Abstract
The present invention relates to a multifunctional drainage device for a nose cavity, which comprises a T-shaped three-way pipe. The present invention is characterized in that the T-shaped three-way pipe has a double-layer structure formed by an inner sleeve pipe and an outer sleeve pipe, wherein gaps for putting medicines are formed between the inner sleeve pipe and the outer sleeve pipe, and the inner sleeve pipe is a sieve-shaped multihole pipe which can slowly release the medicines. The present invention has the characteristic that while the multifunctional drainage device for a nose cavity performs support and automatic drainage action, automatic administration after an operation is also realized. After the drainage device is used, drainage after a nasal endoscope operation is smooth. The present invention is favorable for restoring a mucosa function, preventing sinus ostium block and middle turbinate adhesion, and maintaining the normal physiological structure of the nasal cavity. Disease recurrence and the occurrence of complicating diseases are avoided, patients' pain is reduced, a follow-up period is shortened, and the cure rate of operations is improved.
Description
Technical field the present invention relates to a kind of medical apparatus and instruments, the multi-functional drainage apparatus of particularly a kind of nasal cavity.
The background technology nasal endoscopic surgery China carried out ten surplus year, it not only has the little characteristics of surgical wound surface, and can also realize recovering the nasal cavity 26S Proteasome Structure and Function.But this operation must be implemented treatment measures such as drain, administration after surgery, promptly regularly or aperiodically carry out endoscope in more than a year time after surgery with examining, remove chamber crust and newborn polyp, utilize negative pressure drainage device and special syringe to carry out drain and administration simultaneously.The problem that above-mentioned treatment measure exists is: repetitiousness cleaning nasal cavity, can increase the nasal membrane wound, delay wound healing, can't accomplish continuously instant drain and administration, therapeutic process also depends on clinician's medical level and patient's cooperate degree, and these factors all will influence cure rate.
It is the nose T shape silica gel tube of ZL 00 2 12274.X that China's utility model patent provides a kind of patent No., this pipe is placed on middle nasal meatus after nasal endoscopic surgery is finished, playing support middle nasal concha and expansion apertura maxillaris, when preventing nasal sinuses mouth obturation and the effect of nasal cavity structure cohesion, play the effect of adequate drainage, air-flow.
The multi-functional drainage device of nasal cavity that summary of the invention the object of the present invention is to provide the gentle slow release of a kind of energy automatic jet to put medicine.
The object of the present invention is achieved like this: the multi-functional drainage device of a kind of nasal cavity, comprise T tube, it is characterized in that described T tube is the double-decker that is made of inside and outside sleeve pipe, the gap of placing medicine is arranged between inside and outside sleeve pipe, and inner sleeve is for can slowly discharging the sieve shape antipriming pipe of medicine.Described T tube, the cross section of its horizontal inner sleeve is greater than vertical inner sleeve.Be provided with the annular shutoff of the gap sealing that inside and outside sleeve pipe is formed at a horizontal telescopic end.Laterally the internal diameter of inner sleeve with intersection's reducing of vertical inner sleeve, its internal diameter diminishes.Laterally the section ratio at inner sleeve reducing position and other position is 0.4-0.6: 1.
The multi-functional drainage device of nasal cavity is according to the two-phase fluid principle of dynamics, design in conjunction with gas flow characteristic in human nasal cavity configuration and the respiratory, T tube is embedded in middle nasal meatus's nasal sinuses mouth place, laterally sleeve pipe is parallel with middle nasal concha, when realizing supporting role, utilize the respiratory air flow of human body, drive the drug flow be positioned at interlayer, distribute, realization is to the automatic chemical feeding and the automatic jet at middle nasal meatus, middle nasal concha, maxillary sinus position.
Characteristics of the present invention are: the multi-functional drainage device of nasal cavity also realizes the automatic chemical feeding of postoperative when playing support and automatic jet effect.After using this drainage device, make that drain is unobstructed behind the nasal endoscopic surgery, help recovering mucosal function, prevent the hole mouth inaccessible with the middle nasal concha adhesion, keep nasal cavity normal physiological structure, avoid the appearance of palindromia and complication, reduce the patient suffering, shorten, improve the surgical healing rate with the cycle of examining.
Description of drawings Fig. 1 is a structural representation of the present invention.
The specific embodiment is described further below in conjunction with accompanying drawing:
As shown in Figure 1, the T tube of the multi-functional drainage device of nasal cavity is a bilayer sleeve, and the gap that forms between inside and outside sleeve pipe 2,1 is used to place medicine 4, and inner sleeve is sieve shape antipriming pipe.Laterally the cross section of the promptly main respiration channel 5 of inner sleeve is a drainage channel 6 greater than vertical inner sleeve, laterally the internal diameter of inner sleeve with vertical inner sleeve intersection reducing, the reducing position is 0.55: 1 with the cross section ratio at other position in this programme, the secretions that adopts said structure can impel postoperative maxillary sinus etc. to locate prolongs vertical duct and flows into transverse pipe, thereby realizes automatic jet.Be provided with the annular shutoff 3 of the gap sealing that inside and outside sleeve pipe is formed at a horizontal telescopic end.The multi-functional drainage device of nasal cavity can be divided large, medium and small three kinds of size models, adopts medical silica-gel injection molded.
Claims (5)
1, the multi-functional drainage device of a kind of nasal cavity, comprise T tube, it is characterized in that described T tube is the double-decker that is made of inside and outside sleeve pipe, the gap of placing medicine is arranged between inside and outside sleeve pipe, inner sleeve is for can slowly discharging the sieve shape antipriming pipe of medicine.
2, the multi-functional drainage device of nasal cavity according to claim 1 is characterized in that described T tube, and the cross section of its horizontal inner sleeve is greater than vertical inner sleeve.
3, according to the multi-functional drainage device of the described nasal cavity of claim 1, the internal diameter that it is characterized in that horizontal inner sleeve with intersection's reducing of vertical inner sleeve, its internal diameter diminishes.
4,, it is characterized in that being provided with the annular shutoff of the gap sealing that inside and outside sleeve pipe is formed at a horizontal telescopic end according to the multi-functional drainage device of the described nasal cavity of claim 1.
5, according to the multi-functional drainage device of the described nasal cavity of claim 3, the section ratio that it is characterized in that horizontal inner sleeve reducing position and other position is 0.4-0.6: 1.
