Abstract
The utility model relates to the technical field of medical instruments, particularly to a surgical dual-cavity tube integrating washing with negative-pressure suction regulation. The tube comprises a dual cavity tube (1), a negative pressure regulation valve (2) and a washing fluid control valve (3), wherein the negative pressure regulation valve is mounted on a suction tube (1.1) on one side of the dual-cavity tube, the washing fluid control valve (1.2) is mounted on a washing tube (1.2) on the other side, a button (2.1) on the negative pressure regulation valve (2) can be used for adjusting the negative pressure of the internal cavity of the suction pipe, and then blood or other fluid beyond the visual operation field can be sucked and removed; and the opening or the closing of the washing tube can be controlled by regulating the washing fluid control valve (3). The dual-cavity tube has the advantages as follows: the structure is simple and the cost is low; since the negative pressure regulation valve and the washing fluid control valve are arranged in an adjacent but stagger manner, an operator just needs to operate two valves with one hand respectively; the operation is simple, timesaving and laborsaving, and the smooth advancement of operation and the improvement on operation quality are facilitated.
Description
Technical field
This utility model relates to technical field of medical instruments, is a kind of the operation with having the double lumen tube of flushing with the vacuum suction regulatory function concurrently.
Background technology
In the surgical procedures, often blood or other body fluid because of place, art open country causes the visual field unclear, needs in time to absorb blood or other body fluid, absorbs after the flushing of cooperation flushing liquor again, can make the visual field more clear.At present, what use when absorbing blood or other liquid is the suction catheter that links to each other with negative pressure ventilation equipment such as negative pressure pump or operating room attraction pipeline, establish a pore on the suction catheter tube wall, when absorbing liquid, with finger pore is blocked, negative pressure ventilation equipment is bled and is produced negative pressure liquid is absorbed by suction catheter, pore is decontroled to stop to attract then.The shortcoming of this suction catheter is to regulate and control the size of negative pressure, so that negative pressure may hold tissue when excessive and cause tissue injury, especially as cracky tissues such as liver,spleen,kidneys, but also influences the operation progress because of the shutoff of getting rid of the mouth of pipe.Flushing to the Rhizoma Atractylodis Macrocephalae open country, usually flushing liquor is directly toppled over bowl, cup-like containers, this just makes, and flush operation is wild can not be operated by same people with the absorption flushing liquor, and two people's compounding practices tend to flushing liquor can not be poured on the target art open country quickly and accurately, also can influence operation progress and quality.
Summary of the invention
The purpose of this utility model provide flush operation in a kind of operation process wild and absorb flushing liquor can be by the double lumen tube that has flushing and vacuum suction regulatory function concurrently of same people's operation.
This utility model is made up of double lumen tube, negative pressure control valve and flushing liquor control valve, double lumen tube one side is a suction catheter, opposite side is a syringe pipe, suction catheter is thick than syringe pipe, double lumen tube divides head, body and afterbody three parts, and two tube heads flush, and afterbody is Y shape bifurcated, so that suction catheter tail end and negative pressure ventilation equipment are joined, the syringe pipe tail end links to each other with the flushing liquor transfusion device.Near on the tube wall of afterbody one end, suction catheter is provided with negative pressure and regulates valve opening at the double lumen tube body, and this place, place, hole is double-layer tube wall, internal layer is an elastica, firmly be attached at the suction catheter tube wall around this elastica, central authorities are provided with circular hole, and this circular hole is consistent with the negative pressure adjusting valve opening orientation of outer wall; Regulate on the syringe pipe tube wall of the not far other direction (as vertical direction) of valve opening in contiguous suction catheter negative pressure, be provided with flushing liquor control valve opening, this place, place, hole also is a double-layer tube wall, and internal layer is an elastica, firmly is attached at the syringe pipe tube wall around the elastica.The negative pressure control valve is made up of button and spring, button is made by hard material, be the asymmetric dumbbell shaped of hollow, be that the hollow circular cylinder two ends are respectively the disk that diameter does not wait, disk central authorities are equipped with circular hole, Circularhole diameter equates that with the hollow circuit cylinder intracoelomic cavity external diameter of roundel is regulated valve opening greater than negative pressure; Spring is placed in outside the hollow circular cylinder.When the negative pressure control valve is installed on the negative pressure adjusting valve opening of suction catheter, the roundel of button places between the interlayer of this place's double-layer tube wall, spring is between the outer wall of big disk and suction catheter, the circular hole of elastica central authorities communicates with the circular hole of button central authorities, because due to the elastic force of spring and elastica, under the situation of no external force, elastica relies on the outer wall of suction catheter, button is outside by bullet, if this moment, the suction catheter tail end was bled, and negative pressure minimum in the pipe, negative pressure maximum when finger is pinned the button central circular hole, under the situation of not sealing central circular hole, when the button pressurized was pressed gradually, elastica was stretched to expand and moves towards the opposite tube wall, the suction catheter inner chamber narrows down, negative pressure diminishes gradually in the pipe, and blood or other liquid are absorbed, and just can not occur tissue is held the phenomenon that causes tissue injury as long as control button well.The flushing liquor control valve is by the regulation and control bolt, stick, control lever bracket and spring are formed, stick is fixed in the syringe pipe outer wall by control lever bracket, the regulation and control bolt is positioned at the stick head, it inserts and withstands elastica by flushing liquor control valve opening set on the syringe pipe tube wall, spring places between stick afterbody and the syringe pipe outer wall, under the effect of stick tail springs elastic force, the regulation and control bolt that is fixed in the stick head stretches elastica and is expanded to the opposite tube wall, syringe pipe gets clogged, during stick afterbody pressurized, the regulation and control bolt is pulled outwardly, the elastica retraction, syringe pipe is unlocked, and flushing liquor just can be flowed into by the transfusion device of syringe pipe tail end and flow out from the syringe pipe mouth of pipe.
During use, routinely the double lumen tube head is placed surgical field of view, the suction catheter tail end is connected with negative pressure ventilation equipment, the syringe pipe tail end is connected with transfusion device, can discharge flushing liquor by the flushing liquor control valve in good time, regulate the attraction vacuum magnitude by negative pressure control valve button and absorb blood or flushing liquor at any time.The dislocation because the negative pressure control valve is adjacent with the flushing liquor control valve, so the operator only needs to handle two valves respectively on the other hand and gets final product.This utility model has not only been saved manpower, and because the double lumen tube head places surgical field of view, flushing liquor directly waters the wild place of Rhizoma Atractylodis Macrocephalae, and can absorb blood or flushing liquor at any time, makes operation become convenient.
This utility model is simple in structure, and is with low cost, easy to operate, time saving and energy saving, and what help performing the operation carries out and the raising of the quality of performing the operation smoothly.
