Abstract

The utility model provides a multifunction transfusion device, which improves an exhaust pipe for a transfusion device. The end opening of the exhaust pipe is inserted with an end plug; the external dimension of one end of the end plug is consistent with that of the papilla of a needle tube; the size of an inner hole of the other end of the end plug can be matched with the papilla of the needle tube; a filter screen is arranged in the inner hole of the end plug which is also provided with a cover. Except for the normal exhaust function and filtering function, the utility model can also make the pressurizing transfusion and add medicament in the process of transfusion according to the needs of the patient condition.

Description

Multifunctional transfusion system

This utility model is the improvement to the disposable medical transfusion device.

At present, the disposable transfusion device of Shi Yonging is made by plastic flexible pipe clinically, has a bypass pipe (mouth) to make exhaustor usefulness on it inserts the large needle of medicine bottle, and a filtering bodies is arranged in this exhaustor, is used for impurity in the filtered air.The exhaustor of this structure has aerofluxus and filters dual-use function, but in clinical practice, need add an amount of medicament sometimes in infusion process, and perhaps due to illness feelings need, the transfusion fast of pressurizeing.And used transfusion device just can't satisfy this requirement, have to pressurize or adds medicament with needle tubing, so just causes the pollution of syringe needle to medicinal liquid easily.

The purpose of this utility model is that a kind of multi-functional disposable transfusion device will be provided, and it is increased on the basis with aerofluxus, filtering function again can pressurize easily and the function of dosing, eliminates the pollution of syringe needle.

The purpose of this utility model is to realize like this, port to the transfusion device exhaustor improves, the endoporus size design of exhaustor port is become with the needle tubing nipple and can coincide, insert a plug at the exhaustor port, an end of plug is designed to the same with the needle tubing nipple, round table-like, the other end endoporus size design Cheng Nengyu needle tubing nipple of plug matches, and having lid, the endoporus of plug communicates, and drainage screen is arranged in the endoporus.

This utility model when being necessary, can directly pressurize or dosing by exhaustor owing to the port at the transfusion device exhaustor has inserted plug, has avoided the pollution of syringe needle.

Fig. 1 is the structural representation according to multifunctional transfusion system provided by the utility model;

Fig. 2 is the structural representation according to the exhaustor plug of multifunctional transfusion system provided by the utility model.

Among the figure, the big syringe needle of 1-, 2-exhaustor, 3-filtering bodies, 4-exhaustor port, 5-plug, 6-lid, 7-drainage screen, 8-plug endoporus.

Describe concrete structure of the present utility model in detail below in conjunction with accompanying drawing

This utility model mainly is that the exhaustor to transfusion device improves, and the inner chamber of the port 4 of the bypass exhaustor 2 of the big syringe needle 1 of transfusion device is designed to and can matches with the needle tubing nipple, inserts a plug 5 on port 4.The overall dimensions of plug one end is designed to the same with the needle tubing nipple, and the endoporus 8 of the other end of plug 5 is made and can be matched with the needle tubing nipple, and the endoporus of plug 5 communicates, drainage screen 7 is housed in the endoporus, and plug 5 also has lid 6, before using or when suspending transfusion, the lid lid is tight, to guarantee health.

During normal infusion, only need open the lid 6 on the plug 5, exhaustor 2 just can carry out normal air inlet, and air is through drainage screen 7 and filtering bodies 3 secondary filters, and the air that enters medicine bottle is very clean.When the state of an illness need be carried out pressure transfusion, only need the needle tubing nipple is directly inserted in the plug 5, just can in medicine bottle, calm the anger; When needs add medicament in infusion process, as long as plug 5 is taken, the needle tubing nipple inserts exhaustor port 4, can pass through the exhaustor dosing, and dosing finishes, and pulls up needle tubing, plug is plugged to get final product again.

Transfusion device exhaustor provided by the utility model has aerofluxus, filtration, pressurization and dosing multi-functional, has avoided the pollution of syringe needle to medicinal liquid.

Claims (3)

1. disposable transfusion device, form by big small pinhead, tube for transfusion, exhaustor etc., it is characterized in that, the port of exhaustor inserts plug 5, one end overall dimensions of plug insertion exhaustor is consistent with the needle tubing nipple, the endoporus of the other end of plug can match with the needle tubing nipple, in the plug endoporus drainage screen is housed.

2. transfusion device according to claim 1 is characterized in that, hole dimension and needle tubing nipple match in the said exhaustor port.

3. transfusion device according to claim 1 is characterized in that, has lid on the said plug.
