Pediatric kidney puncture needle

Abstract

The invention discloses a pediatric kidney puncture needle. The pediatric kidney puncture needle comprises a puncture needle body, a transparent blind tube, a first transparent tube, a sterilizing tube and a second transparent tube, wherein the first transparent tube, the sterilizing tube and the second transparent tube are in threaded connection sequentially. The transparent blind tube is provided with scale lines uniformly, a conical needle seat is arranged at the back end of the transparent blind tube and is connected with a blood storage chamber through a threaded connecting tube, the blood storage chamber and the first transparent tube are formed integrally, a blood discharge opening is formed in one end of the blood storage chamber, a first liquid storage chamber is connected to the upper end of the sterilizing tube in a threaded mode, a round disk is fixedly mounted in the second transparent tube, a cross-shaped open slot is formed in the center of the round disk, a handle is connected at the tail end of the puncture needle body in a threaded mode, the inner wall of the transparent blind tube is provided with a plurality of sealing chambers uniformly, each sealing chamber is filled with water, and a filter screen is arranged closely to a front-end needle tip. When using the pediatric kidney puncture needle, a doctor can observe surrounding tissues clearly and control puncture depth accurately. The pediatric kidney puncture needle is convenient to use and high in puncturing success rate.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to a pediatric kidney puncture needle. Background technique [0002] Kidney puncture needles are often used in the detection of kidney disease. Usually, doctors perform blind puncture through years of experience. With the development of ultrasound technology, the use of ultrasound equipment for detection can greatly improve the accuracy of puncture. However, due to the small size of children, It is easy to insert too little or too much, which causes pain to the patient and is not conducive to medical diagnosis. At the same time, the boundaries of surrounding tissues are not clear during puncture, which affects the doctor's diagnosis and adds great difficulty to the medical staff. Contents of the invention [0003] In order to solve the above problems, the present invention provides a pediatric kidney puncture needle, which can clearly observe the surrounding tissue, accurately c...
