Description

Technical Field

[0001] The present invention relates to the technical field of respiratory medical equipment, and in particular to an integrated respiratory analysis and respiratory function training device capable of preventing cross infection. Background Art

[0002] As a place where medical resources are concentrated, hospitals need to meet the rehabilitation needs of a large number of patients. Shared respiratory rehabilitation exercise devices can ensure that limited medical resources are maximized to reduce the hospital's procurement and maintenance costs. Secondly, shared equipment can adapt to the rehabilitation needs of different patients by flexibly adjusting the equipment settings and parameters to achieve the best treatment effect.

[0003] Because shared equipment carries the risk of cross-infection, each patient using a respiratory rehabilitation exercise device must disinfect it after each use, ensuring thorough disinfection after each use. However, when frequently changing patients, the residual liquid and particles in the breathing tube cannot be disinfected in a timely manner during the process of changing mouthpieces for respiratory exercises, resulting in residual pathogens in the breathing tube. During the patient's breathing process, these residual pathogens enter the respiratory tract and pose an infection risk. Therefore, the present invention provides an all-in-one respiratory analysis and respiratory function training device that prevents cross-infection, reducing the risk of cross-infection during continuous use by patients. Summary of the Invention

[0004] To solve the above problems, the present invention provides an all-in-one respiratory analysis and respiratory function training device that prevents cross infection, which is convenient for patients to use and reduces the risk of cross infection during continuous use by patients.

[0005] To achieve the above objectives, the present invention provides a technical solution as follows: an integrated respiratory analysis and respiratory function training device for preventing cross infection, comprising a respiratory device main unit for performing respiratory training, a breathing tube connected to one side of the respiratory device main unit for guiding a patient's exhaled gas, a respiratory analysis component connected to the breathing tube within the respiratory device main unit, and configured to analyze the composition of the patient's exhaled gas; a contact piece detachably connected to an end of the breathing tube remote from the respiratory device main unit for contact with the patient's oral cavity for breathing; Several gas delivery pipes are fixedly connected to the breathing tube, and the gas delivery pipes are respectively connected to the breathing device host and the breathing analysis component; An airway switching mechanism for switching the connection status of the gas delivery pipeline is provided at one end of the breathing tube away from the main body of the breathing apparatus; The airway conversion mechanism is provided with a detection mechanism for detecting the ventilation condition in the breathing tube. The detection mechanism is electrically connected to a processing panel, and the processing panel is electrically connected to a display mechanism for displaying the ventilation condition in the breathing tube.

[0006] Furthermore, the airway conversion mechanism includes a connecting block fixedly connected to the breathing tube, a semicircular arc-shaped shielding plate is provided in the connecting block, a rotating shaft is fixedly connected to one side of the shielding plate, and the rotating shaft rotates in cooperation with the connecting block; and the connecting block is also provided with a plurality of rotating cavities, and fan blades are provided at both ends of the rotating shaft for pushing the shielding plate to rotate clockwise or counterclockwise, and the fan blades are located in the rotating cavities and slide in cooperation with the connecting block; A disinfection tube for conveying disinfectant is also provided in the breathing tube. The disinfection tube includes a first tube and a second tube. The first tube is connected to a first solenoid valve, and the second tube is connected to a second solenoid valve. The first tube and the second tube are respectively connected to the rotating chamber. A slider is slidably fitted in the connecting block, and an exchange port corresponding to the gas delivery pipeline is provided on the slider; a control channel is also provided in the slider, and the control channel is connected to the exchange port; a conductive block is provided in the control channel, and a second spring is provided between the conductive block and the contact block, and the conductive block is electrically connected to the processing panel; switches are provided on both sides of the control channel, and the switches are fixedly connected to the slider, and the switches are respectively connected to the first solenoid valve and the second solenoid valve, wherein the switch electrically connected to the first solenoid valve is the first switch, and the switch electrically connected to the second solenoid valve is the second switch; When the conductive block contacts the first switch, the first solenoid valve is activated; when the conductive block is separated from the second switch, the first solenoid valve is in a normal state.

