[0022] The present invention will be further described below with reference to specific embodiments, but the scope of protection of the present invention is not limited thereto.
[0023] Example 1 refer to Figure 1 and Figure 2Example 1 provides a medical visual teaching demonstration system, including: a comprehensive nursing teaching mannequin 1, a first display terminal 2, a visual clinical intubation device 3, a second display terminal 4, a third display terminal, and a manual technique imaging display terminal 5.
[0024] The comprehensive nursing teaching manipulative 1 has an internal cavity 14 for simulating the body cavity of a human, the internal cavity 14 has an exposed opening, and a position recognition sensor 11 is set at a standard position of the internal cavity 14.
[0025] The internal cavity 14 is used to simulate internal anatomical structures, such as the oral cavity, nasal cavity, epiglottis, trachea, bronchi, esophagus, stomach, arteries, etc. The internal cavity 14 is made of silicone, for example, and can be red to simulate the color of real human body cavities.
[0026] The outer skin 12 encloses the inner cavity tube 14. The color of the outer skin 12 is, for example, yellow, to simulate the color of human skin. The material of the outer skin 12 is, for example, silicone.
[0027] The bracket 13 connects the outer skin 12 and the inner cavity tube 14 to enable the installation and fixation of the inner cavity tube 14, and supports the outer skin 12 to keep the outer skin 12 in a fixed shape. The bracket 13 is made of, for example, rigid plastic.
[0028] according to Figure 1 From the current perspective, the standard positions from right to left are the nasopharynx, glottis, first esophageal constriction, and cardia.
[0029] The position recognition sensor 11 is a photoelectric sensor, and a light-emitting element is provided at the insertion end of the visual clinical cannula 3. This light-emitting element is specifically an LED light.
[0030] refer to Figure 2 The position recognition sensor 11 is fixed to the circuit board 16, which in turn is fixed to the fixture 15. A battery (not shown) is mounted on the circuit board 16 for power supply. The fixture 15 is a rigid short tube with an elliptical cross-section, used to fix and support the circuit board 16. A mounting hole H is formed at the target location of the internal cavity tube 14.
[0031] When assembling the position recognition sensor 11 and the internal cavity tube 14, insert the fixing member 15 into the internal cavity tube 14 along the mounting hole H, and then fix the fixing member 15 to the internal cavity tube 14.
[0032] The fastener 15 is, for example, glued to the inner wall of the inner cavity tube 14. Alternatively, a threaded hole (not shown) can be made in the fastener 15, and a screw can be inserted through the inner cavity tube 14 and screwed into the threaded hole to install the fastener 15.
[0033] In this embodiment, the cross-section of the fastener 15 is elliptical, which facilitates the insertion of the fastener 15 from the mounting hole H into the internal cavity tube 14.
[0034] Continue to refer to Figure 3 Additionally, several fasteners 15 surround the internal cavity tube 14. Mounting holes H are formed in the internal cavity tube 14. A position recognition sensor 11 is fixed to a circuit board 16, which is fixed to the inner side of the fasteners 15. The circuit board 16 and the position recognition sensor 11 are positioned opposite to the mounting holes H. The fasteners 15 and the internal cavity tube 14 are fixedly connected by adhesive.
[0035] A first camera 31 is provided at the insertion end of the visualization clinical cannula 3. The first camera 31 is connected to the second display terminal 4 via a signal line 32. The first camera 31 is used to acquire real-time images of the internal lumen 14, and the second display terminal 4 is used to display the real-time images acquired by the first camera 31.
[0036] Visualized clinical intubation 3 includes visualized airway intubation, visualized urinary catheterization, visualized gastric tube, visualized suction tube, visualized enema tube, or other visualized endoscopes.
[0037] In this embodiment, the signal line 32 is threaded through the tube body of the visualization clinical cannula 3.
[0038] The position recognition sensor 11 is used to identify whether the insertion end of the visualized clinical cannula 3 is in the standard position.
[0039] When the insertion end of the visual clinical cannula 3 is close to the standard position, the light-emitting element at the insertion end of the visual clinical cannula 3 illuminates the position recognition sensor 11. When the insertion end of the visual clinical cannula 3 is far from the standard position, the ambient light around the position recognition sensor 11 is darker. The circuit board 16 processes the data on the light intensity of the position recognition sensor 11 to determine whether the insertion end of the visual clinical cannula 3 is near the target position.
