Abstract
A disposable intravenous infusion needle is formed by sequentially connecting a syringe needle, a needle base and a flexible pipe. A needle handle is arranged on the needle base, a tubular protection sleeve sleeves the syringe needle, and the plastic sleeve is a plastic pipe with two ends open. A long fracture is formed in the side of the protection sleeve in the axial direction, a lateral wing is arranged on the side of the protection sleeve, and the lateral wing is parallel to the long crack. The infusion needle adopts the design that the protection sleeve does not deviate from the flexible pipe, the protection sleeve is limited by the needle handle, a user can vertically slide the protection sleeve on the flexible pipe and the syringe needle by holding the lateral wing of the protection sleeve, abandoning of the protection sleeve is reduced, the protection sleeve can sleeve the syringe needle again conveniently after use to prevent the syringe needle from being exposed.
Description
Technical field
This utility model belongs to technical field of medical instruments, is specifically related to a kind of transfusion needle product of being convenient to safe retrieving.
Background technology
At present, the disposable use venoclysis needle product that hospital is generally used, its structure is needle stand, flexible pipe, needle tubing and sheath composition, there is following problem: sheath is determined abandoned after sealing off use, and after having infused, dropped into often in medical waste sharp disposable container for the processing of syringe needle.After use, pull out syringe needle in dropping into during sharp disposable container, these are not protected and very likely puncture operator or personnel's skin around in exposed contaminated pinhead, and the incidence rate of pricking wound is very high, thereby causes the propagation of pathogenic bacteria; In the process of these Biohazard Wastes of recovery, sharp syringe needle can sting breaking garbage-bag simultaneously, causes the toughness of refuse bag to decline, and has damaged risk, may cause being scattered of Biohazard Waste.In use, abandoning of sheath becomes a kind of custom; Even if do not abandon sheath, sheath volume is little, according to hospital operation regulation, for fear of the generation of pricking wound, does not allow both hands cap relatively again, just causes these problems to be difficult to solve just because of the disengaging completely of sheath and needle tubing or syringe needle.
Utility model content
Technical problem to be solved in the utility model is for the deficiency in background technology, and a kind of disposable use venoclysis needle of being convenient to safe retrieving is provided.
In order to address the above problem by the following technical solutions: disposable venous infusion needle, be mainly in series successively by syringe needle, needle stand, flexible pipe, needle stand is provided with needle handle, and pinhead sleeve is provided with tubular sheath, the plastic tube that sheath is both ends open; Long crack is in axial direction established in the side of sheath, is provided with flank in sheath side, and flank is parallel to long crack.
Long crack is along being circumferentially arranged on a side of sheath, the opposite side that flank is arranged on sheath vertically, and flank and long crack are oppositely arranged.
Wherein, growing crack runs through and is arranged on sheath side.
And the long position in crack and the position of needle handle are corresponding.
The internal diameter of described sheath matches with the external diameter of flexible pipe, and sheath lower end is set on needle stand, and long slotted opening is in needle handle place, and needle handle is through long crack.
This utility model has adopted the sheath design that does not depart from flexible pipe, sheath is taking needle handle as spacing, and hand-held sheath flank can slide up and down on pin flexible pipe and syringe needle, has reduced abandoning of sheath, after using, very easily sheath is set in outside syringe needle again, prevents that syringe needle from exposing.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the top view of sheath.
Detailed description of the invention
As shown in Figure 1, disposable use venoclysis needle, is mainly in series successively by syringe needle 1, needle stand 2, flexible pipe 3.Needle stand 2 is provided with needle handle 4, is arranged with sheath 5 on syringe needle 1, the plastic tube that sheath 5 is both ends open, and the internal diameter of sheath 5 matches with the external diameter of needle stand 2 front ends, and sheath 5 lower ends are set on needle stand 2.As shown in Figure 2, the side of sheath 5 is in axial direction also run through and is provided with long crack 5-1, because sheath belongs to flexible pipe, long closing of fracture, sheath 5 sides are provided with flank 5-2.Long crack 5-1 and flank 5-2 be not in same level and on same straight line.Needle handle is through long crack, and long crack 5-1 can hold the thickness of needle handle 4, and needle handle 4 is passed in long crack 5-1 from inside to outside.
Sheath can slide up and down along the long fissure direction of flexible pipe, when flank is convenient to slide up and down, sheath is gripped, and needle handle is for direction and the position of limit slippage.
