Description

Technical Field

[0001] This application relates to the field of medical device technology, and in particular to a sampling cap, sample container and sampling device. Background Technology

[0002] Sample containers are commonly used to collect pathological fluids such as sputum, gastric juice, and urine from the human body. During sampling, the sample container needs to be attached to the sampling assembly. After sampling, the sample container needs to be detached from the sampling assembly and sealed.

[0003] In patent CN110520059B, such as Figure 1 and Figure 2 As shown, the sample container has a sealing cap and a locking mechanism at the edge of the sampling port. A separate latch handle for connecting the sampling assembly is also located at the top of the cap. This necessitates the use of two locking mechanisms in the cap; otherwise, the sealing cap cannot be closed, or the sample container cannot be connected to the sampling assembly. Furthermore, because the locking mechanism is an open-hole design, users must pry open the sealing cap with their fingernails or pry open the locking mechanism, which is not only inconvenient but also prone to damaging the locking mechanism. Summary of the Invention

[0004] This application provides a sampling cap, a sample container, and a sampling device to solve, or at least partially solve, the technical problem of needing to simultaneously set two locking mechanisms on the cap portion.

[0005] To achieve the above objectives, this application adopts the following technical solution:

[0006] A first aspect of this application provides a sampling cover, which is installed on a sampling container and can be connected to a sampling assembly. The sampling cover includes a cover body and a cover plate. The cover body has a sampling inlet for communicating with the sampling assembly and a sampling outlet for communicating with the sampling container. A stop portion is provided on the cover body. The cover plate is connected to the cover body and can seal the sampling inlet position. The cover plate can be locked at the sampling inlet position by the stop portion. The sampling assembly is provided with a connecting portion for connecting with the stop portion, and the cover body can also be installed on the sampling assembly through the connection between the stop portion and the connecting portion.

[0007] In some embodiments, two sets of stops are provided on the side of the cover, respectively located on both sides of the sampling inlet. Connecting parts are provided on both sides of the sampling assembly, and the two sets of stops can be connected to both sides of the sampling assembly.

[0008] In some embodiments, the stop includes a connecting plate disposed on the cover, and a connector is disposed at one end of the connecting plate near the sampling component, the connector being connectable to the cover or the sampling component.

[0009] In some embodiments, the stop part further includes a connecting rib provided on the cover, the connecting plate is connected to the connecting rib, and the connecting plate can rotate around the connecting rib to the position where the connector is locked or opened.

[0010] In some embodiments, one of the connecting part and the connecting member is a limiting seat, and the other of the connecting part and the connecting member is an inwardly protruding claw.

[0011] In some embodiments, the cover plate is provided with a locking element for connection with the stop. The cover plate can seal the sampling inlet by connecting the locking element to the stop.

[0012] A second aspect of this application provides a sample container, including the sampling cap and sampling container described above, with the sampling container connected to the sampling cap. The sampling cap in the sample container described above has the same technical effects as the sampling cap provided in the foregoing embodiments, and will not be repeated here.

[0013] A third aspect of this application provides a sampling device, including a sampling component and the sample container described above, wherein the sample container can be mounted on the sampling component. The sample container involved in the above sampling device has the same technical effects as the sample container provided in the foregoing embodiments, and will not be described again here.

[0014] In some implementations, the sampling component is provided with a negative pressure interface and an operating knob, and the opening or closing direction of the cover avoids the negative pressure interface and the operating knob.

[0015] In some embodiments, the sampling component is provided with a first insertion part, and the cover is provided with a mating surface on the side facing the sampling component. The mating surface is provided with a second insertion part, and the cover is installed on the sampling component through the insertion and engagement of the second insertion part and the first insertion part.

[0016] Compared with the prior art, this application has the following advantages:

[0017] During sampling, the user can connect the stop on the cover to the connecting part on the sampling component, thereby installing the sample container on the sampling device. After sampling, the user can remove the sample container and lock the cover at the sampling inlet position using the stop, thus sealing the sample container. This application, through the locking mechanism of the stop on the cover, can both connect the sampling component and lock the cover, greatly simplifying the structure of the cap.

Detailed Implementation

[0029] The technical solutions of the embodiments of this application will be described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0030] Hereinafter, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature.

[0031] Furthermore, in this application, directional terms such as "upper," "lower," "horizontal," and "vertical" are defined relative to the indicated placement of the components in the accompanying drawings. It should be understood that these directional terms are relative concepts, used for relative description and clarification, and can change accordingly depending on the placement of the components in the accompanying drawings.

[0032] In this application, unless otherwise expressly specified and limited, the term "connection" shall be interpreted broadly. For example, "connection" may be a fixed connection, a detachable connection, or an integral part; it may be a direct connection or an indirect connection through an intermediate medium.

[0033] In existing technologies, such as Figure 1 As shown, during sampling, the sample container is connected to the sampling component (not shown in the figure) via the snap handle at the top of the cap. Figure 2 As shown, when the sample container needs to be closed after sampling, the locking head on the sealing cap engages with the cap lock at the edge of the sampling port, thus locking the sealing cap at the sampling port. This requires two locking structures on the cap to lock the sealing cap and connect the sampling components, which not only hinders structural simplification but also makes the sealing cap difficult to open.

