemostasis body is of a smooth structure. The hemostat has the advantages that bleeding spots can be observed at any time for segmented pressurization hemostasis, and the use effect is good.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a device for hemostasis on extremity wounds with transparent and adjustable positive pressure zones. Background technique [0002] How to reduce the amount of bleeding in large-area burn wounds and escharectomy has always been a problem that scholars at home and abroad have been trying to solve. At present, there are many clinically applied methods, such as wound injection of swelling fluid, application of hemostatic gauze on the wound, and hemostatic drugs. It is still not ideal. The current application of hemostatic materials has significantly increased the cost of the patient. The use of blood in the treatment of large area burns has caused clinical concerns. Especially when it is difficult to use blood, the treatment of many critically ill patients is difficult to implement smoothly. Among them, traditional saline Gauze pressurizes the hemostasis, because the gauze ...
