Paranasal sinus drainage retention device

Abstract

The invention discloses a paranasal sinus drainage retention device which comprises a retention tube and a puncture needle, wherein the puncture needle is arranged in the retention tube and penetrates through the retention tube; when the paranasal sinus drainage retention device is used, a puncture needle head is punctured into a nasal cavity of a patient, the puncture needle is pulled out after the puncture needle head arrives a designated spot, a plug is closed, an injector is inserted into a first check valve, proper amount of air is introduced according to the condition of the patient, then the injector is pulled out, an air bag swells, the retention tube is fixed in the nasal cavity, the injector is inserted into a second check valve, a cleaning liquid or medicine is injected into the nasal cavity through a washing tube and a sleeve tube, and the injector is pulled out after completion. The paranasal sinus drainage retention device is simple in structure, convenient to operate, safe and reliable, and can retain in a nose for a long period of time after puncture once, retention is realized under local anesthesia after puncture once, the effects of washing and injecting the medicine are achieved, the harm caused by unnecessary general anesthesia and repeated punctures on the patient is avoided, the infection risk caused by the repeated punctures is also reduced, and a sinus cavity is directly and accurately washed with the medicine.

Description

technical field [0001] The invention relates to a medical tool, in particular to a sinus drainage indwelling device. Background technique [0002] Inflammation of sinus mucous membrane, in various sinusitis, maxillary sinusitis is the most common, sinusitis can be single or multiple, the most common cause of disease is sinus suppurative inflammation secondary to nasal cavity infection, in addition, allergic reaction, mechanical Sexual obstruction and changes in air pressure can easily induce sinusitis. Tooth infection can cause odontogenic maxillary sinusitis. The usual treatment method is puncture and irrigation for sinusitis. The current sinus drainage tube used clinically is an epidural anesthesia catheter , is made of silica gel. During the operation, the surgeon needs to do sinus puncture first, and then introduce the epidural anesthesia catheter, which increases the difficulty of the operation for the surgeon. The sinus drainage tube is not easy to indwell for a long t...

Problems solved by technology

[0003] The purpose of the present invention is to solve the problem that the above-mentioned existing sinus drainage tubes are not easy to be left in place for a long time, each puncture requires general anesthesia, and repeated punctures cause harm to the patient, increase the pain of the patient, increase the recovery time of the disease, increase medical expenses, and increase the risk of surgery. Repeated puncture has the risk of infection, and it needs to be fixed on the external nose and face. It is difficult to stick and fix it with tape, which will increase the skin damage of patients. In clinical practice, there is a lack of direct puncture drainage and indwelling devices for sinusitis symptoms. drainage indwelling device
