Description

Technical Field

[0001] The present disclosure relates to the technical field of medical devices, and in particular to a detection device for a ventilator. Background Art

[0002] A ventilator is a vital medical device that can prevent and treat respiratory failure, reduce complications, and save and prolong patients' lives. In modern clinical medicine, as an effective means of artificially replacing spontaneous ventilation, ventilators are widely used for respiratory failure caused by various causes, anesthesia and respiratory management during major surgery, and emergency resuscitation. During the development and production of ventilators, ventilator testing is essential and crucial to their proper function.

[0003] The relevant ventilator testing process includes structures such as external gas supply equipment, trachea, pressure reducing valve, and float flowmeter. Specifically, the external gas supply equipment is connected to the pressure reducing valve, float flowmeter, and ventilator via the trachea, and gas is output to the trachea through the external gas supply equipment to achieve leak testing of the ventilator. Among them, the external gas supply equipment is usually an air compressor or gas cylinder. The air compressor or gas cylinder outputs high-pressure gas, which is reduced to the gas pressure required for leak testing through the pressure reducing valve. The ventilator is tested by observing the float flowmeter.

[0004] However, the ventilator has multiple air path modules, and the air pipe can only be connected to the external air supply equipment and one of the air path modules of the ventilator. It is impossible to perform synchronous detection on multiple air path modules of the ventilator. At the same time, it is impossible to detect multiple ventilators. During the detection process of the ventilator, the air path modules of the ventilators to be detected need to be connected in sequence, and the detection efficiency is low. Utility Model Content

[0052] An embodiment of the present disclosure provides a detection device for a ventilator, comprising a housing, an air inlet interface, multiple air outlet interfaces, an air pipe, a switch, a pressure regulating valve, and a first pressure gauge. An air inlet interface is provided on the outer shell for connecting to an external air supply device; a plurality of air outlet interfaces are provided on the outer shell for respectively connecting to a plurality of air circuit modules of the ventilator; the trachea includes a main air pipe and a plurality of branch air pipes, the first end of the main air pipe is connected to the air inlet interface, the first ends of the plurality of branch air pipes are all connected to the second end of the main air pipe, and the second ends of the plurality of branch air pipes are respectively connected to the plurality of air outlet interfaces one by one; the switch includes a main control switch and a plurality of sub-control switches, the main control switch is connected to the main air pipe, and the plurality of sub-control switches are respectively connected to one of the plurality of branch air pipes; the pressure regulating valve is connected to the main air pipe, and is provided on a side of the main control switch close to the first end of the main air pipe, for adjusting the pressure of the gas input in the main air pipe to a preset pressure; the first pressure gauge is connected to the main air pipe, and is provided on a side of the main control switch close to the second end of the main air pipe, for detecting the gas pressure in the plurality of branch air pipes and detecting the plurality of air circuit modules of the ventilator. The detection device for a ventilator disclosed in the present invention can synchronously detect multiple air path modules of the ventilator or multiple ventilators during the detection process of the ventilator, thereby improving the detection efficiency of the ventilator.

[0053] According to one aspect of the present disclosure, a detection device 1 for a ventilator is provided, comprising a housing 101, an air inlet interface 102, a plurality of air outlet interfaces 103, an air pipe 104, a switch 105, a pressure regulating valve 106, and a first pressure gauge 107. The housing 101 serves as a protective structure for the detection device 1. On the one hand, it can prevent external structural damage from damaging other components inside the housing 101, thereby allowing the detection device 1 to be used normally and improving the service life of the detection device 1. On the other hand, by arranging structures such as the air inlet interface 102, the air outlet interface 103, the switch 105, the pressure regulating valve 106, and the first pressure gauge 107 on the housing 101, all components required for the detection device 1 are integrated on the housing 101, and the air pipe 104 is also already connected inside the housing 101, eliminating the need to repeatedly connect each component each time. This can simplify the detection process for the operator, facilitate the storage of each component, and facilitate the operator's operation and storage.

[0054] Among them, the air inlet interface 102 is arranged on the shell 101, which is used to connect to the external air supply equipment 2; multiple air outlet interfaces 103 are arranged on the shell 101, which are used to connect to multiple air path modules of the ventilator respectively; the trachea 104 includes a main air pipe 1041 and multiple branch air pipes 1042, the first end of the main air pipe 1041 is connected to the air inlet interface 102, the first ends of the multiple branch air pipes 1042 are all connected to the second end of the main air pipe 1041, and the second ends of the multiple branch air pipes 1042 are respectively connected to the multiple air outlet interfaces 103 one by one; the switch 105 includes a main control switch 1051 and multiple sub-control switches 1052, the main control switch 1051 is connected to the main air pipe 1041, and the multiple sub-control switches 1052 are respectively connected to one of the multiple branch air pipes 1042.

