Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to an oxygen generator and an oxygen generator and breathing integrated machine comprising the oxygen generator. Background Art

[0002] An oxygen concentrator is a medical device designed to provide convenient and mobile oxygen therapy to patients who require an additional oxygen supply. This equipment is commonly used to treat conditions such as chronic obstructive pulmonary disease (COPD), heart disease, pulmonary fibrosis, asthma, and for travel to high altitudes or low oxygen environments. Portable oxygen concentrators work by extracting oxygen from the surrounding air and then providing it to the patient to help them maintain normal oxygen levels.

[0003] Oxygen concentrators are usually used in conjunction with blood oxygen saturation detectors. The oxygen concentrator supplies oxygen to the user. At the same time, the blood oxygen saturation detector monitors the user's blood oxygen concentration and displays it, which is convenient for medical staff or the user's family to monitor in time. However, when the blood oxygen saturation detector detects that the blood oxygen saturation reaches 100%, the existing oxygen concentrator is still in working state, which brings a certain degree of waste; moreover, the molecular sieve in the oxygen concentrator is a consumable material, which causes serious wear and tear after long-term operation, and the cost of use is high. Utility Model Content

[0004] In view of the above-mentioned defects of the prior art, the utility model provides an oxygen generator, wherein an oxygen channel and an air channel are provided in the oxygen generator, and the oxygen channel and the air channel can be switched according to the needs of use. To this end, the utility model also provides an oxygen-generating and breathing integrated machine including the oxygen generator, and the oxygen generator is used in conjunction with a blood oxygen saturation detector. When the blood oxygen saturation detector detects that the blood oxygen saturation of the user reaches 100%, the oxygen generator switches from the oxygen channel to the air channel to supply air to the user, thereby reducing the loss of the molecular sieve and reducing the production cost.

[0005] In a first aspect of the utility model, an oxygen production device is provided, comprising a body and a compressor, wherein an oxygen channel and an air channel are arranged in the body, and an air outlet of the compressor is connected to the oxygen channel and the air channel arranged in parallel;

[0006] The air inlet ends of the oxygen channel and the air channel are provided with valve bodies for controlling the opening of the oxygen channel / air channel, and the air outlet ends of the oxygen channel and the air channel are connected to the human body through pipelines;

[0007] A molecular sieve component and an oxygen storage tank are arranged in the oxygen channel, and the gas outlet end of the molecular sieve component is connected to the oxygen storage tank; the oxygen storage tank is used to supply oxygen to the human body.

[0008] The valve body is used to control the opening of the oxygen channel, and the compressed air discharged from the compressor enters the molecular sieve assembly. The produced oxygen enters the oxygen storage tank and is supplied to the human body at a certain flow rate. When there is no need to supply oxygen, the valve body is used to control the opening of the air channel, and the air discharged from the compressor enters the air channel, and the molecular sieve is converted to a non-working state, thereby reducing the loss of the molecular sieve.

[0009] As a preferred embodiment, an air intake flow regulating valve is provided at the air intake of the compressor.

[0010] The setting of the intake flow control valve is used to adjust the amount of gas entering the compressor.

[0011] As a preferred embodiment, outlet ends of the oxygen channel and the air channel are provided with outlet flow regulating valves.

[0012] The setting of the gas outlet flow regulating valve is used to adjust the gas discharge volume of the oxygen channel or the air channel.

[0013] As a preferred embodiment, the molecular sieve assembly includes a plurality of molecular sieve adsorption tubes.

[0014] As a more preferred embodiment, the molecular sieve assembly includes two molecular sieve adsorption tubes.

[0015] As a preferred embodiment, the compressor is an air compressor.

[0016] As a preferred embodiment, the valve body is a solenoid valve.

[0017] The second aspect of the utility model provides an oxygen-generating and breathing integrated machine, comprising the above-mentioned oxygen-generating device, wherein the oxygen-generating and breathing integrated machine further comprises a blood oxygen saturation detector.

[0018] As a preferred embodiment, the oxygen-generating and breathing integrated machine is also provided with a controller, a WIFI transmission module and a speaker. The controller is electrically connected to the valve body, the WIFI transmission module and the speaker, and the blood oxygen saturation detector is electrically connected to the controller.

