Abstract

A nebulizer kit is provided with a case body (110), a molded flow path body (130), an external air inlet tube (134), a compressed air inlet tube (114), a molded nebulizing unit body (120), and a connecting member (150) which connects the molded flow path body (130) and the molded nebulizing unit body (120). The molded flow path body (130), the external air inlet tube (134), the molded nebulizing unit body (120), and the connecting member (150) are integrally formed. When the molded flow path body (130) is not mounted on the case body (110), the connecting member (150) is not deformed, and a baffle section (122) is disposed at a position lower than the external air inlet tube (134). When the molded flow path body (130) is mounted on the case body (110), the connecting member (150) is deformed so as to become shorter in the longitudinal direction by the force applied to the compressed air inlet tube (114) by a molded liquid suction tube (124). The number of components in the nebulizer kit is reduced as some of the components which make up the kit are integrated.

Description

Nebulizer kit and nebulizer

This invention relates to a nebulizer kit and a nebulizer.

Nebulizers generate aerosols by atomizing liquids such as water, saline, or chemicals that treat diseases such as bronchi. Usually, a nebulizer has a nebulizer kit that generates aerosol. As a document disclosing a nebulizer kit, for example, Japanese Patent Laid-Open No. 06-285168 (Patent Document 1) is cited.

A general nebulizer kit 1000 will be described with reference to FIG. In the nebulizer kit 1000, the atomizing portion forming body 220 is accommodated and arranged inside the case body 210. The atomization part forming body 220 includes a liquid absorption pipe formation part 224 having an opening 224a formed at the top, a baffle part 222 positioned immediately above the opening 224a, and a baffle from the outer surface of the liquid absorption pipe formation part 224. Baffle support portion 223 extending toward the side of portion 222.

An outside air introduction pipe 234 communicating with the opening of the aerosol discharge port 232 is provided on the bottom surface of the flow path forming body 230 attached to the upper portion of the case body 210. The atomization part M is formed between the baffle part 222 and the upper end part 214 a of the compressed air introduction pipe 214. In the atomization part M, the compressed air introduced into the compressed air introduction pipe 214 is sprayed from the upper tip part 214 a of the compressed air introduction pipe 214 toward the baffle part 222.

At that time, the liquid (not shown) sucked up from the storage part 216 to the vicinity of the atomizing part M by the action of the negative pressure generated in the atomizing part M is transferred to the atomizing part M by the action of the negative pressure described above. It is sprayed up and sprayed toward the baffle portion 222 together with the compressed air. The liquid collides with the baffle portion 222 and changes to atomized particles (fine droplets) (not shown). Atomized particles are imparted to the outside air introduced into the case body 210, and aerosol is generated inside the case body 210. The aerosol is discharged to the outside through the aerosol discharge port 232.

Incidentally, in the nebulizer kit 1000, the case body 210, the atomizing portion forming body 220, and the flow path forming body 230 are separately configured as three parts. In the nebulizer kit 1000, as a result of the large number of parts, there is a problem that not only the manufacturing cost becomes high, but each member is easily lost.

The baffle support portion 123 connects the side portion of the baffle portion 122 and the pedestal portion 123a. The baffle support part 123 supports the baffle part 122 so as to be positioned above the opening part 124a.

The connecting member 150 is provided so as to hang in a substantially L-shaped cross section from the bottom surface 130 a of the flow path forming body 130 toward the outer surface 124 b of the liquid suction pipe forming portion 124. The connecting member 150 can be deformed so that the length in the longitudinal direction is shortened. The lower front end side of the connecting member 150 extends along the lower surface of the pedestal portion 123 a and is connected to the outer surface 124 b of the liquid suction pipe forming portion 124.

As shown in FIG. 5, the connecting member 150 may be provided with a plurality of thin refracting portions 151 arranged along the longitudinal direction of the connecting member 150. The connecting member 150 is provided so as to hang down from the surface or lower end of the tube wall 134b of the outside air introduction tube 134 toward the outer surface 124b of the liquid suction tube forming portion 124 in a substantially L-shaped section or a substantially C-shaped section. It may be.

A compressed air introduction pipe 114 is provided on the bottom surface of the case body 110 so as to extend in the vertical direction. The compressed air introduction tube 114 has a substantially conical shape, and the upper tip portion 114a of the compressed air introduction tube 114 is formed in a tapered shape toward the tip opening portion 114b. The tube 12 is attached to the lower end portion of the compressed air introduction tube 114. The compressed air introduction pipe 114 introduces compressed air sent out from the compressor through the compressed air blowing port 11 (see FIG. 1) and the tube 12 into the case body 110.

