An improved headgear is structured to secure a mask to the head of a patient and comprises a parietal support, an occipital support, and a zygomatic support connected together. The zygomatic support comprises a pair of zygomatic braces that are each structured to engage the face of the patient and to support the mask in fluid communication with the patient. The zygomatic braces each comprise at least one of a cephalic element structured to engage the face cephalic to the crest of the zygomatic bone, and a caudal element structured to engage the face caudal to the zygomatic bone.

An aiding apparatus for nasal tip plasty is useable in augmentation rhinoplasty. The aiding apparatus for nasal tip plasty includes a strut part and a holding part provided on a lower portion of the strut part and coupled to septal cartilage. Thus, a cartilage scaffold complex useable in nasal tip plasty may be easily prepared at the exterior of an operation space. This aiding apparatus allows substitution for the paired batten graft or paired spreader graft and easier execution of caudal septal extension graft. Further, a decreased amount of cartilage is used to execute the nasal tip plasty in a simple way, therefore easily making a pretty nose, in addition to shortening the operation time.

An airflow intrusive nasal relief and snoring stopping device is applied in an oral cavity. The oral cavity includes an oral opening, an upper tooth, a tongue, a palate and a uvula. The nasal relief and snoring stopping device includes a tooth accommodating member accommodating the upper tooth, and an airflow intrusive member between the uvula and the oral opening The tooth accommodating member includes a left tooth region and a right tooth region that are symmetrical. The airflow intrusive member connects the left tooth region and the right tooth region, and extends from the tooth accommodating member towards the palate. With the airflow intrusive member intruding the airflow inhaled through oral opening, soft tissues in the oral cavity are prevented from the effect of the airflow and hence from vibrations that may cause snoring, thereby improving symptoms of nose congestion and allergies.

The invention relates to the field of medical instruments, and discloses a harelip nasal columella retention clip. The harelip nasal columella retention clip comprises two splints used for clamping the two sides of the nasal columella and a connector used for connecting the two splints; the connector is shaped like an arc, and the two splints are located at the two free ends of the connector respectively; the opposite sides of the two splints are provided with plate-type supporting surfaces; the top of each splint is provided with a first supporting part used for supporting the nasal alar cartilage, and the bottom of each splint is provided with a second supporting part used for being supported at the basis nasi. According to the harelip nasal columella retention clip, the verticality andheight of the nasal columella can be effectively maintained through the nasal columella fixing splints, and then the nasal shape obtained after an operation is maintained. By wearing the retention clip, the position and form of the nasal columella can be maintained truly and effectively, and the purpose of maintaining the harelip nose shape is achieved.

A noseband for a horse bridle is specifically designed, structured and configured to direct the cheekpieces along the sides of the horse's face and away from the temporomandibular joint (TMJ) and nerves that run along the cheek bones, thereby avoiding TMJ damage, while also eliminating pressure at the horse's poll and back of the ears. A cheekstrap holds the cheekpieces snug against the opposite sides of the horse's face to discourage lateral (side-to-side) movement of the mandible (i.e., lower jaw) and undesirable displacement of the tongue out of the sides of the mouth while also assisting to hold the cheekpieces away from the TMJ and cheekbones.

The invention relates to a material used for an autologous cortical bone synostosis silica gel particle for nasal plasty and a preparation method of the material. The material structurally comprises a nasal bone base body made of the silica gel particle, the nasal bone base body comprises an apex nasi, a columella nasi and a nose ridge, the nose ridge is connected with the columella nasi through the apex nasi; the lower part of the nose ridge comprises two nose ridge sections arranged in a V shape in a crossing manner, a nasal bone of a human body is located between the two nose ridge sections to ensure that a prosthesis does not displace or abrade, the nasal bone base body is provided with a hollow body, and the hollow body is filled with an autologous cortical bone. The material and the preparation method have the beneficial effects that due to the design of the nose ridge section, the prosthesis is tightly in contact with the nose bone and does not displace or abrade; and a body fluid flows into a hole in the nose ridge to grow a human tissue, so that the stable fusion of the nose and the nose prosthesis is promoted, the nose prosthesis is prevented from moving, falling off or festering, and the pain of a patient is prevented after the operation. The method is suitable for treating the autologous or allogeneic bone synostosis silica gel particles.

The human head model 4 comprises an anterior portion 8 including a nose part 16 in which nostrils 16a are formed, and a main portion 40 including at least part of a nasal septum 44, at least part of a nasal cavity lateral wall 42, at least part of a sphenoidal sinus posterior wall 66, and at least part of an internal carotid artery 72. The liquid circulation means 6 comprises a storage tank 102 for storing a nontransparent colored liquid, a supply flow path 104 disposed between the storage tank 102 and the at least part of the internal carotid artery 72, a return flow path 106 disposed between the at least part of the internal carotid artery 72 and the storage tank 102, and a circulation pump 108 for circulating the liquid within the storage tank 102 through the supply flow path 104, the at least part of the internal carotid artery 72, and the return flow path 106.

A transparent nasal splint to be worn externally after a trauma, nasal surgery or nasal injection. The nasal splint has two nasal wall panels bridged together at a spine having an inverted-u shape cross section. The nasal wall panels are inwardly biased to apply compression and to grip onto the nose. The splint is made of semi-rigid material having suitable resiliency to allow moving of the nasal wall panels in an outward direction and to provide for the inward bias of the nasal panels when the splint is in use. The splint may have a nasal spine made of springs(s) or hinge(s) having suitable resiliency to allow moving of the nasal wall panels in an outward direction and to provide for the inward bias of the nasal panels when in use. The splint is also made of suitable material and design which render it being inconspicuous or not visually obvious.

The invention discloses a preparation method of nose prosthesis by using a gold triangular nose carving technology and a use method thereof. The method comprises the following steps: acquiring three-dimensional original data of the head shape of a patient; designing a preoperative 3A scheme in three aspects of aesthetic appreciation, dissection and analysis, establishing an oriental gold four-digit triangle aesthetic system, a 3D data measurement evaluation system, an autologous tissue sampling system, an exclusive muscle subsidence preoperative evaluation system and a three-level full-nose scheme design system, and constructing a three-dimensional simulation image after nose processing; and realizing the whole design around the large gold triangle of the nose.
