Description

Technical Field

[0001] The utility model relates to the technical field of atomization therapy, in particular to a breathing atomizer with a heating and temperature control function. Background Art

[0002] Nebulizer inhalation therapy often uses high-speed airflow to spray liquid droplets of medicine in the form of mist, which is inhaled into the respiratory tract through the mouth or nose, thereby achieving the purpose of treating respiratory tract infections, eliminating inflammation, and thinning sputum to assist in expectoration.

[0003] Ventilators are widely used in respiratory failure, anesthesia respiratory management, respiratory support therapy and emergency resuscitation treatment of patients. They are vital medical devices to reduce postoperative complications and save patients' lives. Ventilators generate pure oxygen through an oxygen generation system and deliver the gas to the patient's respiratory tract through a connecting hose and a breathing mask.

[0004] Most patients who use ventilators for respiratory support therapy have inflammation or sputum in their respiratory tracts. Currently, conventional nebulizer inhalation therapy often requires the breathing mask to be removed before nebulizer inhalation therapy can be performed. Respiratory support therapy and nebulizer inhalation therapy cannot be performed at the same time, which may cause the patient's respiratory tract inflammation or respiratory tract infection to worsen. In addition, patients with respiratory failure who receive respiratory support therapy for a long time generally experience dry respiratory tracts. Increasing the moisture in the ventilator oxygen pipeline is a technical problem that people in this field need to solve.

[0005] The autumn and winter seasons in northern China are relatively cold. When using a ventilator for respiratory support treatment, the oxygen inhaled by the patient is relatively cold, which is not conducive to the patient's rehabilitation treatment. If a ventilator with heating and temperature control function is provided to increase the temperature of the oxygen inhaled by the patient, it will greatly improve the patient's oxygen inhalation comfort and be beneficial to the patient's recovery process.

[0006] At present, most nebulizer therapy masks are equipped with ventilation holes for patients to breathe. Some patients need nebulized drugs for nebulizer inhalation therapy. When patients undergo nebulizer inhalation therapy, the nebulized drugs will be sprayed out during the exhalation process, which reduces the concentration of the drugs and affects the nebulization effect. It is a technical problem that technical personnel in this field need to solve to provide a respiratory nebulizer that reduces drug exhalation, performs respiratory support therapy and nebulizer inhalation therapy at the same time, and has a heating and temperature control function.

Figure 6 A polypropylene hydrophobic membrane material is arranged in the gap of the layer structure, and the surface of the polypropylene hydrophobic membrane material is coated with silver zinc ions, thereby destroying the enzyme structure on the surface of bacteria, thereby achieving the antibacterial purpose.

[0045] The breathing mask 1 is provided with a breathing valve 3, referring to Figure 3 The breathing valve 3 is symmetrically distributed on both sides of the breathing mask 1. The breathing valve 3 is set to be closed during exhalation and opened during inhalation to reduce the exhalation of the atomized medicine and improve the atomization effect of the patient; specifically, the breathing valve 3 includes a valve seat 3-6, referring to Figures 7 to 9 , the valve seat 3-6 has a groove, refer to Fig. 9 A cover 3-1 is buckled on the top of the valve seat 3-6, and the cover 3-1 is buckled in the groove. The cover 3-1 is densely covered with tiny vents, and air enters the valve seat 3-6 along the tiny vents; an exhalation hole 3-4 is opened at the bottom of the valve seat 3-6, refer to Figure 8 A rubber pad 3-5 is arranged in the groove, and the rubber pad 3-5 is laid above the exhalation hole 3-4. The diameter of the rubber pad 3-5 is adapted to the inner contour of the groove. When inhaling, the rubber pad 3-5 blocks the exhalation hole 3-4, and the air enters the breathing mask 1 from the inhalation hole 3-2 arranged above the valve seat 3-6.

[0046] A plurality of inhalation holes 3-2 are evenly distributed on the side wall of the valve seat 3-6 close to the cover body 3-1, and the inhalation holes 3-2 are configured to expand gradually from the inside to the outside. A one-way baffle 3-3 is hinged on the inhalation hole 3-2, and the one-way baffle 3-3 is configured to swing outward during inhalation, and air enters the breathing mask 1 along the inhalation hole 3-2.

[0047] The front end of the breathing mask 1 is attached with a silicone cushion 2, referring to Figure 4 The silicone cushion 2 is adapted to the outer contour of the breathing mask 1; the silicone cushion 2 is provided with a depression adapted to the front end of the breathing mask 1, and the depression fits on the breathing mask 1 to improve the sealing between the breathing mask 1 and the facial contour and the comfort of use.

[0048] The connecting hose 6 is connected to the nebulizer 8 and the ventilator 10 respectively through the three-way pipe 7. The nebulizer 8 and the ventilator 10 are turned on synchronously to perform respiratory support and nebulization inhalation treatment at the same time. Patients undergoing respiratory support treatment can also undergo nebulization inhalation treatment at the same time, which reduces the patient's hospitalization time, reduces the probability of respiratory tract infection, and improves the patient's comfort and nebulization efficiency.

[0049] The atomizer 8 is provided with a liquid storage tank inside. Figure 5 A drug delivery tube 13 is arranged above the liquid storage tank, and the drug delivery tube 13 has a drug delivery hole 9. The drug delivery hole 9 is arranged above the atomizer 8. When the liquid medicine or clean water in the liquid storage tank is insufficient, the drug is added to the liquid storage tank through the drug delivery hole 9. The liquid storage tank is connected to the atomization pipeline, and compressed air flows in the atomization pipeline. The compressed air sucks out the liquid medicine or clean water in the liquid storage tank, and sprays it in the form of mist after atomization through the atomization pipeline, so as to increase the humidity of the oxygen pipeline of the ventilator, moisten the patient's respiratory tract, or directly act on the respiratory tract with drugs for treating respiratory tract infections and anti-inflammatory drugs, which has a better therapeutic effect than swallowing drugs.

