The utility model discloses following beneficial effect has: 1. the structure is simple, the operation is convenient, and the plaster bandage is not required to be folded in advance; 2. the lining is breathable and conformable, and the body feeling is comfortable; 3. the gypsum is externally provided with a shaping layer, so that the influence on the hardness of the gypsum caused by the fact that the gypsum is soaked in the domestic water can be prevented.

Description

Integrated gypsum

Technical Field

The utility model relates to a medical gypsum structure specifically is a gypsum of integration, belongs to medical instrument technical field.

Background

The plaster fixation technique is one of the most commonly used treatments in orthopedics. The existing gypsum fixing technology realizes the toughness fixation of gypsum by combining gypsum powder and a fiber net and combining the hardness of the gypsum and the softness of the fiber net. The current clinical operation process mainly comprises the following steps: firstly, the plaster bandage is folded into a plurality of layers of rectangular strips with certain length, then the strips are soaked in water, the plaster powder is changed into plaster liquid, the plaster form is convenient to change, the requirement of attaching to the limb is realized, finally, the plaster strips are placed on the surface of the limb covered with the lining for fixing the plaster bandage, and after the plaster is heated and fixed, the plaster bandage fixing operation is completed. However, the current plaster bandages have the following problems: 1. the operation process is complex, and the plaster bandage needs to be folded into rectangles with different lengths in advance; 2. the inner lining has poor air permeability and hydrophobicity, and the patient experience is poor; 3. the gypsum is ugly in shape; 4. the gypsum cannot touch water, which would otherwise affect the gypsum hardness.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing an integrated gypsum to solve the above-mentioned problem of prior art.

The purpose of the utility model is realized by the following technical scheme.

An integrated gypsum is of a laminated structure and comprises a flexible inner lining layer in contact with a human body limb and a hard shaping layer matched with the outline of the human body limb, wherein the shaping layer can be coated and shaped according to the shape of the patient limb and maintains a fixed shape, a fiber mesh is arranged in a cavity between the shaping layer and the inner lining, and liquid gypsum can be quickly poured in the fiber mesh and solidified; a gypsum liquid feeding hole is formed in the plastic layer; the gypsum liquid enters the cavity from the feeding hole and fills the cavity, and is mixed with the fiber grids and then solidified to form a gypsum layer.

The inner liner layer is one of an air bag, a water bag or a material with air permeability and hydrophobicity.

The gypsum layer realizes the toughness of the gypsum in different degrees by adjusting the proportion of the gypsum and the fiber meshes; forming gypsum models with different specifications.

The edge swing joint of inner liner and moulding layer, can be for dyestripping structure, joint structure or nylon fastener structure.

The inner liner on be equipped with pressure sensor and alarm, lead to the swelling because of limbs fracture for the pressure increase between gypsum and the limbs, report to the police when pressure sensor detects pressure and reaches the threshold value.

The plastic layer is made of polyurethane material or other high polymer materials; can be smeared and shaped according to the limb shape of a patient and maintain a fixed shape.

The shaping layer has certain hardness and is used for shaping and fitting the surface of the limb of the human body; the shape can be maintained before the gypsum is cured after the gypsum is added; hydrophobicity and beautiful appearance.

The utility model discloses following beneficial effect has: 1. the structure is simple, the operation is convenient, and the bandage is not required to be folded in advance; 2. the lining is breathable and conformable, and the body feeling is comfortable; 3. the gypsum is externally provided with a shaping layer, so that the influence on the hardness of the gypsum caused by the fact that the gypsum is soaked in the domestic water can be prevented.

Drawings

Fig. 1 is a schematic structural view of the present invention;

in the figure, 1, an inner liner; 2. a shaping layer; 3. a gypsum layer; 4. fiber mesh; 5. gypsum liquor; 6. a feed inlet; 7. a sensor.

Detailed Description

The technical features of the present invention will be further explained with reference to the accompanying drawings and specific embodiments.

The integrated plaster shown in fig. 1 is a layered structure, and comprises a flexible inner liner layer 1 contacting with limbs of a human body, and a hard shaping layer 2 matching with the outer contour of the limbs of the human body, wherein a fiber grid 4 is arranged in a cavity between the shaping layer 2 and the inner liner layer 1; a gypsum liquid feeding port 6 is formed in the plastic layer 2; the gypsum liquid enters the cavity from the feeding hole 6 and fills the cavity, and is mixed with the fiber grids 4 and then is solidified to form the gypsum layer 3.

The inner liner layer 1 is one of an air bag, a water bag or a material with air permeability and hydrophobicity.

The gypsum layer 3 realizes the toughness of the gypsum in different degrees by adjusting the proportion of the gypsum and the fiber meshes; forming gypsum models with different specifications.

The edge swing joint of inner liner 1 and moulding layer 2, can be for dyestripping structure, joint structure or nylon fastener structure.

The inner liner layer 1 on be equipped with pressure sensor 7 and alarm, lead to swelling because of limbs fracture for the pressure between gypsum and the limbs increases, reports to the police when pressure sensor 7 detects pressure and reaches the threshold value.

The shaping layer 2 has certain hardness and is used for shaping and fitting the surface of the limb of the human body; the shape can be maintained before the gypsum is cured after the gypsum is added; hydrophobicity and beautiful appearance.
