Description

Technical Field

[0001] The utility model relates to the technical field of ventilators, in particular to a respiratory humidifier and a ventilator. Background Art

[0002] In modern clinical medicine, ventilators, as an effective means of artificially replacing spontaneous ventilation functions, have been widely used in respiratory failure caused by various reasons, anesthesia respiratory management during major surgery, respiratory support therapy and emergency resuscitation. When a ventilator is used alone to treat respiratory diseases, the ventilator outputs dry gas, and patients are prone to side effects such as dry nose and throat, tongue pain, and even nose bleeding. Therefore, ventilators are generally equipped with respiratory humidifiers to increase the humidity of the gas entering the lungs.

[0003] When the humidity adjusted by the humidifier is too high, water is likely to accumulate inside the ventilator pipes and the mask. This is mainly due to condensation when the humidified air contacts the cooling tube and the mask. The accumulated water may not only produce noise and affect the patient's sleep quality, but may also cause water droplets to fall on the patient's face, causing discomfort to the patient. In addition, excessive humidity will cause the humidity in the mask pipes to be too high, giving the patient a stuffy feeling in the summer. If the humidifier is accidentally tilted, the water inside the humidifier will easily flow back into the inlet and outlet trachea, and then enter the equipment along the pipe, which can easily affect the service life of the ventilator. When using the ventilator, it is generally necessary to filter the incoming air first, but the filtration is generally only filtered through one layer of filtration structure, and the filtration time is short, and the filtration effect is poor, which can easily lead to the purity of the air inhaled by the patient when the ventilator is used. Utility Model Content

[0004] The purpose of the present utility model is to provide a respiratory humidifier and a ventilator to solve the problems raised in the above-mentioned background technology that water is easily accumulated in the ventilator pipes and the inside of the mask when the ventilator is used, which easily affects the patient's comfort and service life, and the purity of the air inhaled by the patient is low.

[0005] To achieve the above-mentioned objectives, the utility model provides the following technical solutions: a respiratory humidifier and a respirator, comprising a humidifying outer box, a control panel being installed on the surface of the humidifying outer box, a water tank being fixed inside the humidifying outer box, an air outlet pipe being fixed on the surface at the top position of the water tank, an air inlet pipe being arranged on one side of the air outlet pipe, and the air inlet pipe being fixed on the surface of the water tank, a mask being arranged on one side of the humidifying outer box, an electric heating wire being installed on the inner wall at the bottom position of the humidifying outer box, an input end of the electric heating wire being electrically connected to an output end of the control panel, a temperature monitor being installed on the inner wall of the humidifying outer box, an input end of the temperature monitor being electrically connected to an output end of the control panel, an anti-condensation mechanism being arranged on one side of the humidifying outer box, the anti-condensation mechanism being composed of a moisture absorbing component, a breathing hose and a water collecting box, one end of each of the air outlet pipe and the air inlet pipe being provided with an anti-backflow mechanism, and the interior of the anti-backflow mechanism comprises an anti-backflow component and an air guide pipe.

[0006] Preferably, a water collecting box is fixed at the bottom of the humidification outer box, a drainage pipe is installed on the surface of the water collecting box, the water collecting box is connected to the air outlet pipe, a breathing hose is fixed at the top of the water collecting box, one end of the breathing hose is connected to the mask, and a moisture absorbing component is provided inside the mask.

[0007] Preferably, the interior of the hygroscopic component includes a sticky patch, hygroscopic silica gel and sticky glue, the hygroscopic silica gel is placed inside the mask, the edge of the hygroscopic silica gel is sticky glue, the edge of the inner wall of the mask is sticky patch, and the sticky patch and sticky glue are bonded together.

[0008] Preferably, air guide tubes are fixed on both sides of the center position of the water tank, the structure of the air guide tubes is an L-shaped structure, and an anti-backflow component is provided on the surface of the air guide tubes.

