Definitions
- the invention relates to a medical medication dispenser.
- medication dispensers are often used, which are operated by the patient in order to supply himself with a required medication.
- Such drug dispensers can e.g. an inhalation device or injection device for example insulin or pain reliever.
- An inhalation device is known from EP 0 642 802 Bl and EP 0 814 860 Bl, in which the distribution of medicinal liquid and its optimal atomization is ensured in order to achieve a desired dose at a
- the invention is therefore based on the object of specifying a medicament dispenser which ensures the dosage of the medicament within the permissible tolerance limits during its lifetime.
- This object is achieved according to the invention by a medicament dispenser with a metering device and an indicator device which, by adding up at least one usage value, which is assigned to each actuation of the metering device, forms and displays a total usage value.
- the advantage of the medication dispenser mentioned is, in particular, that the total usage value formed according to the invention allows a conclusion to be drawn as to whether the medication dispenser is still functioning as desired and in particular continues to ensure the correct dosage of the medication.
- the medication itself is usually provided with a date which indicates the point in time until the effectiveness of the medication is guaranteed.
- the medication dispenser according to the invention now also provides additional security as to whether the device itself which is intended to deliver the medication to the patient is functioning reliably.
- the metering device and the indicator device are connected to a medicament container.
- the indicator device sums up a usage value that is assigned to each actuation of the metering device and, in addition, receives information through the connection to the medication container as to whether the accumulated usage value corresponds to the conditions in the medication container, for example the current fill level of the medication container , For example, it can be determined whether the medication container has an undesirable leak or the summed up individual usage values, each of which is a single dose of the medication lead to an overall usage value, which can be too high or too low in the event of a malfunction of the medication dispenser and thus does not correspond to the remaining amount of the medication in the medication container.
- the metering device comprises at least one motor and the indicator device is connected to this motor.
- a motor can be provided for a medication dispenser which ensures the accuracy of the medication dose applied each time the metering device is actuated.
- the time period during which the motor is running when the metering device is actuated is a measure of which dose of the medication is applied with each actuation.
- the indicator device thus sums up a usage value which corresponds to the respective running time of the motor when the metering device is actuated, and is thus a measure of the total dose of the medicament which has already been administered.
- the indicator device is advantageously connected to the motor of the metering device via a gear.
- the gearbox ensures that the movements of the motor shaft are optimally implemented for detection by the indicator device.
- the detection accuracy of the indicator device can be influenced, for example.
- the gear ratio of the transmission plays a role in the calibration of the display of the total usage value by the indicator device.
- the indicator device is capable of indicating that a minimum total usage value has been exceeded.
- a minimum total usage value can be derived, for example, from the design and construction of the medicament dispenser and e.g. of a total dose of the medicament, which can be administered in single doses with high probability during the lifespan of the medicament dispenser without a malfunction of the medicament dispenser occurring.
- the indicator means means.
- the patient receives valuable information that the functionality of his medication dispenser may no longer be possible. This enables him, for example, to have his medication dispenser inspected in good time in order to prevent an impending restriction or even a loss of its function.
- the minimum total usage value is advantageously determined in advance by means of test series.
- the respective device runtime is determined for similar drug dispensers, during which the patient with a high degree of certainty does not receive a drug dose that deviates from a desired standard value.
- the device runtimes determined for the individual drug donors tested are then processed using known statistical methods.
- a result can be, for example, a statistically determined minimum total usage value, which corresponds to a total drug dose that can be delivered with high probability by a drug dispenser of the type tested.
- a statistically determined minimum total usage value can also, for example, total running time of the motor of the metering device, during which the motor is highly likely to work faultlessly.
- the indicator device is designed as a counting device which determines the total amount of medication withdrawn and / or the entire period of use as a value in use during the operation of the medicament dispenser.
- Both mentioned embodiments of the use value are valuable indications for the patient whether his medication is still guaranteed to the desired extent; the total amount of medication withdrawn is a measure of the total medication dose given and the total period of use is a measure of how long the medication dispenser has been actively used.
- the indicator device comprises an indicator disc from which the current usage value can be read.
- the patient can conveniently read the current total usage value.
- the indicator disc is advantageously subdivided into at least two partial areas, each of which is assigned to a value or a value range of the total usage value.
- the indicator disc is subdivided into a green and a red partial area, which correspond to the states "medication dispenser functional" or "medication dispenser may no longer be fully functional". Now if the patient has the current total usage value If he reads "green” from the indicator disc, he knows that his medication dispenser is very likely to be fully functional. If he reads the total usage value "red” from the indicator disc, he knows that it is necessary to have his medication dispenser inspected. These two important pieces of information are usually sufficient for the patient; it is usually not necessary to show the total usage value in more detail.
- FIG. 1 shows a longitudinal section through a medication dispenser, which is designed as an inhalation device
- FIG. 2 shows a longitudinal section through a medication dispenser, which is designed as an injection device.
- the medicament dispenser 5 according to FIG. 1 has a metering device 7, which comprises a motor 9, a gear 11 and a metering piston 13.
- the patient triggers the delivery of a dose of the medication by actuating the actuation button 8, which is reported to the control device 30 via the sensor line 29.
- the control device 30, which is connected to the voltage supply 32, controls the motor 9 via the control line 31 in such a way that it moves a metering piston 13 in the direction R via the transmission 11, so that a desired medication dose from the medication container via the connecting line 22 into the Mouthpiece 24 is ejected.
- the motor 9 is also connected via the gear 11 to an indicator piston 15, which is part of an indicator device 16.
- control device 30 is connected to the voltage supply 32, to the sensor S of the medicament container and to the pump 10.
- the control device 30 controls the pump 10, which feeds the desired amount of the medicament, which is removed from the medicament container 20, to the injection needle 25 via the connection line 22.
- the indicator device 16 comprises an adder A, which is an advantageous component of the control device 30, and a display 18, from which the current total usage value can be read.
- summer A can form one or even two total usage values, which can be displayed on display 18.
- a first possible use value is the dose of the medication which is expelled into the injection needle 25 each time the actuation button 8 is actuated. These individual doses can be recorded in the control device 30 and processed by the summer A to the total usage value "total dose”.
- control device 30 can also use the sensor S as a usage value to add up the amount of medication withdrawn from the medication container 20 each time the actuation button 8 is actuated to form the total usage value “total medication withdrawal amount”.
- One or both of the total usage values can be displayed on the display 18 and read by the patient.
- a memory M which is advantageously contained in the control device 30, one or more minimum total use values are stored, which are compared by the control device with the corresponding or current total use values, which are formed by the summer A , Exceeds one or more current ones Total usage values or the corresponding minimum total usage values stored in the memory M, this excess is displayed to the patient on the display 18.
