The present application belongs to the technical field of medical hemostatic dressings and bandages, and particularly relates to a Duyuwei emergency hemostatic bandage, which comprises a bandage main body, the bandage main body is composed of a tight band and a dressing pad, the dressing pad is fixed to the front end of the tight band, the dressing pad is composed of an absorption area, a tablet area and a pad base layer, the absorption area and the tablet area are fixed on the pad base layer by traditional Chinese medicine glue, the absorption area is composed of Duyuwei gelatin sponge, the tablet area is composed of Duyuwei external-use tablets, and the pad base layer is composed of a medical degreasing cotton pad. A preparation method of the Duyuwei emergency hemostatic bandage comprises the following steps: Duyuwei medicinal material decoction piece component extraction, Duyuwei external-use tablet preparation, traditional Chinese medicine glue preparation, Duyuwei gelatin sponge preparation and Duyuwei hemostatic bandage preparation. The present application has the advantages of rapid hemostasis and remarkable efficacy: the Duyuwei extract, the gelatin sponge and the traditional Chinese medicine glue synergistically act to significantly shorten the hemostasis time. Animal experiments show that the average hemostasis time is short.

The invention relates to the technical field of nursing materials, and discloses eye washing liquid for relieving eye fatigue and a preparation method thereof.The eye washing liquid is prepared from trehalose, taurine, sodium gualenate, sodium hyaluronate, ergothioneine, vitamin B12, vitamin B6, xanthophyll, mint, a humectant, a bacteriostatic agent, a chelating agent, a pH regulator and deionized water. Through the synergistic effect of the first synergistic composition and the second synergistic composition, retina cell injury induced by blue light can be effectively repaired, the repairing effect is superior to that of simple addition of a single component, blue light oxidative injury is repaired through a multi-target synergistic mechanism, a three-layer structure of a tear film lipid layer, a water layer and a mucoprotein layer can be reconstructed, and the repairing effect is good. According to the present invention, the tearable film stability is significantly improved, the excellent protection and repair effect is provided, the compatibility of the components is good, the product stability is high, and the multiple effects of ocular surface cleaning, asthenopia relieving, conjunctival congestion reducing and blue light oxidation damage preventing are provided.

This invention relates to the field of silicone rubber materials technology, and discloses a high-transparency biocompatible material for endoscope-assisted water bags and its preparation method. The raw materials for this invention's high-transparency biocompatible material for endoscope-assisted water bags include 80-90 parts by weight of α,ω-dihydroxypolydimethylsiloxane, 10-20 parts by weight of silanol polylactic acid, and 0.04-0.07 parts by weight of catalyst, etc. This invention uses non-toxic and non-irritating silicone rubber and highly biocompatible polylactic acid as the matrix, which is non-irritating to the human body. The prepared material is suitable for use in medical devices such as endoscope-assisted water bags. The improved interfacial properties and compatibility between polylactic acid and α,ω-dihydroxypolydimethylsiloxane reduce the likelihood of interfacial defects, maintaining good light transmittance, tensile strength, and elongation at break. When used as an endoscope-assisted water bag, it allows for better observation, and polylactic acid imparts good biodegradability to the silicone rubber material.

The invention discloses an automatic telescopic child stomach tube device capable of preventing abdominal distension and regurgitation under noninvasive ventilation. The device is used for preventing abdominal distension of a child patient under noninvasive ventilation. A nasal gastrointestinal tube head, a controller, an automatic breathing machine airflow blocker, a stomach tube body and a supporting strip form a whole, the automatic breathing machine airflow blocker is fixed to the upper middle portion of the stomach tube, in the process of using the stomach tube, medical workers place the stomach tube with the automatic breathing machine airflow blocker into the stomach through the esophagus of a child patient, and the stomach tube with the automatic breathing machine airflow blocker is fixed to the upper middle portion of the stomach tube. After the controller is pressed down, the airflow blocker of the automatic breathing machine fills the gap between the stomach tube and the esophagus, the situation that airflow enters the stomach through the esophagus to cause abdominal distension of a child patient in the application process of the non-invasive breathing machine is avoided, meanwhile, the influence of gastric regurgitation on the child patient is prevented, and therefore the situation that feeding of the child patient is affected by non-invasive ventilation is prevented.

This invention provides a transdermal follicular delivery system for active ingredients based on a protein carrier. The system comprises a composite structure of a small molecule active ingredient, a bioactive protein, and a polymer shell, with a size of 40-150 nm and a polymer shell thickness of 10-70 nm. The zeta potential of this protein carrier-based transdermal follicular delivery system is positively charged. The small molecule active ingredient is loaded within the bioactive protein, and the polymer shell coats the bioactive protein to form a protein nanogel. Both the small molecule active ingredient and the bioactive protein have beneficial effects on hair follicles. When this transdermal follicular delivery system is applied to the surface of a hair follicle or skin, the functional small molecules are delivered transdermally along with the nanogel to the interior of the hair follicle and surrounding tissues, where they are released in a controlled manner, thus effectively exerting their effects.
