Abstract

The utility model discloses an inhalation drug delivery and humidifier controlled release through oxygen inhalation, which is composed of a window direct-viewing drug delivery regulator, a drug solution atomization chamber and a miniature ultrasonic atomization device. Through the medicine bottle joint (1), the adjustment switch (2) and the observation window (3), the medicine can be added conveniently and the dosage can be controlled and released intuitively. The aluminum alloy cavity (9) with multiple grooves on the surface is beneficial to heat dissipation of the built-in ultrasonic atomizer and makes it possible to miniaturize it. A movable interface (4) and an outlet (6) are provided to facilitate the supporting use and popularization of the existing oxygen inhalation device.

Description

Controlled-release inhalation via oxygen inhalation and humidifier

The utility model relates to the field of medical equipment, in particular to an oxygen inhalation controlled-release inhalation medicine and humidifier connected to an oxygen inhaler.

Inhalation administration has the advantages of convenience, quickness and local application, and is suitable for respiratory tract infection, asthma, anesthesia and some first aid applications. The current inhalation drug delivery device is bulky, and it is inconvenient to add and change the drug at any time. The dosage is mainly adjusted by the amount of atomization or the size of the wind force. The operability is poor, and it is difficult to meet the accurate and lasting control of the dosage and speed in clinical treatment. requirements. Oxygen inhalation is the most basic treatment method in clinical practice. Simple oxygen inhalation for a long time often causes nasal cavity dryness, and there is no good clinical solution. Chinese patent ZL99218257.6 discloses an oxygen inhalation drug delivery regulator that organically combines inhalation drug delivery and oxygen inhalation, and achieves the purpose of inhalation therapy by inhaling volatile medicinal liquid or atomized medicinal liquid with oxygen, which simplifies Inhalation administration procedure. However, the use of this device cannot intuitively and accurately grasp the dosage and speed of administration, which limits its wide clinical application.

The purpose of the utility model is to provide an inhalation drug delivery device which can accurately and intuitively control the dosage and speed of inhalation administration, can be conveniently added at any time, and can be matched with the existing oxygen inhalation device for popularization and promotion, and also has a humidification function.

The technical scheme that realizes the utility model purpose is:

The utility model is composed of a window-type controlled-release inhalation drug delivery regulator, a liquid medicine atomization chamber, a miniature ultrasonic atomizer and an oxygen inlet and outlet joint. On the top of the liquid medicine atomization chamber, there is a device for adding medicine, which is composed of a medicine bottle connector, an adjustment switch and a transparent observation window, and can directly adjust the speed of drug administration; on the upper part and side of the liquid medicine spray chamber, there are inlet and outlet ports, which can It is connected in series with the oxygen inhaler; the connection between the atomization chamber and the water tank is provided with a hemispherical medicine cup that separates the upper and lower chambers; the aluminum alloy chamber with multiple grooves is carved on the sealing surface under the water tank to make the built-in ultrasonic atomizer The device is beneficial to heat dissipation and cooling; the utility model can be equipped with a miniature pneumatic device, which can be used conveniently without an oxygen absorbing device.

Below in conjunction with accompanying drawing, the utility model is further described;

The utility model is composed of a window-type controlled-release inhalation drug delivery regulator, a liquid medicine atomization chamber, a micro-ultrasonic atomizer and an oxygen inlet and outlet interface. When in use, it is movably connected with the oxygen inhaler 11 through the interface 4 and the outlet 6 . Insert the medicine bottle 13 containing the medicine liquid upside down into the needle-shaped joint 1, and adjust the switch 2 to observe through the transparent window 3 so that the medicine liquid enters the medicine liquid atomization chamber 5 at the required drop rate and falls into the bottom of the hemispherical medicine cup 7 . If it is a volatile medicinal liquid, it can volatilize by itself and mix with the oxygen flow; if it is a non-volatile medicinal liquid, the micro-ultrasonic nebulizer 10 must be activated. Ultrasonic wave passes through the conduction medium of the water in the water tank 8 to atomize the medicine liquid in the medicine cup 7 made of thin film, mixes with the oxygen flow and releases it from the outlet 6 to be inhaled by the patient. When the liquid medicine in the atomization chamber 5 volatilizes naturally or the amount of passive atomization is greater than the dose controlled by the switch 2, the dosing drop rate observed from the observation window 3 is the actual inhalation dosing speed, and the operator passes through Accurate and intuitive control of the total amount and speed can achieve the purpose of controlled release drug delivery. Usually, the ultrasonic nebulizer 10 will generate heat during operation. The utility model embeds the ultrasonic nebulizer 10 in the ventilated aluminum alloy cavity 9 engraved with a plurality of grooves on the surface. The direct cooling of the water tank 8 can ensure the normal operation of the ultrasonic nebulizer 10 for a long time. At the same time, the miniaturization of the ultrasonic device required by the utility model can be achieved because the fan cooling device required by the usual ultrasonic atomizer is omitted and the external AC adapter is installed. Under the condition of family or no oxygen bottle, the utility model can continue to be used when the interface 4 is equipped with a miniature pneumatic device 12 . The utility model can add pure water to meet the purpose of simple humidification and oxygen absorption.
