Description

  TECHNICAL FIELD The present invention relates to an aerosol device for injecting medicines for ingestion used in the medical field, deodorants for space, fragrances, insecticides, and other aerosol contents into a fine mist. Is.

  2. Description of the Related Art Conventionally, in the medical field, a technique shown in Patent Document 1 is known as a medicine for injecting a medicine for ingestion into a fine mist. This prior art is generally referred to as a nebulizer, and its configuration is such that a medicine container is provided in the lower part of the central axis of the container, and a cylinder having a driving gas flow passage is provided in the vertical direction. A driving gas jet port is formed at the upper end of the flow passage. In addition, a collision wall is provided so as to face the jet port and to collide and pulverize the medicine injected from the jet port. In addition, an introduction path provided on the outer periphery of the cylindrical body is connected to the ejection port, and a lower end of the introduction path is connected to the medicine container.

And the medicine which was crushed by this collision and whose particle diameter was refined can be ejected to the outside through a discharge interval provided at the upper end of the storage container. In this way, by aiming to reduce the particle size of the drug and injecting it, the drug is sufficiently delivered to the respiratory organ of the user, and the inhalation effect of the drug is enhanced.

JP 2006-75385 A

  However, in the above prior art, since the medicine is ejected upward together with the propelling gas, not only the medicine collided with the collision wall and pulverized and the particle diameter is reduced, but also the particle diameter is reduced. However, all the chemicals that are insufficient are caused to flow upward by the jet pressure. Therefore, a drug with a large particle size is released to the outside together with a drug with a finer particle size, and it becomes difficult to sufficiently deliver the drug to the user's respiratory organ. It was to decline.

  In the above prior art, as described above, since the medicine storage portion and the outside air are always in communication with each other through the discharge port, if the medicine is stored in the storage portion, the medicine in the storage portion There is a risk of oxidative deterioration or contamination due to contact with the outside air. For this reason, every time the user uses the medical solution, the storage unit must be replenished with the chemical solution, and the work burden on the user is large.

  Therefore, the present invention is intended to solve the problems as described above, and it is possible to inject only the aerosol content having a fine particle diameter to the outside, and it is not necessary to replenish the chemical every time it is used. An object of the present invention is to obtain an aerosol content injection device capable of reducing the work burden on the user.

  In order to solve the above-described problems, the present invention forms a communication passage in the pushbutton body that communicates with the stem of the aerosol container filled with the aerosol contents, and forms an aerosol outlet at the tip of the communication path. Yes. In addition, a collision wall for colliding and pulverizing the aerosol contents is arranged facing this jet outlet, and the particle diameter is located at a position farther away from the jet outlet than the collision wall on both sides of the collision wall. A partition wall is provided to allow a large aerosol content to abut. In addition, a discharge interval for discharging aerosol contents having a small particle diameter to the outside is formed between the upper ends of the partition wall and the collision wall and the inner periphery of the injection cylinder protruding from the side surface of the push button body, and the partition wall A retention portion for retaining the aerosol content having a large particle diameter that has been struck and dropped is provided below the collision wall. Further, this staying part is connected to the jet port through an introduction path formed separately from the communication path in the push button body.

  And at the time of the injection of the aerosol contents, the ejector action generated at the jet outlet when jetting the aerosol contents is used to suck and introduce the aerosol contents of the staying portion to the jet outlet via the introduction path, It can be ejected from the spout along with the aerosol contents introduced from.

  Further, the staying portion may be formed inside a cylindrical body fixedly connected to the lower end of the push button. By forming in this way, it becomes possible to form the ejection port and the retention portion in an airtight manner. In this case, when the aerosol content having a large particle diameter falls into the retention portion, the aerosol content is It is possible to prevent contact with outside air. Therefore, it is possible to prevent the aerosol contents from coming into contact with the outside air to be oxidized and deteriorated or contaminated during the fall.

  Further, the staying portion may be recessed at the upper end of the aerosol container. By forming in this way, it becomes possible to use the surface concave portion of the mountain cup of the aerosol container as a staying portion, to reduce the protruding height above the push button body, and to reduce the size of the device. .

