Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of transdermal patch, especially to a transdermal patch in-vitro test processing device. BACKGROUND

[0002] As an important drug delivery method, transdermal patch has been widely used in the medical field in recent years. Transdermal patch can make the drug penetrate the skin into the blood circulation at a relatively constant rate, avoiding the problems of gastrointestinal degradation and liver first-pass effect that may be faced by oral administration, and also has the advantages of improving patient compliance, etc.

[0003] In the research and production process of transdermal patch, the adhesion of transdermal patch needs to be strictly tested and evaluated. The traditional detection method is mostly through simple manual operation, such as directly peeling off the transdermal patch by hand to judge its adhesion. This method has great subjectivity. Different operators may draw different conclusions about the adhesion of transdermal patch due to differences in force, peeling angle, etc. If the operator makes a mistake, the transdermal patch with poor adhesion may be misjudged as a qualified product, which may easily fall off prematurely during the subsequent use of the patient, not only interfering with the normal delivery of the drug at the expected rate and dose, but also possibly greatly reducing the treatment effect and failing to achieve the expected treatment purpose. SUMMARY

[0004] To solve the above technical problems, the utility model provides a transdermal patch in-vitro test processing device.

[0005] The utility model adopts the following technical scheme: a transdermal patch in-vitro test processing device, including the workbench, the upper surface of the workbench is fixedly connected with the test peeling plate, the upper surface of the test peeling plate is bonded with the transdermal patch body, the upper surface of the workbench is equipped with the side groove, the inside of the side groove is connected with the extension block in sliding mode, the surface of the extension block is fixedly connected with the push frame, the surface of the push frame is fixedly connected with the adhesive roller, the upper surface of the workbench is fixedly connected with the support frame, the surface of the support frame is fixedly connected with the drive mechanism.

[0006] Through the above technical scheme, the adhesion of different transdermal patch bodies can be directly compared, the transdermal patch bodies with poor adhesion can be classified and processed, the product quality is improved, and the problem of easy falling off caused by using transdermal patch with poor adhesion is avoided.

[0007] As a further improvement of the above scheme, the drive mechanism includes a sliding groove plate, the upper surface of the sliding groove plate is fixedly connected with a drive motor, the output end of the drive motor is fixedly connected with a lead screw, the surface of the lead screw is threadedly connected with a limit sliding frame, and the surface of the lead screw is rotatably connected with a support shaft seat.

[0008] The above technical solution drives the movement of the limiting slide, thereby providing power for the linear movement of the pusher and ensuring a stable and orderly peeling process of the transdermal patch.

[0009] As a further improvement to the above solution, the slide plate is fixedly connected to the surface of the support frame.

[0010] The above technical solution enables the drive mechanism and the support frame to form a stable connection structure, which helps to maintain the integrity of the entire device structure and prevents malfunctions due to structural instability during the peeling process of the transdermal patch.

[0011] As a further improvement to the above solution, the limiting slide is fixedly connected to the surface of the pusher frame, and the limiting slide is slidably connected to the inside of the slide plate.

[0012] The above technical solution enables the adhesive roller to move along a predetermined trajectory, ensuring the accuracy of the transdermal patch peeling operation.

[0013] As a further improvement to the above solution, the support shaft seat is fixedly connected to the upper surface of the slide plate.

[0014] The above technical solution enhances the stability of the lead screw rotation, thereby ensuring the smooth peeling of the transdermal patch.

[0015] As a further improvement to the above solution, the transdermal patch body is adhered to the surface of the adhesive roller.

[0016] The above technical solution enables the adhesive roller to effectively drive the transdermal patch body to peel off.

[0017] As a further improvement to the above solution, a control panel is fixedly connected to the surface of the workbench.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0019] This invention uses a drive motor to rotate a lead screw, causing a limiting slide to move linearly along a slide rail. The limiting slide then drives a pusher frame, on which the adhesive roller moves accordingly. Due to the adhesion between the transdermal patch, the adhesive roller, and the test peel plate, the adhesive roller moves one side of the transdermal patch, peeling it off from the test peel plate. When the adhesive roller simultaneously peels off three different transdermal patches, the patch with the weakest adhesion will be the first to lift up. This allows for direct comparison, enabling the categorization and processing of the poorly adhesive patches, thus improving overall product quality and preventing users from easily detaching the patch due to poor adhesion.
