METERING DEVICE

Abstract

A metering device for a drinking vessel for dispensing a liquid from the drinking vessel, with a control device which detects and/or controls the delivery of the liquid. Furthermore, the invention relates to a drinking bottle having such a metering device. The drinking bottle is particularly suitable for administering a Levodopa suspension for the high-frequency treatment of idiopathic Parkinson's disease.

Description

[0031] The invention is explained in more detail below using a preferred exemplary embodiment. There is shown in

[0032] FIG. 1 a drinking vessel in a side view,

[0033] FIG. 2 a closing device in a side view

[0034] FIG. 3 a closing device with a stirrer and

[0035] FIG. 4 a locking device with a control panel in a top view.

[0036] The drinking vessel 8 according to FIG. 1 has a drinking receptacle 2 which forms the vessel body. The drinking receptacle 2 has a cylindrical shape with a vessel neck 14 to which an eyelet 15 is attached for attaching a strap, not shown. The drinking receptacle 2 is made of plastic, for example polyethylene terephthalate (PET). As described above, however, other materials can also be considered, depending on whether the drinking receptacle 2 is a disposable or reusable drinking vessel or whether the drinking receptacle 2 should be collapsible. The drinking receptacle 2 is single-walled. However, it can also be double-walled in order to keep the temperature of the liquid as constant as possible. The wall 16 of the drinking receptacle 2 is here provided with a light protection coating 17. It has a viewing window 11 extending over the length of the drinking receptacle 2 with a display device in the form of a scale 12 in order to be able to control the filling level of the drinking receptacle 2.

[0037] The closing device 9 is designed in the form of a screw element and closes the drinking receptacle 2. It is provided with a drinking nozzle via which the liquid 3 can be dispensed. The drinking nozzle 18 can also be provided with a mouthpiece.

[0038] The control device 4 and the storage chamber 5 are located inside the closing device 9. In addition, the entire sensor system, tubing for the liquid 3, valves and devices for power supply are arranged in the closing device 9.

[0039] In FIG. 2, a closing device 9 is shown in a side view. A valve 18 controllable by the control device 4 blocks the tubing 19 for the liquid 3. In addition, a sensor 6 is provided in the form of a flow sensor, which is also connected to the control device 4.

[0040] FIG. 3 shows a closing device 9 with agitator 10. The agitator 10 is driven by an electric motor 20 and is designed with an agitator shaft 21 on which agitator elements 22 are arranged. The agitator 10 can also be connected to the control device 4.

[0041] The closing device 9 according to FIG. 4 shows the control panel 7, which has a display 23 for displaying the relevant setting parameters such as metering volume, metering times and the like. In addition, controls for example in the form of buttons 24, 25 and optical display elements in the form of LEDs 26, 27 are provided.

Example of a Use of the Drinking Vessel

[0042] The use of the drinking vessel 8 according to the invention is explained below for the administration of a levodopa suspension for the high-frequency treatment of idiopathic Parkinson's disease.

[0043] A 500 ml drinking receptacle 2 is filled with 500 ml of a levodopa/carbidopa suspension (e.g. 1000 mg levodopa/250 mg carbidopa in 500 ml SyrSpend®=2 mg levodopa/ml). The volume and time parameters for the liquid 3 to be dispensed are then set in accordance with the medical prescription via a smart phone app or the control panel 7. So that the user cannot change the medically determined intake schedule without medical consent, a lock code can be set up here that the programming system unlocks for changes after correct code entry. For example, the following parameters are entered:

[0044] 1. dose at 8:00 AM: 20-30 ml=40-60 mg L-Dopa as a starting dose

[0045] 2.-14. dose every hour from 9 AM: 10-15 ml=20-30 mg per hour as a repetitive dose

[0046] 15.-16. dose if required: 10-15 ml to e.g. max. 3 additional times a day

[0047] The patient is reminded to take the drug via the control panel 7 of the dosing device 1 and/or via a smart phone app. At the same time, a message can be sent to the treating doctor or the nursing staff, for example in a nursing facility. The control device 4 of the dosing device 1 then releases the set volume of the liquid 3, the levodopa suspension, at the predetermined time. In other words, the set volume is dispensed via the dosing device 1 and is available to the patient. If the medication provided is not taken, a further notification will be sent to the doctor or nursing staff. On the other hand, in the event of an additional required dose, the patient can make his own entry and call up the required dose. Since all medication administered can be recorded in this way, a therapy protocol can be created and evaluations carried out without great effort.
