Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of respiratory assistance devices, and in particular to a respiratory assistance device for patients with lung diseases. Background Art
[0002] In modern clinical medicine, ventilators, as an effective means of artificially assisting or replacing the patient's spontaneous ventilation function, have been widely used in respiratory failure caused by various reasons, anesthesia respiratory management during major surgery, respiratory support therapy and emergency resuscitation, and occupy a very important position in the field of modern medicine.
[0003] In the respiratory support system composed of a ventilator, a humidifier is a crucial component of the system. It is primarily used to heat and humidify the delivered gas to simulate the physiological environment of the human respiratory tract and prevent dry gas from directly entering the lower respiratory tract, which can lead to drying of the airway mucosa, impaired ciliary motility, and increased risk of sputum crust formation and airway obstruction. Common humidifiers achieve humidification by inserting the respiratory tube into a humidification water tank. The humidification effect is achieved by either oxygen carrying water as it passes through the water layer, or by heating water to generate water vapor that mixes with oxygen. However, this humidification effect is limited and cannot meet the high humidity requirements of the ventilator, making it unsuitable for use in patients who are sensitive to airway dryness (such as those undergoing endotracheal intubation).
[0004] After searching, the Chinese invention patent with publication number CN101252966B discloses a respiratory assistance device, in particular, the respiratory assistance device is controlled to have a drying cycle so as to dry the tube that supplies gas to the user and prevent germs from hiding in the tube. The drying cycle is preferably automatically controlled by an internal controller in the device. Then, it can also be manually controlled by pressing a button on the device. The drying cycle is preferably started at the end of the user's treatment period. This application generates water vapor by heating a water tank to achieve the effect of heating and humidifying oxygen, but the humidification speed of this method is slow and the efficiency is low. It is difficult to provide high humidity to quickly relieve the symptoms of dry airways, and therefore it is not conducive to patients who are sensitive to dry airways. Summary of the Invention
[0005] In view of the above-mentioned prior art, the present invention provides a respiratory assistance device for patients with lung diseases, and the main technical problem to be solved is how to ensure the humidification efficiency of oxygen.
[0006] To achieve the above-mentioned purpose, the technical solution of the embodiment of the present invention is implemented as follows: A respiratory assistance device for patients with lung diseases includes a humidifier, a mask and a ventilator. Ventilation pipelines are provided between the humidifier, the mask and the ventilator. The humidifier includes a base and a body. The body includes a water tank, a water pipe and an air tank. The water pipe is arranged between the water tank and the air tank. The water tank is provided with an atomizing sheet and a water guide mechanism for spraying into the water pipe. The water pipe is provided with rifling for generating a swirling flow in the mist. The air tank is provided with a diverter block for dispersing the mist. The ventilator mixes the mist with oxygen by introducing oxygen into the air tank.
[0007] Furthermore, both ends of the water pipe are fixedly connected to the water tank and the air tank respectively. A partition is fixedly connected to the top inner side of the water tank. The partition is annular, and the atomizing sheet is fixedly connected to the inner side of the partition.
[0008] Furthermore, a connecting tube is provided through the middle of the bottom end of the water tank, a sealing cover is threadedly connected to the outer side of the bottom end of the connecting tube, a socket is fixedly connected to the inner wall of the bottom end of the sealing cover, and the water guide mechanism includes a cotton swab inserted into the socket.
[0009] Furthermore, a number of support blocks are fixedly connected at equal distances to the inner bottom of the gas bin, and a diverter block is fixedly connected to the top of the support block. The diverter block is in the shape of an inverted cone, and a heating wire for heating water mist is provided inside the diverter block.
[0010] Furthermore, a window is provided at the top of the gas bin, and a cover is fixedly connected to the top of the gas bin outside the window. A cotton block is provided on the inner side of the cover, and the diameter of the cotton block is larger than the diameter of the window.
[0011] Furthermore, a connecting pipe is provided between the cover shell and the water tank, and a cotton strip is provided inside the connecting pipe. The top end of the cotton strip abuts against the cotton block, and the bottom end of the connecting pipe and the cotton strip is located at the top end of one side of the water tank.
