Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to a ventilator with intelligent monitoring and self-cleaning functions. Background Art

[0002] As an important medical device, ventilators are widely used in clinical treatment and home care. However, existing ventilators use a single water filtration method, with limited filtration effect and unable to dynamically adjust the filtration intensity according to the ambient air quality. This results in insufficient filtration efficiency in environments with heavy air pollution, and may increase the maintenance frequency due to excessive filtration in environments with good air quality. Cleaning and maintenance are relatively cumbersome. In particular, the heat exchange tank is prone to accumulating impurities and bacteria, which not only increases the maintenance cost, but may also affect the service life of the device and the respiratory safety of patients. Moreover, they lack intelligent monitoring functions and cannot real-time monitor key parameters such as gas temperature, humidity, and flow rate, making it difficult to meet the personalized needs of different patients. Therefore, the present invention provides a ventilator with intelligent monitoring and self-cleaning functions. Summary of the Invention

Detailed implementation manners

[0030] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention.

[0031] Embodiment: Refer to Figures 1-15 , a ventilator with intelligent monitoring and self-cleaning functions, including a bottom plate 101, a vortex air pump 108 and a heat exchange box 111 are fixedly installed on the bottom plate 101, an intake motor 109 is fixedly installed on the vortex air pump 108, and the intake motor 109 is used to drive the fan blades inside the vortex air pump 108 to rotate. An outlet pipe 104 is fixedly installed on the intake port of the vortex air pump 108, and a filter 107 is fixedly installed on the outlet pipe 104. The air entering the vortex air pump 108 through the outlet pipe 104 is filtered by the filter 107. A guide pipe 110 is fixedly arranged between the outlet of the vortex air pump 108 and the heat exchange box 111. An inlet pipe 105 is fixedly arranged on the heat exchange box 111. The connection between the guide pipe 110 and the heat exchange box 111 is arranged opposite to the connection between the inlet pipe 105 and the heat exchange box 111.

[0032] A sealing slide plate 122 is movably arranged on the lower surface of the heat exchange box 111. L-shaped side plates II 123 are symmetrically and fixedly arranged on the sealing slide plate 122. The L-shaped side plates II 123 are all in sliding fit with the heat exchange box 111. Springs are arranged between the heat exchange box 111 and the L-shaped side plates II 123. An adjustment chamber is formed between the heat exchange box 111 and the sealing slide plate 122. In the initial position, the springs between the heat exchange box 111 and the L-shaped side plates II 123 are not compressed. At this time, the sealing slide plate 122 is located directly below the heat exchange box 111, that is, a sealed adjustment chamber is formed between the two at this time.

[0033] A partition component is arranged on the heat exchange box 111. The partition component includes a plurality of partition slide plates 119 that are evenly slidably installed on the heat exchange box 111. Springs are symmetrically arranged between the area of the partition slide plates 119 outside the heat exchange box 111 and the heat exchange box 111. The partition slide plates 119 divide the adjustment chamber into a plurality of water passing chambers. Air guide holes 130 are arranged on the partition slide plates 119. The axes of the air guide holes 130, the axis of the inlet pipe 105, and the center line of the connection between the guide pipe 110 and the heat exchange box 111 are all on the same straight line. The air guide holes 130, the inlet pipe 105, the connection between the guide pipe 110 and the heat exchange box 111 are all above the highest water level line in the water passing chambers.

[0034] In the initial position, the springs between the heat exchange box 111 and the partition slide plates 119 are not compressed. At this time, the surface of the partition slide plate 119 farthest from the heat exchange box 111 is located at the position closest to the heat exchange box 111, that is, at this time, the partition slide plates 119 divide the adjustment chamber into a plurality of equal water passing chambers.

[0035] A flow guiding component is arranged on the heat exchange box 111. The flow guiding component includes a flow guiding slide plate 115. Symmetrically fixed on the flow guiding slide plate 115 are L-shaped side plates I 121, and the L-shaped side plates I 121 are all in sliding fit with the heat exchange box 111. A cleaning slide frame 116 is fixedly installed on the square scraping plate 124. A cleaning lead screw 117 and an adjustment lead screw 135 are rotatably installed on the heat exchange box 111. The cleaning lead screw 117 and the cleaning slide frame 116 form a screw pair, and the adjustment lead screw 135 and the corresponding L-shaped side plate I 121 form a screw pair. An adjustment motor 136 is fixedly installed on the outer side of the heat exchange box 111, and the output shaft of the adjustment motor 136 is fixedly connected to the adjustment lead screw 135.

