The present invention pertains to an always unified real-time system for reducing and preventing pain during testing analyte levels in a fluid sample, e.g., glucose levels in blood, modules, devices and methods thereof.
The quantitative determination of analytes in body fluids is of great importance in the diagnoses and maintenance of certain physiological abnormalities. For example, lactate, cholesterol, and bilirubin should be monitored in certain individuals. In particular, determining glucose in body fluids is important to diabetic individuals who must frequently check the glucose level in their body fluids to regulate the glucose intake in their diets. This is because diabetes can lead to serious complications if glucose levels are not well-regulated, including cardiovascular diseases, nerve damage, and kidney issues. Generally, each test involves cartridges that contain a number of test sensors used to allow users to carry multiple strips around within a single-housing object. The multiple stages required to perform such tests can be long and difficult. In some cases, once the testing package is opened, the user needs to be sure that the sensor is not damaged or contaminated as it is being placed into a sensor holder and used to test the blood sample. Further, once the sensor is placed in the sensor holder, a fluid sample must be collected and applied to the sensor More than 34M American have diabetes (2022), and more than 88M have prediabetes. Day by day, some 4,110 new people in the US are diagnosed with diabetes. Diabetes is characterized by short, medium-and long-term relevant diseases, including amputation (some 256 new cases per day) and end-stage kidney diseases (159 new cases a day). hence, annual costs of diagnosed diabetes in the US is huge, namely about $327B.
Fear of injections is estimated to affect a majority of younger children; the percentage of those fearing injections decreases to 20%-50% in adolescents and 20%-40% in young adults, sec McLenon, J., & Rogers, M. A. (2019). The fear of needles: A systematic review and meta-analysis. Journal of advanced nursing, 75 (1), 30-42. Some 32% of caregivers reported fear of injections in their child diagnosed with diabetes aged 6-17 years old, see Cemeroglu, A. P., et al. “Comparison of the Expectation of Caregivers and Children with Type 1 Diabetes Mellitus Doe Independence in Diabetes Care-Related Tasks.” Endocrine Practice 20.7 (2014): 629-637. Fear is not always significantly lower in adults: Needle fear exists on a continuum of severity from dislike and discomfort to phobia. In the general adult population, the prevalence of injection fear was found to be 16.1% in the Netherlands. The frequency of needle phobia in general adult populations is not less common. Experts estimate that needle-fear occurred in 16% of adult patients, 27% of hospital employees, 18% of workers at long-term care facilities and 8% of healthcare workers at hospitals, see McLenon, J., and M AM Rogers. “The fear of needles: A systematic review and meta-analysis.” Journal of advanced nursing 75.1 (2019): 30-42.
Commercially available glucometers are provided useful for indicating the disease, yet not for avoiding the condition while it is only a metabolic deviation. It is a hence a long felt need to have a small and portable, ready-to-use, inexpensive, without the burden to “keep and carry” it, incorporating pain reduction or prevention apparatus, suitable as a single-use, disposable system, for testing the level of glucose in the blood, characterized by both: (i) non-tedious and intuitively-operated, free of pain and anxiety for pain or discomfort, and (ii) improved user experience hence compliance for the test. This new type of glucometer encourages most of the population, the so-called ‘healthy people’, namely those who have had none previous indications for the disease, to test their glucose levels periodically, and hence enable early detection of glucose metabolism deviation and avoidance of a diabetic state.
Generally, the invention concerns devices and methods thereof for reducing and preventing pain during body fluid sampling, such as blood collection. By incorporating pain reduction/prevention apparatus, such as clamping mechanisms or ergonomically contoured elastic rigid finger-pads, these devices aim to enhance patient comfort and minimize discomfort. The methods leverage careful site selection and real-time monitoring to optimize the sampling process, ensuring both efficiency and a gentler experience. This approach not only alleviates anxiety associated with fluid sampling but also promotes better compliance and cooperation from patients, ultimately improving overall healthcare experiences.

The integrated diagnostic device for analyzing a fluid sample of the present disclosure, and its variations, is novel and inventive by enabling several significant features not provided by any reasonable understanding of the prior art or combination thereof. Firstly, the device includes a clamping mechanism which is configured to immobilize a finger, such that it is fixated firmly between an immobilizer and finger padding components. The clamping mechanism is configured to apply a clamping force on a finger to be sampled, thereby creating a “bubble” in the finger pad of the immobilized finger. The “bubble” to be pierced is provided in a tension so that it is held firmly and the skin is thin as possible, thus reducing pain when pierced by the retractable lancet. The tension is also effective to increase blood pressure in at least 5 mmHg as compared to local blood pressure before tensioning the upper pad of the finger and said bubble. Secondly, the lancet mechanism is not user-dependent, but rather executed by a predefined spring mechanism, with constant speed, velocity and retractable stages. The spring-dependent lancet mechanism allows for a one-time sampling event and prevents the necessity of resampling.