[0007] Furthermore, a magnet layer for fixing the shielding plate is fixedly connected to one side of the connecting block close to the shielding plate.

[0008] Furthermore, the contact piece is provided with a slot that slides with the rotating shaft, a first spring is provided between the side of the slider away from the breathing tube and the connecting block, and a plurality of deformable rubber layers are fixedly connected to the center of the slider, and the rubber layer is used to divide the interior of the connecting block.

[0009] Furthermore, a friction layer is fixedly connected to the inside of the connecting block, a number of friction lines are fixedly connected to the friction layer, and a number of clamping blocks are fixedly connected to the inner wall of the contact piece. When the contact piece moves to the deepest part of the connecting block, the clamping blocks abut against the shielding plate.

[0010] Furthermore, the first tube is connected to the gas delivery pipeline on one side, and the second tube is connected to the gas delivery pipeline on the other side; An extrusion cavity is formed between the first tube and the second tube and is connected to the gas delivery pipeline. An extrusion block is slidably fitted in the extrusion cavity. The extrusion block is located between the first tube and the gas delivery pipeline, and the extrusion block is also located between the second tube and the gas delivery pipeline. When the squeezing block is pushed by the patient's respiratory gas to move to the farthest point of the gas delivery tube, the squeezing block abuts against the first tube or the second tube.

Both the first drain pipe and the second drain pipe are connected to a number of drainage holes connected to the outside world. When the first solenoid valve is started, the baffle plate rotates clockwise, and the first drain pipe is located on the side of the baffle plate close to the connecting block.

[0012] Furthermore, the detection mechanism includes a plurality of pressure sensors for detecting real-time pressure data when the extrusion block contacts the disinfection tube, and the pressure sensors are located between the extrusion block and the disinfection tube; The processing panel is used to compare the real-time pressure data with the set standard value. If the real-time pressure data is greater than the standard value, a normal ventilation instruction is sent to the display unit; if the real-time pressure data is less than the standard value, an abnormal ventilation instruction is sent to the display unit.

[0013] Furthermore, an outer conduit communicating with the outer wall of the connecting block is opened in the connecting block, and the outer conduit is communicated with the rotating cavity.

[0014] Furthermore, a one-way valve is connected to the side of the control channel away from the conductive block. The one-way valve can only allow the gas inside the control channel to flow to the outside. Pressure relief ports are provided on both sides of the connecting block. When the first spring is in a normal state, the slider is parallel to the pressure relief port.

[0015] The above scheme has the following beneficial effects: 1. This solution uses sliding-fit contacts and connecting blocks to facilitate patient docking or disassembly of the contacts with the breathing tube, facilitating ease of use and meeting the continuous use needs of different patients.

[0016] 2. This solution uses a testing agency to confirm whether the patient's breathing intensity meets the standard during breathing exercises, so as to issue corresponding reminders and enable the patient to make adjustments and repeat measurements to ensure data accuracy.

[0017] 3. This solution uses the changes in the movement of the conductive block caused by the patient's breathing to automatically control the corresponding first solenoid valve or the second solenoid valve to start, and to automatically control the baffle to flip, so as to reduce cross-contact between different gas delivery pipelines and reduce the risk of cross-infection.

Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0024] The following is further described in detail through specific implementation methods: Example 1:

[0025] As attached Figures 1 to 11 The figure shows an integrated respiratory analysis and respiratory function training device for preventing cross-infection. The device includes a main unit 1 for respiratory training. The main unit 1 is conventional and will not be described in detail in this embodiment. A breathing tube 2 for guiding a patient's exhaled gas is connected to one side of the main unit 1. In this embodiment, the breathing tube 2 is a retractable bellows. The main unit 1 also includes a respiratory analysis component (not shown) connected to the breathing tube 2. The respiratory analysis component is used to detect and analyze the components of the patient's exhaled gas. The respiratory analysis component is conventional and will not be described in detail in this embodiment. For example, a model of the Quinton series (SC / DP / H2+ / H2) exhaled gas analyzer is provided. A contact member 4, such as a mouthpiece or respiratory mask, is detachably connected to the end of the breathing tube 2 away from the main unit 1. The contact member 4 is designed to contact the patient's mouth for breathing.

