Abstract
The utility model discloses a cardiovascular expansion device. The cardiovascular expansion device comprises a hollow tube, a tapered tube and a switch. The tapered tube and the switch are respectively arranged at two ends of the hollow tube. An elastic net-shaped support and an elastic piece movably connected with the elastic net-shaped support are disposed in the hollow tube, wherein the elastic piece is of a double-spring structure arranged in sleeved mode. The cardiovascular expansion device has a simple structure but effectively achieves simple and safe installation of a support frame in a heart and blood vessels of a patient. At the same time, the cardiovascular expansion device is convenient to use and relatively applied to a current cardiovascular expansion operation.
Description
Technical field
This utility model relates to a kind of medical apparatus, especially a kind of cardiovascular extension fixture.
Background technology
At present, when carrying out the cardiovascular expansion to the patient clinically, majority mounting bracket or sacculus in patient's cardiovascular, but because the cardiovascular pipeline is thinner, pack into by hand support or sacculus are just relatively more difficult, and waste time and energy, and have increased work difficulty to the medical worker.
Therefore, need a kind of new cardiovascular extension fixture with the simple and safe problem of packing support into for patient's cardiovascular of better solution.
Summary of the invention
In view of this, this utility model is devoted to better to solve the simple and safe problem of packing support into for patient's cardiovascular, has proposed a kind of cardiovascular extension fixture.
The technical scheme that this utility model adopts is:
A kind of cardiovascular extension fixture comprises hollow pipe, is separately positioned on the conical pipe and the switch at hollow pipe two ends, wherein, and the elastic component that is provided with the elastic web support in the said hollow pipe and flexibly connects with the elastic web support; Wherein, said elastic component is the dual spring structure that is nested with.
The other end of above-mentioned elastic component is fixedly connected on the end that hollow pipe is provided with switch.
The diameter of the smallest end of above-mentioned conical pipe is greater than the diameter of elastic web support.
The diameter of above-mentioned elastic web support is greater than the diameter of elastic component.
The end diameter of above-mentioned conical pipe is 1: 2～1: 3 with the ratio of outside diameter.
The beneficial effect of this utility model is:
This utility model is simple in structure but efficiently solve simple and safe problem of packing support into for patient's cardiovascular, and is easy to use simultaneously, relatively is suitable for existing cardiovascular expansion operation.
Description of drawings
Below with reference to accompanying drawings the specific embodiments of this utility model is explained in more detail, wherein:
Fig. 1 is the structure drawing of device of this utility model;
Wherein, 1-hollow pipe, 2-conical pipe, 3-switch, 4-elastic web support, 5-elastic component.
The specific embodiment
In order to solve the simple and safe problem of packing support into for patient's cardiovascular, this utility model provides a kind of cardiovascular extension fixture.Next specify this cardiovascular extension fixture.
Fig. 1 illustrates the structure drawing of device of this utility model.This cardiovascular extension fixture comprises hollow pipe 1, is separately positioned on the conical pipe 2 and the switch 3 at hollow pipe 1 two ends, wherein, and the elastic component 5 that is provided with elastic web support 4 in the said hollow pipe 1 and flexibly connects with elastic web support 4; Wherein, the dual spring structure of said elastic component 5 for being nested with.
The other end of above-mentioned elastic component 5 is fixedly connected on the end that hollow pipe 1 is provided with switch 3.
In use, the smallest end of conical pipe 2 is inserted cardiovascular, open switch 3, elastic component 5 ejects the smallest end of elastic web support 4 from conical pipe 2, elastic web support 4 is placed in patient's cardiovascular get final product.
The diameter of the smallest end of above-mentioned conical pipe 2 is greater than the diameter of elastic web support 4, and in the time of can guaranteeing to carry out the cardiovascular dilatation, elastic web support 4 can be smoothly ejects from the smallest end of conical pipe 2.
The diameter of above-mentioned elastic web support 4 is greater than the diameter of elastic component 5.
The end diameter of above-mentioned conical pipe 2 is 1: 2～1: 3 with the ratio of outside diameter.
More than the specific descriptions of this utility model are intended to explain the implementation of specific embodiments can not be interpreted as it is restriction this utility model.Those of ordinary skills can make various variants on the basis of the embodiment that details under the instruction of this utility model, these variants all should be included within the design of this utility model.This utility model scope required for protection is only limited by described claims.
