Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to an anti-breakage fixing frame for a medical catheter. Background Art

[0002] During the treatment of patients, some need to leave various catheters in the body, such as indwelling needles, endotracheal tubes, gastric tubes, etc. In order to prevent these catheters from loosening, medical catheter fixing frames are generally used to fix these catheters on the patient.

[0003] The existing patent document with authorization announcement number CN219022891 U is fixed on external equipment, such as a bed, through a clamping base. Through multiple catheter clamping assemblies arranged on the top, it can be used to clamp and fix multiple catheters. At the same time, multiple catheter clamping assemblies are detachably installed, so that the number of catheter clamping assemblies on the entire fixing frame can be adjusted, and the disassembly and installation can be selected according to needs. The use effect is good, but when the above-mentioned medical catheter fixing frame is actually used, pressure is directly applied to the outer surface of the medical catheter for fixing, and there is hard contact between the medical catheter and the clamping assembly. When the medical catheter moves, it is easy for the medical catheter to break from the fixed position, affecting the normal use of the medical catheter. To this end, we provide a medical catheter anti-breakage fixing frame to solve the above problems. Utility Model Content

[0021] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0022] As described in the background technology, pressure is directly applied to the outer surface of the medical catheter to fix it. There is hard contact between the medical catheter and the clamping assembly. When the medical catheter moves, it is easy for the medical catheter to break at the fixed position, affecting the normal use of the medical catheter. For this reason, this embodiment provides an anti-breakage fixing frame for a medical catheter.

[0023] See also Figures 1 to 4 This embodiment proposes an anti-breakage fixing frame for a medical catheter, including a support plate 1, a sliding rod 5 is fixedly connected to the bottom surface of the support plate 1, a sleeve 6 is slidably connected to the outer surface of the sliding rod 5, a limiting rod 7 is slidably connected to the inner wall of the sleeve 6, and the limiting rod 7 is slidably connected to the sliding rod 5.

[0024] The outer surface of the slide bar 5 is provided with a plurality of reserved holes arranged at equal distances. The limit rod 7 can slide in the reserved holes on the slide bar 5 and the sleeve 6, and the slide bar 5 can slide up and down in the inner wall of the sleeve 6. By inserting the limit rod 7 into the reserved holes at different positions on the slide bar 5, the height of the support plate 1 can be adjusted, and then the height of the anti-breakage fixing frame for the medical catheter can be adjusted.

[0025] One end of the limiting rod 7 away from the sliding rod 5 is fixedly connected to a fixing block 8 , and a second spring 9 is sleeved on the outer surface of the limiting rod 7 , and both the limiting rod 7 and the fixing block 8 are fixedly connected to the second spring 9 .

[0026] Pulling the fixed block 8 can drive the limit rod 7 to slide in the reserved holes on the sliding rod 5 and the sleeve 6, and at the same time stretch the second spring 9 to make it produce elastic deformation, and release the fixed block 8. Under the resetting action of the second spring 9, the limit rod 7 can be driven by the fixed block 8 to return to the initial position.

[0027] Two symmetrical first reinforcing blocks 10 are fixedly connected to the bottom surface of the support plate 1. Both first reinforcing blocks 10 are fixedly connected to the slide rod 5. The first reinforcing blocks 10 can provide auxiliary support to the support plate 1 to play a reinforcing role, thereby improving the stability of the anti-breakage fixing frame for medical catheters during use.

[0028] An anti-breaking mechanism 2 is arranged on the outside of the support plate 1, and the anti-breaking mechanism 2 includes a plurality of first limit blocks 201, a fixed plate 202 and a second limit block 206. Each of the first limit blocks 201 and the fixed plate 202 are fixedly connected to the support plate 1, and the inner wall of each fixed plate 202 is threadedly connected with a first bolt 203, and the outer surface of each first bolt 203 is rotatably connected with a connecting block 204.

