Description

sinus drainage indwelling device

technical field

The utility model relates to a medical tool, in particular to a sinus drainage indwelling device.

Background technique

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 time, and each puncture requires general anesthesia. Repeated punctures cause harm to the patient. Increase the pain of patients, increase the recovery time of the disease, increase medical expenses, increase the risk of surgery, and repeated punctures have a risk of infection. At the same time, it needs to be fixed on the external nose and face to achieve the effect of indwelling and drainage, which also brings troubles in fixing: 1. The anesthesia catheter is thin, and it is difficult to stick and fix it with tape; 2. The adhesive tape is fixed on the external nose and face, increasing the The risk factors of skin damage in patients increase the suffering of patients; 3. In order to reduce the skin damage of patients, anti-injury material adhesive tape is used, which indirectly increases the hospitalization expenses of patients; 4. The adhesive tape is fixed on the external nose and face like a "little cat", which affects the appearance of patients. Clinically, there is a lack of devices that can be directly punctured and drained for sinusitis symptoms and can be indwelling.

Contents of the invention

The purpose of this utility model 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, and each puncture requires general anesthesia. Repeated punctures cause damage 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 punctures have the risk of infection, and need to be fixed on the external nose and face. Tape is difficult to fix, which increases the skin damage of patients. There is a lack of clinically available devices that can be directly punctured and drained for sinusitis symptoms and can be placed in place. Sinus drainage indwelling device.

The utility model is composed of an indwelling tube and a puncture needle, and the puncture needle is arranged in the indwelling tube and passes through the indwelling tube;

The indwelling tube includes a cannula, an air bag, an inflation tube, a first one-way valve, a flushing tube and a second one-way valve. The valve is fixed at the rear end of the inflatable tube, the indwelling tube is a double-chamber structure, the air bag is connected with the inflatable tube, the flushing tube is connected with the cannula, the second one-way valve is fixed at the rear end of the flushing tube, and the back end of the cannula has a plug head;

The front end of the puncture needle has a puncture needle, and the rear end has a handle.

Working principle and process of the utility model:

When in use, the doctor holds the handle and punctures the puncture needle into the nasal cavity of the patient. After reaching the designated position, the puncture needle is pulled out, and the plugs are closed. The first one-way valve and the second one-way valve have elastic plugs respectively to ensure sealing , insert the syringe into the first one-way valve, according to the patient's condition, inject an appropriate amount of air, and then pull out the syringe, because the air bag is connected to the inflatable tube, the air is injected into the air bag through the inflatable tube, and the air bag expands to fix the indwelling tube in the nasal cavity When cleaning or injecting liquid medicine, insert the syringe into the second one-way valve, the flushing tube is connected with the cannula, and the cleaning liquid or medicinal liquid is injected into the nasal cavity through the flushing tube and the cannula. After completion, pull out the syringe After the patient completes the treatment and does not need an indwelling tube, the syringe is inserted into the first one-way valve to extract the air in the air bag.

The beneficial effects of the utility model:

The utility model has the advantages of simple structure, convenient fixing, convenient operation, safety and reliability, can be punctured once and left in the nose for a long time, and can realize the effect of one time punctured indwelling and flushing medicine under local anesthesia, avoiding unnecessary general anesthesia and repeated The harm caused by puncture to patients can reduce the pain of patients, reduce the recovery time of diseases, reduce medical expenses, reduce the risk of surgery, and reduce the risk of infection caused by repeated punctures. It can directly and accurately flush the sinus cavity with drugs, and reduce the need to control inflammation. Systemic medication brings physical discomfort to patients, can reduce the dosage of medication and reduce medical expenses, and is suitable for wide promotion and application.
