Description
Technical field
This utility model relates to medical apparatus, especially a kind of wet heat exchanger.
Background technology
Wet heat exchanger (HME) is also known as artificial nose, it can simulate the function of nose, and the heat in breath and aqueous vapor collected and remain, during air-breathing, gas is through artificial nose, bring in air flue with state that is warm, humidifying, ensure that air flue obtains effective, suitable humidifying; Meanwhile, it to external world dust and pathogenic bacteria have certain filtration, can effectively stop extraneous foreign body enter trachea so that reduce because of foreign substance pollution, improve safety.
Artificial nose can simulate human dissection humidification system to a certain extent, has heating and moistening filter virus and stops that extraneous foreign body enters the effect of trachea, reduce incidence of pulmonary infection.Because artificial nose does not provide extra heat and moisture, cause ischesis person's poor effect for dehydration, low temperature or Pulmonary Diseases, some patients still needs timely liquid make-up to enter amount.Whether use artificial nose patient is also needed to carry out extra humidifying, or utilizes which kind of humidifying to need to be studied further.Because artificial nose can not be reused, also cause medical expense to rise, making patients's financial burden, await developing clinical novel sterilization and also can reuse and the best temperature removing dampness filters of energy monitor temperature, humidity.
Because wet heat exchanger is disposable equipment, its cost costly at the same time, increased the weight of the financial burden of patient, reduced the popularity rate of wet heat exchanger.Whether in addition, present wet heat exchanger lacks examination tube sealing function, and tracheotomy patients usually needs tentative plugging before tube drawing, transition can breathe for mouth and nose, get rid of air pipe sleeve smoothly to observe patient.
Utility model content
The purpose of this utility model is to provide that a kind of structure is simple, and simple installation, has tube sealing function, simultaneously can the wet heat exchanger of more renew cartridge.
For achieving the above object, the technical scheme that this utility model adopts is: a kind of wet heat exchanger, comprising: housing, lid, is characterized in that: overall through and be divided into upper and lower two parts at described housing, top is filter chamber, bottom is air flue, in described filter chamber, be provided with filter element; Described lid is provided with air passing hole, and this air passing hole is corresponding with filter element; Air flue is also provided with and leads expectorant hole.
Preferably, described lid is also provided with spiral cover, this spiral cover is rotated by knob and lid and is socketed, and spiral cover is corresponding with air passing hole position.
Preferably, described air passing hole is scallop hole, and the axle center of air passing hole, lid and spiral cover three overlaps.
Preferably, cylindrically, the filter element corresponding with filter chamber shape fills up filter chamber to described filter chamber.
Preferably, described filter element is hydrophilic material.
Preferably, described filter chamber diameter of section is less than airway cross-section diameter.
Preferably, described expectorant hole of leading is extended at air flue wall portion fork shape, and this is led expectorant hole and is positioned at below filter chamber, and its end is provided with seal cover, sealing lid with lead expectorant hole and be threaded connection.
After this utility model adopts said structure, by adopting detaching filter element, adjusting air passing hole and increasing the version of sputum suction hole, achieve the Recycling of wet heat exchanger, the filter element changed at any time ensure that patients with respiratory tract is not infected, make housing realize Recycling to shell sterilization, thus save medical treatment cost.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, this utility model is described in further detail:
As shown in the figure, for achieving the above object, the technical scheme that this utility model adopts is: a kind of wet heat exchanger, comprise: housing 1, lid 2, is characterized in that: overall through and be divided into upper and lower two parts at described housing 1, top is filter chamber 11, bottom is air flue 12, in described filter chamber 11, be provided with filter element 3; Described lid 2 is provided with air passing hole 21, and this air passing hole 21 is corresponding with filter element 3; Air flue 12 is also provided with and leads expectorant hole 13.
Preferably, described lid 2 is also provided with spiral cover 4, this spiral cover 4 is rotated by knob 5 and lid 2 and is socketed, and spiral cover 4 is corresponding with air passing hole 21 position.
Preferably, described air passing hole 21 is scallop hole, and the axle center of air passing hole 21, lid 2 and spiral cover 4 three overlaps.
Preferably, cylindrically, the filter element 3 corresponding with filter chamber 11 shape fills up filter chamber 11 to described filter chamber 11.
Preferably, described filter element 3 is hydrophilic material.
Preferably, described filter chamber 11 diameter of section is less than air flue 12 diameter of section.
Preferably, described expectorant hole 13 of leading is extended at air flue 12 wall portion fork shape, and this is led expectorant hole 13 and is positioned at below filter chamber 11, and its end is provided with seal cover 6, sealing lid 6 with lead expectorant hole 13 and be threaded connection.
Operation principle: wet heat exchanger is connected to conduit mouth after setting up by artificial airway, now, patient respiratory flow is by wet heat exchanger, and when air-flow is by filter chamber 11, the filter element in filter chamber 11 filters air-flow, ensures that patient is not infected.Filter element 3 is by sputum contamination and plugging or after using for a long time, directly can remove lid 2 and change filter element 3 for subsequent use, housing 1 environment better and the not serious patient of pulmonary infection no more than 2 days, otherwise should carry out through clean at 24 hours, after disinfecting, reuse.Expectorant hole 13 of leading on air flue 12 keeps closed state by seal cover 6, when needs carry out suction sputum operation to patient, turns on the seal cover 6 of leading top, expectorant hole 13, by the sputum sucking-off in patient airway.
When patient meets the indication pulling out tracheal casing pipe, following the doctor's advice and give to try tube sealing, by rotating spiral cover 4, regulating the open area of air passing hole 21 on lid 2, to patient's procedure of adaptation, close artificial airway gradually, transition is that mouth and nose are breathed, and pulls out tracheal casing pipe smoothly.
The above is preferred implementation of the present utility model; certainly the interest field of this utility model can not be limited with this; should be understood that; for those skilled in the art; the technical solution of the utility model is modified or equivalent replacement, do not depart from the protection domain of technical solutions of the utility model.
