Description

Technical Field

[0001] This utility model relates to the field of sampling test tube technology, and in particular to a gynecological vaginal secretion sampling test tube. Background Technology

[0002] Vaginal secretion examination is one of the most common gynecological examinations, used to determine the presence and cause of vaginal inflammation, providing a basis for clinical treatment. Currently, clinicians use saline-moistened cotton swabs to collect vaginal secretions. The collected specimen is immersed in a glass test tube containing 1-2 ml of saline, which is then sent by the patient to the laboratory for testing. During testing, medical staff need to remove the cotton swab, place it into the instrument's tubing, add saline, mix well, and finally remove the swab for testing. However, in practice, it has been found that due to the uneven distribution of secretions in the vagina and cervix, using cotton swabs for collection may be inaccurate, affecting the accuracy of the results. Moreover, the cotton swab becomes larger after being moistened, and secretions may contaminate the outer wall of the glass tube, causing hand contamination for the personnel handling it. In addition, the open state of the glass tube makes it easy for secretions to spill and contaminate the sample during patient delivery. When performing tests, medical staff need to take an extra step: remove the swab into a special test tube, mix it with saline solution, and then put it back into a glass test tube. This process also produces an unpleasant odor in the air, polluting the environment and causing secondary contamination and dilution of the sample, which affects the accuracy of the test results and causes inconvenience to medical staff.

[0003] The purpose of this invention is to provide a gynecological vaginal secretion sampling tube, which aims to solve the problems existing in the use of the sampling tube in the above-mentioned technical problems, so as to improve the practicality of the sampling tube, improve the convenience of sampling, and improve the accuracy of the results.

[0004] The technical solution adopted in this utility model is as follows:

[0005] Gynecological vaginal secretion sampling tube, including

[0006] tube body;

[0007] A cap, which is provided over the opening of the pipe body;

[0008] A straw, mounted on the cap and extending into the tube body;

[0009] A sampling cotton ball is placed at the opening of the straw and is used for wiping and sampling.

[0010] The tube body is provided with a squeezing part, which is assembled such that when the squeezing part is pressed, the inner wall of the tube body can be squeezed and bonded to the sampling cotton body.

[0011] This utility model also has the following technical features:

[0012] In one embodiment of this utility model, the straw is made of rigid plastic, one end of the straw extends out of the cap, and a pressing body is provided at the end of the straw extending out of the cap.

[0013] In one embodiment of this utility model, the sampling cotton body is tubular in shape and is sleeved at the opening of the suction tube.

[0020] In one embodiment of this utility model, the air guide tube is located between the inner wall of the through tube and the outer wall of the suction tube.

[0021] Compared with existing technologies, the beneficial effects of this utility model are as follows: In actual use, a certain amount of physiological saline is pre-introduced into the tube. The secretions are sampled by the sampling cotton body set at the pipette opening on the cap. After sampling, the cap is directly placed on the tube body, and the tube body is deformed by pressing the squeezing part, thereby squeezing and bonding the inner wall of the tube body with the sampling cotton body. This allows the secretions on the sampling cotton body to be fully dissolved in the physiological saline. When using the device, the cap is removed, and the sample liquid can be transferred to the test tube of the detection equipment through the pipette, thus avoiding sample spillage. Moreover, the detection uses the undiluted solution. Therefore, this sampling tube can avoid the problems of contamination and spillage during the entire operation, ensuring the accuracy of the results, and also improving the convenience of sampling and detection operations.

[0029] The following specific examples illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model.

[0030] It should be noted that the illustrations provided in this embodiment are only schematic representations of the basic concept of this utility model. Therefore, the drawings only show the components related to this utility model and are not drawn according to the actual number, shape and size of the components. In actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0031] It should be noted that, due to the uneven distribution of secretions in the vagina and cervix, the use of cotton swabs for collection may result in inaccurate collection and affect the accuracy of the results. Moreover, the cotton swab becomes larger after being wetted, and the secretions may contaminate the outer wall of the glass tube, causing contamination of the hands of the person handling it. In addition, the open state of the glass tube makes it easy for secretions to spill out and contaminate the patient during the sample delivery process. During machine testing, medical staff need to take an extra step: remove the cotton swab into a special tube, mix it with saline solution, and then put it back into a glass test tube. This process also produces an unpleasant odor, polluting the environment and causing secondary contamination and dilution of the sample, affecting the sensitivity of the test results and causing inconvenience to medical staff. To address this, this utility model proposes a gynecological vaginal secretion sampling test tube, including a tube body 10; a cap 20, which covers the opening of the tube body 10; a pipette 30, which is installed on the cap 20 and extends into the tube body 10; and a sampling cotton 40, which is located at the opening of the pipette 30 and is used for wiping and sampling. The tube body 10 is provided with a squeezing part, which is assembled such that when the squeezing part is pressed, the inner wall of the tube body 10 is squeezed and bonded to the sampling cotton 40.

[0032] In one embodiment, see Figure 6 and Figure 8 The sampling cotton body 40 is made of a relatively soft sponge, which increases the avoidance of roughness and ensures that when the sampling cotton body 40 comes into contact with the secretion, the secretion can effectively adhere to the sampling cotton body 40, thus ensuring the effectiveness of the sampling.

[0033] In one embodiment, the tube body 10 is made of flexible plastic, and the extrusion part includes a variable diameter tube 11 disposed at the bottom of the tube body 10. The outer diameter of the variable diameter tube 11 gradually decreases from the connection end with the tube body 10 to the bottom of the tube. When the suction tube 30 is inserted into the tube body 10, the sampling cotton body 40 is located at the opening of the variable diameter tube 11.

