Description

Protective net cover for venous indwelling needle

Technical Field

The utility model relates to the field of medical supplies, especially, relate to a needle protection net cover is kept somewhere to vein.

Background

The venous indwelling needle is also called as venous trocar, the core component comprises a soft catheter/cannula which can be indwelling in the blood vessel and a stainless steel puncture guiding needle core, when in use, the catheter and the needle core are punctured into the blood vessel together, when the catheter completely enters the blood vessel, the needle core is withdrawn, and only the soft catheter is indwelling in the blood vessel so as to carry out transfusion treatment.

The use of the indwelling needle can reduce the pain of the patient caused by repeated venipuncture, facilitate clinical medication, rescue medication for critical patients and reduce the workload of nurses. After the puncture of the vein indwelling needle is successful, the indwelling needle needs to be fixed on the skin by a plaster to prevent falling off or moving, the existing hospital covers a layer of transparent plaster on the indwelling needle, for example, a ventilating type plaster for the vein indwelling needle with application publication number CN102441204A, has two surfaces of a smooth surface and an adhesive surface, and a plurality of circular air holes with the diameter of about 2-5 mm are punched on the periphery of the plaster. However, in the clinical nursing process, after the venous catheter is placed in a patient, the patient is easy to peel off due to the problems of the placed part and the skin of the patient, and medical workers need to use the adhesive tape for adhesion, so that the appearance is affected, and if the adhesive tape is less, the adhesive tape is easy to peel off, too much adhesive tape is easy to cause discomfort of the patient. For some patients with age and sensitive skin, the large area of the adhesive surface is stuck on the skin, the air permeability is poor, and skin allergy is easy to generate. And the adhesive of the adhesive on the common venous catheter patch is weakened due to the skin of a patient or sweating and the like, and the common venous catheter patch is easily stuck and cannot have a good fixing effect.
