Description

Technical Field

[0001] This utility model relates to the field of medical teaching equipment technology, and in particular to a rabbit ear vein injection simulation training device. Background Technology

[0002] Rabbits are important laboratory animals in medical experiments, often used in pharmacological and toxicological experiments. The marginal ear vein of rabbits is the preferred site for drug injection in these experiments. Therefore, rabbit marginal ear vein injection is a skill that every medical student and other experimenters must master.

[0003] Currently, most universities choose to use rabbits for experiments. However, cases of rabbits dying or becoming unusable due to improper handling, and students being accidentally injured by syringes, frequently occur. This increases teaching expenses and costs, poses risks to students, and violates the principles of animal protection, such as minimizing animal suffering. Therefore, it is necessary to provide students with thorough pre-experiment training to improve the success rate of operations, and to use rabbit marginal ear vein injection simulation training devices.

[0004] Some existing training devices use liquid to replace blood and silicone to replace blood vessels, which are highly realistic, but have defects. Repeated use may cause leakage, affecting storage and use. In addition, they do not provide enough protection for students, and there is a risk of the model piercing and injuring their fingers. Utility Model Content

[0005] The technical problem to be solved by this utility model embodiment is to provide a rabbit ear vein injection simulation training device, which can avoid leakage during training and improve the safety of intravenous injection simulation training.

[0006] This utility model discloses a rabbit ear vein injection simulation training device, comprising: a rabbit ear model, a syringe, and an indicator circuit. The rabbit ear model contains at least one ear vein model, which includes an insulating sleeve for simulating blood vessels and a conductive core for simulating blood. The conductive core is located within the inner ring of the insulating sleeve. A puncture-resistant layer is provided on one side of the rabbit ear model, and a conductive layer is provided between the puncture-resistant layer and the ear vein model. The indicator circuit includes a power supply, a first indicator and a second indicator electrically connected to one electrode of the power supply, and the first and second indicators are connected in parallel. The first indicator is electrically connected to the conductive core, and the second indicator is electrically connected to the conductive layer and to the syringe and the other electrode of the power supply.

[0007] Optionally, the syringe includes a syringe and a puncture needle connected to the syringe. The power supply is electrically connected to the puncture needle so that when the puncture needle punctures the conductive core, the circuit containing the first indicator is turned on, and when the puncture needle punctures the conductive layer, the circuit containing the second indicator is turned on simultaneously.

[0008] Optionally, the conductive core and the conductive layer are made of conductive silicone.

[0009] Optionally, the puncture-resistant layer is made of puncture-resistant fabric.

[0010] Optionally, the first indicator includes a first indicator light.

[0011] Optionally, the first indicator may further include a first horn connected in series with the first indicator light.

[0012] Optionally, the second indicator includes a second indicator light.

[0013] Optionally, the second indicator may also include a second horn connected in series with the second indicator light.

[0014] Optionally, the indicating circuit further includes a switch connected in series with one electrode of the power supply.

[0015] Optionally, the indicating circuit further includes a support, on which the first indicator and the second indicator are respectively disposed.

[0016] Compared with existing technologies, the beneficial effects of the rabbit ear vein injection simulation training device provided in this embodiment are as follows: By setting up an ear vein model, using an insulating sleeve to simulate blood vessels and a conductive core to simulate blood, combined with an indicator circuit to replace the traditional silicone blood vessel form, the rabbit ear vein injection simulation training device is structurally and functionally closer to a real rabbit ear vein injection scenario. When students use the rabbit ear vein injection simulation training device for training, they can obtain a more similar tactile and visual feedback to actual operation, thereby better mastering injection techniques and improving training effectiveness. In addition, the puncture-proof layer effectively avoids the risk of students being pricked by the puncture needle during training. Compared with existing training devices where puncture models can cause finger injuries, this design significantly improves the safety of the training device and provides students with a more reliable training environment. The indicator circuit design can clearly indicate the position of the puncture needle through the first and second indicators. When the puncture needle accurately penetrates the conductive core (simulating blood in a blood vessel), the circuit containing the first indicator is activated, indicating a successful puncture. When the puncture needle penetrates the conductive layer (simulating tissue outside the blood vessel), the circuits containing both the first and second indicators are activated simultaneously, or only the circuit containing the second indicator is activated, indicating a failed puncture. This accurate feedback mechanism helps students promptly identify problems during the procedure, adjust their methods, improve the success rate, and avoid leakage during training.

