Description

Technical Field

[0001] The utility model relates to the technical field of test tubes, in particular to a collection test tube which is easy to operate. Background Art

[0002] The collection of nasopharyngeal pathogens to detect various respiratory diseases is widely used clinically. During collection, a cotton swab is first used to collect pathogens in the patient's nasal cavity or throat, and then the head of the cotton swab is inserted into a collection test tube, and the head of the cotton swab is broken off and placed in the test tube to preserve the nucleic acid sample. When the medical staff breaks the cotton swab, they use a test tube and a test tube cap to clamp the head of the swab and then break it off. Since the mouth of the test tube is smooth and the swab cannot be fixed, the swab is easy to slip and fall out of the test tube, causing inconvenience to the sampling work. In addition, when breaking off the head of the swab, there will inevitably be shaking at the moment of breaking. At this time, some pathogens on the head of the swab may bounce from the mouth of the test tube to the surface of objects, the air, the skin and mucous membranes of medical staff, or the mask, which will increase the risk of pathogen transmission and the risk of infection for medical staff.

[0003] For example, the patent with announcement number CN220385099U announces a nucleic acid collection tube that prevents finger contamination, including a tube body with an open structure at one end and a tube cap detachably connected to the open end of the tube body; the open end of the tube body is provided with a plurality of slots to allow the sampling swab to pass through, and the inner side of the tube body is integrally formed with a splash-proof ring near the open end; the top of the tube cap is provided with a cross handle for turning the tube cap. The structure is simple, easy to use, and easy to break the swab. When the swab is broken, it is not easy to splash out of the collection tube. The knob is convenient to turn, and the knob is far away from the tube mouth, which can reduce the risk of samples being contaminated by the fingers of medical staff, reduce the burden on medical staff, and improve sampling efficiency.

[0004] However, the collection tube in the above technology still has the following problems:

[0005] Although the splash-proof ring can prevent the swab from flying out of the collection tube when it breaks, when the swab head is inserted into the test tube, it will first touch the splash-proof ring, causing some pathogens to adhere to the top of the splash-proof ring. When the swab is broken, the shaking of the swab is transmitted to the splash-proof ring, causing the pathogens on the splash-proof ring to splash upward out of the test tube mouth, and there is still a large risk of infection. Utility Model Content

[0006] In view of the deficiencies in the prior art, the utility model provides an easy-to-operate collection test tube. For example, when the test tube cover is closed, the cotton swab can be broken so that the splashed pathogens are blocked in the test tube by the test tube cover, thereby reducing the spread of pathogens and reducing the risk of collection infection.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an easy-to-operate collection test tube, comprising a test tube body, an outer wall of the test tube body near one end of the test tube mouth is fixedly connected to a tube mouth ring, a test tube cover is hinged on the upper surface of the tube mouth ring, the inner wall of the test tube cover is slidably connected to the outer wall of the test tube body near one end of the test tube mouth, the test tube cover and the tube mouth ring are abutted against each other, a swab groove is provided at one end of the test tube body near the test tube cover, and a breaking assembly is connected to the inner wall of the test tube body near one end of the swab groove.

[0008] Furthermore, the breaking assembly includes a connecting rod and a barb, one end of the connecting rod is fixedly connected to the inner wall of the test tube body, and the other end of the connecting rod is fixedly connected to the barb, and the opening of the barb is located below the side of the swab groove.

[0009] Furthermore, the bottom of the swab groove is located above the nozzle ring.

[0010] Furthermore, an inner sealing ring is fixedly connected to the inner wall of the test tube cover, and an outer wall of the inner sealing ring is slidably connected to the inner wall of the test tube body.

[0011] Furthermore, a matching groove is formed at one end of the inner sealing ring away from the test tube cover, and the matching groove is matched with the swab groove.

[0012] Furthermore, an annular sliding groove is formed on the inner wall of the tube mouth ring, and a convex ring is fixedly connected to the outer wall of the test tube body, and the convex ring is slidably connected to the annular sliding groove.

[0013] Furthermore, the number of the matching grooves is two, and the two matching grooves are symmetrically arranged.

[0014] Furthermore, a cover opening block is fixedly connected to the outer wall of the test tube cover at one end away from the test tube body.

[0015] Compared with the prior art, the utility model has the following beneficial effects:

[0016] This easy-to-operate collection test tube can fix the head of the swab by arranging a breaking component in the test tube. When the test tube cover is covered on the test tube, the breaking component is used to squeeze and break the swab head in the test tube and the swab handle on the outside, so that when the swab head is broken, the test tube cover is already covered on the test tube, preventing pathogens splashed during the break from spreading outside the test tube, thereby improving the safety of collecting pathogens and reducing the risk of infection.

