Description

Technical Field

[0001] The utility model relates to the technical field of fixators, in particular to a special fixator for PICC catheters. Background Art

[0002] A PICC catheter refers to a peripherally inserted central catheter. Its principle is to puncture through the veins in the peripheral arm with a catheter, and the catheter reaches the large veins close to the heart. This can avoid the direct contact between chemotherapy drugs and arm veins. Coupled with the very fast blood flow speed in the large veins, it can quickly dilute chemotherapy drugs and prevent drug irritation to blood vessels. PICC catheters are soft in texture and can be retained for a long time, from 1 to 2 years. They are mostly used for tumor patients who need long-term chemotherapy, patients with long-term parenteral nutrition, and patients with long-term infusion. According to the publication number: CN214232390U, a special fixator for PICC catheters is disclosed, including a fitting plate and a PICC tube. An S-shaped embedding groove is opened at the upper end of the fitting plate, a protection groove connected to the other end of the S-shaped embedding groove is opened at the upper end of the fitting plate, several fixing components matching the catheter are arranged at the upper end of the fitting plate, a covering cloth is arranged at one end of the fitting plate, a second magic male buckle is arranged at the covering end of the covering cloth and the fitting plate, a second magic female buckle matching the second magic male buckle is arranged at the upper end of the fitting plate, several rubber rings are evenly arranged at the lower end of the fitting plate, a fixing strap is arranged at the front end of the fitting plate, a third magic male buckle is arranged at the other end of the fixing strap, and a third magic female buckle matching the third magic male buckle is arranged on the fixing strap. The utility model can effectively fix and protect the PICC tube, avoid its falling off or being contaminated by external influences, and can be conveniently and quickly fixed to the patient's arm for easy use. However, the above technology still has some defects. For example, the existing fixator only fixes the PICC catheter through a wire clamping block. During long-term use, when the user's arm bends, the ICC catheter will fall off, and the practicability is poor and needs to be improved. Summary of the Utility Model

A spring band 18 is fixedly installed on the left side of the mounting plate 1. A mounting block 19 is fixedly installed on the left side of the spring band 18. A hook 20 is fixedly installed on the left side of the mounting block 19, which can better improve the wearing comfort. During use, first place the mounting plate 1 in the required position. At this time, the protective pad 15 will be stuck between the arm and the mounting plate 1. Then pinch the hook 20 to align with the snap ring 17. When the hook 20 is stuck on the snap ring 17, it is okay. And at this time, the snap ring 17 rotates on the right side of the mounting plate 1 through the side block 16 to adapt to the angle of the hook 20, so as to prevent the situation that the mounting plate 1 is uncomfortable to wear during use. The snap ring 17 is rotatably connected to the mounting plate 1, the spring band 18 is slidably connected to the mounting plate 1, and the hook 20 is slidably connected to the snap ring 17, which is more convenient for the snap ring 17 to rotate and avoid the situation that the snap ring 17 is stuck by the mounting plate 1 during use and the snap ring 17 cannot rotate continuously.

[0027] Working principle: During use, first place the mounting plate 1 in the required position. At this time, the protective pad 15 can be stuck between the mounting plate 1 and the user's arm. Then pinch the hook 20 to bypass the user's arm and align with the snap ring 17. At this time, the hook 20 drives the spring band 18 to slide through the mounting block 19. When the hook 20 is stuck on the snap ring 17, it is okay. And at this time, the snap ring 17 rotates on the right side of the mounting plate 1 through the side block 16 to adapt to the angle of the hook 20. Then place the PICC catheter into the inside of the fixing block 2 through the groove 3. At this time, pinch the side plate 12 and pull it to the right, so that the clamping plate 10 rotates to the right at the top of the fixing block 2 through the hinge 9. When the bottom end of the clamping plate 10 touches the top of the fixing block 2, and the clamping block 11 slides into the inside of the fixing block 2 through the groove 3 and fixes the PICC catheter firmly, it is okay. And at this time, the side plate 12 drives the cushion 13 to slide down at the top of the fixing block 2. When the cushion 13 slides into the inside of the card slot 4, it is okay. Then pinch the block 8 to align the clamping rod 6 with the fixing slot B14 and push it inward, so that the clamping rod 6 passes through the side plate 12 through the fixing slot B14 and slides into the inside of the fixing block 2 through the fixing slot A5. When the clamping rod 6 completely slides into the inside of the fixing block 2 through the fixing slot A5, it is okay. At this time, the soft pad 7 can firmly clamp the clamping rod 6 inside the fixing block 2, and the clamping rod 6 and the side plate 12 firmly clamp the clamping plate 10 at the top of the fixing block 2 through the fixing slot B14.
