By setting a positioning component, the number and volume of water chambers can be adjusted according to actual needs, which can not only meet the high-efficiency filtration needs when the air environment is poor, but also reduce the trouble of frequent water changes when the environment is good, thereby enhancing the versatility and practicality of the equipment. By setting a cleaning component, the attachments on the heat exchange box and the U-shaped long plate can be quickly removed, which significantly reduces the maintenance difficulty and cleaning cost of the equipment, and at the same time extends the service life of the equipment.

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, which has limited filtration effect and cannot dynamically adjust the filtration intensity according to the ambient air quality, resulting in insufficient filtration efficiency in environments with heavy air pollution. In environments with good air quality, the maintenance frequency may increase due to excessive filtration, and cleaning and maintenance are relatively cumbersome. In particular, the heat exchange tank is prone to accumulation of impurities and bacteria, which not only increases maintenance costs, but also may affect the service life of the equipment and the patient's respiratory safety. In addition, it lacks intelligent monitoring functions and cannot monitor key parameters such as gas temperature, humidity and flow rate in real time, making it difficult to meet the personalized needs of different patients.

DETAILED DESCRIPTION

[0030] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0032] A sealing slide 122 is movably provided on the lower surface of the heat exchange box 111, and an L-shaped side panel 123 is symmetrically fixed on the sealing slide 122. The L-shaped side panels 123 are slidably matched with the heat exchange box 111. Springs are provided between the heat exchange box 111 and the L-shaped side panels 123. An adjustment chamber is formed between the heat exchange box 111 and the sealing slide 122. In the initial position, the spring between the heat exchange box 111 and the L-shaped side panel 123 is not compressed. At this time, the sealing slide 122 is located directly below the heat exchange box 111, that is, a closed adjustment chamber is formed between the two.

[0033] A partition assembly is provided on the heat exchanger box 111, and the partition assembly includes a plurality of partition slides 119 uniformly slidably mounted on the heat exchanger box 111. Springs are symmetrically provided between the partition slides 119 located outside the heat exchanger box 111 and the heat exchanger box 111. The partition slides 119 divide the regulating chamber into a plurality of water flow chambers. Air guide holes 130 are provided on the partition slides 119. The axis of the air guide hole 130, the axis of the air inlet pipe 105, and the center line of the connection between the air guide pipe 110 and the heat exchanger box 111 are all on the same straight line. The connection between the air guide hole 130, the air inlet pipe 105, the air guide pipe 110 and the heat exchanger box 111 is all above the highest water level line in the water flow chamber.

[0034] In the initial position, the springs between the heat exchange box 111 and the partition slide 119 are not compressed. At this time, the surface of the partition slide 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 119 divides the regulating chamber into multiple water flow chambers.

[0035] The heat exchange box 111 is provided with a guide assembly, which includes a guide slide 115. The guide slide 115 is symmetrically fixed with an L-shaped side plate 121, and the L-shaped side plate 121 is slidably matched with the heat exchange box 111. A cleaning slide 116 is fixedly installed on the square scraper 124. A cleaning screw 117 and a pitch-adjusting screw 135 are rotatably installed on the heat exchange box 111. The cleaning screw 117 and the cleaning slide 116 constitute a spiral pair, and the pitch-adjusting screw 135 and the corresponding L-shaped side plate 121 constitute a spiral pair. A pitch-adjusting motor 136 is fixedly installed on the outside of the heat exchange box 111, and the output shaft of the pitch-adjusting motor 136 is fixedly connected to the pitch-adjusting screw 135.

[0036] A plurality of U-shaped long plates 128 are evenly fixed on the guide slide 115. A heating plate is provided on the outer side of the U-shaped long plates 128, and the interior of the water flow chamber is heated by the heating plate. The U-shaped long plates 128 are slidably matched 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 flow chamber. The U-shaped long plates 128 are respectively located inside the corresponding water flow chambers. When the U-shaped long plates 128 are respectively engaged with the heat exchange box 111 and the partition slide 119, there is no gap at the contact position between the two, and the air guide holes 130 are located on the inner side of the corresponding U-shaped long plates 128.

