Description

TECHNICAL FIELD

[0001] The utility model relates to a puncture ware technical field, concretely relates to a valve switch. BACKGROUND

[0002] Puncture ware is the medical field widely used medical instrument, through the puncture ware establishment operation channel, various specifications medical instrument is through the puncture ware, enters the human body, acts on the patient, and at present, almost all valve switches on the market are too close to the luer joint, when normally using, the wrench position of valve switch is too close to the luer joint and pipeline after the luer joint connects the pipeline, and the operation is inconvenient, and unnecessary position is easily touched, and the operation burden is increased. CONTENT OF THE UTILITY MODEL

[0003] In order to solve the above problems, the utility model provides a valve switch, and unnecessary touching and misoperation due to the luer joint connected with the pipeline are not easy to occur.

[0004] The technical scheme of the utility model is as follows: a valve switch, including valve seat, valve and valve wrench, the luer joint is arranged on the valve seat, and the luer joint is vertically arranged with the valve seat, the valve is rotationally connected with the valve seat, the tail end of the valve is arranged on the outside of the valve seat and is connected with the valve wrench, and the valve wrench is inclined outward.

[0005] Further, the included angle between the center line of the valve wrench and the center line of the valve is 40-50 DEG.

[0006] Further, the valve seat is a tubular structure, a cylindrical valve is arranged in the valve seat, the valve is limited in the valve seat and is rotationally connected with the valve seat, the side wall of the valve is provided with a through hole one communicated with the luer joint and a through hole two communicated with the inner cavity of the puncture ware, the through hole one and the through hole two are on a straight line, a channel is arranged in the valve, the channel is communicated with the through hole one and the through hole two or is staggered by rotating the valve, and the tail end of the valve is connected with the valve wrench outside the valve seat.

[0007] Further, the valve wrench includes a wrench handle and a wrench arm body, the wrench handle is a semicircular structure, the two sides of the wrench handle are concave structures, and the position of the wrench handle is higher than the position of the luer joint.

[0008] The utility model has the advantages that:

[0009] The valve wrench is rotated, the opening and closing of the valve can be controlled, the valve wrench is inclined outward, the distance is much larger than that of other puncture wares, unnecessary touching and misoperation due to the luer joint connected with the pipeline do not occur in clinical application. BRIEF DESCRIPTION OF DRAWINGS

[0010] The utility model will be further described below in combination with the drawings and embodiments.

[0011] Figure 1 It is a schematic view of the luer valve of the puncture device. DETAILED DESCRIPTION

[0012] The technical scheme of the utility model will be described clearly and completely below through specific embodiments.

[0013] Reference Figure 1 , a valve switch of the utility model, including valve seat 2, valve 6 and valve wrench 3, luer joint 1 is arranged on valve seat 2, and the luer joint is arranged perpendicularly with valve seat 2, valve 6 is rotatably connected with valve seat 2, and the tail end of valve 6 is arranged on the outside of valve seat 2 and is connected with valve wrench 3.

[0014] Valve seat 2 is tubular structure, and columnar valve 6 is arranged in the inside, valve 6 is limited in valve seat 2 and is rotatably connected with valve seat 2, the side wall of valve 6 is provided with through hole one communicated with luer joint 1 and through hole two communicated with the inner cavity of puncture device, and through hole one and through hole two are on a straight line, and channel is arranged in valve 6, and the channel is communicated with through hole one and through hole two or staggered by rotating valve 6, the utility model is rotated according to the arrow direction of 4, and valve wrench 3 can control the opening and closing of valve.

[0015] The tail end of valve 6 is connected with valve wrench 3 outside valve seat 2, and valve wrench 3 includes wrench handle and wrench arm body, the wrench handle is semicircular structure, the two sides of the wrench handle are concave structure, and the position of the wrench handle is higher than the position of luer joint.

[0016] The center line of valve wrench 3 and the center line of valve form an angle of 40-50 °, and valve wrench 3 is inclined outward, so that the distance of 5 is much larger than other puncture devices, and unnecessary touch and misoperation can not occur when being applied clinically because luer joint is connected with pipeline.

[0017] The above is only the preferred embodiment of the utility model, and is not used to limit the utility model, and various modifications or equivalent replacements can be made to the utility model within the utility model's essence and protection range by those skilled in the art, and the modification or equivalent replacement should also be regarded as falling within the protection range of the utility model's technical scheme.
