[0001] MANUAL INSULIN PUMP CONFIGURATION

[0002] Technical Field

[0003] The invention relates to a manual insulin pump configuration.

[0004] The invention particularly relates to a manually controlled manual insulin pump configuration suitable for use by diabetic individuals who have to inject with an insulin pen before each meal or high blood sugar correction dose.

[0005] Background of the Invention

[0006] An insulin pump is a small device that delivers insulin to the fatty layer (subcutaneous tissue) just under the skin. Since an insulin pump remains attached to the body, it is known as a device that allows the user to change the amount of insulin they receive at any time of day by pressing a few buttons, or to program a higher or lower daily insulin dose, delivery rate at any time of day.

[0007] The insulin pump in the current art consists of a main pump unit that typically houses an insulin reservoir that holds between 176 and 300 units of insulin. The reservoir is connected to a long, thin piece of tubing with a needle or cannula at one end. The tubing and the end are called infusion sets.

[0008] Insulin pumps are small, computerized devices that contain an artificial pancreas that mimics the way the human pancreas works by continuously delivering small doses of short-acting insulin. The device is also used to deliver variable amounts of insulin when eating. Basal insulin rates are usually set on your pump in conjunction with your doctor, and one or more basal insulins can be programmed into your pump according to your needs. We can program the amount of mealtime insulin directly on the pump. Most pumps come with built-in calculators to help you determine how much insulin you need at mealtime based on your glucose levels and the amount of carbohydrates you have eaten.

[0009] Current insulin pumps contain expensive hardware such as Bluetooth, motors, batteries, and chipsets. These pumps connect to CGM devices that provide blood sugar data and automatically adjust the insulin rate to be administered. However, all this software and hardware makes the pump very expensive to reach.

[0010] The use of the cheapest insulin pens has two major disadvantages.

[0011] It is necessary to inject before every main meal and / or snack every day, which can be up to 10 injections per day with high blood sugar correction doses.

[0012] Insulin needles are not resistant to heat and therefore must be kept in a cool place at all times.

[0013] In the literature, the US patent application numbered US2013123709 describes the subject as “Disclosed is a drug infusion system comprising a drug infusion device having a reservoir, a window for viewing the contents of the reservoir, a cannula arranged to be deployed beneath the skin of a patient, and an actuator configured to be manually actuated to drive a medicament from the reservoir to the cannula. The system also has a cannula cover and a needle handle that holds a needle for insertion into the patient. The cannula cover and needle handle are detachably attached to the drug infusion device, and each is attachable to the other. The device further comprises a septum and a septum pincher to seal the device. The device also comprises a pumping mechanism, part of which are a last-dose lock-out mechanism and an occlusion detection mechanism, both of which operate on the same actuator.”

[0014] The aforementioned application discloses a device that allows for convenient and safe self-administration of liquid medications by a patient.

[0015] Again in the literature, in the US patent application numbered US2009088693, the following statements are included regarding the subject: "A disposable infusion device comprises a reservoir that holds a liquid medicament, a pump that displaces the liquid medicament from the reservoir to the patient, at least one valve that conducts the displaced medicament from the reservoir, and a fluid conduit that conducts the medicament from the reservoir, to the pump, and to the patient. The device includes a layered structure that defines the reservoir, pump, valve, and fluid conduit."

[0016] In the application mentioned, a device is disclosed that allows a patient to selfadminister liquid medications comfortably and safely.

[0017] Again, in the literature, in the patent application numbered US8246581 , the following statements are included regarding the subject: “A wearable infusion device comprises a reservoir that holds a liquid medicament, an outlet port that delivers the liquid medicament to a patient, a pump that holds a volume of the liquid medicament received from the reservoir and displaces substantially all of the volume of the liquid medicament when actuated, and at least a first valve, a second valve, and a third valve. The valves establish fluid connection between the reservoir and the pump when in a first valve configuration and establish fluid connection between the pump and the outlet when in a second valve configuration. At least two of the valves isolate the outlet from the reservoir when the valves are in the first valve configuration.”

[0018] In the application mentioned, a drug infusion device containing three valves is disclosed.

[0019] For the reasons mentioned above, a manual insulin pump configuration was needed.

[0020] Purpose of the Invention

[0021] Based on this position of the technique, the purpose of the invention is to present a manual insulin pump configuration that eliminates the existing disadvantages.

