Detailed Description

The following description of the technical solutions according to the embodiments of the present utility model will be given with reference to the accompanying drawings in the embodiments of the present utility model, and it is apparent that the described embodiments are only some embodiments of the present utility model, 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 the present utility model, the terms "upper," "lower," "horizontal," and "vertical" are defined relative to the orientation in which the components are schematically depicted in the drawings, and it should be understood that these directional terms are relative terms, which are used for descriptive and clarity relative thereto, and which may be varied accordingly to the orientation in which the components are depicted in the drawings.

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

In the prior art, as shown in fig. 1, the cap portion of the sample container includes an outer cap and an inner cap. As shown in fig. 2, in order to enable the inner cap to be fitted into the outer cap, it is required to shrink a distance L inwardly at the top of the inner cap. Otherwise, the top of the inner cap is blocked outside the outer cap due to the overlarge circumferential size, so that the inner cap cannot be installed in the outer cap. However, the head space of the whole inner cap is sharply reduced, and the sampling passage is easily blocked during sampling.

The present utility model provides a sample container 100, as shown in fig. 3, the sample container 100 may include a sampling cap 10 and a sampling container 20. The sampling cap 10 may be connected to a sampling assembly (not shown) to form a sampling device. The sampling device can be matched with an endoscope with an extraction pipeline such as a gastroscope, a enteroscope, a cystoscope, a thoracoscope and the like for extracting pathological effusion of human body parts such as a thoracic cavity, an abdominal cavity, a pelvic cavity and the like.

Therein, as shown in fig. 4, the sampling cap 10 may include an outer cap 11 and an inner cap 12. The inner cap 12 may be sleeved in the outer cap 11, and the sampling vessel 20 may be detachably connected to the inner cap 12, wherein the detachable connection manner includes, but is not limited to, a threaded connection or a snap connection. The sample container 100 may be collected in the sampling container 20 by the sampling cap 10 after receiving the pathological liquid product drawn from the sampling assembly.

Specifically, as shown in fig. 5, the outer cover 11 may be designed as a box structure having a hollow interior. A first opening 111 may be provided in the front end of the outer cover 11 for interfacing with the sampling assembly. A second opening 112 may be provided below the outer cover 11 for connection with the sampling vessel 20. The inner cap 12 may be installed and sleeved inside the outer cap 11. A rotatable cover plate may be attached to the top of the outer cover 11, and the cover plate may cover the first opening 111.

Further, as shown in fig. 6, the inner cap 12 may include a first tube section 121 and a second tube section 122, the first tube section 121 and the second tube section 122 being in communication with each other. The port of the first tube segment 121 is a sampling inlet 13 (shown in fig. 4) for communication with a sampling assembly. The second tube segment 122 is ported to the sampling outlet 14 (shown in fig. 4) for communication with the sampling vessel 20. Wherein, the diameter of the first pipe section 121 is the same as the diameter of the sampling inlet 13, and the diameter of the second pipe section 122 is the same as the diameter of the sampling outlet 14.

Thus, as shown in fig. 7, when the pathological liquid product flows into the inner cap 12 from the sampling inlet 13, it falls directly into the sampling container 20 from the sampling outlet 14. Because the first pipe section 121 extending along the caliber of the sampling inlet 13 is directly communicated with the second pipe section 122 extending along the caliber of the sampling outlet 14, the problem of space reduction of the sampling channel of the inner cover 12 is avoided, so that pathological effusion including viscous liquid such as sputum is not easy to be blocked in the sampling channel of the inner cover 12.

It should be noted that, since the sampling inlet 13 needs to be connected to the sampling assembly, the first tube section 121 may be configured to have a waist shape, an oval shape, or a rectangular shape in order to prevent relative rotation between the sampling cap 10 and the sampling assembly. Thus, when the sampling assembly is connected to the sampling cap 10, the non-circular connection portion can prevent relative rotation between the sampling cap 10 and the sampling assembly. The shape of the second tube segment 122 may be the same as the shape of the passageway of the sampling vessel 20. Accordingly, the first pipe section 121 and the second pipe section 122 may be provided in the same shape or may be provided in different shapes. The shape of the first pipe section 121 and the second pipe section 122 is not particularly limited in the present utility model.

In fact, as shown in fig. 7, since the shape of the first pipe section 121 is the same as the shape of the sampling inlet 13, the shape of the second pipe section 122 is the same as the shape of the passage of the sampling vessel 20. The diameter of the sampling inlet 13 is smaller than that of the passage of the sampling container 20, that is, the diameter of the second pipe section 122 is larger than that of the first pipe section 121. In this way, the sampling channel is not only not reduced but is also enlarged during the flow of pathological effusion from the first tube section 121 into the second tube section 122, thereby further avoiding the problem of clogging of the pathological effusion in the sampling cap 10. Of course, the pipe diameter of the first pipe section 121 may be set to be the same as the pipe diameter of the second pipe section 122.

In installation, as shown in fig. 7, the top of the inner cap 12 may be fitted into the outer cap 11 from the second opening 112 (shown in fig. 5) of the outer cap 11 such that the sampling inlet 13 of the inner cap 12 is located at the first opening 111 (shown in fig. 5) of the outer cap 11. Then, the inner cap 12 is plugged into the outer cap 11, so that the sampling outlet 14 of the inner cap 12 is located at the second opening 112 of the outer cap 11, and the installation of the sampling cap 10 is completed.

In some embodiments, as shown in fig. 8, a docking surface 127 may be further disposed at a port position of the first pipe section 121, and the sampling inlet 13 may be disposed within a range of the docking surface 127. The shape of the abutment surface 127 can be adapted to the shape of the first opening 111 in the outer cap 11. When the inner cap 12 is fitted into the outer cap 11, the outer circumference of the abutment surface 127 can be fitted into the first opening 111, so that the inner cap 12 is fixed at the first opening 111 at the sampling inlet 13.

