Description

Technical Field

[0001] The utility model relates to the field of medical devices, and particularly relates to a PICC catheter fixing assembly. Background Technique

[0002] The full name of PICC catheterization is peripherally inserted central catheterization. A catheter is used to puncture any one of the peripheral arm veins, such as the basilic vein, median cubital vein or cephalic vein in the cubital fossa, and the catheter reaches the large veins close to the heart, such as the superior vena cava or inferior vena cava, which can avoid direct contact between the drug and the arm vein, thereby reducing the irritation of the drug to the blood vessel.

[0003] As described in a PICC pipeline fixing device (authorization announcement number: CN 215841105U) disclosed by the national patent network, "The utility model discloses a disposable PICC catheter fixing assembly, including a patch. A catheter clamping clip is arranged on the top surface of the patch. A film is arranged on the top surface of the patch. The film includes a film layer and a bottom film layer. A hole slightly larger than the patch is arranged on the bottom film layer. The bottom surface of the film layer corresponding to the outside of the hole is provided with film adhesive. The film layer is provided with a fixed connecting line connected to the top surface of the patch at the hole of the bottom film layer. A plurality of pre-tearing lines extending to the hole are arranged on the bottom film layer. In the utility model, there is a non-adhesive area at the patch of the film. When the film is torn, the patch will not be lifted, and because there is a fixed connecting line between the film and the patch, the non-adhesive area can be accurately aligned."

[0004] Although this device is convenient to use by setting a non-adhesive area, in the actual fixation of PICC catheters, long-term use of patches is likely to cause medical adhesive-related skin damage and reduce the comfort of patients. Therefore, we need to set up a PICC catheter fixing assembly to solve this problem. Content of the Utility Model

[0005] Aiming at the deficiencies of the prior art, the utility model provides a PICC catheter fixing assembly. The device provides additional support and fixation for the catheter by setting a fixing mechanism, reducing the direct adhesion of the fixed catheter to the skin, thereby reducing the risk of skin damage.

[0006] A PICC catheter fixing assembly includes a mounting frame. A moving groove is arranged inside the mounting frame. One end of the mounting frame is fixedly connected with a fixed shaft. The surface of the fixed shaft far away from the mounting frame is fixedly connected with a connecting rod. A fixing mechanism and a mounting mechanism are sequentially arranged on the surface of the mounting frame.

[0007] The above technical solution further includes:

[0008] The fixing mechanism includes an adjusting component and a locking component. The adjusting component includes a threaded rod fixedly connected inside the moving groove. A moving block is sleeved on the surface of the threaded rod. The locking component includes a fixing plate. A soft pad is fixedly connected to the bottom of the fixing plate. A magic tape is fixedly connected to the surface of one end of the fixing plate close to the fixed shaft. A fixed bottom plate is fixedly connected to the surface of the other end of the fixing plate away from the mounting mechanism. A pressing plate is arranged above the fixed bottom plate. A plug board is inserted into one end of the fixed bottom plate away from the fixing plate. The magic tape can fix the end of the PICC catheter. By setting the soft pad, the compression feeling of the catheter on the local tissue is reduced, and the pain of the patient is reduced. At the same time, it is set to be detachable, which is easy to clean and disinfect, helps to keep the puncture site clean and dry, and reduces the infection risk.

[0009] An opening is arranged at one end of the fixed bottom plate away from the fixing plate. A placing groove is formed on the top surface of the fixed bottom plate. Two positioning grooves are also formed on the surface of the fixed bottom plate and are symmetrically distributed with respect to the placing groove. A positioning bolt is fixedly connected to the bottom surface of the pressing plate. The size and position of the positioning bolt correspond to the size and position of the positioning groove. Ribs are arranged inside the placing groove, which can provide an additional fixing and locking effect when the pressing plate fixes the PICC.

