Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of can save material, push rod can be made to keep the irrigator of good mechanical strength again.
Further technical problem to be solved in the utility model is to provide a kind of irrigator, and it can effectively prevent operator from this irrigator is accessed the infusion products of such as venous detaining needle, needleless joint and so on by mistake.
The technical scheme that this utility model adopts is: a kind of irrigator, comprises outer cylinder body, is plugged in the push rod in this outer cylinder body and is fixed on the plug of push rod front end; The front end of outer cylinder body is provided with a junction block portion, and the main body of push rod is made up of at least three rib sheets; Be characterized in, at least the surface of a slice rib sheet is provided with groove.
Above-mentioned irrigator, wherein, the main body of push rod is made up of four rib sheets, and these four rib sheets are that cross intersects.
Above-mentioned irrigator, wherein, the surface of four rib sheets is equipped with groove; Wherein two panels is positioned at conplane rib sheet and is respectively equipped with the strip groove in axial direction extended symmetrically, in addition two panels be positioned at conplane rib sheet symmetrically respectively interval many transversely grooves that extend of direction are set.
Above-mentioned irrigator, wherein, the main body of push rod is made up of three rib sheets, and a side of these three rib sheets interconnects, and the angle between adjacent every two pieces of rib sheets is 120 °.
Above-mentioned irrigator, wherein, the lateral surface in junction block portion is provided with outwardly external screw thread.
This utility model at least has the following advantages:
1., although in the prior art, the object of saving material can be reached by the rib sheet of the push rod at irrigator being arranged through hole, also significantly can reduce the mechanical strength of rib sheet simultaneously, easily causing push rod phenomenon of rupture.This utility model, by arranging groove on the surface of rib sheet, balances the relation of saving material and making push rod keep between sufficient intensity, had both reduced the production cost of irrigator, and also enable the mechanical strength that push rod keeps good;
2. irrigator of the present utility model is provided with outwardly external screw thread on the lateral surface in outer cylinder body junction block portion, can effectively prevent operator from this irrigator is accessed the infusion products of such as venous detaining needle, needleless joint and so on by mistake.

Detailed description of the invention
Below in conjunction with accompanying drawing, this utility model is described in further detail.
Please refer to Fig. 1 to Fig. 8.Outer cylinder body 1, push rod 2 and plug 3 is comprised according to the irrigator of this utility model one embodiment.Plug 3 is fixed on the front end of push rod 2, and can vertically move in outer cylinder body 1 together with push rod 2.
The front end of outer cylinder body 1 is provided with junction block portion 11, and the lateral surface in junction block portion 11 is provided with outwardly external screw thread 12.Due to the infusion connector of the infusion products of existing such as venous detaining needle, needleless joint and so on being also provided with external screw thread usually, therefore, can not be connected for mating with above-mentioned infusion products by this irrigator of alert on the one hand after junction block portion 11 is provided with external screw thread, also cannot realize on the other hand connecting, thus can effectively prevent operator from being accessed in above-mentioned infusion products by this irrigator by mistake.
In figure, the main body of push rod 2 is made up of four rib sheets 21,22,23 and 24, and these four rib sheets are that cross intersects.Wherein, rib sheet 21 and rib sheet 22 are positioned at same plane, and rib sheet 23 and rib sheet 24 are positioned at same plane.The object save material for reaching, reducing production cost, at least the surface of a slice rib sheet is provided with groove wherein, this groove only can be opened in the upper surface of rib sheet, also only can be opened in the lower surface of rib sheet, or all offers groove on the upper and lower surface of rib sheet.In the embodiments illustrated in the figures, the surface of four rib sheets is equipped with groove.Wherein, the upper and lower surface of the rib sheet of every a slice is equipped with groove.Rib sheet 21,22 is respectively equipped with symmetrically the strip groove 211,221 in axial direction extended, on rib sheet 23,24 symmetrically respectively interval arrange many transversely direction extend groove 231,241.The arrangement of this groove can balance the relation of saving material and making push rod keep between sufficient intensity preferably, has both reduced the production cost of irrigator, and has also made push rod have good mechanical strength.
Fig. 1 to Fig. 8 is only a specific embodiment of the present utility model, but it should be understood by one skilled in the art that this utility model is not limited to embodiment described here, such as, the main body of push rod 2 also can be made up of three rib sheets, a side of these three rib sheets interconnects, angle between adjacent every two pieces of rib sheets is 120 °, and at least the surface of a slice rib sheet is provided with groove wherein.
