TECHNICAL FIELD
[0001] The present application relates to the technical field of medical devices, and in particular to a self-adaptive oxygen inhalation system. BACKGROUND
[0002] Oxygen inhalation is to inhale oxygen, and oxygen therapy is mainly a method for relieving hypoxia. Appropriate oxygen inhalation is used to correct hypoxia, improve the level of arterial oxygen partial pressure and oxygen saturation, and promote metabolism, which is one of the important methods for auxiliary treatment of various diseases.
[0003] The oxygen inhalation machine is mainly matched with the medical central oxygen supply system, and is used for oxygen inhalation of emergency oxygen supply of medical units and hypoxia patients. Oxygen in the oxygen inhalation machine is delivered to the patient through the oxygen inhalation tube.
[0004] In the prior art, the oxygen inhalation equipment includes a gas bag oxygen inhalation device, a central control type bedside oxygen inhalation device, a breathing machine, and an oxygen inhalation machine storing oxygen, such as a household oxygen bag, a portable oxygen cylinder, a central oxygen supply system, etc. Among them, the oxygen inhalation machine is widely used due to its advantages of convenient movement and large oxygen storage capacity.
[0005] A medical nursing oxygen inhalation machine is disclosed in Chinese Patent No. CN108785811B, which comprises an oxygen inhalation machine body, a pipeline storage box is welded on one side of the oxygen inhalation machine body, the pipeline storage box is a hollow structure, and the side of the pipeline storage box away from the oxygen inhalation machine body is an open structure, a connecting air pipe is fixedly sleeved on the bottom side wall of the pipeline storage box, one end of the connecting air pipe deep into the oxygen inhalation machine body is in communication with the air inlet end of the oxygen inhalation machine body, and the other end of the connecting air pipe away from the oxygen inhalation machine body is fixedly sleeved with an isolation cover. The oxygen inhalation machine shown in the application is communicated with the above-mentioned central oxygen supply system, and neither of them can be moved.
[0006] During oxygen therapy, if a patient with independent ability needs to go out (for example, to the bathroom), the oxygen therapy process needs to be interrupted, and once the behavior of continuously supplying oxygen to the patient is interrupted, the oxygen therapy effect will be reduced. However, the equipment that can be moved together with the patient, such as the portable oxygen cylinder or the oxygen bag, cannot be compared with the oxygen inhalation machine in function, for example, the oxygen inhalation machine has the function of adjustable oxygen flow.
[0007] For patients with hypoxemia or at risk of hypoxemia, or non-hypoxemia patients who may benefit from oxygen therapy (such as gas poisoning of carbon monoxide), they will interrupt the oxygen therapy when they need to drink water or have urinary urgency and solve the above personal problems alone.
[0008] In the prior art, for patients in urgent need of oxygen inhalation, the medical transfer vehicle is used to carry the related oxygen inhalation equipment to provide oxygen inhalation equipment for the patients. Since the oxygen storage container and the oxygen flow adjusting equipment are relatively large in size, the physical strength of the medical staff is extremely tested during the carrying or accompanying process, and such equipment is not practical for patients who need to visit a doctor periodically for oxygen therapy. At the same time, even if the patient is at home for self-oxygen therapy, the portability and multifunctional use of the oxygen inhalation equipment are still not common characteristics. Based on this, the present application provides a self-adaptive oxygen inhalation device and a data processing system. The system can automatically follow the user while ensuring the oxygen storage capacity and the oxygen adjusting convenience of the equipment, so that the patient at home or during a visit can freely act based on his own needs during oxygen therapy.
[0009] In addition, on the one hand, there are differences in the understanding of those skilled in the art; on the other hand, a large number of literatures and patents have been studied by the applicant when making the present application, but due to the limited space, all the details and contents have not been listed in detail. However, this does not mean that the present application does not have these characteristics of the prior art. On the contrary, the present application already has all the characteristics of the prior art, and the applicant reserves the right to add relevant prior art in the background art. SUMMARY
[0010] In the prior art, oxygen inhalation is a periodic treatment method required by some chronic disease patients, especially chronic disease patients related to lung diseases, to maintain normal life activities. For example, patients with chronic obstructive pulmonary disease have weakened lung function, and their symptoms include dyspnea after exercise, chest tightness, palpitations, etc. Patients with chronic respiratory or lung diseases need regular oxygen therapy, for example, for patients with chronic lung disease with SPO2≤88% hypoxemia during sleep, obstructive sleep apnea syndrome, and obesity hypopnea syndrome combined with respiratory failure. Nighttime oxygen therapy effectively alleviates chest tightness, shortness of breath, and other symptoms caused by respiratory failure during sleep. Since the oxygen therapy process lasts for several hours, the patient can eat, change the resting position, and defecate during this process. When the patient is at home for oxygen therapy, the above actions require the patient to transfer the oxygen therapy equipment. In particular, when the patient suddenly needs to go to the bathroom during sleep at night, it is a very time-consuming behavior to move the oxygen therapy equipment or interrupt the oxygen therapy, which will increase the difficulty of the patient falling asleep again.
