Abstract

The utility model belongs to the field of medical instruments, and particularly relates to a disposable artificial nose. The disposable artificial nose comprises a shell cover and a shell body, wherein the upper end surface of the shell cover is of an air-permeable structure, one end of the shell cover is connected with the shell body, a buckle is arranged at the other end of the shell cover and is buckled with a clamping groove formed in the shell body, a conversion connector is connected to the lower end of the shell body in an inserting mode, the shell cover is provided with an oxygen connecting port, a buckling belt with a sealing cap is further arranged at the outer side of the shell cover, an inner pipe I is arranged inside the shell cover, a supporting frame and an inner pipe II are arranged inside the shell body, and a heat and humidity exchange medium and an air filtering film are further arranged inside an inner cavity of the shell body. The disposable artificial nose is reasonable in structure, comprehensive in function, simple to manufacture, and capable of being directly installed on a trachea cannula, thereby achieving the function of heat and humidity exchange. The air filtering film can prevent particles and dust in the external environment from entering the trachea, and reduces generation of sputum. A sputum suction catheter can be inserted into the disposable artificial nose to suck sputum, and the disposable artificial nose is sealed with the sealing cap after finishing sputum suction and is prevented from being polluted by the external environment. When a user needs oxygen therapy, the disposable artificial nose can be connected with oxygen delivery equipment through the oxygen connecting port.

Description

Disposable use artificial nose

Technical field

This utility model belongs to medical instruments field, particularly a kind of disposable use artificial nose.

Background technology

Clinically; for the wet heat exchanger in order to alternative upper respiratory tract function of serious symptom and anaesthesia patient mechanical respiration or a kind of manual manufacture of tracheotomy patients needs; the artificial nose of namely often saying; it can simulate the function of part nose; heat in breath and aqueous vapor are collected and remained; when air-breathing, gas is through artificial nose; bring in air flue with state warm, humidifying; guarantee that air flue obtains effective, suitable humidifying; cilium and Intervention with protection respiratory mucosa are normally brought into play, and prevent from causing the relevant symptoms such as respiratory inflammation.

In actual applications, more existing artificial noses can realize the wet function of exchange of heat, but microgranule, dust in can not blocks air enter in the middle of trachea, on general microgranule, dust, be all attached with bacterial virus, and the invasion of bacterial virus can cause patient's sputum to increase, bring misery to patient, bring burden to medical personnel; The more existing artificial nose that possesses suction sputum function, suction sputum passage does not have seal protection, easily causes extraneous pollution yet, brings unnecessary hidden danger to patient.

Summary of the invention

This utility model, in order to make up the deficiency of existing design, provides a kind of disposable use artificial nose.

This utility model solves the technical scheme that its technical problem adopts: disposable use artificial nose, comprise cap, housing, described cap upper surface is ventilating structure, cap one end is connected with housing, the cap other end is provided with buckle and is interlockingly connected with the draw-in groove being located on housing, is plugged with adapter in housing lower end; On cap, be provided with oxygen interface, cap outside is also provided with the cingulum with sealing cap, is provided with inner tube I in the inside of cap; Be provided with support and inner tube II in enclosure interior, be also provided with the wet exchange media of heat and air-filtering membrane at housing inner chamber.

Described air-filtering membrane is hydrophobicity filter membrane, and pore size filter, between 0.2 μ m～0.5 μ m, can reach 98% to microgranule rejection rate more than 0.3 μ m in air; The center of air-filtering membrane is provided with circular hole and is socketed in inner tube II outside.

The wet exchange media of described heat is wood pulp cellulose material, curling forming after compacting texture; The wet exchange media of heat is socketed in inner tube II outside and between air-filtering membrane and support, this frame mode not only can increase Air permenbility, and the wet exchange area of heat is large, guarantees the effect of the wet exchange of heat.

Described sealing cap can be fastened on the upper port of inner tube I, while needing suction sputum, opens sealing cap, after suction sputum finishes, buckles sealing cap, and protection suction sputum passage prevents extraneous pollution.

Beneficial effect: this utility model is rational in infrastructure, complete function, makes simply, can be directly installed in tracheal intubation, realizes the function of the wet exchange of heat; Air-filtering membrane can stop that microgranule, the dust in external environment condition enters trachea, reduced the generation of expectorant; Can insert sputum aspirator tube and carry out suction sputum, suction sputum is complete with sealing cap sealing, prevents external environment condition pollution; Need to cure by oxygen therapy time, can connect oxygen delivery equipment by oxygen interface; Be provided with adapter, be convenient for changing device.

The specific embodiment

With reference to Figure of description, this utility model is described in detail below:

Referring to figs. 1 to Fig. 4, this disposable use artificial nose, comprises cap 1, housing 2, described cap 1 upper surface is ventilating structure, cap 1 one end is connected with housing 2, and cap 1 other end is provided with buckle 15 and is interlockingly connected with the draw-in groove 23 being located on housing 2, is plugged with adapter 5 in housing 2 lower ends; On cap 1, be provided with oxygen interface 11, cap 1 outside is also provided with the cingulum 14 with sealing cap 13, is provided with inner tube I 12 in the inside of cap 1, and sealing cap 13 can be fastened on the upper port of inner tube I; Be provided with support 21 and inner tube II 22 in housing 2 inside, when cap 1 and housing 2 are interlockingly connected, the inner tube I 12 that it is inner and inner tube II 22 interfaces are meshed, form the passage that sputum aspirator tube inserts, also be provided with the wet exchange media 4 of heat and air-filtering membrane 3 at housing 2 inner chambers, the wet exchange media 4 of heat is socketed in inner tube II 22 outsides and between air-filtering membrane 3 and support 21, air-filtering membrane 3 inner sides are socketed in inner tube II 22 outsides, air-filtering membrane 3 outsides and housing 2 medial wall laminatings, entering of the microgranule in blocks air, dust to greatest extent.In process of production, because cap 1 adopts manner to be connected with housing 2, easy to assembly quick, production efficiency is high.

When use, be connected in tracheal intubation by adapter 5, while needing suction sputum, open sealing cap 13, insert sputum aspirator tube, suction sputum is complete, buckles sealing cap 13, and because sealing cap 13 is located on cingulum 14, can not lose and drop, and also easy to operate; Need to cure by oxygen therapy time, connect oxygen delivery equipment with oxygen interface 11; Need to change this disposable use artificial nose, screw off from adapter 5, change.