[0029] The support plate 1 supports the first limit block 201 and the fixed plate 202 . The inner wall of the fixed plate 202 is provided with an internal thread matched with the first bolt 203 . Rotating the first bolt 203 can drive the connecting block 204 to move closer to or away from the first limit block 201 .

[0030] The number of anti-breaking mechanisms 2 is determined according to actual production requirements, and labels are provided on the support plate 1 at positions corresponding to the medical catheter anti-breaking mechanisms 2, which can record the information of the medical catheter, making it easier for medical staff to find and observe the corresponding medical catheter.

[0031] The inner wall of each fixed plate 202 is slidably connected to two symmetrical guide rods 3, which are fixedly connected to the connecting block 204. The guide rods 3 can guide the movement of the connecting block 204 to improve the stability of the connecting block 204 during movement. One end of each guide rod 3 away from the connecting block 204 is fixedly connected to a limiting plate 4, which can limit the guide rod 3 to prevent the guide rod 3 from slipping out of the reserved hole on the fixed plate 202.

[0032] Two telescopic rods 205 are fixedly connected to a side of each connecting block 204 away from the first bolt 203, and the telescopic rods 205 are fixedly connected to the second limit block 206. The outer surface of each telescopic rod 205 is fixedly connected to a first spring 207, and the connecting block 204 and the second limit block 206 are fixedly connected to the first spring 207.

[0033] After the connecting block 204 moves, the second limiting block 206 is driven to move by the telescopic rod 205 and the first spring 207, so that the second limiting block 206 can be close to or away from the first limiting block 201. The first limiting block 201 and the second limiting block 206 are both provided with arc grooves, which can be easily fitted with the outer surface of the medical catheter.

[0034] The bottom end of the limiting rod 7 is fixedly connected to a C-shaped plate 11, the inner wall of the C-shaped plate 11 is threadedly connected to a second bolt 12, and the outer surface of the second bolt 12 is fixedly connected to a clamping plate 13. Rotating the second bolt 12 can drive the clamping plate 13 to move up and down, thereby fixing the C-shaped plate 11 to the bed, and the position can be adjusted as needed, thereby realizing the fixation of the medical catheter to the bed with an anti-breakage fixing frame, which is convenient for patients to use.

[0035] The upper surface of the clamping plate 13 is fixedly connected with an anti-skid pad 15 , which can increase the friction between the clamping plate 13 and the bed, thereby improving the stability of the medical catheter when the anti-breakage fixing frame is fixed to the bed.

[0036] A second reinforcing block 14 is fixedly connected to the upper surface of the C-shaped plate 11 , and the second reinforcing block 14 is fixedly connected to the limiting rod 7 . The second reinforcing block 14 can provide auxiliary support to the limiting rod 7 , play a reinforcing role, and thus improve the stability of the limiting rod 7 when in use.

[0037] The components in the drawings of the present invention are only for style reference and are not used as specific size standards. The specific sizes are determined according to the actual requirements of production.

[0038] Working principle: When using the anti-breakage fixing frame for medical catheters, first set the fixing frame at the position where it is needed, then place the medical catheter between the first limit block 201 and the second limit block 206, and then rotate the first bolt 203, the first bolt 203 drives the connecting block 204 to gradually approach the first limit block 201, the connecting block 204 drives the second limit block 206 to gradually approach the first limit block 201 through the telescopic rod 205 and the first spring 207, and the medical catheter is fixed between the first limit block 201 and the second limit block 206. The limiting block 206 is subjected to an external force to compress the telescopic rod 205 and the first spring 207, so that the telescopic rod 205 gradually contracts, and the first spring 207 produces elastic deformation. Under the resetting action of the first spring 207, the clamping force on the medical catheter is buffered, and a soft contact is formed between the second limiting block 206 and the medical catheter. Therefore, when the medical catheter moves, a slight slippage may occur at the contact point between the medical catheter and the second limiting block 206, thereby preventing the medical catheter from breaking from the fixed position, thereby ensuring the normal use of the medical catheter.
