Description

Technical Field

[0001] The embodiments of the present invention relate to the technical field of protective masks, and in particular to a protective mask with a self-detection function. Background Art

[0002] Respiratory infections are generally transmitted through the mouth and nose, such as the novel coronavirus pneumonia. Wearing a mask can significantly reduce the risk of infection. However, current masks only block viruses. Whether a person is infected with a specific virus can only be determined through specialized sampling and testing. Therefore, there is a significant time lag between infection and detection, which poses a significant risk to personal health and epidemic prevention testing.

[0003] Therefore, in daily life, if the structure of existing protective masks is improved, on the one hand, it can effectively block viruses, bacteria, etc. and reduce the risk of transmission of bacteria and viruses. On the other hand, it can timely detect human health status, allowing users to pay attention to their own health risks in a timely manner, which will greatly improve public safety. Summary of the Invention

[0004] The embodiment of the present invention provides a protective mask with a built-in detection function. To address the defects of existing protective masks that have a single function and cannot realize the detection function, a new design concept is adopted, so that the mask can not only block viruses from entering the respiratory tract, but also reflect the specific virus infection situation inside the human body.

[0008] The condensation unit includes: a patch, a condensation tube and a fixed end cap;

[0009] The outer layer of the mask is provided with a through hole for passing the condenser tube at a position corresponding to the mouth and nose. The fixed end cap is provided at one end of the condenser tube for fixing the condenser tube at a preset position.

[0013] The detection unit includes: a detection tube and a detection reagent strip;

[0014] The detection tube is arranged below the outer layer of the mask, and the detection reagent strip is arranged in the detection tube;

[0015] The detection tube comprises: a positioning base tube, a liquid storage tank, and a liquid storage membrane;

[0016] A positioning cavity for fixing the liquid storage tank is provided inside the positioning base tube, and the liquid storage tank is arranged in the positioning cavity, and the liquid storage tank is used to receive the liquid water flowing in from the liquid inlet;

[0017] A liquid discharge port is provided on a side of the liquid storage bin close to the detection reagent strip, and the liquid storage membrane is fixed on the liquid discharge port;

[0018] The liquid storage membrane is provided with an overflow port, and the overflow port is located above the liquid discharge port. The liquid storage membrane is used to collect a certain amount of liquid water and discharge it onto the detection reagent strip.

[0019] By adopting this technical solution, the protective mask with built-in detection function has added a detection function on the basis of the existing protection function. Without the need for users to perform other operations, it can perform detection after cooling enough liquid water, taking into account both protection and detection. At the same time, it is more convenient and less costly than special detection.

[0020] In a feasible solution, a sealing film is provided at the outlet of the accommodating cavity, and condensate is also sealed in the accommodating cavity.

[0021] By adopting this technical solution, since the warm gas is cooled by means of condensate, the cooling efficiency can be greatly improved, the amount of liquid water can be increased, and the detection time can be shortened.

[0022] In a feasible solution, the condenser is made of a soft heat-conducting material.

[0023] This technical solution is adopted to improve the wearing comfort of the mask.

[0024] In a feasible solution, two detection cavities are symmetrically arranged in the detection tube, and the detection reagent strips are respectively arranged in the detection cavities.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments.

[0043] In the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integrated connection; it can be a mechanical connection, an electrical connection, or a communication connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined.

Figure 6 Schematic diagram of the internal structure of the detection tube in an embodiment of the present invention.

[0045] like Figures 1 to 5 As shown, the present invention provides a protective mask with a self-detection function, comprising a mask outer layer 1 and a mask lining 2, and also comprising: a detection component 3.

[0046] Among them, the materials and structures of the outer layer 1 and the inner layer of the mask can refer to existing masks.

[0047] The detection component 3 includes: a condensation unit and a detection unit.

[0048] Among them, the condensation unit is arranged at the position corresponding to the mouth and nose of the outer layer 1 of the mask, as shown in the figure, which is used to facilitate the drainage of the gas exhaled from the mouth and nose, so that the drained warm air can be fully heat exchanged inside the condensation unit to achieve the generation of liquid water. The generated liquid water can be used as a test sample to detect a certain pathogen.

[0049] The detection unit is set on the outer layer 1 of the mask. The purpose of setting the detection unit on the outer layer 1 of the mask is to facilitate the user or others to observe the detection results. It should be noted that there are many ways to set the detection unit on the outer layer 1 of the mask. One possible setting method is Figure 2 As shown in , the detection unit is arranged below the mask, and the detection unit is used to receive liquid water and detect the liquid water.

