Embodiment 1

[0025] Such as Figure 1-4 As shown, this embodiment provides a color-changing and visible dressing. The dressing is a flat structure, and its longitudinal section structure includes four layers from the outside to the inside. , endogenous substance discoloration layer 3, dressing inner layer 4; the lateral shape of the exogenous substance discoloration layer 1 is a quadrilateral hollowed out in the middle; the lateral shape of the transparent layer 2 is a quadrilateral with the same size as the exogenous substance discoloration layer 1 but with a protruding middle , the protruding part in the middle of the transparent layer 2 is closely attached to the hollow part in the middle of the exogenous color-changing layer 1; the lateral shape of the endogenous color-changing layer 3 is a quadrilateral slightly smaller than the size of the exogenous color-changing layer 1 and protruding in the middle ; The lateral shape of the dressing inner layer 4 is a quadrilateral with the same s...

Embodiment 2

[0031] Such as Figure 5-8 As shown, this embodiment provides a dressing that changes color and is visible. The dressing is a flat structure, and its longitudinal section structure includes five layers from the outside to the inside. 21. Transparent isolation layer 22, endogenous substance discoloration layer 3, and dressing inner layer 4; the lateral shape of the exogenous substance discoloration layer 1 is a quadrilateral hollowed out in the middle; the lateral shape of the transparent observation layer 21 is the same size as the exogenous substance discoloration layer 1 Consistent but protruding quadrilaterals in the middle, the protruding part in the middle of the transparent observation layer 21 is closely attached to the hollow part in the middle of the exogenous color changing layer 1; the lateral shape of the transparent isolation layer 22 is consistent with the size of the exogenous color changing layer 1 Quadrilateral; the lateral shape of the endogenous discoloratio...

Abstract

The invention provides a color-changing visible wound dressing. The dressing is of a flat structure, and the longitudinal section structure of the dressing sequentially comprises at least four layersof structures from outside to inside, namely an exogenous substance color-changing layer, a transparent layer, an endogenous substance color-changing layer and a dressing inner layer. The wound dressing is particularly suitable for postoperative wounds after lumbar cistern drainage, a wound pollution condition can be reflected more visually, wound dressing pollutant sources (cerebrospinal fluid, urine, sweat and the like) can be found as soon as possible, family members of patients or nurses can find pollution in time and treat the pollutant sources in time, intracranial infection risks are reduced, and the risk of complications of the patients is greatly reduced.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a wound dressing that changes color and is visible. Background technique [0002] Lumbar cerebrospinal fluid drainage (LCFD) refers to a closed and sterile technique that continuously drains cerebrospinal fluid from the subarachnoid lumbar cistern to the outside of the body. Lumbar cistern drainage is widely used in the field of neurosurgery. Its advantages are minimally invasive, airtight, stable pressure, and adequate drainage of cerebrospinal fluid. It can better control the drainage speed of cerebrospinal fluid, slowly reduce intracranial pressure, relieve cerebral vasospasm, and reduce meningeal irritation to prevent the occurrence of hydrocephalus, but there are still complications such as low intracranial pressure, pneumothorax, unsmooth drainage tube, intracranial infection, intracranial hemorrhage, and cerebrospinal fluid leakage at the puncture site. The cause...
