Abstract
The utility model relates to a disposable infusion filter, it is equipped with upper and lower casing and millipore filtration membrane and purifies the layer, and millipore filtration membrane purifies the layer and presss from both sides between upper and lower casing, and the upper casing still is equipped with the venthole, is fixed with the filtration membrane of hydrophobicity in the venthole. The utility model discloses go up the casing venthole and be equipped with the filtration membrane or the filter stopper of hydrophobicity, the bubble in the liquid medicine can be from then on in time, conveniently discharge, and the liquid medicine can not be excessive. The utility model has simple structure, convenient operation and use, and improves the safety of transfusion.
Description
This utility model relates to a kind of medical apparatus and instruments, specifically a kind of disposable infusion filter.
We know that transfusion, blood exchange transfusion set are the medical apparatus and instruments of using always, and filter is again wherein indispensable vitals.At present, liquid medicine filter generally is made up of upper and lower casing and microporous filter membrane purifying layer, and the microporous filter membrane purifying layer is clipped between the infundibulate upper and lower casing, and medicinal liquid is filtered, purifies.Owing to dosing in the infusion process and other reason, be mingled with bubble through regular meeting in the medicinal liquid, if bubble enters in patient's body, will cause trouble even danger to the patient.Therefore, medical personnel will in time drive the bubble in the medicinal liquid out of, to guarantee transfusion safety.And present liquid medicine filter is not easy to carry out aforesaid operations.
The purpose of this utility model is exactly to provide a kind of simple structure in order to overcome above-mentioned the deficiencies in the prior art, and the disposable infusion filter of bubble in the medicinal liquid can be conveniently removed in operation, easy to use.
For achieving the above object, a kind of disposable infusion filter of this utility model, it is provided with upper and lower casing and microporous filter membrane purifying layer, and the microporous filter membrane purifying layer is clipped between the upper and lower casing, it is characterized in that upper shell is provided with venthole, be fixed with hydrophobic filter membrane in the venthole.
Be provided with venthole in this utility model upper shell, hydrophobic filter membrane wherein is housed, from then on the bubble in the medicinal liquid can make things convenient for discharge, and medicinal liquid can be not excessive.This utility model is simple in structure, and operation, easy to use has improved the safety of infusing.
The utility model will be further described below in conjunction with accompanying drawing:
Fig. 1 is a structural representation of the present utility model.
As can be seen from Figure 1, a kind of disposable infusion filter of this utility model, it is provided with upper shell 1, lower house 2 and microporous filter membrane purifying layer 3.The big opening end of infundibulate upper shell 1, lower house 2 is closely pegged graft, and microporous filter membrane purifying layer 3 is clipped between the upper and lower shell susceptor body, to the medicinal liquid filtration.The inlet of upper shell 1, lower house 2 and liquid outlet are communicated with transfusion catheter respectively.Above-mentioned composition, structure and prior art are basic identical, are not giving unnecessary details.
Characteristics of the present utility model are that upper shell 1 also is provided with venthole 4, and hydrophobic filter membrane 5 is installed in the venthole 4, and it can be directly fixed by the ultrasonic heat blow, also can be fixed by the gland of pressure ring 6 or band micropore.Filter membrane 5 has hydrophobicity, that is to say, it has the performance of permeable watertight.Like this, from then on the bubble in the medicinal liquid can make things convenient for discharge, and medicinal liquid can be not excessive.This utility model filter membrane 5 and pressure ring 6 can also be substituted by a hydrophobic plastics porous filtering plug, that is to say in the venthole 4 directly to install and fix hydrophobic plastics porous filtering plug.
This utility model is simple in structure, and operation, easy to use can be discharged the bubble in the medicinal liquid in time, effectively, has guaranteed the safety of transfusion.
