Description

Technical Field

[0001] The present application relates to the technical field of nasogastric feeding models, and in particular to an anti-dumping nasogastric feeding teaching model. Background Art

[0002] Nasogastric feeding is a procedure in which a gastric tube is artificially placed into the esophagus through the nasal cavity under special circumstances, and food is then injected into the body through the gastric tube to help patients who cannot swallow independently maintain normal nutrition and metabolism in their bodies.

[0003] Current models used for nasogastric feeding teaching are typically half-body shaped, allowing students to clearly observe the tube being inserted into the esophagus through the nasal cavity. However, when the existing teaching models are upright, they can easily become unbalanced and fall over, even to the ground, while the instructor is inserting the tube or performing the procedure, thus damaging the model. Utility Model Content

[0004] The utility model provides an anti-dumping nasogastric feeding teaching model, which has the advantage of not being easily dumped and fallen during use.

[0005] The purpose of this utility model is achieved through the following technical solutions:

[0006] An anti-dumping nasogastric feeding teaching model, comprising a model body and a fixing device;

[0007] The fixing device includes a chassis, a clip and an elastic member.

[0008] A sliding block is provided at the lower end of the clip, a sliding groove is provided at the upper end of the chassis, one end of the elastic member is fixed to the sliding groove wall, and the other end is fixed to the sliding block; there are two fixing devices, and the model body fixing clamp is arranged between the two clips.

[0009] Among them, fixing the model body with a fixing device can prevent the teacher from accidentally knocking over the model and causing it to break during the demonstration of nasogastric tube intubation.

[0010] Preferably, the nasogastric feeding teaching model also includes two connecting rods. A rotating column is provided at the upper end of the chassis. The two connecting rods are arranged in an X shape, and the middle part is rotatably connected to the rotating column. Both ends of the two connecting rods are respectively connected to the clips for transmission.

[0011] Among them, the advantage of connecting the two fixing devices through a connecting rod is that the user only needs to apply force to the clip on one side, and the clip on the other side will move in the opposite direction of the clip.

[0012] Preferably, the clip is provided with a sliding groove, and correspondingly, the upper end of the connecting rod is provided with a protrusion that is slidably adapted to the sliding groove.

[0013] Preferably, a notch is provided at the upper end of the clip.

[0014] Preferably, a transparent window is provided in the middle of the model body.

[0015] Compared with the prior art, the advantages or beneficial effects of the technical solution of this application include:

[0016] 1. Fix the model body with a fixing device and place it on the demonstration podium to prevent the teacher from accidentally knocking over the model and causing damage during the demonstration of gastric tube nasogastric feeding intubation.

[0017] 2. The model body and the fixing device are detachable. Users can selectively install the fixing device on the model body according to actual conditions. After use, it can also be stored separately to minimize the space occupied by the nasogastric feeding teaching model. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The following will describe the implementation methods of this application in detail with reference to the accompanying drawings and examples, so that the application can fully understand how technical means are used to solve technical problems and achieve corresponding technical effects, and implement them accordingly. The embodiments of this application and the various features therein can be combined with each other without conflict, and the resulting technical solutions are all within the scope of protection of this application.

[0022] It should be clear that the embodiments described below are only some of the embodiments of this application, rather than all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without making any creative work are within the scope of protection of this application. Example

[0023] Based on the above description, this embodiment provides the following additional explanations from a practical application perspective:

[0024] like Figure 1 and Figure 2As shown, an anti-dumping nasogastric feeding teaching model includes a model body 13, a connecting rod 6 and a fixing device;

[0025] The fixing device includes a chassis 11, a clip 1, and an elastic member 5. The lower end of the clip 1 is provided with a sliding block 3, and the upper end of the chassis 11 is provided with a sliding groove 4. One end of the elastic member 5 is fixed to the sliding groove wall, and the other end is fixed to the sliding block 3. There are two fixing devices, and the model body 13 is fixedly clamped between the two clips 1. There are two connecting rods 6. The upper end of the chassis 11 is provided with a rotating column 9. The two connecting rods 6 are arranged in an X shape, and the middle portion is rotationally connected to the rotating column 9. The two ends of the two connecting rods 6 are respectively connected to the clip 1. The clip 1 is provided with a sliding groove 2, and accordingly, the upper end of the connecting rod 6 is provided with a protrusion 14 that slides and adapts to the sliding groove 2.

[0026] How the fixture works:

[0027] like Figure 2 As shown, the fixing device is mainly used to fix the model body. When the model body needs to be clamped and fixed, the clip 1 can be pulled. Figure 2 For example, when the left clip 1 is pulled leftward, the angle between the two connecting rods 6 decreases (using the left side as a reference), pushing the right clip 1 to the right. At this point, the user simply places the model body between the two clips 1. When the user stops applying force to the clips 1, the elastic member (spring) rebounds, causing the left clip 1 to move rightward until it abuts against the model body 1, securing it in place.

[0028] like Figure 2 The upper end of the clip 1 is provided with a notch 10. The function of the notch 10 is to facilitate the staff to apply force with their fingers.

[0029] like Figure 1 As described above, a transparent window 12 is provided in the middle of the model body 13. Students can observe the human body structure inside the model body and the location of the gastric tube and nasogastric feeding tube through the transparent window 12, making the teaching image more vivid and easy for students to understand. Example

[0030] In order to facilitate the teaching task, the model body 13 can be split in half along the midline of the head to achieve a transparent anatomical surface, thereby making it easier for students to understand the entire process of nasogastric tube feeding of nutrient solution and making the teaching process smoother.
