Summary of the Utility Model

[0004] In view of the above problems, the purpose of the utility model is to provide an external ventricular quantitative drainage bottle, aiming to solve the technical problems.

[0005] The utility model adopts the following technical scheme:

[0015] In order to make the purpose, technical solution and advantages of the present utility model clearer, the present utility model will be further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0016] In order to illustrate the technical solution described in the present utility model, the following will be described through specific embodiments.

[0017] As Figure 1 、 2 shown, the extracerebral ventricular quantitative drainage bottle provided in this embodiment includes a bottle body 1. A negative pressure pipe 2 is connected to the top of the bottle body 1. An inlet pipe 3 and a drain pipe 4 are connected to the bottom of the bottle body 1. The top of the inlet pipe 3 is bent downward. There is also a partition board 5 inside the bottle body 1. The inlet pipe 3 extends out of the partition board 5. A liquid dropping port 61 is opened at a position near the edge of the partition board 5. The liquid dropping port 61 is connected downward with a short pipe 62. An adjustment switch 63 for controlling the opening and closing of the short pipe 62 is provided on the outer wall of the bottle body. A balance pipe 7 communicating with the space below the partition board 5 is also provided on the partition board 5. The end of the balance pipe 7 extends out of the bottle body 1 and is provided with a switch air valve 71. On the partition board 5, the position of the liquid dropping port 61 is the lowest. It is convenient for the accumulated liquid to be discharged from the liquid dropping port 61 into the lower layer space of the partition board.

[0018] In this structure, there is a partition inside the bottle body of the drainage bottle. The partition is an integral structure with the bottle body, and the lower space of the partition is the quantitative space. Under normal circumstances, the regulating switch is in the open state and the switch air valve is in the off state. The negative pressure tube is connected to the negative pressure machine, and a stable negative pressure is maintained inside the bottle body. There is a liquid inlet tube and a liquid discharge tube (both are also equipped with valves) at the bottom of the drainage bottle. The liquid inlet tube is connected to the patient's cerebral ventricle through a drainage needle, and the liquid outlet tube is connected to the liquid storage bag. The volume of the liquid storage bag is larger than that of the drainage bottle.

[0019] The accumulated fluid extracted by negative pressure will flow into the lower space. When the lower space is full, the regulating switch is turned off (even if the regulating switch is not turned off in time for drainage, there is a small amount of accumulated fluid in the upper layer of the partition, which does not affect the quantitative drainage). Before drainage, the switch air valve is opened, and then the valve of the liquid discharge tube is opened. The accumulated fluid in the lower space of the partition is discharged into the liquid storage bag. After completion, each switch returns to the initial state. Since the upper and lower spaces of the partition are isolated during the drainage process, the upper space can continue to store liquid, so there is no need to pause the negative pressure machine, ensuring safety. Another advantage of setting the partition is that when the accumulated fluid flows into the lower space, even if the drainage bottle is accidentally shaken, the accumulated fluid will not be sucked out from the negative pressure tube, ensuring the stable operation of the negative pressure machine.

[0020] At the same time, since the accumulated fluid fills the lower space before each drainage, each drainage is also quantitative. By recording the number of drainage times, the volume of the accumulated fluid in the liquid storage bag can be accurately recorded. In the existing method, the drainage volume is not quantitative each time, and the accumulated fluid volume of the patient cannot be accurately recorded.

[0021] In addition, as a preferred structure, as shown in Figure 3 , a sealing cover 8 is provided at the top of the bottle body 1. There is a cavity under the sealing cover 8, and a circle of air holes 81 is opened at the bottom edge of the cavity. The negative pressure tube 2 is installed at the center position of the sealing cover 8. If the drainage is not carried out in time, when the lower space is full, the accumulated fluid will accumulate in the upper space. To prevent the accumulated fluid inside from being sucked out from the negative pressure tube due to accidental shaking, the lower layer of the sealing cover in this structure is a cavity, and the bottom plate of the cavity can play a certain blocking effect on the accumulated fluid, preventing the splashed accumulated fluid from contacting the negative pressure tube. Further, a buffer bottle 9 can be connected to the end of the negative pressure tube 2. The buffer bottle 9 is connected to the negative pressure machine. Even if a small amount of accumulated fluid is sucked out, it will not enter the negative pressure machine through the buffering of the buffer bottle 9.

[0022] In addition, as shown in the figure, a pair of lifting lugs 11 are also provided at the top of the bottle body 1, and a suspension rope 12 is connected between the pair of lifting lugs 11. The drainage bottle is suspended by the suspension rope 12.

[0023] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
