Abstract
Description
Technical Field
[0001] This invention relates to the field of blood collection chair technology, and in particular to an intelligent blood collection chair equipped with a bio-verification system. Background Technology
[0002] In modern medical blood collection procedures, ensuring accurate identification of the blood collection subject and the standardization and accuracy of the blood collection process are of paramount importance.
[0003] Currently, the patient identity verification methods used in blood collection have significant limitations. Traditional identity verification methods, such as manual verification of patient information, rely on the subjective judgment and operation of medical staff, making it difficult to completely avoid human error. In practice, medical staff may become negligent due to heavy workloads or distractions, leading to frequent misjudgments. Once a misjudgment occurs, it is highly likely to result in incorrect blood collection, which not only seriously violates the principle of rigorous medical procedures but also poses a potential threat to the legitimate rights and interests of patients.
[0004] Meanwhile, there are loopholes in the management of patient identity verification during the pre-blood collection preparation process. Some patients may place their arms on the armrests or other parts of the blood collection chair before completing identity verification. This makes it difficult for medical staff to quickly and accurately determine whether the patient has passed valid identity verification, thus introducing the risk of non-standard procedures into the blood collection process and affecting the orderly conduct and overall quality of the blood collection work. Summary of the Invention
[0005] This invention relates to an intelligent blood collection chair equipped with a biometric verification system, which solves the problems of traditional identity verification methods during blood collection being prone to misjudgment and mis-collection due to human factors, affecting the rigor of medical care and the rights and interests of patients, and the lack of management of the patient's identity verification status before blood collection, which allows the arm to be placed before verification is passed, increasing the risk of non-standard operation.
[0006] This invention provides an intelligent blood collection chair equipped with a biometric verification system, specifically comprising: a base; an armrest block b fixedly installed on the right end face of the base, with a fingerprint sensor embedded in the top surface of the armrest block b adjacent to the front side; an armrest block a fixedly installed on the left end face of the base, with a display screen installed on the top surface of the armrest block a adjacent to the rear side; a microcontroller electrically connected to the fingerprint sensor and the display screen is provided inside the base, and the base is connected to an external power supply; a power switch electrically connected to the microcontroller is installed on the left end face of the armrest block a; the base also contains a database and a comparison module electrically connected to the microcontroller, the database storing patient identity information and medical records.
[0007] Furthermore, a chair seat is fixedly mounted on the top surface of the base via a support block, and a pressure sensor is installed inside the chair seat. The pressure sensor is electrically connected to the microcontroller.
[0008] Furthermore, a rear support block is fixedly installed on the rear side of the top surface of the base; a lumbar support is provided on the upper rear side of the chair seat, and the lumbar support is fixedly connected to the rear support block; a back support is provided above the lumbar support, and the back support is fixedly connected to the rear support block; a headrest is provided above the backrest, and the headrest is fixedly connected to the rear support block.
[0009] Furthermore, a storage cavity is provided inside the handrail block b, and a set of motors is fixedly installed on the top surface of the storage cavity. The motors are electrically connected to the microcontroller. A circular plate-shaped wiping plate is provided on the upper side of the handrail block b, and the shaft end of the motor passes through the top surface of the handrail block b and is fixedly connected to the central part of the wiping plate.
[0010] Furthermore, a cut surface is provided on the outer periphery of the wiping plate, and a wiping cotton with the same outline size is fixedly adhered to the bottom end of the wiping plate; when the motor is not running, the cut surface faces the fingerprint sensor, and the wiping plate does not block the fingerprint sensor; when the cut surface faces the fingerprint sensor, the wiping plate covers and blocks the fingerprint sensor, and the wiping cotton is in contact with the fingerprint sensor.
[0011] Furthermore, a square-shaped storage groove is provided on the top surface of the handrail block a adjacent to the front side. A set of electric push rods is fixedly installed on the bottom surface of the inner end of the storage groove. The electric push rods are electrically connected to the microcontroller. The push rod end of the electric push rod faces directly upward, and a square-shaped rubber obstruction block is fixedly installed on the push rod end of the electric push rod.
[0012] Furthermore, when the push rod end of the electric push rod is retracted, the top surface of the rubber obstruction block and the top surface of the handrail block a are at the same horizontal plane.
