Problems solved by technology

Although the spacer is provided with an exhalation port on the face mask, the airflow exhaled by the infant patient will be discharged through the exhalation port of the face mask, but because the face mask does not directly contact with the oral cavity, and the infant patient exhales and inhales Unskilled operation, unable to perform coherent exhalation and inhalation actions, often accompanied by a lot of atomized particles in the exhaled gas, resulting in waste of drugs and low utilization rate
The base of the spacer is provided with a strip-shaped through hole connected with the quantitative aerosol inhaler, which can only be connected with the quantitative aerosol inhaler with its structure, which limits the scope of application of the spacer.
[0005] To sum up, the traditional spacer in the above patent literature can only be used in conjunction with some quantitative aerosols, which limits its application range, and the loss of drugs during use is large, the utilization rate is low, and the delivery volume is low

Embodiment approach

[0043] The main body of the spacer of the present invention is a hollow structure with a large center and small ends. The shape of the spacer main body is not particularly limited, and may be pear-shaped, tubular, oval, spindle-shaped, etc., preferably spindle-shaped. According to an embodiment of the present invention, the main body of the spacer is a hollow spindle-shaped structure. The atomized drug particles are sprayed out through the aerosol spray interface, and sprayed into the main body of the spacer through the spray inlet. At this time, the atomized drug particles enter the main body of the spacer at a faster speed. , It is easy to cause impact on the patient's mouth and cause coughing. Due to the limited volume of the oral cavity, most of the drug particles sprayed into the oral cavity remain on the surface of the oral cavity, causing a large amount of drug waste and easily causing oral streptococcal infection. The present invention chooses the main body structure...

Embodiment 1

[0064] figure 1 It is a structural schematic diagram of a spacer of the present invention; figure 2 It is an explosion diagram of a spacer of the present invention; image 3 It is a schematic diagram of the front structure of a base of the present invention; Figure 4 It is a schematic diagram of the back structure of a base of the present invention; Figure 5 It is a structural schematic diagram of an upper end cap of the present invention; Figure 6 It is a structural schematic diagram of a suction cap of the present invention; Figure 7 It is a structural schematic diagram of a plum-blossom gasket of the present invention.

[0065] Such as figure 1 As shown, the spacer of this embodiment includes a base 2 , a spacer body and a suction cap 6 which are connected in sequence from bottom to top. The bottom of the base 2 is provided with a mist inlet for connecting to an aerosol spray port. The fog inlet is circular and has a wall of the fog inlet. The top of the suction...

Embodiment 2

[0074] Except for increasing the following technical content, all the other are the same as Embodiment 1:

[0075] Such as figure 2 As shown, the spacer of this embodiment also includes a small cap 7 . The small cap 7 is covered on the suction port of the suction cap 6 to keep the suction port clean, prevent bacteria from growing, and reduce the oral infection rate. Such as figure 1 As shown, the outer wall of the small cap 7 is provided with a connecting piece 14; the outer wall of the suction cap 6 near the upper end cap 4 is provided with a boss 15. One end of the connector 14 is connected to the small cap 7 , and the other end is sleeved on the boss 15 to prevent the small cap 7 from being lost.

[0076] When in use, insert the aerosol spray interface into the mist inlet, start the aerosol device, and spray the medicine mist into the mist storage tank. When the patient inhales, a negative pressure is formed in the main body of the spacer, thereby pushing away the peta...

Abstract

The invention discloses a mist storage tank and an inhalation device. The mist storage tank comprises a base sleeve, a base, a mist storage tank main body and a suction cap which sequentially communicate with one another from bottom to top, wherein a mist inlet is formed in the bottom of the base and used for being connected with an aerosol spraying connector, and the mist inlet is provided with a mist inlet wall; an air suction port is formed in the top of the suction cap and used for being sucked by the mouth; the base sleeve is tightly attached to the outer wall and the bottom end face of the base and the mist inlet wall, one portion of the base sleeve extends into the mist inlet to form an extension portion, and the other portion of the base sleeve continues to extend upwards along the mist inlet wall to form a first attaching portion; the inner edge of the extension portion extends upwards to form a second attaching portion; and the first attaching portion and the second attaching portion are arranged to be capable of tightly wrapping the aerosol spraying connector. The mist storage tank can be connected with various aerosol spraying connectors, and medicine loss can be reduced.

Description

technical field [0001] The invention relates to a mist storage tank and an inhalation device. Background technique [0002] A spacer is an adjunct to metered dose inhalation (MDI) inhalation therapy and is used to store aerosols. When the atomized drug particles ejected from the metered spray pass through the spacer tank, the drug particles are fully mixed with the air in the tank and then inhaled by the patient. [0003] CN209075743U discloses a mist storage tank, which includes a tank body, a suction nozzle and a mask. The tank body includes an upper tank body and a lower tank body detachably connected along the bisecting plane of its length direction, and the connection surface of the upper tank body and the lower tank body is Grooves are arranged, and convex ribs are arranged on the connecting surface of the lower tank body and the upper tank body. The outer surface of the upper tank is provided with a quantitative aerosol interface. The quantitative aerosol interface ...