On this basis, as shown in fig. 8, a seal side wall 128 may also be provided along the circumferential direction of the abutment surface 127. By way of example, the sealing sidewall 128 may be provided in a configuration having an internal groove. In this way, the inner wall of the sealing sidewall 128 may be used to mount a sealing ring to improve the sealing performance of the sampling channel in the sampling cap 10. Meanwhile, the outer wall of the sealing side wall 128 can be attached to the first opening 111, so that the connection stability of the inner cover 12 is improved.

In order to avoid the top of the inner cap 12 from being blocked by the outer cap 11 at the time of installation, as shown in fig. 7, an installation gap S may be provided between the outer cap 11 and the top of the inner cap 12. When the inner cap 12 is pushed into the outer cap 11 after the top height of the inner cap 12 is lowered, the outer cap 11 does not block the inner cap 12. Of course, the circumferential direction of the inner cap 12 may be retracted inward by the distance T. Thus, the height of the top of the inner lid 12 lowered can be appropriately reduced, and the inner lid 12 can be similarly inserted into the outer lid 11. The present utility model is not particularly limited to the installation gap S and the setback distance T.

It should be noted that, no matter how the installation gap S and the retraction distance T between the outer cover 11 and the inner cover 12 are set, the pipe diameter setting of the first pipe section 121 and the second pipe section 122 of the inner cover 12, which are both of a fixed size, is always not affected. So as to ensure that the sampling passage in the inner cap 12 does not have a problem of space reduction, thereby enabling pathological effusion, particularly viscous sputum, to be smoothly collected in the sampling container 20 without causing clogging.

In some embodiments, as shown in fig. 6, a gripping portion 123 may be provided on top of the inner cover 12. For example, the tightening part 123 may include a first tightening plate 1231 and a second tightening plate 1232, and the first tightening plate 1231 and the second tightening plate 1232 may be disposed to cross in a cross-shaped structure. In this way, when the inner cap 12 is fitted into the outer cap 11, the inner cap 12 can be secured in place in the outer cap 11 by the tightening portion 123 tightening against the outer cap 11, and no relative misalignment between the outer cap 11 and the inner cap 12 occurs.

Wherein, as shown in fig. 6, the top of the inner cover 12 can be set to be a plane, so that the first propping plate 1231 and the second propping plate 1232 are perpendicular to the top plane of the inner cover 12, and therefore, the first propping plate 1231 and the second propping plate 1232 can play a better propping effect between the outer cover 11 and the inner cover 12 under the condition of least material consumption.

The first and second tightening plates 1231 and 1232 may be disposed in parallel or in other positional relationship, and the specific number and relative positional relationship of the first and second tightening plates 1231 and 1232 are not particularly limited in the present utility model. In addition, the tightening part 123 may be configured in a hemispherical shape or a truncated cone shape, and the present utility model is not limited to the structural form of the tightening part 123.

In order to prevent axial movement of the inner cap 12 along the sampling vessel 20 after installation, a first stopper 125 may be provided on the inner cap 12 and a second stopper 113 may be provided on the outer cap 11, as shown in fig. 5 and 6. For example, a limiting groove may be formed on the inner sidewall of the outer cover 11 as the second limiting portion 113, and the limiting groove is disposed along the axial direction of the second pipe section 122. A connecting wall 124 may be further disposed along the circumference of the sampling outlet 14 of the second pipe section 122, and a limiting protrusion may be disposed on the outer side of the connecting wall 124 as a first limiting portion 125.

When the sampling cap 10 is assembled, when the inner cap 12 is assembled into the outer cap 11, the limiting protrusion can slide into the limiting groove along one end of the limiting groove, and the limiting protrusion can be abutted against the other end of the limiting groove, so that the inner cap 12 is prevented from axially moving along the sampling container 20 in the outer cap 11.

It is to be understood that the first limiting portion 125 and the second limiting portion 113 may be provided in multiple groups, and the specific number of the first limiting portion 125 and the second limiting portion 113 is not limited in the present utility model. In addition, the first limiting portion 125 may be provided in a barb structure, and when the inner cap 12 is mounted in the outer cap 11, the barb on the inner cap 12 may hook the edge of the outer cap 11, and also prevent the inner cap 12 from moving in the outer cap 11. At this time, the setting of the second stopper 113 may also be canceled. The specific structures of the first limiting portion 125 and the second limiting portion 113 are not particularly limited in the present utility model.

On the basis of this, as shown in fig. 5 and 6, a first locking portion 126 may be provided on the inner cover 12, and a second locking portion 114 may be provided on the outer cover 11. When the inner cap 12 is fitted into the outer cap 11, the inner cap 12 can be locked in the outer cap 11 by the engagement of the first locking portion 126 and the second locking portion 114, thereby ensuring the stability of the connection between the inner cap 12 and the outer cap 11 and preventing the inner cap 12 from being separated from the outer cap 11.

As shown in fig. 5 and 6, the first locking portion 126 may be configured as a chuck, and the second locking portion 114 may be configured as a slot. When the chuck is snapped into the chuck slot, the inner cap 12 is installed in the outer cap 11. Of course, the first locking portion 126 may be provided in the form of a lock head, and the second locking portion 114 may be provided in the form of a lock hole. The specific structure of the first locking portion 126 and the second locking portion 114 is not particularly limited in the present utility model.

The foregoing is merely illustrative of the present utility model, and the present utility model is not limited thereto, and any person skilled in the art will readily recognize that variations or substitutions are within the scope of the present utility model. Therefore, the protection scope of the present utility model shall be subject to the protection scope of the claims.
