Description

Technical Field

[0001] The present invention relates to the technical field of humidifiers, in particular to a nebulizing humidifier for a breathing machine. Background Art

[0002] In the modern medical field, ventilators are an important life support device and are widely used in the treatment of patients with various respiratory disorders. When the human respiratory tract breathes normally, it will heat and humidify the inhaled air to a suitable temperature and humidity to protect the respiratory mucosa, promote gas exchange, and facilitate the discharge of sputum. However, when patients rely on ventilators to assist breathing, if the delivered gas is not heated and atomized and humidified, the dry and cold gas directly enters the respiratory tract, which may cause dryness of the respiratory mucosa, weakened ciliary movement, and viscous sputum that is difficult to discharge, and even cause complications such as respiratory inflammation and infection.

[0003] Therefore, adding a heated atomizing humidifier to the gas delivery pipeline of the ventilator can effectively heat the gas to a temperature close to human body temperature and atomize the moisture into tiny particles so that it can be fully mixed with the gas, thereby providing warm and moist gas to the patient;

[0004] When the ventilator is idle, the mask usually needs to be disassembled, which will cause the end of the delivery tube to be exposed. This exposure not only makes it easy for dust and impurities to enter the tube, but more seriously, it provides favorable conditions for the growth of bacteria, especially for the ventilator pipeline equipped with a heated atomizing humidifier, because the temperature of the gas delivered at the end is relatively high, and the warm and humid environment is more conducive to the reproduction and growth of bacteria;

[0005] In view of this, we propose a nebulizer humidifier for a ventilator. Summary of the invention

[0006] The purpose of the present invention is to provide a nebulizer humidifier for a respirator to solve the problems raised in the above background technology.

[0007] To achieve the above object, the present invention provides a nebulizer humidifier for a respirator, comprising a nebulizer body, the nebulizer body being mounted at the gas output end of the respirator body, the respirator body comprising a base, a control member being placed on the top of the base, a bracket being mounted on the side end of the control member, the bracket being used to suspend and store a gas delivery pipe for delivering gas;

[0008] One end of the air delivery pipe away from the control unit is connected to the atomizer body, and the other end of the atomizer body can be mounted with a breathing mask;

[0009] The atomizer body includes an atomizing mechanism and a connecting mechanism, wherein the atomizing mechanism can heat, atomize and humidify the gas transported by the gas pipe, and the connecting mechanism includes a thin-walled transport pipe installed between the atomizing mechanism and the breathing mask;

[0010] When the heated gas is transported along the thin-walled delivery tube to the interior of the breathing mask, it can drive the thin-walled delivery tube to expand and enlarge the inner diameter. When the atomization mechanism stops heating the atomizing gas, the thin-walled delivery tube cools down and the inner diameter shrinks, which can reduce the entry of dust and impurities into the interior of the gas delivery tube.

[0011] As a further improvement of the present technical solution, the atomizing mechanism comprises a heating atomizing humidifier body connected to one end of the gas supply pipe away from the control component, and inner walls at both ends of the heating atomizing humidifier body are fixedly connected with sealing fittings.

[0012] As a further improvement of the technical solution, the connection mechanism further includes a flow balancing fan arranged inside the thin-walled delivery pipe, and the flow balancing fan is located at one end of the thin-walled delivery pipe away from the heating atomizing humidifier body, and the flow balancing fan is connected to the inner wall of the thin-walled delivery pipe through a mounting assembly;

[0013] One end of the thin-walled delivery pipe close to the flow-evening fan is clamped at the delivery hole of the breathing mask, and a fixing ring is fixedly connected to the surface of one end of the thin-walled delivery pipe close to the flow-evening fan, and the fixing ring is made of elastic material.

[0014] As a further improvement of the present technical solution, the installation assembly includes an inner groove opened in the middle of both sides of the flow-equalizing fan, and movable rods are slidably provided inside the two inner grooves, and the ends of the two movable rods away from the inner grooves are both in contact with the inner wall of the thin-walled conveying pipe.

