Detailed Description

The following description of the technical solutions in the embodiments of the present application will be made with reference to the drawings in the embodiments of the present application, and it is apparent that the described embodiments are only some embodiments of the present application, but not all embodiments.

Hereinafter, the terms "first," "second," and the like are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defining "a first", "a second", etc. may explicitly or implicitly include one or more such feature.

Furthermore, in this application, the terms "upper," "lower," "horizontal," and "vertical" are defined relative to the orientation in which the components in the figures are schematically disposed, and it should be understood that these directional terms are relative concepts, which are used for descriptive and clarity relative thereto, and which may be varied accordingly with respect to the orientation in which the components in the figures are disposed.

In the present application, unless explicitly specified and limited otherwise, the term "coupled" is to be construed broadly, and for example, "coupled" may be either fixedly coupled, detachably coupled, or integrally formed; can be directly connected or indirectly connected through an intermediate medium.

In the prior art, as shown in fig. 1, a cap portion of a sample container is designed with a sealing cap and a cap lock for locking the sealing cap. As shown in fig. 2, since the cover lock is located in the connection portion of the sampling assembly and the sample container, the cover lock has a force pushing against the sampling assembly when the sample container is connected to the sampling assembly, reducing the tightness of the connection between the sample container and the sampling assembly. On the other hand, the cover lock is easy to deform and damage under the action of the pushing force of the sampling assembly. In addition, the root position of the sealing cap also has a blocking effect on the connection of the sampling assembly.

In order to improve the connection tightness between the sample container and the sampling assembly, the present application provides a sampling assembly 100, as shown in fig. 3, where the sampling assembly 100 can be used in combination with an endoscope having an extraction tube, such as a gastroscope, enteroscope, cystoscope, thoracoscope, etc., for extracting pathological effusion from human body parts, such as thoracic cavity, abdominal cavity, pelvic cavity, etc. The sampling assembly 100 can also be used with other detection devices, such as medical devices including ventilators, ultrasonic detectors, and the like. Alternatively, the sampling assembly 100 may be directly connected to an extraction conduit for extracting pathological fluid. The specific application scenario of the sampling device is not particularly limited.

Specifically, as shown in fig. 3, the sampling assembly 100 may include a sampling assembly 30 and a sample container 40. Wherein the sampling assembly 30 may include a sampling valve (not shown) for controlling the flow state of the pathological effusion. A negative pressure interface 31 and an operating knob 32 may also be provided on the sampling assembly 30. The negative pressure interface 31 may be connected to a negative pressure device for sucking pathological effusion. The knob 32 is operated to facilitate rotation of the sampling valve. In some embodiments, the negative pressure interface 31 and the operation knob 32 may be provided at left and right sides of the sampling assembly 30, respectively.

On this basis, as shown in fig. 3, the sample container 40 may include a sampling cap 10 and a sampling container 20. As shown in connection with fig. 4, the sampling vessel 20 may be detachably connected to the sampling cap 10 from the bottom of the sampling cap 10. The detachable connection mode includes but is not limited to a threaded connection mode or a snap connection mode.

To better illustrate the structure of the sampling cap 10, as shown in fig. 5, the sampling cap 10 may include a cap body 11 and a cover plate 12. A sampling inlet 13 may be provided at the front end of the cover 11, for communicating with the sampling assembly 30 and receiving pathological effusion from the sampling assembly 30. A sampling outlet 14 may be provided at the bottom of the cap 11 for communicating with a sampling container 20 for collecting pathological liquid. The sampling inlet 13 communicates with the sampling outlet 14 within the cover 11.

In some embodiments, as shown in fig. 5, a docking surface 15 may be further disposed at the front end of the cover 11, the sampling inlet 13 may be disposed within the docking surface 15, and the cover 12 may be connected outside the docking surface 15. For example, the cover plate 12 may be disposed on top of the cover 11.

