Description

An esophageal ultrasonic bite mouthpiece for preventing pressure sores

Technical Field

The utility model relates to a medical device, in particular to an esophageal ultrasonic bite for preventing pressure sores.

Background Art

Pressure sores, also known as pressure injuries, are localized injuries to the skin or subcutaneous tissue, usually occurring at bony prominences, or at sites of contact with medical devices or other equipment. If the same position is maintained for a long time, pressure will continue to be applied to the same part of the body, which will inhibit blood circulation in that part, causing it to become red, painful, and ulcerated, forming a pressure sore. The main causes of pressure sores are long-term pressure on the same part, unclean skin, and a decline in physical health. The prevention of pressure sores is very important, as once they occur, they will cause physical and psychological trauma.

In the past decade, transesophageal ultrasound has been widely used in cardiac surgery. It plays a very important role in preoperative diagnosis, intraoperative heart function monitoring and postoperative surgical effect evaluation. At present, a mouthpiece is routinely used when transesophageal ultrasound is used in cardiac surgery. The mouthpiece protects the patient's teeth and lips from scratches during ultrasound operation, and protects the esophageal ultrasound probe from tooth damage.

At present, most of the commonly used bites are universal, which can be used for transesophageal ultrasound examination, gastroscopy, fiberoptic bronchoscopy, etc. This universal bite is made of hard plastic, with a hard material, and is mainly used to protect the inspection probe. For example, a bite for intraoperative transesophageal ultrasound is disclosed in Chinese patent CN201920596175.1. Among them, the examination time of gastroscopy and fiberoptic bronchoscopy is short, and the patient is in a clear or light anesthesia and sedation state during the examination. The universal bite has a short time to press the patient's lips, small damage, and a low incidence of pressure sores. However, cardiac surgery takes a long time and is traumatic. The time of transesophageal ultrasound is long, and the patient is deeply anesthetized and sedated during the operation. He may experience hypothermia, extracorporeal circulation, poor physical condition, etc. At this time, the universal bite will cause long-term compression on the patient's lips, which will lead to poor local circulation of the lips. Further combined with the patient's long-term hypothermia, extracorporeal circulation and surgical trauma during the operation, it is easy to cause pressure injuries to the patient's lips, and ultimately lead to the occurrence of postoperative oral herpes, ulcers, and pressure sores.

At present, gauze is usually wrapped between the patient's lips and the bite mouth after the bite mouth is inserted to reduce pressure. However, during the long-term and repeated operation of the esophageal ultrasound probe, the gauze will loosen and lose its decompression effect, resulting in protection failure; and the wrapped gauze occupies a large space, resulting in insufficient space in the mouth to place the tracheal tube bite pad. Cardiac surgery patients usually recover in the intensive care unit with tracheal tube sedation and mechanical ventilation after surgery. Therefore, after the operation, the anesthesiologist needs to remove the esophageal ultrasound probe and the hard universal bite mouth, and then insert the tracheal tube bite pad to fix the tracheal tube. Repeated intraoral operations increase the risk of damage to the patient's lips and teeth.

Chinese patent CN201310016757.5 discloses a mouthpiece, which includes a hard tube and an elastic covering member coated on the surface of the hard tube. The hard tube includes a tube body, a channel arranged in the tube body, a tongue depressor arranged on one side of the tube body, a bite portion adjacent to the tongue depressor, and a stopper connected to the bite portion away from the tongue depressor; the elastic covering member includes a covering body, a positioning portion coated on the surface of the channel adjacent to the tongue depressor, and an elastic stopper correspondingly coated on the stopper. This scheme is mainly an improved endotracheal tube fixing device, which mainly avoids the endotracheal tube from being blocked by the user's bite deformation and uses its elastic covering member to avoid the user's tooth breakage, oral mucosal damage and infection. However, the design of this scheme cannot be used for esophageal ultrasound examination, because it is actually used for dental pads to prevent pressure sores, and there is an essential difference in structure from esophageal ultrasound bite mouthpieces to prevent pressure sores.

Therefore, it is necessary to propose a new transesophageal ultrasonic bite for preventing pressure ulcers.

DETAILED DESCRIPTION

The utility model is described in detail below with reference to the accompanying drawings and specific embodiments.

Example 1

An anti-pressure ulcer esophageal ultrasonic bite, as shown in FIG1 and FIG2 , comprises a bite device body 1 , an endotracheal tube tooth pad 3 and a plastic connector 4 ;

The bite device body 1 includes a bite tube 5, a lip side pad 2 and a lip baffle 6; a through hole for passing the ultrasonic probe is provided on the lip baffle 6; one end of the bite tube 5 is connected to the outside of the lip baffle 6; the lip side pad 2 is arranged on the lip side of the lip baffle 6;

The tracheal tube mouthpiece 3 is connected to the mouthpiece body 1 via a plastic connector 4 .

