Technical field

The utility model relates to the technical field of medical supplies, in particular to a medical drainage device.

Background technique

Clinically, after some patients undergo surgery, a drainage device will be used because there is blood and fluid accumulation inside the body cavity or deep within the surgical site that needs to be drained out. Drainage devices are mainly used in patients after surgery. In order to drain the fluid exuded from the wound surface out of the body, this requires the drainage device to have a certain continuous negative pressure. When caring for patients with a drainage ball (or drainage bag), it is necessary to regularly Pour the drainage fluid, record the nature and amount of the drainage fluid, and keep the drainage smooth.

The existing commonly used drainage device is shown in Figure 1, which generally includes a drainage ball 1-1 (or a drainage bag), and a drainage tube 1-2 and a drainage port 1 are provided on the drainage ball 1-1 (or the drainage bag). -3. The drain port 1-3 is provided with a valve body. When in use, insert the drainage tube 1-2 into the human body, operate the valve body to open the drain port 1-3, and manually squeeze out the drainage ball 1-1 (or After the gas in the drainage bag) is drained, the drain port is closed through the valve body, and the body fluid is sucked into the drainage ball 1-1 (or the drainage bag) through the pressure difference between the drainage ball 1-1 (or the drainage bag) and the body.

The drainage cavity in the existing drainage ball (or drainage bag) can be one, two or three. For example, the authorization announcement number is CN215230736U, the authorization announcement date is 2021.12.21, and the name is a disposable medical drainage A utility model patent for a precise liquid collection device, which includes a rectangular drainage bag made of transparent polyethylene material; a hollow cavity is provided in the drainage bag, and the hollow cavity includes a left cavity, a middle cavity, One right cavity. When the utility model is in use, the drainage fluid is guided by the drainage tube and falls into the middle cavity. When the middle cavity is full, the drainage fluid can overflow to the left and right cavities. The three chambers are all equipped with graduation marks to ensure that the drainage fluid flows from a small amount Accurate collection of many.

When using the existing medical drainage device, you need to insert the drainage tube into the body first, and then manually squeeze out the gas in the drainage ball (or drainage bag). This process can easily cause human discomfort, and when squeezing the drainage ball (or drainage bag) ), medical staff are required to quickly close the drainage port. If the drainage port is not closed in time, it will cause body fluids to leak out and cause infection. At the same time, when the body fluid in the drainage ball (or drainage bag) is stored to a certain amount, medical staff need to open it. The drainage port drains the fluid from the drainage ball (or drainage bag), which increases the risk of infection in the process.
