[0002] Sputum testing is a commonly used clinical examination method. It helps determine whether there are suspicious lesions and find tumor cells in the sputum by examining the characteristics of the sputum. It plays an important role in diagnosing lung tumors, guiding the use of antibiotics through sputum culture, etc.

[0003] The sputum specimen collector currently used in clinical practice is a small plastic cup container with a diameter of 3 cm and a height of 4 cm with a lid. There are the following difficulties in using this sputum cup to collect sputum specimens: 1) the opening of the plastic cup is small and does not fit the patient's mouth shape; 2) if the attached Figure 3 As shown, the lid of the plastic cup is mostly non-threaded and is simply a flip-up lid covering the outside of the plastic cup. It is very easy to fall off the plastic cup during transportation, causing contamination of the sputum sample. Utility Model Content

[0031] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0032] Example 1

[0033] See also Figure 1-3 The technical solution of a novel sputum sample collector provided in this embodiment includes the following:

[0034] A storage bag 1 for accommodating sputum specimens, wherein the top of the storage bag 1 is provided with a feeding port;

[0035] a first sealing member 2, wherein the bottom of the first sealing member 2 is fixedly connected to the feed port, and the inner cavity of the first sealing member 2 is in communication with the storage bag 1;

[0036] The sealing cover 3 is provided with a second sealing member 31 , and the second sealing member 31 cooperates with the inner cavity of the first sealing member 2 to seal the storage bag 1 .

[0037] Preferably, in an unused state, the second sealing member 31 of the sealing cover 3 is accommodated in the inner cavity of the first sealing member 2 , and the second sealing member 31 and the first sealing member 2 are interference fit.

[0038] In a specific implementation, the first sealing member 2 is a collecting neck, which has an inverted hollow cone structure. The inner wall of the collecting neck is smooth, and the structure with a larger upper end face and a smaller lower end face makes its inner wall tilted toward the center of the lower end face, which can better help the sputum sample slide down, that is, the inner wall of the collecting neck forms a sliding guide surface for the sputum sample.

[0039] Preferably, in addition to its function of sealing with the second sealing member 31, the collecting neck also has a function of facilitating hand-held spitting. Therefore, the collecting neck and the sealing cover 3 are made of a flexible medical plastic material including polyvinyl chloride.

[0040] Specifically, the middle portion of the sealing cover 3 is recessed downward to form an inverted truncated cone structure, and the recessed portion of the sealing cover 3 is the second sealing member 31 .

[0041] Preferably, in order to achieve a better sealing effect, the size of the second seal 31 can be designed to be slightly larger than the inner cavity of the first seal 2, so that the inner cavity of the first seal 2 and the second seal 31 have an interference fit; and the height of the second seal 31 should not be too short, and can be designed to match the height of the inner cavity of the first seal 2 or be slightly larger than the height of the inner cavity of the first seal 2.

[0042] Specifically, the cover body and the sputum inspection box in the prior art are independent and separated structures. The cover body is easily lost during use by the patient, resulting in the inability to seal the sample. Therefore, this design connects the sealing cover 3 and the first sealing part 2 through a hinge 32, and the two ends of the hinge 32 are respectively connected to the same side edges of the sealing cover 3 and the first sealing part 2. Under this structure, the sealing cover 3 is always connected to the first sealing part 2 and will not be lost, thereby reducing consumables.

[0043] Specifically, in order to facilitate opening of the sealing cover 3 , a force application point needs to be provided on the cover body, and therefore a hand rest 33 is provided on the other side edge of the sealing cover 3 away from the hinge 32 .

[0044] Specifically, the storage bag 1 includes a bottomless bag body 11 and a bottom film 12 arranged at the bottom of the bag body 11, and the edge of the bottom film 12 is connected to the lower end of the bag body 11 through heat sealing treatment; the bottom film 12 is folded toward the inner cavity of the bag body 11 and stored in the bag body 11.

[0045] Preferably, under this structure, when not in use, the bottom film 12 can be folded to reduce the storage space; when in use, the bottom film 12 can be stretched out to make the storage bag 1 into an upright barrel shape, which is more convenient for spitting. The material of the storage bag 1 can also be sealed medical plastic.

[0046] Specifically, the height of the first sealing member 2 is designed to be 2 to 3 cm for easy handling. The width of an adult's pursed lips is typically between 20 and 50 mm (2 to 5 cm). To facilitate spitting, the outer diameter of the upper end of the first sealing member 2 is set to 4 to 5 cm. To form an inclined inner wall, the outer diameter of the lower end of the first sealing member 2 is set to 3 to 4 cm. Furthermore, the length of the storage bag 1 is set to 4 to 5 cm.

[0047] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art in the field of medical care technology may still modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