[0055] Since the trachea 104 includes a main trachea 1041 and multiple branch trachea 1042, the switch 105 includes a main control switch 1051 and multiple sub-control switches 1052, the main control switch 1051 is connected to the main trachea 1041, and the multiple sub-control switches 1052 are respectively connected to one of the multiple branch trachea 1042. On the one hand, the main control switch 1051 and the sub-control switch 1052 can be used to control the on and off of the main trachea 1041 and the branch trachea 1042 respectively, so as to avoid high-pressure gas from harming the operator and improve the safety of the operator during the ventilator testing process; on the other hand, since the multiple branch trachea 1042 are connected to the multiple gas outlet interfaces 103 one by one and then connected to the multiple gas path modules of the ventilator, the on and off of the multiple switches 105 can be controlled to realize the detection of the multiple gas path modules. During the detection process of the ventilator, the multiple gas path modules of the ventilator or multiple ventilators can be synchronously detected, which can improve the detection efficiency of the ventilator.

[0056] Furthermore, the pressure regulating valve 106 is connected to the main air pipe 1041 and is arranged on the side of the main control switch 1051 close to the first end of the main air pipe 1041, and is used to adjust the gas pressure input into the main air pipe 1041 to a preset pressure; the first pressure gauge 107 is connected to the main air pipe 1041 and is arranged on the side of the main control switch 1051 close to the second end of the main air pipe 1041, and is used to detect multiple air path modules of the ventilator by detecting the gas pressure in multiple branch air pipes 1042.

[0057] Since the pressure regulating valve 106 is connected to the main gas pipe 1041 and is arranged on the side of the main control switch 1051 near the first end of the main gas pipe 1041, and the first pressure gauge 107 is connected to the main gas pipe 1041 and is arranged on the side of the main control switch 1051 near the second end of the main gas pipe 1041, on the one hand, the pressure regulating valve 106 can be used to regulate the high-pressure gas provided by the external gas supply device 2, so that the regulated air pressure meets the detection requirements of the ventilator, which can improve the accuracy of the ventilator detection process; on the other hand, the first pressure gauge 107 can be used to display the gas pressure in the gas pipe 104 after the pressure regulating valve 106 is regulated in real time, which can prevent the gas pressure regulated by the pressure regulating valve 106 from being too high and damaging the components in the detection device 1, and at the same time, it can improve the accuracy of the operator during the detection process. In addition, the gas pressure in the gas pipe 104 at this time can be intuitively judged by the first pressure gauge 107, thereby facilitating the operator's operation.

[0058] Similarly, since the first pressure gauge 107 is connected to the main air pipe 1041 and is arranged on the side of the main control switch 1051 close to the second end of the main air pipe 1041, and the first ends of the multiple branch air pipes 1042 are all connected to the second end of the main air pipe 1041, the second ends of the multiple branch air pipes 1042 are respectively connected to the multiple air outlet interfaces 103 one by one. The first pressure gauge 107 can be used to detect the gas pressure in the multiple branch air pipes 1042 and detect the multiple air path modules of the ventilator, thereby supporting the simultaneous pressure adjustment of multiple air path modules, and the detection process of multiple air path modules can be carried out synchronously, which can improve the detection efficiency of the ventilator.

[0059] The following is a detailed description of each part of the detection device 1 for a ventilator:

[0060] In an exemplary embodiment of the present disclosure, the number of branch air pipes 1042 is M, where M is a positive integer, and the numbers of the branch air pipes 1042 are M1, M2, ..., M. i-1 、M i , 3≤i; the number of sub-control switches 1052 is K, K is a positive integer, and the sub-control switches 1052 are numbered K1, K2...K i-1 , K i , 3≤i; among them, number is K i The sub-control switch 1052 is connected to the M i Branch trachea 1042, numbered M i The first end of the branch airway 1042 is connected to the second end of the main airway 1041.

