Detailed Description

The core of the utility model is to provide a prevent special needle of acupuncture implanted device of dosing, have the potential safety hazard of stabbing the operator when having avoided pulling out the needle, improved the operational safety nature.

In order to make the technical field of the present invention better understand, the present invention will be described in detail with reference to the accompanying drawings and the detailed description.

Referring to fig. 1 to 3, fig. 1 is a schematic structural view of a needle dedicated for an anti-needle-prick implantable drug delivery device according to the present invention; FIG. 2 is a schematic structural view of the needle handle, the connecting member and the U-shaped groove in FIG. 1; fig. 3 is a schematic view of another angle of fig. 2.

The utility model provides a special needle of anti-acupuncture implanted device of dosing, including helmet 7, connecting seat 8, hose 9, only flow clamp 10, protective sheath 11, needle tubing 2, needle handle 1, prevent stinging fender spare and connecting piece 4, install needle tubing 2 perpendicularly on the needle handle 1, prevent stinging the fender spare and install the side end face at needle handle 1 through connecting piece 4, and drive through connecting piece 4 and prevent stinging fender spare and move to the direction of being close to or deviating from needle tubing 2 for needle handle 1, also realize the folding upset within the 270 scope, prevent stinging fender spare and needle handle 1 one of two has seted up locking hole 5, the back of the other is equipped with lock post 6, when preventing stinging fender spare folding upset to the back and the back of needle handle 1 pastes mutually, lock post 6 passes locking hole 5 and locks in, and is convenient to take, do not take space; when medical personnel need to pull out the needle tube 2, the anti-puncture blocking piece is lightly buckled to release the connection relation between the lock column 6 and the locking hole 5, and the anti-puncture blocking piece is rotated by about 270 degrees, at the moment, the anti-puncture blocking piece is positioned above the needle tube 2 to protect the medical personnel, and when the needle is pulled out, the medical personnel can be prevented from being punctured by the needle head, so that the operation safety is improved; after the needle head is pulled out, the needle tube 2 is pressed into the anti-puncturing stopper, so that the safety disposal of the special needle is realized.

The anti-prick stopper and the connecting piece 4 are preferably of an integrated structure, and the anti-prick stopper and the connecting piece 4 can be integrally injection-molded, and of course, the anti-prick stopper and the connecting piece 4 can also be in sleeve connection or clamping connection.

Because connecting piece 4 is for the folding motion of needle handle 1, for the convenient connecting piece 4 motion, can set up the folding end (also motion portion) of connecting piece 4 into V type structure, V type pointed end straight line is the folding line, and cuts thin processing, because connecting piece 4 is the working of plastics, can bear connecting piece 4 and buckle the atress and not break.

In addition, the lock column 6 is provided with an inlet end and a locking end, the outer diameter of the inlet end is larger than the inner diameter of the locking hole 5, and the outer diameter of the locking end is smaller than the inner diameter of the locking hole 5, so that when the puncture-proof stopper and the needle handle 1 need to be buckled, the inlet end of the lock column 6 is extruded into the locking hole 5 under the action of external extrusion force to prevent the lock column 6 from falling off; when the connection relation needs to be released, the lock column 6 can be pulled out from the locking hole 5 by applying external force slightly.

In order to fix the needle tube 2 by the anti-puncturing stopper, the anti-puncturing stopper can be provided with a U-shaped groove 31, a clamping piece 32 is arranged in the U-shaped groove 31, the U-shaped groove 31 is used for accommodating the needle tube 2, and the anti-dropping locking of the needle tube 2 is realized by the clamping piece 32.

Particularly, fastener 32 includes connecting portion and elasticity portion that resets, the bottom surface in U type groove 31 is located perpendicularly to connecting portion, elasticity portion that resets locates connecting portion, and set up outside the groove with connecting portion each other becomes the contained angle, because fastener 32 keeps off piece through integrative injection moulding with preventing stinging, consequently, elasticity portion that resets has certain elasticity, under the exogenic action, needle tubing 2 moves and pushes down elasticity portion that resets towards U type groove 31, in the clearance entering groove between elasticity portion that resets and the cell wall, afterwards, elasticity portion that resets moves, block that needle tubing 2 deviates from the inslot.

On the basis of the above embodiment, in order to reduce the debris generated when the needle tip penetrates into the silica gel, the needle tip may be designed to be a bent structure, preferably, an included angle between the needle tip and the needle body is 12 °, and the needle tip is bent to a side away from the needle tip inclined plane, so that the needle tip inclined plane is approximately horizontal to the silica gel during the penetration, thereby reducing the penetration area, and reducing or even avoiding the generation of the debris.

In order to operate the needle handle 1 conveniently, an anti-slip structure can be arranged on the needle handle 1, and the anti-slip structure can be specifically anti-slip concave points, anti-slip bulges or anti-slip lines so as to increase the friction force between the anti-slip structure and a hand and prevent the hand from slipping.

To sum up, the utility model discloses a core lies in, and the design has the stab-resistant fender piece of U type groove 31 to be connected integratively and can fold a motion for needle handle 1 through connecting piece 4 and needle handle 1, form when pulling out the needle and block and to medical personnel's protection to needle tubing 2, the back is extracted to the syringe needle, passes through fastener 32 locking with needle tubing 2 in U type groove 31, reaches the technological effect of avoiding special needle accidental injury medical personnel.

The needle special for the anti-acupuncture implantable drug delivery device provided by the utility model is described in detail above. The principles and embodiments of the present invention have been explained herein using specific examples, and the above descriptions of the embodiments are only used to help understand the method and its core ideas of the present invention. It should be noted that, for those skilled in the art, without departing from the principle of the present invention, the present invention can be further modified and modified, and such modifications and modifications also fall within the protection scope of the appended claims.
