Abstract

The utility model discloses an indwelling needle with transfusion system fixing device, it includes the vein puncture syringe needle, holds needle handle, tee bend, isolation stopper, extension pipe, hinders blood clamp, malleation joint, positive pressure valve and heparin cap, its characterized in that be in the extension pipe on be equipped with and be used for fixing its transfusion needle of transfusion system and extend the buckle of pressing of pipe, during the infusion will extension pipe do the crooked back card of U type and press in this is pressed the buckle, alright play good fixed action. Compared with the prior art, the method has the following advantages: firstly, the fixing is firm, the operation is simple and convenient, and the workload and time of nurses can be saved; secondly, the comfort and the satisfaction of the patient can be improved; thirdly, the visual aesthetic feeling can be more won in clinical application; fourthly, simple structure, low cost, convenient popularization and use clinically.

Description

Indwelling needle with infusion set fixing device

The technical field is as follows:

the utility model relates to an indwelling needle with a transfusion device fixing device.

Background art:

currently, an indwelling needle is widely used for infusion, but most of the indwelling needles in the prior art only consider their own fixation by searching, for example, ZL201820443612.1, and in the case of an infusion set, after an infusion needle head is smoothly fed into a heparin cap of the indwelling needle, an infusion tube is generally fixed on the skin of the human body by using a medical infusion patch or an infusion tape. Thus, the following drawbacks exist: firstly, the application or the adhesive tape is easy to be torn off under the action of external force, so that the effect is lost, the transfusion needle head slips from the heparin cap of the indwelling needle, the transfusion failure is caused, and the exposed needle head slides out and has potential safety hazard of stabbing human bodies; secondly, the patch is applied for a long time to cover and contact the skin, so that skin discomfort is easily caused, and the comfort of a patient is seriously reduced; thirdly, in order to buffer or avoid the falling off of the infusion needle caused by accidental pulling, the extension conduit of the infusion needle needs to be bent and wound for many times and then adhered and fixed, the operation is troublesome, and the fixing effect is often poor; and fourthly, some patients can be allergic to the medical infusion patch or the adhesive tape.

ZL200620071278.9 discloses an anti-slip infusion set, which prevents the slipping between the needle and the heparin cap of the infusion set by arranging a screw sleeve between the needle and the heparin cap. In this way, the existence of the screw sleeve at the needle end not only prevents the operation, but also influences the handiness of the needle end, thereby having the defect of inconvenient operation. Has no popularization in clinic.

The invention content is as follows:

an object of the utility model is to overcome the aforesaid of prior art not enough and provide one kind and not using the infusion to paste or under the condition of infusion sticky tape, can conveniently fix the transfusion system, reduce its transfusion syringe needle from the slippage rate in the heparin cap, do not influence the needle of keeping somewhere that has transfusion system fixing device of infusion operation again.

The utility model aims at realizing the following technical scheme: an indwelling needle with an infusion apparatus fixing device comprises a venipuncture needle head, a needle holding handle, a tee joint, an isolating plug, an extension catheter, a blood blocking clamp, a positive pressure connector, a positive pressure valve and a heparin cap, and is characterized in that the extension catheter is provided with a pressing buckle for fixing an infusion needle extension catheter of the infusion apparatus. Like this, when the infusion, will the extension pipe U type of infusion needle is crooked, the card is pressed press in the buckle of pressing, just can play good fixed action to prevent to pull etc. exogenic action and lead to the syringe needle to break away from or the slippage in its heparin cap. The indwelling needle with the infusion apparatus fixing device can overcome the defects because a medical infusion patch or an infusion adhesive tape is not used or rarely used, and is convenient to operate, safe and reliable. The above object is achieved.

In a preferred embodiment, the present invention proposes that the pressing buckle is non-slidably disposed on the extension tube and is close to one end of the positive pressure connector. Further, the pressing buckle is a bidirectional buckle, and the two bidirectional buckles can respectively clamp the two U-shaped arms after the extension conduit is bent in a U shape.

Compared with the prior art, the utility model has the following advantages: firstly, the fixing is firm, the operation is simple and convenient, and the workload and time of nurses can be saved; secondly, the comfort and the satisfaction of the patient can be improved; thirdly, the visual aesthetic feeling can be more won in clinical application; fourthly, simple structure, low cost, convenient popularization and use clinically.

Description of the drawings:

the present invention will be described in detail below with reference to the accompanying drawings (examples):

fig. 1 is a schematic structural diagram of the present invention.

The specific implementation mode is as follows:

referring to fig. 1, a specific structure of the present invention is shown for example only. The indwelling needle with the infusion apparatus fixing device comprises a venipuncture needle head 1, a needle holding handle 2, a tee joint 3, an isolating plug 4, an extension catheter 5, a blood blocking clamp 6, a positive pressure joint 7, a positive pressure valve 8 and a heparin cap 9, and is characterized in that the extension catheter 5 is provided with a pressing buckle 10 for fixing an infusion needle extension catheter of the infusion apparatus, and the extension catheter is bent in a U shape and then clamped and pressed in the pressing buckle 10 during infusion, so that a good fixing effect can be achieved. The utility model discloses an additional characteristic lie in press buckle 10 be in extension pipe 5 on be the nonslip setting, and be close to malleation joint 7 one end. Further, the pressing buckle is a bidirectional buckle, and the two bidirectional buckles can respectively clamp the two U-shaped arms after the extension conduit is bent in a U shape.

Claims

1. The utility model provides an indwelling needle with transfusion system fixing device, it includes the vein puncture syringe needle, holds needle handle, tee bend, isolation stopper, extension pipe, hinders blood clamp, malleation joint, positive pressure valve and heparin cap, its characterized in that extension pipe on be equipped with the press buckle that is used for fixing its transfusion needle of transfusion system extension pipe, during the infusion with extension pipe do the crooked back card of U type and press in this press buckle, alright play good fixed action.
