Description

Technical Field

[0001] The utility model relates to the field of medical devices, and particularly relates to a dressing with a local compression effect. Background Art

[0002] In clinical practice, there are many open wounds that need to be compressed to stop bleeding. The sizes and shapes of the patients' wounds are different. Currently, sandbags are mostly used for compression, which cannot be adapted to the size and shape of the wound. For example, if the wound is too large, the compression is not in place, resulting in poor compression hemostasis effect; if the compression range on the wound is too large, thrombosis, pressure sores, etc. are likely to occur, which is not conducive to the healing of the patient's wound. Summary of the Utility Model

[0003] This part of the content of this application is used to briefly introduce the concepts, which will be described in detail in the following detailed implementation part. This part of the content of this application is not intended to identify the key features or essential features of the claimed technical solution, nor is it intended to limit the scope of the claimed technical solution.

[0004] To solve the technical problems mentioned in the above background art part, some embodiments of this application provide a dressing with a local compression effect, including a dressing body, a gauze, and a compression mechanism. The gauze and the dressing body enclose a cavity. The gauze is on the side close to the skin. The compression mechanism is placed in the cavity. The compression mechanism includes a compression airbag, a plurality of inflation chambers arranged equidistantly in an array on the compression airbag, and a plurality of inflation components respectively used to inject air into the plurality of inflation chambers. The inflation component includes an inflation tube fixedly arranged on the compression airbag and communicated with the inflation chamber, a one-way valve arranged inside the inflation tube, and a balloon fixedly arranged at the other end of the inflation tube. The balloon is communicated with the inflation tube.

[0005] Specifically, a plurality of protrusions are arranged on one side of the compression airbag.

[0006] Specifically, a plurality of arc surfaces are arranged on the other side of the compression airbag.

[0007] Specifically, two symmetric V-shaped grooves are arranged on the arc surface.

[0008] Specifically, adhesive layers are arranged at both ends of the dressing body, and a plurality of adaptation segments are arranged at equal intervals.

[0009] Specifically, the dressing body is also provided with four auxiliary adhesive layers, two of the auxiliary adhesive layers are symmetrically arranged and located at one end of the dressing body, and the other two auxiliary adhesive layers are symmetrically arranged and located at the other end of the dressing body.

[0010] Specifically, a plurality of slotted holes are also arranged on the dressing body.

[0011] The beneficial effects of the utility model are:

[0012] When using the dressing, according to the size and shape of the patient's wound, select the corresponding multiple inflatable cavities so that they exactly cover the wound, and use the inflation component to inflate them. Squeeze the corresponding balloon, and the air in the balloon enters the inflatable cavity through the inflation tube. Since there is a one-way valve in the inflation tube, the air enters the inflatable cavity and will not return to the balloon, causing the compression balloon to expand and compress the wound to stop bleeding; since there are multiple convex parts on one side of the compression balloon, the friction between the compression balloon and the dressing body is increased, so that the compression balloon is fixed; there are multiple arc surfaces on the other side of the compression balloon, and the arc surfaces gather the patient's wound and will not move as the compression balloon expands, avoiding wound cracking and causing secondary injuries; there are two symmetrical V-shaped grooves on the arc surface, which gather the patient's wound and at the same time increase the friction between the compression balloon and the gauze, so that the compression balloon is fixed. The dressing with the above structure can adapt to wounds of different sizes and shapes, prevent insufficient compression or excessive compression area, has a good compression effect, and is beneficial to the healing of the patient's wound.

[0026] The present disclosure will be described in detail below with reference to the drawings and in combination with embodiments.

[0027] Referring to Figures 1-6 As shown, a dressing with a local compression effect according to the utility model includes a dressing body 1, a gauze 2, and a compression mechanism 3. The gauze 2 and the dressing body 1 enclose a cavity 4. The gauze 2 is on the side close to the skin. The compression mechanism 3 is placed in the cavity 4. The compression mechanism 3 includes a compression airbag 31, a plurality of inflation cavities 32 arranged equidistantly in an array on the compression airbag 31, and a plurality of inflation components 33 respectively used to inject air into the plurality of inflation cavities 32. The inflation component 33 includes an inflation tube 34 fixedly arranged on the compression airbag 31 and communicated with the inflation cavity 32, a one-way valve 35 arranged inside the inflation tube 34, and a balloon 36 fixedly arranged at the other end of the inflation tube 34. The balloon 36 is communicated with the inflation tube 34.