[0040] The criteria for determining whether the insertion tip of the visualized clinical cannula 3 is in the standard position can be determined using experimental methods known in the art. For example, the appropriate light intensity or the range of light intensity variation can be experimentally determined as the criterion.
[0041] Specifically, the location identification sensor 11 is an infrared sensor, which is set in pairs. One emits infrared light and the other receives infrared light. When an object passes by, it will block the light, thereby detecting the passage of the object.
[0042] The first display terminal 2 is wirelessly connected to the position recognition sensor 11. The first display terminal 2 is used to display teaching information at the standard position when the insertion end of the visualized clinical cannula 3 is in the standard position.
[0043] The teaching information at the standard location includes at least one of the following: location information of the standard location, standard image, and text description.
[0044] The first display terminal 2 is also configured to be able to play teaching information at the standard location via voice.
[0045] The manual technique capture display terminal 5 has a second camera 51 and a display screen 52; the position and / or orientation of the second camera 51 can be manually adjusted, the second camera 51 is used to capture the hand operations of the intubation operator, and the display screen 52 is used to display the images captured by the second camera 51. The manual technique capture display terminal 5 is also connected to a third display terminal, which is used to display teaching information at a standard position, real-time images of the internal lumen 14, and the manual techniques captured by the second camera 51 on the same screen.
[0046] The third display terminal is a large teaching screen, which allows students to watch the teacher's explanation while seated.
[0047] The manual shooting display terminal 5 is equipped with buttons 53, which can be used for function settings. For example: zoom in, zoom out, freeze the current image, rotate the second camera 51, lock the focus of the second camera 51, turn the lights on / off, record video, take photos, etc.
[0048] The technique-capturing display terminal 5 captures the teacher's technique while simultaneously displaying the captured image on its own screen 52. This allows the teacher to adjust the position and / or orientation of the second camera 51, enabling students to view the teacher's technique from the optimal angle.
[0049] refer to Figure 1 The second camera 51 shoots from above and can rotate and bend freely 360° through a universal joint (not shown).
[0050] Example 2 Except for the following features, Embodiment 2 is the same as Embodiment 1: the first display terminal 2 and the second display terminal 4 are implemented by one display terminal.
[0051] That is, a single display terminal is wired to the visual clinical cannulation 3 and wirelessly connected to the position recognition sensor 11.
[0052] Example 3 Example 3 uses the medical visual teaching demonstration system of Example 1 as the teacher system, and omits the third display terminal and the manual shooting display terminal 5 of the medical visual teaching demonstration system of Example 1 to use it as the student system.
[0053] In this way, students can practice simultaneously with the teacher's explanation. Students can not only observe the real-time images acquired by the Visual Clinical Intubation 3, but also learn the corresponding teaching information when the Visual Clinical Intubation 3 is inserted into the target position. They can also adjust their own operation techniques by referring to the teacher's operation techniques, thereby improving the teaching effect.
[0054] Example 4 Except for the following features, Embodiment 4 is the same as Embodiment 1: the third display terminal and the manual shooting display terminal are omitted.
[0055] When in use, students watch the teacher operate the equipment.
[0056] Example 5 Except for the following features, Embodiment 5 is the same as Embodiment 3: The student system includes a technique shooting display terminal 5, which is used to shoot the student's technique and transmit the image to a third display terminal 6 via WiFi. The image is displayed on the same screen as the teacher's technique to achieve the effect of comparative teaching, or multiple student operation screens are displayed on the same screen. The teacher can view the operation screen of any student and make comments without leaving the podium.
[0057] Example 6 Except for the following features, Embodiment 6 is the same as Embodiment 1: the position recognition sensor 11 is a photoelectric sensor, and no light-emitting element is provided at the insertion end of the visual clinical cannula 3. Ambient light shines through the silicone onto the photoelectric sensor. When the visual clinical cannula 3 passes by the position recognition sensor 11, it also blocks the ambient light, thereby causing a change in the sensor signal.
[0058] This invention is not limited to the above-described embodiments. Any modifications, improvements, or substitutions that can be conceived by those skilled in the art without departing from the essential content of this invention fall within the scope of this invention.
