Abstract
The utility model relates to a tooth protective sheath for a trachea cannula. The utility model is characterized in that the utility model is composed of a tooth sheath for the upper jaw and a lower jaw support, wherein both ends of the lower jaw support are respectively connected with the tooth sheath for the upper jaw, the tooth sheath for the upper jaw is in a half round arc shape which is consistent with the upper teeth of a person, and the front wall of the center of the half round arc shape of the tooth sheath for the upper jaw is provided with a V-shaped depression. The utility model has the advantages that the tooth damage in the process of inserting the cannula in the trachea is reduced, the medical disputes between the doctors and the patients are reduced, the patient satisfaction is increased and simultaneously no difficulty of inserting the cannula in the trachea is brought to the doctor.
Description
Technical field
This utility model relates to a kind of cleaning of teeth cover that is used for tracheal intubation, relates in particular to the anesthesia process of using anesthesia equipment in a kind of operative treatment, is specially adapted to tracheal intubation wherein.
Background technology
Tracheal intubation is general anesthesia management of respiratory, cardio-pulmonary resuscitation, patient's ICU rescue and must operating of treatment, has clinical practice widely, when tracheal intubation is brought many advantages, also cause some problems, wherein injury of teeth is the most common in the anesthetic intubate process, also is the patient to one of main complaint of anesthesia doctor.Portion during 1977 to 1986 studies show that injury of teeth accounts for 1/3rd of whole complaints the patient in the intubate process in the complaint of medical protection association; A in addition investigation shows that patient's injury of teeth ratio of 1,135,212 tracheal intubatioies is 1: 1,000; The ratio that also has a patient who studies show that tracheal intubation that the perioperative injury of teeth takes place is 1: 4,537, and wherein the patient's injury of teeth of half occurs in the tracheal intubation process, and actual ratio may be higher.
The tooth of the upper jaw, especially the left cut tooth is modal damage location, studies show that 78% damage occurs in maxillar part, 91% incisor that occurs in the upper jaw wherein, odontoseisis takes place in 41% patient, 47% the tooth fracture takes place, 10% tooth is deviate to occur among the patient of injury of teeth, the normal patient of tooth only accounts for 24.3%, fracture of tooth is modal damage, comprises that part fractures and all fractures, in addition because injury of teeth also may cause other severe complications more, comprise infection, hemorrhage, loss of tooth causes respiratory tract obstruction, jeopardizes patient's life.
Summary of the invention
The purpose of this utility model is a kind of cleaning of teeth cover that is used for tracheal intubation that reduces injury of teeth in the tracheal intubation process of invention.
For realizing above purpose; the technical solution of the utility model provides a kind of cleaning of teeth cover that is used for tracheal intubation; it is characterized in that; form by upper jaw facing and supporter; the two ends of supporter are connected with the maxillary teeth cover respectively; described upper jaw facing presents with the people goes up the corresponding to semicircular arc of tooth, and described upper jaw facing semicircular arc center antetheca is provided with V-type depression.
The longitudinal section of described upper jaw facing semi arch is a U type groove, and U type groove is divided into preceding cell wall, back cell wall and kerve wall, and preceding cell wall height is 14-30mm, back cell wall is lower than preceding cell wall, the cell wall thickness of upper jaw facing is 1-4mm, and is big more the closer to kerve thickness, and the thickness of kerve wall is 4mm.
Described kerve wall outer surface is provided with anti-skid design.
Described maxillary teeth cover material is macromolecular materials nontoxic, harmless, tasteless and that hardness is different, and upper jaw facing is inboard soft, and outside hardness is big.
This utility model is made the cleaning of teeth cover shape of the upper jaw, be enclosed within on patient's maxillary teeth, patient's teeth is protected in the tracheal intubation process, the main cause that injury of teeth takes place in the tracheal intubation process is that laryngoscope blade strength is too concentrated, soft outer hard in the upper jaw facing of the present utility model, the kerve wall of upper jaw facing is thicker, can disperse and cushion the pressure of laryngoscope blade, and single-point pressure is decomposed into multiple spot pressure; The damage that impressed pressure when the inner face of facing can cushion intubate causes the direct compressing of tooth and gingiva; Upper jaw facing semicircular arc center antetheca is provided with V-type depression, and compressing frenulum of upper lip when avoiding using can be determined the position of facing simultaneously; Kerve wall outer surface is provided with anti-skid design, the mucus covering surfaces causes frictional force to reduce after avoiding facing to insert the oral cavity, laryngoscope blade skids in the cover surface, this utility model material is thin and well coincide with the oral cavity of China ethnic group, thereby can reduce the influence of facing for the tracheal intubation opening visual field and operation itself to the full extent.
The utility model has the advantages that and reduce injury of teeth in the tracheal intubation process, reduce the medical tangle between the doctors and patients, increase patient's satisfaction, bring difficulty can for simultaneously doctor's tracheal intubation.

The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
Embodiment
As shown in Figure 1; for being used for the cleaning of teeth nested structure sketch map of tracheal intubation; the described cleaning of teeth cover that is used for tracheal intubation; it is characterized in that; supporting 2 by upper jaw facing 1 and lower jaw forms; the two ends of lower jaw support 2 are connected with upper jaw facing 1 respectively, and described upper jaw facing 1 presents with the people goes up the corresponding to semicircular arc of tooth, and upper jaw facing 1 semicircular arc center antetheca is provided with V-type depression 3.
As shown in Figure 2; be cleaning of teeth cover longitudinal section cutaway view; the longitudinal section of described upper jaw facing 1 semi arch is a U type groove; U type groove is divided into the preceding cell wall 4 that contacts with the dental arch outside; with the back cell wall 5 that contacts on every side in the dental arch; the kerve wall 6 that contacts with occlusal surfaces of teeth; consistent with people's tooth height; preceding cell wall 4 height are 14-30mm; back cell wall 5 is lower than preceding cell wall 4, and the cell wall thickness of upper jaw facing 1 is 1-4mm, and is big more the closer to kerve thickness; the thickness of kerve wall 6 is 4mm, is provided with anti-skid design at kerve wall 6 outer surfaces.
Upper jaw facing 1 material is macromolecular materials nontoxic, harmless, tasteless and that hardness is different, can make with the compression moulding of SEBS material, injection moulding or other molding methods, the macromolecular material bigger with another hardness is pressed into thickening layer, makes upper jaw facing 1 inboard soft, and outside hardness is big.
