Description

Technical Field

[0001] The present invention relates to the technical field of medical dressings, and more specifically to a hydrogel dressing patch, a manufacturing device and a manufacturing process thereof. Background Art

[0002] Hydrogel dressing patch is a kind of medical dressing, which is mainly made of hydrogel material. Hydrogel is a cross-linked polymer that can swell in water and retain a large amount of water without dissolving in water. It has a unique three-dimensional network structure. This structure enables the hydrogel dressing patch to absorb and retain exudate on the surface of the wound, while maintaining a moist environment for the wound, which helps promote wound healing. Hydrogel dressing patches are widely used in the treatment of various wounds, including burns, scalds, surgical wounds, skin lacerations, chronic wounds (such as diabetic foot ulcers, pressure sores), etc. They can not only promote wound healing, but also reduce scar formation and relieve patients' pain.

[0003] Most hydrogel dressings on the market are currently produced in larger standard sizes. However, in actual applications, patients' wounds vary in size and shape, which requires users to cut the dressings themselves before use to suit the actual needs of the wound. This cutting process not only increases the user's operating difficulty and time cost, but may also cause the dressing to fail to fit the wound tightly due to improper cutting, thus affecting its use effect.

[0004] Moreover, for wounds that need to be medicated, when existing hydrogel dressings are attached to wounds, the drugs often reduce the adhesion of the hydrogel. This is because the drug overflow reduces its adhesion to the wound surface, causing the dressing to fall off easily during use. Once the dressing falls off, it will not only cause the drug to leak out, affecting the treatment effect, but may also increase the risk of wound infection.

[0005] In addition, the existing production equipment for hydrogel dressings has certain limitations in efficiency and function. On the one hand, the production efficiency is low and cannot meet the needs of large-scale production; on the other hand, the function is single and it is impossible to produce hydrogel dressings with special shapes, sizes or functions. These problems limit the further application and development of hydrogel dressings in the field of medical care.

[0006] In summary, the existing hydrogel dressing patch still has many shortcomings during use, including inflexible size, reduced adhesion due to drug coating, low efficiency of production equipment and single function. In view of this, we propose a hydrogel dressing patch, a manufacturing device and a manufacturing process thereof. Summary of the invention

The deviation correction block is arranged at the bottom end of the hydrogel raw material, and the deviation correction of the hydrogel raw material is achieved by controlling the servo motor B to prevent the deviation from causing production errors;

[0026] S3, adjustment operation;

[0027] S3.1. Select the specific tool usage state according to the shape of the processed hydrogel dressing patch. If it is necessary to make a long strip of hydrogel dressing patch, first drive the servo motor A to drive the worm to rotate, the worm drives the worm wheel to rotate, the worm wheel is fixedly connected to the rotating disk to drive it to rotate synchronously on the end shaft body, the rotation of the rotating disk causes the eight curved grooves to rotate synchronously, when the rotating disk rotates counterclockwise, the rotating disk causes the limit rod A to move in the curved groove, the limit rod A drives the plug plate A to move on the slide groove, because the plug plate A is fixedly connected with a blade plate, the blade plate moves outward on the linear groove until it extends out of the linear groove, the rotating disk synchronously causes the limit rod B to move in the curved groove, the limit rod B drives the plug plate B to move on the slide groove, because the plug plate B is fixedly connected with a slice block, the slice block moves outward on the sheet-shaped groove until it fits with the sheet-shaped groove to form an outer wall;

[0028] S3.2. Select the specific tool usage state according to the shape of the processed hydrogel dressing patch.

When the rotating disk rotates clockwise, the rotating disk causes the limit rod A to move in the curved groove, and the limit rod A drives the plug plate A to move on the slide groove. Since the plug plate A is fixedly connected with a blade plate, the blade plate moves inward on the linear groove until it fits with the linear groove to form an outer wall.

[0032] 1. The present invention improves the structure of the existing hydrogel dressing patch, opens a drug retention portion on the hydrogel body of the dressing patch body, and retains the drug liquid applied to the wound in the diffusion groove through the diffusion groove for uniform drug release. Several semi-ellipsoidal retention grooves opened inside the diffusion groove store part of the drug liquid in the semi-ellipsoidal cavity. Due to its flat shape, the outflow speed of the drug liquid is slowed down to a certain extent, thereby achieving the effect of continuous drug administration.

[0033] 2. The present invention also arranges a discharge shaft on the base platform, and transports the hydrogel raw material to the circular knife module mechanism for production through the driving mechanism and the discharge shaft. The circular knife module mechanism mode is switched to process and produce strip hydrogel dressing patches and sheet hydrogel dressing patches, thereby meeting the production needs of hydrogel dressing patches of different shapes, reducing the time required for replacing or adjusting equipment, and thus improving the overall production efficiency.

[0034] 3. In the present invention, the servo motor A is driven to rotate the worm, which drives the worm wheel to rotate. The worm wheel is fixedly connected to the rotating disk to drive it to rotate synchronously on the end shaft body. The rotation of the rotating disk causes the eight curved grooves to rotate synchronously. The curved grooves drive the strip cutting assembly and the sheet cutting assembly to move, thereby realizing the switching of the shapes. Since the worm and the worm wheel have relatively good self-locking properties, the positions of the strip cutting assembly and the sheet cutting assembly are self-locked and fixed after switching to prevent loosening or falling off.

[0035] 4. In the present invention, a mounting frame is symmetrically provided on one side of the circular knife module mechanism close to the discharge axis, a carrier frame is connected between the two mounting frames, a servo motor B is provided on the outer side of the carrier frame to drive the servo motor B to operate, and the output end of the servo motor B is connected to a reciprocating screw rod so that the reciprocating screw rod rotates inside the carrier frame. Since the correction block is symmetrically provided with stabilizing rods and stabilizing grooves are symmetrically opened inside the carrier frame, the rotation of the reciprocating screw rod drives the correction block adapted thereto to reciprocate, and the stabilizing rod slides back and forth in the stabilizing groove to achieve a stabilizing effect. The correction block is arranged at the bottom end of the hydrogel raw material, and the correction of the hydrogel raw material is achieved by controlling the servo motor B to prevent production errors caused by offset.
