Abstract
The utility model provides a disposable precise filtering bag type infusion apparatus provided with a three-way valve. The disposable precise filtering bag type infusion apparatus comprises a puncture outfit, a liquid dispensing bag, the three-way valve, a precise liquid medicine filter and an infusion needle. The puncture outfit is connected at the liquid inlet end of the liquid dispensing bag, the three-way valve is connected with the liquid outlet end of the liquid dispensing bag through a first hose, the liquid outlet end of the three-way valve is communicated with the infusion needle, and the precise liquid medicine filter is connected between the three-way valve and the infusion needle. The filter precision of the precise liquid medicine filter is less than or equal to 5mum, thereby greatly improving the filter precision of the infusion apparatus, decreasing the diameter of particulates in liquid medicine and enabling patient health to be further ensured. An original three-way part or a three-fork part is replaced by the three-way valve, so that when a fault occurs and the liquid medicine is required to be prevented from entering, the infusion apparatus can be closed only by directly operating the three-way valve, is quick and convenient to operate and remarkably reduces accident risk.

Background technology
Disposable two pair bag transfusion devices of inserting have become at present the transfusion device of very general use clinically; This type transfusion device mainly overcomes original transfusion device can not thoroughly be separated two kinds of different medicinal liquids; Medicinal liquid is prone to take place drug reaction, medical worker's the big deficiency of the workload of changing dressings.This type transfusion device mainly is made up of perforator, flow regulator, separatory bag, plain filter and transfusion needle.Like Chinese utility model patent number is 20072000241.7 patent, just discloses a kind of two transfusion device of inserting two bags, not high but the deficiency of this type transfusion device is a filtering accuracy, can have influence on patient's health.As the patient who runs into is when being child; Because child's blood vessel is thinner; Adopt this type of transfusion device, then have big microgranule (general filter can only filter the above microgranule of 20um) and get in the medicinal liquid, so then cause child's blood vessel blockage easily; Cause certain negative effect, thereby have influence on the healthy of normal patient.Moreover in the existing transfusion device; Between separatory bag and dropping funnel, adopt tee T or trident to be connected, if in case when error taking place to stop medicinal liquid to be imported at once, need regulate to flow regulator; Like this operating time for a long time relatively long quick inadequately, thereby have influence on patient.Therefore need improve the filtering accuracy of existing two slotting single bag of transfusion devices, thereby patient's health is protected medicinal liquid.
The utility model content
The purpose of this utility model is exactly in order to overcome the existing two not high deficiencies of filtering accuracy of inserting single bag of transfusion devices, and a kind of simple in structure, disposable use secondary filter bag transfusion system with three-way valve that filtering accuracy is high is provided.
The technical scheme that this utility model is adopted to achieve these goals is following: a kind of disposable use secondary filter bag transfusion system with three-way valve; It is characterized in that: comprise perforator, separatory bag, three-way valve, precision liquid medicine filter and transfusion needle; Said perforator is connected the liquid feeding end of separatory bag; Wherein three-way valve is connected with the liquid outlet of separatory bag through first flexible pipe, and the liquid outlet of three-way valve is communicated with transfusion needle, and said precision liquid medicine filter is connected between three-way valve and the transfusion needle.
According to the disposable use secondary filter bag transfusion system described in this utility model with three-way valve; It is characterized in that also comprising being used to control first switch that gets into separatory bag medicinal liquid flow that first switch is arranged on first flexible pipe and between separatory bag and perforator.
The disposable use secondary filter bag transfusion system with three-way valve according to described in this utility model is characterized in that also comprising second switch, and between three-way valve and precision liquid medicine filter.
According to the disposable use secondary filter bag transfusion system described in this utility model with three-way valve; It is characterized in that also comprising dropping funnel; This dropping funnel is between three-way valve and second switch, and wherein three-way valve is the inlet that is directly installed on the dropping funnel inlet or passes through hose connection dropping funnel.
According to the disposable use secondary filter bag transfusion system described in this utility model with three-way valve, it is characterized in that also being provided with on the said separatory bag and be used to add medicinal bipass, be stamped the tack rubber cap on this bipass.
Disposable use secondary filter bag transfusion system according to having three-way valve described in this utility model is characterized in that also being connected on the perforator air filter.
This utility model is through being replaced by precision liquid medicine filter with common liquid medicine filter; The filtering accuracy of this type secondary filter bag transfusion system is≤5um; Thereby improved the filtering accuracy of transfusion device greatly; Reduced the diameter of microgranule in the medicinal liquid, made that patient's health is further guaranteed.This utility model also changes original three-way piece or trident into three-way valve, thus when error taking place need to stop medicinal liquid to get into, only need the straightforward manipulation three-way valve, can close, convenient to operation, significantly reduced the risk of accident.
Description of drawings
Fig. 1 is the structural representation of this utility model.
Among the figure: 1-perforator, 2-first switch, 3-separatory bag, 4-three-way valve, 5-first flexible pipe, 6-precision liquid medicine filter, 7-transfusion needle, 8-air filter, 9-second switch, 10-dropping funnel, 11-bipass.
The specific embodiment
Further specify below in conjunction with the technical scheme of accompanying drawing, but this utility model is not limited in following embodiment this utility model.
As shown in Figure 1: disposable use secondary filter bag transfusion system with three-way valve; It comprises perforator 1, first switch 2, separatory bag 3, three-way valve 4, precision liquid medicine filter 6, transfusion needle 7 and second switch 9, therebetween through first flexible pipe 5 and second hose connection being integral.Aforesaid first switch 2 mainly is in order to regulate the flow of medicinal liquid, to play the effect of switch simultaneously, therefore when actual production, can adopting pipe clamp, flow regulator etc. to have the device of regulating fluid flow and all can with second switch 9.Wherein perforator can be divided into bottle plug puncture unit and disk perforator, and wherein bottle plug puncture unit is provided with air filter 8.Be that three-way valve 4 is connected with separatory bag 3 through first flexible pipe 5 during concrete connection; The outlet of three-way valve 4 is communicated with dropping funnel 10; Perhaps three-way valve is directly installed on dropping funnel upper end, is arranged on first switch 2 on first flexible pipe 5 then and between separatory bag 3 and perforator 1.Transfusion needle 7 is through hose connection to precision liquid medicine filter; Then precision liquid medicine filter 6 is connected on the flexible pipe; On the flexible pipe between precision liquid medicine filter 6 and the three-way valve 3, be connected dropping funnel 10 and second switch 9 then again, and second switch 9 is between precision liquid medicine filter 6 and dropping funnel 10.When operation, carry out dosing for ease, therefore on separatory bag 3, be provided for adding medicinal bipass 11 again, and on this bipass 11, be stamped the tack rubber cap according to practical situation.Hang up the separatory bag for ease, this utility model is also set up a link on separatory bag 3.Medical personnel watch the medicinal liquid operating position at any time for ease, can also on the bag of separatory bag, scale value be set, and visual and accurate is judged the operating position of medicinal liquid so more.
