Description

Technical Field

[0001] The invention relates to the technical field of medical equipment, and in particular to a portable tracheal humidifier. Background Art

[0002] For patients with tracheotomy, their upper respiratory tract loses its function of humidifying gas, which can easily cause sputum crust to form on the artificial airway and upper respiratory tract, thereby blocking the bronchi and causing breathing difficulties. Therefore, the airway needs to be humidified.

[0003] At present, the airway humidification methods mainly include intermittent push humidification method, continuous drip method through infusion tube, nebulization humidification, etc.; the intermittent push humidification method is to manually use a syringe to push the humidification liquid into the artificial trachea. The operation is simple and convenient, but it cannot be continuous. The amount of humidification liquid injected into the tracheal tube each time is large, the speed is difficult to control, and it has a certain irritation to the patient; the continuous drip method through infusion tube is to connect the trachea through an infusion bottle, which meets the requirements of continuous humidification of the human airway, but this method needs to be completed under the operation of medical staff, and the infusion bottle is not convenient to carry and move, and the patient's activities are restricted. Artificial nebulization humidification uses a nebulizer to atomize the humidification liquid and then send it into the trachea. Its airway humidification effect is better, but it is carried out by a nebulizer machine and is limited by the site; and the above method cannot heat the humidification liquid. When the liquid temperature is low, it is easy to cause respiratory discomfort to the patient. Summary of the invention

[0004] In order to overcome the deficiencies of the prior art, the object of the present invention is to provide a portable tracheal humidifier which is easy to carry and use and has a good humidification effect.

[0005] The technical solution adopted by the present invention is as follows: A portable tracheal humidifier comprises an outer shell and a battery assembly, and also comprises an infusion pump, an infusion tube, a liquid storage box, a heating assembly and an atomization assembly; The infusion pump and the battery assembly are integrated in the outer shell, and the liquid storage box is detachably mounted on the outer shell; The infusion pump extracts humidification liquid from the liquid storage box through the infusion tube, and the humidification liquid in the infusion tube passes through the heating component and the atomizing component to form a humid hot air flow, and the humid hot air flow enters the trachea through the infusion tube; The battery assembly supplies power to the infusion pump, the heating assembly, and the atomization assembly.

[0006] Compared with the prior art, the present invention has the following beneficial effects: 1. The humidifier is powered by a battery assembly, which does not need to be plugged in, and the infusion pump is integrated in the shell, which is convenient to carry; 2. By setting up a detachable liquid storage box, the humidifying liquid can be replenished at any time; 3. Through the infusion pump, it can ensure that the spray can be carried out continuously and accurately give the patient the required humidity; 4. The heating component can ensure that the moist and hot air flow is heated to a temperature suitable for the human body, avoiding discomfort to the patient caused by the cold air generated by atomization.

[0007] As a preferred embodiment of the present invention, it also includes an alarm. A water level monitoring sensor is arranged in the liquid storage box to monitor the water level in the liquid storage box. A temperature sensor is arranged at one end of the infusion tube close to the atomization component to monitor the temperature of the humid hot air flow. When the water level is lower than the preset water level, the temperature of the humid hot air flow exceeds the preset temperature, and the power of the battery component is lower than the preset power, the alarm sends out different alarms.

[0008] Beneficial effects: Abnormal working conditions of the humidifier include overheat protection, low water level, and insufficient battery power. This solution sets sensors and alarms to issue alarm prompts in time to ensure the safety of patients during use.

[0009] As a preferred embodiment of the present invention, it also includes an LED display screen, and the alarm flashes images of different colors on the LED display screen according to different alarms. The alarm includes a buzzer, and when the flashing image appears, the buzzer starts; when the water level is lower than the preset water level, the battery assembly stops supplying power to the infusion pump, and when the temperature of the humid hot air flow exceeds the preset temperature, the battery assembly stops supplying power to the heating assembly.

[0010] Beneficial effects: The LED display screen can monitor various information of the humidifier in real time, and can promptly remind of abnormalities through the buzzer, and can also display different abnormal states, making it convenient to handle abnormalities; and in the event of overheating.

[0011] As a preferred embodiment of the present invention, the heating component uses a heating wire, which is installed in the infusion tube and located between the infusion pump and the atomization component.

[0012] Beneficial effect: The heating wire is inside the infusion tube, which ensures that the humidification liquid is in a humidified state for a long distance inside the infusion tube. As a preferred embodiment of the present invention, a shoulder strap is fixedly connected to the outer shell.

[0013] Beneficial effect: By providing a shoulder strap, the humidifier can be carried by hand or hung on the shoulders of the body, making it convenient for the patient to get up and move around.

[0014] As a preferred embodiment of the present invention, it also includes a filter assembly, which includes a liquid filter screen and a gas filter screen arranged in the infusion tube, the liquid filter screen is used to filter the humidification liquid, and the gas filter screen is used to filter the air.

[0015] Beneficial effect: By setting up multiple layers of filtration, the cleanliness of the gas input into the trachea is ensured, providing safe breathing protection.

