Description

Technical Field

[0001] This utility model relates to the field of medical supplies technology, and in particular to a sputum collector. Background Technology

[0002] Tuberculosis is a chronic infectious disease caused by Mycobacterium tuberculosis. While the bacteria can invade various organs throughout the body, it primarily affects the lungs, leading to pulmonary tuberculosis.

[0003] Mycobacterium tuberculosis, commonly known as tuberculosis bacillus, is the pathogen that causes tuberculosis. Currently, the main methods for detecting Mycobacterium tuberculosis include etiological methods, immunological methods, and molecular biological methods. Etiological detection is currently the only definitive method for diagnosing tuberculosis. Etiological methods include sputum smear testing, which is a rapid, inexpensive, and easy-to-perform clinical diagnostic method. Sputum is collected, processed, and smeared, then analyzed. Currently, sputum smear testing mainly relies on manual experience to add sputum digestion fluid for liquefaction. During the testing process, the testing personnel need to use one hand to unscrew the lid of the sputum container while using the other hand to add the sputum digestion fluid. This is difficult because unscrewing the lid with one hand is challenging, and with the container fully open, the sputum is prone to evaporation, potentially leading to infection of the testing personnel or environmental contamination.

[0004] Currently, sputum specimen collection generally requires patients who wish to cough up sputum to rinse their mouths with water before eating in the morning, take several deep breaths, and forcefully cough up sputum from deep within the trachea. The second sputum sample is then collected in a sputum container, which is then sealed and sent for testing. Sputum containers are typically wide-mouthed, sterile containers with lids, made of plastic or glass. However, existing sputum containers, when used by patients who wish to collect sputum, have open openings for extended periods, resulting in a large surface area and increasing the risk of specimen contamination. Furthermore, coughing up sputum can cause saliva and sputum to splatter, leading to environmental pollution.

[0005] A search revealed a patent with authorization announcement number CN 215605892 U, which discloses a disposable sputum specimen collection device with a face mask. The device includes a face mask, a connecting cap, a sealing cap, and a sputum collection cup. The face mask has breathing holes for patient breathing on both the front and back, near the upper left. A connecting tube is fixedly connected to the bottom of the face mask, and a connecting sleeve threaded to the outside of the connecting tube is fixedly connected to the center of the top of the connecting cap. This disposable sputum specimen collection device with a face mask effectively prevents sputum and saliva from splashing into the environment during coughing, thus preventing environmental pollution. Furthermore, by designing the inner cavity of the face mask as a funnel shape, sputum and saliva separate due to their different weights as they slide downwards, ensuring the quality of the sputum specimen.

[0006] In the aforementioned prior art, the funnel-shaped mask has the following problems: during spitting, the sputum has a certain stickiness, which means that the sputum spit onto the mask cannot enter the sputum collection cup. Also, the connecting sleeve on the connecting cover is in an open state, which leads to the problem of sputum evaporation and contamination. Summary of the Invention

[0007] The existing funnel-shaped mask has technical problems: during spitting, the sputum has a certain stickiness, which prevents the sputum that is spat onto the mask from entering the sputum collection cup; and the connecting sleeve on the connecting cover is in an open state, which leads to the evaporation of sputum and causes contamination.

[0008] Technical approach: Based on the problems of existing technologies, this application provides a sputum collector. By setting a mask that fits snugly around the mouth and has an internal cavity, sputum can be directly spat into the sputum container, thus achieving sputum collection and avoiding the problem of sputum sticking and being unable to enter the sputum container. Furthermore, the concentric rotating mechanism on the cover allows for the addition of sputum digestion fluid to the sputum container after sputum is sent for testing without opening the cover, achieving convenient operation and effectively preventing sputum evaporation.

[0009] To achieve the above technical concept, the technical solution adopted by this utility model is as follows: This application provides a sputum collector, including a mask and a sputum box threadedly connected to the mask, and further including: a cover rotatably connected to the sputum box, the cover being threadedly engaged with the sputum box; the cover has a through-hole for adding liquid, and a concentric rotating mechanism for adding sputum digestion fluid is provided at the position corresponding to the liquid inlet on the cover.

[0010] Specifically, the mask fits snugly around the mouth and has an internal cavity. The mask has ear loops symmetrically arranged on both sides and a screw interface that matches the opening of the sputum box. The screw interface has internal threads.

[0011] It should be noted that the earring is elastic, for example, it can be made of elastic cord or elastic band, but is not limited to these.

[0012] In detail, the sputum box is a cylindrical cavity structure with an opening at the top, and the opening of the sputum box is provided with external threads.

[0013] More specifically, the cover is provided with internal threads.

[0014] Furthermore, the concentric rotation mechanism includes: a fixed block connected to the cover, a plurality of guide rods provided on the outer periphery of the fixed block, and a through hole opened at the center of the fixed block; a rotating ring sleeved inside the liquid filling port, a plurality of guide grooves opened on the outer periphery of the rotating ring, and a plurality of rotating rods rotatably connected to the inner periphery of the rotating ring, and a rotating blade rotatably connected to the end of each rotating rod. As an example, the fixing block is a circular structure, the guide rod is a "T" shaped structure, the through hole is a circular through hole, the rotating ring is a circular ring structure, the guide groove is an arc-shaped structure, the rotating rod is an arc-shaped rod, and the rotating blade is a triangular blade structure.

