An infusion solution warming device and a method for heating the infusion solution

Abstract

The invention provides a device and method for heating infusion liquid which is used for a patient. The device comprises a heater which is arranged on an infusion tube and is suitable for being arranged on the end of the infusion tube, close to an infusion needle head; the heater comprises a strip-shaped heating element composed of carbon fibers; the carbon fiber heating element can be wound and coated between the lower part of a drop speed clamp and the infusion needle head; the heater is suitable for being arranged on the end of the infusion tube, close to the infusion needle head to ensure that the flow route of the heated liquid in the process that the heated liquid is transmitted to the human body vein from the infusion tube is shortened, the too-long flow time of the liquid in the infusion tube is avoided, and the heat loss of the heated liquid caused by affect from unconnected environment temperature is reduced, so that the heater is suitable for being arranged on the end close to the vein of the patient; and in a service process, the normal infusion process cannot be affected because the device is light in weight.

Description

Technical field [0001] The present invention relates to the technical field of medical equipment, and in particular to a device and method for heating infusion liquid for patient use. Background technique [0002] At present, intravenous infusion is often used to treat diseases, and it is called differently in different places, such as infusion, sling, sling, and drip. In short, intravenous infusion has been widely accepted by doctors and patients. Nowadays, hospitals generally store liquid medicine in warehouses without heating equipment. This creates a large temperature difference between the human body and the liquid medicine. During the infusion process, due to the low temperature of the drug solution, the patient's vasospasm, chills, pain, and chills are often caused. This is called an infusion reaction. In the spring, autumn and winter seasons, children and the infirm have more intense performance. Because of the infusion reaction, the old disease does not get rid of the...

Problems solved by technology

However, PTC components are prone to aging, poor insulation and safety

In addition, it is very important that PTC is a kind of ceramic material. The PTC heating plate has high hardness, high density and weight, and is not flexible enough. Therefore, the infusion warmer made of PTC heating body can only be installed on the upper part of the infusion tube. Or the middle section, it is not suitable to be set close to the patient's vein

The infusion tube near the patient's vein often has a large deformation and bending radius, and the combination stability of the needle tube and the vein cannot bear too much weight, so it is not suitable to install an infusion warmer made of a PTC heating body.

But, the medicinal liquid heated by the infusion warmer reaches the needle through the infusion tube and enters the vein. If the infusion tube between the heater and the needle is too long or the ambient temperature is too low, the medicinal liquid passes through the existing heating system. When the thermostat reaches the needle, the temperature of the liquid medicine will be lower than the set temperature, and the temperature of the liquid entering the human body cannot be accurately controlled.

Moreover, it also has certain restrictions on the operation when the patient is intravenously injected with liquid, which brings certain inconvenience to the nursing staff.

[0005] Scientists have done a lot of research and improved the existing technology for the above shortcomings, such as a kind of infusion warmer disclosed in Chinese patent document 200810140258.6, which is provided with a core, a heating tank, a fixed frame, and a built-in There are semiconductor heating sheets, which use the heating method of semiconductor heating to heat the liquid through the heating tank. However, the semiconductor device has poor control over the current, has a short service life, and has poor insulation and safety.
