Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to an oxygen delivery system and oxygen supply equipment with intelligent flow control function. Background Art

[0002] Oxygen inhalation is the inhalation of oxygen, which is a commonly used clinical treatment method. Oxygen inhalation is used to correct hypoxia, increase the level of arterial oxygen partial pressure and oxygen saturation, and promote metabolism. It is one of the important methods for auxiliary treatment of various diseases. The pace of life of modern people is accelerated, and mental and physical energy consumption is increased. Especially for mental workers, because the brain is in a state of high tension for a long time, it is very easy to cause brain hypoxia, cells lack endogenous oxygen, and symptoms such as dizziness, chest tightness, fatigue and drowsiness, slow reaction, and lack of concentration appear. In severe cases, it will affect normal study, work and life. Oxygen therapy can also be carried out through oxygen inhalation.

[0003] Publication No.: CN107174712A discloses a breathing device controlled by breathing, which has a simple structure and is easy to control. The sleeve connection between the nasal tube and the exhalation tube improves the sealing of the oxygen supply, so that the oxygen can be absorbed more fully, indirectly improving the utilization rate of oxygen, and can complete oxygen inhalation and exhalation at the same time. It is easy to use. The pressure in the nasal tube is detected by a flat film pressure sensor, and the electromagnetic control valve of the humidification tube is controlled to open and close in cooperation with the processor. It can effectively supply oxygen according to the patient's breathing frequency, and is more comfortable to use; Publication No.: CN115282415A discloses an oxygen supply device that supplies oxygen at the same frequency as breathing. The oxygen supply valve and the connecting belt are used to intermittently supply oxygen to the patient according to the patient's breathing frequency. On the one hand, it can reduce oxygen consumption, and on the other hand, it can improve the comfort of the patient when exhaling.

[0004] However, both of the above two devices have certain problems in actual use. Comparative Document 1 detects the pressure in the nasal tube through a flat film pressure sensor and uses an electromagnetic control valve to control the opening and closing. However, the flat film pressure sensor is arranged on the inner side of the nasal tube. When the user inhales, the electromagnetic control valve is in a closed state, and the pressure in the nasal tube does not change, so that the flat film pressure sensor cannot effectively sense, which makes it inconvenient for the electromagnetic control valve to effectively supply oxygen according to the user's breathing, and the existing flat film pressure sensor is not convenient to achieve a miniaturized state that can be inserted into the nostrils. Even if it can be done, the price will be relatively expensive; Comparative Document 2 adopts the combination of an oxygen supply valve and a connecting belt to intermittently supply oxygen to the patient according to the patient's breathing frequency. However, the connecting belt needs to be worn on the patient when in use. When the patient is exercising or performing other actions, the chest and abdomen will fluctuate, which will cause the position of the connecting belt to change and open the oxygen outlet hole, and then the oxygen release will be faster. In addition, if the connecting belt wants to work normally, it needs to be worn tightly on the patient, and the comfort is relatively poor, and the patient will resist.

[0005] Therefore, it is necessary to provide an oxygen delivery system and oxygen supply equipment with intelligent flow control function to solve the above technical problems. Summary of the invention

[0042] The invention provides an oxygen delivery system and oxygen supply equipment with intelligent flow control function.

[0043] First embodiment:

[0044] See also Figure 1 , Figure 2 and Figure 4 , an oxygen delivery system with intelligent flow control function, comprising an oxygen tank 1 and an intelligent cover 2;

[0045] The top of the smart cover 2 is respectively provided with a PCB board 3, a solenoid valve 4 and a battery 5, the battery 5 is electrically connected to the PCB board 3 and the solenoid valve 4, the PCB board 3 is electrically connected to the solenoid valve 4, the top of the PCB board 3 is connected to an air inlet pipe 6, the top of the solenoid valve 4 is connected to an air outlet pipe 7, the bottom of the solenoid valve 4 is connected to the oxygen tank 1 through a pipeline, the left ends of the air inlet pipe 6 and the air outlet pipe 7 are connected to a ventilation component 8, and the left side of the ventilation component 8 is connected to an oxygen absorption tube 9;

[0046] Preferably, the battery 5 is externally connected to a USB charging interface, through which the battery 5 can be charged. The top of the smart cover 2 is a prefabricated complete assembly, and the PCB board 3, the solenoid valve 4 and the battery 5 can be directly pressed onto the top of the smart cover 2.

