An apparatus and method for generation of a protective sleeve against infections for a percutaneous lead through human or animal skin. The percutaneous lead (1) includes an extrusion port (7). When the lead extends through a body (3) of a patient, a pump (9) in operative connection with the lead is operative to move biocompatible liquid polymer material from a reservoir (10) through the extrusion port. As the polymer material comes in contact with body tissues of the patient it forms a protective sleeve against infections (5). The protective sleeve must be periodically clipped as it continuously or intermittently grows in an upward direction (6) outside of the body. The continual formation of the protective sleeve prevents the formation of a biofilm on the percutaneous lead that can cause the body tissue to separate from the percutaneous lead.

The invention discloses a method for preparing collagen oligopeptide. Animal skins are taken as raw materials, and are subjected to acid and surfactant pretreatment, enzymolysis, decoloration, membrane separation and drying to form the collagen oligopeptide. The relative molecular weight of the prepared collagen oligopeptide is mainly distributed below 1,000Dalton, and preferably, the Gaussian distribution peak area percentage of oligopeptide with the relative molecular weight of less than 1,000Dalton is over 85 percent and preferably over 90 percent. The method solves the general problems that the conventional collagen products have odor, are dark yellow and the like; and the obtained collagen oligopeptide powder is white, free of odor and good in mouthfeel, has high absorptivity and penetrability and can be widely applied to the cosmetics industry, the food industry and the like.

A long-lasting persistent, uniform film-forming skin protecting germicidal composition provides a long-lasting persistent barrier film when applied to skin. The compositions have particular utility as barrier teat dips for protecting cows against mastitis. A barrier film-forming agent is selected from the modified or hydrolyzed polysaccharides, particularly a hydrolyzed or modified starch, such as dextrin and maltodextrin. The barrier film-forming agent is stably solubilized in a solvent that dries to form the long-lasting persistent uniform film over the animal skin. The compositions also contain antimicrobial agents that fight against microbes that manage to penetrate the protective barrier film. Particularly, advantageous is that all the materials used are safe food additive and cost effective over the traditional barrier film forming agents.

A semi-flexible insecticide strip is removably attached to the belt of a pelt collar to regenerate a pest-killing medicament and increase its efficacy. The strip is secured to the belt surface that faces the animal skin or fur by attachment loops or edged retainers that are generally perpendicular to the length direction of the belt. Due to the geometry and elasticity of the semi-flexible insecticide strip, and its attachment method, the strip contacts the skin or fur of the animal despite movement of the pet collar when the animal is being exercised with a pet leash attached thereto. The contact effectively transfers the insecticide and kills ticks and fleas or retards development of mature flea adults. The insecticide is contained within a plurality of plastic pores of the insecticide strip or in a sponge affixed thereto.
