Abstract
The utility model provides a kind of ruminant tumor gastric fistula, the elastomeric flexible rumen fistula structure, fistula set including integral type and the hard spiral plug for closing fistula set.Rumen fistula structure includes the hollow gastric fistula tube body that middle part is arranged towards two side direction caliber flarings, external butterfly unit in the top opening of gastric fistula tube body, internal butterfly unit on the bottom opening of gastric fistula tube body, the intrados of external butterfly unit and internal butterfly unit is oppositely arranged, and the inner arc opening diameter of external butterfly unit is less than the inner arc opening diameter setting of internal butterfly unit.The elastomeric flexible rumen fistula structure of integral type makes animal rumens fistula be convenient to mount and dismount, is time saving and energy saving.The angle of middle part towards hollow gastric fistula tube body and internal butterfly unit that two side direction caliber flarings are arranged increases, so that the extruding curvature in operation fixing body when butterfly unit is bigger, therefore the operation opening outside cud wall is smaller, and leakproofness is also more preferable.
Description
Technical field
The utility model belongs to herding medical experiment instrument field, in particular to a kind of ruminant tumor gastric fistula.
Background technique
By checking cow rumen liquid, and changed according to Rumen Internal Environment, can tentatively be judged some because of cud
The cow disease that micropopulation obstacle causes.To because and on the basis of symptomatic treatment, be aided with the rumen content therapy of science,
Satisfied effect can then be obtained.
Currently, internal clamping disk is fixedly connected animal rumens fistula on the market with gastric fistula tube body mostly, it is external to clamp
Disk is the external side dismantling connection of the formula that screws togather or bolt type and gastric fistula tube body, that is, first passes through operation for internal clamping disk and stomach
After fistula ontology is set to animal rumens, then clamping, this external clamping disk and stomach fistula sheet is fixed in the outer clamping disk of fixing body
Body to be detachably connected with mode upper comparatively laborious in structure and operation, be not easy to assemble and disassemble, take time and effort.In addition, animal on the market
The gastric fistula tube body of rumen fistula is usually cylindric tube body, and when operation, internal clamping disk is towards the tube wall side of cylindric tube body
To extruding curvature it is very limited, cause the notch opened up in cud larger so that installation animal rumens fistula leakproofness
Can be poor, or even there are the risks that animal rumens fistula falls off.
Utility model content
Purpose of the utility model is to overcome the above-mentioned shortcomings and provide a kind of ruminant tumor gastric fistula, integral type is set
The elastomeric flexible rumen fistula structure set makes animal rumens fistula be convenient to mount and dismount, is time saving and energy saving.Compared with prior art, middle part court
The hollow gastric fistula tube body of two side direction caliber flarings setting and the angle of internal butterfly unit increase, so that in operation fixing body
Extruding curvature when butterfly unit is bigger.Therefore, the smaller i.e. mountable animal rumens of opening need to be only opened up on the outside of cud wall
Fistula, and smaller opening is so that animal rumens fistula sealing performance is more preferable.
A kind of ruminant tumor gastric fistula, comprising: elastomeric flexible rumen fistula structure, the hollow sleeve of integral type setting are set to
Fistula set in rumen fistula structure and the hard spiral plug for closing the fistula set；The rumen fistula structure includes
The hollow gastric fistula tube body that middle part is arranged towards two side direction caliber flarings, in the top opening of the gastric fistula tube body and court
The external butterfly unit of the radial direction inner arc setting at the middle part of the gastric fistula tube body, set on the bottom of the gastric fistula tube body
In opening and towards the radial direction inner arc at the middle part of the gastric fistula tube body be arranged internal butterfly unit, the external butterfly list
The intrados of the first and described internal butterfly unit is oppositely arranged, and the inner arc opening diameter of the external butterfly unit is less than described
The inner arc opening diameter setting of internal butterfly unit；The fistula set detachable is placed in the lumen of the gastric fistula tube body,
The hard spiral plug is screwed together with the fistula set, and the stomach fistula ontology is opened and closed by the assembly and disassembly of vice.
Preferably, the external butterfly unit and the internal butterfly unit include circular chassis and are set to described
On the periphery on circular chassis and flaring setting the dish wing, it is described annular shape chassis and the gastric fistula tube body opening integral type
Connection.
Preferably, fistula set is that PE covers, and the vice includes plug body and is set to the plug body top
Hold the plug top outer of two sides, the running-on of the plug top outer and fistula set, which contradicts, to be arranged, described in the plug body is corresponding
The inner diameter size setting of PE set.
Ruminant tumor gastric fistula provided by the utility model, due to hollow gastric fistula tube body, external butterfly unit and body
Interior butterfly unit is an integral structure, and compared with the separate structure assembling mode of the prior art, eliminates separate structure assembling work
Sequence, so that animal rumens fistula is convenient to mount and dismount, is time saving and energy saving.Cylindrical hollow gastric fistula tube body compared to the prior art, will
The structure of hollow gastric fistula tube body is set as middle part towards the fistula ontology of two side direction caliber flarings setting, it can be achieved that hollow stomach fistula
Angle between the flaring outer wall and internal butterfly unit and external butterfly unit of ontology increases, at the time of surgery, internal butterfly unit
Extruding bending freedom degree between the flaring outer wall of hollow gastric fistula tube body is bigger.Therefore, it need to only be opened up more on the outside of cud wall
Small opening, that is, mountable animal rumens fistula, and smaller opening is so that animal rumens fistula good seal performance.
