Description

Technical Field

[0001] The utility model belongs to the field of medical technology, and in particular relates to a double-lumen catheterization and synchronous flushing device. Background Art

[0002] In medical practice, deep venous catheters (such as central venous catheters, hemodialysis catheters, etc.) are widely used in a variety of treatment scenarios such as intensive care, long-term infusion, and hemodialysis. In order to ensure the continued patency of the catheter and prevent thrombosis and infection, regular flushing of the deep venous catheter is a vital nursing measure. According to clinical practice and expert consensus, the frequency of deep venous catheter flushing is usually determined by the patient's specific condition and catheter type, but regular and frequent flushing is generally recommended. However, for double-lumen or multi-lumen deep venous catheters, traditional flushing methods often involve flushing each lumen one by one. This operation process is not only cumbersome and time-consuming, but may also increase the risk of catheter-related complications, such as catheter displacement, blood reflux, and cross-infection.

[0003] Based on this, it is extremely practical to provide a flushing device that can adjust the flow rate and can be quickly connected to other pipelines. Utility Model Content

[0004] The purpose of the utility model is to provide a dual-lumen catheterization and synchronous flushing device, aiming to solve the above technical problems.

[0005] The embodiment of the utility model provides a dual-lumen catheterization synchronous flushing device, which includes a first connecting tube, a flow regulating component and a quick connecting component.

[0008] The cam is connected to the second end of the fixing frame by a hinge connection, and the fixing frame is connected with the fixing frame by a hinge connection.

[0009] In one embodiment of the present invention, two fixed tubes are provided in the middle of a plurality of the limiting frames, one end of the two fixed tubes is movably connected to a drainage pipe, and one end of the two drainage pipes is sealed and connected to the second connecting pipe.

[0010] In one embodiment of the present invention, one end of the two fixed tubes is sealedly connected to a double-lumen tube, and one of the double-lumen tubes is sealedly connected to the other double-lumen tube.

[0011] In one embodiment of the present invention, the first connecting pipe and the second connecting pipe are both cast from metal chromium.

[0012] In one embodiment of the present invention, both the first delivery pipe and the second delivery pipe are cast from titanium alloy.

[0013] In one embodiment of the present invention, a sealing ring is provided at the connection between the fixed pipe and the drain pipe.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] 1) The provided pressure pump connecting pipe facilitates the user to connect the pressure pump connecting pipe to the pressure pump through an external pipe, so that the external pressure pump provides a stable pressure, and is connected to the external water source through the water inlet connecting pipe. At this time, the user allows external water to flow into the first connecting pipe through the water inlet connecting pipe. The user applies pressure to the first connecting pipe through the external pressure pump, and then the water flows through the high-precision flow regulating valve and the second delivery pipe into the second connecting pipe. The electromagnetic flowmeter will detect the flow and display it. If the flow does not meet the standard, the user can manually adjust the flow by adjusting the high-precision flow regulating valve, so that the flushing can be more stable during flushing, avoiding the problem of excessive or insufficient water flow causing harm to the patient, thereby achieving the purpose of stable flushing and flow regulation;

[0016] 2) The provided pressing plate facilitates the user to install the fixed pipe on the drain pipe by pressing the pressing plate so that the pressing plate transmits the downward force to the Z-frame. The Z-frame is subjected to the force and flips over through the hinge with the fixed frame. The flipping of the Z-frame will cause the damping rod spring to expand and store force. At this time, the user inserts the fixed pipe into the drain pipe, and then inserts the limit frame into the holder through the sliding guide rail. After insertion, the user releases the pressing plate, and then the force on the Z-frame disappears, causing the damping rod spring to reset and then the end of the Z-frame to be stuck in the slot in the limit frame, and then the fixed pipe is quickly connected. When it needs to be pulled out, the same operation is performed, thereby achieving the purpose of quick connection. BRIEF DESCRIPTION OF THE DRAWINGS
