Description

Automatic whole-course cleaning, sterilizing and storing cabinet for surgical instruments

Technical Field

The invention belongs to the technical field of medical instrument cleaning equipment, and particularly relates to an automatic whole-course cleaning, sterilizing and storing cabinet for surgical instruments.

Background

Conventional surgical instruments such as scalpel, surgical scissors, hemostatic forceps and suture scissors and the like relate to some special fields such as orthopedics, urology, gynaecology and obstetrics, burn branch of academic or vocational study, plastic surgery, brain surgery, cardiothoracic surgery, general surgery and the like and also need special instruments, for example in the operation process of gynaecology and obstetrics, different surgical instruments need to be used, instruments are often polluted by blood or tissue in the operation process, after the surgical instruments are used, the surgical instruments need to be cleaned and disinfected, the surgical instruments are cleaned and disinfected, for some small-size surgical instruments, the disinfection of the existing equipment is insufficient, and part of high-activity germs can not be effectively eliminated. At present, sterile distilled water is generally adopted for washing, and disinfectant is adopted for wiping or pasteurization, and because the treatment means is limited or some surgical instruments have complicated structures and dead corners which are difficult to treat, for example, manual cleaning is only carried out for simple washing, particularly for instruments containing blades, for instruments containing grooves and gaps, the dirt in the instruments is difficult to contact during manual cleaning, and the cleaning effect is not ideal. The surgical instruments are not thoroughly cleaned or residual fine tissues exist, bacteria are easy to breed, the surgical instruments are required to be sterilized again in the storage process or before use, and otherwise, cross contamination and even wound infection of patients can be caused. Because the existing treatment mode for cleaning and sterilizing the medical instruments is not strictly required and monitored, the cleaning and sterilizing degrees and the comprehensiveness are difficult to reach the standard.

Some current medical apparatus cleaning and sterilizing equipment focus on light washing of sterilization, and the scheme of sterilization has been considered and designed to its equipment focus, and the cleaning mode still adopts simple washing, and in to patient's operation in-process, the operation often can adhere patient's body fluid, blood and body hair, and some dirt are comparatively hidden, are difficult to discover or by the washing clean, carry the dirt and deposit the in-process, lead to surgical knife utensil etc. to nourish a large amount of bacteriums in the short time very easily to and deposit the relatively poor pollution of in-process, increase the operation risk. In addition, the existing cleaning and sterilizing mode for medical instruments only depends on a flushing mode, so that the defect that a large amount of water resources are consumed during cleaning exists. A sterilization cabinet that uses at present combines through modes such as ultraviolet ray, far infrared, high temperature or ozone or multiple mode, disinfect sterilization to articles such as medical apparatus, the cabinet boxlike structure of stoving saving, collect and deposit and the sterilization design as an organic whole, but only take the mode of washing to corresponding apparatus, perhaps blunt ware and sharp ware mix and wash, the cleaning degree is lower, the effect is poor, often not carry out sterilization treatment, only rely on sterilization case and sterilization cabinet, the cleanliness and the sterilization degree of apparatus do not reliably guarantee, because different apparatus sterilization treatment modes are different, sterilization case and the sterilization cabinet of current emphasis on depositing the function can't be effective sterilization treatment respectively to various different kinds of apparatus. A double-sided cleaning device for medical equipment with publication number CN 110180810A comprises a box body, a filling port, a partition board and an outlet; the right end of the partition board is provided with a turnover mechanism which rotates in the horizontal direction, the turnover mechanism comprises a turnover roller, a stationary contact, a contact support plate, an elastic block, an electromagnet and a conductive groove, and the arc-shaped surface of the turnover roller is covered with the two electromagnets; conductive grooves which are in one-to-one correspondence with the electromagnets are formed in the front end and the rear end of the overturning roller, and the conductive grooves are electrically connected to the corresponding electromagnets; and static contacts are correspondingly arranged on the outer sides of the conductive grooves on the two sides of the turnover roller and extend into the conductive grooves. When this scheme is scrubbed the equipment through the cleaning roller, the equipment upset through tilting mechanism in with the cleaning process again for reduce artificial participation degree, realize automatic upset and two-sided abluent function. The cleaning area of the cleaning machine is basically designed on the surface of the instrument, the cleaning machine cannot go deep into the interior of the instrument and a groove area, and the cleaning function of dirt in the instrument with a complex structure and a small space cannot be effectively realized.

The scheme can meet the requirement of instrument cleaning flow sequence, transfer various cleaning steps to subsequent procedures after finishing, and realize continuous and continuous cleaning operation. However, this solution requires the surgical instruments to be taken out and stored, at least during which the surgical instruments are exposed to the external environment again, which may cause secondary contamination, and thus the surgical instruments must be sterilized again during storage or before the next use, which still causes a problem of troublesome operation.