[0012] Furthermore, an air inlet and an air outlet are respectively provided at both ends of one side of the air bin. The air inlet of the air bin is fixedly connected to an air inlet pipe, and the air outlet of the air bin is fixedly connected to an air outlet pipe. Both the air inlet pipe and the air outlet pipe are located in the circumferential direction of the air bin.
[0013] Furthermore, the height of the air inlet is greater than the height of the air outlet, and a guide plate is provided between the air inlet and the air outlet on the inner wall of the air storage close to the air inlet pipe and the air outlet pipe. The guide plate is in an inclined state with the lower end close to the air inlet and the high end close to the air outlet.
[0014] Furthermore, the base is in an "L" shape, and a connecting shaft is provided at the top of the inner wall of one side of the base, and one end of the connecting shaft is rotatably connected to the water pipe through a damping rotation.
[0015] Furthermore, a sleeve is fixedly connected to the top of the inner wall of one side of the base, the connecting shaft is inserted in the sleeve, a threaded through hole is opened on one side of the sleeve, the sleeve is threadedly connected to a bolt at the threaded through hole, and a slot adapted to the bolt is opened at one end of the connecting shaft.
[0016] The beneficial effects of the present invention are: 1. The humidifier of the present application achieves humidification by spraying water mist onto the oxygen. During this process, the rifling can cause the water mist to generate a swirl in the air chamber. The collision of the rotating mist flow with the oxygen entering the air chamber can make the oxygen and water mist mix more efficiently and evenly, thereby ensuring that the humidification speed of the device is fast and efficient, and thus it can provide oxygen with higher humidity to the ventilator to quickly relieve the symptoms of dry airway of the patient. In addition, when the water mist enters the air chamber, the diverter block can promote the water mist to move along the inner wall of the air chamber to ensure that it can quickly mix with the airflow entering from the circumferential direction, thereby further ensuring the humidification efficiency. 2. During the operation of this device, the cotton swab can transfer the water in the water tank to the atomizing piece and spray it into the air tank in the form of atomizer, while the cotton block can absorb the excess water mist in the air tank and then return it to the water tank through the cotton sliver. Therefore, this device can circulate water and avoid the accumulation of water mist in the air tank and ventilation pipes, which gradually forms water droplets and increases ventilation resistance and poor air supply. 3. The body of the present application is rotatably connected to the base. Therefore, when water needs to be added to the water tank, you only need to turn the body upside down, twist the sealing cover and remove it to open the water tank. It is also convenient to replace the cotton swab to maintain its hygiene and water conduction efficiency.
[0017] 4. Bolts are provided to connect the sleeve and the connecting shaft. After removing the bolts, the body and the base can be separated to facilitate disinfection and sterilization of the entire body, thereby maintaining the cleanliness and hygiene of the medical device.

DETAILED DESCRIPTION
[0020] The technical solutions of the present invention are further described in detail below with reference to the accompanying drawings and specific embodiments. Unless otherwise defined, all technical and scientific terms used herein have the same meanings as those commonly understood by those skilled in the art to which the present invention pertains. The terms used in the present invention description are for the purpose of describing specific embodiments only and are not intended to limit the present invention.
