Description

Technical Field

[0001] This disclosure relates to the field of medical devices, specifically to multi-person ventilators. Background Technology

[0002] A ventilator is a device that can replace, control, or alter a person's normal physiological breathing, increase lung ventilation, improve respiratory function, reduce the work of breathing, and conserve cardiac energy reserves. Therefore, ventilators have become indispensable equipment in clinical treatment.

[0003] Currently, ventilators are typically used by one patient per machine and cannot serve multiple patients simultaneously. Therefore, when there are many patients, a shortage of ventilators often occurs.

[0004] Therefore, a new type of ventilator is needed to solve the above problems. Summary of the Invention

[0005] The summary portion of this disclosure is intended to provide a brief overview of the concepts, which will be described in detail in the detailed description portion. This summary portion is not intended to identify key or essential features of the claimed technical solutions, nor is it intended to limit the scope of the claimed technical solutions.

[0006] To address the aforementioned problem—that current ventilators cannot serve multiple patients simultaneously—some embodiments of this disclosure propose a multi-patient ventilator, comprising: a ventilator body including an air delivery end and an exhaust end; an air delivery main line and an exhaust main line, a first end of the air delivery main line connected to the air delivery end, and a first end of the exhaust main line connected to the exhaust end; and a splitter assembly including a first splitter and a second splitter, the first splitter being connected to the second end of the air delivery main line for dividing the air delivery main line into multiple air delivery branch lines; and the second splitter being connected to the second end of the exhaust main line for dividing the exhaust main line into multiple exhaust branch lines, the number of exhaust branch lines corresponding to the number of air delivery branch lines.

[0007] In some embodiments, the first splitter includes a first air inlet, a first air storage chamber, and a plurality of first air outlets connected together. In the assembled state, the first air inlet is connected to the main air supply pipeline, and each of the first air outlets is connected to one of the branch air supply pipelines. The first air storage chamber is also provided with a water-absorbing component, which is used to absorb moisture in the main air supply pipeline.

[0008] In some embodiments, the second splitter includes a connected second air outlet, a second air storage chamber, and a plurality of second air inlets. In the assembled state, the second air outlet is connected to the exhaust main pipeline, and each of the second air inlets is connected to one of the exhaust branch pipelines. A disinfection spraying device is provided in the second air storage chamber, and the disinfection spraying device sprays the second air storage chamber within a preset time.

[0009] In some embodiments, a one-way valve is provided on the gas supply branch line, which is used to restrict the gas flow direction in the gas supply branch line.

[0010] In some embodiments, a filter is provided on the gas supply branch line, and the filter is used to filter impurities or bacteria in the gas supply branch line.

[0011] In some embodiments, a gas flow meter is further provided on the gas supply branch pipe and the gas exhaust branch pipe respectively, and the gas flow meter is used to detect the flow rate of gas in the gas supply branch pipe and the gas exhaust branch pipe.

[0012] In some embodiments, a flow regulating component is further provided on the gas supply branch line, which is used to regulate the flow rate of gas in the gas supply branch line.

[0013] In some embodiments, the multi-person ventilator further includes a flow controller, the flow controller, the gas flow meter, and the flow regulating component are communicatively connected. In response to a discrepancy between the gas flow value received from the gas flow meter and a preset flow value, the flow controller controls the flow regulating component to adjust the gas flow in the gas delivery branch. The preset flow value is obtained by analyzing the patient's age using an artificial intelligence chip included in the flow controller. The machine learning model carried by the artificial intelligence chip has been trained using a training sample set.

[0014] In some embodiments, the training sample set includes the age of the sample patients and the preset flow rate of the samples. The machine learning model is trained using the age of the sample patients as input and the preset flow rate of the samples as the expected output.

[0015] One embodiment of the above-described embodiments of this disclosure has the following beneficial effects: by dividing the above-described air supply main line and exhaust main line into multiple branches by a splitter assembly, the above-described multi-person ventilator can be provided to multiple people for simultaneous use, thereby improving the efficiency of ventilator use.

[0025] This disclosure will now be described in detail with reference to the accompanying drawings and embodiments.

[0026] First refer to Figure 1 , Figure 1 This is a structural schematic diagram of a multi-person ventilator based on this disclosure; such as Figure 1 As shown, the multi-person ventilator includes a ventilator body 1, a splitter assembly, a main gas delivery line 21, and a main exhaust line 22. Specifically, the ventilator body 1 includes a gas delivery end 11 and an exhaust end 12 fixed to the ventilator body 1. The gas delivery end 11 is used to output gas and deliver it into the patient's body through the tubing. The exhaust end 12 is used to receive the gas expelled by the patient.

