Abstract
The utility model discloses a puncture needle with a protective sleeve, comprising a needle head and a puncture needle blood-collecting tube, wherein the needle head is detachably fixed at one end of the puncture needle blood-collecting tube. The puncture needle with the protective sleeve is characterized by also comprising a puncture needle protective sleeve provided with a through hole through which the puncture needle blood-collecting tube can penetrate; and the tail end of the puncture needle blood-collecting tube, on which the needle head is fixed, is provided with a fixing device for preventing the protective sleeve from falling, and the length of the puncture needle protective sleeve is a little longer than the distance from the fixing device to the tail end of the needle head. After the dialysis operation for a patient is finished, the exposed needle head of the puncture needle with the protective sleeve can be hidden in the protective sleeve, thereby preventing medical workers from being punctured by the discarded puncture needle during the treatment thereof and being safer.
Description
Technical field
This utility model belongs to the medical treatment consumptive materials technical field, especially relates to a kind of puncture needle that has protective sleeve.
Background technology
The uremia of treatment at present comparatively effectively means is to carry out hemodialysis, in blood dialysis, need use the syringe needle that length uses than normal injection and grow the special-purpose syringe needle of a lot of punctures.This type of syringe needle is disposable use mostly, directly abandons after the use, exposed syringe needle is not increased safeguard procedures.Medical personnel are carrying out in the puncture for treating process patient, and fetching syringe needle need be very careful, otherwise exist by the danger of needle sting; When especially medical personnel handle Biohazard Waste, stabbed by exposed needle point easily especially.
The utility model content
The purpose of this utility model is to provide a kind of puncture needle that has protective sleeve, and after patient dialysed end, exposed syringe needle can be hidden in the protective sleeve, for user provides safer protection, solves the defective that prior art exists.
For achieving the above object, this utility model adopts following technical scheme:
A kind of band protective sleeve puncture needle comprises syringe needle, puncture needle blood taking tube, dismountable puncture needle blood taking tube one end that is fixed in of described syringe needle; Also comprise the puncture needle protective sleeve; this protective sleeve is provided with the transparent through hole of puncture needle blood taking tube; puncture needle blood taking tube fixed needle end is provided with a fixture that prevents the protective sleeve landing, and the length of described puncture needle protective sleeve slightly is longer than the distance of fixture to the syringe needle end.
Preferred scheme is: described fixture is one to be fixed in the symmetrical butterfly fin of puncture needle blood taking tube fixed needle end.
More preferred scheme is: described puncture needle protective sleeve is provided with butterfly fin draw-in groove, and this draw-in groove and butterfly fin are complementary.
More preferred scheme is: described puncture needle protective sleeve outer face is provided with anti-skidding stricture of vagina.
This utility model compared with prior art has following advantage and beneficial effect:
After this utility model puncture needle blood taking tube passes protective sleeve by puncture needle protective sleeve through hole; be provided with fixedly butterfly fin of protective sleeve at the first end of puncture needle blood taking tube locking pin; simultaneously be provided with the turning formula draw-in groove that is complementary with the butterfly fin at the protective sleeve end; can not only effectively prevent the protective sleeve landing; can also play a kind of fixation to protective sleeve; the length of protective sleeve slightly is longer than the length of syringe needle, makes firm syringe needle is hidden in the protective sleeve of protective sleeve.The puncture needle of band protective sleeve described in the utility model, under the state of use useless, syringe needle is hidden in the protective sleeve, makes when medical personnel fetch puncture needle or processing garbage, has avoided being punctured the danger of pricking wound, and is safer.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the structural representation of this utility model puncture needle protective sleeve.
The specific embodiment
Below in conjunction with the drawings and specific embodiments this utility model is described in further details.
As shown in Figure 1 and Figure 2, a kind of preferred embodiment comprises a kind of band protective sleeve puncture needle, comprises syringe needle 1, puncture needle blood taking tube 3, syringe needle 1 dismountable puncture needle blood taking tube 3 one ends that are fixed in; After the through hole 42 of puncture needle blood taking tube 3 by puncture needle protective sleeve 4 ends penetrates puncture needle protective sleeve 4; be provided with a symmetric butterfly fin 2 that prevents the protective sleeve landing at puncture needle blood taking tube 3 fixed needle ends; be provided with near through hole 42 1 ends at puncture needle protective sleeve 4 and can supply the fixed draw-in groove 41 of butterfly fin; this draw-in groove 41 is complementary with butterfly fin 2. and puncture needle protective sleeve 4 outer faces are provided with the anti-skidding stricture of vagina 41 of landing when preventing to fetch; the length of puncture needle protective sleeve 4 slightly is longer than the distance of fixture to the syringe needle end; under the state of puncture needle use useless, syringe needle is hidden in the protection groove 43 of puncture needle protective sleeve.
In concrete enforcement, the protective sleeve entire length can be designed as the protective sleeve that length is 50～60mm, and the puncture needle syringe needle of this moment is long about 40mm, and in patient's end of dialysing, when abandoning syringe needle, protective sleeve just can cover whole syringe needle.Butterfly wing draw-in groove is designed to corner style, prevents that protective sleeve from sliding, and plays a protective role.Handle knob the position according to the hand-type design, comfortable feel, anti-skidding.
Above content is to further describing that this utility model is done in conjunction with concrete preferred implementation; for this utility model person of an ordinary skill in the technical field; under the prerequisite that does not break away from this utility model design; the some simple deduction or replace of making all are considered as belonging to protection domain of the present utility model.
