Abstract

The invention discloses a blood recovery device based on thrombus filtration. When the invention recovers blood, since a suction shield is provided, the position of the blood can be protected through the suction shield, preventing the suction head from directly The problem of blood outflow facing the wound can prevent misoperation, etc. At the same time, the controller of the present invention can automatically adjust and control the suction force of the negative pressure suction component according to the amount of blood detected by the blood detection probe, In this way, the pressure of negative pressure suction can be adjusted in real time to ensure blood recovery while preventing adverse effects on the wound; the present invention is also provided with a pressure stabilizing bag, and the setting of the pressure stabilizing bag is faster than directly using a suction negative pressure pump. Direct control is more stable and prevents adverse effects such as fluctuations in the suction pump.

Description

technical field [0001] The invention relates to a blood recovery device based on thrombus filtration. Background technique [0002] During the operation of installing the thrombus filter, the surgical incision will bleed a lot, so it is necessary to recycle the blood. The existing recycling method uses a syringe for suction or a negative pressure suction method. For the syringe suction method, it is generally sucked first and then The disadvantages of this way of pressing the blood sucked into the syringe into the collection cup are: when the blood volume is large, it needs to be sucked and discharged multiple times, and it is not convenient to recover the blood. However, the existing common negative pressure suction method is subject to the suction force of the negative pressure. In this way, if the position is improper or the operation is slightly careless when suctioning, it is easy to cause blood to flow out due to the suction force of the negative pressure. Especially ...
