Description

[Detailed description of the invention] (b) Industrial application field The present invention relates to an ejection device for powder medicine packaging.

(b) Conventional technology Conventionally, dividing and packaging powdered medicines was carried out as follows.

That is, several types of required powder medicines are measured and taken out according to the prescription from a variety of medicine bottles stored on a powder medicine dispensing table, and then these are placed in a mortar or mixer and mixed.

Then, this admixture is divided and packaged using a dividing and packaging machine.

Such divisional packaging machines can be broadly classified into one-type hopper type and V-valve type.The one-hopper type uses a rotating disk having a predetermined number of drug distribution holes on the periphery below the hopper into which the admixture is to be introduced. A hopper containing the admixture is vibrated by a vibrator to discharge the admixture downward and a rotating disc is rotated. The release admixture is configured so that it is evenly distributed into the drug distribution holes of the rotary disk, and furthermore, the bottom plate of the distribution hole is configured to be openable and closable, so that the same two drugs are distributed evenly.
- The admixture in the distribution hole is individually discharged and dropped into the packaging device so that a predetermined number of sachets are packed in the same packaging.

In addition, in the V11 method, a square with a substantially V-shaped cross section is formed into a ring shape by an inclined inner wall and an outer wall, and the inner wall can be raised and lowered freely. A drug release gap is formed between the lower end of the wall and the lower end of the inner wall, and a rotary disk is disposed below the rotating disk for forming the drug distribution hole, and a packaging device is disposed below the rotary disk. This is Shino who is setting it up.

Then, pour the admixture into the V-cell and level the top surface, and climb up the inner wall in the same state. The admixture is then dropped into the drug distribution hole of the rotating disk, and the bottom plate of the distribution hole is opened to perform packaging using the packaging device.

As described above, in the conventional powder medicine dividing and packaging operation, an admixture is manually prepared and then divided and packaged by a machine.

(c) Problem that the invention seeks to solve = 3
- However, in the above-mentioned dividing and packaging work for powdered medicines, the following problems occur:

In other words, it is caused by the adhesive properties of powdered medicines, and -
There are contamination, division errors, mixing errors, etc. Contamination is a problem in which powders that have been previously dispensed or divided and packaged remain, and the previous powders are mixed into the powder that is subsequently dispensed or divided and packaged. be.

In addition, division errors include the problem that the weight of the admixture weighed and dispensed in advance does not match the sum of the weights of the admixture packaged, and the problem that each individual package Kiffi ends up being different. It is.

The name of the song is due to the fact that the powder is gradually deposited in places such as hoppers where a large amount of powder is deposited, or in a complicated mechanical distribution process. The amount of division and even the amount of packaging are different.

In addition, mixing errors are a problem in which the mixing ratios of each powder in each final package are not uniform.

-4= This is especially likely to occur when the powder is mixed in slightly, and because the mixing is not uniform, there is a problem that the powder is not mixed in some sachets. It is.

The above problems are serious and serious in that uniformity of drug efficacy cannot be expected.

In addition to the above, there are other problems with chemical dust. This happens when medicines are dispersed into the air when dispensing work is done manually.The ToffA machine is used to manage the health of the dispensing room and to improve environmental hygiene in several ways, but it is not sufficiently effective. There is no.

Furthermore, there is a problem in that the dispensing room must be made larger due to the need to introduce large equipment such as a dispensing table and a dividing/packaging machine.

In addition, it takes at least 20 to 30 minutes from dispensing to dividing and packaging.
Moreover, it requires a large amount of labor costs, increases waiting time for patients, and increases the number of drugs left. This is causing the problem of increasing numbers of people.

−5= There is also the problem that drug inventory management is cumbersome.

(d) Means for solving the problem Therefore, in the present invention, a rod is inserted into a tubular nozzle body having a powder jetting passage at the lower end so as to be able to slide forward and backward intermittently, and the lower end of the rod is inserted into the tubular nozzle body. The ejection passage is configured so that it can be repeatedly opened and closed, and a separate powder introduction pipe is branched into the hollow part of the nozzle body, and the powder introduced into the hollow part of the nozzle body through the introduction pipe is passed through the ejection passage. It is an object of the present invention to provide a dispensing device for dispensing powders which is capable of intermittently dispensing dispensing by opening and closing a rod.

(B) Function When packaging powder medicine, the powder is introduced into the nozzle body from the powder introduction tube, and the rod is slid up and down, and the lower end of the rod connects to the powder jet provided at the lower end of the nozzle body. By opening and closing the passage, a certain amount of powder is ejected into the area where the passage is opened.

Furthermore, the diameter of the Df-th 11th path and [lrad vertical movement 1
By adjusting the habitual stroke appropriately, the darkness of the powder ejected at - times can be freely adjusted and covered, and the amount of powder ejected can also be set by the number of times the powder ejection channel is opened and closed. It is something.

Therefore, if each type of powder is taken out from each ejector for each ejector for sachets, a predetermined amount of each powder of different types can be taken out from each ejector, mixed, and then packaged. It is something that can be covered.