[0015] As a further improvement of the technical solution, an insulation ring is fixedly connected to one end of the heating atomizing humidifier body close to the air pipe, and the other side of the insulation ring is fixedly connected to the end of the air pipe.

[0016] As a further improvement of the technical solution, the inner wall of the thin-walled conveying pipe is provided with two installation point holes, the interiors of the two installation point holes are fixedly connected with fixed blocks, and the ends of the two movable rods away from the flow-balancing fan are respectively fixedly connected to the surfaces of the two fixed blocks.

[0017] As a further improvement of the technical solution, the heating atomizing humidifier body and the surface of the thin-walled delivery tube are sleeved with an elastic outer sleeve belt.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. In the ventilator atomizing humidifier, the atomizing mechanism connected to the end of the gas pipe away from the control unit can effectively heat the gas transported by the gas pipe, and at the same time achieve the effect of atomizing humidification, increase the humidity and temperature of the gas, and make it reach an ideal state more suitable for human inhalation;

[0020] 2. In the respirator atomizing humidifier, the heated and humidified gas can be delivered to the inside of the breathing mask by means of a connecting mechanism arranged between the atomizing mechanism and the breathing mask. At the same time, the heated gas can also be cooled by means of this connecting mechanism, so that the gas is in a relatively comfortable temperature range when inhaled into the human body, thereby reducing the damage to the respiratory tract caused by excessive heating temperature. In addition, the connecting mechanism can also realize the gas diversion function, so that the gas flows evenly into the inside of the breathing mask, thereby improving the comfort of use;

[0021] 3. In the nebulizer humidifier of the respirator, the thin-walled delivery tube is made of silicone tube. When the delivered gas is heated by the atomization mechanism, the thin-walled delivery tube will expand due to the heat, causing the inner diameter of the tube to expand. The expansion of the inner diameter can effectively reduce the resistance to gas flow, significantly improve the gas delivery effect, and allow the gas to flow more smoothly; when the respirator body and the atomization mechanism are out of use, the thin-walled delivery tube is at room temperature and will retract to its original state. At this time, the inner diameter is relatively small. During the period when the respirator body is idle, this reduction in the inner diameter can reduce the entry of dust and impurities into the pipeline to a certain extent.

[0036] The following will be combined with the accompanying drawings in the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] Example

[0038] See also Figure 1 , Figure 2 and Figure 3 As shown, the purpose of this embodiment is to provide a nebulizer humidifier for a respirator, including a nebulizer body 2, which is installed at the gas output end of the respirator body 1, and the respirator body 1 includes a base 11, a control member 12 is placed on the top of the base 11, and a bracket 13 is installed on the side end of the control member 12. The bracket 13 is used to suspend and store a gas delivery pipe 14 for conveying gas, and one end of the gas delivery pipe 14 away from the control member 12 is connected to the nebulizer body 2, and the other end of the nebulizer body 2 can be installed with a breathing mask 15. The nebulizer body 2 includes The atomizing mechanism 21 and the connecting mechanism 22, the atomizing mechanism 21 can heat, atomize and humidify the gas transported by the air pipe 14, the connecting mechanism 22 includes a thin-walled delivery tube 221 installed between the atomizing mechanism 21 and the breathing mask 15, when the heated gas is transported to the inside of the breathing mask 15 along the thin-walled delivery tube 221, it can drive the thin-walled delivery tube 221 to expand and enlarge the inner diameter, when the atomizing mechanism 21 stops heating the atomizing gas, the thin-walled delivery tube 221 cools down and reduces the inner diameter, which can reduce the dust and impurities from entering the inside of the air pipe 14.

