Embodiment 1

[0032] Such as figure 1 Shown: a self-heating infusion device, including a liquid storage box, a partition, an air guide tube 3, a liquid level sensor, an air intake valve, a motor, and a controller; the partition divides the liquid storage box into a left chamber, Right chamber; the volume of the left chamber is larger than that of the right chamber; the bottom of the partition is provided with a communication hole 4, so that the liquid in the left chamber and the right chamber can communicate;

[0033] 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 outside the top of the left chamber is provided with an air intake valve ; The liquid level sensor is arranged in the middle of the inner surface of the side wall of the right chamber;

[0034] The signal detected by the liquid level sensor 11 is input to the contro...

Embodiment 2

[0046] Embodiment 2: On the basis of embodiment 1, controller adopts AT89S51 single-chip microcomputer, and described heating material changes the raw material of following weight part into:

[0047] 300 grams of quicklime, 80 grams of aluminum powder, 30 grams of anhydrous aluminum chloride, 40 grams of iron powder, and 30 grams of surfactant.

[0048] How to operate the heating device:

[0049] In the first step, remove the removable cover set on the top of the cylindrical container, and add 100 grams of tap water to it;

[0050] The second step is to cover the detachable lid; it will heat up in about 10 seconds, and the temperature inside the cylindrical container can reach 65°C in about 2 minutes; it can reach 75°C in about 5 minutes, and the heat preservation lasts for 1 hour;

[0051] In the third step, since the infusion hose is located in the groove on the surface of the cylindrical container, the temperature of the liquid medicine in the infusion hose can reach 31°C ...

Embodiment 3

[0052] 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.

[0053] Described heating material changes the raw material of following parts by weight into:

[0054] 300 grams of quicklime, 80 grams of aluminum powder, 20 grams of anhydrous aluminum chloride, 30 grams of iron powder, and 20 grams of surfactant.

[0055] How to operate the heating device:

[0056] In the first step, remove the removable cover set on the top of the cylindrical container, and add 100 grams of tap water to it;

[0057] The second step is to cover the detachable lid; it will heat up in about 10 seconds, and the temperature inside the cylindrical container can reach 60°C in about 2 minutes; it can reach 73°C in about 5 minutes, and the heat preservation lasts for 1 hour;

[0058] In the third step, since the infusion hose is located in the groove on the surface of the cylindrical container, the temperature of th...

Abstract

The invention discloses a self-heating infusion device. The self-heating infusion device comprises a liquid storage box, a separating plate, a gas guide pipe, a level sensor, a gas intake valve, a motor and a controller. The separating plate divides the liquid storage box into a left cavity and a right cavity; the volume of the left cavity is larger than that of the right cavity; the bottom of the separating plate is provided with a communicating hole; the gas guide pipe is in the shape of a funnel, the larger opening end of the gas guide pipe is arranged at the bottom of the left cavity and the other end of the gas guide pipe is arranged outside the top of the right cavity; the top of the left cavity is provided with a liquid feeding hole which is provided with a removable plug; the top of the right cavity is provided with a gas inlet hole; the bottom of the right cavity is provided with an infusion hole which is provided with a rubber plug. The self-heating infusion device also comprises a plug puncture unit, a dripping bucket, a velocity adjustor, a liquor filter, an infusion hose, a vein needle and a heating device. According to the self-heating infusion device, liquor can drip stably at a constant speed whatever the velocity, and meanwhile, the liquor can be heated in low-temperature weather.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a self-heating transfusion device. 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. Before ...
