Description

Microfluidic delivery device

Technical Field

The present invention relates to the field of fluid delivery for administration to a patient, and more particularly to a micro fluid delivery device for administration to a patient.

Background

Diabetes is a metabolic disease characterized by hyperglycemia. Hyperglycemia is generally caused by a defect in insulin secretion or an impaired biological action thereof, or a combination of both. The prolonged presence of hyperglycemia in diabetic patients can lead to chronic damage, dysfunction of various body organs (e.g., eyes, kidneys, heart, blood vessels, nervous system, etc.).

Clinical diagnosis of diabetes can be divided into type 1 diabetes and type 2 diabetes. Type 1 diabetes, also known as insulin dependent diabetes mellitus, is a disease that is inherited by the innate family, with the pathology of patients often occurring in childhood or adolescence. Type 1 diabetes is an autoimmune disease in which the immune system of the body attacks the beta cells that produce insulin in the body, eventually leading to the failure of insulin production in the body. Such patients require the injection of exogenous insulin to control blood glucose levels in the body. Type 1 diabetics typically require 24 hours of wear of an electronic insulin pump therapy, such as the mayonnaise Minimed series of insulin pumps. Type 2 diabetes, also known as non-insulin dependent diabetes mellitus, is commonly referred to as adult-onset diabetes, especially in obese humans, and its condition can lead to wasting. Possible causes include: insulin resistance, which makes the body unable to use insulin effectively; the decrease in insulin secretion is not satisfactory for the body. Early type 2 diabetic patients can be controlled and even cured of diabetes by improving lifestyle (e.g., healthy diet, moderate exercise, safe weight loss, smoking cessation, avoidance of second-hand smoke, etc.). Most type 2 diabetic patients can help control the body blood glucose levels by orally administering hypoglycemic agents or by phased injections of insulin.

Conventional drug infusion devices, such as patch pumps (patches) require a wireless controller (e.g., a mobile terminal such as a cell phone) to control or manage the micro-delivery during micro-fluid delivery control. That is, the conventional drug infusion device requires additional device cooperation to control or manage the micro-fluid delivery, and is inconvenient to operate.

Detailed Description

Various aspects of the invention are described in detail below with reference to the figures and the detailed description. Well-known structures, components, and their interconnection, linkage, or operation are not shown or described in detail. Also, the described components, structures, or functions may be combined in any suitable manner in one or more embodiments. It will be understood by those skilled in the art that the various embodiments described below are illustrative only and are not intended to limit the scope of the present invention. It will also be readily understood that the components, structures, units or steps of the various embodiments as described herein and illustrated in the figures can be combined and designed in a wide variety of different configurations. It will also be readily understood that although specific names, terms, ranges, etc. may be explained in only some embodiments, the explanations are equally applicable to other embodiments unless specifically noted.

The utility model provides a trace fluid delivery device is used for realizing the control of delivering of trace fluid. Taking insulin injections as an example, a case of a basal amount bolus and a bolus (also called a bolus) bolus is included, and a trace amount corresponds to a case of a bolus. Fig. 1 provides a schematic flow diagram of a microfluidic delivery control method. Referring to fig. 1, the method includes:

100: the set signal collection period is entered in response to the first operation signal.

Optionally, in an implementation manner, the first operation signal is generated by a user operating a key.

102: determining a fluid delivery amount according to the number of times the setting signal is collected during the setting signal collection period.

Optionally, in one implementation, the setting signal is generated by a user operating a key.

Optionally, in one implementation, the signal collection time period is a fixed value (e.g., in seconds). In another implementation manner, the signal collection time period is a non-fixed value, and a specific value thereof is determined by a preset maximum time interval between two adjacent setting signals and whether the setting signal is received.

104: in response to a second operation signal, a fluid delivery process is performed based on the fluid delivery amount.

Optionally, in an implementation manner, the second operation signal is generated by a user operating a key.

With the present method, compared to the prior art, the delivery control of a minute amount of fluid (e.g., a medicament) can be achieved without the involvement of a wireless controller (e.g., a cell phone or a dedicated control device), which is convenient for the user to operate and use.

Optionally, in an implementation, the process 102 is implemented by: monitoring the setting signal within a set time of entering the setting signal collection time period; updating the number of times the setting signal is collected or updating the fluid delivery amount if the setting signal is monitored; if the set signal is not heard, determining not to perform the fluid delivery process.

