Abstract

The utility model discloses a remaining needle, which comprises a three-way piece, a hose, a pipe holder, a remaining pipe, a needle bed and a steel needle, wherein the remaining pipe is installed below the pipe holder; the steel pipe is fixed on the needle bed and is arranged in the remaining pipe; the output end of the hose is connected with a skew joint on the side surface of the pipe holder; and a filter device is connected between the output end which is a lower port of the three-way piece and the input end of the hose. Because the filter device is arranged between the three-way piece and the hose, impurities in the liquid medicine are isolated by the filter device to effectively prevent the impurities from entering the remaining pipe so as to avoid from hurting a human body.

Description

Remaining needle

Technical field

This utility model relates to a kind of medical device, relates in particular to the remaining needle that a kind of venipuncture is used.

Background technology

Venipuncture is widely used in remaining needle in the middle of the clinical treatment, and it can alleviate the patient because of the pain that repeatedly venipuncture produces, and the workload that can alleviate medical personnel is arranged simultaneously.

Existing remaining needle generally includes three-way piece, flexible pipe, needle stand, draw point, indwelling tube and base, and two upper openings of three-way piece are installed calparine cap and end cap respectively, and flexible pipe is with the lower openings of three-way piece and the lateral opening conducting of base; Indwelling tube is installed in the base bottom, and draw point is fixed on the needle stand, during use; Draw point is inserted in the indwelling tube and makes the bottom of draw point pass the lower end of indwelling tube; At this moment, needle stand is fitted in the open upper end place of base, afterwards draw point is detached from indwelling tube; Medicinal liquid enters into indwelling tube and is injected into human vein via flexible pipe through the three-way piece input.Yet in use, the medicinal liquid of importing through three-way piece is directly to enter into human vein, and the impurity that exists in the medicinal liquid enters into human vein immediately, can damage human body.

The utility model content

To the deficiency of prior art, the purpose of this utility model is intended to provide a kind of remaining needle, and it can carry out filtration, purification to medicinal liquid through setting up defecator before medicinal liquid gets into human vein.

For realizing above-mentioned purpose, this utility model adopts following technical scheme:

Remaining needle; Comprise three-way piece, flexible pipe, base, indwelling tube, needle stand and draw point; Indwelling tube is installed in the base below; Draw point is fixed on the needle stand and places in the indwelling tube, and the outfan of flexible pipe connects the lateral angle stake of base, and the lower port of three-way piece is as also being connected with a defecator between the input of its outfan and flexible pipe.

Defecator comprise with the integrated loam cake of three-way piece, through being threaded in loam cake below lower cover and be arranged in loam cake and the filter of the inner chamber that lower cover forms, this filter is folded between the roof of upper end and loam cake of lower cover.

Top two openings of three-way piece are separately installed with calparine cap and end cap.

The outer setting of flexible pipe has flow-stopping clip.

The beneficial effect of this utility model is:

Because a defecator is set between three-way piece and flexible pipe, the impurity in the medicinal liquid is filtered device isolates, and can prevent effectively that impurity from entering into indwelling tube, thereby avoid the injury of impurity to human body.

Fig. 2 is the scheme of installation of remaining needle shown in Figure 1;

Fig. 3 is the cutaway view of defecator among Fig. 2;

Fig. 4 is the structural representation of the another kind of remaining needle of this utility model.

The specific embodiment

Below, in conjunction with the accompanying drawing and the specific embodiment, this utility model done further describing:

Like Fig. 1,2, shown in 3; Be a kind of remaining needle of this utility model, it comprises three-way piece 1, flexible pipe 3, base 6, indwelling tube 7, needle stand 4, draw point 5 and defecator 2, and the underpart opening of three-way piece 1 is as its outfan; Defecator 2 is installed between the input of outfan and flexible pipe 3 of three-way piece; The outfan of flexible pipe 3 then is connected on the inclined tube mouth 61 that stretches out base 6 sides, the lower end that indwelling tube 7 is installed base 6, and draw point 5 is fixed on the needle stand 4 and places indwelling tube 7.

Defecator 2 comprises loam cake 21, lower cover 22; And filter 23; Loam cake 21 is in the same place through being threaded with lower cover 22, and forms an inner chamber between the two at it, and filter 23 is placed in this inner chamber; Loosening in order to prevent filter 23, can filter 23 be installed between the roof and lower cover 22 upper ends of loam cake 21; Filter 23 adopts general filtering material to be made.

Two openings in the top of three-way piece 1 are separately installed with calparine cap 11 and end cap 12.Flexible pipe 3 is provided with a flow-stopping clip 8, in the time need not infusing, can flexible pipe 3 be clamped.

Medicinal liquid via three-way piece 1 output filters through filter 23, can prevent that impurity from entering into indwelling tube 7, thereby in injection process, guarantees that the medicinal liquid that enters into human vein has higher cleanliness factor.

As shown in Figure 4, for the ease of processing and fabricating, the loam cake of defecator and three-way piece can be the branch body structures.

For a person skilled in the art, can make other various corresponding changes and distortion, and these all changes and distortion should belong within the protection domain of this utility model claim all according to the technical scheme and the design of above description.
