Abstract
The utility model discloses a pressure device for a disposable infusion device, relating to the technical field of a medical apparatus used for inputting medium into a human body. The utility model is characterized in that the air inlet pipe (3) of the disposable infusion device is provided with a switch (4), one end of the air inlet pipe (3) is communicated with the needle head (1) of the infusion device, and the other end of the air inlet pipe (3) is provided with a port (5) which is matched and connected with the nipple of the infusion device. The utility model has the advantages of reasonable design, simple structure, and convenient operation, can effectively prevent the pollution and the leakage of physic liquor, is good for maintaining aseptic operation, and is good for improving the level of peopleis health.
Description
What this utility model related to medical science imports medium intravital instrument field, relates to a kind of pressue device of disposable transfusion device particularly.
In clinical nursing, pressure transfusion is one of routine operation technology.Its operation generally is to adopt traditional syringe needle in Infusion bottle lid directly inserts its bottle.With syringe gas-pressurized is imported in the bottle.Though this method has convenient feasible advantage, also has following shortcoming: the one, syringe needle punctures Infusion bottle lid, often has the rubber granule to bring in the medicinal liquid, easily causes the pollution of medicinal liquid, is unfavorable for the maintenance of sterile working; The 2nd, Infusion bottle lid is through repeatedly puncture, and the bottle inner liquid medicine is easily from the cut water clock, and contaminated environment also causes the unnecessary waste of medicinal liquid etc. simultaneously.
The purpose of this utility model is to overcome above-mentioned shortcoming, and a kind of pressue device of disposable transfusion device is provided, and it can prevent liquid medicine contamination and water clock effectively, helps the maintenance of sterile working.
Task of the present utility model is to realize by the improvement design to disposable transfusion device.Its major technique feature is to be provided with switch 4 on air inlet pipe 3, and an end of air inlet pipe 3 is connected with infusion needle 1 and communicates, and the other end is provided with the port 5 that matches and be connected with the nipple of syringe.
Its technical characterictic is that air inlet pipe 3, switch 4 reach the port 5 that matches and be connected with syringe nipple, makes with polythene material.
This utility model is because only be provided with switch 4 and be provided with the port 5 that matches and be connected with the nipple of syringe at the other end of air inlet pipe 3 on the air inlet pipe 3 of disposable transfusion device, so it is simple in structure, and with low cost.Because it is reasonable in design, do not need the Infusion bottle lid that punctures again during pressurization simultaneously, do not enter medicinal liquid so the rubber granule can not occur, avoided the pollution to medicinal liquid, bottle mouth position is the water clock medicinal liquid no longer, helps the maintenance of sterile working.Owing to pressurize, there is not any specific (special) requirements in the operation in addition, so it is easy to operate, safe and reliable, have no side effect from the other end of air inlet pipe.
Concrete structure of the present utility model is provided by following embodiment and accompanying drawing thereof.
Fig. 1 is the concrete structural front view of using the pressue device of novel proposition.
Describe details and working condition in detail below in conjunction with Fig. 1 according to the pressue device that the utility model proposes.
This device comprises air inlet pipe 3, and the one end is connected with Disposable syringe needle for transfusion device 1 and communicates, and the other end is provided with the port 5 that matches and be connected with the nipple of syringe, and switch 4 is located on the centre position of air inlet pipe 3, and switch 4 is the slip rearrangeable switch.Tube for transfusion 2 communicates with syringe needle 1, and its lower end connects the syringe (all not drawing among the figure) of the human transfusion syringe needle of using and the usefulness of pressurizeing.During work, pressurize on the normal basis of transfusion, the nipple with syringe is inserted in the other end port 5 of air inlet pipe 3 earlier, be connected firmly, after open and close 4, pressurizeing in the medicinal liquid bottle by air inlet pipe 3 with syringe gets final product, the big I of pressure is specifically grasp as required, pressurizeed and closed, can close switch 4, take off syringe, in the time of need not pressurizeing, open switch 4, but normal infusion.It is easy to operate, safe and reliable, have no side effect.Be the desirable apparatus of nursery work pressure transfusion, be easy to popularize.
Claims (2)
1, a kind of pressue device that contains the disposable transfusion device of tube for transfusion, infusion needle and air inlet pipe, it is characterized in that on air inlet pipe (3), being provided with switch (4), one end of air inlet pipe (3) is connected with infusion needle (1) and communicates, and the other end is provided with the connectivity port (5) of matching with the nipple of syringe.
2,, it is characterized in that air inlet pipe (3), switch (4) reach the port (5) that matches and be connected with syringe nipple, make with polythene material according to the pressue device of the described disposable transfusion device of claim 1.
