DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] Example

[0022] See also Figure 1-Figure 4 , an intraocular fluid extraction device, comprising a film bag 1, a connecting plate 2 is provided on one side of the film bag 1, a handle 3 is provided on the connecting plate 2, a drain valve 4 is provided at one end of the film bag 1, and a pipe mouth cover 5 is provided on the drain valve 4;

[0023] A connector 6 is provided at the other end of the film bag 1, an interface thread 601 is provided inside the connector 6, a drainage tube 7 is provided inside the interface thread 601, a flow limiting buckle 8 is provided on the drainage tube 7, a clamping assembly 9 is provided at one end of the drainage tube 7, a flushing hole 10 is opened on the drainage tube 7, and a wire outlet hole 11 is provided on one side of the flushing hole 10.

[0024] In this embodiment, a clamping slot is provided on one side of the clamping plate 902, and a spring 901 is provided in the clamping slot on the clamping plate 902. By pressing one end of the clamping plate 902, the clamping plate 902 can be clamped to the patient's eye.

[0025] In this embodiment, the clamping assembly 9 includes a spring 901, a splint 902, and an anti-slip strip 903. The spring 901 is provided on one side of the drainage tube 7, the splint 902 is provided on one side of the spring 901, and the anti-slip strip 903 is provided on one side of the splint 902. The anti-slip strip 903 increases the friction force at the point where the drainage tube 7 contacts the patient's skin, thereby fixing the drainage tube 7.

[0026] In this embodiment, a flow limiting buckle 8 is slidably provided on the drainage tube 7, and the flow limiting buckle 8 is adjusted to adjust the drainage flow rate.

[0027] In this embodiment, one end of the drainage tube 7 is provided with an external thread 701, and the external thread 701 is meshed and connected with the interface thread 601. Through the threaded meshing connection, the drainage tube 7 can be quickly disassembled and installed.

[0028] In this embodiment, the port of the drain valve 4 is threadedly connected with a pipe mouth cover 5, and the pipe mouth cover 5 can be installed and removed by rotating it, so as to discharge the liquid.

[0029] In this embodiment, a connecting plate 2 is glued to one side of the film bag 1, and a handle 3 is clamped on the connecting plate 2 to facilitate the hanging setting of the entire device. At the same time, the handle 3 can be disassembled after the device is used for easy recycling.

[0030] Working principle: When using the device, let the patient lie flat and then insert the probe into the outlet hole 11, the drainage tube 7 is inserted into the patient's intraocular conjunctival sac, and the patient's lacrimal duct is rinsed through the flushing hole 10. After the probe is taken out, the spring 901 end of the splint 902 is pressed again, so that the anti-slip strip 903 of the splint 902 is in close contact with the patient's skin, thereby ensuring the fixing effect of the drainage tube 7, and the excess liquid inside is sucked out through the drainage tube 7, and then the device is hung as a whole to the patient's side through the handle 3 to avoid accidental contact with the patient. When the drainage tube 7 is blocked, the external thread 701 can be removed from the interface thread 601 by rotating the connector 6, and it can be replaced or unblocked. The liquid can be discharged and collected by opening the drain valve 4. The pipe mouth cover 5 can prevent bacteria from entering and avoid the drain valve 4 from being opened by mistake. After the use of the device is completed, the handle 3 can be disassembled as a whole and processed separately, which is conducive to recycling and reuse after processing.