[0011] The present application provides a self-adaptive oxygen inhalation system. The system provided by the present application is suitable for providing one-to-one service for patients in need of oxygen therapy in hospitals, and is also suitable for providing oxygen therapy service for patients at home. The system includes a following unit and a remote control unit, as shown in Figure 1 Specifically, the following unit includes an oxygen supply unit module and an alarm module, as shown in Figure 2
[0012] The system comprises a detection module. Preferably, the detection module comprises a first part arranged on the following unit and a second part arranged on the patient's body. Based on the position information of the patient transmitted by the second part arranged on the patient's body, the remote control unit can generate the position information of the following unit. The remote control unit can determine the position of the patient based on the report of the positioning information of the second part. The detection module comprises an image acquisition component. The second part comprises an image acquisition component. The detection module comprises a first part arranged on the following unit and a second part arranged on the patient's body, based on the position information of the patient transmitted by the second part arranged on the patient's body at a first time node, the remote control unit generates the position information of the following unit at a second time node, wherein the position of the following unit following the movement of the patient at least partially coincides with the position of the patient. The first time node is earlier than the second time node. The time interval between adjacent time nodes is the same. The length of the time interval can be manually set based on external monitoring needs. For example, the time interval can be 1s. The position information refers to the information used to characterize the current position of the patient or the following unit, and the remote control unit can determine the position of the patient or the following unit in the environment based on the position information. The position information can be coordinates with wgs84 coordinate system as the reference template. The position of the following unit following the movement of the patient at least partially coincides with the position of the patient means that the position information of the following unit at the second time node is within the coverage range of the position information of the patient at the first time node or is completely consistent with the position information of the patient at the first time node. The first movement path refers to the movement path generated by referring to the movement path of the patient to guide the movement of the following unit.
[0013] The remote control unit generates a first movement path based on at least two position information of the patient sent by the second part. The selection rule for generating the position information for generating the first movement path is that the time of generating the position information is adjacent. Based on the position information of the patient generated at the first time node, the remote control unit judges the correctness of the position of the following unit at the second time node. Preferably, based on the coverage range of the position information of the patient generated at the first time node, when the position information of the following unit at the second time node enters its coverage range, the remote control unit completes an information confirmation.
[0014] Based on the preset number of position information used to generate the first movement path related to the patient, the remote control unit can update the position information farthest in time from the new position information generated by the second part, such as Figure 3The first moving path is always displayed with the position information most relevant to the current displacement of the patient, thereby ensuring that the first moving path always exhibits the path most relevant to the current displacement of the patient. Preferably, the preset number of position information is three. Based on the memory of the remote control unit, the preset number of position information can be manually selected. In theory, the larger the memory of the remote control unit, the more preset numbers of position information can be selected. For example, when the number of position information used to generate the first moving path related to the patient is set to three, when the second part generates a fourth position information, the remote control unit can record the fourth position information as the third position information, delete the first position information most distant in time from the fourth position information, and update the second position information second most distant in time from the fourth position information to the first position information, so that the first moving path remains three position information while changing the moving information.
[0015] When the position information of the second part changes, the first part starts the positioning function. The latest updated position information of the first part is adjacent to the latest updated position information of the second part. The remote control unit generates two position information based on the moving path generated by the two position information of the second part. The two position information is the preset two position information that provides navigation information for the accompanying unit. Preferably, the two position information coincides with the two position information on the first moving path.
[0016] For example, when the patient moves, the starting position is the first position information, and the movement to the preset distance is the second position information. The remote control unit can generate the corresponding second position information for the moving path of the first part based on the first position information, i.e., the remote control unit can change the first position information generated by the second part to the second position information of the moving path of the first part, and control the accompanying unit to move from its initial position to the position corresponding to the second position information.
