Description
Technical field
The utility model relates to dual-use the field of medical instrument technology, in particular to a kind of effect support formula Portable field weighing apparatus
Negative pressure suction device.
Background technique
In regular medical place, vacuum suction by central negative pressure center of attraction generate negative-pressure ward effect suction sputum,
Attract wound bleeding and other secretion exudates.Due to being central negative pressure, equipment investment is big, it is desirable that and it is high, such as: vacuum attraction
It stands generally by two water-ring vacuum pumps, a vacuum tank, solenoid valve, moisture separator, electric appliance control box, connecting pipe, butterfly
The composition such as valve and shut-off valve, they, which are installed in, attracts in pump house.Attraction pipeline: general pipeline and branched pipe use galvanized pipe, enter
It behind ward, using copper tube, is fixed on package cover, and is connected with gas terminal valve (gas head).Gas end connects
Connector (plug-in quick coupling): being usually in sealing state, and when being inserted into suction bottle, gas end is automatically opened, and generates negative
Pressure.Aspirator (bottle) belongs to autonomous device, and volume is 1-5 liter, when in use, suction bottle is inserted into corresponding jack mouth, so that it may make
Negative pressure is generated in bottle, so that dirt in patient body smoothly be sucked out.Vacuum meter indicated value on vacuum pump, to adjust after being installed
It is advisable in -0.03Mpa to -0.07Mpa range, this can satisfy ward requirement.When indicated value is lower than -0.03Mpa,
Vacuum pump starts pumping automatically, is automatically stopped pumping as pointer arrival -0.07Mpa.Electromagnetism is installed on the admission line of pump
When valve, solenoid valve and pump motor synchronous averaging, i.e. electric motor starting, solenoid valve is automatically opened to be connected with vacuum system；When pump machine is stopped
When only working, solenoid valve is automatically closed, and water and air backflows into vacuum system when preventing termination of pumping.Also, system uses
Two water-ring vacuum pumps alternate use；That is latter pump of power turn-on works first, reach certain negative pressure value (-
0.07Mpa) pump trip afterwards, when the negative pressure of vacuum system rises to -0.03Mpa, another vacuum pump starts automatically, in this way
It is maintained at system in the vacuum range of setting in cycles.This is the infrastructure device of central hospital, and this negative pressure equipment compares
It generally uses, acquired data -0.03Mpa to -0.07Mpa range is big data as a result, clinically being inhaled using the negative pressure
Lead device has been applied in patient 10,000,000,000 times or more.Easy electric suction apparatus is usually used in medical aid station, volume is relatively
Greatly, not readily portable, field work operation is more complicated.
Currently, existing manual or foot control suction device is due to attracting negative pressure pressure not reach requirement, leak rate is high, cannot
The attraction requirement for meeting field is not suitable for air flue internal haemorrhage caused by the battlefield upper breast perforating wound in field or hematocele, drowns
Required when water or family old man expectoration inability, auxiliary suction device, existing Portable vacuum suction device can only solve
Oral cavity blood, sputum or secretion cleaning not can solve deep nasal cavity, pharyngeal cavity, trachea-bronchial epithelial cell, stomach blood, sputum or divide
Secretion cleaning.
In addition, carry or give emergency treatment to a patient into primary scene or in rescue of battlefield or when the wounded, the carrying of aspirator
It is inconvenient, it is complicated for operation.Studies have shown that foreign bodies in airway, blood, sputum or secretion blocking air flue cause patient or the wounded to stop up
The dead incidence of breath is 15.7%.In field operation battlefield and training place, Airway damage, wound bleeding needs to be suitable for the suction in field
Leading-in device.Especially the elderly, cough reflex ability is poor, expectoration is powerless, Airway secretion occurs in family or far from medical space
Object or sputum blood blocking air flue incidence are high, be easy to cause perinatal asphyxia, hypoxic encephalopathy, dead, family purchases disposably
Sputum aspirator and its it is necessary to.In case of emergency time is longer there is sputum aspirator in hospital, if by bed or first aid
Case prepares the disposable suction device of operation conveniently, can win further rescue machine meeting.The personnel of drowning are existing in field first
Field relief, the interior water sucked of air flue stomach function regulating is relatively more, is equally also required to be suitable for the suction device in field.
Therefore, how a kind of effect support formula Portable field weighing apparatus negative pressure suction device is provided, can satisfy in stable negative pressure
Suction pressure is in -0.03Mpa to -0.07Mpa range, and the computable negative pressure range is -0.3099kgf/cm2To-
0.702kgf/cm2, while easy to carry, easy to operate, it has also become the technical issues of those skilled in the art's urgent need to resolve.

The negative pressure suction device that weighs maintains the minimum sectional area of one inner passage of negative-pressure suction pipe restriction of permanent negative pressure, but due to sputum
Density is non-constant in test, therefore using castor oil as experimental study disjunction mark, the viscosity of castor oil is relatively high, with sputum and
The viscosity of blood has similitude.
A kind of effect support formula Portable field weighing apparatus negative pressure suction device is when pressure change is not too big, it is assumed that density can be close
It is seemingly seen as basic standard of the gas flowing of constant as stability study, it can to two section column energy equations in pipeline
: P1-P2=(λ L/r) V2/ (2g)；
Can therefrom flow velocity be obtained: V=√ [2gr (P1-P2)/λ L]；
Flow: Q=(π r2/4) V=(π r2/4) * √ [2gr (P1-P2)/λ L]；
In formula: V velocity in pipes；Q pipeline flow；G acceleration of gravity；R bore；P1 pipeline origin or beginning pressure；P2 pipeline is not
Side pressure is strong；λ duct wall resistance coefficient；L duct length.By calculating r bore, while generating and bearing when changing negative pressure suction ball
Pressure meets the change for leading intraductal pressure, meets and generates pressure difference, that is, P1-P2, that is, meets the attraction flow velocity of unit time, r bore is just
It is a kind of one of the basis of effect support formula Portable field weighing apparatus negative pressure suction device perseverance negative pressure.