[0016] As a preferred embodiment of the present invention, there are two liquid storage boxes, and the infusion tubes can extract the humidifying liquid in the corresponding liquid storage boxes separately.

[0017] Beneficial effect: After a single liquid storage box is used, the humidifier needs to be stopped and new humidifying liquid needs to be injected. However, by setting up two liquid storage boxes, they can be used alternately. After one of them is used up, it can be replaced in time, so that the humidifier can continuously provide water vapor.

[0018] As a preferred embodiment of the present invention, a first channel is transversely provided in the outer shell, the infusion tube is connected to the first channel, two second channels are vertically provided at intervals at the bottom of the first channel, and both of the two liquid storage boxes are equipped with a connecting tube, the upper end of the connecting tube can be inserted into the second channel, and the lower end of the connecting tube is located inside the outer shell; It also includes a first control valve, two second control valves, and two third control valves. The first control valve is arranged in the first channel and located between the two second channels. The first control valve can control the opening and closing of the first channel; the two third control valves are respectively arranged in the corresponding second channels and are used to open and close the corresponding second channels; the two connecting pipes are provided with liquid inlet holes in the corresponding liquid storage boxes, and the two third control valves are used to open and close the corresponding liquid inlet holes.

[0019] Beneficial effects: The first channel, two second channels, and two connecting tubes are separated by the first control valve in the middle position, so that the infusion pump can extract the humidifying liquid in each liquid storage box separately and block another channel when extracting, so as to facilitate the disassembly of the liquid storage box for water addition.

[0020] As a preferred embodiment of the present invention, along the flow direction of the humidifying liquid in the first channel, the two liquid storage boxes are a spare box body and a first box body; The first control valve is a negative pressure valve, and the third control valve is a floating ring. The floating ring floats with the liquid level in the liquid storage box and is vertically slidably installed on the connecting pipe. When a certain amount of humidifying liquid in the first box body is consumed, the floating ring can block the connecting pipe. The continuous operation of the infusion pump will cause the air pressure on the side of the first channel close to the infusion tube to decrease, thereby opening the negative pressure valve, and the two sides of the first channel are connected, so that the infusion pump can extract the humidifying liquid in the spare box body; The second control valve includes a tension spring and a second sleeve. A connecting hole is provided on the side of the second sleeve. When the connecting pipe is inserted into the second channel, the connecting pipe is connected with the bottom of the second sleeve, and the second sleeve is pushed into the first channel. The first channel is connected with the connecting pipe through the connecting hole. When the first box body is taken out, the corresponding connecting pipe is separated from the second channel, and the tension spring drives the second sleeve to contract and block the second channel.

[0021] Beneficial effect: Through the above structure, after the humidifying liquid in the first box body is used up, the connecting pipe corresponding to the first box body can be automatically closed, and the negative pressure valve can be opened, so that the infusion pump can automatically extract the humidifying liquid in the spare box body. When the user removes the first box body, the corresponding second channel can be automatically closed to ensure that the first channel is in a negative pressure state. By replacing the electric control valve with a pure mechanical valve body, equipment and usage costs can be saved.

[0022] As a preferred embodiment of the present invention, it comprises a wrapping bag, which is detachably mounted on the outer shell and wraps the two liquid storage boxes.

[0023] Beneficial effect: By providing a wrapping bag, the liquid storage box can be reinforced to prevent the connecting pipe from being separated from the second channel. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] Embodiment 1: See also Figure 1 As shown, the portable tracheal humidifier of this embodiment includes an outer shell 1, in which a battery assembly and an infusion pump 2 are integrated. A liquid storage box with a capacity of 100-150 ml is clamped at the bottom of the outer shell 1. The liquid storage box is filled with humidifying liquid, and the humidifying liquid can be physiological saline, distilled water or sterile water.

[0029] The infusion pump 2 adopts a peristaltic pump, which squeezes the part of the infusion tube 21 inside the outer shell 1. One end of the infusion tube 21 penetrates into the liquid storage box, and the other end of the infusion tube 21 is connected to a heating component and an atomization component in sequence, and is connected to an artificial trachea through the end.

[0030] Among them, the heating component adopts a heating wire, and the atomization component adopts an ultrasonic atomization sheet.

When the power of the battery component is low, it will be displayed on the LED screen 11 and an alarm will be sounded. When the water level monitored by the water level sensor is lower than the preset water level, the infusion pump 2 stops, and when the temperature monitored by the temperature sensor is higher than the preset temperature, the heating component stops, and different patterns will be displayed on the LED screen 11, and the alarm will send a sound reminder through the buzzer.

[0032] Among them, the LED screen 11 can display the extraction speed of the infusion pump 2 and the humidification liquid temperature. The outer shell 1 is also provided with a control button, through which the user can conveniently adjust the extraction speed of the infusion pump 2 and the heating temperature of the heating component.

[0033] Wherein, a shoulder strap 12 is fixedly connected to the outer shell 1 to facilitate the user to carry it.

[0034] Among them, it also includes a filter component, which includes a liquid filter screen and a gas filter screen arranged in the infusion tube 21. The liquid filter screen is used to filter the humidification liquid, and the gas filter screen is used to filter the air.