[0017] According to a preferred embodiment, the preset distance can be the distance of one step of an adult. Particularly preferably, the preset distance can be between 0.25-0.7m.
[0018] According to a preferred embodiment, the update node of the position information of the accompanying unit and the patient is to update a new position information every time period α. Preferably, the position information of the accompanying unit and the position information of the patient differ by a time period α. For example, the position information of the patient at the first time node is (x, y), and the position information at the second time node is (x', y'). The position information of the accompanying unit at the second time node can be (x', y'). Preferably, if the position information of the accompanying unit at the second time node is within the range covered by the position information of the patient at the first time node, the remote control unit updates the position information of the accompanying unit and the patient.
[0019] According to a preferred embodiment, the accompanying unit can be an oxygen supply robot.
[0020] The beneficial effects of the present technical solution are:
[0021] (1) The present application provides an oxygen supply robot that can accompany a patient. When the patient produces a significant displacement (for example, the length of the significant displacement can refer to more than half the length of the oxygen tube between the patient and the oxygen supply robot, so that the oxygen tube can be stably hung between the patient's nose without falling off through the accompanying behavior of the oxygen supply robot), the oxygen supply robot can always accompany the patient and ensure that the distance between the oxygen supply robot and the patient is less than the length of the oxygen supply tube connecting the two, and can maintain complete oxygen therapy when the patient moves based on his own needs.
[0022] (2) Based on the patient's movement path, the remote control unit can move in a way that covers the patient's movement path. Unlike the accompanying robots in the prior art, the accompanying unit in the present application is connected to the patient through the oxygen inhalation tube, and therefore the oxygen inhalation tube will become an important factor affecting the joint travel of the two during the travel (for example, when there are obstacles in the path, the oxygen inhalation tube is wound around the obstacles, causing the accompanying unit to be unable to travel normally). Since there are no obstacles in the patient's movement path that affect travel, the accompanying unit travels in a way that covers the patient's movement path, thereby avoiding the oxygen inhalation tube between the patient and the accompanying unit being hindered by obstacles on the movement path during movement.
[0023] According to a preferred embodiment, after receiving the patient's position information sent by the second part, the remote control unit can generate an instruction to control the movement of the accompanying unit, wherein the target position of the movement of the accompanying unit is the position information of the patient sent by the second part or a position within the coverage range of the position information of the patient sent by the second part. The accompanying unit reaches the position specified by the remote control unit after receiving the position information sent by the remote control unit. When the accompanying unit moves to the corresponding position based on the position information sent by the remote control unit, the accompanying unit can send its current position information to the remote control unit. When the position information of the accompanying unit at the second time node is within the coverage range of the position information of the patient at the first time node or completely consistent with the position information of the patient at the first time node, the remote control unit completes one information confirmation.
[0024] The second part can also collect images of the environment in which the patient is located. When the remote control unit completes the first information confirmation, the first part of the accompanying unit collects images of the current environment when the accompanying unit reaches the designated location. When the image collected by the second part at the first time node matches or partially matches the image collected by the accompanying unit at the second time node, the remote control unit completes the second information confirmation.
[0025] After the two information confirmations, the remote control unit can attribute the position information and image information data collected by the second part at the first time node to the historical database, and update the position information of the second part at the second time node to the position information of the accompanying unit at the third time node. Timely updating the position information can keep the displacement between the patient and the accompanying unit within the preset distance range.
[0026] Preferably, the image collection range of the accompanying unit has an intersection between two adjacent locations, so that the images transmitted by the first part and the images transmitted by the second part have at least partially similar features when the second confirmation is performed.
[0027] The beneficial effects of the technical solution are as follows:
[0028] Since the displacement of the patient is not large, relying only on the positioning device to update the position information of the patient will result in a large positioning error. When the position information of the patient and the accompanying unit at each time node is partially deviated, the movement path of the patient and the accompanying unit will be worse and worse, and the oxygen tube attached to the patient will also fall off from the patient as the distance between the accompanying unit and the patient becomes farther and farther, causing the interruption of the oxygen inhalation process of the patient.
[0029] The present application generates a determination result of whether the movement path of the accompanying unit is consistent with the movement path of the patient through the first information confirmation and the second information confirmation, to avoid the above problems.
