Problems solved by technology

[0005] However, there are still many problems in the existing VSD technology: ①The sealing is inconvenient, and the seal between the sealing film and the part through which the drainage tube passes is not tight
③It is difficult to seal when the external fixator is inserted into the needle or the perineal cannula is intubated

Embodiment Construction

[0032] Embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, but they do not constitute a limitation of the present invention.

[0033] figure 1 It is a schematic diagram of the overall structure of the first most basic negative pressure sealing drainage device of the present invention:

[0034] It includes a porous foam cushion 1, a drainage tube 2 arranged in the porous foam cushion 1, and the tail end protrudes outside the porous foam cushion 1, and an elastic sealing film is provided on the outside of the porous foam cushion 1 3. There is a sealing port 3a protruding from the drainage tube 2 on the elastic sealing film 3, and the sealing port 3a is a round hole.

[0035] Figure 4 It is a schematic diagram of the elastic sealing film: the diameter D of the sealing hole 3 a is 0.3-4 mm smaller than the outer diameter of the corresponding drainage tube 2 .

[0036] Due to the elasticity of the elastic sealing...

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.

Description

technical field [0001] The invention relates to a medical negative pressure sealing drainage device. It is a negative pressure sealing drainage suitable for the treatment of human body surface tissue or body cavity lesions. Background technique [0002] Vacuum sealing drainage technology (vacuum sealing drainage, referred to as VSD) was pioneered by Dr. Wim Fleischman of ULM University in Germany in 1992, and formed a theoretical prototype for the drainage of extremity wounds; in 1994, Professor Qiu Huade of China applied the vacuum sealing drainage technology for the first time In general surgery, pioneered the application of negative pressure sealing drainage technology in general surgery. The patent CN 2236350 authorized by Professor Wang Yanfeng and Qiu Huade in China on March 17, 1997 was the first patent of negative pressure sealing drainage technology. [0003] The basic configuration of existing VSD technology includes negative pressure source (including medical suc...
