Description

Technical Field

[0001] The invention belongs to the field of medical devices and relates to a cochlear implant pressure detection device and method. Background Art

[0002] As we all know, inductive coupling technology is widely used in implantable medical devices. This technology can perform functions such as signal transmission and wireless charging. In particular, for electronic implantable medical devices, this technology makes the implant no longer need batteries, but completely rely on external components for power supply, which can greatly improve the service life of the implant.

[0003] In actual application, the thickness of the skin flap varies greatly among users of medical devices depending on their age, weight and gender. This makes it difficult to control the magnetic attraction between the external transmission coil of the cochlear implant and the receiving coil of the implant. If the magnetic attraction is small, the transmission coil will easily fall off; if the magnetic attraction is large, the pressed skin will easily become red, swollen, inflamed, or even ulcerated.

The upper airbag coat and the lower airbag coat are connected by several non-closed concentric circular rings to form a ventilation cavity.

[0007] Preferably, the upper bladder casing is connected to the lower bladder casing by an adhesive.

[0012] Based on the above purpose, the present invention also provides a cochlear implant pressure detection method, using the above cochlear implant pressure detection device, comprising the following steps:

[0014] S20, the body inflates the airbag through the catheter to a first pressure;

[0015] S30, the air pressure sensor detects the degree of compression of the gas in the airbag and displays it on the display screen;

There is no need for a varistor or an inductive coupling circuit to sense the pressure or distance between the transmission coil and the receiving coil. The pressure can be detected more accurately only by the air pressure sensor.

[0029] Device Embodiment

[0030] See also Figure 1-4 , shown is a cochlear implant pressure detection device of the present invention, comprising a body and an air bag 30, wherein:

[0031] The body is connected to the airbag 30 through the catheter 7. The body includes an upper shell 16, a button 18, a catheter joint 8, a screw joint 9, a display screen 10, a battery 11, a waterproof ring 12, an air duct 14, an air pressure sensor 15 and a lower shell 13. The button 18 and the display screen 10 are exposed from the upper shell 16. The catheter joint 8, the screw joint 9, the battery 11, the waterproof ring 12, the air duct 14 and the air pressure sensor 15 are arranged in a space formed by the upper shell 16 and the lower shell 13 being covered or buckled. The catheter joint 8, the screw joint 9, the air duct 14 and the air pressure sensor 15 are connected in sequence. The waterproof ring 12 is sleeved between the air duct 14 and the screw joint 9. The catheter 7 is connected to the catheter joint 8;

[0032] The airbag 30 is connected to the catheter 7 through a sealing joint 6. The airbag 30 includes an upper airbag coat 31 and a lower airbag coat 32. The upper airbag coat 31 and the lower airbag coat 32 are both circular, with a diameter not less than the diameter of the external transmission coil 2 of the cochlear implant. The upper airbag coat 31 and the lower airbag coat 32 are connected by a number of non-closed concentric circular rings to form a ventilation cavity 33.

[0033] In a specific embodiment

[0034] During pressure detection, the airbag 30 is located below the external transmission coil 2 of the cochlear implant, between the external transmission coil 2 of the cochlear implant and the implant receiving coil 1, and on the skin 17. The button 18 adjusts the air pressure output to the airbag 30 through the catheter 7, and can increase, decrease, reset, pause and count. Since the device does not require high precision for the detection of pressure or pressure intensity, it can be detected multiple times to improve accuracy and better provide data support for the subsequent adjustment of the magnetic suction force in the transmission coil 2. The upper capsule 31 and the lower capsule 32 are made of silicone or PVC material, and the upper capsule 31 and the lower capsule 32 are connected by adhesive or ultrasonic welding or high frequency welding or UV light welding. All can achieve a better connection and fixing effect.

[0035] The sealing joint 6 is of pagoda type and is connected to the conduit 7 to prevent air leakage.

[0036] Based on the above purpose, the present invention also provides a cochlear implant pressure detection method, using the above cochlear implant pressure detection device, comprising the following steps:

[0037] S10, when the cochlear implant system is in use, the airbag 30 is placed under the transmission coil 2 of the cochlear implant external device, and the device is turned on;

[0038] S20, the body inflates the airbag 30 through the catheter 7 to a first-level pressure;

[0039] S30, the air pressure sensor 15 detects the degree of compression of the gas in the airbag 30 and displays it on the display screen 10;

[0040] S40, if the transmission coil 2 of the cochlear implant external device has not fallen off, the body inflates the airbag 30 through the catheter 7 to a secondary pressure;

[0041] S50, the air pressure sensor 15 detects the degree of compression of the gas in the airbag 30 and displays it on the display screen 10;

[0042] S60, if the transmission coil 2 of the cochlear implant external device has not fallen off, or the squeezing degree detected by the air pressure sensor 15 exceeds the threshold, it indicates that the pressure exceeds the standard and the magnetic strength in the cochlear implant needs to be reduced.

[0043] The first level pressure is 1.3-1.5 atm. Under this pressure, the pressure detected by the air pressure sensor 15 is greater than 5N or the pressure is greater than 0.4N / cm 2 (After the air pressure sensor 15 detects the air pressure, it can convert the pressure intensity through the circuit), then the magnetic attraction in the transmission coil 2 is too large and needs to be replaced with a smaller magnet.

[0044] The secondary pressure is 1.5-1.7 atm. Under this pressure, the pressure detected by the air pressure sensor 15 is greater than 3N or the pressure is greater than 0.3N / cm 2, then the magnet attraction in the transmission coil 2 is too strong and needs to be replaced with a smaller magnet.

[0045] The thickness of the airbag 30 after inflation is 1mm-2mm. If the transmission coil 2 still does not fall off after being inflated to 2mm, it indicates that the magnet in the transmission coil 2 has too strong suction force and needs to be replaced with a magnet at least two sizes smaller.

[0046] The present invention does not require additional circuit design in the cochlear implant system, and the pressure detection of the transmission coil 2 on the human skin when in use does not need to be precise. It only needs the pressure or pressure to be within the threshold value. Therefore, an ingeniously structured airbag 30 is designed to cooperate with the air pressure sensor 15, combined with related circuits, display screen 10 and buttons 18, etc., to achieve pressure or pressure detection.

[0047] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
