Bite block for suction type trachea cannula

Abstract

The invention discloses a bite block for a suction type trachea cannula. The bite block comprises a bite block body, a negative pressure suction tube and a bandage, the bite block body is cylindrical, a central through hole of the bite block body can allow a tracheal catheter to penetrate through, the bite block body comprises a hard tube section and a soft tube section, the hard tube section sequentially comprises an inner soft layer, a hard layer and an outer soft layer from inside to outside, a cavity is formed in the hard layer, a plurality of liquid inlet holes are formed in the hose section, one end of the hose section is connected with the outer soft layer, an opening penetrating through the cavity is formed in the end, close to the hose section, of the hard layer, a liquid outlet hole communicating the outside with the cavity are formed between the hard layer and the outer soft layer, one end of the negative pressure suction tube is fixed to the liquid outlet hole, the other end of the negative pressure suction tube is connected with a negative pressure suction device, the bandage is fixed to the outer wall of the outer soft layer, use is convenient, and the tracheal catheter is good in fixing stability.

Description

【Technical field】 [0001] The invention relates to the technical field of medical devices, in particular to the technical field of an aspirable dental pad for tracheal intubation. 【Background technique】 [0002] Endotracheal intubation is a technique in which a special endotracheal tube is placed into the trachea through the glottis of the patient to assist in ventilation. It is widely used in clinical emergency resuscitation, respiratory arrest rescue, surgical anesthesia, and airway opening. The traditional method of oral tracheal intubation is generally to insert the trachea first, place the dental pad, and then use adhesive tape to fix the endotracheal tube and the dental pad. The trachea after intubation, especially the trachea with oral intubation, needs to be properly fixed, so as to avoid prolapse problems caused by factors such as unconsciousness of the patient and biting the tube. [0003] The existing dental pads have the following defects: ①The material of the de...

AI Technical Summary

Problems solved by technology

[0003] The existing dental pads have the following defects: ①The material of the dental pads is generally hard material, which is easy to wear the oral mucosa and is difficult to fix, thus causing the patient to spit out or swallow the tube; ②The oral secretion of patients with oral tube placement There are usually a lot of objects, which will easily make the adhesive plaster that fixes the dental pad wet, which will cause the problem of weakening the stability of the fixation. At present, there is still no oral suction device that can sustain and uninterrupted suction in the industry; The connection effect is not good, and the trachea is easy to slip off