  In addition, the collision wall may have a plane that is perpendicular to the injection direction of the aerosol content from the ejection port, with the collision surface facing the ejection port. By forming in this way, it becomes possible to reliably collide and crush the aerosol content ejected from the ejection port against the collision wall, so that the aerosol content can be efficiently miniaturized. .

  The partition wall may be formed integrally with the collision wall. By forming the partition wall integrally with the collision wall in this way, the number of constituent members can be reduced, and the manufacturing cost of the device can be reduced.

  The invention of the present application is configured as described above, and the collision wall is arranged facing the jet outlet, and the particle diameter is set at a position farther away from the jet outlet than the collision wall on both sides of the collision wall. A partition wall capable of abutting a large aerosol content is provided, and the particle diameter is small and the mass is reduced through a discharge interval provided between the upper end of the partition wall and the inner periphery of the injection cylinder protruding from the side surface of the push button body. Only the aerosol content with a small size can be discharged to the outside. Therefore, a part of the aerosol contents injected from the jet nozzle did not collide with the collision wall, or even if it collided with the collision wall, the pulverization was insufficient, and the particle diameter remained large and flowed out to both sides of the collision wall. Even in such a case, the aerosol content having a large particle diameter descends due to its large mass, falls down by its own weight before hitting the partition wall or hitting the partition wall, and is collected in the staying portion. And the aerosol content with a large particle diameter collect | recovered by this residence part is suck | introduced and introduced into a jet nozzle using an ejector effect | action, and is again discharged | emitted from a discharge port with the aerosol content introduced from a communicating path. In this way, even if a part of the ejected aerosol content cannot be sufficiently refined in particle size, the aerosol content having a large particle size is recovered in the retention part and ejected from the outlet Since it becomes possible to inject again from this, the aerosol content can be used efficiently.

  In addition, since the aerosol content having a large particle size is not discharged to the outside as described above, only the aerosol content having a fine particle size is discharged to the outside through a discharge interval provided above the collision wall and the partition wall. Can be discharged. Therefore, for example, when used for a medical suction device or the like, it becomes possible to discharge only the aerosol content with sufficiently fine particle diameter to the outside, It is possible to reach the respiratory organs sufficiently. In addition, for example, when using the spray device of the present invention for space deodorants, fragrances, insecticides, etc., by spraying a small aerosol content with a small particle size, the aerosol content It becomes possible to lengthen the time that an object drifts in the space, and it is possible to maintain the effect of the aerosol product.

  Further, in the present invention, since the communication path communicating with the stem of the aerosol container is formed in the push button body, and the aerosol outlet is formed at the tip of the communication path, the aerosol content in the aerosol container is formed. Objects do not come into contact with the outside air unless the push button is pressed to open the valve mechanism in the aerosol container. Therefore, there is no possibility that the aerosol contents in the aerosol container come into contact with the outside air to be oxidized or deteriorated, and the product quality can be kept good. In addition, since the aerosol contents are filled in the aerosol container and can be sprayed to the outside through the valve mechanism as needed, it is necessary for the user to fill the aerosol contents every time it is used. It is possible to reduce the work burden on the user.

  1 to 5, the first embodiment of the present invention will be described. (1) is a push button body, which is made of hard plastic or the like. As shown in FIG. A pressing portion (2) is provided on the upper surface, and the stem (5) of the aerosol container (4) is connected to the stem connecting portion (3) provided on the inner surface of the lower end. The valve mechanism (not shown) is opened by pressing the pressing part (2) of the pushbutton body (1) and pushing down the stem (5) in the direction of the aerosol container (4), and the aerosol container (4) This aerosol content can be introduced into the pushbutton body (1). In this specification, for convenience of explanation, the left side in FIG. 1 is the distal end side of the push button body (1) and the right side is the proximal end side.

  Further, the push button body (1) is provided with an aerosol passage (6) for the aerosol contents in the axial direction of the stem (5) continuously to the stem connecting portion (3). Is connected to the base end of the communication passage (7) perpendicular to the ejection passage (6). In addition, an aerosol outlet (8) is formed at the tip of the communication path (7). This spout (8) is formed by opening the side wall of the mounting body (10) mounted on the side surface of the push button body (1), as shown in FIG.

