[0001] The utility model relates to the field of arterial puncture, in particular to an arterial puncture training model device under ultrasound guidance. Background Art

[0002] Critically ill patients often require arterial cannulation for continuous invasive arterial blood pressure monitoring and frequent arterial blood gas analysis. Traditional blind palpation has long been the main method for radial artery cannulation, but in obese, edematous, and hypotensive patients, blind palpation leads to multiple attempts, and failed procedures can lead to hematoma and arterial vasospasm. These complications become more likely to occur as the number of puncture attempts increases.

[0003] Current studies have shown that radial artery cannulation with dynamic needle tip positioning under ultrasound guidance is the safest and most effective method and is widely used during surgery.

[0004] However, there is currently a lack of ultrasound-guided arterial puncture models. Therefore, it is very necessary to design an ultrasound-guided arterial puncture model that can help puncture operators quickly learn the arterial puncture position training, has good practical value, is widely used, can reduce puncture complications for operators, and shorten the learning curve of puncture operators. In view of this, the utility model provides an ultrasound-guided arterial puncture training model device. Summary of the invention

[0029] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model is further described in detail below through the accompanying drawings and embodiments. However, it should be understood that the specific embodiments described herein are only used to explain the utility model and are not used to limit the scope of the utility model. In addition, in the following description, the description of the known structure and technology is omitted to avoid unnecessary confusion of the concept of the utility model. Example 1

[0030] See also Figure 1-3 The ultrasound-guided arterial puncture training model device comprises an infusion set 1 and a model body 2, wherein the model body 2 is provided with a cavity, the model body 2 is filled with simulated tissue in the entire cavity, a horizontally arranged catheter 3 is arranged in the model body 2, both ends of the catheter 3 penetrate the model body 2 and extend to the outside of the model body 2, wherein one end of the catheter 3 is set to be closed, and the other end of the catheter 3 is connected to the infusion set 1.

[0031] As a further illustration of this embodiment, the infusion set 1 is connected to an infusion bottle 4, and the infusion bottle 4 is filled with red ink-physiological saline solution simulating human blood.

[0032] In this embodiment, the simulated tissue is tofu. Since tofu is a soft substance, easy to obtain, and cheap, it is very suitable for puncture.

[0033] In this embodiment, the infusion device 1 includes a needle 11, an infusion tube 12, a liquid storage cavity 13 and an infusion switch 14. One end of the infusion tube 12 is connected to the needle 11, the needle 11 is connected to the infusion bottle 4, and the liquid storage cavity 13 and the infusion switch 14 are installed on the infusion tube 12.

[0034] In this embodiment, the catheter 3 with one closed end is formed into a closed end by an on-off valve 6 or a vascular clamp.

[0035] In this embodiment, an opening and closing cover 21 is provided on the top of the model body 2. The model body 2 is made of a material that is easily penetrated and airtight. Existing boxed tofu can be directly used. The model body 2 can also be redesigned, first installing the conduit 3 in the model body 2, then sealing the two ends of the conduit 3, adding tofu to the model body 2, and after the tofu is in a stable state, closing it with the opening and closing cover 21, and finally the model body 2 can be put into use.

[0036] In this embodiment, the device requires an auxiliary imaging mechanism (not shown in the figure), which includes a detection component (not shown in the figure) and a display (not shown in the figure). One end of the detection component is connected to the model body 2, and one end of the detection component corresponds to the position of the infusion tube 12, and the other end of the detection component is connected to the display. The connection between the detection component and the model body 2 is used to detect and scan the position characteristics of the internal structure of the model body 2. The puncturist can intuitively observe the position information of the puncture needle 5 during the puncture process through the imaging mechanism, which facilitates the puncture needle 5 to be quickly and accurately placed in the catheter 3. Through this device, the puncturist holds the puncture needle 5 to practice pulse puncture and catheterization under ultrasound guidance, which lays a good operating foundation for the practitioner to be able to skillfully use the conventional ultrasonic puncture tools in current medicine.

[0037] Working principle of this embodiment: the model body 2 is a cavity that can carry simulated tissue. The model body 2 can directly adopt the existing boxed tofu, which simulates the tissue around the artery. Red ink-physiological saline simulates blood. The infusion set 1 is placed on the infusion stand to provide a certain pressure to simulate blood pressure and promote blood reflux. If boxed tofu is used, it is necessary to first penetrate the boxed tofu with a hollow puncture needle 5, then place a guide wire in the penetrated hole, and then remove the hollow puncture needle 5, pass the catheter 3 through the boxed tofu along the guide wire, so that both ends of the catheter 3 penetrate the model body 2 and extend to the outside of the model body 2. Then remove the guide wire, set one end of the catheter 3 to be closed, and the other end of the catheter 3 is connected to the infusion set 1. Then exhaust the air, loosen the vascular clamp, and fill the infusion tube 12 and the catheter 3 with liquid by adjusting the infusion switch 14. Then close one end of the catheter 3 with the vascular clamp again, and turn on the infusion switch 14. The puncture operator can perform direct puncture of the model through the puncture needle 5, which is convenient for the operator's in vitro operation training. When the "artery" is punctured, "blood reflux" can be seen in the arterial needle, which helps the puncturist to quickly learn the arterial puncture position, has good practical value and is widely used. Example 2

[0038] The difference from Example 1 is: Figure 4-7The catheters 3 are provided in multiple groups, and the multiple groups of catheters 3 are evenly arranged in an array in the model body 2. By providing multiple groups of catheters 3, the puncture operator can perform multiple experiments in one model body 2.
