Second, left atrial pressure cannot be monitored, and is a key indicator before and after withdrawal of the cardiac extracorporeal circulation. Third, the left heart drainage position needs to be adjusted many times, which delays the operation time.
The utility model has the following contents:
an object of the utility model is to provide a cardiac operation left heart drainage tube improvement device to solve the not enough of prior art.
The utility model discloses by following technical scheme implement: the utility model provides a cardiac surgery left heart drainage tube improvement device, including the drainage tube, a plurality of drainage hole has been seted up to the end of drainage tube, it has a plurality of arc support's both ends to paste through the super glue on the drainage tube, drainage channel has been seted up to the inside of drainage tube, the one end of transmission line is run through the lateral wall of drainage tube and the end department that drainage channel is located the end department of drainage tube and transmission line and is connected with the pressure measurement sensor, the other end of transmission line is connected with signal converter, the other end of drainage tube has the vacuum aspiration ware through the connecting pipe through connection, the one end outside-in of tubule runs through the drainage tube lateral wall and stretches out the lateral wall and the end department through.
Preferably, the arc-shaped support is a member made of medical silica gel materials, and the hollow bag is a plastic bag.
Preferably, the other end of the thin tube is connected with a syringe in a penetrating way.
The utility model has the advantages that: this cardiac surgery left heart drainage tube improvement device, the both ends that have a plurality of arc support through the powerful adhesive subsides on the drainage tube, support cardiac internal tissue through the arc support, make certain wind direction appear in cardiac internal tissue and drainage hole, thereby avoid holding too many tissues, lead to the drainage tube end to block up and unable work, the end of drainage tube is connected with pressure cell, monitor left room pressure through pressure cell, before shutting down to cardiac surgery in-process and extracorporeal circulation, left room pressure after has audio-visual observation, inject gas to hollow bag through the syringe, be convenient for carry out the internal fixation through hollow bag to the drainage tube end.