  Moreover, the collision wall (11) for making the aerosol content which spouted from the spout (8) collide and grind | pulverizes faces the said spout (8). As shown in FIGS. 1 and 5, the collision wall (11) fixes the lower end in the injection cylinder (12) protruding from the side surface of the push button body (1) on the mounting body (10) side, and As shown, the collision surface (13) facing the ejection port (8) is a plane perpendicular to the injection direction of the aerosol contents from the ejection port (8). By forming in this way, the aerosol content injected from the jet outlet (8) can be reliably collided with the collision wall (11) and crushed. In addition, the aerosol content can be efficiently miniaturized.

  Further, the collision wall (11) is formed only at the center in the vertical direction of the injection cylinder (12) so as to face the injection port (8), and both sides thereof are injected from the injection port (8) as shown in FIG. As a flow part (14) for flowing the aerosol contents that collided with the collision wall (11), the particle diameter is between the upper end of the collision wall (11) and the inner surface of the injection cylinder (12) as shown in FIG. The discharge interval (15) for discharging a small aerosol content to the outside. Thus, by forming the flow part (14) on both sides of the collision wall (11) and the discharge interval (15) above the collision wall (11), respectively, when the aerosol contents to be described later are injected, The flow in the ejection direction of the aerosol contents ejected from the ejection port (8) and colliding with the collision surface (13) of the collision wall (11) can be improved.

  Moreover, as shown in FIG. 3, the aerosol content with a large particle diameter can be abutted on the both sides of the collision wall (11) at positions farther away from the ejection port (8) than the collision wall (11) in the ejection direction. The partition wall (16) is integrally formed with the collision wall (11) in a plane T shape. Thus, by forming the partition wall (16) integrally with the collision wall (11), the number of components is reduced compared to the case where the partition wall (16) and the collision wall (11) are formed separately. Therefore, the manufacturing cost of the device can be reduced.

  In addition, since the aerosol content having a large particle diameter that does not collide with the collision wall (11) or does not pulverize even when it collides with the collision wall (11) has a large mass, it does not collide with the partition wall (16). Falls to the bottom surface (17) of the circulation part (14) or falls to the bottom surface (17) of the circulation part (14) even if it hits the inner surface of the partition wall (16), up to the discharge interval (15) Can't reach.

  Further, as shown in FIG. 1, a retention portion (18) for retaining aerosol contents having a large particle diameter is provided below the collision wall (11). Then, as described above, it collides with the aerosol content having a large particle diameter dropped on the bottom surface (17) of the flow section (14) or the collision surface (13) of the collision wall (11), and from the lower end of the collision surface (13). The aerosol content having a large particle size that drops is dropped to the center of the base end side of the bottom surface (17) of the flow part (14) through a notch part (20) formed as a notch as shown in FIGS. , And can be introduced into the retention part (18).

  Further, in this embodiment, this staying portion (18) is formed inside a cylindrical body (21) fixedly connected to the lower end of the push button body (1) as shown in FIG. By forming the staying portion (18) in the cylindrical body (21) fixedly connected to the lower end of the push button body (1) in this way, the jet port (8) and the staying portion (18) are formed in an airtight manner. It is also possible to do. In this case, it is possible to prevent the aerosol content from coming into contact with the outside air when the aerosol content having a large particle size falls to the retention portion (18). Therefore, it is possible to prevent the aerosol contents from coming into contact with the outside air to be oxidized and deteriorated or contaminated during the fall.

  Further, as shown in FIG. 1, the stay portion (18) is connected to the jet port (8) through an introduction path (22) formed separately from the communication path (7) in the push button body (1). is doing. The introduction path (22) includes a suction path (23) whose lower end is connected to the retention part (18), a suction hole (24) whose one end is connected to the upper end of the suction path (23), and the suction hole ( 24) and the suction interval (25) connected to the other end. As shown in FIGS. 1 and 2, the suction interval (25) is an arrangement interval between the outer peripheral surface of the communication tube (26) forming the communication passage (7) and the inner peripheral surface of the mounting body (10). Forming.

