Detacher for disposable insulin pen needle

Technical Field

The utility model relates to the field of medical equipment, concretely relates to a detacher for disposable insulin pen syringe needle.

Background

At present, the number of patients suffering from diabetes mellitus in the clinic is increasing, the diabetes mellitus is also a chronic progressive disease, insulin injection is one of important measures for controlling blood sugar of diabetics, and especially the insulin injection of hospitalized patients needs to be operated by nursing staff. The use of disposable insulin needles has problems, such as needle stick injuries, while facilitating the injection procedure. At present, the original needle cap of the insulin needle is sleeved back and then the needle is taken down clinically, and due to the disassembly mode, the hand of an operator can contact the used insulin needle in a short distance, so that the probability of needle stick injury is improved; the hand-eye coordination of some old people is reduced, the risk of needle stick injury can be caused during self-operation, and hidden dangers are increased for workers and patients.

SUMMERY OF THE UTILITY MODEL

For solving exist not enough among the prior art, the utility model provides a detacher for disposable insulin pen syringe needle, simple structure, convenient operation has avoided the direct contact of staff with the syringe needle, greatly reduced the stab risk.

The utility model discloses a solve the technical scheme that its technical problem adopted and be: a detacher for a disposable insulin pen needle comprises a handle with an inner cavity and a piston rod movably connected in the cavity of the handle; the top end of the piston rod extends out of the top of the handle and is positioned at the part inside the handle, the outer wall of the piston rod is sleeved with a spring, one end of the spring is fixedly connected with the inner wall of the top of the handle, and the other end of the spring is fixedly connected with the outer wall of the lower part of the piston rod; the piston rod bottom fixedly connected with syringe needle ejecting portion, the handle bottom is inwards sunken to be offered the draw-in groove that is used for joint insulin pen syringe needle.

Furthermore, the needle head ejecting part is inwards sunken to be provided with a sharp needle accommodating cavity.

Furthermore, the top end of the piston rod is connected with a pressing plate, and a limiting plate arranged on the outer wall of the piston rod is further arranged below the pressing plate.

Furthermore, the height of the sharp needle accommodating cavity is greater than the length of the sharp needle part of the insulin pen needle head, so that the top end of the sharp needle part is not contacted with the inner wall of the top part of the sharp needle accommodating cavity when the bottom plane of the ejection part of the needle head is contacted with the top plane of the insulin pen needle head.

Furthermore, the detacher is made of medical plastics.

Has the advantages that: 1. the problem of puncture injury easily caused by sleeving a needle cap back and directly pushing out the needle head in the prior art is solved, the contact rate of the hand and the needle head is greatly reduced, and the occurrence probability of puncture injury accidents is effectively reduced;

2. the needle head ejection part is provided with a corresponding sharp needle accommodating cavity for storing the needle head, so that the contact between the detacher and the sharp needle is avoided, the service life of the detacher is prolonged, and the detacher is more sanitary;

3. the range of the selectable materials of the detacher is wide, and different materials can be selected according to different economic degrees;

4. the detacher can be recycled, and can be used for carrying out sterilization by a most basic 75% alcohol wiping method or selecting a proper sterilization method according to different materials;

5. the detacher is simple and safe to use and does not need special training.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention clearer, the present invention will be described in detail with reference to the accompanying drawings and specific embodiments.

Example 1

The detacher for the disposable insulin pen needle comprises a handle 1 with an inner cavity and a piston rod 2 movably connected in the cavity of the handle 1; the top end of the piston rod 2 extends out of the top of the handle 1 and is connected with a pressing plate 6, and a limiting plate 7 arranged on the outer wall of the piston rod 2 is further arranged below the pressing plate 6. The piston rod 2 is positioned at the part inside the handle 1, the outer wall of the piston rod is sleeved with a spring 3, one end of the spring 3 is fixedly connected with the inner wall of the top of the handle 1, and the other end of the spring is fixedly connected with the outer wall of the lower part of the piston rod 2; the bottom of the piston rod 2 is fixedly connected with a needle head ejecting part 4, and the middle part of the needle head ejecting part 4 is inwards sunken to be provided with a sharp needle accommodating cavity 4.1. The bottom of the handle 1 is inwards sunken to be provided with a clamping groove 5 for clamping a syringe needle of an insulin pen.

Preferably, the height of the sharp needle containing cavity 4.1 is larger than the length of the sharp needle part of the insulin pen needle head, so that the top end of the sharp needle part is not contacted with the inner wall of the top of the sharp needle containing cavity 4.1 when the bottom plane of the needle head ejecting part 4 is contacted with the top plane of the insulin pen needle head.

Preferably, the detacher is made of medical plastics, and can be made of PVC, PE, PP and the like.

During the use, because 5 internal diameters of draw-in groove and insulin pen syringe needle external diameters cooperate, it fixes insulin pen syringe needle and makes it can not deviate from, there is mobilizable piston rod 2 handle 1 inside and piston rod 2 is connected to the outside pressing plate 6 in handle top, handheld handle 1 entangles insulin pen syringe needle with draw-in groove 5, turn round insulin pen syringe needle down and make its joint in draw-in groove 5, then promote downwards and make piston rod 2 drive syringe needle ejecting portion 4 and do ejecting action to insulin pen syringe needle direction according to pressing

plate

6, 4 bottom planes of syringe needle ejecting portion contact with insulin pen syringe needle top plane so that insulin pen syringe needle drops to sharp machine box in, ejecting action is accomplished the back, piston rod 2 automatic re-setting under spring 3's elastic action, make things convenient for next direct use.

The utility model discloses can make staff and patient oneself more convenient, take off safely used insulin pen syringe needle, the design of handle 1 has increased the contact range of operator with the syringe needle, has realized the zero contact of insulin pen syringe needle after operator and the use to do not relate to the required higher accurate nature requirement of the original insulin needle cap of back cover, thereby reduced the danger that the operator was hindered by the needle prick.

The above description is only the specific implementation manner of the preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art can substitute or change the technical solution of the present invention and the design of the present invention within the technical scope of the present invention.