[0047] The left end of the oxygen inhalation tube 9 is connected to an oxygen mask, a one-way valve is provided on the surface of the oxygen mask, and a breathing detection sensor is provided on the surface of the oxygen mask;

After the PCB board 3 detects it, the solenoid valve 4 is opened, and the oxygen in the oxygen tank 1 is released through the air outlet pipe 7 and the oxygen absorption tube 9 to the oxygen mask for oral and nose inhalation of oxygen. When the user stops inhaling, the air inlet pipe 6 no longer takes in air. After the PCB board 3 cannot detect the airflow, the solenoid valve 4 is closed, and the oxygen tank 1 stops releasing oxygen. When the user exhales, the gas is directly discharged into the air through the one-way valve on the oxygen mask. This system can greatly save the amount of oxygen used.

When in use, oxygen is released only when the person inhales, and the oxygen supply is stopped when the person exhales to save oxygen and avoid waste.

[0052] Second embodiment:

[0053] See also Figures 1 to 10 , an oxygen supply device with intelligent flow control function, comprising a mounting box 11, an opening mechanism 12, a lifting mechanism 13 and a limiting mechanism 14;

[0054] The opening mechanism 12 includes a box door 121 arranged at the front side of the installation box 11, and four draw rods 122 are fixedly arranged on the back of the box door 121. The surfaces of the four draw rods 122 are slidably connected with sliding sleeves 123. The surfaces of the four sliding sleeves 123 are fixedly connected to the inner wall of the installation box 11. Electromagnets 124 are arranged on both sides of the inner wall of the installation box 11. A pull rod 125 is fixedly arranged at the bottom of the back of the box door 121.

[0055] Please combine Figure 6 , Figure 7 and Figure 8 : De-energize the electromagnet 124 through the control panel 10, and then pull the box door 121 forward through the handle, so that the box door 121 can be pulled forward. During the pulling process, the draw rod 122 will slide forward in the sliding sleeve 123, and the pull rod 125 will also move forward. When the box door 121 is pulled out, the oxygen tank 1 can be installed.

[0056] The lifting mechanism 13 includes two slide rails 131 fixedly arranged at the bottom of the inner wall of the installation box 11, the surfaces of the two slide rails 131 are slidably connected with a sliding seat 132, the top of the sliding seat 132 is fixedly provided with two support plates 133, the opposite sides of the two support plates 133 are fixedly provided with a connecting plate 134, the front of the connecting plate 134 is fixedly connected to the back of the pull rod 125, four guide rods 135 are fixedly arranged at the bottom of the inner wall of the installation box 11, the surfaces of the four guide rods 135 are slidably connected with a mounting seat 136, the bottom of the mounting seat 136 is fixedly provided with two brackets 137, the inner sides of the two brackets 137 are rotatably connected with rollers 138;

[0057] Please combine Figure 8 When the box door 121 is pulled forward, the pull rod 125 drives the two support plates 133 to move forward through the connecting plate 134. The two support plates 133 move forward and drive the sliding seat 132 to slide forward on the surface of the slide rail 131. The movement of the two support plates 133 causes the mounting seat 136 to gradually slide downward on the surface of the guide rod 135.

[0058] Furthermore, when the box door 121 is pushed backward, the pull rod 125 moves backward, which drives the connecting plate 134 and the supporting plate 133 to move backward. When the supporting plate 133 moves backward, the bracket 137 is lifted upward by the roller 138. The movement of the two brackets 137 drives the mounting seat 136 to slide upward on the surface of the guide rod 135. When the oxygen tank 1 is placed on the top of the mounting seat 136, the mounting seat 136 moves upward, and the top of the oxygen tank 1 can be inserted into the smart cover 2 to form a sealed structure.

[0059] Preferably, the oxygen tank 1 is arranged on the top of the mounting seat 136 when in use, and a groove for cooperating with the slide rail 131 is provided on the inner side of the bottom of the sliding seat 132, and can slide on the surface of the slide rail 131, and a groove for cooperating with the guide rod 135 is provided on the inner side of the mounting seat 136.

[0060] The limiting mechanism 14 includes a vertical plate 141 fixedly arranged on the rear side of the top of the mounting seat 136, two sliding frames 142 are fixedly arranged on the back of the inner wall of the mounting box 11, the inner sides of the two sliding frames 142 are slidably connected with guide plates 143, the front sides of the two guide plates 143 are fixedly arranged with gear plates 144, the back side of the inner wall of the mounting box 11 is rotatably connected with a gear 145, the gear 145 is meshed with the two gear plates 144, and the front sides of the two gear plates 144 are fixedly arranged with limiting brackets 146;