[0037] In the initial position, the guide slide 115 is located at the position closest to the heat exchange box 111. At this time, the lower section of the U-shaped long plate 128 is in contact with the upper surface of the sealing slide 122. At this time, a closed chamber is formed between the U-shaped long plate 128 and the corresponding partition slide 119 or the heat exchange box 111, that is, an air supply pipe is formed between the U-shaped long plate 128 and the corresponding partition slide 119 or the heat exchange box 111.

[0038] Starting the pitch-adjusting motor 136 drives the pitch-adjusting screw rod 135 to rotate, so that the corresponding L-shaped side plate 121 moves upward, thereby causing the guide slide 115 to move upward, and the U-shaped long plate 128 on the guide slide 115 all move upward synchronously, that is, there is a gap between the U-shaped long plate 128 and the sealing slide 122, and by starting the air 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 of the area between the heat exchange box 111 and the corresponding U-shaped long plate 128 moves downward, and the area between the heat exchange box 111 and the corresponding U-shaped long plate 128 The water level line on the outside moves upward, and eventually the water level line of the area between the heat exchange box 111 and the corresponding U-shaped long plate 128 is lower than the water level line on the outside of 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, and then moves to above the water level line of the area, and enters the chamber in the area between the adjacent U-shaped long plate 128 and the partition slide 119 again. The above steps are repeated, and finally the gas is discharged from the air inlet pipe 105 after being baptized by multiple water chambers. A disposable breathing tube is installed at the end of the air inlet pipe 105, and then the user wears the breathing tube. Under the action of the vortex air pump 108, assisted breathing for the user is achieved.

[0039] A plurality of floating plates 127 are evenly and slidingly installed on the inner side of the heat exchange box 111. The floating plates 127 are respectively located on the inner sides of the corresponding water flow chambers. Air holes are evenly arranged on the floating plates 127. The floating plates 127 are used to reduce the fluctuation of the water level in the water flow chamber.

[0040] Start the distance adjustment motor 136 to continue driving the guide slide 115 to move upward, so that the U-shaped long plate 128 moves downward, thereby adjusting the position of the lower end of the air supply pipe formed between the U-shaped long plate 128 and the corresponding partition slide 119 or the heat exchange box 111 in the water flow chamber, so that the contact time between the gas and the liquid inside the water flow chamber can be controlled according to demand.

[0041] A positioning assembly is provided on the base plate 101, and the positioning assembly is used to adjust the positions of the partitioning slide 119 and the sealing slide 122. The positioning assembly includes a positioning slide 145 slidably mounted on the base plate 101, a positioning screw rod 143 is rotatably mounted on the base plate 101, a positioning motor 144 is fixedly mounted on the base plate 101, the output shaft of the positioning motor 144 is fixedly connected to the positioning screw rod 143, the positioning screw rod 143 and the positioning motor 144 constitute a spiral pair, a positioning pull plate 141 is slidably mounted on the positioning slide 145, a positioning screw rod 2 146 is rotatably mounted on the positioning slide 145, the positioning screw rod 2 146 and the positioning pull plate 141 constitute a spiral pair, a positioning motor 2 147 is fixedly mounted on the positioning slide 145, the output shaft of the positioning motor 2 147 is fixedly connected to the positioning screw rod 2 146, and the axis of the positioning screw rod 2 146 is perpendicular to the axis of the positioning screw rod 143.

[0042] Start the positioning motor 144 to drive the positioning screw 143 to rotate, so that the positioning slide 145 moves along the axis of the positioning screw 143, and start the positioning motor 2 147 to drive the positioning screw 2 146, so that the positioning pull plate 141 moves along the axis of the positioning screw 2 146.

