Description

A kind of tracheal intubation bite-block
Technical field
This utility model relates to medical device technical field, specifically refers to a kind of tracheal intubation bite-block.
Background technology
When suffering from ventilation or the needs of patients of dysfunction of ventilation in case of emergency carries out endotracheal intubation, need tracheal intubation conduit and bite-block to carry out with the use of, require that tooth is bitten bite-block and carried out being fixed conduit by patient.For ensureing good histocompatibility, tracheal intubation conduit is mostly flexible PVC material.
Current bite-block mostly is rigid plastics and makes, and easily causes the discomfort of conscious patient.The upper and lower wing of bite-block, when being engaged bite-block, being stuck between the lips and teeth of patient, thus playing fixing effect by patient.Due to bite-block upper and lower wing sharp edges and in flake structure, the oral cavity of easy injured patient.For old people and part comatose patient, because lower jaw and oral cavity laxity of ligament cause oral cavity not close, after inserting conduit, conduit moves up and down along with breathing, and the upper and lower wing of bite-block easily carries out sliding and the oral mucosa of injured patient in the oral cavity of patient.
Meanwhile, when being fixed conduit, needing to use adhesive plaster first conduit and bite-block to be wound around, then being fixed in the Face and cheek of patient.Some patients, to cloth hypersensitivity, often causes skin injury; The offset printing left over after simultaneously changing adhesive plaster is difficult to erasing, increases nursing work load.
In addition, in order to effectively prevent pulmonary infection, every day at least will carry out twice mouth care to the patient of tracheal intubation, all need thoroughly to remove fixed air cannula adhesive plaster before each mouth care, again it is fixed again after mouth care terminates, considerably increases the workload of medical personnel.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, the oral cavity providing the upper limb of a kind of solution due to bite-block and bottom wing displacement to rub to cause is impaired, can make tracheal intubation position relatively fixing, reduce patient's lip perimembranous skin damage and reduce the tracheal intubation bite-block of medical personnel's workload.
In order to achieve the above object, this utility model provides a kind of tracheal intubation bite-block, comprises the bite-block body with hollow structure and the flank being connected to bite-block body both sides,
Described bite-block main body is flat structure, and its outer radial cross section is that class is oval, and the axial direction outside bite-block main body is provided with arc-shaped concave, and the opening angle of described arc-shaped concave is less than 180 °;
Pad is provided with in the hollow structure of described bite-block main body.
Preferably, described bite-block main body adopts silica gel material to make.
Preferably, described flank adopts ethylene-vinyl acetate copolymer (English abbreviation: EVA) material to make.
Preferably, described flank is provided with fixing hole.
Preferably, described tracheal intubation bite-block also comprises fixing band, and one end of described fixing band is connected in fixing hole, and the other end of fixing band is connected and fixed device.
Preferably, described fixing band is the bandlet of wide plate structure.
Preferably, the side of described fixing band is provided with skin contacting adhesive layer, and the material of described skin contacting adhesive layer can be made up of any one in cotton, chinlon, terylene, flannel, silk or burlap.。
Preferably, described bite-block body is provided with concaveconvex structure, and described pad is located in the hollow structure of the bite-block body corresponding with concaveconvex structure position.
Preferably, described concaveconvex structure is cord tissue or groove structure.
Preferably, described flank is rectangular, fan-shaped, oval, circular, triangle, tetragon, or octagon.
Preferably, described flank symmetry is connected to the both sides of bite-block body end.
Preferably, the two ends of the outer edge of described flank are respectively equipped with two fixing holes.
Preferably, described fixture can be magic glue, paste band, fastener, button, or one or more in tether.
The beneficial effects of the utility model are: 1, rational in infrastructure, and flank can be fixed on outside lip, can not carry out sliding and causing oral injury in patient oral cavity; 2, use fixing band to substitute uses immobilization with adhesive tape in cheek portion in the past, reduces the risk of skin injury, and fixing band is easy to regulate, and facilitates the control of elasticity, without the need to changing every day before and after mouth care, decreases nursing work load; 3, adopt more soft material, increase patient comfort.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, this utility model is described further, but enforcement of the present utility model is not limited only to this.
Embodiment 1:
A kind of tracheal intubation bite-block as shown in Figure 1, comprise a bite-block main body 1 and two flanks 2, wherein said bite-block body 1 is flat structure, its outer radial cross section is that class is oval, axial direction outside bite-block main body 1 is provided with arc-shaped concave 3, the opening angle of described arc-shaped concave 3 is 90 °, and the inner side axial direction of bite-block body 1 is provided with circular hollow passage; Flank 2 is for having the sector structure of radian, and two described flank 2 symmetries are connected to the both sides of bite-block main body 1 end.
Described bite-block main body 1 adopts silica gel material to make, and adopts mutually plastic material to carry out making more soft than ever, but can bear again firmly being engaged of patient, thus increase patient comfort again while playing support; Described flank adopts EVA material to make, and during use, two flanks 2 is placed in respectively the outside of the upper and lower lip of patient.