[0034] This application provides a sampling device 100, such as... Figure 3 As shown, the sampling device 100 can be used in conjunction with endoscopes such as gastroscopes, colonoscopes, cystoscopes, and thoracoscopes, which have extraction tubes, to extract pathological effusions from the pleural cavity, abdominal cavity, pelvic cavity, and other parts of the human body. The sampling device 100 can also be used in conjunction with other testing equipment, such as ventilators and ultrasound scanners. Alternatively, the sampling device 100 can be directly connected to the extraction tube to extract pathological effusions. This application does not impose specific limitations on the specific application scenarios of the sampling device.

[0035] Specifically, such as Figure 3 As shown, the sampling device 100 may include a sampling component 30 and a sample container 40. The sampling component 30 may include a sampling valve (not shown) for controlling the flow of pathological effusion. A negative pressure port 31 and an operating knob 32 may also be provided on the sampling component 30. The negative pressure port 31 can be connected to a negative pressure device for aspirating pathological effusion. The operating knob 32 facilitates the rotation of the sampling valve. In some embodiments, the negative pressure port 31 and the operating knob 32 may be respectively located on the left and right sides of the sampling component 30.

[0036] Based on this, such as Figure 3 As shown, the sample container 40 may include a sampling cap 10 and a sampling container 20. (Combined with...) Figure 4As shown, the sampling container 20 can be detachably connected to the sampling cover 10 from the bottom. The detachable connection method includes, but is not limited to, threaded connection or snap-fit ​​connection.

[0037] To better demonstrate the structure of the sampling cover 10, such as Figure 5 As shown, the sampling cover 10 may include a cover body 11 and a cover plate 12. A sampling inlet 13 may be provided at the front end of the cover body 11 for communication with the sampling assembly 30 to receive pathological fluid extracted from the sampling assembly 30. A sampling outlet 14 may be provided at the bottom of the cover body 11 for communication with the sampling container 20 to collect pathological fluid. The sampling inlet 13 and the sampling outlet 14 are connected within the cover body 11.

[0038] In some implementations, such as Figure 5 As shown, a mating surface 15 can also be provided at the front end of the cover 11. The sampling inlet 13 can be opened within the range of the mating surface 15, and the cover plate 12 can be connected outside the range of the mating surface 15. For example, the cover plate 12 can be set at the top of the cover 11.

[0039] In this way, the cover plate 12 outside the mating surface 15 will not affect the connection between the sampling component 30 and the cover 11, thus ensuring a complete fit between the sampling component 30 and the sample container 40. Compared with the prior art, there are no sealing caps or other components such as cap locks sandwiched between the sampling component 30 and the sample container 40, ensuring the stability of the connection between the sampling component 30 and the sample container 40.

[0040] Furthermore, since the negative pressure port 31 and the operation knob 32 are respectively located on the left and right sides of the sampling assembly 30 ( Figure 3 As shown, the cover plate 12 is positioned on top of the cover body 11 so that it does not obstruct the connection of the negative pressure interface 31 in the opening or closing direction. Furthermore, the cover plate 12 does not affect the rotation of the operating knob 32 in the opening or closing direction. Of course, since no other knobs or interfaces are provided at the top or bottom of the sampling assembly 30, the cover plate 12 can also be positioned at the bottom of the cover body 11.

[0041] During sampling, in order for the sample container 40 to be mounted on the sampling component 30, such as Figure 5 and Figure 6 As shown, a stop portion 16 can be provided on the cover 11. The stop portion 16 may include a connecting plate 161 and a connecting rib 162, and a connector 163 may be provided at one end of the connecting plate 161 near the sampling assembly 30. One end of the connecting rib 162 can be connected to the cover 11, and the other end of the connecting rib 162 can be connected to the middle position of the connecting plate 161. In this way, the connecting plate 161 can rotate slightly around the connecting rib 162.

[0042] Correspondingly, such as Figure 7 As shown, a connecting part 33 can be provided on the sampling component 30. During sampling, the mating surface 15 on the sample container 40 is first connected. Figure 5 (As shown) is connected to the sampling component 30. Then, the sample container 40 can be connected to the sampling component 30 by connecting the connector 163 and the connecting part 33.

[0043] In some implementations, such as Figure 5 and Figure 6 As shown, to enhance the connection strength between the sampling component 30 and the sample container 40, two sets of stop portions 16 can be provided on the cover 11. Similarly, to avoid affecting the connection between the sampling component 30 and the sample container 40, the two sets of stop portions 16 are respectively located on both sides of the cover 11 and outside the mating surface 15. In this way, the sampling component 30 and the sample container 40 have connection points on both sides, avoiding the problem of relative wobbling between them when only one side has a connection point.

[0044] Based on this, such as Figure 6 As shown, connector 163 can be configured as an inwardly protruding claw. For example... Figure 7 As shown, the connecting part 33 can be configured as an outwardly protruding limiting seat. During sampling, after the sample container 40 is docked with the sampling component 30, the claw can slide relative to the limiting seat, and the claw will eventually be firmly engaged with the limiting seat, so that the sample container 40 is connected to the sampling component 30.

