In practical medical operations such as retention enema, when the speed regulating device 4 is used, the height of the enema bag 34 is generally adjusted according to the specific situation and treatment requirement of the patient, the liquid flow rate is controlled within a proper range, generally varies from tens milliliters to hundreds milliliters per minute, for example, for some patients with relatively sensitive intestinal tracts, the flow rate may be controlled within 30-50 milliliters per minute, for patients with relatively good intestinal tract tolerance, the flow rate may be properly increased to about 100-200 milliliters per minute, etc., and the number of the speed regulating devices 4 and the vertical liquid flow rate of the enema bag 34 are in the range of 30-50 milliliters per minute when the height of the enema bag 34 is matched, the number of the speed regulating devices 4 is described: the resistance of the liquid passing through the speed regulating device 4 is relatively smaller when the number of the speed regulating device 4 is 2 to 5, in this case, if the flow rate of 30 to 50 milliliters per minute is to be achieved, the height of the enema bag 34 may be relatively lower, generally about 30 to 50 centimeters, because the smaller nodes enable the liquid to pass through the valve more smoothly, the pressure difference generated by the lower height of the enema bag 34 can meet the corresponding flow rate requirement, when the number of the speed regulating device 4 is 6 to 10, the resistance of the liquid passing through is correspondingly increased along with the increase of the number of the nodes, at this time, in order to achieve the flow rate of 30 to 50 milliliters per minute, the height of the enema bag 34 may need to be increased to about 50 to 80 centimeters, the medium number of the nodes generate a certain resistance to the liquid flow, the higher pressure difference is needed to push the liquid through the valve so as to achieve the expected flow rate, when the number of the speed regulating device 4 is 11 to 15, the resistance of the liquid passing through the valve is larger, and the flow rate of 30 to 50 milliliters per minute is to be achieved, the height of the enema bag 34 may be about 80-120 cm. The flow path of the liquid in the valve is more complicated due to the fact that more nodes, larger pressure difference is needed to overcome resistance, the liquid is guaranteed to pass through at proper flow rate, therefore, medical staff can use different numbers of speed regulating devices 4 according to treatment needs of patients in a combined mode, treatment effects and treatment adaptation diversification are improved, in practical application, the optimal combination of the number of the nodes of the speed regulating devices 4 and the height of the enema bag 34 is needed to be determined through experiments and practical measurement, and flexible adjustment is needed according to specific equipment, liquid and patient conditions.
