Description

Bite-block set for oral catheter

Technical Field

The utility model relates to the technical field of medical appliances, in particular to a bite block kit for an oral catheter.

Background

With the progress of modern medical technology, diseases which can be treated through operations are more and more, the proportion of general anesthesia in the existing operation anesthesia is more and more, and the proportion of general anesthesia operations is nearly 90% in Beijing Hospital. After general anesthesia, the patient has loose muscles and can not breathe freely, and needs to be ventilated manually and mechanically to ensure the oxygen supply of the organism. At present, oral tracheal intubation is mostly adopted, wherein the tracheal intubation refers to a technology of placing a special tracheal catheter into an airway from the mouth through a glottis, one end of the catheter is positioned in the trachea, and the other end of the catheter is connected with a breathing machine. After the operation is finished, the tracheal catheter is pulled out after the patient recovers the spontaneous respiration after anesthesia and revival. After the trachea is intubated, in order to prevent the trachea catheter from being occluded due to various reasons in the operation to cause asphyxia or unsmooth respiration, a tooth pad is arranged on the side edge of the intubation tube, which is a common method in clinic at present.

The existing bite block has the following problems: 1. the contact area between the common hard tooth pad and the upper and lower teeth is small, the stabilizing effect is not good, the stress of local teeth is large, and the teeth are easy to loosen and fall off, especially for patients with periodontal diseases. After general anesthesia, the oropharynx self-protection reflex of a patient in the anesthesia recovery period is not recovered, and at the moment, if the teeth fall off accidentally, the teeth fall into an airway to cause airway foreign matters, block the airway and cause the risk of asphyxia; 2. hard materials are mostly made of hard plastics, and the tongue body, the oral mucosa, the teeth, the gingiva and other tissues are injured by long-time compression in the operation. Especially, in the prone position, the tongue body and other soft tissues in the oral cavity can not be isolated from hard bodies such as tooth pads, tracheal catheters, teeth and the like, the injury of oral lips and the tongue body caused by long-time compression of the soft tissues in the oral cavity by the teeth, the tooth pads and the catheters can be easily caused, hematoma and huge tongue in the oral cavity can be caused after severe patients operate, the air passage is blocked, and even the breathing difficulty and suffocation can be caused after the tracheal catheter is pulled out.

SUMMERY OF THE UTILITY MODEL

The utility model aims to provide a bite block kit for an oral catheter, which can increase the stabilizing effect of the bite block on upper and lower teeth, and simultaneously avoid the damage to tissues such as a tongue body, oral mucosa, teeth, gum and the like, thereby reducing the risks of foreign matters in an airway, airway blockage and asphyxia caused by the fact that the teeth fall into the airway accidentally.

In order to achieve the purpose, the utility model provides the following technical scheme: the utility model provides a bite-block external member for passing through mouth pipe, every bite-block external member contains 2 groups bite-blocks, and every bite-block includes bite-block main part, spacing armguard, runs through the groove and pulls the strip, bite-block main part transverse section is isosceles trapezoid, just run through in the bite-block main part and be equipped with run through the groove, the symmetry is installed all around at the vertical both ends of bite-block main part spacing armguard, both sides between spacing armguard the bite-block main both sides form the tooth's socket, bite-block main part bottom is connected with pull the strip.

Preferably, the cross section of the bite block main body forms a base angle alpha of two sides of an isosceles trapezoid, and the base angle alpha ranges from 77.5 degrees to 85 degrees.

Preferably, the cross section of the bite block main body is in the shape of an isosceles trapezoid, wherein the upper part, the lower part and the height of the isosceles trapezoid are respectively L1-small, L1-large and H1.

Preferably, the length of H1 is equal to 2 times the length of L1-maxmas.

Preferably, the transverse section of the through groove is in an isosceles triangle shape, and the side of the through groove is parallel to the equal waist sides of the two sides of the bite block main body.

Preferably, the tooth socket width L4 is in the range of 6mm to 15 mm.

Compared with the prior art, the utility model has the beneficial effects that:

1. the bite block main body 21 is designed into an isosceles trapezoid shape, and the base angles alpha with different opening degrees are set according to different crowds, so that the applicable crowds of the bite block main body are promoted, the limiting protection arms 22 are fixedly installed on the two sides of the bite block main body 21 to prevent the bite block main body 21 from being displaced and loosened, tooth grooves are formed in the two sides of the bite block main body between the limiting protection arms on the two sides to accommodate 3-4 molars, the contact area between the bite block and the teeth is increased, the pressure of the bite block on a single tooth body during use of the bite block is reduced, the injuries such as tooth looseness, falling and the like caused by long-time pressure are prevented, the bite block is moved backwards to the molars on the two sides from the traditional upper and lower incisors, and the occlusion is more reliable; in addition, the mode of double bite blocks can be used for ensuring enough openness and avoiding the patient from biting the tracheal catheter.

2. Through the tooth socket that both sides formed about the bite-block main part and spacing armguard parcel tooth, keep apart the soft tissues such as the tooth body and the tongue body, oral mucosa, the damage appears after preventing oral soft tissue and the long-time contact of hard thing, pressurized, can set up the frictional force between the texture increase bite-block main part of undulation and the tooth simultaneously in the bite-block main part that lies in the bite-block bottom, prevents that the bite-block main part from sliding, further protects oral cavity and tooth.
