Abstract
The utility model relates to a dropping-funnel and filter integrated precise-filtering transfusion device, which belongs to the medical appliance for the clinical vein transfusion, and comprises a dropping funnel with the upper and the lower ends being provided with a liquid inlet and a liquid outlet, and is characterized in that a hollow cylindrical filter body with the upper end belong closed which is integrated with the dropping funnel is vertically arranged at the liquid outlet of the dropping funnel, at least one liquid medicine through hole which is communicated with the dropping funnelis arranged on the cylindrical filter body in the radial direction, and a micro-porous filtering film is wrapped on the outer surface of the cylindrical filter body. By adopting the above structure, the transfusion device has the advantages that the structure is simple, the formation of the air plug of the transfusion device during the transfusion process can be thoroughly solved, and the embolization of the patient during the transfusion process can be avoided so as to eliminate the safety potential danger for the human body caused by the transfusion.
Description
Technical field
This utility model belongs to the medical apparatus and instruments of clinical medical vein transfusion, is specifically related to a kind of dropping funnel, the incorporate precision filter infusion set of filter.
Background technology
Transfusion is to splash into human body large bolus injection medicinal liquid by vein, makes liquid medicine injection directly enter the blood circulation of human body, is medical institutions' one of rescue means commonly used in medical procedure.Disposable use precision filter infusion set is a kind of common new type medical equipment, and its effect is the particulate matter in clinical transfusion and the filtering medicinal liquid.Typical precision filter infusion set is made of parts such as horse Venturi tube, bottle plug puncture unit, dropping funnel, flow regulator, liquid medicine filter, venipuncture needles.Existing precision filter infusion set is in medical personnel's use, must carry out artificial liquid storage at the dropping funnel place when finding mainly to have had use, in case forget liquid storage, gas flows down with medicinal liquid easily, enter in the liquid medicine filter then, form vent plug, stop up liquid medicine filter, and in infusion process, drop also may produce bubble entering dropping funnel, when bubble increased gradually, bubble entered human body with medicinal liquid easily, formed thromboembolism, life security hidden danger when causing transfusion to the patient, prior art products must be provided with a steam vent in order to solve similar problem on precision filter infusion set, to discharge intrasystem gas, and steam vent manufacture with use in break easily, the fault of leakage, therefore, demand urgently prior art is improved, with thorough above-mentioned deficiency of the prior art.
The utility model content
The purpose of this utility model is to solve above-mentioned deficiency of the prior art, prior art is improved, provide a kind of simple in structure, thoroughly solved the formation of transfusion device vent plug in the infusion process, and avoid in infusion process, causing thromboembolism to need transfusion patient, the precision filter infusion set of the personal safety hidden danger that eliminating infuses causes.
For achieving the above object, this utility model is achieved through the following technical solutions:
Be a kind of dropping funnel, the incorporate precision filter infusion set of filter, comprise that upper/lower terminal is processed with the dropping funnel of liquid inlet and outlet, the present technique main points are that the liquid outlet position uprightly is provided with one with it in the dropping funnel, the hollow columnar filter body of upper end closed, radially be processed with at least 1 liquid through-hole that connects with dropping funnel on this column filter body, and the outer surface of central column filter body coats microporous filter membrane.
Liquid through-hole Equal round on the described column filter body and being equally spaced successively from top to bottom, described liquid through-hole diameter is 0.1～3 millimeter.
Because medicinal liquid has certain surface tension, when medicinal liquid enters dropping funnel, can not see through the microporous filter membrane of liquid through-hole and liquid through-hole outside immediately, but in the dropping funnel inner accumulated, so liquid level constantly raises in the dropping funnel.When liquid level in the dropping funnel surpasses the filter body upper end, the inside and outside pressure balance of medical filtration body is broken, pressure differential makes medicinal liquid see through microporous filter membrane and liquid through-hole flows down along liquid outlet, and the liquid level of this moment does not descend, realized automatic control of liquid level, so just can thoroughly eliminate bubble at the dropping funnel position, also just eliminated the phenomenon of the descending obstruction liquid medicine filter of bubble, the bubble that has also solved prior art products enters human body with medicinal liquid easily, form thromboembolism, the life security hidden danger when causing transfusion to the patient.Because the liquid level in the dropping funnel can be controlled automatically, therefore place dropping funnel inside to reduce the setting of the steam vent of liquid medicine filter the medical filtration body, also eliminated the contaminated medicinal liquid potential safety hazard of the medicinal liquid that causes because of steam vent.Have simple in structurely, thoroughly solved the formation of transfusion device vent plug in the infusion process, and avoid in infusion process, causing thromboembolism, eliminate the advantage of the personal safety hidden danger that transfusion causes to need transfusion patient.
Description of drawings
Below in conjunction with accompanying drawing this utility model is described in further detail:
Fig. 1: this utility model embodiment 1 structural representation.
The specific embodiment
As shown in Figure 1, this dropping funnel, the incorporate precision filter infusion set of filter, comprise that upper/lower terminal is processed with the dropping funnel 2 of liquid inlet and outlet 1,7, the present technique main points are that liquid outlet 7 positions uprightly are provided with one with it in the dropping funnel 2, the hollow columnar filter body 4 of upper end closed, radially be processed with at least 1 liquid through-hole 6 that connects with dropping funnel 2 on this column filter body 4, and the outer surface of central column filter body 4 coats microporous filter membrane 5.
Liquid through-hole 6 Equal rounds on the described column filter body 4 and being equally spaced successively from top to bottom, described liquid through-hole 6 diameters are 0.1～3 millimeter.
Because medicinal liquid has certain surface tension, when medicinal liquid enters dropping funnel 2, can not see through the microporous filter membrane 5 of liquid through-hole 6 and liquid through-hole 6 outsides immediately, but in dropping funnel 2 inner accumulated, so liquid level 3 constantly raises in the dropping funnel 2.When liquid level in the dropping funnel 23 surpasses filter body 4 upper ends, the 4 inside and outside pressure balances of medical filtration body are broken, pressure differential makes medicinal liquid see through microporous filter membrane 5 and liquid through-hole 6 flows down along liquid outlet 7, and the liquid level 3 of this moment does not descend, realized the automatic control of liquid level 3, so just can thoroughly eliminate bubble at dropping funnel 2 positions, also just eliminated the phenomenon of the descending obstruction liquid medicine filter of bubble, the bubble that has also solved prior art products enters human body with medicinal liquid easily, form thromboembolism, the life security hidden danger when causing transfusion to the patient.In addition,, therefore place dropping funnel inside to reduce the setting of the steam vent of liquid medicine filter the medical filtration body, also eliminated the contaminated medicinal liquid potential safety hazard of the medicinal liquid that causes because of steam vent because the liquid level in the dropping funnel 2 can be controlled automatically.Have simple in structurely, thoroughly solved the formation of transfusion device vent plug in the infusion process, and avoid in infusion process, causing thromboembolism, eliminate the advantage of the personal safety hidden danger that transfusion causes to need transfusion patient.