A storage portion 116 is provided around the portion of the case body 110 where the compressed air introduction pipe 114 is formed. The storage unit 116 temporarily stores liquids (not shown) such as chemicals and vaccines for curing diseases such as water, saline, and bronchi.

The atomization part forming body 120 is disposed inside the case body 110 as the flow path forming body 130 is attached to the case body 110. The atomization part forming body 120 is placed so that the liquid absorption pipe forming part 124 of the atomization part forming body 120 covers the upper tip part 114 a of the compressed air introduction pipe 114. The tip opening 114b of the compressed air introduction pipe 114 is exposed from the opening 124a of the liquid suction pipe forming part 124 in the atomizing part forming body 120 and faces the baffle part 122 of the atomizing part forming body 120.

(Operation of connecting member 150)
The operation of the connecting member 150 when the flow path forming body 130 is attached to the case body 110 will be described with reference to FIGS. The connection member 150 in FIGS. 5 and 6 is in a state before the flow path forming body 130 is attached to the case body 110. The connecting member 150 in FIG. 7 is in a state after the flow path forming body 130 is attached to the case body 110.

As shown in FIG. 5 and FIG. 6, in a state before the flow path forming body 130 is attached to the case body 110, the connecting member 150 is not deformed so that the length in the longitudinal direction is shortened. The connecting member 150 has the longest length, and the baffle portion 122 is positioned below the lower end 134a of the outside air introduction pipe 134.

This state can also be realized by integral molding of the flow path forming body 130, the outside air introduction pipe 134, the atomizing portion forming body 120, and the connecting member 150. Specifically, the baffle part 122 is positioned below the lower end 134 a of the outside air introduction pipe 134 (in other words, a gap is formed between the lower end 134 a of the outside air introduction pipe 134 and the upper end of the baffle part 122. This state is feasible (by forming S (see FIG. 6)).

In addition, before the flow path forming body 130 is attached to the case body 110, the baffle part 122 is positioned above the lower end 134 a of the outside air introduction pipe 134 (the baffle part 122 enters the outside air introduction pipe 134. Cannot be achieved by integral molding. The reason is that the baffle part 122 and the outside air introduction pipe 134 are three-dimensionally overlapped.

The flow path forming body 130 is attached to the case body 110 in a state where the baffle portion 122 is located below the lower end 134a of the outside air introduction pipe 134. The liquid absorption pipe forming part 124 of the atomizing part forming body 120 covers the upper tip part 114a of the compressed air introduction pipe 114 (not shown in FIG. 6). The liquid absorption pipe forming part 124 of the atomizing part forming body 120 is pressed upward by the upper tip part 114 a of the compressed air introduction pipe 114. By this pressing, the connecting member 150 is bent mainly at the refracting portion 151 and deformed so that the length in the longitudinal direction is shortened.

As shown in FIG. 7, the baffle portion 122 moves upward toward the inside of the outside air introduction pipe 134 as the connecting member 150 is deformed. At this time, the baffle portion 122 may be configured to completely enter (include) the outside air introduction pipe 134. The degree (depth) of the baffle part 122 entering the outside air introduction pipe 134 may be adjusted by changing the length of the connecting member 150, or the liquid absorption pipe forming part of the atomization part forming body 120. It may be adjusted by changing the attachment position (attachment height) of the baffle part 122 with respect to 124.

(Aerosol generation and discharge)
With reference to FIG. 8, how the aerosol is generated and discharged in the nebulizer kit 100 in which the flow path forming body 130 is attached to the case body 110 as described above will be described. The arrows shown by broken lines in FIG. 8 indicate the flow of compressed air (outside air) sent out from the main body 10 (see FIG. 1) of the nebulizer 1, and the arrows shown in white indicate the flow of outside air introduced from the pressure adjustment gap 101. The black arrows indicate the aerosol discharge flow.

The liquid absorption pipe is constituted by a gap between the liquid absorption pipe forming portion 124 and the upper end portion 114 a of the compressed air introduction pipe 114. The liquid W stored in the storage unit 116 is sucked up until it reaches the vicinity of the atomizing unit M by the action of negative pressure by blowing compressed air, which will be described later.

