The specific embodiment
Below in conjunction with accompanying drawing the technical solution of the utility model is described further, but this utility model is not limited in following embodiment.
As shown in Figure 1, a kind of two sidekick type transfusion devices with screw thread liquid medicine filter comprise two perforators 1, two separatory bags 3, four-way spare 4 and transfusion needles 7, and one of them perforator and a separatory bag just form one group of feed liquor mechanism.Described perforator 1 is connected to the liquid feeding end of separatory bag 3, and transfusion needle 7 communicates with four-way spare, so just forms the simplest two sidekick type transfusion devices.
As shown in Figure 5: described four-way spare comprises supervisor 4.1 and arm 4.5, and arm 4.5 is connected to supervisor 4.1 side, roughly is a Y type.Described supervisor 4.1 upper ends are the first feed tube 4.3 of separatory bag liquid outlet, the lower end is for connecting the drain pipe 4.2 of dropping funnel, described arm 4.5 is provided with the second feed tube 4.4 that connects another separatory bag liquid outlet, and this second feed tube 4.4 (makes progress) in the same way with the first feed tube 4.3 openings and is parallel, so so that whole transfusion device is compacter, convenient operation.
This utility model is for the caliber that operates in the first feed tube 4.3 and drain pipe 4.2 caliber less than supervisor 4.1, and the caliber of the second feed tube 4.4 is less than the caliber of arm 4.5.So just more be convenient to assemble perforator or separatory bag.
As shown in Figure 1: the first above-mentioned switch 2 and second switch 9 mainly are in order to regulate the flow of medicinal liquid, to play simultaneously the effect of switch, therefore can adopting pipe clamp, flow regulator etc. to have the device of regulating fluid flow when actual production and all can.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.Concrete is with four-way spare 4 wherein two ports be connected with two separatory bags 3 respectively by the first flexible pipe 5, two other port of four-way spare 4 is communicated with respectively dropping funnel 10 or dosing part 12; Or dropping funnel upper end (inlet) and dosing part 12 be directly installed on two ports of four-way spare 4.Then the first switch 2 is arranged on the first flexible pipe 5 and between separatory bag 3 and two perforators 1.Transfusion needle 7 is by hose connection to liquid medicine filter, then be connected dropping funnel 10 and second switch 9 on the flexible pipe between liquid medicine filter 6 and the four-way spare 3, and second switch 9 is between liquid medicine filter 6 and dropping funnel 10 again.When operating, carry out dosing according to practical situation for convenient, therefore on separatory bag 3, be provided for again adding medicinal bipass 11, and be stamped the tack rubber cap at this bipass 11.In order conveniently to hang up the separatory bag, this utility model is also set up a link at separatory bag 3.In order to make things convenient for medical personnel to watch at any time the medicinal liquid operating position, can also scale value be set at the bag of separatory bag, so more intuitively judge accurately the operating position of medicinal liquid.This utility model also also is provided with respectively between separatory bag 3 and four-way spare 4, is used for regulating feed liquor amount and the feed liquor speed of medicinal liquid.
Flexible pipe in this utility model all is that the lucifuge material of employing or the composite of PVC material or TPU and PVC consist of, and described liquid medicine filter can adopt common drug liquid filter or precision liquid medicine filter, and these can modulate in actual use.
Shown in Fig. 2,3,4, also liquid medicine filter and infusion needle seat are improved in this utility model, the needle stand of liquid medicine filter 6 and transfusion needle 7 adopts the mode that is threaded, thereby so that being connected between transfusion needle and the liquid medicine filter is more solid and reliable.Its concrete structure is shown in Fig. 2,3,4, this utility model changes liquid medicine filter 6 into and being threaded with the connected mode of transfusion between the needle stand, the cone joint periphery wall that concrete is at the lower house 6:100 place of liquid medicine filter 6 arranges connecting thread 13, internal chamber wall at transfusion needle stand 7 is arranged to and the corresponding screw-like of connecting thread, like this with regard to so that liquid medicine filter changes into connected mode between the transfusion needle is threaded.Therefore without leaking, so just solved that transfusion needle and liquid medicine filter cooperation place get loose, the phenomenon of leakage after cooperating firmly, thereby avoided the inconvenience that brings to patient and medical personnel.During concrete assembling, be by rotation transfusion needle stand liquid medicine filter to be cooperated closely with the needle stand of infusing, until rotate motionless till.
A perforator in this utility model, first switch and a separatory bag just form one group of feed liquor mechanism, in needs of production, can increase according to actual needs the quantity of feed liquor mechanism in right amount, get final product thereby accordingly four-way spare is changed to many logical parts.
This utility model is not limited in above-mentioned embodiment, replace or simple increase and decrease therefore those skilled in the art can be equal to according to technique scheme, and the technical scheme that can not derive through creative work all should belong within the technical scope of the present utility model.