The clamping mechanism plays a critical role in ensuring accurate, consistent, and efficient blood sample collection in the integrated diagnostic device. Its primary purpose is to stabilize the finger during the sampling process and create the optimal conditions for blood extraction, by applying controlled pressure to increase local blood flow and reduce the risk of movement during the lancing procedure.
The clamping mechanism in the integrated diagnostic device plays a crucial role in reducing pain during the finger-piercing process. By immobilizing the finger securely between the adjustable jaw and the fixed immobilizer, the device creates a stable environment that minimizes any involuntary movements. This stability is essential, as it allows for precise lancet placement, ensuring that the puncture is accurate and controlled. Furthermore, the gentle compression applied by the mechanism creates a “bubble” effect in the finger pad, increasing local blood flow while maintaining a thinner skin surface at the puncture site. This hemodynamic effect helps to reduce the pain experienced during the lancing, as a well-prepared site allows for a more effective and less traumatic penetration.
Additionally, the soft padding integrated into the clamping mechanism enhances user comfort by providing a gentle grip on the finger. This padding not only protects the skin but also prevents excessive pressure that could lead to bruising or discomfort. By carefully controlling the clamping force, the device reduces the depth of penetration required by the lancet, further minimizing pain. Potential feedback mechanisms, including tactile and auditory signals, inform users when the finger is optimally secured, adding to their confidence and reducing anxiety associated with the lancing process. Together, these features ensure a more comfortable experience, making blood sampling easier and less distressing for users.
The clamping mechanism consists of several key components, all housed within the device's outer casing. These include: 1) Adjustable Jaw: a movable, adjustable jaw is responsible for securing the user's finger in place. This jaw moves along a predetermined linear path, driven by a linear actuator, which is controlled manually via a thumb-operated slider or electronically through an internal motor; 2) Immobilizer: on the opposite side of the adjustable jaw is a fixed or semi-fixed immobilizer. The immobilizer presses against the dorsal (upper) side of the finger, acting as a cushion to protect the user's skin while preventing movement during the procedure; 3) Padding: to ensure user comfort, the inner surfaces of both the adjustable jaw and immobilizer are lined with soft padding. This padding provides a secure, but gentle, grip on the finger, reducing discomfort and preventing excessive pressure that could cause bruising; and 4) Linear Actuator: the linear actuator enables precise movement of the adjustable jaw. It may be manually operated by a thumb slider or lever that drives the jaw forward and backward. In more advanced versions, the actuator could be powered by a small motor controlled by an onboard processor, allowing for automatic adjustments based on the user's finger size.
In terms of operation of the clamping mechanism, it is designed to operate in a seamless, user-friendly manner. The mechanism works in the following step-by-step manner: 1) Finger Placement: the user inserts their finger into a finger “cradle” or finger padding located between the adjustable jaw and the immobilizer. The finger padding helps guide the finger into the correct position, ensuring that the sampling area (usually the fingertip or the side of the finger) aligns with the lancet assembly; 2) Clamping Activation: once the finger is positioned correctly, the user activates the clamping mechanism. This can be done by sliding a thumb-operated lever or pressing a button, depending on the device's design. The linear actuator moves the adjustable jaw towards the immobilizer, applying gentle, even pressure to the finger; 3) Controlled Compression: as the adjustable jaw tightens, it creates controlled compression on the skin. This compression serves two main functions: a) Immobilization: by holding the finger securely in place, the clamping mechanism prevents any involuntary movements during the lancing procedure, ensuring that the lancet hits the target location with precision, and b) Increased Blood Flow: the slight pressure applied by the clamping mechanism enhances local blood flow by compressing the surrounding tissue and temporarily increasing the blood pressure in the area by at least 5 mmHg. This hemodynamic effect is crucial for ensuring that a sufficient sample of blood can be collected with a single lancet prick; 4) Feedback Mechanism: to enhance user confidence and improve accuracy, the device may include a feedback mechanism. This could take the form of: a) Tactile Feedback: a click or vibration when the correct clamping pressure is reached; b) Visual Feedback: a LED indicator or digital display that turns green when the finger is clamped securely and is ready for lancing; and c) Auditory Feedback: a soft beep or chime that signals the user to proceed with the next step; 5) Lancing and Blood Collection: once the finger is clamped securely, the user activates the lancet mechanism to pierce the skin and collect the blood sample. The controlled pressure exerted by the clamping mechanism ensures that the puncture is consistent and effective, allowing blood to pool at the puncture site for easy collection; and 6) Release: after the sample is collected, the user deactivates the clamping mechanism by releasing the thumb slider.
