Abstract
The utility model relates to a disposable double-channel transfusion needle head, and belongs to a medical device. The transfusion needle head is composed of a drip hole channel and an air inlet channel. The length of the needle head has two kinds, one kind of the needle head is used for a liquid bottle with a capacity of 500 milliliters, the other kind of the needle head is used for liquid bottle with a capacity of 250 milliliters. The utility model is made of medical hard plastic and flexible plastic. The utility model has the advantages that the manufacture is simple, the cost is low, the pollution of physic liquor is reduced, etc.
Description
This utility model belongs to medical apparatus and instruments.
Present disposable transfusion device is widely used in clinical, except that easy to operate, also has certain problem, because air inlet is lower, air will reach pressure of the inside of a bottle through liquid, can increase the liquid contamination chance like this, particularly family transfusion has more antibacterials with in the air admission liquid.
This utility model purpose: reduce the pollution of medicinal liquid, with original infusion bottle syringe needle air inlet position lengthening, liquid level at the bottom of exceeding bottle, weeper is constant, disposable use.
Summary of the invention of the present utility model is: with the infusion bottle syringe needle lengthening of present clinical practice, liquid level at the bottom of the position of its air inlet is exceeded bottle, the infusion bottle needle length is made two kinds, a kind ofly be applicable to that 500 milliliters of bottles use, be about 16-17 centimetre, a kind ofly be applicable to 250 milliliters of bottle usefulness, be about 12-13 centimetre.The making material of this syringe needle is a medical plastic, makes two-chamber, the nearly bottle mouth position of weeper, liquid level at the bottom of the high bottle outlet of air inlet.
The utlity model has the germ contamination that reduces medicinal liquid, cheap, manufacture advantages such as simple.

This utility model most preferred embodiment:
The material of manufacturing of the present utility model all is a medical plastic.The tube for transfusion syringe needle is a duroplasts, can be divided into two kinds of length of 500 milliliters of bottling liquids and 250 milliliters of uses.In Fig. 2: the needle length of 500 milliliters of liquid bottles (1) is 16-17 centimetre, and air inlet (2) exceeds fluid level (7) 0.5cm, and apart from 2.8cm, handgrip part (6) height is 3cm between weeper (3) and the bottle cap (4).Among Fig. 3: the needle length of 250 milliliters of liquid bottles (1) is 12-13 centimetre, and apart from 2.8cm, air inlet (2) exceeds fluid level (7) 0.5cm between weeper (3) and the bottle cap (4), and handgrip part (6) height is 3cm.
Be marked with the branch of large, trumpet in the packing of product, large size is 500 milliliters of bottle usefulness, and trumpet is 250 milliliters of bottle usefulness, and two kinds all need time spent and below puncture needle joining place to change.
The utlity model has widely hospital clinical and use future, manufacture easyly, reliable for effect, have better economic and social benefit.