[0022] Another purpose of the invention is to create a structure that contains the insulin needed for at least 3 days in its reservoir. Another purpose of the invention is to create a structure that eliminates the need to carry an insulin pen with you all the time.

[0023] Another purpose of the invention is to present a structure that puts an end to the pain of needles for users.

[0024] Another purpose of the invention is to present a structure that is very low cost compared to automatic pumps.

[0025] Another purpose of the invention is to present a structure that is not visible under clothes thanks to its thin and light design.

[0026] Another purpose of the invention is to present a structure that includes the working principle and comfort of the insulin pen and the functionality of the pump to save from multiple needles.

[0027] Another purpose of the invention is to present a structure that is cheap since it does not have any electronic components but saves the diabetic individual from at least 12 needles since it provides a minimum of 3 days of use like a pump.

[0043] Detailed Description of the Invention

[0044] In this detailed explanation, the innovation in question is explained only with examples that will not create any limiting effect on the better understanding of the subject.

[0045] The invention is a manual insulin pump configuration that is controlled manually for use by diabetic individuals who have to inject with an insulin pen before each meal or for high blood sugar correction doses, and it is characterized that; comprises a reservoir (1) that contains a minimum of 2 ml of insulin in its chamber, a dose adjustment lever (2) that is positioned as a lever that adjusts how many units of insulin will be given and allows the user to manually administer insulin, a flexible cannula (5) that enters the body and enables the insulin to be delivered under the skin, a screw piston (7) that is formed as a lever that pushes the insulin in the said reservoir (1) to the cannula (5), and dose notification wheels (11) that make a click sound for each unit and prevent the dose adjustment lever (2) from returning.

[0046] Figure - 1 shows a top-down view of the manual insulin pump configuration that is the subject of the invention.

[0047] Figure - 2 shows a bottom-down view of the manual insulin pump configuration that is the subject of the invention.

[0048] The manual insulin pump configuration which is the subject of the invention consists main parts of; a reservoir (1) that contains a minimum of 2 ml of insulin in its chamber, a dose adjustment lever (2) that is positioned as a lever that adjusts how many units of insulin will be given and allows the user to manually administer insulin, a safety lock (3) that prevents the dose adjustment lever (2) from sending units by turning it unintentionally, a transparent dose indicator (4) that is positioned as a transparent cover that shows how many units will be given and how many units are left in the reservoir, a flexible cannula (5) that enters the body and enables the insulin to be delivered under the skin, an adhesive (6) that sticks to the body and prevents the said manual insulin pump configuration from moving or falling, a screw piston (7) that is formed as a lever that pushes the insulin in the said reservoir (1) to the cannula (5), an insulin loading piston (8) with a hole opened to fill the pump reservoir (1) with insulin with a syringe, the lower box (9) and the upper box (10) that consist of two parts as the protective main body, dose notification wheels (11) that make a click sound for each unit and prevent the dose adjustment lever (2), fixing bridges (12) that fix the screw piston (7) on the lower box (9).

[0049] The invention is created as a hybrid structure that combines the working principle and comfort of the classic insulin pen with the multiple needle-free functionality of the automatic pump.

[0050] The user turns the dose adjustment lever (2) to inject the insulin he needs before each meal or when a high sugar correction dose is needed, through the cannula (5) located on the manual insulin pump structure fixed to the body with adhesive (6), and ensures that one unit of insulin is pushed from the reservoir (1) by means of the screw piston (7) and reaches the cannula (5) and is injected.

[0051] The said dose adjustment lever (2) is turned once for each unit. The said dose notification wheels (11) inform the user by making a clicking sound and prevent the dose adjustment lever (2) from turning back.

[0052] The user can see how many units he has used and how many units of insulin are left in the said reservoir (1) via the transparent dose indicator (4).

[0053] In addition, a safety lock (3) is positioned in order to prevent the unintentional rotation of the said dose adjustment lever (2) and unwanted unit transfer. The main body is formed by the lower box (9) and the upper box (10). The dose adjustment lever (2), dose notification wheels (11) and screw piston (7) are fixed to the lower body (9) via fixing bridges (12).

[0054] The reservoir (1) comes empty and during the first use, the user can fill the insulin via the insulin loading pistpn (8) in the form of a hole using a syringe. Since the manual insulin pump is disposable, when the insulin in the reservoir (1) is finished, the dose adjustment lever (2) is locked, and the manual insulin pump is out of use.

[0055] Thus, the user can use a much cheaper product in a much more practical way.
