Abstract

The utility model discloses a disposable infusion device with a medicine-adding device, consists of a medicine-adding device (3) and a disposable infusion device (6). The inside of the medicine-adding device (3) is a cavity. A medicine aspiration syringe needle (2) is arranged on the upper end. A liquid outlet pipe (5) with a sealing film is arranged on the lower end of the medicine-adding device (3). The liquid outlet pipe (5) is inserted in and connected with the upper infusion tube of the disposable infusion device (6) via the medicine aspiration syringe needle (2). The lower part of the disposable infusion device (6) is inserted in and connected with the liquid outlet pipe (5) on the lower end of the medicine-adding device (3) via a connection syringe needle which is arranged on a Murphy's dropper. The utility model is provided with characteristics of convenient operation, lower cost, conforming to sterile technology operation principles, avoiding the air from entering the vein, time and labor saving, etc.

Description

The disposable transfusion device that has drug feeding device

This utility model belongs to medical instruments field, and what relate generally to is a kind of disposable transfusion device that has drug feeding device.

Traditional disposable transfusion device does not all possess chemicals dosing plant, clinical patient to needs timing intravenous injection antibiotic etc, the mode that adopts is that syringe needle and transfusion device are partly separated at present, connect syringe needle with syringe medicine is pushed, perhaps splash into the side opening of syringe from Murphy type burette.These two kinds of drawbacks that adding method thereof brought have: 1, medical workers is big, and consumed time is long; 2, there is little air to enter vein from the syringe needle junction; 3, pollute easily; 4, push away medicine at every turn all need use the higher syringe of a tool cost.

The purpose of this utility model promptly produces thus, proposes the disposable transfusion device that has drug feeding device that a kind of structural design is simple, use is easy to operate.Use this transfusion device when dosing, can avoid the air admission vein, meet the aseptic technique principle, alleviated staff's labor intensity simultaneously.

For achieving the above object, this utility model is achieved through the following technical solutions: it is made of disposable transfusion device and drug feeding device, in the drug feeding device is cavity, its upper end is provided with inhales the medicine syringe needle, the lower end is provided with the drain pipe of band closing membrane, and this drug feeding device is connected in the top transfusion battalion of disposable transfusion device by inhaling the medicine syringe needle; The bottom of disposable transfusion device is by being provided with the socket connection of connection syringe needle on the drain pipe of drug feeding device lower end on the Murphy type burette.

This utility model structural design is simple, cost is cheap, because its drug feeding device utilizes principle of negative pressure to suck medicinal liquid, and be connected as a single entity with disposable infusion and be used, thereby in the whole operation process, avoided the air admission vein, meet the aseptic technique principle, and it is easy and simple to handle, performance is safe and reliable, has alleviated medical workers, uses when regularly injecting antibiotic and other medicine when being applicable to the clinical patients intravenous drip.

This utility model has following accompanying drawing:

Accompanying drawing 1 is this utility model structural representation.

Accompanying drawing 2 is this utility model drug feeding device structural representation.

Accompanying drawing 3 is this utility model transfusion device hypomere structural representation.

In conjunction with the accompanying drawings, it is as follows to provide embodiment of the present utility model:

As shown in Figure 1, present embodiment mainly is made up of drug feeding device 3 and transfusion device 6.In the drug feeding device 3 (as shown in Figure 2) is cavity, and its upper end is provided with inhales medicine syringe needle 2, and the lower end is provided with the drain pipe 5 of band closing membrane 4, for meeting sterile working's principle, all is with sheath 1,7 on suction medicine syringe needle 2 and drain pipe 5.The Murphy type burette of disposable transfusion device 6 (as shown in Figure 3) is provided with and connects syringe needle 8.Drug feeding device 3 is by inhaling the top tube for transfusion socket connection of medicine syringe needle 2 and disposable transfusion device 6, and the bottom of disposable transfusion device 6 is connected as a single entity with drug feeding device 3 by the closing membrane 4 that the connection syringe needle 8 on the Murphy type burette punctures on the drug feeding device 3 lower end drain pipes 5.Present embodiment in use, remove the needle guard of inhaling on the medicine syringe needle 21,, make it to produce in the cavity negative pressure with hands extruding drug feeding device 3, need are added medicinal liquid suck in the drug feeding devices with imbibition syringe needle 2, then this drug feeding device 3 by 2 socket connections of imbibition syringe needle on disposable transfusion device 6 epimere tube for transfusions.Remove the sheath 7 on the drain pipe 5, the hypomere of disposable transfusion device 6 is connected as a single entity with drug feeding device 3 by the closing membrane 4 that the connection syringe needle 8 on the Murphy type burette punctures on the drug feeding device 3 lower end drain pipes 5, finishes whole dosing process.

Claims

1, a kind of disposable transfusion device that has drug feeding device, comprise disposable transfusion device (6), it is characterized in that: it also has drug feeding device (3), in this drug feeding device (3) is cavity, the upper end is provided with inhales medicine syringe needle (2), the lower end is provided with the drain pipe (5) of band closing membrane (4), and it is by inhaling medicine syringe needle (2) socket connection on the top tube for transfusion of disposable transfusion device (6); The bottom of described disposable transfusion device (6) is provided with by Murphy type burette and connects syringe needle (8) socket connection on the drain pipe (5) of drug feeding device (3) lower end.
