Abstract
The utility model discloses a negative pressure type retention needle including a syringe needle (2), a horizontal liquid inlet pipe (6) and a slant liquid inlet pipe (3), wherein the horizontal liquid inlet pipe (6) and the slant liquid inlet pipe (3) are communicated with each other in a crossing manner, the syringe needle (2) and the horizontal liquid inlet pipe (6) are connected through a soft pipe, and a negative pressure device (1) is arranged on the external side of the slant liquid inlet pipe (3). Due to suction function of negative pressure, the negative pressure type retention needle, compared with a conventional retention needle, makes an operator see blood returning in time, thereby enabling the operator accurately grasp needle feeding time, effectively improving success rate of puncture, and shortening puncture time. In this way, the negative pressure type retention needle can save time and give better chance for saving a patient, and is suitable for clinic promotion.
Description
Technical field
This utility model belongs to a kind of medical supplies, relates generally to a kind of medical negative-pressure type remaining needle.
Background technology
Hospital clinical runs into emergencies such as critical patients such as shock and serious dehydration through regular meeting, the primary key measure that first aid need be taked is to set up the timely medication of venous channel rapidly.In order to infuse conveniently, utilize remaining needle to infuse usually.Traditional remaining needle mainly is made of syringe needle, horizontal feed tube and oblique feed tube, and horizontal feed tube and oblique feed tube intersection UNICOM pass through hose connection between syringe needle and the horizontal feed tube.Yet the state of an illness is more critical, and circulation is just poorer, often can't see blood back with traditional remaining needle when having an acupuncture treatment to the patient, can't judge the effect of its puncture, and puncture causes big difficulty to clinical vein, is unfavorable for racing against time for rescue work.
Summary of the invention
The purpose of this utility model provides a kind of negative-pressure type remaining needle that can effectively improve the puncture rate.
The purpose of this utility model can adopt following technical scheme to realize: it comprises syringe needle, horizontal feed tube and oblique feed tube, horizontal feed tube and oblique feed tube intersection UNICOM, by hose connection, be provided with negtive-pressure implement between syringe needle and the horizontal feed tube in oblique feed tube outer end.
Described flexible pipe is provided with the clip that is used for grip both hose.
This utility model is because the swabbing action of negative pressure, compares with traditional remaining needle to make the operator see blood back in the very first time, thereby accurately grasps the pin opportunity sent, effectively improve puncture success rate, shorten the puncture time, strive for opportunity, suit at clinical application for saving the patient.
Description of drawings
Accompanying drawing 1 is a structural representation of the present utility model.
Among the figure: 1 negtive-pressure implement, 2, syringe needle, 3, oblique feed tube, 4, pinhead handle, 5, needle tubing, 6, horizontal feed tube, 7, flexible pipe, 8, two pipe infalls, 9, clip.
The specific embodiment
In conjunction with the accompanying drawings, specific embodiment of the utility model is described.
As shown in Figure 1: described negative-pressure type remaining needle comprises syringe needle 1, needle tubing 5, pinhead handle 4, horizontal feed tube 6 and oblique feed tube 3, horizontal feed tube 6 and oblique feed tube 3 are in two pipe infalls, 8 UNICOMs, connect by flexible pipe 7 between syringe needle 2 and the horizontal feed tube 6, be provided with negtive-pressure implement 1 in oblique feed tube 3 outer ends.Described flexible pipe 7 is provided with the clip 9 that is used for grip both hose.
During use, before puncture, press negtive-pressure implement 1, clamp flexible pipe 7, make to form relative vacuum in the flexible pipe 7, help negative pressure and keep with clip 9.During puncture, clip is unclamped, negative pressure exists in syringe needle enters the time that skin do not reach blood vessel, in case needle point thrusts blood vessel, because the negative pressure-pumping effect makes the operator see blood back in the very first time, thereby accurately grasp the pin opportunity sent, effectively improve puncture success rate.
Claims (2)
1. negative-pressure type remaining needle, comprise syringe needle (2), horizontal feed tube (6) and oblique feed tube (3), horizontal feed tube (6) and oblique feed tube (3) intersection UNICOM, connect by flexible pipe (7) between syringe needle (2) and the horizontal feed tube (6), it is characterized in that: be provided with negtive-pressure implement (1) in oblique feed tube (3) outer end.
2. negative-pressure type remaining needle according to claim 1 is characterized in that: described flexible pipe (7) is provided with the clip (9) that is used for grip both hose.
