Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to an intracranial pressure monitoring adapter and an intracranial pressure monitoring system. Background Technology

[0002] Intracranial pressure monitoring systems are generally divided into non-invasive and invasive systems. Non-invasive systems have not been widely used clinically due to drawbacks such as varying degrees of measurement inaccuracy, numerous limitations, complex methods, and susceptibility to various influencing factors. Invasive intracranial pressure sensor technology began development in the 1950s, and invasive intracranial pressure monitors were already in clinical use in the early 1960s. Currently, they are widely used clinically, providing a wealth of practical experience and data for intracranial pressure monitoring.

[0003] Invasive intracranial pressure monitoring systems typically consist of an invasive intracranial pressure sensor and an intracranial pressure monitor, and include wired and wireless intracranial pressure monitoring technologies. Invasive intracranial pressure monitoring requires placing an intracranial pressure sensor probe inside the skull. The sensor converts intracranial pressure and brain temperature into electrical signals, which are then transmitted to the intracranial pressure monitor for signal processing and display. The implantation time of the intracranial pressure sensor usually depends on the patient's specific condition and monitoring needs, generally ranging from 3 to 7 days.

[0004] However, current intracranial pressure monitoring sensors require battery power for both data acquisition and transmission. The battery life is insufficient for the 3-7 day clinical needs, and the integrated design of the sensor and battery poses an infection risk during battery replacement in sterile medical devices. Wired power supply also suffers from drawbacks, such as the need for regular cable management to prevent interference with other monitors, restricted patient movement, and the risk of accidental sensor detachment leading to wound dehiscence and infection. Wireless charging, on the other hand, has environmental requirements; excessive misalignment between the charging coil and the wireless charger coil can reduce charging efficiency or even cause charging interruptions, inconveniencing both patients and healthcare professionals.

[0039] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0040] It should be noted that the terms "first," "second," etc., in the specification, claims, and drawings of this utility model are used to distinguish different objects, not to limit a specific order. The following embodiments of this utility model can be performed individually or in combination with each other; this utility model does not impose specific limitations in this regard.

[0041] Intracranial pressure (IPP) is the pressure exerted by the contents of the cranial cavity on the walls of the cranial cavity. IPP monitoring is a technique used to monitor changes in intracranial pressure and is of great significance for the diagnosis, treatment, and prognostic assessment of neurological diseases. In the medical field, IPP monitoring can be divided into two main categories based on whether the diagnostic and treatment procedures cause trauma to the human body: invasive and non-invasive. Non-invasive IPP monitoring is not used clinically due to its poor measurement accuracy, numerous limitations, and many influencing factors. Invasive IPP monitoring, on the other hand, suffers from problems such as insufficient battery power for a single clinical monitoring session, and the risk of infection when changing the battery. Therefore, a simple and convenient battery-changing method that does not cause secondary infections is needed.

[0042] Figure 1 This is a structural diagram of an intracranial pressure monitoring adapter provided in an embodiment of the present invention.

[0043] The intracranial pressure monitoring adapter 100 is worn on the head of the target subject, such as... Figure 1 As shown, it includes an asynchronous transceiver interface 1 and a power module 2; the intracranial pressure monitoring adapter 100 is electrically connected to the intracranial pressure sensor 200 installed in the skull of the target object through the asynchronous transceiver interface 1; the power module 2 supplies power to the intracranial pressure sensor 200 through the asynchronous transceiver interface 1.

[0044] Specifically, the Universal Asynchronous Receiver Transmitter (UART) is a universal serial data bus transmission interface used for asynchronous communication. The UART is used not only to power the intracranial pressure sensor 200 and provide operating voltage, but also to exchange and transmit digital signals with the intracranial pressure sensor 200.

[0045] An intracranial pressure sensor 200 is placed inside the cranium of the target subject, and an intracranial pressure monitoring adapter 100 is worn on the target subject's head and electrically connected to the intracranial pressure sensor 200 via an asynchronous transceiver interface 1. After the intracranial pressure monitoring adapter 100 is connected to the intracranial pressure sensor 200, the power module 2 within the adapter 100 supplies power to the sensor 200 through the asynchronous transceiver interface 1. When the power module 2's power is insufficient, the sensor 200 can be powered by replacing the adapter 100 or by directly charging it. Furthermore, the replaced adapter 100 can be fully charged, sterilized, and reused. This not only avoids the problem of insufficient power for the sensor 200 within a single clinical cycle but also provides convenient power replacement without requiring secondary invasive procedures, thus avoiding the risk of infection.

