[0002] In modern clinical medicine, ventilators, as an effective means of artificially replacing spontaneous ventilation, are widely used in respiratory failure caused by various reasons, anesthetic respiratory management during major surgery, respiratory support therapy, and emergency resuscitation. They occupy a very important position in the field of modern medicine, and their performance stability and accuracy directly affect patient safety. After a period of use, the technical indicators of a ventilator, such as respiratory rate, airway pressure, and tidal volume, will deviate, sometimes with significant errors. Clinically, a ventilator simulator is usually used to test the various technical indicators of the ventilator in order to correct the parameters. Clinicians can roughly judge the performance of the ventilator by using this device. However, because the simulator is connected to the airway of the used ventilator, it will retain many bacteria. Therefore, the use of simulators often causes contamination of the ventilator tubing and may also lead to the widespread spread of multidrug-resistant bacteria, increasing the risk of infection for patients.

[0003] Therefore, there is an urgent need to design a new type of ventilator to simulate a lung in order to solve the above problems. Utility Model Content

[0025] To enable those skilled in the art to better understand the technical solution of this utility model, the technical solution of this utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0026] Example:

[0027] See attached document Figure 1-7 The novel ventilator-simulated lung shown includes a splint 1, an air bag 2, a connector 3, and a fixing member 4. The air bag 2 is movably inserted into the splint 1 and fixed to the splint 1 by the fixing member 4. The connector 3 is movably inserted into the port of the air bag 2 and sleeved inside the splint 1. The splint 1 is made of rigid plastic and has a double-layer folding structure, with the upper and lower layers able to be separated or combined. The air bag 2 is transparent, with a commonly used size of 600ml, but its size can be changed according to actual needs to meet the performance requirements of different ventilators. The connector 3 and the fixing member 4 can be made of metal or rigid plastic, preferably rigid plastic, to reduce the overall weight.

[0028] Specific examples Figure 2As shown, the clamp 1 includes clamp 101 and clamp 2 102. One end of clamp 101 and clamp 2 102 are connected in a U-shape, and the other end is provided with a fixing hole 103. U-shaped notches are also provided on clamp 101 and clamp 2 102. This design allows for convenient placement of the air bag 2 and facilitates observation of the air bag 2. The U-shaped notches are also used in conjunction with connector 3 to further secure the air bag 2. The sides of clamp 101 and clamp 2 102 are open, allowing for a larger area of ​​observation of the air bag 2. Manually pulling clamp 101 and clamp 2 102 simulates spontaneous breathing by the patient. By observing the waveform, loop diagram, and changes in the detection values ​​of the ventilator, the triggering and operation of the ventilator in different modes can be determined. This helps to fully understand the performance of the ventilator and ensure that it can work normally under various conditions. During disinfection, repeatedly pulling outward and retracting clamp 101 and clamp 2 102 helps the disinfectant to disinfect the inner cavity of the air bag 2 more efficiently.

[0029] Specific examples Figure 3-4 As shown, the airbag 2 includes an X-shaped airbag body 201 and an air exchange port 202. The air exchange port 202 is disposed and connected to one end of the airbag body 201. The other end of the airbag body 201 is provided with a fixing part 203 adapted to the clamp 1. When the airbag 2 is disposed between the clamp 101 and the clamp 202, the fixing member 4 passes through the fixing hole 103 on the clamp 101 and the clamp 202 and the fixing hole 203-1 on the fixing part 203, fixing the clamp 101, the clamp 202 and the tail of the airbag 2 together.

[0030] Furthermore, the outer periphery of the ventilation port 202 is provided with an external thread 202-1, the fixing part 203 has a Y-shaped structure and is connected to the end of the airbag 2, and a fixing hole 203-1 adapted to the fixing hole 103 is provided on the fixing part 203.

