Description

Invisible trachea cannula bite-block

Technical Field

The utility model relates to a medical auxiliary appliance, in particular to an invisible trachea cannula bite-block.

Background

The tracheal cannula is a respiratory channel of a critically ill patient, for example, when the patient is subjected to intracranial surgery, thoracotomy, general anesthesia surgery requiring a special body position such as a prone position or a sitting position, or general anesthesia major surgery in which neck tumors press the trachea, jaw, face, neck, five sense organs and the like, the tracheal cannula needs to be inserted in the trachea of the patient to help the patient to establish the respiratory channel. The trachea cannula is soft and is often bound with the tooth pad to prevent the trachea cannula from being bitten and deformed by the teeth of a patient, but for dysphoric patients, the trachea cannula is easy to be bitten into a shriveling shape because the severe movement of the tongue easily causes the trachea cannula to be separated from the tooth pad. Trachea cannula influences mechanical ventilation once being bitten and warp, probably causes the patient to suffocate, and inhales phlegm pipe and can't reach the air flue depths down to it is unable to go on to inhale inspection such as phlegm operation and fibre bronchoscope. Furthermore, the bite of the endotracheal tube during the fiberbronchoscopy can cause the outer surface of the fiberscope to scrape the wire or the inner light guide beam to break, resulting in the damage of the medical precision instrument.

At present adopt clinically to tie up bite-block and trachea cannula together, realize preventing that trachea cannula from being bitten the purpose of warping by the tooth, nevertheless bite-block and trachea cannula tie up together, and trachea cannula is fixed unstable and is removed easily, and limited oral cavity space becomes littleer, does not utilize the doctor to the observation of patient's oral cavity condition and the operation in the oral cavity, the oral care of the patient of being not convenient for more.

Disclosure of Invention

The utility model aims at overcoming the above-mentioned not enough of prior art and providing an invisible trachea cannula bite-block, on trachea cannula was located to direct cover, prevented the separation of trachea cannula and bite-block, effectively released oral cavity space can prevent patient's oral cavity palate damage simultaneously.

The technical scheme of the utility model is that: an invisible trachea cannula bite block comprises a bite block body, wherein the bite block body comprises a half body A and a half body B spliced with the half body A; the half body A and the half body B are both in a strip shape, arc-shaped grooves extending along the length direction of the half body A and the half body B are respectively arranged on the half body A and the half body B, after the half body A and the half body B are spliced to form a bite block body, the arc-shaped grooves of the half body A and the half body B are opposite to each other to form a cavity capable of clamping a tracheal cannula, and threading holes are respectively arranged on the half body A and the half body.

The utility model discloses further technical scheme is: the fixing belt is also included; the fixing belts respectively pass through the threading holes on the half body A and the half body B and are connected to the half body A and the half body B.

The utility model discloses still further technical scheme is: the outer diameter of one end of the tooth cushion body is gradually reduced to form a reducing section, and the end head of the reducing section is in smooth transition; the other end of the tooth cushion body is provided with two fixed wings which are symmetrically arranged, the half body A and the half body B are respectively provided with one fixed wing, and the threading holes are respectively arranged on the two fixed wings.

Compared with the prior art, the utility model has the following characteristics:

1. the utility model discloses a bite-block body cover is established in trachea cannula's outside, and the bite-block body is firmly inseparable with trachea cannula, and stable difficult removal has fine protection trachea cannula, makes its non-deformable. In the using state, the upper and lower teeth of the patient are respectively contacted with the half body A and the half body B, even if the patient tightly bites the dental pad body, the dental pad body can be combined more tightly, and the accidental occurrence of biting the dental pad body to the rack is prevented.

2. The utility model discloses a bite-block direct cover is established in trachea cannula's outside, has released the bigger space in oral cavity, only has a trachea cannula to the oral cavity space, and the oral care of being convenient for improves patient's comfort level.

3. The utility model discloses a bite-block body one end external diameter convergent and form the reducing section, the end smooth transition of reducing section department can prevent oral cavity maxilla damage.

4. The two fixed wings of the utility model protrude from the outer wall of the bite block body, can be used for connecting the fixed band, can be used as the incisor positioning points, and can prevent the tooth position from exceeding the fixed wings.

The detailed structure of the present invention will be further described with reference to the accompanying drawings and the detailed description.

FIG. 1 is a schematic view of the structure and the operation state of the present invention;

FIG. 2 is a right side view of FIG. 1;

description of the drawings: the securing straps are not shown in fig. 2.

Detailed Description

Example 1:

as shown in fig. 1-2, an invisible endotracheal intubation bite block comprises a bite block body, wherein the bite block body comprises a half body a1, a half body B2 spliced with a half body a1 and a fixing band 3.

Half A1 and half B2 are both strip-shaped, and are respectively provided with an arc-shaped groove extending along the length direction, after half A1 and half B2 are split into a cushion body, the arc-shaped grooves of half A1 and half B2 are opposite to form a cavity capable of clamping a tracheal cannula, and half A1 and half B2 are respectively provided with threading holes 41. The fixing strap 3 is connected to the half body A1 and the half body B2 through the threading holes 41 of the half body A1 and the half body B2 respectively.
