Abstract

The utility model relates to a syringe for infusion bottles, which relates to the medical appliances and comprises a medical liquor inlet hole 1, a hand pushing block 2, an air inlet 3 and a guiding pipe connecting opening 4. The medical liquor inlet hole 1 is positioned in the neck reducing place below a conical prong. The separation angle between the direction of the medical liquor inlet hole 1 and the opposite direction of the needle head pointing is an acute angle. The contour line of the part below a tip and above the hand pushing block 2 is the arc line without break points. The syringe can effectively prevent the debris of the bottle stoppers from entering the infusion bottle in the process of puncturing, and can prevent the precipitate in the medical liquor bottle from entering the medical liquor inlet hole 1 in the process of descending. The syringe can reduce the damage to the bottle stopper of the physic liquor bottle and can be pulled out and plugged conveniently.

Description

Syringe for infusion bottle

This utility model relates to the transfusion device of medical instruments field, particularly the transfusion device needle for inserting bottle.

Venous transfusion is the conventional means of clinical application, and transfusion device is apparatus commonly used.Present domestic venous transfusion bottle pin (puncture needle) syringe needle, be open-celled structure on the most advanced and sophisticated wedge face, the syringe needle neck inserts in the medicinal liquid, its wedge kept man of a noblewoman need pass rubber stopper earlier, because bottle pin syringe needle medicinal liquid advances the hole direction and overlaps with the direction of insertion that syringe needle wedge face passes rubber stopper, therefore the rubber stopper chip can be shed to inevitably and flow into human body in the transfusion device in inserting process; Because up, the precipitate in the medicinal liquid also falls into medicinal liquid easily and enters the hole, causes patient's discomfort or serial reaction in medicine bottle in perforate.

The purpose of this utility model is to provide a kind of can prevent that the precipitate in crumb of bottle stopper and the medicinal liquid from entering the transfusion device needle for inserting bottle of transfusion device.

Technical solution of the present utility model is: the transfusion device needle for inserting bottle, comprise that medicinal liquid advances hole, hand push shelves, air intlet, conduit connector, and medicinal liquid enters the hole and is positioned at undergauge place under the taper tip, and the reciprocal angle that medicinal liquid advances hole direction and syringe needle indication is an acute angle.The following hand push shelves of needle point serve as the camber line of no break with the contour line on top.The employing non-toxic plastic is a material, single injection-molded.

According to technique scheme, because medicinal liquid enters the undergauge place that the hole is positioned at syringe needle, so can prevent that crumb of bottle stopper from entering transfusion device; The reciprocal angle that advances hole direction and syringe needle indication because of medicinal liquid is an acute angle, makes that into the hole is towards the bottom of medicinal liquid bottle, and the precipitate in the medicinal liquid in preventing from enters transfusion device; Because of the contour line that inserts the syringe needle part in the medicinal liquid bottle camber line, can prevent the damage of syringe needle, and plug and unplug when being convenient to change the medicinal liquid bottle the medicinal liquid bottle stopper for no break.

Accompanying drawing cuts open sketch map for this utility model office.

According to accompanying drawing, a kind of embodiment of the present utility model is described.The transfusion device needle for inserting bottle comprises that medicinal liquid advances hole 1, hand push shelves 2, air intlet 3, conduit connector 4.Medicinal liquid enters hole 1 and is positioned at undergauge place under the taper tip, and the reciprocal angle that medicinal liquid advances hole 1 direction and syringe needle indication is 45 °, and the following hand push shelves 2 of needle point serve as the camber line of no break with the contour line on top.The maximum gauge of taper tip is slightly less than the spacing between the two hand push shelves 2.The employing non-toxic plastic is a raw material, single injection-molded.

Claims

1, transfusion device needle for inserting bottle comprises that medicinal liquid advances hole 1, hand push shelves 2, air intlet 3, conduit connector 4, it is characterized in that medicinal liquid enters hole 1 and is positioned at undergauge place under the taper tip, and the reciprocal angle that medicinal liquid advances hole 1 direction and syringe needle indication is an acute angle.
