Mouthful, the patient's body surface is tangible after healing is taken out stitches protrudes ball to one.When treatment from this positioning knit stitch, by needle percutaneous puncture vertically into
Enter to the reservoir for puncturing seat, both can easily be injected, can also long-time continuous transfusion and blood sampling, and be suitable for
The chemotherapeutics of high concentration, the infusion of total parenteral nutrition, blood product.Because catheter tip is in big vein, Neng Gouxun
Speed dilution drug concentration, avoids the stimulation to vascular wall and damage, than the chance that general venous transfusion reduces vascular sclerosis, also subtracts
Lack because can not find the hardship that blood vessel is had an acupuncture treatment repeatedly.
When Clinical practice, the thumb, index finger and middle finger that generally require nurse's proficiency surround triangle, from three direction hands
It holds transfusion port to be fixed, the syringe of another hand-held powder charge is inserted perpendicularly into from transfusion port midpoint and wears across three fingers
Thorn is every the bottom for the reservoir that goes directly., can be movable in a certain range since the puncture seat of transfusion port is embedded in subcutaneously, it adds
The reasons such as disinfection and perspiration cause moist skin to be easy sliding, are easy to fix hand in accidentally thorn, or be pierced into out of plumb when puncturing seat
And liquid is caused to discharge unsmooth and patient pain.
CN204951843U discloses a kind of implanted transfusion port puncture locator, including one piece of slide, this slide
Shape it is identical as the injection seat top surface shape of implanted transfusion port, this slide size is more slightly larger than the size of injection seat top surface,
There are one hole, the shapes and sizes phases of the shapes and sizes in this hole and the puncture diaphragm on injection seat top surface at the center of slide
Together.When carrying out implanted transfusion port puncture procedure, operator pinches puncture locator edge with left-hand finger, while relying on finger
Touch find the subcutaneous injection seat of patient, confirm the edge of injection seat top surface, make puncture locator outer and injection seat top surface
Outer coincide, the hole at puncture locator center is aligned with the puncture diaphragm on implanted transfusion port, and specifying can be with
The position of inserting needle.Not damaged needle is pierced into out of puncture locator center hole, so that it may complete puncture procedure.Utilize this implantation
Formula transfusion port puncture locator carries out implanted transfusion port puncture procedure, and positioning is easy to accurate.CN204521800U discloses one
Kind Novel vein transfusion port puncture fixator, including retainer body；The retainer body is the cylinder of inner hollow,
The top of retainer body is closed by top plate, and the bottom end of retainer body is open end, at the top center of retainer body
It is provided with puncture hole, the lateral surface of retainer body is equipped with to crack with what the puncture hole communicated.
