Description

Technical Field

[0001] The utility model relates to the technical field of hydrogel preparation, in particular to a restrictive water loss device for processing a hydrogel patch. Background Art

[0002] Myocardial infarction is one of the most common causes of morbidity and mortality worldwide. Once it occurs, it can cause damage to the structure and function of myocardial cells, leading to changes in the electrophysiological and mechanical properties of the myocardium. In addition, necrotic myocardial cells will gradually be replaced by scar tissue that lacks conductivity and elasticity. Scar tissue divides normal myocardial cells, causing myocardial electrical signal conduction block and contraction asynchrony, leading to impaired cardiac pumping function and the occurrence of arrhythmias.

[0003] Since adult cardiomyocytes are non-regenerative, tissue engineering methods can be used to design a hydrogel patch that can adhere to the surface of the heart and repair cardiac function by providing mechanical assistance to the infarcted myocardial area and restoring its electrical conductivity. The patch uses high molecular conductive polymer poly-3-thiophene acetic acid and photosensitive hydrogel methacrylated gelatin. Through 3D printing technology, double network hydrogel synthesis technology and restricted water loss technology, it has good biocompatibility and anisotropic mechanical and electrical properties similar to normal myocardium. 3D printing and double network hydrogel one-step synthesis technology realize the rapid preparation of conductive patches. The restricted water loss method generates a directional fiber structure similar to myocardial fibers inside the hydrogel material, giving the patch anisotropic mechanical and electrical properties close to myocardial tissue. After obtaining a patch of the desired thickness and shape through 3D printing, the hydrogel patch needs to be subjected to restricted water loss treatment. In current technology, the hydrogel patch is usually clamped and fixed directly using a clamp, and then placed under constant temperature and humidity conditions, and removed after a period of time to complete the water loss treatment. The method of directly clamping and fixing the hydrogel patch with a clamp has the problem of difficulty in controlling the clamping force. If the clamp is too tight, the hydrogel patch may be easily damaged, and if the clamp is too loose, the hydrogel patch may easily fall off. Utility Model Content
