Instruments used in pathology
Appearance
Instruments used specially in pathology are as follows: [1][2][3]
Instrument list
[edit]Instrument | Uses |
---|---|
Flow cytometer | used for automated cell counting as in total blood count, differential count, etc. |
Tissue bath or organ bath or Dale's apparatus | used in full tissue experiments, for example using guinea pig ileum mainly used in pharmacology for application of drugs to these tissues. |
Sahli Haemoglobinometer | an old but rapid and simple method of hemoglobin estimation in the laboratories. Presently used in some places where sophisticated optical instruments are not available |
Haemocytometer | a microscope associated apparatus used for manual counting of cells in body fluids like blood, etc. including for sperm count |
Wintrobe's tube | used for ESR (Wintrobe's method), PCV, haematocrit, etc. |
Westergren's tube and ESR stand | used for ESR (Westergren's method) |
Disposable plastic molds or embedding molds (Leukart's L blocks) for tissue paraffin block making w.r.t. Histopathology | used to make blocks of tissue for cutting into thin slices for microscopy |
Block holders (in histopathology) | used to hold the tissue blocks during cutting |
•Refrigerated microtome (cryostat) | -do-; a special type that is used during operations to aid the surgeon in demarcating the diseased (specially neoplasms) tissue. |
•Rocking microtome | -do-; a special type |
•Base sledge microtome | -do-; a special type |
•Ultra microtome | -do-; a special type |
Tissue section floating baths (in histopathology) | used to spread the cut thin slices onto water using surface tension from where it is placed onto glass slides |
Ryle's tube or nasogastric tube | used for nasogastric suction (or at times introduction of food or drugs). video link |
FNAC needles | used for fine needle aspiration of material from inside the body; used for diagnostic examinations of the cells hence obtained; video link |
Trephine biopsy needle[4] | used for taking a biopsy from a deep hard tissue like bone marrow (within a hard bone) |
Spirometer | used to test lung function; video link |
•Water-seal type | -do- |
•Douglas bag type | -do- |
Peak flow meter or peak expiatory flow rate meter | used to test lung function by testing the rate at which the person can exhale; useful to diagnose COPD and asthma |
Mercury or other manometers | used to measure pressure of a fluid within a cavity like the spinal canal, which is raised in certain diseases |
Electrocardiogra | |
Urinometer | Estimation of specific gravity of urine. |
Esbach's Albuminometer | Quantitative analysis of albumin in urine sample. |
