Abstract

The invention discloses a device capable of restraining injection needle cross infection. The device is composed of a needle tip sleeve, a needle tip, a needle base, a lug, a 6:100 taper hole, a thin part, a hook table, a locating hook, a left stop bar, a right stop bar, a clamping groove, a hook sheet, a drag hook, a safety cover and a safety cover plane. The device is provided with the hook sheet and the drag hook, the safety cover can be turned over by an injector to enable the drag hook to hook the hook sheet, and therefore the safety cover plane and a hook table plane are one horizontal plane; after medicine solution or injection or blood drawing is finished, the safety cover is turned over in the needle tip direction till the locating hook hooks the hook table, and the needle tip is locked into the safety cover by the left stop bar and the right stop bar at the moment. The device has the advantages that the hook sheet and the drag hook can be hooked and separated in the overturning process, mold manufacturing is easy, production efficiency is high, and the device has stronger competitiveness.

Description

A kind of device that can suppress entry needle cross infection

Technical field

The present invention relates to a kind of device that can suppress entry needle cross infection, belong to medical supplies.

Background technology

At present, both at home and abroad in order to prevent and reduce the cross infection of disease, many national productions commercial city starts that developmental research is a kind of is with fool proof syringe, entry needle, scalpel, remaining needles etc. consume articles for use, especially its market of safety injector is very big, international and domestic beginning promoted the use of, but due to safety injector complex structure, manufacturing cost is high, so its sale price of market is three to five times of ordinary syringe or higher, simultaneously according to international governance code requirement, must be stored in the bin of regulation with the syringe of sharp weapon after, destroy together, so also increased storage capsule space, improved destruction cost, for solving above deficiency, need further to improve.

For solving above deficiency, the invention provides a kind of Design of Dies simple, production technology is convenient, a kind of device that can suppress entry needle cross infection that production cost is low

Summary of the invention

The object of the present invention is to provide a kind of device that can suppress entry needle cross infection, more particularly on existing injection needles, be designed with a safe lunge-proof device, entry needle needle stand can be mixed the syringe of different size, until injecting liquid drug or molten medicine, blood drawing, after finishing, starting safe lunge-proof device needle point can be locked in safe lunge-proof device, in general place with destroy middle personnel and can not be wounded by stabbing, reduce manufacturing cost, it is crucial enhancing competitiveness.

In order to solve above whole rational overall process, the present invention is achieved through the following technical solutions.

A kind of device that can suppress entry needle cross infection; this entry needle comprises that needle point sleeve, needle point, needle stand, lug, 6: 100 taper holes, weakness, hook platform, location hook, left and right shelves bar, draw-in groove, hook sheet, drag hook, safety guard, safety guard planes form; wherein needle point sleeve and needle point are assembled up separately; other is injection mo(u)lding together; its needle point bonding is assemblied in needle stand head; needle point endoporus communicates with 6: 100 taper holes, and needle point sleeve is assemblied in and on needle stand, plays the effect of protection needle point.

It is characterized in that: a kind of device of entry needle cross infection that can suppress is due to the reason of weakness, turning 180 ° of safety guard hooks hook sheet with plane on hook platform and safety guard plane drag hook when the same plane, and when safety guard overturns to needle point direction, drag hook is separated with hook sheet.

For reducing packing cost, dwindle space and also can to needle point sleeve upset until draw-in groove blocks needle point sleeve, now reduce packaging volume by safety guard when the fractional pack, reduced production cost and better carried out processes, the while has also reduced cost of transportation.

For enhancing productivity and reducing die cost, needle stand injection mo(u)lding separately, fastening being positioned in hook plate hole of needle stand after molding.

The setting of hook sheet and drag hook is worthy of careful study very much, also be a key technology, when drag hook hooks hook sheet, the little head end of safety guard and needle point are in the relative direction, on hook platform, plane and safety guard plane keep in one plane, otherwise, the little head end of safety guard and needle point are same direction, now drag hook is separated with hook sheet, because the two can overlap with separated, what while making mould, relative prior art was connected and locates by the tension force of cranking arm is simple many, on same injection moulding machine, its output can be more than two times, reduced the energy, improved production efficiency, also improved competitiveness simultaneously, the hook sheet drag hook location that present technique is utilized, this is a kind of design principle for separation, also can use other difformity, the two can overlap with separated principle is all within the scope of present technique.

Another form of present technique, hook plate hole is used after can directly matching with syringe.

The specific embodiment

Below in conjunction with concrete drawings and Examples, the invention will be further described;

As shown in Figure 7, if be sterilising prods, first tear fractional pack, by needle stand upper lug 4 and 6:100 taper hole 5, be directly connected on screw syringe or socket syringe, upset safety guard 13 to drag hook 12 hooks hook sheet 11 to be made it plane stability on safety guard plane 14 and hook platform and remains on a horizontal plane, while giving operation, left space, medical worker can not affect operation because safety guard has fixing rocking when injection simultaneously, treat molten medicine, after injection or blood drawing, by safety guard, to needle point direction, turn to location hook 8 and hook hook platform 7, now needle point has entered left and right shelves bar, by left and right shelves bar, be locked in safety guard, for reducing the space of sharp disposable container, pin and syringe can be deposited respectively to processing after separately, in international norm, generally with sharp weapon with non-sharp weapon to deposit with bargain price be different, so separated, reduce Storage and Processing cost,

In order more to reduce die cost and to enhance productivity, the design of present technique can be close-fitting after the independent injection mo(u)lding of needle stand in the hook plate hole on device, and its result of use is identical;

Present technique another way be the size of the spiral external diameter set according to injector head of hook plate hole dimension on device can close-fitting in the above.

The above, it is only preferred embodiment of the present invention, not the present invention is done to any pro forma restriction, although the present invention discloses as above with preferred embodiment, yet not in order to limit the present invention, any those skilled in the art, do not departing within the scope of technical solution of the present invention, when can utilizing the technology contents of above-mentioned announcement to make a little change or being modified to the equivalent embodiment of equivalent variations, in every case be the content that does not depart from technical solution of the present invention, any simple modification of above embodiment being done according to technical spirit of the present invention, equivalent variations and modification, all still belong to the scope of technical solution of the present invention.
