Description

Microorganism arresting system

Technical Field

The invention relates to a medical apparatus, in particular to a microorganism stopping system.

Background

Infectious diseases of the respiratory system afflict human beings for thousands of years, and the blocking device for virus discharged by the patients is only a mask, and worse, the surgical mask is used by most patients, but the mask cannot block the virus. Since patients with respiratory tract infections have poor breathing functions, the N95 mask having a better blocking ability cannot be used, and since the mask causes oxygen deficiency or the original oxygen deficiency is aggravated, only the surgical mask can be used. The initiation of infection is a probable event once insufficient personal protective equipment or protective oversight occurs. However, in the prior art, no microorganism discharge blocking device which is more ideal than a mask exists, so that the mask is still used for blocking the discharge of viruses, and no method is provided. The invention is characterized in that the waste gas exhausted by the patient is pumped out on the premise that the patient does not feel obvious discomfort, and is discharged into the atmosphere after being subjected to harmless treatment by the sterilizing device.

Since the virus volume is much smaller than that of the bacteria, the interception difficulty is much greater, that is, the effective interception technology for the virus is generally effective for the bacteria. Otherwise, it is not necessary. Therefore, the blocking system designed by the inventor aims at the virus as the main object.

The appearance of the multi-channel multifunctional mask is similar to that of an anaesthetic mask and comprises a mask cover and a soft edge, wherein the soft edge is made of a soft material (such as food-grade soft silica gel) with small skin irritation, the mask cover is made of a thin transparent acrylic material, and four groups of 8 pore canals with different sizes are prefabricated on the mask cover: and 2 air inlet holes a02 are formed in the two sides of the upper part of the mask cover, and the air inlet holes extend outwards to form an air inlet valve seat a03 for installing an air inlet check valve. 2 spare air outlet holes a04 on two sides of the lower part of the mask cover extend outwards to form a spare air outlet valve seat a05 for installing a spare air outlet one-way valve. The 1 air outlet hole a14 located right below the face cover extends outwards to form an air outlet pipe seat a11 and a threaded air outlet pipe a12 for connecting with an air pumping one-way through a 27. The apertures of the 2 air inlet holes a02 and the 2 spare air outlet holes a04 are larger and are both 10mm or more, the shapes and diameters of the 4 one-way valve seats are the same, and the positions of the 4 one-way valve seats can be interchanged, that is, the air inlet holes can be arranged at the upper half part and the lower half part of the mask cover freely according to the preference of a user, and conversely, the spare air outlet holes are also the same, and two holes above the mask cover are generally used for air inlet. 3 round holes with smaller diameters are longitudinally arranged and prefabricated in the central part of the mask cover, namely between the 4 air inlet holes and the standby air outlet holes, and are named as an experimental measurement hole a13, a new air inlet hole a09 and an upper oxygen hole respectively. Therefore, the distance of the 3 holes is very close, the hole diameter is the same, and strict distinction in function is not required.

The inner diameters of the air outlet hole and the air outlet pipe are the same, and are respectively larger than or equal to 16mm, so that a user can exhale smoothly (the normal diameter of a common trachea is about 20 mm).

The multifunctional mask accessory comprises: the air inlet one-way valve, the spare air outlet one-way valve, the air outlet filter sheet, the oxygen input short pipe a07, the new air input short pipe a10, the experimental measurement short pipe a06 and the buffer fluid director a 08.

The air inlet one-way valve and the standby air outlet one-way valve have the same structure and different opening pressures, and the opening pressure of the standby air outlet one-way valve is larger than that of the standby air outlet one-way valve. Are respectively arranged on an air inlet valve seat a03 and a spare air outlet valve seat a 05. The outer side of the spare air outlet one-way valve is pre-provided with a filter disc seat for installing an air outlet filter disc, and the air outlet filter disc seat and the air outlet filter disc are combined to be called an air outlet filter one-way valve.

The filter disc seat and the filter disc are of various types and matched with each other. The filter sheet of the present embodiment has a circular shape, and the filter medium in the sheet may be a single type or a composite filter medium in which several materials are stacked, and the filter medium of the present embodiment is a filter medium (melt-blown fabric) for producing an N95 mask.