[0043] A positioning push plate 2 150 is fixedly provided on the lower end surface of the partition slide 119, and a positioning push plate 142 is fixedly provided on the sealing slide 122. The positioning pull plate 141 is used to push the positioning push plate 142 and the positioning push plate 2 150 to move separately. A limiting ratchet 140 is fixedly provided on the positioning push plate 2 150, and a limiting slide 148 is slidably installed on the bottom plate 101. A spring is provided between the limiting slide 148 and the bottom plate 101. In the initial position, the spring between the bottom plate 101 and the limiting slide 148 is not compressed. The two sides of the limiting ratchet 2 149 are parallel to the two sides of the corresponding limiting ratchet 140. A plurality of limiting ratchet 2 149 are evenly provided on the limiting slide 148. When the limiting ratchet 140 and the corresponding limiting ratchet 2 149 are engaged, a ratchet mechanism is formed. The limiting ratchet 140 and the limiting ratchet 2 149 are used to limit the position of the corresponding partition slide 119.

[0044] In the initial position, the partition slides 119 are all located at the position farthest from the positioning screw rod 143. At this time, the limiting ratchet bar 140 is not engaged with the corresponding limiting ratchet bar 2 149, and the positioning pull plate 141 is also located at the position farthest from the positioning screw rod 143. When it is necessary to combine two adjacent water flow chambers into one water flow chamber, the positioning motor 144 is started to drive the positioning slide 145 to move, so that the positioning pull plate 141 moves to the inner side of the positioning push plate 2 150 corresponding to the partition slide 119 between the two water flow chambers to be adjusted, and then the positioning motor 2 147 is started to make the positioning pull plate 141 move in the direction close to the positioning motor 2 147. Under the action of the positioning push plate 2 150, the partition slide 1 19 moves in the direction close to the positioning screw 143, and the spring between the partition slide 119 and the heat exchange box 111 is compressed, which eventually causes the partition slide 119 to move to the position closest to the positioning screw 143. At this time, the surface of the partition slide 119 on the inner side of the heat exchange box 111 and the corresponding surface on the inner side of the heat exchange box 111 are on the same plane, and at this time, the limiting ratchet 140 and the corresponding limiting ratchet 2 149 corresponding to the partition slide 119 are engaged to form a ratchet mechanism. Under the action of the limiting ratchet 140 and the limiting ratchet 2 149, the partition slide 119 cannot move in the direction away from the positioning screw 143, thereby realizing the merging of the water flow chambers on both sides of the partition slide 119.

[0045] Repeat the above steps to achieve separate adjustment of each partition slide 119, and move the partition slide 119 to the position closest to the positioning screw rod 143, start the positioning motor 144 and the positioning motor 2 147 to move the positioning pull plate 141 to the inner side of the positioning push plate 142, and then start the positioning motor 2 147 to move the positioning pull plate 141 toward the positioning motor 2 147. Under the action of the positioning push plate 142, the sealing slide 122 moves toward the positioning motor 2 147, and the spring between the L-shaped side plate 2 123 and the heat exchange box 111 is compressed, which eventually moves the sealing slide 122 to the position closest to the positioning screw rod 143. At this time, the lower end of the heat exchange box 111 is in an open state.

[0046] A limit slide 118 is slidably mounted on the bottom plate 101, a limit screw 131 is rotatably mounted on the bottom plate 101, the limit screw 131 and the limit slide 118 form a spiral pair, a limit motor 132 is fixedly mounted on the bottom plate 101, the output shaft of the limit motor 132 is fixedly connected to the limit screw 131, a limit strip 120 is symmetrically arranged on the limit slide 118, and a square plate 120 is provided on the partition slide 119 to cooperate with the limit strip 120. The two limiting strips 120 are respectively used to limit the positions of the partition slide 119 when it is inside the heat exchange box 111 and when the partition slide 119 is outside the heat exchange box 111. A limiting strip 2 133 is also fixedly provided on the limiting slide 118. The limiting strip 2 133 and the sealing slide 122 slide together when they are engaged. The limiting strip 2 133 is used to limit the position of the sealing slide 122. The limiting slide 118 is also used to push the limiting ratchet 2 149 to move.

[0047] In the initial position, the limiting slide 118 is located at the farthest position from the limiting motor 132. At this time, the limiting strip 2 133 and the sealing slide 122 are in an engaged state. The sealing slide 122 cannot move freely under the action of the limiting strip 2 133. The partition slides 119 farthest from the adjusting screw rod 143 are all engaged with the limiting strip 120 farthest from the adjusting screw rod 143. The partition slides 119 closest to the adjusting screw rod 143 are all engaged with the limiting strip 120 closest to the adjusting screw rod 143. Under the action of the limiting strip 120, the partition slides 119 cannot move freely.