The atomization part M is formed between the upper tip part 114 a of the compressed air introduction pipe 114 and the baffle part 122. In the atomization part M, the compressed air introduced into the compressed air introduction pipe 114 by the main body 10 of the nebulizer 1 is sprayed from the upper tip part 114 a of the compressed air introduction pipe 114 toward the baffle part 122. At that time, the liquid W sucked up to the vicinity of the atomization part by the action of the negative pressure generated in the atomization part M is blown up to the atomization part M by the action of the negative pressure described above, and the baffle part 122 together with the compressed air. It is sprayed toward.

By this action, the liquid W collides with the baffle portion 122 to become fine droplets and become mist-like particles. The mist-like particles are introduced into the inside of the case body 110 (by the main body 10 of the nebulizer 1 described above). Aerosol is generated inside the case body 110 by being applied to the introduced outside air and the outside air introduced from the pressure adjusting gap 101 described later based on the exhalation operation of the user.

The flow path forming body 130 and the cap body 140 are positioned and arranged above the atomization part forming body 120. The flow path forming body 130 partitions the space inside the case body 110 and forms a flow path through which airflow flows. A gap provided between the flow path forming body 130 and the cap body 140 forms a pressure adjusting gap 101 that communicates the space in the nebulizer kit 100 with the outside.

The space inside the case body 110 is divided into a central portion and a peripheral portion by the outside air introduction pipe 134 provided at the lower part of the flow path forming body 130, and the outside air introduction path 102 is defined by the inside of the outside air introduction pipe 134, The aerosol transport path 103 is defined by the area surrounded by the outside of the outside air introduction pipe 134 and the case body 110.

The outside air introduction path 102 is a flow path for guiding the outside air flowing in from the pressure adjustment gap 101 to the atomizing section M, and the aerosol transport path 103 sends the aerosol generated in the atomizing section M to the aerosol discharge port 132. It is a flow path for guiding to. With this configuration, the aerosol is discharged from the outside air introduction path 102 toward the aerosol discharge port 132.

(Action / Effect)
In the nebulizer kit 1000 (see FIG. 13) described at the beginning, the flow path forming body 130 and the outside air introduction pipe 134 are integrally molded, but the atomizing portion forming body 120 is configured separately from these. .

On the other hand, in the nebulizer kit 100 of the present embodiment, the atomization part forming body 120, the flow path forming body 130, the outside air introduction pipe 134, and the connecting member 150 are integrally molded. Compared to the nebulizer kit 1000 at the beginning, not only the manufacturing cost is low because the number of parts is small, but also each member (particularly the atomized portion forming body 120) is prevented from being lost.

Japanese Patent Laid-Open No. 06-285168 (Patent Document 1) described at the beginning discloses an embodiment in which a part of the components of the nebulizer kit is integrally molded. However, in the nebulizer kit in the publication, the relative positional relationship between the atomizing section where the mist particles are generated and the outside air introduction pipe is fixed. Since the atomizing section and the outside air introduction pipe are separated from each other, the spray efficiency is not good and the diameter of the generated particles is large. In addition, it is difficult to clean the atomizing section and the outside air introduction pipe.

On the other hand, in the nebulizer kit 100 of the present embodiment, when the flow path forming body 130 is attached to the case body 110, the baffle portion 122 is moved upward toward the inside of the outside air introduction pipe 134 by the deformation of the connecting member 150. Configured to move in the direction. Since the relative distance between the atomizing section M and the outside air introduction pipe 134 is reduced, not only the spray efficiency is increased, but also atomized particles (aerosol) having a smaller particle diameter can be generated. By removing the flow path forming body 130 from the case body 110, the baffle portion 122 and the compressed air introduction pipe 114 are exposed. It is also easy to wash them.

Furthermore, in the nebulizer kit 100 of the present embodiment, when the flow path forming body 130 is attached to the case body 110, the baffle portion 122 is configured to enter the inside of the outside air introduction pipe 134, whereby the spray efficiency is reduced. It is also possible to improve and produce atomized particles having a smaller particle size.

[Other configuration of the first embodiment]
The connecting member 150 may be configured to be plastically deformed by attaching the flow path forming body 130 to the case body 110. By attaching the flow path forming body 130 to the case body 110, the connecting member 150 is bent plastically. Even after the flow path forming body 130 is removed from the case body 110, the connecting member 150 is kept bent (permanently deformed).

