Description

Disposable infusion set with dosing device

The utility model belongs to the field of medical equipment, and mainly relates to a disposable transfusion device with a medicine adding device.

Traditional disposable infusion sets do not have a dosing device. For patients who need regular intravenous injection of antibiotics and other drugs, the current method is to separate the needle from the infusion set, and use a syringe to connect the needle to push the drug in, or Use a syringe to instill through the side hole of the Muffer's dropper. The disadvantages brought by these two dosing methods are as follows: 1. The labor intensity of medical staff is high and the time spent is long; 2. A small amount of air will enter the vein from the needle connection; 3. It is easy to cause pollution; 4. Every time Push medicine all needs to use the higher syringe of a cost.

The purpose of this utility model is thus produced, and a disposable infusion set with a dosing device with simple structural design and convenient operation is proposed. The use of the infusion set can prevent air from entering the vein when adding medicine, conforms to the principle of aseptic operation technology, and reduces the labor intensity of staff.

In order to achieve the above object, the utility model is achieved through the following technical solutions: it is composed of a disposable infusion set and a dosing device, the inside of the dosing device is a cavity, the upper end is provided with a drug-absorbing needle, and the lower end is provided with a closed The liquid outlet tube of the membrane, the dosing device is connected to the upper infusion camp of the disposable infusion set through the drug suction needle; On the lower outlet pipe.

The utility model has simple structural design and low cost. Because the dosing device uses the principle of negative pressure to inhale the medicinal liquid and is used in conjunction with the one-time infusion, it avoids air entering the vein during the entire operation process and meets the It adopts the principle of aseptic technique, and its operation is simple, its performance is safe and reliable, and the labor intensity of medical staff is reduced. It is suitable for the regular injection of antibiotics and other drugs during intravenous drip of clinical patients.

The utility model has following drawings:

Accompanying drawing 1 is the structural representation of the utility model.

Accompanying drawing 2 is the structural representation of the utility model dosing device.

Accompanying drawing 3 is the structural schematic diagram of the lower section of the infusion device of the present invention.

In conjunction with accompanying drawing, provide the embodiment of the present utility model as follows:

As shown in FIG. 1 , the present embodiment mainly consists of a dosing device 3 and an infusion device 6 . The dosing device 3 (as shown in Figure 2) is a cavity, its upper end is provided with a drug-absorbing needle 2, and the lower end is provided with a liquid outlet pipe 5 with a sealing film 4. In order to meet the principle of aseptic operation, the drug-absorbing needle 2 And sheath 1,7 is sheathed on the outlet pipe 5. A connection needle 8 is provided on the Murphy's dropper of the disposable infusion set 6 (as shown in FIG. 3 ). The dosing device 3 is plugged and connected to the upper infusion tube of the disposable infusion set 6 through the drug suction needle 2, and the lower part of the disposable infusion set 6 pierces the lower end of the dosing device 3 through the connecting needle 8 on the Muphi dropper. The closing membrane 4 on the pipe 5 is connected with the dosing device 3 as a whole. When this embodiment is in use, remove the needle sheath 1 on the drug-absorbing needle 2, squeeze the drug doser 3 by hand to generate negative pressure in the cavity, and suck the liquid to be added with the liquid-absorbing needle 2 for drug dosing In the device, the drug feeder 3 is plugged and connected to the upper section of the disposable infusion set 6 through the liquid suction needle 2. Remove the sheath 7 on the liquid outlet pipe 5, and the lower section of the disposable infusion set 6 pierces the sealing film 4 on the liquid outlet pipe 5 at the lower end of the dosing device 3 and the dosing device 3 through the connecting needle 8 on the Murphy dropper. Connect as a whole to complete the whole dosing process.
