Abstract
The utility model relates to a novel venous indwelling needle which comprises a connector (1), an extending tube (2) communicated with an outlet of the connector (1), an indwelling needle seat (3) communicated with the extending tube (2), and a needle head (4) arranged at the end portion of the indwelling needle seat (3). The novel venous indwelling needle further comprises a positive pressure valve (6) and a single hand clamp (5), the positive pressure valve (6) is fixedly arranged on the inlet of the connector (1), the single hand clamp (5) is arranged on the extending tube (2), the extending tube (2) is a rubber flexible hose, the indwelling needle seat (3) is of a transparent structure, and the tail portion of the indwelling needle seat (3) is further provided with a needle holding handle (7) which is a plastic slice of any shapes. The novel venous indwelling needle has the advantages of being simple and reasonable in structural design, low in production cost, simple and convenient when medical personnel operate the needle, capable of solving the problem of venous hemorrhage and the problem that blood enters a transfusion bottle from the needle head after the needle head is punctured into a vein, and reducing pains of a patient.
Description
Technical field
This utility model relates to a kind of technical field of medical instruments, particularly a kind of novel venous detaining needle.
Background technology
Remaining needle uses increasingly extensive clinically, is usually used in critical patient's rescue, cancer of late stage, venipuncture difficulty greatly or baby's transfusion.Remaining needle is generally by the medicinal liquid inlet attack, prolong pipe, keeping somewhere needle stand and syringe needle forms, the indwelling needle stand of existing venous detaining needle adopts metal material to make usually, prolonging pipe then adopts rubber hose to make usually, it all is light-proof material, when medical personnel puncture to the patient's vein blood vessel, whether need to observe syringe needle thrusts in the vein blood vessel of sufferer exactly, mainly according to the time observe in the remaining needle whether the blood back phenomenon is arranged, but because the opacity of keeping somewhere needle stand and prolonging pipe, medical personnel can't confirm at short notice whether syringe needle has thrust vein blood vessel, this brings meaningless misery to the patient, has also reduced medical personnel's work efficiency simultaneously.
The utility model content
The purpose of this utility model is to overcome the shortcoming of prior art, provide a kind of simple in structure, easy to operate, can effectively solve syringe needle and sting fashionable venous hemorrhage and be back to novel venous detaining needle in the transfusion device.
The purpose of this utility model is achieved through the following technical solutions: a kind of novel venous detaining needle, it comprises joint, the prolongation pipe that is communicated with the outlet of joint, the indwelling needle stand that is communicated with the prolongation pipe and is installed in the syringe needle of keeping somewhere the needle stand end, it also comprises positive valve and singlehanded folder, positive valve is fixedly mounted on the porch of joint, prolong pipe and be provided with singlehanded folder, described indwelling needle stand is the transparent mode structure.
Described prolongation pipe is rubber hose.
The afterbody of described indwelling needle stand also is provided with holds needle handle, holds the plastic tab that needle handle is arbitrary shape.
The beneficial effects of the utility model are: this utility model reasonable in design and simple, and production cost is low, and medical personnel are simple and convenient when operation, and can effectively solve after syringe needle thrusts vein, venous hemorrhage, the problem that blood enters infusion bottle from syringe needle, minimizing patient's misery.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Among the figure: the 1-joint, 2-prolongs pipe, and 3-keeps somewhere needle stand, the 4-syringe needle, the singlehanded folder of 5-, the 6-positive valve, 7-holds needle handle.
The specific embodiment
Below in conjunction with accompanying drawing this utility model is further described, but protection domain of the present utility model is not limited to the following stated.
As shown in Figure 1, a kind of novel venous detaining needle, it comprises joint 1, the prolongation pipe 2 that is communicated with the outlet of joint 1, manages the 2 indwelling needle stands 3 that are communicated with and be installed in the syringe needle 4 of keeping somewhere needle stand 3 ends with prolongation, it also comprises positive valve 6 and singlehanded folder 5, positive valve 6 is fixedly mounted on the porch of joint 1, prolong pipe 2 and be provided with singlehanded folder 5, prolonging pipe 2 is rubber hose.Described indwelling needle stand 3 is the transparent mode structure, and the afterbody of keeping somewhere needle stand 3 also is provided with holds needle handle 7, holds needle handle 7 and is the plastic tab of arbitrary shape.
Work process of the present utility model is as follows: take out venous detaining needle in packaging bag, positive valve 6 is communicated with infusion bottle and locks, and drain air in the venous detaining needle, the singlehanded folder of control 5 lockings prolong pipe 2, pinch with hands and to hold needle handle 7 syringe needle 4 is aimed at vein blood vessels, and be the puncture of 15 °～30 ° angles with skin, if the blood back phenomenon occurs in the indwelling needle stand 3 of transparent mode structure, represent that then syringe needle 4 accurately thrusts in the vein blood vessel, reduce angle and again syringe needle 4 is advanced 0.2cm～0.5cm, fixing needle stand 3 and the prolongation pipe 2 kept somewhere opened singlehanded folder 5, infuses.After transfusion finishes, tube sealing need be carried out, syringe needle fill nipple 1 inside of tube-sealing solution (normal saline and heparin liquid normal saline) will be pumped, the withdraw of the needle of tube-sealing solution limit is injected on the limit, after treating that tube-sealing solution enters syringe needle 4, clamp prolongation pipe 2 with singlehanded folder 5, with joint 1 sealing.
Claims (3)
1. novel venous detaining needle, it comprises joint (1), the prolongation pipe (2) that is communicated with the outlet of joint (1), the indwelling needle stand (3) that is communicated with prolongation pipe (2) and is installed in the syringe needle (4) of keeping somewhere needle stand (3) end, it is characterized in that: it also comprises positive valve (6) and singlehanded folder (5), positive valve (6) is fixedly mounted on the porch of joint (1), prolong pipe (2) and be provided with singlehanded folder (5), described indwelling needle stand (3) is the transparent mode structure.
