Description

Bite-block and oral secretion suction device with attract and wash function

Technical Field

The utility model relates to the technical field of medical equipment, in particular to a bite block with suction and flushing functions and an oral secretion suction device.

Background

In an intensive care unit, the application of mechanical ventilation by adopting an artificial airway is wide, and a patient is mechanically ventilated through an oral tracheal cannula. In the operation of oral cavity trachea cannula, often need use the oral cavity bite-block, the effect of oral cavity bite-block is for fixed trachea cannula, prevents that the patient from clenching trachea cannula under the unconscious condition. The oral cavity bite block generally comprises a hollow columnar bite block main body and two fixing wings. Medical personnel paste medical adhesive tape in the bite-block main part of stationary vane upper end when carrying out the operation of peroral trachea cannula, fix trachea cannula and oral cavity bite-block with medical adhesive tape together, fix two stationary vanes in the outside of the patient upper teeth and the outside of lower tooth, the bite-block main part of stationary vane lower extreme is chewed to the patient's of being convenient for tooth, prevents that oral cavity bite-block is whole to slide in the oral cavity.

When a patient conducts mechanical ventilation through the oral tracheal cannula, oral secretion is increased frequently, if secretion in the oral cavity of the patient is not cleaned in time, the secretion may overflow from the mouth, so that saliva-related dermatitis, pollution of an internal jugular vein catheter and pollution of bed sheets are caused, and ventilator-related pneumonia may be caused in serious cases. For critically ill patients, the development of associated infections not only increases medical costs, burdens on the patient, but also increases mortality.

In order to solve the problems, the disposable sputum suction tube is stretched into the oral cavity of a patient and is in direct contact with oral skin to suck oral secretions of the patient in the prior art, however, the sputum suction tube is frequently used to suck the oral secretions, the stimulation to the oral cavity of the patient is increased, more oral secretions are generated, and the sputum suction tube is in direct contact with the oral mucosa and can damage the oral mucosa. Patients are easy to restless and not cooperate when sputum aspiration nursing is carried out, and indirect negative effects are brought to the state of illness. For medical care personnel, the sputum suction operation procedure is complicated, and time and labor are wasted when sputum is frequently sucked.

CN207341997U discloses a trachea cannula, it has the flushing pipe and the suction tube that sets up independent work at main duct's pipe wall is embedded, through injecting into normal saline in the flushing pipe, thereby can dilute and wash the secretion around the gasbag, suction tube connects negative pressure suction device, the secretion that will dilute and wash through suction tube is inhaled out, thereby secretion around the clearance gasbag that can be quick, the work load that alleviates medical personnel also can play better cleaning action, keep the continuation of secretion suction, thereby can thoroughly be clean up the secretion. However, the irrigation tube and the suction tube are not communicated with each other, the irrigation tube cannot irrigate the suction tube, oral secretion is easy to remain in the suction tube, and the cleanliness of the tracheal intubation is affected.

according to the utility model, the suction passage and the flushing passage are arranged in the hollow pipe body of the bite block, so that the traditional bite block, the sputum suction pipe and the bite block cleaning device are combined together, and the structure is simple; when the suction tube is used, negative pressure is communicated to one end, far away from the oral cavity end, of the suction passage, oral secretion of a patient can be sucked from the suction hole at the oral cavity end of the hollow tube body sequentially through the suction passage and sucked from one end, far away from the oral cavity end, of the suction passage, and suction of the oral secretion of the patient is achieved. After the bite block sucks oral secretion for a period of time, flushing liquid such as normal saline is introduced into the flushing passage, and the flushing passage is communicated with one end of the suction passage, so that the flushing liquid can flow into the suction passage through the flushing passage and then flows out from one end of the suction passage far away from the oral cavity end, flushing of the suction passage is realized, the cleaning degree of the bite block is improved, and the bite block does not need to be frequently replaced. The bite-block of the utility model does not need to frequently use the disposable sputum-aspirating tube to be frequently inserted into the oral cavity of a patient to aspirate oral secretion, thus reducing the stimulation to the oral mucosa caused by frequently using the disposable sputum-aspirating tube. The utility model utilizes the bite block to suck the oral secretion of a patient, and can prevent the patient from being restless and uncoordinated during sputum suction nursing, thereby bringing positive influence on the state of an illness. For medical care personnel, the sputum suction operation procedure can be simplified, and the operation is convenient and efficient. Because the trachea cannula is fixed at one end of the hollow tube body of the bite block, which is far away from the oral cavity end, the trachea cannula can be prevented from being frequently fixed again due to frequent replacement of the cleaning bite block, the workload of medical personnel is reduced, and the pain of a patient is relieved.
