| description | The utility model relates to the technical field of medical instruments, in particular to a pressure pump for perfusion in lung bronchus, which comprises a pressure conveying device and a perfusion device, the pressure conveying device is connected with the perfusion device through a hose, the perfusion device comprises a perfusion tube, one end of the perfusion tube is provided with a conical catheter, and the other end of the perfusion tube is provided with a drainage tube. A reversing valve is arranged at the other end of the infusion tube, the reversing valve is connected with the pressure conveying device through a hose and used for adjusting the flow direction and pressure of the infusion liquid, and a pressure gauge is arranged at the position, close to the reversing valve, of the infusion tube. Compared with the prior art, the infusion device has the advantages that the infusion pressure is constant due to the fact that the reversing valve is arranged, the pressure of infusion liquid can be adjusted a |