[0036] A plurality of U-shaped long plates 128 are evenly and fixedly arranged on the flow guiding slide plate 115. Heating plates are arranged on the outer sides of the U-shaped long plates 128. The inside of the water passing chamber is heated by the heating plates. The U-shaped long plates 128 are all in sliding fit with the heat exchange box 111. The U-shaped long plates 128 are used to limit the movement path of the gas entering the water passing chamber. The U-shaped long plates 128 are respectively located inside the corresponding water passing chambers. When the U-shaped long plates 128 are respectively joined with the heat exchange box 111 and the partition slide plate 119, there is no gap at the contact position between the two. The air guide holes 130 are located inside the corresponding U-shaped long plates 128.

[0037] In the initial position, the flow guiding slide plate 115 is located at the position closest to the heat exchange box 111. At this time, the lower cross sections of the U-shaped long plates 128 are all in contact with the upper surface of the sealing slide plate 122. At this time, a sealed chamber is formed between the U-shaped long plates 128 and the corresponding partition slide plate 119 or the heat exchange box 111, that is, an air supply pipeline is formed between the U-shaped long plates 128 and the corresponding partition slide plate 119 or the heat exchange box 111.

[0038] Start the pitch-adjusting motor 136 to drive the pitch-adjusting lead screw 135 to rotate, causing the corresponding L-shaped side plate 121 to move upward, and further causing the flow guide slide plate 115 to move upward. The U-shaped long plates 128 on the flow guide slide plate 115 all move upward synchronously, that is, creating a gap between the U-shaped long plate 128 and the sealing slide plate 122. By starting the intake motor 109, the fan blades inside the vortex air pump 108 rotate, and the external air enters the vortex air pump 108 along the air outlet pipe 104 and then enters the area formed between the heat exchange box 111 and the corresponding U-shaped long plate 128 through the air guide pipe 110. Under the action of air pressure, the water level line in the area between the heat exchange box 111 and the corresponding U-shaped long plate 128 moves downward, and the water level line outside the area between the heat exchange box 111 and the corresponding U-shaped long plate 128 moves upward. Finally, the water level line in the area between the heat exchange box 111 and the corresponding U-shaped long plate 128 is lower than the water level line outside the area between the heat exchange box 111 and the corresponding U-shaped long plate 128. At this time, the gas enters the water outside the area between the heat exchange box 111 and the corresponding U-shaped long plate 128 from the lower end of the U-shaped long plate 128, then moves above the water level line of this area, and enters the chamber in the area between the adjacent U-shaped long plate 128 and the partition slide plate 119 again. Repeat the above steps, and finally the gas is discharged from the intake pipe 105 after being baptized by multiple water chambers. Install a disposable breathing tube at the end of the intake pipe 105, and then the user wears this breathing tube. Under the action of the vortex air pump 108, the auxiliary breathing of the user is realized.

[0039] A plurality of floating plates 127 are evenly and slidably installed inside the heat exchange box 111. The floating plates 127 are respectively located inside the corresponding water chambers. The floating plates 127 are evenly provided with air holes, and the floating plates 127 are used to weaken the fluctuation degree of the water level line in the water chambers.

[0040] Start the pitch-adjusting motor 136 to continue driving the flow guide slide plate 115 to move upward, that is, causing the U-shaped long plates 128 to all move downward, so as to adjust the position of the lower end of the air supply pipeline formed between the U-shaped long plate 128 and the corresponding partition slide plate 119 or the heat exchange box 111 inside the water chamber, so that the contact time between the gas and the liquid inside the water chamber can be controlled according to requirements.

[0041] A positioning adjustment component is provided on the bottom plate 101. The positioning adjustment component is used to adjust the positions of the partition sliding plate 119 and the sealing sliding plate 122. The positioning adjustment component includes a positioning adjustment sliding plate 145 slidably mounted on the bottom plate 101. A first positioning adjustment screw rod 143 is rotatably mounted on the bottom plate 101. A first positioning adjustment motor 144 is fixedly mounted on the bottom plate 101. The output shaft of the first positioning adjustment motor 144 is fixedly connected to the first positioning adjustment screw rod 143. The first positioning adjustment screw rod 143 and the first positioning adjustment motor 144 form a screw pair. A positioning adjustment pull plate 141 is slidably mounted on the positioning adjustment sliding plate 145. A second positioning adjustment screw rod 146 is rotatably mounted on the positioning adjustment sliding plate 145. The second positioning adjustment screw rod 146 and the positioning adjustment pull plate 141 form a screw pair. A second positioning adjustment motor 147 is fixedly mounted on the positioning adjustment sliding plate 145. The output shaft of the second positioning adjustment motor 147 is fixedly connected to the second positioning adjustment screw rod 146. The axis of the second positioning adjustment screw rod 146 is perpendicular to the axis of the first positioning adjustment screw rod 143.

