Description

Technical Field

[0001] The utility model relates to the technical field of experimental instruments, in particular to a breath microorganism sampler. Background Art

[0002] Existing exhaled breath microbial sampling devices can collect microorganisms in the air of the target environment through aeration, and can also use quantitative detection technology to calculate the amount of pathogenic microorganisms contained in a unit of air. However, current microbial sampling devices usually use repeated aeration in the collection liquid to collect microorganisms in the exhaled breath. Because the distance between the air outlet and the air inlet is usually short, and the collector's exhaled breath is uneven, it is impossible to ensure that the microorganisms in the collected gas can be efficiently captured during the collection process, resulting in a large number of ineffective cycles. Therefore, there is an urgent need to develop a sampler that can quickly and effectively collect human exhaled microorganisms. Utility Model Content

[0003] In order to solve the above technical problems, the utility model proposes a breath microorganism sampler, which can achieve rapid collection by freezing the microorganisms in the breath, thereby improving the collection efficiency.

[0004] To achieve the above purpose, the present invention provides the following solutions:

[0005] A breath microbial sampler comprises a breathing mask, one end of which is detachably connected to a spiral tube, one end of which is penetrated by a storage barrel, and the other end of which is penetrated by a cover plate, which is adapted to and detachably connected to the top end of the storage barrel inner cavity, a support block is clamped in the middle of the spiral tube, and the support block is placed on the bottom surface of the storage barrel inner cavity; the storage barrel inner cavity is filled with dry ice or liquid nitrogen.

[0007] Preferably, the inner cavity at the other end of the spiral tube is detachably connected to a ring plug, and the bottom end of the ring plug is sleeved with a filter layer.

[0012] Compared with the prior art, the present invention has the following advantages and technical effects:

[0013] The utility model can guide the exhaled gas of the human body into the spiral tube by buckling the breathing mask on the mouth of the face. By cooling the spiral tube with the rapid refrigerant dry ice or liquid nitrogen, the exhaled gas of the human body is cooled, and the microorganisms in the exhaled gas are frozen and adhered to the inner wall of the spiral tube, thereby achieving the collection and maintenance of the activity of the microorganisms.

[0018] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0019] It should be noted that all components in the technical solution of this application require necessary additional facilities for water supply, oil supply, electricity supply and gas supply for driving and / or control. If there is no further explanation, it is assumed that the existing technology is used and equipped, and no special explanation is required.

[0020] It should be noted that, in order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0021] Depend on Figure 1-2 The breath microorganism sampler shown includes a breathing mask, one end of which is detachably connected to a spiral tube 1, one end of which is penetrated by a storage barrel 2, and the other end of which is penetrated by a cover plate 3, which is adapted to and detachably connected to the top end of the inner cavity of the storage barrel 2, a support block 4 is clamped in the middle of the spiral tube 1, and the support block 4 is placed on the bottom surface of the inner cavity of the storage barrel 2; the inner cavity of the storage barrel 2 is filled with dry ice or liquid nitrogen.

[0022] Furthermore, the gap between the side wall of the support block 4 and the inner wall of the storage tube 2 is larger than the distance between one end surface of the spiral tube 1 and the inner wall of the storage tube 2 , which facilitates the installation of the spiral tube 1 on the storage tube 2 .

[0023] A further optimized solution includes a mask body 5, one end of which is fixedly connected to and communicates with a connecting tube 6. One end of the connecting tube 6 is detachably connected to a sealing plug 7. The end surface of the sealing plug 7 has a through hole, which is sleeved around one end of a spiral tube 1 and detachably connected thereto. The spiral tube 1 is in communication with the inner cavity of the mask body 5. By sleeve-fitting the connecting tube 6 over one end of the spiral tube 1, the air resistance of human exhalation can be reduced, thereby improving the efficiency of air collection.

[0024] To further optimize the solution, the inner cavity at the other end of the spiral tube 1 can be detachably connected to a ring plug 8, and the bottom end of the ring plug 8 is provided with a filter layer 9. Furthermore, the ring plug 8 is a rubber plug, and the ring plug 8 can seal the filter layer 9 at the outlet at the other end of the spiral tube 1, so as to facilitate filtering of the exhaled air.

[0025] Furthermore, the filter layer 9 is a sterile non-woven filter paper, which has good air permeability and adhesion properties to microorganisms such as bacteria and viruses. It is a prior art and will not be described in detail here.

[0026] To further optimize the solution, the spiral tube 1 is a copper tube, and the inner wall of the spiral tube 1 is chrome-plated. The copper tube can quickly transfer the gasification refrigeration capacity of dry ice or liquid nitrogen, which is convenient for cooling and freezing the exhaled air.

[0027] To further optimize the solution, the side wall of the mask body 5 is also fixedly connected to and communicated with an air inlet pipe 10, and the air inlet pipe 10 is fixedly connected to and communicated with the nebulizer (which is a prior art and will not be described again here or shown in the accompanying drawings). In order to improve the collection effect of microorganisms, the humidity of the exhaled air is increased in the mask body 5 to improve the freezing efficiency.

[0028] A further optimized solution is that a plurality of air holes are opened on the top surface of the cover plate 3, and the air holes are detachably connected to the air blocking plugs 11, and the top surface of the air blocking plug 11 is fixedly connected to the connecting ring 12. When the utility model is not used temporarily, the air holes will be sealed by the air blocking plugs 11 to reduce the evaporation of dry ice or liquid nitrogen and reduce the loss of cooling capacity.

[0029] As a further optimization solution, the storage tube 2 is made of transparent tempered glass or high borosilicate glass, which can facilitate the sampling personnel to observe the sampling process and prevent insufficient cooling capacity of the refrigerant.

[0030] The working process of this embodiment is as follows:

[0031] The mask 5 is buckled onto the mouth of the collector. The collector needs to inhale through the nose and then exhale through the mouth. The exhaled gas is introduced into the spiral tube 1 through the mask 5 and the connecting tube 6. Because dry ice or liquid nitrogen is placed in the storage tube 2, the evaporation of dry ice and liquid nitrogen will greatly reduce the temperature of the inner cavity of the storage tube 2. The exhaled air is continuously conducted in the spiral tube 1 and continuously releases heat until the water vapor in the exhaled air is condensed and frozen. Because the microorganisms are used as condensation nuclei during the condensation of water vapor, they will be fixed. Excess gas will be discharged into the air through the other end of the spiral tube 1, and the remaining microorganisms will also be filtered through the filter layer 9 and screened again to maximize the collection efficiency of microorganisms.

[0032] After a certain period of collection, one end of the spiral tube 1 is disconnected from the connecting tube 6 and taken out of the storage tube 2. Sterile distilled water is used to flush the inner cavity of the spiral tube 1 from the other end to flush the microorganisms into the distilled water, thereby completing the collection of the microorganisms.

[0033] The above are merely preferred embodiments of the present application, but the scope of protection of the present application is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in this application should be included in the scope of protection of the present application. Therefore, the scope of protection of the present application should be based on the scope of protection of the claims.