[0010] Two slots are formed on the surface of one end of the fixing plate close to the fixed bottom plate and are symmetrically distributed on the surface of the fixing plate. The plug board is in a "C" shape and the positions of the two arms correspond to the positions of the slots. A fixed abutting block is fixedly connected to the middle position of the plug board. An opening is arranged at one end of the fixed abutting block close to the fixing plate. The size of the fixed abutting block is slightly smaller than the size of the opening of the fixed bottom plate. The position of the fixed abutting block corresponds to the position of the fixed bottom plate.

[0011] A connecting plate is fixedly connected to the surface of the end of the moving block away from the moving groove. A telescopic rod is fixedly connected to the bottom of the connecting plate. The bottom of the telescopic rod is fixedly connected to the fixing plate.

[0012] Two groups of the threaded rod and the connecting plate are symmetrically distributed with respect to the fixing plate. Two groups of four telescopic rods are evenly distributed at the four corners of the fixing plate.

[0013] The mounting mechanism includes arc plates. Two arc plates are fixedly connected to the surface of the fixed shaft. The arc plates are semi-circular and the openings face the central position. A through groove is formed at the inner central position of the arc plates and internal threads are formed on the inner surface. A threaded column is inserted into the through groove. The thread of the threaded column corresponds to the internal thread. A nut is fixedly connected to the surface of one end of the threaded column close to the outside of the arc plate. A locking plate is rotatably connected to the surface of one end of the threaded column close to the inside of the arc plate.

[0014] One end surface of the locking plate away from the arc plate is fixedly connected with a convex block, and a plurality of the convex blocks are arranged and evenly distributed on the surface of the locking plate.

[0015] One end surface of the locking plate close to the arc plate is fixedly connected with a compression spring. The end of the compression spring away from the locking plate is fixedly connected to one end surface of the arc plate close to the locking plate. A plurality of the compression springs are arranged and symmetrically distributed about the threaded column. The compression springs are in a compressed state. By adjusting the position of the locking plate driven by the threaded column, the locking plate is fixed on the patient's arm. The provided compression springs can provide additional stability.

[0016] Advantageous effects:

[0017] 1. The device is provided with a fixing mechanism. The device fixes the catheter by arranging an additional mounting plate. On the one hand, it can more effectively prevent the catheter from shifting inside or outside the patient's body. This fixing method is more stable than traditional patch and tape fixing, reducing the risk of catheter slippage or displacement caused by patient movement or external forces. By providing a non-skin support point for the catheter, the entire fixing system becomes more stable and reliable. On the other hand, by arranging a soft pad at the bottom of the mounting plate, it reduces skin discomfort and damage caused by long-term pressure and improves patient comfort.

[0018] 2. The device is provided with a mounting mechanism. The device provides a fixing force for the device by arranging a detachable fixing arc plate. On the one hand, it is convenient for medical staff to carry out maintenance and replacement, without the need to frequently replace the adhesive patch, reducing the nursing workload. At the same time, when the patient feels uncomfortable or needs to adjust the catheter position, it can also be operated more easily. On the other hand, it reduces the discomfort such as skin itching and pain caused by long-term use of the adhesive patch and improves patient comfort. Description of the drawings

By adjusting the position of the threaded post 33 to drive the locking plate 35, the locking plate 35 is fixed on the patient's arm. The arranged compression springs 37 can provide additional stability.

[0042] Working principle: During actual use, before using this device to fix the exposed part of the PICC catheter, the device needs to be bound first. Specifically, first rotate the nut 34 so that the threaded column 33 in front of it moves in the arc plate 31. When the threaded column 33 moves in the arc plate 31, it will drive the locking plate 35 set at the top of the threaded column 33 to stretch outwards, widening the central part. Then, sleeve the locking plate 35 on the appropriate part of the patient's arm. Next, rotate the nut 34, and the nut 34 will drive the threaded column 33 and the locking plate 35 in front to press against the arm, completing the portable fixation of the device on the arm. At the same time, since the compression spring 37 between the arc plate 31 and the locking plate 35 is in a compressed state, the two ends of the locking plate 35 can fit better. Thus, the binding and installation of the device are completed.

[0043] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention.