[0013] Furthermore, when the pressure sensor senses pressure, it sends a feedback signal to the microcontroller, which controls the motor shaft to rotate one revolution and simultaneously controls the extension of the electric actuator's push rod end. When the fingerprint information collected by the fingerprint sensor is compared and matched with the fingerprint information in the database through the comparison module, the microcontroller controls the extension of the electric actuator's push rod end to retract.
[0014] This invention provides an intelligent blood collection chair equipped with a bio-validation system, which has the following beneficial effects:
[0015] This invention utilizes the feedback from a pressure sensor to detect pressure when a patient sits on a chair and transmits the feedback signal to a microcontroller. This microcontroller controls the motor shaft to rotate one revolution, which in turn rotates the wiping plate. The wiping pad is then used to clean the fingerprint sensor, ensuring its surface remains clean and allowing for accurate fingerprint data collection. This improves the accuracy and reliability of fingerprint acquisition.
[0016] Based on the feedback of a pressure sensor, this invention can simultaneously control the extension of the push rod end of the electric push rod when the patient sits down, pushing the rubber obstruction block upward so that it is higher than the top surface of the armrest block a. This effectively prevents the patient from placing their arm flat on the top surface of the armrest block a before identity verification, thus achieving preliminary obstruction before blood collection and avoiding blood collection without identity verification, ensuring the standardization of blood collection operations.
[0017] This invention is equipped with a biometric verification system that uses a high-precision fingerprint sensor to collect fingerprints and, through a rigorous comparison and verification process, accurately confirms the patient's identity. Once a fingerprint verification is successful, the system automatically and clearly displays the corresponding patient identity information and detailed medical records on the screen. This design allows medical staff to intuitively and quickly obtain key information, thus greatly ensuring the accuracy and safety of blood collection procedures. Simultaneously, the system automatically controls the rubber retainer to reset, ensuring it no longer obstructs the patient's arm from lying flat, providing convenience and allowing the patient to easily and comfortably position their arm for smooth blood collection.
[0018] This invention uses a rubber barrier block to prevent the fingerprint information from matching. When the fingerprint information does not match, the pusher end of the electric push rod does not retract, and the rubber barrier block remains above the top surface of the handrail block a, preventing the patient's arm from being placed flat. This silently reminds medical staff that the patient's identity verification has failed and that other verification methods need to be used, effectively avoiding false fingerprinting and maximizing the rigor of medical operations and the rights of patients.

[0033] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the described embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0034] Example: Please refer to Figures 1 to 9 :
[0035] This invention proposes an intelligent blood collection chair equipped with a biometric verification system, comprising: a base 1, an armrest block b102 fixedly mounted on the right end face of the base 1, and a fingerprint sensor 109 embedded in the top surface of the armrest block b102 adjacent to the front side; an armrest block a101 fixedly mounted on the left end face of the base 1, and a display screen 107 mounted on the top surface of the armrest block a101 adjacent to the rear side; a microcontroller 1017 electrically connected to the fingerprint sensor 109 and the display screen 107 is provided inside the base 1, and the base 1 is externally powered; a power switch 108 electrically connected to the microcontroller 1017 is installed on the left end face of the armrest block a101; and a database 1015 electrically connected to the microcontroller 1017 is also provided inside the base 1. The database 1015 stores patient identity information and medical records, along with the comparison module 1016. A chair seat 103 is fixedly installed on the top surface of the base 1 via a support block 1011. A pressure sensor 1012 is installed inside the chair seat 103 and is electrically connected to a microcontroller 1017. A rear support block 1010 is fixedly installed on the rear side of the top surface of the base 1. A lumbar support 104 is provided on the upper rear side of the chair seat 103 and is fixedly connected to the rear support block 1010. A back support 105 is provided above the lumbar support 104 and is fixedly connected to the rear support block 1010. A headrest 106 is provided above the backrest 105 and is fixedly connected to the rear support block 1010.
