[0031] Specifically, the sound transmission part 300 includes a linkage rod 310 connected to the top of the drainage bag 100, a striking piece 320 elastically connected to the two lateral ends of the linkage rod 310, and an elastic piece 330 for suspending the linkage rod 310; the striking piece 320 is made of steel and is made of a hollow triangular prism structure, so that it can make a sound due to vibration when it hits a metal part; the sounding platform 210 is in the shape of a rectangular strip and its top surface is a downward inclined surface, and a sounding piece 340 made of steel material that is in sliding contact with the striking piece 320 is hung on the inclined surface of the sounding platform 210, and the sounding piece 340 is in the shape of a rectangular hollow shell. According to the law that sound propagates by generating vibration, the striking piece 320 strikes the struck piece 320 to cause it to resonate and make a sound; When more than half of the fluid is accumulated in the drainage bag 100, the linkage rod 310 is automatically driven down, and then the striking piece 320 is driven to slide down along the upper sounding platform 210 and be squeezed and flipped up, until the gravity of the fluid accumulated in the drainage bag 100 drives the striking piece 320 to slide over the upper sounding platform 210, then the striking piece 320 instantly rebounds and flips down and hits the middle sounding platform 210, and the striking piece 320 hits the sounding piece 340 to produce resonance and emit a sharp and continuous sound, which is a signal to release the fluid accumulated in the drainage bag 100. The patient's family members do not need to keep an eye on the fluid accumulation in the drainage bag 100 all the time, and can release the accumulated fluid in time under the condition of accompanying the patient.

[0032] Furthermore, a hanging tube 311 is vertically provided on the middle side wall of the linkage rod 310, and the hanging tube 311 is sleeved with the edge of the drainage bag 100. A support block 220 plugged with the hanging tube 311 is vertically provided on the top inner wall of the other protective cover 200; wherein the width of the support block 220 is smaller than the inner width of the hanging tube 311, and when the two protective covers 200 are put together, the support block 220 can be rotatably plugged with the hanging tube 311, thereby stably supporting the drainage bag 100 with effusion; A spring sheet 321 is fixedly connected between the striking piece 320 and the linkage rod 310. The spring sheet 321 is made of spring steel in a straight sheet shape and is welded and fixed at both ends. The length of the linkage rod 310 and the pair of spring sheets 321 is at most equal to the distance between the bottom ends of a pair of sounding platforms 210 of the same height, so that when the striking piece 320 is pushed up by the sounding platform 210, it can drive the spring sheet 321 to bend upward and deform and pass through the sounding platform 210. After the striking piece 320 passes through, it instantly hits the sounding piece 340 of the sounding platform 210 below due to the rebound action of the spring sheet 321, that is, the striking piece 320 itself resonates and makes a sound.

[0033] Furthermore, the elastic member 330 is a rubber band or a spring and its bottom end is bonded to the top surface of the linkage rod 310. A hanging block 331 is fixedly provided on the top of the elastic member 330. A clamping block 202 engaged with the hanging block 331 is provided on the top of the protective cover 200, so that the linkage rod 310 uses the elastic force of the elastic member 330 to resist the weight of the accumulated fluid in the drainage bag 100, so that it gradually passes through each pair of sounding platforms 210, forming multiple beeps to remind people; the side walls at both ends of the linkage rod 310 are provided with card grooves 312, and the inner width of the card groove 312 is greater than the width of its outer port, such as T-type, L-type and water drop type, so as to form a limiting structure, and the inner wall of the protective cover 200 is symmetrically provided with limiting strips 203 corresponding to the two card grooves 312, so that the linkage rod 310 is restricted to move up and down, and the drainage bag 100 is stably suspended.
