3results about How to "Achieve hemostatic effect" patented technology

The utility model discloses a hemostatic cap for ear-nose-throat surgery, and relates to the technical field of ear-nose-throat surgery appliances, the hemostatic cap comprises a cap body, an expansion element and a pressure measuring element, the cap body comprises a hood part used for covering and wrapping the head of a patient and a binding part used for covering the lower jaw and the neck of the patient, when the binding part is tensioned, the cap body can be fixed to the head of a patient, the expansion element is installed on the inner side of the cap body, the expansion element can be inflated to expand and deflated to contract, the expansion element can be attached to and press the wound part of the head and neck of the patient when inflated to expand, and the pressure measuring element is installed on the cap body. The detection end of the pressure measuring element extends to the expansion element, and the pressure measuring element is used for detecting and displaying the pressure in the expansion element. According to the hemostat, the compression force applied to the wound part of a patient can be constant, and effective hemostasis is achieved.

The utility model discloses a detachable conductive hemostatic trocar device, including the tubulature, the tubulature and human body cooperation one end intercommunication connection has the extension pipe, the extension pipe is away from the tubulature one end for sharp end and the extension pipe's outside detachable cover has the conductive ring, and, the tubulature is away from the extension pipe one end and is provided with the conductive interface and the tubulature is embedded and is provided with the conductive passage along its length direction, the both ends of conductive passage are electric connection with conductive ring, conductive interface respectively, and, the extension pipe is away from the tubulature one end and is provided with visible module, visible module and external display wired or wireless connection. The utility model has the advantages of adjustable conductive contact area, can effectively improve hemostatic effect and the operating safety and efficiency.

The invention discloses an antibacterial hemostatic bandage and a preparation method thereof, and relates to the technical field of medical supplies. When preparing the antibacterial hemostatic bandage, the present invention first performs surface modification of nano zinc oxide with organosiloxane to obtain modified nano zinc oxide; chitosan is reacted with D, L-lactide to obtain grafted polylactic acid chitosan; grafted polylactic acid chitosan is first reacted with chloroacetyl chloride, and then with oil-based dimethyl tertiary amine to obtain hydrophobically modified chitosan; hydrophobically modified chitosan, modified nano zinc oxide, and vinyl polysiloxane are prepared into a dispersion in dichloromethane, sprayed on a polypropylene non-woven fabric, and immersed in a ferric chloride solution after irradiation cross-linking, and an antibacterial hemostatic bandage is obtained after drying. The antibacterial hemostatic bandage prepared by the present invention has a faster hemostatic speed, good antibacterial property, low blood loss rate, and is easy to remove when replaced due to the surface super-hydrophobicity, reducing secondary injury and secondary bleeding.
