Abstract
This utility model relates to a kind of drainage tube extension tube, one end of extension tube is for connecting drainage bag, the other end of extension tube is connected with the end of drainage tube, the inwall both sides of the junction of extension tube and drainage tube are provided with several kicks, projection is tilted to down, extension tube is built-in with check valve, and extension tube is provided with negative pressure device, is provided with flow regulator below negative pressure device.This utility model structure is simple, design ingenious, easy to use, the inclination kick that seam is arranged can make drainage tube be connected tight difficult drop-off with extension tube, uses extension tube, increases the length of drainage tube, use more convenient, extension tube arranged outside sleeve pipe, prevents extension tube from affecting the discharge of hydrops because of distortion, and can repeatedly use.
Description
Technical field
This utility model relates to a kind of extension tube of drainage tube, belongs to technical field of medical instruments.
Background technology
Traditional thoracic cavity seroperitoneum, pneumatosis are based on tap repeatedly, by inserting central venous catheter in disposable body cavity, sustainable drain hydrops, pneumatosis, to occur in body that pressure such as to reduce rapidly at the complication in order to avoid reducing rapidly because of body fluid, therefore conventional drainage tube caliber is less, and drainage tube limited length needs of patients in vitro uses inconvenience when moving or walk, drainage tube is generally single use does not have arrangements for speed regulation and the phenomenon that drainage-fluid refluxes may appear in patient in moving process.
Summary of the invention
The purpose of this utility model is that as drainage tube, caliber is little in use in order to solve existing central venous catheter, length is shorter and can not control hydrops flow velocity and easily occur the shortcoming that drainage-fluid refluxes, provide a kind of structure simple, the drainage tube extension tube that can repeatedly use compact to design.
This utility model adopts following technical scheme: a kind of drainage tube extension tube, one end of described extension tube is for connecting drainage bag, the other end of described extension tube is connected with the end of drainage tube, the inwall both sides of the junction of described extension tube and drainage tube are provided with several kicks, described projection is tilted to down, described extension tube is built-in with check valve, described extension tube is provided with negative pressure device, extension tube above described drainage bag is provided with flow regulator, and described extension tube skin is provided with a sleeve pipe.
Further, described negative pressure device comprises air bag, exhaustor and one-way exhaust valve, and one end of described air bag is connected in extension tube by exhaustor, and the other end of described air bag connects one-way exhaust valve.
Further, described extension tube adopts rubber tube to make, and the diameter of described extension tube is greater than drainage tube.
Further, described flow regulator comprises housing and roller, and described housing is socketed in extension tube, is provided with roller groove in described housing, and described roller groove is skewed, and described roller moves along roller groove can reach the cross section size of adjustment extension tube.
Further, the end both sides of described sleeve pipe are respectively arranged with retainer ring.
Further, the junction of described extension tube and drainage tube is provided with sealing ring.
This utility model structure is simple, design ingenious, easy to use, the inclination kick that seam is arranged can make drainage tube be connected tight difficult drop-off with extension tube, uses extension tube, increases the length of drainage tube, use more convenient, extension tube arranged outside sleeve pipe, prevents extension tube from affecting the discharge of hydrops because of distortion, and can repeatedly use.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Reference numeral: extension tube 1, sleeve pipe 2, drainage tube 3, drainage bag 4, check valve 5, kick 6, air bag 7, exhaustor 8, one-way exhaust valve 9, flow regulator 10, sealing ring 11, retainer ring 12.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model will be further described.
As shown in Figure 1, a kind of drainage tube extension tube, extension tube 1 skin is provided with a sleeve pipe 2, sleeve pipe 2 adopts hard plastics to make can to ensure extension tube 1 to be not easily distorted bending and affect the discharge of hydrops, one end of extension tube 1 is for connecting drainage bag 4, the other end of extension tube 1 is connected with the end of drainage tube 3, extension tube 1 and the inwall both sides of the junction of drainage tube 3 are provided with that several are little prominent 6, kick 6 is tilted to down, fully can ensure that extension tube is connected with the seam of drainage tube closely not easily to unclamp, the junction of extension tube 1 and drainage tube 3 is provided with sealing ring 11, ensure that extension tube 1 is connected with drainage tube 3 closely, extension tube 1 is built-in with check valve 5, the phenomenon that can fully prevent drainage-fluid from flowing backwards, extension tube 1 is provided with negative pressure device, negative pressure device comprises air bag 7, exhaustor 8 and one-way exhaust valve 9, one end of air bag 7 is connected in extension tube 1 by exhaustor 8, the other end of air bag 7 connects one-way exhaust valve 9, the top of the below drainage bag of negative pressure device is provided with flow regulator 10, flow regulator 10 comprises housing and roller, housing is socketed in extension tube, roller groove is provided with in housing, roller groove is skewed, roller moves along roller groove can reach the cross section size of adjustment extension tube, the output of hydrops and pneumatosis can be controlled according to patient's actual needs and health, the end both sides of sleeve pipe 2 are respectively arranged with retainer ring 12, extension tube can be fixed on a side.
Only extension tube 1 need be connected to the end of drainage tube 3 during use with one end of kick 6, according to service condition cutting extension tube to suitable length, extension tube 1 other end is connected with drainage bag, flow regulator 10 is adjusted to minimum, then the tight air bag 7 of hand unclamps, make to form negative pressure in extension tube 1 and drainage tube 3, because drainage tube 3 communicates with chest, therefore also subnormal ambient can be formed in body, under the effect of negative pressure, make chest drainage more thorough, also can solve simultaneously and circulate not smooth problem because blocking the drainage tube 3 that causes and extension tube 1, can repeatedly use after drainage tube extension tube cleaning in this utility model.