[0019] As a preferred embodiment, the oxygen-generating and breathing integrated machine further includes an oxygen concentration sensor, and the oxygen concentration sensor is connected to the controller via a WIFI transmission module.

[0020] Compared with the prior art, the utility model has the following beneficial effects:

[0021] (1) The oxygen production device of the utility model is provided with an oxygen channel and an air channel, and is switched between the oxygen channel and the air channel by a valve body, so as to meet different usage requirements.

[0022] (2) The oxygen-generating and breathing machine of the present invention uses the oxygen-generating device in conjunction with a blood oxygen saturation detector. When the blood oxygen saturation detector detects that the user's blood oxygen saturation is close to 100%, the oxygen channel is replaced by the air channel, and the molecular sieve is converted to a non-working state, thereby reducing the loss of the molecular sieve and reducing the production cost; when the blood oxygen saturation detector detects that the user's blood oxygen saturation is lower than 96%, the air channel is switched to the oxygen channel, and the molecular sieve is restored to a working state; the oxygen-generating and breathing machine of the present invention realizes dynamic oxygen production by changing the gas passage by monitoring the user's blood oxygen saturation.

[0023] (3) The oxygen-generating breathing machine of the utility model is provided with an ambient oxygen sensor. When the ambient oxygen concentration is detected to be lower than 18%, the air intake and air outlet volumes can be adjusted by controlling the air intake flow regulating valve and the air outlet flow regulating valve to avoid the impact of low ambient oxygen concentration on surrounding personnel.

[0024] The concept, specific structure and technical effects of the present invention will be further described below in conjunction with the accompanying drawings to fully understand the purpose, characteristics and effects of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0031] In order to make the technical means, creative features, objectives and effects of the utility model easier to understand, the utility model is further described below with reference to specific diagrams. However, the utility model is not limited to the following implementation cases.

[0032] It should be noted that the structures, proportions, sizes, etc. illustrated in the drawings in this specification are only used to match the contents disclosed in the specification so that people familiar with this technology can understand and read them. They are not used to limit the conditions under which the present utility model can be implemented, so they have no substantive technical significance. Any structural modification, change in proportional relationship or adjustment of size should still fall within the scope of the technical contents disclosed in the present utility model without affecting the effects and purposes that can be achieved by the present utility model.

[0033] Oxygen is a necessity for people's lives. Oxygen concentrators are widely used in the treatment of chronic obstructive pulmonary disease (COPD), heart disease, pulmonary fibrosis, asthma and other diseases, as well as travel in high altitude areas or low oxygen environments. Oxygen concentrators achieve the effect of oxygen production through the principle of molecular sieve pressure swing adsorption. The oxygen concentrator is equipped with an air compressor and a closed container with a molecular sieve, usually a molecular sieve adsorption tube. When working, air is injected into the molecular sieve adsorption tube through the air compressor, and the pressure in the molecular sieve adsorption tube increases accordingly. The molecular sieve therein absorbs a large amount of nitrogen in the air as the ambient pressure increases, while the oxygen in the air still exists in the form of gas and is collected through certain pipelines, such as entering an oxygen storage tank. This process is usually called the "adsorption" process; when the molecular sieve in the molecular sieve adsorption tube absorbs nitrogen to a certain extent, the container is exhausted and decompressed. As the ambient pressure decreases, the molecular sieve's ability to adsorb nitrogen decreases, and the nitrogen is released from the inside of the molecular sieve and discharged as waste. This process is usually called the "desorption" process.

[0034] In common oxygen production equipment, in order to ensure continuous and stable oxygen production, two or more molecular sieve adsorption tubes are used, so that one container is in the "adsorption" process while the other container is in the "desorption" process, and vice versa. In this way, oxygen is produced from the air and delivered to the patient for inhalation, thereby improving the patient's blood oxygen saturation.

[0035] However, in the existing oxygen production equipment, the molecular sieve is basically in working state all the time, that is, when the blood oxygen saturation detector 12 detects that the patient's blood oxygen saturation is close to 100%, the oxygen production equipment still continues to supply oxygen to the patient, which causes a great waste. Moreover, the molecular sieve is a consumable material, and being in working state for a long time leads to serious loss, which increases the cost of use.

