Description
Technical field:
This utility model relates to a kind of internal fistula pin that has defencive function.
Background technology:
The internal fistula pin is to apply to indispensable medical apparatus and instruments in the hospital clinical hemodialysis operation, and existing internal fistula needle construction is as shown in Figure 1, is made up of tube for transfusion 01, needle tubing 02 and pad 03; And whole internal fistula pin all is exposed fully before and after using; After being used to complete, owing to do not have protector, outside needle tubing 02 is exposed to; So make medical personnel and patient clear up, receive needle stick injury easily when discarding, and cause pollution and infection.
Summary of the invention:
The purpose of this utility model is in order to overcome the shortcoming of above-mentioned prior art, a kind of internal fistula pin that has defencive function of avoiding the accidental puncture related personnel to be provided.
The goal of the invention of this utility model can realize through following technical scheme: a kind of internal fistula pin that has defencive function; Include tube for transfusion, needle tubing and pad, tube for transfusion is connected with needle tubing, and pad is located at the rear end of needle tubing; At the tube for transfusion upper sliding sleeve sheath is arranged; The length of sheath is longer than needle tubing, on sheath, has chute, and pad and chute cunning are joined.
Be provided with at the end of chute that width is bigger than chute, the location notch hole of length and pad coupling.
On the outside wall surface of sheath, be provided with anti-skidding muscle.
After adopting the present technique scheme, the beneficial effect of this utility model is: medical personnel and patient after the clinical use in cleaning, can promote sheath when discarding and entangle needle tubing fully, thereby avoid related personnel's accident to receive the secondary needle stick injury and cause infection.
Description of drawings:
Fig. 1 is the structure chart of prior art internal fistula pin;
Structural representation when exposing needle tubing after the sheath that Fig. 2 has a defencive function internal fistula pin for this utility model slides backward;
Fig. 3 has the structural representation of sheath when front slide protection needle tubing of defencive function internal fistula pin for this utility model.
The specific embodiment:
Below in conjunction with accompanying drawing present technique is described further.
The internal fistula pin that has defencive function includes tube for transfusion 1, needle tubing 2 and pad 3, and tube for transfusion 1 is connected with needle tubing 2, and pad 3 is located at the rear end of needle tubing 2; At tube for transfusion 1 upper sliding sleeve sheath 4 is arranged; The length of sheath 4 is longer than needle tubing 2, on sheath 4, has chute 5, pad 3 and 5 sliding joining of chute; The location notch hole 6 that be provided with at the end of chute 5 that width is 5 bigger than chute, length and pad 3 matees; On the outside wall surface of sheath 4, be provided with anti-skidding muscle 7, it is to produce when medical personnel hold sheath 4 for ease to slide that anti-skidding muscle 7 is set, and improves to promote the reliability that sheath 4 slides.
During normality (before using), needle tubing 2 is outer being exposed at outside the sheath 4, and is as shown in Figure 2; The syringe needle part can lunge carries out hemodialysis in the patient body, behind the completion dialysis treatment, pull out needle tubing 2; Promotion sheath 4, is wrapped up by sheath 4 up to whole needle tubing 2 to front slide (promptly sliding to needle tubing 2) along tube for transfusion 1 again, and is as shown in Figure 3; This encapsulation process, pad 3 slides along chute 5, and sheath 4 wraps the needle tubing 2 back needle tubing 2 unexpected secondaries that just can prevent and stabs medical personnel and patient; Pad 3 slided into location notch hole 6 and positioned this moment, guaranteed that sheath 4 remains the state of protection needle tubing 2.
The above only is the preferred embodiment of this utility model, is not this utility model is done any pro forma restriction.Any those of ordinary skill in the art; Do not breaking away under this utility model technical scheme scope situation; All the method for above-mentioned announcement capable of using and technology contents are made many possible changes and modification to this utility model technical scheme, or are revised as the equivalent embodiment of equivalent variations.So every content that does not break away from this utility model technical scheme, the equivalence of doing according to shape, structure and the principle of this utility model changes, and all should be covered by in the protection domain of this utility model.
