Description

Technical Field

[0001] The utility model belongs to the field of medical supplies, and more specifically relates to a detachable infusion tube heating device. Background Art

[0002] Infusion is also known as drip or hanging water. It is a large dose of injection that is injected into the body by intravenous drip. It is usually packaged in glass or plastic infusion bottles or bags, without preservatives or antibacterial agents. When used, the drip rate is adjusted through the infusion device, and it enters the vein continuously and stably to replenish body fluids, electrolytes or provide nutrients. Common intravenous infusion fluids include normal saline, Ringer's solution, 5% glucose solution, plasma expander, colloid solution, etc. Studies have shown that the optimal temperature of intravenous infusion fluid is 12-30℃, but the temperature of various liquid medicines is often below 15℃ in winter and spring. Some special liquid medicines need to be refrigerated and stored at low temperatures, and the temperature is even lower when used. The infusion of low-temperature liquids will cause patients to have cold arms, numbness, pain, and chills all over the body. The reason is: low-temperature liquid infusion into the vein, especially a large amount of low-temperature liquid entering the body in a short period of time, increases the patient's body heat consumption, which can easily lead to a decrease in the body's stress capacity. The body cannot adapt to this sudden cold stimulation, and then clinical symptoms such as vasoconstriction, limb chills, and whole body tremors appear.

[0003] In order to solve the above problems, some products that can heat the liquid in the infusion tube have appeared in the prior art, but the existing products still have many shortcomings. In order to prevent cross infection, the infusion tube is treated once and for all. The heating device is fixed on the infusion tube and cannot be uninstalled, which will increase medical costs. The device that generates heating through chemical reaction has too complicated operation process. The temperature of the heating device cannot be controlled and monitored, which may cause the liquid medicine to be denatured and cannot be used normally. Utility Model Content

[0004] In view of the deficiencies of the prior art, the utility model provides a detachable infusion tube heating device, which has a simple design and can be disassembled and installed at any time.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a detachable infusion tube heating device, characterized in that it includes a main heating body, an auxiliary heating body, a battery column, and a droplet sensing device, wherein the droplet sensing device is located at the upper ends of the main heating body and the auxiliary heating body, and the fixed ends of the main heating body and the auxiliary heating body are connected by the battery column, and their mutually closed contact surfaces are respectively provided with heating grooves for heating the infusion tube, and a closing element is arranged between the free ends; the surface of the main heating body includes a data display screen, a heating adjustment gear, a power switch, and a closing element; the detachable infusion tube heating device is a cylinder as a whole, and includes a heating groove, a heat conductive layer, an electric heating layer, a heat insulating layer, a temperature sensing chip, a microcontroller, and a display screen circuit from the inside to the outside.

[0006] Furthermore, the closing element comprises a closing buckle and a closing groove, wherein the closing buckle is located at the free end of the main heating body, and the closing groove is located at the free end of the auxiliary heating body; the inner wall of the heating groove comprises uniformly distributed micro-textures; the heat-conducting layer is located behind the heating groove, and is mainly composed of a heat-conducting silicone sheet; the electric heating layer is located behind the heat-conducting layer, and is mainly composed of an electric heating wire; the heat-insulating layer is located behind the electric heating layer, and is mainly composed of mineral wool; a temperature sensing chip is arranged behind the heat-insulating layer of the main heating body, and the outermost layer is a display screen circuit; a microcontroller is arranged behind the heat-insulating layer of the auxiliary heating body; the droplet sensing device comprises an infrared sensing circuit, a buzzer, and a warning red light;

[0007] Further, the microcontroller is equipped with a wireless communication module;

[0008] Compared with the prior art, the beneficial effects of the utility model are: the device is simple in design and can be disassembled and installed at any time, so as to achieve continuous use and reduce the cost of medical equipment; when the liquid in the infusion tube needs to be heated, the electric heating wire starts to heat up when the power switch is turned on, and the heating gear can be adjusted and the temperature can be visualized; medical staff can heat the drug solution without risk according to the characteristics of the drug and the needs of the patient, thereby avoiding drug denaturation and discomfort symptoms in the patient; it is equipped with a droplet sensing device, and when the patient's drug delivery is completed, its infrared sensor does not sense droplets within two minutes, and the sensing information is converted into an electrical signal received by the microprocessor, triggering the buzzer 3 to alarm; it is equipped with a wireless communication module, and medical staff can receive information related to the heater and the buzzer alarm through the mobile phone, so as to perform appropriate medical care.