[0061] Specifically, since the number is K i The sub-control switch 1052 is connected to the M iBranch trachea 1042, numbered M i The first end of the branch air pipe 1042 is connected to the second end of the main air pipe 1041, so that the sub-control switch 1052 can correspond one to one with the branch air pipe 1042. On the one hand, the on and off of multiple sub-control switches 1052 can be synchronously controlled to realize the detection of multiple branch air pipes 1042, and then the detection of multiple different air path modules can be realized. The operator can directly realize the synchronous operation of multiple air path modules by controlling the corresponding sub-control switches 1052, which can simplify the operator's operation and at the same time improve the efficiency of detecting multiple air path modules.

[0062] In addition, since multiple sub-control switches 1052 correspond one-to-one to multiple branch air pipes 1042, the operator can inspect the branch air pipes 1042 and the air path modules that need to be inspected according to needs, making the operator's inspection selective.

[0063] In an exemplary embodiment of the present disclosure, the detection device 1 further includes a plurality of adapter interfaces, the number of which is N, where N is a positive integer, and the numbers of the adapter interfaces are N1, N2, ..., N. i-1 、N i , 3≤i; the air inlet of the adapter interface numbered N1 is connected to the second end of the main air pipe 1041, and the first air outlet of the adapter interface numbered N1 is connected to the first end of the branch air pipe 1042 numbered M1; the air inlet of the adapter interface numbered N2 is connected to the second air outlet of the adapter interface numbered N1, and the first air outlet of the adapter interface numbered N2 is connected to the first end of the branch air pipe 1042 numbered M2; i-1 The air inlet of the adapter is connected to the i-2 The second outlet of the adapter interface is numbered N i-1 The first air outlet of the adapter interface is connected to the i-1 The first end of the branch trachea 1042 is numbered N i-1 The second air outlet of the adapter interface is connected to the i The first end of the branch airway 1042.

[0064] Specifically, since the detection device 1 also includes multiple adapter interfaces, the connection between multiple branch air pipes 1042 is realized through multiple adapter interfaces. On the one hand, it can avoid directly leading out multiple connection ports from the main air pipe 1041. In the process of detecting multiple branch air pipes 1042, greater pressure is caused to the multiple connection ports of the main air pipe 1041, thereby affecting the life of the main air pipe 1041, and the safety and stability of the detection device 1 during operation can be improved; on the other hand, it can avoid directly leading out multiple connection ports from the main air pipe 1041. In the process of detecting multiple branch air pipes 1042, the multiple branch air pipes 1042 affect each other, resulting in inaccurate detection between the branch air pipes 1042, and the accuracy of the detection device 1 during the detection process can be improved.

[0065] Similarly, since the number is N i-1 The air inlet of the adapter is connected to the i-2 The second outlet of the adapter interface is numbered N i-1 The first air outlet of the adapter interface is connected to the i-1 The first end of the branch trachea 1042 is numbered N i-1 The second air outlet of the adapter interface is connected to the i The first end of the branch air pipe 1042 can avoid causing greater pressure and interference to the branch air pipe 1042, thereby improving the stability and accuracy of each branch air pipe 1042, and further improving the overall stability and accuracy of the detection device 1.

[0066] In one exemplary embodiment of the present disclosure, the adapter interface is a three-way valve. Specifically, because the adapter interface is a three-way valve, compared to using multiple one-way valves to achieve similar functions, the three-way valve design is more compact and can occupy less space, thereby reducing the complexity and installation cost of the air pipe 104. It can also reduce the overall size of the detection device 1, making the detection device 1 more lightweight. In addition, the three-way valve generally has a simple structure and operation method, is easy to maintain and operate, and thus facilitates the control of the flow and direction of the gas in the air pipe 104.

[0067] In an exemplary embodiment of the present disclosure, the detection device 1 also includes a detection component 108, including a detection interface 1081, a detection air pipe 1082 and a second pressure gauge 1083, the detection air pipe 1082 is connected to the detection interface 1081 and the second pressure gauge 1083, and the detection interface 1081 is connected to the main air pipe 1041 or any branch air pipe 1042 for detecting the gas pressure in the main air pipe 1041 or the branch air pipe 1042.

