Abstract
The utility model relates to a novel venous infusion puncture needle, comprising a sealed metal puncture needle shank, a needle neck and a needle handle; wherein, the needle shank is provided with a cone-shaped sharp needle point; a hole (an air vent) is arranged on the upper-side of the needle point; the puncture needle is inserted in the needle neck; the needle neck is fixed on the needle handle. The utility model is characterized in that a round hole is arranged on each side of the puncture needle shank, and the two round holes are staggered with each other from top to down and are named as a first liquid inlet and a second liquid inlet. Due to the round holes arranged on both sides of the puncture needle, the utility model has the advantages that the distance between the puncture needle hole on the bottle stopper and the bottle stopper on the inner side of the infusion jar (bag) is shortened for complete infusion of the medical liquid, the accurate medical dose is ensured furthest even if when more expensive medicine is used, and the waste is avoided, and the misoperation of exposed needle shank polluting the infusion apparatus is prevented. The utility model is suitable for the hospitals and clinics which are able to perform venous infusion.
Description
Technical field
This utility model belongs to a kind of medical tool, is a kind of novel venous transfusion puncture needle specifically.
Background technology
Venous transfusion is to utilize the physical principle of fluid pressure that a large amount of sterile solutions and medicine are directly splashed into the venous method, also is most common therapeutic method clinically.Present disposable transfusion device and the adapter that uses clinically, the long 3.6--4.0CM of its puncture needle needle body, the pinhole diameter of puncture needle and exhaust needle is 1.6MM, and the thickness of infusion bottle (bag) bottle stopper commonly used is 0.2--0.3CM, pin hole has 3.0--3.2CM from the distance of infusion bottle (bag) bottle stopper, and therefore can occur: 1. infusion bottle (bag) inner liquid medicine can not all be exported, and has the 4.0--6.0ML medicinal liquid to leave over approximately in every bottle (bag), make dosage inaccurate, and cause liquid waste.2. sometimes (particularly some more valuable medicine) in order to save medicinal liquid, and some medical personnel violates sterile working's principle in order to allow medicinal liquid thoroughly flow out clinically, and the needle body of bottle stopper puncture needle is extracted outside the bottle stopper, causes transfusion device to pollute.3. when transfusion device and adapter puncture needle and exhaust needle enter infusion bottle (bag), stopped up pin hole by the rubber of bottle (bag) plug easily, cause transfusion not smooth.4. when transfusion device and adapter puncture needle and exhaust needle enter infusion bottle (bag) simultaneously, also easily the rubber of infusion bottle (bag) bottle stopper is brought in the infusion bottle (bag), generation bottle (bag) interior foreign body causes patient's dispute thus.5. in the carrying patient way, make in the air admission tube for transfusion, cause acting hurriedly in a messy situation of work owing to the infusion bottle (bag) that moves is uneven.
Summary of the invention
The purpose of this utility model provide a kind of can guarantee to greatest extent dosage accurately, avoid waste, stop the novel venous transfusion puncture needle that the needle body exposes the faulty operation method of polluting transfusion device, to overcome above-mentioned deficiency.
To achieve these goals, this utility model is that taper sharp-pointed the sealing metal puncture needle body, pin neck and needle handle constitute by needle point, wherein on the side of needle point, locate to have pin hole (steam vent), puncture needle embeds in the pin neck, the pin neck is fixed on the needle handle, be characterized in: the left and right sides circular hole of respectively opening straggly is from top to bottom located in the both sides at the puncture needle body, is respectively first liquid inlet and second liquid inlet.
Above-mentioned first liquid inlet and the second liquid inlet branch are taken leave of pin neck 1.0CM and 0.5CM.
The Circularhole diameter of above-mentioned first liquid inlet and second liquid inlet is 0.2-0.3CM.
Because this utility model has circular hole in the both sides of puncture needle, like this, puncture needle can not guarantee that transfusion is unobstructed with the rubber obstruction pin hole of bottle (bag) plug when entering infusion bottle (bag); The rubber of infusion bottle (bag) bottle stopper can not brought in the infusion bottle (bag) yet, reduce bottle (bag) interior production of foreign matters, shorten the distance of bottle stopper puncture pin hole and the inboard bottle stopper of infusion bottle (bag) simultaneously, allow medicinal liquid all export, even when using more valuable medicine, also can guarantee the accurate of dosage to greatest extent, avoid waste, stop the needle body and expose the faulty operation method of polluting transfusion device; Even some infusion bottle (bag) bottle stopper is irregular, its thickness is greater than 0.3CM, and blocks second liquid inlet handhole, and also body also can enter tube for transfusion from first liquid inlet.This utility model also can be avoided in the carrying patient way, owing to the imbalance of infusion bottle makes danger in the air admission tube for transfusion, as long as in the infusion bottle (bag) liquid is arranged, principle according to fluid pressure, liquid will flow into from puncturing hole in the tube for transfusion, thereby guarantee patient's safety, thereby reduce acting hurriedly in a messy situation of nursery work.This utility model is applicable to that all can carry out hospital, the clinic of venous transfusion.
Description of drawings
Fig. 1 is this utility model structural representation.
Among the figure: 1-needle point, the 2-needle body, 3-first liquid inlet handhole, 4-second liquid inlet handhole, 5-pin neck, 6-needle handle.
The specific embodiment
Further specify this utility model below in conjunction with accompanying drawing.
This utility model this utility model is made of for sharp-pointed sealing metal puncture needle, pin neck 5 and the needle handle 6 of taper needle point 1, wherein on the side of needle point 1, locate to have pin hole (steam vent), the left and right sides is straggly from top to bottom respectively opens the circular hole that a diameter is 0.2--0.3CM from pin neck 0.5CM and 1.0CM place in the both sides of the needle body 2, is respectively first liquid inlet 3 and second liquid inlet 4.
This utility model can use as the single intravenous infusion adapter again as the single intravenous infusion usefulness that punctures.
The content that is not described in detail in this description belongs to this area professional and technical personnel's known prior art.