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0024] See also Figure 1 - Figure 5 A collection test tube that is easy to operate comprises a test tube body 1, wherein the outer wall of the test tube body 1 near the test tube mouth is fixedly connected with a tube mouth ring 2, the upper surface of the tube mouth ring 2 is hinged with a test tube cover 3, the inner wall of the test tube cover 3 is slidably connected with the outer wall of the test tube body 1 near the test tube mouth, the test tube cover 3 abuts against the tube mouth ring 2, a swab groove 101 is provided at one end of the test tube body 1 near the test tube cover 3, and a breaking component is connected to the inner wall of the test tube body 1 near the swab groove 101.

[0025] like Figure 1 - Figure 5 As shown, the easy-to-operate collection tube in the utility model is similar to the existing easy-to-operate collection tube structure, such as a finger-proof nucleic acid collection tube disclosed in patent announcement number CN220385099U. The main improvement of the utility model is that it can improve the safety of collectors when collecting pathogens and reduce the risk of infection. Figures 1 to 5 As shown, when the collection tube of the utility model is used, the test tube cover 3 is flipped out from the test tube body 1, and then the swab head that has collected the pathogen is inserted into the test tube body 1, and the swab head end is aligned with the section 1. BreakThe components are connected, and the swab handle is placed in the swab groove 101. The test tube cover 3 is then turned over and covered on the test tube mouth of the test tube body 1. By pressing the test tube cover 3, the edge of the test tube cover 3 presses the swab handle at the position of the swab groove 101 downward, and cooperates with the internal breaking component to break the head of the swab inside the test tube body 1. When the swab head is broken, the shaking and splashing pathogens are blocked by the test tube cover 3 inside the test tube body 1, reducing the risk of infection for pathogen collectors. The test tube cover 3 and the tube mouth ring 2 are hinged and fixed by an elastic sheet.

[0026] like Figure 2 - Figure 5 As shown, the breaking assembly includes a connecting rod 4 and a barb 5, one end of the connecting rod 4 is fixedly connected to the inner wall of the test tube body 1, and the other end of the connecting rod 4 is fixedly connected to the barb 5, and the opening of the barb 5 is located at the lower side of the swab groove 101. The head end of the swab is clamped in the barb 5 from the lower opening of the barb 5, and the connecting rod 4 allows a certain distance between the barb 5 and the swab groove 101, so that the swab can maintain a certain inclination angle between the barb 5 and the swab groove 101. When the test tube cover 3 is covered on the test tube body 1, the edge of the test tube cover 3 is gradually pressed down, thereby pressing down the swab handle in the swab groove 101, and the swab handle is bent and broken in cooperation with the barb 5.

[0027] like Figure 2 - Figure 5 As shown, the bottom of the swab groove 101 is located above the tube orifice ring 2. The swab groove 101 is arranged above the tube orifice ring 2, so that when the test tube cover 3 is pressed down, the swab handle can be bent downward and broken.

[0028] like Figure 2 - Figure 4 As shown, the inner wall of the test tube cover 3 is fixedly connected with an inner sealing ring 6, and the outer wall of the inner sealing ring 6 is slidably connected to the inner wall of the test tube body 1. When the test tube cover 3 is covered on the test tube body 1, the inner sealing ring 6 is connected to the inner wall of the test tube body 1, which can further improve the sealing effect of the test tube body 1.

[0029] like Figure 2 - Figure 4 As shown, the inner sealing ring 6 is provided with a matching groove 601 at one end away from the test tube cover 3, and the matching groove 601 is matched with the swab groove 101. When the test tube cover 3 is covered on the test tube body 1, the matching groove 601 of the inner sealing ring 6 can prevent the inner sealing ring 6 from bending the swab downward, causing the swab to be separated from the barb 5.

[0030] like Figure 4 and Figure 5As shown, the inner wall of the nozzle ring 2 is provided with an annular groove 201, and the outer wall of the test tube body 1 is fixedly connected with a convex ring 7, which is slidably connected with the annular groove 201. Through the connection between the convex ring 7 and the annular groove 201, the test tube cover 3 can be rotated on the test tube body 1 through the nozzle ring 2. After the swab is broken, the test tube cover 3 can be rotated to displace the swab groove 101 and the matching groove 601 on the inner sealing ring 6, thereby further improving the sealing effect of the test tube cover 3 on the test tube body 1.

[0031] like Figure 2 - Figure 4 As shown, there are two matching grooves 601, and the two matching grooves 601 are symmetrically arranged. By arranging two symmetrical matching grooves 601 on the inner sealing ring 6, the swab groove 101 can be rotated to the left or right side of the test tube cover 3 by rotating the test tube cover 3, so that people with different hand habits can use the collection test tube conveniently, and the two matching grooves 601 can be used in coordination with left and right rotation.

[0032] like Figure 1 - Figure 4 As shown, the outer wall of the test tube cover 3 away from the end of the test tube body 1 is fixedly connected with a cover opening block 8. The cover opening block 8 is arranged on the test tube cover 3, so that when opening the test tube cover 3, the test tube cover 3 can be opened more easily through the cover opening block 8.

[0033] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that many changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention.
