Problems solved by technology

[0006] The technical problem to be solved by the present invention: in the initial period of time in the existing infusion set, the liquid medicine is always dripped very quickly, which cannot be dripped at a uniform speed and is likely to bring discomfort to the patient's body; and when the infusion speed is fast, It is also prone to the phenomenon that the liquid medicine cannot be dripped at a uniform speed

Embodiment 1

[0039] Such as figure 1 Shown: an infusion device with a heating function, including a liquid storage box, a partition, an air guide tube 3, a liquid level sensor, an air inlet valve, a motor, and a controller; the partition divides the liquid storage box into a left chamber, a right Chamber; the volume of the left chamber is greater than the volume of the right chamber; the bottom of the partition is provided with a communication hole 4;

[0040] The air guide tube 3 is funnel-shaped, one end with a larger opening is located at the bottom of the left chamber, and the other end is located outside the top of the left chamber; the port of the air guide tube 3 located outside the top of the left chamber is provided with an air inlet valve ; The liquid level sensor is arranged in the middle of the inner surface of the side wall of the right chamber;

[0041] The signal detected by the liquid level sensor 11 is input to the controller, and the controller controls the motor to open...

Embodiment 2

[0048] Embodiment 2: On the basis of Embodiment 1, the controller adopts AT89S51 single-chip microcomputer.

Embodiment 3

[0049] Embodiment 3: On the basis of embodiment 1, the volume of the left chamber is 800 milliliters, and the volume of the right chamber is 10 ml.

[0050] The working principle of the present invention: after adding liquid medicine to the left chamber, the liquid medicine in the right chamber will submerge the liquid level sensor. Since the volume of the right chamber is very small, the liquid level will soon be equal to that of the liquid level sensor in the right chamber. Once the liquid level is lower than the height of the liquid level sensor, the controller controls the intake valve so that the air quickly enters the left chamber through the air duct, the pressure at the bottom of the left chamber will increase, and the liquid in the left chamber will Enter the right chamber through the communication hole, and then the liquid level in the right chamber is equal to the liquid level sensor again, so the liquid level in the right chamber is almost constant all the time, so ...

Abstract

The invention discloses a transfusion device with a warming function, and the transfusion device comprises a liquid storage tank, a baffle, a gas-guide tube, a liquid level sensor, a motor, and a controller; the liquid storage tank is divided into a left chamber and a right chamber by the liquid storage tank; the left chamber is greater than the right chamber in volume; the bottom of the baffle is provided with a communicating hole; the gas-guide tube is in the shape of hopper, one end with the greater opening is arranged at the bottom of the right chamber while the other end thereof is arranged outside the left chamber top; the top of the left chamber is provided with a liquid adding hole on which a detachable plug is arranged; the top of the right chamber is provided with a transfusion hole on which a rubber plug is arranged; the transfusion device further comprises a bottle stopper puncture device, a dropping bucket, a flow regulator, a soup filter, a transfusion hose, a vein needle and a heating apparatus. In the transfusion device, regardless of the quick and slow transfusion speed, the soup can be uniformly and steadily dripped and heated at low temperature.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an infusion device with a warming function. Background technique [0002] The medical infusion bottle is a bottle of liquid that is used for infusion in the human body when the patient is infused. The infusion set is a common disposable medical consumable that is used for intravenous infusion after aseptic treatment to establish a channel between the vein and the liquid medicine. Generally, it is composed of a venous needle, a protective cap, an infusion hose, a liquid medicine filter, a flow rate regulator, a drip funnel, a cork puncturer, an air inlet pipe, and an air filter connection. Under the action of atmospheric pressure, the liquid in the infusion bottle flows into the drip funnel along the thinner infusion hose, and when the water column pressure in the drip funnel is greater than the venous pressure, the liquid in the bottle flows into the vein along the hose....
