Abstract
The utility model provides a hypodermic creeping needle tubing kit which comprises a needle tubing with scales and a needle core sleeved in the needle tubing, wherein a bending head in an arc structure is arranged at the front end of the needle tubing, the bending head is of a blunt arc-shaped and needle-shaped structure, and the head end of the needle core is sharp. The hypodermic creeping needle tubing kit has the advantages that structural design is simple, hypodermic creeping operation is convenient in the process of puncturing of the needle tubing, subcutaneous tissues and blood vessels are evaded effectively, and wounds generated in the process of puncturing are decreased.
Description
Technical field
This utility model relates to a kind of medical device, especially a kind of subcutaneous needle tubing external member of moving under water.
Background technology
At present, the deep vein puncture central venous catheter is widely used in the severe crisis patient rescues, the internal jugular vein traveling is straight, high by way of the central venous catheter puncture success rate through this, few intercurrent disease, but conventional puncture fixation is easy to come off and easy generative center venous duct dependency bloodstream infection.Move under water under the percutaneous and set up hypodermic tunnel and put the generation that the method for pipe can well reduce this complication.But in clinical research or treatment, move under water under the percutaneous and set up hypodermic tunnel and put the method for pipe and still have problems, do not have the subcutaneous operation of moving under water of special needle tubing to be not easy successfully, large to subcutaneous tissue injury during operation.
The utility model content
This utility model will solve the shortcoming of above-mentioned prior art, and a kind of subcutaneous needle tubing external member of moving under water is provided, and it is simple in structure, can make subcutaneous simple to operateization of moving under water after the application, and wound is little.
This utility model solves the technical scheme that its technical problem adopts: this subcutaneous needle tubing external member of moving under water, comprise needle tubing and the nook closing member that is enclosed within the needle tubing with rule, the front end of needle tubing is provided with bending head, and bending head is stubbed arc aciculiform structure, and the nook closing member head end is sharp keen.Bending head and stubbed arc aciculiform structure can be avoided subcutaneous tissue and blood vessel, have reduced the wound that the subcutaneous puncture of moving under water produces.This external member is equally applicable to the medical skill of other operation of need to moving under water in the clinical treatment.
For further perfect:
Wherein the overall diameter of bending head external port is less than the overall diameter of needle tubing.The overall diameter of bending head external port reduces, and has reduced front end puncture area, has further reduced the wound that the needle tubing puncture produces.
Wherein the tube wall of bending head is by gradually attenuation outside interior.Be conducive to like this reduce the overall diameter size of bending head front end, and do not affect the interior hole size at bending head place.
Wherein the Way out of bending head and the angle between the needle tubing are 70 °～90 °.In this angular range, be conducive to avoid subcutaneous tissue and blood vessel.
After nook closing member was inserted in needle tubing, the sharp keen head end of nook closing member front end grew needle tubing mouth 0.5cm, passed smoothly prick skin of needle tubing mouth after reaching the skin collar extension moving under water.
The effect that this utility model is useful is: this utility model structural design is simple, and the needle tubing external member makes the subcutaneous more convenient operation of moving under water in the process of puncture, and has effectively avoided subcutaneous tissue and blood vessel, has reduced the wound that produces in the piercing process.The medical skill of other operation of need to moving under water is fit to use this external member equally in the clinical treatment.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Description of reference numerals: needle tubing 1, bending head 2, nook closing member 3.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing:
With reference to accompanying drawing: this subcutaneous needle tubing external member of moving under water, comprise with the needle tubing 1 of rule and be enclosed within nook closing member 3 in the needle tubing 1, the front end of needle tubing 1 is provided with bending head and stubbed arc aciculiform structure 2.The overall diameter of bending head 2 external port is less than the overall diameter of needle tubing 1.Wherein the tube wall of bending head 2 is by gradually attenuation outside interior.Wherein the angle a between the Way out of bending head 2 and the needle tubing 1 is 70 °～90 °.
Puncture according to a conventional method during internal jugular vein puncture send guide wire success after, cut an about 0.5cm osculum (put manage successfully after a pin sew up) along point of puncture skin, with the subcutaneous needle tubing external member of moving under water from the vertical about 3cm～5cm of subcutaneous moving under water (tracheotomy patients mastoid process direction behind the ear is moved under water) behind the neck of point of puncture, with passing needle tubing 1 after nook closing member 3 prick skin, guide wire is pulled out skin from needle tubing 1, withdraw from the subcutaneous needle tubing 1 that moves under water, then insert central venous catheter by guide wire, suture needle fix and with aseptic from the glutinous covering point of puncture of applying ointment or plaster.
Although this utility model illustrates and describes by the reference preferred embodiment,, those skilled in the art should understand, and in the scope of claims, can do the various variation on form and the details.
