Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of liver and gallbladder care, and in particular to a drainage device for liver and gallbladder care. Background Technology
[0002] A drainage device for hepatobiliary nursing is a medical device used after hepatobiliary surgery to drain excess fluid from the surgical site, thereby ensuring the surgical site remains dry, reducing the risk of infection, and promoting patient recovery.
[0003] Existing hepatobiliary drainage devices include a drainage bag, an upper drainage tube, a lower drainage tube, a three-way switching valve, a drain tube, a negative pressure connector tube, and a negative pressure needle tube. The upper drainage tube connects to the top of the drainage bag, one end of the lower drainage tube connects to the bottom of the drainage bag, and the other end connects to the three-way switching valve. The three-way switching valve is connected to both the drain tube and the negative pressure connector tube. The negative pressure needle tube is detachably connected to the negative pressure connector tube, thus providing both normal pressure and negative pressure drainage methods. However, because this type of hepatobiliary drainage device lacks internal support, the drainage bag deforms significantly when using the negative pressure method. Furthermore, the negative pressure adjustment of the negative pressure needle tube relies on the operator's experience, resulting in poor stability of negative pressure adjustment.
[0004] In the process of implementing this embodiment, the inventors discovered at least the following problems:
[0005] Existing liver and gallbladder care drainage devices, when using negative pressure, exhibit significant deformation of the drainage bag and poor stability in negative pressure adjustment. Utility Model Content
[0006] The purpose of this invention is to provide a drainage device for liver and gallbladder care, which solves the technical problems of large deformation of the drainage bag and poor stability of negative pressure adjustment in existing liver and gallbladder care drainage devices when using negative pressure.
[0007] Utility model solution:
[0008] This utility model provides a drainage device for hepatobiliary care, including a drainage bag, an upper drainage tube, a normal pressure tube, a negative pressure tube, a frame, and a negative pressure needle; the upper drainage tube is connected to the top of the drainage bag, the normal pressure tube is connected to the top of the drainage bag, the negative pressure tube is connected to the side of the drainage bag, and the frame is disposed inside the drainage bag; the negative pressure needle includes a needle tip, a needle tube, a piston, a tube cap, and a rotating component; the needle tip is detachably connected to the negative pressure tube, the needle tube is connected to the needle tip, the piston is slidably connected to the needle tube, the piston has an internally threaded tube, the rotating component has an externally threaded rod adapted to the internally threaded tube, the tube cap is threadedly connected to the needle tube and has a vent hole, and the rotating component is pivotally connected to the tube cap.
[0009] Furthermore, the drainage bag is provided with an emptying pipe at the bottom and with scale lines on its side.
[0010] Furthermore, the pipe cover is equipped with a bearing, and the rotating component is fixedly connected to the bearing.
[0011] Furthermore, a rubber sleeve is fixedly connected inside the negative pressure pipe.
[0012] Furthermore, the skeleton frame is provided with a reinforcing rib connecting two adjacent skeleton frames.
[0013] Furthermore, the piston component is provided with a piston groove.
[0014] Beneficial effects:
[0015] This invention provides a drainage device for hepatobiliary care. In negative pressure mode, a needle is inserted into the negative pressure tube, and the rotating component is turned. The external threaded rod of the rotating component moves the internal threaded tube upward, thereby causing the piston to stably regulate the negative pressure inside the drainage bag. The frame supports the drainage bag, preventing deformation. In normal pressure mode, the normal pressure tube is opened and the negative pressure tube is closed. This hepatobiliary care drainage device exhibits minimal deformation of the drainage bag and good stability in negative pressure regulation when using negative pressure mode.
