For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0034] Refer to Figure 1 The present utility model provides a PICC catheter fixing device, including: a catheter placement bag 1, a dressing 8, a fixing ring 2, and a fixing frame 3. The catheter placement bag 1 is a pocket structure with an opening on one side for placing the end 6 of the PICC catheter.

[0035] The catheter placement bag 1 is a pocket structure with an opening on one side for placing the end 6 of the PICC catheter. The dressing 8 is used to fix the front end 7 of the PICC catheter at the puncture site of the patient. There are four fixing rings 2, two in a group. The two groups of fixing rings 2 are respectively arranged opposite to each other on one side of the dressing 8, and the fixing rings 2 in each group are spaced apart. The fixing frame 3 is a U-shaped frame. The end of the fixing frame 3 far from the opening is connected to one side of the opening end of the catheter placement bag 1. The two sides of the opening end of the fixing frame 3 can be respectively inserted into the fixing rings 2. When the fixing frame 3 is inserted into the fixing rings 2, the catheter placement bag 1 is used to fix the end 6 of the PICC catheter.

[0036] Specifically, the PICC catheter end 6 is placed in a catheter placement bag, and then both sides of the open end of the fixing frame 3 are respectively inserted into the fixing ring 2. Due to the gravity of the fixing frame 3, the catheter placement bag 1 and the PICC catheter end 6, the fixing frame 3 is fixed in the fixing ring 2. Through the application 8, the fixing ring 2 fixes the fixing frame 3 near the patient's puncture site, thereby fixing the PICC catheter end 6 in the catheter placement bag 1. Due to the fixation of the PICC catheter end 6, it is effectively prevented from being scratched when the patient puts on and takes off clothes. Since the catheter placement bag 1 is a pocket structure with one side open, placing the PICC catheter end 6 in the catheter placement bag 1 also reduces the probability of the PICC catheter end 6 being contaminated. Among them, the number of each fixing ring 2 can be set as needed, and the fixing ring 2 is made of plastic and has low cost.

[0037] In one embodiment, the fixing frame includes a first fixing rod 31, a second fixing rod 32 and a connecting rod 33. The two ends of the connecting rod 33 are respectively connected to one end of the first fixing rod 31 and one end of the second fixing rod 32, and the side of the connecting rod 33 is connected to one side of the opening end of the catheter placement bag 1. The connecting rod 33 is a metal wire. The first fixing rod 31 and the second fixing rod 32 can be inserted into the fixing ring 2 respectively.

[0038] The first fixing rod 31 and the second fixing rod 32 are both cylindrical. The function of the connecting rod 33 is to connect the first fixing rod 31, the second fixing rod 32 and the catheter placement bag 1. The metal wire used by the connecting rod 33 is preferably copper wire or iron wire. When the fixing frame 3 is inserted into the fixing ring 2, the dressing 8 fits the puncture site. The shape of the connecting rod 33 can be adjusted according to the different puncture sites, so that the connecting rod 33 also fits the skin, thereby making the fixing frame 3 more stable and not affecting the patient's activities.

[0039] Furthermore, the PICC catheter fixing device further comprises a limiting plate 4, which is respectively arranged on the first fixing rod 31 and the second fixing rod 32. The limiting plate 4 is used to limit the fixing frame 3 when the fixing frame 3 is inserted into the fixing ring 2.

[0040] Among them, the limit plate 4 is respectively arranged on the first fixing rod 31 and the second fixing rod 32, and is close to one end of the connecting rod 33. When the fixing frame 3 is inserted into the fixing ring 2, the limit plate 4 abuts against the upper edge of the uppermost fixing ring 2, limiting the fixing frame 3 from passing through the fixing ring and continuing to move downward.

[0041] Furthermore, free ends of the first fixing rod 31 and the second fixing rod 32 are respectively provided with limiting members, which are used to prevent the fixing frame 3 from falling out of the fixing ring when the fixing frame 3 is inserted into the fixing ring 3 .

[0042] When the fixing frame 3 is inserted into the fixing ring 2 , the limiting member prevents the fixing frame 3 from falling out of the fixing ring 2 during the patient's activities.

[0043] Further, the stopper is a clamping ring 5. The cross-sectional diameter of the clamping ring 5 is larger than that of the fixing ring 2. The clamping ring 5 is a deformable annular structure with a notch, made of plastic, and detachably fixed to the free ends of the first fixing rod 31 and the second fixing rod 32. When the fixing frame is inserted into the fixing ring, the clamping ring abuts against the lower edge of the fixing ring.

[0044] Furthermore, the first fixing rod 31 and the second fixing rod 32 are made of plastic, which is low in cost.

[0045] In one embodiment, the stopper is a nut. The free ends of the first fixing rod 31 and the second fixing rod 32 are respectively provided with threads corresponding to the nut. The nut can be screwed onto the free ends of the first fixing rod 31 and the second fixing rod 32.

[0046] Specifically, when the fixing frame 3 is inserted into the fixing ring 2, the nut is screwed onto the free ends of the first fixing rod 31 and the second fixing rod 32 to prevent the fixing frame 3 from coming out of the fixing ring 2 during the patient's activities. Preferably, the first fixing rod 31, the second fixing rod 32 and the nut are all made of plastic material, which is low in cost and light in weight.

[0047] In one embodiment, the first fixing rod 31 and the second fixing rod 32 are made of rubber, and a metal wire is provided in the middle. The metal wire is preferably a copper wire or an iron wire. When the fixing frame 3 is inserted into the fixing ring 2, the free ends of the first fixing rod 31 and the second fixing rod 32 are respectively rotated by a certain angle so that the free ends of the first fixing rod 31 and the second fixing rod 32 abut against the fixing ring 2, thereby preventing the fixing frame 3 from falling out of the fixing ring 2 during the patient's activities.

[0048] In one embodiment, the catheter placement bag 1 is made of medical gauze. Medical gauze can reduce the probability of contamination of the PICC catheter end 6 and provide a relatively sterile retention environment. It should be noted that the catheter placement bag 1 can be made of the same material as the dressing 8 for easy processing.

[0049] Example

[0050] After the medical staff performs the intravenous PICC catheter indwelling operation, first, the needle of the front end 7 of the PICC catheter is fixed at the puncture site with the dressing 8, and then the end 6 of the PICC catheter is placed in the catheter placement bag, and then the clamping ring 5 is removed from the fixing frame 3, and the fixing frame 3 is inserted into the fixing ring 2, and the limiting plate 4 abuts against the upper edge of the fixing ring 2 near the connecting rod 33. Finally, the clamping ring 5 is installed on the free ends of the first fixing rod 31 and the second fixing rod 32 respectively, abutting against the lower edge of the fixing ring 2, and then the shape of the connecting rod 33 is adjusted to make the shape of the connecting rod 33 fit the skin of the puncture site, and the fixing of the end 6 of the PICC catheter is completed. Through the action force between the limiting plate 4 and the clamping ring 5, the end 6 of the PICC catheter can be better fixed on the fixing frame 3. It plays a fixing role to prevent the patient from scratching when putting on and taking off clothes. The setting of the catheter placement bag 1 also reduces the probability of the PICC catheter end being contaminated.