[0026] Several gas delivery pipes 21 are clamped in the breathing tube 2, and the gas delivery pipes 21 are respectively connected to the breathing device host 1 and the breathing analysis component.

[0027] An airway conversion mechanism is provided at the end of the breathing tube 2 away from the main unit 1 of the breathing device, for converting the connectivity of the gas delivery pipe 21; the airway conversion mechanism includes a connecting block 3 bonded to the breathing tube 2, a semicircular arc-shaped baffle 6 is provided in the connecting block 3, a rotating shaft 61 is welded to one side of the baffle 6, and the rotating shaft 61 rotates in cooperation with the connecting block 3; and a plurality of rotating cavities are also provided on the connecting block 3, and fan blades 62 are respectively provided at both ends of the rotating shaft 61 for pushing the baffle 6 to rotate clockwise or counterclockwise, the fan blades 62 are located in the rotating cavity, and the fan blades 62 slide in cooperation with the connecting block 3.

[0028] A disinfection tube 5 for conveying disinfectant is also provided in the breathing tube 2. The disinfection tube 5 includes a first tube 51 and a second tube 52. The first tube 51 is connected to a first solenoid valve 53, and the second tube 52 is connected to a second solenoid valve 54. The first tube 51 and the second tube 52 are respectively connected to the rotating chamber. In this embodiment, the first tube 51 is used to push the fan blades 62 to drive the baffle 6 to rotate clockwise, and the second tube 52 is used to push the fan blades 62 to drive the baffle 6 to rotate counterclockwise.

[0029] A slider 31 slidably engages within the connection block 3. The slider 31 defines an exchange port corresponding to the gas delivery pipe 21. The slider 31 also defines a control channel, which communicates with the exchange port. A conductive block 35 is positioned within the control channel, with a second spring 34 positioned between the conductive block 35 and the contact block. One end of the second spring 34 is fixedly connected to the conductive block 35, while the other end of the second spring 34 is fixedly connected to the slider 31. The conductive block 35 is electrically connected to the processing panel. Switches 36 are positioned on either side of the control channel, fixedly connected to the slider 31. These switches 36 communicate with a first solenoid valve 53 and a second solenoid valve 54, respectively. The switch 36 electrically connected to the first solenoid valve 53 is the first switch 36, while the switch 36 electrically connected to the second solenoid valve 54 is the second switch 36. The first and second solenoid valves 53 and 54 are normally closed. When the conductive block 35 contacts the first switch 36, the first solenoid valve 53 is actuated. When the conductive block 35 separates from the second switch 36, the first solenoid valve 53 is in its normal state.

[0030] The contact member 4 is provided with a slot that slides with the rotating shaft 61 . A first spring 32 is provided between the side of the slider 31 away from the breathing tube 2 and the connecting block 3 . A plurality of deformable rubber layers 7 are fixedly connected to the center of the slider 31 . The rubber layer 7 is used to divide the interior of the connecting block 3 .

[0031] The airway conversion mechanism is provided with a detection mechanism for detecting the ventilation condition in the breathing tube 2. The detection mechanism is electrically connected to a processing panel, and the processing panel is electrically connected to a display mechanism 11 for displaying the ventilation condition in the breathing tube 2. The display mechanism 11 is located above the respiratory device host 1.

[0032] The detection mechanism includes several pressure sensors (not shown in the figure) for detecting real-time pressure data when the extrusion block 22 contacts the disinfection tube 5. The pressure sensors are located between the extrusion block 22 and the disinfection tube 5. The processing panel is used to compare the real-time pressure data with the set standard value. If the real-time pressure data is greater than the standard value, a normal ventilation instruction is sent to the display mechanism 11; if the real-time pressure data is less than the standard value, an abnormal ventilation instruction is sent to the display mechanism 11.

