Embodiment Construction

[0021] The present invention is described in further detail below in conjunction with accompanying drawing:

[0022] To determine the blood transfusion line through the installation of various tube clips, firstly, the line identifier (12) determines whether the line type is correct; 11), open the internal circulation loop (10); after 3 seconds, start heating. After 5 seconds, control the ping-pong safety cut-off valve (8) to stop the internal circulation circuit (10), open the patient pipeline (11), and start continuous blood transfusion. When the bubble monitor (6) detects abnormal bubbles, the ping-pong safety shut-off valve (8) is controlled to stop the patient pipeline (11), the internal circulation circuit (10) is opened, and the bubbles are delivered to the drip pot & filter. After completing the exhaust, control the ping-pong safety cut-off valve (8) to end the internal circulation circuit (10), open the patient pipeline (11), and start to continue blood transfusion. ...

Abstract

The invention relates to a rapid-temperature-controlled transfusion pump. The rapid-temperature-controlled transfusion pump is characterized in that a dripping chamber (1) is connected with an transfusion pump body (2) through an infusion pipe (9.1), the transfusion pump body (2) is connected with a heating inductor (3) through an infusion pipe (9.2), the heating inductor (3) is connected with a gas collecting device (4) through an infusion pipe (9.3), the middle of the infusion pipe (9.3) is provided with a temperature monitoring device (5), the infusion pipe below the gas collecting device (4) is provided with branches which are connected through a ping-pang safe stop valve (8), one branch is connected with an inner circulation loop (10), the other branch is connected with a patient loop (11), a bubble monitoring device (6) is installed between the infusion pipe below the gas collecting device (4) and the inner circulation loop (10), the patient loop (11) is provided with a pressure monitor (7), and a liquid medicine inflow pipe recognizing device (12) and an infrared temperature measuring point (13) are arranged above the dripping chamber (1). By means of the rapid-temperature-controlled transfusion pump, the real-time blood temperature ranging from 0 DEG C to 4 DEG C is raised to the temperature ranging from 36 DEG C and 40 DEG C, and fast infusion with the speed of 1000 ml/min is achieved; by means of a paramagnetic body, it can be ensured that the temperature of a heating body for transfusion does not exceed 42 DEG C, and the safety of blood products is guaranteed, necessary protection is achieved for the life safety of a patient; the rapid-temperature-controlled transfusion pump has the one-key emergency infusion function to meet the first-aid need.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and relates to a medical constant temperature infusion device, in particular to a constant temperature blood transfusion pump. Background technique [0002] Medical equipment belongs to a special industry, and various equipment applied to it require high safety. In addition, there are many situations in the application of blood transfusion: such as super large dose, emergency high-speed infusion, etc. At present, most blood transfusion pumps cannot be used for emergency constant temperature infusion. When the patient is rescued in an emergency, the blood transfusion bag is generally heated first, and then the blood transfusion is manually squeezed or mechanically infused. Only one heating cycle takes more than 10 minutes; and for patients with massive blood loss, the blood loss may reach 200ml per minute, or even close to 1000ml . When the blood is heated urgently with high power, it ma...
