[0002] This part provides only background information related to the present disclosure, which is not necessarily prior art.

[0003] Subcutaneous injection is a common drug administration method that injects drugs into subcutaneous tissue, has the advantages of simple operation, stable drug absorption, etc., and is widely used in vaccination, chronic disease treatment and emergency medical scenarios. Since there are many inconveniences in practicing injection on patients, subcutaneous injection models have become a key tool for classroom teaching, after-school training in medical colleges and universities, and training of junior nurses in hospitals, aiming to help students master the operation skills.

[0004] The existing subcutaneous injection model has obvious shortcomings, which restricts the training effect: first, the model cannot provide depth feedback, making it difficult for the operator to determine whether the injection is accurate; the whole operation process lacks real-time feedback mechanism. Secondly, the model is not wearable, and the common injection sites of subcutaneous injection are the outer side of the upper arm, the abdomen, and the front and outer side of the thigh. The existing model is not wearable, cannot simulate puncture in different parts, has no experience, and the practice scene is greatly limited, making it difficult to simulate the real clinical environment. These defects directly affect the training efficiency and skill improvement of nurses and medical students. SUMMARY

A training monitoring mechanism is designed based on the principle of electrical contact sensing: conductive sensing devices are implanted in the subcutaneous tissue layer and the muscle layer respectively. During the puncture process, the needle tip contacts the subcutaneous layer sensing unit to trigger a green light signal, and continues to penetrate to the muscle layer to trigger a red warning, so that the real-time visual monitoring of the puncture depth is realized through the photoelectric cooperative feedback.

[0023] The reference signs in the drawings are as follows: 1-analog injection module; 101-silicone layer; 102-first conductive cloth; 103-second conductive cloth; 104 first sponge layer; 105-third conductive cloth; 106-third sponge layer; 2-upper cover; 3-power switch; 4-first indicator light; 5-second indicator light; 6-hanging ear; 7-lower cover; 8-power supply; 9-control module; 10-buckle; 11-buckle hole.

[0024] As shown in the drawings, Figures 1-2 A wearable inductive subcutaneous injection training model includes a shell, an analog injection module 1, a power supply 8 and a control module 9, which are respectively arranged in the shell, and the analog injection module 1 and the power supply 8 are respectively connected with the control module 9. An injection operation window is provided on the shell, and the injection area of the analog injection module 1 is exposed to the injection operation window. The shell is provided with a hanging ear 6.

[0025] The analog injection module 1 includes a silicone layer 101, a first conductive cloth 102, a second conductive cloth 103, a first sponge layer 104, a third conductive cloth 105 and a second sponge layer 106 arranged in sequence; an insulating layer is arranged between the first conductive cloth 102 and the second conductive cloth 103, and the first conductive cloth 102, the second conductive cloth 103 and the third conductive cloth 105 are respectively connected with the control module.

[0026] The thickness of the first sponge layer 104 and the second sponge layer 106 is 4-5mm. The thickness of the analog injection module 1 is 1-1.5cm.

[0027] The first sponge layer 104 and the second sponge layer 106 in the analog injection module 1 are made of different materials. The first sponge layer is a porous gradient sponge simulating the subcutaneous tissue layer, and the second sponge layer is a high polymer sponge simulating the muscle layer.

[0028] The outer casing includes an upper cover 2 and a lower cover 7, which are connected by a connecting assembly.

[0029] The connecting component includes a buckle 10 located at the lower end of the upper cover 2 and a buckle hole 11 located at the upper end of the lower cover 7; the buckle 10 matches the buckle hole 11.

[0030] The outer casing is equipped with a first indicator light 4 (green light) and a second indicator light 5 (red light).

[0031] The outer casing is equipped with a power switch 3. The model is equipped with an alarm.

[0032] like Figures 3-4 As shown, the first conductive cloth (A) is connected to the positive terminal of the main bus; the second conductive cloth (B) is connected to the positive terminal of the green light through a resistor, and the negative terminal of the green light is connected to the common ground; the third conductive cloth (C) is connected to the positive terminal of the red light through a resistor, and the negative terminal of the red light is connected in parallel with the positive terminal of the alarm, and the negative terminal of the alarm is connected to the common ground. When the syringe needle pierces the silicone layer, it only contacts the first conductive cloth, and no electrical path is formed, so the light does not illuminate. When the needle pierces the first sponge layer (i.e., the subcutaneous tissue layer), the syringe needle contacts both the first and second conductive cloths, and a path is formed between the first conductive cloth, the syringe needle, the second conductive cloth, the green light, the battery, and the circuit board, thus illuminating the green light. When the needle pierces the second sponge layer (i.e., the muscle layer), a path is formed between the needle, the first and third conductive cloths, the signal amplifier, the red light, the buzzer, the battery, and the circuit board, illuminating the red light and triggering the buzzer. The signal amplifier is used to detect signal changes. The circuit is a parallel circuit. If the green light circuit is powered alone, and the signal does not exceed the set threshold, the signal amplifier will power the green light circuit normally. If the red and green light circuits are powered on together, the voltage will exceed the rated voltage, and the signal amplifier will automatically cut off the green light circuit.

[0033] The steps for using the device are as follows:

[0034] Step 1: Turn on the power. Before use, turn on the power switch on the device.

[0035] Step 2: Wear the device and place the training model on the injection site (upper arm deltoid, abdomen, front of thigh, buttocks, etc.) where the simulation exercise is needed.

[0036] Step 3: Perform injection practice. Conduct a standard subcutaneous injection in the exposed injection area of ​​the model. Observe and provide feedback during the procedure. If the needle depth is correct (i.e., the first and second conductive fabrics are pierced), the first indicator light (green) will illuminate. If the needle depth is too deep (i.e., the first, second, and third conductive fabrics are all pierced), the second indicator light (red) will illuminate, and an alarm will sound.

[0037] Step 4, turn off the power switch on the device after completing the simulation practice. Take the device off the wearing site and save it for next use.

[0038] The application provides a wearable inductive subcutaneous injection training model, and the method and approach for specifically implementing the technical solution are various.

The components not explicitly described in the embodiment can be implemented by using the existing technology.