[0036] The armrest block b102 has a storage cavity 1013 inside, and a set of motors 303 are fixedly installed on the top surface of the storage cavity 1013. The motors 303 are electrically connected to the microcontroller 1017. A circular wiping plate 3 is provided on the upper side of the armrest block b102. The shaft end of the motor 303 passes through the top surface of the armrest block b102 and is fixedly connected to the axis of the wiping plate 3. A cut surface 301 is provided on the outer peripheral surface of the wiping plate 3, and a wiping cotton 302 with the same outline size is fixedly adhered to the bottom surface of the wiping plate 3. When the motor 303 is not running, the cut surface 301 faces the fingerprint sensor 109, and the wiping plate 3 does not block the fingerprint sensor 109. When the cut surface 301 faces the fingerprint sensor 109, the wiping plate 3 covers and blocks the fingerprint sensor 109, and the wiping cotton 302 is in contact with the fingerprint sensor 109.
[0037] The top surface of the handrail block a101 has a square-shaped storage groove 1014 adjacent to the front side. A set of electric push rods 201 are fixedly installed on the bottom surface of the inner end of the storage groove 1014. The electric push rods 201 are electrically connected to a microcontroller 1017. The push rod end of the electric push rod 201 faces directly upwards, and a square-shaped rubber obstruction block 2 is fixedly installed on the push rod end of the electric push rod 201. When the push rod end of the electric push rod 201 is retracted, the top surface of the rubber obstruction block 2 is flush with the handrail block a101. 1. The top surface is at the same level. When the pressure sensor 1012 senses pressure, the pressure sensor 1012 sends a feedback signal to the microcontroller 1017. The microcontroller 1017 controls the shaft end of the motor 303 to rotate one revolution and simultaneously controls the push rod end of the electric push rod 201 to extend. When the fingerprint information collected by the fingerprint sensor 109 is compared and matched with the fingerprint information in the database 1015 through the comparison module 1016, the microcontroller 1017 controls the push rod end of the electric push rod 201 in the extended state to retract.
[0038] The working principle of this embodiment:
[0039] The smart blood collection chair is turned on by pressing the power switch 108 on the left side of the armrest block a101.
[0040] When the patient sits on the chair 103, the pressure sensor 1012 inside the chair 103 senses the pressure and sends a feedback signal to the microcontroller 1017. After receiving the signal from the pressure sensor 1012, the microcontroller 1017 controls the shaft of the motor 303 to rotate one revolution, causing the wiping plate 3 to rotate. During the rotation, the wiping cotton 302 wipes and cleans the fingerprint sensor 109 to ensure that the surface of the fingerprint sensor 109 is clean and can accurately collect fingerprint information.
[0041] At the same time, the microcontroller 1017 controls the extension of the push rod end of the electric push rod 201, and the push rod end of the electric push rod 201 pushes the rubber blocking block 2 upward. At this time, the rubber blocking block 2 is higher than the top surface of the handrail block a101, forming a clear barrier. This barrier effectively prevents the patient from placing their arm flat on the top surface of the handrail block a101, thus achieving the initial barrier before blood collection and avoiding blood collection before identity verification is completed.
[0042] At this time, the patient can place their finger on the fingerprint sensor 109 to collect fingerprints. The fingerprint sensor 109 transmits the collected fingerprint information to the microcontroller 1017. The microcontroller 1017 sends the received fingerprint information to the comparison module 1016. The comparison module 1016 compares the collected fingerprint information with the fingerprint information stored in the database 1015. When the fingerprint information collected by the fingerprint sensor 109 matches the fingerprint information in the database 1015 through the comparison module 1016, the microcontroller 1017 controls the push end of the electric push rod 201, which is in the extended state, to retract. The top surface of the rubber obstruction block 2 and the top surface of the handrail block a101 are once again at the same level. At this time, the patient's arm can be placed flat on the top surface of the handrail block a101 to facilitate blood collection and other operations. At the same time, the patient's identity information and medical records corresponding to the fingerprint information are displayed on the display screen 107 for easy observation by medical staff, thereby ensuring the accuracy and safety of the blood collection operation.
[0043] If the fingerprint information does not match, the retraction of the electric push rod 201 will not be executed. As a result, the rubber obstruction block 2 will remain above the top surface of the handrail block a101, and the patient's arm will not be able to rest flat on the top surface of the handrail block a101. This situation acts as a silent reminder to medical staff that the patient's identity verification has failed and other verification methods are needed to ensure that no false fingerprints are collected, thus maximizing the rigor of medical procedures and protecting the rights of patients.
