Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to a medical puncture device. Background Art

[0002] Medical puncture devices are an important medical tool designed for rapid and effective diagnosis and treatment in emergency situations. Such devices are typically used to perform procedures such as venipuncture, abdominal puncture, and thoracentesis in order to quickly obtain body fluid samples or drain effusions, helping doctors make timely medical decisions. In emergency settings, the rapid and accurate use of puncture devices can significantly improve rescue efficiency. In addition, the portability and ease of operation of puncture devices enable medical staff to respond quickly to patients' needs even in complex environments. Medical puncture devices are not only key tools to protect patients' lives, but also an important part of improving the quality of medical services. Through continuous technological innovation, future puncture devices are expected to take accuracy, safety, and patient comfort to a higher level.

[0003] After searching, the invention patent of Chinese patent number CN117442307A discloses an emergency internal medicine puncture device, including a fixed base, a curved slide rail group is provided at the top of the fixed base, a small air extraction and supply device is fixedly connected to the side of the bottom of the fixed base away from the curved slide rail group, a fixing mechanism is slidably connected to the middle of the curved slide rail group, the fixing mechanism includes a slide rod, an elastic limiting bag is provided above the slide rod, an air guide fixing ring is provided below the middle of the curved slide rail group, an elastic rubber adsorption box is evenly fixedly connected to the bottom end of the air guide fixing ring, and a rotating disk is provided above the air guide fixing ring. The present invention relates to the field of internal medicine puncture technology, and has the characteristics of strong practicability and the ability to reduce the occupation of medical staff by abdominal puncture. Compared with the prior art, the invention patent with Chinese patent number CN117442307A solves the problem that when abdominal puncture is needed to drain fluid from the patient in the emergency department, multiple medical staff are needed to perform abdominal puncture on the patient.