More specifically, in this embodiment:

The esophageal ultrasonic bite block comprises a bite block body 1 and an endotracheal tube bite pad 3 connected via a plastic connector 4 .

The mouthpiece body 1 further includes a lip baffle 6, a lip side pad 2 and a bite tube 5. The lip baffle 6 is connected to the outside of the bite tube 5, and the lip side pad 2 is bonded to the lip side (inside) of the lip baffle 6. A through hole is provided in the center of the lip baffle 6 for allowing the esophageal ultrasound probe to pass through; the bite tube 5 is connected to the through hole to form a guide channel for allowing the esophageal ultrasound probe to pass through.

When the bite device body 1 is in use, the bite tube 5 is placed between the upper and lower incisors in the oral cavity and bitten tightly, and the esophageal ultrasound probe is inserted through the through hole in the middle of the lip baffle 6 to pass through the bite tube 5. The hard channel wall formed is used to protect the ultrasound probe from being scratched by the incisors, and also protects the incisors from loosening and damage during ultrasonic operation; at this time, the lip baffle 6 is against the lip surface to prevent the bite tube 5 from excessively extending into the oral cavity, and at the same time protects the lips from being scratched during operation of the ultrasound probe; the lip side pad 2 is attached to the lip surface, effectively reducing the stress of the hard lip baffle 6 acting on the lips, and can protect the skin and soft tissue of the lips for a limited time.

Furthermore, the free end of the bite tube 5 (the end extending into the oral cavity) is flanged outward so that the diameter of the flange is larger than the diameter of the bite tube 5, thereby preventing the bite tube 5 from easily slipping out between the teeth; the lip side pad 2 is made of hydrogel material, which can keep the lips moist while reducing the bite stress.

The tracheal tube tooth pad 3 and the mouthpiece body 1 are made of the same hard plastic, so that the components have sufficient strength to be fixed and limited with the tracheal tube; the plastic connector 4 is made of soft plastic and can be torn or broken off under the action of external force. In order to further meet the need to break the plastic connector 4 during use, a groove can be provided on the plastic connector 4, and the position of the groove can be designed according to the use requirements to avoid affecting or injuring the patient after breaking; the setting of the groove can facilitate the doctor's operation and reduce the operation time in the patient's mouth. Specifically in the esophageal ultrasound bite, when the esophageal ultrasound probe and the mouthpiece body 1 are pulled out at the end of the operation, the plastic connector 4 is torn off, and the mouthpiece body 1 is removed, leaving the tracheal tube tooth pad 3 fixed to the tracheal tube.

When using this esophageal ultrasound bite:

After the patient's tracheal tube is inserted, the patient's mandible is supported with both hands to open the patient's mouth, and the bite tube 5 and the tracheal tube tooth pad 3 are placed in the patient's mouth as a whole. The tracheal tube tooth pad 3 is close to the tracheal tube and the tracheal tube and the tracheal tube tooth pad 3 are fixed and limited with silk tape; the patient bites the bite tube 5 with the upper and lower incisors to limit the bite device body 1, and at this time, the lip baffle 6 is cushioned on the patient's lips through the lip side pad 2 made of hydrogel.

The esophageal ultrasound probe is placed into the oral cavity through the through hole in the center of the lip baffle 6, and is slowly inserted into the esophagus with the guidance of the bite tube 5.

After the operation, pull out the esophageal ultrasound probe, gently tear off the plastic connector 4, separate the bite block body 1 and the tracheal tube bite pad 3, support the patient's mandible with both hands to open the patient's mouth, gently take out the bite block body, and the tracheal tube bite pad 3 remains in the mouth and fixed to the tracheal tube.

The use of this esophageal ultrasonic bite can effectively reduce the patients' oral herpes pressure sores caused by long-term bite pressure; at the same time, it can also reduce the anesthesiologist's operation in the patient's mouth and reduce the damage to the patient's lips and teeth.

The above description of the embodiments is to facilitate the understanding and use of the utility model by those skilled in the art. It is obvious that those familiar with the art can easily make various modifications to these embodiments and apply the general principles described herein to other embodiments without creative work. Therefore, the utility model is not limited to the above embodiments, and improvements and modifications made by those skilled in the art based on the disclosure of the utility model without departing from the scope of the utility model should be within the scope of protection of the utility model.
