Description

Technical Field

[0001] This invention relates to the field of medical device technology, and more specifically, to a non-invasive cerebrospinal fluid pressure monitoring device. Background Technology

[0002] Non-invasive cerebrospinal fluid pressure monitoring is an advanced medical device whose core function is to accurately and continuously monitor cerebrospinal fluid pressure without any invasive procedures. This device relies on specific technologies and highly sensitive sensors to effectively acquire real-time data and related parameters of cerebrospinal fluid pressure in a non-invasive manner. This data is not only accurate and reliable but also provides crucial reference for medical personnel in diagnosing diseases, assessing disease progression, and developing scientific and reasonable treatment plans. Due to its unique non-invasive monitoring advantages, non-invasive cerebrospinal fluid pressure monitoring has demonstrated widespread application demand and irreplaceable clinical value in various clinical departments such as neurosurgery and neurology, becoming an indispensable tool in modern medical diagnosis and treatment.

[0003] According to patent document CN104274170B, an intracranial pressure monitoring device is disclosed. The drainage tube has a drainage hole at its drainage end, and an inflatable air bag is fitted around the drainage end of the tube. An inflation device that can slide along the drainage tube is fitted over the drainage conduit. The drainage tube includes a drainage cavity and a pressure measuring cavity. The end of the drainage cavity is fixedly connected to a drainage branch tube connector, and the end of the pressure measuring cavity is fixedly connected to a pressure measuring branch tube connector. The pressure measuring branch tube connector is connected to a monitoring display via a pressure sensing device. The monitoring display has a pressure sensor box, a power supply box, and a display screen on its side. The pressure sensor box and the power supply box each contain a wound wire post and a socket. The advantages of this invention are: it can simultaneously achieve cerebrospinal fluid drainage and intracranial pressure measurement, enabling real-time monitoring, saving time for rescue, and the multiple openings reduce the risk of infection and dislodgement, thus alleviating patient suffering.

[0004] Traditional non-invasive cerebrospinal fluid pressure monitors typically use both a power source and a battery to provide power. However, this approach has several drawbacks. First, simultaneously powering the device with both a power source and a battery can lead to wasted energy, as the battery's power is not fully utilized and is simply consumed. Second, this power supply method can negatively impact battery lifespan. Typically, non-invasive cerebrospinal fluid pressure monitors are equipped with traditional lithium batteries. If the device is powered by both a power source and a battery, the battery may overcharge. Overcharging not only shortens battery life but can also pose safety hazards. Therefore, to improve the power supply efficiency and safety of non-invasive cerebrospinal fluid pressure monitors, a more efficient power supply method needs to be found. Summary of the Invention

