The invention relates to the technical field of medical supplies, in particular to a novel multifunctional atomizing inhalation device.

Background technique

Nebulization therapy is a common treatment measure for patients with respiratory tract infection, especially for critically ill patients with artificial airways, nebulization inhalation therapy is particularly important. For ordinary patients, although the conventional atomizing inhaler can achieve the purpose of drug atomization, it cannot be used for multiple purposes, and it will cause the backflow of the drug solution with the change of the patient's position, causing the patient to inhale; for mechanical ventilation, artificial For patients with airways, in addition to the above-mentioned complications caused by liquid backflow, liquid particles can damage the expiratory flow sensor of the ventilator and increase medical costs.

Contents of the invention

In summary, the purpose of the present invention is to provide a new multifunctional atomized inhalation device that is more economical, convenient, practical, safe and efficient.

The purpose of the present invention is achieved by the following technologies:

The "T" joint 2 is composed of a horizontal pipe 2I and a vertical pipe 2II; the liquid cup cover 6 integrates a liquid filling port 5, an air inlet 9, a one-way valve 7, an aerosol generator 10 and a hose 11;

There are two sealing rings 2III between the "T" type joint horizontal pipe 2I and the "T" type joint vertical pipe 2II;

The "T" joint horizontal pipe 2I is a hollow structure at the junction with the "T" joint vertical pipe 2II;

The "T" joint vertical pipe 2II can be rotated perpendicular to the "T" joint horizontal pipe 2I;

A detachable filter screen 3 is installed between the "T" joint 2 and the extension tube 4, the filter screen 3 can pass through the gas but not the mist;

The liquid filling port 5 is a standard screw interface, which can be connected to infusion sets, pump tubes and syringes, etc. The liquid filling port cap 15 is covered on the liquid filling port 5, which can be replaced by ordinary standard heparin caps;

There is a sand ball 12 at the lower end of the flexible pipe 11, so that the lower end of the flexible pipe 11 can always be at the lowest point of the liquid cup;

Liquid volume scale is marked on the liquid cup 8, and the unit is milliliter (ml);

The one-way valve 7 is installed on the partition 14; the aperture of the one-way valve 7 is equal to the filling port 5;

Advantage of the present invention and beneficial effect:

1. The present invention has multi-purpose functions: it can be used for nebulization inhalation of patients with artificial airways such as air intubation or tracheotomy, off-line respiratory function exercise, continuous airway humidification when off-line, and nebulization inhalation treatment of ordinary patients.

2. During the use of the present invention, the atomized liquid is sealed, so that it will not pour into the airway of the patient to cause aspiration due to the change of the patient's body position, and will not cause waste of medicine due to pouring out the liquid medicine.

3. The present invention has a detachable filter screen, which can filter mist droplets. When the patient is inhaled by atomization with the machine, the mist droplets will not enter the ventilator and damage the flow sensor of the ventilator.

4. The "T" joint of the present invention is rotatable, which can prevent the liquid cup from standing upside down and prevent the atomized liquid from flowing backward.

5. During the use of the present invention, the sand ball will carry the hose to change its position with the gravity, and it will always be at the lowest point of the liquid cup to ensure continuous generation of aerosol.

detailed description

The present invention will be further described below in conjunction with accompanying drawing:

As shown in Figure 1, a new multifunctional atomized inhalation device,

Example

When using, the operator first chooses different usage methods according to different patients:

Ordinary patients: Connect the mouthpiece 1 and the extension tube 4 to the left and right ends of the "T"-shaped joint horizontal tube 2I in sequence, then screw the liquid cup cover 6 and the liquid cup 8 together, and connect them to the "T"-shaped joint vertical At the lower end of the tube 2II, add the atomized drug solution from the liquid filling port 5, flow into the liquid cup 8 through the one-way valve 7, cover the liquid filling port cover 15, and then connect the A end of the gas connecting pipe 13 to the air inlet 9 The B end is connected to the gas source. If the patient needs oxygen therapy to connect to the oxygen, other patients can connect to the air, turn on the gas source, and adjust the flow to produce aerosol. The gas reaches the upper end of the aerosol generator 10, and the inner diameter of the tube It becomes smaller to form a high-speed airflow, and a vortex is generated around it to drive the liquid medicine from the hose 11 into the aerosol generator 10. The high-speed airflow impacts the liquid medicine to generate aerosol, which is sprayed from the lower end of the aerosol generator 10 and reaches from bottom to top. Put mouth 1 in mouth, instruct the patient to put mouth 1 in mouth, inhale through mouth, exhale through nose, and take a deep breath. When the atomization is completed, remove the device, and the operation is over.

Patients with artificial airway: the right end of the horizontal tube 2I of the "T" connector is connected to the extension tube 4, and the filter screen 3 is placed between the two when atomizing with the machine, and the lower end of the vertical tube 2II of the "T" connector is connected to the liquid cup cover 6 and covered On the liquid cup 8, add the atomized medicinal liquid from the liquid filling port 5. If continuous airway humidification is required for offline respiratory function exercise, the humidified liquid can also be continuously dripped in small doses through the infusion set or whatever Or pump it in, the liquid flows into the liquid cup 8 through the one-way valve 7, cover the liquid filling port cover 15, no need to add a cover when the offline breathing function exercise needs continuous airway humidification, and then connect the A end of the gas connection tube 13 to At the air inlet 9, the B end is connected to the air source. The patient can be connected to oxygen for offline use, and air or oxygen can be connected to the patient for use with the machine. At this time, the device has been integrated. Connect the patient's artificial airway, and connect the right end of the extension tube 4 to the "Y" connector of the ventilator pipeline when the machine is nebulized. The inner diameter of the tube becomes smaller to form a high-speed airflow, and a vortex is generated around to drive the liquid medicine from the hose 11 into the aerosol generator 10. The high-speed airflow hits a small amount of liquid medicine to generate aerosol, which is sprayed out from the lower end of the aerosol generator 10. Then it goes up to the horizontal tube 2I of the "T" joint, enters the airway with the patient's inhalation, and overflows with the patient's exhalation. The patient with the machine is equipped with a filter 3, and the aerosol is adsorbed on it, so replace it if necessary. Filter screen 3, when the atomization of the medicinal liquid is completed, the device is removed, and patients who take off-line respiratory function exercise continue to use it until it is no longer needed, and the operation is over.

If the device is tilted or inverted due to the support of foreign objects, the one-way valve 7 will be closed due to liquid pressure or gravity, and the liquid will not flow out. The hose 11 enters the aerosol generator 10 and continues to work.
