Fig. 2 is the schematic diagram of the pressure conversion drainage system of another embodiment of this utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, this utility model is described in further detail.
Fig. 1 and Fig. 2 show schematically show a kind of pressure conversion drainage system according to a kind of embodiment of the present utility model, this pressure conversion drainage system comprises the negative pressure ball 1 that is provided with inlet opening 11, bag container 6 and the three way cock 3 being connected negative pressure ball 1 and bag container 6, the inlet opening 11 of negative pressure ball 1 is communicated with one end of the first conduit 2, the other end of the first conduit 2 is communicated with first port of three way cock 3, second port of three way cock 3 is communicated with one end of drainage tube 4, multiple aperture 41 is provided with at the sidewall of the other end of drainage tube 4, such drainage tube 4 is except using the main aperture of drainage tube 4 to suck blood, multiple apertures 41 of sidewall can also be used drain is carried out when amount of bleeding is few, just can strengthen the ability that drainage tube 4 sucks blood, thus strengthen the drain ability of drainage tube 4, the 3rd mouthful of three way cock 3 is communicated with one end of the second conduit 5, the other end of the second conduit 5 is communicated with bag container 6, three way cock 3 is provided with traffic organising switch 31, traffic organising switch 31 makes two ports of three way cock 3 be communicated with all the time, another one port is not communicated with two ports be connected, namely when first port of three way cock 3 is communicated with the second port third connectivity mouth and the first port and the second port obstructed, when second port is communicated with third connectivity mouth the first port and the second port and third connectivity mouth obstructed, when first port is communicated with third connectivity mouth the second port and the first port and third connectivity mouth obstructed, when the amount of bleeding of patient wound is large, directly traffic organising switch 31 is pushed the second port to be communicated with third connectivity mouth, make drainage tube 4 directly in the mode of normal pressure drain by blood drainage in bag container 6.When the amount of bleeding hour of patient wound, first traffic organising switch 31 is pushed the second port to be communicated with third connectivity mouth, negative pressure ball 1 is extruded, air is entered in bag container 6, then traffic organising switch 31 is pushed the first port to be communicated with the second port, by the effect of negative pressure ball 1 make drainage tube 4 in the mode of negative pressure drainage by blood drainage in negative pressure ball 1, after being full of blood in negative pressure ball 1, traffic organising switch 31 is returned to the state that the second port is communicated with third connectivity mouth, extruding negative pressure ball 1, blood in negative pressure ball 1 is clamp-oned in bag container 6, after negative pressure ball returns to negative pressure state, traffic organising switch 31 is returned to the state that the second port is communicated with third connectivity mouth to continue in the mode of negative pressure drainage, blood to be drained in negative pressure ball 1 by drainage tube 4, repeat aforesaid operations, until patient does not need with negative pressure mode drain.Certainly, also can a negative pressure exhaust control hole 12 be set on negative pressure ball 1 again, negative pressure exhaust control hole 12 is provided with a port lid 13, port lid 13 and negative pressure exhaust control hole 12 connected mode can adopt the mode of screw thread to be flexibly connected, when needing to use negative pressure exhaust control hole 12 to discharge the air in negative pressure ball 1, turn on port lid 13, again port lid 13 is screwed back after air in negative pressure ball 1 is drained, should be noted that port lid on negative pressure exhaust control hole 12 13 twist good after the phenomenon of gas leakage can not be had to occur.The first check valve 42 is provided with in drainage tube 4, the second check valve 51 is provided with in the second conduit 5, certainly, in order to easily manufactured, also the second check valve 51 can be set in the junction of bag container and the second conduit 5, first 42, check valve allows drainage tube 4 by blood drainage in negative pressure ball 1, and does not allow blood reflux to drainage tube 4 place; Second 51, check valve flows in bag container 6 after allowing drainage tube 4 that the blood flow to behind blood drainage to the second conduit 5 place in bag container 6 or in negative pressure ball 1 is flow to the second conduit 5 place, and does not allow the blood in bag container 6 to be backflowed to drainage tube 4 place or backflow in negative pressure ball 1 by the second conduit 5.The surface that the surface of bag container 6 is marked with containing mark 61 and negative pressure ball 1 is marked with containing mark 14, be used for the blood volume determining that patient is run off, the lower end of bag container 6 is provided with leakage fluid dram 61, and leakage fluid dram is provided with valve 63, and the effect of leakage fluid dram 61 is the blood in discharge bag container 6.Conveniently hang up bag container 6 and negative pressure ball 1, be provided with at bag container 6 and buckle 64, negative pressure ball 1 is provided with and buckles 15.