[0009] Preferably, the interior of the anti-backflow component includes a gravity ball, a drainage hole and a connecting hose. The bottom of the air duct is provided with a drainage hole. A connecting hose is fixed at the top of the air duct. One end of the connecting hose is respectively connected to the air outlet pipe and the air inlet pipe. The surface of the connecting hose is provided with a gravity ball, and the gravity ball and the connecting hose slide together.

[0010] A ventilator comprises a casing, the surface of the casing is covered with a cover plate, the cover plate is detachably connected to the casing by screws, a partition plate is fixed inside the casing, a blower is installed on the surface of the partition plate, the input end of the blower is electrically connected to the output end of a control panel, one end of the blower passes through the partition plate and extends to one side of the partition plate, the other end of the blower is connected to an air inlet pipe through a pipe, a high-efficiency filtering mechanism is provided on the surface of the casing, and the interior of the high-efficiency filtering mechanism includes a filter assembly and a baffle.

[0011] Preferably, a baffle is fixed inside the casing, the baffle is located below the blower, and a filter assembly is provided on one side of the baffle.

[0012] Preferably, the filter assembly consists of an air intake cover, a filter screen and an activated carbon adsorption layer. The activated carbon adsorption layer is placed inside the casing, and the surface of the activated carbon adsorption layer is tightly fitted with the surfaces of the casing, cover plate and baffle respectively.

[0013] Preferably, an air intake hood is fixed on one side of the bottom position of the casing, the air intake hood is connected to the casing, the air intake hood is located on one side of the baffle, a filter is inlaid on one side of the air intake hood, and the structure of the filter is an inclined structure.

[0014] Compared with the prior art, the beneficial effects of the present invention are: the respiratory humidifier and the ventilator not only improve the comfort level of the patient when the ventilator is used, are not easily affected by water backflow and the service life, but also improve the purity of the air inhaled by the patient when the ventilator is used;

[0015] By providing an anti-condensation mechanism, when the mask is put on the patient's face during use, condensation will easily occur when the humidified air contacts the exhaust pipe, breathing hose and mask, resulting in water accumulation. Since the water collecting box is located at the bottom of the humidification outer box, the condensed water generated by the exhaust pipe and breathing hose can flow to the inside of the water collecting box under the action of gravity. At the same time, the hygroscopic silica gel sticks to the inside of the mask and absorbs the condensed water inside the mask and part of the moisture in the air under the action of the hygroscopic silica gel to avoid excessive humidity. At the same time, the condensed water can be prevented from dripping onto the patient's face. After a period of time, the hygroscopic silica gel can be torn off with the help of the adhesive tape and replaced with a new one to achieve the moisture absorption and anti-condensation function of the ventilator, thereby improving the comfort of the patient when using the ventilator.

[0016] By providing an anti-backflow mechanism, when in use, the air outlet pipe and the air inlet pipe are guided by the anti-backflow mechanism. If the ventilator is accidentally tilted, since the air guide pipe is located on both sides of the center position of the water tank, and the water level after tilting is generally the middle of the water tank lower than the edge, the water inflow of the air guide pipe is relatively small. Since the air guide pipe is an L-shaped structure, water is retained inside the air guide pipe. After the ventilator is straightened, the water remaining in the air guide pipe will be discharged along the drain hole under the action of gravity. If a large amount of water enters the air guide pipe and flows into the inside of the connecting hose, the gravity ball will move synchronously after the ventilator is tilted, driving the end of the connecting hose connected to the air outlet pipe and the air inlet pipe close to the inner wall, thereby preventing water accidentally flowing into the connecting hose from entering the air outlet pipe and the air inlet pipe, thereby realizing the anti-backflow function of the respiratory humidifier, and making it less likely that the service life of the ventilator will be affected by water backflow when in use;

[0017] By providing a high-efficiency filtering mechanism, the air intake hood is placed inside the casing so that the air intake hood is located between the casing and the baffle, and then the cover is covered to the surface of the casing and fixed to the casing by screws. Then the control panel is operated to control the blower to work. Under the action of the blower, air can be evacuated from the inside of the casing, so that the external air passes through the filter and enters the air intake hood. Since the air intake hood is located on one side of the baffle, the air is blocked so that the air enters above the activated carbon adsorption layer and then enters the inside of the blower, which prolongs the reaction time between the air and the activated carbon adsorption layer and filters the air efficiently. At the same time, since the filter is an inclined structure, it is convenient to clean the dust attached to the surface of the filter, so as to realize the high-efficiency filtering function of the ventilator on the incoming air, thereby improving the purity of the air inhaled by the patient when the ventilator is in use.

