Description
Technical field
The present invention relates to the field of medical instrument technology, specially a kind of gravity pneumatic fluid loader.
Background technology
Patient cannot normally feed, and the normal nutrition needs for needing dietary intake to sustain life,
Generally patient is assisted to feed by being inserted into nasal feeding stomach tube or nasal feeding gastric tube, now there are three types of connect nasal feeding in the market
Stomach tube or nasal feeding gastric tube assist patient's feeding device：1. nasal feeding slop bag, a little class devices are changed with external wheel instills stream
Body caliber instills speed, disadvantage to reach control：Fluid instill during with obstruction, particulate matter in fluid it is much it is small not with,
Large particle is blocked by stenosis, and fluid, which instills, to be stopped；2. automation fluid injects machine, with constant speed, constant speed is pumped into, and is lacked
Point：Mechanical higher price, constant speed quantitative input is constant, and if intragastric pressure increases, machinery continues to be pumped into, and can cause to spit and vomit, and causes
Aspiration pneumonia etc.；3. personnel are pushed into food using large syringe, human resources consumption is larger, and the short time, quickly push-in was a large amount of
Food can cause：Acute gastric dilatation, until vomiting, aspiration pneumonia, 24 hourly amounts of artificial push-in are less, and most patients seek
It supports bad；Three of the above, disadvantage is apparent, cannot meet cannot voluntarily normal fed patients living needs, for this purpose, it is proposed that
A kind of gravity pneumatic fluid loader.
Invention content
It is mentioned above in the background art to solve the purpose of the present invention is to provide a kind of gravity pneumatic fluid loader
Problem.
To achieve the above object, the present invention provides the following technical solutions：A kind of gravity pneumatic fluid loader, including sealing
The bottom end of tube body, sealed shell of tank is connected with sealing cover, and speed-regulating switch, the outer wall bottom of sealing cover are equipped at the top of the outer wall of sealing cover
Governor is observed equipped with integrated sealing, the bottom end of sealing cover is connected with fluid conduit systems, and the other end of fluid conduit systems is connected with note
Liquid mouth.
Preferably, speed-regulating switch includes adjusting rod, and the top of adjusting rod, which is equipped with, shakes hands, and the outer wall of adjusting rod is close equipped with two groups
The bottom end of seal, adjusting rod is connected with adjusting bolt.
Preferably, speed-regulating switch further includes protective shell, and the bottom end of protective shell is connected with sealing cover.
Preferably, adjusting bolt is located in protective shell, and adjusting bolt is spirally connected with sealing cover.
Preferably, the intracavity bottom of protective shell offers gas grooves, and gas grooves are connected with sealing cover.
Preferably, sealing ring described in two groups is connected with protective shell.
Compared with prior art, the beneficial effects of the invention are as follows：
1. market fluid input bag, speed-regulating switch is that speed governing idler wheel is installed at outside fluid downlink conduit, to adjust rolling
The outer wall pressure to fluid conduit systems is taken turns, the internal diameter of fluid conduit systems is changed, to complete governing speed, fluid-blocking position is common interior
Diameter narrow positions, downward fluid conduit of the present invention are open unimpeded, and the outside of fluid conduit systems, which is not installed, can change fluid and lead
The device of bore, to solve obstructing problem；
2. after fluid reaches liquid injecting mouth by fluid conduit systems, liquid injecting mouth connection nasal feeding stomach tube fluid enters nose by liquid injecting mouth
It raises in stomach tube, is slowly dropped into stomach, automation fluid injection machine on the market needs first to adjust in fluid input process
The injection rate for trying automation has certain technology requirement, and after adjusting injection rate, machinery is injected with setting speed, the present invention
With fluid its own gravity for lower action edge, by adjusting speed-regulating switch, control controls downward fluid into the air of sealed shell of tank
Instillation speed, when fluid instillation terminates, the downstream pressure of gravity is less than intragastric pressure, and fluid oneself stops, avoiding air into
The occurrence of entering the abdominal distension in stomach, the present invention instill power by downlink of fluid gravity, and injection and instillation speed pass through entrance
The air capacity and speed of sealed shell of tank, which are adjusted, to be completed, and fluid downstream pressure is smaller than automation fluid injection machine injection pressure,
Such as there is gastric retention table during fluid instills and be more than fluid gravity downstream pressure, fluid is when pressure difference occurs, cannot drip
Enter in stomach, to avoid continuing to instill fluid because intragastric pressure increases, the acute gastric dilatation of initiation is vomitted, and is reduced and is inhaled
The generation of entering property pneumonia；
3. the present invention is because of above a variety of advantages, what slowly input ensured total fluid in 24 hours enters amount, is effectively improved because seeking
Malnutritive caused by insufficiency of intake, the diseases such as electrolyte disturbance are supported, largely avoided because conventional bag blocks, automation input
Rear journey occur complication the case where.
