Catheter fixer for medical nursing

Abstract

The utility model relates to the technical field of medical nursing, and discloses a medical nursing catheter fixator which comprises a first rectangular frame, a second rectangular frame, a lead screw, a rectangular sleeve, an arc-shaped pressing plate, a nut, a bevel gear and a bandage. In the using process, under the action of external force, any lead screw rotates, and then the bevel gear on the lead screw can be driven to rotate. Other bevel gears can rotate at the same time through the meshing effect between the teeth, and then the multiple lead screws rotate at the same time. And then, the four nuts can drive the four rectangular sleeves to move synchronously. And finally, the four arc-shaped pressing plates are driven to be close to or separated from one another, so that the guide pipe is clamped or loosened. When the guide pipe is fixed among the four arc-shaped pressing plates, due to the fact that the periphery of the guide pipe is evenly stressed, large deformation of the guide pipe in the radial direction can be avoided, and the flowing effect of liquid is guaranteed.

Description

Technical Field

[0001] The present application relates to the field of medical care technology, for example, to a catheter fixer for medical care. Background Art

[0002] Related art (publication number: CN220158999U) discloses a medical care catheter fixing device, including a mounting seat and a fixing assembly. The mounting seat includes a groove and a slot. The fixing assembly includes a cover plate, a connecting block, a plurality of limit blocks, and a clamping block. The cover plate is rotatably connected to the mounting seat and is located above the groove. The connecting block is fixedly connected to the cover plate and is located inside the slot. The plurality of limit blocks are fixedly connected to the connecting block and are sequentially located on one side of the connecting block. The clamping block can be mutually engaged with any limit block.

[0003] The related art (publication number: CN218607691U) discloses a catheter fixing device for medical care, which includes a flexible silicone plate, two mounting blocks are arranged at the top of the flexible silicone plate, a fixing frame is detachably mounted at the top of the two mounting blocks, and an adjustment component is arranged in the inner cavity of the fixing frame. A movable plate is arranged at the bottom of the adjustment component, and a fixing plate is arranged at the middle of the top of the flexible silicone plate, and the movable plate and the fixing plate clamp the catheter together.

[0004] In the process of implementing the above embodiments, it is found that there are at least the following problems in the related art:

[0005] In the process of fixing the catheter, the two medical care catheter fixing devices only apply a compressive force to one side of the catheter, and then clamp and fix the catheter under the action of the reaction force. However, most catheters are often made of soft materials, so under the combined action of the compressive force and the reaction force, the catheter is easily flattened, thereby affecting the normal flow of the liquid.

[0006] It should be noted that the information disclosed in the above background technology section is only used to enhance the understanding of the background of the present application, and therefore may include information that does not constitute the prior art known to ordinary technicians in the field.