[0015] The guide groove and guide rod are rotatably connected, and the rotating blade is rotatably connected to the fixed block.

[0016] Furthermore, the concentric rotation mechanism also includes: a lever fixedly connected to the rotating ring, and a limiting hole provided on the cover, wherein the end of the lever is inserted into the limiting hole.

[0017] In detail, the actuating lever has a "U" shaped structure, and the end connected to the rotating ring is retractable.

[0018] Preferably, a limiting groove is provided near the opening of the sputum box, and a connecting ring is connected to the cover, which is rotatably fitted into the limiting groove on the sputum box.

[0019] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model connects a face mask to a sputum container by threads, and the face mask is worn on the face by ear loops on the face mask. This allows the patient to spit into the sputum container while preventing sputum from splashing out and causing environmental pollution. On the other hand, it allows the sputum to be spit directly into the sputum container, avoiding the problem of sputum sticking to the face mask and causing pollution or insufficient sputum detection.

[0020] 2. This utility model connects the cover to the sputum box by cooperating with the connecting ring and the limiting groove, so that the cover can be screwed onto the sputum box immediately after the sputum is collected. This avoids the problem of storing the cover separately or looking for another cover, which would cause the sputum box to be left open for a long time and the sputum to evaporate.

[0021] 3. This utility model features a liquid inlet through the cover and a concentric rotation mechanism within it. By rotating a lever, a rotating ring is driven to rotate under the limiting action of a guide groove and a guide rod. During the rotation of the rotating ring, the rotating rod drives the rotating blades to rotate, thereby opening and closing the through hole on the fixed block, and thus opening and closing the liquid inlet. This allows testing personnel to easily add sputum digestion fluid to the sputum container through the liquid inlet after the sputum is submitted for testing. This solves the problem that it is difficult for testing personnel to open the sputum container with one hand while adding sputum digestion fluid with the other, and the problem that opening the sputum container cover as a whole can easily cause sputum evaporation.

[0024] To enable those skilled in the art to better understand the technical solution of this utility model, the technical solution of this utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0025] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "front end", "rear end", "inner side", "outer side", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0026] In the description of this application, it should also be noted that, unless otherwise expressly specified and limited, the terms "set up," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0027] In practical operation, the inventors found that when sputum testing personnel use the sputum smear method to test sputum, they need to use one hand to unscrew the lid of the sputum container while adding sputum digestion fluid to the container for liquefaction with the other hand. It is difficult to unscrew the lid with one hand, and the lid is easy to cause sputum to evaporate after being opened, especially the sputum of patients infected with tuberculosis, which can easily cause contamination after evaporation.

[0028] Based on the above findings, this application provides a sputum collector, including a mask 1 and a sputum box 2 threadedly connected to the mask 1, and further including: a cover 3 rotatably connected to the sputum box 2, the cover 3 being threadedly engaged with the sputum box 2; the cover 3 having a through-hole 4 for adding liquid, and a concentric rotating mechanism 5 for adding sputum digestion fluid is provided at the position corresponding to the liquid inlet 4 on the cover 3.

[0029] Example 1 Reference Figure 1-5 As shown, this application provides a sputum collector, including a mask 1 and a sputum container 2 threadedly connected to the mask 1, and further including a cover 3 rotatably connected to the sputum container 2, the cover 3 being threadedly engaged with the sputum container 2.

[0030] Specifically, the mask 1 fits snugly around the mouth and has an internal cavity. The mask 1 has ear loops 11 symmetrically arranged on both sides, and a screw interface 12 that matches the opening of the sputum box 2.

[0031] It should be noted that the earring 11 is elastic. For example, an elastic cord can be used, but it is not limited to this; an elastic rubber band can also be used.

[0032] The mask 1 is fixed to the face by hanging earrings 11, so that the nose is exposed by the mask 1, thus not affecting breathing through the nose. The mask 1, which fits around the mouth, can block the splashing of phlegm during spitting.

[0033] It is fixed by screwing the internal thread on the screw interface 12 to the external thread on the spittoon box 2, which has good stability.

[0034] It should be noted that when the patient wears the mask 1 on their face, the mouth is close to the screw interface 12, so that the sputum can directly enter the sputum container 2 when spitting, avoiding the problem that a large amount of sputum sticks to the mask 1 and cannot enter the sputum container 2, which would cause insufficient sputum collection during testing.

[0035] After the sputum collection is completed, the mask 1 is removed from the sputum container 2. In order to quickly seal the sputum container 2, a lid 3 is attached to the sputum container 2.

[0036] Specifically, a limiting groove 21 is provided near the opening of the sputum box 2, and a connecting ring 6 is connected to the cover 3. The connecting ring 6 is rotatably fitted into the limiting groove 21 on the sputum box 2.

[0037] The internal thread on the cover 3 is engaged with the external thread on the spittoon 2 to achieve a tight seal. During the process of screwing the cover 3, the connecting ring 6 rotates with the cover 3 within the limiting groove 21.

