Description

Technical Field

[0001] The utility model relates to the technical field of medical teaching aids, in particular to a subclavian vein puncture teaching aid that can be used for both ultrasound guidance and blind method. Background Art

[0002] Venipuncture is the most basic technical operation in clinical practice. Therefore, the practice of venipuncture is very important. To practice venipuncture, simulation teaching aids are needed. The existing subclavian vein puncture simulation teaching aids, such as the models disclosed in CN201838240U and CN109461358A, only simulate the skin, subcutaneous tissue, muscle and vascular tissue at the puncture site. During the operation, trainees cannot experience how to bypass the clavicle to explore the subclavian vein when encountering the clavicle on a real patient's body, nor can they experience the pulmonary structure under the subclavian vein and the operation skills to avoid pneumothorax. In addition, the above teaching aids also have the teaching function of ultrasound guidance. However, even when performing subclavian vein puncture and catheterization under ultrasound guidance, trainees can only understand the needle insertion direction and depth through ultrasound images, and cannot intuitively feel the whole process of the puncture needle body walking in the human body. The utility model provides a subclavian vein puncture teaching aid that can be used for both ultrasound guidance and blind method to solve the above problems. Summary of the Utility Model

[0003] The utility model provides a subclavian vein puncture teaching aid that can be used for both ultrasound guidance and blind method, which realizes the dual teaching functions of ultrasound guidance and blind puncture by using a transparent model body and an opaque blind operation film.

[0004] The technical solution adopted by the utility model to solve the above technical problems is as follows:

[0005] A subclavian vein puncture teaching aid that can be used for both ultrasound guidance and blind method includes a model body, a simulated skeleton, simulated circulatory blood vessels, a simulated lung and a blind operation film. The simulated skeleton is arranged in the model body. The simulated skeleton includes a clavicle and ribs. The simulated circulatory blood vessels include a subclavian vein and a subclavian artery. The in-vivo pipelines of the subclavian vein and the subclavian artery are located in the model body and are between the clavicle and the ribs. The simulated lung is arranged in the model body. The blind operation film is detachably connected to the model body.

[0006] Further, the model body is of a transparent structure, the blind operation film is an opaque film, and the blind operation film covers the surface of the model body.

[0007] Further, the simulated lung includes an in-vivo airbag and an airbag circulation pump. The in-vivo airbag is arranged in the model body and is below the ribs. The airbag circulation pump is arranged outside the model body and is connected to the in-vivo airbag.

[0008] Furthermore, the subclavian vein and the subclavian artery are independent closed loops. The external structures of the subclavian vein and the subclavian artery both include a circuit pipe and a circuit water pump. The circuit pipe is connected to the in-vivo pipeline to form a closed loop, and the circuit water pump is arranged in the closed loop.

[0009] Furthermore, red and blue liquids are respectively injected into the subclavian vein and the subclavian artery.

[0010] Furthermore, the pressurization mode of the circuit water pump of the subclavian vein is continuous non-pulsatile wave pressure water supply, and the pressurization mode of the circuit water pump of the subclavian artery is pulsatile pressure water supply.

[0011] Furthermore, the material of the model body is transparent silica gel, and the blind operation film is adhered to the model body.

[0012] The beneficial effects of the present utility model are as follows:

[0013] The model body made of a transparent material enables trainees to visually observe each anatomical structure during the initial learning stage, thereby enabling trainees to conduct preliminary exercises under visual conditions, improving the operation accuracy, and enabling trainees to form correct operation techniques at the initial stage of teaching. After getting familiar with the operation techniques, the model body is covered by the opaque blind operation film to conduct advanced teaching on blind puncture and ultrasound-guided puncture for trainees, enabling trainees to gradually master the correct puncture operation. Through the gradual teaching steps, trainees can conduct phased learning, with better teaching quality and higher learning efficiency.

[0014] The simulated lung is set and can simulate the breathing movement of the lung, enabling trainees to understand the lung structure during learning and truly simulate the complication of pneumothorax during puncture, which is beneficial for trainees to master the correct puncture method faster and understand the correct response operations in case of emergencies.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0018] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the specification. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0019] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "center", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation to the present invention.

