Description

A hand-held liquid storage and suction oral cleaner

technical field

The invention belongs to oral care equipment, and in particular relates to a hand-held liquid storage and suction oral cleaner.

Background technique

Oral care is the cleaning and protection of the teeth, tongue, palate, cheeks and other parts of the oral organs. The oral cavity is an irregular cavity that is warm, moist, and directly communicated with the outside world. It is the head of the digestive tract and respiratory tract. Teeth are surrounded by gums and periodontal soft tissues, forming many narrow spaces between teeth and between teeth and soft tissues, which are easy to leave food and are not easy to be cleaned. Such an environment undoubtedly provides excellent conditions for the growth and reproduction of microorganisms. Under normal circumstances, due to frequent eating, a large amount of saliva secretion, and good oral hygiene habits, the oral cavity is kept in good health as a channel for gas, liquid and solid food, and the growth, reproduction and death of microorganisms are in a dynamic balance. A healthy mucous membrane and a good self-defense mechanism are a good barrier against pathogenic microorganisms. Coughing and swallowing reflexes ensure that the airway is not violated.

However, when fasting or drinking is required due to disease, trauma, surgery, etc., when artificial interventions such as airway, tracheal tube and gastric tube need to be inserted from the mouth, when the oral mucosa is ulcerated due to radiation and chemical treatment. With the reduction of sleep fluid secretion, the retention of oral secretions, and the abnormal proliferation of pathogenic microorganisms, this dynamic balance will be disrupted. In this case, oral care is essential.

Clinical practice shows that in the clinical rescue of critically ill patients, orotracheal intubation is usually required due to the critical condition [2-3], but oral care is far more difficult than nasal intubation, and a standardized method has not been established [4]. For such patients, because the oral cavity is in an open state, they cannot eat orally, and the oral environment, swallowing function, and saliva secretion function change, which makes oral bacteria easy to multiply and move down, becoming one of the direct causes of ventilator-associated pneumonia; In addition, for some common patients with high fever and surgery, due to the need to stay in bed for a long time, and the need to apply large doses of antibiotics to the patients, it is easy to cause dysbiosis in the patient's oral cavity, and it is easy to cause a series of complications such as stomatitis and oral ulcers. Therefore, in clinical practice, oral care plays an extremely important role in keeping the oral cavity and teeth clean, eliminating bad breath, preventing oral and respiratory tract infections and other complications.

The survey showed that about 60% of ICU nurses performed oral moistening 2 to 4 times/h for tracheal intubation patients, which could reduce mucous membrane dryness, and the frequency of oral care was ≥3 times/d. Under such a high-frequency operation, if the process is too complicated, it will inevitably increase the nursing burden of the operator, and also bring a bad nursing experience to the patient. In traditional oral care technology, nurses generally use disposable oral care bags and hemostatic forceps to pick up cotton balls to directly perform "scrubbing" oral care. However, this cotton ball back and forth intermittent "scrubbing" oral care technology has some disadvantages during use:

First, the cleaning efficiency is low. Because the sterile cotton ball is wiped with normal saline or oral care solution, this method is only suitable for the places where the sputum is easily accessible on the patient's oral surface, and the gap between the teeth and the tongue coating cannot be completely cleaned, and it is difficult to remove Oral odor and thick tongue coating often fail to achieve the cleaning effect, resulting in twice the effort.

Second, the operation process is cumbersome. The oral care package involves many supplies. It is necessary to prepare hemostatic forceps, a sufficient number of cotton balls, and pouring physiological saline in advance. There is no lighting during the scrubbing process, so it is difficult to see the inside of the mouth during cleaning. Often, after using a large number of cotton swabs or cotton balls to clean the oral cavity, the oral cavity cannot be cleaned thoroughly, which also adds the step of checking the patient's oral cavity with a flashlight and prolongs the operation time of the nursing staff; at the same time, the hemostatic forceps used Easy to damage the oral mucosa. All these require nurses not only to master the process of soaking and wringing cotton balls, but also to avoid the discomfort caused by excessive operation force to the patient. After the operation, the items need to be processed, and the number of cotton balls should be counted in time after each operation to prevent accidents from falling into the patient's mouth. And because of the possibility of contact with the patient's oral secretions during the operation, there is a possibility of potential infection.

Third, the expenditure on medical resources is relatively high. For oral care patients with doctor's orders q4h and q6h, the use of a large number of disposable oral care packages increases the expenditure of medical resources to varying degrees.

Fourth, for some patients with high fever and confusion, they cannot cooperate well with the operation to actively spit out the liquid in the mouth. Therefore, the traditional oral care technology may cause the liquid of the cotton ball to easily drip into the patient's mouth, causing the patient to accidentally inhale the liquid into the respiratory tract, resulting in choking or even suffocation.

At present, some improved oral cleaning equipment has a single function, which requires the cooperation of multiple appliances to complete the functions of liquid injection, brushing, and liquid suction, and needs to connect pipes to complete the injection and suction of cleaning liquid, and the operation is relatively cumbersome.
