Description

Simple plasma heating device based on plasma replacement therapy

Technical Field

The utility model relates to a simple and easy plasma heating apparatus based on plasma replacement treatment in the medical instrument field heats plasma when can be used to plasma replacement treatment, also can be applied to medical field such as need quick a large amount of infusions such as surgery, emergency treatment, emergency.

Background

Recently, non-biological artificial liver (NBAL) has been widely used in China for treating severe liver disease and liver failure, and its mechanism is based on the strong regeneration ability of hepatocytes, and it uses an extracorporeal circulation device to remove harmful substances in blood and supplement essential components, to stabilize the internal environment of the body in a short time, to temporarily replace partial functions of the liver, to create conditions for the regeneration of hepatocytes and the recovery of liver functions, or to bridge before liver transplantation. The non-biological artificial liver treatment modes commonly used in clinic at present comprise plasma replacement, plasma replacement combined with bilirubin adsorption, dual plasma molecule adsorption combined with plasma replacement and the like, all of the treatment modes inevitably require that a large amount of healthy human plasma (generally 1000-2000ml fresh frozen plasma needs to be input in 1 hour) is input into a patient in a short time, but the functions of various conventional CRRT machines are different, some old CRRT machines do not have a plasma heating function during plasma replacement, a large amount of plasma input into the patient cannot be heated, most of patients with severe liver diseases or liver failure have body failure, so the plasma generally needs to be heated before plasma treatment clinically, and the patient is prevented from being inappropriate due to too low plasma temperature. For a CRRT machine without a plasma warming function, a clean container is generally taken, hot water (35-39 ℃) with proper temperature is poured into the container, and plasma is put into warm water for water bath heating and then is infused into a patient. However, the method often causes the outer wall of the blood plasma bag to be wetted by water, and the label attached outside the blood bag is deformed or even damaged. Meanwhile, warm water is often present at the blood transfusion bag interface, which easily causes plasma pollution. In addition, when the plasma bag is taken out of the warm water, wiped dry and then input into the body of the patient, the process inevitably causes the heat loss of the plasma, especially when the room temperature is low, the patient still feels cold and uncomfortable, which causes poor treatment experience, and meanwhile, the shivering caused by the over-low temperature of the plasma is not easy to be identified with the shivering caused by blood transfusion allergy, which is not beneficial to the treatment.

Detailed Description

To facilitate understanding and practice of the invention by those of ordinary skill in the art, the following detailed description of the invention is provided in connection with the examples, and it is to be understood that the examples described herein are for purposes of illustration and explanation only and are not intended to limit the invention.

As shown in fig. 1-3, a simple and easy plasma heating apparatus based on plasma replacement treatment, including vertical temperature hot plate 9 of placing, be provided with heating intermediate layer 10 in the temperature hot plate 9, temperature hot plate 9 top is provided with couple hole 1, is provided with water injection hole A and wash port B with heating intermediate layer 10 intercommunication on the temperature hot plate 9, and a side of temperature hot plate 9 is provided with the cell 3 of a plurality of pockets form, and cell 3 bottom is provided with cell trompil 5. The hook hole 1 can be hung on a hook of a CRRT machine, a blood plasma bag is placed in the cell 3, the cell opening 5 is used for exposing a blood transfusion interface of the blood plasma bag, the heated blood plasma bag does not need to be taken out, and the blood plasma bag can be directly connected with a blood transfusion device for transfusion, so that the whole transfusion process is in a heat preservation state.