Even if the flow path forming body 130 and the case body 110 are placed in a disassembled state, whether the nebulizer kit 100 is used or not is determined depending on whether or not the connecting member 150 is bent. It becomes possible to do. By not using a used nebulizer kit according to the determination, it is possible to prevent the occurrence of sanitary problems such as secondary infection.

[Embodiment 2]
The nebulizer kit 100a in the present embodiment will be described with reference to FIGS. Here, only differences from the nebulizer kit 100 according to the first embodiment will be described.

Referring to FIG. 9, the nebulizer kit 100 a has an elevating mechanism 160 at the joint between the opening 110 c of the case body 110 and the flow path forming body 130. The elevating mechanism 160 can change the relative positional relationship between the case body 110 and the flow path forming body 130 in the vertical direction (height direction).

The elevating mechanism 160 is configured, for example, by forming an inner peripheral surface constituting the opening 110c of the case body 110 in a female screw shape and forming an outer peripheral surface of the flow path forming body 130 closing the opening 110c in a male screw shape. Can be done. As the flow path forming body 130 rotates relative to the case body 110 in the circumferential direction, the flow path forming body 130 moves relative to the case body 110 in the vertical direction of the drawing. Along with this movement, the relative position in the height direction between the baffle portion 122 and the outside air introduction pipe 134 is changed.

The connecting member 150 in the nebulizer kit 100a is formed in a leaf spring shape, for example, and can be elastically deformed in the longitudinal direction. In a state in which the flow path forming body 130 is fitted most deeply into the case body 110 (state shown in FIG. 9: first state), the connecting member 150 causes the atomizing portion forming body 120 to be inserted into the compressed air introduction pipe 114. Is biased downward (pressed). The distance between the baffle part 122 and the lower end 134a of the outside air introduction pipe 134 is a dimension L1. In this state, the diameter of the atomized particles generated in the atomizing part M is smaller than the diameter of the atomized particles generated in the atomized part M in the state shown in FIGS.

Referring to FIG. 10, the flow path forming body 130 and the case body 110 are rotated by rotating the flow path forming body 130 with respect to the case body 110 in the circumferential direction (direction in which the flow path forming body 130 is removed from the case body 110). Move in a direction away from each other (second state). In addition, since the atomization part formation body 120 is urged | biased with respect to the compressed air introduction pipe | tube 114 by the connection member 150, the relative position in the up-down direction of the atomization part formation body 120 and the compressed air introduction pipe | tube 114 changes. Absent.

The distance between the baffle part 122 and the lower end 134a of the outside air introduction pipe 134 is reduced, and the distance is a dimension L2 (dimension L1> dimension L2). The diameter of the atomized particles generated in the atomizing section M is larger in the second state (the state shown in FIG. 10) than in the first state (the state shown in FIG. 9).

Referring to FIG. 11, the flow path forming body 130 and the case body are further rotated by rotating the flow path forming body 130 in the circumferential direction (the direction in which the flow path forming body 130 is removed from the case body 110) with respect to the case body 110. 110 further moves in a direction away from each other (third state). Since the atomization part formation body 120 is urged | biased with respect to the compressed air introduction pipe | tube 114 by the connection member 150, the relative position in the up-down direction of the atomization part formation body 120 and the compressed air introduction pipe | tube 114 does not change.

The distance between the baffle portion 122 and the lower end 134a of the outside air introduction pipe 134 is further reduced, and the distance is a dimension L3 (dimension L2> dimension L3). The diameter of the atomized particles generated in the atomizing section M is larger in the third state (the state shown in FIG. 11) than in the second state (the state shown in FIG. 10).

According to the nebulizer kit 100a, the diameter of the particles to be sprayed is changed according to the application and desired efficacy, such as the type and nature of the drug used (viscosity, etc.), the patient's symptoms and the location of the affected area, or the patient's age It becomes possible to do. There is no need to prepare a plurality of nebulizer kits according to the desired particle diameter, and nebulizer particles (aerosols) having a desired size can be ejected by a single nebulizer kit, thereby reducing the manufacturing cost. It becomes possible.

According to the nebulizer kit 100a, an optimal drug solution can be administered to a patient by selecting an appropriate particle size. For example, it is desirable to spray an aerosol having a relatively small particle size for asthma and the like. For administration to expectorants and throats, it is desirable to spray an aerosol with a relatively medium particle size. For applications such as nasal washing, it is desirable to spray a relatively large particle size aerosol. Moreover, according to the nebulizer kit 100a, it becomes possible to respond flexibly and quickly to new diseases and various new drugs.

