Spliced type vacuum sealing drainage device and vacuum sealing drainage method

Abstract

The invention provides a spliced type vacuum sealing drainage device and a vacuum sealing drainage method. The spliced type vacuum sealing drainage device comprises a medical sponge, drainage tubes, washing tubes and inner connecting tubes, and a plurality of drainage holes are formed in the tube walls of the drainage tubes. The washing tubes comprise washing tube bodies and shower nozzles in a hindu lotus seedpod type, the shower nozzles are arranged at one ends of the washing tube bodies and are located in the medical sponge, and the washing tube bodies are located outside the medical sponge to be connected to a washing source. The drainage tubes extend in the medical sponge and are branched, and at least one drainage tube joint is formed on each side portion of the medical sponge. The inner connecting tubes are through tubes, the outer diameter of the inner connecting tubes is matched with the inner diameter of the drainage tube joints, and the inner connecting tubes can be inserted into the drainage tube joints in a fluid sealed mode. According to the prior art, the spliced type vacuum sealing drainage device has the advantages that the size of a needed single block is small, the device can be spliced, the exposed tubes are few, and the device can be provided with the independent washing tube.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a drainage tool and method for wounds, and more specifically to a spliced ​​negative pressure sealing drainage device and a negative pressure sealing drainage method. Background technique [0002] Negative pressure drainage is a technique of negative pressure suction using VSD material + semi-permeable membrane + three-way connection + negative pressure suction device. This technology was invented by the Germans in 1992 and introduced to China by Professor Juward in 1994. [0003] VSD (vaccum sealing drainage), also known as negative pressure sealing drainage technology, refers to the use of polyvinyl alcohol hydrated seaweed salt foam dressing (VSD accessories) containing drainage tubes to cover or fill wounds with skin and soft tissue defects, and then use The bio-semipermeable membrane seals it to make it a closed space, and finally connects the drainage tube to a negative press...

AI Technical Summary

Problems solved by technology

[0006] 1. The area of ​​a single block is too large and the cost is high. During the operation, half of the block is often used for the edge, and the rest is wasted

[0007] 2. The lavage and drainage of the edge part is not thorough and insufficient, often forming induration, causing the drainage tube to be blocked, resulting in poor drainage

[0008] 3. Excessive exposure of the drainage tube, too many joints, unsightly, easy to cause air leakage when the semi-permeable membrane is applied, resulting in negative pressure failure, resulting in a longer time for the membrane, prolonging the operation time, increasing the patient's medical expenses and surgical risks

During continuous negative pressure drainage and flushing after surgery, more tee tubes and flushing tubes are required, which greatly increases the nursing workload

[0009] 4. When using, the two VSDs need to be stitched manually, which is time-consuming and labor-intensive

[0010] 5. In the actual operation, it is necessary to debride the wound first and then cut the VSD according to the size of the wound, which is time-consuming and laborious