  In order to inject the aerosol contents in the configuration as described above, the stem (5) is moved in the direction of the aerosol container (4) by pressing the pressing portion (2) of the push button body (1). Push down to open the valve mechanism (not shown). Thereby, the aerosol content in the aerosol container (4) is introduced into the communication path (7) via the valve mechanism, the stem (5) and the ejection path (6), and ejected from the ejection port (8). The aerosol content ejected from the ejection port (8) in this way collides with the collision surface (13) of the collision wall (11) arranged facing the ejection port (8) and is pulverized and refined. . And since the aerosol content with a small particle diameter thus refined has a small mass, it flows above the collision wall (11) or the flow part (14), and passes through the discharge interval (15). It is discharged to the outside from the discharge part (19).

  In addition, since the aerosol content having a large particle diameter that does not collide with the collision wall (11) or does not pulverize even when it collides with the collision wall (11) has a large mass, it does not collide with the partition wall (16). Fall on the bottom surface (17) of the circulation part (14) or collide with the inner surface of the partition wall (16) and fall on the bottom surface (17) of the circulation part (14). Not reach. In the present invention, since the aerosol content having a large particle size is not discharged to the outside as described above, only the aerosol content having a fine particle size is separated from the collision wall (11) and the partition wall (16). It becomes possible to discharge to the outside through a discharge interval (15) provided above. Therefore, for example, when used for a medical suction device or the like, it becomes possible to discharge only the aerosol content with sufficiently fine particle diameter to the outside, It is possible to reach the respiratory organs sufficiently. In addition, for example, when the spray device of the present invention is used for a space deodorant, fragrance, insecticide, etc., the aerosol content drifts in the space by spraying the atomized aerosol content. The time can be extended and the effect of the aerosol product can be sustained.

  Further, as described above, the aerosol content having a large particle size dropped on the bottom surface (17) of the flow portion (14) passes through the notch portion (20) formed in the bottom surface (17) of the flow portion (14). Thus, it is introduced into the staying part (18). And the ejector action which arises in an ejection port (8) when the aerosol content in a large particle diameter which retained in this residence part (18) ejects the aerosol content in an aerosol container (4) from an ejection port (8). Using suction, suction is introduced into the ejection port (8).

  And the aerosol content with a large particle diameter sucked and introduced into the ejection port (8) through the introduction path (22) in this way, together with the aerosol content introduced from the communication path (7), the ejection port (8). ) Will erupt from. In the present invention, in this way, even when part of the ejected aerosol content cannot be sufficiently refined in particle size, the aerosol content having a large particle size is retained in the retention part. Since it can collect | recover in (18) and it can inject again from a jet nozzle (8), the efficient use of an aerosol content is attained.

  In the present invention, as described above, the communication passage (7) communicating with the stem (5) of the aerosol container (4) is formed in the push button body (1), and the aerosol is formed at the tip of the communication passage (7). Since the content spout (8) is formed, the aerosol content in the aerosol container (4) presses the push button body (1) and a valve mechanism (not shown) in the aerosol container (4). If it is not opened, it will not come into contact with the outside air. Therefore, there is no possibility that the aerosol contents in the aerosol container (4) come into contact with the outside air to be oxidatively deteriorated or contaminated, and the product quality can be kept good. In addition, the aerosol container (4) is filled with the aerosol contents and can be sprayed to the outside through the valve mechanism as needed, so the user fills the aerosol contents with each use. Therefore, it is possible to reduce the work burden on the user.

  In the first embodiment, as shown in FIG. 1, a staying portion (18) is formed in a cylindrical body (21) integrally connected to the push button main body (1) at the lower end of the push button main body (1). However, in the second embodiment, as shown in FIG. 6, the surface recess (28) formed in advance on the mountain cup (27) connected to the upper end of the aerosol container (4) ) Is used. As described above, by using the surface recess (28) of the mountain cup (27) as the staying portion (18), it is possible to reduce the protruding height of the push button body (1) upward and to reduce the size of the device. It becomes possible.
