Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a disposable fluorescein sodium staining reagent strip. Background Art

[0002] There are many clinical patients in ophthalmology. Corneal fluorescein sodium staining is one of the commonly used detection methods in ophthalmology. In existing clinical practice, although there are separately packaged fluorescein sodium staining test strips, there is no directly prepared staining reagent.

[0003] The applicant found that there are at least the following technical problems in the existing technology: Before each use, medical staff need to separately prepare the staining reagent. After the staining reagent is prepared, the test strip and the reagent need to be fused, and the operation process is relatively cumbersome, increasing the workload of medical staff and causing inconvenience in use. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a disposable fluorescein sodium staining reagent strip to solve the technical problem that the operation process of the fluorescein sodium staining test strip before use in the existing technology is relatively cumbersome, increasing the workload of medical staff. The preferred technical solutions provided by the utility model can produce many technical effects, which will be elaborated below.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

[0006] A disposable fluorescein sodium staining reagent strip includes an outer layer unit, a film unit, a partition unit, a test strip and a staining reagent. The film unit is arranged inside the outer layer unit and divides the interior of the outer layer unit into a first cavity and a second cavity. The staining reagent is arranged in the first cavity. The partition unit is arranged inside the second cavity and divides the second cavity into a first space and a second space. The test strip includes a main body part and a staining part connected to each other. The main body part is located inside the second space, and the staining part passes through the partition unit and enters the first space.

[0007] Preferably, the outer layer unit is a waterproof wrapping paper.

[0008] Preferably, an easy tear opening is arranged at one end of the outer layer unit away from the staining reagent.

[0009] Preferably, the film unit is a film that is easy to rupture.

[0010] Preferably, an opening for the test strip to pass through is arranged in the middle of the partition unit.

[0011] Preferably, the partition unit is in a funnel shape.

[0012] Preferably, the staining reagent is 0.9% sodium chloride injection solution.

[0013] Preferably, a printing layer is provided on the back surface of the outer layer unit.

[0014] Preferably, the partition unit is waterproof paper.

[0015] The beneficial effects of the present utility model are as follows: When not in use, the film unit can prevent the staining reagent inside the first cavity from flowing into the second cavity. The film unit plays a role similar to wet-dry separation between the first cavity and the second cavity. The inside of the first cavity is a wet area, and the inside of the second cavity is a dry area.

[0016] When in use, press the outer layer unit corresponding to the first cavity forcefully. At this time, without affecting the overall structure of the outer layer unit, the film unit can be squeezed and broken. The staining reagent inside the first cavity can flow into the first space where the staining part is located. The staining reagent and the staining part of the test strip are fused inside the first space, so that the staining part of the test strip is wetted by the staining reagent. Since the set capacity of the staining reagent is not much, and the partition unit can isolate the first space to a certain extent, the staining reagent will not flow into the second space. After the staining part is in full contact with the staining reagent, the outer layer unit can be torn at the other end of the outer layer unit. At this time, the main body of the test strip is located at the torn opening, and medical staff can smoothly take out the test strip for subsequent actual detection.

[0017] Medical staff only need to first squeeze and break the film unit to fuse the test strip with the staining reagent, then tear the disposable outer layer unit and directly take out the wetted test strip, and then they can perform tests on patients. The operation process is more convenient, effectively saving department resources and providing convenience for clinical medical work. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] Refer to

[0029] Figure 1 the present utility model provides a disposable fluorescein sodium staining reagent strip, including an outer layer unit 1, a film unit 2, a partition unit 3, a test strip 4 and a staining reagent;

[0030] The outer layer unit 1 is located on the outermost layer, equivalent to the outer packaging, and a cavity can be formed inside the outer layer unit 1;

[0031] ​The thin film unit 2 is arranged inside the outer layer unit 1 and divides the interior of the outer layer unit 1 to form a first cavity 5 and a second cavity 6. The staining reagent is arranged in the first cavity 5, and the capacity of the staining reagent can preferably be 1 milliliter. Since the capacity of the staining reagent is not too much, the volume of the first cavity 5 can be adjusted according to the capacity of the staining reagent, so as to determine the actual setting position of the thin film unit 2;

[0032] The partition unit 3 is arranged inside the second cavity 6 and divides the second cavity 6 to form a first space 61 and a second space 62;

[0033] The test strip 4 includes a connected main body part 41 and a staining part 42. The main body part 41 is located inside the second space 62, and the staining part 42 passes through the partition unit 3 and enters the first space 61.