An air inlet pipe 103 is provided on one side of 102, and the air inlet pipe 103 is fixed on the surface of the water tank 101. A mask 105 is provided on one side of the humidification outer box 1, and a heating wire 106 is installed on the inner wall at the bottom position of the humidification outer box 1. The model of the heating wire 106 can be selected from the CY series. The input end of the heating wire 106 is electrically connected to the output end of the control panel 104. A temperature monitor 107 is installed on the inner wall of the humidification outer box 1. The model of the temperature monitor 107 can be selected from the SDN series. The input end of the temperature monitor 107 is electrically connected to the output end of the control panel 104.

[0025] During use, air enters the interior of the water tank 101 through the air inlet pipe 103. At this time, the control panel 104 is operated to control the heating wire 106 and the temperature monitor 107 to operate. Under the action of the heating wire 106, the water source inside the water tank 101 is heated, so that the gas inside the water tank 101 is heated and humidified, and discharged through the air outlet pipe 102. The temperature is monitored under the action of the temperature monitor 107 to realize the humidification function of the ventilator.

[0026] Furthermore, if Figure 4As shown, an anti-condensation mechanism 4 is provided on one side of the humidification outer box 1. The anti-condensation mechanism 4 consists of a moisture absorbing member 401, a breathing hose 402 and a water collecting box 403. The water collecting box 403 is fixed at the bottom of the humidification outer box 1. A drainage pipe is installed on the surface of the water collecting box 403. The water collecting box 403 is connected to the air outlet pipe 102. A breathing hose 402 is fixed at the top of the water collecting box 403. One end of the breathing hose 402 is connected to the mask 105. Generally, the mask 105 is provided with a hygroscopic component 401 inside, and the interior of the hygroscopic component 401 includes an adhesive patch 4011, hygroscopic silica gel 4012 and an adhesive glue 4013. The hygroscopic silica gel 4012 is placed inside the mask 105, and the adhesive glue 4013 is adhered to the edge of the hygroscopic silica gel 4012. The edge of the inner wall of the mask 105 is adhered with an adhesive patch 4011, and the adhesive patch 4011 and the adhesive glue 4013 are bonded to each other.

[0027] During use, the mask 105 is placed on the patient's face. At this time, since the humidified air is prone to condensation when it contacts the exhaust pipe 102, the breathing hose 402 and the mask 105, water accumulation is generated. Since the water collecting box 403 is located at the bottom of the humidification outer box 1, the condensed water generated by the exhaust pipe 102 and the breathing hose 402 can flow to the inside of the water collecting box 403 under the action of gravity. At the same time, at this time, the hygroscopic silica gel 4012 is adhered to the inside of the mask 105. Under the action of the hygroscopic silica gel 4012, the condensed water inside the mask 105 and some moisture in the air can be absorbed to avoid excessive humidity. At the same time, the condensed water can be prevented from dripping onto the patient's face. After a period of time, the hygroscopic silica gel 4012 can be torn off and replaced under the adhesion of the adhesive 4011 and the adhesive 4013 to realize the moisture absorption and anti-condensation function of the ventilator.

