Description

[Detailed description of the invention] medical spray device Mizumoto EA relates to aerosol devices.

The most common type of aerosol device includes a metal container and a discharge valve. The fluid in the container can be discharged through the nozzle through the outlet valve. It has become. This discharge valve, when actuated, provides a continuous supply of spray liquid. It is also possible to supply the amount of throw M of Rukoyoshi or - times. That's it Even in the case of misalignment, the user has no idea how much fluid remains inside the container. It's never obvious.

Although this does not pose a real problem in many cases, In some cases, such as when a rosol device is used to administer a dose of medicine, It becomes unsatisfactory. One special type of such aerosol device is known There is a type of spray device for medical use in the oral cavity or throat. , the device is capable of ejecting a single predetermined dose of medication each time the device is operated. a holder for an aerosol container designed to dispense; having a nozzle for spraying or atomization through which the dosage is expelled; It is now possible to do so. This aerosol container has a discharge tube and is pressed down. A possible dosage delivery valve is provided, and the delivery pipe is connected to the atomizer nozzle. The aerosol container is mounted within the retainer such that it is received within the recessed portion. Installation or installation is possible. The aerosol container opens outside the holder. The container is inserted and held within the released guiding part, e.g. is pressed downwardly within the guide by applying thumb pressure to the so that the discharge nozzle is pushed towards the inside of the container and Thus - doses are delivered in the spray.

This type of device is useful, for example, for breathing in patients with asthma or other respiratory diseases. Although used to deliver dosages into organ system passageways, these devices used and operated by. Patients should always have an active nebulizer on hand. is often the most important thing to do. In other words, patients should new equipment i.e. at least one new pressurized container before the container is emptied. You need to know when to get it.

These containers are usually made of metal to withstand pressure and are therefore not transparent. The patient can directly see how much medicine is left in the container. Kina (・.

Theoretically, this condition could be achieved by weighing the container or by performing a buoyancy test. When the container is completely empty, it will rise to the surface at a high level, making it easy to detect. can be done. However, it is important to carry out such tests to ensure that new Determine if you can go through a vacation period or even a weekend break without getting a new container. Only relatively few patients can.

According to U.S. Patent Application No. 3,505,870, the user can Providing an aerosol container with a transparent window that allows for the measurement of the amount of It has already been proposed. But this is a very undesirable point on the container itself. Requires renovation.

The invention more particularly provides that for each actuation a single predetermined dosage is obtained. equipped with a non-transparent aerosol container of a type that can be operated as It relates to an aerosol device consisting of a container. The purpose of the present invention is to enable the user to To provide an aerosol device of a type that makes it easy to measure exactly when it is empty. Ru.

The present invention has never before been shown in terms of how many doses an aerosol container can dispense. Automatically perform multiple operations in succession, provided that it is known that This was done on the basis that the above purpose could be achieved by counting. Ru. Basically, the present invention is based on an agent containing a dosage whose number of administrations is known. The selection of a rosol container and the automatic counting of the number of actuations of the drug dose delivery valve were carried out. The combination of be warned by such a method that it is possible to count all the times when there is no time remaining. It's about doing.

In practice, however, aerosol containers of the type relevant to the present invention typically include For example, a sign guaranteeing that the valve contains a dosage of 200 or 400 doses. The present invention is based on the actual practice already carried out. and hence actually emit the volume that a given aerosol container has. Can be easily linked to automatic counting of the number of doses administered, allowing the user to The number of doses actually present in that single container must be known accurately. There is no need to do so.

The user only has to rely on the guaranteed number of doses, and the counter Count up to the remaining fraction of the number of doses given or Just watch them count backwards from number to number.

Therefore, the present invention is based on the above-mentioned general idea, and has the features set forth in claim 1. It is characterized by having the features described in the description part.

Various containers and bottles, the dosage dispensed through the dosing valve device of the medicinal liquid bottle as king It is readily accepted that automatic counting of numbers is well known in the field. This is necessary to ensure that the number of times a dose is dispensed is counted. It does not indicate to the user when the bottle is about to become empty. Not at all.

Although such dosage counters have existed for many years, the No solutions have been created for the problems in question.

