Abstract

The invention discloses an anti-slipping adjustable puncture needle fixer, which relates to the technical field of puncture needle fixers and comprises a sleeving assembly, wherein the sleeving assembly comprises an elastic binding belt, one side of the elastic binding belt is fixedly provided with a connecting frame, and one side of the connecting frame is provided with an infusion part. The invention effectively solves the defects of poor stability of the puncture needle fixer and insufficient moving requirement of an adaptive patient through the cooperative design of the sleeving component and the limiting component, on one hand, abandons the fixation of a single proximal needle end, adds the limiting clamping seat of the adjustable distal needle end, forms the double-point constraint of 'the fitting fixation of the proximal needle end and the traction buffering of the distal needle end', disperses the pulling force generated when the patient stands up and turns over, resists the external force impact caused by the great movement of limbs, and radically avoids the displacement of the fixer and the falling off of the puncture needle, and on the other hand, adopts the design of the medical flexible silica gel pad and the elastic bandage, reduces the local fixing pressure and improves the comfort level of the puncture part of the patient.

Description

Anti-slip adjustable puncture needle fixer Technical Field The invention relates to the technical field of puncture needle holders, in particular to an anti-slip adjustable puncture needle holder and a use method thereof. Background In clinical intravenous fluid puncture, arterial blood gas analysis puncture, central venous catheterization and other diagnosis and treatment scenes, an anti-slip adjustable puncture needle fixer is often required to be used for accurately controlling fixation firmness, size suitability, skin compatibility and operation convenience, so that the condition that the puncture needle is shifted out to cause liquid medicine extravasation and bleeding due to limb movement of a patient, or the puncture needle with different specifications cannot be adapted due to unadjustable fixation size, allergy is caused by skin material stimulus contact, or the fixation operation is complicated and the emergency treatment opportunity is delayed is avoided, and therefore the diagnosis and treatment safety, the comfort level of the puncture part and the clinical operation efficiency of the patient are influenced. The existing puncture needle fixer has obvious defects in fixing stability and adapting to the activity requirement of a patient, the limiting mode is single, the near needle end of the puncture needle is only used for attaching and fixing, an auxiliary limiting structure of the far needle end is lacking, when the patient is lifted up, turned over and the like and is greatly moved and operated, the fixer is easily driven to shift due to limb traction, the infusion needle is tilted, the problem of falling off of the puncture needle is caused, the single near needle end fixing design cannot disperse the pulling force generated when the patient moves, the fixing acting force is concentrated in a local part, the external force impact caused by the great activity of the limb is difficult to resist, the discomfort of the puncture part of the patient is possibly caused due to the overlarge local pressure, meanwhile, the puncture needle falls off to interrupt infusion treatment, diagnosis and treatment progress is not only influenced, but also medical liquid is possibly wasted, if the patient is required to be re-punctured, pain of the patient and the workload of medical staff are further increased, and even extra medical risks are possibly caused by bleeding and infection of the puncture part.