[0027] The first end of the aforementioned gas supply main line 21 ( Figure 1 The end of the ventilator body 1 is connected to the air delivery end 11, and the first end of the exhaust pipe 22 is connected to the air delivery end 11. Figure 1 The end of the ventilator near the main body 1 is connected to the exhaust end 12.

[0028] The aforementioned splitter assembly may include a first splitter 31 and a second splitter 32. The first splitter 31 divides the aforementioned main gas supply line 21 into two gas supply branch lines 411 and 412. The second splitter 32 divides the aforementioned main exhaust line 22 into two exhaust branch lines 421 and 422. It should be noted that the number of the aforementioned two gas supply branch lines 411 and 412, and the number of exhaust branch lines 421 and 422 are exemplary. Those skilled in the art can adjust the number of the aforementioned gas supply branch lines and exhaust branch lines as needed, and such changes do not exceed the scope of protection of this disclosure. Specifically, the first splitter 31 and the second end of the aforementioned main gas supply line 21 ( Figure 1 The second branch circuit 32 is connected to the second end of the exhaust main pipe 22 (the end opposite to the ventilator body 1). Figure 1The end of the ventilator (away from the main body 1) is connected. The number of exhaust branches corresponds to the number of inlet branches. In operation, one inlet branch and one exhaust branch deliver gas to a patient and remove the patient's exhaled gas. Since the first splitter 31 and the second splitter 32 can have the same structure, the first splitter will be used as an example for explanation. The first splitter can be composed of multiple T-tubes or Y-tubes connected together. For example, by connecting one T-tube to the main inlet branch, two inlet branches can be branched out. As another example, by connecting one end of one T-tube to the main inlet branch, and then connecting another T-tube to each of the other two ends of the T-tube, four inlet branches can be branched out from the main inlet branch. It should be noted that those skilled in the art can adjust the number of T-tubes according to actual conditions. However, such changes do not exceed the scope of protection of this disclosure.

[0029] See next Figure 2 , Figure 2 This is a structural schematic diagram of the first splitter according to the present disclosure. In some optional implementations of some embodiments, the first splitter 31 may further include a first air inlet 311, a first air storage chamber 312, and a plurality of first air outlets 313 connected in communication. In the assembled state, the first air inlet 311 is connected to the main air supply line 21 ( Figure 1 As shown in the diagram, each of the first air outlets 313 is connected to one of the aforementioned air delivery branches. The first gas storage chamber 312 stores a certain amount of gas to maintain gas pressure. A filter may also be provided in the first gas storage chamber 312 to filter impurities in the gas. Furthermore, a water-absorbing component may be provided in the first gas storage chamber to absorb moisture in the aforementioned air delivery branch. This effectively prevents moisture from entering the patient's mouth along with the gas, significantly improving the reliability of the multi-person ventilator. As an example, the water-absorbing component may be absorbent resin, cotton cloth, etc.

[0030] Similarly, the second distributor includes a second air outlet, a second air reservoir, and multiple second air inlets. In its assembled state, the second air outlet is connected to the main exhaust pipe, and each of the second air inlets is connected to one of the exhaust branch pipes. A disinfection spraying device is installed inside the second air reservoir, which sprays the reservoir for a preset time. This device disinfects the gas exhaled by the patient in the second air reservoir. For example, the disinfection spraying device may include a storage tank for storing disinfectant, and an outlet pipe connected to the storage tank, which extends into the second air reservoir. Furthermore, a valve may be installed on the outlet pipe. This valve opens for a predetermined time, sprays a predetermined amount of disinfectant, and then closes. It should be noted that the preset time can be set by those skilled in the art based on actual conditions. By spraying disinfectant into the second air reservoir, the patient's exhaled gas can be disinfected. This prevents germs carried in the patient's exhaled breath from spreading into the air and infecting medical staff or other patients. Therefore, it improves the safety of using ventilators for multiple patients.

[0031] In some optional implementations, a one-way valve is provided on the gas supply branch line to restrict the gas flow direction and prevent gas backflow. Furthermore, a filter is provided on the gas supply branch line to remove impurities or bacteria from the gas. Gas flow meters can also be installed on both the gas supply and exhaust branch lines to monitor the gas flow rates. By monitoring the gas flow rates in the gas supply and exhaust branch lines, the inhaled and exhaled gas flow rates of the patient can be monitored. This helps medical personnel understand the patient's breathing status and adjust the gas flow rate in the gas supply branch line accordingly.

