Description

Filter for breathing machine

Technical field

This utility model relates to a kind of filter for connecting with respirator, belongs to medical field.

Background technology

Patient is when using assisted mechanical ventilator, the oxygen of respirator output must keep humidity and pressure to be in normal condition, and during conventional ventilator output oxygen, oxygen may contain pathogenic microorganism and impurity, if entering in the patient, easily causing the cross infection of patient and respirator, considerably increasing the probability of nosocomial infection, so respirator needs a defecator, it is the most necessary；

And the filter of traditional structure, the volume of data such as function is more single, is merely capable of simply isolating, such as the filter disclosed in Chinese patent 201420761396.7, it is impossible to while filtering oxygen, the pressure of monitoring oxygen, practicality is the best.

Summary of the invention

The purpose of this utility model is, it is provided that a kind of rational in infrastructure, it is possible to while filtering oxygen, it is ensured that humidity, prevents the filter for breathing machine polluted, to overcome the deficiency of prior art.

This utility model realizes the technical scheme of its purpose:

nullA kind of filter for breathing machine，Including housing，Inlet suction port and air outlet adapter，Air outlet adapter communicates with being difficult to articulate，Housing includes the first housing and the second housing，First housing connects with inlet suction port，Second housing connects with air outlet adapter，First housing and the second housing are screwed connection，The inner chamber of the first housing is installed with activated carbon filter layer，The inwall of the second housing is bonded with liquid storage cotton layer，The tube wall of air outlet adapter connects with being connected ball，In connecting ball, there is tee T，It is respectively supervisor、Exhaustor and humidifier tube，Wherein supervisor connects with air outlet adapter，Exhaustor communicates with the external world，And in the cavity of exhaustor, it is provided with the first check valve，Humidifier tube communicates with humidification box，There is in the cavity of humidification box back-up ring pulverizer plate to be installed in humidification box by back-up ring，Pulverizer plate has some groups of through holes positioned opposite，Humidification box also has the shower nozzle with ft connection.

Having medical pressure sensor on described inlet suction port, air outlet adapter is provided with flow control valve.

The outer wall of described inlet suction port has damping block positioned opposite.

Sealing ring also it is set with on the thread segment that described first housing and the second housing match.

After using said structure, owing to housing includes the first housing and the second housing, the first housing connects with inlet suction port, and the second housing connects with air outlet adapter, first housing and the second housing are screwed connection, such structure just can facilitate the dismounting of housing, not only can open housing at any time, check inner case, simultaneously after using, housing sterilization can also be taken apart and change filter course, while convenient operation, more having saved cost.

And the inner chamber of the first housing is installed with activated carbon filter layer; the inwall of the second housing is bonded with liquid storage cotton layer; so, activated carbon filter layer can filter the oxygen of respirator output, and the patient saliva taken out of and steam between breathing; in reflux course; the liquid storage cotton layer also being able to be stained with by the second inner walls sponges, and will not infiltrate activated carbon filter layer or flow into respirator, both having ensure that filter quality; also protect respirator simultaneously, more prevent the situation of cross infection from occurring.

nullAnd the tube wall of air outlet adapter connects with being connected ball，In connecting ball, there is tee T，It is respectively supervisor、Exhaustor and humidifier tube，Wherein supervisor connects with air outlet adapter，Exhaustor communicates with the external world，And in the cavity of exhaustor, it is provided with the first check valve，Humidifier tube communicates with humidification box，There is in the cavity of humidification box back-up ring pulverizer plate to be installed in humidification box by back-up ring，Pulverizer plate has some groups of through holes positioned opposite，Humidification box also has the shower nozzle with ft connection，This spline structure is advantageous in that，Carbon dioxide and saliva steam that patient discharges between breathing can be discharged as much as possible through exhaustor，Avoid enter into enclosure interior，First check valve ensure that exhaustor can only supplied gas and the discharge of saliva steam simultaneously，And when the humidity of oxygen is required，Liquid can be poured in humidification box，Shower nozzle is connected by outside medical pump，When liquid receives the pressure that shower nozzle applies，Arrival pulverizer plate is，Can pass in through hole，So，Ensure that the humidity of oxygen，And another using method of humidification box is administered exactly，When needs are while patient's oxygen uptake，When the medicine allowing patient suck powder is treated，Medicine powder can be put into humidification box，The outside medical pump of same use connects shower nozzle，Pressure is applied to medicine powder，Through the through hole of pulverizer plate after kicking up，It is made to be atomized as far as possible，Medicine powder just can be inhaled into when patient's oxygen uptake in the lump.

And on described inlet suction port, there is medical pressure sensor, air outlet adapter is provided with flow control valve, and medical pressure sensor can monitor the pressure of respirator output oxygen in real time for medical personnel, during insufficient pressure, medical personnel can know immediately, flow control valve can be the practical situation Flow-rate adjustment to oxygen according to patient in the case of oxygen pressure is normal.

And the outer wall of described inlet suction port has damping block positioned opposite, it is possible to allowing inlet suction port be when breathing circuit connects, plug-in mounting is relatively reliable, is difficult to get loose.