The opening pressure of the spare air outlet one-way valve is also required to be larger than the opening pressure of the air outlet one-way valve in the air suction one-way straight-through.

The spare air outlet one-way valve does not work normally, and the air exhaled by the user can be discharged through the spare air outlet one-way valve only when the air bag cannot contain redundant air due to excessive air exhaled by the user once or for a plurality of times. The user does not feel the difficulty of air-out.

The air inlet one-way valve and the standby air outlet one-way valve both adopt the unique golden melon type one-way valve.

The appearance of the golden melon type one-way valve is oblate, and the biggest difference between the golden melon type one-way valve and a common circular diaphragm type one-way valve in the current market is the appearance and the movement mode of a diaphragm. The center of a one-way valve membrane in a protective mask on the current market is provided with a hole or a fixing column for fixing the membrane on a valve seat, and the central part of the membrane is fixed during working. The peripheral part of the diaphragm is pressed by airflow to lift and open. The opening pressure and the ventilation area of the check valve depend on the material, the thickness and the diameter of the diaphragm, the opening pressure is mostly determined by the thickness, the diaphragm needs to be thin when the opening pressure is low, and the thin diaphragm is easy to deform after being used for a period of time and is difficult to be closed and reset. The closing body of the golden melon type one-way valve is also a diaphragm, but the opening pressure control parameter is adjusted, and the sealing performance of the diaphragm is kept, so that the opening pressure control parameter is more flexible and more diversified than the current diaphragm one-way valve.

The golden melon type one-way valve is composed of a membrane box, a one-way valve membrane a22, a membrane sliding block a20, a middle shaft a21 and an elastic restorer. The material and the appearance of the one-way valve membrane are similar to those of the commercially available membrane, and a hole is formed in the center of the one-way valve membrane, but the hole is not used for fixing the membrane but is used for embedded connection with the membrane sliding block a 20; the diaphragm sliding block is made of hard plastic, the cross section of the diaphragm sliding block is in an inverted T shape, the lower part of the diaphragm sliding block is in a thin disk shape, the diaphragm sliding block is called a diaphragm sliding block support a23 and used for supporting the one-way valve diaphragm a22, the center of the diaphragm sliding block a20 is in a short pipe shape, the outer diameter of the short pipe is slightly larger than the small hole in the center of the one-way valve diaphragm a22, the small hole in the center of the one-way valve diaphragm a22 is sleeved into the short pipe and cannot slip off, the inner diameter of the short pipe is slightly larger than the outer diameter; the elastic restorer is made of the same material as the one-way valve membrane a22, the shape of the elastic restorer is similar to that of a golden melon, so the name of the golden melon is given, the top of the elastic restorer is an elastic restorer top small disc a25, a small hole is arranged in the center, the diameter of the small hole is slightly smaller than the center axis a21, the bottom of the elastic restorer is generally prefabricated into an elastic restorer bottom small ring a26, a plurality of linear elastic bodies a24 are arranged between the top a25 and the bottom a26, when the elastic restorer top small disc a25 and the elastic restorer bottom small ring a26 approach each other under the external pressure, the elastic bodies a24 protrude outwards to form the shape similar to that of the golden melon, and the bottom structure of the elastic bodies a24 has: the small ring a26 at the bottom of the elastic restorer is prefabricated with the one-way valve membrane a22 into a whole; the two can be separated and only contacted with each other, and are not integrated; the lower end of the elastic body a24 and the one-way valve membrane a22 can be prefabricated into a whole without using a small ring a26 at the bottom of the elastic restorer, and the three structures have advantages and disadvantages in cost, performance and flexibility; the diaphragm box is made of hard plastics, is used for accommodating a one-way valve diaphragm-diaphragm sliding block and an elastic restorer which are completely embedded and connected, is in a hollow oblate shape and consists of a top part and a bottom part a18, the bottom part a18 is provided with a shallow groove which is adaptive to the one-way valve diaphragm a22, the central area of the bottom part a18 is provided with a small shallow groove, the two grooves are connected by ribs, the central groove is adaptive to the bottom part of the diaphragm sliding block a20, the center is provided with a small hole, the diameter of the small hole is slightly smaller than that of a21 of a central axis, the top part of the diaphragm box is in a disc shape, the top part is connected with a18 of the bottom part a by wider ribs, and the center of; the central shaft a21 is a thin hollow metal tube with equal diameter, which is similar to the needle body of the injection needle without joint, and the outer diameter is slightly smaller than the inner diameter of the short tube of the membrane slide block a20 and slightly larger than the small hole in the center of the two ends of the membrane box.

