AI Technical Summary

Benefits of technology

This patented technology describes various technical features related to this type of medical equipment called vacuum sealed drainaging systems. These systems have several benefits over current methods like surgery, including ease of handling, reduced risk of complications due to exposure to bloodborne pathogens, improved safety measures, easier placement without damming important organs near them, lower costs compared to traditional techniques, and enhanced usability. Additionally, these systems provide flexibility because they allow users to adjust their settings easily while still being able to effectively treat patients undergoing treatment.

Problems solved by technology

This technical problem addressed in this patents relates to developing better ways to treat body surfaces without causing contaminations while minimizing discomfort experienced after prolonged procedures. Existing techniques involve applying vacuum therapy over several hours before removing any obstructive material around the affected areas. These current techniques have drawbacks including poor sealing efficiency, potential gas leaks, difficulty in attaching thin layers onto the skin, and lack of effective securability.

Abstract

The invention relates to a negative pressure closed drainage device, comprising a porous foam cushion (1), a drainage tube (2) with a side hole, a joint (4), a conduit (11), a drainage container (5) and a negative source (6). The drainage tube (2) is connected with the conduit (11) which is led into the drainage container (5), and the drainage container (5) is connected with the negative pressure source (6). One end of the drainage tube (2) is positioned in the porous foam cushion (1), and the other end of the drainage tube (2) is led out from the upper end of the porous foam cushion (1). The leading-out end of the drainage tube (2) is fixed with an adhesive film (7), and a sealing film (3) is sealed on the adhesive film (7). The invention overcomes the defects that the traditional negative pressure closed drainage device is inconvenient, a better carrier used as a support is not available when the sealing film is sealed, and a drainage device for a wound surface on the body surface is very inconvenient to use when carrying out negative pressure sealing drainage. The negative pressure closed drainage device for the wound surface tissue on the body surface has the advantages of suitability for the drainage of the wound surface on the body surface, suitability for the drainage in a body cavity and more convenient film sticking.
