Combined type trachea cannula fixing device

Abstract

The invention discloses a combined type trachea cannula fixing device which is composed of two parts with symmetrical structures, wherein each part includes an elastic teeth cushion used for expanding and bracing the upper jaw and the lower jaw, an adjusting sliding block used for expanding and bracing the corresponding elastic teeth cushion, and an arc hoop used for fixing a tracheal catheter; each arc hoop is connected with the corresponding adjusting sliding block through a crank arm. In clinical application, the fixing device does not cause aching pain of the teeth due to overstress or harm to the oral cavity, teeth or lips of a patient, can provide stable support for the tracheal catheter, can be applied to tracheal catheters with various specifications and sizes, and is suitable for various patients with individual difference; the fixing device is ingenious in structural design, relatively easy to manufacture and implement, low in cost, and relatively convenient to mount, dismount and adjust, and can be operated by one person.

Description

technical field [0001] The invention relates to a medical device, in particular to a fixing device for clinical tracheal intubation. Background technique [0002] Endotracheal intubation refers to the technology of inserting a special endotracheal tube into the trachea through the glottis, which can provide the best conditions for airway patency, ventilation and oxygen supply, respiratory tract suction and prevention of aspiration, etc. It is widely used in clinical operations, Anesthesia, emergency resuscitation and other medical operations. The safe fixation of the oral endotracheal tube is a necessary guarantee for the effective ventilation of the patient through the endotracheal intubation. At present, after successful intubation, a tooth pad is usually placed to prevent the patient from biting the tube, and then the endotracheal tube is fixed with the help of adhesive tape or tape.

Problems solved by technology

The safe fixation of the oral endotracheal tube is a necessary guarantee for the effective ventilation of the patient through the endotracheal intubation. At present, after successful intubation, a tooth pad is usually placed to prevent the patient from biting the tube, and then the endotracheal tube is fixed with the help of adhesive tape or tape. Effective fixation, this operation method has many shortcomings: ①Traditional tooth pads are usually made of hard plastic that is not easy to deform, which is easy to cause damage to the oral mucosa of the patient, and there is a greater risk of oral infection, and the contact surface with the upper and lower teeth is relatively small. Small, local teeth are prone to soreness due to long-term conflict with them, and the comfort is poor; ②Dental pads are usually fixed with the endotracheal tube by tape before intubation, and the fixed position is only determined by experience, often intubation After the completion, it was found that the position of the dental pad on the endotracheal tube was not appropriate, and it was very inconvenient to adjust its position; ③ After the intubation was completed, the endotracheal tube and the dental pad were fixed with tape or tape, and the fixing method was relatively simple , the operation is more troublesome, and the fixation effect is not good. The endotracheal tube is often prone to displacement due to the large floating amount, and in severe cases, the tube may even be detached, endangering the life of the patient; ④ This operation method is more troublesome and often requires at least two people Collaborative completion reduces medical efficiency

However, it still has the disadvantages of poor comfort and easy damage to teeth and oral mucosa.

And when fixing the endotracheal tube, it is necessary to swing and adjust the position of the endotracheal tube to make the endotracheal tube fall into the fixing slot, which will easily bring discomfort to the patient and even cause damage to the respiratory tract