[0042] Start the first positioning adjustment motor 144 to drive the first positioning adjustment screw rod 143 to rotate, which causes the positioning adjustment sliding plate 145 to move along the axis of the first positioning adjustment screw rod 143. Start the second positioning adjustment motor 147 to drive the second positioning adjustment screw rod 146, which causes the positioning adjustment pull plate 141 to move along the axis of the second positioning adjustment screw rod 146.

[0043] A second positioning adjustment push plate 150 is fixedly provided on the lower end surface of the partition sliding plate 119. A first positioning adjustment push plate 142 is fixedly provided on the sealing sliding plate 122. The positioning adjustment pull plate 141 is used to push the first positioning adjustment push plate 142 and the second positioning adjustment push plate 150 to move separately. A first limiting ratchet bar 140 is fixedly provided on each of the second positioning adjustment push plates 150. A limiting sliding plate 148 is slidably mounted on the bottom plate 101. A spring is provided between the limiting sliding plate 148 and the bottom plate 101. The spring between the bottom plate 101 and the limiting sliding plate 148 is not compressed in the initial position. The two sides of the second limiting ratchet bar 149 are parallel to the two sides of the corresponding first limiting ratchet bar 140. A plurality of second limiting ratchet bars 149 are evenly provided on the limiting sliding plate 148. When the first limiting ratchet bar 140 and the corresponding second limiting ratchet bar 149 are engaged, a ratchet mechanism is formed. The first limiting ratchet bar 140 and the second limiting ratchet bar 149 are used to limit the position of the corresponding partition sliding plate 119.

[0044] In the initial position, the partition slide plates 119 are all located at the positions farthest from the position-adjusting lead screw 143. At this time, the first limit ratchet bars 140 are not engaged with the corresponding second limit ratchet bars 149, and the position-adjusting pull plate 141 is also located at the position farthest from the position-adjusting lead screw 143. When it is necessary to combine two adjacent water passage chambers into one water passage chamber, start the first position-adjusting motor 144 to drive the position-adjusting slide plate 145 to move, so that the position-adjusting pull plate 141 moves to the inside of the second position-adjusting push plate 150 corresponding to the partition slide plate 119 between the two water passage chambers to be adjusted. Then start the second position-adjusting motor 147 to make the position-adjusting pull plate 141 move in the direction close to the second position-adjusting motor 147. Under the action of the second position-adjusting push plate 150, this partition slide plate 119 moves in the direction close to the position-adjusting lead screw 143, and the spring between this partition slide plate 119 and the heat exchange box 111 is compressed. Finally, this partition slide plate 119 moves to the position closest to the position-adjusting lead screw 143. At this time, the surface of this partition slide plate 119 located inside the heat exchange box 111 and the corresponding surface inside the heat exchange box 111 are on the same plane, and at this time, the first limit ratchet bar 140 corresponding to this partition slide plate 119 and the corresponding second limit ratchet bar 149 are engaged to form a ratchet mechanism. Under the action of the first limit ratchet bar 140 and the second limit ratchet bar 149, at this time, the partition slide plate 119 cannot move in the direction away from the position-adjusting lead screw 143, that is, the combination of the water passage chambers on both sides of this partition slide plate 119 is realized.

[0045] Repeat the above steps to realize the individual adjustment of each partition slide plate 119. When the partition slide plate 119 moves to the position closest to the position-adjusting lead screw 143, start the first position-adjusting motor 144 and the second position-adjusting motor 147 to make the position-adjusting pull plate 141 move to the inside of the first position-adjusting push plate 142. Then start the second position-adjusting motor 147 to make the position-adjusting pull plate 141 move in the direction close to the second position-adjusting motor 147. Under the action of the first position-adjusting push plate 142, the sealing slide plate 122 moves in the direction close to the second position-adjusting motor 147, and the spring between the second L-shaped side plate 123 and the heat exchange box 111 is compressed. Finally, the sealing slide plate 122 moves to the position closest to the position-adjusting lead screw 143. At this time, the lower end of the heat exchange box 111 is in an open state.

[0046] A limiting slide carriage 118 is slidably mounted on a bottom plate 101, a limiting lead screw 131 is rotatably mounted on the bottom plate 101, the limiting lead screw 131 and the limiting slide carriage 118 form a screw pair, a limiting motor 132 is fixedly mounted on the bottom plate 101, an output shaft of the limiting motor 132 is fixedly connected to the limiting lead screw 131, limiting strip plates I 120 are symmetrically arranged on the limiting slide carriage 118, square holes adapted to the limiting strip plates I 120 are arranged on the partition sliding plates 119, the two limiting strip plates I 120 are respectively used for restricting the positions of the partition sliding plates 119 when they are inside and outside the heat exchange box 111, a limiting strip plate II 133 is also fixedly arranged on the limiting slide carriage 118, the limiting strip plate II 133 is in sliding fit when engaged with the sealing sliding plate 122, the limiting strip plate II 133 is used for restricting the position of the sealing sliding plate 122, and the limiting slide carriage 118 is also used for pushing a limiting ratchet bar II 149 to move.