[0020] As Figure 1 、 2 shown, when performing subclavian vein puncture, the needle needs to be close to the clavicle and look for the subclavian vein from below the clavicle, and the needle is inserted between the clavicle and the first rib. When puncturing, it should be avoided to puncture the lung. Therefore, during puncture teaching, novice trainees need to perform the puncture operation as correctly as possible to form a habit, so as to complete the learning quickly. A subclavian vein puncture teaching aid that can be used both with ultrasound guidance and blindly, provided by the present invention, includes a model main body 1, a simulated skeleton 2, a simulated circulatory blood vessel 3, a simulated lung 4, and a blind operation film 5. The simulated skeleton 2 is arranged in the model main body 1. The simulated skeleton 2 includes a clavicle 21 and a rib 22. The simulated circulatory blood vessel 3 includes a subclavian vein 31 and a subclavian artery 32. Both the subclavian vein 31 and the subclavian artery 32 include an in-vivo pipeline and an in-vitro structure. The in-vivo pipelines of the subclavian vein 31 and the subclavian artery 32 are located in the model main body 1 and are between the clavicle 21 and the rib 22. The simulated lung 4 is arranged in the model main body 1. The blind operation film 5 is detachably connected to the model main body 1.

[0021] As Figure 1 、 2As shown in the figure, in a specific embodiment of the present utility model, a model main body 1 made of transparent silica gel enables beginners to intuitively observe the collarbone, the first rib, the lungs, and the subclavian artery. When performing a puncture operation, it can better make the tip of the needle close to the collarbone and insert the needle through the gap between the collarbone and the first rib, while avoiding damaging the lungs and the subclavian artery. Thus, trainees can learn the correct and standardized operation techniques and form habits, which helps to complete the initial learning faster. After completing the initial learning, a blind operation film 5 made of an opaque film is covered on the surface of the model main body 1, so that the internal structure of the model main body 1 is completely blocked and trainees cannot see its internal anatomical structure. When the correct puncture operation has been mastered in the initial learning, blind puncture and ultrasound-guided puncture learning of trainees are carried out to complete advanced teaching; the above-mentioned phased learning enables trainees to complete the learning in a relatively short time and learn the correct and standardized operation techniques, improving the teaching efficiency and teaching quality. A body airbag 41 made of rubber material is used to simulate the lungs, and an airbag circulation pump 42 is used to control the body airbag 41 to perform cyclic inflation and deflation to simulate the breathing action of the lungs, so as to simulate the situation where the lung apex moves up and down with breathing during the puncture operation, increasing the realism during puncture and familiarizing with the structure and physiological actions of the lung structure. At the same time, it can also truly simulate the complication of pneumothorax during puncture, enabling trainees to understand the corresponding emergencies and take correct countermeasures. Through the above structure, this embodiment enables trainees to learn correctly faster, ensuring the teaching efficiency and teaching quality.

[0022] As Figure 1 , 2 shown in the figure, further, the simulated lungs 4 include a body airbag 41 and an airbag circulation pump 42. The body airbag 41 is arranged in the model main body 1 and is located below the rib 22 to simulate the lungs. The airbag circulation pump 42 is arranged outside the model main body 1 and is connected to the body airbag 41. The airbag circulation pump 42 makes the body airbag 41 expand and contract through automatic inflation and deflation to simulate the breathing action of the lungs, truly simulating the human body situation, making the teaching environment more in line with the real situation, and improving the teaching quality.

[0023] Preferably, the body airbag 41 is made of rubber material and is a disposable item, which can be replaced after being damaged.

[0024] As Figure 1 , 2 shown in the figure, further, the subclavian vein 31 and the subclavian artery 32 are independent closed loops. The external structures of the subclavian vein 31 and the subclavian artery 32 both include a circuit pipe and a circuit water pump. The circuit pipe is connected to the internal pipeline to form a closed loop, and the circuit water pump is arranged in the closed loop.

[0025] Furthermore, the subclavian vein 31 and the subclavian artery 32 are respectively injected with red and blue liquids to distinguish between the artery and the vein.

[0026] Furthermore, the pressurization mode of the circuit water pump of the subclavian vein 31 is continuous non-pulse pressure water supply, and the pressurization mode of the circuit water pump of the subclavian artery 32 is pulse pressure water supply, which respectively simulates arterial and venous blood flow.

[0027] Furthermore, the model body 1 is made of transparent silicone, and the internal structure can be clearly seen. The blind operation film 5 is adhered to the model body 1. After the blind operation film 5 is affixed, the internal structure of the model body 1 is blocked and cannot be seen visually. The operator can only perform blind operation based on experience, or operate under ultrasound guidance.

[0028] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims are included in the present invention, and any figure mark in the claims should not be regarded as limiting the claims involved.