[0061] Please combine Fig.10 : When the mounting seat 136 moves downward, it will drive the vertical plate 141 to move downward at the same time, and the vertical plate 141 moves downward to drive the gear 145 to rotate clockwise, and the gear 145 rotates clockwise to make the top gear plate 144 drive the limit bracket 146 to move rightward, and the bottom gear plate 144 drives the limit bracket 146 to move leftward. When the oxygen tank 1 is located at the top of the mounting seat 136, the two limit brackets 146 move to the separated side, so that the limit of the oxygen tank 1 can be cancelled, so as to facilitate the replacement and inflation of the oxygen tank 1;

[0062] Furthermore, when the mounting seat 136 moves upward, the vertical plate 141 is driven to move upward at the same time, and the movement of the vertical plate 141 causes the gear 145 to rotate counterclockwise. The gear 145 rotates counterclockwise, causing the two gear plates 144 to move to opposite sides. When the oxygen tank 1 is located on the top of the mounting seat 136, the two gear plates 144 drive the two limiting brackets 146 to limit the oxygen tank 1.

[0063] The inner sides of the four sliding sleeves 123 are respectively provided with sliding grooves used in cooperation with the four draw rods 122, the inner side of the box door 121 is provided with an iron block used in cooperation with the electromagnet 124, and the front side of the box door 121 is provided with a handle;

[0064] Preferably, the door 121 can be easily pulled out by providing a handle.

[0065] A gear block is disposed on the right side of the inner side of the vertical plate 141 , and the vertical plate 141 is meshed with the gear 145 through the gear block.

[0066] In this embodiment, compared with the existing oxygen supply equipment, after the oxygen tank 1 is placed on the top of the mounting seat 136, the box door 121 is pushed backward, and the box door 121 will drive the two support plates 133 to move backward through the pull rod 125 under the action of the connecting plate 134, and the mounting seat 136 and the oxygen tank 1 will be lifted up through the movement of the two support plates 133, so that the oxygen tank 1 and the smart cover 2 are tightly connected together, and the mounting seat 136 will simultaneously drive the vertical plate 141 to move upward during the movement, and the gear 145 will rotate counterclockwise through the movement of the vertical plate 141. The gear 145 rotates counterclockwise and the two gear plates 144 respectively drive the two limiting brackets 146 to move to the opposite side, thereby automatically limiting the oxygen tank 1 to prevent the oxygen tank 1 from shaking during use. The operation is simple and convenient, and the functions of closing the box door 121, docking the oxygen tank 1 with the smart cover 2 and automatically limiting the oxygen tank 1 can be achieved through a single action.

[0067] Third embodiment:

[0068] See also Figure 3 , Figure 4 , Figure 5 and Fig.11 A sealing protection mechanism 15 is provided on the left side of the installation box 11, and the sealing protection mechanism 15 includes a protective cover 151 provided on the left side of the installation box 11, two clamping frames 152 are fixedly provided on the left side of the inner wall of the protective cover 151, a through hole 153 is opened on the inner side of the protective cover 151, and two sliders 154 are fixedly provided on the right side of the protective cover 151, and the surfaces of the two sliders 154 are slidably connected to the inner side of the installation box 11, and the inner sides of the two sliders 154 are vertically slidably connected with sliding rods 155, and the two ends of the two sliding rods 155 are fixedly connected to the inner side of the installation box 11, and the surfaces of the two sliding rods 155 and the tops of the two sliders 154 are sleeved with springs 156;

[0069] Please combine Fig.11: When the oxygen tube 9 is connected to the ventilation component 8 through the through hole 153, the two sliders 154 slide downward on the surface of the sliding rod 155 through the elastic force of the two springs 156, and the sliding of the sliders 154 drives the protective cover 151 to move downward. When the protective cover 151 moves, it drives the clamping frame 152 to move downward. The clamping frame 152 moves downward to limit the joint position of the oxygen tube 9, so as to prevent the oxygen tube 9 from falling off during use;

[0070] Furthermore, when the oxygen tube 9 is pulled out, the elastic force of the spring 156 causes the two sliders 154 to slide downward on the surface of the sliding rod 155, and the two sliders 154 drive the protective cover 151 to move downward, so that the through hole 153 of the protective cover 151 is located away from the ventilation member 8, and the protective cover 151 can be used to seal the ventilation member 8, thereby preventing air and impurities from entering the air inlet pipe 6 and the air outlet pipe 7 through the ventilation member 8;

[0071] Preferably, the joint of the oxygen inhalation tube 9 is made of rubber material, which can form a sealing effect after being inserted into the ventilation component 8.

