Thoracentesis guiding and positioning device for respiratory department

Abstract

The invention discloses a thoracentesis guiding and positioning device for a respiratory department. The device comprises a fixing seat, a screw is installed in the middle part of the lower end of thefixing seat, and a clamping plate is arranged at the upper end of the screw. A supporting frame is installed in the middle part of the upper end of the fixing seat, and the top end of the supportingframe is provided with a cross frame. A drive shaft is installed in the middle of the cross frame, a rotating cam is mounted in the middle of the drive shaft, the lower end of the rotating cam is contacted with a lifting rod, a lifting plate is mounted at the bottom end of the lifting rod, and a fixing column is mounted in the middle of the lower end of the lifting plate. A pin is installed in themiddle of the fixing column, and a strap is installed on the outer side of the lower end of the fixing column. A guide disc is arranged in the middle of the lower end of the strap, and a drain tube is installed in the middle of the right end of the fixing column. The device achieves the function of guiding and positioning the pin, so that the pin can be accurately inserted into the thoracic cavity, a series of side effects caused by manual insertion of the pin by medical staff is avoided, and the operation difficulty of the medical operation is greatly reduced. At the same time, the device issimple to operate, high in reliability and capable of meeting the requirement for thoracentesis.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a thoracentesis guiding and positioning device for respiratory department. Background technique [0002] Respiration refers to the process of gas exchange between the body and the external environment. The human respiration process includes three interrelated links: external respiration, including lung ventilation and lung ventilation; gas transport in the blood; internal respiration, which refers to the gas exchange between tissue cells and blood. During the breathing process, the chest cavity is the most important part. The chest cavity is a cavity surrounded by the sternum, thoracic vertebrae and ribs. The upper part is connected to the neck, and the lower part is separated from the abdominal cavity by the diaphragm. The heart, lungs and other organs are all in the chest cavity. .

AI Technical Summary

Problems solved by technology

[0003] In the process of existing diagnosis and treatment of thoracentesis, because the puncture device needs to be inserted by hand, it is difficult to fix the device. When the patient fine-tunes the posture or coughs slightly due to pain and discomfort or the influence of the disease, it will seriously affect the normal puncture, which not only affects the puncture device. In addition, it is easy to free the needle body during drainage or pumping, and even the position is out of alignment, piercing into the chest organs, causing organic damage, and increasing the difficulty of the operation for medical staff.
