Technical Field
[0001] This invention relates to the field of wearable device technology, specifically to a wearable integrated patch device for continuous blood flow monitoring and micro-blood sampling. Background Technology
[0002] Wearable devices refer to the intelligent configuration of people's daily wearables using wearable technology.

They are characterized by small size, light weight and high level of informatization and cover fields such as industrial manufacturing, medical health, information entertainment, education and teaching, sports and other fields. Blood flow monitoring is a commonly used monitoring item in wearable devices. It can determine the user's blood pressure data and the user's health status by measuring the blood flow velocity.
[0003] However, existing blood flow monitoring still has shortcomings, specifically: existing wearable devices cannot perform continuous monitoring and micro-blood sampling, making them relatively inconvenient to use. Summary of the Invention
[0004] The purpose of this invention is to provide a wearable continuous blood flow monitoring and micro-blood sampling integrated patch device to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0008] As a preferred embodiment of the present invention, the protective shell is made of ABS plastic, the fixing strap is made of nylon fiber weaving, the battery, the charging electrode plate and the touch control screen are connected by a uniform electrical connection, and the touch control screen internally stores a deep learning algorithm that uses ultrasound data to calculate blood flow velocity.
[0009] As a preferred embodiment of the present invention, the protective shell has a U-shaped structure design, and a sealing plug is slidably connected to the outer wall of the protective shell at the corresponding position of the charging electrode plate. A connecting rope is fixedly connected to the outer wall of the sealing plug, and the connecting rope is fixedly connected to the protective shell.
[0010] Through the above technical solution, the sealing plug can prevent dust in the air from contaminating the charging electrode plate, and the connecting rope can make it convenient for users to pull out the sealing plug while also preventing the sealing plug from falling off the protective shell.
[0011] As a preferred embodiment of the present invention, the connecting strip is made of pressure-sensitive adhesive, four sets of the reset spring and electromagnet are provided, the guide tube is designed with an L-shaped structure, and the reset spring, the spiral spring and the protective shell are all fixedly connected.
[0012] The above technical solution allows users to easily replace microneedle array patches by using pressure-sensitive adhesive connecting strips.
[0013] As a preferred embodiment of the present invention, the guide tube is made of multiple sets of capillaries, the guide tube passes through the extrusion plate and extends into the protective housing, the push block is provided in two sets, and the connection between the guide tube and the extrusion plate, and the connection between the card block and the placement plate are all sliding connections.
[0014] As a preferred embodiment of the present invention, the placement plate has an L-shaped structure design, and both the connecting shaft and the placement plate extend through and out of the protective shell. Multiple sets of flexible ultrasonic patches are provided, and the connection between the flexible ultrasonic patches, the electromagnet and the touch control screen is all electrical connection.
[0015] As a preferred embodiment of the present invention, the extrusion sheet is made of stainless steel and has a U-shaped structure design. The outer walls of the protective shell and the fixing band are provided with grooves at the corresponding positions of the microneedle array patch.
[0016] Compared with the prior art, the beneficial effects of the present invention are:
[0017] 1. In this invention, a wearable continuous blood flow monitoring and micro-blood collection integrated patch device is set up. The monitoring mechanism in this device is used for blood flow monitoring. A fixing strap is attached to the user's body. The touch control screen activates the flexible ultrasonic patch, which emits and receives ultrasonic waves into the user's body. The touch control screen processes the received ultrasonic data to obtain data on changes in the user's blood vessel diameter, which is then converted into blood pressure and blood flow velocity data. During blood collection, pushing the locking block causes it to rotate upwards and disengage from the placement plate. Pulling the placement plate removes it from the protective housing. The sample slide for blood collection is placed inside the protective housing. Pushing the placement plate again causes it to pull the sample slide into the protective housing. Releasing the locking block causes a spiral spring to drive the blood collection through a connecting shaft. The locking block rotates downwards, inserts into and locks the placement plate. The touch control screen deactivates the electromagnet, which no longer holds the squeezing plate. The return spring pushes the squeezing plate and the pushing block outwards. The outward-moving squeezing plate, through the pushing block, squeezes the microneedle array patch downwards. The microneedle array patch pierces the blood vessels in the user's skin, and the blood in the blood vessels flows into the microneedle array patch. The touch control screen reactivates the electromagnet, which attracts the squeezing plate. The attracted squeezing plate moves upwards and no longer presses against the microneedle array patch. The microneedle array patch detaches from the user's skin, and the flow tube composed of capillaries absorbs the blood from the microneedle array patch and drips the blood onto the sample slide, completing the blood collection. This solves the problem that existing wearable devices cannot achieve continuous monitoring and micro-blood collection functions, and are relatively inconvenient to use. Attached Figure Description
