Description

Technical Field

[0001] The utility model relates to the technical field of catheter fixing devices, in particular to a catheter fixing device for hepatobiliary and pancreatic surgical nursing. Background Art

[0002] Hepatobiliary surgery mainly studies major diseases that seriously threaten the health of Chinese people, such as hepatocellular carcinoma, hepatobiliary stones, post-hepatitis cirrhosis and acute liver failure caused by severe hepatitis. Nursing is an applied science, which is divided into home care and paid care. Patients in hepatobiliary and pancreatic surgery often need to insert medical catheters such as drainage tubes for treatment. After the tube is inserted, the doctor or nurse fixes the catheter with medical tape. When the patient moves, the tape is very likely to break, resulting in unplanned extubation. The existing method is to stick the adhesive sheet on the patient and then fix the catheter with Velcro, but the catheter fixation effect of this method is still insufficient. When the patient moves and turns over, unplanned extubation may still occur. For this reason, we propose a catheter fixing device for hepatobiliary and pancreatic surgery nursing.

[0004] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a catheter fixing device for hepatobiliary and pancreatic surgical care, comprising a fitting sheet and a mounting block, two groups of extrusion blocks are arranged in a mirror image on the upper side of the mounting block, a connecting block is fixedly connected between the extrusion block and the connecting block, a movable groove is opened on the upper side of the mounting block, a movable block is movably installed inside the movable groove and the movable block is fixedly connected to the side position of the extrusion block, a catheter is arranged between the two groups of extrusion blocks, a fixed block is fixedly installed on the side of the two groups of extrusion blocks, mounting rods are equidistantly fixedly connected to the side of the fixed block and the mounting rods penetrate the fixed block, and a nut block is threadedly sleeved on the side of the mounting rod.

[0005] Preferably, the extrusion block is an arc-shaped block made of rubber.

[0006] Preferably, the movable groove is a convex groove, and the movable block is a convex block.

[0007] Preferably, deformation blocks are fixedly installed equidistantly between the two groups of extrusion blocks, and the deformation blocks are hollow arc-shaped blocks made of rubber material.

[0008] Preferably, a reinforcing block is fixedly installed inside the deformation block, and the reinforcing block is a circular ring block made of elastic plastic material.

[0009] Preferably, restraint rods penetrating the movable block are fixedly installed equidistantly inside the movable groove, and the restraint rods are round rods.

[0010] Beneficial Effects

[0011] The utility model provides a catheter fixing device for hepatobiliary and pancreatic surgical nursing. It has the following beneficial effects:

[0012] (1) When the catheter fixing device for hepatobiliary and pancreatic surgical care is used, the movable block slides inside the movable groove to drive the two groups of extrusion blocks to adjust their positions. The two groups of extrusion blocks squeeze and fix the catheter and at the same time, the nut block is moved and fixed on the side thread of the mounting rod. This plays a fixing role for catheters of different specifications, strengthens the fixing effect of the catheter, and avoids the occurrence of unplanned extubation.

[0013] (2) When the catheter fixing device for hepatobiliary and pancreatic surgical care is in use, the deformable block further supports and fixes the catheter, the reinforcing block strengthens the support of the deformable block and enhances the fixation of the catheter, and the restraining rod restrains and guides the movable block, thereby improving the practicability of the device.
