Abstract
The utility model discloses a kind of pre-filled catheter flusher of improvement, comprise core bar, piston and sleeve, piston is installed on core bar, and core bar completes flushing together with the solution in piston propelling sleeve, and core bar near-end forms buckle a, the outside of buckle a forms buckle a outer face, have convex edge near the core bar top at buckle a place, sleeve proximal end forms crimping, forms buckle b outside crimping, hub distal end forms pointed cone along hub distal end inner surface, is stamped pointed cone cap outside pointed cone.Catheter flusher of the present utility model arranges buckle a on core bar, buckle b is set on sleeve accordingly, when core bar is rinsed together with the solution in piston propelling sleeve, buckle a outer face just contacts with crimping, buckle a and buckle b interlocks, can prevent from piston from contacting with hub distal end inner surface crimp occurs causing resilience, and cause described catheter flusher to be correlated with blood back, reusing of catheter flusher can be avoided simultaneously.
Description
Technical field
This utility model relates to a kind of irrigator, particularly relates to a kind of pre-filled catheter flusher of improvement.
Background technology
In prior art, catheter flusher has several master units such as core bar, piston and sleeve, core bar completes flushing together with the solution in piston propelling sleeve, in progradation, neither one position-limiting action, core bar is excessively advanced, forces piston contact with hub distal end inner surface and crimp occurs, so cause catheter flusher to be correlated with blood back.Therefore, need to provide a kind of new technical scheme to solve the problems referred to above.
Utility model content
For solving the problem, this utility model provides a kind of pre-filled catheter flusher of improvement.The relevant blood back of catheter flusher can not be caused.
The technical solution adopted in the utility model is:
A kind of pre-filled catheter flusher of improvement, comprise core bar, piston and sleeve, described piston is installed on core bar, described core bar completes flushing together with the solution in piston propelling sleeve, one end of described core bar is core bar near-end, and the other end of described core bar is core distal end, and described core bar near-end forms buckle a, the outside of described buckle a forms buckle a outer face
Near the core bar top at buckle a place, there is convex edge, one end of described sleeve is sleeve proximal end, and the other end of described sleeve is hub distal end, and described sleeve proximal end forms crimping, form buckle b outside described crimping, described hub distal end forms pointed cone along hub distal end inner surface.
When described buckle a outer face contacts with crimping, excessively advance for limiting core bar, buckle a and buckle b interlocks simultaneously, rebounds for preventing core bar.
Described core bar main body is core bar elongated portion.
Pointed cone cap is stamped outside described pointed cone.
Described solution is stored in sleeve lateral wall inner surface, piston distal surface and the space that surrounds of pointed cone inner surface.
The beneficial effects of the utility model: catheter flusher of the present utility model arranges buckle a on core bar, buckle b is set on sleeve accordingly, when core bar is rinsed together with the solution in piston propelling sleeve, buckle a outer face just contacts with crimping, buckle a and buckle b interlocks, can prevent from piston from contacting with hub distal end inner surface crimp occurs causing resilience, and cause described catheter flusher to be correlated with blood back, reusing of catheter flusher can be avoided simultaneously.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.Following examples, only for illustration of this utility model, are not used for limiting protection domain of the present utility model.
As shown in figures 1 and 3, the pre-filled catheter flusher of a kind of improvement of the present utility model, comprise core bar 1, piston 3 and sleeve 2, piston 3 is installed on core bar 1, core bar 1 completes flushing together with the solution in piston 3 propelling sleeve 2, one end of core bar 1 is core bar near-end 11, the other end of core bar 1 is core distal end 12, core bar 1 near-end forms buckle a16, the outside of buckle a16 forms buckle a outer face 15, near core bar 1 top at buckle a16 place, there is convex edge 13, one end of sleeve 2 is sleeve proximal end 21, the other end of sleeve 2 is hub distal end 22, sleeve proximal end 21 forms crimping 23, buckle b28 is formed outside crimping 23, hub distal end 22 forms pointed cone 27 along hub distal end inner surface 26, pointed cone cap 5 is stamped outside pointed cone 27.
With reference to figure 2, when buckle a outer face 15 contacts with crimping 23, excessively advance for limiting core bar 1, buckle a16 and buckle b28 interlocks simultaneously, rebounds for preventing core bar 1.
Above-mentioned said core bar 1 main body is core bar elongated portion 14.Core bar 1 advances in sleeve 2 along this elongated portion.
Above-mentioned said solution 4 is stored in sleeve lateral wall inner surface 25, piston distal surface 31 and the space that surrounds of pointed cone 27 inner surface.Sleeve lateral wall inner surface 25 refers to the inner surface of sleeve lateral wall 24.
With reference to figure 2, when the catheter flusher of the technical program uses, screw out pointed cone cap 5, grip sleeve 2 and pointed cone 27 screwed in the catheter interface connected and need to rinse, crimping 23 is propped up with forefinger and middle finger, thumb press convex edge 13, inject solution 4 irrigating catheter, when being positioned at the piston distal surface 31 contact sleeve distal inner surface 26 of piston 3 of core bar 1 far-end, buckle a outer face 15 just contacts with crimping 23, buckle a16 and buckle b28 interlocks, thus restriction core bar continues to advance and bounce-back, promotion is now stopped to complete flushing, be separated catheter flusher of the present invention.The effect of the catheter flusher of the technical program just contacts with crimping 23 in buckle a outer face 15, buckle a16 and buckle b28 interlocks, can prevent from piston 3 from contacting with hub distal end inner surface 26 crimp occurs causing resilience, and cause described catheter flusher to be correlated with blood back, reusing of catheter flusher can be avoided simultaneously.