[0046] This invention designs an intracranial pressure monitoring adapter. By setting a power module inside the intracranial pressure monitoring adapter and connecting it to the intracranial pressure sensor via an asynchronous transceiver interface for power supply, it solves the technical problem in the prior art that the battery power of the intracranial pressure sensor cannot meet the needs of the clinical monitoring cycle, while battery replacement poses an infection risk. It not only simplifies the battery replacement process but also achieves the technical effect of non-invasive battery replacement.

[0047] Figure 2 This is a structural diagram of another intracranial pressure monitoring adapter provided in this embodiment of the present invention.

[0048] Optionally, such as Figure 2 As shown, the intracranial pressure monitoring adapter 100 also includes an alarm module 3; the alarm module 3 is used to indicate the power information of the power module 2 and to issue an alarm when the intracranial pressure sensor 100 obtains abnormal intracranial pressure information.

[0049] Specifically, an alarm module 3 is set in the intracranial pressure monitoring adapter 100, which can monitor the current power information of the power module 2 at all times. If the power module 2 is currently in a power supply state, the power indicator light of the alarm module 3 can display the current power of the power module 2. When the power is low, it can be configured as needed to provide alarm actions such as flashing indicator light, color changing indicator light, and beeping sound to alert the target or medical staff. If the power module 2 is currently in a charging state, the power indicator light of the alarm module 3 is used to display the current charging progress and changes color when the power is fully charged.

[0050] If the intracranial pressure sensor 100 acquires abnormal intracranial pressure information, the alarm module 3 will issue an alarm prompt based on the control command sent by the power management module. This prompt can also be configured as an alarm action such as flashing indicator light, changing indicator light color, or emitting a buzzer sound, to remind the target or medical staff to detect abnormal data.

[0051] Optionally, such as Figure 2 As shown, the intracranial pressure monitoring adapter also includes a power management module 4;

[0052] Power module 2 and alarm module 3 are both electrically connected to power management module 4;

[0053] The power management module 4 is used to control the power module 2 to perform corresponding actions, and is also used to receive alarm instructions from the host computer 300, and control the alarm module to perform corresponding alarm actions based on the alarm instructions. The alarm instructions are generated by the host computer when it determines that there is an abnormality in the intracranial pressure information obtained by the intracranial pressure sensor based on the preset intracranial pressure standard.

[0054] Specifically, after the intracranial pressure sensor 200 acquires intracranial pressure information, it transmits the intracranial pressure information to the host computer through the intracranial pressure monitoring adapter 100. After receiving the intracranial pressure information, the host computer determines whether there is an abnormal intracranial pressure of the current target object based on the preset intracranial pressure standard. If so, it generates an alarm command and transmits it to the power management module 4 in the intracranial pressure monitoring adapter 100, so that the power management module 4 controls the alarm module 3 to perform the corresponding alarm action based on the received alarm command.

[0055] Optionally, such as Figure 2 As shown, the intracranial pressure monitoring adapter 100 also includes a wireless communication module 5; the wireless communication module 5 is electrically connected to the intracranial pressure sensor 200 through the asynchronous transceiver interface 1; the wireless communication module 5 is used to realize the communication connection between the intracranial pressure monitoring adapter 100 and the host computer 300.

[0056] Specifically, the power module 2 also supplies power to the wireless communication module 5, which acquires intracranial pressure information collected by the intracranial pressure sensor 200 through the asynchronous transceiver interface 1. This intracranial pressure information includes at least intracranial pressure data and brain temperature data. Subsequently, the wireless communication module 5 transmits the acquired intracranial pressure information to the host computer 300 via wireless communication technology, enabling the host computer 300 to display, store, and analyze the intracranial pressure information.

