Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to the fields of gastric tube insertion and triple-lumen two-balloon tube insertion, and specifically refers to a simulator device applied to gastric tube and triple-lumen two-balloon tube insertion. Background Art

[0002] Gastric tube insertion and triple-lumen two-balloon tube insertion are important clinical operation skills, which are widely used in clinical diagnosis and treatment and perioperative management, and are also one of the 24 skills for the operation assessment of practicing physicians. However, the traditional training of gastric tube insertion and triple-lumen two-balloon tube insertion can usually only be carried out on ordinary molds. The existing molds can only train the operation steps and basic technical points, and there are many limitations. For example, after the gastric tube is inserted, the mold cannot draw out gastric juice, resulting in the inability to judge whether the gastric tube is actually inserted into the stomach; at the same time, the mold cannot simulate the auscultatory gurgling sound during injection, and the trainees can only confirm whether the gastric tube is in place and the corresponding precautions through oral description, which has a large gap with the actual clinical operation and cannot effectively simulate the operation and assessment in real situations. In addition, since the mold cannot simulate the pressure changes after the gastric balloon and esophageal balloon are inflated, the trainees cannot feel the hemostatic effect and the effectiveness of tube placement through actual operation. These problems make it difficult for the traditional training molds to meet the needs of clinical skills training, and the trainees may face greater challenges in actual operation.

[0003] Based on this, in view of the many deficiencies of the existing training molds for gastric tube and triple-lumen two-balloon tube insertion, which cannot meet the needs of clinical skills training, it is necessary to design an improved mold to overcome and solve the deficiencies of the current existing technologies. Summary of the Utility Model

[0009] A first pressure sensor, disposed at the lower part of the esophagus, for detecting the pressure on the esophagus after the gastric balloon and the esophageal balloon in the triple-lumen and double-balloon tube are inflated with gas; and

[0010] A second pressure sensor, disposed at the fundus of the stomach, for detecting the pressure on the stomach after the gastric balloon and the esophageal balloon in the triple-lumen and double-balloon tube are inflated with gas.

[0011] Preferably, the stomach is made of an elastic transparent material, and simulated gastric juice is infused therein through a gastric juice infusion port provided inside, and an external injection pipeline is connected.

[0012] Preferably, the simulated skin further includes an openable front skin, and the introduction position of the gastric tube can be observed by opening the front skin.

[0013] Preferably, the one-way valve is a detachable structure, and a detachable buckle is provided thereon. One end of the buckle is connected to the esophagus, and the other end is fixedly connected to the cardiac orifice.

[0015] Preferably, the simulated human device is further provided with an external display screen, and the external display screen is signal-connected to the first pressure sensor and the second pressure sensor for displaying the detected pressure change values of the gastric balloon and the esophageal balloon.

[0037] In order to more clearly describe the technical content of the present utility model, the following will be further described in conjunction with specific embodiments.

[0038] Before elaborating on the embodiments according to the present invention, it should be noted that, hereinafter, the terms "comprising", "including" or any other variants are intended to cover non-exclusive inclusion, such that a process, method, article or device comprising a series of elements not only includes these elements but also includes other elements not expressly listed, or elements inherent to such process, method, article or device.

[0039] Please refer to Figures 1 to 3 As shown, the humanoid device of the present invention applied to the intubation of gastric tubes and triple-lumen double-balloon tubes, wherein the humanoid device comprises:

[0040] A humanoid model, which is an upper-body human model including the nasal cavity part, oral cavity part, pharynx part, esophagus part and stomach 7, and the proportions of its various organs are consistent with the human organ structure, and a simulated skin is provided on the outer surface of the humanoid model;

[0041] A replaceable one-way valve 6 provided between the esophagus part and the cardiac orifice, which is designed as a valve. By squeezing the valve, the valve can be opened, and by closing the valve in the reverse direction, the reflux of simulated gastric juice into the esophagus part can be blocked, and it is used to control the flow direction of the simulated gastric juice;

[0042] A first pressure sensor 5a, which is arranged at the lower part of the esophagus part, and is used to detect the pressure on the esophagus part after the gastric balloon and esophageal balloon in the triple-lumen double-balloon tube are inflated with gas; and

[0043] A second pressure sensor 5b, which is arranged at the fundus of the stomach 7 (the fundus of the stomach mentioned here is one of the anatomical structures of the stomach 7, located on the left side of the cardiac orifice, in the shape of a dome, and is the upper expanded part of the stomach 7. It jointly constitutes the basic shape of the stomach 7 with the gastric body and pyloric part, mainly participates in food storage and digestive juice secretion, and is closely related to surrounding organs such as the esophagus part and the diaphragm), and is used to detect the pressure on the stomach 7 after the gastric balloon and esophageal balloon in the triple-lumen double-balloon tube are inflated with gas, so as to assist in evaluating the effectiveness of catheterization and hemostasis.

