[0026] Reference Figures 1 to 3 In some embodiments, according to the medical drainage device of the utility model, the medical drainage device comprises:
[0027] The drainage catheter 100 is used to drain the accumulated fluid and gas from the patient's body. The front end of the drainage catheter 100 is placed in the part of the patient's body that needs drainage;
[0028] A negative pressure drainage bottle 200 is used to buffer the accumulated fluid and gas. The negative pressure drainage bottle 200 includes at least a first inlet 210 and a first outlet 220. The rear end of the drainage catheter 100 is connected to the first inlet 210 of the negative pressure drainage bottle 200. The end of the first inlet 210 is inserted into the negative pressure drainage bottle 200 through a stepped spiral head.
[0029] The liquid storage device 300 is used to store accumulated fluid and gas. The liquid storage device 300 at least includes a second inlet 310 and a second outlet 320. The second inlet 310 is connected to the first outlet 220 of the negative pressure drainage bottle 200 through a connecting hose.
[0030] Specifically, one end of the drainage catheter 100 is placed in the patient's chest cavity, abdominal cavity or other parts that require drainage, and the other end of the drainage catheter 100 is connected to the negative pressure drainage, and the outlet of the negative pressure drainage bottle 200 is connected to the liquid storage device 300 through a hose. Before starting drainage, first connect the equipment, check that the three-way valve set on the drainage catheter 100 is in a closed state, the first outlet 220 of the negative pressure drainage bottle 200, namely the liquid discharge port and the air exhaust port, are both in a closed state, and the second outlet 320 of the liquid storage device 300 is in a closed state. After checking that everything is correct, turn on the switch of the first outlet 220 of the negative pressure drainage bottle 200 and the switch of the three-way valve of the drainage catheter 100 in turn to start the drainage operation.
[0031] After the drainage begins, under the negative pressure of the negative pressure drainage bottle 200, the patient's effusion and gas flow into the negative pressure drainage bottle 200 and the liquid storage device 300. If the patient discharges too much gas or effusion or as time goes by, the negative pressure in the negative pressure drainage bottle 200 decreases, and it becomes difficult to continue the drainage. At this time, the exhaust valve 230 of the negative pressure drainage bottle 200 can be opened to exhaust and then continue the drainage. Alternatively, the liquid and gas can be discharged at the second outlet 320 of the liquid storage device 300. After the liquid and gas are discharged, the second outlet 320 is connected to an aspirator, and the aspirator is turned on to evacuate the negative pressure drainage bottle 200 and the liquid storage device 300, so that the negative pressure drainage bottle 200 generates negative pressure again, and the drainage operation is continued. The effusion can be smoothly poured into the liquid storage device 300 for measurement. The above operations must meet the medical and health level to prevent infection.
[0032] The beneficial effects of the utility model are as follows:
[0033] In the present application, a liquid storage device 300 is additionally provided on the basis of the negative pressure drainage bottle 200. The outlet of the liquid storage device 300 is used to discharge the accumulated fluid and gas, which can achieve the effect of reducing the amount of accumulated fluid and / or gas pressure in the negative pressure drainage bottle 200 and the liquid storage device 300, reducing the gas pressure in the negative pressure drainage bottle 200 and the liquid storage device 300, and facilitating continuous drainage and metering of the drainage fluid.
[0034] In the prior art, the drainage catheter 100 and its accessories are used to drain blood. However, for infants and young children, especially for drainage after congenital heart surgery, the measurement is not accurate enough due to the gas removal.
[0035] Further, refer to Figure 1 and Figure 2 , further comprising an aspirator connected to the second outlet 320 of the liquid storage device 300. The aspirator is used to absorb the residual effusion and gas of the negative pressure drainage bottle 200 and the liquid storage device 300, so that they are in a negative pressure state.
[0036] Further, refer to Figure 1 and Figure 2 The liquid storage device 300 is a drainage bag, which includes at least a main bag outlet and a sub-bag outlet. The main bag outlet is connected to a drainage connector, the sub-bag outlet is connected to a sampling connector, and the aspirator is connected to the sampling connector via a suction hose.
[0037] In some embodiments, the drainage connector is used to drain the accumulated fluid, and the sampling connector is used to connect to an aspirator. After the aspirator is turned on, the negative pressure drainage bottle 200 and the drainage bag are evacuated so that the negative pressure drainage bottle 200 and the drainage bag maintain or enhance the negative pressure working state, thereby facilitating the discharge of accumulated fluid and gas from the patient's body.
[0038] Further, refer to Figure 1 and Figure 2 The liquid storage device 300 is a three-chamber drainage bottle, and the suction device is connected to the exhaust port of the three-chamber drainage bottle through a suction hose.
[0039] In some specific embodiments, if the patient has too much fluid accumulation, a larger capacity three-chamber drainage bottle can be selected. In this case, the aspirator can be connected to the exhaust port or other connection port of the three-chamber drainage bottle to absorb the gas in the negative pressure drainage bottle 200 and the three-chamber drainage bottle.
[0040] Further, refer to Figure 1 and Figure 2 The liquid storage device 300 is a urine bag, the inlet of the urine bag is connected to the second outlet 320 of the negative pressure drainage bottle 200 through a hose, and the suction device is detachably connected to the outlet of the urine bag through a hose.
[0041] In some embodiments, a low-cost suggested liquid storage device 300, such as a urine bag, may be selected to store accumulated fluid or urine.
[0042] Further, refer to Figure 1 and Figure 2 The top of the negative pressure drainage bottle 200 is also provided with an exhaust valve 230 for exhausting air.
[0043] Specifically, when a large amount of intracavitary gas is blocked above the accumulated fluid buffered in the negative pressure drainage bottle 200, the exhaust valve 230 of the negative pressure drainage bottle 200 can be temporarily opened to exhaust the fluid briefly so that the accumulated fluid in the body can be smoothly drained out.
[0044] Further, refer to Figure 1 and Figure 2 The drainage catheter 100 is provided with a switch valve 110 .
[0045] The switch valve 110 is used to control whether the drainage catheter 100 is connected to the negative pressure drainage bottle 200. When it is necessary to drain the accumulated fluid or connect an aspirator to absorb the gas, it is generally necessary to close the switch valve 110 first.
[0046] Further, refer to Figure 1 and Figure 2 , the switch valve 110 is a three-way valve.
[0047] Further, refer to Figure 1 and Figure 2 The negative pressure drainage bottle 200 and the liquid storage device 300 are respectively provided with scales. The negative pressure drainage bottle 200 and the liquid storage device 300 are respectively provided with scales to facilitate medical staff to measure and evaluate the amount of the outflowing effusion.

As long as the technical effect of the utility model is achieved by the same means, any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present disclosure shall be included in the scope of protection of the present disclosure. All should belong to the protection scope of the utility model. Within the protection scope of the utility model, its technical solution and / or implementation method can have various modifications and changes.