[0048] When it is necessary to adjust the position of the partition slide 119 and the sealing slide 122, the limit motor 132 is started to drive the limit screw 131 to rotate, so that the limit slide 118 moves in the direction close to the limit motor 132, and finally the limit strip 1 120 is disengaged from the partition slide 119 and the limit strip 2 133 is disengaged from the sealing slide 122, that is, the restriction on the position of the partition slide 119 and the sealing slide 122 is released. At this time, the limit slide 118 is released to the limit slide 148, and the limit slide 118 continues to move in the direction close to the limit motor 132. The limit slide 118 pushes the limit slide 148 to move, that is, the limit ratchet 2 149 is disengaged from the limit ratchet 1 140, that is, the limit ratchet 2 149 releases the restriction on the position of the partition slide 119, and the partition slide 119 can move to the position farthest from the adjustment screw 143 under the action of the spring between the partition slide 119 and the heat exchange box 111.

[0049] The heat exchange box 111 is provided with a cleaning assembly, which includes a square scraper 124 slidably mounted inside the heat exchange box 111, and the square scraper 124 is used to clean the inside of the heat exchange box 111. The U-shaped long plates 128 are slidably matched with the square scraper 124, and the square scraper 124 is used to scrape off the attachments on the surface of the U-shaped long plates 128. A cleaning slide 116 is fixedly mounted on the square scraper 124, and a cleaning screw 117 is rotatably mounted on the heat exchange box 111. The cleaning screw 117 and the cleaning slide 116 constitute a spiral pair, and the cleaning slide 116 and the guide slide 115 slidably cooperate. A cleaning motor 134 is fixedly mounted on the outside of the heat exchange box 111, and a cleaning screw 117 is also rotatably mounted on the outside of the heat exchange box 111. The cleaning screw 117 and the cleaning slide 116 constitute a spiral pair, and the output shaft of the cleaning motor 134 is fixedly connected to the cleaning screw 117.

[0050] Multiple limiting square rods 125 are evenly and slidingly installed on both sides of the limiting square rod 125. The limiting square rods 125 are used to prevent the floating plate 127 from blocking the air guide hole 130. Multiple electromagnets 126 are evenly and fixedly installed on both sides of the lower end surface of the heat exchange box 111. The electromagnets 126 are used to limit the position of the corresponding limiting square rods 125.

[0051] When the square scraper 124 is not in use, the square scraper 124 is located at the position farthest from the lower surface of the base plate 101. At this time, the upper end of the limiting square rod 125 contacts the upper surface inside the heat exchange box 111. Under the action of the heat exchange box 111, the limiting square rod 125 is located on the square scraper 124 at the position closest to the lower surface of the heat exchange box 111. At this time, the lower end of the limiting square rod 125 is used to limit the position of the floating plate 127, thereby preventing the floating plate 127 from blocking the flow of the air guide hole 130.

[0052] When it is necessary to clean the inside of the heat exchange box 111, first move the partition slide 119 and the sealing slide 122 to the position closest to the adjustment screw rod 143, then start the distance adjustment screw rod 135 to move the guide slide 115 to the position closest to the heat exchange box 111, and then start the cleaning motor 134 to drive the cleaning screw rod 117 to rotate, so that the cleaning slide 116 moves downward and the square scraper 124 moves downward synchronously. Under the action of the square scraper 124, the attachments on the inner surface of the heat exchange box 111 and the U-shaped long plate 128 are scraped off and cleaned, and finally the lower surface of the square scraper 124 and the lower surface of the heat exchange box 111 are on the same plane, and under the action of the electromagnet 126, the limiting square rod 125 moves relative to the square scraper 124, and the limiting square rod 125 moves on the square scraper 124 to the position farthest from the lower surface of the bottom plate 101. At this time, the lower end face of the limiting square rod 125 and the lower surface of the square scraper 124 are on the same plane. When the limiting square rod 125 slides relative to the square scraper 124, the attachments on the surface of the limiting square rod 125 are scraped off, and then the sealing slide 122 moves in the direction away from the adjusting screw rod 143. Under the action of the sealing slide 122, the attachments on the surface of the square scraper 124 are scraped off. In the process of the sealing slide 122 moving in the direction close to the adjusting screw rod 143, the heat exchange box 111 scrapes off the attachments on the upper surface of the sealing slide 122.

