Technical Field

The invention relates to the technical field of medical instruments, in particular to an ileum cleaning device for replacing the recovery period of bladder operation by ileum.

Background

The ileum bladder replacing operation is to modify part of ileum to replace bladder when the bladder of patient is affected. In the postoperative recovery period, urine and partial intestinal fluid in the new bladder with the modified ileum need to be led out of the body, so that the low pressure of the new bladder is kept, and the healing of an anastomotic stoma is promoted. At present, one end of the fistulation tube is inserted into a new bladder, so that the liquid in the new bladder flows into the drainage bag. However, the ileum secretes more mucus than other intestinal tracts, and especially mucus begins to increase within two to three days after operation and reaches a peak in about one week. As a replacement for the bladder, the mucus secreted therefrom can easily cause the stoma to become blocked with mucus and thus poor drainage can occur, which can cause the stoma to leak urine and slow healing.

An ileal irrigation device for use in ileal replacement of the recovery phase of bladder surgery according to any one of claims 6-8, characterized in that the pressure increasing and reducing device also comprises a pressure control assembly, the pressure control assembly comprises a first pressure sensor, a second pressure sensor, a fourth electromagnetic valve, a fifth electromagnetic valve and a controller, the first pressure sensor is arranged on the buffer tank (11), the second pressure sensor is arranged on the end part of the fistulization tube, the fourth electromagnetic valve and the fifth electromagnetic valve are respectively arranged on the air inlet pipe (14) and the air suction pipe (15), the controller is respectively connected with the first pressure sensor, the second pressure sensor, the fourth electromagnetic valve, the fifth electromagnetic valve and the telescopic mechanism (13), two groups of preset pressure values are respectively set for the first pressure sensor and the second pressure sensor by the controller, and the two groups of preset pressure values comprise a high pressure value and a low pressure value;

when the infusion bag (1) is inflated, the fourth electromagnetic valve and the fifth electromagnetic valve are both in a locking state, the telescopic mechanism (13) is started, when the first pressure sensor detects that the pressure value in the buffer tank (11) reaches the high pressure value of the first pressure sensor, the fourth electromagnetic valve is opened, and the controller controls the telescopic mechanism (13) to be started or closed, so that the pressure value in the buffer tank (11) is maintained at the high pressure value of the first pressure sensor; when the second pressure sensor detects that the pressure value in the ileum reaches the high pressure value of the second pressure sensor, the fourth electromagnetic valve is locked, and the telescopic mechanism (13) stops working;

when air is sucked into the liquid collecting cavity (4), the fourth electromagnetic valve and the fifth electromagnetic valve are both in a locking state, the telescopic mechanism (13) is started, when the first pressure sensor detects that the pressure value in the buffer tank (11) reaches the low pressure value of the first pressure sensor, the fifth electromagnetic valve is opened, and the controller controls the telescopic mechanism (13) to be started or closed, so that the pressure value in the buffer tank (11) is maintained at the low pressure value of the first pressure sensor; when the second pressure sensor detects that the pressure value in the ileum reaches the low pressure value of the second pressure sensor, the fifth electromagnetic valve is locked, and the telescopic mechanism (13) stops working.