[0039] First, the specific structure of the atomizing mechanism 21 is disclosed. The atomizing mechanism 21 includes a heating atomizing humidifier body 211 connected to the end of the gas delivery pipe 14 away from the control member 12. The inner walls of both ends of the heating atomizing humidifier body 211 are fixedly connected with sealing fittings 212. Figure 7 As shown, the end of the air delivery pipe 14 is connected to the heating type atomizing humidifier body 211. When the gas passes through the heating type atomizing humidifier body 211 during transportation, the airflow can be effectively heated, humidified and atomized, so that the airflow delivered to the breathing mask 15 is the gas after humidification and heating treatment, and both ends of the heating type atomizing humidifier body 211 are tightly connected with the sealing fitting 212, which improves the installation sealing of the heating type atomizing humidifier body 211, effectively reduces the leakage of gas during the transmission process, and ensures the stability of the gas flow and pressure, wherein the sealing fitting 212 can be made of silicone rubber.

[0040] The working principle of the heated atomizing humidifier body 211 is mainly as follows: the liquid is heated to boiling point through the internal heating element to generate water vapor, and at the same time, the water vapor is broken up into tiny droplets by means of high-speed airflow or ultrasonic waves to form a mist. These mist particles are fully mixed with the passing airflow, so that the airflow carries a large number of tiny droplets, thereby achieving heating, humidification and atomization of the airflow, and finally outputting an airflow with suitable temperature and humidity and containing atomized particles. Generally speaking, the heating temperature of the heated atomizing humidifier body 211 used by the ventilator body 1 can be adjusted according to the situation where it needs to be used, generally between 30°C and 50°C. The liquid inside the heated atomizing humidifier body 211 can use the medicine that the user needs to use.

[0041] Next, the specific structure of the connection mechanism 22 is disclosed. The connection mechanism 22 also includes a flow balancing fan 223 disposed inside the thin-walled delivery tube 221, and the flow balancing fan 223 is located at one end of the thin-walled delivery tube 221 away from the heating atomizing humidifier body 211, and the flow balancing fan 223 is connected to the inner wall of the thin-walled delivery tube 221 through a mounting assembly 224;

[0042] One end of the thin-walled delivery tube 221 close to the flow-evening fan 223 is clamped at the delivery hole of the breathing mask 15 , and a fixing ring 222 is fixedly connected to the surface of one end of the thin-walled delivery tube 221 close to the flow-evening fan 223 , and the fixing ring 222 is made of elastic material.

[0043] Combination Figure 4It can be seen that the thin-walled delivery tube 221 is installed between the heated atomizing humidifier body 211 and the breathing mask 15. When the gas has not passed through the heated atomizing humidifier body 211, the thin-walled delivery tube 221 is in an original state, and the end of the thin-walled delivery tube 221 away from the heated atomizing humidifier body 211 can be connected to the breathing mask 15 through the fixing ring 222, which can improve the installation sealing of the thin-walled delivery tube 221, reduce the possibility of gas leakage to a certain extent, and ensure the stability and effectiveness of gas delivery, wherein the connection between the fixing ring 222 and the breathing mask 15 can be connected by Velcro adhesion, and the fixing ring 222 is preferably made of rubber;

[0044] See also Figure 5 When the thin-walled delivery tube 221 delivers heated gas, the hot gas can drive the thin-walled delivery tube 221 to expand, so that its inner diameter is enlarged. The enlarged inner diameter can effectively reduce the resistance to gas flow, significantly improve the gas delivery effect, and allow the gas to flow more smoothly. During the operation of the ventilator body 1, the thin-walled delivery tube 221 delivers the airflow to the inside of the breathing mask 15. With the delivery power of the airflow, the flow-equalizing fan 223 inside the thin-walled delivery tube 221 can be driven to rotate. With the operation of the flow-equalizing fan 223, on the one hand, it can play an auxiliary cooling role for the airflow, reducing the situation where the patient's inhalation effect is affected by overheating of the airflow. On the other hand, the flow-equalizing fan 223 can also divert the gas, so that the gas flows evenly into the inside of the breathing mask 15, thereby improving the comfort of the user;