About the intensity | strength (rigidity) of the connection member 150 for urging the atomization part formation body 120 with respect to the compressed air introduction pipe | tube 114, the atomization part formation body 120 is with the atomized particle ejected from the opening part 124a. It should be designed to the extent that it does not float.

When the particle diameter is increased or decreased by rotation of the flow path forming body 130 with respect to the case body 110, the relative positions of the flow path forming body 130 and the case body 110 (on the surface of the flow path forming body 130 and / or the surface of the case body 110 ( It is advisable to provide a scale indicating the amount of rotation). By adjusting the scale to a predetermined position, the vertical positions of the flow path forming body 130 and the case body 110 are determined, and the diameter of the sprayed mist particles may be set to a predetermined desired value. It becomes possible.

The lifting mechanism 160 is not limited to the above-described mode, and the flow path forming body 130 is fitted into the opening 110c of the case body 110, and the opening 110c of the case body 110 and the outer peripheral surface of the flow path forming body 130 slide in the vertical direction. It may be configured to move. Also in this case, it is preferable to arrange scales in the vertical direction. By adjusting the scale to a predetermined position, the vertical positions of the flow path forming body 130 and the case body 110 are determined, and the diameter of the sprayed mist particles may be set to a predetermined desired value. It becomes possible.

A convex portion may be provided on the outer peripheral surface of the flow path forming body 130 at regular intervals, and a concave portion may be provided on the inner peripheral surface of the case body 110 so as to correspond to the convex portion. When rotating (sliding) the flow path forming body 130 with respect to the case body 110, the amount of rotation (or sliding amount) is felt by the user due to the change in resistance caused by the convex and concave portions generated at regular intervals. It becomes possible to make it.

[Embodiment 3]
The nebulizer kit in the present embodiment will be described with reference to FIG. Here, only differences from the nebulizer kit 100 according to the first embodiment will be described.

In the nebulizer kit of the present embodiment, the locking portion 122a is provided outside the baffle support portion 123 in the atomization portion forming body 120, and the locking portion 134c is provided on the inner peripheral surface 136 of the outside air introduction pipe 134. Yes. The support portion 124c that supports the locking portion 122a can be elastically bent inward (inner side in the cylinder radial direction of the outside air introduction tube 134) by a notch 122b provided between the support portion 123 and the baffle support portion 123. Yes.

When the flow path forming body 130 is attached to the case body 110 (not shown), the baffle portion 122 moves in the direction of entering the outside air introduction pipe 134. When the locking portion 122a of the baffle support portion 123 contacts the inner peripheral surface 136 of the outside air introduction tube 134, the support portion 124c is bent and the locking portion 122a is elastically displaced toward the inside.

When the baffle part 122 moves so as to further enter the inside of the outside air introduction pipe 134, the locking part 122a does not come into contact with the inner peripheral surface 136, and is displaced to the outside again by the restoring force of the support part 124c. The locking part 122 a is locked to the locking part 134 c of the outside air introduction tube 134. After the locking, the locking state between the locking part 122a and the locking part 134c is substantially unreleasable, and the baffle part 122 cannot be extracted from the outside air introduction pipe 134. (It has become a so-called inlay.)

According to the nebulizer kit in the present embodiment, since it is impossible to extract these after use, it is possible to determine whether or not the nebulizer kit is unused. By not using a used nebulizer kit according to the determination, it is possible to prevent the occurrence of sanitary problems such as secondary infection.

The configuration in the present embodiment can also be applied to the nebulizer kit 100a in the second embodiment described above. Specifically, the vertical length M1 of the support portion 124c may be longer than the vertical length M2 of the locking portion 134c (length M1> length M2). Even after the locking portion 122a is locked to the locking portion 134c, the baffle portion 122 is further movable in the vertical direction. The elevating mechanism 160 in the second embodiment described above can adjust the size between the baffle portion 122 and the lower end 134a of the outside air introduction tube 134 to adjust the particle diameter of the mist-like particles.

As mentioned above, although each embodiment of the present invention was described, it should be thought that the embodiment indicated this time is an illustration and restrictive at no points. The scope of the present invention is defined by the terms of the claims, and is intended to include any modifications within the scope and meaning equivalent to the terms of the claims.