As an integral part of the integrated diagnostic device, the clamping mechanism provides: 1) Consistency in Sampling: the clamping mechanism guarantees consistent placement and immobilization of the finger, reducing variability in lancet penetration depth and blood collection. This leads to more reliable test results across repeated uses; 2) Improved Blood Flow: by applying controlled pressure, the clamping mechanism increases blood perfusion to the puncture site. This allows for faster and more efficient blood collection, particularly for individuals with poor circulation or for tests that require larger blood samples; 3) Reduced Pain and Discomfort: the soft padding on the jaw and immobilizer provides comfort during the clamping process. Additionally, the mechanism's controlled compression minimizes the depth of penetration required by the lancet, reducing the pain associated with lancing; 4) Safety and Precision: immobilizing the finger reduces the risk of lateral movement or jerking, which could cause accidental injury or inaccurate lancing. The feedback system ensures that the user knows when the device is correctly positioned and ready for use; and 5) Ease of Use: the simple thumb-operated design makes the clamping mechanism intuitive to use, even for individuals with limited dexterity. This is especially beneficial for elderly patients or those with conditions like arthritis.
In some embodiments of the device, the clamping mechanism may feature advanced automation and adaptability, as follows: 1) Automated Clamping: instead of manual operation, the clamping mechanism could be fully automated, with the adjustable jaw moving into place once the device detects a finger has been inserted. Sensors could monitor the amount of pressure being applied and adjust accordingly to optimize blood flow without causing discomfort; 2) Adjustable Pressure Settings: for users with specific medical conditions, such as peripheral artery disease or diabetes, where circulation may be impaired, the device could feature adjustable pressure settings. This would allow for more or less compression based on individual needs; and 3) Smart Sensors: Integrated sensors could detect the thickness of the user's finger and automatically adjust the clamping pressure to match, providing a more personalized and effective experience.
In some embodiments, the clamping mechanism may include a manually operated actuator (e.g., a lever or dial) that allows the user to adjust the clamping force. The force applied by the immobilizer and finger padding can be increased or decreased based on the user's preference or specific physiological needs (e.g., sensitive skin, reduced blood flow). The manual adjustability provides fine control over the creation of the “bubble” on the finger pad, ensuring optimal tension in the skin for efficient blood sampling.
In another embodiment, the clamping mechanism may be fully automated. The device is equipped with smart sensors that detect the size, thickness, and temperature of the user's finger. The clamping force is automatically adjusted to ensure the correct tension is applied to the finger pad, creating the “bubble” under ideal conditions. This automated system ensures consistency and reduces user error. Additionally, the smart sensors could provide real-time feedback on blood pressure in the clamped area, ensuring that the desired increase in local blood pressure (e.g., by 5 mmHg) is achieved before lancing.
In some embodiments, the clamping mechanism may be designed with multi-position functionality, allowing it to adjust to different areas of the finger. For example, the mechanism could allow sampling from the side of the finger, where the skin is thinner and often less painful to pierce, or from the center of the pad, where more blood flow may be present. This flexibility provides users with options to choose the most comfortable and efficient sampling location. In further embodiments, the clamping mechanism may include dynamic tension control by using a microprocessor-controlled actuator to gradually increase or decrease the clamping pressure in response to real-time feedback. The device could monitor skin tension and blood flow beneath the immobilized finger pad, adjusting the clamping force dynamically to maintain the ideal conditions for a painless, efficient blood sample.
In some embodiments, the lancet mechanism involves a spring-assisted lancet with an adjustable speed and depth of penetration. The user may select from predefined settings that modify the speed of the lancet based on their sensitivity or blood flow characteristics. For example, the device may include multiple preset modes, such as “Sensitive Mode” for users with delicate skin and “High Flow Mode” for users with reduced circulation. These adjustments optimize the sampling process to avoid unnecessary pain while ensuring sufficient blood collection.
In another embodiment, the lancet mechanism includes a predefined safety stop that ensures the lancet cannot penetrate too deeply. This prevents the lancet from causing excessive injury or discomfort, particularly for users with thin or delicate skin. The constant velocity of the lancet's movement ensures consistent results across multiple uses, reducing the need for resampling due to insufficient blood collection.
