Problems solved by technology

Once the retraction action is too large, the puncture steel needle sticking to the patient's blood will accidentally injure the medical staff, which in turn may cause the medical staff to be infected by the bacteria carried in the patient's blood
In addition, when disposing of discarded puncture needles may also cause staff to be stabbed, causing difficulties in the special treatment of medical waste, thus causing serious social security risks

Embodiment 1

[0022] like figure 1 As shown, the present invention includes a puncture needle holder, the puncture needle holder is tightly connected with the puncture needle, a protective cover is provided at the connection end of the puncture needle holder and the puncture needle, and the protective cover includes telescopic arms on both sides and is fixed to the telescopic arm. Protective glue for connections such as Figure 4 As shown, the telescopic arm includes several cross bars connected head to tail. The cross bar includes two telescopic bars whose middle parts are overlapped and riveted at the overlapping places. The maximum extension length of the protective cover is 0.1-0.5 cm longer than the length of the puncture needle. The outer diameter of the protective rubber is consistent with the inner diameter of the universal indwelling needle holder, and the telescopic arms are arranged on both sides of the puncture needle.

[0023] like figure 2 As shown, in the present invention...

Embodiment 2

[0025] The structural features of this embodiment and embodiment 1 are roughly the same, as Figure 5 As shown, the difference is that: the protective cover includes a lead wire fixedly connected with the puncture needle base and a protective glue fixedly connected with the lead wire, the maximum extension length of the protective cover is 0.1-0.5cm longer than the length of the puncture needle, and the outer surface of the protective glue The diameter is consistent with the inner diameter of the universal indwelling needle seat. The lead wires are arranged on both sides of the puncture needle, and there are at least two lead wires, preferably three or more.

[0026] like Image 6 As shown, in the present invention, after the puncture needle punctures the blood vessel, when the puncture needle is pulled out, since the protective glue is completely inserted into the indwelling needle holder, and the outer diameter of the protective glue is exactly the same as the inner diameter...

Abstract

The invention discloses a safety puncture needle seat for a remaining needle. The safety puncture needle seat comprises a puncture needle seat body, wherein the puncture needle seat body is in fastened connection to a puncture needle; the end, connected to the puncture needle, of the puncture needle seat body is provided with a protective shield; and the protective shield comprises telescopic arms at two sides and protective glues which are fixedly connected to the telescopic arms. The safety puncture needle seat provided by the invention can solve the problem that medical personnel can be infected by germs in patient's blood in the case that the medical personnel is hurt by a puncture steel needle covered with the patient's blood due to a vigorous contraction action in a process of using an existing puncture needle; moreover, the safety puncture needle seat provided by the invention is simple in structure and practical and is applicable to straight and Y-shaped remaining needles; and the safety puncture needle seat is great in market popularization value.

Description

technical field [0001] The invention relates to medical equipment, in particular to a safe puncture needle holder for indwelling needles. Background technique [0002] The venous indwelling needle is a medical device used for intravenous infusion therapy. The venous indwelling needle is easy to operate and is suitable for puncture in any part. It also reduces the pain of repeated puncture for patients and the workload of nurses. Nurses welcome. In clinical use, the puncture needle guides the cannula of the indwelling needle into the vein of the human body. After seeing the return of blood, confirm the success of the venipuncture, withdraw the puncture needle, and only keep the soft indwelling needle sleeve in the vein. The medicinal solution is injected into the human body through the cannula of the indwelling needle. The cannula of the indwelling needle is made of soft and elastic material, which can be used within the safe indwelling time of the human vein, and bends sy...