[0033] For example, the force change when the patient's exhaled gas pushes the squeezing block 22 can be used to confirm whether the patient's breathing intensity meets the standard during breathing exercises, so as to give corresponding reminders, enable the patient to make adjustments and repeat measurements to ensure data accuracy.

[0034] The specific implementation process is as follows: First, during the installation of the contact member 4, align the circular opening of the contact member 4 with the connecting block 3 and press the contact member 4 into the connecting block 3 until the contact member 4 is firmly seated, thereby securing the contact member 4 to the connecting block 3. In this embodiment, the contact member 4 also has an L-shaped groove. Rotating the contact member 4 causes the L-shaped groove to align with the rotating shaft 61, thereby improving the installation stability of the contact member 4.

[0035] During the detection process, the shielding plate 6 is flipped to block or leak a gas delivery pipe 21, so as to switch the gas delivery pipe 21. At the same time, during the flipping process of the shielding plate 6, the contact between the shielding plate 6 and the gas exhaled by the previous patient is converted to reduce the contact between different patients during use, so as to reduce the risk of cross infection.

[0036] During the patient's breathing training, the patient's gas is used to push the conductive block 35 to overcome the resistance of the second spring 34 and move, so that the conductive block 35 contacts the switch 36 to control the corresponding first solenoid valve 53 or the second solenoid valve 54 to open, so that the disinfectant in the disinfection tube 5 enters the rotating chamber to push the baffle 6 to rotate, thereby realizing the flipping and switching of the baffle 6.

[0037] When the slider 31 is pushed by the contact piece 4, the first spring 32 is stretched by the movement of the slider 31. After the contact piece 4 is removed, the stretching force of the first spring 32 is used to drive the slider 31 to reset, so as to realize the automatic reset of the slider 31; and the stretched spring facilitates the push of the contact piece 4 to pop out, so as to facilitate the separation of the contact piece 4 from the connecting block 3; at the same time, the slider 31 drives the rubber layers 7 on both sides to move, so as to maintain the division of the inside of the connecting block 3 by the rubber layer 7, ensure the isolation of adjacent gas delivery pipes 21, and thereby reduce the risk of cross infection.

[0038] Example 2:

[0039] The difference from Example 1 is that a magnet layer (not shown in the figure) for fixing the shielding plate 6 is fixedly connected to the side of the connecting block 3 close to the shielding plate 6 .

[0040] The specific implementation process is as follows: the shielding plate 6 is adsorbed and fixed by the magnet layer to improve the stability of the shielding plate 6 when it is not pushed by the fan blades 62, thereby improving the sealing effect of the shielding plate 6 on the gas delivery pipe 21 to reduce the risk of cross infection.

[0041] Example 3:

[0042] The difference from Example 2 is that a friction layer is fixedly connected to the inside of the connecting block 3, and a number of friction grooves are engraved on the friction layer. A number of clamping blocks 41 are integrally formed on the inner wall of the contact piece 4. When the contact piece 4 moves to the deepest part of the connecting block 3, the clamping blocks 41 abut against the baffle 6.

[0043] The specific implementation process is as follows: during the installation of the contact piece 4, the friction layer and friction lines are used to increase the friction area between the contact piece 4 and the connecting block 3 to improve the stability of the contact piece 4. At the same time, during the insertion of the contact piece 4, the blocking block 41 is used to support and limit the baffle plate 6 to improve the sealing effect of the baffle plate 6 on the inside of the connecting block 3, thereby preventing the patient from flipping the plate to open another gas delivery pipeline 21 during breathing exercises.

[0044] Example 4:

[0045] The difference from Example 3 is that the first tube 51 is connected to the gas delivery pipeline 21 on one side, and the second tube 52 is connected to the gas delivery pipeline 21 on the other side; An extrusion cavity is defined between the first tube 51 and the second tube 52 and is in communication with the gas delivery pipe 21. An extrusion block 22 is slidably fitted in the extrusion cavity. The extrusion block 22 is located between the first tube 51 and the gas delivery pipe 21, and is also located between the second tube 52 and the gas delivery pipe 21. When the squeezing block 22 is pushed by the patient's respiratory gas to move to the farthest point of the gas delivery tube, the squeezing block 22 abuts against the first tube 51 or the second tube 52 .

