Abstract
The utility model relates to a kind of anti-discounting devices of central venous catheter, including the first spring being separately positioned on outside central vein casing main channel and subaisle and second spring, first spring and the internal diameter of second spring are adapted with the outer diameter of main channel and subaisle respectively, it further include the intersection limiting device being arranged between the first spring and second spring for preventing main channel and subaisle from intersecting, the present apparatus effectively can prevent central venous catheter from giving a discount in use.
Description
Technical field
The utility model belongs to field of medical auxiliary equipment, is related to a kind of anti-discounting device of central venous catheter.
Background technique
Existing some central venous catheter have main channel and subaisle, in use, often because of patient
Movement or the movement of conduit cause main channel or subaisle to give a discount, to influence the effect of its conveying.
Utility model content
In view of this, the purpose of this utility model is to provide a kind of anti-discounting device of central venous catheter, it can be effective
Prevent its discounting.
In order to achieve the above objectives, the utility model provides the following technical solutions:
The anti-discounting device of central venous catheter, including be separately positioned on outside central vein casing main channel and subaisle
The internal diameter of one spring and second spring, first spring and second spring is mutually fitted with the outer diameter of main channel and subaisle respectively
It answers, further includes the intersection limit dress being arranged between the first spring and second spring for preventing main channel and subaisle from intersecting
It sets.
Further, the intersection limiting device includes the tension spring being arranged between the first spring and second spring, institute
The both ends for stating tension spring are separately connected the first spring and second spring.
It further, further include the casing being arranged on the outside of elastic spring.
The utility model has the beneficial effects that:
By the way that tension spring is arranged between the first spring and second spring, it is possible to reduce the intersection between two channels is beaten
Folding, and the first spring and second spring can be used as a rigid support, by the appearance of softer main channel and subaisle
Face supports, and prevents the discounting of its own, setting casing is also for the effect for reinforcing its anti-discounting.
Detailed description of the invention
In order to keep the purpose of this utility model, technical scheme and beneficial effects clearer, the utility model provides as follows
Attached drawing is illustrated:
Fig. 1 is the structural schematic diagram of the utility model.
Specific embodiment
Below in conjunction with attached drawing, the preferred embodiment of the utility model is described in detail.
The anti-discounting device of central venous catheter as shown in Figure 1, including it is separately positioned on central vein casing main channel 1 and pair
The internal diameter of the first spring 3 and second spring 4 outside channel 2, the first spring 3 and second spring 4 respectively with main channel 1 and subaisle
2 outer diameter is adapted, and further includes being arranged between the first spring 3 and second spring 4 for preventing main channel 1 and subaisle 2 from handing over
The intersection limiting device of fork.Intersecting limiting device includes the tension spring 5 being arranged between the first spring 3 and second spring 4,
The both ends of power spring 5 are separately connected the first spring 3 and second spring 4.It further include the casing 6 that 5 outside of elastic spring is set.This
In embodiment, the length of the first spring 3 and second spring 4 can be selected according to the length of main channel 1 and subaisle 2.
Finally, it is stated that preferred embodiment above is merely intended for describing the technical solutions of the present application, but not for limiting the present application, to the greatest extent
Pipe has been described in detail the utility model by above preferred embodiment, but those skilled in the art should manage
Solution, can make various changes, without departing from the utility model claims book institute to it in the form and details
The range of restriction.
