Description

A microbial blocking system

technical field

Background technique

Infectious diseases of the respiratory system have plagued human beings for thousands of years, and the only blocking device for such patients to discharge viruses is masks. What’s worse, most patients use surgical masks, but such masks cannot block the virus. Because the respiratory function of patients with respiratory infectious diseases is not good, N95 masks with better blocking ability cannot be used, because such masks will cause hypoxia or aggravate the original hypoxia, so only surgical masks can be used. Once there is insufficient personal protective equipment or protection omissions, infection is a high probability event. However, in the prior art, there is no microbial discharge blocking device that is more ideal than masks. The reason why masks are still used to block the discharge of viruses is really impossible. In the present invention, under the premise that the patient does not feel obvious discomfort, the exhaust gas exhaled by the patient is drawn out, and after being harmlessly treated by the sterilizing device, it is discharged into the atmosphere. dramatically decrease.

Detailed ways

The present invention will be further described below with reference to the accompanying drawings:

The present invention is composed of the following parts: multi-channel multi-function mask, multi-function mask accessories, one-way straight-through air extraction, storage bag, negative pressure source and negative pressure air flow regulating device, positive pressure source and positive pressure air flow regulating device, pressure relief Valve, pressure sensor kit, negative ion generator module, odorizer, battery, AC to DC module, microbial interception component, control circuit board, chassis.

The appearance of the above-mentioned multi-channel multi-function mask is similar to that of anesthesia masks. It consists of a mask cover and a soft edge. Made of transparent acrylic material, the cover is prefabricated with four groups of 8 holes of different sizes: 2 air intake holes a02 located on both sides of the upper part of the mask cover, the air intake holes extend outward into the intake valve seat a03 for Install the intake check valve. The two spare air outlet holes a04 located on both sides of the lower part of the mask cover extend outward to form the spare air outlet valve seat a05, which is used to install the spare air outlet check valve. An air outlet hole a14 located just below the mask cover extends outward into an air outlet pipe seat a11 and a threaded air outlet pipe a12, which are used to connect with the one-way air extraction a27 described below. The above-mentioned 2 air inlet holes a02 and the 2 spare air outlet holes a04 have larger diameters, both of which are 10mm or more. The above-mentioned 4 one-way valve seats have the same shape and diameter, and their positions can be interchanged, that is, the air inlet holes It can be set freely on the upper or lower half of the mask cover according to the user's preference. On the contrary, the spare air outlet holes are also the same. Usually, the two holes above the mask cover are used for air intake. In the central part of the mask cover, that is, between the above-mentioned 4 air inlet holes and the spare air outlet holes, 3 circular holes with smaller diameters are prefabricated longitudinally arranged, named as the experimental measurement hole a13, the new air input hole a09, the upper Oxygen hole. Because the distance between the three holes is very close and the hole diameter is the same, there is no need to strictly distinguish the function.

The inner diameter of the above-mentioned air outlet is the same as that of the air outlet, and both must be greater than or equal to 16mm, so that the user can exhale smoothly (the normal diameter of an ordinary trachea is about 20mm).

The accessories of the above-mentioned multi-function mask include: inlet check valve, spare outlet check valve, outlet filter, oxygen input short pipe a07, new air input short pipe a10, experimental measurement short pipe a06, buffer guide a08.

The above inlet check valve and the backup outlet check valve have the same structure but different opening pressures, the latter being greater than the former. They are respectively installed on the intake valve seat a03 and the spare outlet valve seat a05. The outer side of the spare outlet check valve is prefabricated with a filter seat, which is used to install the outlet filter, and the two are collectively called the outlet filter check valve.

The above-mentioned filter holder and filter have various types, which are matched with each other. The shape of the filter sheet in this embodiment is circular, and the filter material in the sheet can be a single type or a composite filter material formed by superimposing several materials. The filter material in this embodiment is a filter material for making N95 masks (melting spray cloth).

The opening pressure of the backup outlet check valve must also be greater than the opening pressure of the outlet check valve in the following exhaust check.

The above-mentioned spare air outlet check valve generally does not work. Only when the user exhales too much one or several times and the airbag cannot hold the excess gas, the user's exhaled air can be discharged through the spare air outlet check valve. The user does not experience difficulty in exhaling.

The above-mentioned inlet check valve and backup outlet check valve all adopt the unique pumpkin-type check valve of the present invention.