[0028] When using the dressing, the dressing body 1 and the compression mechanism are made of transparent materials, which is convenient to select corresponding multiple inflatable cavities 32 according to the size and shape of the patient's wound, so that they exactly cover the wound. For example, when the patient's wound is L-shaped, corresponding multiple inflatable cavities 32 can be selected to make the multiple inflatable cavities in the corresponding L shape; use the inflation component 33 to inflate the multiple inflatable cavities 32, squeeze the corresponding balloon 36, and the air in the balloon 36 enters the inflatable cavity 32 through the inflation tube 34. Since a one-way valve 35 is provided in the inflation tube 34, the air enters the inflatable cavity 32 and cannot return to the balloon 36, and the compression balloon 31 expands to compress and stop bleeding the wound; the above structure of the dressing enables it to adapt to wounds of different sizes and shapes, prevents insufficient compression or excessive compression area, has a good compression effect, and is beneficial to the healing of the patient's wound.

[0029] Specifically, a plurality of convex portions 321 are provided on the side of the compression balloon 31 away from the skin. After the compression balloon 31 is inflated and expanded, the convex portions 321 increase the friction force between the compression balloon 31 and the dressing body 1, so that the position of the compression balloon 31 is fixed and will not move randomly with the movement of the patient, and the compression hemostasis effect is better.

[0030] Specifically, a plurality of arc-shaped surfaces 322 are provided on the side of the compression balloon 31 close to the skin. After inflation, the arc-shaped surfaces 322 gather the patient's wound and will not move with the expansion of the compression balloon 31, avoiding wound cracking and causing secondary injuries.

[0031] Specifically, two symmetric V-shaped grooves 323 are provided on the arc-shaped surface 322. The V-shaped grooves 322 gather the patient's wound and at the same time increase the friction force between the compression balloon 31 and the gauze 2, so that the position of the compression balloon 31 is fixed and the compression balloon 31 is prevented from shifting with the movement of the patient.

[0032] Specifically, adhesive layers 11 are provided at both ends of the dressing body 1 and a plurality of adaptation segments 12 are provided at equal intervals. When the dressing is applied to the patient's arm, the adaptation segments 12 make the dressing body 1 have better ductility and greater deformation degree; after the compression balloon 31 is inflated and expanded, the adaptation segments 12 enable the dressing body 1 to deform with the expansion of the compression balloon 31, preventing the dressing from exerting too much pressure on the patient's wound.

[0033] Specifically, the dressing body 1 is further provided with four auxiliary adhesive layers 13, two of the auxiliary adhesive layers 13 are symmetrically arranged and located at one end of the dressing body 1, and the other two auxiliary adhesive layers 13 are symmetrically arranged and located at the other end of the dressing body 1. The four auxiliary adhesive layers 13 can be rotated in different directions respectively to fix the dressing together with the adhesive layer 11 and prevent the dressing from falling off.

[0034] Specifically, the dressing body 1 is further provided with a plurality of slots 14 , which serve to give way. The compression airbag 31 can be slightly rotated in the slots 14 to cover wounds at different angles, thereby achieving a better compression effect.

[0035] The above descriptions are only some preferred embodiments of the present disclosure and an explanation of the technical principles used. Those skilled in the art should understand that the scope of the utility model involved in the embodiments of the present disclosure is not limited to the technical solutions formed by the specific combination of the above-mentioned technical features, but should also cover other technical solutions formed by any combination of the above-mentioned technical features or their equivalent features without departing from the above-mentioned utility model concept. For example, the above-mentioned features are replaced with the technical features with similar functions disclosed in the embodiments of the present disclosure (but not limited to) to form a technical solution.
