18 results about "Thoracentesis" patented technology

Thoracentesis /ˌθɔːrəsɪnˈtiːsɪs/, also known as thoracocentesis (from the Greek θώραξ thōrax "chest, thorax"—GEN thōrakos—and κέντησις kentēsis "pricking, puncture") or pleural tap (from the Greek πλευρά pleura or πλευρόν pleuron "side, rib"), is an invasive procedure to remove fluid or air from the pleural space for diagnostic or therapeutic purposes. A cannula, or hollow needle, is carefully introduced into the thorax, generally after administration of local anesthesia. The procedure was first performed by Morrill Wyman in 1850 and then described by Henry Ingersoll Bowditch in 1852.

A skin tensioning device suitable for use in a thoracentesis

The application discloses a skin tension device suitable for thoracentesis, and relates to the technical field of thoracentesis. The tension device comprises a base, a moving stretching component, a thoracentesis limiting component, an angle adjusting device and a supporting device. When working, a patient sits on the base, the height of the base can be adjusted according to the height of the patient, and the supporting device can provide suitable back support for the patient. After the patient sits down, medical staff drives the angle adjusting device to adjust the whole thoracentesis tension device to a suitable angle of the thoracic cavity area to be punctured of the patient, then the moving stretching component generates a moderate tension on the skin, and the skin at the puncture site is taut, thereby creating good conditions for subsequent puncture operation. Meanwhile, the thoracentesis limiting component can preliminarily guide and limit the direction and depth of the puncture needle. The skin is taut through the moving stretching component, and the application has the effect of meeting different puncture requirements.

Post-thoracentesis continuous compression hemostasis fixing device

PendingCN121910436ASurgeryThoracentesisThoracic cavity
The invention discloses a post-thoracentesis continuous compression hemostasis fixing device, and relates to the technical field of surgical thoracentesis. The post-thoracentesis continuous compression hemostasis fixing device comprises a wearing fixing bandage, a puncture position compression attaching pad and a magnetic attraction connecting base, and the magnetic attraction connecting base is connected to the outer wall of one side of the wearing fixing bandage in an adhesive mode. By means of the linkage design of the pressure self-adaption part and the respiratory rhythm, dynamic self-adaption adjustment of the compression force can be achieved, when a patient inhales and the thorax is expanded, the buffer force storage spring capable of storing the force under pressure can automatically reset, the generated elastic force can push the magnetic linkage pressing plate to apply stable compression force to the puncture position compression attaching pad attached to the puncture point, and therefore the puncture position can be pressed. The traction effect of thoracic expansion on the compression pad is counteracted, and hemostasis pressure attenuation is avoided.

An integrated thoracentesis assembly

PendingCN122123758ASurgical needlesTrocarPleural cavityDilator
This invention relates to the field of medical device technology and discloses an integrated thoracentesis assembly, including a drainage tube and a display. A puncture needle is disposed within the drainage tube, and the front end of the puncture needle has a puncture needle expansion section. The expansion section includes a self-puncture tip, a tapered expansion segment, and a main body segment. The puncture needle enters the pleural cavity through the expansion section, eliminating the need for guidewire insertion and dilation, eliminating the window period, preventing air from entering the pleural cavity, and reducing the risk of repeated punctures and infection. This invention achieves one-step puncture and catheter placement by overlapping the puncture needle and drainage tube, inserting them simultaneously during puncture, removing the inner core after successful insertion, and leaving the outer tube in place. This eliminates the need for guidewire insertion and dilation, significantly simplifying the operation. The drainage tube is equipped with a valve-type one-way valve to maintain a seal during puncture, solving the problem of tissue debris blockage in the absence of a needle core.