[0024] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The preferred embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0025] like Figure 1 and Figure 2 As shown, this utility model embodiment provides a rabbit ear vein injection simulation training device 100, including: a rabbit ear model 110, a syringe 120, and an indicator circuit 130. The rabbit ear model 110 is provided with at least one ear vein model 112. The ear vein model 112 includes an insulating sleeve 1122 for simulating blood vessels and a conductive core 1124 for simulating blood. The conductive core 1124 is located in the inner ring of the insulating sleeve 1122. A puncture-proof layer 140 is provided on one side of the rabbit ear model 110. A conductive layer 150 is provided between the puncture-proof layer 140 and the ear vein model 112. The indicator circuit 130 includes a power supply 132, a first indicator 134 and a second indicator 136 electrically connected to one electrode of the power supply 132, and the first indicator 134 and the second indicator 136 are connected in parallel. The first indicator 134 is electrically connected to the conductive core 1124, and the second indicator 136 is electrically connected to the conductive layer 150 and to the other electrode of the syringe 120 and the power supply 132.

[0026] Specifically, at least one auricular vein model 112 is disposed inside the rabbit ear model 110. The auricular vein model 112 is a key component of the simulation training device. The auricular vein model 112 is composed of an insulating sleeve 1122 for simulating blood vessels and a conductive core 1124 for simulating blood, wherein the conductive core 1124 is located in the inner ring of the insulating sleeve 1122. The insulating sleeve 1122 simulates the physical shape and isolation characteristics of real blood vessels, enclosing the conductive core 1124, which simulates blood. Its conductivity is an important basis for realizing the injection effect indication. A puncture-proof layer 140 is disposed on one side of the rabbit ear model 110, and a conductive layer 150 is disposed between the puncture-proof layer 140 and the auricular vein model 112. The function of the puncture-proof layer 140 is to prevent the puncture needle 124 from puncturing the model due to improper operation during training, thereby avoiding finger injuries and ensuring the personal safety of the user. The indicating circuit 130 connects a first indicator 134 and a second indicator 136 in parallel. The first indicator 134 is electrically connected to the conductive core 1124, and the second indicator 136 is electrically connected to the conductive layer 150. The syringe 120 is electrically connected to the other electrode of the power supply 132. This circuit design allows feedback to be provided by the first indicator 134 or the second indicator 136 when the puncture needle 124 of the syringe 120 punctures different locations, thereby helping the user determine whether the puncture was successful.

[0027] When there are two or more auricular vein models 112, the auricular vein models 112 are connected in parallel and electrically connected to the indicator circuit 130 respectively.

[0028] The rabbit ear vein injection simulation training device 100 provided in this application embodiment uses an ear vein model 112, an insulating sleeve 1122 to simulate blood vessels, a conductive core 1124 to simulate blood, and an indicator circuit 130 to replace the traditional silicone blood vessel form. This makes the rabbit ear vein injection simulation training device 100 structurally and functionally closer to a real rabbit ear vein injection scenario. When students use this rabbit ear vein injection simulation training device 100 for training, they can obtain a more similar tactile and visual feedback to actual operation, thereby better mastering injection techniques and improving training effectiveness. In addition, the anti-puncture layer 140 effectively avoids the risk of students being pricked by the puncture needle 124 during training. Compared with existing training devices where puncture models can cause finger injuries, this design significantly improves the safety of the training device and provides students with a more reliable training environment. The indicator circuit 130 is designed to clearly indicate the position of the puncture needle 124 through the first indicator 134 and the second indicator 136. When the puncture needle 124 accurately punctures the conductive core 1124 (simulating blood in a blood vessel), the circuit containing the first indicator 134 is activated (e.g., Figure 3As shown), the puncture is successful; when the puncture needle 124 punctures the conductive layer 150 (simulating tissue outside the blood vessel), the circuit containing the first indicator 134 and the second indicator 136 is simultaneously turned on (as shown). Figure 4 (As shown), or only the circuit containing the second indicator 136 is active, indicating a failed puncture. This accurate feedback mechanism helps students promptly identify problems during the procedure, adjust their methods, improve the success rate, and avoid leakage during training.

[0029] like Figure 2 As shown, the syringe 120 includes a syringe 122 and a puncture needle 124 connected to the syringe 122. The power supply 132 is electrically connected to the puncture needle 124 so that when the puncture needle 124 punctures the conductive core 1124, the circuit of the first indicator 134 is turned on, and when the puncture needle 124 punctures the conductive layer 150, the circuit of the second indicator 136 is turned on at the same time.

[0030] Specifically, when the puncture needle 124 punctures the conductive core 1124, since the conductive core 1124 is electrically connected to the first indicator 134 and the puncture needle 124 is electrically connected to the other electrode of the power supply 132, the circuit containing the first indicator 134 is turned on. Similarly, when the puncture needle 124 punctures the conductive layer 150, the circuit containing the second indicator 136 is simultaneously turned on. Through this design, the effective linkage between the puncture needle 124 and the indicator circuit 130 is achieved, enabling the indicator to accurately reflect the position of the puncture needle 124.

[0031] In an optional embodiment of this application, the conductive core 1124 and the conductive layer 150 are made of conductive silicone.