The appearance of the above-mentioned pumpkin check valve is oblate, and the biggest difference between the round diaphragm check valve and the common circular diaphragm check valve in the current market is the shape and movement mode of the diaphragm. At present, the one-way valve diaphragm in the protective mask on the market has a hole or a fixed column in the center, which is used to fix the diaphragm on the valve seat, and the central part of the diaphragm does not move during operation. The peripheral part of the diaphragm is lifted by the top pressure of the airflow - open. The opening pressure and ventilation area of this one-way valve depend on the material, thickness and diameter of the diaphragm. The opening pressure is mostly determined by the thickness. If the opening pressure is to be low, the diaphragm must be made very thin. It is easy to deform after time, and it is difficult to close and reset. The closure body of the gourd check valve is also a diaphragm, but it is far more flexible and diverse than the current diaphragm check valve in terms of adjusting the opening pressure control parameters and maintaining the tightness of the diaphragm.

The above-mentioned pumpkin-type check valve is composed of a diaphragm box, a one-way valve diaphragm a22, a diaphragm slider a20, a central axis a21, and an elastic reset device. The material and shape of the above-mentioned one-way valve diaphragm are similar to the aforementioned commercially available ready-made diaphragms, and there is also a hole in the center, but this hole is not used for fixing the diaphragm, but for embedded connection with the diaphragm slider a20; The slider is made of hard plastic, with an inverted T-shaped cross section and a thin disc at the bottom, called the diaphragm slider support a23, which is used to support the check valve diaphragm a22, and the center of the diaphragm slider a20. It is in the shape of a short tube. The outer diameter of the short tube is slightly larger than the small hole in the center of the one-way valve diaphragm a22. The outer diameter of a21, the diaphragm slider a20 can slide smoothly along the central axis a21; the elastic reset device is made of the same material as the one-way valve diaphragm a22, and its shape is similar to a pumpkin, so it is named after the pumpkin, and the top of the elastic reset device is a piece of elastic reset The small disc a25 at the top of the device has a small hole in the center, the diameter of which is slightly smaller than the central axis a21, and the bottom is usually prefabricated into a small circular ring a26 at the bottom of the elastic reducer. Between the top a25 and the bottom a26, there are several linear elastic bodies a24, when the small disc a25 at the top of the elastic resetter and the small ring a26 at the bottom of the elastic resetter are close to each other by external pressure, the elastic body a24 protrudes outward to form a shape similar to a gourd. The bottom structure of the elastic body a24 has three forms : The small ring a26 at the bottom of the elastic resetter and the one-way valve diaphragm a22 are prefabricated into one; the two can also be separated and only contact each other, not integrated; the small ring a26 at the bottom of the elastic resetter can also not be used, and the elastic body The lower end of a24 is prefabricated into one piece with the one-way valve diaphragm a22. These three structures have their own advantages and disadvantages in terms of cost, performance and flexibility; the above-mentioned diaphragm box is made of hard plastic and is used to accommodate complete fittings and connections. One-way valve diaphragm-diaphragm slider and elastic resetter, in the form of a hollow oblate, composed of two parts: top and bottom a18, bottom a18 has a shallow groove conforming to the one-way valve diaphragm a22, bottom a18 There is another small shallow groove in the central area of the two grooves. The two grooves are connected by ribs. The central groove is conformal to the bottom of the diaphragm slider a20, and there is a small hole in the center. The diameter is slightly smaller than the central axis a21. The top is in the shape of a disc, the top and bottom a18 are connected by wider ribs, and there is also a small hole in the center of the top whose diameter is smaller than the central axis a21; the central axis a21 is a small equal-diameter hollow metal tube, similar to removing the joint The outer diameter of the injection needle body is slightly smaller than the inner diameter of the short tube a20 of the diaphragm slider, and slightly larger than the small hole in the center of the two ends of the diaphragm box.

The assembly of the above-mentioned pumpkin check valve: pass the central axis a21 through the small hole in the center of the groove in the central area of the diaphragm box bottom a18 in sequence, the short tube of the diaphragm slider a20 - the small ring a26 at the bottom of the elastic resetter, the elastic resetter The center hole of the top small disc a25, the center hole of the top of the diaphragm box, the diaphragm slider support a23 is close to the one-way valve diaphragm a22 from the bottom, and the one-way valve diaphragm a22 is integrally placed on the one-way valve diaphragm seat a19 in the groove. After the assembly is completed, the small disc a25 on the top of the elastic resetter is in contact with the top of the diaphragm box, and the movement is limited; the central axis a21 is fixed by the small holes on the top and bottom of the diaphragm box and cannot move. The elastic body a24 of the assembled one-way valve protrudes outward in the shape of a gourd, and the diaphragm slider a20 can move smoothly along the central axis a21, thereby driving the one-way valve diaphragm a22 to move, and the one-way valve also opens and closes accordingly. closure.

