Nasal cavity support frame, nasal cavity support frame bracket and method for manufacturing the nasal cavity support frame by microdrop spraying

Abstract

The invention discloses a nasal cavity supporting frame, a nasal cavity supporting frame bracket and a droplet jetting production method of the nasal cavity supporting frame, belonging to the fields of medical instruments and droplet jetting. The nasal cavity supporting frame is made of an elastic material and is of a net structure similar to the outline of a nasal cavity of a human body, and the inside of the net structure is of a communicated hollow structure, so that an air flow channel is formed; and an air inlet is formed in the bottom of the net structure, and an air inlet valve is arranged at the air inlet. The bracket is matched with nasal cavity supporting frame to use and is composed of a main body of which the outline is similar to the shape of the nasal cavity supporting frame, wherein the outer surface of the main body is provided with a groove inosculated with the net structure of the nasal cavity supporting frame, and a handle is also arranged at the bottom of the main body. The nasal cavity supporting frame is comfortable in wearing and convenient to take and place.

Description

technical field [0001] The invention relates to the field of medical equipment and droplet spraying, in particular to a nasal cavity bracket based on a droplet spraying manufacturing process and its manufacturing process design. Background technique [0002] Recently, a large number of patients with rhinitis, sinusitis and nasal polyps have emerged in major hospitals. According to experts, the golden autumn season is particularly prone to upper respiratory tract infections. Coupled with the large temperature difference between morning and evening and dust in the air, the incidence of nasal cavity diseases has increased sharply. What is particularly worrying is that many people suffer from nasal cavity diseases. Often left unchecked, the result has led to greater pain, and even affect the quality of life. Although rhinitis will not directly bring life-threatening to patients, its complications and hazards cannot be ignored. Clinically speaking, in the early stage of allergi...

Problems solved by technology

The disadvantages are: poor comfort, narrow applicable crowd, large volume and short service life

The disadvantages are: professional surgical implantation is required; the scope of application is relatively narrow, and only very difficult diseases will be implanted with a nasal cavity support frame; the nasal cavity support frame made of memory alloy material is very expensive; the metal material is relatively irritating to the nasal cavity, and the patient needs a long time Time is right, some patients have severe rejection and can only give up this treatment

[0008] CN201420453761.8 discloses "A Memory Alloy Nasal Bone Correction Bracket". The bracket is made of reticulated memory alloy and is more comfortable to wear, but it is not convenient to take it out, especially when taking it out, it needs to be hooked by pliers with hooks The mesh will extrude and deform it, which poses a certain safety hazard
