Liquid medicament thermostat for blood collecting and transfusion machine

Abstract

The invention discloses a liquid medicament thermostat for a blood collecting and transfusion machine. The liquid medicament thermostat comprises a box body and a box cover, wherein the inner side of the box body is fixedly connected with a heating plate; the heating plate is provided with a heating ring, a heating plate temperature sensor and a liquid medicament bag temperature sensor; the inner side of the box body is provided with a liquid medicament bag hook and a ventilation hose which is communicated with an air pump of the blood collecting and transfusion machine; the inner side of the box cover is provided with a pressure plate which is supported by using a sliding pin rod and is limited by using a positioning ring; the liquid medicament bag temperature sensor is arranged on the pressure plate; an air bag is arranged between the pressure plate and the box cover, and is communicated with the air pump in the blood collecting and transfusion machine; a heating ring power line which is connected with the heating ring is connected with a heating control circuit of the blood collecting and transfusion machine through a power line socket; the end part of a temperature detection cable which corresponds to each temperature sensor is provided with a cable connector; and each cable connector is connected with an automatic temperature control circuit of the blood collecting and transfusion machine through a corresponding connector on a temperature monitor. After the liquid medicament thermostat for the blood collecting and transfusion machine is adopted, the temperature of a liquid medicament replenished in a blood collecting and transfusion process is increased, so that the situations of discomfort and chill of blood donors or patients after the injection of cold liquid medicaments into the veins are prevented.

Description

technical field [0001] The invention relates to a medical device, in particular to a medicine liquid thermostat for a blood collection and transfusion machine. Background technique [0002] At present, although many of the machine-used equipment for plasma collection and blood cell collection have added the function of supplementary input of medicinal liquid, the medicinal liquid cannot be heated, and the infusion of supercooled medicinal liquid may cause discomfort or chills. . Therefore, before use, in order to make blood donors feel comfortable and avoid adverse reactions, the liquid medicine bag can only be placed in an incubator in advance or placed in other heating appliances for pre-heating treatment. It has begun to cool down gradually, so the heat preservation effect is not ideal, and it also increases the workload of the operator. When the demand is large, it is necessary to perform constant temperature preheating treatment one day in advance, which increases the ...

Problems solved by technology

[0002] At present, although many of the machine-used equipment for plasma collection and blood cell collection have added the function of supplementary input of medicinal liquid, the medicinal liquid cannot be heated, and the infusion of supercooled medicinal liquid may cause discomfort or chills.

Therefore, before use, in order to make blood donors feel comfortable and avoid adverse reactions, the liquid medicine bag can only be placed in an incubator in advance or placed in other heating appliances for pre-heating treatment. It has begun to cool down gradually, so the heat preservation effect is not ideal, and it also increases the workload of the operator. When the demand is large, it is necessary to perform constant temperature preheating treatment one day in advance, which increases the number of configurations of constant temperature equipment, and there are also problems in the use process. It is inconvenient to take the medicine solution bag, and due to uncontrollable factors of other heating methods, the heating temperature is too high to cause the risk of destroying blood cells

When there is no constant temperature equipment to preheat the liquid medicine, the only way to reduce the replenishment speed of the liquid medicine is to infuse the colder medicine slowly, which greatly reduces the work efficiency