[0036] In order to solve the above problems, the present application sets an oxygen channel 10 and an air channel 11 in the oxygen production equipment, and sets a molecular sieve and an oxygen storage tank 1 in the oxygen channel 10. The molecular sieve adsorbs the air delivered by the compressor 5, and the obtained oxygen is injected into the oxygen storage tank 1 and supplied to the patient through a certain flow rate. When the blood oxygen saturation detector 12 detects that the patient's blood oxygen saturation is close to 100%, at this time, the oxygen channel 10 is switched to the air channel 11 through control, and the compressor 5 delivers air to the air channel 11 for the patient to inhale. At this time, the molecular sieve is in a non-working state to reduce losses.

[0037] Example 1

[0038] like Figure 2 , an oxygen production device (one side of the shell is removed), including a body 13 and a compressor 5. The compressor 5 can be arranged inside the body 13 or outside the body 13. Different arrangements of the compressor 5 can be selected according to the size of the internal space of the oxygen production device and the needs of use. When arranged outside the body 13, it can be installed on the outer wall of the body 13 or on the ground or platform near the oxygen production device. In this embodiment, the compressor 5 is selected to be arranged inside the body 13. The compressor 5 here is an air compressor. The compressor 5 is provided with an air inlet and an air outlet. The air inlet of the compressor 5 is connected to the atmospheric environment. In order to adjust the air flow entering the compressor 5, an air inlet flow regulating valve 2 is provided at the air inlet of the compressor 5.

[0039] like Figure 1 , 4 An oxygen channel 10 and an air channel 11 are arranged in the body 13, and the air outlet of the compressor 5 is connected to the oxygen channel 10 and the air channel 11 arranged in parallel; the parallel arrangement here is not limited to the side-by-side arrangement, but also includes the non-side-by-side arrangement, which only means that the air discharged by the compressor 5 can enter two branches, one branch is the oxygen channel 10, and the other branch is the air channel 11. Any arrangement that meets this effect belongs to the category of parallel arrangement in this application.

[0040] The air inlet ends of the oxygen channel 10 and the air channel 11 are provided with a valve body 9 for controlling the opening of the oxygen channel 10 / air channel 11. The valve body 9 here is a solenoid valve. The valve body 9 can control the oxygen channel 10 to be opened and the air channel 11 to be closed, or the air channel 11 to be opened and the oxygen channel 10 to be closed, so that the oxygen channel 10 and the air channel 11 can be switched with each other. The air outlet ends of the oxygen channel 10 and the air channel 11 are connected to the human body through a pipeline. When the oxygen channel 10 is opened and the air channel 11 is closed, the patient inhales oxygen; when the oxygen channel 10 is closed and the air channel 11 is opened, the patient inhales air.

[0041] like Figure 3(Remove the outer shell), a molecular sieve component 4 and an oxygen storage tank 1 are arranged in the oxygen channel 10. When the air discharged from the compressor 5 enters the oxygen channel 10, the molecular sieve component 4 adsorbs nitrogen and oxygen is discharged therefrom. The air outlet of the molecular sieve component 4 is connected to the oxygen storage tank 1. The oxygen storage tank 1 stores the produced oxygen and supplies it to the patient at a certain flow rate. The molecular sieve component 4 includes a plurality of molecular sieve adsorption tubes. Preferably, the molecular sieve component 4 includes two molecular sieve adsorption tubes, so when one of the molecular sieve adsorption tubes undergoes an "adsorption" process to discharge the produced oxygen, the other molecular sieve adsorption tube undergoes a "desorption" process and serves as a spare molecular sieve adsorption tube.

[0042] In order to adjust the amount of gas discharged from the oxygen channel 10 or the air channel 11 , a gas outlet flow regulating valve 3 is provided at the gas outlet end of the oxygen channel 10 and the air channel 11 .

[0043] The body 13 is also provided with a WIFI transmission module 7, a controller 6 and a speaker 8. The WIFI transmission module 7 is a chip basic circuit set with an integrated WIFI transmission function, and is used for wireless network communication. The controller 6 is electrically connected to the valve body 9, the air inlet flow regulating valve 2, and the air outlet flow regulating valve 3 of the oxygen generator.