[0050] It should be noted that in order to enable users to observe the test results in a timely manner, the test unit should be conveniently displayed. For example, if the test unit is set to be transparent, the user can directly observe the test results through the test unit.

[0051] The working principle of this protective mask with built-in detection function is: warm gas is guided out from the mouth and nose, and this part of the gas is condensed in the condensation unit to form liquid water containing specific pathogens. The generated liquid water is then tested using the detection unit, and the test results are displayed through the detection unit to facilitate users or others to observe the results in time, providing a timely reference for reflecting the user's health status.

[0052] By adopting this technical solution, the protective mask with built-in detection function has added a detection function on the basis of the existing protection function. Without the need for users to perform other operations, it can perform detection after cooling enough liquid water, taking into account both protection and detection. At the same time, it is more convenient and less costly than special detection.

[0053] In a feasible solution, the detection unit includes: a detection tube 4 and a detection reagent strip.

[0054] One possible arrangement of the detection tube 4 is to place the detection tube 4 below the outer layer 1 of the mask, making the detection tube 4 a part of the mask. A detection reagent strip is placed inside the detection tube 4, and when liquid water flows into the detection tube 4, it can crawl on the detection reagent strip.

[0055] This technical solution utilizes existing technologies, especially existing detection reagent strips, and can effectively reduce costs.

[0056] In a feasible solution, the condensation unit includes: a patch 301 , a condensation tube 302 and a fixed end cap 303 .

[0057] A possible patch 301 is made of soft rubber, and the patch 301 must have good thermal conductivity.

[0058] The outer layer 1 of the mask is provided with a through hole 101 for passing the condenser tube 302 at the position corresponding to the mouth and nose. Figure 1 As shown, each through hole 101 corresponds to a condenser tube 302. The fixed end cap 303 is set at one end of the condenser tube 302. One possible setting method is: an external thread is set at one end of the condenser tube 302 (the air inlet 305), and an internal thread is set on the fixed end cap 303, so that the fixed end cap 303 can be fixed on the condenser tube 302 through the thread. The fixed end cap 303 is located between the outer layer 1 and the inner layer of the mask. The structure of the fixed end cap can refer to Figure 4 , used to fix the condenser 302 at a preset position to facilitate the diversion of the warm gas exhaled from the mouth and nose.

[0059] The patch 301 is provided with a receiving cavity. It should be noted that the thickness of the receiving cavity can be set to be thinner to facilitate the fit of the mask on the face. The patch 301 is fixed to the outer layer 1 of the mask and is made of a thermally conductive material. Since there are many organic materials with thermal conductivity on the market, they will not be described in detail here.

[0060] The condenser tube 302 is located within the chamber and can be bent to extend its length for improved condensation. The condenser tube 302 has an air inlet 305 positioned near the nose and mouth, and a liquid outlet 304 at the other end, where liquid water flows out. This outlet 304 is in communication with the liquid inlet 401 on the detection tube 4.

[0061] This technical solution provides a method for fixing the condensation unit on the mask, which has the advantages of simple structure and will not cause excessive impact on the protective function of the mask.

[0062] In one feasible solution, condensate is also sealed within the chamber. It should be noted that the condensate needs to be stored in a sealed manner within the chamber. One possible sealing method is to place a sealing film over the chamber, which forms a seal with the outlet of the condensation tube 302. The condensate can be water or medicinal alcohol. The medicinal alcohol is used so that the mask can be disinfected by puncturing the sealing film after use.

[0063] By adopting this technical solution, since the warm gas is cooled by means of condensate, the cooling efficiency can be greatly improved, the amount of liquid water can be increased, and the detection time can be shortened.

[0064] In a feasible solution, the condenser 302 is made of a soft heat-conductive material.

[0065] This technical solution is adopted to improve the wearing comfort of the mask.

[0066] In a feasible solution, two detection cavities are symmetrically arranged in the detection tube 4, such as Figure 5 As shown, two detection chambers are symmetrically arranged at both ends of the detection tube 4, and each liquid inlet 401 corresponds to one detection chamber. Detection reagent strips are respectively arranged in the detection chambers on both sides.

[0067] This technical solution is adopted to provide two test results and improve the accuracy and reliability of the test results.

[0068] In a feasible solution, the mask further includes an adsorption protection plug 5. The adsorption protection plug 5 is made of an organic material that is breathable and adsorbs pathogens, and is used to filter and remove a small amount of gas discharged from the detection tube 4 to avoid damaging the protective function of the mask.

