Description

Nasal cavity non-stuffing septum negative pressure suction device

technical field

The utility model relates to a medical nursing device used for hemostasis and drainage of effusion after nasal septum deviation operation, in particular to a nasal cavity non-stuffing septum negative pressure suction device.

Background technique

Deviated nasal septum can be caused by factors such as growth and development, genetics, trauma, etc. Most people have deviated nasal septum, but most of them are mild deviations that do not cause any symptoms and do not require treatment. However, some people have obvious deviation of the nasal septum, which can cause symptoms such as nasal obstruction, headache, and epistaxis. The most effective treatment for this disease is surgery. So far, there are a large number of patients who need this kind of surgery, and it ranks first in the nasal surgery department of otolaryngology in most hospitals. However, this operation is prone to complications such as septal hematoma, secondary septal abscess, and septal perforation. In order to prevent the above complications, at the end of the operation, hemostasis material is generally used to compress the nasal septum on both sides of the nasal cavity to stop bleeding. There are also a few foreign and domestic medical institutions that use multi-point sutures in the nasal cavity to stop bleeding. The former is currently the most mainstream method of hemostasis due to its simplicity and ease of use, while the latter is difficult to popularize in primary hospitals due to its complex operation and extremely high technical difficulty. However, the former will bring great physical and mental harm to the patient for a period of time after the operation, which is specifically reflected in: ① Due to the dense sensory nerve endings in the nasal cavity, which are very sensitive, the stuffing will cause severe pain in the nasal cavity; ② Nasal ventilation is blocked after stuffing , the patient must breathe through the mouth, resulting in dry throat and sore throat; ③The stuffing causes the blockage of the Eustachian tube, causing pain in both ears and discomfort; , which is not conducive to postoperative recovery; ⑤referred pain in the head caused by nasal packing; ⑥tears cannot flow into the nasal cavity normally due to packing, frequent epiphora, conjunctival congestion and other discomforts; Difficulty and severe mental and emotional discomfort; ⑧When the packing material is removed, it will still cause severe pain, and even the pain will reach the deep part of the brain and cause painful shock and other serious consequences; ⑨The risk of infection caused by the packing material; ⑩Taking out A large amount of inflammatory exudation was produced in the posterior nasal cavity, and the pseudomembrane covered the wound surface, which resulted in nasal obstruction of the patient within 1-2 weeks after operation and prolonged the healing time. The above drawbacks urgently need to find a solution.

The drainage tube in the nasal cavity is a semi-elliptical tube, one side of the tube wall is flat, and the other side is oval-shaped. The plane of the tube wall can be better in close contact with the cartilage surface of the residual nasal septal bone. With the help of negative pressure, the hemostasis can be suppressed. The multiple small holes evenly distributed on the tube wall can drain the effusion from the small holes into the drainage tube. The end of the guide tube is connected to the upper port of the three-way valve, the middle port of the three-way valve is connected to the negative pressure ball, and the bottom port of the three-way valve is connected to the liquid storage chamber. After the nasal septum operation, insert the drainage tube of the nasal cavity non-stuffing septum negative pressure aspirator into the nasal septum operation cavity, so that the plane of the nasal drainage tube is close to the nasal septum, which plays the role of compression and hemostasis. When draining the effusion, squeeze the negative pressure ball , to generate negative pressure suction, the fluid in the nasal cavity is drawn out along the drainage tube, and flows into the fluid storage room for temporary storage of fluid.

The drainage tube is also provided with a lavage port, which is convenient for postoperative washing and disinfection. After the drainage tube is extended, it can go around the patient's cheek and hang behind the ear to solve the problem of fixing the whole device.

The drainage tube is specially designed with a staggered multi-groove structure inside the tube to prevent nasal congestion in the embedded section caused by negative pressure.

The bottom of the liquid storage chamber is provided with a valve, which can be released from the valve of the liquid storage chamber for processing after it is full, and the liquid storage chamber can be cleaned. This part can be used repeatedly.

The utility model has the advantages of simple structure and convenient use. It not only has the function of hemostasis after nasal septum operation, but also has the functions of flushing the operation cavity and draining the effusion in the operation cavity. It can eliminate the pain of postoperative packing, remove the pain of packing material again, promote postoperative healing and shorten postoperative recovery time. Compared with the stuffing method, this product can keep the nasal cavity breathing smoothly, without the pain caused by stuffing, and has the advantages of simple operation, easy organization and production of devices, and low cost.