[0030] Compared with the position information used in the first confirmation, the image information used in the second confirmation will not change since most of the objects in the environment will not change, i.e., the image of the location environment collected by the second part at the first time node is consistent with the image of the location environment collected by the accompanying unit at the second time node. By using the environmental image as the basis for determining whether the patient and the accompanying unit are in the same location, the deviation of the electronic device itself in information collection can be avoided, thereby increasing the accuracy of determining the position information of the patient and the accompanying unit.
[0031] According to a preferred embodiment, when the first information confirmation is not in compliance, and the result indicates that the accompanying unit has not reached the designated location, the remote control unit re-sends the location information of the patient at the first time node to correct the displacement direction of the accompanying unit.
[0032] According to a preferred embodiment, when the second information confirmation is not in compliance, the remote control unit can preferentially trigger the alarm module to generate a second part capable of representing the patient's location confirmation procedure. Preferably, the confirmation procedure can be a voice prompting the current patient to confirm whether the second part is on his body. The patient can operate the second part to inform the remote control unit that the second part can represent the patient's location.
[0033] Based on this, the remote control unit will reposition the location of the second part, and generate the location information of the accompanying unit at the second time node based on the new location information at the first time node. The accompanying unit can adjust its relative position with the patient based on the location information at the second time node sent by the remote control unit, and re-perform the first and second confirmations.
[0034] The beneficial effects of the technical solution are:
[0035] When the second confirmation fails, there are several possibilities:
[0036] (1) The second part falls off the patient, at which time the location information and image information sent by the second part to the remote control unit cannot represent the patient's location information and the image information of the environment in which the patient is located.
[0037] (2) When the distance between the first part and the second part is relatively close, the first part and the second part with positioning function may generate larger error in the position information of the first part and / or the second part during the first confirmation due to slow signal or positioning information refresh speed, causing the accompanying unit to enter the wrong position and collect the wrong image.
[0038] Therefore, when the determination result of the second confirmation does not pass, in order to correct the erroneous movement behavior of the accompanying unit and make the accompanying unit move on the correct path, the system will in turn exclude the causes of this problem.
[0039] By forcibly refreshing the position information of the first part and the second part, the data authenticity of the position information between the first part and the second part is increased. After forced refreshing, the remote control unit can reconfirm the relative position of the first part and the second part, and adjust the moving position of the accompanying unit, so that the accompanying unit can timely change its distance from the patient. When the accompanying unit has an erroneous displacement, the remote control unit can timely adjust the position information of the accompanying unit so that the accompanying unit will not generate displacement based on two consecutive erroneous position information.
[0040] According to a preferred embodiment, when the second part does not move for a time period β, the remote control unit can control the following unit to position the second part and collect the action of the patient in the third person perspective. The time period β can be the mean value of the time required for the daily behavior of the patient, such as the mean value of the time for the patient to drink water and the time for the patient to go to the toilet. Preferably, β is 10-60s. Particularly preferably, β is 30s.
[0041] Based on the image of the patient, the remote control unit can generate the state information of the patient. The state information of the patient includes the micro-motion state, the vigorous motion state and the critical state.
[0042] When the patient is in the micro-motion state, the following unit does not change the current oxygen supply condition provided for the patient;
[0043] When the patient is in the vigorous motion state, the following unit changes the current oxygen supply condition provided for the patient to the pre-set oxygen supply condition required for the patient in the vigorous motion state;
[0044] When the patient is in the critical state, the following unit does not change the current oxygen supply condition provided for the patient, and sends an alarm to the guardian of the patient.
[0045] The beneficial effects of the technical solution are:
[0046] In the prior art, in addition to the fact that the emergency patient will remain relatively calm during oxygen inhalation and will not affect the oxygen inhalation process, the general oxygen inhalation patient, such as the patient who is hypoxic due to pneumonia, may move during oxygen inhalation. At the same time, with the different motion states of the patient entering different positions, the amount of oxygen consumed by the patient's body will also change.
[0047] When the patient enters a more vigorous motion state or is in an action that affects oxygen supply (for example, squatting), the following unit can provide the patient with oxygen supply of different proportions in real time by detecting the physiological state of the patient.
[0048] The technical solution can supplement the oxygen consumed by the patient in time when the patient enters a motion state with a large amount of oxygen consumption, such as squatting in the toilet, so as to increase the curative effect of oxygen inhalation of the patient.
