Abstract
The invention provides a device capable of locking an injection needle with a safety hood after use. The device comprises the safety hood, a locking boss, a locking plate, a positioning hole step, a positioning hole and an injection needle; a clamping groove is formed in a needle seat of the injection needle; when in assembling, a protecting bush can smoothly pass through the positioning hole in the safety hood, and the clamping groove in the needle seat is tightly assembled in the positioning hole; after the liquid medicine injection is done, the safety hood rotates in the same direction as a point of the needle in order to enable the locking boss to enter the locking plate, the point of the needle is locked through the safety hood, thus puncturing by the point of the needle is avoided, and as a result, the cross infection is reduced. According to the safety device capable of locking the injection needle, a technical die is simple to be manufactured, the production efficiency can be raised, the competitiveness is improved, and wide market prospect is brought.
Description
Technical field
The present invention relates to a kind of entry needle by the device that can be locked by safety guard after using.Suppress cross infection, belonged to medical supplies.
Background technology
At present, international, domestic for reducing the cross infection of disease, for reducing medical worker and patient and medical waste treatment people by pin, Trauma.In research and development, be with fool proof medical device, as disposible safety syringe, knife blade etc.For this reason our company July 4 in 2012 Xiang State Intellectual Property Office declared a kind of device that can suppress entry needle cross infection, application number is 2012102383521, and this device is provided with needle point sleeve, needle point, needle stand, lug, 6:100 taper hole weakness, hook platform, location hook, left and right blend stop, draw-in groove, hook sheet, drag hook, safety guard and safety guard plane.Starting drive after needle point injection, turn to location hook 8 by safety guard to needle point direction and hooks hook platform 7.Now needle point has entered left and right blend stop, by left and right blend stop, is locked in safety guard.This device also exists some deficiency in producing the clinical use of neutralization in enormous quantities, as high in left and right blend stop size viscosity, and mould is offered difficulty and strengthened.The easy wearing and tearing of sheet material and fracture production efficiency in injection moulding process in mould are little, although location hook 8 can hook hook platform 7 in addition, but dial also and be easily reversed from out with hands, after contacting with multidigit clinical worker and user simultaneously, comprise Wuxi City the second director's Su Chunyin of the People's Hospital nursing dept. proposal, all think in order to make product safety and reliability, more can not enough be needed continuity further to improve above by clinical acceptance.
For solving above deficiency, the invention provides that a kind of Mould Machining is simpler and easy, cost is lower, and production efficiency can increase substantially, the device being locked by safety guard after a kind of entry needle that is also not easy the new design that is reversed from is simultaneously used.
Summary of the invention
The object of the present invention is to provide a kind of mould to offer device simple and easy, that cost is low, the more reliable one one kinds of entry needles of safety are locked by safety guard after using.The safety that this device removes after old reduction of mould, locking is higher, and production efficiency also increases simultaneously simultaneously, has more improved the market competitiveness.
In order to solve above whole rational overall process, the present invention is achieved through the following technical solutions.
The device that a kind of entry needle is locked by safety guard after using.This device comprises that safety guard, locking boss, locking plate, locating hole step, locating hole, needle stand, draw-in groove, needle point, sheath form.
It is characterized in that: the outer figure diameter of sheath maximum is less than locating hole.During assembling, sheath can pass through locating hole smoothly.Its locating hole step is stuck in the draw-in groove on needle stand, and this design can improve finished product volume of production greatly.
Another feature be on safety guard, reduced left and right blend stop, reduced die manufacturing cost, maintenance cost, improved the production efficiency in injection moulding simultaneously.

The specific embodiment
Below in conjunction with concrete accompanying drawing, to of the present invention, be described further.
As shown in Fig. 4 Fig. 5, for enhancing productivity.First be that needle point is adhesive on needle stand, then overlap upper jacket.Be made into entry needle.This processing technology prior art energy fully-automatic production.Can in advance the entry needle of different size be left in storehouse.During according to the requiring of user's different size and safety guard instrument automatically assembles, can reach production in enormous quantities, efficiency is high.
This key technology is that the outer figure size of the sheath of entry needle is less than the diameter dimension of the locating hole on safety guard.The smooth locating hole of sheath energy during assembling, the external diameter at the draw-in groove position on its needle stand will match with locating hole.Step by the hole that is positioned after locating hole blocks, and the two is fixed as one.Certainly this structure needle stand and safety guard integrated injection molding are also the protection domains of this patent.Prior art is that needle stand first with after the rear bonding of safety guard assembling needle point overlaps upper jacket.This technique completes on a component devices.Equipment investment is large, speed of production is slow, efficiency is low.
While using as shown in Figure 3, tear fractional pack and be assemblied on syringe, contrary safety guard to entry needle needle point, it is fixing as Fig. 6 that direction upset makes it.After treating injecting liquid drug, safety guard makes to lock boss to the equidirectional upset of needle point and enters locking plate, locking boss is a cone, with cone connecting portion be a small cylinder that is less than cone external diameter, for lock boss can be very convenient by locking plate with strengthen locking plate elasticity, locking plate is at least no less than two, locking plate extends to circle central point simultaneously, as shown in Figure 7, now needle point safety is locked by safety guard, and the safety guard after this technology-locking is difficult for being pushed aside.Outside needle point is also difficult for being exposed on, than prior art safety and reliability, as Fig. 8.
In order to lock the easier locking plate that enters of boss, on locking boss cone, can be designed with open slot, as Fig. 9.
The above, it is only preferred embodiment of the present invention, 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, utilize the technology contents of above-mentioned explanation to make a little change or simple modification, all still belong to the scope of technical solution of the present invention.
