Abstract

The utility model relates to a medical article, in particular to a self-exhaust transfusion device which comprises a bottle cork puncture outfit, a conduit, a dropper, a dropping bucket upper cavity body, a dropping bucket partition device, a dropping bucket lower cavity body, a flow rate regulator, a liquid medicine filter and an intravenous needle. The self-exhaust transfusion device is characterized in that: the dropping bucket upper cavity body and the dropping bucket lower cavity body are divided into two cavity zones by the dropping bucket partition device; under the partition action of the dropping bucket partition device, air bubbles produced due to impact of water flow when liquid is left by the dropper can be effectively reduced; due to the cushioning effect of the dropping bucket partition device, liquid flows from the dropping bucket upper cavity body to the dropping bucket lower cavity body to form bubble-less water flow entering the conduit.

Description

A kind of self-venting transfusion device

Technical field

This utility model relates to a kind of medical supplies, is specially a kind of self-venting transfusion device.

Background technology

At present, general infusion set is in the transfusion beginning, when medicinal liquid entered dropping funnel, liquid was easily discharged the gas in the dropping funnel downwards the formation gas-liquid mixture and is entered in the transfusion catheter, therefore produced bubble, simultaneously, because of the pipe inner wall surface tension effects, very easily form absorption pipe inner wall minute bubbles, be difficult for getting rid of, the bubble that is produced easily causes harm such as aeroembolism as entering in patient's body.So, medical personnel are before transfusion, must be with the emptying as far as possible of bubble in the conduit, artificial get rid of minute bubbles that the bubble process needs to be adsorbed on pipe inner wall and constantly play conduit outer wall with the mode of a brief period of time, the minute bubbles of absorption are floated to the dropping funnel more than the liquid level, but be adsorbed in pipe inner wall in the minute bubbles floating-upward process very easily once more, cause whole artificial eliminating bubble process loaded down with trivial details time-consuming, be unfavorable for promptly infusing and giving emergency treatment to a patient, increase work load to medical personnel simultaneously.

The utility model content

At the problems referred to above, the purpose of this utility model is to provide a kind of can prevent effectively that in infusion process bubble from producing and entering in the transfusion catheter, simple in structure, easy to operate, safe and reliable transfusion device.

For achieving the above object, be achieved through the following technical solutions:

The self-venting transfusion device, comprise bottle plug puncture unit, conduit, dropper, dropping funnel upper cavity, dropping funnel partition apparatus, dropping funnel lower chamber, flow regulator, liquid medicine filter and intravenous needle, it is characterized in that: describedly dropping funnel upper cavity dropping funnel lower chamber is divided into two alveolus by the dropping funnel partition apparatus.

Described dropping funnel partition apparatus is divided into two alveolus with dropping funnel between dropping funnel upper cavity and dropping funnel lower chamber.

Described dropping funnel partition apparatus is provided with fluid passage.

This utility model is because on the basis of traditional infusion device, set up to have to prevent that bubble from producing and prevent that bubble from entering the dropping funnel partition apparatus that has infusion channel in the transfusion catheter.This utility model does not in use change medical personnel's transfusion operation custom fully, does not increase operating procedure, can save the loaded down with trivial details process of artificial aerofluxus bubble; After liquid at first cushions through the dropping funnel partition apparatus when entering dropping funnel, to stay the dropping funnel upper cavity towards the bubble that spatters generation, liquid flows into the dropping funnel lower chamber by the infusion channel of dropping funnel partition apparatus, between dropping funnel lower chamber and conduit, form stationary flow, no bubble is brought in the conduit, exempts the artificial aerofluxus bubble of medical personnel process.

This utility model compared with prior art has following advantage:

1, infusion process can prevent that bubble from producing, and alleviates medical personnel's work load, improves transfusion efficient;

2, product structure simple, safe and reliable, be easy to processing and go into operation, can be widely used in clinical.

Description of drawings

Fig. 1 is an integral installation distribution structure sketch map of the present utility model

The specific embodiment

The utility model will be further described below in conjunction with accompanying drawing.

Novel transfusion device as shown in Figure 1 comprises bottle plug puncture unit 1, conduit 2, dropper 3, dropping funnel upper cavity 4, dropping funnel partition apparatus 5, dropping funnel lower chamber 6, actuator 7, liquid medicine filter 8 and transfusion needle 9.Has fluid passage 51 on the dropping funnel partition apparatus 5.

During use, bottle plug puncture unit 1 is inserted the medicinal liquid bottle, and medicinal liquid enters dropping funnel upper cavity 4 from conduit 2 dropper 3 of flowing through, and the fluid passage 51 from dropping funnel partition apparatus 5 flows into dropping funnel lower chambers 6 again, medicinal liquid can use for transfusion along flow through under conduit 2 continuation actuator 7, liquid medicine filter 8, transfusion needle 9.

If do not set up dropping funnel partition apparatus 5, when medicinal liquid flows into formation water column impact dropping funnel lower chamber 6 by dropper 3, will bring conduit 2 into towards the bubble that spatters and punching press forms.If do not set up fluid passage 51, medicinal liquid can't flow into dropping funnel lower chamber 6 from dropping funnel upper cavity 4.

Those of ordinary skill in the art should be realized that, above embodiment just is used for illustrating this utility model, but not conduct is to qualification of the present utility model, as long as in essence scope of design of the present utility model, all will drop in the claim scope of the present utility model variation or the modification of above embodiment.

Claims

1. self-venting transfusion device, comprise bottle plug puncture unit, conduit, dropping funnel, dropping funnel partition apparatus, dropper, flow regulator, liquid medicine filter and intravenous needle, it is characterized in that: describedly dropping funnel upper cavity and dropping funnel lower chamber are divided into two alveolus by the dropping funnel partition apparatus.

2. as self-venting transfusion device as described in claims 1, it is characterized in that: described dropping funnel partition apparatus is divided into two alveolus with dropping funnel upper cavity and dropping funnel lower chamber, and liquid flows through the dropping funnel partition apparatus by the dropping funnel upper cavity, flows into the dropping funnel lower chamber.