[0044] Example 2

[0045] like Figure 4 , an oxygen-generating and breathing integrated machine, comprising the oxygen-generating device in Example 1 and a blood oxygen saturation detector 12. The blood oxygen saturation detector 12 uses optical principles to measure the oxygen content in the blood by detecting a luminous indicator. The present application can select a commercially available blood oxygen saturation detector 12. The blood oxygen saturation detector 12 is usually installed near a bed to detect the patient's blood oxygen saturation. The blood oxygen saturation detector 12 is connected to the controller 6 through a cable to send an electrical signal to the controller 6.

[0046] When the blood oxygen saturation detector 12 detects that the patient's blood oxygen saturation reaches 100%, the blood oxygen saturation detector 12 transmits the signal to the controller 6, and the controller 6 controls the valve body 9 to switch the channel from the oxygen channel 10 to the air channel 11, and the air output by the compressor 5 enters the air channel 11, and the molecular sieve is converted to a non-working state. At this time, the patient inhales air, which reduces the loss of the molecular sieve. On the contrary, when the blood oxygen saturation detector 12 detects that the patient's blood oxygen saturation is low, such as less than 96%, the blood oxygen saturation detector 12 transmits the signal to the controller 6, and the controller 6 controls the valve body 9 to switch the channel from the air channel 11 to the oxygen channel 10, and the air output by the compressor 5 enters the oxygen channel 10, and the molecular sieve resumes its working state.

[0047] Because the compressor 5 absorbs the surrounding air, after long-term use, the ambient oxygen concentration in the space may be low. When the ambient oxygen concentration is lower than 18%, the human body will experience fatigue, memory loss, arrhythmia and other adverse symptoms, which will have adverse effects on other people around. In order to solve this problem, an oxygen concentration sensor 14 is installed in the environment, and a speaker 8 is installed on the body 13. Here, the oxygen concentration sensor 14 is a commercially available product, which can be selected from the Weimengshi VMS-3002-02 sensor. The oxygen concentration sensor 14 is connected to the controller 6 via the WIFI transmission module 7, and the oxygen concentration sensor 14 can transmit signals to the controller 6.

[0048] During specific use, when the oxygen concentration sensor 14 detects that the ambient oxygen concentration is lower than 18%, and the patient's blood oxygen saturation is greater than 96%, the controller 6 controls the air intake flow regulating valve 2 to reduce the air intake volume. At the same time, the speaker 8 issues a voice prompt for ventilation.

[0049] When the oxygen concentration sensor 14 detects that the ambient oxygen concentration is greater than 18%, and the patient's blood oxygen saturation is greater than 98%, the controller 6 controls the valve body 9 to switch to the air channel 11, and the molecular sieve is converted to a non-working state, thereby extending the service life of the molecular sieve.

[0050] When the oxygen concentration sensor 14 detects that the ambient oxygen concentration is lower than 18%, and the patient's blood oxygen saturation is lower than 96% at this time, the controller 6 controls the air intake flow regulating valve 2 to increase the air intake volume, and the air outlet flow regulating valve 3 to increase the air outlet volume to ensure that the patient's blood oxygen saturation is not lower than 90%. At the same time, the controller 6 controls the speaker 8 to broadcast the window opening for ventilation, reminding the surrounding people to temporarily stay away from this environment.

[0051] When the oxygen concentration sensor 14 detects that the ambient oxygen concentration is greater than 18%, and the patient's blood oxygen saturation is lower than 96%, the controller 6 controls the air inlet flow regulating valve 2 and the air outlet flow regulating valve 3 to be at the maximum value.

[0052] The oxygen-generating and breathing integrated machine of the utility model can be dynamically adjusted according to the ambient oxygen concentration and the patient's blood oxygen saturation to achieve dynamic oxygen production.

[0053] The preferred specific embodiments of the utility model are described in detail above. It should be understood that ordinary technology in the field can make many modifications and changes according to the concept of the utility model without creative work. Therefore, any technical solution that can be obtained by a technician in the technical field based on the concept of the utility model through logical analysis, reasoning or limited experiments on the basis of the existing technology should be within the scope of protection determined by the claims.
