Description

Technical Field

[0001] The utility model belongs to the technical field of teaching models, and particularly relates to an interactive infusion model for teaching. Background Art

[0002] With the continuous advancement of medical technology and the increasing emphasis on nursing education, clinical practice teaching occupies a pivotal position in nursing education. As a common clinical medical method, intravenous injection easily achieves the therapeutic concentration of drugs and can maintain the constant concentration required for efficacy. Through intravenous injection, drugs can quickly take effect. Therefore, in nursing, the ability to skillfully insert needles into patients is a basic skill that medical staff must possess. In nursing teaching, model arm models are often used for intravenous injection practice.

[0003] Traditional arm infusion models usually use materials such as silicone, latex, and mixed glue to simulate muscles, skin, and blood vessels on the back of the hand. They are made into a single arm for intravenous infusion teaching. When in use, students can use the model for repeated practice. However, most existing intravenous infusion arm models are large in size and complex in structure. They interfere greatly during needle training and are not convenient for medical staff to learn and use. At the same time, the existing intravenous infusion arm model is a fully enclosed structure. Therefore, the liquid injected after puncture cannot be effectively discharged. Therefore, after multiple practices, a large amount of liquid accumulates in the model, affecting later use. Moreover, when using the existing intravenous infusion arm model, the accuracy of the needle is judged only by the medical staff's touch and the fluid outflow from the simulated blood vessels in the model. The medical staff cannot understand the specific situation of the needle in a timely manner, the interactivity is poor, and it is not convenient for medical staff to use in training. Therefore, it is particularly important to design an interactive infusion model for clinical nursing teaching that is efficient, safe, and highly interactive.

[0004] Based on this, the present invention proposes an interactive infusion model for teaching to solve the problems existing in the above-mentioned prior art. Utility Model Content

[0043] Please see the attached Figure 1 To the attached Figure 5 , the utility model provides a technical solution:

[0044] An interactive infusion model for teaching, comprising an arm model 1, a model base 2, and a puncture needle 3; wherein:

[0045] The arm model 1 is a human arm model made of silicone material to simulate the skin of the human arm and enhance the authenticity of the arm model 1. A medical silicone hose 6 is installed in the arm model 1. It has the characteristics of high transparency and good elasticity and can well simulate human veins.

[0046] The model base 2 is installed at the bottom of the upper arm end of the arm model 1 and is rotatably connected to the arm model 1. It is used to fix the arm model 1 by simulating the human posture when in use, and is convenient for adjusting the inclination angle of the arm model 1 to simulate different postures of the human body during the infusion process;

[0047] The puncture needle 3 is used in cooperation with the puncture block 5 installed on the arm model 1, so that during the puncture training, the needle of the puncture needle 3 can be inserted into the simulated septum of the puncture block 5 at different positions of the arm model 1, the simulation training at different positions and postures is realized, and the comprehensive training of the puncture skills of medical personnel is realized.

[0048] It should be noted that in the embodiment, the positions of the human arm and the different blood vessels in the arm can be simulated by the arm model 1 and the silica gel hose 6 in the arm model 1, and the medical personnel can timely know the positions of the blood vessels at each puncture block 5 of the human arm during the puncture training, and the simulation and simulation effect is improved. Through the setting of the model seat 2, the inclination angle of the arm model 1 can be adjusted during use to simulate different postures of the human body during infusion. Through the setting of the puncture needle 3, the medical personnel can perform puncture simulation according to the injection and infusion requirements during puncture training, and the infusion tube and the syringe can be easily assembled during specific simulation, thereby improving the applicability and interactivity of the model during use.

[0049] As a preferred embodiment, as shown in Figure 1 and Figure 2 The puncture block 5 is provided with a plurality of puncture blocks 5, which are detachably installed at the designed needle entry points of the arm model 1, so that multi-position puncture experiments can be realized during use, and the puncture block 5 is made of the same material as the arm model 1.

[0050] It should be noted that in the embodiment, the positions of the needle entry points of the arm model 1 are set according to specific clinical requirements, and the puncture block 5 at different positions of the needle entry points is punctured by using the puncture needle 3 during use, so that the medical personnel can clearly and quickly know the positions of the blood vessels at the corresponding arm positions. At the same time, through the detachable installation of the puncture block 5, the puncture block 5 can be replaced according to the needs after multiple uses, the liquid leakage after puncture is reduced, and the training effect on the medical personnel can be effectively guaranteed.

[0051] As a preferred embodiment, as shown in Figure 1 and Figure 2 The arm model 1 is further provided with a liquid storage cavity 11, the liquid storage cavity 11 is in communication with one end of the silica gel hose 6, a volumetric flow meter 7 is arranged at the communication position of the liquid storage cavity 11 and the silica gel hose 6, and a sealing plug 8 is arranged at the discharge port of the liquid storage cavity 11.

[0052] It should be noted that in this embodiment, the provision of liquid reservoir 11 allows for the collection of liquid entering silicone hose 6, thus preventing the inability to effectively collect liquid flowing out of silicone hose 6 during use, which could affect the external environment, and preventing the infusion rate and flow rate from being accurately recorded. The provision of volumetric flowmeter 7 allows for the recording of the volume of liquid flowing into liquid reservoir 11 from silicone hose 6 over a given period of time, thereby recording the infusion or injection rate and flow rate, providing feedback and facilitating adjustments by medical personnel.

[0053] As a preferred embodiment, Figure 1 、 Figure 2 and Figure 5 As shown, the silicone hose 6 is detachably installed in the arm model 1, and the end of the silicone hose 6 away from the liquid storage chamber 11 passes through the arm model 1 and extends to the outside of the arm model 1, and is used in conjunction with the blood circulation simulation component.