[0057] Optionally, the wireless communication module 5 includes at least one of the following: a Bluetooth Low Energy submodule and a wireless network communication submodule.

[0058] Specifically, the Bluetooth Low Energy (BLE) submodule is used to achieve wireless information transmission via Bluetooth Low Energy (BLE) technology, which has the advantages of low power consumption, low cost and strong anti-interference ability; the wireless network communication submodule is used to achieve wireless information transmission via Wi-Fi technology, which has the advantages of supporting real-time transmission of large amounts of data and wide signal coverage.

[0059] Optionally, the alarm module 3 includes a power indicator light, an alarm indicator light, and a buzzer; the power indicator light is used to indicate the power information of the power module 2; the alarm indicator light is used to flash to indicate when the intracranial pressure sensor 200 acquires abnormal intracranial pressure information; and the buzzer is used to sound to indicate when the intracranial pressure sensor 200 acquires abnormal intracranial pressure information.

[0060] Specifically, when the host computer 300 analyzes and detects abnormal conditions such as overpressure or overtemperature in the intracranial pressure information, it will send an alarm command to the power management module 4 through the wireless communication module 5. After receiving the alarm command, the wireless communication module 5 will drive the alarm indicator light to activate and drive the buzzer to sound an alarm.

[0061] For example, the alarm indicator can be configured to flash or change color when intracranial pressure information is abnormal, so that medical staff can receive visual alarm information; the alarm indicator can also be configured to flash or change color when the power module 2 has low power, so as to remind the target or medical staff that the power is low.

[0062] In addition, the power indicator light in alarm module 3 can be configured as follows: the power indicator light flashes to indicate that the power module 2 is charging or being powered by an external power source; the power indicator light stays on to indicate that the power module 2 is fully charged; the power indicator light changes color to indicate that the power module 2 is low on power.

[0063] Optionally, the power module 3 includes a lithium battery module and a battery charging interface; the lithium battery module is used to store electrical energy; the battery charging interface is connected to an external power source to charge the lithium battery module under the control of the power management module 4.

[0064] Specifically, the battery charging interface is used to connect an external power source to charge the lithium battery module or to power the ICP (Intracranial Pressure) wireless adapter online.

[0065] Optionally, the intracranial pressure monitoring adapter 100 also includes a soft rubber protective shell; the shape of the soft rubber protective shell is adapted to the head shape of the target object wearing the intracranial pressure monitoring adapter 100. An interface socket is provided on the soft rubber protective shell for connecting the asynchronous transceiver interface 1 to the intracranial pressure sensor 200.

[0066] Specifically, the intracranial pressure sensor 200 is used to fix the asynchronous transceiver interface 1 via an interface card slot, thereby connecting the asynchronous transceiver interface 1 to the intracranial pressure sensor 200. The intracranial pressure monitoring adapter 100 uses a biocompatible soft rubber material that can be sterilized multiple times to make a protective shell. The protective shell is shaped to resemble the skull, which not only makes it easy to wear on the head but also improves the comfort and safety of wearing it.

[0067] Optionally, the power management module 4 also includes a power switch; the power switch is mounted on a soft rubber protective housing.

[0068] Specifically, the power switch is used to turn on the power of the intracranial pressure monitoring adapter 100 so that the wireless communication module 5, the power management module 4, and the intracranial pressure sensor 200 are powered on and put into operation.

[0069] In summary, the intracranial pressure monitoring adapter provided by this embodiment of the present invention has the following advantages:

[0070] (1) The intracranial pressure monitoring adapter and the intracranial pressure sensor are used together to realize the wireless transmission of intracranial pressure information. Since the digital signal transmitted wirelessly is checked by a check code, the accuracy of the transmitted signal is guaranteed, the electromagnetic interference resistance is improved, and the problem of inaccurate and unstable signal caused by wired connection failure is overcome.

[0071] (2) Alarm indicator lights and buzzers provide alarm indications, making it convenient for medical staff to observe the patient's intracranial pressure monitoring status in a timely manner. Wireless intracranial pressure monitors can be placed at nurses' stations or doctors' on-call workstations, making it convenient for medical staff to monitor patients.
