Abstract
The utility model relates to a double-sided filtering precise-filtering transfusion device, which belongs to the medical appliance for clinical vein transfusion, and comprises a liquid medicine filterwith the upper and the lower ends being provided with a liquid inlet and a liquid outlet and with two sides being provided with an air exhaustion port, and is characterized in that a filtering film fixed beam is transversely arranged on the upper section of the liquid medicine filter to correspond to the liquid outlet, a filter film is respectively arranged between two sides of the filtering filmfixed beam and the two sides of the corresponding liquid outlet, and the two filtering films divides the liquid outlet and the inner cavity of the liquid medicine filter into two independent cavities. By adopting the double-sided filtering, the filtering area of the filtering film is increased, but the size of the liquid medicine filter is not increased, so that the filtering area can be increased on the premise that the remained medicine inside the liquid medicine filter is free from being increased, and the residual quantity of the liquid medicine can be reduced by 50 percent, thus providing effective guarantee to the dosage of the medicine during the clinical transfusion and reducing the body and the economic loads of the patient.
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 two-sided filtration precision filter infusion set.
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 novel medical apparatus and instruments, 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.The patient is in infusion treatment, particulate matter in the medicine also enters in the body simultaneously, when this particulate matter reaches a threshold quantity, is easy to induce an illness, serious entail dangers to life has become the problem that the world generally payes attention to the control of particulate matter.Be the control microgranule, people often use membrane filtration technique that the medicinal liquid of transfusion is filtered.Its main method is an increase-liquid medicine filter on traditional disposable infusion set basis, and a microporous filter membrane is arranged in the liquid medicine filter, but the particulate matter in the filtering medicinal liquid reduces the infringement of microgranule to human body.
The precision filter infusion set of prior art is found in actual applications, stop up easily in infusion process, stop up for solving, traditional method is that increasing filter membrane area is solved this problem, but when the filter membrane area strengthens, can cause that drug residue strengthens in the precision liquid medicine filter.Dosage is generally pressed the using dosage of human body weight decision medicine during clinical transfusion, when if the liquid medicine filter medicinal liquid residual quantity of using is excessive, existing market is many about 8～10 milliliters with the medicinal liquid residual quantity of liquid medicine filter, because of underdosage influences therapeutic effect, increase patient economy burden easily.Therefore, demand urgently prior art is improved, to solve the great problem of medicinal liquid residual quantity that prior art exists, to alleviate patient's financial burden.
The utility model content
The purpose of this utility model is to solve above-mentioned deficiency of the prior art, and prior art is improved, and provides a kind of simple in structure, the two-sided filtration precision filter infusion set of medicinal liquid less residue.
For achieving the above object, this utility model is achieved through the following technical solutions:
It is a kind of two-sided filtration precision filter infusion set, comprise that upper/lower terminal is processed with liquid inlet and outlet, both sides have the liquid medicine filter of air vent, the present technique main points are the corresponding liquid outlet of liquid medicine filter epimere position horizontally set filter membrane built-in beam, between the both sides of filter membrane built-in beam and the corresponding with it liquid outlet both sides filter membrane is set all, two filter membranes are divided into two mutual independent cavity with liquid outlet and liquid medicine filter inner chamber.
This utility model adopts two-sided filtration to increase the filter area of filter membrane, but therefore the volume of liquid medicine filter does not increase, can increase filter area under the drug residue prerequisite not increasing in the liquid medicine filter, otherwise, can guarantee under the constant prerequisite of filter area, the medicinal liquid residual quantity is reduced about 50%, and the effectiveness of drug dose provides assurance during for clinical transfusion, reduces patient's body and financial burden.
Description of drawings
Below in conjunction with accompanying drawing this utility model is described in further detail:
Fig. 1: this utility model example structure sketch map.
The specific embodiment
As shown in Figure 1, this two-sided filtration precision filter infusion set, comprise that upper/lower terminal is processed with liquid inlet and outlet 1,6, both sides have the liquid medicine filter 4 of air vent, the present technique main points are the corresponding liquid outlet of liquid medicine filter 4 epimeres position horizontally set filter membrane built-in beam 2, between the both sides of filter membrane built-in beam 2 and corresponding with it liquid outlet 6 both sides filter membrane 3,5, two filter membranes 3,5 are set all liquid outlet 6 and liquid medicine filter 4 inner chambers are divided into two mutual independent cavity.
Installation of the present utility model is same as the prior art.Installing when infusing to the patient, medicinal liquid flows down simultaneously from the both sides of filter membrane 3,5, and under the prerequisite that the volume of transfusion device does not strengthen, its filter area has increased by one times than originally, and its flow velocity also increases greatly.
This utility model adopts two-sided filtration to increase the filter area of filter membrane, but therefore the volume of liquid medicine filter does not increase, can increase filter area under the drug residue prerequisite not increasing in the liquid medicine filter, the also corresponding increase of its flow velocity is even adopt the microporous filter membrane of same apertures also can not produce obstruction.Otherwise, can guarantee under the constant prerequisite of filter area the medicinal liquid residual quantity to be reduced about 50%, the effectiveness of drug dose provides assurance during for clinical transfusion, reduces patient's body and financial burden.