[0045] When the thin-walled delivery pipe 221 delivers heated gas, the hot gas can drive the thin-walled delivery pipe 221 to expand, so that its inner diameter is enlarged, because the thin-walled delivery pipe 221 is made of silicone tube material, and silicone has the characteristic of thermal expansion. When the hot gas is delivered, the thin-walled delivery pipe 221 is heated, the thermal motion of the silicone molecules is intensified, and the atomic distance increases, resulting in the volume expansion of the material. For the thin-walled silicone tube, this expansion is obvious in the tube diameter direction, so that the inner diameter of the pipe is enlarged;

[0046] Combination Figure 6 As shown, when the ventilator body 1 is not in use, the breathing mask 15 is disassembled, and the ventilator body 1 is not in use, so that the heated atomizing humidifier body 211 will also stop running, and the thin-walled delivery tube 221 will stop delivering the heated airflow, so that the thin-walled delivery tube 221 shrinks to its original state. At this time, the flow-equalizing fan 223 installed inside the thin-walled delivery tube 221 close to the breathing mask 15 will also stop flipping, and the opening of the thin-walled delivery tube 221 can be auxiliaryly blocked to reduce dust from entering the thin-walled delivery tube 221. Before the ventilator body 1 is used again, the end of the thin-walled delivery tube 221 close to the flow-equalizing fan 223 is disinfected and cleaned.

[0047] Since the inner diameter of the thin-walled delivery pipe 221 can change with the temperature of the conveying gas, and the flow-equalizing fan 223 is installed inside the thin-walled delivery pipe 221, in view of this, in order to improve the installation stability of the flow-equalizing fan 223, the specific structure of the installation component 224 is disclosed, and the installation component 224 includes an inner groove 2241 opened in the middle of both sides of the flow-equalizing fan 223, and movable rods 2242 are slidably provided inside the two inner grooves 2241, and the ends of the two movable rods 2242 away from the inner grooves 2241 are both in contact with the inner wall of the thin-walled delivery pipe 221.

[0048] See also Figure 8 It can be seen that both ends of the flow-balancing fan 223 are carefully provided with inner grooves 2241, and the interior of the inner grooves 2241 is slidably equipped with movable rods 2242. When the thin-walled delivery tube 221 delivers a relatively high-temperature airflow and thereby produces an expansion phenomenon, the movable rods 2242 will follow the thin-walled delivery tube 221 to extend. At this time, the other ends of the two movable rods 2242 can slide inside the inner grooves 2241. In this way, the flow-balancing fan 223 will not produce excessive displacement, thereby making it easier for the flow-balancing fan 223 to achieve relatively stable operation and ensure that it can function continuously and stably.

[0049] Since the working principle of the heated atomizing humidifier body 211 is to evaporate the liquid by heating to drive the gas to form mist particles, the heated atomizing humidifier body 211 will generate a certain amount of heat during use. Therefore, in order to reduce the heat transferred to the gas pipe 14 when the heated atomizing humidifier body 211 is in use, thereby affecting the use of the gas pipe 14, the heated atomizing humidifier body 211 is fixedly connected to one end of the gas pipe 14 close to the gas pipe 14 with an insulation ring 3, and the other side of the insulation ring 3 is fixedly connected to the end of the gas pipe 14.

[0050] The improvements are: See Figure 3 Combined with Figure 7 As shown, an insulation ring 3 is connected between one end of the heating type atomizing humidifier body 211 close to the air pipe 14 and the air pipe 14. The insulation ring 3 can effectively block and isolate the heat generated during the use of the heating type atomizing humidifier body 211, significantly reduce the heat transferred to the air pipe 14, effectively ensure the overall service life of the air pipe 14, enable it to work stably for a long time, and reduce the risk of damage to the air pipe 14 due to overheating.

