PHYSIOLOGICAL APPARATUS Daos, Czarina 2GPH

BAT T ERY •-source of current •-Binding Posts (- & +) – where connecting wires are attached •Types of Current: 1. Direct/ Galvanic/ Constant 2. Induced/ Faradic/ Pulsating •Types of battery: 1. Dry 2. wet

S IMPLE

KEY

•switch •-Binding Posts (- & +) – where connecting wires are attached •Types : 1. New simple key-uses metal or fibre glass as its base 2. Old simple key-uses wood as its base •Parts: 1. Binding posts– where connecting wires are attached 2. metal- produces the make or brake current

KY MOGRAP H

•Apparatus for recording a) Physiological function (muscle contraction) b) Daily Temperature changes c) Variations in water level •Types : 1. Spring driven kymograph 2. Electrically driven kymograph •Parts: a) Drum b) Shaft c) Plunger d) Base e) Kymograph paper

SPRING DRIV EN KY MOGRAP H

•Smoke writing •Control: Variable Sized Fan (smaller fan= faster) •Because there is lesser air resistance to encounter •Smokey flame: kerosene/ gum camphor •Properly smoked are evenly and thinly covered w/ soot •Fixative used: Shellac

ELECT RICALLY DRIV EN KY MOGRAP H

•Preferred for long recording time anticipated •Control: Five motor control gear shift •More desirable •Because it runs continuously and does not Require rewinding

KYMOGRAPH PAPER

•The exposed portion of the paper is the glazed portion •Its edges must be overlapping opposite on the direction of its turn

INDUCTORIUM

•For controlling/ regulating the amt. of current that flows in the circuit •Types: a) Long Inductorium b) Short/ Square Inductorium • BOTH possessing 5 binding posts (3 Primary & 2 secondary)

ELECT RIC ST IMULATOR/ ELECT RIC CONV ERT ER •Alternative source of current •Current can be adjusted (3V12V) •Pre-setting to 9 NO ELETRICUTION •Used in place of: 1) Battery 2) Simple key 3) Inductorium NEVER let both ends to touch, it can cause a short circuit

S IGNAL MAGNET

•Event marker •Records the time in seconds and the type of stimulus applied •Parts a) Electromagnet b) Writing pen c) Binding posts •Types: a) New b) Old

OLD SIGNAL MAGNET •Has 2 binding posts at the top

NEW SIGANL MAGNET

•2 binding posts at its end part

2 Binding Posts

MUSCLE LE V ER

•Records the contraction of the muscle nd •2 circuit •Types: a) Old b) New

OLD MUSCLE LE V ER •After loading screwcontrols the direction/ position of the writing pen •Writing pen- is made of hard parchment paper •Binding post is at the side

Writing Pen

After loading screw

NEW MUSCLE LE V ER

•Has 2 binding posts •Has 2 holes: 1) Before the bp – where the writing pen’s holder is attached 2) After the bp- where a strong thread/ wire is attached to the gastrocrenious muscle

MUSCLE CLAMP •Used to hold the muscle in place •Has a bp Muscle contracts

Muscle relaxes

T UNING F ORK •Records the time duration of muscle contraction •Creates 100 vibration/ second •Writing pen is attached to one of the prongs NOT an ELECTRICAL apparatus

PNEUMOGRAP H & TAMBOUR

•Records the changes in the size of an object (i.e rib cage/ thoracic cage)

PNEUMOGRAP H

•Rubber pleated tube & •Chain/ metal chain

TAMBOUR •Bowl – shallow depression inside •Rubber sheet- covers the bowl; made up of Latex (a) (a) •Tight fitting ring- secures (b) the rubber sheet (b)

RUBBER MALLET/ REF LEX HAMMER

•To study experiments on reflexes •To test the integrity of the spinal cord in the lower back region The (Pointed) end part hidden Is used for checking sensitivity

Used in the ts

ST ET HOSCOPE

EARPIECE

•Ear piece •Rubber tube connector •Chest pieces: 1) Shallow bell- with the depression; detecting low frequency sounds 2) Stiff diaphragm- detects the high frequency sounds

RUBBER TUBE

Shallow Bell Stiff diaphragm

SP HYGMOMANOMET ER •Measure the Blood Pressure (110-120/ 80) •Types: 1. Mercurial sphygmomanometer 2. Aneroid sphygmomanometer 3. Digital sphygmomanometer

MERCURIAL

SPHYGMOMANOMET ER

•MOST RELIABLE •Phased out due to the mercury content (very hard to store & dispose) •Mercury chamber /cylinder •Aspirator •Pressure cuff/ rubber cuff (ante cubital fossa)

ANEROID SPHYGMOMANOMET ER •VERY SENSITIVE •Uses Dial

DIGITAL SP HYGMOMANOMET ER

•Too Expensive •Unreliable

SP Y ROMET ER

•Records diff. pulmonary vol & capacity •Calibration: up to 6 L( 100mL or 0.1L) •Recording in mL •Drum- placed inverted position in water