[0045] After sampling is completed, since the connecting plate 161 can rotate slightly around the connecting rib 162, you only need to press the other end of the connecting plate 161 gently to make the claw disengage from the limiting seat, thereby removing the sample container 40 from the sampling component 30. The operation is simple and convenient.

[0046] It is understandable that the connector 163 can also be configured as an outwardly protruding limiting seat, and the connecting part 33 can be configured as an inwardly protruding claw. Of course, the connector 163 and the connecting part 33 can also be configured as other connection structures such as plugs and sockets that fit together. This application does not impose any special limitations on the specific structure of the connector 163 and the connecting part 33.

[0047] In addition, such as Figure 8 As shown, the sampling cover 10 provided in this application can also eliminate the design of the connecting rib 162. Instead, the connecting plate 161 can be directly connected to the cover body 11. At this time, the length of the connecting plate 161 extending out of the cover body 11 can be increased accordingly. At the same time, a pull-up part 164 can be provided on the connecting plate 161 near the connector 163, and the pull-up part 164 is provided on the outside of the connecting plate 161.

[0048] During sampling, the structural elasticity of the connecting plate 161 can be utilized, and the sample container 40 can be connected to the sampling component 30 through the cooperation of the claws and the limiting seat. After sampling is completed, the claws can be disengaged from the limiting seat by pulling the pull-up part 164 outward, and the sample container 40 can be removed from the sampling component 30.

[0049] To better lock the cover plate 12, such as Figure 9 As shown, locking elements 121 protruding beyond the plane of the cover plate 12 can be provided on both sides of the cover plate 12. The locking elements 121 can also be designed as limiting brackets. Alternatively, the locking elements 121 can be replaced by increasing the planar dimensions of the cover plate 12. For example... Figure 5 As shown, when the cover plate 12 is rotated to the position of sealing the sampling inlet 13, the claw can slide relative to the locking member 121, and the claw is finally locked firmly with the locking member 121, so that the cover plate 12 is locked at the sampling inlet 13 position.

[0050] When it is necessary to open the cover plate 12, since the connecting plate 161 can rotate slightly around the connecting rib 162, simply pressing the other end of the connecting plate 161 will unlock the cover plate 12, thereby opening the cover plate 12. Of course, the connecting member 163 and the locking member 121 can also be configured as other connection structures such as plugs and sockets that engage in a plug-in fit. This application does not impose any special limitations on the specific structure of the connecting member 163 and the locking member 121.

[0051] Compared to the sampling cover in the prior art, this application not only connects the sampling component 30 but also locks the cover plate 12 through the locking port of the stop part 16 on the cover body 11. Because the sealing cover in the prior art is locked by a cover lock, and the cover lock is an open-hole type lock, the user cannot open the sealing cover with one hand.

[0052] In this application, the cover plate 12 is located on top of the cover body 11. The cover plate 12 can be unlocked by simply pressing the connecting plate 161 with the thumb and forefinger, realizing the function of opening and closing the cover plate 12 with one hand. Therefore, the operation of opening the cover plate 12 and connecting the sampling component 30 is simpler and more convenient in this application.

[0053] To better connect the sample container 40 to the sampling component 30, such as Figure 5 and Figure 7 As shown, a first insertion part 34 can also be provided at the end of the sampling component 30 facing the cover 11, and a second insertion part 151 can be provided at the end of the mating surface 15 on the cover 11 facing the sampling component 30. The cover 11 is then mounted on the sampling component 30 through the insertion and engagement of the second insertion part 151 and the first insertion part 34.

[0054] For example, such as Figure 7As shown, the first insertion portion 34 can be designed as an annular step protruding from the end face of the sampling component 30. For example... Figure 5 As shown, the second insertion part 151 can be designed as a countersunk hole structure on the mating surface 15. After the sample container 40 is mated with the sampling component 30, the sample container 40 can also be installed on the sampling component 30 through the insertion of the countersunk hole structure and the annular step, thereby improving the connection strength between the sample container 40 and the sampling component 30.

[0055] In addition, such as Figure 5 and Figure 7 As shown, to prevent relative rotation between the sample container 40 and the sampling component 30 after connection, the sampling inlet 13 can be designed as an oblong or elliptical orifice. Simultaneously, a connecting nozzle 35 protruding from the sampling component 30 can be provided. The shape of the connecting nozzle 35 matches the shape of the sampling inlet 13. When the sample container 40 and the sampling component 30 are connected, the connecting nozzle 35 inserted into the sampling inlet 13 can prevent relative rotation between the sample container 40 and the sampling component 30.

[0056] Correspondingly, such as Figure 9 As shown, a column portion 122 protruding from the plane of the cover plate 12 can also be provided on the cover plate 12. When the cover plate 12 is locked on the mating surface 15, the cover plate 12 can also be sealed on the cover body 11 by the insertion of the column portion 122 and the countersunk hole structure, which can not only improve the connection strength between the cover plate 12 and the cover body 11, but also improve the sealing performance between the cover plate 12 and the cover body 11.

[0057] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
