Description

Technical Field

[0001] This utility model relates to the field of test tube collection technology, specifically a biomedical sample collection device. Background Technology

[0002] Swabs are tools for collecting medical samples. They are used to collect and transfer samples from the human body for laboratory testing and diagnosis. After the swab is used to collect the sample, it needs to be collected and preserved in a test tube to facilitate subsequent analysis and testing.

[0003] Existing patent application number: 201821590224.2 A collection tube capable of detecting moisture content includes a top cover and a tube body, with the top cover nested on the top of the tube body; the top cover includes a baffle and a cover plate, the baffle is fixedly connected to the inner wall of the top cover, the cover plate is threadedly connected to the top of the top cover, the cover plate is rotatably connected to the top cover, and an electronic display screen is embedded inside the cover plate.

[0004] The aforementioned patent describes a collection tube. In actual use, after the swab is placed inside the test tube, the excess length needs to be broken off to ensure that the test tube can be properly closed. However, the opening of the test tube lacks a support structure, making it difficult to find a point of leverage when breaking the swab. Sometimes, it is necessary to bend it repeatedly to break it off. The large range of motion can easily cause the contents of the test tube to splash out, which affects its use. Therefore, we propose a biomedical sample collection device to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a biomedical sample collection device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a biomedical sample collection device, comprising a test tube body, a test tube opening, a test tube cap, and an auxiliary breaking mechanism. The test tube body has an integrally formed test tube opening at its top. The test tube opening can be threaded onto the test tube cap. An auxiliary breaking mechanism is provided inside the test tube opening. The auxiliary breaking mechanism includes a connecting band, a tube opening sleeve, an auxiliary sleeve, an opening, and a support block. The bottom edge of the test tube cap has a connecting band, and the end of the connecting band is connected to the tube opening sleeve. The connecting band is located at the top edge of the tube opening sleeve, and the tube opening sleeve is movably nested inside the test tube opening. An auxiliary sleeve is integrally formed on the inner wall of the tube opening sleeve. An opening is provided on the side of the auxiliary sleeve, and a support block is provided at the upper end of the front inner wall of the auxiliary sleeve.

[0007] Preferably, the connecting strip has a crease in the middle section of its surface.

[0008] Preferably, the height of the tube sleeve is not less than 2cm.

[0009] Preferably, the auxiliary sleeve is at the same height as the pipe opening sleeve.

[0010] Preferably, the longitudinal section of the support block is acute-angled.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] This invention incorporates an auxiliary breaking mechanism inside the test tube opening. After collecting a medical sample, the swab is inserted into the test tube body through the opening. When it is necessary to break off the excess length of the swab, the swab is moved into the auxiliary sleeve through the opening and bent forward. At this point, the rear of the swab abuts against the auxiliary sleeve, and the front of the swab abuts against the support block, providing two points of leverage for the swab to ensure rapid breakage. After the swab is broken, the tube opening sleeve is removed from inside the test tube opening. The auxiliary breaking mechanism does not alter the internal shape of the test tube opening and does not affect the subsequent removal of the contents of the test tube body.

[0013] This invention features a crease in the middle section of the connecting strip, allowing the connecting strip to be folded into two sections along the crease, thus enabling the tube cap and tube opening to be separated. Attached Figure Description

[0021] To further explain the technical solution of this utility model, a detailed description is provided below through specific embodiments.

[0022] Please see Figure 1-2This utility model provides a biomedical sample collection device, including a test tube body 1, a test tube opening 2, a test tube cap 3, and an auxiliary breaking mechanism 4. The test tube body 1 is integrally provided with a test tube opening 2 at the top. The test tube opening 2 can be threadedly connected to the test tube cap 3. The test tube opening 2 is provided with an auxiliary breaking mechanism 4 inside.

[0023] Please see Figure 3-6 This utility model provides a biomedical sample collection device. The auxiliary breaking mechanism 4 includes a connecting strap 41, a tube opening sleeve 42, an auxiliary sleeve 43, an opening 44, and a support block 45. The bottom edge of the test tube cap 3 is provided with a connecting strap 41, and the end of the connecting strap 41 is connected to the tube opening sleeve 42. The connecting strap 41 is located at the top edge of the tube opening sleeve 42. The tube opening sleeve 42 is movably nested inside the test tube opening 2. The inner wall of the tube opening sleeve 42 is integrally provided with an auxiliary sleeve 43. An opening 44 is opened on the side of the auxiliary sleeve 43. A support block 45 is provided at the upper end of the inner front wall of the auxiliary sleeve 43. When performing the breaking operation, the swab is inserted into the auxiliary sleeve 43 through the opening 44 and bent forward. At this time, the rear part of the swab abuts against the auxiliary sleeve 43, and the front part of the swab abuts against the support block 45, which can provide two points of force for the swab and ensure that the swab can be broken quickly.

[0024] To further explain, the connecting strip 41 has a crease 41a in the middle section of its surface, and the connecting strip 41 can be broken off from the crease 41a, allowing the tube sleeve 42 to be separated from the test tube cap 3.

[0025] To further explain, the height of the tube sleeve 42 is not less than 2cm, so as to ensure that the tube sleeve 42 and the test tube opening 2 have sufficient connection length, making the tube sleeve 42 less likely to fall off accidentally.

[0026] To further clarify, the auxiliary sleeve 43 and the nozzle sleeve 42 are at the same height.

[0027] To further explain, the longitudinal section of the support block 45 is acute-angled, allowing the swab to be broken more effectively through the sharp support block 45.

[0028] The working principle is as follows:

[0029] First, insert the tube sleeve 42 into the test tube opening 2. At this time, the tube sleeve 42 will be locked inside the test tube opening 2 by the connecting strap 41 and will not fall down into the test tube body 1.

[0030] Second, after the swab has collected the medical sample, it is inserted into the test tube body 1 through the test tube opening 2. When it is necessary to break off the excess length of the swab, the swab is moved into the auxiliary sleeve 43 through the opening 44 and bent forward. At this time, the rear part of the swab abuts against the auxiliary sleeve 43, and the front part of the swab abuts against the support block 45, which can provide two points of force for the swab (see reference). Figure 6 This ensures that the swab can be broken quickly, and the support block 45 is acute-angled, allowing the swab to be broken more effectively through the sharp support block 45.

[0031] Third, after the swab is broken, the tube sleeve 42 is removed from the inside of the test tube opening 2, and then the test tube cap 3 is screwed onto the outside of the test tube opening 2, thus completing the swab collection. The auxiliary breaking mechanism 4 does not change the internal shape of the test tube opening 2 and does not affect the subsequent removal of the contents of the test tube body 1.

[0032] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