[0049] When the patient moves by walking to fulfill his physiological needs, the walking speed is the most important factor affecting the patient's physical state during the movement, especially when the patient moves on flat ground. The present application can determine the patient's gait by collecting the patient's characteristics during the movement, and determine whether the patient's moving speed affects his physical state by combining the patient's gait and blood oxygen saturation. The detection of only one factor will cause errors in the detection of the patient's physical state. For example, even if the patient's walking speed does not affect the patient's physiological state, the patient's blood oxygen saturation will decrease due to changes in the patient's mood or other factors. The present application can determine the patient's physiological state by combining the patient's blood oxygen saturation and gait, thereby avoiding inducing asthma in the patient due to fast moving speed.
[0050] According to a preferred embodiment, the remote control unit can obtain the patient's gait based on the patient image collected by the image collection component provided on the accompanying unit, compare the patient's gait parameters with standard gait parameters. The remote control unit can at least divide the patient's current physiological state into standard gait and ataxia gait. When the patient is in standard gait, the accompanying unit can move according to the position information transmitted by the remote control unit. Preferably, the system includes a limit unit that limits the patient's moving speed. The limit unit can be a limit rope connected to the accompanying unit and the patient respectively. The limit rope is provided as an elastic rope. The limit unit also includes a component with voice or image prompting function. When the patient's current walking speed is higher than the safe walking speed generated by the remote control unit, the limit unit can slow down the moving speed by pulling the patient's wrist or prompting the patient by voice. Preferably, the patient's gait analysis method can be the same as the analysis method of Chinese patent No. CN101609507B.
[0051] When the patient is in ataxia gait, the remote control unit can further determine whether to limit the patient's moving speed in combination with other detected factors of the patient.
[0052] According to a preferred embodiment, when the patient is in ataxia gait, the remote control unit controls the blood oxygen saturation detection component to start working based on the patient's posture change.
[0053] When the blood oxygen saturation of the patient is lower than the first threshold, the remote control unit reduces the moving speed of the patient by the prompting of the moving restriction unit to reduce the oxygen consumption of the patient and avoid the hypoxia symptoms caused by the intense movement (too fast moving speed). When the moving speed of the patient is restricted by the moving restriction unit, the frequency of sending the position information by the first part and the second part increases due to the relatively large change of the moving speed of the patient. Specifically, the frequency increase means that the time interval length is shortened, i.e. the time interval between the first time node and the second time node is shortened. The shortened time interval is also based on the manual setting, i.e. before the system is used, the patient or the medical staff can preset a plurality of time intervals.
[0054] When the blood oxygen saturation of the patient is higher than the first threshold, the remote control unit can normally provide the displacement information for the accompanying unit.
[0055] Preferably, the blood oxygen saturation is preset based on the state of the patient, i.e. when the patient only supplements oxygen to relieve snoring at night, the first threshold of the blood oxygen saturation of the patient is 98%. But when the patient is an early patient of pulmonary obstruction syndrome, the first threshold of the blood oxygen saturation of the patient is 96%.
[0056] For example, after the patient sits on the toilet for a long time, when the patient changes from the squatting position to the standing position and moves from the toilet to the bedroom, the remote control unit detects that the patient is in the ataxia state. When the patient is in the ataxia state and changes from the squatting position to the standing position, the remote control unit starts the blood oxygen saturation detection assembly. When the blood oxygen saturation detection assembly detects that the blood oxygen saturation of the patient is lower than 96%, the moving restriction rope can pull the wrist of the patient with a preset force to prompt the patient to reduce the walking speed. Preferably, the preset force is lower than 20N to prevent the excessive force from affecting the patient's walking.
[0057] The gait information can be used to feedback the physiological state of the patient and judge whether the moving speed of the patient is in the safe range based on the current physiological state of the patient. BRIEF DESCRIPTION OF DRAWINGS

[0063] The application will be described in detail below with reference to the accompanying drawings.
[0064] In this application, the "proximal end" refers to the end close to the operator, and the "distal end" refers to the end away from the operator.
[0065] Embodiment 1
[0066] This embodiment provides an adaptive oxygen inhalation device capable of changing oxygen supply conditions based on different states of a patient. The adaptive oxygen inhalation device is suitable for a home environment. The adaptive oxygen inhalation device is suitable for a hospital environment.
