Description

Technical Field

[0001] The utility model relates to the technical field of nursing equipment, in particular to an airway humidification device for nursing. Background Art

[0002] During natural breathing, the upper respiratory tract heats and humidifies the inhaled gases. After an artificial airway is established, the upper respiratory tract's heating, humidification, filtering and defense functions are lost, and water loss increases, leading to drying of respiratory secretions and weakened ciliary activity, which can easily lead to serious complications such as airway obstruction, atelectasis or increased infection rate. An artificial airway maintains a patent airway through endotracheal intubation and tracheotomy to save the patient's life. The airway must be fully humidified and kept moist to maintain the normal physiological and defense functions of the airway mucociliary system.

[0003] Since the airway is opened and the respiratory pathway is changed, the airway's own heating and humidification function is significantly reduced, and patients are susceptible to various complications such as lung infection. Therefore, whether the airway is fully humidified is one of the important factors in whether tracheotomy patients will develop lung infection. After the airway is opened, airway management is the focus of clinical nursing work, and humidification is the top priority of airway management. Insufficiently humidified oxygen entering the airway can dry the airway and reduce the purification function. Room temperature humidified oxygen therapy can easily cause respiratory discomfort in patients and affect the effect of oxygen therapy. Utility Model Content

[0023] A heating rod 7 is provided at the bottom of the humidification tank 1, and the heating rod 7 can be electrically heated to preheat the humidification liquid in the humidification tank 1. A liquid suction pipe 4 and an atomizing sheet 5 connected to the liquid suction pipe 4 are provided at the center of the humidification tank 1. The air intake pipe 2 extends into the humidification tank 1 and contacts the atomizing sheet 5. The liquid suction pipe 4 draws the humidification liquid upward to contact the atomizing sheet 5 and converts it into water mist through ultrasonic energy. The heated humidification liquid is atomized and delivered to the patient's airway through the air delivery pipe 2. A wire mesh defoaming plate 6 is provided inside one end of the air intake pipe 2 close to the atomizing sheet 5 to remove entrained mist and ensure the transmission efficiency of the heated mist.

[0024] Combination Figure 2Two hard auxiliary tubes 9 corresponding to the internal connection of the humidifier tank 1 are also provided at the two ends of the top of the humidifier tank 1. The top of the hard auxiliary tube 9 can be sealed to ensure the airtightness of the humidifier tank 1. A float rod 10 is provided in the hard auxiliary tube 9. The hard auxiliary tube 9 can provide guidance for the movement of the float rod 10 to avoid affecting the float rod 10. The top of the float rod 10 is in the hard auxiliary tube 9. The hard auxiliary tube 9 has space for the float rod 10 to move. The bottom of the float rod 10 is on the liquid surface inside the humidifier tank 1. The float rod 10 can be used to sense the change of the liquid level inside the humidifier tank 1. When the liquid level is insufficient, the humidification liquid is filled into the humidifier tank 1 in time through the control system through the liquid inlet tube 8 to keep the water amount in the humidifier tank 1 constant. There is no need to manually open the ventilator pipeline to add liquid to the humidifier tank 1, so as to ensure its airtightness and prevent pollution.

[0025] The humidification tank 1 is also provided with a photoelectric transmitter 11 and a photoelectric receiver 12 on the circumferential side wall. The photoelectric transmitter 11 and the photoelectric receiver 12 can be installed inside the side wall of the humidification tank 1. The tank wall at the signal transmission and receiving path can be made of transparent material to ensure the normal transmission and reception of photoelectric signals. The photoelectric transmitter 11 and the photoelectric receiver 12 are respectively adapted to the two buoy rods 10 in the two hard auxiliary tubes 9.

[0026] The buoy rod 10 floats up and down due to the buoyancy of water as the liquid level in the humidification tank 1 changes. The photoelectric transmitter 11 transmits a signal to detect the specific position of the buoy rod 10. When the liquid level is in a normal horizontal position, the photoelectric receiver 12 can receive the transmitter signal, and the humidification tank 1 is in a normal placement state.

The alarm monitoring the humidification tank 1 can send an alarm signal to remind the staff to straighten the humidification tank 1 in time to avoid liquid backflow.

[0027] Example 2

[0028] This embodiment is a nursing airway humidification device, such as Figure 1 As shown, it includes a humidification tank 1 and an inhalation pipe 2 connected to the humidification tank 1, the end of the inhalation pipe 2 away from the humidification tank 1 is connected to an extension pipe 3 corresponding to the airway, a heating rod 7 is provided at the bottom of the humidification tank 1, a liquid suction pipe 4 and an atomization sheet 5 connected to the liquid suction pipe 4 are provided at the center of the interior of the humidification tank 1, and the inhalation pipe 2 extends into the humidification tank 1 and is connected to the atomization sheet 5.

[0029] The end of the air intake pipe 2 close to the extension pipe 3 is connected to an auxiliary heating component, which is sleeved on the outer periphery of the air intake pipe 2 and is used for secondary heating of the air intake pipe 2 that transmits the mixed gas of oxygen and heated humid gas to reduce the generation of condensed water. Specifically, Figure 3The auxiliary heating component includes a positioning seat 13 and a heating tube 14 arranged on one side of the bottom of the positioning seat 13. A heating wire 15 is arranged on the inner wall of the heating tube 14. The free end of the intake pipe 2 passes through the interior of the heating tube 14 and the end of the intake pipe 2 extending out of the heating tube 14 is sealed and connected to the extension pipe 3. The positioning seat 13 can fix the entire auxiliary heating component at a certain position of the bed, strengthen the positioning of the pipeline, and avoid the pipeline from being pulled. The auxiliary heating component can be sleeved on the outer periphery of the intake pipe 2 and the outer periphery of the patient's exhalation pipe, so as to minimize the generation of condensed water.

[0030] The heating wire 15 outside the inhalation tube 2 can make the gas in the tube be heated evenly, thereby minimizing the generation of condensed water. The temperature control monitoring and control devices such as temperature sensors in the prior art can be added to the humidification tank 1 and the auxiliary heating component to keep the temperature of the heated gas controllable. The temperature of the output gas after heating and atomization by the humidification tank 1 can be controlled to be 37°C and the absolute humidity is 42-44mg / L. When passing through the auxiliary heating component on the periphery of the inhalation tube 2, the temperature is controlled to rise by 3°C under the action of the heating wire 15. When the gas passes through the extension tube 3 without the heating wire, the temperature is reduced by 3°C, and the temperature of the gas finally delivered to the endotracheal intubation and tracheotomy catheter is restored to 37°C, the absolute humidity is 42-44mg / L, and the relative humidity is 95-100%. The humidification tank 1 and the auxiliary heating component allow the patient to continuously humidify the respiratory tract at a constant temperature while inhaling oxygen, thereby ensuring the physiological function of the airway, improving the satisfaction with airway humidification, and significantly reducing the occurrence of lung infection, thereby reducing the workload of nurses and improving the effect of oxygen therapy.

[0031] The airway humidification device of the utility model can be used in conjunction with a Venturi oxygen flow regulator to achieve high-flow warm and humidified oxygen therapy, can provide lasting and correct oxygen concentration, and can control the temperature and humidity of the inhaled gas, maintain the optimal temperature and relative humidity required for the airway, prevent airway drying, improve the patient's comfort and lung compliance, maintain the mucociliary protective function, and clear retained secretions.
