[0028] In order to make the technical problems, technical solutions and beneficial effects solved by the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0029] like Figures 1 to 4 As shown, a ventilator provided by one embodiment of the utility model includes a ventilator housing 1, a breathing module, a sputum discharge module, a main board 4 and a lung sound detection module 5. The ventilator housing 1 has a cavity, and the breathing module, the sputum discharge module and the main board 4 are all arranged in the cavity, which is convenient for carrying and transporting the ventilator. The breathing module is used to assist the patient's breathing.

[0030] The lung sound detection module 5 includes a detection probe 51 and a plug connector 52. An interface is provided on the ventilator housing 1. The plug connector 52 is plugged into the interface. The interface is electrically connected to the expectoration module through the main board 4. The detection probe 51 and the plug connector 52 are electrically connected through a cable. The detection probe 51 is used to collect lung sound signals of the human body. The main board 4 can control the expectoration module to assist the patient in expectoration according to the lung sound signals. Among them, the detection probe 51 is attached to the middle position of the human body's clavicle. The patient's respiratory resistance can be judged by the collected lung sound signals, and then the patient's sputum accumulation can be judged. According to the sputum accumulation, the main board 4 controls the expectoration module to start and help the patient expectorate. In this process, expectoration can be achieved without pulling out the patient's respiratory tube 6, which can reduce the patient's treatment pain and avoid causing secondary infection to the patient. In addition, by attaching the detection probe 51 to the human body, the patient's breathing condition can be detected in real time to achieve an early warning function.

[0031] In this embodiment, the ventilator has a breathing mode and a sputum discharge mode. When the ventilator is in the breathing mode, the main board 4 controls the operation of the breathing module to help the patient breathe. When the detection probe 51 collects lung sound signals, the main board 4 determines that sputum discharge is required based on the lung sound signals, and then turns off the breathing module and switches to the sputum discharge mode. The sputum discharge module runs to help the patient discharge sputum. The ventilator can switch back and forth between the breathing mode and the sputum discharge mode, and integrates the ventilator function and the sputum discharge machine function, which improves its applicability and versatility, realizes multiple uses of one machine, and reduces medical costs.

[0032] In one embodiment, the detection probe 51 includes a shell and a sensor disposed in the shell, wherein the sensor is electrically connected to the main board 4, wherein the sensor is a sound sensor, which is attached to the human body and can detect lung sounds, and the lung sound signal is fed back to the main board 4, thereby realizing real-time detection and early warning functions of sputum.

[0033] In one embodiment, if Figure 3 As shown, the sputum discharge module includes a negative pressure drive 31 and an exhalation valve 32, and the negative pressure drive 31 is electrically connected to the main board 4. The ventilator also includes a breathing circuit 6, which is arranged between the ventilator and the patient, and the exhalation valve 32 is connected between the negative pressure drive 31 and one end of the breathing circuit 6, and the other end of the breathing circuit 6 is used to connect a breathing mask, which is worn on the patient's face. When the sputum discharge mode is started, the main board 4 controls the negative pressure drive 31 to start, so that the exhalation valve 32, the breathing tube and the breathing mask can form a negative pressure environment, so that the sputum accumulated in the patient's lungs or throat can be extracted.

[0034] The negative pressure driving member 31 may be, but is not limited to, an air suction turbine. When the air suction turbine is started, negative pressure is generated by suctioning the connected exhalation valve 32 and the breathing circuit 6 .

[0035] In one embodiment, if Figure 3 As shown, the sputum discharge module also includes a first stop valve 33, the first stop valve 33 is electrically connected to the main board 4, and the first stop valve 33 is connected between the negative pressure drive 31 and the exhalation valve 32. When the ventilator is in the breathing mode, the first stop valve 33 is in a closed state, and the negative pressure drive 31 and the exhalation valve 32 cannot be connected. When the ventilator is in the sputum discharge mode, the first stop valve 33 is in an open state, and the negative pressure drive 31 and the exhalation valve are connected, so that the exhalation valve 32 and the breathing circuit 6 can be evacuated. The sputum discharge mode can be turned on and off by the first stop valve 33, avoiding interference between the sputum discharge mode and the breathing mode.

[0036] In one embodiment, if Figure 2As shown, the breathing module includes an air intake component and an inhalation valve 23. The air intake end of the air intake component is used to connect to an air source, which is an air source or an oxygen source. The inhalation valve 23 is connected between the air outlet end of the air intake component and one end of the breathing circuit 6. The gas enters through the air intake end of the air intake component, flows out from the air outlet end of the air intake component, flows through the inhalation valve 23 and the breathing pipeline in turn, and is supplied to the patient through the breathing mask connected to the breathing circuit 6, thereby helping the patient breathe.

