Meanwhile, as shown in fig. 7, 10 and 11, in the ascites diversion control device, the lower ends of the firsttelescopic rod 5 and the secondtelescopic rod 4 are respectively hinged with theweighing platform 2 and thebase 1, so that the firsttelescopic rod 5 and the secondtelescopic rod 4 can be rotated forwards from a vertical state to a horizontal state, and the hinged parts of the firsttelescopic rod 5 and the secondtelescopic rod 4 are respectively provided with apositioning mechanism 20 for locking the horizontal state and the vertical state of the firsttelescopic rod 5 and the secondtelescopic rod 4; the technical characteristics are that, on one hand, when the ascites drainage control device is in a use state, the firsttelescopic rod 5 and the secondtelescopic rod 4 can be adjusted to and maintained in a vertical state, so that necessary supports can be provided for thesuspension beam 17 and the placingseat 9 respectively, and on the other hand, the firsttelescopic rod 5 and the secondtelescopic rod 4 can be rotated forwards to and maintained in a horizontal state, so that the ascites drainage control device can be switched to a folding state, and the whole volume of the device is reduced;

the technical feature can be implemented by using the prior art, for example, as shown in fig. 2 and 3, ahinged support 3 with a rotation angle limiting function can be respectively arranged above theweighing platform 2 and thebase 1, and the lower ends of the firsttelescopic rod 5 and the secondtelescopic rod 4 are respectively rotatably connected with thehinged supports 3 through rotating shafts, so that the technical requirement that the firsttelescopic rod 5 and the secondtelescopic rod 4 can be rotated forward from a vertical state to a horizontal state can be met, and thepositioning mechanism 20 can use a positioning bolt, so that the technical requirement that the firsttelescopic rod 5 and the secondtelescopic rod 4 can be locked can be met;

however, considering that thepositioning mechanism 20 is a positioning bolt, the positioning bolt needs to be manually adjusted after the firsttelescopic rod 5 and the secondtelescopic rod 4 are rotatably adjusted each time, which is troublesome to operate, and considering that most of external force applied to the firsttelescopic rod 5 and the secondtelescopic rod 4 is downward acting force in the use process of the ascites drainage control device; based on this, thepositioning mechanism 20 preferably adopts a matching structure of a spring plunger and positioning holes, taking the firsttelescopic rod 5 as an example, the side wall of the lower end of the first telescopic rod is provided with two positioning holes, the inner wall of thehinged support 3 is provided with the spring plunger matched with the positioning holes, when the firsttelescopic rod 5 is in a vertical state, the telescopic end of the spring plunger just extends into the corresponding positioning hole, the positioning force provided by the spring plunger and the positioning holes for the firsttelescopic rod 5 is enough to support thedrainage bag 25, when the upper end of the firsttelescopic rod 5 is manually pushed forwards, the spring plunger is forced to be separated from the positioning holes, when the firsttelescopic rod 5 is rotated to a horizontal state, the telescopic end of the spring plunger just extends into the other positioning hole, i.e. the firsttelescopic rod 5 is locked in a horizontal state, and similarly, thepositioning mechanism 20 on the secondtelescopic rod 4 can also adopt the same structure; after thepositioning mechanism 20 adopts the structure of the spring plunger and the positioning hole, the firsttelescopic rod 5 and the secondtelescopic rod 4 can meet the supporting requirements on thesuspension beam 17 and the placingseat 9, and the technical effect of automatic locking after state adjustment is achieved.

Meanwhile, due to the existence of thearch part 28 in thesuspension beam 17, after the connectingpipe 18 is connected with thedrainage bag 25, thesuspension beam 17 does not form an obstacle to the up-and-down extension of the tail section part of the connectingpipe 18, the connectingpipe 18 can be connected with thedrainage bag 25 in a state of tending to natural extension, the acting force on thedrainage bag 25 is reduced, and in addition, the connection and separation operation of the connectingpipe 18 and thedrainage bag 25 is more convenient and smooth.

Referring to fig. 7 and 8, the ascites drainage control device adopts an intelligent design, and can realize functions of timed drainage, constant-speed drainage, quantitative drainage and the like according to preset drainage parameters in clinical drainage operation, so that the aim of intelligent automatic drainage control is fulfilled, the labor burden is saved, and the safety, stability and accuracy of drainage operation are improved; the ascites drainage control device is matched with theconventional drainage bag 25 and thedrainage tube 26 for use, and the existing structures of thedrainage bag 25 and thedrainage tube 26 do not need to be changed, so that the ascites drainage control device is easier to popularize and use; this ascites drainage controlling means has user state and fold condition based on adjustable design, and the state switches very conveniently, and the volume is very small and exquisite under fold condition, and it is little to place occupation space, and it is very convenient to remove to carry.
