Abstract
The utility model relates to a disposable infusion set with exhaust pocket for clinic infusion, comprising a transfusion tube, a transfusion plug, an air inlet pipe, a Murphy's drip, an transfusion switch, a micro filter and an intravenous transfusion needle. Below the transfusion tube, an air exhaust pocket is kept between the Murphy's drip and the transfusion switch. The air exhaust pocket shares the same or similar pipe diameter and length with the Murphy's drip yet is provided with a larger volume than the transfusion tube between itself and the Murphy's drip. Both the front and the rear part of the air exhaust pocket are directly connected with the transfusion tube. With the air exhaust pocket, air in the infusion set is available for be exhausted without any waste of liquid medicine. Moreover, the air exhaust pocket is available for be pressed to increase the pressure for transfusion. The utility model has the advantage of reasonable structure, low cost, convenient operation and safe utilization, which effectively solves the difficulty of conventional infusion set in air exhaust and improves the utilization function of disposable infusion set. The utility model has great value in promotion and application.
Description
Affiliated technical field
This utility model relates to the band Exhaust airbag type disposable transfusion device that a kind of clinical transfusion is used, and is widely used in medical institutions such as large, medium and small hospital and clinic.
Background technology
The use of disposable transfusion device is for the patient who needs intravenously administrable has brought facility.Chang Yong transfusion device is a plastic clinically, and it generally is made up of tube for transfusion, air inlet pipe, murphy dropper kettle, transfuse switch, miniature displacer and venoclysis needle.In clinical use, its advantage is a lot, and effect is remarkable, is subjected to the doctor and patient favorable comment, but still there is certain defective, after the infusion bottle medicinal liquid has descended, sky down can appear, renew a bottle liquid medicine, want relatively difficulty of gas that venting enters tube for transfusion, traditional method for exhausting is: make earlier and rush in a certain amount of medicinal liquid in the murphy dropper kettle, open transfuse switch then, a part of medicinal liquid of draining could be outside the gas outlet pipe in the tube for transfusion.This way is complex operation not only, and can slattern quite a few medicinal liquid, causes the certain economic loss.
Summary of the invention
The purpose of this utility model is intended to improve the above-mentioned defective that transfusion device exists, and properly settles the exhaust problem problem that occurs when changing infusion bottle, and a kind of band Exhaust airbag type disposable transfusion device is provided.
This utility model is by the following technical solutions:
Band Exhaust airbag type disposable transfusion device comprises tube for transfusion, transfusion plug, air inlet pipe, murphy dropper kettle, transfuse switch, miniature displacer and venoclysis needle, at the tube for transfusion hypomere, between murphy dropper kettle and the transfuse switch Exhaust airbag is set, the Exhaust airbag profile is quite like murphy dropper kettle, the dosing inclined tube defaults, the caliber of Exhaust airbag is identical with murphy dropper kettle or close with length, and its front and back ends and tube for transfusion are straight-through to be connected, and volume is then greater than the volume of tube for transfusion between it and the murphy dropper kettle.
The Exhaust airbag front and back ends directly is communicated with tube for transfusion and can be made into one, and Exhaust airbag front end and tube for transfusion are pegged graft, and the rear end is communicated with tube for transfusion makes one.
In clinical use, behind sky under the medicinal liquid in the infusion bottle, because the effect that human vein is pressed, the residual one section fluid column of meeting enters a part of gas above the fluid column in transfusion device, at this moment should make the debris cylinder remain on the Exhaust airbag top.Again after changing the medicinal liquid bottle, at first push murphy dropper kettle, make it be full of medicinal liquid, and then the extruding Exhaust airbag, the gas of murphy dropper kettle medicinal liquid below and residual fluid column top can be entered medicinal liquid bottle liquid level top smoothly.Use Exhaust airbag under the situation of not wasting medicinal liquid, to finish the exhaust process of transfusion device smoothly, and simple to operation.In addition, also can carry out pressure transfusion by the extruding Exhaust airbag.
Band Exhaust airbag type disposable transfusion device is rational in infrastructure, with low cost, easy and simple to handle, safe in utilization, has solved the problem of traditional infusion device aerofluxus difficulty effectively, and the perfect function of use of disposable transfusion device, has clinic popularization and application values.
Description of drawings
Accompanying drawing is a structural representation of the present utility model
The specific embodiment
Introduce embodiment of the present utility model below in conjunction with accompanying drawing.
This band Exhaust airbag type disposable transfusion device is made up of transfusion plug (1), air inlet pipe (2), tube for transfusion (3), murphy dropper kettle (4), Exhaust airbag (5), transfuse switch (6), miniature displacer (7) and venoclysis needle (8).Exhaust airbag (5) is located at tube for transfusion (3) hypomere, be positioned between murphy dropper kettle (4) and the transfuse switch (6), with be advisable about murphy dropper kettle spacing 80cm, its caliber is identical or close with murphy dropper kettle (4) with length, front and back ends and tube for transfusion (3) directly are communicated with to be made one and (Exhaust airbag (5) front end and tube for transfusion (3) is pegged graft, the rear end directly is communicated with tube for transfusion (3) makes one), Exhaust airbag (5) volume should be slightly larger than the volume of tube for transfusion (3) between it and the murphy dropper kettle (4).
