The present invention discloses a constant temperature salt water enema device. The constant temperature salt water enema device comprises a liquid storage bag, a squeeze bag and an enema tube, the liquid storage bag communicates with the squeeze bag through a main guiding tube, the squeeze bag communicates with the enema tube through a connection tube, the main guiding tube is provided with a first control valve, the connection tube is provided with a second control valve, the enema tube is provided with a lower branch tube and an upper branch tube, the upper branch tube communicates with theconnection tube, and the lower branch tube is provided with a fourth control valve. When the constant temperature salt water enema device is used, the first control valve is firstly opened, so that the liquid storage bag and the squeeze bag are in a communication state, then the squeeze bag is squeezed, so that the air in the squeeze bag enters into the liquid storage bag along the main guiding tube, thus liquid in the liquid storage bag enters the squeeze bag, so that the squeeze bag is filled with salt water, at this time, the first control valve is closed, the second control valve is opened, then the squeeze bag is squeezed again, so that the constant temperature salt water enters the enema tube through the connection tube and the enema can be realized.
