Embodiment 1

[0027] Example 1: such as figure 1 Shown: a self-heating infusion device, including a liquid storage box, a partition, and a gas tube; the partition divides the liquid storage box into a left chamber and 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 communicating hole; a port of the air duct is funnel-shaped, the air duct passes through the partition, one end of the funnel-shaped port is located at the bottom of the left chamber, and the other end is located at the right chamber indoor;

[0028] The top of the left chamber is provided with a filling hole, and the filling 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 An infusion hole, wherein a rubber plug is arranged on the infusion hole;

[0029] It also includes a cork puncture, a dropper, a flow rate regulator, a liquid filter, an infu...

Embodiment 2

[0040] Example 2: On the basis of Example 1, the heating material is changed to the following raw materials by weight:

[0041] 300 grams of calcium oxide, 100 grams of magnesium powder, 100 grams of sodium carbonate, 100 grams of sodium bicarbonate.

[0042] Operation method of heating device:

[0043] In the first step, remove the detachable lid on the top of the cylindrical container, and add 100 grams of tap water to it;

[0044] The second step is to close the detachable lid; it will generate heat 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;

[0045] 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; it can reach 36°C in about 5 minutes, and the heat preservation lasts for 1 hour.

Embodiment 3

[0046] Example 3: On the basis of Example 1, the volume of the left chamber is 800 ml, and the volume of the right chamber is 10 ml.

[0047] The heating material is changed to the following raw materials by weight:

[0048] 300 grams of calcium oxide, 100 grams of magnesium powder, 80 grams of sodium carbonate, 80 grams of sodium bicarbonate.

[0049] Operation method of heating device:

[0050] In the first step, remove the detachable lid on the top of the cylindrical container, and add 100 grams of tap water to it;

[0051] The second step is to put on the detachable lid; it will generate heat 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;

[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 33°C in about 2...

Abstract

The invention discloses a self-heating transfusion device. The device comprises a liquid storage box body, a baffle and an air duct, wherein the liquid storage box body is divided into a left cavity and a right cavity through the baffle, the volume of the left cavity is greater than that of the right cavity, and a communication hole is formed in the bottom of the baffle; one port of the air duct is in a funnel shape, the air duct penetrates through the baffle, and one funnel-shaped end is located in the bottom of the left cavity, and the other end is located in the right cavity; the self-heating transfusion device further comprises a bottle stopper puncture device, a drip chamber, a flow velocity adjuster, a liquid medicine filter, a transfusion hose, an intravenous needle and a heating device. According to the self-heating transfusion device provided by the invention, regardless of fast or slow transfusion speed, the liquid medicine can be dripped at constant speed stably, and the liquid medicine can be heated at the low temperature.

Description

Technical field [0001] The present invention relates to the technical field of medical equipment, in particular to a self-heating infusion device. Background technique [0002] The medical infusion bottle is a bottle used for infusion of medically configured liquid in the human body in a patient's infusion fashion. The infusion set is a common disposable medical consumable used for intravenous infusion that has been sterilized and used to establish a channel between the vein and the liquid medicine. Generally, it is composed of venous needle, protective cap, infusion hose, liquid medicine filter, flow rate regulator, drip bucket, cork puncture, air inlet pipe, and air filter connection. Under atmospheric pressure, the liquid in the infusion bottle flows into the drip hopper along the thin infusion hose. When the pressure of the drip hopper water column is greater than the venous pressure, the liquid in the bottle flows into the vein along the hose. Before using the medical staf...
