Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to an auxiliary guiding device for facilitating breast milk drainage with a blunt needle. Background Technology

[0002] Blunt needle lactation is a method of breast treatment using specially designed blunt needles. It is mainly used to resolve problems such as blocked or adhered mammary ducts, as well as to treat breast diseases such as mastitis. The principle behind blunt needle lactation is to utilize the flexibility and lack of sharpness of the blunt needle to deliver medication to the blocked area of ​​the mammary duct through the opening or existing channel. Because blunt needles are less likely to puncture surrounding tissue, pain and damage during treatment are reduced.

[0003] For blunt needle-based lactation unblocking, first, disinfect the nipple with povidone-iodine to ensure the treatment area is clean and sterile. Then, straighten the nipple and gently and slowly insert a blunt needle into the opening of the mammary duct. When the blunt needle reaches the blockage point of the mammary duct, deliver the medication to that location through a catheter connected to the blunt needle. The medication will then be evenly distributed to the surrounding tissue through the outlet on the side of the blunt needle.

[0004] Currently, there is a lack of guiding devices when using blunt needles to open milk ducts, making it difficult to insert the blunt needles properly into the mammary ducts. After insertion, the blunt needles must be held in the hand to prevent them from tipping over. When inserting the blunt needles, the nipples also need to be straightened with the fingers, making it difficult for the doctor to hold the nipples firmly, and they are prone to slipping out. Utility Model Content

[0016] 2. This utility model features a sliding lifting component on a support ring. By sliding the lifting component along the support ring, its position can be adjusted for ease of use. The extension and retraction of the vertical and horizontal plates of the lifting component can adjust the clamping forceps to a suitable position according to the nipple's location. The clamping plate of the clamping forceps holds the patient's nipple securely, and the silicone pad on the clamping plate provides a stable grip. By lifting the clamping forceps, the nipple is straightened, thus avoiding the problem of the nipple easily slipping out when pulled by hand. This facilitates straightening the nipple and makes subsequent blunt needle insertion easier. Attached Figure Description
