Description

Technical Field

[0001] The utility model relates to the technical field of medical auxiliary equipment, in particular to a positioning device for an infusion port. Background Art

[0002] An infusion port is a closed venous infusion system that is completely implanted in the body. It can provide patients with long-term venous blood vessel access and is suitable for cancer patients who need long-term chemotherapy, repeated blood draws, blood transfusions, and long-term intravenous nutrition. Compared with common deep vein puncture catheters, the infection rate of the infusion port is very low and it can provide a long-term and reliable central venous access. However, the infusion port is buried under the skin, and it is not easy for people with insufficient nursing experience to find the center of the infusion port.

[0003] According to the description of an auxiliary positioning device for an infusion port disclosed on the patent website (the authorization announcement is CN 212880423U), "An auxiliary positioning device for an infusion port includes a C-shaped ring, a through hole perpendicular to the axis of the C-shaped ring is provided on one side wall of the C-shaped ring, a straight rod passing through the through hole is provided in the through hole, a first clamping part is connected to one end of the straight rod located inside the C-shaped ring, a hand-held part is provided at the other end of the straight rod, a second clamping part is fixedly installed on the inner wall of the C-shaped ring facing the first clamping part, elastic ropes are provided at both ends of the first clamping part and the second clamping part, and the other ends of the two elastic ropes are fixedly connected through a positioning ring."

[0004] In view of the above description, the applicant believes that there are the following problems:

[0005] During use of the utility model, the utility model drives the straight rod to move inward by pressing the handheld part, so that the first clamping part and the second clamping part can clamp the infusion port base, and the positioning ring can be positioned to the center of the infusion port base under the drive of the elastic rope. However, during actual use, the device drives the straight rod by pressing the handheld part, so that the first clamping part and the second clamping part clamp the infusion port, and the staff is required to press the handheld part by hand to determine the position of the infusion port, which makes it difficult for subsequent staff to perform other operations because they have only one hand, and the device is not provided with a handle mechanism, which is not convenient for staff to take. Therefore, it is necessary to improve a positioning device for an infusion port. Utility Model Content