The equipment of above-mentioned gold melon formula check valve: a middle shaft a21 sequentially passes through a small hole in the center of a groove in the central area of a membrane box bottom a18, a membrane slide block a20 short tube-elastic restorer bottom small circular ring a26, an elastic restorer top small wafer a25 central small hole and a membrane box top central small hole, a membrane slide block support a23 is tightly attached to a one-way valve membrane a22 from the bottom surface, and the one-way valve membrane a22 is integrally arranged in the groove of a one-way valve membrane seat a 19. The small disc a25 at the top of the elastic restorer after the assembly is finished is contacted with the top of the diaphragm box, and the movement is limited; the central axis a21 is fixed by the small holes at the top and bottom of the diaphragm capsule and can not move. The elastic body a24 of the assembled one-way valve is in a shape of a golden melon and protrudes outwards, and the membrane slide block a20 can move smoothly along the central axis a21, so that the membrane a22 of the one-way valve is driven to move, and the one-way valve is opened and closed accordingly.

The working principle of the check valve is as follows: when the air flow presses the one-way valve membrane a22 from the bottom of the membrane box, the one-way valve is opened, and the opening modes of the membrane are three types according to the pressed condition, namely the membrane edge is lifted, the whole membrane moves upwards along the central shaft, or the two types are both provided.

The above-mentioned pumpkin type check valve's characteristics: the opening pressure can be preset with high precision and used for a long time. Besides the same opening pressure preset parameter as the existing diaphragm type one-way valve, the opening pressure preset parameter of the golden melon type one-way valve also has other adjustable preset parameters: the number, the diameter, the material and the outward protrusion degree of the elastic body a24 and the diameter of the small ring a26 at the bottom of the elastic restorer can change the opening pressure of the one-way valve. When a large flow of gas passes through the existing check valve, the elastic diaphragm can greatly deform to increase the air flow passing space, and the sealing performance of the check valve can be reduced in the past. The golden melon formula check valve is when large-traffic gas passes through, except the diaphragm elastic deformation of certain degree, mainly enlarges the air current and passes through the space by the whole lifting displacement of diaphragm, and the diaphragm deformation range is very little, and elastic restorer is great to the area of exerting pressure of diaphragm in addition, and the difficult diaphragm that appears warp. Therefore, the golden melon type one-way valve is characterized by low opening pressure, high circulation and high reliability.

The elastic restorer can also be replaced by a superfine pressure spring, preferably a pagoda-shaped pressure spring.

The outer pipe walls of the oxygen input short pipe a07, the new air input short pipe a10 and the experimental measurement short pipe a06 are preformed with threads, and an upper oxygen hole, a new air input hole a09 and an experimental measurement hole a13 are respectively inserted from the inner side of the mask cover. Therefore, the distance of the 3 holes is very close, the hole diameter is the same, and strict distinction in function is not required. After insertion, the mask cover is secured on the outside by a nut. The oxygen input short pipe a07 and the new air input short pipe a10 are respectively connected with hoses for inputting gas corresponding to names, and then corresponding functions can be executed. The laboratory measuring stub a06 is used to measure the pressure within the mask or the composition of the air within the mask, and the laboratory measuring stub a06 is useless and can be closed for the average user.

One end of the oxygen input short pipe a07 and one end of the fresh air input short pipe a10 are prefabricated with a buffering fluid director a08, and the buffering fluid director a08 is used for buffering oxygen and fresh air with larger flow rate input into the mask, so that discomfort caused by the fact that the two gases directly impact the facial skin of a user is avoided. The material of the buffer fluid director a08 is the same as the two short pipes, and is composed of a flow guiding plate a15 and a supporting rib a17, the surface of the flow guiding plate a15 is slightly concave and is matched with the inner surface of the mask cover, the supporting rib a17 is used for connecting the flow guiding plate a15 with the inner opening of the short pipe, a plurality of small holes called air holes a16 are prefabricated on the flow guiding plate a15, when the input air impacts the flow guiding plate a15, one part of the input air can be broken into small strands and flows out from the air holes a16, the other part of the input air flows pass through the supporting ribs a17 and is dispersed along the inner side of the mask cover, and the pressure of the air flows.

