Abstract

The invention discloses a medical ultrasonic probe with couplant releasing and recovering functions, and belongs to the technical field of ultrasonic probes. The probe comprises a probe body and a film covering assembly, wherein the probe body consists of a head part with a probe sound window and a handle part, the film covering assembly comprises a shell sleeved on the head part through a sliding mechanism, and a film covering mechanism which is arranged in the shell and covers a film on the head part, and a release assembly and a recovery assembly are arranged in the shell and are used for releasing and recovering a coupling agent on the surface of the film. The method has the advantages of simplifying the operation flow of ultrasonic inspection, avoiding frequent manual smearing and cleaning of the couplant on the ultrasonic probe, saving time and energy, enabling the inspection process to be smoother, avoiding the waste of the couplant by means of the release assembly in the process of rolling and replacing the sleeve film, synchronously recovering the residual couplant by the recovery assembly when the sleeve film is automatically replaced, avoiding manual frequent wiping, and improving the efficiency of ultrasonic inspection.

Description

Medical ultrasonic probe with couplant releasing and recycling functions Technical Field The invention relates to a medical ultrasonic probe with couplant releasing and recovering functions, and belongs to the technical field of ultrasonic probes. Background The ultrasonic diagnosis technology is a core technical means of clinical noninvasive diagnosis and is widely applied to all parts of the whole body for examination, and the ultrasonic probe is a key component for realizing ultrasonic imaging, and the cleaning and disinfection quality of the ultrasonic probe is directly related to the prevention and control of nosocomial infection and the diagnosis and treatment safety of patients. According to the risk grade classification of medical ultrasonic probes, the probes are classified into low-level, moderate and high-risk types, wherein body surface inspection probes contacting with complete skin belong to low-risk types, probes inspected by body cavities belong to moderate-risk types, invasive probes such as kidney puncture, intra-operative cavity ultrasound and the like belong to high-risk types, and different risk grades of probes are required to execute differentiated cleaning and disinfection requirements. In the current clinic, for low-risk probes, the cleaning and the disinfection of the ultrasonic probes are mainly performed manually, and after the ultrasonic probes are cleaned by an enzyme-containing wet tissue, the ultrasonic probes are cleaned by medical alcohol, a disinfection wet tissue or ultraviolet disinfection equipment. For moderate, high risk probes, a more complex disinfection process is required. However, even a low-risk probe has a plurality of inherent defects in a manual sterilization mode, namely on one hand, the manual operation is difficult to sterilize strictly and thoroughly, the problems of incomplete sterilization and nonstandard flow are easy to occur, the sterilization effect is not up to standard, and the serious hidden danger of cross infection exists, and on the other hand, the manual operation enables medical staff to directly contact body fluid, pollutants and sterilization reagents of patients, so that occupational exposure risk is greatly increased, meanwhile, the manual sterilization flow is tedious and takes longer time, the diagnosis and treatment efficiency of ultrasonic examination is severely restricted, and the clinical requirement of the outpatient peak period is difficult to meet. In addition, the manual smearing and cleaning of couplant in the ultrasonic examination process further aggravates the burden of clinical operation. Medical staff needs to manually finish the residual cleaning of the probe and the skin after the couplant is smeared and checked in the traditional mode, so that the couplant is easy to waste and pollute the environment, the probability of pollution of the probe can be increased, and higher requirements are put forward for the follow-up disinfection process. In the prior art, although a part of the single-function couplant smearing device or probe disinfection equipment exists, the couplant smearing device or probe disinfection equipment is of an independent structure, the complete process integration connection of the automatic couplant supplying, cleaning and probe cleaning cannot be realized, and the requirements of high efficiency, standardization and safety of clinical ultrasonic inspection are difficult to be met at the same time. Therefore, an integrated device capable of integrating functions of automatically releasing and recovering couplant and automatically replacing the mantle of the ultrasonic probe is developed, and the problems of low efficiency, high risk, non-standardization and the like of the traditional manual operation are solved. Disclosure of Invention The medical ultrasonic probe with the couplant releasing and recovering functions can realize automatic smearing and automatic cleaning of the couplant of the ultrasonic probe, and meanwhile, automatic replacement of a probe sleeve film is completed, so that the problem of cross infection risks in the traditional operation is effectively solved. The technical problems to be solved by the invention are realized by adopting the following technical scheme: A medical ultrasonic probe having a couplant release and recovery function, comprising: The probe body consists of a head part with a probe acoustic window and a handle part; The film covering assembly comprises a shell sleeved on the head through a sliding mechanism, and a film covering mechanism which is arranged in the shell and covers the film covering on the head, wherein a release assembly and a recovery assembly for releasing and recovering the couplant on the surface of the film covering are arranged in the shell. As a preferred example, the sliding mechanism comprises a multi-gear groove arranged on the side face of the head part and a sliding cavity arranged in the shell, a pair of rollers are arranged at th