In this way, the cover plate 12 outside the range of the abutting surface 15 does not affect the connection between the sampling assembly 30 and the cover body 11 at all, thereby ensuring that the sampling assembly 30 and the sample container 40 can be completely attached. Compared with the prior art, the sealing cover, the cover lock and other parts are not clamped between the sampling assembly 30 and the sample container 40, so that the stability of connection between the sampling assembly 30 and the sample container 40 is ensured.

In addition, since the negative pressure port 31 and the operation knob 32 are provided at both left and right sides (shown in fig. 3) of the sampling assembly 30, respectively, the cover plate 12 is provided at the top of the cover body 11 such that the cover plate 12 does not block the connection of the negative pressure port 31 in the opening or closing direction. Also, the cover plate 12 does not affect the rotation of the operation knob 32 in the opening or closing direction as well. Of course, since no other knob or interface is provided at the top and bottom of the sampling assembly 30, the cover 12 may be provided at the bottom of the cover 11.

In order to enable the sample container 40 to be mounted on the sampling assembly 30 during sampling, a stopper 16 may be provided on the cover 11 as shown in fig. 5 and 6. Stop 16 may include a web 161 and a web 162, and a connector 163 may be provided at an end of web 161 adjacent to sampling assembly 30. One end of the connecting rib 162 may be connected to the cover 11, and the other end of the connecting rib 162 may be connected to the middle of the connecting plate 161. Thus, the connection plate 161 can swing slightly around the connection rib 162.

Accordingly, as shown in fig. 7, a connection portion 33 may be provided on the sampling assembly 30. In sampling, the interface 15 (shown in FIG. 5) on the sample container 40 is first brought into engagement with the sampling assembly 30. Then, the sample container 40 is connected to the sampling assembly 30 by connecting the connecting member 163 to the connecting portion 33.

In some embodiments, as shown in fig. 5 and 6, two sets of stops 16 may be provided on the cover 11 in order to enhance the strength of the connection between the sampling assembly 30 and the sample container 40. Also, in order not to interfere with the connection between the sampling assembly 30 and the sample container 40, two sets of stops 16 are provided on either side of the cover 11, outside the extent of the abutment surface 15. In this way, the sampling unit 30 and the sample container 40 have the connection points on both sides, and the problem of easy relative shaking between the sampling unit 30 and the sample container 40 can be avoided when only one-sided connection points are provided.

On this basis, as shown in fig. 6, the connection member 163 may be provided as an inwardly protruding claw. As shown in fig. 7, the connection portion 33 may be provided as an outwardly protruding limit socket. During sampling, after the sample container 40 is in butt joint with the sampling assembly 30, the clamping claw can slide relative to the limiting clamping seat, and the clamping claw is finally clamped with the limiting clamping seat firmly, so that the sample container 40 is connected to the sampling assembly 30.

After the sampling is completed, the connecting plate 161 can swing slightly around the connecting ribs 162, and the clamping jaw can be separated from the limiting clamping seat only by slightly pressing the other end of the connecting plate 161, so that the sample container 40 is detached from the sampling assembly 30, and the operation is simple and convenient.

It will be appreciated that the connector 163 may also be provided as an outwardly projecting limit stop and the connector 33 as an inwardly projecting catch. Of course, other connection structures such as a plug and a socket, etc. may be provided for the connection member 163 and the connection portion 33, and the specific structure of the connection member 163 and the connection portion 33 is not particularly limited in this application.

In addition, as shown in fig. 8, the sampling cap 10 provided in the present application may also eliminate the design of the connection rib 162. The connection plate 161 may be directly connected to the cover 11. At this time, the length of the connection plate 161 protruding from the cover 11 may be correspondingly increased. Meanwhile, a pulling-up portion 164 may be provided at a position of the connection plate 161 near the connection piece 163, and the pulling-up portion 164 may be provided outside the connection plate 161.

During sampling, the sample container 40 can be connected to the sampling assembly 30 by utilizing the structural elasticity of the connecting plate 161 and the cooperation of the clamping claw and the limiting clamping seat. After sampling is completed, the sample container 40 can be removed from the sampling assembly 30 by pulling the pull-up portion 164 outwardly to disengage the jaws from the stop collar.