[0067] This embodiment takes the patient's room as an example. At the initial use, the following unit 100 can scan the environment that the patient may pass through, including the patient's room, bathroom, kitchen, and living room, and the remote control unit 200 generates a region map that the patient may go to based on the position information and image information transmitted by the following unit 100.
[0068] When the patient gets up at midnight to go to the bathroom, if the position of the second part 112 worn on the patient changes, the remote control unit 200 will determine the position of the following unit 100 based on the report of the positioning information of the first part 111. The remote control unit 200 can determine the position of the patient based on the report of the positioning information of the second part 112. Preferably, the position information refers to the position information of the first part 111 or the second part 112 in the preset map.
[0069] Based on the preset number of position information used to generate the first movement path related to the patient, the remote control unit 200 can update the position information farthest in time from the new position information generated by the second part 112. For example, the number of position information used to generate the first movement path related to the patient is set to three, when the second part 112 generates a fourth position information, the remote control unit 200 can record the fourth position information as the third position information, and delete the first position information farthest in time from the fourth position information, and update the second position information second farthest in time from the fourth position information as the first position information, so that the first movement path maintains three position information while changing the movement information.
[0070] When the second part 112 is displaced, the first part 111 opens the positioning function. The first part 111 is adjacent to the position information of the second part 112. The remote control unit 200 generates two position information based on the two position information of the second part 112. The two position information is the preset two position information for providing navigation information for the accompanying unit 100. Preferably, the two position information coincides with the two position information on the first movement path.
[0071] For example, when the patient moves, the initial position is the first position information, and the movement to the preset distance is the second position information. The remote control unit 200 can generate the corresponding second position information for the movement path of the first part 111 based on the first position information, that is, the remote control unit 200 can change the first position information generated by the second part 112 to the second position information of the movement path of the first part 111, and control the accompanying unit 100 to move from the initial position to the position corresponding to the second position information.
[0072] According to a preferred embodiment, based on the function setting of different regions in the preset map, when the patient is in different regions, the remote control unit 200 can determine whether the patient is in a normal state in combination with the action of the patient. Specifically, when the patient changes from standing to lying down, the system determines that the patient is in a critical state. Further, the system determines whether the patient is normal in combination with the region where the patient is currently located. For example, when the patient enters the region of the bathroom, in combination with the patient being in a critical state, the system can determine that the patient has an accident and send a warning message to the guardian of the patient. For example, the system dials the phone of the guardian.
[0073] For example, when the patient enters the bathroom, the accompanying unit 100 collects that the posture of the patient changes to squat. The remote control unit 200 determines that the patient is in a state of strenuous exercise and controls the oxygen supply unit module 120 of the accompanying unit 100 to change the oxygen supply condition.
[0074] According to a preferred embodiment, the oxygen supply condition is different for patients in different states. The oxygen content and / or flow rate provided for patients in a state of mild exercise is lower than the oxygen content and / or flow rate provided for patients in a state of strenuous exercise. The specific values of oxygen content and flow rate are confirmed in accordance with the doctor's advice. For example, for patients with chronic pulmonary embolism, when they are in a state of mild exercise, the oxygen concentration is 35%, and the gas flow rate is 2L / min. When the patient is in a state of strenuous exercise, the oxygen concentration is 38%, and the gas flow rate is 2.5L / min.
[0075] Since the change of the patient's posture is caused based on some special state or environment, the method of combining the patient's environment and action double information to determine whether the current posture of the patient is normal can reduce the operation frequency of misjudgment. For example, when the patient is located in the area of the bathroom, the posture of lying down is impossible to appear when the patient is in the normal state. However, when the patient is located in the area of the living room, the patient can lie down on the sofa, and thus the patient in the lying down posture at this time is in the normal state.
[0076] The remote control unit 200 confirms the environment passed by the patient based on the image collected by the detection module 110, and the remote control unit 200 confirms the state of the patient based on the relationship between the environment and the patient.
[0077] Further, the second part 112 can also contain a blood oxygen monitoring component. Based on the patient blood oxygen information transmitted by the second part 112 and the patient action information transmitted by the first part 111, the remote control unit 200 can generate a request for symptom description in combination with the change of action and the change of blood oxygen, for example, the alarm module 130 outputs the signs inquiry such as "whether chest tightness", "whether black in front of eyes", "whether sudden sweating" to the patient in the form of voice prompt, and the corresponding judgment of the current physical state of the patient is generated (for the patient with mixed chronic diseases of the lung and other underlying diseases, to judge whether the disease will occur or symptoms such as fainting, shock, etc. when the patient enters the bathroom or other non-ward area alone).