[0034] In one embodiment, after the patient has taken a sample, the pipette 30 is inserted into the tube body 10, and the cap 20 is placed on the opening of the tube body 10. By pressing the position of the reducing tube 11, the tube body 20 is deformed, thereby pressing the sampling cotton 40, so that the secretions on the sampling cotton 40 can be fully dissolved in the saline solution. By pressing, the secretions and saline solution can be fused together. Shaking and other operations can be used to ensure the reliability of the fusion and the accuracy of the subsequent results.

[0035] In one embodiment, the pipette 30 may be provided with a fragile part, which may be a notch formed on the outer wall of the pipette 30. After the sampling cotton 40 takes a sample and is placed in the tube 10, medical personnel can operate the squeezing part to make the secretions on the sampling cotton 40 fully dissolve in the saline solution. The squeezing pressure can be increased to break the fragile part, so that the sampling cotton 40 remains in the tube 10. The pipette 30 can then be pulled out of the tube 10, and the mixed sample solution can be dripped into the test tube for testing. This avoids the contamination problem caused by the droplets falling from the sampling cotton 40.

[0036] In one embodiment, the straw 30 is made of rigid plastic, one end of the straw 30 extends out of the cap 20, and a pressing body 31 is provided at the end of the straw 30 extending out of the cap 20.

[0037] By squeezing and pressing body 31, see reference. Figure 2 The operable pipette 30 adsorbs the sample liquid inside the tube body 10, thereby transferring the sample liquid inside the tube body 10 to the glass test tube used in the testing equipment, avoiding the pollution problem caused by the spillage of the sample liquid.

[0038] In one embodiment, to ensure the reliability of the installation between the sampling cotton body 40 and the straw 30 and to prevent the sampling cotton body 40 from falling out of the opening of the straw 30, the sampling cotton body 40 is tubular in shape and is fitted onto the opening of the straw 30.

[0039] In one embodiment, see Figure 7 and Figure 8 The outer wall of the tube opening of the straw 30 is provided with an annular protrusion 33, and the inner wall of the sampling cotton body 40 is provided with an annular groove 41 that cooperates with the annular protrusion 33. The tube opening of the straw 30 protrudes out of one end of the sampling cotton body 40.

[0040] In one embodiment, see Figure 2To ensure a proper fit between the tube opening of the tube body 10 and the cap 20, to prevent the cap 20 from falling out of the tube opening of the tube body 10, and to prevent the sample liquid from leaking out of the gap between the cap 20 and the tube body 10, the tube opening of the tube body 10 is provided with a connector 12. The outer wall of the connector 12 is provided with a connector protrusion 121. The cap 20 is provided with a connector annular groove 21. The connector 12 is inserted into the connector annular groove 21, and the connector protrusion 121 abuts against the groove wall of the connector annular groove 21.

[0041] In one embodiment, the insertion protrusion 121 is made of flexible material and two sets are arranged at intervals. When the cap 20 is placed on the pipe opening of the tube body 10, the insertion tube 12 is inserted into the insertion annular groove 21, and the insertion protrusion 121 abuts against the groove wall of the insertion annular groove 21, causing the insertion protrusion 121 to deform, so as to ensure a seal between the pipe opening of the tube body 10 and the cap 20. When it is necessary to remove the cap 20 from the tube body 10, the cap 20 can be easily pulled off from the pipe opening of the tube body 10.

[0042] In one embodiment, to ensure the installation between the straw 30 and the cap 20, the cap 20 is provided with a snap-fit ​​annular groove 22 at the bottom position, and the straw 30 is provided with a fixing insertion tube 32 on the tube wall, which is inserted into the snap-fit ​​annular groove 22.

[0043] In one embodiment, the outer diameter of the snap-fit ​​annular groove 22 is slightly smaller than the outer diameter of the fixed insertion tube 32. When the fixed insertion tube 32 is inserted into the snap-fit ​​annular groove 22, the straw 30 and the cap 20 can be reliably installed by the deformation of the snap-fit ​​annular groove 22.

[0044] In one embodiment, see Figure 2 To ensure the installation between the pressing body 31 and the cap 20, the bottom of the cap 20 is provided with a through tube 23 for the straw 30 to pass through. The pressing body 31 includes an air guide tube 311, and the air guide tube 311 and the tube end of the straw 30 form an insertion fit.

[0045] In one embodiment, see Figure 2 The pressing body 31 is made of flexible plastic. A pressing chamber is provided inside the pressing body 31, and the pressing chamber is connected to the air guide tube 311. A recessed area 312 is provided on the outside of the pressing body 31 to facilitate the user's finger pressing operation.

[0046] By pressing the recessed area 312, a negative pressure is formed on the pressing body 31, which allows the sample liquid in the tube 10 to be drawn through the pipette 30 and transferred to the glass test tube. Pressing the recessed area 312 can drip the sample liquid in the pipette 30 into the glass test tube.

[0047] To ensure a seal between the air guide tube 311 and the through tube 23, the air guide tube 311 is located between the inner wall of the through tube 23 and the outer wall of the suction tube 30.

[0048] In summary, when using this sampling tube, a certain amount of physiological saline is pre-introduced into the tube body 10. Secretions are sampled using the sampling cotton 40 located at the opening of the pipette 30 on the cap 20. After sampling, the cap 20 is directly placed on the tube body 10, and the tube body 10 is deformed by pressing the squeezing part, causing the inner wall of the tube body 10 to press and bond with the sampling cotton 40. This allows the secretions on the sampling cotton 40 to fully dissolve in the physiological saline. When using the device, the cap 20 is removed, and the sample solution can be transferred to the glass test tube of the testing equipment using the pipette 30, thus preventing spillage. Therefore, this sampling tube avoids contamination problems, improves the convenience of sampling and testing operations, and ensures the accuracy of the results.

[0049] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0050] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
