Description

Portable infusion instrument

This utility model relates to a kind of medical infusion device, particularly a kind of portable medical pressure transfusion instrument.

At present, the medical infusion device that generally uses is " hanging bottle type " in the world, comprises that developed countries such as American and Britain, method also are so, have prolonged so far with more than 100 years no significant improvement.Existing medical infusion device, the tall and big heaviness of its drip stand moves inconvenience; Transport patient's difficulty of infusing in the open-air and way; Rescue when the patient needs transfusion fast and be difficult to achieve one's goal.With regard to Chinese patent 90223496.X, though overcome above defective, after medicinal liquid is totally lost, easily air is injected human body, cause the critically ill danger of life; This patent can not be left the 220V power supply, equally medical infusion is brought some inconvenience.This utility model has overcome the weak point of existing medical infusion device, adopts Electronic Control, adds certain pressure in the medicinal liquid bottle, makes medicinal liquid input human body, and is provided with alarm device and the medicinal liquid automatic disconnecting device of being totally lost in circuit.

The purpose of this utility model provides a kind of convenient type medical infusion device, overcomes the defective of existing medical infusion.

The purpose of this utility model is achieved in that as shown in Figure 1, with tube for transfusion (9), infusion bottle (7), Non-return air valve (5), air current limiter (4), elastic bag (3) and external hand pressure balloon couple together through certain pipeline, hand pressure balloon passes through air inlet (1) by the extruding of staff with air, Non-return air valve (2) is squeezed in the elastic bag (3), gas in the elastic bag (3) is by air current limiter (4), Non-return air valve (5), air filter (6) enters in the infusion bottle (7), makes the bottle inner liquid medicine import human body automatically by air pressure.And be provided with infrared transmitter (10) and infrared remote receiver (11) in the bottom of infusion bottle (7), certain position at tube for transfusion (9) is provided with transfusion pipe clamp (8), is provided with elastic bag voltage limiter (12) in outside a distance of elastic bag (3).When the air pressure that injects in elastic bag (3) when the manual pneumatic capsule reached certain limit, elastic bag (3) made voltage limiter (12) connect immediately, makes air pressure indicator lamp (16) bright through oversampling circuit line (13), represented that then gas is sufficient in the elastic bag (3).When the medicinal liquid in the infusion bottle (7) is lower than infrared transmitter (10) and infrared remote receiver (11), then make alarm lamp (20) bright through oversampling circuit line (13), alarm (21) signal of sounding, if in three minutes medical personnel also do not have stop the transfusion, regulate IC 3(22 when then stagnating) connect transfusion pipe clamp (8) through oversampling circuit line (13), tube for transfusion (9) is blocked, and unlikely air injects human body.

This utility model circuit theory as shown in Figure 2, power supply (14) is the dc source of 6V, when this utility model is started working, on and off switch (15) is connected, then power supply indicator (17) is bright, presses test-run a machine switch (19) this moment, and whether the test alarm device is normal.Behind elastic bag (3) sufficient gas, promptly air pressure limits switch (12) connection, and it is bright that then air pressure limits display lamp (16), and expression can stop inflation.When infusion bottle (7) inner liquid medicine was lower than infrared transmitter (10) and infrared remote receiver (11), alarm lamp (20) was bright at once, and alarm (21) sends chimes of doom.When reporting to the police above behind the certain hour (as three minutes) IC 3(22 when then passing through to stagnate) control, circuit (13) is connected, and the pipe clamp (8) of infusing blocks tube for transfusion (9), unlikely air injection human body.

The utility model has the advantages that: 1, do not need heavy drip stand, only need to place patient's head of a bed and get final product; It is convenient to walk back and forth when 2, the patient infuses; It is easy to carry when 3, road transports the patient; When 4, medicinal liquid is totally lost soon, warning system is arranged, when avoiding infusing air is injected the danger of human body; 5, infected point is little.

Claims (1)

1, a kind of portable infusion instrument, it is characterized in that tube for transfusion (9), infusion bottle (7), single gas are serially connected through certain pipeline to valve (5), air current limiter (4), elastic bag (3) and external hand pressure balloon, be provided with infrared transmitter (10) and infrared remote receiver (11) in the bottom of infusion bottle (7), be provided with transfusion pipe clamp (8) at the certain position place of tube for transfusion (9), at the flexible air bag voltage limiter of the outer setting of elastic bag (3) (12).