[0047] In the initial position, the limiting slide carriage 118 is located at the position farthest from the limiting motor 132. At this time, the limiting strip plate II 133 and the sealing sliding plate 122 are in an engaged state, and the sealing sliding plate 122 cannot move freely under the action of the limiting strip plate II 133. The partition sliding plates 119 farthest from the adjusting lead screw I 143 are all engaged with the limiting strip plates I 120 farthest from the adjusting lead screw I 143, and the partition sliding plates 119 closest to the adjusting lead screw I 143 are all engaged with the limiting strip plates I 120 closest to the adjusting lead screw I 143. Under the action of the limiting strip plates I 120, the partition sliding plates 119 cannot move freely.

[0048] When the positions of the partition sliding plates 119 and the sealing sliding plate 122 need to be adjusted, the limiting motor 132 is started to drive the limiting lead screw 131 to rotate, so that the limiting slide carriage 118 moves in the direction close to the limiting motor 132. Finally, the limiting strip plates I 120 are disengaged from the partition sliding plates 119 and the limiting strip plate II 133 is disengaged from the sealing sliding plate 122, that is, the restrictions on the positions of the partition sliding plates 119 and the sealing sliding plate 122 are released. At this time, the limiting slide carriage 118 abuts against the limiting sliding plate 148.

A plurality of sensors are arranged inside each water passing chamber of the heat exchange box 111. The sensors are used for monitoring the temperature, water level line, and gas flow rate inside the water passing chamber.

[0054] Start the transposition motor 138 to drive the transposition screw rod 139 to rotate, that is, to make the transposition slide plate 129 slide relative to the sealing slide plate 122, so as to adjust the position of the electromagnetic valve 137, make the electromagnetic valve 137 engage with different water passing chambers, and realize the injection of water and drainage of different water passing chambers through the electromagnetic valve 137.

An electric three-way valve 112 is arranged between the waste water tank 103, the liquid injection pipe 106 and a solenoid valve 137. A sealing slide plate 122 is fixedly installed on the housing 102. A drain pipe 113 is fixedly installed on the housing 102. A water pump is also fixedly installed on the housing 102. The solenoid valve 137 is communicated with the water pump. A water guiding pipe 114 is arranged between the water pump and the electric three-way valve 112. The three end parts of the electric three-way valve 112 are fixedly communicated with the liquid injection pipe 106, the drain pipe 113 and the water guiding pipe 114 respectively.

[0056] When it is necessary to inject water into the water passing chamber, connect the water replenishing pipeline with the liquid injection pipe 106. Make the water guiding pipe 114 communicate with the liquid injection pipe 106 through the electric three-way valve 112, that is, make the solenoid valve 137 communicate with the liquid injection pipe 106. Thus, the water passing chamber can be injected with water by controlling the solenoid valve 137 and the water pump. When it is necessary to drain the water in the water passing chamber, make the solenoid valve 137 communicate with the drain pipe 113 through the electric three-way valve 112. Thus, control the solenoid valve 137 and the water pump to drain the water in the water passing chamber into the waste water tank 103.

[0057] Working principle: Adjust the number of water passing chambers and the position of the lower end part of the air supply pipeline formed between the U-shaped long plate 128 and the partition slide plate 119 according to the requirements. Then connect the disposable breathing tube with the air inlet pipe 105. Heat the inside of the water passing chamber through the heating plate on the U-shaped long plate 128. Through the sensors inside the water passing chamber, the temperature, water level line and gas flow rate inside the water passing chamber are monitored in real time. Then inject air into the heat exchange box 111 through a vortex air pump 108. Under the action of multiple water passing chambers, the air is continuously filtered, humidified and heated. Medicine liquid can also be injected into the water passing chamber, so that the breathing gas can carry the medicine liquid.

[0058] In areas with poor air environment, continuous filtration of gas can be realized through continuous water passing chambers, so as to ensure the quality of breathing gas. In places with better air environment, by reducing the number of water passing chambers and increasing the volume of the water passing chambers, the increased volume can hold more water, reducing the frequent replacement frequency, especially suitable for the state of long-term ventilation.

[0059] When it is necessary to clean the inside of the heat exchange box 111, the partition slide plate 119 and the sealing slide plate 122 are moved to the position closest to the position adjusting screw rod 143 through the position adjusting component, and then the diversion slide plate 115 is moved to the position closest to the heat exchange box 111. Then, the attachments on the heat exchange box 111 and the square scraping plate 124 are scraped off by the square scraping plate 124, and then the attachments on the square scraping plate 124 are scraped off by the sealing slide plate 122, that is, the inside of the heat exchange box 111 and the attachments on the square scraping plate 124 are quickly cleaned.
