Description

A tracheal tube

Technical Field

The utility model relates to the technical field of medical supplies, in particular to a tracheal cannula.

Background Art

Endotracheal intubation is a medical procedure in which a flexible tube is inserted into the patient's trachea to ensure an open airway and provide mechanical ventilation. This procedure is usually performed in situations where intubation is necessary, such as severe breathing difficulties, the need for prolonged mechanical ventilation, coma, or the need to maintain ventilation during surgery. Endotracheal intubation can be performed by experienced doctors or professionals in appropriate settings.

Announcement No. CN219662551U discloses an endotracheal tube capable of effectively supplying oxygen, comprising an endotracheal tube body, wherein the outer sliding sleeve of the endotracheal tube body is provided with a sliding sleeve; a first strap and a second strap are fixedly provided on the sliding sleeve, a Velcro fleece surface is fixedly provided on the first strap, a Velcro hook surface is fixedly provided on the second strap, the Velcro fleece surface is matched with the Velcro hook surface, and the endotracheal tube body is fixed by means of straps and Velcro, but when the sliding sleeve is fixed on the endotracheal tube, the endotracheal tube is easily deflated when the spring and the splint clamp the outer wall of the tube due to the relatively soft material of the endotracheal tube, thereby affecting ventilation.

So we proposed a tracheal intubation to solve the above problems.

DETAILED DESCRIPTION

The technical solutions in the embodiments of the utility model will be described clearly and completely below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only a part of the embodiments of the utility model, rather than all of the embodiments. It should be noted that the words "front", "back", "left", "right", "up" and "down" used in the following description refer to the directions in the drawings, and the words "bottom surface" and "top surface", "inside" and "outside" refer to the directions toward or away from the geometric center of a specific component, respectively. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

Please refer to Figures 1-3. The utility model provides an endotracheal cannula, including an endotracheal cannula body 1. A support frame 2 is arranged inside the endotracheal cannula body 1. As shown in Figure 2, the support frame 2 is made of steel wire, and its spiral structure is embedded in the inner wall of the endotracheal cannula body 1 and extends along the axial direction of the endotracheal cannula body. The setting of the support frame 2 supports the endotracheal cannula body 1 without affecting its bending, so as to ensure smooth ventilation in the endotracheal cannula body 1, and the support frame 2 can improve the toughness of the endotracheal cannula body 1, so that medical staff can perform intubation. A limit stop ring 3 is slidably installed on the outer side of the endotracheal cannula body 1, and a strap 6 is arranged on the outer side of the limit stop ring 3. The strap 6 is used to tie it to the patient's neck or ear to fix the limit stop ring 3 during treatment, and a locking mechanism 4 for fixing the limit stop ring 3 is arranged on one end of the limit stop ring 3.

Specifically, as shown in FIG. 3 , the locking mechanism 4 includes a plurality of extended strips 41 arranged along the circumference of the limit stop ring 3. The extended strips 41 extend along the axial direction of the limit stop ring 3, and one end thereof away from the limit stop ring 3 is inclined toward the outer side of the limit stop ring 3 (in a petal shape). The inner wall thereof is an arc-shaped surface, and the diameter thereof is the same as the inner diameter of the limit stop ring 3 and is slightly larger than the outer diameter of the endotracheal tube body 1. The outer sides of the extended strips 41 are all provided with external threads, and the outer sides of the plurality of extended strips 41 are threadedly connected to the same locking ring 42. When the locking ring 42 is located When the endotracheal tube body 1 is inserted into the trachea of the patient, the sliding limit stop ring 3 is aligned with the outside of the patient's mouth, and then the locking ring 42 is rotated to make it rotate to the end of the extension strip 41 away from the limit stop ring 3, so as to tighten the multiple extension strips 41 to limit the endotracheal tube body 1.

As a preferred technical solution of the utility model: a plurality of edges are provided on the outer side of the locking ring 42, and anti-slip teeth 43 are provided on the inner walls of the plurality of extension strips 41. The edges of the locking ring 42 facilitate medical staff to rotate the locking ring 42, and the anti-slip teeth 43 can increase the friction between the extension strips 41 and the outer wall of the endotracheal tube body 1, thereby improving the locking stability of the endotracheal tube body 1.

As a preferred technical solution of the utility model: a tooth pad 5 and a medical cotton pad 7 are arranged on the side of the limit ring 3 away from the locking mechanism 4, and the medical cotton pad 7 is located on the outside of the tooth pad 5. The tooth pad 5 can prevent the patient from biting the endotracheal tube body 1 during treatment. The setting of the medical cotton pad 7 can allow physiological saline or the like to be dripped on it to moisten the patient's mouth when the patient's mouth becomes dry and cracked during long-term treatment.
