Abstract
The utility model discloses an automatic control device for a medical infusion apparatus. Three channels including an air inlet channel, a pressure detection channel and a liquid channel respectively are formed in a bottle stopper puncture device; the pressure detection channel is connected with a pressure sensor; and the air inlet channel, the pressure detection channel and the liquid channel are arranged on the bottle stopper puncture device in sequence from top down. When the automatic control device is used, the bottle stopper puncture device of the conventional infusion apparatus is directly inserted into a rubber plug of the liquid channel of the automatic control device. The automatic control device is connected with an infusion stop device, so that the infusion process can be automatically stopped. The pressure sensor is connected with the infusion stop device and a microcontroller, so that the infusion process is automatically stopped when the liquid level of an infusion bottle falls and the pressure detection channel on the bottle stopper puncture device is contacted with atmosphere.
Description
Technical field
This utility model relates to a kind of pressure controlled automatic stopping infusion device.。
Background technology
In infusion process, need the nurse or accompany the people to accompany in the whole journey and at any time observation, timely close transfusion device behind infusion-completed, stopping infusion at present.Easily cause secondary injury in the body as slightly having carelessness, gas to enter, severe one is in peril of one's life.
This utility model can finely overcome the above problems, and the pressure that pressure transducer detects liquid in the bottle in real time changes, and timely close transfusion device when transfusion finishes is in order to avoid cause secondary injury.
Summary of the invention
This utility model is a kind of pressure controlled automatic stopping infusion device
This utility model is achieved through the following technical solutions
A kind of pressure controlled automatic stopping infusion device, its main technical schemes is: three passages are arranged on the bottle plug puncture unit, be respectively inlet channel, pressure detecting passage and fluid passage.Pressure detecting passage Bonding pressure sensor.The sequence of the inlet channel above the bottle plug puncture unit, fluid passage and stress test passage is respectively, and inlet channel is the highest, the pressure detecting passage secondly, fluid passage is minimum.This utility model is that a kind of pressure controlled automatic stopping infusion device has the transfusion arresting stop, the energy automatic stopping infusion, as reopen the necessary manual reset of transfusion.Pressure transducer, transfusion arresting stop all are connected with microcontroller, and liquid level descends in infusion bottle, when the pressure detecting passage on the bottle plug puncture unit contacts atmosphere, and automatic stopping infusion.

The specific embodiment
A kind of pressure controlled automatic stopping infusion device, can not automatic stopping infusion after transfusion is finished for existing fluid delivery apparatus, the utility model proposes following solution, but be described in detail below with reference to the transfusion device device of accompanying drawing 1 and 2 pairs of a kind of infusion-completed automatic stopping infusions of the present invention of accompanying drawing.
A kind of pressure controlled its structure of automatic stopping infusion device of this utility model comprises following five parts: 1, bottle plug puncture unit, 2, pressure transducer, 3, pipeline, 4, the transfusion arresting stop, 5, microcontroller.Three passages are wherein arranged above the bottle plug puncture unit (1), be respectively 6, inlet channel, 7, the pressure detecting passage, 8, fluid passage.Opening at the close pressure transducer (2) of fluid passage (8) has rubber stopper (9), and the bottle plug puncture unit of transfusion device (10) uses and directly inserts rubber closure (8).
The sequence of three passages above the described bottle plug puncture unit (1) is respectively, and inlet channel is the highest, the pressure detecting passage secondly, fluid passage is minimum.
The workflow of a kind of pressure controlled automatic stopping infusion device of this utility model is:
Owing to the existence of liquid, pressure transducer (2) is measured pressure and the atmospheric deviate of liquid in the bottle by pressure detecting passage (7) during normal infusion.When transfusion was near completion, inlet channel (6) opening exposed liquid level at first, and then pressure detecting passage (7) opening exposes liquid level, and pressure transducer (2) detects atmospheric value, and microcontroller (5) stops transfusion by transfusion arresting stop (4).
Except the described technical characterictic of description, be the known technology of those skilled in the art.
Claims (3)
1. a pressure controlled automatic stopping infusion device is characterized in that: three passages are arranged on the bottle plug puncture unit, be respectively inlet channel, pressure detecting passage and fluid passage, pressure detecting passage Bonding pressure sensor.
2. a kind of pressure controlled automatic stopping infusion device according to claim 1, it is characterized in that: the sequence of the inlet channel on the bottle plug puncture unit, pressure detecting passage and fluid passage is respectively, inlet channel is the highest, the pressure detecting passage secondly, fluid passage is minimum.
3. a kind of pressure controlled automatic stopping infusion device according to claim 1, it is characterized in that: be provided with transfusion arresting stop and microcontroller on the pipeline that described bottle plug puncture unit connects, transfusion arresting stop, pressure transducer are connected with microcontroller.
