Problems solved by technology

When the polyvinyl alcohol foam built-in drainage tube system is used clinically, the operation of the medical sealing film is complicated, and professional training and long-term practical operation experience are required to effectively solve various problems in clinical application; at the same time, the built-in drainage tube is Under the action of negative pressure, the wound surface is pressed with a certain force, leaving a white mark of the drainage tube on the wound surface, and the patient's user experience needs to be improved; moreover, the irrigation pipeline is attached to the drainage pipeline, and can only be flushed in the pipeline. Instead of realizing the wound washing desired by the medical staff
When the polyurethane foam external suction cup system is used clinically, although the operation of the medical sealing film is relatively simple and there is no indentation, the drainage effect of the suction cup is worse than that of the built-in drainage tube, and the flushing pipeline is attached to the suction cup, so only the suction cup can be realized. Flush in the pipeline with the suction cup, can not achieve wound flushing

Embodiment Construction

[0027] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0028] Such as figure 1 As shown, a kind of built-in comprehensive flushing negative pressure sealing drainage device that the present invention proposes, comprises porous foam body 7, medical sticking film, diversion connector 6, the external flushing pipe 5 with rubber cap, with pagoda type connector 2 External drainage tube1.

[0029] The lower surface of the porous foam body 7 is in contact with the wounded surface of the patient's skin, and the fluid guiding connector 6 is arranged above it. The drainage connection body 6 is provided with a drainage channel, a flushing channel and a catheter support 6-1. The front end of the external drainage tube 1 connected with the liquid collection bottle and the negative pressure device is fixed on the catheter support 6-1 through the pagoda joint 2, and communicates with the drainage chan...

Abstract

The invention discloses an embedded-type vacuum sealing drainage device for comprehensive washing. The embedded-type vacuum sealing drainage device comprises a lower surface and a porous foam body contacting with the wound skin surface of a patient. A flow guide connector is arranged on the upper side of the porous foam body, and is provided with a flow guide channel, a washing channel and a catheter support base. The front end, connected with a liquid collection bottle, of an external drainage pipe is fixed to the catheter support base through a pagoda-shaped joint, and is communicated with the drainage channel. An external washing pipe connected with an external washing liquid storage container is fixed to the catheter support base, and is communicated with the washing channel. A medicalfilm arranged on the upper side of the flow guide connector seals the flow guide connector, the porous foam body and the skin of the patient. The embedded-type vacuum sealing drainage device has theadvantages that exudates of a to-be-drained region is drained actively, continuously and efficiently through external negative pressure, the wound surface is enabled to be in a zero-gathering environment, and secondary absorption of organism toxin is reduced; sponge and the wound surface are washed comprehensively and continuously by washing liquid, and indentations are avoided without reduction of drainage effect when the wound surface is treated for a long time.

Description

technical field [0001] The invention relates to the field of medical devices, and is applied in various wound-protecting operations, in particular to a built-in comprehensive flushing negative pressure sealing drainage device without indentation and realizing continuous drainage. Background technique [0002] Vacuum sealing drainage (VSD for short) was invented by Dr. Fleischman of ULM University in Germany in 1992 and initially formed a theoretical prototype through clinical verification. It is used for wound drainage in surgical operations; in 1994, it was developed by Professor Qiu Huade in Guangzhou Introduced and applied the negative pressure sealing drainage technology in general surgery for the first time. Since then, the negative pressure sealing drainage technology has begun to be practically applied in general surgery in China. On March 18, 1998, Professor Wang Yanfeng and Professor Qiu Huade obtained the invention patent CN 2276350 authorized in China, and the neg...