The working principle of the above one-way valve: when the air flow presses the one-way valve diaphragm a22 from the bottom of the diaphragm box, the one-way valve opens. The whole moves up the central axis, or both.

The characteristics of the above-mentioned pumpkin check valve: the opening pressure can be preset with high precision and the reliability of long-term use. The opening pressure preset parameters of the gourd check valve are the same as those of the existing diaphragm check valve, and there are several other adjustable preset parameters: the number, diameter, material of the elastic body a24, outward protrusion degree, the diameter of the small ring a26 at the bottom of the elastic resetter, and the change of each parameter can change the opening pressure of the one-way valve. In the existing one-way valve, when a large flow of gas passes through, the elastic diaphragm will be greatly deformed to increase the air flow passage space, and the tightness performance of the one-way valve will decrease in the long run. In addition to the elastic deformation of the diaphragm to a certain extent, the pumpkin-type one-way valve mainly relies on the overall lifting and displacement of the diaphragm to expand the airflow passing space when the large flow of gas passes through. The deformation of the diaphragm is small, and the elastic reset device The pressure area on the diaphragm is large, and the diaphragm is not easily deformed. Therefore, the pumpkin check valve is characterized by low opening pressure, high fluidity, and high reliability.

The above elastic resetter can also be replaced by a very fine compression spring, preferably a pagoda-shaped compression spring.

The outer wall of the above-mentioned oxygen input short pipe a07, new air input short pipe a10, and experimental measurement short pipe a06 is prefabricated with threads, and the upper oxygen hole, new air input hole a09, and experimental measurement hole a13 are respectively inserted from the inside of the mask cover. Because the distance between the three holes is very close and the hole diameter is the same, there is no need to strictly distinguish the function. Once inserted, secure with a nut on the outside of the mask cover. The oxygen input short pipe a07 and the new air input short pipe a10 are respectively connected to the hoses for inputting the gas corresponding to the name, and the corresponding functions can be performed. The experimental measurement short tube a06 is used to measure the pressure in the above-mentioned mask or the air composition in the mask. For ordinary users, the experimental measurement short tube a06 is useless and can be closed.

One end of the above-mentioned oxygen input short pipe a07 and new air input short pipe a10 is prefabricated with a buffer flow guide a08. The buffer flow guide a08 is used to buffer the oxygen and fresh air with a large flow in the input mask, so as to avoid the direct flow of these two gases. Impacts the user's facial skin, causing discomfort. The material of the buffer deflector a08 is the same as the above two short pipes, and it is composed of a deflector a15 and a supporting rib a17. The baffle a15 and the inner port of the short tube above, the baffle a15 is prefabricated with many small holes called air holes a16. When the input gas hits the baffle a15, part of it will be broken into small strands and come out from the air holes a16. Another part of the airflow passes between the support ribs a17 and spreads out along the inside of the mask cover, and the pressure of the airflow is also buffered.

The above-mentioned oxygen input short pipe a07, new air input short pipe a10, and experimental measurement short pipe a06 can also be prefabricated into one body with the upper oxygen hole, new air input hole a09, and experimental measurement hole a13, respectively, and the cost of this production method is reduced, But there is also less flexibility in airflow configuration.

The main body of the above-mentioned air extraction one-way straight a27 is usually in the shape of a circular tube, and an air outlet one-way valve is preset in the upper part of the tube cavity. The check valve is installed on the reverse duckbill check valve seat a32 and can be replaced quickly. The anti-duck bill one-way valve seat a32 is located in the center of the above-mentioned round pipe, and can also be installed on one side of the round pipe. Body a29, this thin plate closes the circular lumen except the inlet of the one-way valve, forcing the gas from the gas outlet pipe a12 to flow downward only through the one-way valve, and cannot flow back. A short horizontal pipe is prefabricated at the upper position of the round pipe, called the exhaust pipe a30, the inner diameter of which is the same as or slightly larger than the intake pipe of the negative pressure source. If the one-way valve is arranged in the center of the round pipe, there is no requirement for the prefabricated position of the suction pipe a30. If the one-way valve is arranged on one side of the round pipe, the suction pipe a30 must be prefabricated in its opposite position. The upper end of the above-mentioned circular tube extends in a platform shape toward the surroundings, and the diameter of the platform is the same as the outer diameter of the air outlet pipe a12 on the aforementioned mask cover. The straight-through a27 is connected to the air outlet pipe a12 on the mask cover, and there is a soft rubber ring on the connecting surface for sealing.