[0021] Example 1 Refer to the attached Figure 1-4 The present application provides a respiratory assistance device for lung patients, including a humidifier 1, a mask 2 and a ventilator 3. The ventilator 3 can adopt an existing model, such as the VIVO3 invasive and non-invasive integrated ventilator. A ventilation pipeline is provided between the humidifier 1, the mask 2 and the ventilator 3. An electric heating wire is arranged on the outside of the ventilation pipeline to maintain the temperature of the supplied oxygen. The humidifier 1 includes a base 101 and a body 102. The body 102 is hourglass-shaped, that is, the water tank 1021 and the air tank 1023 are both truncated cone-shaped. The diameter of the water pipe 1022 is smaller than that of the water tank 1021 and the air tank 1023. The body 102 includes a water tank 1021 and an air tank 1023. 21. Water pipe 1022 and air tank 1023. The water pipe 1022 is arranged between the water tank 1021 and the air tank 1023. The water tank 1021 is provided with an atomizing sheet 1141 and a water guide mechanism for spraying into the water pipe 1022. The water pipe 1022 is provided with rifling 111 for making the mist flow produce a swirl. The air tank 1023 is provided with a diverter block 109 for dispersing the mist flow. The ventilator 3 mixes the mist flow with the oxygen by introducing oxygen into the air tank 1023. The counterclockwise rotating mist flow and the clockwise rotating air flow collide, so that the two can contact more evenly and mix more fully, thereby ensuring the efficiency of humidifying the oxygen.
[0022] Preferably, a connecting tube 112 is provided through the middle of the bottom end of the water tank 1021, and a sealing cover 113 is threadedly connected to the outer side of the bottom end of the connecting tube 112. The inner wall of the bottom end of the sealing cover 113 is fixedly connected to a socket 1131, and the water guide mechanism includes a cotton swab 1132 inserted into the socket 1131.
[0023] Preferably, the base 101 is in an "L" shape, and a connecting shaft 107 is provided at the top of the inner wall of one side of the base 101. One end of the connecting shaft 107 is rotatably connected to the water pipe 1022 through a damping rotation.
[0024] When using this device to provide respiratory assistance to patients with lung diseases, the body 102 can be turned upside down, and the sealing cover 113 can be twisted to remove it. Then, sterile water, distilled water, or medical purified water can be injected into the water tank 1021 through the connecting tube 112. After installing the cotton swab 1132 on the socket 1131, the sealing cover 113 can be tightened again on the outside of the connecting tube 112. Then, the body 102 can be turned again to return it to the normal direction. Preferably, an air inlet 1031 and an air outlet 1051 are respectively opened at both ends of one side of the air bin 1023, and the air bin 1023 is fixedly connected to an air inlet pipe 103 at the air inlet 1031, and the air bin 1023 is fixedly connected to an air outlet pipe 105 at the air outlet 1051, and the air inlet pipe 103 and the air outlet pipe 105 are both located in the circumferential direction of the air bin 1023.
[0025] Then, the mask 2 can be worn on the patient's mouth and nose, and the humidifier 1 and the ventilator 3 are both powered on and started. At this time, the ventilator 3 will deliver oxygen to the humidifier 1 through the ventilation pipeline, so the oxygen will enter the air chamber 1023 from the air inlet pipe 103. Since the air inlet pipe 103 is located in the circumference of the air chamber 1023, the oxygen will flow along the inner wall of the air chamber 1023 in a circular trajectory. Preferably, the height of the air inlet 1031 is greater than the height of the air outlet 1051, and a guide plate 115 is provided between the air inlet 1031 and the air outlet 1051 on the inner wall of the air tank 1023 close to the air inlet pipe 103 and the air outlet pipe 105. The guide plate 115 is in an inclined state with the lower end close to the air inlet 1031 and the high end close to the air outlet 1051. After oxygen enters the air tank 1023 from the air inlet 1031, it will flow in the direction away from the guide plate 115 and on the horizontal plane where the air tank 1023 is located. When it reaches the guide plate 115 along the inner wall of the air tank 1023, it will descend along its surface to the horizontal plane where the air outlet 1051 is located, and finally flow out from the air outlet 1051, thereby extending the distance and time of oxygen flowing in the air tank 1023 to ensure that it can be fully mixed with the water mist.
[0026] In the above process, when the airflow flows to the guide plate 115, its tilted state causes the height of the airflow to drop, thereby changing the flow trajectory of the airflow from a circular ring to a spiral downward, so that when the airflow flows to the air outlet 1051, it will flow out of the air outlet pipe 105 and be transported to the mask 2 by the ventilation pipeline for the patient to breathe and supply oxygen; Preferably, both ends of the water pipe 1022 are fixedly connected to the water tank 1021 and the air tank 1023 respectively. A partition 114 is fixedly connected to the inner top of the water tank 1021. The partition 114 is annular, and the atomizing plate 1141 is fixedly connected to the inner side of the partition 114.
