Problems solved by technology

The above method uses passive passive RF. The disadvantage is that the internal part has no power supply and cannot actively send signals. The communication between the external part and the internal part needs to be very close, and must be one-to-one communication.

Embodiment 1

[0052] Such as image 3 As shown, the implantable wireless intracranial pressure automatic monitoring system of the present invention includes a dedicated control device and more than one implantable pressure sensor assembly, and the implantable pressure sensor assembly is partially implanted in the monitored person's In the cranium, the dedicated control device communicates and transmits data with the implanted pressure sensor assembly wirelessly.

[0053] Such as figure 2 As shown, the implantable pressure sensor assembly further includes a wireless transmission control terminal 6, a flexible hose 10 connected to the wireless transmission control terminal 6 and an implant segment 7 connected to the flexible hose 10, the The end of the implant segment 7 is provided with a pressure sensor 9, the pressure sensor 9 is connected to the wireless transmission control terminal 6 through a data line 8, and the data line 8 is passed through the flexible hose 10 and the implanted in...

Embodiment 2

[0060] The only difference from Embodiment 1 is that in the implantable wireless intracranial pressure automatic monitoring system of the present invention, there is one dedicated control device, and there may be multiple implantable pressure sensor components. An implantable pressure sensor assembly is respectively implanted into the craniums of multiple monitored persons.

[0061] Such as Figure 7 As shown, the present invention also discloses an implantable wireless intracranial pressure automatic monitoring method, comprising the following steps:

[0062] (1) The special control equipment starts to operate, and inquires the wireless signals of each implanted pressure sensor assembly in sequence;

[0063] (2) The implantable pressure sensor component starts to operate, detects the intracranial pressure value, and sends wireless signals to the outside of the body;

[0064] (3) Dedicated control equipment judges whether the intracranial pressure value is normal, and if not...

Abstract

The invention discloses an implantable wireless intracranial pressure automatic monitoring system which comprises special control equipment and an implantable pressure sensor assembly, wherein a part of the implantable pressure sensor assembly is implanted into a cranium of a monitored person; the special control equipment is in wireless communication and data transmission with the implantable pressure sensor assembly; the implantable pressure sensor assembly further comprises a wireless transmission control end, a flexible hose and an implanted section, the flexible hose is connected with the wireless transmission control end, the implanted section is connected with the flexible hose, and a pressure sensor is arranged on the end of the implanted section and is connected with the wireless transmission control end through a data line which penetrates in the flexible hose and the implanted section. According to the implantable wireless intracranial pressure automatic monitoring system, intracranial pressure can be conveniently and effectively monitored, and the intracranial pressure of a plurality of monitored persons can be simultaneously monitored in a one-to-many mode by adopting WIFI, bluetooth or other nonstandard wireless modes.

Description

technical field [0001] The invention relates to a medical device, in particular to an implanted wireless intracranial pressure automatic monitoring system. The invention also relates to an implanted wireless intracranial pressure automatic monitoring method. Background technique [0002] Intracranial pressure (ICP) is the pressure within the skull and reflects the pressure experienced by brain tissue. The body has various mechanisms by which to keep the ICP stable, in particular to control CSF pressure through the production and absorption of cerebrospinal fluid (CSF). ICP is measured in millimeters of mercury (mmHg) and is normally 7-15 mmHg for a supine adult at rest, but becomes negative (mean -10 mmHg) in the vertical position. Changes in ICP are due to volumetric changes in one or more components contained in the skull. [0003] One of the most damaging aspects of brain trauma and other head injuries is elevated ICP. Increased ICP (most commonly due to head trauma l...
