Abstract
The utility model discloses an insertion tube of a bronchoscope. The insertion tube of the bronchoscope comprises a cannula, a stainless steel woven net tube and a spring tube, wherein the stainless steel woven net tube is arranged on the spring tube in a sleeved mode, the cannula is arranged on the stainless steel woven net tube in a sleeved mode, extending sections are arranged at the two ends of the stainless steel woven net tube respectively and are exposed on the sides of the cannula, the external diameter of one end of the cannula is larger than the external diameters of other parts of the cannula, and oblique planes are arranged between every two adjacent parts with different diameters of the cannula. The insertion tube of the bronchoscope has the advantages that operation is flexible, simple and direct, diagnosis capacity and efficiency can be improved, and pain of a patient during examination is relieved.
Description
Technical field
This utility model relates to medical appurtenance field, especially a kind of bronchoscope insertion tube.
Background technology
Bronchoscope is widely used in the diagnosis of respiratory system disease, and the insertion tube on bronchoscope is put into by nasal cavity via oral cavity or tracheotomy mouth is put into, and then diagnoses.And the design of existing bronchoscope insertion tube is not ideal enough, hardness is large, and bronchial diagnosis and treatment are brought to significant limitation, and it is also long that patient bears the painful time at diagnostic procedure.
Utility model content
The purpose of this utility model is to provide a kind of bronchoscope insertion tube.
To be solved in the utility model is that the design of existing bronchoscope insertion tube is not ideal enough, and hardness is large, and bronchial diagnosis and treatment are brought to significant limitation, and patient bears also long problem of painful time at diagnostic procedure.
The technical scheme that this utility model solves its technical problem employing is: this utility model comprises sleeve pipe, rustless steel knitmesh pipe and bourdon tube, rustless steel knitmesh pipe box is on bourdon tube, sleeve pipe is placed on rustless steel knitmesh pipe, the two ends of described rustless steel knitmesh pipe are respectively equipped with extension, are exposed to the avris of sleeve pipe; The described sleeve pipe at one end external diameter of portion is greater than the external diameter of sleeve pipe remainder, between two place's external diameter differences in height, is provided with inclined-plane.
The beneficial effects of the utility model are: sleeve pipe is greater than the external diameter of sleeve pipe remainder at the external diameter apart from its end, between two place's external diameter differences in height, be provided with inclined-plane, such design makes its pipe easily insert trachea but non-easy damaged mucosa, and the hardness of the sleeve pipe polyurethane material of external diameter enlarged portion is less than the sleeve pipe material of all the other sections.Bourdon tube employing rustless steel steel disc is made the internal diameter size that can control sleeve pipe.Rustless steel knitmesh pipe box is in bourdon tube outside, and rustless steel knitmesh inside pipe wall two ends are welded with stannum, and because rustless steel knitmesh pipe is apertured, stannum can be penetrated on bourdon tube, is then fixed together with bourdon tube.Extension has been designed at the two ends of rustless steel knitmesh pipe, adapter ring can be installed better and be connected other pipes.Sleeve pipe adopts polyurethane material, and tensile strength, tearing toughness are good, long service life.Rustless steel knitmesh pipe can be controlled the level of stretch of sleeve pipe.Cover leather sheath, in bushing outer surface, has been protected sleeve pipe.The white bed of material can increase the smoothness of cover epidermis face as overcoat.
This utility model flexible operation, simple, direct, is conducive to improve diagnosis capability and diagnosis efficiency, has reduced the pain of patient in checking process.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail.
As shown in Figure 1, this utility model comprises sleeve pipe 3, rustless steel knitmesh pipe 4 and bourdon tube 5.
Rustless steel knitmesh pipe 4 is placed on bourdon tube 5, and sleeve pipe 3 is placed on rustless steel knitmesh pipe 4, and the two ends of rustless steel knitmesh pipe 4 are respectively equipped with extension, are respectively extension 1 and extension 7, are exposed to the avris of sleeve pipe 3.
The sleeve pipe 3 at one end external diameter of portion 6 is greater than the external diameter of sleeve pipe remainder, between two place's external diameter differences in height, be provided with inclined-plane 9, such design makes its pipe easily insert trachea but non-easy damaged mucosa, and the hardness of the sleeve pipe polyurethane material of external diameter enlarged portion is less than the sleeve pipe material of all the other sections.
On the inwall at rustless steel knitmesh pipe 4 two ends (2 and 8), be welded with stannum, because rustless steel knitmesh pipe 4 is apertured, stannum can be penetrated on bourdon tube, is then fixed together with bourdon tube.
On the external diameter of extension 1 and extension 7, be welded with stannum, the benefit of scolding tin is to control the size of external diameter, and after scolding tin, external diameter is no more than 3.4mm.
Sleeve pipe 3 external diameters are provided with cover skin, and cover epidermis face scribbles the white material of layer of transparent.
The scope of insertion tube total length is 320mm-322mm.
The helical structure that bourdon tube 5 processes for rustless steel steel disc, sleeve pipe 3 adopts polyurethane tube.
