Abstract
The utility model discloses a folding preventing serous cavity puncture indwelling needle device, comprising a puncture needle and an indwelling needle which are sleeved together. The indwelling needle comprises a connector connected with a transfusion connector and a needle handle disposed at the front end of the connector; the needle handle comprises an inner sleeve and an outer sleeve which are made of medical plastic and are connected together through the front ends; the rear ends of the inner sleeve and the outer sleeve are connected with the connector into a whole; a steel wire spring is disposed between the inner sleeve and the outer sleeve; and the steel wire spring comprises a plurality of spring rods which are disposed in a spaced manner and spring support arms which are installed on the spring rods fixedly and extend to the inner sleeve and the outer sleeve. With the steel wire spring disposed between the inner sleeve and the outer sleeve, the folding preventing serous cavity puncture indwelling needle device prevents complete bonding of the surface of an inner cavity of the indwelling needle device, solves the problem of blocking in the needle handle, guarantees a clear passage in the needle handle, and is beneficial to following drainage.
Description
Technical field
This utility model relates to a kind of anti-folding serous cavity puncture remaining needle.
Background technology
When carrying out serous cavity tapping operation, use the puncture remaining needle to puncture earlier at present, puncture after accomplishing is extracted puncture needle, and remaining needle is stayed the site of puncture.Because the remaining needle union joint is slick and sly, be difficult for fixingly, thereby remaining needle is prone to give a discount entering the skin place, the surface of internal cavity of the remaining needle needle handle after folding can be fitted, thereby causes the needle handle retention of feces and urine smooth, and the phenomenon of inadequate drainage or drain failure takes place.
The utility model content
The technical problem that this utility model will solve provides a kind of remaining needle bending back that prevents and the not anti-folding serous cavity puncture remaining needle of smooth phenomenon of front and back occurs.
For solving the problems of the technologies described above; The anti-folding serous cavity puncture remaining needle that is provided comprises puncture needle and the remaining needle that is sleeved on together; Remaining needle comprises union joint that can be connected with infusion connector and the needle handle that is installed in the union joint front end; Its construction features is: needle handle comprises that the rear end of interior cover and overcoat all is connected as a single entity with union joint by interior cover and the overcoat that medical plastic is processed and front end is connected as a single entity, and between interior cover and the overcoat wire spring is housed.
Said wire spring comprise a plurality of spring levers that are provided with at interval and be packed on the spring lever and stretch to respectively in the spring support arm of cover and overcoat.
After adopting said structure; After remaining needle is stayed the site of puncture, even remaining needle receives external force crooked, owing to be provided with wire spring between the interior cover overcoat; Thereby the remaining needle surface of internal cavity can not occur and fit fully; Avoid occurring the smooth phenomenon of retention of feces and urine in the needle handle, kept the needle handle inner chamber unobstructed, helped continuing drain.
Description of drawings
Below in conjunction with accompanying drawing this utility model is further described:
Fig. 1 is the structural representation of this utility model;
Fig. 2 is the enlarged drawing in A district among Fig. 1.
The specific embodiment
Anti-folding serous cavity puncture remaining needle as depicted in figs. 1 and 2; It is sleeved on together puncture needle 4 and remaining needle; The structure of puncture needle 4 and with the syndeton of remaining needle be prior art; Remaining needle comprises union joint 1 that can be connected with infusion connector and the needle handle 2 that is installed in union joint 1 front end; Needle handle 2 comprises the interior cover 21 and overcoat 22 by medical plastic is processed and front end is connected as a single entity; In cover 21 all be connected as a single entity with the rear end of overcoat 22 with union joint 1 front end face, between interior cover 21 and the overcoat 22 wire spring 3 is housed, wire spring 3 comprise a plurality of spring levers 31 that are provided with at interval and be packed on the spring lever 31 and stretch to respectively in the spring support arm 32 of cover 21 and overcoat 22.
