Heat-preservation device for drug application of otolaryngology department

Abstract

The invention discloses a heat-preservation device for drug application of the otolaryngology department. The heat-preservation device comprises a fan and is characterized in that the fan is fixedly mounted on a drug application cylinder, an electric heater is fixedly mounted on the drug application cylinder, the air inlet of the fan is communicated with the heating cavity of the electric heater through a pipeline, the cylinder body of the drug application cylinder comprises an outer shell and an inner shell, a cavity is formed between the outer shell and the inner shell, the air outlet of thefan is communicated with the cavity through a pipeline, the drug application cylinder is provided with a stirring mechanism, one end of a drug application tube penetrates the lateral wall of the drugapplication cylinder and extends to the bottom of the inner cavity of the drug application cylinder, a temperature sensor is fixedly mounted at the bottom of the lateral wall of the drug applicationcylinder, and a bottom plate is arranged on the lower side of the drug application cylinder. The heat-preservation device has the advantages that heating and heat preservation can be performed on liquid drugs in the drug application cylinder, the effects of the liquid drugs cannot be destroyed, good heat preservation uniformity is achieved, the device can be used as a drug mixing device, and liquid drug precipitation which affects the effects of the liquid drugs can be avoided.

Description

technical field [0001] The invention relates to the technical field of ENT drug delivery devices, in particular to an ENT drug delivery warmer. Background technique [0002] Otolaryngology is the surgical discipline that diagnoses and treats the ear, nose, pharynx, larynx, and related head and neck regions. With the advancement and development of science and technology, various medical disciplines have penetrated and promoted each other, expanding the scope of otolaryngology, ear microsurgery, ear neurosurgery, lateral skull base surgery, audiology and balance science, nasal endoscopic surgery, nasal surgery, etc. The emergence of neurosurgery (nose and skull base surgery), head and neck surgery, throat microsurgery, department of voice and speech diseases, and pediatric otolaryngology has greatly enriched the content of otolaryngology. [0003] Otolaryngology often requires drug delivery devices to apply medicine to the inside of the ENT. The existing drug delivery devices...

AI Technical Summary

Problems solved by technology

[0003] Otolaryngology often requires drug delivery devices to apply medicine to the inside of the ENT. The existing drug delivery devices generally do not have heat preservation devices. The lower temperature liquid medicine may irritate the relatively fragile inside of the ENT. There are some drug delivery devices that use electric heating blocks to keep warm, but generally the temperature of electric heating blocks is high, which is easy to destroy the medicinal properties of the liquid medicine. At the same time, there is no stirring mechanism, and the liquid medicine is prone to precipitation, which affects the efficacy of the medicine.
