Specific embodiment
The present invention is described in detail for shown each implementation method below in conjunction with the accompanying drawings, but it should explanation, these Implementation method not limitation of the present invention, those of ordinary skill in the art according to these implementation method institutes works energy, method, Or equivalent transformation or replacement in structure, belong within protection scope of the present invention.
As shown in figure 1, continuous positive pressure remaining needle of the invention includes:Remaining needle, conduit 11 and malleation keep component.
As shown in Figure 1,5, the remaining needle includes needle stand 1, deck 2, draw point 7, and one end of the draw point 7 is installed on described On needle stand 1, the deck 11 is set on the draw point 7, and shell fragment 9 is provided with the deck 2.The shell fragment 9 is used to work as steel Pin 7 is extracted and stayed at needle point, so as to prevent draw point from stabbing medical personnel.Further, it is also equipped with conduit on the draw point Seat 3, metal wedge 4, batching pig 8.Additionally, FEP pipes 5 or PU pipes are provided with the needle body that is externally exposed of the draw point 7, and it is described Remaining needle also includes sheath 6, and what the draw point was externally exposed is partially housed in the sheath 6.
The remaining needle also has branch pipe, and the branch pipe is connected with one end of the conduit 11, the conduit 11 it is another One end keeps component to be connected with the malleation.Wherein, one-hand clip 10 or flow stopping device are provided with the conduit 11.By described One-hand clip 10 can be controlled to the transfusion of the remaining needle, when stopping infusion is needed, the one-hand clip 10 be clamped, so that Close the infusion channel of the formation of the conduit 11.
The malleation keeps component to cause remaining needle when not infusing, and can continue to injecting micro physiology in patient vessel Salt solution, it is to avoid blood backflow and the generation of solidification phenomenon in indwelling needle catheter, so as to reducing thrombus shape in indwelling needle catheter Into risk.
As shown in Fig. 2 specifically, the malleation holding component includes:Silicone tube 15, feed liquor check valve 16, liquid valve 17 And joint 12.Wherein, the silicone tube 15 has elasticity, and volumetric expansion during its internal filled liquid, the silicone tube 15 passes through institute State feed liquor check valve 16 to be connected with the liquid feeding end of the joint 12, the silicone tube 15 is connect by the liquid valve 17 with described First 12 outlet end is connected, and the joint 12 is connected with the other end of the conduit 11 simultaneously.
Preferably, the joint 12 can be the one kind in color threeway, color two-way, straight type positive pressure connector.Additionally, described connect First 12 can also be Y shape positive pressure connector.When the joint 12 is color threeway, the color threeway has calparine cap 18 and resistance cap 19 can puncture cap.
As shown in Figure 3,4, alternatively, the joint 12 also can be used as connector, now, the company Fitting is connected with the one kind in color threeway 18-1, color two-way 18-2, positive pressure connector.The positive pressure connector can be Y shape malleation Joint 18-3, or straight positive pressure connector 18-4.Alternately, the connector can also be with Y type capsule positive pressure connectors 18-5 or straight type capsule positive pressure connectors 18-6 is connected.Wherein, when the joint 12 is connected with color threeway, the color threeway Cap 20 or cap can be punctured with calparine cap 19 and resistance.
So as to when the malleation keeps component to use, be injected in the silicone tube 15 by feed liquor check valve 16 first Physiological saline, with the injection of the physiological saline, the silicone tube 15 gradually expands, and gradually becomes spherical by olive shape.When After physiological saline injection is finished, liquid valve 17 is opened.Because the silicone tube 15 has elasticity, so that the silicone tube 15 has Recover to the trend of original state, and then gradually flowed out from liquid valve 17 by physiological saline that elastic force extrudes its inside.So as to, In remaining needle stopping infusion, under the supply of enough physiological saline, can keep thering is physiological saline to flow all the time, anti-Hemostatic Oral Liquid Flow backwards and solidify, the formation of anti-tampon.
Further, for the ease of the installation of the silicone tube 15, the malleation keeps component also including tube core 14, described Tube core 14 is located in the silicone tube 15, and the two ends of the silicone tube 15 are connected with the lateral wall of the tube core 14.Further Ground, offers through hole on the tube core 14, the tube core 14 is connected by the through hole with the silicone tube 15.Now, institute One end that feed liquor check valve 16 is arranged at the tube core 14 is stated, the liquid valve 17 is arranged at the other end of the tube core 14.From And, the physiological saline of injection is from from the feed liquor check valve 16, the entrance silicone tube 15 of tube core 14 and further certainly described In silicone tube 15, in flowing into the conduit 11 from the liquid valve 17.
In above-mentioned implementation method, in order to avoid impurity flow into human vas in, be additionally provided with filter membrane in the tube core 14 13, the filter membrane 13 is located at the import of the liquid valve 17.So as to the physiological saline flowed into the conduit 11 enters first The filtering of the filter membrane 13 is crossed, in then flowing into the conduit 11 by the liquid valve 17, and further passes through remaining needle Into in the blood vessel of human body.Meanwhile, by setting the filter membrane 13 air can also discharged, and liquid cannot flow out.
In sum, continuous positive pressure remaining needle of the invention keeps component by setting malleation so that remaining needle is not defeated During liquid, can continue to injecting micro physiological saline in patient vessel, it is to avoid blood backflow and solidification are existing in indwelling needle catheter The generation of elephant, so as to reduce thrombotic risk in indwelling needle catheter.
It is obvious to a person skilled in the art that the invention is not restricted to the details of above-mentioned one exemplary embodiment, Er Qie In the case of without departing substantially from spirit or essential attributes of the invention, the present invention can be in other specific forms realized.Therefore, no matter From the point of view of which point, embodiment all should be regarded as exemplary, and be nonrestrictive, the scope of the present invention is by appended power Profit requires to be limited rather than described above, it is intended that all in the implication and scope of the equivalency of claim by falling Change is included in the present invention.Any reference in claim should not be considered as the claim involved by limitation.
Moreover, it will be appreciated that although the present specification is described in terms of embodiments, not each implementation method is only wrapped Containing an independent technical scheme, this narrating mode of specification is only that for clarity, those skilled in the art should Specification an as entirety, the technical scheme in each embodiment can also be formed into those skilled in the art through appropriately combined May be appreciated other embodiment.