[0037] In one embodiment, if Figure 2 As shown, the air intake assembly includes an oxygen intake member 21 and a turbine 22. The intake end of the oxygen intake member 21 is used to connect to an oxygen source, which is a high-pressure oxygen cylinder or a low-pressure oxygen cylinder. The intake end of the turbine 22 is used to introduce air, which is a high-pressure air cylinder or an air compressor. The outlet end of the oxygen intake member 21 is connected to the intake end of the turbine 22. The outlet end of the turbine 22 is connected to the inlet valve 23. The external oxygen source is input to the turbine 22 through the oxygen intake member 21. The external air is input through the intake end of the turbine 22. The air and oxygen are mixed inside the turbine 22 and then output to the inlet valve 23, thereby delivering the air-oxygen mixed gas to the patient. It can be understood that the air source connected to the intake assembly is determined according to the patient's needs, and air, oxygen, or an air-oxygen mixed gas can be delivered to the patient.

[0038] The gas exhaled by the patient enters the exhalation valve 32 through the breathing mask and the breathing tube 6. At this time, the first stop valve 33 is in a closed state, and the exhalation valve 32 discharges the gas exhaled by the patient into the external environment.

[0039] In one embodiment, if Figure 1 As shown, the breathing circuit 6 includes an inhalation tube 61, an exhalation tube 62, a sputum tank 63 and a connecting tube 64, the sputum tank 63 is connected to the connecting tube 64, the inhalation tube 61 is connected between one end of the connecting tube 64 and the inhalation valve 23, the exhalation tube 62 is connected between one end of the connecting tube 64 and the exhalation valve 32, and the other end of the connecting tube 64 is connected to the breathing mask.

[0040] When the ventilator is in breathing mode, the air intake assembly is connected to the air source, and the gas is delivered to the inhalation valve 23 through the turbine 22. The inhalation valve 23 delivers the gas to the patient through the inhalation pipe 61 and the connecting pipe 64. The gas exhaled by the patient enters the exhalation valve 32 through the connecting pipe 64 and the exhalation pipe 62, and the exhalation valve 32 discharges the gas exhaled by the patient into the external environment.

[0041] When the ventilator is in the sputum discharge mode, the negative pressure driving element 31 draws air through the exhalation valve 32, the exhalation tube 62 and the connecting tube 64 to form a negative pressure, which can extract the sputum accumulated in the patient's lungs or throat. The sputum enters the sputum tank 63 through the connecting tube 64, thereby facilitating the centralized collection of the sputum.

[0042] The sputum tank 63 is detachably connected to the connecting tube 64 , so that the sputum tank 63 can be easily cleaned.

[0043] In one embodiment, if Figure 2 As shown, the breathing module also includes a pressure relief valve 24, which is electrically connected to the main board 4, and is connected between the outlet end of the air intake assembly and the inhalation valve 23. The gas pressure can be monitored by a pressure sensor. When the gas pressure is too high, the gas can be discharged to the outside through the pressure relief valve 24 to reduce the gas pressure and avoid excessive pressure affecting the patient's breathing. Further, the pressure relief valve 24 is arranged between the turbine 22 and the inhalation valve 23, and the pressure relief valve 24 can prevent the pressure of the air-oxygen mixed gas output by the turbine 22 from being too high.

[0044] In one embodiment, if Figure 2 As shown, the breathing module also includes a second stop valve 25, which is connected between the pressure relief valve 24 and the inhalation valve 23. When the ventilator is in the breathing mode, the second stop valve 25 is in an open state, and the turbine 22 is connected to the inhalation valve 23 through the pressure relief valve 24, which can ensure that the turbine 22 delivers gas to the patient. When the ventilator is in the sputum discharge mode, the second stop valve 25 is in a closed state, and the delivery of gas to the patient is stopped. The second stop valve 25 can realize the opening and closing of the breathing mode, avoiding affecting the sputum discharge effect when the sputum discharge mode is running.

[0045] In one embodiment, if Figure 1 As shown, the ventilator housing 1 includes a rear shell 11 and a front shell 12, the front shell 12 is connected to the rear shell 11 and encloses a cavity, and the interface is arranged on the rear shell 11. A display screen 121 is arranged on the front shell 12, and the display screen 121 can display the working mode of the ventilator and sputum warning, so that the user can grasp the use status in time, and improve the user experience of the ventilator.
