Description
Technical Field
The utility model relates to the technical field of medical appliances, in particular to an internal fistula needle which is safe to use.
Background
After hemodialysis treatment, medical staff takes place the acupuncture easily and hinders when pulling out internal fistula needle back cover needle cap, and back cover needle cap often does not put in place and internal fistula needle slippage appears, easily causes the acupuncture to hinder and blood pollutes.
In addition, the existing needle clamping groove can cause the phenomenon of needle head falling off to cause blood to pollute the ground or the surface of articles, and the exposed needle head contacting the blood of a patient can often cause injuries to medical workers and medical waste disposal personnel, thereby causing infection and propagation of blood-borne diseases.
Disclosure of Invention
The utility model aims at providing a safe type internal fistula needle that easy operation, safe and reliable, economical and practical, avoid the emergence that the needle prick hindered to solve above-mentioned problem.
In order to achieve the above purpose, the utility model adopts the technical scheme that:
the utility model provides an internal fistula needle safe in utilization, is including syringe needle, needle wing and the pipe that sets gradually needle wing installation department is provided with the needle wing mounting groove, just be provided with the needle wing tooth of breaking that is used for the needle wing rupture on the needle wing, still includes the safety cover, the safety cover is located the pipe periphery, the safety cover internal diameter is greater than the external diameter of pipe, the interval is provided with first elastic bulge and second elastic bulge in the safety cover, wherein, first elastic bulge is greater than needle wing mounting groove to the terminal distance of syringe needle to the distance that is close to of safety cover.
As a preferred technical scheme: the width of the first elastic bulge is equal to that of the needle wing mounting groove. The first elastic bulge can be better matched with the needle wing installation groove, and the reliability of protection is guaranteed.
As a preferred technical scheme: the distance from the first elastic bulge to the protective cover close to the needle head is larger than the distance from the needle wing mounting groove to the tail end of the needle head. The protective cover may provide longer and more reliable protection.
The utility model discloses a safety cover can remove through external force outside the pipe, when internal fistula needle pulls out, takes off the needle wing through the rupture tooth, exposes the needle wing mounting groove, then removes the safety cover toward the syringe needle direction, and first elastic bulge card is in the needle wing mounting groove, and second elastic bulge still closely laminates with the pipe, forms a safe type safety cover like this, and duplicate protection, and can not drop, has guaranteed to use needle safety.
Compared with the prior art, the utility model has the advantages of: the utility model can not only protect the patient from being stabbed and the comfort level can not be changed when in use, but also protect the medical care personnel from occupational exposure and protect the medical waste disposal personnel; the operation is simple, the protective cover can be sleeved back by one hand after the needle head is pulled out, and the needle head does not fall off; the protective cover can move, so that the comfort of a patient cannot be changed, and pressure sores around the puncture part cannot be caused; the protective cover is arranged, so that economy and practicability are realized, the cost is reduced, and the economic benefit ratio is realized.
Drawings
Fig. 1 is a schematic structural view before protection of the present invention;
FIG. 2 is a schematic view of the needle of FIG. 1 with the needle wing removed;
FIG. 3 is a schematic view of the configuration of the needle wing of FIG. 1;
FIG. 4 is a schematic view of the protective cover of FIG. 1;
fig. 5 is a schematic diagram of a structure for providing protection.
In the figure: 1. a needle head; 2. a needle wing mounting groove; 3. a needle wing; 4. the needle wing breaks the tooth; 5. a protective cover; 6. a first elastic protrusion; 7. a second elastic protrusion; 8. a conduit.
Detailed Description
The present invention will be further explained with reference to the accompanying drawings.
Example (b):
referring to fig. 1 to 5, a safe internal fistula needle comprises a needle head 1, a needle wing 3 and a catheter 8 which are sequentially arranged, wherein a needle wing installation groove 2 is formed at the installation position of the needle wing 3, needle wing breaking teeth 4 for breaking the needle wing 3 are arranged on the needle wing 3, the safe internal fistula needle further comprises a protective cover 5, the protective cover 5 is sleeved on the periphery of the catheter, the inner diameter of the protective cover 5 is larger than the outer diameter of the catheter 8, and first elastic bulges 6 and second elastic bulges 7 are arranged in the protective cover 5 at intervals, in the embodiment, the distance from the first elastic bulges 6 to the protective cover 5, which is close to the needle head 1, is larger than the distance from the needle wing installation groove 2 to the tail end of the needle head 1; the width of the first elastic bulge 6 is equal to that of the needle wing mounting groove 2;
in this embodiment, the total length of the needle 1 is 4cm, wherein the width of the needle wing mounting groove 2 is 1cm, and correspondingly, the width of the first elastic protrusion 6 is also equal to or slightly less than 1cm, so that when the protective cover 5 is pushed towards the needle direction, the first elastic protrusion 6 better enters the needle wing mounting groove 2 and is clamped firmly, the length of the remaining part of the needle 1 is 3cm, and the total length of the protective cover 5 is 5.5cm, as shown in fig. 4, wherein the distance from the end part close to the needle 1 to the end part of the first elastic protrusion 6 is about 4cm, that is, a protection margin of about 1cm is provided for the end of the needle 1, thereby preventing safety accidents caused by puncture.
The above description is only exemplary of the present invention and should not be taken as limiting the scope of the present invention, as any modifications, equivalents, improvements and the like made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