Particularly regarding non-transparent aerosol containers and when such containers are ``almost empty.'' The invention therefore relates to warning of a condition in which a discharge valve is actuated. with a direct actuating connection between the handle member and the counter unit. Although it utilizes some type of known dosage counting device, However, the present invention more particularly provides for The contact-actuating connection is connected to the entire aerosol container by the standard method of actuating the discharge valve. said content such that said content is retained in said recessed portion of the tube socket within an associated retainer. This can also be avoided based on the fact that displacement with respect to the discharge valve of the The present invention is based on the recognition that

Therefore, in a highly preferred embodiment of the invention, the counter unit by that displacement of the container or more preferably by causing the container to undergo an actuating displacement. actuated by a force applied to the container to A single container has some special handle part to actuate the associated discharge valve. You shouldn't even have the materials. Therefore, as stated in claim 2, counting The container unit is added to the container by displacement of the container or by each actuation of the container. actuation of the retainer unit or container such that it is actuated by a depressing force The container discharge pipe can be connected to the container. 7. Any type of direct connection with or special actuating device 7. There is no need to provide any kind of direct connection to the

The counter unit therefore counts each degree of axial displacement of the container or The pressure exerted on the container by pressing the discharge pipe against the pipe If necessary, provide an operational connection with the retainer so that each degree of dynamic pressure is counted. It can be arranged as follows.

However, in a preferred embodiment of the invention, the count is normally It is based on a device that is actuated by finger pressure against the base. , whereby the counting unit has an operating pressure applied to the base of the container. the base part of the container so as to transmit the effect to and thereby also actuate the counting unit. The actuating member may be provided on the outside of the actuating member.

Based on this idea, it is preferable to provide the actuating member integrally with the counting unit. The counting unit configured in this way is attached to the base end of the aerosol container as a cap member. Attached to the section. Therefore, in this way, it is completely separated from the holder. When the counting unit receives actuation pressure, it counts the number of actuations. and displacement together with the aerosol container relative to the holder. do.

What type of counter end cap member should the aerosol container be equipped with? It is clear that when the airgel container is empty, it can affect the supplies placed in the holder. It is clear. The invention therefore also covers adaptations of any kind for the purposes of the invention. A supply aerosol container unit that can be used without the need for Also includes.

The counter unit of this aerosol container unit is Depending on the number of guaranteed dosages, it can be pre-adjusted.

This counter unit or member located at the proximal end of the aerosol container is , can be completely disassembled from the container, or as separate units e.g. one replaceable end cap member for each continuous use standard container; It can also be sold as a.

In general, this counter unit can be used in any suitable manner, e.g. It is constructed according to the principle that a visible signal is generated at the exact moment when the can be moved.

Preferably, however, the counters display each counter stage regularly. It should be an ordinary digital counter, so that the counter can Insofar as the number of doses inhaled by the patient can be recorded, the counter should be to track and manage.

In order that the invention may be more easily understood, the following description is made with reference to the accompanying drawings. Embodiments are described.

Referring first to FIGS. 1, 2, and 5, the illustrated medical nebulizer includes a conventional A retainer 2 from above and a conventional knee roll container 4 located within the retainer are included. There is.

The holder 2 comprises a cylindrical main part 6 into which the container 4 is tipped. It is stored by simply inserting the discharge pipe 8 into the A dose delivery valve having a diameter is received within the recessed portion 10.

This recessed portion is formed in the directly overlapping portion of the base wall 12 of the main portion.

A discharge spray nozzle 14 is connected to this recessed portion 10, and the nozzle 14 is arranged horizontally. It is surrounded by a spout 16 extending in the direction. Dispense IT dose into the neck of container 4. The medicine quantity discharge valve is provided with a discharge pipe 8 when the container is pushed downward. is controlled from the needle sol container 4 when the needle is moved towards the interior of the container. and may be operable to deliver a predetermined amount of fluid. This discharge pipe 8 has elasticity. Therefore, it is biased, but it is only necessary to do so at the base of the container. Push the container 4 downwards within the main part by applying finger pressure to the The amount of medical drug released is r! ! The nozzle 14 and the spout 16 via the J part 10. This is only to ensure that it is ejected through the . No matter how long the user keeps the container Only one dose is released, regardless of whether you hold it down or not. Served. When the finger pressure is released, the container reaches its maximum position under the spring biasing action of the discharge tube 8. It returns to its initial position, but no further ejection of medicament is caused. facing upward A counter 20 is provided adjacent to the base of the container 4 being The container has a gripping portion 22 having a lower skirt 24 that fits around the base of the container 4. , the upper part formed of a transparent material covers the lens-shaped top 28 of the actuation cap 26. Visible count columns are arranged throughout. Do not spray the spray device directly onto exposed surfaces of the container. Activate by applying finger pressure to the l/lens-shaped top 28 of the counter. be able to.

During each actuation, the counter 20 transmits the required pressure to the container while at the same time Counting containers and their associated counters have been used since the first use of the containers and their associated counters. 5 to display the number of actuations or doses administered through the lens-shaped top 28. It has become. A preferred alternative is to replace the counter unit with the When connected to the container or the entire spray device, first check the known It can be designed and adjusted to count the number of actuations inversely from the total number of doses. can.