[0053] A transposition slide 129 is slidably mounted on the L-shaped side panel 121. The length of the transposition slide 129 is greater than the length of the sealing slide 122. A transposition screw rod 139 is rotatably mounted on the sealing slide 122. A transposition motor 138 is fixedly mounted on the sealing slide 122. The output shaft of the transposition motor 138 is fixedly connected to the transposition screw rod 139. The transposition screw rod 139 and the transposition slide 129 form a spiral pair. A solenoid valve 137 is fixedly mounted on the transposition slide 129. The solenoid valve 137 is used to fill and drain water into each water flow chamber. Multiple sensors are provided inside each water flow chamber of the heat exchange box 111. The sensors are used to monitor the temperature, water level and gas flow rate inside the water flow chamber.

[0054] Start the transposition motor 138 to drive the transposition screw 139 to rotate, so that the transposition slide 129 slides relative to the sealing slide 122, thereby adjusting the position of the solenoid valve 137 so that the solenoid valve 137 engages with different water flow chambers, and water is injected into and drained from different water flow chambers through the solenoid valve 137.

[0055] The bottom plate 101 is fixed with a housing 102, which is used to protect the internal components. The bottom plate 101 is also movably provided with a waste water tank 103, a liquid injection pipe 106 is fixedly provided on the housing 102, an electric three-way valve 112 is provided between the waste water tank 103, the liquid injection pipe 106 and the solenoid valve 137, a sealing slide 122 is fixedly installed on the housing 102, a drain pipe 113 is fixedly installed on the housing 102, and a The water pump, the solenoid valve 137 is connected to the water pump, and a water diversion pipe 114 is arranged between the water pump and the electric three-way valve 112. The three ends of the electric three-way valve 112 are fixedly connected to the injection pipe 106, the drainage pipe 113, and the water diversion pipe 114 respectively. The water diversion pipe 114 is connected to the injection pipe 106 and the drainage pipe 113 respectively through the electric three-way valve 112. The ends of the air outlet pipe 104, the air inlet pipe 105, and the liquid injection pipe 106 are all located on the outside of the shell 102.

[0056] When it is necessary to inject water into the water passage chamber, the water supply pipe and the injection pipe 106 are connected, and the water diversion pipe 114 and the injection pipe 106 are connected through the electric three-way valve 112, that is, the solenoid valve 137 and the injection pipe 106 are connected, so that the water passage chamber is injected with water by controlling the solenoid valve 137 and the water pump. When it is necessary to discharge the water in the water passage chamber, the solenoid valve 137 and the drain pipe 113 are connected through the electric three-way valve 112, so that the solenoid valve 137 and the water pump are controlled to discharge the water in the water passage chamber into the waste water tank 103.

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

[0058] In areas with poor air environment, continuous filtration of gas can be achieved through continuous water-passing chambers, thereby ensuring 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 accommodate more water and reduce the frequency of frequent replacement, which is especially suitable for long-term ventilation.

[0059] When it is necessary to clean the inside of the heat exchange box 111, the partition slide 119 and the sealing slide 122 are moved to the position closest to the positioning screw 143 through the adjustment component, and then the guide slide 115 is moved to the position closest to the heat exchange box 111, and then the square scraper 124 is used to scrape off the attachments on the heat exchange box 111 and the square scraper 124, and then the sealing slide 122 is used to scrape off the auxiliary attachments on the square scraper 124, thereby achieving rapid cleaning of the inside of the heat exchange box 111 and the attachments on the square scraper 124.

[0060] The present invention is not limited to the above-mentioned specific embodiments. Various modifications made by technicians in the relevant technical field based on the above-mentioned conception without creative work are all within the scope of protection of the present invention.
