Embodiment 1

[0032] Such as figure 1 Shown: a self-heating infusion device, including a liquid storage box, a partition, an air duct 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 and a right chamber; The volume of the left chamber is greater 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

[0047] 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:

[0048] 300 grams of calcium oxide, 100 grams of magnesium powder, 100 grams of sodium carbonate, and 100 grams of sodium bicarbonate.

[0049] How to operate the heating device:

[0050] 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;

[0051] 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;

[0052] 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 in about 2 minutes; ...

Embodiment 3

[0053] 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.

[0054] Described heating material changes the raw material of following parts by weight into:

[0055] Calcium oxide 300 grams, magnesium powder 100 grams, sodium carbonate 80 grams, sodium bicarbonate 80 grams.

[0056] How to operate the heating device:

[0057] 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;

[0058] 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 63°C in about 2 minutes; it can reach 76°C in about 5 minutes, and the heat preservation lasts for 1 hour;

[0059] 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...

Abstract

The invention discloses a self-heating transfusion device, which comprises a liquid storage box body, a clapboard, an air duct, a liquid level sensor, an air inlet valve, a motor and a controller, wherein the liquid storage box body is divided into a left chamber and a right chamber by the clapboard; the volume of the left chamber is larger than the volume of the right chamber; the bottom of the clapboard is provided with a communication hole; the air duct is of a funnel shape; one end with a bigger opening is positioned on the bottom of the left chamber, and the other end is positioned out of the top of the left chamber; the top of the left chamber is provided with a liquid adding hole; the liquid adding hole is provided with a detachable plug; the top of the right chamber is provided with an air inlet; the bottom of the right chamber is provided with a transfusion hole; the transfusion hole is provided with a rubber plug. The self-heating transfusion device also comprises a bottle stopper puncture outfit, a drip chamber, a flow rate regulator, a medicine liquid filter, a transfusion hose, a scalp vein set and a warming device. Medicine liquid can stably drip at constant speed no matter what transfusion speed is, and the medicine liquid can be warmed at a lower temperature.

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 ...
