Embodiment Construction
[0016] In order to further illustrate the present invention, the following specific embodiments are given and described in detail in conjunction with the accompanying drawings.
[0017] see figure 1 and figure 2 , is the heater 100 for the syringe provided in the first embodiment of the present invention. The syringe heater 100 includes a body 10 , a heating module 11 and a protection device 12 arranged on the body. The heating module 11 is disposed between the body 10 and the protection device 12 . The protection device 12 is used to protect the heating module 11 .
[0018] It should be further explained here that the injector of the present invention can be an intramuscular injector, a continuous injector and a drip injector. The intramuscular injector has basically the same structure as the continuous injector, which generally includes a syringe and an injection needle communicating with the syringe. A drip syringe generally includes a packaging container or bag for c...

The invention discloses a heater for an injector. The heater comprises a body and a heating module arranged at the body, wherein the heating module comprises a heating component and at least two electrodes which are arranged at intervals and electrically connected with the heating component. The heating component comprises a plurality of carbon nano tubes. The heater for the injector of the invention can directly fix the body thereof on a packing container or a packing bag of injections or on a transfusion tube so as to heat the injections. When current passes through the heating component, the resistance of the heating component is invariable and the voltage is generally invariable, so that the heat generated by the heater is constant, the heating temperature of the injections is constant and the pharmaceutically required technical standard of heating the injections is met. Meanwhile, the heater can be used only with a power source, thereby avoiding frequent exchange and ensuring simple and convenient use.
Description
technical field [0001] The invention relates to a heater, in particular to a heater for syringes. Background technique [0002] In some medical operations, such as outpatient surgery performed in the home, hospital, and laboratory, patient infusion management is very important. In the surgical operations performed in the hospital, there are certain principles and technical standards for maintaining the patient's body temperature, especially at various stages before, during and after the operation, the patient's body temperature should be kept at normal physiological body temperature to avoid hypothermia and various Various complications, such as delayed recovery from anesthesia, increased oxygen demand, hypoxemia caused by muscle twitching, etc. Considering the above factors, some medical procedures usually heat the intravenous fluid in order to maintain the temperature of the injection at the patient's reasonable physiological temperature. [0003] In most cases at presen...