[0051] If the end of the movable rod 2242 is directly installed on the inner wall of the thin-walled conveying tube 221, then the soft thin-walled conveying tube 221 will find it difficult to provide sufficient rigid support for the flow-equalizing fan 223. This situation will reduce the energy utilization efficiency and affect the normal operation of the flow-equalizing fan 223. Therefore, in order to further enhance the rotation effect of the flow-equalizing fan 223, two installation point holes 51 are opened on the inner wall of the thin-walled conveying tube 221, and the interiors of the two installation point holes 51 are fixedly connected with fixed blocks 5, and the ends of the two movable rods 2242 away from the flow-equalizing fan 223 are respectively fixedly connected to the surfaces of the two fixed blocks 5.

[0052] The improvement is: according to Figure 3 and Figure 8 It can be seen that two installation point holes 51 are symmetrically opened on the inner wall of the thin-walled conveying pipe 221, and fixed blocks 5 are arranged inside the two installation point holes 51, and the ends of the two movable rods 2242 away from the inner groove 2241 are fixedly connected to the inside of the fixed blocks 5. When the thin-walled conveying pipe 221 expands, the two fixed blocks 5 will move accordingly. In addition, the fixed blocks 5 are made of hard plastic material, which can play a certain supporting role for the flow-balancing fan 223, thereby improving the energy utilization rate of the flow-balancing fan 223 driven by the airflow.

[0053] Considering that the thin-walled delivery tube 221 can be replaced or disassembled for disinfection and cleaning, the thin-walled delivery tube 221 and the heated atomizing humidifier body 211 are movably connected. Therefore, in order to further improve the sealing of the connection between the thin-walled delivery tube 221 and the heated atomizing humidifier body 211, the surfaces of the heated atomizing humidifier body 211 and the thin-walled delivery tube 221 are sleeved with an elastic outer sleeve band 4.

[0054] The improvements are: See Figure 3 Combined with Figure 7 As shown, an elastic outer sleeve band 4 is sleeved between the heating type atomizing humidifier body 211 and the thin-walled delivery tube 221. The elastic outer sleeve band 4 can give full play to its elastic properties to effectively seal the installation gap between the thin-walled delivery tube 221 and the heating type atomizing humidifier body 211, which can not only prevent gas leakage from the gap and ensure the stability and efficiency of gas delivery, but also block external impurities and dust from entering the interior through the gap to keep the interior of the equipment clean.

[0055] In summary, the working principle of this scheme is as follows: when the ventilator body 1 starts running, the heating atomizing humidifier body 211 can be controlled to operate. When the gas passes through the heating atomizing humidifier body 211 during the transportation process, the airflow can be effectively heated, humidified and atomized. When the thin-walled delivery tube 221 transports the heated gas, the hot gas can drive the thin-walled delivery tube 221 to expand, so that its inner diameter is enlarged. The enlarged inner diameter can effectively reduce the resistance to gas flow, significantly improve the gas transportation effect, and allow the gas to flow more smoothly. During the operation of the ventilator body 1, the thin-walled delivery tube 221 delivers the airflow to the inside of the breathing mask 15. With the delivery power of the airflow, the flow-equalizing fan 223 inside the thin-walled delivery tube 221 can be driven to rotate. With the operation of the flow-equalizing fan 223, on the one hand, it can play an auxiliary cooling role for the airflow, reducing the situation where the patient's inhalation effect is affected by overheating of the airflow. On the other hand, the flow-equalizing fan 223 can also divert the gas so that the gas flows evenly into the inside of the breathing mask 15, thereby improving the comfort of the user;

[0056] When the ventilator body 1 is not in use, the breathing mask 15 is disassembled and the ventilator body 1 is not in use, so that the heated atomizing humidifier body 211 will also stop running, and the thin-walled delivery tube 221 will stop delivering the heated airflow, so that the thin-walled delivery tube 221 will shrink to its original state. At this time, the flow-equalizing fan 223 installed inside the thin-walled delivery tube 221 close to the breathing mask 15 will also stop flipping, and the opening of the thin-walled delivery tube 221 can be auxiliaryly blocked to reduce dust from entering the thin-walled delivery tube 221. Before the ventilator body 1 is used again, the end of the thin-walled delivery tube 221 close to the flow-equalizing fan 223 is disinfected and cleaned.