The above-mentioned storage bag is a plastic, latex or silicone product with a thin wall, and the shape can be a three-dimensional shape, similar to a medical anesthesia bag, or a flat shape, similar to a simple respirator storage bag for first aid. The inner diameter of the air inlet of the storage bag is the same as that of the lower end of the above-mentioned one-way straight a27 for air extraction. When in use, the air inlet of the air storage bag is sleeved at the lower end of the one-way straight a27 for air extraction to store the exhaust gas exhaled by the user.

The above negative pressure source uses a micro air pump or a micro turbine fan, and its air intake end is connected to the chassis air intake short pipe c01 on the surface of the chassis in the chassis. A30 is connected to take out the gas in the storage bag.

The above-mentioned negative pressure source air flow regulating devices are divided into two types according to the different regulating methods and principles: circuit-type regulating devices and air-path regulating devices. The circuit type adjustment device controls the working condition of the machine by adjusting the voltage or frequency conversion of the micro air source, so as to adjust the amount of gas inhaled by the negative pressure source. This adjustment method is commonly used in the oxygen supply device of the aquarium; the air circuit type The adjusting device adjusts the shunt valve preset on the inhalation air path to change the negative pressure value in the air path, thereby adjusting the amount of gas inhaled by the negative pressure source. This air flow adjustment method is widely used in medical suction devices. These two air flow adjustment methods have their own advantages and disadvantages, and can be used alone or in combination to more accurately adjust the amount of gas inhaled by the negative pressure source.

The above positive pressure source uses a micro air pump or a micro turbine fan, and the power is smaller than that of the same name machine used by the aforementioned negative pressure source. Its outlet end is connected to the new air input short tube a10 on the mask cover through a hose, which is used to provide the user with fresh air. Compared with the air inhaled by the user, the new air is filtered and contains a large amount of negative ions. .

The above-mentioned positive pressure air flow regulating device is divided into two types according to the different regulating methods and principles: circuit type regulating device and gas path regulating device, whose principles and components are the same as those of the above negative pressure source air flow regulating device.

The above-mentioned negative ion generator module is miniature and low-power consumption, and the electrode that generates negative ions is installed in the gas path at the far end of the above-mentioned positive pressure source exhaust pipe, and the air path is sealed, and the air output by the positive pressure source machine and the negative ions generated by the above-mentioned electrodes are Mixed to form mixed air, which is delivered into the mask through a hose connected to the new air input short tube a10 on the mask cover.

The above-mentioned positive pressure pipeline is derived from the air outlet of the positive pressure source machine, and is divided into two branches according to the function, the amount of air flow, and the internal resistance of the pipeline: the mainstream pipeline and the branch pipeline.

The airflow output end of the above-mentioned positive pressure source is connected to the main flow end of an air exhaust. This air exhaust has three branch flows. After the other main flow end of the air exhaust is connected to a diverter valve, a tee pipe is connected, and one end of the tee pipe is directly connected to the surface of the chassis. The air outlet short pipe c02 of the case is connected with the other end of the air outlet short pipe a39 of the scent device. Although the above-mentioned diverter valve is installed on the main flow pipeline, it can adjust the airflow pressure and flow rate in the entire positive pressure pipeline. When the pressure relief and shunt function is turned off, all the gas output by the positive pressure source machine is sent to the patient for use. When the pressure relief and shunt function is turned on, part of the gas output by the positive pressure source machine will be discharged into the chassis, reducing the amount of gas supplied to the patient. . Normally, the pressure relief function of the diverter valve is closed, and the patient can obtain all the gas output by the positive pressure source.

The branch pipeline of the air exhaust is connected to a pressure relief valve. When the pressure in the positive pressure pipeline reaches the preset value, the pressure relief valve opens to protect the positive pressure source machine; the branch pipeline is connected to the measuring end of the pressure sensor; the branch pipe Road three is connected to a micro ball valve, the air flow output end of the micro ball valve is connected to the air flow input short pipe a34 of the odorant, and the air output short pipe a39 of the odorant is connected to the three-way pipe connected to the mainstream pipeline through a hose, and the tributary gas returns to the mainstream Pipeline, the above-mentioned micro ball valve adjusts the amount of gas passing through the branch gas path by adjusting the area of the valve core channel.