[0038] Example 2 Based on Example 1, referring to Figure 1-2 As shown in 6-7, after the sputum is collected and sent for testing, in order to facilitate the testing personnel to add sputum digestion fluid to the sputum in the sputum box 2 to dilute the sputum, a liquid inlet 4 is provided through the cover 3. A concentric rotating mechanism 5 for adding sputum digestion fluid is provided at the position corresponding to the liquid inlet 4 on the cover 3.

[0039] In the above technical solution, the concentric rotation mechanism 5 includes: a fixed block 51 fixedly connected to the cover 3, a plurality of guide rods 52 are provided on the outer periphery of the fixed block 51, and a through hole 53 is opened at the center of the fixed block 51; the sputum digestion fluid can be added through the through hole 53.

[0040] Furthermore, it also includes a rotating ring 54 rotatably sleeved inside the liquid inlet 4. The outer circumference of the rotating ring 54 is provided with multiple guide grooves 55, and the inner circumference of the rotating ring 54 is rotatably connected with multiple rotating rods 56. The end of each rotating rod 56 is rotatably connected with a rotating blade 57. The rotating blade 57 is rotatably connected to the fixed block 51 through the rotatable engagement of the guide grooves 55 and the guide rods 52.

[0041] As an example, the rotating ring 54 and the rotating rod 56, the rotating rod 56 and the rotating blade 57, and the rotating blade 57 and the fixed block 51 are rotatably connected by hinges or shafts.

[0042] As an example, the rotating blades 57 are provided in five.

[0043] Furthermore, the concentric rotation mechanism 5 further includes: a toggle rod 58 fixedly connected to the rotating ring 54, and a limiting hole 59 provided on the cover 3, wherein the end of the toggle rod 58 is inserted into the limiting hole 59.

[0044] It should be noted that the end of the lever 58 that is rotatably connected to the rotating ring 54 can be extended or retracted. As an example, it can be in the form of a telescopic rod. The structure of the telescopic rod is existing technology, and the inventor has not made any improvements. The existing telescopic rod structure can be applied to the lever 58 in this application. Those skilled in the art can implement it, so it will not be described again.

[0045] Specific application examples The specific application of a sputum collector of this application in the collection and detection of sputum from tuberculosis patients is now described in detail with reference to Embodiment 1 and Embodiment 2.

[0046] Mycobacterium tuberculosis, commonly known as tuberculosis bacillus, is the pathogen that causes tuberculosis. Currently, the main methods for detecting Mycobacterium tuberculosis include etiological methods, immunological methods, and molecular biological methods. Etiological detection is currently the only definitive method for diagnosing tuberculosis. An example of an etiological method is the sputum smear test, which is a rapid, inexpensive, and easy-to-perform clinical diagnostic method. Sputum is collected, processed, and then smeared for testing.

[0047] Tuberculosis sputum testing requires collecting sputum samples at three different time periods: "immediate sputum" (sputum coughed up on the spot during the consultation), "morning sputum" (sputum coughed up deeply after waking up), and "nighttime sputum" (sputum coughed up at night). Three samplings improve testing accuracy and avoid missed diagnoses.

[0048] Rinsing your mouth with water before sputum collection can remove food debris and bacteria from the oral cavity, reducing contamination of the sputum. During the sputum collection process: the person collecting the sputum wears a mask 1 connected to a sputum container 2 on their face through earring 11, takes a deep breath, bends over, and coughs forcefully, spitting the coughed-up sputum directly into the sputum container 2 through the screw connector 12. After the sputum is collected, remove the mask 1 and detach it from the sputum container 2.

[0049] Then quickly screw the cover 3 connected to the sputum container 2 onto the sputum container 2 to seal the sputum container 2 and prevent sputum from evaporating or becoming contaminated.

[0050] The sealed sputum container 2 is promptly sent to the testing area for analysis. During the testing process, the testing personnel need to add sputum digestion solution and sterile saline to the sputum container 2 to dilute it and shake the sputum to mix it evenly. The testing personnel pull out the actuating rod 58 from the limiting hole 59 and then rotate the actuating rod 58. During the rotation of the actuating rod 58, the rotating ring 54 is driven to rotate under the cooperation of the guide groove 55 and the guide rod 52. During the rotation of the rotating ring 54, the rotating rod 56 and the rotating blades 57 are driven to rotate, thereby causing the rotating blades 57 to rotate and separate, forming a gap at their center position. This opens the through hole 53 on the fixing block 51, making it easier for the testing personnel to add sputum digestion solution to the sputum container 2 through the liquid filling port 4 and the through hole 53.

[0051] After the sputum digestion fluid is added, reverse the lever 58. The lever 58 drives the rotating ring 54 to rotate, which in turn drives the rotating blade 57 to rotate and reset through the rotating rod 56. This causes the rotating blade 57 to completely seal the through hole 53, thus achieving the sealing of the sputum box 2.

[0052] Further shake the sputum container 2 to mix it well, and finally perform a smear test on the mixed sputum to complete the sputum collection and testing process.

[0053] In summary, although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
