Description

An oral care instrument

technical field

The utility model belongs to the technical field of oral care instruments, in particular to an oral care instrument.

Background technique

The establishment of an artificial airway is one of the most commonly used and effective methods for treating critically ill patients in the ICU; however, 9%-70% of mechanical ventilation patients with endotracheal intubation will develop respiratory-related pneumonia, and the fatality rate is as high as 50%-69%; in recent years Recently, studies have shown that the oropharyngeal colonization of bacteria played a key role in the related factors of ventilator-associated pneumonia; colonized bacteria move down through oral secretions, exfoliated epithelial cells, and the outer wall of the endotracheal tube to become ventilator-associated pneumonia. Some researchers pointed out that the toothbrush is the most effective tool to remove plaque and stimulate the mucous membrane. At the same time, combined with the washing method, it can not only remove all kinds of dirt from various parts of the oral cavity and deep in the oral cavity, but also make bacteria in the mucous membrane, The adsorption capacity on the oropharynx and the wall of the cannula is obviously reduced, and it will be discharged with continuous flushing and suction, which has positive significance for the prevention of oral and lung infections.

An oral care instrument is proposed in Chinese Utility Model Patent No. CN201811425961.1. Its working principle is: after the installation of the present invention is completed, the mouthwash storage box can store ml of mouthwash. Patients are required to store a sufficient amount of mouthwash in advance for oral hygiene. Every time the mouthwash automatic suction button is pressed, the quantitative suction pump starts once and automatically sucks the mouthwash ml; when the nursing staff is nursing, after pressing the light source button, the observation lamp lights up to provide lighting, which is convenient Nurses observed the oral mucosa of patients before and after oral care. After pressing the start button of the brush head, the brush head can vibrate at high frequency driven by the vibration motor to clean the patient's oral cavity. Press the start button of the brush head once for the first gear mode with gentle force; press twice for the second gear mode and vibrate The frequency is higher, which is suitable for people with more oral secretions; if the button is not pressed, it is the normal gear. After pressing the spray button, both the spray pump and the suction pump start, the spray pump draws the mouthwash from the mouthwash storage box and sprays it in the patient's mouth through the spray port, and at the same time, the suction pump absorbs the mouthwash from the patient's mouth through the suction port. The final mouthwash is discharged through the water outlet. After pressing the suction button, the suction pump starts independently, which can remove oral secretions before oral care, replace the traditional oral suction operation before oral care, and can also be used to remove residual mouthwash after oral care; the present invention Can be cleaned and disinfected regularly. When cleaning and disinfecting, you only need to connect the spray port and the suction port with pipes, and then connect the cleaning port to the prepared disinfectant through the pipe, connect the water outlet port to a special pollution liquid collection container or a medical suction device, and press the suction button. It can clean and disinfect the entire pipeline system of the oral care instrument; if you only need to clean and disinfect the pipeline that sucks contaminated mouthwash and oral secretions, just put the brush head into the prepared disinfectant solution, and connect the water outlet The special polluted liquid collection container or medical suction device can clean and disinfect the pipeline for sucking polluted mouthwash and oral secretions separately by pressing the suction button. The special polluted liquid collection container can be removed for reuse after soaking and disinfection, or it can be directly discarded after one-time use.

However, when the device is in use, its keys are easily touched by mistake, thereby giving wrong commands to the device, thereby affecting the usability of the device. Therefore, this application proposes an oral care instrument for this problem.
