The present invention relates to a wound dressing material comprising a fibrillated acellular dermis matrix and a biodegradable polymer aqueous solution and, more specifically, to: a wound dressing material comprising 5-20 wt % of a fibrillated acellular dermis matrix, 0.5-5 wt % of a biodegradable polymer, and 75-94.5 wt % of water; and a preparation method therefor.

Wound dressing material comprising fibrillated accellular dermis matrix and biodegradeable polymer, and preparation method therefor

The present invention relates to a wound volume measuring method and device, wherein the method comprises the steps of: disposing a foam dressing on a wound site; hermetically sealing the wound site by attaching a film dressing on skin adjacent to the wound site; supplying a negative pressure to the hermetically sealed space formed between the film dressing and the wound site, and thereby discharging fluid into the hermetically sealed space; measuring the flow of the fluid discharged from the hermetically sealed space; and calculating the volume of the wound site on the basis of the measured fluid flow.

Provided is a portable vacuum generator that can effectively save battery power of a vacuum pump for absorbing exudates from a suction head that is connected to a tube, and a medical suction device using the same. The medical suction device includes: a connection tube whose one end is connected to a connector of the suction head; and a vacuum generator including a vacuum pump that is connected to the other end of the connection tube and having a motor for generating negative pressure, and a vacuum pump controller that controls a power supply for the vacuum pump so as to maintain a vacuum state, in which the vacuum pump controller blocks the power supply for the vacuum pump until pressure of the vacuum pump falls down to preset minimum pressure in the case that the current pressure that is applied to the vacuum pump reaches preset maximum pressure, and drives the vacuum pump until pressure of the vacuum pump reaches the preset maximum pressure in the case that the current pressure falls down to the preset minimum pressure.

The present invention relates to a nanoliposome comprising a liposome membrane containing esterified lecithin, and one or more physiologically active ingredients included in inner space of the liposome membrane; a method for preparing the same; and a composition for preventing or treating skin diseases, comprising the same. The nanoliposome according to the present invention has long-term stability and uniformity, and so can be used to prepare a composition for skin having excellent moisturizing and penetrating properties, such as cosmetics, medicament for treating skin diseases, or the like. In particular, the present composition for preventing or treating skin diseases comprises epidermal growth factor included in the nanoliposome, thereby showing an excellent effect of stimulating skin-penetration and good pharmaceutical stability. Also, the esterified lecithin used in preparing liposome can provide effects of softening skin and stimulating skin-penetration, thereby enhancing the penetration of epidermal growth factor and natural extract into skin, as well as additional moisturizing effect which is advantageous in treating skin diseases. Further, since the present composition comprises nanoliposome prepared by containing esterified lecithin in liposome membrane, the conventional problems of heating and dispersing active ingredients at high temperature (70&#xb0; C. or more), low stability and uniformity, or the like can be solved.