[0028] Furthermore, if Figure 3 As shown, one end of the air outlet pipe 102 and the air inlet pipe 103 are both provided with an anti-backflow mechanism 5, the interior of the anti-backflow mechanism 5 includes an anti-backflow component 501 and an air guide pipe 502, and air guide pipes 502 are fixed on both sides of the center position of the water tank 101. The structure of the air guide pipe 502 is an L-shaped structure, and the surface of the air guide pipe 502 is provided with an anti-backflow component 501, and the interior of the anti-backflow component 501 includes a gravity ball 5011, a drainage hole 5012 and a connecting hose 5013. The bottom of the air guide pipe 502 is provided with a drainage hole 5012, and a connecting hose 5013 is fixed at the top position of the air guide pipe 502. One end of the connecting hose 5013 is respectively connected to the air outlet pipe 102 and the air inlet pipe 103, and the surface of the connecting hose 5013 is provided with a gravity ball 5011, and the gravity ball 5011 and the connecting hose 5013 slide with each other.

[0029] When in use, the air outlet pipe 102 and the air inlet pipe 103 are guided by the anti-backflow mechanism 5. If the ventilator is accidentally tilted, since the air guide pipe 502 is located on both sides of the center position of the water tank 101, and the water level after tilting is generally lower than the edge of the water tank 101 in the middle, the water inflow of the air guide pipe 502 is relatively small. Since the air guide pipe 502 is an L-shaped structure, water is retained inside the air guide pipe 502. After the ventilator is straightened, the remaining water in the air guide pipe 502 will be discharged along the drainage hole 5012 under the action of gravity. If a large amount of water enters the air guide pipe 502 and flows into the connecting hose 5013, the gravity ball 5011 will move synchronously after the ventilator is tilted, driving the end of the connecting hose 5013 connected to the air outlet pipe 102 and the air inlet pipe 103 close to the inner wall, thereby preventing the water accidentally flowing into the connecting hose 5013 from entering the air outlet pipe 102 and the air inlet pipe 103, thereby realizing the anti-backflow function of the respiratory humidifier.

[0030] The utility model also provides a structure of a ventilator as follows Figure 2 As shown, it includes a casing 2, the surface of the casing 2 is covered with a cover plate 201, the cover plate 201 is detachably connected to the casing 2 by screws, a partition plate 202 is fixed inside the casing 2, a blower 203 is installed on the surface of the partition plate 202, and the model of the blower 203 can be selected from the VFC series. The input end of the blower 203 is electrically connected to the output end of the control panel 104, one end of the blower 203 passes through the partition plate 202 and extends to one side of the partition plate 202, and the other end of the blower 203 is connected to the air inlet pipe 103 through a pipe.

[0031] Furthermore, if Figure 2 As shown, a high-efficiency filtering mechanism 3 is provided on the surface of the casing 2, and the interior of the high-efficiency filtering mechanism 3 includes a filter component 301 and a baffle 302. The interior of the casing 2 is fixed with a baffle 302, and the baffle 302 is located below the blower 203. A filter component 301 is provided on one side of the baffle 302, and the filter component 301 consists of an air intake hood 3011, a filter screen 3012 and an activated carbon adsorption layer 3013. An activated carbon adsorption layer 3013 is placed inside the casing 2, and the surfaces of the activated carbon adsorption layer 3013 are tightly fitted with the surfaces of the casing 2, the cover 201 and the baffle 302 respectively. An air intake hood 3011 is fixed on one side of the bottom position of the casing 2, and the air intake hood 3011 is connected to the casing 2. The air intake hood 3011 is located on one side of the baffle 302, and a filter screen 3012 is inlaid on one side of the air intake hood 3011. The structure of the filter screen 3012 is an inclined structure.

[0032] When in use, the air intake hood 3011 is placed inside the casing 2 so that the air intake hood 3011 is located between the casing 2 and the baffle 302. Then, the cover 201 is covered to the surface of the casing 2 and fixed to the casing 2 by screws. Then, the control panel 104 is operated to control the blower 203 to work. Under the action of the blower 203, the inside of the casing 2 can be evacuated, so that the external air passes through the filter 3012 and enters the inside of the air intake hood 3011. Since the air intake hood 3011 is located on one side of the baffle 302, the air is blocked, so that the air enters the activated carbon adsorption layer 3013 and then enters the inside of the blower 203, thereby extending the reaction time between the air and the activated carbon adsorption layer 3013 and efficiently filtering the air. At the same time, since the filter 3012 is an inclined structure, it is convenient to clean the dust attached to the surface of the filter 3012, so as to realize the high-efficiency filtering function of the ventilator for the incoming air.

