Description

Technical Field

[0001] This utility model relates to the field of medical teaching equipment technology, and in particular to a lacrimal duct irrigation demonstration model. Background Technology

[0002] Lacrimal duct irrigation is a routine ophthalmic examination and treatment method. It can be used for preoperative ophthalmic preparation, diagnosis of lacrimal duct diseases, and promotion of drug absorption. It plays an important role in clarifying the diagnosis and improving patient symptoms.

[0003] Lacrimal duct irrigation is an essential skill for ophthalmology nurses. It requires a high level of expertise in the physiological and anatomical structure of the lacrimal duct, the use of irrigation needles, and the interpretation of irrigation results. The meticulous procedure demands a high degree of responsibility and focus from the operator. Therefore, lacrimal duct irrigation must be performed by professionally trained personnel.

[0004] However, current training methods for lacrimal duct irrigation are rather limited, only conducted during the actual procedure. This results in two problems: firstly, new nurses or interns struggle to retain the training effectively, leading to poor training outcomes; secondly, it may have adverse effects on patients. Utility Model Content

[0010] Furthermore, the upper lacrimal duct simulation tube, the lower lacrimal duct simulation tube, and the nasolacrimal duct simulation tube are all fixed to the lacrimal duct model plate by an adhesive layer.

CONCRETE IMPLEMENTATION

[0024] The utility model will be further described in combination with the drawings.

[0025] Please see Figs. 1-3 As shown, a lacrimal duct irrigation demonstration model includes a lacrimal duct model plate 1 and a lacrimal duct simulation pipeline 2 disposed on the lacrimal duct model plate 1.

[0026] The lacrimal duct model plate 1 is a plate with a lacrimal duct pattern. The real lacrimal duct includes the connected upper lacrimal duct, lower lacrimal duct and nasolacrimal duct. The connection between the upper lacrimal duct and the lower lacrimal duct is the common lacrimal duct.

[0027] In this embodiment, for example, the lacrimal duct model plate 1 is a PVC (polyvinyl chloride) plate.

[0028] The lacrimal duct simulation tube 2 includes an upper lacrimal duct simulation tube 3, a lower lacrimal duct simulation tube 4, and a nasolacrimal duct simulation tube 5 connected by a three-way connector 6. Each of the upper lacrimal duct simulation tube 3, the lower lacrimal duct simulation tube 4, and the nasolacrimal duct simulation tube 5 is equipped with a catheter clamp 7, which can control the opening and closing of the corresponding simulation tube. The lacrimal duct simulation tube 2 is fixed on the lacrimal duct model plate 1, and the positions of the upper lacrimal duct simulation tube 3, the lower lacrimal duct simulation tube 4, and the nasolacrimal duct simulation tube 5 correspond one-to-one with the positions of the upper lacrimal duct, the lower lacrimal duct, and the nasolacrimal duct in the lacrimal duct pattern on the lacrimal duct model plate 1.

[0029] In this embodiment, for example, the upper lacrimal duct simulation tube 3, the lower lacrimal duct simulation tube 4, and the nasolacrimal duct simulation tube 5 are all fixed to the lacrimal duct model plate 1 by an adhesive layer (e.g., glass glue), and the catheter clamp 7 is a Robert clamp.

[0030] In the above technical solution, the end of the upper lacrimal duct simulation tube 3 and the lower lacrimal duct simulation tube 4 furthest from the three-way connector 6 is its needle inlet. The irrigation simulation fluid (generally red liquid) is injected through the needle inlet of the upper lacrimal duct simulation tube 3 or the lower lacrimal duct simulation tube 4 to carry out lacrimal duct irrigation demonstration training.

[0031] More specifically, the lacrimal duct irrigation demonstration and training process is as follows:

[0032] Close the catheter clamp 7 on the upper lacrimal duct simulation tube 3, inject the irrigation simulation fluid from the needle inlet (upper lacrimal punctum) of the upper lacrimal duct simulation tube 3, and the irrigation simulation fluid flows out from the needle inlet (upper lacrimal punctum) of the upper lacrimal duct simulation tube 3. At this time, the upper lacrimal duct obstruction phenomenon is simulated.

[0033] Close the catheter clamp 7 on the lower lacrimal duct simulation tube 4, inject the irrigation simulation fluid from the needle inlet (lower lacrimal punctum) of the lower lacrimal duct simulation tube 4, and the irrigation simulation fluid flows out from the needle inlet (lower lacrimal punctum) of the lower lacrimal duct simulation tube 4. At this time, the lower lacrimal duct obstruction phenomenon is simulated.

[0034] Close the catheter clamp 7 on the nasolacrimal duct simulation tube 5, inject the irrigation simulation liquid from the needle insertion end (the upper punctum) of the upper lacrimal passage simulation tube 3, the irrigation simulation liquid flows out from the needle insertion end (the lower punctum) of the lower lacrimal passage simulation tube 4, inject the irrigation simulation liquid from the needle insertion end (the lower punctum) of the lower lacrimal passage simulation tube 4, the irrigation simulation liquid flows out from the needle insertion end (the upper punctum) of the upper lacrimal passage simulation tube 3, at this time, the phenomenon of the common canaliculus or the nasolacrimal duct obstruction is simulated.

[0035] As preferred, the upper lacrimal passage simulation tube 3, the lower lacrimal passage simulation tube 4 and the nasolacrimal duct simulation tube 5 are all transparent tubes, so as to observe the flow process of the irrigation simulation liquid in the lacrimal passage simulation pipeline 2.

[0036] In addition, in order to make the lacrimal passage simulation pipeline 2 closer to the real lacrimal passage, the pipe diameters of the upper lacrimal passage simulation tube 3 and the lower lacrimal passage simulation tube 4 are the same, and the pipe diameters of the two are both smaller than the pipe diameter of the nasolacrimal duct simulation tube 5.

[0037] As preferred, the irrigation tip 8 is further included, the irrigation tip 8 is a tube, one end of the irrigation tip 8 is provided with a rubber sealing plug 9, and the other end is provided with a connector for detachably connecting the irrigation tip 8 to the needle insertion end of the upper lacrimal passage simulation tube 3 or the lower lacrimal passage simulation tube 4.

[0038] In the embodiment, the connector of the irrigation tip 8 is a plug connector, that is, the irrigation tip 8 is connected to the needle insertion end of the upper lacrimal passage simulation tube 3 or the lower lacrimal passage simulation tube 4 in the form of plugging.

[0039] In the above technical solution, the lacrimal passage irrigation needle is punctured into the irrigation tip 8 through the rubber sealing plug 9 arranged in the irrigation tip 8, and then the irrigation simulation liquid can be injected into the corresponding simulation tube. Due to the sealing effect of the rubber sealing plug 9, the irrigation simulation liquid can flow better in the lacrimal passage simulation pipeline 2, and the lacrimal passage irrigation needle punctures the rubber sealing plug 9 close to the puncture of the human eye structure, thereby achieving a more realistic simulation effect.

[0040] Of course, the above is only the preferred embodiment of the present application, and does not limit the use range of the present application, therefore, any equivalent changes made on the principle of the present application shall be included in the protection scope of the present application.
