Drawings
Fig. 1 is a schematic view of the overall structure in the embodiment of the present invention.
In the figure: 1. a sleeve; 11. a card slot; 2. a needle core; 21. a first card body; 3. a cell brush head; 4. a sealing tube; 5. a cell brush body; 6. a second card body; 7. a clamping body; 8. a graduated scale; 9. a cell brush handle.
Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
Example (b): a cell brush for pleura brush detection is shown in figure 1 and comprises a sleeve 1 and a needle core 2 inserted into the sleeve 1. During the process of inserting the sleeve 1 into the pleural cavity, the needle core 2 is inserted into the sleeve 1. The cell brush also comprises a sealing tube 4 and a cell brush body 5 inserted into the sealing tube 4, wherein the sealing tube 4 is connected with the sleeve 1 in a sealing way. One end of the cell brush body 5 is provided with a cell brush head 3, and the other end is provided with a cell brush handle 9. The end part of the sealing tube 4 close to the cell brush handle 9 is fixedly connected with a clamping body 7, and the cell brush body 5 is inserted with the clamping body 7.
After the sleeve 1 has entered the pleural cavity, the needle core 2 is removed from the sleeve 1. The sealing tube 4 is inserted into the sleeve 1, so that the sealing tube 4 is connected with the sleeve 1 in a sealing way. The cell brush handle 9 and the clamping body 7 are held, the distance between the cell brush handle 9 and the clamping body 7 is shortened, and the cell brush body 5 sends the cell brush head 3 into the pleural cavity from the sealing tube 4. The sleeve 1 is rotated, and the pleura brushing detection is carried out after the cell brush head 3 is contacted with the pleura. After the pleura brush is examined and is examined the completion, lengthen the distance between cell brush holder 9 and the clamping body 7, the cell brush body 5 is in taking out sealed tube 4 with cell brush head 3, then wash after taking out sealed tube 4 and sleeve 1 in proper order. Utilize sealed tube 4 and sleeve 1 sealing connection, prevent that the outside air from getting into the pleural cavity, examine the condition appearance that the in-process reduced artifical pneumothorax at the pleura brush. The cell brush handle 9 and the clamping body 7 are utilized to ensure that the cell brush is simple to send out and withdraw.