[0046] The specific implementation process is as follows: the gas generated by the patient during breathing exercises is used to push the squeezing block 22 to move, so that the squeezing block 22 squeezes the corresponding first tube 51 or the second tube 52, so that the first tube 51 or the second tube 52 of the gas delivery pipeline 21 that is currently connected is closed, so as to keep the first tube 51 and the second tube 52 on the other side unobstructed and continue to be disinfected, so as to achieve alternating disinfection of the gas delivery pipeline 21, without the need for additional waiting time for disinfection, thereby improving work efficiency and reducing the risk of infection for patients during continuous use.

[0047] Example 5:

[0048] The difference from Example 4 is that the rotating chamber is connected to a first drain pipe 63 and a second drain pipe 64 respectively. The rotating chamber connected to the first pipe 51 is connected to the first drain pipe 63, and the rotating chamber connected to the second pipe 52 is connected to the second drain pipe 64. The first drain pipe 63 and the second drain pipe 64 are respectively located on both sides of the baffle plate 6. The first drain pipe 63 and the second drain pipe 64 are both connected to a number of drainage holes connected to the outside world. When the first solenoid valve 53 is started, the baffle plate 6 rotates clockwise, and the first drain pipe 63 is located on the side of the baffle plate 6 close to the connecting block 3.

[0049] The specific implementation process is as follows: through the arrangement of the first drain pipe 63 and the second drain pipe 64, the baffle plate 6 is disinfected in advance according to the closing condition of the baffle plate 6, so as to reduce the residual pathogens on the baffle plate 6 when the patient comes into contact with the flipped baffle plate 6 during continuous use, thereby reducing the risk of cross infection; in this embodiment, taking the activation of the first solenoid valve 53 as an example, the activation of the first solenoid valve 53 is used to control the liquid sprayed from the first drain pipe 63 to form an auxiliary thrust, which facilitates the rotation of the baffle plate 6, and the disinfectant continuously sprayed from the first drain pipe 63 disinfects the surrounding environment as the baffle plate 6 rotates, so as to reduce the residual pathogens in the surrounding environment, thereby reducing the risk of cross infection during continuous use.

[0050] Example 6:

[0051] The difference from Example 5 is that an outer conduit 33 communicating with the outer wall of the connecting block 3 is further provided in the connecting block 3 , and the outer conduit 33 is communicated with the rotating chamber.

[0052] The specific implementation process is as follows: when the conductive block 35 controls the first solenoid valve 53 or the second solenoid valve 54 to start, the disinfection tube 5 is automatically opened to disinfect the outer wall of the breathing tube 2 to reduce the residual pathogens after the patient's hands come into contact with the breathing tube 2, thereby reducing the risk of subsequent contact between the patient and the residual pathogens.

[0053] Example 7:

[0054] The difference from Example 6 is that a one-way valve (not shown in the figure) is connected to the side of the control channel away from the conductive block 35. The one-way valve can only allow the gas inside the control channel to flow to the outside. Pressure relief ports 37 are provided on both sides of the connecting block 3. When the first spring 32 is in normal state, the slider 31 is parallel to the pressure relief port 37.

[0055] The specific implementation process is as follows: in the process of using the patient's exhaled gas to push the conductive block 35 to move, the one-way valve is used to control the gas flow direction inside the control channel to maintain a negative pressure difference between the control channel and the outside world, so that the conductive block 35 maintains contact with the switch 36 to control the start-up of the corresponding first solenoid valve 53 and the second solenoid valve 54, so that the first tube 51 or the second tube 52 is continuously opened until the slider 31 is connected to the pressure relief port 37, so that the control channel is connected to the pressure relief port 37, so as to use the disinfectant inside the first tube 51 or the second tube 52 to continuously push for flipping, thereby ensuring that the baffle 6 is flipped and rotated around the rotating shaft 61.

[0056] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will readily appreciate that other variations or modifications based on the above descriptions are possible. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