[0078] According to a preferred embodiment, when the environment is a hospital, the determination of the state of vigorous exercise can include the change of the posture of the patient and the slope of the ground in the environment. The preset oxygen supply condition is generated based on the possible vigorous exercise in the fixed path, wherein the preset oxygen supply condition is preset in the system in advance by manual.
[0079] For example, when the accompanying unit 100 collects the image that the patient needs to go up and down the stairs or needs to pass through the ground with slope, the remote control unit 200 determines that the patient is in the state of vigorous exercise.
[0080] In the case of diagnosing chronic diseases related to respiration and needing to go to the hospital for treatment or home oxygen therapy periodically, the system provided in the embodiment which can accompany the patient and provide oxygen for the patient solves the problem that the old people (especially the single and lonely old people) cannot continuously complete the oxygen therapy when they need to go to the bathroom to solve the personal physiological problems or go to get water during the oxygen therapy.
[0081] According to a preferred embodiment, the accompanying unit 100 and the remote control unit 200 are respectively contained in separate physical modules or housings.
[0082] Embodiment 2
[0083] The oxygen supply unit module 120 includes a gas delivery assembly. The gas delivery assembly is coupled to an oxygen inlet, an air inlet, a gas mixture outlet for mixing oxygen and air to form a gas mixture having a delivered oxygen concentration and for delivering the gas mixture to a patient. The air inlet receives a mixture of breathable gas.
[0084] The gas delivery assembly includes all of the mechanical valves, sensors, microcontrollers, analog electronics, power supplies, etc. to receive, process, and deliver the gas mixture to the patient. The gas delivery assembly specifically includes a control subsystem interface, one or more optional microcontrollers, an oxygen inlet, an air inlet, a gas mixture outlet, an optional exhalation inlet, and a gas delivery mechanism. The gas delivery assembly mixes oxygen and air to form a gas mixture having a delivered oxygen concentration and then delivers the gas mixture to a patient through the gas mixture outlet. The gas delivery assembly receives oxygen through the oxygen inlet and receives high pressure air through the air inlet, filters and mixes the gases through a gas mixer, and then delivers the appropriate pressure or volume of gas mixture through the gas mixture outlet. Based on the pre-set oxygen delivery conditions, the gas delivery assembly receives oxygen through the oxygen inlet and receives high pressure air through the air inlet, filters the gases, and then delivers the calculated flow rate of air and the calculated flow rate of oxygen to the patient outlet through the gas mixture outlet.
[0085] The system also includes a blood oxygen saturation detection assembly. Preferably, the second portion 112 and the blood oxygen saturation detection assembly are disposed in the same physical module, e.g., the physical module is secured to a patient's finger or arm location.
[0086] The patient's blood oxygen saturation changes when the patient's posture changes. Preferably, the remote control unit 200 determines that the patient is in an intense motion state when the following image is captured by the accompanying unit 100: the patient needs to go up or down the stairs or needs to pass a surface having a slope.
[0087] Based on the determination that the patient is in an intense motion state, the remote control unit 200 controls the blood oxygen saturation detection assembly to turn on and adjusts the oxygen concentration and gas flow rate provided to the patient based on the patient's real-time blood oxygen saturation. Preferably, when the accompanying unit 100 is in a hospital environment, the accompanying unit 100 is able to transmit the detected blood oxygen saturation data to a doctor's workstation or a nursing workstation in real time. When the accompanying unit 100 is in a home environment, the accompanying unit 100 is able to record the patient's real-time blood oxygen saturation data and send the relevant data to a medical staff's handheld terminal when the medical staff needs it.
[0088] The system is also provided with a charging component. For patients who periodically visit the hospital, the process of queuing and paying each time is very cumbersome. The charging component of the system can identify the identity of the patient and record the oxygen intake of the patient each time. Specifically, the oxygen intake of the patient refers to: after the patient confirms the identity information on the accompanying unit 100 through the identity recognition component such as an identity recognition card, the accompanying unit 100 starts oxygen supply and begins charging. After the patient operates the accompanying unit 100 again to turn off the oxygen supply, the charging component stops charging. The charging component can record the oxygen intake of the patient corresponding to the identity, so that the patient can realize single clearing of the fee after multiple oxygen intakes.