In yet another embodiment, the lancet mechanism could feature a multi-lancet cartridge system. This system allows for multiple lancets to be loaded into the device at once, enabling consecutive blood sampling without the need for reloading the lancet after each use. The multi-lancet system could be particularly beneficial in clinical settings where rapid testing of multiple patients is required, or for users who need frequent blood monitoring.
In further embodiments, the device includes an automated lancet mechanism with integrated blood flow detection sensors. After the clamping mechanism creates the “bubble” within the finger pad of the user, and the tension in the skin is optimized, the lancet is deployed automatically once the device detects sufficient blood flow beneath the skin. This feature ensures that the lancet only activates when the blood sample is likely to be adequate, reducing the chances of failed lancing attempts and preventing unnecessary repeat samplings.
In another embodiment, the lancet mechanism includes a micromotor-controlled lancet. Instead of relying solely on spring tension, the lancet is driven by a micromotor that ensures absolute control over the speed, depth, and retraction of the lancet. This mechanism allows for precision lancing, particularly useful for users with conditions that affect blood clotting or skin integrity, as it allows for precise, shallow penetrations with minimal trauma.
One embodiment of the device integrates a pre-lancing blood pressure monitoring system within the clamping mechanism. The device is equipped with sensors that measure local blood pressure in the finger before and after clamping. The clamping force is then adjusted to ensure that the increase in local blood pressure (e.g., at least 5 mmHg) is achieved before the lancet is triggered. This ensures optimal conditions for blood sampling and reduces the need for multiple lancing attempts.
Another embodiment involves the device incorporating temperature sensors to adjust the clamping force and tension based on the user's skin temperature. Warmer skin typically has better blood flow, while cooler skin may require additional tension to achieve sufficient blood pooling. The device dynamically adjusts to the user's temperature, optimizing the formation of the “bubble” within the finger pad of the user, and ensuring efficient blood extraction.
In a further embodiment, the clamping mechanism includes a timed pressure release system. After the lancet pierces the skin, the clamping force is briefly increased and then gradually released over a few seconds, promoting enhanced blood flow to the puncture site. This technique reduces the chance of incomplete blood samples and improves the overall efficiency of the sampling process. As an example, the system may be provided as a-or as a part of a device, utilizable as a glucometer, for testing (capillary) blood glucose concentration: it is a small and portable, ready-to-use, single-use, disposable glucometer characterized by both non-tedious and intuitively-operated, free of pain and anxiety for pain or discomfort, and improved user experience.
In some embodiments, a glucometer in an elongated device having a main longitudinal axis A:A, in one embodiment of the invention, lateral cross-section (perpendicular to axis A:A) of the device is circular or oval. Alternatively, at least a portion of the cross section is polygonal (not shown). The glucometer comprises, inter alia, a head portion, a body portion and analyzing strip (e.g., diabetes test strip30). Various diabetes test strips are commercially available, including e.g., Accu-Chek Aviva Plus™ test strips or Accu-Chek SmartView™ test strips, by Roche Diabetes Care, Inc. (US); FreeStyle™ Abbott Precision Xtra™ Strips, by Abbott (US); GE200™ Test Strips by GE (US).
In some embodiments, the head portion may comprise gripping protrusions enabling rotation of the head portion around the main axis relatively to the body. Rotation of the head may facilitate or otherwise enable actuation of a lancet (not shown, positioned, e.g., fleshy underside of the end of a body portion to be pierced, e.g., a finger pad). The lancet is accommodated within portions of the head and/or body, and positioned in parallel with the main axis, e.g., in a concentric or eccentric manner.

This is a case report of a young healthy pregnant woman, on her first pregnancy, that illustrates the need for the aspect of the present invention concerned with in checking for diabetes during pregnancy.
At the beginning of her pregnancy, at about her 12th week of gestation, she was found to have normal fasting glucose level of 80 mg %. There was no history of diabetes in her close family. The next glucose test, glucose challenge test (GCT), that was taken on her 24th week of gestation, showed abnormal value of 300 mg %. She was then sent to the High Risk Pregnancy clinic, but within few days, before reaching the clinic, she was admitted to the emergency room with severe ketoacidosis. Going forward she was delivered by emergency cesarean section. The new born was severely handicapped.
The aforementioned case shows that more frequent blood glucose tests as provide by the present invention could have helped in detecting the situation at an earlier stage, avoiding the severe outcome. Considering the difficulty and expenses of being admitted every week to the clinic to check for blood glucose level or having every pregnant woman purchasing and carrying a personal glucose meter, it seems that the idea of a single use self-testing, painless and low-cost blood glucose test, SmarTest, would solve these problems.