Rotating rod hinge blocks 224 are fixedly connected to both the front and rear sides of the power connection block body 221. Rotating rods 225 are rotatably connected to both sides of the bottom inner wall of the two rotating rod hinge blocks 224. The side of the two sets of rotating rods 225 away from the rotating rod hinge blocks 224 is rotatably connected to the inner wall of the two sets of hinge blocks 21116. When a power supply mode needs to be changed, especially when the battery 21121 is needed to provide power, the electric push rod 21119 must be activated first. After activation, the electric push rod 21119 will apply a pushing force to the battery bottom plate 21122, so that it moves smoothly and accurately upward along the preset guide groove 2112 under the continuous push of the electric push rod 21119. This movement not only drives the battery bottom plate 21122 itself, but also further causes the battery 21121 to slide upward along the predetermined track inside the rectangular frame 21120. As the battery 21121 continues to rise, the male connector 21124 at its top gradually approaches the power connection female block body 221, preparing for the subsequent electrical connection. At the same time, the upward movement of the battery bottom plate 21122 also pulls the convex slide plate 21110 to slide upward synchronously on the guide rod 2114 through the columnar push-pull rod 21123 connected to it. The upward movement of the convex sliding plate 21110 further drives the connected second connecting block 21111 and the second rotating inclined rod 2117 to move upward together. This series of movements causes a significant change in the relative angle between the rotating inclined rod 2116 and the second rotating inclined rod 2117. This angle change is transmitted through the columnar connecting rod 2118 and the connecting block 2119, and finally acts on the expansion plate 21113, causing it to expand outward. The expansion action of the expansion plate 21113 further drives the convex push-pull plate. 21114 moves outward. The movement of the convex push-pull plate 21114 is linked by the inverted L-shaped rotating block 2126 and rotating block 2125, so that the positioning rod 2127 slides precisely at the middle position of the second concave guide block 2124 and the concave guide block 2122. When the male connector 21124 at the top of the battery 21121 is successfully connected to the bottom of the power receiving female block body 221, the inner structure of the two second concave guide blocks 2124 will stably position the battery 21121 to ensure the reliability of the connection. As the two expansion plates 21113 move outward, they also drive the two expansion base plates 21115 to move outward, which in turn causes the hinge block 21116 to also move outward. The displacement of the hinge block 21116 causes the rotating rod 225, which is rotatably connected to it, to change its angle. Under the constraint of the rotating rod hinge block 224, the end of the rotating rod 225 away from the hinge block 21116 will drive the power connection female block body 221 to the inside of the guide side upright plate 2129. Through the sliding cooperation of the power connection female block slider 223, stable and precise position fine adjustment is achieved, ensuring that the male connector 21124 and the electrical interface at the bottom of the power connection female block body 221 can be accurately connected, and the power supply connection switching between the battery 21121 and the monitoring instrument body 1 can be successfully completed. At this time, the entire power supply switching mechanism 2 is in a stable state of battery power supply. The main body of the monitoring instrument 1 can continue to operate stably with the power provided by the battery 21121. If it is necessary to switch the power supply mode back to other modes in the future, the electric push rod 21119 can be reversed through the control system to drive the above-mentioned components to perform reverse actions, so that the male connector 21124 is separated from the power connection female block 221, and the components gradually return to their initial positions so as to connect to other power sources and ensure the flexibility and reliability of the power supply system.

[0022] Working principle of this invention: When it is necessary to change the power supply mode and use battery 21121 for power supply, the electric push rod 21119 is first activated to push the battery bottom horizontal plate 21122. Under the push of the electric push rod 21119, the battery bottom horizontal plate 21122 moves upward along the guide groove 2112, thereby causing the battery 21121 to slide and rise within the rectangular frame 21120. As the battery 21121 rises, the male connector 21124 gradually approaches the power connection female block body 221, preparing for electrical connection. At the same time, the rise of the battery bottom horizontal plate 21122 also pulls the convex sliding plate 21110 upward on the guide rod 2114 through the columnar push-pull rod 21123. The rising of the convex sliding plate 21110 causes the second connecting block 21111 and the second rotating inclined rod 2117 to move upward, thereby changing the angle between the rotating inclined rod 2116 and the second rotating inclined rod 2117. This change is transmitted to the expanding plate 21113 through the columnar connecting rod 2118 and the connecting block 2119, causing the expanding plate 21113 to expand outward. The expansion of the expanding plate 21113 then causes the convex push-pull plate 21114 to move outward. The movement of the push-pull plate 21114 causes the positioning rod 2127 to slide between the second concave guide block 2124 and the concave guide block 2122 via the inverted L-shaped rotating block 2126 and the rotating block 2125. When the male connector 21124 at the top of the battery 21121 is connected to the bottom of the female connector body 221, the inner sides of the two second concave guide blocks 2124 position the battery 21121. When the two retractable expansion plates 21113 move outward, they simultaneously drive the two retractable expansion plates to move outward. The expansion plate 21115 moves outward, which in turn causes the hinge block 21116 to move outward. The displacement of the hinge block 21116 causes the rotating rod 225, which is rotatably connected to it, to change its angle. This causes the main body 221 of the power connection block to slide inside the guide side plate 2129 through the sliding engagement of the power connection block slider 223, achieving stable position fine adjustment. This ensures that the male connector 21124 and the electrical interface at the bottom of the power connection block 221 are accurately connected, completing the power supply connection switch between the battery 21121 and the monitoring instrument main body 1. At this time, the entire power supply switching mechanism 2 is in a stable state of battery power supply. The monitoring instrument main body 1 continues to operate on the power provided by the battery 21121. If it is necessary to switch back to other power supply modes, simply control the electric push rod 21119 to operate in reverse, causing the above-mentioned components to move in reverse, so that the male connector 21124 is separated from the power connection block 221, and the components return to their initial positions so that other power supplies can be connected.
