Drainage device

Abstract

The invention discloses a drainage device. The drainage device comprises a drainage assembly and a negative-pressure assembly. The drainage assembly comprises a drainage tube, more than one drainage port, a hard catheter and a fixing ball. The drainage tube is communicated with the drainage ports. The hard catheter penetrates through the drainage ports to be connected with the drainage tube. The fixing ball is detachably connected to the opening of the hard catheter. An exhaust tube is arranged on the lower surface of the drainage tube and communicated to the drainage tube in a bent mode. The negative-pressure assembly comprises a negative-pressure tube, a negative-pressure connector and an air bag, wherein the negative-pressure tube is connected to the lower surface of the drainage tube and communicated with the drainage tube. When the drainage device is applied to drainage, operation is easy and convenient, multi-layer drainage can be achieved, blockage will not be caused easily, and the drainage speed and the drainage pressure can be monitored; meanwhile, the inside of a drainage bag can be kept in a negative-pressure state all the time, so that the drainage operation can be smoothly carried out, a solid foundation is laid for draining materials in the body thoroughly, and the work intensity of medical workers is reduced to a certain degree.

Description

technical field [0001] The invention relates to a medical device, in particular to a drainage device. Background technique [0002] In the clinical treatment of many diseases in neurosurgery, such as the treatment of severe intracranial injury and hypertensive hemorrhage, neurosurgery drainage devices are required. When performing neurosurgery on patients, due to the rich intracranial blood vessels, multi-level separation is required, and there will be more bleeding, which requires drainage of the oozing blood and other waste fluid after the operation, and multi-level Drainage. If multiple drainage hoses are concentrated near the wound, it will be more complicated to handle, and at the same time, it will easily cause the drainage to leak out, increasing the chance of wound infection. In addition, during drainage, the drainage tube connects the needle tube and the negative pressure ball again, which is not only inconvenient to operate, but also time-consuming and laborious....

Problems solved by technology

If multiple drainage hoses are concentrated near the wound, it will be more complicated to handle, and at the same time, it will easily cause the drainage to leak out, increasing the chance of wound infection

In addition, during drainage, the drainage tube connects the needle tube and the negative pressure ball, which is not only inconvenient to operate, but also time-consuming and laborious. The drainage tube needs to be connected repeatedly, which increases the work intensity of the medical staff.
