Description

Technical Field

[0001] The utility model relates to the field of medical instruments, in particular to a disposable extension tube with an anti-falling structure. Background Art

[0002] During surgery, disposable extension tubes are often used to inject multiple drugs for patients. Existing disposable extension tubes usually use a three-way structure to connect the hose for the injection of multiple liquid medicines. However, the three-way structure has the risk of being twisted in the wrong direction, and the pipeline is long and prone to entanglement. Among them, a disposable extension tube with application number "CN202223227683.3" replaces the three-way valve structure with three soft catheters, and a one-way valve is connected to one end of the soft catheter to avoid blood and fluid reflux; and it can be removed as a whole at the end of the operation to avoid errors and save costs, and solves the problem that the three-way valve is easily twisted in the wrong direction. However, the extension tube still has certain shortcomings when used: for deep vein catheterization, especially for patients with internal jugular deep vein catheterization, when using a disposable extension tube, a speed controller needs to be installed on the long tube body. Since the upper part of the tube body has a fixed structure, the speed controller's own gravity causes traction on the tube body, causing the internal jugular catheter to be easily detached, and then the patient's comfort is reduced. Utility Model Content

[0003] The utility model aims to provide a disposable extension tube with an anti-falling structure to solve the problem in the background art that the bag body has no fixed structure and is prone to fall down when there is too much drainage fluid inside the bag body, causing pulling on the stoma and causing discomfort to the patient.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a disposable extension tube with an anti-falling structure, comprising a tube body, a fixing mechanism and a positive pressure heparin cap;

[0005] Wherein: one end of the tube body is fixedly connected to an infusion device interface, an infusion needle is connected inside the infusion device interface, and a speed controller is installed on the surface of the tube body;

[0006] The fixing mechanism comprises a support block arranged on one side of the pipe body, a pipe clamp is fixedly connected to the surface of the support block, the pipe body is clamped inside the pipe clamp, a connecting belt is fixedly connected to the back of the support block, and a fixing clip is connected to one end of the connecting belt;

[0007] The positive pressure heparin cap is fixedly connected to the other end of the tube body.

[0008] As a preferred solution of the utility model: a strap is fixedly connected to one side of the support block, a Velcro block is connected to the surface of the strap, and a Velcro block is connected to the other side of the support block. The strap passes around the tube body and is bonded to the Velcro block through the Velcro block.

[0009] As a preferred solution of the utility model: the fixing clamp includes an L-shaped fixing seat connected to one end of the connecting belt, a sliding groove is opened on the inner side of the L-shaped fixing seat, a clamping plate is slidably connected inside the sliding groove, a screw is threadedly connected to the top of the L-shaped fixing seat, one end of the screw is inserted into the sliding groove and is rotatably connected to the surface of the clamping plate.

[0010] As a preferred solution of the utility model: the surfaces of the L-shaped fixing seat and the clamping plate are both connected with silicone blocks.

[0011] As a preferred solution of the utility model: a single-hand clamp is slidably connected to the surface of the tube body.

[0012] As a preferred solution of the utility model: a three-way interface is installed on the surface of the pipe body.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] (1) When the patient is receiving an intravenous injection, the tube body is clamped inside the tube clamp on the surface of the support block, and the strap on one side of the support block is pulled around the tube body so that the strap is attached to the other side of the support block by magic to prevent the support block from sliding. The connecting strap on the back of the support block is pulled up so that the fixing clip at one end of the connecting strap is clamped on the surface of the clothes. The weight of the speed controller on the surface of the tube body is transferred to the clothes through the connecting strap, thereby preventing the speed controller from being pulled on the built-in tube by gravity, thereby improving the patient's comfort.

[0015] (2) The fixing clamp is composed of an L-shaped fixing seat, the inner side of which is provided with a sliding groove, and the clamping plate is slid in the sliding groove. The internal thread of the sliding groove is connected to a screw rod, and one end of the screw rod is rotatably connected to the clamping plate. When the screw rod rotates, it moves up and down in the L-shaped fixing seat, thereby driving the clamping plate to slide in the sliding groove, so that the distance between the clamping plate and the L-shaped fixing seat changes, which is convenient for clamping on clothes of different thicknesses. The silicone blocks on the surface of the clamping plate and the L-shaped fixing seat can increase the clamping friction and prevent the clamping plate and the L-shaped fixing seat from sliding when clamped on the clothes.