[0032] Specifically, conductive silicone is a material with excellent conductivity and flexibility, which can meet the requirements of circuit conduction while simulating blood and extravascular tissue. Its flexibility allows the resistance and elasticity felt during puncture to more closely resemble reality, helping students more accurately grasp the puncture force and angle, thus improving the realism and effectiveness of training. Furthermore, compared to some materials that may leak and affect the circuitry after repeated use, conductive silicone does not have leakage problems, ensuring the reliability and lifespan of the device and reducing maintenance costs.

[0033] In an optional embodiment of this application, the puncture-resistant layer 140 is made of puncture-resistant fabric.

[0034] Specifically, the high strength of the puncture-resistant fabric reliably resists penetration by the puncture needle 124, providing a solid safety barrier for the user. Compared to other ordinary materials, the puncture-resistant fabric more effectively prevents accidental punctures, further enhancing the safety of the training device and giving students greater peace of mind during training. Furthermore, while possessing high strength, the puncture-resistant fabric also exhibits good flexibility, ensuring it does not affect the overall shape and feel of the rabbit ear model 110.

[0035] like Figure 2 As shown, the first indicator 134 includes a first indicator light 1342.

[0036] Specifically, the first indicator light 1342 provides students with a clear and intuitive indication of the puncture result through a bright light signal. During training, students do not need complex judgments; they can quickly determine whether the puncture was successful simply by observing the on / off state of the first indicator light 1342. This intuitive feedback helps students quickly understand the operation result and adjust their operation strategy in a timely manner. In teaching scenarios, there may be multiple students training simultaneously or teachers providing guidance. The design of the first indicator light 1342 allows the training result to be clearly displayed to those around them, facilitating timely guidance from teachers and enabling students to learn from and communicate with each other, thereby improving teaching efficiency.

[0037] In an optional embodiment of this application, the first indicator 134 further includes a first horn 1344 connected in series with the first indicator light 1342.

[0038] Specifically, the first speaker 1344 and the first indicator light 1342 work together. When the circuit containing the first indicator 134 is turned on, not only does the first indicator light 1342 light up, but the first speaker 1344 also emits an audio signal. This combined audio-visual indication method can convey the information of a successful puncture to the user from multiple sensory dimensions. In addition, the combined use of the first speaker 1344 and the first indicator light 1342 has wider applicability. For example, in brightly lit environments, the brightness of the first indicator light 1342 may not be obvious enough and may be easily overlooked; or students may ignore visual cues when focusing on the operation. In this case, the sound emitted by the first speaker 1344 can compensate for these deficiencies.

[0039] In an optional embodiment of this application, the second indicator 136 includes a second indicator light 1362.

[0040] Similarly, the second indicator light 1362 provides students with a clear and intuitive indication of the puncture result through a bright light signal. During training, students do not need complex judgments; they can quickly determine whether the puncture was successful simply by observing the on / off state of the second indicator light 1362. This intuitive feedback helps students quickly understand the operation result and adjust their operation strategy in a timely manner. In teaching scenarios, there may be multiple students training simultaneously or teachers providing guidance. The design of the second indicator light 1362 allows the training results to be clearly displayed to those around them, facilitating timely guidance from teachers and enabling students to learn from and communicate with each other, thereby improving teaching efficiency.

[0041] In an optional embodiment of this application, the second indicator 136 further includes a second horn 1364 connected in series with the second indicator light 1362.

[0042] Similarly, the second speaker 1364 works in conjunction with the second indicator light 1362. When the circuit containing the second indicator 136 is activated, not only does the second indicator light 1362 illuminate, but the second speaker 1364 also emits an audible signal. This combined sound and light indication method can convey information about puncture failure to the user from multiple sensory dimensions. Furthermore, the combined use of the second speaker 1364 and the second indicator light 1362 has broader applicability. For example, in brightly lit environments, the brightness of the second indicator light 1362 may not be obvious enough and easily overlooked; or students may ignore visual cues while focusing on the operation. In these cases, the sound emitted by the second speaker 1364 can compensate for these deficiencies.

[0043] like Figure 2 As shown, the indicator circuit 130 also includes a switch, which is connected in series with one electrode of the power supply 132.

[0044] Specifically, the switch controls the on / off state of the indicator circuit 130. When the switch is open, the indicator circuit 130 is connected to the power supply 132 and is in working condition; when the switch is closed, the indicator circuit 130 is disconnected from the power supply 132 and stops working. Furthermore, the switch allows users to flexibly control the operating state of the indicator circuit 130 according to actual needs. During device maintenance or inspection, turning off the switch also ensures operational safety and prevents problems such as short circuits caused by misoperation.

[0045] In an optional embodiment of this application, the indicator circuit 130 further includes a support, and the first indicator 134 and the second indicator 136 are respectively disposed on the support.

[0046] Specifically, fixing the first indicator 134 and the second indicator 136 to the support can prevent the first indicator 134 and the second indicator 136 from being damaged due to shaking, collision or other reasons during use, thereby enhancing the stability and durability of the entire indicator circuit 130.