[0032] In some optional implementations, a flow regulating component may be provided on the gas delivery branch line. This flow regulating component is used to adjust the gas flow rate in the gas delivery branch line according to the gas flow rate monitored by the gas flow meter. The flow regulating component includes at least one of the following: a Hoffman clamp, a peristaltic pump, and a flow regulating valve. Specifically, the gas flow rate in the gas delivery branch line can be adjusted by manually adjusting the Hoffman clamp to compress the gas delivery branch line. Similarly, the gas flow rate in the gas delivery branch line can be adjusted by adjusting the degree of compression of the gas delivery branch line by the rotor of the peristaltic pump.

[0033] In some optional implementations of the embodiments, the multi-person ventilator further includes a flow controller, the flow controller, the gas flow meter, and the flow regulating component are communicatively connected. In response to a discrepancy between the gas flow value received from the gas flow meter and a preset flow value, the flow controller controls the flow regulating component to adjust the gas flow in the gas delivery branch. The preset flow value is obtained by analyzing the patient's age using an artificial intelligence chip included in the flow controller. The machine learning model carried by the artificial intelligence chip has been trained using a training sample set.

[0034] As an example, a machine learning model can be obtained by performing the following training steps based on a training sample set: inputting the age of the sample patients of at least one training sample in the training sample set into the initial machine learning model to obtain a preset flow value corresponding to that age; comparing the preset flow value corresponding to the age of each sample patient in the at least one training sample with the corresponding sample preset flow value; determining the prediction accuracy of the initial machine learning model based on the comparison result; determining whether the prediction accuracy is greater than a preset accuracy threshold; in response to determining that the accuracy is greater than the preset accuracy threshold, using the initial machine learning model as the trained machine learning model; in response to determining that the accuracy is not greater than the preset accuracy threshold, adjusting the parameters of the initial machine learning model, and using unused training samples to form a training sample set, using the adjusted initial machine learning model as the initial machine learning model, and performing the above training steps again.

[0035] Understandably, after the above training, the machine learning model can be used to represent the correspondence between a patient's age and a preset flow rate value. The aforementioned machine learning model can be a convolutional neural network model.

[0036] The aforementioned flow controller can automatically adjust the gas flow rate in each delivery bronchus according to the age of each patient, ensuring that the gas flow rate matches the patient's needs. This improves the targeted nature of the multi-patient ventilator, eliminates the need for medical staff to manually adjust the gas flow rate in each delivery bronchus, and increases the operational efficiency of the multi-patient ventilator.

[0037] The multi-person ventilator disclosed in some embodiments of this invention firstly incorporates a water-absorbing component in the first gas storage chamber, enabling the chamber to absorb moisture from the tubing. This effectively prevents moisture from entering the patient's mouth along with the gas, significantly improving the reliability of the multi-person ventilator.

[0038] Furthermore, the disinfection spray device installed in the second gas storage chamber can disinfect the patient's exhaled air. This prevents pathogens carried in the patient's exhaled air from spreading into the air and infecting medical staff or other patients. Therefore, it improves the safety of the aforementioned multi-person ventilator.

[0039] Furthermore, by installing a check valve on each gas delivery branch line, the problem of gas backflow can be avoided. In addition, by installing a gas flow meter and flow regulating component on each of the above-mentioned gas delivery branches line, the gas flow rate in each gas delivery branch line can be adjusted according to the condition of each patient when gas is supplied to multiple patients simultaneously.

[0040] Finally, through the aforementioned flow controller, the multi-patient ventilator can automatically adjust the gas flow rate in each delivery bronchus according to the age of each patient, ensuring that the gas flow rate matches the patient's needs. This improves the targeted nature of the multi-patient ventilator, eliminates the need for medical staff to manually adjust the gas flow rate in each delivery bronchus, and increases the overall efficiency of the multi-patient ventilator.

[0041] The above description is merely a preferred embodiment of this disclosure and an explanation of the technical principles employed. Those skilled in the art should understand that the scope of the invention involved in this disclosure is not limited to technical solutions formed by specific combinations of the above-described technical features, but should also cover other technical solutions formed by arbitrary combinations of the above-described technical features or their equivalents without departing from the inventive concept. For example, technical solutions formed by substituting the above-described features with (but not limited to) technical features disclosed in this disclosure that have similar functions.
