Definitions

  • Implantable measuring unit for intra-orporal measurement of patient data
  • the invention relates to an implantable measuring unit for intracorporeal measurement of patient data, in particular intracranial pressure, for mobile use under everyday conditions and an additional application to DE 196 38 813.9 entitled "Intracorporeal measuring system”.
  • measuring probes are inserted into the body using a catheter, e.g. m inserted the head (mtrakramell) and directed to places where bio signals have to be measured.
  • a catheter e.g. m inserted the head (mtrakramell) and directed to places where bio signals have to be measured.
  • the probes When measuring in the skull, the probes must have a very small cross-section and are therefore preferably microsensors which are mounted and contacted in a carrier sleeve.
  • the intracranial pressure is measured with a mtra ran ⁇ ell probe.
  • the probe is then pulled out and destroyed or, in the case of reusable probes, sterilized and reused with the next patient.
  • a so-called shunt system is put in place, by means of which when the brain pressure rises above a fixed value brain water (liquor), the abdominal cavity is drained off so that overpressure i * -, goin is avoided.
  • the intracranial pressure measurement can be done both epi- and subdural.
  • Epidural means that between the hard meninges
  • the intracranial pressure is determined indirectly via the pressure exerted on the meninges by the iquor.
  • This measuring location has the advantages that the hard meninges are not pierced, thus avoiding an infection of the meninges, the procedure is much easier, no brain tissue is injured during this measurement, and the sensor can remain at its measuring location for a longer period of time.
  • a micro pressure sensor is attached to a metal housing. The sensor is connected to the strands of a cable through which 5 electrical signals are sent to an extracorporeal evaluation unit be directed.
  • Another epiduraies system is available from Spiegeibero, in which a balloon catheter is pushed under the C otte C. Depending on the pressure in the brain, the hard meninges on the Ballon transmits, the pressure is passed outside via a line and can be measured extracorporeally there.
  • the company Camino offers a mtravent ⁇ kulare intracranial pressure measurement system with an optical waveguide, in which a pressure measurement is carried out according to the reflection measurement method via a silicon oxide mirror, which changes its position and thus its reflection coefficient depending on the pressure.
  • the reflected portion is set in relation to the transmitted light portion, whereby information about the pressure in the ventricle is obtained.
  • the system offers the advantage of TÜV approval that no electrical currents or voltages occur mtracorporally.
  • the aforementioned measuring systems require a station e rs admission of the patient to perform pressure measurements because the leads are very sensitive. It is desirable tj edoch, m time intervals mtrakorporal Pres e t ⁇ i normal living conditions of the patient to be measured: and recorded.
  • CSF drage would be an implantable measuring system for
  • US Pat. No. 4,519,401 describes a telemetric, mtracramular pressure measurement implant that does not require any cable connections to extracorporeally located recording and evaluation units.
  • a first radio unit is provided, which transmits the measurement signals of a pressure and a temperature sensor to a second radio unit.
  • the first radio unit is implanted under the scalp and is connected to the intracorporeal sensors.
  • the patient carries the second radio unit with him extracorporeally.
  • Both radio units each have a transmitter and a receiver.
  • the sensors are activated with a pulse that is transmitted from the second radio unit to the first radio unit.
  • the measurement data are then transmitted from the first to the second radio unit and can be stored from there and displayed on a monitor.
  • the system described switches the sensors on and off at preset intervals. Then it can happen that suddenly increasing pressures are recorded. In addition, the recording of the measurement data is constant regardless of the relevance of the data. It is not possible to obtain a continuous measurement signal because the data rate of the measured values ZL is low.
  • the use of radio signals requires relatively large transmission powers in the vicinity of the brain, which may have harmful side effects.
  • the German published patent application DE 43 41 903 AI describes an implantable telemetric endosystem, the external dimensions of which are smaller than 1.0 mm x 1.5 mm x 0.6 mm.
