Description

Technical Field

[0001] The utility model relates to the technical field of catheter fixation, and particularly relates to a catheter fixation device. Background Art

[0002] Hematology is an independent branch of medical science that mainly studies blood and hematopoietic tissues. Clinical hematology focuses on the causes, pathogenesis, clinical manifestations, and treatment measures of various blood diseases (such as leukemia, aplastic anemia, hemophilia, deep vein thrombosis, etc.). When hematologists perform blood sampling and blood transfusion, they need to fix the catheter.

[0003] During the use of existing catheters, they are generally fixed on the patient's limb using medical tape. This fixation method has two defects. One is that the air permeability of the medical tape is poor. When pasted on the skin for a long time, it is easy to cause local skin ulceration, reducing the comfort of the patient. At the same time, as the use time of the medical tape increases, affected by sweat and other external factors, the edges will curl up, and it is easy to fall off over time, which may cause the catheter to fall off, and there are certain potential safety hazards in use. Content of the Utility Model

[0004] In order to overcome the above-mentioned defects of the prior art, an embodiment of the utility model provides a catheter fixation device to solve the problems raised in the above background art.

Detailed Description of the Invention

[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0021] As Figures 1-4 , a catheter fixing device includes an installation frame 1. Two sets of movable blocks 2 are movably arranged inside the installation frame 1. Installation plates 3 are fixedly arranged on the lower sides of the two sets of movable blocks 2. The installation plates 3 movably penetrate through the installation frame 1 and extend to the lower side. And a clamping block 4 is fixedly arranged on the outer side of the installation plate 3 at the lower side part of the installation frame 1. Two sets of positioning springs 5 are arranged inside the installation frame 1. One ends of the two sets of positioning springs 5 are respectively connected to both sides of the installation frame 1, and the other ends of the positioning springs 5 are connected to the movable blocks 2. An arc-shaped block 6 is fixedly arranged on the outer side of the movable block 2. A movable plate 7 for docking with the arc-shaped block 6 is movably arranged inside the installation frame 1. A threaded rod 13 is fixedly arranged on the upper side of the movable block 2. The threaded rod 13 movably penetrates through the installation frame 1 and extends to the upper side. And a wing nut 14 is threadedly sleeved on the outer side of the threaded rod 13 at the upper side part of the installation frame 1. A chute 15 for docking with the threaded rod 13 is penetrated and opened on the upper side of the installation frame 1. The positioning spring 5 is initially in a stretched state. Through the elasticity of the positioning spring 5, the clamping block 4 can be driven to quickly clamp on the outer side of the limb, so as to facilitate the fixation of the whole device and improve the use convenience.

[0022] Among them, a connecting rod 8 is fixedly arranged on the outer side of the movable plate 7. The connecting rod 8 movably penetrates through the installation frame 1 and extends to the outside. And a movable disk 9 is fixedly arranged on the outer side part of the connecting rod 8 at the outer side of the installation frame 1. Anti-slip lines are arranged on the outer side of the movable disk 9. By pressing the movable disk 9, the movable plate 7 can be driven to extrude the arc-shaped block 6, so as to conveniently drive the clamping block 4 to move and improve the loading and unloading convenience of the device.

[0023] Among them, a square rod 10 is fixedly arranged inside the installation frame 1. The square rod 10 movably penetrates through the movable block 2. By arranging the square rod 10, the movable block 2 can be limited, and the moving stability of the movable block 2 can be improved, so as to ensure the moving stability of the clamping block 4.

[0024] Among them, a limiting block 11 for docking with the movable plate 7 is fixedly arranged on the outer side of the arc-shaped block 6. The limiting block 11 can limit the movable plate 7, so that the movable plate 7 can continuously extrude the arc-shaped block 6 to ensure the normal use of the device.

[0025] Among them, a breathable pad 12 is fixedly arranged on the outer side of the clamping block 4. The breathable pad 12 is made of a soft material. By arranging the breathable pad 12, the comfort of the patient can be improved, and at the same time, the use stability of the device is further improved.

[0026] Among them, a rubber block 16 is fixedly arranged on the upper side of the mounting frame 1. A plurality of groups of positioning holes 17 are formed in the upper side of the rubber block 16. And a patch 18 is movably arranged on the upper side of the mounting frame 1. The upper side of the soft rubber block 16 is provided with positioning holes 17 of multiple sizes, which can fix catheters of different sizes. At the same time, in cooperation with the patch 18, the catheter can be firmly fixed on the upper side of the mounting frame 1, ensuring the stability of the catheter during use and being convenient for operation.

[0027] Among them, a return spring 19 is sleeved outside the connecting rod 8. One end of the return spring 19 is connected to the movable plate 7, and the other end of the return spring 19 is connected to the inner side of the mounting frame 1. The return spring 19 is initially in a contracted state. When the movable disk 9 is released, the elasticity of the return spring 19 can drive the movable plate 7 to quickly separate from the arc-shaped block 6, so that the clamping block 4 can quickly clamp the limb for fixation.

[0028] Embodiment: During the use of the present utility model, first, pressing the movable disk 9 drives the connecting rod 8 and the movable plate 7 to move. When the movable plate 7 moves, it stretches the return spring 19 and simultaneously squeezes the two arc-shaped blocks 6 on the inner side of the mounting frame 1. The arc-shaped block 6 is squeezed to drive the movable block 2 to slide on the outside of the square rod 10 and compress the positioning spring 5. When the movable block 2 slides, it drives the mounting plate 3 and the clamping block 4 to move. Then, the mounting frame 1 is attached to the outside of the patient's limb. Then, the movable disk 9 is released. At this time, the return spring 19 resets and contracts, driving the movable plate 7 to move and separate from the arc-shaped block 6. At this time, the positioning spring 5 rebounds and drives the clamping block 4 to move and clamp on the outside of the limb, so that the mounting frame 1 can be quickly fixed. Then, the two wing nuts 14 are tightened downward, so as to position and fix the mounting frame 1 and ensure the stability of the mounting frame 1. Then, the catheter can be inserted into the corresponding positioning hole 17 on the rubber block 16, and at the same time, the patch 18 can be used to paste the catheter to ensure the stability of the catheter during use.
