Description

A funnel-type press bottle for disinfectant

technical field

The invention relates to the field of medical instruments, in particular to a funnel-type pressing bottle of disinfectant.

Background technique

When disinfecting patients clinically, most of them use cotton balls dipped in venom for disinfection. Each time when sterilizing patients, the bottle cap needs to be opened, and cotton balls are used to dipped in venom. Repeated operations are easy to contaminate the disinfectant, and the disinfectant is easy Dripping, the operation is very troublesome and laborious, which adds great difficulty to the medical staff.

The patent application document with the application number of 201220190848.1 discloses a disinfectant bottle with an operation hole in the middle of the bottle cap, a connecting shaft on the operation hole, a pressing groove in the center of the circular cover, and a drainage channel at the lower end of the pressing groove. canal. When sterilizing the patient, turn the circular cover to remove the venom from the operation hole, and squeeze out the excess liquid by pressing the groove. When sterilizing the patient, the operation is simple, time-saving and labor-saving, and it can avoid controlled disinfection. However, when the cotton ball is dipped in the disinfectant to remove the venom, it still needs to be soaked in the disinfectant, and repeated dipping will still cause the disinfectant infection.

The utility model document with the application number of 201420129760.8 discloses a splash-proof disinfectant bottle. A water drainer is installed at the neck of the bottle body. After the cotton swab is dipped in the venom, the disinfectant on the cotton swab is pressed through the opening in the lower part of the drainer. , squeeze out the excess disinfectant to prevent too much dipping and removing the venom from splashing the disinfectant droplets on the worktable. Although the technical solution solves the problem that the disinfectant is easy to drip after dipping, it is still necessary to remove the cotton swab during the dipping process. Reach into the disinfection bottle and squeeze it in the drainer to make the disinfectant return to the disinfection bottle. The whole operation process completely exposes the disinfection bottle to the use environment, the cotton swab dipped in it, the impurities in the indoor air and the drainer itself. , are easy to contaminate the disinfectant.