[0031] Specific examples Figure 5-6 As shown, connector 3 has a cross-shaped structure, including a connecting pipe 301, a ventilation pipe 302, a first cleaning pipe 303, and a second cleaning pipe 304. The upper end of the connecting pipe 301 is provided with an internal thread 202-1 that mates with the external thread 202-1. A partition 301-1 is provided inside the connecting pipe 301, dividing the inner cavity of the connecting pipe 301 into two independent left and right chambers. The ventilation pipe 302 passes through the connecting pipe 301 from top to bottom and communicates with the left chamber on the left side of the partition 301-1. The second cleaning pipe 304 is located on the left side of the connecting pipe 301 and communicates with the left chamber on the left side of the partition 301-1. The first cleaning pipe 303 is located on the right side of the connecting pipe 301 and communicates with the right chamber on the right side of the partition 301-1. A silicone cap 302-1 is provided at the bottom of the ventilation pipe 302, and silicone caps 303-1 are provided at the ends of both the first cleaning pipe 303 and the second cleaning pipe 304.

[0032] Among them, the ventilation tube 302 is used to connect to the ventilator and to judge the performance of the ventilator; the first cleaning tube 303 is used to deliver air into the air bag 2; the second cleaning tube 304 is used to expel the air from the air bag 2; and the first cleaning tube 303 and the second cleaning tube 304 are also used to cooperate with the clips 101 and 102, which are provided with U-shaped notches, to further fix the air bag 2.

[0033] Specific examples Figure 7 As shown, the fastener 4 has an I-shaped structure, including a matching T-shaped fastening part 401 and a fastening cap 402. The lower end of the T-shaped fastening part 401 is provided with an external thread, and the fastening cap 402 is provided with an internal thread that matches the external thread.

[0034] The principle and process of using the novel ventilator simulated lung in this preferred embodiment are as follows: First, the internal thread of the connecting tube 301 is matched with the external thread 202-1 on the ventilation port 202, so that the connector 3 is screwed onto the air bag 2. Then, from the end direction of the clip 101 and clip 202, the clip 101 and clip 202 are separated and the air bag 2 is inserted, so that the air bag 2 extends out of the front end of the clip 101 and clip 202. At the same time, the cleaning tube 103 and cleaning tube 204 on the connector 3 are locked at the U-shaped notch on the clip 101 and clip 202. Finally, the T-shaped fixing part 401 is passed through the fixing hole 103 and fixing hole 203-1, and the fixing cap 402 is screwed onto the end of the T-shaped fixing part 401 from the other side to complete the fixing of the air bag 2 and the clip 1.

[0035] When testing the ventilator's performance, remove the silicone cap 302-1 and connect the lower end of the ventilation tube 302 to the ventilator for adjustment. At this time, gas flows from the ventilator tubing through the ventilation tube 302 into the cuff 2. Doctors can observe the ventilator's waveform, loop diagram, and changes in measured values ​​to determine the ventilator's triggering and operation in different modes. This allows for a comprehensive understanding of the ventilator's performance and facilitates adjustments, ensuring it functions properly under various conditions.

[0036] After the simulated lung is used, disinfectant is first injected into the air bladder 2 through the end of the ventilation tube 302 to disinfect the inner cavity of the air bladder 2 and the inside of the ventilation tube 302. After disinfection, silicone cap 302-1 is put on, and then silicone cap 303-1 on cleaning tube 303 is removed. Hot air is blown into the air bladder 2 through cleaning tube 303. After the air bladder 2 is inflated and reaches a certain pressure, silicone cap 303-1 and silicone cap 302-1 on cleaning tube 304 are removed, allowing gas to slowly escape from cleaning tube 304 and ventilation tube 302. At the same time, hot air is still being blown into cleaning tube 303. After the moisture in the air bladder 2 has completely evaporated and the air bladder 2 is dry, the blowing is stopped, and silicone caps 302-1 and 303-1 are placed on ventilation tube 302, cleaning tube 303, and cleaning tube 304 for the next use.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
