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

Nasal sinuses drain indwelling equipment

Technical field

The present invention relates to a kind of medical instrument, particularly to a kind of nasal sinuses drain indwelling equipment.

Background technology

The inflammation of sinus mucosa, in various sinusitis, maxillary sinusitis is the most common, sinusitis can with single-shot, Can also be multiple, modal pathogenesis is secondary nasal sinuses suppurative inflammation after nasal cavity infects, additionally, Allergy, mechanical obstruction and air pressure change etc. the most easily induce sinusitis, and the infection of tooth can cause tooth source Property maxillary sinusitis, general therapeutic means are that sinusitis puncture and irrigation is treated, existing Clinical practice Nasal sinuses drainage tube is segmental epidural catheter, for silica gel material, needs operative doctor first to do nose in operation Hole punctures, and is then introduced by segmental epidural catheter, increases patient's operation easier, and nasal sinuses drainage tube is difficult to Preserving time, punctures every time and needs general anesthesia, and the injury that patient is caused by repeated localised puncture increases patient suffering, Increasing the recovery time of disease, increase medical expense, improve operation risk, repeated localised puncture has infection wind Danger.Meanwhile, need to fix at external nose and face again, reach the effect of indwelling drain, fixing side Also bring puzzlement in face: 1, anesthetic tube is relatively thin, and adhesive tape sticking is fixing more difficult；2, immobilization with adhesive tape is at external nose And face, increase the risk factor of patient skin damage, increase patient suffering；3, in order to reduce patient's skin Skin damage need to use antibody Monoclonal material adhesive plaster, indirectly increases the hospitalization cost of patient；4, immobilization with adhesive tape is outside Nose and face, as " the tabby cat ", affect patient attractive in appearance.Lacking clinically can be direct for sinusitis symptom Puncture drainage also can be with the device of indwelling.

Summary of the invention

The invention aims to solve above-mentioned existing nasal sinuses drainage tube and be difficult to Preserving time, puncture every time and need Want general anesthesia, the injury that patient is caused by repeated localised puncture, increase patient suffering, increase the recovery time of disease, Increasing medical expense, improve operation risk, repeated localised puncture has infection risk, need to do at external nose and face Fixing, adhesive tape sticking is fixing more difficult, increases patient skin damage, lacks clinically for sinusitis symptom Can Direct perforantes drain with problems such as the devices of indwelling, and a kind of nasal sinuses drain indwelling equipment can be provided.

The present invention is made up of indwelling tube and puncture needle, and puncture needle is arranged in indwelling tube, and through indwelling Pipe；

Indwelling tube includes sleeve pipe, air bag, gas tube, the first check valve, flush pipe and the second check valve, Air bag is arranged on sleeve pipe, and gas tube and flush pipe are fixedly installed on sleeve pipe rear end, and the first check valve is fixed Being arranged on gas tube rear end, indwelling tube is double cavity structure, and air bag is connected with gas tube, flush pipe and set Pipe is connected, and the second check valve is fixedly installed on flush pipe rear end, and sleeve pipe rear end has plug；

Puncture needle front end has piercing needle, and rear end has handle.

The operation principle of the present invention and process:

During use, the hand-held handle of doctor, piercing needle is punctured to patient's nasal cavity, arrives and specify position After, extract puncture needle, plug closes, and the first check valve and the second check valve are respectively provided with elastic plug, Ensure to seal, syringe is inserted in the first check valve, according to patient profiles, squeeze into appropriate air, so After extract syringe because air bag is connected with gas tube, air is injected in air bag by gas tube, gas Capsule expands, and makes indwelling tube be fixed on nasal cavity, when cleaning or inject medicinal liquid, syringe is inserted second In check valve, flush pipe is connected with sleeve pipe, and cleanout fluid or medicinal liquid inject nasal cavity by flush pipe and sleeve pipe In, after completing, extracting syringe, patient completes after treatment need not indwelling tube, syringe insertion Air in first check valve, in extraction air bag.

Beneficial effects of the present invention:

Present configuration is simple, convenient fixing, easy to operate, safe and reliable, can be with one-time puncture length Phase indwelling intranasal, can realize one-time puncture indwelling under local anesthesia and can complete the effect of douche and injection, The injury avoiding non-essential general anesthesia and repeated localised puncture to cause patient, alleviates patient suffering, reduces disease Recovery time, reduce medical expense, reduce operation risk, reduce the infection risk that brings of repeated localised puncture, Can carry out drug irrigation sinus cavities directly and accurately, reduce need because needing to control inflammation systemic administration to patient Bring the discomfort on health, and dosage can be reduced, reduce medical expense, be suitable for widely promote and Application.
