Specifically, the front end of the transparent outer cover 2 is connected with a pasting ring 3, the pasting ring 3 can be pasted at the anus of the patient, so that the anus of the patient and the inside of the transparent outer cover 2 are combined to form a closed space, the closed space is used for receiving the leaked waste liquid during clystering in the state shown in fig. 1, and is used for receiving the cleaning liquid for cleaning the cannula 1 in the state shown in fig. 2; the rear end of the transparent outer cover 2 is fixed with a sliding sleeve 7, the sliding sleeve 7 is in sliding fit with the cannula 1, and a liquid guide cavity is arranged in the sliding sleeve 7. Thereby allowing relative movement between the transparent outer cover 2 and the cannula 1 to vary the length of the cannula 1 inside the enclosed space and thus the length of the cannula 1 inserted into the anus of the patient.

The negative suction mechanism 4 is connected with the liquid guide cavity of the sliding sleeve 7 through a liquid suction pipe so as to suck out dirty liquid or cleaning liquid in the closed space. A supply mechanism 5, the supply mechanism 5 including an enema supply unit 51 and a cleaning liquid supply unit 52; the enema supply unit 51 and the cleaning liquid supply unit 52 both comprise a shell, and a liquid storage cavity is defined in the shell; the movable piston 53 is installed in the liquid storage cavity, a piston rod 55 and a first spring 54 are fixed on one side, away from the switching valve 6, of the piston 53, the piston rod 55 and the spring 54 are connected with the inner wall of the liquid storage cavity, the piston 53 is attached to the inner wall of the liquid storage cavity to play a limiting role, and therefore the whole supply mechanism 5 is enabled to form a positive pressure supply state, and an additional supply pump is not needed to be arranged in the positive pressure supply state.

As can be seen from the above, the overall device includes two usage states shown in fig. 1 and 2 when in specific use, and the usage principle of the two usage states is as follows:

when inserting an enema, the transparent cover 2 is pulled toward the front end of the cannula 1, thereby bringing the transparent cover 2 into an expanded state shown in fig. 2 in which the front end of the cannula 1 is confined inside the cover 2; then, the pasting ring 3 is pasted at the anus of the patient, so that the anus of the patient and the inside of the transparent outer cover 2 are combined to form a closed space; then, the sliding sleeve 7 is held, the cannula 1 is pulled to realize the adjustment of the insertion depth of the cannula 1, and preferably, in order to observe the insertion depth, a display scale can be arranged on the surface wall of the cannula 1; after the structure of the regulation of the insertion depth is completed, the front end position of the insertion tube 1 is observed through the transparent outer cover 2, the front end of the insertion tube 1 is ensured to be corresponding to the anus of the patient, the insertion tube 1 and the sliding sleeve 7 are finally held, the front end of the insertion tube 1 is inserted into the anus of the patient, and the sliding sleeve 7 is driven to synchronously move simultaneously, so that the sliding sleeve 7 is close to the pasting ring 3, the retraction of the transparent outer cover 2 is completed, and the state shown in the figure 1 is formed. In the state of fig. 1, the switching valve 6 is adjusted to conduct the cannula 1 and the enema supply unit 51, so that the enema is introduced into the lumen of the cannula 1 through the switching valve 6 and finally discharged into the rectum of the patient through the outlet hole at the front end of the cannula 1, thereby completing the enema. In the enema process, dirty liquid discharged through the anus of a patient flows into the closed space formed by the transparent outer cover 2 and the sticking ring 3, and the closed space is communicated with the negative suction mechanism 4 through the liquid guide cavity and the liquid suction pipe, so that the collection and the cleaning of the dirty liquid can be completed in time.

When the cannula 1 is taken out, the cannula 1 and the sliding sleeve 7 are held, the adhesive ring 3 is pressed, so that the adhesive ring 3 is prevented from falling off, and the transparent outer cover 2 is unfolded under the condition that the sliding sleeve 7 and the adhesive ring 3 are away from each other, so that the state shown in fig. 2 is formed; in this state, if the next enema is still to be performed, the switching valve 6 is adjusted to conduct the cannula 1 and the cleaning solution supply unit 52, so that the cleaning solution is discharged into the transparent cover 2 through the cannula 1, and is discharged out of the negative suction mechanism 4 through the liquid guide chamber and the liquid suction tube, thereby effectively cleaning the outer wall of the cannula 1 and the inner wall of the transparent cover 2 by the flow of the cleaning solution, and also effectively preventing the cannula 1 from being exposed to the air after being taken out.

Further, the adjustment structure and the adjustment principle of the switching valve 6 are as follows:

structure of the product

A limiting sleeve 66 is sleeved on one side of the valve body 61, the rack 65 is matched inside the limiting sleeve 66, and the limiting sleeve 66 and the rack 65 can relatively slide along the axial direction of the screw rod 63. Two moving plates 68 are connected to one side of the valve body 61 in a sliding manner, the two moving plates 68 are symmetrically distributed on two sides of the gear 64, and the rack 65 is fixed on one of the moving plates 68; the two moving plates 68 are both in sliding fit inside the limiting sleeve 66, and a second spring 67 is connected between the two moving plates 68 and the limiting sleeve 66.

Principle of

In fig. 4, the switching valve 6 is in a closed state, at this time, the limiting sleeve 66 is sleeved on one side of the valve body 61, and the valve core 62 is positioned at the center of the inner cavity, so that the two liquid inlet holes and the two liquid outlet holes are both sealed;

in fig. 1, the switching valve 6 is in a state of conducting the cannula 1 and the enema liquid supply unit 51; to achieve this state, the position restricting sleeve 66 is pushed in a direction away from the valve body 61, whereby the position restricting sleeve 66 is disengaged from the valve body 61 while the second spring 67 is stretched; then, the limiting sleeve 66 is moved leftwards (in the direction shown in fig. 1), so that the two moving plates 68 and the rack 65 are driven to move synchronously, the rack 65 drives the gear 64 to rotate through the meshing action when moving, and further drives the screw rod 63 to rotate, the screw rod 63 forms spiral transmission with the valve core 62 when rotating, so that the valve core 62 is driven to move towards the corresponding liquid inlet hole of the cleaning liquid supply unit 52, and the conduction of the corresponding liquid inlet hole of the enema liquid supply unit 51 is realized. Further, the enema is completed by the urging of the first spring 54 and the piston 53 in the enema liquid supply unit 51.

In fig. 2, the switching valve 6 is in a state of conducting the cannula 1 and the cleaning liquid supply unit 52; this state is achieved by the same principle as the states of the conducting cannula 1 and the enema supply unit 51, and is different in that the direction in which the stopper 66 is moved is opposite to the direction in which the conducting cannula 1 and the enema supply unit 51 are moved.

In summary, it can be seen from fig. 1, 2 and 4 that: when the stop collar 66 is positioned at the leftmost side in the direction shown in the figure, the switching valve 6 conducts the cannula 1 and the enema liquid supply unit 51; when the limiting sleeve 66 is arranged at the middle position and sleeved on the valve body 61, the switching valve 6 is closed; when the position restricting sleeve 66 is positioned at the rightmost side in the direction shown in the drawing, the switching valve 6 conducts the insertion tube 1 and the cleaning liquid supply unit 52; therefore, the limiting sleeve 66 can be used for realizing accurate positioning of the whole switching valve 6, the operation is simple, and the phenomenon of error adjustment can be effectively avoided.
