Problems solved by technology

Under normal circumstances, the breast duct syringe is modified from a 1ml syringe, that is, the needle of the 1ml syringe is ground into a blunt tip. When the end of the syringe enters the mammary duct, it still has friction damage to the inner wall of the mammary duct, which increases the pain of the patient; Or use a soft plastic tube for the needle, and open a hole in the side wall of the plastic tube. The soft plastic tube will bend when it enters the breast duct, so that the contrast fluid cannot flow out smoothly. In addition, when the contrast fluid flows out of the hole in the side wall, it often Overflow upwards, affecting the contrast effect

Embodiment Construction

[0009] Breast duct syringes, such as figure 1 , figure 2 and image 3 As shown, it includes a syringe 1 and a needle 2. The needle 2 is a hard hollow tube, and the hard structure facilitates the entry and exit of the mammary duct and facilitates the flow of contrast fluid. The lower end of the needle 2 is provided with an arc-shaped bottom surface 5, the bottom surface 5 protrudes outward, and the end of the needle is smooth, which will not cause damage to the breast duct of the patient and reduce the pain of the patient. A groove 4 is provided on the outer side and the bottom of the needle 2, and the contrast fluid flows downward along the groove 4 to avoid spillage and ensure the contrast effect. A pinhole 3 is provided in the middle of the groove 4, and the pinhole 3 communicates with the inner tube of the needle 2. The lower part of the groove 4 is a bar-shaped groove of equal width. This structure is convenient for the contrast fluid to flow downward; the width of the...

Abstract

A mammary gland catheter injector comprises a needle cylinder and a needle head. The needle head is in a hard hollow pipe shape. An arc bottom face is arranged at the lower end of the needle head. The bottom face protrudes outwards. Grooves are formed in the outer side and the bottom of the needle head. Needle holes are formed in the middle of the grooves. The needle holes are communicated with a needle head inner pipe. The end of the needle head is smooth and cannot damage a mammary gland catheter of a patient, the pain of the patient is lowered, a hard structure can go in and out of the mammary gland catheter conveniently, radiography liquid flowing is convenient, radiography liquid flows out along the grooves downwards, the phenomenon of overflowing is avoided, and radiography effect is guaranteed.

Description

technical field [0001] The invention relates to a medical device, specifically a breast duct syringe. Background technique [0002] Mammary duct radiography is an important method for diagnosing mammary duct disease. Contrast fluid is injected into the mammary duct through a mammary duct syringe to prepare for radiography. Under normal circumstances, the breast duct syringe is modified from a 1ml syringe, that is, the needle of the 1ml syringe is ground into a blunt tip. When the end of the syringe enters the mammary duct, it still has friction damage to the inner wall of the mammary duct, which increases the pain of the patient; Or use a soft plastic tube for the needle, and open a hole in the side wall of the plastic tube. The soft plastic tube will bend when it enters the breast duct, so that the contrast fluid cannot flow out smoothly. In addition, when the contrast fluid flows out of the hole in the side wall, it often Overflow upwards, affecting the contrast effect. ...
