Description

Technical Field

[0001] The present application relates to the technical field of medical devices, and in particular to an intraocular fluid collector. Background Art

[0002] Viruses are one of the common pathogens of intraocular infection. Testing intraocular fluid viral nucleic acid for patients suspected of intraocular viral infection has become an important means to clarify the cause. In addition, being able to test intraocular fluid viral nucleic acid for patients diagnosed with intraocular viral infection is of great significance for adjusting the patient's subsequent treatment plan, determining the treatment endpoint, and predicting the treatment effect.

[0003] There is currently no dedicated intraocular fluid collector on the market. Based on this, this application proposes an intraocular fluid collector. Utility Model Content

[0004] In order to collect ocular fluid, the present application provides an intraocular fluid collector.

[0005] The present application provides an intraocular fluid collector, which adopts the following technical solution:

[0006] An intraocular fluid collector comprises a puncture needle and a capillary tube, wherein the puncture needle and the capillary tube are connected.

[0007] Furthermore, an automatic stop filter element is arranged in the capillary tube.

[0008] Furthermore, the intraocular fluid collector also includes a push rod, which is located on the side of the capillary away from the puncture needle, and the push rod can be slidably connected to the inner wall of the capillary along the length direction of the capillary.

[0009] Furthermore, a stop block is fixedly connected to one end of the push rod away from the puncture needle, and the size of the stop block is larger than the size of the push rod along the length direction perpendicular to the push rod.

[0010] Furthermore, the puncture needle is connected to the capillary tube via a Luer connector.

[0011] In summary, the beneficial technical effects of this application are:

[0012] The arrangement of the puncture needle and the capillary tube allows the staff to insert the puncture needle into the anterior chamber. Under the pressure of the intraocular fluid, the intraocular fluid will enter the capillary tube through the puncture needle to complete the collection of the aqueous humor or vitreous humor in the eye, that is, to achieve the purpose of collecting the intraocular fluid;

[0013] The setting of the automatic stop filter element allows the liquid in the capillary to stop automatically when the amount reaches a certain level, thereby achieving quantitative collection of intraocular fluid. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] The technical solution of the present application will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present application.

[0017] Intraocular fluid is a general term for the fluid inside the eyeball, which mainly includes aqueous humor and vitreous humor.

[0018] The present application embodiment discloses an intraocular fluid collector. Figure 1 The intraocular fluid collector includes a puncture needle 1 and a capillary 2.

[0019] The puncture needle 1 can be a 25G injection needle or an injection needle with a finer needle tip. In this embodiment, a 25G injection needle is used. One end of the capillary tube 2 is connected to the end of the puncture needle 1 away from the needle tip through a Luer connector 3. The Luer connector 3 is a Luer connector.

[0020] During use, the staff punctures the anterior chamber with the needle of the puncture needle 1 to collect aqueous humor or vitreous humor. When the needle of the puncture needle 1 enters the anterior chamber, under the pressure of the intraocular fluid, the intraocular fluid will be injected into the capillary 2 through the puncture needle 1, thereby collecting the intraocular fluid.

[0021] In order to facilitate the staff to collect the intraocular fluid quantitatively and avoid the situation of taking too much or too little intraocular fluid, an automatic stop filter element 4 is provided in the capillary 2, and the automatic stop filter element 4 is spaced apart from the Luer head connector 3. The distance between the automatic stop filter element 4 and the needle head of the puncture needle 1 is the amount of intraocular fluid sucked. In this embodiment, the automatic stop filter element 4 adopts a water-permeable closed filter element.

[0022] In order to prevent the automatic stop filter element 4 from being easily moved along the capillary tube 2 after being installed in place, the automatic stop filter element 4 and the capillary tube are interference fit.

[0023] In order to facilitate the staff to take out the intraocular fluid in the capillary 2, the intraocular fluid collector also includes a push rod 5, which is located on the side of the capillary 2 away from the puncture needle 1, and the push rod 5 can be slidably connected to the inner wall of the capillary 2 along the length direction of the capillary 2, so that the staff can insert the push rod 5 into the capillary 2, and then push the push rod 5 to automatically stop the filter element 4 to push out the intraocular fluid in the capillary 2.

[0024] In order to facilitate the staff to insert the push rod 5 into the capillary 2, the push rod 5 and the capillary 2 are clearance-matched.

[0025] In order to facilitate the staff to push and take the push rod 5, and to prevent the push rod 5 from falling out of the capillary 2, a stop block 51 is fixedly connected to the end of the push rod 5 away from the puncture needle 1. Along the direction perpendicular to the length of the push rod 5, the size of the stop block 51 is larger than the size of the push rod 5, so that the stop block 51 protrudes from the push rod 5, so that the staff can hold the push rod 5.

[0026] The implementation principle of a bed sheet installation structure of the embodiment of the present application is as follows: after the staff inserts the puncture needle 1 into the anterior chamber, under the pressure of the intraocular fluid, the intraocular fluid will enter the capillary 2 through the puncture needle 1 and stop flowing at the position of the automatic stop filter 4, thereby completing the quantitative collection of the intraocular fluid;

[0027] When the staff needs to take out the intraocular fluid in the collector, they insert the push rod 5 into the capillary 2 and push the push rod 5 so that the push rod 5 drives the automatic stop filter element 4 to push the intraocular fluid out of the puncture needle 1.

[0028] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
