Abstract
The utility model relates to a disposable heat and humidity exchanger comprising a tubular shell. Corrugated paper filter elements are arranged in the two ends of the tubular shell respectively, end covers covering the corrugated paper filter elements are arranged at the two ends of the tubular shell, an air hole is formed in each end cover, an oxygen channel is formed in the outer side wall of the tubular shell and is communicated with the two ends of the tubular shell, an oxygen inlet is arranged in the end cover on one side, a universal connecting port and a sputum suction connecting port are further arranged in the tubular shell, and a cover is arranged on the sputum suction connecting port. The disposable heat and humidity exchanger can be installed on a trachea cannula directly, simulates the functions of the nose, and collects and keeps heat and steam in exhaled air. When inspiration is carried out, air in a tepid and humidified state is brought into the airway, and the effect that the airway is humidified effectively and appropriately is achieved. When sputum exists in the trachea cannula, the disposable heat and humidity exchanger can be further directly inserted for sputum suction and connected with oxygen, and the concentration of the oxygen inspired by a patient is improved.
Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, particularly the hot Wet exchanger of a kind of disposable use.
Background technology
For serious symptom and anesthesia patient mechanical respiration, perhaps tracheotomy patients need be set up the artificial airway clinically.Because just often nose, pharyngeal cavity, respiratory tract have the gentle humidifying effect that adds to sucking gas, after the artificial airway sets up, suck gas and got around nasal cavity and the upper respiratory tract with warm and moistening function, must all add gentle humidifying by trachea and following respiratory tract thereof, moisture loses so increases in the respiratory secretions, cause the respiratory mucosa drying, cause the mucociliary system damage, its ability of removing foreign body is lowered greatly; Cause respiratory inflammation, can make respiratory mucosa erosion, ulcer, cause bacterial infection, therefore need in the artificial airway, add hot Wet exchanger, normally bring into play with cilium and the body of gland function of protection respiratory mucosa.
Summary of the invention
Technical problem to be solved in the utility model is at the deficiencies in the prior art, provides a kind of reasonable in design, easy to use, the hot Wet exchanger of disposable use that heating and moistening is effective.
Technical problem to be solved in the utility model is to realize by following technical scheme, this utility model is the hot Wet exchanger of a kind of disposable use, be characterized in: comprise tubular shell, be respectively equipped with the corrugated paper filter element in the two ends of tubular shell, the tubular shell both ends are provided with the end cap that covers the corrugated paper filter element, described end cap is provided with pore, is provided with the oxygen channel that the tubular shell two ends are communicated with in the tubular shell lateral wall, is provided with the oxygen air inlet at a side end cap; Also be provided with general-purpose interface on the tubular shell and inhale the expectorant interface, inhale the expectorant interface and be provided with lid, the end face of lid is made up of some fan-shaped soft catch.
Technical problem to be solved in the utility model can also further realize that the inboard of general-purpose interface is provided with the corrugated paper filter element catch that extends internally by following technical scheme.
This utility model can be directly installed on the tracheal intubation, and the function of simulation nose is collected the heat in the breath and aqueous vapor and remain, and gas is brought in the air flue with state warm, humidifying when air-breathing, guarantees that air flue obtains effective, suitable humidifying; When in the tracheal intubation expectorant being arranged, can also directly insert and inhale expectorant, and can also connect oxygen, improve the concentration of patient's oxygen intake.
This utility model volume is little, and the patient stands up to be difficult for taking off and mourns, and aeration and aeration resistance meet the requirement of human respiratory tract's physiological fully, have also reduced medical personnel's workload.
Compared with prior art, it is simple to operate, easy to use, can improve pulmonary function, can also avoid dirts such as airborne dust, mushroom, suck the situation that easily causes postoperative infection in the lung and take place, can alleviate patient's misery greatly, and its processing technology is simple, cost is low, social benefit and remarkable in economical benefits.
Description of drawings
Fig. 1 is a kind of structural representation of the present utility model.
Fig. 2 is the cross-sectional view of looking up of Fig. 1.
The specific embodiment
Following with reference to accompanying drawing, further describe concrete technical scheme of the present utility model, so that those skilled in the art understands the present invention further, and do not constitute the restriction to its right.
See figures.1.and.2, the hot Wet exchanger of a kind of disposable use, comprise tubular shell 3, be respectively equipped with corrugated paper filter element 5 in the two ends of tubular shell 3, use two corrugated paper filter elements 5 can improve the rejection rate of air, improve performance of keeping humidity simultaneously, tubular shell 3 both ends are provided with the end cap 1 that covers corrugated paper filter element 5, described end cap 1 is provided with pore, be provided with the oxygen channel 8 that tubular shell 3 two ends are communicated with in tubular shell 3 lateral walls, be provided with oxygen air inlet 4 at a side end cap 1, after inserting oxygen, oxygen can enter tracheal casing pipe from the corrugated paper filter element 5 of both sides respectively by oxygen channel 8; Also be provided with the general-purpose interface 2 that cooperates with tracheal intubation on the tubular shell 3 and inhale expectorant interface 6, inhale expectorant interface 6 and be provided with lid 7, the end face of lid 7 is made up of some fan-shaped soft catch, when needing to inhale expectorant like this, lid 7 can be opened sputum aspirator tube can be inserted and inhale expectorant interface 6 enterprising line operates.
During use, directly tracheal intubation is inserted on the general-purpose interface 2 and can uses, when needs are inhaled expectorant, directly pipe can be operated from the lid 7 insertion sputum aspirator tubes of inhaling on the expectorant interface 6, do not inhale expectorant again and do not need the moisture absorption condenser humidifier taken down, use more convenient.When needs connect oxygen, insert by the oxygen air inlet 4 on the end cap 1, can improve concentration of oxygen in the interior gas of patient's suction body.
The inboard of general-purpose interface 2 is provided with corrugated paper filter element 5 catch that extend internally, and carries out spacing can for corrugated paper filter element 5.