In the process 102, or in the foregoing implementation, the setting signal is monitored continuously for a set time after each monitoring of the setting signal; updating the number of times the setting signal is collected or updating the fluid delivery amount if the setting signal continues to be monitored. Further, if the set signal is not continuously monitored, a reminder is fed back indicating the fluid delivery amount. For example, the reminder is fed back through a vibration module, a sound module, a light module, and the like.

Optionally, in one implementation, the setting signal indicates an accumulation of a preset amount of fluid delivery. The preset amount is an editable value, and is set according to the dosage required by each meal and the personal medicine taking habit.

Optionally, in an implementation manner, the first operation signal, the setting signal, and the second operation signal input by a user through the same key are received. The same key can be a physical key, a touch key, a virtual key and the like. For example, the first operation signal is generated when the user presses a physical key for a long time, the setting signal is generated when the user presses the physical key within a set time period, and the second operation signal is generated when the user quickly double-clicks the physical key. Of course, the skilled person can flexibly set the corresponding relationship between the operation mode of the same key and the generated signal according to the idea provided by the implementation mode.

By adopting the implementation mode, the control method provided by the implementation mode can be realized only by arranging one key, and the control method is simple in structure and convenient to operate.

Optionally, in an implementation manner, in response to the received first operation signal, the setting signal, or the second operation signal, a reminder indicating that a signal is received is fed back. For example, the reminder is fed back by a vibration module, a light module or a sound module. By adopting the implementation mode, the interaction with the user can be realized, and the prompt is provided for the user operation, so that the accuracy of the user operation is improved.

The fluid delivery process in process 104 is conventional and the specific process is not limited by this application. Illustratively, the fluid delivery process may include: detecting whether the consumable is dropped off or blocked; executing pesticide spraying; a vibration alarm or the like is performed when there is a non-emergency alarm message.

Fig. 2 shows a process schematic of one fluid delivery method. Referring to fig. 2, the method includes the following processes:

200: the button is turned on (i.e., turns on the fluid delivery device).

201: and detecting whether the consumable is installed and waiting for the connection of the controller. The controller refers to the existing control equipment, mobile phones, tablets and the like special for fluid infusion.

202: and judging whether the controller is connected, and if the controller is connected, carrying out fluid delivery processing according to the received large-dose pesticide spraying command parameter and/or basic-dose pesticide spraying command parameter if the data sent by the controller is received. Without the controller connected, if a long key occurs within the wait time (the wait time, the key time of the long key may be flexibly set as required, not limited herein), a bolus dose bolus setting and a fluid delivery process are performed; if the waiting time is exceeded without the occurrence of a long key, the subsequent processing 207 is executed after the waiting time is exceeded.

Wherein the bolus dose administration setting comprises:

203: and executing board vibration feedback after the long key and entering a BOLUS setting mode.

204: judging whether a key is pressed, if yes, executing 205; if no key press is made for more than 5 seconds (which time is customizable), then 206 is performed.

205: the BOLUS dosing amount is increased by one (i.e., by a preset amount) and plate vibration feedback is performed once.

206: and judging whether the BOLUS dosage is set. If not, execute 207; otherwise 208 is performed.

207: and clearing the set BOLUS dosage and exiting the BOLUS setting.

208: and (4) finishing the setting of the BOLUS dosage, and executing the corresponding vibration times of the plate driving motor.

209: and judging whether the key is pressed within 5 seconds (the time can be defined by user). If so, then 210 and subsequent steps are performed; otherwise 207 is performed.

Wherein the fluid delivery process comprises:

210: and judging whether the pesticide spraying condition is met. Specifically, 210 may include: detecting whether the consumable is dropped or blocked or exceeds the maximum daily total amount or completing the drug injection. If the pesticide spraying condition is not met, executing 211 and subsequent processing; if the laxative condition is satisfied, then 215 and subsequent processing is performed.

211: and performing plate vibration alarm.

212: stopping the pesticide spraying.

213: and judging whether the controller is connected, if so, executing 214, otherwise, ending the process.

214: upload a message (e.g., upload a reason to the controller that the medication dispensing condition was not met).

215: and (5) executing pesticide spraying.

216: and judging whether non-emergency alarm information exists, such as battery power is lower than a set value, insulin is about to be exhausted, and the like. If there is non-emergency alert information, 217 and subsequent processing are performed, otherwise 210 is performed.

217: and performing plate vibration alarm.

The above shows an example of combining the medication dispensing process performed with the existing controller connected and the bolus medication dispensing process performed without the existing controller connected. The method is favorable for realizing perfect drug administration treatment.
