Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of nasal negative pressure suction, in particular to a nasal negative pressure suction tube facilitating secretion extraction. BACKGROUND

[0002] The nose is the starting part of the respiratory tract and the olfactory organ, which is composed of the external nose, nasal cavity and paranasal sinus, and is made of nasal bone, nasal cartilage, nasal muscle and covering skin. The nasal cavity is divided into left and right cavities by the nasal septum, and is connected to the outside world through the nostrils in front and to the nasopharynx in the back. The front part of the nasal cavity is the anterior nasal vestibule, which is lined with skin and has nasal hair, playing a filtering role and being prone to boils. The back part is the intrinsic nasal cavity, which is lined with mucosa and can be divided into the olfactory and respiratory parts, playing the roles of olfaction, warming and humidifying, and purifying inhaled air. The paranasal sinus is a gas-filled cavity in the skull around the nasal cavity, which is connected to the nasal cavity through the mucosa. When the nasal cavity is inflamed, it can spread to the paranasal sinus, causing sinusitis. The paranasal sinus participates in the humidification and warming of inhaled air and plays a resonance role in pronunciation. The external nose is the part protruding from the face, which is supported by bone and cartilage and covered with skin. The external nose is shaped like a three-sided cone, protruding from the central face, with a narrow upper end, the nasal root between the eyes, a high protruding lower end, the nasal tip, and a central raised part, the nasal bridge, with the nasal back on both sides of the bridge and the nasal wings on both sides of the tip. The skin at the tip and wings is thick, rich in sebaceous and sweat glands, and closely connected to the deep subcutaneous tissue and cartilaginous membrane, making it prone to boils. When inflamed, local swelling can cause severe pain due to compression of nerve endings.

[0003] The nasal cavity is a space between the two sides of the skull, based on the bony and cartilaginous nasal cavity, lined with mucosa and skin. The nasal cavity is an irregular narrow elongated space with a narrow top and a wide bottom, with a larger anterior-posterior diameter than a smaller left-right diameter. The anterior nasal cavity starts at the anterior naris and ends at the posterior naris, connecting to the nasopharynx. The nasal cavity is divided into left and right cavities by the nasal septum, with the anterior nasal cavity connected to the outside world through the nostrils and the posterior nasal cavity connected to the pharyngeal cavity through the posterior naris. Each nasal cavity can be divided into two parts: the anterior nasal vestibule and the intrinsic nasal cavity. Nasal negative pressure suction therapy uses intermittent suction to extract air from the nasal sinus, creating a negative pressure in the sinus cavity, and through the suction tube, the secretion in the nasal cavity is quickly sucked out. However, the existing nasal negative pressure suction device usually only uses a single negative pressure tube, which is inserted into the patient's nasal cavity for secretion suction operation. The overall operation is usually completed by the experience of medical personnel, and it is difficult to keep the patient comfortable and fixed at all times. Improper operation by medical personnel can cause pain to the patient, making it difficult to move and affecting the normal operation and treatment effect. At the same time, medical personnel cannot accurately maintain the same pumping efficiency during the operation, which also affects the final suction effect, making it difficult to use in daily life. Therefore, there is an urgent need to design a nasal negative pressure suction tube that facilitates secretion extraction to solve the above problems. SUMMARY

[0004] The present application aims to provide a nasal negative pressure suction tube for facilitating secretion extraction, to solve the problem that the existing nasal negative pressure suction device is generally provided with only a single negative pressure tube, which is inserted into the nasal cavity of a patient to perform secretion suction operation, and the operation of the whole device can only be completed by the experience of medical staff, and the patient cannot be kept comfortable and fixed at all times, and the patient may feel pain due to improper operation of the medical staff, and the normal operation and treatment effect are affected, and the medical staff cannot accurately keep the same pipe extraction efficiency during the operation, which also affects the final suction effect, and is not conducive to daily use.
