Polysomnography (PSG) Lektwòd etid dòmi

B2B an gwo polysomnography (PSG) dòmi etid lektwòd pou lannwit nan klinik dòmi laboratwa ak HSAT. Enjenieri ak 12-èdtan anti-idwojèl desicasyon, enpedans anba-5kOhm, ak fil plon ki kode koulè AASM.

These polysomnography (PSG) sleep study electrodes operate as specialized, multi-channel bio-potential sensor interfaces engineered explicitly for Level 1 in-lab nocturnal polysomnography, Type 2/3 Home Sleep Apnea Testing (HSAT), and continuous positive airway pressure (CPAP) titration protocols. Capturing synchronized microvolt electro-signals across 8 to 12 hours of uninterrupted overnight sleep presents unique electro-mechanical hurdles: patients continuously roll over, side-sleep, and press their heads into pillows, exerting severe torsional friction and mechanical shear on facial, scalp, and chin lead placements. In conventional EEG cup or tab electrodes, pillow friction pulls sensors away from the skin, while standard liquid gels dry out after 4 hours, causing capacitive impedance spikes (>20kΩ) ki fènwa achitekti dòmi microvolt (Delta vag dousman, spindles dòmi, K-konplèks, ak mouvman je rapid REM). Matris detèktè PSG entegre sa a pè yon mikwo-sputtered ajan/ajan-klori (Ag/AgCl) nwayo deteksyon ak yon 12{-èdtan ki pa -desikan, wo-viskoelastik idwojèl solid ak ultra-fleksib, AASM{12}12}kod ​​koulè plon. Nou fabrike etalaj detèktè konvèti-pare sa yo pou laboratwa dyagnostik dòmi, enstiti rechèch newoloji, ak OEM pyès ki nan konpitè polysomnograph globalman.

Fabrikasyon endistriyèl la nan elektwòd etid dòmi polisomnografi konbine wo -woulo presizyon-a-woulo (R2R) enprime ekran, milti-kondiktè fil retire rad sou ou, mikwo-rezistans rezistans / soude soude, ak distribisyon idrogel chanm pwòp. Yon optik -polyester (PET) oswa fleksib an poliyiretàn substrate web enprime ak gwo -pite ajan/ajan-klori (Ag/AgCl) lank kondiktif pou fòme yon etalaj de pisin mikwo-deteksyon. Plizyè -fil an kwiv tinsel kouvri nan TPU medikal -klas, ba-friksyon yo koupe, dezabiye, ak soude otomatikman sou tras Ag/AgCl la. Junction a overmolded ak yon ultra-mens (<1.8mm) strain-relief collar that eliminates sharp edges. An aqueous polyacrylamide hydrogel formulation plasticized with high-purity glycerin and skin-neutral electrolytes is slot-die extruded into the sensor wells. Rotary die-cutters punch out circular (22mm to 28mm) or teardrop shapes with low-profile adhesive skirts. Color-coded 1.5mm DIN 42802 touchproof sockets are injection-molded onto wire terminals in strict accordance with AASM color sequences (e.g., green/black/white for EMG, red/blue for EOG, yellow/brown for EEG). The finished multi-lead sets are card-mounted and hermetically sealed into zero-MVTR foil pouches under ISO Class 7 cleanroom controls. The minimum production run threshold is 300,000 sets.

• 12-èdtan ki pa-desikasyon jèl osmotik matris (zewo derive enpedans etap dòmi)

  Traditional sleep diagnostic procedures relying on wet collodion paste or thin conductive gels suffer from progressive overnight evaporation. As room air conditioning and patient body heat (37℃) dry out the gel after 3 to 4 hours, contact impedance spikes from 3kΩto over 30kΩ. This impedance shift destabilizes neuro-amplifier common-mode rejection (CMRR), creating baseline drift that obscures critical 0.5–2.0Hz Delta slow waves and 12–14Hz sleep spindles in N3 deep sleep. We formulate our PSG electrode with a high-osmotic polyol humectant lattice that depresses water vapor pressure. The hydrogel retains >94% nan volim likid li atravè 12 èdtan nan kontak chalè kontinyèl kò -, bloke enpedans entèfas ki pi ba a 3.5kΩ pandan tout lannwit lan anrejistreman.

   

• Ba-Pwofil Anti-Tòsyon Riban ekipay (dekouple friksyon zòrye ak woule Pasyan)

  Nan polisonnografi konplè, pasyan yo voye jete epi vire plizyè douzèn fwa chak swa. Gwo, câbles plon wonn trape sou dra kabann ak zòrye, transmèt fòs rale torsional dirèkteman nan plasman feminen ak submantal. Sa a trennen mekanik kreye zafè mouvman toudenkou, fo siyal bruxism sou chanèl Chin EMG, oswa dislodgement elektwòd ki anile nòt etid dòmi dyagnostik. Elektwòd nou yo genyen ultra-fleksib, plat-riban oswa ki lejè mikwo-tisel fil plon ki konbine avèk yon junction planè soulajman 360-degre (<1.8mm profile height). Pillow compression glides smoothly across the planar backing without twisting the wire or transmitting lifting shear to the hydrogel boundary.

   

• Sou-Etaj bri mikrovòl ak koulè strik AASM-kodaj (Senkronizasyon milti-chanèl)

  Nòt twoub dòmi konplèks (tankou REM Twoub Konpòtman dòmi ak apne dòmi santral) mande pou anrejistreman similtane nan etap dòmi EEG, mouvman bilateral EOG rapid nan je, Chin EMG misk atonia, ak mouvman anterior tibialis manm. Crosstalk ant chanèl fasyal dans oswa enstabilite elektwochimik jenere fo lekti ton nan misk. Eleman detèktè nou yo sibi fritizasyon esteyyometrik ak presizyon pou kenbe yon etaj bri debaz sub-mikwovolt (<0.4µVRMS) and a DC offset under 2.5mV. Pre-configured AASM color-coded leadwires streamline multi-channel technician hookups, preventing cross-channel wiring errors and eliminating 50/60Hz line-frequency interference across all synchronized channels.
