Description

Blood bag warming device

The present invention relates to a warming device, and more particularly to a heating device for heating a blood bag.

In the medical process where blood transfusion is urgently needed, since the blood needs to flow smoothly between 20 and 37 degrees Celsius, the refrigerated blood bag taken out from the blood bank needs to be heated to be transported to the human body.

Generally, the contents stored in the blood bag may be blood, plasma, serum, or platelets. However, the blood bag is warmed in a conventional manner to place the cryopreserved blood bag in a container containing warm water. The blood bag exchanges heat with warm water to gradually heat up to the temperature of contact with the human body.

Because the traditional blood bag heating method is only a pre-heating action before blood transfusion, the blood bag is not continuously heated and maintained in a temperature range during the blood transfusion process, and the blood transfusion process is not rapidly completed. If the blood transfusion is carried out in a low temperature environment, such as the operating room, the blood temperature in the blood bag will gradually decrease with time. If the temperature of the blood input into the human body is lower than the temperature of the human body, It will make the blood donor feel strange and cold. Therefore, in the process of blood transfusion, how to control the time of blood transfusion and maintain the temperature of blood is very important.

Therefore, the purpose of the present invention is to provide a blood bag warming device which is portable and can be warmed to a suitable temperature before being transported into the human body.

Therefore, the novel blood bag warming device comprises a casing unit, a heating unit, and a temperature control unit.

The housing unit includes a first housing and a second housing that are releasably and relatively disposed together.

The heating unit covers the inner casing surface of the first casing and the second casing, and generates heat when power is supplied.

The temperature control unit cooperates with an external power supply to form a pair of power supply circuits for supplying power to the heating unit, and performs temperature detection on the heating unit and controls the temperature of the heating unit to a suitable temperature.

The first and second housings cooperate with the heating unit to form an accommodating space for warming up to the appropriate temperature, and the accommodating space is provided for the blood bag.

Preferably, the heating unit comprises a heat-dissipating layer adjacent to the inner casing surface, a coating layer away from the inner casing surfaces, and a sandwiching between the heat-dissipating layer and the cladding layer and supplying electricity A heating layer that generates heat.

Preferably, the heating layer is composed of a carbon fiber heating cloth. The thermal insulation layer is composed of one of an insulating foam and a vacuum insulation layer.

Preferably, the external power source is one of a battery pack and an AC mains.

Preferably, the temperature control unit is electrically connected to an external power source by a universal serial bus bar module. The blood bag warming device further comprises a detachable A composite battery box rectifier device disposed on the housing unit and electrically connectable to the external power source. The composite battery box rectifier device is electrically connected to the temperature control unit by the universal serial bus bar module. The composite battery box rectifier device, the temperature control unit cooperates with the external power source to supply power to the heating unit.

Preferably, the blood bag warming device further comprises a hanging piece. The hanging member can be fixed to one of the composite battery box rectifier device and the housing unit.

Preferably, the housing unit further includes a hook member disposed on the inner casing surface of the first casing and partially exposed to the heating unit. The hook member can be used to limit the blood bag.

Preferably, the temperature control unit comprises a heating indicator lamp disposed outside the housing unit, and the heating indicator lamp is illuminated when the heating layer is in a heating state.

Preferably, the first housing is coupled to the second housing portion. A through hole is formed at a joint between the first housing and the second housing portion, and the through hole is provided for the delivery tube of the blood bag.

The effect of the present invention is that the housing unit and the heating unit cooperate to form an accommodating space capable of warming up to the appropriate temperature, and the blood bag is disposed in the accommodating space for heating to the appropriate The temperature, in the blood transfusion process, can be maintained at the appropriate temperature throughout the blood.