  • the implantable measuring system has a sensor connected to a telemetry unit which is inductively coupled to an extracorporeal receiving device.
  • the implanted system is inductively supplied with energy from the outside, so that no batteries have to be implanted.
  • Amplitude, frequency and pulse width modulation are proposed as data transmission methods. A method for arranging, fastening and wiring the pressure sensor and the telemetry unit is not described.
  • the telemetry unit should now be used for trouble-free and patient-friendly operation directly under the skin of pressure / temperature sensor and telemetry unit on a chip is not advantageous, ⁇ a dei sensor must be inserted at defined points in the body, eg in the cerebrospinal fluid under the meninges therefore a separation of sensor and telemetry unit is required.
  • the conventional systems use a cable connection between the sensor and the transmission unit, e.g. Telemetry unit.
  • the cable connections can only be implemented in a very complex and error-prone manner.
  • the implantation by the doctor requires a lot of skill, since the cables cannot be pushed under the skin and can twist and break during the implantation.
  • Invention to provide a measuring unit with an implant part for mobile use for measuring the intracranial pressure with a simple and inexpensive to attach and connect sensor and telemetry unit.
  • the measuring unit should be implantable by the doctor simply and without complications.
  • the wiring of the sensor element and the telemetry device with conductor tracks can be implemented inexpensively and reliably.
  • the flexible film is very easy to implant because it can be pushed under the skin without twisting or undesirably changing direction. This allows the ocr with a smaller diameter than usual.
  • FIG. 1 shows a top view of the implantable measuring system
  • Fig. 2 Cross section through the implantable measuring system
  • Fig. 3 Mobile measuring unit for extracorporeal data transmission and evaluation.
  • a new type of brain pressure measurement system is presented as a preferred embodiment. Likewise, the measuring system can also be used for other medical applications.
  • FIG. 1 a schematic view of the implantable part of the measuring system that is represented t Eir sensor element 1 with at least one sensor, for example, for printing, is implanted.
  • other sensors for example for temperature, can be provided as required.
  • the sensor element 1 is ver with a telemetry unit 2 b Andes, ie, implanted with an inductive coupling element, the eoen AIIS.
  • the telemetry unit 2 has supplied a power ä ußere coil through which the implanted circuit mt inductive.
  • the data measured in sensor element 1 are transmitted with an inductive coupling ar to an evaluation unit. Thereby, it is no t h r me necessary to implant a battery.
  • the sensor element 1 and the telemetry unit 2 are applied to a flexible film 3 which has conductor tracks 4 for the electrical connection of the sensor element 1 and the telemetry unit 2.
  • the flexible film 3 is very easy to implant because it can be pushed under the skin without twisting or undesirably changing direction. As a result, the hole to be drilled in the skullcap can be designed with a smaller diameter than previously customary.
  • only a very small incision is required in the skin, since the film 3 with the sensor element 1 and the telemetry unit 2 applied thereon is very narrow.
  • the implantable measuring unit is shown in cross section in FIG. It can be seen that the sensor element 1 and the telemetry unit 2 m of a special design are arranged on opposite sides of the film 3. There is provided a through-l augmentation 5 for the conductor track 4 to guide it to the opposite side.

Abstract

Unité de mesure implantable pour mesurer à l'intérieur du corps des données d'un patient, notamment des pressions intracrâniennes, pour un usage mobile quotidien. L'invention est une demande d'addition à DE 196 38 813.9. Habituellement, les unités implantables présentent une liaison par câble entre le détecteur et l'unité de transmission. Ces liaisons par câble sont très complexes à réaliser et sujettes aux erreurs. En outre, l'implantation par le médecin exige beaucoup d'adresse car les câbles ne peuvent pas coulisser sous la peau et risquent de se tordre et de se briser lors de l'implantation. L'élément détecteur (1) et l'unité de télémesure (2) sont placés sur une feuille flexible (3) qui comporte les tracés conducteurs (4) pour la connexion électrique de l'élément détecteur (1) et de l'unité de télémesure (2). L'unité de mesure est destinée à un usage médical, principalement pour mesurer la pression intracrânienne.