[0068] Specifically, since the detection air pipe 1082 is connected to the detection interface 1081 and the second pressure gauge 1083, and the detection interface 1081 is connected to the main air pipe 1041 or any branch air pipe 1042, the gas pressure in the air pipe 104 can be secondarily detected after the detection device 1 is connected to the external gas supply device 2 and the air circuit module, thereby improving the accuracy of the gas pressure detection in the air pipe 104. In addition, when multiple air circuit modules are tested through multiple branch air pipes 1042, the multiple branch air pipes 1042 will change the initial gas pressure in the main air pipe 1041 due to the diversion effect, so that the gas pressure in the branch air pipe 1042 to be tested can be secondarily detected and verified through the second pressure detection gauge, thereby improving the accuracy of the detection device 1.

[0069] In an exemplary embodiment of the present disclosure, a detection interface 1081 is connected between the pressure regulating valve 106 and the main control switch 1051 and is used to detect the gas pressure within the main gas pipe 1041 after pressure regulation by the pressure regulating valve 106. Specifically, if the regulated gas pressure is still too high after the pressure regulating valve 106 regulates the high-pressure gas transmitted by the gas supply device 2, it may damage subsequent structures such as the main control switch 1051. Therefore, a second pressure gauge 1083 pre-detects the gas pressure within the main gas pipe 1041 after pressure regulation by the pressure regulating valve 106. Therefore, if the pressure regulated by the pressure regulating valve 106 does not meet the expected pressure, the pressure regulating valve 106 can be used to re-regulate the gas pressure within the main gas pipe 1041. This improves the accuracy of the pressure regulating valve 106's regulation and prevents damage to other components of the detection device 1, thereby improving the safety of the detection device 1. Furthermore, it provides a preliminary reading for subsequent pressure testing, thereby facilitating the operator's operation.

[0070] In an exemplary embodiment of the present disclosure, the detection device 1 further includes a flow regulating valve 109 connected to one of the branch gas pipes 1042 for regulating the gas flow within the branch gas pipe 1042. Specifically, since the flow regulating valve 109 is connected to one of the branch gas pipes 1042 for regulating the gas flow within the branch gas pipe 1042, the operator can output gas at a required flow rate according to detection requirements, thereby making the detection process diversified and targeted, thereby enabling detection of different performances of the gas path module.

[0071] In an exemplary embodiment of the present disclosure, the detection device 1 further includes a plurality of flow meters, respectively connected to the main air pipe 1041 and the branch air pipe 1042, for detecting the flow rates of the main air pipe 1041 and the branch air pipe 1042. Specifically, since the plurality of flow meters are respectively connected to the main air pipe 1041 and the branch air pipe 1042 for detecting the flow rates of the main air pipe 1041 and the branch air pipe 1042, the flow meters can be used to perform leakage detection on the main air pipe 1041 and the branch air pipe 1042, thereby achieving leakage detection of the gas circuit module, thereby meeting different detection requirements for the gas circuit module, and thus making the gas circuit module more reliable during use.

[0072] In an exemplary embodiment of the present disclosure, the detection device 1 further includes a one-way valve 110, which is connected to the main gas pipe 1041 and disposed between the pressure regulating valve 106 and the main control switch 1051. Specifically, since the one-way valve 110 is connected to the main gas pipe 1041 and disposed between the pressure regulating valve 106 and the main control switch 1051, it can effectively prevent the reverse flow of gas in the main gas pipe 1041, thereby ensuring the smooth progress and safety of the detection process. In addition, the one-way valve 110 can maintain the gas pressure under the condition of forward gas flow, thereby ensuring the stability of the gas pressure in the gas pipe 104, thereby improving the accuracy of the detection process of the detection device 1.

[0073] In an exemplary embodiment of the present disclosure, at the same time, two sub-control switches 1052 are opened simultaneously. Specifically, since the gas pressure adjusted by the pressure regulating valve 106 meets the pressure required for the detection of the air circuit module of the ventilator, when multiple air circuit modules are synchronously detected, multiple branch air pipes 1042 will evenly divide the gas pressure in the main air pipe 1041. When too many sub-control switches 1052 are opened to synchronously control the detection of too many air circuit modules, the detection processes of multiple air circuit modules will affect each other, resulting in inaccurate detection. At the same time, when the two sub-control switches 1052 are opened simultaneously, the gas pressure in the two branch air pipes 1042 can meet the detection requirements of the air circuit module, thereby further improving the accuracy of the synchronous detection process of multiple air circuit modules.

[0074] In an exemplary embodiment of the present disclosure, there are multiple ventilators, and the multiple air outlet interfaces 103 are respectively connected to the multiple air circuit modules of the multiple ventilators.
