Description
Technical field
The present invention relates to rotation pezzer's catheter,mushroom cathete testing equipment field more particularly to small blind area guide sleeves.
Background technique
Currently, the end blind area of tradition rotation pezzer's catheter,mushroom cathete detection device reaches 50mm or more, this allows for the conduit of detection
The length of finished product both ends 50mm is intended to cut off, and thus reduces the yield rate of product, improves cost, and if reducing blind area
The length of guide sleeve can be increased, so that guide sleeve nearby generates vortex, interference is generated to ultrasound examination.In addition existing guide sleeve is adopted
With nylon material, its advantage is that the material is soft, be not easy to scratch catheter surface, but process guide sleeve when, since its material is led
Machining deformation is caused, not can guarantee machining accuracy, and nylon material, when temperature change is big, thermal expansion and contraction is obvious, specifically
The guide sleeve processed in winter is shown as, can not be just installed on swivel head to summer, the guide sleeve that summer processes, to winter
The phenomenon for assembling pine is occurred as soon as, thus reduces detection accuracy.
Summary of the invention
The applicant is directed to above-mentioned existing issue, has carried out Improvement, provides a kind of small blind area guide sleeve, not only shorten
End blind area, while avoiding generating vortex, ultrasound examination will not be interfered.
The technical solution adopted in the present invention is as follows:
Small blind area guide sleeve, the guide sleeve main body including offering conduit through hole, along the periphery cooperation bone of the guide sleeve main body
Frame set circumferentially opens up the second extrados in one end periphery of the guide sleeve main body, opens at the both ends of the conduit through hole
If the concentric pilot hole with conduit through hole；It further include opening up multiple gas vents along axial direction in the guide sleeve body interior, it is each to arrange
One end aperture of stomata is opened in the inner wall of a pilot hole, and the other end aperture of each gas vent is opened in the tail portion of guide sleeve main body
Outer wall.
Its further technical solution is:
Each gas vent is symmetrical centered on the conduit through hole；
The angle γ, the angular range at the angle γ are formed between the central axes of the gas vent and the central axes of conduit through hole
It is 5~30 °；
The inner hole wall of the pilot hole circumferentially forms intrados, between the intrados and the central axes of conduit through hole
Shape is at angle β, and the angular range at the angle β is 5~30 °；
It is respectively provided with the first extrados at skeleton set both ends, is formed between the cambered surface and horizontal plane of first extrados
The angle α, the angular range at the angle α are 5~30 °；
The skeleton set is stainless steel structure.
Beneficial effects of the present invention are as follows:
The configuration of the present invention is simple, it is easy to use, by cooperating stainless steel insert set in guide sleeve main body periphery, it can guarantee and lead
The machining accuracy for covering main body outer circle, will not scratch the surface of guide sleeve main body, guide sleeve main body can be reused with secondary operation, be kept away
Exempt from the problem of previous directly processing guide sleeve is easily deformed, machining accuracy has been effectively ensured.The arrangement of skeleton set is also avoided that simultaneously
Thermal expansion and contraction of the guide sleeve main body of nylon material when difference variation is big, by the way that outer arc is arranged in the end of guide sleeve main body
Face, while increasing gas vent, it avoids it from generating vortex in water filling process, is not easy to interfere ultrasound examination, while can also incite somebody to action
The air of internal cavity is quickly discharged, and improves water-filling speed, reduces blind area.
Detailed description of the invention
Fig. 1 is the structural diagram of the present invention.
Wherein: 1, skeleton set；101, the first extrados；2, guide sleeve main body；201, gas vent；202, conduit through hole；
203, pilot hole；204, the second extrados；205, intrados.
Specific embodiment
Illustrate a specific embodiment of the invention below.
As shown in Figure 1, small blind area guide sleeve includes the guide sleeve main body 2 for offering conduit through hole 202, along guide sleeve main body 2
Periphery cooperation skeleton set 1, skeleton set 1 with a thickness of 4~8mm, skeleton set 1 is stainless steel structure.Outside one end of guide sleeve main body 2
Week circumferentially opens up the second extrados 204, opens up and conduit through hole 202 is concentric leads at the both ends of conduit through hole 202
To hole 203, the inner hole wall of pilot hole 203 circumferentially forms intrados 205, the central axes of intrados 205 and conduit through hole 202
Between shape it is at angle β, the angular range at the angle β is 5~30 °.As shown in Figure 1, further include axially inside opened up in guide sleeve main body 2 it is more
Gas vent 201, one end aperture of each gas vent 201 are opened in the inner wall of a pilot hole 203, the other end of each gas vent 201
Aperture is opened in the tail portion outer wall of guide sleeve main body 2.As shown in Figure 1, above-mentioned gas vent 201 is centered on conduit through hole 202
It is symmetrical.The angle γ, the angular range at the angle γ are formed between the central axes of gas vent 201 and the central axes of conduit through hole 202
It is 5~30 °.1 both ends are covered in skeleton and are respectively provided with the first extrados 101, are formed between the cambered surface and horizontal plane of the first extrados 101
The angle α, the angular range at the angle α are 5~30 °.
Pass through the second extrados 204 of setting, during ultrasound examination, above-mentioned first extrados in actual use process
101, the second extrados 204 plays guiding, guiding function to water flow, avoids generating vortex during ultrasound examination.Other
Positioning is easier when the setting of one extrados 101 can also assemble convenient for the present invention to swivel head.The setting of gas vent 201 is so that lead
It manages after entering, by the intrados 205 of pilot hole 203, so that bubble is arranged along the entrance of intrados 205 in penetrating catheter procedure
In stomata 201, after swivel head starts rotation, the air inside guide sleeve main body 2 is quickly discharged by gas vent 201, is improved
The water-filling speed of cavity, conduit, which enters inside swivel head, can carry out carrying out flaw detection after 15mm, therefore blind area is made to be reduced to 15mm.
Above description is explanation of the invention, is not intended to limit the invention, and limited range of the present invention is referring to right
It is required that the present invention can make any type of modification without prejudice to basic structure of the invention.