In order to better lock the cover plate 12, as shown in fig. 9, locking pieces 121 protruding out of the plane of the cover plate 12 may be disposed at two sides of the cover plate 12, and the locking pieces 121 may be designed as a limiting seat. Of course, the lock member 121 may be replaced by increasing the planar size of the cover plate 12. As shown in fig. 5, when the cover plate 12 rotates to the position of the sampling inlet 13, the claw can slide relative to the locking piece 121, and the claw is finally clamped with the locking piece 121 firmly, so that the cover plate 12 is locked at the position of the sampling inlet 13.

When the cover plate 12 needs to be opened, the cover plate 12 can be unlocked only by slightly pressing the other end of the connecting plate 161 as the connecting plate 161 can swing slightly around the connecting ribs 162, so that the cover plate 12 is opened. Of course, other connection structures such as a plug and a socket, in which the connection member 163 and the locking member 121 are in plug-in fit, may be provided, and the specific structures of the connection member 163 and the locking member 121 are not particularly limited in this application.

Compared with the sampling cover in the prior art, the sampling cover can be connected with the sampling assembly 30 and can lock the cover plate 12 through the locking opening of the stop part 16 on the cover body 11. Because the sealing cover in the prior art is locked through the cover lock, and the cover lock is an open type locking port, a user cannot open the sealing cover by one hand.

The cover plate 12 is arranged at the top of the cover body 11, and the cover plate 12 can be unlocked only by slightly pressing the connecting plate 161 with the thumb and the index finger, so that the function of opening and closing the cover plate 12 by one hand is realized. Thus, the operation of opening the cover plate 12 and connecting the sampling assembly 30 is simpler and more convenient.

In order to better connect the sample container 40 with the sampling assembly 30, as shown in fig. 5 and 7, a first plugging portion 34 may be further disposed at an end of the sampling assembly 30 facing the cover 11, and a second plugging portion 151 may be disposed at an end of the abutting surface 15 on the cover 11 facing the sampling assembly 30. The cover 11 is mounted on the sampling assembly 30 through the plug-in fit of the second plug-in portion 151 and the first plug-in portion 34.

For example, as shown in fig. 7, the first plug-in portion 34 may be designed as an annular step protruding from the end face of the sampling assembly 30. As shown in fig. 5, the second plug 151 may be designed as a countersunk structure on the abutment surface 15. After the sample container 40 is docked with the sampling assembly 30, the sample container 40 can also be mounted on the sampling assembly 30 through the insertion of the counter bore structure and the annular step, so that the connection strength between the sample container 40 and the sampling assembly 30 is improved.

In addition, as shown in fig. 5 and 7, in order to prevent the sample container 40 from rotating relative to the sampling assembly 30 after being connected, the sampling inlet 13 may be designed to have a waist shape, an oval shape, or the like. Meanwhile, a connection nozzle 35 protruding from the sampling assembly 30 may be provided on the sampling assembly 30. The shape of the connecting nozzle 35 matches the shape of the sampling inlet 13. The insertion of the connector 35 into the sampling inlet 13 prevents relative rotation between the sample container 40 and the sampling assembly 30 when the sample container 40 is connected to the sampling assembly 30.

Correspondingly, as shown in fig. 9, a pillar 122 protruding from the plane of the cover plate 12 may also be provided on the cover plate 12. After the cover plate 12 is locked on the abutting surface 15, the cover plate 12 can be further plugged and covered on the cover body 11 through the columnar portion 122 and the counter bore structure, so that not only can the connection strength between the cover plate 12 and the cover body 11 be improved, but also the sealing performance between the cover plate 12 and the cover body 11 can be improved.

The foregoing is merely specific embodiments of the present application, but the scope of the present application is not limited thereto, and any person skilled in the art can easily think about changes or substitutions within the technical scope of the present application, and the changes and substitutions are intended to be covered by the scope of the present application. Therefore, the protection scope of the present application shall be subject to the protection scope of the claims.