The suction one-way through a27 main body is generally in a round tube shape, an air outlet one-way valve is preset at the upper part in the tube cavity, and the embodiment selects and uses a reverse duckbill one-way valve a31 described in another patent 201510120553.5 of the inventor, and the one-way valve is installed on a reverse duckbill one-way valve seat a32 and can be replaced quickly. The inverted duck bill check valve seat a32 is located in the center of the tube, or can be installed on one side of the tube, the top end of the check valve extends in a funnel shape to the periphery to form a thin plate, which is integrated with the inner cavity of the tube and is called as a closed body a29, the thin plate closes the tube cavity except the inlet of the check valve, and the gas from the gas outlet pipe a12 can only flow downwards through the check valve and can not flow backwards. A transverse short pipe, called an air suction pipe a30, is prefabricated at the position above the round pipe, and the inner diameter of the transverse short pipe is the same as or slightly larger than that of an air inlet pipe of a negative pressure source. If the check valve is disposed at the center of the circular tube, the preliminary position of the suction pipe a30 is not required, and if the check valve is disposed at one side of the circular tube, the suction pipe a30 must be preliminary formed at the opposite position thereof. The upper end surface of the round tube extends to the periphery to form a platform shape, the diameter of the platform is the same as the outer diameter of the air outlet pipe a12 on the mask cover, a loose joint a28 is prefabricated between the platform and the air exhaust pipe a30 and used for connecting the air exhaust unidirectional straight-through a27 with the air outlet pipe a12 on the mask cover, and the connecting surface is provided with a soft rubber ring for sealing.

The gas storage bag is made of plastic, latex or silica gel with a very thin bag wall, can be in a three-dimensional shape, is similar to a medical anesthesia air bag, and can also be in a flat shape, and is similar to a simple respirator gas storage bag for emergency treatment. The inner diameter of the air inlet of the air storage bag is the same as the lower end of the air pumping one-way through a 27.

The circuit type adjusting device controls the working condition of the machine by adjusting the voltage or frequency conversion supplied to the micro air source, thereby adjusting the amount of gas sucked by the negative pressure source, and the adjusting mode is commonly used on the oxygen supply device of the aquarium; the air path type adjusting device changes the negative pressure value in the air path by adjusting a shunt valve preset on the suction air path, thereby adjusting the amount of air sucked by a negative pressure source. The two air flow adjusting modes have the advantages and the disadvantages, can be used independently or jointly, and can be used for more accurately adjusting the amount of air sucked by the negative pressure source.

The positive pressure source uses a micro air pump or a micro turbine fan, and the power of the positive pressure source is smaller than that of the like machine used by the negative pressure source. The air outlet end of the air inlet pipe is connected with a new air input pipe a10 on the mask cover through a hose, and is used for providing new air for a user, wherein the new air is filtered and contains a large amount of negative ions relative to the air inhaled by the user.

The flow divider can regulate the pressure and flow of the air flow in the whole positive pressure pipeline although being installed on the main pipeline. When the pressure relief shunting function is closed, the gas output by the positive pressure source machine is completely sent to a patient for use, and when the pressure relief shunting function is opened, part of the gas output by the positive pressure source machine can be discharged into the case, so that the gas quantity supplied to the patient is reduced. Normally, the pressure relief function of the diverter valve is closed and the patient is provided with full gas output from the positive pressure source.

The branch pipeline of the air exhaust is connected with a pressure relief valve, and when the pressure in the positive pressure pipeline reaches a preset value, the pressure relief valve is opened to protect a positive pressure source machine; the branch pipeline II is connected with the measuring end of the pressure sensor; and the third branch pipeline is connected with a miniature ball valve, the airflow output end of the miniature ball valve is connected with an airflow input short pipe a34 of the flavor inhaler, the airflow output short pipe a39 of the flavor inhaler is connected with a three-way pipe connected to the main pipeline through a hose, the branch gas returns to the main pipeline, and the miniature ball valve adjusts the valve core passage area so as to adjust the gas quantity passing through the branch gas path.