[0034] In this embodiment, the thin film unit 2 is preferably a thin film that is easy to break;

[0035] When not in use, the thin film unit 2 can block the staining reagent inside the first cavity 5 from flowing into the second cavity 6. The thin film unit 2 plays a role similar to wet-dry separation between the first cavity 5 and the second cavity 6. The inside of the first cavity 5 is a wet area, and the inside of the second cavity 6 is a dry area;

[0036] When in use, press the outer layer unit 1 corresponding to the first cavity 5 forcefully. At this time, without affecting the overall structure of the outer layer unit 1, the thin film unit 2 can be squeezed and broken. The staining reagent inside the first cavity 5 can flow into the first space 61 where the staining part 42 is located. The staining reagent and the staining part 42 of the test strip 4 are fused inside the first space 61, so that the staining part 42 of the test strip 4 is wetted by the staining reagent. Since the set capacity of the staining reagent is not much, and the partition unit 3 can isolate the first space 61 to a certain extent, the staining reagent will not flow into the second space 62. After the staining part 42 is in full contact with the staining reagent, the outer layer unit 1 can be torn at the other end of the outer layer unit 1. At this time, the main body part 41 of the test strip 4 is located at the torn opening, and medical staff can smoothly take out the test strip 4 for subsequent actual detection.

[0037] Medical staff only need to first squeeze and break the thin film unit 2 to fuse the test strip 4 with the staining reagent, then tear the disposable outer layer unit 1 and directly take out the wetted test strip 4, and then they can perform tests on patients. The operation process is more convenient, effectively saving department resources and providing convenience for clinical medical work.

[0038] As an optional implementation manner, the outer layer unit 1 is preferably a waterproof wrapping paper. With such a setting, when the reagent strip is not in use, the staining reagent can be isolated inside the first cavity 5 and does not come into contact with other structures.

[0039] As an alternative implementation, a tear-open opening 11 is provided at one end of the outer unit 1 away from the staining reagent. With this arrangement, it is easier for medical staff to tear open the outer unit 1, which is more labor-saving and time-saving, providing more convenience for medical staff.

[0040] As an alternative implementation, an opening through which the test strip 4 can pass is provided in the middle of the partition unit 3. The opening facilitates the operator to extract the test strip 4. Except for the opening position, the partition unit 3 can form a good isolation between the first space 61 and the second space 62.

[0041] As an alternative implementation, the partition unit 3 is funnel-shaped. The funnel shape can reasonably optimize the internal space of the first space 61, making it easier for the staining reagent and the staining part 42 to be fully integrated.

[0042] As an alternative implementation, the staining reagent is 0.9% sodium chloride injection. With this arrangement, the standard for preparing the staining reagent can be unified and standardized, better meeting the regulatory requirements of the diagnosis and treatment guidelines.

[0043] As an alternative implementation, a printing layer is provided on the back of the outer unit 1. The method of using the disposable fluorescein sodium staining reagent strip can be printed on the printing layer, facilitating medical staff to learn and use.

[0044] As an alternative implementation, the partition unit 3 is made of waterproof paper. With this arrangement, the staining reagent can be isolated as much as possible inside the first space 61 and does not enter the inside of the second space 62.

[0045] The above are only the specific implementation manners of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model can easily think of changes or substitutions, which should all be covered within the protection scope of the present utility model. Therefore, the protection scope of the present utility model shall be subject to the protection scope of the claims.
