Description
Technical field
The utility model belongs to the field of medical instrument technology more particularly to disposable bubble filters closed safe vein
Remaining needle.
Background technology
Venous detaining needle is the new nursing technique to grow up in recent years in China, early in the 1960s,
Venous detaining needle just popularizes use as the substitute of scalp acupuncture by American-European countries, becomes the main tool of clinical transfusion.It
With vascular puncture number is reduced, intravenous extravasation is reduced, it is few to the stimulation of blood vessel, it is conducive to clinical application and urgent rescue, mitigates shield
The advantages that scholar's workload, raising nursing service quality and patient satisfaction.Now positive pressure needle-free connecting type is clinically mostly used to stay
Set two kinds of needle and security closed type remaining needle；Currently, the gas bubbles left that occurs when venous indwelling pin puncture and rushing during tube sealing
Air residue problem do not obtain effective solution but, to the infusion safety of patient, there are some potential safety problemss.
In conclusion problem of the existing technology is：Existing closed high-safety needle staying on vein can not effectively solve quiet
The gas bubbles left that occurs and air residue problem during tube sealing is rushed when vein punctures, existed to the infusion safety of patient
Some potential safety problems.
Invention content
In view of the problems of the existing technology, the utility model provides disposable bubble and filters closed safe vein
Remaining needle.
The utility model is realized in this way the closed high-safety needle staying on vein of disposable bubble filtering is provided with and stays
Needle stand is set, the front end sleeve of the indwelling needle is equipped with remaining needle casing, and the tail portion of the indwelling needle is set with Paracentesis needle holder, institute
The front end for stating Paracentesis needle holder is integrally equipped with puncture needle ontology；
The tail portion of the remaining needle casing is communicated with infusion tube, and the inside of the infusion tube is filled with filtering capsule, institute
It is intracapsular filled with multiple filtration film to state filtering.
Further, the external card of the infusion tube is equipped with tongs, and the end of the infusion tube is connected with three-way pipe,
It is set with Capsule on the three-way pipe.
Further, the filtering capsule uses transparent utricule structure.
Further, the Paracentesis needle holder surface is provided with anti-skid chequer.
The advantages of the utility model and good effect are：The disposable bubble filters closed high-safety needle staying on vein tool
Have it is easy to operate, damage it is small, mitigate patient pain.Capsule is filtered by setting and filter membrane can effectively carry out air bubble
Filtering, avoids air bubble from entering in human vas, has ensured the infusion safety of patient.