(to) Effect East According to the present invention, the following effects can be achieved.

In other words, problems such as contamination, division errors, and mixing errors can be solved all at once since the appropriate amount of each type of powder can be jetted individually from the powder packaging jetting device. .

Moreover, since the packaging operation can be performed by remote control while each ejection device is housed in a predetermined case, problems such as space for medicine and mechanical equipment can be reliably solved.

Furthermore, since packaging operations can be performed quickly and accurately, personnel costs can be reduced, the number of drugs left behind can be reduced, and drug inventory management can be facilitated.

Furthermore, since the ejection device for dispensing powdered medicines according to the present invention can be automatically controlled by a pump coater, it is possible to simultaneously solve the conventional concerns of streamlining the dispensing process and ensuring drug efficacy. It is.

(G) Example An example of the present invention will be described in detail based on the drawings. Fig. 1 shows an ejection device (A) for dispensing powdered medicines, and the ejection device (A) is an air cylinder (1). and the nozzle body (2

) (1d) is the air piping.

The nozzle body (2) is formed by connecting an upper tube (4), a middle tube (5), and a lower tube (6) detachably in the vertical direction.

The upper pipe (4) has a bottom end communicating with 1", and has frontage windows (4a > (4a) on the left and right sides of the middle part, and the lower end opening (4b) has a rod (3).
) is formed to have a slightly larger diameter.

(4C) is a female thread formed on the inner circumferential surface of the upper end opening, which is screwed onto the lower end of the cylinder main body (1a) of the air cylinder (1), and (4d) is the female thread formed on the inner peripheral surface of the upper end opening. This is a male threaded part formed on the outer periphery of a small diameter part with the same step formed in the part. (4e) is an air vent hole provided at the top of the upper tube (4).

The middle pipe (5) is formed with a communicating opening at the upper and lower ends, and
The male threaded part (4d) of the upper tube (4) is attached to the inner peripheral surface of the L end opening.
The lower end opening (5b) is formed to have the same diameter as the lower end opening (4b) of the upper tube, and the lower end opening (5b) of the upper tube A 1-threaded portion (5C) is formed on the outer periphery of the stepped small diameter portion.

Therefore, when the upper pipe (4) and the middle pipe (5) are screwed together, the lower end opening (4b) of the L part pipe (4) and the lower end of the middle pipe (5), which have the same diameter, A large diameter cylindrical space (S) is located between the opening (5b) and the middle pipe (5).
This will be formed within the main body.

In the figure, (5d) is an air vent hole.

The lower pipe (6) is formed hollow with an opening at the upper end, and
A female threaded portion (6a) is formed on the inner circumferential surface of the upper end opening so that a threaded connection to the middle pipe (5) can be made via the spaced threaded portion (6a), and the lower pipe (6) An inverted circular 61 [surface (6b) is formed at the lower end of the inner peripheral surface of the hollow part (6d), and powder medicine is formed between the lower end of the inverted conical surface (6b) and the lower end surface of the lower tube (6). A jetting passage (6c) is formed.

The powder ejection path (6c) has a path length (d
) is held 1゛, and the same rod - approximately the same as (3) -
The diameter is 10 mm, but the 10-inch (3) is formed to be slidable.

In addition, a powder introduction pipe (7) is connected in an inclined manner to the middle part of the hollow part (6d) of the lower pipe (6).
) and the center line of the lower tube (6).
) is configured to intersect within the inverted conical surface (6b) formed at the lower end position of the inverted circular conical surface (6b), and the powder (B) introduced along the inverted circular e+1 surface (introduction = 11 - tube (7))
6b).

The material of the nozzle body (2) configured as described above is not limited to metal, and may be any material such as ceramic, synthetic resin, etc.

Next, the rod (3) inserted into the nozzle body (2)
I will explain in detail.

That is, the rod (3) is formed by forming a rod body (3a) in the shape of a vertically elongated rod, and connecting the upper end of the rod body (3a) with a large-diameter tube (3b) fitted into the lower end, so that the rod body (3a) can move forward and backward. There is an air inflow channel (3C) in the longitudinal direction from the upper end to the lower position.
), and the upper end of the inflow channel (3C) is connected to a large diameter pipe (3b).
The large diameter pipe (3b) is connected to the inside and communicated with the air inflow pipe (3d) bored at the bottom of the same large diameter pipe (3b), and the lower end of the air inflow path (3C) is provided with air jet holes (3
e) (3e) (3e) is bored so that the compressed air fed under pressure from the inflow pipe (3d) passes through the air inflow path (3C) and is ejected from the 1-ar jet hole (3e). are doing.

= 12 - Moreover, the air jet hole (3e) is always connected to the powder introduction pipe (7) even when the rod (3) is moving back and forth up and down.
The powder medicine (B) introduced at the same position can be dispersed by compressed air.

