Description
Technical field
The present invention relates to technical field of medical instruments, and in particular to a kind of pressure limiting for splanchnocoel negative pressure drainage device fills
Put.
Background technology
Existing splanchnocoel drainage system has three kinds：
First, single-chamber drainage tube negative pressure ball, its principle be by negative pressure ball pinch it is flat after spheroid wall elastic recovery force formed it is negative
Pressure.Its advantage is easy to carry, caliber is thin, trauma of abdomi napwall is small, internal organs influence is small.But shortcoming one is that pressure is uncontrollable, too small shadow
Drainage effect is rung, it is excessive, suck nethike embrane and intestinal wall causes plugging, the intestinal obstruction even consequence such as necrosis；Second, finite capacity, draws
Need frequently to change and empty when flow is more；Third, be not configured with imitate unidirectional valve control head, when drainage liquid measure more than or by
To the possibility for having adverse current during extruding.The Chinese patent (application number 201520812916) that Authorization Notice No. is CN205163738U is public
A kind of disjunctor negative pressure ball drainage system is opened, it is connected by spherical upper end drainage ball with lower end drainage ball by unidirectional drainage valve
Composition, the device drainage flow is big, can avoid repeatedly changing drainage ball device, while can also avoid adverse current, but pressure is still not
It is controllable.
2nd, single lumen catheter wall vacuum suction, its principle are so as to producing negative pressure by connecting wall negative pressure channel.Its advantage
It is pressure adjustable section, the needs of larger negative pressure can be met, it is preferable to the attraction effect of the concentrated things such as infection or necrosis, while
More drainage-fluid can be accommodated.But its shortcoming is also very prominent, first, drainage tube is thick, quality is hard, injury of abdominal wall is big, to internal organs shadow
Sound is also big, easily oppresses intestinal tube and causes obstruction even necrosis；Second, pressure oscillation, due to lacking pressure limiting device, when local lacuna disappears
Pressure steeply rises during mistake, a series of adverse consequences, including bowel obstruction, necrosis even massive haemorrhage occurs, jeopardizes life
Life；It is difficult application when field and simple and crude condition third, extremely inconvenient using carrying.
3rd, single lumen catheter pedal negative pressure attracts, and its principle is by negative using being formed after foot-operated exhaust to fixed volume space
Pressure.Its advantage is that pressure is relatively controllable, can meet the needs of larger negative pressure, and the attraction effect to thick matter is fine, carries phase
To facility.Its shortcoming one is to need special messenger to ride, and requires high to manapower allocation；Second, although pressure can be adjusted according to foot-operated dynamics
It is whole, but dynamics is bigger than normal and is difficult to accurately control；Third, using also more inconvenience, in the wild and condition of battlefield also is difficult to apply.
Above-mentioned three kinds of splanchnocoel drainage systems can not meet to use simple and convenient, the constant controllable, drainage flow of pressure simultaneously

Operation principle：
During using the various embodiments described above, negative pressure connecting portion 2 is connected into outside negative pressure source (negative pressure by negative pressure connector 21
Source can provide larger and stable negative pressure), drainage connecting portion 3 connects drainage tube by draining connector 31, and drainage tube stretches into
In the thoracic cavity or abdominal cavity of patient.During original state, blocking first 51 and the negative pressure connected entrance of negative pressure connecting portion 2 are released state, whole
Communicated inside individual device with negative pressure source, negative pressure will be produced, when negative pressure is excessive, flexible shell 1 is by axial shrinkage, while with limit
Pressure controlling organization 5 is moved, until blocking the negative pressure connected entrance on first 51 blocking negative pressure connecting portion 2, negative pressure is not further added by.Work as thoracic cavity
Or the liquid in abdominal cavity, when gradually being sucked in the device, its internal negative pressure will diminish, and flexible shell 1 is in pressure stabilizing mechanism 4
Restoring force effect it is lower uphold, while moved with limited-voltage control mechanism 5, block first 51 negative pressure from negative pressure connecting portion 2 and connect
Port is removed.When connecting negative pressure source, pressure stabilizing mechanism 4 and limited-voltage control mechanism 5 act synergistically, and blocking first 51 can not break off a friendship
Alternately block and open negative pressure connected entrance so that the negative pressure inside device is constant, and then realizes to attracting thoracic cavity or abdominal cavity to bear
The limitation of pressure value and stably.And the vacuum magnitude inside device is related to the deformation quantity of flexible shell 1, support bar 52 connects with connecting
First 53 are spirally connected, therefore rotation support pole 52 controls the length of limited-voltage control mechanism 5.Limited-voltage control mechanism 5 is longer, blocks
First 51 amounts of contraction of flexible shell 1 when blocking negative pressure connected entrance are smaller, and internal controllable constant negative pressure is with regard to smaller；Conversely, pressure limiting
Controlling organization 5 is shorter, then the amount of contraction of flexible shell 1 will be bigger when negative pressure connected entrance is blocked in blocking first 51, internal controllable
Constant negative pressure is bigger.
In addition, pressure stabilizing mechanism 4 can also not have to spring, when flexible shell 1 itself has certain back stretch,
Flexible shell 1 can inherently function simultaneously as pressure stabilizing mechanism 4, and now the ripple tubular of preferable embodiment 1 has one
The flexible shell of fixed elasticity.
The preferred embodiment to the invention is illustrated above, but the invention is not limited to implement
Example, those skilled in the art are without prejudice to can also make a variety of equivalent modifications under precondition for innovation of the present invention or replace
Change, these equivalent modifications or replacement are all contained in the application claim limited range.