[0050] Specifically, a micro air compressor 11 is arranged below the atomization pipeline, and a driver 12 is arranged at one end of the micro air compressor 11. The driver 12 is connected to a crankshaft arranged in the micro air compressor 11, and a piston is arranged on the crankshaft. The piston is placed in the cylinder of the micro air compressor 11. The piston compresses the air in the micro air compressor 11 and discharges the compressed air along the atomization pipeline, thereby generating a negative pressure in a liquid storage tank connected to the atomization pipeline. According to the Venturi effect, the pressure is low where the gas flow rate is large, thereby generating a negative pressure in the liquid storage tank connected to the atomization pipeline, sucking out the medicine liquid or clean water in the liquid storage tank, and colliding with a blocking bar arranged at the front end of the atomization pipeline, so that the medicine liquid or clean water is transformed into mist particles and sprayed out, and flows through the three-way pipe 7 through the connecting hose 6 into the patient's respiratory tract, so as to perform atomization treatment on the patient's respiratory tract or moisten the patient's respiratory tract.

[0051] Preferably, a liquid level sensor is provided in the liquid storage tank, and the liquid level sensor is electrically connected to the control circuit. The liquid level sensor detects the liquid level changes in the liquid storage tank in real time, and transmits the currently detected liquid level value to the control circuit; the control circuit has a set liquid level threshold. When the liquid level sensor detects that the liquid level in the liquid storage tank reaches the set liquid level threshold, the control circuit controls an alarm arranged on the control circuit to sound an alarm to remind medical staff to add liquid medicine or clean water.

[0052] Specifically, the liquid level sensor is made of an isolated diffused silicon sensitive element. It detects the current liquid level value in the liquid storage tank by sensing the pressure of the current liquid, and transmits the currently detected liquid level value to the control circuit. The control circuit has a set liquid level threshold. When the liquid level value detected by the liquid level sensor reaches the set liquid level threshold, the control circuit controls the alarm set on the control circuit to remind medical staff to add liquid medicine or clean water.

[0053] The breathing mask 1 is provided with a temperature and humidity sensor 4, which is electrically connected to the control circuit. The temperature and humidity sensor 4 detects the temperature and humidity in the breathing mask 1 in real time, and transmits the currently detected temperature and humidity to the control circuit.

[0054] Specifically, the temperature and humidity sensor 4 includes a thermistor and a humidistat at the front end. The thermistor has different resistance values ​​according to the current temperature change of the breathing mask 1, and is converted into a current signal or a voltage signal after being processed by circuits such as voltage stabilization filtering, operational amplification, and nonlinear correction of the control circuit; the humidistat has different resistance values ​​according to the current humidity change of the breathing mask, and is converted into a current signal or a voltage signal after being processed by circuits such as voltage stabilization filtering, operational amplification, and nonlinear correction of the control circuit.

[0055] The atomizer 8 also has a heating tube 14, which is arranged above the atomization pipeline. The heating tube 14 is electrically connected to a control circuit, and the control circuit controls the opening or closing of the heating tube 14 according to the temperature data currently detected by the temperature and humidity sensor 4.

[0056] The control circuit is provided with a temperature threshold, and the temperature and humidity sensor 4 transmits the currently detected temperature data and humidity data to the control circuit. When the temperature detected by the temperature and humidity sensor 4 reaches the set temperature threshold, the control circuit controls the heating tube 14 to be closed; when the temperature detected by the temperature and humidity sensor 4 is lower than the set temperature threshold, the control circuit controls the heating tube 14 to be opened; thereby accurately controlling the temperature, preventing the temperature from being too low and the cold air from entering the respiratory tract, preventing the temperature from being too high and scalding the respiratory tract, and improving the patient's comfort.

[0057] Specifically, a heating resistor wire is arranged in the heating tube 14, and atomized medicine or mist water also flows in the heating tube 14. The heating resistor wire heats the atomized medicine or mist water flowing in the heating tube 14. The atomized medicine at a suitable temperature is beneficial to the patient's absorption, thereby improving the therapeutic effect of the atomized medicine. The heating resistor wire is electrically connected to the control circuit. The heating resistor wire turns on the heating resistor wire to start heating or turns off the heating resistor wire to stop heating according to the on-off signal of the control circuit. When the temperature detected by the temperature and humidity sensor 4 reaches the set temperature threshold, the control circuit controls the heating resistor wire arranged in the heating tube to stop heating. When the temperature detected by the temperature and humidity sensor 4 is lower than the set temperature threshold, the control circuit controls the heating resistor wire arranged in the heating tube 14 to start heating.

[0058] Preferably, a humidity threshold is also provided on the control circuit, and the temperature and humidity sensor 4 transmits the currently detected temperature data and humidity data to the control circuit. The control circuit is electrically connected to the driver 12. When the humidity detected by the temperature and humidity sensor 4 reaches the set humidity threshold, the control circuit controls the rotation speed of the driver 12 to decrease, thereby controlling the atomizer to reduce the atomization amount; when the humidity detected by the temperature and humidity sensor 4 is lower than the set humidity threshold, the control circuit controls the rotation speed of the driver 12 to increase, thereby controlling the atomizer to increase the atomization amount.
