For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations. The present utility model will be described in detail below with reference to the accompanying drawings and in conjunction with the embodiments.

As the first embodiment of the present invention, an enema device, referring to Figures 1 and 2, includes an enema bag 1 for accommodating an enema solution, and the enema bag 1 communicates with an enema tube 3 through an infusion tube 2 , wherein the enema tube 3 is used for inserting into the colon from the anus through the rectum; the infusion tube 2 is provided with a switch valve 4 that controls the opening/closing of the infusion tube 2, and the switch valve 4 can only control all The switch structure for opening/closing the infusion tube 2, such as a clip; it can also be a control structure that can control the flow rate of the infusion tube 2, such as a retention enema disclosed in the Chinese utility model patent application number CN202120704214.2. The flow controller in the tube combination; also includes a collection device 5, which is communicated with the enema tube 3 through a collection tube 6, and the collection tube 6 is provided with a control of the collection tube 6 On/off switch valve 4.

Preferably, a pressure difference is formed between the colon filled with the enema liquid and the collecting device 5, and through the pressure difference, the enema liquid and the excreta are sequentially discharged along the enema tube 3 and the collecting tube 6, and drain into the collection device 5. Specifically, during the enema, it is necessary to first close the on-off valve 4 on the collecting pipe 6 to cut off the connection between the enema pipe 3 and the collecting device 5 , and then open the on-off valve on the infusion pipe 2 4. Make the enema bag 1 and the enema tube 3 communicate with each other. At this time, the enema liquid will be poured into the enema bag 1 along the infusion tube 2 and the enema tube 3 in turn. In the colon of the patient; when the enema liquid is perfused, close the on-off valve 4 on the infusion tube 2 and open the on-off valve 4 on the collecting tube 6, at this time, the enema bag 1 is connected with the enema tube 3 The passage is blocked, and the enema tube 3 is connected with the collection device 5. Since the colon is filled with enema liquid and softened and diluted excrement, a certain intra-abdominal pressure is formed and the human body is also excreted. The human body's own excretion action can discharge the enema liquid and softened excrement into the collecting device 5 through the enema tube 3 and the collecting tube 6 in sequence to complete the collection.

Preferably, the collection device 5 can be a simple collection bottle or collection bag with an opening, and the air pressure in the collection bottle or collection bag is communicated with the atmospheric pressure, and is lower than the air pressure in the colon filled with enema fluid during excretion. The intra-abdominal pressure forms a relatively low pressure area, so that the enema liquid and the softened excrement can be discharged into the collecting device 5 through the enema tube 3 and the collecting tube 6 in sequence. Further, in order to better collect the enema liquid and the softened excrement to achieve a more thorough collection effect, the collection device 5 preferably can better form a negative pressure drain 502 in the negative pressure area, so The negative pressure drainage device 502 is communicated with the enema tube 3 through the collecting pipe 6 , and the negative pressure drainage device 502 constitutes a accommodating device for collecting the enema liquid and excrement. Before collecting, the exhaust port 5022 can be opened to discharge the air in the negative pressure inducer 502, and then the exhaust port 5022 can be closed. At this time, a negative pressure area will be formed in the negative pressure inducer 502 . After the negative pressure area is formed, the on-off valve 4 on the collecting pipe 6 is opened, under the dual action of air pressure and the human body's own excretion action, the middle enema of the anorectum and the softened excrement can be more smoothly discharged into the room. in the negative pressure drain 502. The specific internal structure of the negative pressure drain 502 and the specific operation method can refer to a convenient metering negative pressure drain and a negative pressure drain kit disclosed in Chinese Utility Model Patent Application No. CN201921381692.3. More details.

Preferably, for the same patient, multiple enema operations may be required in a short period of time. If a new enema device needs to be taken for each enema, the medical cost will be too high; if one enema device is used every time, Then, the enema tube 3 inserted into the human body is likely to cause infection. Based on this, in this embodiment, the infusion tube 2 , the enema tube 3 and the collecting tube 6 are connected through a three-way valve 7 provided with three valve ports to form a “Y”-shaped Pipe connection structure, wherein at least the enema tube 3 is connected to the three-way valve 7 through a detachable connection structure; wherein the detachable connection structure means: one end of the enema tube 3 is provided with an external thread, or is provided with an external thread. There is an interface with an external thread; the valve port of the three-way valve 7 connected to the enema tube 3 is provided with a corresponding internal thread, and the enema tube 3 is connected to the three through a detachable threaded connection structure. on valve 7. Of course, the detachable connection structure may also be a commonly used detachable connection structure for pipes, such as a snap-on connection and a plug-in connection. In this way, every time an enema is performed, only a new enema tube 3 needs to be replaced, which can save medical costs and avoid infection.

It should be noted that in actual use, due to the different capacity of enema liquid that can be accommodated in each person's anorectum, the amount of enema liquid that can be tolerated by each person is also different. Therefore, there is often a quantitative Enema solution requires multiple enemas. In this case, during the second or third collection, since part of the enema liquid has been collected in the negative pressure drain 502, it is difficult to squeeze it to form a negative pressure area; therefore, in order to A continuous and stable negative pressure area can be formed in the collection device 5 to optimize the collection effect of the enema liquid in the whole process.