[0054] It should be noted that in this embodiment, when used under normal conditions, a sealing cap is installed at the outer end of the silicone hose 6 to prevent leakage of the liquid in the silicone hose 6 during injection or infusion. At the same time, the detachable setting of the silicone hose 6 allows it to be replaced as needed after a period of use to avoid leakage caused by multiple punctures of the silicone hose 6, which may affect the training effect.

[0055] As a preferred embodiment, Figure 1 、 Figure 2 and Figure 5 As shown, the blood circulation simulation component includes a circulation pump 10 and two diversion hoses 101 arranged at both ends of the circulation pump 10. The other ends of the two diversion hoses 101 are respectively connected to the silicone hose 6 and the discharge outlet of the liquid storage chamber 11, so as to form a closed-loop structure that can simulate the blood circulation in the arm, and a blood injection bypass 102 is also provided on any of the diversion hoses 101.

[0056] It should be noted that in this embodiment, when simulating an infusion or injection under blood circulation, a diversion hose 101 can be installed at the outlet of the silicone hose 6 and the liquid storage chamber 11, respectively, to achieve communication between the silicone hose 6, the liquid storage chamber 11, the diversion hose 101, and the circulation pump 10. Under the control of the circulation pump 10, the blood circulation process is simulated, so that medical personnel can judge the accuracy of the needle position according to the return of the simulated blood during acupuncture training. At the same time, by simulating blood circulation, the simulated environment for medical personnel during training can be made more realistic, which is conducive to overcoming the psychological barriers of beginners. Simulated blood is injected into the diversion hose 101 through the blood injection bypass 102.

[0057] As a preferred embodiment, Figure 1and Figure 3 As shown, a fixing plate 21 is also provided on the model base 2, and the fixing plate 21 is connected to the arm model 1 through a rotating shaft 9, and an arc-shaped sliding groove 22 is also provided on the fixing plate 21. The sliding groove 22 is used in conjunction with the sliding rod 12 provided on the outer wall of the arm model 1, and an external thread is provided on the outer side of the sliding rod 12 to connect with the threaded sleeve 13.

[0058] It should be noted that in this embodiment, during the adjustment process, the inclination of the arm model 1 can be adjusted by adjusting the position of the slide rod 12 in the slide groove 22, and after the adjustment is completed, it can be locked by tightening the threaded sleeve 13 to simulate the different postures of the human body during the infusion process.

[0059] As a preferred embodiment, Figure 1 、 Figure 2 and Figure 4 As shown, the puncture needle 3 includes a syringe 31, a piston 32 and a puncture needle 33; wherein:

[0060] The syringe 31 is a cylindrical structure, and an injection branch 311 is provided on one side of the syringe 31 to communicate with the inner cavity of the syringe 31. A sealing cap 37 is also installed on the injection branch 311.

[0061] The piston 32 is movably mounted in the rear end cavity of the syringe 31;

[0062] The puncture needle 33 is installed at the front end of the syringe 31 and is used to simulate the puncture of the puncture block 5 .

[0063] It should be noted that in this embodiment, when in use, the puncture needle 33 is used to puncture the puncture block 5 and the silicone hose 6 to realize the acupuncture simulation and injection simulation process; at the same time, the setting of the injection branch tube 311 facilitates the connection of the infusion tube to realize the infusion simulation process.

[0064] As a preferred embodiment, Figure 4 As shown, a pressure sensor 34 is also provided at the front end of the syringe 31. The pressure sensor 34 is connected to the puncture needle 33 through a spring 35. When the puncture needle 33 is inserted into the diaphragm of the puncture block 5, pressure is generated. The pressure compresses the spring 35, and the spring 35 compresses the pressure sensor 34, thereby obtaining the needle insertion pressure. After the silicone hose 6 is punctured, the reading of the pressure sensor 34 suddenly decreases, so that medical personnel can clearly judge whether the needle is accurately inserted.

[0065] As a preferred embodiment, Figure 4 As shown, the front end of the syringe 31 is also provided with an extension tube 36 which is sleeve-connected with the puncture needle 33. The sleeve-connection sealing effect of the extension tube 36 and the puncture needle 33 prevents the injection liquid from leaking when the puncture needle 33 moves up and down.

[0066] As a preferred embodiment, as shown in Figure 1 The infusion model further comprises a display 4 arranged on the model base 2 and electrically connected with the pressure sensor 34 and the volumetric flow meter 7, for displaying the readings of the pressure sensor 34 and the volumetric flow meter 7, so as to facilitate the medical staff to judge whether the needle is accurately inserted during the simulation training, thereby improving the interactivity during the teaching and training process.

[0067] The interactive infusion model for teaching in use: first, according to the training and learning requirements, the position of the sliding rod 12 in the chute 22 is adjusted to adjust the inclination of the arm model 1, and after adjustment, the threaded sleeve 13 is tightened to lock, to simulate the different body posture of the human body during the infusion process; after the body posture adjustment is completed, according to the learning and training requirements, the puncture block 5 and the silica gel hose 6 at different positions are punctured by using the puncture needle 33 to perform the simulation puncture experiment; at the same time, in the puncture process, the readings of the pressure sensor 34 and the volumetric flow meter 7 on the display 4 are used to confirm whether the needle is accurately inserted, thereby improving the interactivity during the teaching and training process.

[0068] It should be noted that in the above description, the pressure sensor 34, the display 4 and the volumetric flow meter 7 are all relatively mature devices in the prior art, and the specific model can be selected according to the actual needs, which will not be repeated here.

[0069] The above is only a preferred embodiment of the present application, and is not intended to limit the scope of protection of the present application.