The counter 20 can be designed based on any known counting principle, but the counter as long as a physical indication of the condition of the container can achieve the desired result. , need not be a digital display counter. This remains in the container, e.g. When the number of doses is small, a red marker appears on the top 28 of the lens shape. This can be shown by doing this.

However, the preferred construction of the counter is to use an ordinary machine with the required number of number wheels. A mechanical step counter is provided. This allows the counter to be used during the shelf life of the container. Useful for use in therapeutic management.

The structure of the counter shown in FIGS. 3 to 6 includes a grasping portion 22 and an operating cap 2. 6, the actuation cap of which includes a lens-shaped top 28 and an outwardly projecting a short cylinder having a lower end with a bevelled flange 3o; It is formed as. Inside the actuating cap 26, the actuating caps are mutually connected. It consists of a main shaft 32 supported between two opposing wall parts and a three-stage single number wheel counter. A step counter 34 is arranged. The second axis 36 has a However, the parts forming the two transmission wheels of a well-known type of counter are arranged. It is placed. The number wheel is mounted between the two end plates 38.40 and These end plates abut the inner surface of the actuation cap along their opposing edges. Supported.

The end plate 40 extends downwardly and is fitted with a vertical slot 42. The shaft 32 is provided with a slot 42 protruding through it. It is designed to allow reciprocating motion in the right direction. The lower left side of the end plate 4° (5th (see figure) is provided with a pawl 5o, which is attached to the step provided on the first number wheel. It is bent toward the first number wheel to cooperate with the ping knob 52.

In this way, the first digit wheel is set to 1 in response to each upward stroke of the end plate 4o. Count the steps.

The grasping portion 22 has a cylindrical main body 54 with an inner wall at the top end of the main body. The main body 54 is located above the top of the skirt 24 on a sloped surface that protrudes toward the It has an annular flange 58 at the bottom. Corner between flange 5 and skirt 24 A stepped portion 6o is formed at the portion.

An annular corrugated surface spring 62 is disposed between the actuation cap 26 and the grasping portion 22. The spring is connected to the top side of the annular flange 58 and the annular bottom of the actuation cap 26. It acts between surfaces.

The grasping portion 22, the actuating cap 26 and the spring 62 are pressed together together. It is easily assembled by opening the bottom of the actuating cap 26 and protruding outward from the bottom of the actuating cap 26. The flange 30, which is chamfered in the shape of an inclined surface, protrudes toward the inside of the grasping portion 22 and forms an inclined surface. These portions 2 should fit into the underside of the flange 56 which is chamfered in the shape of 2.26 and 62 will not separate after assembly. These parts 22.26 and When springs 62 and 62 are assembled together and sufficiently compressed, spring 62 is compressed. The end plate 40 is now in the closed position with the flap 46 and the annular flange 58 at the bottom of the plate. is displaced upwardly by contact between the top side of the

However, the end plate 40 has sections 22, 26 and 62 assembled together. During the final stage of being pressed down, it collides with the top part of the actuating cap 26. and is pushed downward. As a result, each other's ridgelines are downward. a flap 46 with an outer edge 48 that is beveled to converge toward Due to their shape and location, these flaps 46 also extend below the annular flange 58. The edge of the flange will be The end plate 40 is received within the notch 44 and then the end plate 40 is vertically aligned with the flange. 58 will be firmly combined. When the pressure on the actuation cap is released, Spring 62 holds the actuation key until the actuation cap engages flange 56. The cap is pushed upwards, but the end plate 40 does not participate in this. Sunawa The actuating cap will cause the counter to become ready for actuation by the following pressure applied to the actuating cap: Moved to prepare.

The assembled counter is arranged at the base of the container 4, so that it has an annular stepped shoulder. The portion 60 has a flap 46 between the end surface of the container base and the lower surface of the flange 58. Equipped with free space for storage. In this way, the flap 46 is firmly fixed. the actuating cap can therefore be rotated with respect to the gripping part 22; The user thereby selects some convenient rotational position for the digital counter. can do.

The spring 62 is slightly smaller than the spring provided for biasing the discharge tube 8 of the container 4. to make it weaker or to the same degree of strength.

The operation of the counter is clear from the above description.

The actuation cap 26 is extended to such an extent that the aerosol container delivers a single dose. When pressed down (see Figure 6), the actuating cap changes relative to the end plate 40. the counter is activated, and the activation cap is then activated. Relieving the pressure on the counter (see Figure 5) places the two counters in a prepared state for subsequent operation. Let them become like that.

FIG. 7 shows that the container holder, here designated 64, is a counter unit including a number wheel 66. 1 shows a modified spraying device with a (Although not shown) Those skilled in the art As can be easily understood, this counter has a It can be provided with an internal actuating member that is captured so that the depression of the container is counted can be rotated one step at a time.