The rod body (3a) has a length such that when the rod (3) is advanced to the lowest position, the F end becomes an open end in the powder jetting path (6c) or slightly protrudes. Moreover, two grooves (3f) are formed on the inner circumferential surface of the lower end of the rod body (3a) which slides in the same jetting passage (6c).
(3f) and powder medicine (3f) in the groove (3f).
B) accumulates, and this accumulated powder exerts a packing effect between the inner circumferential surface of the powder ejection passage (6c), so that the powder (B) is unnecessarily ejected to the outside from the same ejection passage (6c). It is something that can never be done.

The large diameter pipe (3b) is formed to have a diameter that allows it to slide vertically inside the upper pipe (4), and has a female threaded portion (3b) on the inner peripheral surface of the upper end opening.
9), and connect the piston rod (1) of the air cylinder (1) through the spaced threaded part (3Q)-13
b) The tip is designed to be screwed 1, and the same large diameter pipe (3b)
A compressed air inflow vibrator (3h) is connected to the air inflow pipe (3d) provided in the upper pipe (4) through the opening window (4a) of the upper pipe (4).

The injection device for powder medicine packaging (A> is made by screwing the upper end of the rod (3) onto the tip of the piston rod (1b) of the air cylinder (1) configured as described above, and attaching the rod (3) to the nozzle body (2). ) from above and insert the same cylinder (
1) Connect the lower end of the cylinder body (1a) to the nozzle body (2)
Once the top end is connected, the assembly work is completed, and when packaging powder medicines (B), it is only necessary to install the same ejection device (A) for each powder medicine as shown below. .

(See Figure 6) J, that is, connect the air cylinder (1) to the air pipe <1d
> (1d) to the air source, and also connect the compressed air inflow pipe (3h), which is connected to the rod (3), to the air source, and connect the cylinder (1d) to the air source.
) so that compressed air from the same pipe (3h) is ejected from the air ejection hole (3e) at the moment the rod (3) descends to open and close the powder ejection passage (6c), and
The powder medicine introduction tube (7) stores the powder medicine (B)].
The same unit is connected to the case (C) and pressurized]~
The powder (B) in the ivy case (C) is the F rod (3)
As the temperature rises, the lower pipe (6) of the nozzle body (2) is transferred from the powder medicine introduction pipe (7) through the powder medicine introduction pipe (8).
It is sufficient if the material is fed under pressure.

At this time, the atmospheric pressure is set to 1, and the compressed air inflow pipe (3
h) Increase the pressure of the compressed air that flows in intermittently to 1.3~
1.6, and if the pressure applied intermittently in the stock case (C) is set to 1.2, the powder (B) that is being fed under pressure
Compared to this, when the rod (3) rises, the residual compressed air in the compressed air inlet pipe (3h) is jetted out from the air jet hole (3e) of the rod (3) with higher pressure. As a result, the powder (B) introduced into the nozzle body (2) is scattered in a blow-up shape, and the powder (B) is also sprayed into the nozzle body (2)
The powder (B) flowing and staying below e) is ejected in a fixed amount from the open powder ejection path (6c).

Therefore, if the rod (3) repeats the upward and downward reciprocating movement of the rod (3) as described above, the powder (B) that has been thrown up in advance will be ejected one after another, so the powder (B) will be ejected in a combined state. In addition, a fixed amount of powder can be ejected intermittently and accurately in response to the movement of the rod (3).

Furthermore, if you use the ejection device ff (A) for powdered medicine packaging, you can even eject a minute amount of powdered medicine, such as around 0.2e, using a non-contact switch (
This is possible by adjusting the stroke of the rod (3) through the rod (1C), so that the degree of miscibility with other powders can be ensured. > (3f) The packing effect caused by the powder (B) retained in (3f) is greatly effective.

Also, if you adjust the position of the air jet hole (3e) and the jet timing of compressed air as appropriate depending on the type of powder,
It is possible to eject a predetermined amount of powder in various ways.

Therefore, the packaging operation is carried out by disposing a mobile packaging device (D) below the jetting device (A) that jets out the required powder, and by moving the device (D). Spout 11 (A
) Take out the required amount from 1. l: The process ends once the powdered medicine is packaged.

In the packaging device (D> shown in FIG. 6), (D-1) is roll paper, (D-2) is a sealing part, (D-3) is a paper feed roller, (D-4) is a cutter, ( D-5) is a moving screw, and (D-6) is a motor. (E) is a weighing instrument.

In addition, when the powder (B) thrown up inside the nozzle body (2) moves upward, the cylindrical space (S) of the middle pipe (5)
The powder is suppressed from entering the upper tube (4), and furthermore, the powder is released to the outside from the rectangular opening window (7Ia) of the upper tube (4), and the powder is contained in the air cylinder (1). B"
) to ensure that problems such as intrusion can be prevented.

In addition, the above-mentioned powder medicine dispensing ejection device (A), sudock case (C), dispensing packaging container D), and weighing instrument (E) are encased in a predetermined case, and each device is accessed from the outside. If it can be operated, problems such as chemical dust and space can be solved.

Furthermore, if the above-mentioned devices are operated under computer control, quick and reliable packaging operations and inventory management of powdered medicines can be performed.
