Description
Technical field
This utility model relates to technical field of medical instruments, particularly a kind of dosing utensil.
Background technology
Transfusion is a kind of Therapeutic Method that is widely used.Before infusing, often need some medicinal liquids of preparation.At present, the preparation of medicated powder and medicament generally adopts syringe to finish.Concrete is operating as: syringe is inserted extract a spot of medicinal liquid in the medicinal liquid bottle; Extract syringe then and insert in the powdered medicine bottle, medicinal liquid is injected powdered medicine bottle; After treating that medicated powder and medicinal liquid dissolve fully, extract mixed liquor again out and inject in the infusion bottle.In the above-mentioned process of making up a prescription,,, operation is required great effort very much so can produce certain draught head when operating because medicine bottle is hermetically-sealed construction.For this reason, have many people to propose various solutions, what have has also applied for patent, venous transfusion drug feeding device that provides as Chinese patent 952275732 or the like.Although these drug feeding devices can be finished the purpose of making up a prescription, and solved problems such as the troublesome operation of the process of making up a prescription and draught head, the equal more complicated of its structure need be provided with special-purpose device, has increased product cost.In addition, because designed device is not disposable use, thus need to disinfect, and might cross infection.
Summary of the invention
The purpose of this utility model is at the existing the problems referred to above of existing drug feeding device, and a kind of simple in structure, rapid operation, free of contamination Medicine adder for injection are provided.
For achieving the above object, this utility model has adopted following technical proposal: this Medicine adder for injection comprises needle holder and the syringe needle that is fixed on the needle holder, liquid-through hole is arranged in the syringe needle, outer socket needle tubing of syringe needle and needle tubing seat, needle tubing is fixed on the needle tubing seat, and certain space is arranged between syringe needle and the needle tubing, needle tubing seat and needle holder are fixed together, the sidepiece of needle tubing seat is provided with blow vent, and the front portion of needle tubing is provided with passage, and syringe needle and needle tubing all adopt metal material to make.
Direct and the supporting use of syringe of this Medicine adder for injection.During use, the needle holder of this Medicine adder for injection is socketed on the syringe, inserts in medicinal liquid bottle or the powdered medicine bottle according to common operation sequence then.In operating process, pass through in the liquid-through hole of medicinal liquid from syringe needle, air is then by circulating in the space between syringe needle and the needle tubing, to keep the air pressure balance inside and outside the medicine bottle.
One deck air filtration film is set in the above-mentioned blow vent.The air filtration film filters the air that enters in the medicine bottle, can avoid objectionable impurities such as air atom to enter.
The outlet of liquid-through hole is positioned at the sidepiece of syringe needle in the above-mentioned syringe needle.Pin hole at common needle tip causes breakage to the medicine bottle rubber closure easily, produces rubber and considers the into the liquid problem of going forward side by side to be worth doing, and this Medicine adder for injection is located at the syringe needle sidepiece with the liquid-through hole outlet of syringe needle, has just avoided the appearance of this phenomenon fully.
Compare with existing drug feeding device, the utlity model has following advantage:
1, this Medicine adder for injection is directly to be socketed in the syringe to use, and its structure is very simple, and the cost of product is lower.
2, using this Medicine adder for injection to make up a prescription in the process, the inside and outside Pneumatic pipe cleaner of medicine bottle is crossed gap between syringe needle and the needle tubing and ventilated and keep balance, and is very laborsaving when therefore operating, and can increase work efficiency.
3, the air filtration film that is provided with in the blow vent place can purify the air that enters medicine bottle, the process safety and sanitation of guaranteeing to make up a prescription.
4, because syringe needle and needle tubing all adopt metal material to make, so have stronger puncture ability.
Description of drawings
Accompanying drawing is the sectional structure chart of the Medicine adder for injection that provides of this utility model.
Among the figure, 1, syringe needle; 10, outlet; 2, needle holder; 3, needle tubing; 30, passage; 4, needle tubing seat; 5, air filtration film; 6, blow vent; 7, liquid-through hole.
The specific embodiment
As shown in the figure, Medicine adder for injection of the present utility model comprises syringe needle 1, needle holder 2, needle tubing 3, needle tubing seat 4 and air filtration film 5.Syringe needle 1 and needle holder 2 are basic identical with common structure, and difference is that the outlet 10 of liquid-through hole 7 in the syringe needle 1 is positioned at the sidepiece of syringe needle 1.Like this, can in syringe needle 1 insertion process, avoid producing the rubber bits, guarantee that patient safety uses.Needle tubing 3 is fixed on the needle tubing seat 4, between needle tubing 3 and the syringe needle 1 certain clearance is arranged, but the front end of needle tubing 3 is conical, and closely cooperates with syringe needle 1.Passage 30 is positioned at the front portion of needle tubing 3.In the present embodiment, it is that material is made that syringe needle 1 and needle tubing 3 all adopt rustless steel, and its external diameter can be done lessly; Simultaneously, the cone-shaped nose of needle tubing 3 reaches and syringe needle 1 close-fitting structure, makes this Medicine adder for injection have stronger puncture ability, and the operation of syringe insertion medicine bottle is more laborsaving.4 of needle holder 2 and needle tubing seats adopt plastics to make, and both bond together by glue.
The sidepiece of needle tubing seat 4 has blow vent 6, is provided with one deck air filtration film 5 in the blow vent 6.In the present embodiment, air filtration film 5 adopts hydrophobic membrane to make.
During the supporting use of this Medicine adder for injection and syringe, at first syringe is inserted in the medicinal liquid bottle and extract medicinal liquid.Medicinal liquid in the medicinal liquid bottle is entered in the injection tube by liquid-through hole 7 by the outlet 10 of syringe needle 1 at this moment, air then from blow vent 6 by the space between air filtration film 5 and syringe needle 1 and the needle tubing 3 after, enter in the medicinal liquid bottle by passage 30, to keep the air pressure unanimity inside and outside the medicinal liquid bottle.After finishing this operation, syringe be inserted in the powdered medicine bottle, in powdered medicine bottle, inject medicinal liquid.At this moment, medicinal liquid is to come out from injection tube, by liquid-through hole 7 and export 10 and laggardly go in the powdered medicine bottle, and air be by passage 30 by the space between syringe needle 1 and the needle tubing 3 after, discharge from blow vent 6, just opposite with the process of drawing liquid.
Preferably the product of this Medicine adder for injection adopts disposable use.Like this, can avoid being polluted or cross infection.
