Description

Novopen syringe needle attaching/detaching apparatus

Technical field

The utility model relates to a kind of medical instrument, especially a kind of device that cooperation novopen uses.

Background technique

Diabetes as a kind of frequently-occurring chronic disease, the number of patient be it is very huge, when progression of the disease to certain rank When section, it is necessary to insulin injection is carried out by novopen, to reach daily therapeutic purposes.

And when patient per uses novopen, installation and removal syringe needle is essential two steps, right For the state of an illness is compared with light and little age patient, problem is not especially big, but for being in a bad way, (such as diabetes cause Blind and diabetes cause finger tips tactile bad) and older patient for, just it is relatively difficult, patient is frequent The finger of oneself can be pierced, and in hospital, especially diabetes lesion, nurse's one action amount are exactly to inject five or six ten pancreases Island element often punctures finger in busy work, therefore how effective and safe dismounts syringe needle, is a big problem.

And it is further, insulin needs to shake up before the injection, such as Novolin 30R, novolin 50R, novorapid 30 be short-acting or Semilente Insulin mixes in proportion with intermediate-acting insulins, also known as Mixed insulin；And during Novolin N is Property insulin suspension, main component is isophane insulin.Some ingredients can be with precipitating after this para-insulin is stood Form is brought together, and the purpose shaken up is to mix well ingredient therein, and the insulin component and concentration injected in this way are It is accurate.For example Novolin 30R is made of 30% short-acting insulin and 70% intermediate-acting insulins, if before injection It does not shake up, the ratio of injection may just change, and certainly will influence whether your therapeutic effect in this way, however old age is suffered from For person and the nurse of big workload, shaking up insulin is also a problem.

Summary of the invention

The purpose of this utility model is to provide a kind of simple and reasonable, blind patient can be convenient for, Older patient and Nurse safety dismounts syringe needle, at the same can be convenient and efficient shake up insulin, and convenient for especially recycling the novopen of syringe needle Syringe needle attaching/detaching apparatus.

A kind of in order to achieve the above object, the technical solution of the present invention is: novopen syringe needle attaching/detaching apparatus, including The dismounting pipe matched with external syringe needle box, the end periphery for dismounting pipe have retaining ring, and the inner cavity for dismounting pipe is located at nozzle Internal diameter M is greater than the internal diameter N being located at tube bottom, and the inner wall for dismounting pipe is equipped with rubber convex subgroup.

Also there is outer tube, dismounting pipe is inserted into the inner cavity of outer tube, and the intracavity bottom of outer tube has the first spring, the first bullet One end of spring is fixedly connected with outer pipe bottom, and when in the inner cavity for dismounting pipe insertion outer tube, the other end of the first spring is resisted against Dismount the end of pipe.

The end of the outer tube has internal screw thread connecting tube, and pedestal connects with one end of second spring, second spring it is another One end has screw rod, and by the cooperation of screw rod and internal screw thread connecting tube, outer tube is mounted on the base.

Angle α between the outer wall and dismounting pipe of the retaining ring is 90 ° ~ 120 °.

The bead position of the retaining ring is equipped with pulling buckle.

The pedestal is additionally provided with sucker.

The pedestal includes connect with second spring swivel plate and the fixed plate that connects with sucker, and the surface of fixed plate is provided with Annular groove, annular groove is interior to have ball, and swivel plate passes through the rotation connection of ball realization and fixed plate.

After adopting the above structure, as follows the advantages of the utility model:

The utility model is that the installation and removal of syringe needle are realized using dismounting pipe, when injection, tears the thin of syringe needle box Film, syringe needle box is opening up, it is put into dismounting pipe, since dismounting pipe is up big and down small structure, no matter which kind of model Syringe needle box can be stuck in dismounting pipe inner cavity in, at this point, by novopen extend into dismounting pipe inner cavity in, it will be able to Syringe needle box is touched, novopen can be pressed down on, in this way, syringe needle is with regard to spiral shell while rotating novopen at this time Rotation is mounted on novopen, while extracting novopen, has just taken syringe needle out of, similarly, when injection finishes, needs to remove When syringe needle, so that it may extend into novopen in the inner cavity of dismounting pipe together with syringe needle, syringe needle is just inserted into syringe needle box at this time , novopen is reversely rotated at this time and is extracted, and syringe needle is just removed, and the overall process for dismounting syringe needle is not all needed with hand contact pin Head ensure that safety, while not delay the operating time.

And since dismounting pipe periphery has retaining ring, even syringe needle also can be by when patient holds dismounting pipe Retaining ring is blocked, and patient will not be stabbed, further, since the angle α between the outer wall and dismounting pipe of retaining ring is 90 ° ~ 120 ° (preferably 120 °), thus retaining ring be really be in it is up big and down small funnelform, patient only needs for novopen substantially to extend into In retaining ring, it can be entered in dismounting pipe along retaining ring novopen, accordingly even when being that blind person patient and gerontal patient may be used With convenient practical, and for nurse, such structure greatly accelerates working efficiency, does not have to carefully by syringe needle pair The inner cavity of quasi- dismounting pipe.

And the utility model also has outer tube and a pedestal, dismounting pipe is to be inserted into the inner cavity of outer tube when use, then Outer tube may be mounted on pedestal, and benefit brought by this spline structure is exactly that the utility model can be fixed on platform using sucker On face, it is not easy to roll everywhere, blind person patient can be quickly found out in fixed position, and also facilitate shield in many and diverse hospital environment Scholar takes, and cooperates second spring, and when use can move outer tube, has then moved dismounting pipe, and such novopen does not just have to It is inserted in 90 °, while facilitating insertion, also facilitates observation syringe needle box, meanwhile, insulin needs to shake up before use, After novopen is inserted on the utility model, dismounting pipe can be lifted by pulling buckle, then loosens, passes through the first bullet in this way Spring, dismounting pipe just drive novopen to move up and down and realize shake by the first spring, shake up insulin from up and down direction, And it is further, by stirring rotating disk, outer tube and its internal dismounting pipe rotation are just driven, then novopen also occurs Rotation achievees the purpose that mix insulin.

The utility model can safely and fast dismount syringe needle, while conveniently shake up insulin, meanwhile, when syringe needle is removed Afterwards, dismounting pipe can be taken out by pulling buckle, syringe needle, syringe needle box are all stuck in dismounting pipe and do not expose at this time, directly throw away and tear open Tubulature more renews, and such structure is especially practical in hospital, and syringe needle can be placed reliably, will not stab shield Scholar's hand.