[0044] As a preferred embodiment of the present invention, the stomach 7 is made of elastic and transparent silica gel material, and simulated gastric juice is infused into it through a gastric juice infusion port 3 arranged inside. Usually, a normal amount of simulated gastric juice or gastric retention residues are injected; an injection pipeline is connected to the outside to simulate different clinical situations.

[0045] As a preferred embodiment of the present invention, the simulated skin includes an openable front skin 2. By opening the front skin 2, the accuracy of the insertion position of the gastric tube 9 can be evaluated.

[0046] As Figure 2 and 3 shown, Figure 2 and Figure 3To remove the simulated skin set on the outer surface of the model and the upper body shell on the basis of Figure 1 , so as to more clearly observe the installation positions and structural features of the one-way valve 6, the stomach 7, the first pressure sensor 5a, and the second pressure sensor 5b set inside the model. Figure 1 As shown in and

[0047] , as a preferred embodiment of the present utility model, the one-way valve 6 is a detachable structure, and a detachable buckle is provided thereon. One end of the buckle is connected to the esophageal part, and the other end is fixedly connected to the cardia. And after the gastric tube 9 is inserted into the simulation human device from the gastric tube insertion point 1, it enters the stomach 7 through the one-way valve 6, so as to draw out the simulated gastric juice. And by injecting air into the gastric tube 9 and auscultating the sound of air passing through water, the position of the gastric tube 9 can be determined. In practical applications, the one-way valve 6 adopted in this technical solution, because the detachable buckles designed thereon are respectively fixedly connected to the esophageal part and the cardia, this design can be replaced in time after the one-way valve 6 ages, avoiding replacing the entire simulation human device, thereby saving the use cost.

[0047] As Figures 4 to 6 and Figure 9 shown, as a preferred embodiment of the present utility model, a one-way valve blade 8 is further provided on the one-way valve 6, where Figure 7 and Figure 8 are respectively schematic diagrams of the structures on the upper and lower sides of the one-way valve blade 8. By setting the one-way valve blade 8, it can prevent the simulated gastric juice from flowing back into the esophagus or even flowing out of the body through the esophagus and nasal cavity, and at the same time ensure that the gastric tube 9 can successfully draw out the simulated gastric juice and complete the diagnosis of the sound of air passing through water after being inserted into the stomach 7.

[0048] As Figures 7 to 9 shown, as a preferred embodiment of the present utility model, the simulation human device is further provided with an external display screen 4, and the external display screen 4 is signal-connected to the first pressure sensor 5a and the second pressure sensor 5b for displaying the detected pressure change values of the gastric sac and the esophageal sac. Figure 7 and Figure 8 respectively are schematic diagrams of the structures on the upper and lower sides of the one-way valve blade 8. By setting the one-way valve blade 8, it can prevent the simulated gastric juice from flowing back into the esophagus or even flowing out of the body through the esophagus and nasal cavity, and at the same time ensure that the gastric tube 9 can successfully draw out the simulated gastric juice and complete the diagnosis of the sound of air passing through water after being inserted into the stomach 7.

[0049] As Figure 1 shown, as a preferred embodiment of the present utility model, the simulation human device is further provided with an external display screen 4, and the external display screen 4 is signal-connected to the first pressure sensor 5a and the second pressure sensor 5b for displaying the detected pressure change values of the gastric sac and the esophageal sac.

[0050] Adopting the simulation human device of the present utility model applied to the gastric tube and the three-lumen two-balloon tube placement technique can more realistically simulate the clinical operation process, help trainees master key skills, and improve the operation accuracy and safety. By setting designs such as replaceable one-way valves, transparent gastric materials, and pressure sensors, it can effectively simulate key steps such as drawing out simulated gastric juice, auscultating the sound of air passing through water, and monitoring the pressure changes of the gastric sac and the esophageal sac, thereby improving the operation skills and clinical response capabilities of trainees.

[0051] In this specification, the present utility model has been described with reference to its specific embodiments. However, it is obvious that various modifications and alterations can still be made without departing from the spirit and scope of the present utility model. Therefore, the specification and the drawings should be regarded as illustrative rather than restrictive.