[0033] Working principle: When in use, first place the air intake cover 3011 inside the casing 2, so that the air intake cover 3011 is located between the casing 2 and the baffle 302, then cover the cover 201 to the surface of the casing 2 and fix the cover 201 to the casing 2 with screws, then operate the control panel 104 to control the blower 203 to work. Under the action of the blower 203, the inside of the casing 2 can be evacuated, so that the external air passes through the filter 3012 and enters the air intake cover 3011 Since the air inlet hood 3011 is located on one side of the baffle 302, the air is blocked, so that the air enters the activated carbon adsorption layer 3013 and then enters the inside of the blower 203, thereby extending the reaction time between the air and the activated carbon adsorption layer 3013 and efficiently filtering the air. At the same time, since the filter 3012 is an inclined structure, it is convenient to clean the dust attached to the surface of the filter 3012, so as to realize the ventilator's efficient filtering function for the incoming air, thereby improving the purity of the air inhaled by the patient when the ventilator is in use.

[0034] Then the air enters the interior of the water tank 101 through the air inlet pipe 103. At this time, the control panel 104 is operated to control the heating wire 106 and the temperature monitor 107 to operate. Under the action of the heating wire 106, the water source inside the water tank 101 is heated, so that the gas inside the water tank 101 is heated and humidified, and discharged through the air outlet pipe 102. The temperature is monitored under the action of the temperature monitor 107 to realize the humidification function of the ventilator.

[0035] When in use, the mask 105 is covered on the patient's face. At this time, since the humidified air is prone to condensation when it contacts the exhaust pipe 102, the breathing hose 402 and the mask 105, water accumulation is generated. Since the water collecting box 403 is located at the bottom of the humidification outer box 1, the condensed water generated by the exhaust pipe 102 and the breathing hose 402 can flow to the inside of the water collecting box 403 under the action of gravity. At the same time, at this time, the hygroscopic silica gel 4012 sticks to the inside of the mask 105. Under the action of the hygroscopic silica gel 4012, the condensed water inside the mask 105 and some moisture in the air can be absorbed to avoid excessive humidity. At the same time, the condensed water can be prevented from dripping onto the patient's face. After a period of time, the hygroscopic silica gel 4012 can be torn off under the adhesion of the adhesive 4011 and the adhesive 4013, and the hygroscopic silica gel 4012 can be replaced to realize the moisture absorption and anti-condensation function of the ventilator, thereby improving the patient's comfort when using the ventilator.

[0036] During use, the air outlet pipe 102 and the air inlet pipe 103 are used to guide air through the anti-backflow mechanism 5. If the ventilator is accidentally tilted, since the air guide pipe 502 is located on both sides of the center of the water tank 101, and the water level after tilting is generally lower in the middle of the water tank 101 than at the sides, the amount of water entering the air guide pipe 502 is relatively small. Since the air guide pipe 502 is an L-shaped structure, water is retained inside the air guide pipe 502. After the ventilator is straightened, the remaining water inside the air guide pipe 502 will be discharged along the drain hole 5012 under the action of gravity. When a large amount of water enters the air duct 502 and flows into the connecting hose 5013, the gravity ball 5011 will move synchronously after the ventilator is tilted, driving the end of the connecting hose 5013 connected to the air outlet pipe 102 and the air inlet pipe 103 to approach the inner wall, thereby preventing the water that accidentally flows into the connecting hose 5013 from entering the air outlet pipe 102 and the air inlet pipe 103, so as to realize the anti-backflow function of the respiratory humidifier, so that the service life of the ventilator is not easily affected by water backflow during use, and finally the use of the ventilator is completed.

[0037] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