The above-mentioned differential pressure sensor kit includes a differential pressure sensor, a miniature horn, and a warning light on the surface of the chassis, which is also one of the safety protection measures of the present invention. The measuring end of the sensor is installed in the above-mentioned positive pressure air circuit, and the signal output end is connected to the miniature speaker through the control circuit board. When the internal pressure of the positive pressure air circuit increases, the voltage of the output end of the sensor signal will be triggered to change synchronously, reaching the working voltage of the miniature speaker. , the horn sounds an alarm, and the warning light lights up to remind the user. In order to reduce product cost, differential pressure switch can also be used instead of differential pressure sensor.

The above-mentioned odorant is an odor-dissipating device preset on the above-mentioned branch pipeline, and is made of plastic, acrylic or glass. The shape is cylindrical or rectangular, and the two ends have an airflow input short pipe a34 and an airflow output short pipe a39, which are respectively connected with the corresponding parts of the branch pipeline. The shell a33 and the flavor device core a36 are hollow between the two tubes, which is called the flavor device shell and the drug flavor device core space a37. The flavor device core a36 is also two overlapping tubular structures, which are called the flavor device core outer tube a35 and the drug flavor device core inner tube a38 respectively. Prefabricated with multiple long strip ventilation slots. In the space between the two tubular structures of the odorant core, a medicament core made of a breathable material with strong water absorption (such as a sponge) is preset, which is used to absorb the liquid with medicinal properties or medicinal smell. The airflow input short tube a34 is prefabricated in the center of the top of the flavor device shell a33, and the airflow output short tube a39 is prefabricated in the center of the top end of the flavor device core a36, which is in equal diameter with the inner cavity a38 of the internal tubular structure of the flavor device core a36. The gas from the airflow input short pipe a34 cannot directly reach the airflow output short pipe a39, and must pass through the ventilation groove and the drug core of the medicine core a36 to reach the airflow output short pipe a39. The gas flows in this way. The ultra-fine particles are delivered to the patient's respiratory tract to obtain a therapeutic effect. The user can maintain continuous inhalation therapy as long as the drug core is added to the drug solution as needed or the entire flavor device core a36 is replaced.

There are two types of power sources used in the present invention: alternating current (mains) and batteries.

The above-mentioned negative pressure source machine, positive pressure source machine, differential pressure sensor kit, and the following ultraviolet lamps all require direct current to provide power. Since the main users of the present invention are patients with respiratory system diseases, most of the use environments are in hospital wards. Therefore, it is the most economical to connect to alternating current (mains), and an alternating current to direct current conversion module needs to be configured. A battery also needs to be configured so that the present invention can continue to operate when the user leaves the hospital bed for a short time. For example, when the user goes to the toilet.

Its volume is slightly smaller than the space in the center of the above-mentioned spiral airflow pipe. The generated ultraviolet rays are mainly short-wave ultraviolet rays, which are used to kill pathogenic microorganisms.

The shape of the above-mentioned microbial filter sleeve is similar to the American "Uncle Sam" type top hat, and the edge of the "top hat" has the same number of holes as the position and number of the small holes of the above-mentioned lamp base plate, which is called the fixed hole b08 of the microbial filter sleeve, which is used for The lamp socket board b01 is attached and fixed. This filter sleeve is made of high-efficiency filter material. According to the size of the pathogenic microorganisms to be filtered, the type and quantity of the filter material are also different. The commonly used filter material is the melt-blown cloth for making N95 masks or N99 masks. You can also choose a filter material made of HEPA, cover the inner surface of the filter material with a hydrophobic layer of the same material as the inner layer of the N95 mask, and cover the outer surface with a protective layer of the same material as the outer layer of the N95 mask. When in use, the filter sleeve covers the spiral airflow tube and the self-ballasted UV lamp in the center.

The above-mentioned chemical disinfecting filter layer is the last line of defense of the microorganism interception component of the present invention, and is composed of multiple layers of materials with filtering effect. Commonly used filter materials include high-efficiency filter cotton, medium-efficiency filter cotton, melt-blown cloth, and multi-layer cotton yarn. cloth, sponge, activated carbon. Among them, some materials need to be impregnated with disinfectant (such as multi-layer cotton gauze or sponge). According to the different pathogenic microorganisms to be dealt with, one or more of the above-mentioned filter materials and a disinfectant with a targeted disinfecting effect are selected to be superimposed together to form a composite disinfecting filter layer.