[0035] The portable tracheal humidifier of this embodiment is easy to carry and can be used by the user when getting out of bed. The liquid storage box can be easily replaced, and the trachea can be humidified for a long time. The heating component and the atomization component enable the humidifier to have temperature control and atomization functions, making the entire humidification process more comfortable. The LED display 11 can display the operating status of the humidifier. Combined with the alarm, it can promptly remind the user to deal with abnormalities, thereby ensuring safe use.

[0036] Embodiment 2: See also Figures 2 to 6 As shown, on the basis of the first embodiment, the portable tracheal humidifier of this embodiment has two liquid storage boxes. Along the flow direction of the humidifying liquid in the first channel 13, the two liquid storage boxes are respectively a spare box body 32 and a first box body 31. A connecting pipe 33 is provided in each of the two liquid storage boxes. The lower end of the connecting pipe 33 is against the inner bottom wall of the liquid storage box, and the side wall of the connecting pipe 33 is provided with a liquid inlet hole 34. A waterproof breathable valve 35 is provided on the upper part of the liquid storage box, which can ensure that the air pressure inside and outside the box is balanced during the extraction of the humidifying liquid.

[0037] Among them, see Figure 3 and Figure 4 As shown, a first channel 13 is transversely disposed in the outer shell 1 , the infusion tube 21 is connected to the first channel 13 , two second channels 14 are vertically spaced apart at the bottom of the first channel 13 , and the upper end of the connecting tube 33 can be inserted into the second channel 14 .

[0038] The portable tracheal humidifier also includes a first control valve, two second control valves, and two third control valves; See also Figure 4 and Figure 6 As shown, the first control valve is a negative pressure valve, which includes a first plate body 41 and a first sleeve body 42. The first plate body 41 is located in the middle of the first channel 13, and a sliding hole is transversely opened on the first plate body 41. The first sleeve body 42 can slide in the sliding hole. An extension plate is provided on the outer periphery of the first sleeve body 42, and a compression spring 43 is provided between the extension plate and the first plate body 41. A through hole is provided on the side of the first sleeve body 42. When the through hole is located on the left side of the first channel 13, the first channel 13 is connected as a whole. When the through hole is located on the right side, the middle of the first channel 13 is blocked. When a certain negative pressure is reached on the left side of the first channel 13, the first sleeve body 42 can slide to the left. The second control valve comprises a tension spring 51 and a second sleeve 52. A connecting hole is provided on the side of the second sleeve 52. A clamping ring 331 is provided on the upper end of the connecting pipe 33. When the connecting pipe 33 is inserted into the second channel 14, the clamping ring 331 holds the second sleeve 52 in place. A rubber ring 53 is provided inside the second sleeve 52 to clamp the top end of the connecting pipe 33 and ensure sealing. The third control valve is a floating ring 6 , which floats along with the liquid level in the liquid storage box and is vertically slidably mounted on the connecting pipe 33 . When a certain amount of humidifying liquid in the first box body 31 is consumed, the floating ring 6 can block the connecting pipe 33 .

[0039] Among them, see Figure 2 As shown, it also includes a wrapping bag 7, which is detachably mounted on the outer shell 1 and wraps the two liquid storage boxes to prevent the liquid storage boxes from accidentally falling out.

[0040] The usage and principle of this embodiment are as follows: The infusion pump 2 first extracts the humidifying liquid in the first box body 31. When a certain amount of the humidifying liquid is consumed, the floating ring 6 moves down to block the liquid inlet hole 34 on the connecting tube 33. The continuous operation of the infusion pump 2 causes the air pressure on the left side of the first channel 13 close to the infusion tube 21 to decrease, so that the first sleeve 42 moves leftward until the first control valve is opened, so that the left side of the first channel 13 is connected to the right side of the box, and the two sides of the first channel 13 are connected, so that the infusion pump 2 can extract the humidifying liquid in the standby box body 32; When new humidification liquid is needed, the used first box body 31 is removed, and when the connecting tube 33 is separated from the second sleeve body 52, the tension spring 51 automatically retracts, so that the second sleeve body 52 blocks the corresponding second channel 14. Although the air pressure in the first channel 13 may be temporarily restored when it is separated, the continuous operation of the infusion pump 2 will form a negative pressure in the first channel 13 again. Therefore, the spare box body 32 can continue to work, and after the first box body 31 is filled with humidification liquid, it can be reinserted into the corresponding second channel 14; When the first box body 31 is reinserted, the air pressure in the first channel 13 is restored, and the first control valve closes the middle of the first channel 13, so that the infusion pump 2 re-extracts the humidifying liquid in the first box body 31. At this time, the spare box body 32 can also be replaced.

[0041] Therefore, the two liquid storage boxes in this embodiment allow the humidifier to automatically switch the liquid storage box to be extracted when in use, and can ensure the continuous flow of humidifying liquid as much as possible, without having to stop humidification for a long time due to adding water to the liquid storage box.

[0042] The above-mentioned embodiments are only preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
