[0003] Based on the above, the applicant has found that the existing intraoperative body fluid extraction and collection device has the following deficiencies:

[0004] 1. The piston rod is a push-pull type, which can easily cause the piston rod to fall back due to negative pressure when extracting body fluids;

[0005] 2. The collection bottle is hung on the operating table through a frame, which is easy to be displaced due to misoperation during the operation. It is inconvenient to install fixing measures on the collection bottle to fix the collection bottle on the guardrail on the operating table. Utility Model Content

[0029] The specific usage and function of this embodiment are as follows:

[0030] In the utility model, Figure 1 The device body 1 is shown in a state where it is fixed on the guardrail of the operating table. Figure 2The guardrail interception part is between the fixed bearing tube 7 and the guardrail locking button 9 shown in the figure, thereby realizing the fixation of the device body 1. When the device body 1 is in use, the extraction pipe is installed on the pipe docking tube of the extraction collection bottle 6, and the other end of the extraction pipe is aligned with the body fluid to be extracted. Insert the finger into the semicircular head of the lifting and rotating plate 4. You only need to insert any end, and then rotate the lifting and rotating plate 4 with your fingers, and drive the lifting piston rod 3 to rotate synchronously through the lifting and rotating plate 4, so that the lifting piston rod 3 rotates and engages with the lifting bearing cover 2 threadedly, so that the lifting piston rod 3 rises through the threaded engagement, and the lifting piston plate 5 is driven to rise synchronously by the lifting piston rod 3, so that negative pressure is generated inside the extraction collection bottle 6 at the bottom of the lifting piston plate 5, and the body fluid can be extracted using the extraction pipe through the negative pressure.

[0031] Embodiment 2:

[0032] The difference from the first embodiment is that the regular hexagonal groove of the fixed stop column 8 can also be set as a regular heptagonal groove, so that the fixed stop column 8 can only be rotated by a special tool that cooperates with the regular heptagonal groove, preventing non-staff from rotating and disassembling the fixed stop column 8.

[0033] Embodiment three:

[0034] The difference from the first embodiment is that the right end surface of the fixed stop column 8 can also be set to a frosted surface, thereby increasing the friction between the right end surface of the fixed stop column 8 and the extraction collection bottle 6, preventing the fixed stop column 8 from rotating loose.