[0069] Adsorption protection plugs 5 are arranged at both ends of the detection tube 4 .

[0070] This technical solution is adopted to make the protective function of the mask more perfect and avoid destroying the protective function of the mask.

[0071] In a feasible solution, the detection tube 4 includes: a positioning base tube 402 , a liquid storage tank 6 , and a liquid storage membrane 7 .

[0072] The function of the positioning base tube 402 is to provide installation space for the liquid storage tank 6 and the detection reagent strip 8. Figure 6 The figure shows the internal structure of the detection tube 4. Two positioning cavities are symmetrically positioned at the center of the positioning base tube 402, with one end of the liquid reservoir fixed within the positioning cavity. The liquid reservoir 6 is hollow and has a certain degree of flexibility to facilitate installation. The liquid reservoir 6 has inlets corresponding to the liquid inlet 401 and the liquid outlet 304, which are used to receive liquid water flowing in from the liquid inlet 401.

[0073] A liquid discharge port is provided on one side of the liquid storage bin 6 near the test strip 8. A possible liquid discharge port is to provide an open notch on the side of the liquid storage bin 6 near both ends of the test tube. The liquid storage membrane 7 is fixed on the liquid discharge port in the form of an adhesive.

[0074] It should be noted that the liquid storage film 7 is provided with an overflow port 701. The overflow port 701 has various shapes. One possible shape is Figure 6 The long strip hole shape shown in . It should be noted that the purpose of providing the liquid storage membrane 7 is that after a certain amount of liquid water is collected in the liquid storage tank 6, the liquid water erodes and destroys the structure of the liquid storage membrane 7, and the liquid level of the liquid water is higher than the lower edge of the overflow port 701. Therefore, when the liquid surface tension cannot maintain its liquid level, a sufficient amount of liquid water is discharged to the outside of the overflow port 701 at one time. Since the detection reagent strip 8 is located on the lower side of the overflow port 701, the structural design of the overflow port 701 can achieve the purpose of sufficient liquid water flowing into the detection reagent strip 8 for detection. In order to increase the liquid level maintained by the liquid surface tension, a ciliary edge can be provided on the overflow port 701 to achieve the purpose of increasing the amount of liquid water that can be detected.

[0075] It should be noted that the material of the liquid storage membrane 7 can be a thin paper material, or it can be an organic film material that is easily damaged after soaking. The liquid storage membrane 7 needs to have the following properties: when the liquid storage membrane 7 is just storing liquid, it can prevent large amounts of liquid water from leaking out. After a certain period of liquid storage, when the liquid level reaches a certain height, the material of the liquid storage membrane 7 is destroyed, allowing the liquid water to flow out in large quantities at the moment when it can no longer be held. Experiments have found that permeable paper with a thickness of 0.04mm to 0.055mm can basically meet this requirement. Organic film materials that achieve similar functions are existing technologies and are commercially available, so they will not be described in detail.

[0076] By adopting this technical solution, the collected liquid water can be accumulated to a sufficient amount and then discharged into the detection reagent strip 8, which can improve the crawling effect of the detection liquid water on the detection reagent strip 8, thereby improving the accuracy of the detection.

[0077] In one feasible solution, the centerline of the overflow port 701 is tilted. It should be noted that the centerline of the overflow port 701 refers to the centerline position of the mask when normally worn. The side close to the liquid inlet is kept at a normal height, while the side away from the liquid inlet is slightly higher. This keeps the liquid surface in the liquid storage tank 6 at a slight tilt, maximizing the tension between the liquid surface and the inside of the liquid storage tank 6, thereby increasing the liquid storage capacity in the liquid storage tank 6.

[0078] This technical solution is adopted to maximize the amount of stored water and ensure that sufficient liquid water flows onto the test strip 8. In the present invention, unless otherwise specified or limited, the first feature being "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or the first feature and the second feature are in indirect contact through an intermediate medium.

[0079] Furthermore, when a first feature is “above,” “above,” or “above” a second feature, it may mean that the first feature is directly above or obliquely above the second feature, or simply means that the first feature is higher in level than the second feature. When a first feature is “below,” “below,” or “below” a second feature, it may mean that the first feature is directly below or obliquely below the second feature, or simply means that the first feature is lower in level than the second feature.

[0080] In the description of this specification, reference to the terms "one embodiment", "some embodiments", "example", "specific example" or "some examples" means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present invention.

Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner.