[0027] Preferably, several support blocks 110 are fixedly connected at equal distances at the inner bottom end of the air chamber 1023, and the diverter block 109 is fixedly connected to the top of the support block 110. The diverter block 109 is in the shape of an inverted cone. A heating wire for heating water mist is provided inside the diverter block 109. A casing is provided on the outside of the water pipe 1022. An electrically connected controller and power supply are provided in the casing. The heating wire and the atomizing plate 1141 are electrically connected to the controller and the power supply. A safety valve is provided on the air chamber 1023 to prevent the air pressure from being too high or too low to ensure the safety of patient ventilation.
[0028] At the same time, the cotton swab 1132 can conduct the water in the water tank 1021 to the atomizing plate 1141, which then atomizes the water and sprays it into the water pipe 1022. With the help of the rifling 111 on its inner wall, the water mist generates a swirl in the opposite direction of the above-mentioned air flow and diffuses into the air tank 1023. The presence of the diverter block 109 can also divert the water mist, causing it to rotate and flow along the inner wall of the air tank 1023. Therefore, the air vortex and the water mist vortex in opposite directions collide in the air chamber 1023, allowing the oxygen and the water mist to fully contact and evenly mix, thereby achieving the effect of highly efficient oxygen humidification. As a result, the air outlet pipe 105 can output high-humidity oxygen to the mask 2, thereby quickly alleviating the patient's symptoms of dry airways. Preferably, a window 108 is provided at the top of the air chamber 1023, and the top of the air chamber 1023 is fixedly connected to a cover 104 outside the window 108. A cotton block 1041 is provided on the inner side of the cover 104, and the diameter of the cotton block 1041 is larger than the diameter of the window 108.
[0029] During the operation of the device, the cotton block 1041 can absorb the excess water mist in the air chamber 1023 and transport it back to the water chamber 1021 through the cotton strip 1061 to ensure full utilization of resources and avoid the accumulation of liquid water droplets in the air chamber 1023 and the ventilation pipeline due to the accumulation of water mist, which in turn increases the ventilation resistance and causes poor air supply. Preferably, a connecting tube 106 is provided between the cover shell 104 and the water tank 1021 , and a cotton strip 1061 is provided inside the connecting tube 106 , the top of the cotton strip 1061 abuts against the cotton block 1041 , and the bottom ends of the connecting tube 106 and the cotton strip 1061 are at the top of one side of the water tank 1021 .
[0030] In addition, the connecting tube 106 can not only protect the tampon 1061 to prevent it from being contaminated by the outside world, but also connect the water tank 1021 and the air tank 1023, thereby ensuring that after the water in the water tank 1021 is consumed, the air pressure inside it can still be balanced.
[0031] Example 2 Refer to the attached Figure 5 The present application provides a respiratory assistance device for patients with lung diseases. Compared with Example 1, in order to facilitate the cleaning and disinfection of the fuselage 102, a sleeve 1011 is fixedly connected to the top of the inner wall of one side of the base 101, and the connecting shaft 107 is inserted into the sleeve 1011. A threaded through hole is provided on one side of the sleeve 1011, and a bolt 1012 is threadedly connected to the sleeve 1011 at the threaded through hole. A card slot 1071 adapted to the bolt 1012 is provided at one end of the connecting shaft 107.
[0032] After using the device, the bolt 1012 can be twisted to adjust its outward movement until the bolt 1012 leaves the slot 1071, and the connecting shaft 107 can be pulled to make it fall off from the sleeve 1011. At this time, the fuselage 102 can be removed for cleaning and disinfection.
[0033] The above are merely specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any modifications or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in this invention should be included in the scope of protection of the present invention. The scope of protection of the present invention should be based on the scope of protection of the claims.
