[0031] In this embodiment, the closure of the infusion tube 1 does not mean sealing. The infusion tube 1 is provided with a port connected to the liquid containing cavity and the outside, such as a liquid flow end, through which the second liquid can flow into or out of the liquid containing cavity. The wall of the infusion tube 1 is arranged to form the liquid containing cavity, and the wall of the infusion tube 1 is transparent, so that the position of the first liquid in the liquid containing cavity can be easily observed and confirmed from the outside.

[0032] The liquid containing cavity of the infusion tube 1 forms a flow channel for the first liquid and the second liquid to flow. The infusion tube 1 is arranged in a vertical direction, and the first liquid is located at the lower end of the infusion tube 1. The top surface of the first liquid has a certain height, which is used as a positioning mark. The top surface of the first liquid is adjusted to a position higher than the liquid flow end. When the second liquid flows into the liquid containing cavity, the liquid in the liquid containing cavity increases, and the top surface of the first liquid rises; when the second liquid flows out of the liquid containing cavity, the liquid in the liquid containing cavity decreases, and the top surface of the first liquid decreases. By controlling the volume of the second liquid in the liquid containing cavity, the height of the top surface of the first liquid is adjusted, and the top surface of the first liquid is used as the reference height position (drainage tube 4) to reduce the difficulty of confirming the reference height position of the drainage tube 4 and the difficulty of adjusting the height, thereby ensuring the treatment effect, facilitating nursing, and reducing the pain of patients.

[0033] like Figure 2 As shown, as an optional embodiment, the medical ventricular drainage positioning device also includes a syringe 2, the output end of the syringe 2 is connected to the liquid flow end, and the syringe 2 is used to inject the second liquid into the liquid containing cavity, or to extract the second liquid in the liquid containing cavity.

[0050] like Figure 3 As shown, as an optional implementation, the medical ventricular drainage positioning device further includes a bracket 3 , and the bracket 3 is used to hang the infusion tube 1 .

[0051] Based on the foregoing embodiments, in this embodiment, the bracket 3 has a sufficient height to hang the infusion tube 1, so that the top surface of the first liquid can be raised to a sufficient height to facilitate confirmation of the reference height position of the flow tube and height adjustment.

[0052] like Figure 3 As shown, in some embodiments, the medical ventricular drainage positioning device further includes a connected drainage tube 4 and a drainage bag 5. The drainage tube 4 and the drainage bag 5 are both hung on the bracket 3.

[0053] As an optional implementation, the bracket 3 is provided with a scale mark for displaying the height.

[0054] With the above implementation, the scale mark can indicate a clear height position, so as to facilitate confirmation of the reference height position of the flow tube and height adjustment.

[0055] The first tube 11, the second tube 12, the connecting tube 16 and the atmosphere connecting tube 15 in the embodiment of the present application are all small in size, transparent and flexible, not easy to bend, and can be placed on the bed. They can be fixed on the patient's head or on the bracket 3 with adhesive tape. The zero point alignment is convenient and accurate, and can be observed and adjusted in real time to ensure the accuracy of the drainage height, thereby ensuring the therapeutic effect of the drainage, while reducing the difficulty of nursing work.

[0056] As an optional implementation, the first liquid and the second liquid have different colors.

[0057] Based on the foregoing embodiments, in this embodiment, the first liquid and the second liquid have different colors, and a clear interface can be formed between the two liquids, which facilitates identification of the first liquid and the second liquid.

[0058] Optionally, the first liquid is a transparent liquid; and the second liquid is a blue liquid.

[0059] Optionally, the first liquid is a blue liquid; and the second liquid is a transparent liquid.

[0060] like Figure 3 As shown, based on the above-mentioned embodiment, in a specific embodiment, the injection port of the syringe 2 is connected to the liquid flow end of the first three-way structure 13 through the connecting tube 16, and the connecting tube 16 and the liquid flow end, as well as the injection port of the syringe 2 and the connecting tube 16 are all interference connected, and can also be connected through a conversion joint to achieve a detachable connection. A body accommodating cavity is provided in the syringe 2, and the body accommodating cavity contains a second liquid, and the second liquid is a colored liquid, such as a blue aqueous solution. The capacity of the body accommodating cavity is greater than or equal to 50 ml and less than or equal to 150 ml. The first tube 11 and the second tube 12 are connected through the first three-way structure 13 and the second three-way structure 14, and form an annular solution cavity.

[0061] Clinically, when the patient lies flat, the ears on both sides are at the same level, the drainage tube 4 is led out from the cerebrospinal fluid drainage point, passes through the highest point of the drainage tube 4, and flows into the drainage bag 5 below the highest point. Referring to the scale on the bracket 3, the height difference between the highest point of the drainage tube 4 and the drainage zero point (the horizontal plane of the external auditory canal) can be adjusted.

[0062] The syringe 2 is set at a position lower than the drainage zero point, that is, the horizontal plane of the external auditory canal, and the infusion tube 1 is hung on the bracket 3. After the syringe 2 expels the air, the colored second liquid is injected, and the top surface of the colorless liquid set in the lower sections of the first tube 11 and the second tube 12 gradually rises and is flush with the external auditory canal. At this time, the top surface of the colorless liquid is the drainage zero point. According to the position of the drainage zero point on the scale mark of the bracket 3, the height of the highest point of the drainage tube 4 can be accurately and conveniently adjusted on the bracket 3. For adult patients, the drainage height, that is, the height difference between the highest point of the drainage tube 4 and the drainage zero point, is within the range of 100 mm to 150 mm, and is adjusted at any time according to the doctor's advice according to the drainage speed. When the patient eats, raises the head of the bed, or changes position, the syringe 2 is used to inject and extract the liquid, which can quickly and easily find the drainage zero point, and then accurately adjust the drainage height.
