Disposable freezing probe

Abstract

The disposable freezing probe includes integrated head, middle part and tail. The head has probe head possessing hollow probe cavity and inner pipe with interval in between and mounted in the front end of the handle. The middle part inserted into the cavity has input pipe and output pipe communicated separately with the inner pipe and the probe cavity. A temperature measuring wire is penetrated into the probe cavity. The tail has an outer shell, an inside casing, an isolating metal plate, a core axle integrated to the outer shell, input metal pipe and output metal pipe communicated separately to the refrigerant inlet and the refrigerant outlet, and temperature measuring leads connected to the system unit of the freezing treatment equipment.

Description

field of invention [0001] The invention relates to a freezing probe, in particular to a disposable freezing probe. Background technique [0002] Due to the limitations of the hardware conditions of the hospital, the stubbornness of the virus, and the unreasonableness of the disinfection method, etc., the pollution caused by the incomplete disinfection and sterilization of reusable medical devices has occurred continuously, and the virus has been transmitted to other patients who have been operated. Medical malpractice has led people to study disposable medical devices to ensure patient safety. Now, disposable medical devices have become an important part of modern medical practice and are widely used. Compared with reusable medical devices, disposable medical devices must greatly reduce their manufacturing costs, while the functions and performance of the devices must not be affected in any way, in order to be accepted by the majority of patients. This makes disposable med...

Problems solved by technology

However, the protective cover still cannot solve the disinfection problem of connecting joints and connecting hoses, etc., and also brings certain troubles to use, and it cannot guarantee sterility on the operating table.

Moreover, no matter how the sheath fits closely with the probe, it will also increase the thermal resistance, which will affect the introduction of cold energy from the probe to the human tissue, and will inevitably form a large temperature difference between the probe head and the outer wall of the protective sheath.