[0072] A limiting sleeve 16 is provided on the top of the mounting seat 136, the top of the smart cover 2 is fixedly connected to the top of the inner wall of the mounting box 11, the surface of the ventilation member 8 is fixedly connected to the inner side of the left side of the mounting box 11, a handrail 17 is fixedly provided on the back of the mounting box 11, and two universal wheels 18 are respectively provided on both sides of the bottom of the mounting box 11;

[0073] Preferably, by setting the limiting sleeve 16, the bottom of the oxygen tank 1 can be limited, and when the oxygen tank 1 is placed in the limiting sleeve 16, it can be accurately inserted into the smart cover 2 when it rises. By setting the armrest 17, it can provide support for people with walking difficulties. By setting the universal wheel 18, the device can be used without being restricted by the venue, and can be used in the ward or at home.

[0074] In this embodiment, after the oxygen absorption tube 9 is connected with the ventilation component 8, the protective cover 151 can drive the clamping frame 152 to move downward through the elastic force of the spring 156, and then the clamping frame 152 is used to limit the position of the oxygen absorption tube 9 to prevent the oxygen absorption tube 9 from falling off during use. When the connection between the oxygen absorption tube 9 and the ventilation component 8 is cancelled, the elastic force of the spring 156 can move the protective cover 151 downward, so that the ventilation component 8 is sealed by the protective cover 151 to prevent gas and dust from entering the air inlet pipe 6 and the air outlet pipe 7, which can effectively play a protective role.

[0075] Please refer to Figures 1 to 11The working principle of the oxygen delivery system and oxygen supply equipment with intelligent flow control function provided by the present invention is as follows:

[0076] Step S1, first cancel the power supply to the electromagnet 124 through the control panel 10, then pull the box door 121 forward through the handle, the movement of the box door 121 drives the draw rod 122 and the pull rod 125 to move forward, and then place the oxygen tank 1 on the top of the mounting seat 136 through the gap between the box door 121 and the mounting box 11. When placing, the oxygen tank 1 needs to be accurately placed in the limiting sleeve 16, and the oxygen tank 1 is in a vertical state, and the pipeline at the bottom of the solenoid valve 4 is connected to the oxygen tank 1;

[0077] Step S2, after the installation of the oxygen tank 1 is completed, the box door 121 is pushed backward by the handle, and the movement of the box door 121 drives the pull rod 125 to move backward. The pull rod 125 moves backward and pushes the two support plates 133 backward under the action of the connecting plate 134. The movement of the two support plates 133 causes the sliding seat 132 to slide backward on the surface of the slide rail 131, and the movement of the two support plates 133 will push the two rollers 138 upward, and the two The roller 138 then lifts the mounting seat 136 upwards through the bracket 137, so that the mounting seat 136 slides upwards on the surface of the guide rod 135. The movement of the mounting seat 136 drives the oxygen tank 1 to move upwards, so that the oxygen tank 1 is inserted into the smart cover 2, and a sealing effect is formed between the oxygen tank 1 and the smart cover 2. When the box door 121 is closed, the electromagnet 124 is started through the control panel 10, and the electromagnet 124 is used to adsorb the box door 121, so that the box door 121 is in a tightly closed state.

[0078] Step S3, the mounting base 136 moves upward and drives the vertical plate 141 to move upward, and the movement of the vertical plate 141 drives the gear 145 to rotate counterclockwise, and the gear 145 rotates counterclockwise and drives the two gear plates 144 to move to the opposite side, and the two gear plates 144 drive the two limit brackets 146 to move to the opposite side, respectively. When the oxygen tank 1 is plugged into the smart cover 2, the limit brackets 146 are used to limit the oxygen tank 1;

[0079] Step S4, after the oxygen tank 1 is installed, the protective cover 151 is slid upward, and then the oxygen absorption tube 9 is connected with the ventilation component 8 and the protective cover 151 is loosened. The two sliders 154 are made to slide downward on the surface of the sliding rod 155 by the elastic force of the two springs 156, and the protective cover 151 is driven to move downward by the sliding of the sliders 154. When the protective cover 151 moves, the clamping frame 152 is driven to move downward, and the clamping frame 152 moves downward to limit the joint position of the oxygen absorption tube 9;

[0080] Step S5, after completing the installation of the oxygen tank 1 and the oxygen absorption tube 9, the oxygen mask is worn on the user's mouth and nose. When the user inhales, there will be a weak airflow in the air inlet pipe 6. After the PCB board 3 detects it, the solenoid valve 4 is opened, and the oxygen in the oxygen tank 1 is released through the air outlet pipe 7 and the oxygen absorption tube 9 to reach the oxygen mask for the mouth and nose to inhale oxygen. When the user stops inhaling, the air inlet pipe 6 no longer takes in air. After the PCB board 3 cannot detect the airflow, the solenoid valve 4 is closed, and the oxygen tank 1 stops releasing oxygen. When the user exhales, the gas is directly discharged into the air through the one-way valve on the oxygen mask.
